Problems solved by technology

For example, by extracting the change of the operating current of the hoist to judge whether the hoist is off the road, this method will cause the off-road non-action or malfunction due to the current change caused by the current change is not obvious or the load bumps during transportation
Another example is through the change of the tension of the wire rope head sensor, the signal is transmitted to the hoisting machine room through the leaking cable to alarm, but it cannot be popularized and applied because of the inconvenient operation of the rope head and the immature technology.

Embodiment Construction

[0006] Combined with the accompanying drawings, the method for alarming when the inclined shaft is lifted and transported will be described in detail.

[0007] Use wires 3 to bridge between the transportation tracks 1 to ensure that the resistance change of the same track is relatively smooth. One end of the inclined shaft hoisting transport drop alarm device 6 is connected to the track 1, and the other end is connected to the hoist that is rigidly connected to the steel wire rope 2. On the roller bearing seat 4 of the hoist, it is judged whether the hoist is off the road by measuring whether the resistance between the hoist track and the wire rope has a sudden change. If there is a sudden change, the alarm device will be activated by the contact action of the resistance measuring instrument with the live contact. This can remind the hoist operator to stop running the off-road hoist to avoid accidents.

Abstract

The invention provides an inclined well lifting transportation path off road warning device. The inclined well lifting transportation off road warning device judges whether an elevator is off road or not according to measuring resistance between an elevator track and a steel wire rope, if sudden change happens, and a warning device is started through contact motion of a resistance measuring meter with electric contact. An elevator operator is warned to stop running the elevator off road, and therefore occurrence of accidents is avoided.

Description

technical field [0001] The invention relates to an alarm device for lifting and transporting off track in an inclined shaft. Background technique [0002] Inclined shaft hoisting and transportation slippage is an important problem that threatens mine safety. It is particularly urgent to call the police in time to avoid vicious events such as sports car accidents caused by wire rope breakage and damage to wellbore facilities. For this reason, the professional and technical personnel of mine have thought many ways to solve this problem. For example, by extracting the change of the operating current of the hoist to judge whether the hoist is off the road, this method will cause the off-road non-action or malfunction due to the current change caused by the current change is not obvious or the load bumps during transportation. Another example is that the signal is transmitted to the hoisting machine room through the leakage cable through the change of the tension of the wire ro...
