Abstract

The invention discloses a hydraulic support pulley, which comprises a cylinder barrel, a parallel cap, a locking washer, a piston, a first sealing element, a second sealing element, a wear-resisting ring, a return spring, an anti-rotating shaft, a shaft sleeve, a positioning slide block, a support bracket, an oil nozzle, a pulley shaft, a bearing, a pulley and an oil inlet hole, the middle part ofthe outer circle of the cylinder barrel is provided with the anti-rotating shaft, the left end of the cylinder barrel is provided with the oil inlet hole, the right end of the cylinder barrel is provided with the support bracket, the support bracket is provided with the pulley shaft, the pulley shaft is provided with the pulley through the bearing, and the oil nozzle is arranged above the pulleyshaft. The left end of the cylinder barrel is also provided with the parallel cap through the locking washer, the piston is arranged in the cylinder barrel through the first sealing element and the second sealing element, the piston is internally provided with the return spring, and one end of the return spring is matched with the positioning slide block. The anti-rotating shaft is arranged in thepositioning slide block, the right end of the positioning slide block is fixedly connected with the support bracket. The support bracket is matched with the inner wall of the right end of the cylinder barrel through the shaft sleeve. The pulley has a multi-function effect of anti-rotation and positioning.

Description

technical field [0001] The invention relates to the technical fields of machinery and pneumatic hydraulics, in particular to a hydraulic support pulley. Background technique [0002] At present, there is no existing domestic reference technology for comparison, and ordinary oil cylinders cannot meet the requirements of special environments. Now invent a kind of anti-rotation, positioning, single operation, and form an integrated multifunctional new hydraulic element with the support pulley. The hydraulic support pulley of the present invention is invented by proposing design and using technical parameters in a special environment. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a hydraulic support pulley, which can solve the problem of anti-rotation, positioning, single operation, and a new hydraulic element integrated with the support pulley. [0004] In order to achieve the above object,...
