Description
Technical field
The utility model relates to development machine advancing hydraulic pressure oil cylinder technical field, especially a kind of active anti-side load development machine advancing hydraulic pressure oil cylinder.
Background technique
Development machine is the machine for digging straight underground passage, in development machine working procedure, advancing hydraulic pressure oil cylinder on it can bear lateral load, and under situation is carried in high side, the piston rod of microcosmic upper cylinder is easily to lopsidedness, when causing piston rod to-and-fro motion, and the frictional force between guide cover is comparatively large, impulsive load is large, and long-time piston rod or guide cover can produce defect, finally cause the fracture of piston rod, working life is short.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome when high frequency side carries, and the deficiency ruptured easily occurs the piston rod of advancing hydraulic pressure oil cylinder, now provides a kind of long service life, without leaking outside active anti-side load development machine advancing hydraulic pressure oil cylinder.
The utility model solves the technological scheme that its technical problem adopts: a kind of active anti-side load development machine advancing hydraulic pressure oil cylinder, comprise cylinder barrel and be arranged on cylinder bottom and the cylinder cap at cylinder barrel two ends, piston and piston rod is provided with in described cylinder barrel, described piston rod one end is fixedly connected with piston, the other end is through described cylinder cap, described cylinder barrel is provided with oil supply hole, described cylinder cap offers annular housing, described oil supply hole is communicated with described annular housing, described cylinder cap inner ring wall is provided with the bit copper layer for slide-and-guide between cylinder cap and piston rod, the inner ring wall of described bit copper layer spreads all over and has micropore, described micropore is communicated with described annular housing.
This programme mesohigh lubricant oil enters annular housing by oil supply hole, distributed by annular housing and enter micropore, extreme pressure lubricant is through micropore, high pressure oil film can be formed between piston rod and bit copper layer, by high pressure oil film for piston rod provides towing force, this towing force can resist the lateral load suffered by piston rod, simultaneously lube pistons bar.
Preferably, the axes normal of described micropore is in the axis of described cylinder barrel.
Preferably, described micropore is evenly distributed on the inner ring wall of described bit copper layer, the high pressure oil film that formed between piston rod and bit copper layer can be made comparatively even, so that the towing force that high pressure oil film provides for piston rod is comparatively even.
Further, between described cylinder cap and cylinder barrel, be provided with two seals circle, leaking of effective prevention hydraulic oil.
The beneficial effects of the utility model are: active anti-side load development machine advancing hydraulic pressure oil cylinder of the present utility model by extreme pressure lubricant after micropore, high pressure oil film can be formed between bit copper layer and piston rod, in order to resist the lateral load suffered by piston rod, lube pistons bar, greatly extends the working life of hydraulic jack simultaneously.
