Embodiment 1

[0025] Such as figure 1 , 2 As shown, the mine cable protection device according to the present invention includes a channel steel 1 and a first fixing part 2. The channel steel 1 is provided with areas fixedly connected to the first fixing part 2 on both sides of the groove extending direction. The first fixing part 2 is provided with a first through hole 3 that can be installed with an expansion screw. According to the length of the tunnel, the cable is covered with a steel groove and fixed by the expansion screw, which can prevent the flying stone from damaging the cable; the opening of the channel steel 1 can be shaped like a bell mouth. Increase the capacity of the steel channel for cables.

Embodiment 2

[0027] Such as image 3 , 4 , 5, and 6, in the mine cable protection device of the present invention, the end of the channel steel 1 is provided with a connecting portion 4 at the corner, and the connecting portion 4 includes a steel plate 5, a groove stopper 6, and a third fixing portion 7 , the fourth fixed part 8, the groove stopper 6 is perpendicular to the steel plate 5 and fixedly connected, one end of the steel plate 5 is fixedly connected to the third fixed part 7, the third fixed part 7 is provided with a second through hole 9, and the steel plate 5. The other end is fixedly connected to the fourth fixing part 8, and the fourth fixing part 8 is provided with a third through hole 10; the end of the channel steel 1 along the groove extending direction is provided with a second fixing part 11 for connecting the connecting part 4, and the The second fixed part 11 is provided with a fourth through hole 12; the second through hole 8, the third through hole 9, and the fourt...

Abstract

The present invention relates to the field of cable laying technology, in particular to a mining cable protection device. The object of the present invention is to provide a mining cable protection device capable of preventing a cable from being damaged by flying stone. By providing a channel steel outside the cable, the damage caused by the blasting flying stone to the cable is solved. The miningcable protection device includes a channel steel, a first fixing portion, wherein areas fixedly connected with the first fixing portion are arranged on the two sides of the channel steel in the extending direction of the groove, and the first fixing portion is provided with a first through hole through which the expansion screw can be mounted. In the mining cable protection device, a steel channel is provided to prevent flying stone from damaging the cable; and a connecting portion is provided to lay the cable at the corner.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to a mine cable protection device. Background technique [0002] In the mine power supply system, due to the special mine environment, the failure rate of the power supply line is required to be much less than that of the low-voltage power supply. The power supply in the mining area is the weak link in the power supply system, and the working environment is poor. Especially during blasting operations, the flying rocks generated by the blasting pose a great threat to cable damage, which is directly related to the safety of the entire mining area. In the laying of mining cables in existing mining areas, cable hooks are often used to fix the cables on both sides of the roadway, which cannot effectively prevent the damage to the cables caused by blasting flying stones. Contents of the invention [0003] The object of the present invention is to propose a mine cable protection de...
