The system comprises a first motor, a variable pump, a high-pressure pipeline, a first safety valve, a second safety valve, a first oil tank, a first quantifying motor, a second quantifying motor, a rotating speed sensor, a low-pressure pipeline, a throttle valve, a second oil tank, an overflow valve, a quantifying pump, a second motor, a one-way valve, a proportional direction valve, a buffer brake cylinder, an emergent brake cylinder and an electromagnetic reversing valve. The system realizes stable brake and high-reliability control of a mining elevator, and effectively improves the safety and the reliability of the mining elevator.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a highly reliable mining hoist hydraulic control system. Background technique [0002] In coal mine operation and production, mine hoist is the key equipment for mine production. The technical performance of mining hoists is not only related to the production efficiency, safety and reliability of mines, but also represents the overall development level of mining machinery. [0003] At present, the mining hoist is usually driven by a hydraulic system, and the braking resistance is provided through the brake disc. However, existing mining hoists generally have technical defects such as too severe braking impact and low safety and reliability. [0004] In order to overcome the technical defects of existing mine hoists, it is urgent to provide a highly reliable mine hoist hydraulic control system. Contents of the invention [0005] In view of the above-mentioned defects in the pr...
