Description

Technical Field

[0001] The utility model belongs to the technical field of black oil distribution valves, and in particular relates to a black oil distribution valve cleaning device. Background Art

[0002] During the tunneling process of the shield machine, in order to ensure the safe and stable operation of the equipment, it is necessary to detect the real-time changes in the torque of the cutter head, the speed of the main motor voltage, the current of the propulsion cylinder displacement, the pressure of each lubrication system oil level, the temperature of each hydraulic system pressure, and the flow rate. Among them, the earth pressure balance shield machine will be blocked and unable to output during the tunneling construction. It may be that the black oil distribution valve is blocked and cannot be output. In severe cases, it may cause the damage of the internal and external seals of the main drive. Due to the unclear situation in the warehouse, it is necessary to stop the advancement and dismantle the black oil distribution valve for inspection, but if the formation is complex and the amount of groundwater is too large, no further inspection can be done. It has brought great obstacles to the advancement task, so during the maintenance of the shield machine, it is necessary to ensure the maintenance quality of the black oil distribution valve. The internal structure of the black oil distribution valve is complex and not easy to disassemble. The operator is not familiar with its structure, which may make the actual cleaning effect poor and unable to output effectively. It increases the safety hazards caused by the inability to output black oil during the actual excavation process. Utility Model Content
