Abstract

The invention relates to a hydraulic cylinder and provides an integrated hydraulic cylinder with a bidirectional stroke limit function. The integrated hydraulic cylinder is used for achieving bidirectional piston rod stroke limit of the hydraulic cylinder from any cavity to another cavity on the basis that the basic functions of the hydraulic cylinder are achieved in narrow space. The integrated hydraulic cylinder is composed of a cylinder block, a big end cover, a piston, a guide sleeve, a sealing assembly, a limit valve, a stop check valve and a pipeline. The limit valve is composed of a small oil cylinder, a valve sleeve, a spring, a valve element and the like. The small oil cylinder is composed of an end cover, a small cylinder block and a small piston. The stop check valve is composed of a valve deck, a valve body, a valve rod and a valve cone. The limit valve is integrated into the big end cover of the hydraulic cylinder. The stop check valve is integrated into the cylinder block of the hydraulic cylinder. According to the integrated hydraulic cylinder, the limit valve and the stop check valve are integrated, and multiple functions are added on the basis of scarcely increasing the size of the hydraulic cylinder. The integrated hydraulic cylinder has the beneficial effects of being rich in function, compact in structure, high in integration level and the like.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a hydraulic component, in particular to an integrated hydraulic cylinder with bidirectional stroke limitation. Background technique [0002] A hydraulic cylinder refers to a hydraulic actuator that converts the pressure energy of the working medium into the mechanical energy for the movement of the piston rod of the hydraulic cylinder in hydraulic transmission. The hydraulic cylinder is simple in structure and reliable in operation, and has been widely used in hydraulic systems. [0003] The function of the existing hydraulic cylinder is relatively single, only converting hydraulic energy into mechanical energy. To realize the two-way stroke limitation of the piston rod from any cavity of the hydraulic cylinder to the other cavity, it is necessary to install a limit valve in the hydraulic system, which will make the hydraulic pressure The system is complex, the number of pipeline connecti...
