Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and in particular to a material handling device for tunnel construction. Background Art

[0002] Tunnels are engineering structures buried in the ground and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of the tunnel body and the tunnel portal. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long and large tunnels also have special ventilation and lighting equipment. During tunnel construction, materials need to be transported out of the tunnel or external raw materials need to be transported into the tunnel for construction.

[0003] The existing publication number CN216004496U discloses a material handling device for tunnel construction, including a handling device body, the handling device body including a drive device, movable wheels connected to both sides of the drive device, a control layer connected to the rear end of the drive device, and a base connected to the bottom surface of the control layer. The material handling device for tunnel construction activates a hydraulic cylinder to drive the material box down during unloading, and when the connecting rod descends, the slide is driven to rotate to a vertical state. At the same time, the ball bearing slides on the inner side of the slide to form a balance with one side of the hydraulic cylinder. The material box slides down along the inner side of the through groove and contacts the ground, achieving the beneficial effect of normal unloading in narrow areas in the tunnel. By the material box sliding down along the inner side of the through groove and contacting the ground, the drop is eliminated so that the worker and the material box are on the same horizontal line, achieving the beneficial effect of not requiring workers to get on and off the vehicle to carry the material during loading, improving efficiency and reducing the physical burden on workers.

[0004] In view of the above-mentioned prior art, although the hydraulic cylinder is started to drive the material box to descend during unloading, and with the cooperation of the connecting rod and the slide plate, the material box slides downward along the inner side of the through groove and contacts the ground, achieving the beneficial effect of normal unloading in narrow areas in the tunnel, but the lifting and lowering of the material box is only supported by the telescopic end of the hydraulic cylinder on one side, which will lead to uneven load distribution. When transporting heavier materials, the single-sided support is prone to tilt or instability, increasing the risk of overturning. Therefore, the support of the single-sided hydraulic cylinder limits the maximum load-bearing capacity of the material box. For heavier tubular materials, such as large steel pipes, concrete pipes, etc., the single-sided hydraulic cylinder may not be able to provide sufficient supporting force, resulting in the handling equipment being unable to work normally. In order to solve the above problems, a material handling device for tunnel construction is now proposed.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
