The invention provides a mining high-speed slippage preventive winch. The mining high-speed slippage preventive winch comprises a winch body, a hydraulic system and a control system, the winch body consists of a disc brake, the hydraulic system comprises a first pipeline and a second pipeline, the first pipeline is used for being connected with a movable drum of the disc brake, the second pipeline is used for being connected with a fixed drum of the disc brake, a first hand-operated brake is serially connected onto the first pipeline, a second hand-operated brake is serially connected onto the second pipeline, and a pressure release protective electromagnetic valve is connected onto the first pipeline between the first hand-operated brake and the movable drum and the second pipeline between the second hand-operated brake and the fixed drum, and electrically connected with the control system. The mining high-speed slippage preventive winch is provided with the pressure release protective electromagnetic valve, hydraulic oil in the disc brake can be unloaded by means of conducting the pressure release protective electromagnetic valve via the control system even if the first hand-operated brake and / or the second hand-operated brake are closed, so that the disc brake is smoothly switched on to realize braking, and high-speed slippage accidents are prevented.
Description
technical field [0001] The invention relates to the technical field of winches, in particular to a mine anti-magnification slip winch. Background technique [0002] At present, most of the large winches in my country's coal mines are controlled by PLC control systems, and protection and locking are generally set in the PLC control systems to improve the reliability and safety of the entire system. But, the comprehensive judgment protection link that prevents from enlarging and slipping about winch has not been set. [0003] The existing measures to prevent the winch from magnifying and slipping are to use the emergency stop button on the driver's console to control it artificially. Once the driver finds that the winch is about to zoom in and slide, he immediately presses the emergency brake button of the winch on the driver's console to brake the winch , in order to achieve the purpose of preventing zooming slip. However, when the mine hoisting winch is in the rope adjustm...
