Tunnel vehicle U-turn device

Abstract

The invention provides a tunnel vehicle turning device facilitating turning. The tunnel vehicle turning device comprises a rotary disc, elastic components and a rotary shaft, the rotary disc comprises a driving disc and a supporting disc, and a buffer disc is arranged between the driving disc and the supporting disc. A plurality of coaxial first annular rails are sequentially arranged on the upper surface of the buffer disc from the axis to the outside, a plurality of balls are arranged in the first annular rails, and second annular rails corresponding to the first annular rails are arranged on the lower surface of the driving disc. The elastic components are arranged between the supporting disc and the buffer disc, the rotary shaft penetrates through the axis of the driving disc, the axis of the buffer disc and the axis of the supporting disc, one end of the rotary shaft is fixedly connected with the driving disc, and the other end of the rotary shaft is connected with a driving system. According to the tunnel vehicle turning device, rotation of the driving disc is very easy, after a lorry runs onto the driving disc, vehicle turning can be achieved by rotating the driving disc, and the pressure on the driving disc from get-on and get-off operation of the lorry is effectively reduced through the elastic components between the buffer disc and the supporting disc.

Description

technical field [0001] The invention relates to a device for making U-turn convenient for vehicles, in particular to a U-turn device for tunnel vehicles. Background technique [0002] In the process of tunnel construction, trucks are often used for the transportation of building materials and muck. In order to increase the transportation capacity, trucks are often bulky, and the space in tunnels is often small. Trucks want to use them in narrow tunnels. U-turn is very difficult. Tunnels are generally divided into single-track tunnels and double-track tunnels. In a single-lane tunnel, the width of the tunnel is smaller than the turning radius of the truck, and the truck cannot turn normally in the tunnel; when the single-lane tunnel is short, the truck can directly reverse into the tunnel, load muck or unload building materials, and then start from the single-lane tunnel. Directly drive out of the tunnel; but when the single-lane tunnel is long, it is very inconvenient, and...

Problems solved by technology

However, due to the large size and heavy weight of the truck, the pressure on the turntable and supporting legs is very high. In this way, the load-bearing capacity of the turntable and supporting legs is very high. becomes very difficult, so a lot of force is required to turn the steering wheel, and the supporting legs and steering wheel are easily damaged in this condition

In addition, such U-turn devices are installed on the pit on the tunnel floor. When the tunnel is long, multiple such U-turn devices need to be arranged at intervals, which increases the construction cost and time.
