Problems solved by technology

Due to the limited height of the roadway, this will cause a lot of inconvenience to pedestrians and vehicles. If the vehicle is not careful, the cable will be damaged, causing the cable to leak and trip, which will affect the normal production in the mine, and there is a great potential safety hazard.
In addition, in order to improve the quality standardization (to make the cable straight), the roadway cable hooks are all hung on the angle steel, and the angle steel needs to be fixed by electric welding. For high-gas mines, underground electric welding has a great safety hazard

Embodiment Construction

[0007] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0008] A method for erecting double-layer cables, fixing a hanger 2 and two rows of cable hooks 1 connected to the hanger 2, each row of cable hooks 1 is composed of two single cable hooks connected, two rows of cable hooks The hook heads are outwardly connected to both sides of the hanger 2 respectively. A support member 5 is arranged between the lowermost ends of the two rows of cable hooks. The length of the support member 5 is consistent with the width of the hanger 2 . When installing and using, the hanger part at the top of the back-to-back cable hook is close to the anchor rod at the top of the mine roadway, fixed with bolts, and the back-to-back cable hook is fixedly connected to the top of the mine roadway.

Abstract

The invention relates to mine underground powder distribution equipment erecting methods, particularly to a double-layer cable erecting method. The method comprises fixing a pylon and two rows of cable hooks on the pylon, wherein every row of cable hooks is composed of more than one single cable hook, the hook heads of the two rows of cable hooks face outwards and are connected on both sides of the pylon, a support unit is arranged between the lower ends of the two rows of cable hooks, and the length of the support unit is identical to the width of the pylon. The double-layer cable erecting method shortens the length of a single row of cable hooks, omits electrogas welding fixation and improves the underground construction safety of high-gas mines.

Description

technical field [0001] The invention relates to a method for erecting underground power distribution equipment in a mine, in particular to a method for erecting double-layer cables. Background technique [0002] At present, in the mine roadway, the suspension of cables, at the beginning, several cables just adopt several joint cable hooks. When there are many cable loops, the cable hanging height can reach more than 2 meters. According to the coal mine safety regulations, the cable hanging height from the ground should not be less than 1.8 meters. Due to the limited height of the roadway, this will cause a lot of inconvenience to pedestrians and vehicles. A little carelessness will cause the cable to be damaged by the vehicle, causing electric leakage and tripping of the cable, which will affect the normal production in the mine, and there is a great potential safety hazard. In addition, in order to improve the quality standardization (to make the cable straight), the roadw...
