DETAILED DESCRIPTION

The embodiments of the present disclosure are described below in detail. Examples of the embodiments are shown in the accompanying drawings, and same or similar reference signs in all the accompanying drawings indicate same or similar assemblies or assemblies having same or similar functions. The embodiments described below with reference to the accompanying drawings are examples, are to explain the present disclosure and cannot be construed as a limitation on the present disclosure.

The turnout structure 100 provided in the embodiments of the present disclosure is described below with reference to the drawings from FIG. 1 to FIG. 24.

The turnout structure 100 according to the embodiment of the present disclosure includes at least one single turnout 10; in other words, the turnout structure 100 may include one single turnout 10 or multiple single turnouts 10. Wherein, when the turnout structure 100 is composed of multiple single turnouts 10, the structures of the multiple single turnouts 10 are same.

In an embodiment, the turnout structure 100 according to the embodiment of the present disclosure can be used in the rail transit system 1000, so that the rail transit system 1000 provided with the turnout structure 100 has the same advantages as the turnout structure 100.

The turnout structure 100 provided in the embodiments of the present disclosure is described below with reference to the drawings from FIG. 1 to FIG. 19.

The single turnout 10 includes a fixed beam set 11 and a movable beam set 12, the fixed beam set 11 includes a first side beam 111 and a second side beam 112 which are arranged/disposed oppositely, the movable beam set 12 is movably arranged/disposed between the first side beam 111 and the second side beam 112 to define two switchable driving channels R, the top surface of the movable beam set 12 is configured as a first locomotion surface 105 for locomotion wheels of a railway vehicle 200 to travel. As shown in FIG. 16 and FIG. 17, the first side beam 111 is a straight rail which extends along a straight line, the second side beam 112 is an arc rail which extends along an arc line, and the distance between the second side beam 112 and the first side beam 111 is gradually increased in the forward direction of the railway vehicle 200, as shown in FIG. 18 and FIG. 19, the first side beam 111 and the second side beam 112 are arc rails, the first side beam 111 and the second side beam 112 can extend along a set of symmetrical arc lines so that the single turnout 10 is configured as a split turnout.

The movable beam set 12 and the first side beam 111 can define a first driving channel R1. After the movable beam set 12 moves, the movable beam set 12 and the second side beam 112 can define a second driving channel R2. It should be noted that the top surface of the first side beam 111 and the top surface of the second side beam 112 are configured as the second locomotion surface 106 for the railway vehicle 200. The two sets of locomotion wheels of the railway vehicle 200 can move on the top surface of the movable beam set 12 and the top surface of the first side beam 111, or move on the top surface of movable beam set 12 and the top surface of the second side beam 112 respectively.

The railway vehicle 200 is provided with a bogie 230, and the bogie 230 is provided with a locomotion wheel 210 and a guide wheel 220. Every carriage is provided with two bogies 230, and the two bogies 230 are separated in the extension direction of the driving channel R.

In an embodiment, on each bogie 230, there are two separated locomotion wheels 210 in the width direction of the driving channel R, and there are four guide wheels 220, two guide wheels 220 are separated in the width direction of the driving channel R, the other two guide wheels 220 are separated in the width direction of the driving channel R and also are separated with the above-mentioned two guide wheels 220 in the extension direction of the driving channel R.

The rotation axis of the locomotion wheel 210 can extend in the horizontal direction, and the rotation axis of the guide wheel 220 can extend in the vertical direction. After the first driving channel R1 is defined between the movable beam set 12 and the first side beam 111, the two sets of locomotion wheels 210 roll on the top surface of the first side beam 111 and the top surface of the movable beam set 12 respectively, and the two sets of guide wheels 220 roll on the opposite side surfaces of the first side beam 111 and the movable beam set 12 respectively, that is to say, the first driving channel R1 includes the top surfaces of the first side beam 111 and the movable beam set 12, and the opposite side surfaces of the first side beam 111 and the movable beam set 12. After the second driving channel R2 is defined between the movable beam set 12 and the second side beam 112, the two sets of locomotion wheels 210 roll on the top surface of the movable beam set 12 and the top surface of the second side beam 112 respectively, and the two sets of guide wheels 220 roll on the opposite side surfaces of the movable beam set 12 and the second side beam 112 respectively, that is to say, the second driving channel R2 includes the top surfaces of the second side beam 112 and the movable beam set 12, and the opposite side surfaces of the second side beam 112 and the movable beam set 12.

The first side beam 111 and the second side beam 112 do not intersect with each other or overlap with each other, and they both extend along the forward direction of the railway vehicle 200. Since the railway vehicle 200 can choose different traveling directions at the single turnout 10, the first side beam 111 and the second side beam 112 can extend along different traveling directions respectively. The movable beam set 12 can move between the first side beam 111 and the second side beam 112, while the movable beam set 12 is moving, the single turnout 10 can present two driving channels R, wherein each driving channel R shows a different direction to guide the railway vehicle 200, what is more, only one of the two driving channels R can be used by the railway vehicle 200 at the same time. Therefore, it means that the two driving channels R are switchable.

As shown in FIG. 1, FIG. 15 to FIG. 19, the movable beam set 12 includes a rotating beam 121 and a moving beam 122. There is a rotating center 101 on one end (e.g., a first end) of the rotating beam 121, and the other end (e.g., a second end) of the rotating beam 121 is connected to the moving beam 122. The rotating beam 121 can rotate around the rotating center 101. That is to say, while the rotating beam 121 rotates around the rotating center 101, the movement track of the connection of the moving beam 122 and the rotating beam 121 is the same as the movement track of the other end of the rotating beam 121, since the other end of the rotating beam 121 is connected to the moving beam 122.

Since the moving beam 122 is connected to the other end of the rotating beam 121, the movement track of the end of the moving beam 122 connected to the rotating beam 121 is the same as the movement track of the other end of the rotating beam 121, while the other end of the rotating beam 121 is moving, the moving beam 122 can form an arc-shaped preset path Kl under its influence. The moving beam 122 can move along the preset path K1.

Therein, since the moving beam 122 is connected to the other end of the rotating beam 121, and the moving beam 122 can move along the arc-shaped preset path, the other end of the rotating beam 121 can move along the arc-shaped preset path together with the moving beam 122. Since the rotating center 101 is provided on one end of the rotating beam 121, when the other end of the rotating beam 121 moves along the arc-shaped preset path, the rotating beam 121 rotates around the rotating center 101 simultaneously.

Understandably, the moving beam 122 is movable along the arc-shaped preset path and the rotating beam 121 can rotate around the rotating center 101 of one end of the rotating beam 121, the other end of the rotating beam 121 is connected to the moving beam 122, thus, it suggests that the other end of the rotating beam 121 is pivotally connected to the moving beam 122, and the pivot center is located at the other end of the rotating beam 121. In other words, the moving beam 122 moves along an arc-shaped preset path, and on the other hand, the moving beam 122 is pivotally connected to the other end of the rotating beam 121 through its end of the length direction.

The turnout structure 100 according to the embodiment of the present disclosure, the movable beam set 12 is not an integral structure as in the prior art, it is composed of a rotating beam 121 and a moving beam 122, and the two beams are pivotally connected, the movable beam set 12 in the prior art is an integral structure, and the top surface of the movable beam set 12 should meet the requirement that at least the top surface can form part of the driving channel R in different directions, this also demands that the top surface of the movable beam set 12 should be wide enough to meet the requirement of travelling in different directions, for these reasons, the overall structure of the movable beam set 12 is bulky and it is difficult to manufacture the movable beam set 12.

In an embodiment, the turnout in the prior art is a slider type turnout, the slider moves between two side beams to form different driving channels R. The shape of the slider is generally triangular, and the two long sides of the triangle are used as part of different driving channels R, the section between two long sides is useless, for this reason, the overall volume of the movable beam set 12 is large and the structure of the movable beam set 12 is bulky.

The movable beam set 12 according to the embodiment is composed of a rotating beam 121 and a moving beam 122, and the two beams are pivotally connected. No matter in the first driving channel R1 state or in the second driving channel R2 state, the movable beam set 12 is used as part of the driving channel R, which means that the movable beam set 12 can be reused, redundant structures do not exist, so the movable beam set 12 is small in size, light in weight, and flexible when it is rotating. Therefore, the top surface of the movable beam set 12 does not need to be too wide, and the top surface of the movable beam set 12 can meet the travelling requirements in different directions when changing the relative positions of the rotating beam 121 and the moving beam 122. The size of the movable beam set 12 in the embodiment of the present disclosure does not need to be too large at least in the width direction, thereby the volume of the movable beam set 12 is greatly reduced. The movable beam set 12 is lighter in weight and is more flexible when it is rotating. In addition, it is less difficult to manufacture the movable beam set 12.

Understandably, compared with the triangular slider in the prior art, the two long sides of the triangle are respectively used as part of different driving channels R. The turnout structure with a larger turning radius has a longer distance between the two long sides of the triangle, the overall size of the slider is larger, therefore, compared with the turnout structure with a larger turning radius in the prior art, the volume of the turnout structure 100 is greatly reduced and the weight of the turnout structure 100 is greatly dropped according to the embodiment of the present disclosure.

In an embodiment according to the present disclosure, the turnout structure 100 also includes a first guide rail 131, which is configured as a straight guide rail. The first guide rail 131 is arranged below the moving beam 122, and the moving beam 122 can move along a preset path on the first guide rail 131. As shown in FIG. 1, the moving beam 122 moves along the preset path K1 on the first guide rail 131.

Since the moving beam 122 is connected to the other end of the rotating beam 121, the movement track of the end of the moving beam 122 connected to the rotating beam 121 is the same as the movement track of the other end of the rotating beam 121. The movement track of the moving beam 122 can be consistent with the movement track of the other end of the rotating beam 121, thus it can be seen, an arc-shaped preset path KI is formed. The moving beam 122 can move along the preset path K1.

At the same time, the moving beam 122 can move on the first guide rail 131, and the movement track of the end connected to the rotating beam 121 is arc-shaped. In order to ensure that the moving beam 122 and the first guide rail 131 do not interfere mutually, for instance, the moving beam 122 can move in the direction parallel to the extension direction of the first guide rail 131, for another, the moving beam 122 can move in the direction orthogonal to the extension direction of the first guide rail 131. The movement track of the moving beam 122 is obtained by combining the movement track along the extension direction of the first guide rail 131 and the movement track in the direction orthogonal to the extension direction of the first guide rail 131. Therefore, as shown in FIG. 1, the movement track of the moving beam 122 is also arc-shaped, that is, the above-mentioned preset path K1 of the moving beam 122 is an arc-shaped path.

In an embodiment, as shown in FIG. 2, FIG. 7 to FIG. 8, FIG. 11 and FIG. 13, the moving beam 122 includes a moving beam connection end connected to the rotating beam 121. The first guide rail 131 is arranged below the moving beam connection end; therefore, the first guide rail 131 can not only guide the moving beam 122 but also support the other end of the rotating beam 121 strongly.

In some embodiments of the present disclosure, the turnout structure 100 further includes a first moving assembly 15 which is arranged between the first guide rail 131 and the moving beam 122. The first moving assembly 15 is arranged between the first guide rail 131 and the moving beam 122, and the first moving assembly 15 can move in the first direction along the first guide rail 131, meanwhile the moving beam 122 is movably arranged on the first moving assembly 15, and the moving beam 122 can move in the second direction relative to the first moving assembly 15. An intersection angle is formed between the first direction and the second direction, for example, the intersection angle between the first direction and the second direction may be 30°, or 60°, or 90°.

In an embodiment, the first direction is the same as the extension direction of the first guide rail 131, the second direction and the first direction may be orthogonal to each other, and the intersection angle between the first direction and the second direction is 90°.

Further, as shown in FIG. 12, a first sliding member 141 extending along the second direction is arranged on the first moving assembly 15, and a second sliding member is arranged on the moving beam 122. The first sliding member 141 slidably mates/couples with the second sliding member.

In an embodiment, the first sliding member 141 is configured as a slide rail or a slide groove and it extends in the second direction, and the second sliding member is configured as a slider and it is arranged on the moving beam. Therefore, during the movement of the moving beam 122, the slider can move in the first direction together with the first sliding member 141, and it can move in the second direction along the slide rail or slide groove simultaneously.

In some embodiments of the present disclosure, as shown in FIG. 2 to FIG. 6, FIG. 11 to FIG. 12, the first moving assembly 15 includes a first rolling wheel frame 151 and a first rolling wheel 152. The first rolling wheel frame 151 is connected to the first sliding member 141. The first rolling wheel 152 is pivotally arranged on the first rolling wheel frame 151, and it is configured for rolling along the top surface of the first guide rail 131. When the first rolling wheel 152 rolls along the top surface of the first guide rail 131, the moving beam 122 moves along the extension direction of the first guide rail 131.

Further, the first moving assembly 15 includes a first stopping wheel 153 and a second stopping wheel 154. The first stopping wheel 153 and the second stopping wheel 154 are arranged on the first rolling wheel frame 151. The first stopping wheel 153 and the second stopping wheel 154 are clamped on the two sides of the first guide rail 131 in the width direction of the first guide rail.

The first stopping wheel 153 and the second stopping wheel 154 are located below the two sides of the first rolling wheel 152. When the first rolling wheel 152 rolls along the top surface of the first guide rail 131, the first stopping wheel 153 or the second stopping wheel 154 can clench the corresponding side of the first guide rail 131 in the width direction, thereby the first rolling wheel 152 dropping down from the top surface of the first guide rail 131 can be avoided when it rolls on the top surface of the first guide rail 131.

Still further, there are two first rolling wheels 152, and they are separated in the extension direction of the first guide rail 131. Likewise, the number of the first stopping wheel 153 or the second stopping wheel 154 is two. The two first stopping wheels 153 are separated in the extension direction of the first guide rail 131, the two second stopping wheels 154 are separated in the extension direction of the first guide rail 131. The first stopping wheels 153 and the corresponding second stopping wheels 154 are clamped on the two sides of the first guide rail 131 in the width direction.

The two first stopping wheels 153 are separated at the same side of the first guide rail 131, and the two second stopping wheels 154 are separated at the other side of the first guide rail 131. Thus, the moving beam 122 can move smoothly along the first guide rail 131 in the extension direction when it is driven. Even if the first moving assembly 15 is arranged between the end of the moving beam 122 connected to the rotating beam 121 and the first guide rail 131, the end of the moving beam 122 far away from the rotating beam 121 can still be dragged.

In an embodiment, the first guide rail 131 has an I-shaped cross section. The first guide rail 131 includes a first top plate 131a, a first bottom plate 131b, and a first connecting plate 131c connected to the first top plate 131a and the first bottom plate 131b. The first stopping wheel 153 and the second stopping wheel 154 are clamped on the two sides of the first top plate 131a that are opposite to each other in the width direction.

The first top plate 131a extends in the horizontal direction, so both of the two sides of the first top plate 131a in the width direction are smaller in size, but the rolling of the first stopping wheel 153 or the second stopping wheel 154 on the two sides of the first top plate 131a in the width direction is not affected.

According to another embodiment of the present disclosure, as shown in FIG. 7 to FIG. 8, a first inclined surface 102 and a second inclined surface 103 are opposite to each other, and they are arranged on the first guide rail 131 in the width direction. The first inclined surface 102 and the second inclined surface 103 gradually approach to each other or move away from each other in the direction from a bottom to a top of the first guide rail, the first inclined surface 102 and the second inclined surface 103 have different inclination directions.

The first moving assembly 15 includes a second rolling wheel frame 161, a second rolling wheel 162, and a third rolling wheel 163. The second rolling wheel frame 161 can be connected to the first sliding member 141. The second rolling wheel 162 and the third rolling wheel 163 are arranged on the second rolling wheel frame 161, and the second rolling wheel 162 or the third rolling wheel 163 can roll on the first inclined surface 102 or the second inclined surface 103 respectively.

In other words, when the second rolling wheel 162 cooperating with the first inclined surface 102, the third rolling wheel 163 cooperating with the second inclined surface 103, the second rolling wheel 162 and the third rolling wheel 163 can move along the first guide rail 131 in the extension direction, the second rolling wheel 162 or the third rolling wheel 163 can clench the corresponding inclined surface 102 or 103, what is more, the second rolling wheel 162 or the third rolling wheel 163 can be supported on the corresponding inclined surface 102 or 103. Thereby the first moving assembly 15 dropping down from the first guide rail 131 can be avoided, and the first moving assembly 15 can move stably on the first guide rail 131.

In an embodiment according to the present disclosure, a boss 131d is arranged on the top surface of the first guide rail 131, and the side surfaces of the boss 131d facing each other in the width direction of the first guide rail 131 are configured as the first inclined surface 102 and the second inclined surface 103 respectively. The first inclined surface 102 and the second inclined surface 103 gradually approach to each other in the direction from bottom to top. Therefore, when the first moving assembly 15 moves along the first guide rail 131, the boss 131d is clenched by the second rolling wheel 162 and the third rolling wheel 163.

According to another embodiment of the present disclosure, a groove is arranged on the top surface of the first guide rail 131. The side surfaces of the groove facing each other in the width direction of the first guide rail 131 are configured as the first inclined surface 102 and the second inclined surface 103. The first inclined surface 102 and the second inclined surface 103 gradually move away from each other in the direction from bottom to top. Therefore, when the first moving assembly 15 moves along the first guide rail 131, the second rolling wheel 162 or the third rolling wheel 163 can be supported on the inner wall of the groove.

In some embodiments of the present disclosure, as shown in FIG. 2 to FIG. 13, the turnout structure 100 further includes a second guide rail 132, which is configured as a straight guide rail. The second guide rail 132 is arranged below the moving beam 122, and the moving beam 122 can move along a preset path on the second guide rail 132. The second guide rail 132 can support the moving beam 122, thereby the moving stability of the moving beam 122 is improved.

Further, the turnout structure 100 includes a second moving assembly 17, which is arranged between the second guide rail 132 and the moving beam 122. The second moving assembly 17 can move in the third direction along the second guide rail 132, the moving beam 122 is movably arranged on the second moving assembly 17, and the moving beam 122 moves in the fourth direction relative to the second moving assembly 17. An intersection angle is formed between the third direction and the fourth direction, for example, the intersection angle between the third direction and the fourth direction may be 30°, or 60°, or 90°.

In an embodiment, the third direction is the same as the extension direction of the second guide rail 132, the fourth direction and the third direction may be orthogonal to each other, and the intersection angle between the fourth direction and the third direction is 90°.

According to an embodiment of the present disclosure, the first guide rail 131 and the second guide rail 132 are arranged in parallel, so the first guide rail 131 and the second guide rail 132 extend in the same direction. The first direction and the third direction are the same, and the second direction is orthogonal to the first direction. The fourth direction is orthogonal to the third direction, so the second direction and the fourth direction are the same.

Still further, as shown in FIG. 12, a third sliding member 142 extending along the fourth direction is arranged on the second moving assembly 17, and a fourth sliding member is arranged on the moving beam 122. The third sliding member 142 slidably mates with the fourth sliding member.

In an embodiment, the third sliding member 142 is configured as a slide rail or a slide groove and it extends in the fourth direction, the third sliding member 142 is arranged on the second moving assembly 17. The fourth sliding member is configured as a slider and it is arranged on the moving beam 122. Therefore, during the movement of the moving beam 122, the slider can move in the third direction, and it can move in the fourth direction along the slide rail or slide groove simultaneously.

In some embodiments of the present disclosure, the second moving assembly 17 includes a third rolling wheel frame 171 and a fourth rolling wheel 172. The third rolling wheel frame 171 is connected to the third sliding member 142. The fourth rolling wheel 172 is pivotally arranged on the third rolling wheel frame 171, and it is configured for rolling along the top surface of the second guide rail 132. When the fourth rolling wheel 172 rolls along the top surface of the second guide rail 132, the moving beam 122 moves along the extension direction of the second guide rail 132.

In some embodiments of the present disclosure, the turnout structure 100 further includes a mounting plate 173, which is used for connecting the first moving assembly 15 and the second moving assembly 17. For example, the mounting plate 173 can connect the first moving assembly 15 and the second moving assembly 17 together. In an embodiment, the mounting plate 173 can be fixed to the first rolling wheel frame 151 or the third rolling wheel frame 171 respectively. Or the mounting plate 173 can be fixed to the second rolling wheel frame 161 or the third rolling wheel frame 171 respectively. In the description below, a driving motor 181 drives the first rolling wheel frame 151 to move along the length direction of the first guide rail 131, the driving motor 181 can also be fixed to the mounting plate 173. A pushing rod 192 connected to the linear driving unit 191 is also fixed to the mounting plate 173. Thereby, the mounting plate 173 is driven to move in the first direction or the third direction.

In an embodiment, the first rolling wheel frame 151 and the third rolling wheel frame 171 are fixed on the sides of the bottom surface of the mounting plate 173, and the first sliding member 141 and the third sliding member 142 are fixed on the sides of the top surface of the mounting plate 173. The first sliding member 141 faces directly towards the first rolling wheel frame 151 in the vertical direction, and the third sliding member 142 faces directly towards the third rolling wheel frame 171 in the vertical direction.

Even further, two guide rails are arranged below the movable beam set 12. One guide rail is the first guide rail 131, and it is located at the connection between the moving beam 122 and the rotating beam 121. The other guide rail is the second guide rail 132, and it is located below the moving beam 122. The second guide rail 132 is located at the side of the first guide rail 131 away from the rotating beam 121. Therefore, the first guide rail 131 can support the rotating beam 121; what is more, the moving beam 122 can be strongly supported by the first guide rail 131 and the second guide rail, so that the moving beam 122 can move smoothly along the first guide rail 131 and the second guide rail 132.

As shown in FIG. 15 to FIG. 19, the movable beam set 12 is movable between the first position and the second position to define a first driving channel R1 and a second driving channel R2. It is possible to switch between the two driving channels. Wherein, as shown in FIG. 16 and FIG. 18, when the movable beam set 12 moves to the first position, the moving beam 122 is in contact with the second side beam 112, meanwhile, the first driving channel R1 is jointly defined by the movable beam set 12 and the first side beam 111. As shown in FIG. 17 and FIG. 19, when the movable beam set 12 moves to the second position, the moving beam 122 is in contact with the first side beam 111, meanwhile, the second driving channel R2 is defined by the movable beam set 12 and the second side beam 112. Therefore, the structure of the single turnout 10 is simple, and it is convenient and reliable to switch between the two driving channels R.

In some embodiments of the present disclosure, the single turnout 10 further includes a driving device. The driving device is used to drive the movable beam set 12 to move relatively towards the fixed beam set 11. The driving device includes a driving unit and a transmission assembly.

In addition, the arrangement of the transmission rack and the transmission gear in the receiving groove 104 also increases the working life of the transmission assembly, and the transmission assembly is less susceptible to corrosion.

In some embodiments of the present disclosure, as shown in FIG. 11 and FIG. 12, the driving unit is configured as a linear driving unit 191, and the transmission assembly is configured as a pushing rod 192. One end of the pushing rod 192 is connected to the linear driving unit 191, and the other end of the pushing rod 192 is connected to the mounting plate.

Therefore, as shown in FIG. 16, when the movable beam set 12 moves to the first position, the straight channel is opened; as shown in FIG. 17, when the movable beam set 12 moves to the second position, the curved channel is opened.

In some embodiments of the present disclosure, as shown in FIG. 13 and FIG. 14, the single turnout 10 further includes a locking device, the locking device is used to lock the movable beam set 12 when the traffic channel R is limited. For example, when the movable beam set 12 moves to the first position, the first driving channel R1 is jointly defined by the movable beam set 12 and the first side beam 111, at this time, the locking device can lock the movable beam set 12 so that the first driving channel R1 remains in a stable condition. When the movable beam set 12 moves to the second position, the second driving channel R2 is defined by the movable beam set 12 and the second side beam 112, at this time, the locking device can lock the movable beam set 12 so that the second driving channel R2 remains in a stable condition.

A locking groove 108 is arranged on the locking seat 193. The locking head 194 is connected to the movable beam set 12 and it can move along with the movable beam set 12. The locking head 194 moves between the locked position when it matches the locking groove 108 and the unlocked position when it disengages from the locking groove 108. When the movable beam set 12 moves to the first position or the second position, the locking head 194 can be driven and it inserts into the locking groove 108.

Understandably, the movement of the locking head 194 between the locked position and the unlocked position requires a driving device, and the driving device is connected to the mounting plate 173. In an embodiment, the drive device can be configured as a locking cylinder 195, a telescopic rod of which is connected to the locking head 194.

A locking head hole used for the locking head 194 passing through is set on the locking head seat 197, and a first wear-resistant plate 198a is arranged on the inner peripheral wall of the locking head hole. Therefore, the first wear-resistant plate 198a has good wear resistance, the material loss of the first wear-resistant plate 198a caused by repeated friction between the locking head 194 and the first wear-resistant plate 198a is effectively reduced.

A second wear-resistant plate 198b is arranged on the inner peripheral wall of the locking groove 108. The free end of the second wear-resistant plate 198b is configured as a guide section 198c. The inner diameter of the guide section 198c increases gradually in the direction away from the first guide rail 131 or the second guide rail 132. The locking head 194 can be quickly positioned in the locking groove 108, so that the locking head 194 can cooperate with the locking groove 108 quickly.

The locking device further includes a first position sensor for detecting the movement of the movable beam set 12 to a preset position, a second position sensor for detecting the cooperation state between the locking head 194 and the locking groove 108. For example, the first position sensor can detect whether the movable beam set 12 moves to the first position or the second position, and the second position sensor can detect the cooperation state between the locking head 194 and the locking groove 108.
