Adjustable cord driving and switching mechanism of mine hoist

Abstract

The invention discloses an adjustable cord driving and switching mechanism of a mine hoist, comprising a walking drum web plate, a walking drum left hub, a gear sleeve, a cover, a gear, a triple coilspring, a spherical bearing, a pressure cavity, a main shaft, and the like and characterized by being controlled by hydraulic pressure and finishing the disengaging and engaging action by oil pressurethrust and the deformation force of the coil spring. The invention improves the barometric control of an original adjustable cord driving and switching mechanism into hydraulic control, integrates control sources of a brake system and an adjustable cord driving and switching mechanism into a hydraulic station, thoroughly discards an original barometric system, utilizes the functions of the hydraulic station and also achieves automatic cord adjustment, equipment simplification, simple and convenient operation, short modification period and time and labor saving.

Description

technical field [0001] The invention relates to the technical field of a mine hoist system, in particular to a mine hoist rope adjustment drive conversion mechanism. Background technique [0002] In the 1960s, my country introduced a batch of 4m double-barrel hoists made in the Czech Republic, and in the 1960s, my country imitated the KJ-type hoist. Most of these hoists are still in use. These hoists use a pneumatically controlled braking system with a heavy hammer as the braking force source, and a pneumatically controlled rope adjustment and replacement mechanism, which is also called a rope adjustment and replacement mechanism. This KJ type hoist equipment rope adjustment drive conversion mechanism is attached figure 1 shown. [0003] This rope adjustment driving conversion mechanism is mainly made up of traveling reel left wheel hub 2, gear sleeve 3, cover 4, three sets of replacement mechanism cylinders 5, gear 6, air supply head 8, three sets of disc springs 9, etc. ...

AI Technical Summary

Problems solved by technology

Replace the original pneumatically controlled brake system with a new type of disc brake system controlled by a hydraulic station, and the original equipment's rope adjustment drive conversion mechanism is still controlled by pneumatics, so the original air pressure system cannot be got rid of despite the transformation , the device does not simplify

In addition, during the rope adjustment process of the original equipment, the pressure change and the on-off state of the compressed air are controlled by a set of special air valves. The equipment links are complicated, there are many fault points, and the maintenance amount is large.
