Tension detection device and method for measuring steel wire rope of mining elevator

Abstract

The invention discloses a tension detection device and method for measuring a steel wire rope of a mining elevator. The detection device comprises a laser sensing mechanism and a laser target; wherein the laser sensing mechanism comprises a magnetic supporting block, a base, a supporting rod, a connecting block, a guide rail, a sliding block, a laser displacement sensor, a push rod, a handle, a mounting head, a rotating block, a clamping groove and a clamping groove; the laser target comprises a mounting plate, a clamping block, an aluminum plate and a magnet. According to the invention, displacement continuous measurement can be carried out on one point position on the steel wire rope, the measurement frequency is fixed, measurement signals can be collected and processed, the tension rebound time difference is finally obtained, and compared with traditional manual detection, the detection error is smaller, the detection safety is higher, and the practicability is higher. Therefore, the problems that in the prior art, manual detection of the tension of the steel wire rope of the elevator is large in error and inconvenient to operate, and potential safety hazards exist in the actual detection process are solved.

Description

technical field [0001] The invention belongs to the field of mine hoist detection, in particular to a tension detection device and method for measuring the steel wire rope of a mine hoist. Background technique [0002] In the coal mining process, the hoist is indispensable, and the hoist is erected in the mine for the transfer of objects such as ores in the mine. In actual mining operations, it is necessary to check the tension of the wire ropes of the hoist once a week, and the rebound time difference of the tension of each rope cannot exceed 10%. If it exceeds, there will be safety hazards, and the wire ropes need to be replaced. [0003] The purpose of the above detection is to require the static tension of several steel wire ropes to be basically consistent. In the prior art, the static tension of the steel wire rope cannot be directly measured in reality. The main detection method is to measure the rebound time indirectly. The existing measurement method is manual mea...
