Abstract
The utility model discloses a conveniently-installed lifting oil cylinder for a forklift. The oil cylinder comprises a cylinder barrel and a piston rod, wherein a cylinder cover, on the extending end of the piston rod, is arranged on the end portion of the cylinder body, the end portion of the extending end of the piston rod and the bottom of the cylinder barrel are respectively provided with a ring-shaped fixing plate, and each ring-shaped fixing plate is provided with installation holes. The bottom of the cylinder barrel is provided with an oil inlet pipe opening communicated with a hollow cavity of the cylinder barrel. An oil return pipe opening, close to the cylinder cover, is arranged on the side wall of the barrel cylinder. The cylinder cover is in sealed connection with the contact portion of the extending end of the piston rod through a sealing element. A piston on the end portion of the piston rod is matched with the inner wall of the cylinder barrel through a supporting frame in a sliding mode. The supporting frame is in sealing fit with the inner wall of the cylinder body through a sealing ring. The end portion of the extending end of the piston rod and the bottom of the cylinder barrel are respectively provided with the ring-shaped fixing plates and installation holes, so the oil cylinder brings convenience to installation and replacement of the oil cylinder, changes lengths of the replaced cylinder barrel and the piston rod and structures of a portal frame according to different lifting heights to meet different specification requirements, is good in stability, and meets application requirements.
Description
Technical field
The utility model relates to a kind of oil cylinder, relates in particular to a kind of convenient hoisting cylinder for fork truck of installing.
Background technique
To need to drive the pallet fork lifting by door frame during fork truck work, and the lifting of door frame just need to use hoist cylinder, need to change during different rise height and use different cylinder barrel and piston rod, therefore, also to be convenient to installation and removal, and existing cylinder structure is installed inconvenience, is inconvenient to change inefficiency.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of convenient hoisting cylinder for fork truck of installing to be provided, solved existing cylinder structure inconvenience is installed, being inconvenient to change the problems such as inefficiency.
The utility model is achieved through the following technical solutions:
A kind of convenient hoisting cylinder for fork truck of installing, include cylinder barrel and piston rod, it is characterized in that: the cylinder barrel end of described piston rod external part is equipped with cylinder cap by guide sleeve, the bottom of described piston rod external part end and cylinder barrel is respectively equipped with annular fixed plate, be distributed with mounting hole on the described annular fixed plate, the bottom of described cylinder barrel is provided with the oil-feed mouth of pipe that is communicated with the cylinder barrel cavity, is provided with the oil return mouth of pipe near the cylinder cap position on the described cylinder barrel sidewall; The contact position of described cylinder cap and piston rod external part is tightly connected by Sealing, and the piston of described piston rod end is slidingly matched by bearing support and inner wall of cylinder, and is sealed and matched by seal ring between supporting frame and the inner wall of cylinder.
Described piston rod external part is fixedly connected with door frame by inserting fixing pin in the mounting hole on the annular fixed plate, and described cylinder barrel the inner is fixedly mounted on the frame fitting seat by inserting fixing pin in the mounting hole on the annular fixed plate.
Described cylinder cap also is provided with dust ring with the contact position of the piston rod that stretches out.
Its principle is: the structural design that is respectively equipped with annular fixed plate and mounting hole by the bottom of piston rod external part end and cylinder barrel, make itself and door frame and frame fitting seat adopt the plane to cooperate installation fixing, installation and the replacing of oil cylinder have been made things convenient for, can adapt to according to the structure that the difference of lifting altitude changes the length of changing cylinder barrel and piston rod and door frame the requirement of different size, and good stability, satisfied usage requirement.
The utility model has the advantages that:
The utility model is respectively equipped with the structural design of annular fixed plate and mounting hole by the bottom of piston rod external part end and cylinder barrel, installation and the replacing of oil cylinder have been made things convenient for, can adapt to according to the structure that the difference of lifting altitude changes the length of changing cylinder barrel and piston rod and door frame the requirement of different size, and good stability, satisfied usage requirement.
