[0026] Working principle: When the utility model is used for distance measurement and collision prevention of construction machinery, during the use of the transport vehicle, a pneumatic failure occurs in the vehicle blocking device, the transport vehicle bucket 3 slips, and the roller 5 cannot stop rotating on the conveying track 2. When the transport vehicle bucket 3 carried by the roller 5 moves to the predetermined braking distance, the transport vehicle bucket 3 drives the safety plate 4 to move and collide with the triangular three-dimensional traction block 9. The movement of the triangular three-dimensional traction block 9 drives the traction rack 23 to move. After the traction rack 23 moves, it drives the moving block 24 to slide smoothly on the guide rod 19. When the traction rack 23 moves, it can drive the linkage gear 27 meshing with it to rotate. After the linkage gear 27 rotates, it can drive the rotating column 26 to rotate. After the rotating column 26 rotates, it drives the rotating disk 13 to rotate.

After the embedded slide 15 moves, it also drives the restraining clamp block 6 to move. After the restraining clamp block 6 moves, it drives the linkage block 8 to move. When the linkage block 8 moves, it drives the embedded slide 15 to return to a straight line. When the transport bucket 3 moves to a certain After the roller 5 is in the position, it enters the slot 20 provided in the restraining clamp block 6 and conflicts with the anti-skid leather pad 25 provided in the slot 20. As the roller 5 rolls, the restraining clamp block 6 slides on the conveying track 2, and then drives the linkage block 8 to move so that the anti-car brake rod 7 moves to one end. Then, the limiting groove 35 provided in the restraining clamp block 6 slides along the embedded slide plate 15. At the same time, when the anti-car brake rod 7 moves, it drives the baffle plate 30 to move in the limit box 14 and compress the long spring 29 to block in turn. Then, under the action of force, the anti-car brake rod 7 drives the connecting block 34 to move. After the connecting block 34 moves, it drives the two movable rods 33 to unfold respectively. After the movable rod 33 is unfolded, it pushes The two sleeve blocks 31 move away from each other on the reinforcing rod 32, and act against the strong spring 21, thereby blocking it again. After the transport bucket 3 reaches the slot 20, the tail may flip up due to inertia. However, under the limit of the slot 20, the force acting on the restraining clamp block 6 begins to act on the outer surface and the bottom of the conveying track 2, and the transport bucket 3 can be prevented from tipping over under the condition of embedded sliding. When the restraining clamp block 6 moves, it drives the fixed rod 10 to move. After the fixed rod 10 moves, it drives the protective block 11 to slide on the outer surface of the conveying track 2, thereby enhancing the limiting effect of anti-collision and anti-rollover, thereby achieving a solution to the problem of the vehicle blocking device during railway transportation.
