[0027] In this embodiment, strong magnet sheets 10 are provided inside the positioning hole 17 in the docking groove 6 and at the end of the positioning pin shaft 7. The sizes of the strong magnet sheets 10 match each other. Through the provision of the strong magnet sheets 10, the positioning pin shaft 7 can be firmly inserted into the positioning hole 17 and is not easy to fall off during use.

[0028] In this embodiment, the other end of the positioning pin shaft 7 is fixedly connected to a rectangular block 8, and the front of the rectangular block 8 is fixedly connected to a pull-out handle 9. The pull-out handle 9 is provided to facilitate people to hold and pull out the positioning pin shaft 7.

[0029] In this embodiment, a support base 12 is provided at the bottom of the beam body 1, and the bottom area of ​​the support base 12 is larger than the top thereof. By providing an irregular support base 12, the contact area between the bottom of the support base 12 and the ground is increased, thereby providing better stability when placed, so that the brake beam is not easy to overturn when people inspect and repair the brake beam.

[0030] In this embodiment, an anti-skid pad 13 is bonded to the bottom of the support base 12 , and an anti-skid pattern is provided on the surface of the anti-skid pad 13 . The placement stability of the support base 12 is further increased by the provision of the anti-skid pad 13 . Example

[0031] On the basis of the first embodiment, the preferred embodiment of the reinforced brake beam provided by the present invention is as follows: Figures 1 to 5 As shown:

[0032] In this embodiment, a storage groove is provided at the bottom of the support base 12 near the edge, and a damping shaft 14 is provided on the inner wall of the storage groove. A flip block 15 is fixedly connected to the end of the damping shaft 14, and a fixing cone 16 is fixedly connected to the front of the flip block 15. The fixing cone 16 is provided and the flip block 15 is driven by the damping shaft 14 to rotate and rotate out for use. When the ground is uneven, it is convenient for people to insert it into the soil next to the railway, thereby achieving the fixation of the support base 12 and making it more convenient for people to inspect and repair the brake beam.

[0033] In this embodiment, a rotating shaft 11 is arranged at the top center of the supporting base 12, and the top of the rotating shaft 11 is connected to the bottom of the beam body 1. The beam body 1 and the supporting base 12 form a rotatable structure through the rotating shaft 11. The brake beam can be rotated to adjust the angle through the arranged rotating shaft 11. When inspecting the brake beam, people do not need to walk back and forth to observe. They only need to rotate the brake beam in place to conduct a comprehensive inspection and maintenance of the brake beam.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] When the brake beam is used for a period of time, it is removed from the train for inspection and repair. In the case of flat ground, the support base 12 is placed on the ground, and the anti-skid pad 13 at the bottom can play a good supporting effect. The brake beam is rotated during inspection and repair, and the brake beam is rotated by the rotating shaft 11. Therefore, people do not need to walk back and forth to observe when inspecting the brake beam. They only need to rotate the brake beam in place to perform a comprehensive inspection and maintenance of the brake beam. If the inspection and repair work is carried out next to the railway, it is not easy to place due to the uneven ground. At this time, the fixing cone 16 is driven by the damping shaft 14 to rotate and screw out the flip block 15 for use, and inserted into the soil next to the railway, thereby achieving the fixation of the support base 12, and then the inspection and repair work can be carried out.

[0036] In summary, with the aid of the above-mentioned technical scheme of the utility model, the docking block 501 is set, inserted into the docking groove 6 on the connecting block 4, and the positioning pin shaft 7 is inserted into the positioning hole 17. The docking is adsorbed by the strong magnet sheet 10, and the installation is convenient. When disassembling, you only need to hold the pull-out handle 9 to pull out the positioning pin shaft 7, which simplifies the disassembly and assembly steps of the brake shoe assembly 5 and makes it more convenient for people to quickly replace the brake shoe assembly 5. The special-shaped support base 12, together with the anti-slip pad 13 and the fixed cone 16 at the bottom, is convenient for people to place and repair the disassembled brake beam on flat or uneven ground. The setting of the rotating shaft 11 enables the brake beam to be rotated for angle adjustment. People do not need to walk back and forth to observe when inspecting the brake beam. They only need to rotate the brake beam in situ to conduct a comprehensive inspection and maintenance of the brake beam.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. 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.
