Description
Technical field
The utility model relates to the technical field of the oil cylinder of hydraulic hoist.
Background technique
The oil cylinder of existing hydraulic hoist comprises cylinder barrel, the fixedly connected rear end cover in the rear end of cylinder barrel, and the fixedly connected front cover of the front end of cylinder barrel places piston rod in the cylinder barrel, the fixedly connected piston in the rear end of piston rod, piston is equipped with in cylinder barrel.This structure, is inconvenient to install, is dismantled and keep in repair after long-term the use because front cover and cylinder barrel are fixed.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of oil cylinder of hydraulic hoist for convenience detach is provided, and can conveniently carry out the installation and the maintenance of oil cylinder.
The purpose of this utility model is achieved in that the oil cylinder of hydraulic hoist for convenience detach, comprises cylinder barrel, and the fixedly connected rear end cover in the rear end of cylinder barrel places piston rod in the cylinder barrel, the fixedly connected piston in the rear end of piston rod, and piston is equipped with in cylinder barrel; The front end inboard of described cylinder barrel radially is provided with the cylinder barrel groove, between the front end of cylinder barrel and the piston rod guide sleeve is set, guide sleeve comprises big outer diameter section and small outer diameter section, the front end of big outer diameter section is fixedlyed connected with small outer diameter section, big outer diameter section is equipped with in cylinder barrel, the guide sleeve groove radially is set on the small outer diameter section, be nested with card key and baffle ring on the small outer diameter section, the card key is arranged in the described cylinder barrel groove, baffle ring is arranged on the front side of card key, the fixedly connected axle bumper in the front side of baffle ring, axle bumper are arranged in the guide sleeve groove and are arranged on the front side of cylinder barrel.
The utility model is by above design, and it is spacing that guide sleeve has the card key to carry out forward, and there have axle bumper to carry out backward to be spacing, make guide sleeve can not move axially, and each component need not be fixedly connected, thereby made things convenient for assembly and disassembly to keep in repair, and also improved the working life of oil cylinder.
In order to strengthen wear resistance, between guide sleeve and the piston rod wear-resistant sleeve is set, wear-resistant sleeve uses copper sheathing, has replaced the supporting ring that general oil cylinder uses, and wear resistance is good.
In order to bear the effect of piston rod radial force and sealing, between guide sleeve and the piston rod supporting ring is set.
In order to make good sealing effect, between guide sleeve and the piston rod at least one is set and uses circle.
This special envelope is set, advantage such as it is low that this special envelope has frictional force, and nothing is creeped, and tripping force is little, and is high pressure resistant between guide sleeve and the piston rod.
In order to prevent that dust from entering, between guide sleeve and the piston rod dust ring is set, dust ring is arranged on the front side of supporting ring, axle circle, this special envelope and wear-resistant sleeve.
In order to strengthen static seal, at least one O shape circle is set between guide sleeve and the cylinder barrel.
