Description

Technical Field

[0001] This application relates to the field of railway auxiliary equipment technology, and in particular to a rerailing device. Background Technology

[0002] As one of the main modes of transportation across regions, railway transportation holds an irreplaceable and important position in the global freight and passenger transport market. However, when trains travel at high speeds on rails, derailments occasionally occur. Therefore, rerailing devices are required to put trains back on track during rerailing operations.

[0003] Currently, when railway rerailing devices are placed on railway tracks, they lack secure fixed support points. During rerailing operations, the rerailing devices may shift, affecting the normal progress of the rerailing work and causing secondary derailment. Utility Model Content

[0004] Therefore, it is necessary to provide a rerailing device to address the problem that the current railway rerailing devices have poor stability and are prone to secondary derailment.

[0005] A rerailing device, comprising a base and a positioning seat, wherein:

[0006] The base includes a base plate and two guide protrusions spaced apart on the base plate. The base plate also has a mounting groove located between the two guide protrusions, and the mounting groove communicates with the first end of the base plate.

[0007] The positioning seat includes a first pad and a second pad spaced apart at the first end. The first pad and the second pad are both located on the side of the guide protrusion near the bottom plate. The first pad and the second pad have a first side and a second side facing away from the guide protrusion, respectively. The first side and the second side abut against the sleeper. The first side is also provided with a first positioning component for clamping the side wall of the sleeper.

[0008] In one embodiment, the first positioning component includes a first positioning member and a second positioning member spaced apart along a first direction, the first positioning member and the second positioning member abutting against two side walls of the sleeper that are directly opposite each other along the first direction.

[0009] In one embodiment, the first positioning component further includes a third positioning member disposed on the first side, the third positioning member abutting against a side wall of the sleeper that is perpendicular to a second direction, the second direction being perpendicular to the first direction.

[0010] In one embodiment, the first side is provided with a first mounting hole and a second mounting hole, the first positioning member is movably disposed in the first mounting hole along the first direction, and the third positioning member is movably disposed in the second mounting hole along the second direction.

[0011] In one embodiment, the second positioning member includes a support frame and an abutment block disposed on the support frame. The support frame is disposed on the side of the base plate opposite to the guide protrusion, and the abutment block abuts against the side wall of the sleeper.

[0012] In one embodiment, the support frame includes a first plate and a second plate connected at a preset angle, the first plate being disposed on the base plate and the second plate being connected to the abutment block.

[0013] In one embodiment, the second side is further provided with a second positioning component, the second positioning component including a fourth positioning member disposed on the side of the base plate opposite to the guide protrusion, the fourth positioning member and the second positioning member being arranged at intervals along a second direction, the fourth positioning member and the second positioning member abutting against the same side of the sleeper.

[0014] In one embodiment, the second positioning component further includes a plurality of support blocks, which are spaced apart at the outer edge of the second pad away from the first pad.

[0015] In one embodiment, the rerailer further includes at least one handle disposed on the side wall of the base plate.

[0016] In one embodiment, both the first pad and the second pad are detachably connected to the base plate.

[0017] The aforementioned rerailing device, by having mounting grooves on its base plate, facilitates its positioning on the rail. The spaced guide protrusions on the base plate allow the derailment-preventing rollers to return to their original position along the space between the two protrusions. Furthermore, the base plate, with its first and second pads abutting against the sleepers on the side opposite to the guide protrusions, and the first pad also having a first positioning component for clamping the sidewall of the sleeper, ensures the rerailing device is stably fixed to the sleepers, preventing displacement during use and thus avoiding secondary derailment of the rollers.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] See Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the re-tracking device 10 in one embodiment of this application is shown. Figure 2This diagram shows a structural schematic of the rerailer 10 from another perspective in one embodiment of this application. The rerailer 10 provided in one embodiment of this application is applied to a railway track. The railway track has rails, and the bottom end of the rails is laid with a number of spaced sleepers along its length. The train's rollers are used to move on the rails. When the rollers detach from the rails, the rerailer 10 is required to reset the rollers.

[0033] The rerailing device 10 includes a base 100 and a positioning seat 200. The base 100 includes a bottom plate 110 and two guide protrusions 120 spaced apart on one side of the bottom plate 110. In a specific configuration, the two guide protrusions 120 are arranged in a "V" shape. The space between the two guide protrusions 120 is used to guide the return position of the limiting roller. The bottom plate 110 also has an installation groove 111 located between the two guide protrusions 120. The installation groove 111 is connected to the first end 112 of the bottom plate 110 and is used to clamp the rail.

[0034] The positioning seat 200 includes a first pad 210 and a second pad 220 spaced apart at the first end 112. In a specific configuration, the first pad 210 and the second pad 220 form an accommodating space 230 that communicates with the mounting groove 111, so as to avoid the first pad 210 and the second pad 220 affecting the fit between the mounting groove 111 and the rail. Specifically, the first pad 210 and the second pad 220 are symmetrically arranged about the mounting groove 111.

[0035] Both the first pad 210 and the second pad 220 are located on the side of the guide protrusion 120 near the bottom plate 110. The first pad 210 and the second pad 220 have a first side 211 and a second side 221 facing away from the guide protrusion 120, respectively. The first side 211 and the second side 221 abut against the upper surface of the sleeper, that is, the side of the sleeper near the rail. The first side 211 is also provided with a first positioning component 240 for clamping the side wall of the sleeper.

[0036] The aforementioned rerailing device 10, by having an installation groove 111 on the base plate 110, facilitates the positioning of the rerailing device 10 on the rail through the installation groove 111; by providing spaced guide protrusions 120 on the base plate 110, it facilitates the return of the derailed roller along the space between the two guide protrusions 120; by providing a first pad 210 and a second pad 220 on the side of the base plate 110 opposite to the guide protrusions 120, which abut against the sleeper, and the first pad 210 is also provided with a first positioning component 240 for clamping the side wall of the sleeper, the rerailing device 10 can be stably fixed on the sleeper, preventing displacement of the rerailing device 10 during use, thereby preventing secondary derailment of the roller. Furthermore, the rerailing device 10 of this application has a simple overall structure, is easy to operate, and can effectively save costs and improve work efficiency.

[0037] In specific configuration, in order to facilitate the guide rollers of the first pad 210 or the second pad 220 to travel on the rerailer 10, the side of the first pad 210 and the second pad 220 near the guide protrusion 120 are both set as arc-shaped curved surface structures.

[0038] Combination Figure 3 As shown, Figure 3 for Figure 2 A magnified schematic diagram of the structure at point A. To facilitate the clamping of the sidewalls of the sleeper by the first positioning component 240, in a preferred embodiment, the first positioning component 240 includes a first positioning member 241 and a second positioning member 242 spaced apart along a first direction a. The first positioning member 241 and the second positioning member 242 abut against the two opposite sidewalls of the sleeper along the first direction a. That is, the first positioning member 241 and the second positioning member 242 abut against the front and rear sidewalls of the sleeper, forming a first space between them along the first direction a to clamp the sleeper, thereby achieving the effect of clamping the sleeper.

[0039] To further secure the rerailer 10 to the sleeper, the first positioning assembly 240 further includes a third positioning member 243 disposed on the first side 211. The third positioning member 243 abuts against a side wall of the sleeper perpendicular to the second direction b, which is perpendicular to the first direction a. Through this arrangement, the first positioning member 241, the second positioning member 242, and the third positioning member 243 of the first positioning assembly 240 abut against three adjacent side walls of the sleeper, thereby surrounding the sleeper and securing the rerailer 10 to the sleeper, preventing displacement of the rerailer 10.

[0040] To enable the rerailer 10 to adapt to various types of sleepers, more specifically, the first side 211 is provided with a first mounting hole 212 and a second mounting hole 213; a first positioning member 241 is movably disposed in the first mounting hole 212 along a first direction a, and a third positioning member 243 is movably disposed in the second mounting hole 213 along a second direction b. Through the above arrangement, the first positioning member 241 and the third positioning member 243 can move to a certain extent along the first direction a and the second direction b respectively, allowing the first positioning assembly 240 to adapt to sleepers of different sizes and be applied to sleepers of various sizes, thus having better applicability and eliminating the need to manufacture multiple sizes of rerailer 10 for different sizes of sleepers.

[0041] To facilitate the first positioning member 241 being movable along the first direction a in the first mounting hole 212, a partial cavity is formed inside the first pad 210, and the first mounting hole 212 is connected to the cavity. The first mounting hole 212 is preferably an oblong hole whose length extends along the first direction a. The first mounting member includes a first bolt 2411 and a first nut 2412. The head of the first bolt 2411 is located in the cavity, and the screw portion of the first bolt 2411 passes through the first mounting hole 212 and is adapted to the first nut 2412.

[0042] Similarly, to facilitate the movability of the third positioning element 243 within the second mounting hole 213 along the second direction b, the second mounting hole 213 is specifically designed to communicate with the cavity. The second mounting hole 213 is preferably an oblong hole extending along the second direction b. The third mounting element includes a second bolt 2431 and a second nut 2432. The head of the second bolt 2431 is located within the cavity, and the threaded portion of the second bolt 2431 passes through the second mounting hole 213 and is fitted with the second nut 2432. Through this design, both the first positioning element 241 and the third positioning element 243 utilize common structural components, eliminating the need for additional fabrication, thus reducing manufacturing costs and making replacement very convenient.

[0043] To facilitate the design of the second positioning element 242, specifically, the second positioning element 242 includes a support frame 2421 and an abutment block 2422 disposed on the support frame 2421. The support frame 2421 is disposed on the side of the base plate 110 opposite to the guide protrusion 120, and the abutment block 2422 abuts against a side wall extending along the second direction b in the sleeper. It should be noted that the first positioning element 241 can move along the first direction a to adjust the distance between it and the second positioning element 242, and the second positioning element 242 does not need to be made movable.

[0044] To provide stable support for the abutment block 2422, the support frame 2421 includes a first plate and a second plate connected at a preset angle. The first plate is disposed on the base plate 110, and the second plate is connected to the abutment block 2422. In a specific configuration, the first plate and the second plate are connected at a 90° angle, but not limited to this 90° angle. When the first plate and the second plate are connected at a 90° angle, the second plate provides a flat mounting position for the abutment block 2422. The abutment block 2422 can be made using common structural components, such as nuts, which are readily available and inexpensive.

[0045] See again Figure 2In order to strengthen the connection between the rerailer 10 and the sleeper, in a preferred embodiment, the second side 221 is also provided with a second positioning component 250. The second positioning component 250 includes a fourth positioning member 251 disposed on the side of the base plate 110 away from the guide protrusion 120. The fourth positioning member 251 and the second positioning member 242 are arranged at intervals along the second direction b, and the fourth positioning member 251 and the second positioning member 242 abut against the same side of the sleeper.

[0046] It should be noted that during the rerailing process, the rollers travel onto the rerailer 10 from the side where the second pad 220 is located. The second pad 220 will bear a large pressure. In order to share the pressure of the second pad 220 and maintain the stability of the rerailer 10, the second positioning component 250 also includes multiple bearing blocks 252. The multiple bearing blocks 252 are spaced apart on the outer edge of the second pad 220 away from the first pad 210. In the specific configuration, the number of bearing blocks 252 can be two, three or more. That is, the bearing blocks 252 are set at the connection between the second pad 220 and the base 100, so that the pressure on the second pad can be transmitted to the base 100.

[0047] In order to facilitate the transportation of the rerailer 10, in a preferred embodiment, the rerailer 10 further includes at least one handle 300, which is disposed on the side wall of the base plate 110. In a specific configuration, there are two handles 300, which are disposed at intervals on the two side walls of the base plate 110.

[0048] In order to facilitate timely replacement of damaged first pad 210 and second pad 220, in a preferred embodiment, both first pad 210 and second pad 220 are detachably connected to the base plate 110. Specifically, both first pad 210 and second pad 220 can be connected to the base plate 110 using strong magnets.

[0049] In order to achieve lightweight design while meeting structural strength and service life requirements, the base 100 is made of titanium alloy, and multiple spaced weight-reducing grooves 113 are provided at the bottom end of the base plate 110 in the base 100. Through the above arrangement, while effectively reducing the weight of the base 100, the groove wall of the weight-reducing groove 113 can also play a role similar to a reinforcing rib, preventing the base 100 from deforming under greater pressure.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
