The present invention relates to a crane assembling method.
Conventionally, there has been known a crane such as a luffing jib crane which includes a jib on a distal end of a boom or a tower crane. In such a large-sized crane having the jib, the jib has the split structure formed of a plurality of parts (partial jibs). In a site where the crane is used, the jib is assembled by connecting partial jibs to each other.
In general, the large-sized crane is assembled in a state where the crane is laid down on a ground such that the boom and the jib extend on one straight line (so called “lying-type assembly method”). However, in such a lying-type assembly method, it is necessary to ensure a space elongated in a horizontal direction so that the boom and the jib can be extended horizontally. However, when the large-sized crane is used, there is a possibility that it is impossible to ensure a sufficient space which allows the adoption of the lying-type assembly method in a work site.
In the case where a sufficient space cannot be ensured so that the lying-type assembly method cannot be adopted in assembling a crane, a method referred to as a “standing-type assembly method” is adopted where a jib is mounted on a boom in a state that the boom is raised. For example, JP-A-2008-81242 describes a crane assembling method where partial jibs are sequentially connected one by one to a distal end of a boom to assemble a crane.
In the crane assembling method of a crane described in the above-mentioned publication, firstly, the boom is mounted on a crane body, and a base end jib (a partial jib connected to the boom) is connected to a distal end of the boom laid down on a ground. Then, an upper side portion of a distal end of the base end jib and an upper side portion of a proximal end of an intermediate jib (a partial jib other than both ends) placed on the ground are joined to each other by a pin so that a temporary connection state is brought about where the intermediate jib is bent toward a back side (upper side) with respect to the base end jib. Next, ropes are extended between a strut supported on the boom above the base end jib and both ends of the intermediate jib. By raising the boom in a state where the intermediate jib is held horizontally, the boom is lifted in air while maintaining the temporary connection state where the base end jib and the intermediate jib are bent. Then, by slackening the above-mentioned ropes which hold the intermediate jib, the intermediate jib rotates relative to the base end jib due to its own weight. Then, by joining a lower side portion of a distal end of the base end jib and a lower side portion of a proximal end of the intermediate jib to each other by a pin, the intermediate jib is connected to the base end jib such that the intermediate jib extends straight with respect to the base end jib. At this stage of operation, to prevent the base end jib from excessively sagging downward more than a fixed angle with respect to the distal end of the boom, the crane described in the publication includes a back stop cylinder on a distal end portion of the boom. The back stop cylinder connects the distal end portion of the boom and the base end jib to each other thus preventing lowering of the base end jib.
The crane assembling method described in the above-mentioned publication is applicable to only a special crane which includes the back stop cylinder for preventing sagging of the base end jib.
Further, in the case of assembling a large-sized crane having a jib in a narrow space, a method is also considered where an upper side portion of a distal end of a base end jib and an upper side portion of a proximal end of an intermediate jib placed on a ground are joined to each other by a pin, both ends of the intermediate jib are separately lifted, and the intermediate jib is connected to the base end jib in a straight posture. However, such a method requires a sophisticated crane operating technique, and requires a particular attention for ensuring safety.
The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a crane assembling method which can easily assemble a large-sized crane having a jib.
To achieve the above-mentioned object, the present invention provides a crane assembling method of assembling a crane, the crane including: a crane body; a boom which is disposed on the crane body such that the boom is capable of being raised or laid down about a first rotary shaft which is disposed horizontally; a jib which is connected to a distal end of the boom such that the jib is capable of being raised or laid down about a second rotary shaft which is disposed horizontally, the jib being formed by connecting a plurality of partial jibs to each other in a longitudinal direction. The crane assembling method includes a partial jib connecting step of connecting an (n+1)th partial jib to a distal end of an nth partial jib, where n is a natural number, in a state where the boom is mounted on the crane body and is laid down and n pieces of the partial jibs are connected to the distal end of the boom. The partial jib connecting step includes a placing step, an upper side connector connecting step, a wheel mounting step, and a lower side connector connecting step. In the placing step, the distal end of the boom is separated upward from a ground, and a distal end of the nth partial jib connected to the boom is placed on the ground or a pedestal disposed on the ground. In the upper side connector connecting step, the (n+1)th partial jib is lifted and is moved near to the nth partial jib, and an upper side connector disposed on an upper side portion of a distal end of the nth partial jib and an upper side connector disposed on an upper side portion of a proximal end of the (n+1)th partial jib are connected to each other by a fixing pin which extends parallel to the second rotary shaft in a relatively rotatable manner. In the wheel mounting step, in a state where the (n+1)th partial jib is lifted, a wheel capable of rolling on the ground is mounted on a lower side connector disposed on a lower side portion of a distal end of the (n+1) partial jib. In the lower side connector connecting step, the nth partial jib is lifted using the second rotary shaft as a fulcrum so that the (n+1)th partial jib is rotated relative to the nth partial jib about the fixing pin while allowing rolling of the wheel on the ground, the lower side connector disposed on the lower side portion of the proximal end of the (n+1)th partial jib is moved near to the lower side connector disposed on the lower side portion of the distal end of the nth partial jib, and the lower side connector on the distal end of the nth partial jib and the lower side connector on the proximal end of the (n+1)th partial jib are connected to each other.
Hereinafter, an embodiment of the present invention is described with reference to drawings as appropriate.
[Crane]
The crane 100 is a luffing jib crane which includes: a lower traveling body 1; an upper turning body 2 (crane body) which is mounted on the lower traveling body 1 in a horizontally turnable manner; a boom 3 which is disposed on a front portion of the upper turning body 2 so as to be raised or laid down in a frontward and rearward direction (in a swingable manner such that the boom 3 is laid down in a frontward direction and is raised in a rearward direction); and a jib 4 which is connected to a distal end of the boom 3 so as to be capable of being raised or laid down in the frontward and rearward direction.
[Lower Traveling Body]
The lower traveling body 1 includes a pair of left and right crawlers (crawler belts) 5 as a traveling device.
[Upper Turning Body]
The upper turning body 2 includes: an operator's cabin 6; a boom raising winch 7 for raising the boom 3; a jib raising winch 8 for raising the jib 4; a winding winch 9 which is suspended from a distal end of the jib 4 and winds a rope for lifting a suspended load; and the like.
[Boom]
The boom 3 is formed by connecting a lower boom 10, a plurality of intermediate booms 11 and a tower cap 12 to each other in this order in a longitudinal direction of the boom 3. The lower boom 10 is mounted on the upper turning body 2. The jib 4 is connected to the tower cap 12. The lower boom 10 and the plurality of intermediate booms 11 respectively have the lattice structure where four main girders (columns) and a plurality of auxiliary girders (lattices) which connect the neighboring main girders to each other are provided so as to form an approximately rectangular cylindrical framework structural body. The boom 3 is configured to be raised or laid down using, as a fulcrum, a boom foot 3S disposed on a proximal end of the boom 3. The boom foot 3S forms a horizontal rotary shaft (first rotary shaft).
[Jib]
The jib 4 is formed by connecting a plurality of partial jibs (a lower jib 13, a plurality of intermediate jibs 14 and an upper jib 15) to each other along a longitudinal direction of the jib 4. The lower jib 13 is connected to a distal end of the boom 3. These partial jibs respectively have a lattice structure where four main girders (columns) and a plurality of auxiliary girders (lattices) which connect the neighboring main girders to each other are provided so as to form an approximately rectangular cylindrical or a quadrangular pyramid-shaped framework structural body. The jib 4 is configured to be raised or laid down using a jib foot 4S disposed on a proximal end of the jib 4 as a fulcrum. The jib foot 4S forms a horizontal rotary shaft (second rotary shaft) parallel to the first rotary shaft.
As shown in detail in
(Connector)
The back-side connector 16 and the front-side connector 17 can be formed of one or a plurality of plate-like bodies which are formed in a projecting manner in the longitudinal direction from an end portion of the main girder of the partial jib. The back-side connectors 16 which are connected to each other and the front-side connectors 17 which are connected to each other are disposed in a displaced manner such that the connected back-side connectors 16 and the front-side connectors 17 are disposed adjacently to each other in the horizontal direction respectively. Further, it is preferable that at least one of the pair of back-side connectors 16 which is connected to each other and at least one of the pair of front-side connectors 17 which is connected to each other be respectively formed of a plurality of plate-like bodies (see the connectors 16B in
(Wheel)
The wheel 19 has a shaft 19a (wheel rotary shaft) which is inserted into a hole (pin hole) of the front-side connector 17 into which the fixing pin 18 is inserted, and rotates about the shaft 19a. Accordingly, the shaft 19a is preferably provided with a bearing, a bushing or the like interposed between the shaft 19a and the hole, for example. Further, the shaft 19a is preferably be configured such that a retainer 19S (
[Assembling Method of Crane]
In the crane assembling method of a crane according to one embodiment of the present invention, the boom 3 is assembled to the upper turning body 2 and, thereafter, the jib 4 is assembled by sequentially connecting the partial jibs to the distal end of the boom 3 one by one.
The crane assembling method of a crane includes the steps of: assembling the boom 3 to the upper turning body 2 [boom assembling step]; connecting the lower jib 13 to a distal end of the boom 3 in a state that the lower jib 3 can be raised or laid down [lower jib connecting step]; connecting the intermediate jib 14 to the lower jib 13 or connecting another intermediate jib 14 to the most distal end of one or a plurality of intermediate jibs 14 connected to the lower jib 13 [intermediate jib connecting step]; and connecting the upper jib 15 to the most distal end of the plurality of intermediate jibs 14 connected to the lower jib 13 [upper jib connecting step]. The intermediate jib connecting step is repeated plural times corresponding to the number of intermediate jibs 14.
[Boom Assembling Step]
In the same manner as the usual lying-type assembly method, in the boom assembling step, the boom 3 is assembled in a state where the boom 3 is laid down on a ground, and is mounted on the upper turning body 2. Alternatively, the lower boom 10 may be mounted on the upper turning body 2 and, thereafter, the plurality of intermediate booms 11 and the tower cap 12 may be mounted on the lower boom 10 sequentially.
[Lower Jib Connecting Step]
In the lower jib connecting step, the lower jib 13 is mounted on a distal end of the boom 3 using an assembling crane AC (
[Intermediate Jib Connecting Step]
The intermediate jib connecting step (partial jib connecting step) is a step where, assuming that the number of partial jibs are expressed by natural number n where the lower jib 13 is counted as the first partial jib, the boom 3 is laid down simultaneously with the mounting of the boom 3 on the upper turning body 2, and in a state where n pieces of the partial jibs (the lower jib 13 or the lower jib 13 and one or a plurality of intermediate jibs 14) are connected to the distal end of the boom 3, an (n+1)th partial jib (another intermediate jib 14) is connected to a distal end of an n-th partial jib (the lower jib 13 or the intermediate jib 14 on a most distal end side out of the intermediate jibs 14 connected to the lower jib 13).
The intermediate jib connecting step (a step of connecting the (n+1)th partial jib) includes the steps of: placing a distal end of an n-th partial jib connected to the boom 3 on a pedestal S disposed on the ground in a state where the distal end of the boom 3 is separated from the ground in the upward direction <placing step>; connecting the back-side connector 16 on a proximal end side of the (n+1)th partial jib to the back-side connector 16 on a distal end side of the n-th partial jib in a state where the (n+1)th partial jib is lifted <back-side connector connecting step (upper side connector connecting step)>; mounting the wheel 19 on the front-side connector 17 on a distal end side of the (n+1)th partial jib <wheel mounting step>; and connecting the front-side connector 17 on a distal end side of n-th partial jib and the front-side connector 17 on a proximal end side of the (n+1)th partial jib to each other <front-side connector connecting step (lower side connector connecting step)>.
It is more preferable that the intermediate jib connecting step further include a step of moving a distal end of the (n+1)th partial jib close to a position where the distal end of the n-th partial jib is placed in the back-side connector connecting step of connecting the back-side connector on a proximal end side of the (n+1)th partial jib by raising the boom 3 <a moving step or a distal end moving step> after the front-side connector connecting step, for the next intermediate jib connecting step or the upper jib connecting step.
Hereinafter, the intermediate jib connecting step is described in more detail. In
<Placing Step>
In the placing step, firstly, as shown in
Next, as shown in
<Back-Side Connector Connecting Step>
In the back-side connector connecting step, as shown in
<Wheel Mounting Step>
In the wheel mounting step, as shown in
<Front-Side Connector Connecting Step>
In the front-side connector connecting step, as shown in
At this stage of the operation, the back-side connector 16 on the proximal end side of the intermediate jib 14 is moved so as to draw an arc about the jib foot 4S on the distal end of the boom 3 and hence, the position of the distal end portion of the intermediate jib 14 is changed. However, the distal end portion of the intermediate jib 14 is supported by the wheel 19 and hence, the distal end portion of the intermediate jib 14 smoothly moves along the ground. Accordingly, the assembling operation can be facilitated and, at the same time, it is possible to prevent the distal end portion of the intermediate jib 14 from being damaged.
In the front-side connector connecting step, the proximal end side of the lower jib 13 may be lifted without lifting the portion of the lower jib 13 near the connecting portion between the lower jib 13 and the intermediate jib 14 using the assembling crane AC. By lifting the portion of the lower jib 13 near the connecting portion between the lower jib 13 and the intermediate jib 14, the front-side connector 17 disposed on a lower side portion of the proximal end of the intermediate jib 14 can be easily moved near to the front-side connector 17 disposed on the lower side portion of the distal end of the lower jib 13.
<Distal End Moving Step>
In the distal end moving step, as indicated by an arrow in
Accordingly, at the time of repeating the above-mentioned intermediate jib connecting step for connecting the next intermediate jib 14 ((n+2)th partial jib) to a distal end of the intermediate jib 14 ((n+1)th partial jib) shown in
When the jib 4 includes two or more intermediate jibs 14 (n≥2), the above-mentioned intermediate jib connecting step is repeated. In this case, the above-mentioned lower jib 13 forms the “first-stage intermediate jib 14”, and the above-mentioned intermediate jib 14 forms the “second-stage intermediate jib 14”. The wheel 19 is removed before the intermediate jib 14 shown in
[Upper Jib Connecting Step]
The upper jib connecting step includes the steps of: placing a distal end of a most distal end intermediate jib 14 on a pedestal disposed on the ground in a state where the distal end of the boom 3 is separated from the ground <placing step>; connecting the back-side connector 16 on a proximal end side of the upper jib 15 to the back-side connector 16 on a distal end side of the most distal end intermediate jib 14 in a state where the upper jib 15 is suspended <back-side connector connecting step>; mounting a wheel 20 on a distal end portion of the upper jib 15 <wheel mounting step>; and connecting the front-side connector 17 on a distal end side of the most distal end intermediate jib 14 and the front-side connector 17 on a proximal end side of the upper jib 15 to each other <front-side connector connecting step>.
The placing step, the back-side connector connecting step, the wheel mounting step, and the front-side connector connecting step in the upper jib connecting step can be performed substantially in the same order as the placing step, the back-side connector connecting step, the wheel mounting step, and the front-side connector connecting step in the intermediate jib connecting step except for a point that the wheel 20 different from the wheel 19 mounted on the front-side connector 17 is mounted on the distal end portion of the upper jib 15 as shown in
For mounting the wheel 20 on the distal end portion of the upper jib 15, a dedicated bracket or the like may be provided on a front side of the distal end portion of the upper jib 15, and a cart capable of supporting the distal end portion of the upper jib 15 may be used as the wheel 20. Further, the wheel 20 may be a wheel formed by mounting an adapter on the wheel 19 mounted on the front-side connector 17 for mounting the wheel on the distal end portion of the upper jib 15.
<Advantageous Effects>
According to this crane assembling method, as described above, by connecting the partial jibs one by one to the boom 3 and by raising the boom 3 corresponding to a total length of the partial jibs connected to the boom 3, a length of a necessary working space in the horizontal direction can be made small. That is, according to this crane assembling method, the crane 100 can be assembled even at a place whose length is smaller than a total length of the boom 3 and the jib 4.
According to this crane assembling method, by mounting the wheel 19 on the front-side connector 17 on a distal end side of a newly connected (n+1)th partial jib, the (n+1)th partial jib can be moved in a state where the distal end of the (n+1)th partial jib is kept in contact with the ground. Accordingly, it is unnecessary to lift up the distal end side of the (n+1)th partial jib at the time of connecting the front-side connector 17 of the nth partial jib and the front-side connector 17 on the proximal end side of the (n+1)th partial jib to each other and hence, an assembling operation can be facilitated and can be performed safely and, at the same time, the assembling operation can be performed using only one assembling crane.
The configuration of the crane 100 shown in
The above-mentioned embodiment does not limit the configuration of the present invention. Accordingly, it should be construed that the above-mentioned embodiment can be modified by omission, replacement or addition of constitutional elements of respective parts of the embodiment based on the description of this specification and the common general technical knowledge, and all these modifications also fall within the scope of the present invention.
In the crane assembling method, a first partial jib may be a partial jib formed by connecting the lower jib and one or a plurality of intermediate jibs to each other, and the (n+1)th partial jib may be a connected body formed of a plurality of intermediate jibs.
According to the above-mentioned crane assembling method, in
In the placing step of the crane assembling method, provided that the back-side connector on a proximal end side of the (n+1)th partial jib can be connected to the back-side connector on a distal end side of the nth partial jib in the next back-side connector mounting step, the nth partial jib may be directly placed on the ground.
In the crane assembling method, plural sets of wheels may be used. With the use of the plural sets of wheels in this manner, the wheel can be mounted on the front-side connector 17 on a distal end side of the (n+2)th partial jib during a mounting operation of the (n+1)th partial jib and hence, an assembling operation can be performed smoothly.
In the crane assembling method, the distal end moving step may be performed before the front-side connector connecting step, or may be performed simultaneously with the front-side connector connecting step.
The crane assembling method is also applicable to assembling of a tower crane where a boom 3 is not raised or laid down during a period that the crane is used.
The crane assembling method according to the present invention is particularly preferably applicable to a large-sized luffing jib crane.
The present invention provides a crane assembling method of a crane, the crane including: a crane body; a boom which is disposed on the crane body such that the boom is capable of being raised or laid down about a first rotary shaft which is disposed horizontally; a jib which is connected to a distal end of the boom such that the jib is capable of being raised or laid down about a second rotary shaft which is disposed horizontally, the jib being formed by connecting a plurality of partial jibs to each other in a longitudinal direction. The crane assembling method includes a partial jib connecting step of connecting an (n+1)th partial jib to a distal end of an nth partial jib, where n is a natural number, in a state where the boom is mounted on the crane body and is laid down and n pieces of the partial jibs are connected to the distal end of the boom. The partial jib connecting step includes a placing step, an upper side connector connecting step, a wheel mounting step, and a lower side connector connecting step. In the placing step, the distal end of the boom is separated upward from a ground, and a distal end of the nth partial jib connected to the boom is placed on the ground or a pedestal disposed on the ground. In the upper side connector connecting step, the (n+1)th partial jib is lifted and is moved near to the nth partial jib, and an upper side connector disposed on an upper side (back-side) portion of a distal end of the nth partial jib and an upper side connector disposed on an upper side portion of a proximal end of the (n+1)th partial jib are connected to each other by a fixing pin which extends parallel to the second rotary shaft in a relatively rotatable manner. In the wheel mounting step, in a state where the (n+1)th partial jib is lifted, a wheel capable of rolling on the ground is mounted on a lower side connector disposed on a lower side (front-side) portion of a distal end of the (n+1) partial jib. In the lower side connector connecting step, the nth partial jib is lifted using the second rotary shaft as a fulcrum so that the (n+1)th partial jib is rotated relative to the nth partial jib about the fixing pin while allowing rolling of the wheel on the ground, the lower side connector disposed on the lower side portion of the proximal end of the (n+1)th partial jib is moved near to the lower side connector disposed on the lower side portion of the distal end of the nth partial jib, and the lower side connector on the distal end of the nth partial jib and the lower side connector on the proximal end of the (n+1)th partial jib are connected to each other.
In the above-mentioned configuration, the above-mentioned “back side” means a side disposed on an upper side in a state where the boom and the jib are extended and are laid down, and the above-mentioned “front-side” means a side disposed on a lower side in a state where the boom and the jib are laid down. Further, “distal end” means a side remote from the crane body (turning body) in a state where the boom and the jib are extended, and “proximal end” means a side near the crane body in a state where the boom and the jib are extended. Still further, “ground” means a surface of a steel plate or the like when curing is performed using a steel plate or the like.
According to the crane assembling method, by connecting the partial jibs one by one and by raising the boom corresponding to a total length of the connected partial jibs, a length of a necessary space in the horizontal direction can be made small. Further, according to the crane assembling method, by mounting the wheel on the lower side connector on the distal end of the newly connected (n+1)th partial jib, the (n+1)th partial jib can be moved in a state where the distal end of the (n+1)th partial jib is kept brought into contact with the ground. Accordingly, it is unnecessary to lift the distal end side of the (n+1)th partial jib in connecting the lower side connector of the nth partial jib and the lower side connector on the proximal end of the (n+1)th partial jib to each other and hence, the connecting operation of the partial jibs can be easily and safely performed. Further, the crane assembling method is applicable to assembling of an ordinary large-sized crane having a jib only by preparing a wheel capable of being mounted on the lower side connector and hence, the crane assembling method has the high general-purpose property.
In the lower side connector connecting step in the above-mentioned crane assembling method, it is preferable that the (n+1)th partial jib be rotated relative to the nth partial jib by lifting a portion of the nth partial jib near the connection portion between the nth partial jib and the (n+1)th partial jib.
With such a method, in the lower side connector connecting step, the lower side connector disposed on the lower side portion of the proximal end of the (n+1)th partial jib can be easily moved near to the lower side connector disposed on the lower side portion of the distal end of the nth partial jib.
It is more preferable that the above-mentioned crane assembling method further include a moving step of moving the distal end of the (n+1)th partial jib close to a position where the distal end of the nth partial jib is disposed in the upper side connector connecting step by raising the boom about the first rotary shaft while allowing rolling of the wheel on the ground after the lower side connector connecting step in the partial jib connecting step.
With such a method, a working area for connecting the (n+2)th partial jib becomes substantially equal to a working area used at the time of connecting the (n+1)th partial jib and hence, the crane can be assembled in a space having a relatively small distance in the horizontal direction and, at the same time, even when another assembling crane is relatively small so that a workable area of the assembling crane is small, it is unnecessary to largely move the assembling crane and hence, operation efficiency of the assembling operation of the crane can be enhanced.
It is preferable that a wheel having a wheel rotary shaft which is inserted into a pin hole formed in the lower side connector disposed on the distal end of the (n+1)th partial jib be prepared as the wheel, and the fixing pin be inserted into the pin hole of the lower side connector disposed on the distal end of the (n+1)th partial jib in the lower side connector connecting step in a step of connecting an (n+2)th partial jib to the distal end of the (n+1)th partial jib.
With such a method, the configuration of the wheel can be simplified and, at the same time, mounting of the wheel on the lower side connector can be facilitated and hence, operation efficiency of the crane assembling method can be enhanced. Further, the mounting position of the wheel and the connection position of the connector can be utilized in common and hence, it is unnecessary to form a large number of opening portions in the connector thus suppressing lowering of rigidity of the connector.
