[0020] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] This embodiment provides a roller block for railway resetting, such as Figure 1 and Figure 2 As shown, it includes a main body 4, a roller assembly, a pad assembly and a handle assembly. The lower part of the main body 4 is provided with a plurality of roller assemblies. The pad assembly includes a detachably connected pad 1 and a self-lubricating pad 5. The self-lubricating pad 5 is arranged on the upper surface of the main body 4. The pad 1 is arranged on the self-lubricating pad 5. The pad 1 is used to place the lifting mechanism. The self-lubricating pad 5 has an anti-wear effect and can improve the overall service life of the roller block. In order to adapt to low-chassis vehicles and facilitate entry under the car compartment, the height of the main body 4 of this embodiment is designed to be relatively low. Since the lifting height of the lifting mechanism is certain, and the height of the main body 4 is relatively low, the pad 1 can be set to different height specifications to match chassis vehicles of different heights. The pad 1 can compensate for the displacement of the lifting mechanism to a certain extent. At the same time, the pad 1 is detachably connected to the self-lubricating pad 5, which is convenient for replacing the damaged pad 1. The handle assembly includes a clamping column 3, which is arranged below the main body 4 and is positioned at the front and rear outer sides of the guide rail. When this embodiment is used, the guide rails are vertically placed on two parallel railway tracks, and the clamping column 3 positions the roller block on the guide rails. Due to the action of the clamping column 3, the roller block can move left and right along the guide rails under the action of the push-pull mechanism.

[0022] Specifically, the main body 4 is in a rectangular parallelepiped shape, and the left and right sides of the front side and the rear side of the main body 4 are respectively provided with connecting parts 10 extending outward, and the connecting parts 10 are provided with the clamping column 3 protruding downward, and the lower end of the clamping column 3 is lower than the roller assembly. The clamping column 3 is symmetrically arranged, and the guiding effect on the roller block is uniform.

[0023] Furthermore, the front-to-rear spacing of the clamping column 3 is adapted to the width of the guide rail, which facilitates the movement of the roller trolley along the guide rail and facilitates push-pull resetting.

[0024] Specifically, the handle assembly further includes handles 11, which are respectively arranged at the front and rear sides of the main body 4. The height of the handles 11 is flush with or lower than the upper surface of the main body 4, so as to prevent the handles 11 from being too high and affecting the roller block from entering the lower part of the carriage. The handles 11 facilitate lifting the roller block.

[0025] Specifically, the left and right sides of the main body 4 are respectively provided with lifting ears 12, and the lifting ears 12 are used to connect with the push-pull mechanisms on the left and right sides.

[0026] In this embodiment, the lifting mechanism and the push-pull mechanism respectively use oil cylinders. In other embodiments, the lifting mechanism and the push-pull mechanism can also be existing linear modules, gear racks or cylinders, etc. This application does not make specific restrictions on the lifting mechanism and the push-pull mechanism.

[0027] Furthermore, one of the pad 1 and the self-lubricating pad 5 is provided with a U-shaped slot, and the other is provided with a block connected to the U-shaped slot. The pad 1 and the self-lubricating pad 5 are detachably connected through the U-shaped slot, and the connection is simple and convenient for disassembly and assembly. The pad 1 and the self-lubricating pad 5 can also be detachably connected by pin connection, screw connection, etc. In this embodiment, the U-shaped slot is set in the front-to-back direction to prevent the left-right movement of the roller block from affecting the connection between the pad 1 and the self-lubricating pad 5.

[0028] Specifically, the roller assembly includes a shaft 2, a bushing 6, a self-lubricating anti-wear pad 7, a roller 9 and a spring retaining ring 8. The front and rear sides of the main body 4 are respectively provided with a plurality of shaft holes, and the two ends of the shaft 2 extend out of the shaft holes respectively. The shaft 2 is provided with the bushing 6, and the roller 9 is provided outside the bushing 6. The spring retaining ring 8 is provided at both ends of the shaft 2, and the self-lubricating anti-wear pad 7 is provided at both ends of the roller 9. The present application does not specifically limit the number of rollers 9. For example, in the present embodiment, four rollers 9 are respectively provided at the front and rear of the main body 4, and the two ends of each roller 9 are respectively provided with a self-lubricating anti-wear pad 7 to ensure smooth rolling of the roller 9.

[0029] The working process of this embodiment is as follows: the guide posts of the handle assembly are placed on the front and rear sides of the guide rail, so as to position the roller block on the guide rail, and the push-pull mechanisms on the left and right sides of the guide rail are respectively connected to the left and right lifting ears 12 of the roller block body 4, and the roller block is pulled to move left and right on the guide rail; the self-lubricating pad 5 is connected to the body 4, and then the pad 1 is placed on the self-lubricating pad 5 through the U-shaped slot. This structure can compensate for the displacement of the lifting mechanism on the roller block; a lifting mechanism is placed on the roller block, and the lifting mechanism can lift one end of the dislocated carriage, and drive the roller block to move left and right on the guide rail through the left and right push-pull mechanisms, thereby realizing the restoration of the carriage.

[0030] This embodiment adopts a main body with a lower height to adapt to low-chassis vehicles. The pad on the main body is detachably connected. By matching pads of different heights, the jacking mechanism on the roller pulley can be compensated for displacement. It can be applicable to vehicles with chassis of different heights and has high versatility. The pad is detachable, which is convenient for replacing the pad. The clamping column can be effectively positioned on the front and rear sides of the guide rail, and has a guiding effect on the left and right movement of the roller pulley. When resetting, the roller rolls on the guide rail, which is efficient and time-saving, and improves work efficiency.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
