Technical Field
[0001] The utility model relates to the technical field of anti-collision and buffering, in particular to an anti-collision and buffering connecting device for vehicles and people in tunnels. Background Art
[0002] A mining vehicle coupling is a mechanical device used to connect the various components of a mining vehicle. Its primary function is to transmit power and accommodate relative motion and angular changes between vehicles during operation, particularly in complex mining conditions. Mining operations often involve rough, uneven roads, requiring vehicles to frequently turn, climb, and descend hills. The universal coupling ensures stable power transmission from the tractor to the trailer while allowing for a certain amount of pitch, yaw, and twisting motion between the two vehicles, ensuring normal operation and transport.
[0003] Existing mining vehicle connection devices usually do not have a buffer structure. When a collision occurs after the connection device is connected to two or more mining vehicles, the connection device is easily damaged due to the inertia of the vehicle. Therefore, a collision-proof and buffering connection device for level tunnel vehicles is needed to solve the above problem. Utility Model Content

An anti-collision buffer connection device for a mine vehicle in a tunnel is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a collision-proof buffer connection device for vehicles and people in flat tunnels, comprising a buffer sleeve, a connecting tail fixedly connected to the interior of the buffer sleeve near one end, a telescopic pull rod provided inside the buffer sleeve, the telescopic pull rod is fixedly connected to the connecting tail, one end of the telescopic pull rod is fixedly connected to a connecting plate, a buffer spring is provided on the surface of the telescopic pull rod, the two ends of the buffer spring are respectively fixedly connected to the connecting plate and the connecting tail, a connecting head is embedded in the interior of the connecting plate, a pin shaft passes through one end of the connecting head, both ends of the pin shaft pass through the connecting plate and are fixedly connected to fan-shaped limiters, and the surfaces of the connecting plates are fixedly connected to half-moon limiters.
[0006] Preferably, a lifting ring is fixedly connected to the top of the buffer sleeve near the center.
[0007] Preferably, the fan-shaped limit is compatible with the half-moon limit.
[0008] Preferably, a connection hole is provided on the surface of the connection tail, and a limiting groove is provided on the inner wall of the connection hole.
[0009] Preferably, a pin hole is provided on the surface of the connector.
[0010] Preferably, the edges of the connecting head and the connecting tail are rounded.
[0011] Compared with the prior art, the advantages and positive effects of the present invention are:
[0012] 1. In the present invention, when a vehicle collides, the force exerted by the connecting tail and the connecting plate on each other can be buffered by the buffer sleeve and the buffer spring between the connecting tail and the connecting plate, thereby preventing the connection of the connecting device from being damaged due to a large force, thereby increasing the service life of the device.
