AI Technical Summary

Technical Problem

The existing technology cannot realize automatic measurement of mine tunnel deformation, and workers need to regularly manually measure it, which poses safety hazards and inefficiency problems.

Method used

A mine tunnel deformation measurement device is designed, including a frame, measuring rod, spring, limit plate, warning light and alarm. The tunnel deformation is detected by the extrusion movement of the measuring rod, and the warning light and alarm are triggered through infrared switches to realize automatic measurement and timely reminder.

Benefits of technology

Automatic long-term measurement of tunnel deformation is realized, and downhole staff can be promptly reminded, the efficiency and safety of measurement are improved, and the need for manual intervention is reduced.

Abstract

The utility model discloses a mine laneway deformation measuring device, which belongs to the technical field of mining equipment and comprises a frame and a plurality of measuring rods, the frame is provided with a plurality of mounting grooves matched with the measuring rods, the measuring rods penetrate through the frame through the mounting grooves, and springs positioned on the outer sides of the measuring rods are mounted in the mounting grooves. And the outer side of the measuring rod is provided with a limiting piece matched with the spring. Through the arrangement of the measuring rod, the infrared switch, the warning lamp and the alarm, the frame can be installed in a roadway during use, the measuring rod can be extruded when the roadway deforms, the measuring rod can move towards the inner side of the frame, and when the measuring rod blocks infrared light emitted by the infrared switch, the warning lamp can warn the roadway. When the measuring rod moves, the warning lamp and the alarm can be started to remind underground workers, and meanwhile the workers can know the deformation of the roadway according to the moving distance of the measuring rod.
