Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to an anti-collision type hydraulic oil cylinder. Background Art

[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, and with zero transmission backlash, the cylinder offers smooth motion. Consequently, it is widely used in hydraulic systems across various machines. The cylinder's output force 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 rod, a sealing device, a buffer, and an exhaust device. The buffer and exhaust devices are specific to the application, while other devices are essential.

Through the above-mentioned method, the hydraulic cylinder of the utility model can eliminate the assembly clearance error between the cylinder and the guide sleeve, can ensure high coaxiality accuracy between the guide sleeve and the cylinder after assembly, the assembly process is easier and more repeatable, making subsequent maintenance and disassembly more convenient, and the structure is simple and easy to process, which is convenient for mass production.

[0004] However, during the operation of the existing anti-collision hydraulic cylinder, the adjustment angle of the hydraulic cylinder is fixed. Therefore, when the hydraulic cylinder needs to lift an object at different angles, the object can only be translated within a certain range during the lifting process, which will affect the use effect of the hydraulic cylinder and greatly reduce the practicality of the hydraulic cylinder.

[0005] Therefore, in order to solve the above problems, an anti-collision hydraulic cylinder is proposed. Utility Model Content
