Description

Technical Field

[0001] The utility model relates to the technical field of coal mine auxiliary equipment, in particular to a device for artificially lifting a sensor. Background Art

[0002] The hanging of underground sensors in coal mines must comply with the regulations. The tunnels in many large tunnels or work sites are relatively high, and various sensors need to be hung on the tunnel roof with hooks. The hanging position is too high, which makes it inconvenient to replace and adjust the sensors, and there is also a risk of height operation. To ensure the safety of climbing, two people are required to cooperate to climb up and remove the sensors. While occupying personnel, the work progress is also greatly reduced.

[0003] Some existing simple sensors are installed by hanging with wire hooks. When the frequency of sensor maintenance and calibration is high, it is necessary to wait for high-altitude operations to remove the sensor. At the same time, the collision rate between the sensor and the top increases, which can easily damage the related sensors. Utility Model Content
