Protection and control device for preventing tail rope kink of hoisting machine

Abstract

The invention discloses a protection and control device for preventing tail rope kink of a hoisting machine. The device comprises an image acquisition device, an image identification device and a control device, wherein the image acquisition device is used for acquiring an image of a rotatable rope end coupler; the image identification device is used for judging whether a tail rope connected withthe rotatable rope end coupler is about to kink according to the image of the rotatable rope end coupler at a predetermined time and a predetermined place; and the control device is used for controlling a motor of the hoisting machine, and stopping the motor when the image identification device judges that the tail rope connected with the rotatable rope end coupled is about to kink. In the embodiment of the invention, by judging whether the tail rope connected with the rotatable rope end coupler is about to kink by using the image acquisition device and the image identification device, the operation of the hoisting machine can be stopped in time so as to avoid a serious accident.

Description

technical field

[0001] The invention relates to the technical field of mine mining, in particular to a protection and control device for hoist tail rope kinks. Background technique

[0002] The tail rope of the hoist is one of the necessary parts of the hoist, and most hoist tail ropes use round steel wire ropes. But in the actual application process, the tail rope often kinks, although the tail rope isolation device is provided at the bottom at present, it still cannot prevent the occurrence of the tail rope kink accident. If the tail rope kinks and cannot stop the operation of the hoist in time, it will not only cause damage to the tail rope, but also damage to the wellbore equipment, damage to the lifting container (skip or cage), and even cause a safety accident. The traditional solution is usually to manually judge whether the tail rope has been twisted, and then control the hoist to stop running. However, the reliability and accuracy of manual monitoring are poor, an...
