Description

Technical Field

[0001] The utility model relates to the technical field of underground pipe installation, in particular to a fixing clamping plate assembly of cables and liquid pipes for a monorail hydraulic moving device. Background Art

[0002] At present, most coal mines use fully mechanized mining technology. With the development of intelligent equipment and large-scale equipment, there are more and more cables and liquid pipes, and the cross-sections are getting larger and larger. During the mining process, the cables and liquid pipes in the fully mechanized mining face need to be withdrawn from the working face for recovery. In the monorail hydraulic device used underground, cables and liquid pipes are tied with plastic cable ties or nylon ropes and binding belts. This method has the following disadvantages: 1) Plastic cable ties have low strength and are easy to break when the liquid pipe is under pressure, and the fixing force is small and cannot be pressed tightly; 2) Nylon ropes and strapping belts are relatively smooth, and the high-pressure liquid pipe vibrates greatly during the reversing action, so they are easy to loosen after being tied. In addition, because the nylon ropes and strapping belts are relatively smooth, they cannot fix cables and liquid pipes for a long time; 3) Nylon ropes and strapping belts are easy to absorb water, and they age quickly after absorbing water. These shortcomings make the cables and pipes in the monorail hydraulic moving device constantly straighten and bend during the movement process. The cables and pipes in the original fixed position always slide. For example, the distance between the two pulleys is 3 meters, and the cables and pipes between the two pulleys are also about 3 meters. After the deflection is formed, the cables and pipes between the two pulleys may be 3 meters or only 2.5 meters. In this way, when the deflection is straightened to 3 meters again, the shorter cables or pipes will be broken after the displacement.

[0003] In summary, in order to address the problems of cables and liquid pipes being loosely fixed and fixing parts being easily damaged in underground coal mines, it is urgent to develop and design a fixing splint assembly for cables and liquid pipes for a monorail hydraulic mobile device.
