Abstract

The invention provides an automatic control device of a mine auxiliary shaft elevator. The automatic control device comprises an elevator body and a car puller, wherein the elevator body comprises a safe door, a cradle and a front car arrester which is arranged inside a cage, the elevator body is provided with a detection switch detecting whether the cage is in place, the detection switch sends signals about that the cage is in place to the elevator body and a programmable logic controller (PLC), and the PLC respectively controls operation of the safe door, the front car arrester, the cradle and the car puller according to the received relevant signals. The automatic control device achieves concentrated and automatic control, control accuracy is strong, reliability is high, operation is convenient and rapid, and production requests of modernization safety and rapidness are met.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control device for a mine auxiliary shaft hoist. Background technique [0002] The auxiliary shaft of the mine is responsible for the multiple tasks of lifting underground waste rocks, transporting materials down the mine, and transporting workers up and down the mine. Among them, the task of lifting and transporting personnel, the driving system plays a very important role in the mine. [0003] Generally, the operation system of auxiliary shafts in mines is composed of actuators such as safety doors, cradles, carts, and front stoppers. Block open a pushcart machine move back one front block close one shaker retract one safety door to operate. Since the hoist in the auxiliary shaft of the mine is related to the safety of materials and the safety of personnel, it is required that the operating system for controlling the hoist must be safe, reliable, easy to...
