Automatic control device for tension of main rope of inclined shaft hoist for mine and method of using the same

Abstract

The present invention is in the technical field of mining machinery, in particular to an automatic control device for the tension of main ropes of a mine inclined shaft hoist and a method of using the same; the present invention includes a hoist and a mine car, and also includes a set of wireless Transceiver devices, detection components set outside the mine, speed control components and control components set on the mine car, the hoist includes a rope take-up roller set at the mine wellhead and a drive motor that drives the rope roll to rotate, the mine wellhead and the hoist There is a sky wheel between the machines. The height of the sky wheel in the vertical direction is higher than the wellhead and the rope take-up roller of the mine. There are detection components between the sky wheel and the mine wellhead, between the sky wheel and the hoist, and the detection components include a curtain plate, an infrared transmitter, an infrared receiver and a first pressure sensor; the invention can effectively solve the existing technology. There are problems such as poor precision and single function.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to an automatic control device for the tension of a main rope of a mine inclined shaft hoist and a method for using the same. Background technique [0002] With the application of automation systems, many mine hoist electrical control systems have realized automatic driving, which greatly reduces the labor intensity of drivers. However, it has not been possible to realize fully automatic operation of the inclined shaft hoisting. One of the main reasons is: when the tandem car is in the ground flat car factory, when it is run down, because there is no backward power, it needs to manually push the tandem car. The speed of the car is variable, and the winch driver needs to adjust the speed of the hoist drum according to the observed tightness of the main rope to match the speed of the worker's cart. If the drum rotates too fast and the main rope is too loose, the loose rope ...

AI Technical Summary

Problems solved by technology

[0005] First, the accuracy is poor, because the device in the above patent document can only detect the main rope with a large degree of slack, and when the hoist is running, the tension of the main rope has three types: tight, normal and slack. However, the device in the above patent document can only detect whether the main rope of the hoist is in a slack state, but cannot detect whether the main rope is in a tight state, and the main rope in a tight state is also not conducive to the normal and safe operation of the hoist abnormal state of

[0006] Second, the function is single, because the device in the above patent document does not have the ability to adjust the tightness of the main rope, it can only remind the driver to stop the operation of the hoist immediately through an alarm
