Abstract

The invention relates to a high-flow high-pressure oil double-telescopic pipe oil supply method. The method is implemented by a high-flow high-pressure oil double-telescopic pipe oil supply device, and the device at least comprises a radial oil conveying pipe, a full body and an axial oil conveying pipe, and is characterized in that a cylinder of a telescopic oil pipe is arranged on a fixed beam; the axial oil conveying pipe penetrates through the cylinder and is connected with the cylinder in a sliding mode; the front end of the axial oil conveying pipe is connected with the full body; two ends of the full body are provided with a seal and a guide sleeve; the radial oil conveying pipe with a closed tail end penetrates through the middle of the full body; the radial oil conveying pipe is connected with the full body in a sliding mode; and the front end of the radial oil conveying pipe is connected with a hydraulic actuating mechanism through a straight-through flange. By the method, high-flow high-pressure oil supply of a motion part is realized, the radial displacement of the motion part deviating from the preset motion direction can be absorbed, and the problem of oil leakage brought by the eccentric axial oil conveying pipe is solved.

Description

technical field [0001] The patent of the present invention is a large-flow high-pressure oil supply method for a hydraulic actuator on a moving part, especially a large-flow high-pressure oil double telescopic tube oil supply method on a moving part that requires a large adjustment in the non-moving direction. Background technique [0002] The high-pressure oil supply of hydraulic actuators on moving parts can usually be realized through hoses, but it is not feasible to supply oil through hoses for hydraulic actuators that require high-pressure oil flow, because on the one hand, the larger the hose diameter, the higher the pressure resistance. Poor, large-diameter high-pressure hoses are hard to find, on the other hand, large-diameter high-pressure hoses are thick and have poor flexibility, and the advantages of hose oil supply are lost; if a single telescopic oil pipe device is used, there is only one straight line (in In the direction of movement) and one rotation with two...
