Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit anti-collision equipment, and in particular relates to a rail transit anti-collision device for transportation engineering. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. During the transportation of rail transit vehicles such as subways and light rails, passengers sometimes need to stand in the cabin. Although there are handrails for them to hold on to to ensure their balance, the inertia of the passengers' bodies when starting and stopping can still easily cause them to collide with the inner wall of the cabin, which can easily cause damage to the passengers' bodies. The existing method is to stick anti-collision pads on the inner wall of the cabin.

[0003] The utility model with authorization announcement number CN216508350U provides a rail transit anti-collision device for transportation engineering. By providing a suction cup, a lever, a rotating shaft and a threaded rod, such a structure not only enables the device to be quickly disassembled and assembled, but also prevents the device from causing difficult-to-clean installation marks on the inner wall of the cabin, thereby reducing the difficulty of cleaning when replacing the device.

[0004] However, in the above patent, the device is fixed to the inner wall of the carriage by suction. After the device has been used for a period of time, air enters the negative pressure chamber in the suction cup, and the suction force of the suction cup decreases, creating a risk of the device detaching from the inner wall of the carriage. Therefore, the carriage maintenance personnel are required to press the suction cup in time to maintain the suction force of the suction cup. However, the suction force of the suction cup in the above device cannot be displayed intuitively, and it is difficult for the carriage maintenance personnel to restore the suction force of the suction cup in time within a short period of time after the suction force of the suction cup decreases. For this reason, we propose a rail transit anti-collision device for transportation engineering. Utility Model Content

[0024] In this embodiment, preferably, the elastic linkage component also includes a guide groove 14 opened on the side wall of the movable plate 11, and the inner wall of the guide groove 14 is slidably connected with a positioning block 15, and the positioning block 15 is fixed to the front of the assembly plate 1, and the guide groove 14 and the positioning block 15 cooperate to guide the movable plate 11, so that the movable plate 11 can only move along a fixed path, and a spring 16 is fixed between the side wall of the positioning block 15 and the inner wall of the guide groove 14, and when the movable plate 11 moves in a direction away from the turntable 6, the spring 16 elastically contracts.

[0026] In this embodiment, preferably, a rubber pad 17 is fixedly provided on the side of the piston plate 9 opposite to the turntable 6, and the rubber pad 17 is against the inner wall of the movable groove 8. The rubber pad 17 can enhance the sealing between the piston plate 9 and the inner wall of the movable groove 8, and prevent air from entering the area between the piston plate 9 and the suction cup 13 in the movable groove 8.

At this time, the area between the piston plate 9 and the suction cup 13 in the movable groove 8 is in a negative pressure state, and the spring 16 cannot rebound and pull the piston plate 9 to move in the direction away from the suction cup 13, thereby adsorbing and fixing the assembly plate 1 on the inner wall of the subway car through the plurality of suction cups 13. When the passenger collides with the sponge pad 3 due to unstable standing in the car, the sponge pad 3 undergoes elastic deformation. Absorb part of the impact force to avoid injury to passengers. When the assembly plate 1 is fixed to the inner wall of the subway car due to long-term adsorption, some air enters the area between the piston plate 9 and the suction cup 13 in the movable groove 8, causing the adsorption force of the suction cup 13 to decrease, the spring 16 rebounds and pulls the piston plate 9 to move away from the suction cup 13, and the movable plate 11 moves toward the turntable 6. During this process, the movable plate 11 drives the turntable 6 to rotate clockwise through the linkage rod 12, and the turntable 6 drives the two pointers 7 to rotate synchronously, so that the reading of the pointer 7 on the scale 5 changes. The subway car maintenance personnel visually observe the reading of the scale 5 pointed by the pointer 7 through the observation window 4 opened on the side wall of the sponge pad 3, and can accurately judge the adsorption strength of the suction cup 13, and then press the suction cup 13 in time to restore the adsorption strength, thereby ensuring the stability of the assembly plate 1 adsorbed and fixed to the inner wall of the subway car.
