Abstract

The invention discloses a device for protecting and controlling tail rope kinking of a hoisting machine, comprising a detection device, an induction device and a control device, wherein, the detection device is arranged under a tail rope isolation beam in a wellbore and is touched by the tail rope when the tail rope kinks; the induction device is connected with the detection device to induce the tail rope to touch the detection device; the control device is connected with the induction device to stop the motor of the hosting machine when the induction device induces that the tail rope touchesthe detection device. The device of the embodiment of the invention can judge whether kinking occurs to the tail rope through the detection device and the induction device, thus timely stopping operation of the hoisting machine to avoid causing serious accidents.

Description

technical field [0001] The invention relates to the technical field of mine mining, in particular to a kink protection control device for a hoist tail rope Background technique [0002] The tail rope of the hoist is one of the necessary parts of the hoist, and most of the hoist tail ropes use round wire ropes. However, in the actual application process, the tail rope is often kinked. Although the tail rope isolation device is currently installed at the bottom, it still cannot prevent the occurrence of the tail rope kink accident. If the tail rope is kinked and the operation of the hoist cannot be stopped 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 lead to safety accidents. The traditional solution is usually to manually judge whether the tail rope is twisted, and then control the hoist to stop running. However, the reliability, accuracy and timeliness of manual ...
