Description
Technical field
The utility model relates to a kind of hydraulic jack protective gear that is applicable to hydraulic construction machine and haulage vehicle.
Background technique
The hydraulic lifting of hydraulic construction machine and haulage vehicle generally adopts cylinder system at present.When high pressure oil enters after oil cylinder, piston rod just gets up object carrying support lifting.After lifting puts in place, object carrying support or decline or drop to original position by oil cylinder working-pressure with deadweight, lifting reaches its work object so repeatedly.But due to by the object carrying support of lifting or because of foozle, or because of position distortion, or because of reasons such as centre-of gravity shifts, easily produce the phenomenons such as left and right or front and back skew.Oil cylinder is generally fixed on fixing support with trunnion base, and piston rod and connecting head thereof can only left and right or front and back skew occur along with object carrying support.Get off for a long time, the piston rod on oil cylinder will inevitably be followed about object carrying support or front and back skew, and oil cylinder leakage of oil appears in the lighter, the outer wall generation serious friction of severe one oil cylinder inner wall and piston rod and cause oil cylinder the problem such as to scrap.For this kind of problem, general corrective measure is to configure high-performance sealed material more, increases setting sleeve, configuration high-abrasive material or increases the measures such as guiding length.Though these measures have certain effect, can not fundamentally eliminate the impact that object carrying support generation left and right or front and back skew bring.
Summary of the invention
The utility model object is to overcome above-mentioned the deficiencies in the prior art part, and a kind of hydraulic jack protective gear is provided.
The utility model designs a kind of hydraulic jack protective gear, fender bracket (3), the fender bracket that comprise oil cylinder (1), be positioned at piston rod (2) on oil cylinder, is positioned at oil cylinder bottom be provided with symmetrical trunnion base (4), for the fixing gudgeon bolt hole (5) of trunnion base, oil cylinder packs in trunnion base by the longitudinal axis (6) of oil cylinder bottom, and gudgeon bolt for trunnion base (7) is fixed on fender bracket by gudgeon bolt hole; Also comprise two side plates (8), in the middle of side plate, have side plate hole (9), can pack in the transverse axis (10) of protecting seat, side plate two and side bolt (11) approach place limited location portion (12), between limited part and side bolt, have certain interval; On the bolt of side, there is side nut (16), for the good side bolt of secured adjusted, thereby regulate the gap between side bolt and limited part; Side plate surrounding has four side plate bolt holes (13), side plate can be fixed on crossbeam (14).Gap between described limited part and side bolt can be controlled between 1mm to 5mm.In addition, the position that packs into transverse axis (10) at described side plate is also provided with pump nozzle (15), for add oiling agent between transverse axis and side plate hole.
Compared with prior art, the beneficial effect that the present invention makes new advances because of following characteristics generation.One, by side plate and limited part thereof are set, there is certain interval with the side bolt on fender bracket, thereby allow piston rod and cylinder top along with object carrying support skew occurs to rotate flexibly, oil cylinder can adapt to the skew between object carrying support and piston thus, just can there is not serious extruding and friction in oil hydraulic cylinder top inwall and piston rod outer wall, thereby improve the working life on oil hydraulic cylinder top yet; Its two, by setting, be provided with pump nozzle, for add oiling agent between transverse axis and side plate cover, further make the certain lubricated and flexibility of protection between fender bracket and side plate, extend the working life on side plate, cylinder top.
