A tire moving system suitable for life-saving cabins in tunnel construction

Abstract

The invention belongs to the related field of tunnel construction rescue matching equipment and discloses a tire moving system suitable for a tunnel construction rescue capsule. The tire moving system comprises a main body frame formed by jointly and fixedly connecting two longitudinal brackets and a plurality of cross beams. The longitudinal brackets are arranged in the long axis direction of the rescue capsule. The opposite ends of the longitudinal brackets are each provided with a driving wheel, a matching driving motor and a matching reducer, and each driving wheel is connected with a plurality of driven wheels. The cross beams are arranged between the two longitudinal brackets in a crossing mode and are detachably connected to the lower side of a rescue capsule body. By means of the tire moving system suitable for the tunnel construction rescue capsule, the functions of going forward, going backward, 360-degree free turning and the like can be achieved in the mode of being compact in structure, convenient to control, safe and smooth, and the tire moving system can be well adapted to the complex road conditions of tunnel construction.

Description

technical field [0001] The invention belongs to the field of tunnel construction rescue supporting equipment, and more specifically relates to a tire moving system suitable for a tunnel construction rescue chamber. Background technique [0002] With the vigorous development of my country's traffic construction, more and more tunnel engineering safety problems appear in unfavorable strata such as weak surrounding rocks. In the construction of tunnels with weak surrounding rocks, due to unfavorable factors such as poor geological conditions, shallow surface covering soil, or tunnels passing through (building) structures, disasters such as deformation and landslides are extremely easy to occur during construction. In recent years, construction accidents in tunnels with weak surrounding rocks have occurred frequently, resulting in heavy losses of equipment and personnel, and great social impact. Subsequent investigations found that more than 70% of the landslides occurred at a ...

Problems solved by technology

In this case, during the construction of the tunnel, if the span of the excavation surface is limited, towing the rescue cabin will occupy the road and affect the normal construction process, resulting in an increase in the construction period; secondly, due to the temporary road traffic in the tunnel during construction The conditions are poor, mechanical vehicles come in and out frequently, or due to the fast construction speed of the tunnel, the position of the rescue cabin may often need to be moved, which brings great inconvenience to the construction; finally, considering that when the tunnel construction environment is dominated by soft soil , if the crawler mobile system is used, it will sink into the ground due to its own heavy weight, which will cause some inconvenience to the movement of the rescue cabin, especially the turning
