[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, producing linear reciprocating (or oscillating) motion. It features a simple structure and reliable operation. Reciprocating motion can be achieved without a reduction gear, eliminating transmission backlash and ensuring smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure differential across it. A hydraulic cylinder essentially consists of a cylinder barrel and head, a piston and piston rod, a sealing device, a buffer, and an exhaust device. The buffer and exhaust devices depend on the specific application, while other devices are essential.

[0003] The hydraulic cylinder is an important part of the hydraulic system that drags the main working mechanism to directly perform external work and must be transported with caution. In the existing technology, the fixing method of the protective device used for the transportation of the hydraulic cylinder is cumbersome, resulting in low efficiency of hydraulic cylinder transportation and difficulty in meeting the needs of industrial production.
