Abstract

The invention relates to a hydraulic control system for a cage supporting and locking device. A cooling chamber is arranged outside an oil cylinder of the cage supporting and locking device. The cooling chamber is communicated with a cooling water tank through a water return pipe. The side face of the lower portion of the cooling water tank is communicated with the upper portion of the cooling chamber through a water supply pipe. A temperature sensor is arranged on the inner wall of the cooling chamber. The temperature sensor is electrically connected with the input end of a cooling controller through a wire. The output end of the cooling controller is simultaneously and electrically connected with a water supply electromagnetic valve, a water pump and a water return electromagnetic valve. A front-cavity oil pressure sensor and a rear-cavity oil pressure sensor are connected with two input ends of a comparison controller respectively. An output end I of the comparison controller is electrically connected with an electromagnetic switch. An output end II of the comparison controller is electrically connected with an oil supply electromagnetic valve which is located on an oil supply pipe. By the adoption of the hydraulic control system for the cage supporting and locking device, automatic oil injection and automatic cooling can be achieved, the cage supporting and locking state can be displayed in real time, and mine construction is greatly facilitated.

Description

technical field [0001] The invention relates to a hydraulic control system, in particular to a hydraulic control system for a tank holding and locking device which can realize automatic control. Background technique [0002] At present, the hydraulic control system used in the support tank lock device cannot sense the state of the support tank lock at any time, and the cooling of the hydraulic oil is inconvenient. If the temperature of the hydraulic oil rises to a certain value, it will cause serious safety hazards and even cause explosions. Affected mine construction. Contents of the invention [0003] In order to solve the problems of low automation and inconvenient cooling of the hydraulic oil in the existing hydraulic control system, the present invention provides a hydraulic control system for a tank holding and locking device. The hydraulic control system can realize automatic oil filling, automatic cooling, and real-time The accurate display of the status of the ta...
