Abstract

The invention relates to an internal and external combined mechanical self-locking hydraulic cylinder which comprises a cylinder block, a piston slidably connected in the cylinder block, a piston rodfixedly connected to the piston, an internal self-locking assembly arranged in the cylinder block, an external self-locking assembly arranged outside the cylinder block and a housing arranged on the external self-locking assembly in a sleeving manner. The housing is connected to the cylinder block and the external self-locking assembly separately, the piston rod is provided with a tooth part arranged on the surface of the piston rod, the external self-locking assembly comprises a gear and a gear brake connected to the gear, the gear is engaged to the tooth part, and the gear brake is connectedto the housing. By arranging the internal self-locking assembly and the external self-locking assembly inside and outside the hydraulic cylinder, separately, the hydraulic cylinder is locked internally and externally in a combined manner, so that high precision and high reliability of a long-time working position of the hydraulic cylinder are guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to an internally and externally combined mechanical self-locking hydraulic cylinder. Background technique [0002] Hydraulic transmission is widely used in agricultural machinery, engineering machinery, aerospace and other occasions because of its high power density, easy to realize stepless speed regulation, standardization, and high degree of automation. The hydraulic cylinder is an important component widely used in the modern industrial hydraulic industry. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has a simple structure and reliable operation. When the hydraulic cylinder is used to realize the reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various...
