Description
Technical field
The utility model is related to the guide technique field on mine shaft hoisting container, specifically provides a kind of rolling wheel pot
Ear buffer unit.
Background technology
Rolling cage shoe is arranged on hoisting container, plays certain guiding and cushioning effect.The knot of known rolling cage shoe
Structure mainly includes buffer, roller, support, base and frame etc..When hoisting container works in mine vertical shaft, rolling cage shoe meeting
Acted on by external force, now buffer plays certain cushioning effect, prevent roller from being acted on and be damaged by external force, therefore buffer
Played an important role in rolling cage shoe., it is necessary to adjust slow according to different mine vertical shaft situations in practical work process
The dsah-pot height of device is rushed, the dsah-pot of traditional rolling cage shoe buffer is used two above and below bearing pin connected mode, i.e. dsah-pot
End is fastened using bearing pin, and this kind of fixed form causes dsah-pot regulation bothersome, time-consuming, increases the workload of workman, reduces work
Make efficiency.In addition, easily enter coal dust, sewage etc. in conventional buffer cylinder, after the coal dust for entering dsah-pot is mixed with sewage,
Dirt is formed in cylinder, the buffering effect of dsah-pot is had a strong impact on, and dirt can not be discharged in cylinder for a long time, easily to slow
Rush the disc spring of cylinder, barrel and cause corrosion, cause buffer to fail, rolling cage shoe is lost effective buffering, substantially reduce roller
The service life of cage shoe, causes certain potential safety hazard.
In Patent No. CN201458454U patent document, a kind of hermetically sealed rolling cage shoe of liquid gas is disclosed.The structure
The hermetically sealed rolling cage shoe of liquid gas mainly have roller, hydro-pneumatic buffer, rocking arm, base, bumper bracket etc..Hydro-pneumatic buffer and
Roller uses hermetically sealed design, and bearing can realize hydrodynamic lubrication oil lubrication.Hydro-pneumatic buffer by gas spring, butterfly spring and
Hydraulic damping device is constituted.By the hydro-pneumatic buffer of the structure can quick apparatus with shock absorbing, still, due to liquid gas buffering
The piston rod of device is arranged on hydro-pneumatic buffer upper end, and dust is easily fallen into hydro-pneumatic buffer when piston rod is moved up and down, and causes
The cylinder of hydro-pneumatic buffer produces dirt, influences the buffering effect of hydro-pneumatic buffer.Meanwhile, above and below the hydro-pneumatic buffer of the structure
Two ends use bearing pin fastening means, are unfavorable for the regulation of hydro-pneumatic buffer height.
The content of the invention
In order to solve the problem of above is present, the utility model provides a kind of structure design advantages of simple, easy for installation, and
Coal dust, sewage can be effectively avoided to enter, so as to improve the rolling cage shoe buffer unit of the service life of rolling cage shoe.
To achieve the above object, the utility model provides following technical scheme：
A kind of rolling cage shoe buffer unit, including dsah-pot and butterfly spring A, butterfly spring A are arranged on dsah-pot cylinder
