Underground coal mine sensor lifting device

Abstract

The invention discloses an underground coal mine sensor lifting device. The underground coal mine sensor lifting device comprises a crank, a hanging rod, a plurality of directional pulleys, a steel wire rope and a sensor hanging slot, wherein the cranks is arranged on the hanging rod, and the hanging rod is arranged on the top of a roadway by a fixed bolt; the directional pulleys are arranged on the hanging rod through a pulley bracket; one end of the steel wire rope is connected to the crank while the other end of the steel wire rope penetrates the directional pulleys and is connected to thesensor hanging slot, and a sensor is arranged in the sensor hanging slot; the crank rotates positively and negatively to drive the steel wire rope to drive a sensor hanging hole to lift to displace the sensor in the positions of the directional pulleys. The underground coal mine sensor lifting device can lift the sensor quickly and solves the problem of difficulty in daily replacement and verification and maintenance. When it is needed to take down the sensor, it is only needed to rotate the crank gently, the sensor is to fall off and unnecessary collision is reduced, so that a monitoring system is more stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of installing underground sensors in coal mines, and in particular relates to a lifting device for underground sensors in coal mines. Background technique [0002] The hanging of underground sensors in coal mines needs to comply with the prescribed suspension standards. Many roads or working places have high roadways, and various sensors need to be hung on the roof of the roadway with hooks. The hanging position is too high, resulting in replacement and adjustment. It is inconvenient to use the sensor and there is a risk of climbing operation. To ensure the safety of climbing, two people need to cooperate with climbing to remove the sensor, and the work progress is also greatly reduced while occupying personnel. Some existing simple sensor installations are hung with wire hooks. When the frequency of sensor maintenance and calibration is high, it is necessary to climb up when removing the sensor. At the same...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the sensor needs to be hung on the roof of the roadway with a hook, and the hanging position is too high, which causes the problem that it is inconvenient to replace and adjust the sensor and there is a risk of climbing operations. Provide a fast lifting sensor , a coal mine underground sensor lifting device that solves the problems of daily replacement, calibration and maintenance

The invention can quickly lift the sensor, which solves the problems of difficult daily replacement, calibration and maintenance. When it needs to be removed, just turn the hand crank lightly, and the sensor will land, reducing unnecessary collisions and making the monitoring and monitoring system more convenient. Stable and reliable
