The invention discloses a hydraulic oil cylinder protection device for an excavator. The hydraulic oil cylinder protection device comprises a hydraulic oil cylinder main body, an operating mechanism,an oil cylinder top cover, a protection mechanism, a protection tube, a sealing cover, a through groove, a through groove, a sealing plug, a filtering mechanism, a connecting rod, a fixed rod, a filter screen, a slider and a clamping mechanism. The hydraulic oil cylinder protection device for the excavator has beneficial effects as follows: when hydraulic oil enters the protection tube, the hydraulic oil firstly falls onto the filter screen, impurities and dust in the hydraulic oil are convenient to filter, so that the hydraulic oil is subjected to primary filtering before entering the hydraulic oil cylinder main body, a large amount of dust and impurities can be prevented from entering the hydraulic oil cylinder main body, and normal use of the hydraulic oil cylinder main body is guaranteed; and furthermore, after the device is used, a user can directly open the sealing cover to drive the connecting rod to move, the filter screen is separated from the inside of the protection tube, therefore, the filter screen is conveniently dismounted, cleaning of the filter screen is convenient, blockage of the filter screen is prevented, and normal use of the hydraulic oil cylinder main body is further guaranteed.
Description
technical field [0001] The invention relates to a protective device for a hydraulic cylinder, in particular to a protective device for a hydraulic cylinder of an excavator, and belongs to the technical field of hydraulic cylinders. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust de...
