When in use, piston rod is when cylinder interior activity, and piston rod has part when passing in and out cylinder body, has exposed parts for current oil cylinder, and after using for a long time, the exposed parts of piston rod can have damage in atmosphere due to exposure. After the long-time use of oil cylinder, each junction of oil cylinder can be worn and torn comparatively serious, thus having a strong impact on the use time of oil cylinder.
Summary of the invention
The purpose of this utility model is in that to solve techniques discussed above problem; a kind of wearability improving cylinder bearing is provided; also make bearing pin effectively be lubricated and protect simultaneously; extend the life-span of bearing pin; improving work efficiency, reduce the cylinder mechanism of the upper leveling cyclinder of production cost, its technical scheme is as follows:
The cylinder mechanism of upper leveling cyclinder, including cylinder body, one end of described cylinder body is connected with cylinder head by bearing pin, is provided with inner sleeve in the other end of described cylinder body, and the inner place of described inner sleeve is provided with projection, and protruding and cylinder body inwall forms oil-feed groove; In described cylinder body, between inner sleeve and cylinder head, place is cavity volume; Being provided with saddle in described cavity volume, described saddle can slide in cavity volume along inboard wall of cylinder block, and one end of saddle is provided with plush copper, and when plush copper contacts with cylinder head, plush copper and inboard wall of cylinder block form fuel-displaced groove; The top of described cylinder body is provided with oil pipe, and described oil pipe offers oil filler point and oil outlet, and oil filler point one end of oil pipe is communicated with cavity volume by oil-feed groove, and oil outlet one end of oil pipe is communicated with cavity volume by fuel-displaced groove; Described cylinder body is positioned at the outer end place of one end of inner sleeve and is provided with retractable dustproof set, and one end of retractable dustproof set is fixedly installed on the outer wall of cylinder body.
Optimal way is, the junction between described cylinder head and cylinder body is provided with fibre bush.
Optimal way is, puts and be provided with fibre bush in described.
The cylinder mechanism of the upper leveling cyclinder that this utility model provides, when in use, fuel-displaced groove and oil-feed groove make the turnover oil of whole oil pipe become enhanced convenience, do not result in problem.
The further cylinder head of this utility model is worn pin shaft hole position and is installed fibre bush, improves the wearability of cylinder bearing, also makes bearing pin effectively be lubricated and protect simultaneously, extends the life-span of bearing pin.
The further inner sleeve place of this utility model is provided with fibre bush. Fibre bush makes the anti-wear performance between inner sleeve and piston rod better, it is possible to improve the wearability of inner sleeve, extends the use time.
This utility model adopts the welding of integrated balanced valve, it is not necessary to valve seat and valve partial installation, improves work efficiency, reduces production cost.
The beneficial effects of the utility model are: improve the wearability of cylinder bearing, also make bearing pin effectively be lubricated and protect simultaneously, extend the life-span of bearing pin, improve work efficiency, reduce production cost.
