Self-moving cable bridge

Abstract

The invention belongs to the technical field of auxiliary equipment for coal mining, in particular to a self-moving cable bridge. The self-moving cable bridge comprises a main cable cabin, a main longitudinal beam, a main cross beam, an auxiliary cable cabin, an auxiliary longitudinal beam, an auxiliary cross beam. A PLC, a control lead, a main roll shaft, an auxiliary roll shaft, a moving oil cylinder, a cable, retractile bridges and fixed bridges, wherein the retractile bridges and the fixed bridges are arranged horizontally in pairs. According to the self-moving cable bridge, the cable is stored at the top of a tunnel, so that the top space of the tunnel is fully utilized, the cable has adequate safety clearance with people, and the people walk and work smoothly in the lower space; thecable is stored in the cable cabin of a bridge frame, so that the cable is fully protected, the people cannot be harmed by cable leakage; the cable moves forward automatically in real time with the advance of a working surface, so that the mechanization and automation of cable movement are realized; and the cable management realizes high utilization rate of tunnel space, wide operation space, safety and reliability, simple operation and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of coal mining auxiliary equipment in coal mines, in particular to a self-moving cable bridge. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. [0003] In the coal mining face of the coal mine, there is cable suspension and management, and the method of cable slideway or cable car is generally used. [0004] There are too many shielded ends in the two existing methods: on the one hand, there are many cables, which occupy the space in the middle and lower part of the roadway, which not only affects the safety of pedestrians, but also has a small safety gap between cables and personnel or tools, and p...

Problems solved by technology

[0005] The purpose of the present invention is to provide a self-moving cable bridge, to solve the existing two ways proposed in the above-mentioned background technology, there are too many shielded ends: on the one hand, there are many cables, which occupy the space in the middle and lower part of the roadway, not only It affects the safety of pedestrians, and the safety gap between the cable and personnel or tools is small, and personnel or tools are often easy to damage the cable. If the cable leaks, it will seriously threaten the safety of personnel. Every time the cable moves forward, it needs to invest a lot of manpower and material resources, causing A certain waste of manpower and material resources

Moreover, the two methods are difficult to adapt to the problem of the situation with a large roadway slope
