High-position push-type self-unloading device for rubber-tyred vehicles

Abstract

The invention belongs to the technical field of underground coal mine auxiliary transportation equipment and particularly relates to a high-position push type self-discharging device of a rubber-tyred vehicle. The problem that cargo compartment lifting and pushing cannot be achieved simultaneously through an existing self-discharging vehicle is solved. The high-position push type self-discharging device of the rubber-tyred vehicle comprises a front vehicle frame and a rear vehicle frame hinged to the front vehicle frame. The upper portion of the rear vehicle frame is connected with a lifting mechanism. The upper portion of the lifting mechanism is connected with a push type cargo compartment through a telescopic oil cylinder. The push type cargo compartment is connected with the lifting mechanism and the rear vehicle frame through a supporting rod assembly. Through the telescopic oil cylinder and a lifting oil cylinder, the function of lifting the cargo compartment to a certain height and pushing the cargo compartment backwards for a certain distance can be achieved. A drawer type supporting beam is arranged at the bottom of the rear end of a platform of the lifting mechanism and moves backwards along with the cargo compartment, and the function of supporting the cargo compartment through the platform is achieved. In addition, two support oil cylinders are arranged on the left side and the right side of the rear end of the rear vehicle frame, and the problem that when cargoes are lifted to a high position or pushed to a far position, the vehicle body stability and operation safety are poor is solved.

Description

Technical field

[0001] The invention belongs to the technical field of auxiliary transportation equipment in underground coal mines, and specifically relates to a high-position push-type self-unloading device for rubber-tyred vehicles. Background technique

[0002] The underground rubber-tyred dump truck is mainly used for the rapid transportation of coal mine bulk materials, small and medium-sized equipment and personnel. It is the main vehicle type suitable for modern mines. With the rapid and integrated development of underground tunnels in coal mines, dump trucks have played an increasingly important role as supporting equipment, which can quickly transport supporting materials such as bolts, wire mesh, pallets, and drill pipes to the anchor. Near the pole machine and automatically unload. However, as far as the current dump truck is concerned, the unloading height is fixed, and the material can only be unloaded along the height of the frame itself, and the position of the s...
