A deep-sea self-protection and self-locking oil cylinder

Abstract

The invention discloses a deep sea self-protection self-locking oil cylinder. The deep sea self-protection self-locking oil cylinder comprises an oil cylinder barrel. The front end cover of the oil cylinder barrel is installed at one end of the oil cylinder barrel, and the rear end cover is installed at the other end of the oil cylinder barrel, an oil cylinder piston is installed on the inner wallsurface of the oil cylinder barrel, an oil cylinder piston rod extends out the middle of the oil cylinder piston, the oil cylinder piston rod penetrates through the front end cover of the oil cylinder, and oil cylinder pulling rod is installed on both the outer side wall of the front end cover of the oil cylinder and the outer side wall of the rear end cover of the oil cylinder; oil cylinder self-locking valves are installed on the lower parts of the front end cover of the oil cylinder and the rear end cover of the oil tank, the two oil cylinder self-locking valves have the same structure andare symmetrically arranged, the installation structure of the oil cylinder self-locking valve in the rear end cover of the oil cylinder are that a step hole is horizontally arranged below the oil cylinder rear end cover, a self-locking valve core is installed in the step hole, the self-locking valve core is in a cruciform structure, the head of the self-locking valve core is connected with the inner part of the oil cylinder barrel in a butt-joint mode, the outer circumferential surface of the self-locking valve core is connected with the inner wall surface of the step hole through a self-locking valve sealing ring, self-locking valve adjusting bolts are installed on the rail part of the self-locking valve core through self-locking springs, through holes communicated with the step hole areformed in the lower part of the step hole. According to the deep sea self-protection self-locking oil cylinder, working is reliable, and the self-locking effect is good.

Description

technical field [0001] The invention relates to the technical field of underwater hydraulic components, in particular to a deep-sea self-protection and self-locking oil cylinder. Background technique [0002] With the development of human beings, land resources are increasingly scarce, while the ocean covers about 70.8% of the earth's surface, containing rich biological, mineral, chemical and power resources, and is one of the last territories available to human beings. The development of deep-sea resources has received more and more attention, and the development equipment has become more and more diverse. The hydraulic system has the advantages of strong carrying capacity, high power density, and convenient speed regulation, and is widely used in the development of deep sea resources. Since the deep-sea environment is not convenient for maintenance, each repair must be floated to the sea surface or even returned to land, which is time-consuming and laborious, so it is ext...
