Patent Application
20240279878
The present disclosure relates to a tool for aligning rails segments with each other to form a rail line, e.g., at a worksite.
Various applications implemented at worksites, such as mine sites, use rail lines for the transfer of material, power, personnel, and the like. To produce a rail line (e.g., a single rail line), typically, multiple rail segments are serially connected one after the other. For enabling connections between the rail segments, adjoining rail segments of the rail line are generally required to be aligned to each other. Depending upon the type of application, some rail lines may need to be elevated above a ground level, and, in such cases, support may be provided from below or underneath each rail segment so as to elevate the rail line above the ground level. While forming or assembling rail segments at an elevation to form the rail line, as individual rail segments may be positioned above a support, end portions of those rails segments may sag or tend to curve downwards towards the ground, thus making one rail segment's alignment with an adjoining rail segment difficult.
U.S. Pat. No. 8,684,279 relates to a railroad alignment system for lifting and aligning railroad tracks during installation. The railroad alignment system generally includes a first vertical support and a second vertical support with a horizontal support extending therebetween. The vertical supports are vertically adjustable through use of a pair of adjustment members. A clamp assembly extends downwardly from the horizontal support at a position midway between the first vertical support and second vertical support. Through use of a pair of adjustment members, the clamp assembly may be closed to secure a track in place for alignment and lifting.
In one aspect, the disclosure relates to a tool for aligning a first rail segment with a second rail segment. The tool includes an elongated rigid member, a first arrangement, and a second arrangement. The elongated rigid member is configured to be positioned in an overlapping state with respect to each of the first rail segment and the second rail segment. The first arrangement is configured to engage a first end portion of the first rail segment and be actuated to urge the first end portion towards the elongated rigid member. The second arrangement is configured to engage a second end portion of the second rail segment and be actuated to urge the second end portion towards the elongated rigid member. When each of the first end portion and the second end portion is urged towards the elongated rigid member, the first rail segment and the second rail segment adjoin and fall in alignment with each other to be connected together and form a contiguous rail portion of a rail line.
In another aspect, the disclosure is directed to a method for aligning a first rail segment with a second rail segment. The method includes positioning an elongated rigid member in an overlapping state with respect to each of the first rail segment and the second rail segment; engaging a first end portion of the first rail segment by using a first arrangement and actuating the first arrangement to urge the first end portion towards the elongated rigid member; and engaging a second end portion of the second rail segment by using a second arrangement and actuating the second arrangement to urge the second end portion towards the elongated rigid member. When each of the first end portion and the second end portion is urged towards the elongated rigid member, the first rail segment and the second rail segment adjoin and fall in alignment with each other to be connected together and form a contiguous rail portion of a rail line.
Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Generally, corresponding reference numbers may be used throughout the drawings to refer to the same or corresponding parts, e.g., 1, 1′, 1″, 101 and 201 could refer to one or more comparable components used in the same and/or different depicted embodiments.

As part of an exemplary installation procedure of the rail line 108 at the worksite 100, multiple supports 120 and multiple rail segments 116 may be provided, as shown. Although not limited, the supports 120 may include posts 128 (e.g., vertical posts). The posts 128 may define ends (referred to as a post ends 132) (only few marked) and may be made to stand upright relative to the ground surface 124 such that the post ends 132 may be raised above and away from the ground surface 124. Also, the posts 128 may be arranged serially along a path (e.g., a predefined path) on the ground surface 124 along which the rail line 108 is to be laid. To form the rail line 108, multiple rail segments 116 may be serially mounted and arranged atop the post ends 132 such that when the rail segments 116 are joined or connected one after the other, they can cumulatively form the rail line 108. Owing to the placement of the rail segments 116 on the post ends 132 of the posts 128, the rail line 108 may be elevated (e.g., by elevation, E) with respect to the ground surface 124 of the worksite 100.

As an example, in the overlapping state and during the alignment process, the elongated rigid member 158 may overlap the first end portion 136′ and the second end portion 136″ of the first rail segment 116′ and the second rail segment 116″, respectively (e.g., see
The elongated rigid member 158 may include a linear profile, although, in some cases, the elongated rigid member 158 may define one or more curvatures. Such curvatures may depend upon a profile of the first end portion 136′ and the second end portion 136″ of the first rail segment 116′ and the second rail segment 116″, respectively. As an example, the first part 174 and the second part 182 of the elongated rigid member 158 may respectively follow a profile of the first rail segment 116′ and the second rail segment 116″ so as to be compliant with them in the overlapping state and so as to also aid in the alignment of the first rail segment 116′ with the second rail segment 116″ (details related to the alignment process are described later in the present disclosure). In some embodiments, it is possible that the elongated rigid member 158 is long enough to be in an overlapping state with more than two rail segments 116 so as to align each of those rail segments 116 with one another.
The first arrangement 162 and the second arrangement 166 shall now be discussed. The first arrangement 162 is configured to engage the first end portion 136′ of the first rail segment 116′ and be actuated to urge the first end portion 136′ towards the elongated rigid member 158. Similarly, the second arrangement 166 is configured to engage the second end portion 136″ of the second rail segment 116″ and be actuated to urge the second end portion 136″ towards the elongated rigid member 158. When each of the first end portion 136′ and the second end portion 136″ is urged towards the elongated rigid member 158, the first rail segment 116′ and the second rail segment 116″ (or their end portions 136′, 136′) adjoin and fall in alignment with each other to be connected together and form a contiguous rail portion of the rail line 108.
In some embodiments, the first end portion 136′ and the second end portion 136″ may be urged towards the elongated rigid member 158 to either be abutted to the elongated rigid member 158 or define a clearance (e.g., a common consistent clearance) with respect to the elongated rigid member 158.
Each of the first arrangement 162 and the second arrangement 166 may include one or more clasping mechanisms 198—as an example, each of the first arrangement 162 and the second arrangement 166 includes multiple clasping mechanisms 198. However, details corresponding to only a single clasping mechanism (i.e., clasping mechanism 198′) (see

The block 214 may be integral with the clasping edge 218 and may define a through hole 222 defining a hole axis 226. Further, the block 214 may define an outer side wall 230 (also see
The shifting system 206 facilitates a movement of the foot peg 202 to actuate the first arrangement 162 or the second arrangement 166. The shifting system 206 includes a spacer 254 and a fastener 258.
The spacer 254 may be coupled (e.g., fixedly coupled) (e.g., by welding) to the elongated rigid member 158 (e.g., to one of the lateral sides 170 of the elongated rigid member 158). As an example, the spacer 254 may define a cylindrical shape which in turn defines a spacer axis 262, although shapes and profiles other than a cylinder may be contemplated. Also, the spacer 254 may be positioned orthogonally relative to the length, L, of the elongated rigid member 158. The spacer 254 may also define a first spacer axial end 266 and a second spacer axial end 270 opposite to the first spacer axial end 266. The spacer 254 may define a through-bore 274 around the spacer axis 262, and the through-bore 274 may extend from the first spacer axial end 266 to the second spacer axial end 270. According to an aspect of the present disclosure, the through-bore 274 may define a smooth internal peripheral surface 278 with no threads.
The fastener 258 may be received into the through-bore 274 to pass through the through-bore 274. The fastener 258 may be freely rotatable with respect to the through-bore 274. The fastener 258 may define a head 280, a shank 282 extending from the head 280, and a longitudinal axis 286 which may pass through both the head 280 and the shank 282. As an example, the shank 282 may define a threaded portion 290 and a non-threaded portion 294. The non-threaded portion 294 may extend from the head 280 up to the threaded portion 290 and the threaded portion 290 may extend from the non-threaded portion 294 all the way to an end (e.g., a shank end 298) of the shank 282. In an assembly of the fastener 258 to the spacer 254, the head 280 of the fastener 258 may abut or be in contact with the first spacer axial end 266 and one portion (e.g., non-threaded portion 294) of the shank 282 may be accommodated within the through-bore 274, while the other portion (e.g., threaded portion 290) may be disposed outside the through-bore 274, such that the shank end 298 may be disposed away from the second spacer axial end 270. Also, in assembly of the fastener 258 with the spacer 254, the longitudinal axis 286 may be aligned with the spacer axis 262.
Further, the shank 282 of the fastener 258 may be received into the through hole 222 of the foot peg 202 and the threaded portion 290 of the shank 282, disposed outside of the second spacer axial end 270, may be threadably coupled with the internal threads 234 formed in the through hole 222 of the foot peg 202. Effectively, the fastener 258 may be threadably coupled to the foot peg 202, and the foot peg 202 may be angularly rotatable about the longitudinal axis 286 of the fastener 258. When the fastener 258 is rotated with respect to the foot peg 202, the head 280 of the fastener 258 may abut against the spacer 254 (i.e., the first spacer axial end 266 of the spacer 254) and the foot peg 202 may move towards the spacer 254 and thus the elongated rigid member 158. Because the foot peg 202 may be clasped with the first end portion 136′ or the second end portion 136″, during the alignment process, a movement of the foot peg 202 may urge and cause the first end portion 136′ of the first rail segment 116′ or the second end portion 136″ of the second rail segment 116″ to move towards the elongated rigid member 158.
The stopper 210 may be fixedly coupled to the elongated rigid member 158. In other words, the stopper 210 may be immovably coupled with respect to the elongated rigid member 158. The stopper 210 may selectively abut with the first surface 238 and the second surface 242 to restrict a rotation of the foot peg 202 about the longitudinal axis 286 (or the spacer axis 262) within an angular threshold range, AR (see through the cutout provided in
According to some embodiments, when the foot peg 202 is at one angular limit of the angular threshold range, AR, the stopper 210 may be abutted with the first surface 238 and the foot peg 202 may be at a first condition (see clasping mechanism 198′,
Given that there may be multiple clasping mechanisms (such as the clasping mechanism 198′) as part of each of the first arrangement 162 and the second arrangement 166, the clasping mechanisms 198 of the first arrangement 162 may be arranged on the first part 174 and the clasping mechanisms 198 of the second arrangement 166 may be arranged on the second part 182. Moreover, the clasping mechanisms 198 of the first arrangement 162 may be arranged on opposing lateral sides 170 of the first part 174 of the elongated rigid member 158 and the clasping mechanisms 198 of the second arrangement 166 may be arranged on opposing lateral sides 170 of the second part 182 of the elongated rigid member 158.

Once the elongated rigid member 158 is positioned in the overlapping state with respect to each of the first rail segment 116′ and the second rail segment 116″, the operator may turn the foot pegs 202 of each of the clasping mechanisms 198 of the first arrangement 162 and the second arrangement 166 into the first condition (see foot pegs 202 in
According to an embodiment, a method by which the foot pegs 202 may be turned to clasp the first end portion 136′ and the second end portion 136″ may include sequentially activating the clasping mechanisms 198 (including turning the corresponding foot pegs 202 from the second condition to the first condition) of the first arrangement 162 arranged on the first part from the first end 178 towards the interface 190. In so doing, the first arrangement 162 is actuated to urge the first rail segment 116′ towards the elongated rigid member 158. The method may also include sequentially activating the clasping mechanisms 198 (including turning the corresponding foot pegs 202 from the second condition to the first condition) of the second arrangement 166 arranged on the second part 182 from the second end 186 towards the interface 190. In that manner, the second arrangement 166 is also actuated to urge the second rail segment 116″ towards the elongated rigid member 158.
Once the foot pegs 202 are turned to the first condition to engage the first end portion 136′ and the second end portion 136″, and as part of the actuation of the first arrangement 162 and the second arrangement 166, the operator may turn (e.g., in a clockwise manner) (e.g., sequentially from the first end 178 towards the interface 190) the fasteners 258 of the clasping mechanisms 198 of the first arrangement 162 such that the first end portion 136′ may be urged towards the elongated rigid member 158. The operator may also turn (e.g., in a clockwise manner) (e.g., sequentially from the second end 186 towards the interface 190) the fasteners 258 of the clasping mechanisms 198 of the second arrangement 166 such that the second end portion 136″ may also be urged towards the elongated rigid member 158. In some embodiments, a turning induced to the fasteners 258 may cause the corresponding foot pegs 202 to also rotate and move (e.g., automatically rotate and move owing to the threadable connection of the foot pegs 202 with the fasteners 258) to the first condition (e.g., see
The fasteners 258 of the clasping mechanisms 198 of both the first arrangement 162 and the second arrangement 166 may be turned until the first end portion 136′ and the second end portion 136″ are raised and either are abutted to the elongated rigid member 158 or define respective clearances, C1 and C2, with respect to the elongated rigid member 158 which may become equal to each other. The abutment or the equal clearances ensure that the first end portion 136′ (or the first rail segment 116′) has fallen in alignment with the second end portion 136″ (or the second rail segment 116″). At this point, the foot pegs 202 may be tightly clasped with the first end portion 136′ and the second end portion 136″. When the clearances, C1 and C2, become equal to each other, said clearances, C1 and C2, may correspond to a common consistent clearance defined by the elongated rigid member 158 with the first part 174 and the second part 182 throughout the length of the first part 174 and the second part 182.
In that manner, once the first end portion 136′ (and/or the first rail segment 116′) and the second end portion 136″ (and/or the second rail segment 116″) are aligned, the operator may use a connection plate (not shown) to connect the first end portion 136′ with the second end portion 136″—e.g., the connection plate may be positioned in part over the first end portion 136′ and in part over the second end portion 136″, and then one or more fastening elements (not shown) may be driven into the connection plate and the assemblage of the first end portion 136′ and the second end portion 136″ such that the connection plate can be connected (e.g., immovably connected) to each of the first end portion 136′ and the second end portion 136″, in turn connecting (e.g., rigidly connecting and reinforcing) the first rail segment 116′ with the second rail segment 116″ and thus forming a rail portion of the rail line 108.
After the connection is complete, the operator may turn the fasteners 258 of the clasping mechanisms 198 of the first arrangement 162 and the second arrangement 166 in reverse (e.g., in a counter clockwise direction) to loosen the foot pegs 202. Once the foot pegs 202 are loosened by the turning of the fasteners 258, each foot peg 202 may be moved to the second condition (see
It may be understandable from the above description that the tool 150 provides for an easy, inexpensive, and a reliable solution, to align the first rail segment 116′ with the second rail segment 116″ of the rail line 108, and the same may be performable by operators with basic or minimum skill. Also, the tool 150 may be applicable at various worksites that include a rail line. Moreover, the tool 150 is easy to use and is relatively compact for transportation and handling. Furthermore, the tool 150 is simple in construction and requires no parts which are complex or cumbersome to manufacture and/or assemble.
