The left and right ends of the bottom of the brake frame 5 are provided with a first brake block 8, a second embedded block 9 and a third embedded block 10. The first brake block 8, the second embedded block 9 and the third embedded block 10 are all in a concave structure, and a plurality of groups of locking holes 11 are opened on the side of the third embedded block 10. When installing the whole, the staff puts the first brake block 8, the second embedded block 9 and the third embedded block 10 at the bottom of the brake frame 5 of the brake housing assembly 1 into the track, so that the bottoms of the first brake block 8, the second embedded block 9 and the third embedded block 10 will be embedded in the track, and the staff inserts bolts into the locking holes 11 of the third embedded block 10 to further fix the brake main assembly 1 on the track for use.

When the hydraulic buffer 4 is subjected to impact force, the hydraulic buffer 4 consumes the impact force through a certain pressure of nitrogen and a certain amount of hydraulic oil, thereby reducing the impact force and achieving the purpose of blocking the vehicle.
