Abstract

The invention provides a flexible vortex power, automatic-deslagging and backlog-free hydraulic cylinder. The flexible vortex power, automatic-deslagging and backlog-free hydraulic cylinder mainly comprises a cylinder barrel, an end cover A, an end cover B, a piston rod, a piston, a buffering block, a guide sleeve and a buffering pad. The flexible vortex power, automatic-deslagging and backlog-free hydraulic cylinder is characterized in that the piston with a spiral runner plays a role in flexible vortex power, and the buffering block with a deslagging runner plays a role in automatic deslagging. Through a circular truncated cone blind hole with a spiral runner, the flexible vortex boosting power is started when the piston rod extends out and is in a buffering static state when the piston rod draws back. Automatic deslagging is realized through the deslagging runner on the buffering block. A backlog-free buffering static state when the piston rod extends out and accelerating starting when the piston rod draws back are realized through a 45-degree inclining annular oil path in a guide sleeve.

Description

technical field [0001] The invention relates to a flexible vortex power-assisted, automatic slag-cleaning and no-backlog hydraulic cylinder, in particular to a circular platform blind hole with a spiral flow channel to realize the flexible vortex power-intensive start and retraction when the piston rod is extended. Buffer static when the piston rod is extended; automatic slag removal is realized through the slag clearing channel on the buffer block; 45° inclined annular oil passage on the guide sleeve realizes buffer static without backlog when the piston rod is extended and accelerated start when retracting , which belongs to the technical research and development field of hydraulic cylinders. Background technique [0002] Hydraulic cylinders use the linear reciprocating motion of the piston to convert hydraulic energy into mechanical energy. However, due to the singleness of the current hydraulic cylinder structure, the following problems are caused: one is the large star...
