Description

[0001] The invention belongs to the technical field of hydraulic component cleaning, in particular to a cleaning device for hydraulic components. Background Art

[0002] A hydraulic system is usually composed of five parts: power elements, actuators, control elements, auxiliary elements and hydraulic media. The hydraulic cylinder is the actuator in the hydraulic transmission system, which converts hydraulic energy into mechanical energy during operation. The hydraulic cylinder relies on internal pressurization of hydraulic oil to achieve the extension and retraction of the piston rod. After long-term use, the inner wall of the hydraulic cylinder needs to be cleaned to ensure smooth movement of the piston inside.

[0003] A Chinese patent with publication number CN114505309B discloses a cleaning device for hydraulic components, including a machine body and a cleaning tank and a cleaning chamber opened on the machine body, a porous barrel being rotatably provided in the cleaning tank, a second motor being fixed to one side of the bottom of the machine body by a bracket, a side plate for closing the cleaning chamber being provided on one side of the machine body, a support plate being fixed to the lower part of one side of the side plate, two clamping blocks being provided on the upper part of one side of the side plate, a hydraulic cylinder being placed on the support plate and clamped between the two clamping blocks, a scrubbing disc being provided on the top of the cleaning chamber, a sliding column being coaxially fixed to the upper part of the scrubbing disc, a first motor being fixed to the upper part of the machine body, the first motor being used to drive the sliding column to rotate, a lifting mechanism being provided in the machine body, a nozzle being installed on the bottom wall of the cleaning chamber to realize rapid cleaning of the hydraulic cylinder, greatly improve cleaning efficiency, and be suitable for batch cleaning without the need for separate cleaning.

[0004] In the current existing technology, the hydraulic cylinder is cleaned by placing it in a cleaning tank and a cleaning bin respectively. However, when cleaning the hydraulic cylinder, the contact area between the support plate and the clamp block and the hydraulic cylinder cannot be brushed, resulting in incomplete cleaning of the outer wall of the hydraulic cylinder; and when the outside of the hydraulic cylinder is sprayed and flushed with a nozzle, the washed away oil and impurities are accumulated in the fixing device.
