Problems solved by technology

Unbalanced load often causes damage to the hydraulic cylinder, especially the failure of the hydraulic cylinder seal
[0004] At present, people mainly adopt the following two solutions for the occurrence of unbalanced load of the hydraulic cylinder. One is to add joint bearings or ball joints at the end of the hydraulic cylinder, but this will increase the twisted length of the hydraulic cylinder and reduce the The stability of the pressure rod of the oil cylinder; the other is to add a flange in the middle of the hydraulic cylinder to fix it with the sliding beam, but this is easy to make the oil cylinder bear an unbalanced load, damage the seal, and cause oil leakage from the oil cylinder

Abstract

The invention provides a structure for preventing an oil cylinder from unbalance loading, and relates to the technical field of hydraulic oil cylinders. The oil cylinder is fixed to a base and can push a load to reciprocate, the structure for preventing the oil cylinder from unbalance loading comprises a first unbalance loading prevention assembly and a second unbalance loading prevention assembly, the first unbalance loading prevention assembly is arranged between the oil cylinder and the base, and the second unbalance loading prevention assembly is arranged between the oil cylinder and the load. The structure for preventing the oil cylinder from unbalance loading can effectively prevent the oil cylinder from unbalance loading, and oil cylinder sealing is protected.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil cylinders, in particular to a structure for preventing the oil cylinder from being unbalanced. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. Using hydraulic power to drive the extension and retraction of the piston rod, the piston rod can drive the load to move. At the same time, during the movement of the piston rod, The piston rod is also subject to compression or tension from the load. [0003] When the hydraulic cylinder is subjected to pressure or tension, the hydraulic cylinder also tends to bear partial loads. Unbalanced load often causes damage to the hydraulic cylinder, especially the failure of the seal of the hydraulic cylinder. [0004] At present, people mainly adopt the following two solutions for the occurrence of partial load of the hydraulic cylind...
