Description

TECHNICAL FIELD

[0001] The utility model relates to a mine hoist detection device, in particular to a mine hoist steel wire rope tension detection device, belongs to mine hoist detection equipment technical field. BACKGROUND

[0002] In the coal mining process, the hoist is indispensable, and the hoist is erected in the mine for the transfer of ore and other objects. In actual mining operation, the tension of the hoist steel wire rope needs to be checked once a week, and the rebound wave time difference of each rope tension cannot exceed 10%, otherwise there is a safety hazard and the steel wire rope needs to be replaced.

[0003] The purpose of the above detection is to keep the static tension of the steel wire rope consistent. In the prior art, the static tension of the steel wire rope cannot be directly measured, and the main detection means is to indirectly measure by measuring the rebound wave, and the principle is that for the same type of steel wire rope, the oscillation frequency is proportional to the tension under the condition that the suspension length is consistent. The existing measurement method is manual measurement, and the specific measurement method is: at the wellhead, the steel wire rope is pushed and pulled by hand to generate oscillation, and the oscillation wave propagates downward along the steel wire rope to the suspension point and rebounds, and when the rebound wave reaches the wellhead, the amplitude can be observed to increase obviously, and a stopwatch is used to record the time of the oscillation wave returning to the wellhead. A plurality of steel wire ropes are measured to obtain the corresponding rebound wave time, and the rebound wave time difference in the specification is obtained by subtracting the minimum value from the maximum value, dividing the maximum value by 100. An invention patent with application number CN202111132369.4 discloses a tension detection device and method for measuring the tension of a mine hoist steel wire rope. The detection device comprises a laser sensing mechanism and a laser target. The laser sensing mechanism comprises a magnetic support block, a base, a support 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 block, a slot and a clamping groove. The laser target comprises a mounting plate, a clamping block, an aluminum plate and a magnet. The present application can continuously measure the displacement of a point on the steel wire rope, the measurement frequency is fixed, and the measurement signal can be collected and processed, and finally the tension rebound time difference is obtained. Compared with the traditional manual detection, the detection error is smaller, the detection safety is higher, and the practicability is stronger. The problem of large error, inconvenient operation and safety hazard in the actual detection process in the prior art is solved

[0004] However, the device still has the following problems: when the device detects, the laser target needs to be detached from the mounting head. Since the steel wire rope is located in the wellhead, it is difficult to collect the laser target after the detection is completed.

[0005] Therefore, the utility model provides a new solution. UTILITY MODEL CONTENTS
