An electronic control device for a mechanical speed-regulating mine hoisting winch

Abstract

The invention relates to the technical field of mining hoisting winches, and discloses a novel mechanical speed governing electric control device for a mining hoisting winch. The winch comprises a disk brake, a disk speed governing brake, a hydraulic unit, a disk brake valve electric control unit, a disk speed governing brake electric control unit and a PLC (programmable logic controller) control unit, wherein the hydraulic unit is connected with the disk brake and the disk speed governing brake; the disk brake valve electric control unit and the disk speed governing brake electric control unit are connected with the hydraulic unit; the PLC control unit is connected with the disk brake valve electric control unit and the disk speed governing brake electric control unit. According to the device, the magnitude of oil pressure can be electrically controlled to control the magnitude of braking force applied to a speed governing disk by the disk speed governing brake and the disk brake, and the device has the advantages of convenience in operation, safety and reliability.

Description

technical field [0001] The present invention relates to the technical field of mine hoisting winches, and more specifically relates to an electric control device for mechanical speed regulating mine hoisting winches. Background technique [0002] At present, the safety system of the existing hoisting winch adopts block brake braking, which relies on the counterweight to achieve the required braking force. power. Its disadvantages: 1. The block brake is used as a safety brake. The braking force is realized by the counterweight, which is safe for the winch when it is overloaded; 2. The working radius of the handle pulled by the operator is 800mm~ Between 1200mm, the adjustment speed cannot be well controlled, the braking torque is small when the speed is adjusted, and the required braking torque cannot be realized, and the operator is prone to fatigue, the operation is unsafe, and dangerous accidents are prone to occur. Contents of the invention [0003] The object of the ...
