A cable placement frame for coal mining lighting system

Abstract

The invention relates to a cable placement rack for coal mining illuminating system. The lower end face of a supporting plate is connected with upper ends of supporting rods, lower ends of the supporting rods are in rotational connection with wheels, the upper end face of the supporting plate is connected with two bearings through two first connecting rods, and a same column is fixedly inserted into the two bearings. After a cable is unwound in an appropriate length, the position of the cable is fixed by limiting devices, and rotation of the column driven by sagging of the cable under the gravity action is avoided. After the cable on the whole column is used up, a third screw rod can be rotated to separate from a nut, then an arc rod stops limiting the cable position, then second screw rods are rotated to separate second arc plates from a third arc plate so as to take out a fourth arc plate, and the cable is separated from the arc plate to realize use of the whole cable. The cable placement rack is simple in structure and operation and convenient to use, ordered placement of the cable is realized, and cable twining is avoided.

Description

technical field [0001] The invention relates to the technical field of coal mine mining auxiliary equipment, in particular to a cable placement frame used for a coal mine mining lighting system. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. In the process of coal mining, lighting and other equipment need to be connected by cables. As the mining time increases, the overall scope of the coal mine increases, and the lighting area increases, the length of the cable needs to be increased. Generally, the cables that need to be extended are stacked together. It is opened when it needs to be extended, and random stacking of cables is easy to cause cable entanglement and the like, so a cable placement frame is needed. Contents of the invention [0003] The purpose of the present invention is to provide a cable placement frame for ...
