A crawler mobile system suitable for tunnel construction rescue cabin

Abstract

The invention belongs to the correlative field of tunnel construction rescue corollary equipment and discloses a crawler belt moving system suitable for a tunnel construction rescue capsule. The crawler belt moving system comprises a main body frame formed by fixedly connecting two longitudinal supports and a plurality of cross beams jointly, wherein the longitudinal supports are arranged in the long axis direction of the rescue capsule; one ends of the longitudinal supports are provided with driving wheels, matched driving motors and matched speed reducers, and the other ends of the longitudinal supports are provided with carrying wheels; crawler belts are arranged between the two corresponding wheels in a sleeving mode to achieve circulating movement; the cross beams are arranged between the two longitudinal supports in a crossing mode and are detachably connected to the lower side of a rescue capsule body; and moving parts borne by the two longitudinal supports are arranged antisymmetrically, and chain sheets of the crawler belts are of an uneven convex-concave structure. By means of the crawler belt moving system, functions such as advancing, retreating and 360-degree free turning can be achieved in the mode that the compact structure, convenient control, safety and stability are achieved, and the crawler belt moving system can well adapt 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 crawler moving system suitable for tunnel construction rescue cabins. 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; in addition, due to the temporary road traffic conditions in the tunnel during construction Poor, frequent entry and exit of mechanical vehicles, or due to the rapid construction of tunnels, it may be necessary to move the location of the rescue cabin, which brings great inconvenience to the construction
