[0020] The following description is only a preferred embodiment of the utility model, and the protection scope is not limited to the embodiment only. Any technical solution falling within the concept of the utility model should be within the protection scope of the utility model. It should be noted that, for ordinary technical personnel in the technical field, some improvements and refinements without departing from the principle of the utility model should also be considered as the protection scope of the utility model.

[0021] As shown in the figure, a tram brake mounting bolt structure comprises a brake base 1.

[0022] The brake base 1 is provided with a buffer structure, which comprises a buffer slope 2, a positioning groove 3, a positioning bolt 4, a connecting block 5, and a buffer baffle 6. The buffer baffle 6 is connected to the ground, the connecting block 5 connects the two buffer slopes 2, the buffer slope 2 is in the shape of an inverted U, the positioning groove 3 is vertically arranged on the side of the buffer slope 2 away from the connecting block 5, and the positioning bolt 4 is connected to the ground through the positioning groove 3. The connecting block 5 is in the shape of a U, and the connecting block 5 connects the two buffer slopes 2, so that the connecting block 5 and the buffer slope 2 as a whole are in the shape of an m. The positioning bolt 4 is screwed through the moving spacer 8 and the positioning groove 3 to install the brake base 1 on the ground. The wheels of the tram stop on the surface of the connecting block 5 after passing through the buffer slope 2.

[0023] The horizontal sliding groove 7 is arranged in the buffer slope 2, and the sliding groove 7 is connected with the positioning groove 3, the movable gasket 8 is slidably connected in the sliding groove 7, and the positioning bolt 4 penetrates through the movable gasket 8. The deceleration convex is fixedly connected to the side, away from the buffer baffle 6, of the buffer slope 2. After the wheel contacts the buffer slope 2, the buffer main body is driven to impact the surface of the reset plate 11 and compress the spring 10. During resetting, the spring 10 drives the brake base 1 to reset, so that the buffer space is reserved for the fixed bolt during the buffer process, and the service life is prolonged.

[0024] The reset groove 9 is arranged at the bottom of the buffer baffle 6, and the reset plate 11 is connected to the bottom of the reset groove 9 through the spring 10. The blocking groove 12 is fixedly connected to the top of the buffer baffle 6 and is curved.

[0025] Working principle: The positioning bolt 4 penetrates through the movable gasket 8 and the positioning groove 3, and the brake base 1 is installed on the ground. After the wheel bottom of the tram passes through the buffer slope 2, the wheel is stopped on the surface of the connecting block 5. After the wheel contacts the buffer slope 2, the buffer main body is driven to impact the surface of the reset plate 11 and compress the spring 10. During resetting, the spring 10 drives the brake base 1 to reset, so that the buffer space is reserved for the fixed bolt during the buffer process, and the service life is prolonged.

[0026] In summary, through the ups and downs of the two buffer slopes 2 and the connecting block 5, the tire of the tram is decelerated, and the brake base 1 is driven to move backward, the brake base 1 is moved along the positioning groove 3 from one end to the other end, the buffer distance is improved, and the service life of the positioning bolt 4 is improved.
