[0002] Large hydraulic cylinders are widely used in various industrial fields. They are mainly power execution elements of the hydraulic transmission system of large lifting equipment, which are energy conversion devices that convert hydraulic energy into mechanical energy. Since hydraulic cylinders are usually large in volume and mass and have special installation positions, the equipment installation positions cannot directly carry out maintenance work. Special lifting tools or maintenance racks need to be made for maintenance work, which has high operation difficulty, high operation risk coefficient, is easy to damage the equipment, and cannot achieve standardization.

[0003] At present, in various fields, hydraulic cylinders mostly use jacks plus metal brackets to carry out maintenance operations on the cylinders. The maintenance platform is difficult to adjust and the maintenance operation is difficult; when the piston rod of the hydraulic cylinder is removed, effective load-bearing cannot be carried out, and additional lifting equipment needs to be set up for fixation, which poses risks of personal injury and equipment damage; there is no effective protection during the test and commissioning of the hydraulic cylinder, which will increase the risk of damage to the piston seal due to the long extension distance and self-weight drop of the piston rod during the horizontal commissioning test; the fixing method of the maintenance equipment is not firm enough, and slipping and falling accidents may occur during the maintenance process, posing certain operation risks;

[0004] Therefore, we have designed a maintenance platform device for large hydraulic cylinders and columnar equipment, which can provide adjustments in multiple directions and the function of synchronous movement of the maintenance platform device and the equipment, improve the maintenance work efficiency, reduce the adjustment difficulty of the hydraulic cylinder during maintenance, improve the safety factor during personnel operation, and ensure the safety and reliability of the equipment during commissioning and operation.
