[0002] When the tunnel section is on a downhill slope in the direction of the shaft entrance or the direction of shield tunneling, the tunnel trolley relies solely on its own braking system to maintain its position after stopping. When it is on a downhill slope, the weight of the trolley and the load it carries makes it prone to slippage. Once it slips, it cannot be well controlled and can only stop on its own by colliding with other objects or reaching a flat section of the road. This affects the safety of construction workers inside the tunnel, and collisions can lead to greater economic losses for tunnel construction. Utility Model Content

With the connection between the tunnel surface 1 and the guide rail 11, the guide rail 11 facilitates the movement and operation of the tunnel electric vehicle in the tunnel.
[0025] The stopping mechanism includes a first cement block 2 and a second cement block 24. A first I-beam 21 is fixedly connected to the surface of the first cement block 2, and a support plate 22 is fixedly connected to the surface of the first I-beam 21. A second I-beam 26 is fixedly connected to the surface of the second cement block 24, and a connecting frame 25 is fixedly connected to the surface of the second I-beam 26. A stop beam 23 is movably connected to the surface of the first I-beam 21. A motor 29 is fixedly connected to the surface of the support plate 22. An infrared speed measuring instrument 28 and an audible and visual alarm 27 are installed on the surface of the first I-beam 21. A light strip 281 is electrically connected to the surface of the infrared speed measuring instrument 28. Through the action of the first cement block 2 and the second cement block 24, the stop beam 23 and the connecting frame 25 are supported at their positions. With the connection of the connecting frame 25 and the stop beam 23, the tunnel battery vehicle is blocked from moving along the guide rail 11.
[0026] Furthermore, the first cement pier 2 and the second cement pier 24 are distributed at both ends of the guide rail 11. The support plate 22 is connected to the outside of the first cement pier 2 through the first I-beam 21. The retaining beam 23 and the connecting frame 25 are engaged and connected. Through the connection of the first cement pier 2 and the first I-beam 21, the first I-beam 21 provides support for the angle of action of the retaining beam 23. With the engaging connection of the connecting frame 25 and the retaining beam 23, the buffering and stopping operation of the tunnel battery vehicle is completed.
[0027] Furthermore, the output shaft of the motor 29 is fixedly connected to the stop beam 23. The stop beam 23 is rotatably connected to the first I-beam 21 via the motor 29. The light strip 281 is distributed on the outer surface of the stop beam 23. Through the connection between the support plate 22 and the motor 29, the rotation control effect of the stop beam 23 is achieved under the connection between the output shaft of the motor 29 and the stop beam 23. Under the action of the infrared speed measuring instrument 28 and the audible and visual alarm 27, the effects of speed measurement and audible and visual alarm are achieved. The infrared speed measuring instrument 28 and the audible and visual alarm 27 are existing products, and their principles are existing technologies, so they will not be described in detail here. The function of the light strip 281 is to display the light and shadow of the stop beam 23 so that the position of the stop beam 23 can be clearly seen in a dim environment.
[0028] Furthermore, the surface of the connecting frame 25 is provided with a snap-fit mechanism, which includes a plug rod 3. The plug rod 3 is inserted into the surface of the connecting frame 25. A baffle 31 is movably connected to the inner wall of the connecting frame 25. A fixing block 32 is fixedly connected to the end surface of the baffle beam 23 away from the first I-beam 21. A control block 33 is fixedly connected to the surface of the baffle 31. A rotating rod 34 is fixedly connected to the inner wall of the connecting frame 25. A torsion spring 35 is sleeved on the outer surface of the rotating rod 34. Through the insertion of the connecting frame 25 and the plug rod 3, the stability of the connection of the baffle beam 23 within the connecting frame 25 is improved.
[0029] Furthermore, the insertion rod 3 penetrates one side surface of the connecting frame 25, and the surface of the retaining beam 23 is provided with a through hole. The insertion rod 3 is inserted through the through hole on the connecting frame 25 and the retaining beam 23.

[0030] Furthermore, the cross-section of the baffle 31 is L-shaped. The baffle 31 is elastically rotatably connected to the connecting frame 25 through the rotating rod 34 and the torsion spring 35. Through the connection between the baffle 31 and the rotating rod 34, the baffle 31 can elastically rotate within the connecting frame 25 under the action of the torsion spring 35. Under the action of the baffle 31, the insertion rod 3 can be supported at its position on the connecting frame 25. When the control block 33 and the fixed block 32 abut against each other, the angle of action of the baffle 31 is changed, causing the insertion rod 3 to fall and complete the insertion operation between the insertion rod 3 and the baffle beam 23.
[0031] Working principle: When performing buffering and stopping operation on the tunnel battery car, the motor 29 starts, driving the stop beam 23 to rotate on the first I-beam 21, so that the stop beam 23 and the connecting frame 25 are inserted. Under the connection of the stop beam 23 and the fixing block 32, the fixing block 32 and the control block 33 abut against each other. At this time, the angle of the baffle 31 in the connecting frame 25 changes, and the baffle 31 and the insert rod 3 are released from contact. Under the weight of the insert rod 3, the insert rod 3 and the stop beam 23 are inserted, improving the stability of the connection of the stop beam 23 in the connecting frame 25. Under the action of the stop beam 23, the buffering and stopping effect of the tunnel battery car slipping on the guide rail 11 is achieved, so that it stops moving.
