Anti-static Coal Mine Underground Power Box Unwinding Device Through Ladder Knives Scratching

Abstract

The invention discloses an anti-static electricity box off-line device for underground coal mine through step-type knife grinding. The device comprises reinforcing ribs, an output pipe, a movable off-line device, a mounting seat and supporting legs, the mounting seat is arranged on the outer side end surface of the movable off-line device and is fixedly connected with the movable off-line device at the same time, the output pipe is connected with the right end face of the movable off-line device in a penetrating mode, the water flow is atomized through an atomizing pipe, meanwhile, the internal gas is humidified, the humidified gas is used for eliminating static electricity on the surface of the wire body, meanwhile drying is carried out by using a drying rack, then the device continues tobe conveyed, the agglomeration is carried out through the matching frame; meanwhile, the blocking removal work is carried out through the wedge-shaped knife, so that the inner wire body coil and theexisting wire body are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a wire-removing device for an underground power box in coal mines which uses stepped cutters to scrape and prevent static electricity. Background technique [0002] The current wire withdrawal device of the power box usually performs the wire withdrawal work by discharging the gas passing through the area when the wire body is recovered, and recovering the wire body by pulling, but in this way, it is easy to cause: [0003] When performing thread withdrawal, the gas in the area where the thread body passes is discharged, but the internal dust cannot be discharged. At the same time, when the thread is pulled back, the static electricity generated on the thread body will cause the free dust to be adsorbed on the thread body. Long-term accumulation and agglomeration will cause damage to the skin of the wire body, which will affect the safe operation of the equipment, and the static electri...

[0002] The current wire withdrawal device of the power box usually performs the wire withdrawal work by discharging the gas passing through the area when the wire body is recovered, and recovering the wire body by pulling, but in this way, it is easy to cause:

[0003] When performing thread withdrawal, the gas in the area where the thread body passes is discharged, but the internal dust cannot be discharged. At the same time, when the thread is pulled back, the static electricity generated on the thread body will cause the free dust to be adsorbed on the thread body. Long-term accumulation and agglomeration will cause damage to the skin of the wire body, which will affect the safe operation of the equipment, and the static electricity on the wire body will easily cause excess charges inside the equipment, affecting the operation of the equipment
