Abstract
The utility model discloses a multi-stage upside-down oil cylinder with two hinged shafts and relates to the technical field of dump truck oil cylinders. The multi-stage upside-down oil cylinder with two hinged shafts comprises a base cylinder assembly, multiple stages of cylinder assemblies, a piston rod assembly, a cylinder bottom component and a sealing component, wherein the sealing component comprises a dustproof ring and two Y-shaped sealing rings; the base cylinder assembly comprises a base cylinder, a compression ring fixed on the base cylinder, a base cylinder hinged shaft seat and a base cylinder hinged shaft arranged on the base cylinder hinged shaft seat; the piston rod assembly comprises a piston rod and a piston rod hinged shaft arranged at the end of the piston rod; the base cylinder hinged shaft is hinged to a compartment, and the piston rod hinged shaft is hinged to a frame. By means of an installation mode with the two hinged shafts, the load-carrying capability is good. By means of the upside-down structure, a primary protective cylinder is not needed, and production cost is reduced. The Y-shaped sealing rings are installed with openings upward, therefore, pressure exists in a sealing area under the low pressure, and sealing performance under low pressure is ensured.
Description
Technical field
The utility model relates to oil cylinder of dumper technical field, specifically multistage pair of hinge upside-down oil cylinder for a kind of dumping car.
Background technique
Before existing oil cylinder of dumper is divided into, take blame for others and in take blame for others two kinds.In the conditions such as being subject to installing space, pressure of taking blame for others limit, be used for small-sized dumping car, market scope is smaller.Before take blame for others larger thrust can be provided, and installing space is larger, is used for medium-sized and heavy-duty tipper, the market demand is larger.Before dumping car, take blame for others as multistage single-action telescopic sleeve hydraulic cylinder, according to installation form, be divided into two hingeds and hinge Earrings type.
The hinge of hinge Earrings type oil cylinder is connected with vehicle frame, and earrings is connected with compartment, and joint shaft bearing is housed on earrings, and earrings and bearing thickness are all thinner, and the arm of force is smaller, and stressing conditions is poor, supports offset load resistance poor; Two hinge oil cylinders are all that stressing conditions is relatively good by stud connection up and down, and offset load resistance is more intense, but than hinge Earrings type oil cylinder many first class of protection cylinder.
In real work, due to actual conditions more complicated, such as work Uneven road, while walking the situation such as work, unbalance loading is unavoidable, and this just requires oil cylinder to have certain offset load resistance, so the two hinged oil cylinders for multiselect of taking blame for others before dumping car, but two hinge oil cylinders are many one-level cylinder barrel, cost has increased a lot, is contrary to the principle of market economy, unfavorable to product market competition.In addition, these two kinds of oil cylinders, in order to guarantee high pressure sealing performance, adopt the sealing of two-stage Y-shaped ring more, the sealing means that one-level dust ring is dustproof, and this has just caused low pressure seal performance bad, in low pressure situation, situation about revealing easily occurs.
Model utility content
For existing practical problem in above-mentioned, the utility model provides a kind of multistage pair of hinge upside-down oil cylinder.
The utility model is achieved by the following technical solution: a kind of multistage pair of hinge upside-down oil cylinder, and it comprises: base cylinder assembly, cylinder barrel assembly at different levels, piston-rod assembly, cylinder bottom assembly and black box; Described black box comprises a dust ring and two y-type seal rings; Described base cylinder assembly comprises base cylinder, is fixed on hold-down ring and base cylinder hinged block on base cylinder, also comprises the base cylinder hinge being arranged on base cylinder hinged block; Described piston-rod assembly comprises piston rod and is arranged on the piston rod hinge of piston rod end; Described base cylinder hinge and compartment are hinged, and piston rod hinge and vehicle frame are hinged; Between base cylinder hinged block and base cylinder hinge, be that sphere connects; Described piston rod comprises a hollow circuit cylinder cylinder, be fixed on the bottom of cylindrical drum one end and be fixed on the outer end cap of the cylindrical drum the other end; On described outer end cap, be provided with cannulated threaded post, in screw column, offer filler opening; In described piston rod inside, be provided with oil pipe, oil pipe one end connects filler opening, and the oil pipe the other end passes bottom and is fixed on bottom; Described piston rod hinge center has step hole, and piston rod hinge is arranged on outer end cap by the macropore in step hole and the self-locking nut cooperation being located in screw column.
It is further: described bottom is fixed with welding manner and oil pipe.
Between described piston rod hinge and self-locking nut, be provided with check washer.
The utility model adopts two hinge installation forms, and compartment is to be all connected with oil cylinder by hinge with vehicle frame, and stressing conditions is good; By inverted structure, design, i.e. during oil cylinder lifting, cylinder diameter is larger,, has omitted first class of protection cylinder more in the above, has reduced cost of production.Adopt the sealing of two-stage Y-shaped ring, the sealing means that one-level dust ring is dustproof, the high pressure sealing performance of assurance oil cylinder, the opening up installation of y-type seal ring, even if make in low pressure situation, seal area also has pressure to exist, and guarantees low pressure seal performance.
The utility model is safe, economical, and good seal performance had both guaranteed the offset load resistance of oil cylinder, reduced again the cost of production of oil cylinder.
