Abstract
The utility model discloses a front oil cylinder of an inversion dumper, relating to an accessory of an engineering vehicle, which is a multi-stage oil cylinder. The front oil cylinder comprises a cylinder body, a piston and an oil input/output hole. Furthermore, the front oil cylinder is an oil cylinder structure which is inversely used. A connection structure connected with the bottom of the front part of a carriage of the dumper is arranged at the lower part of the cylinder body. The oil input/output hole is arranged on the bottom surface of the piston. An oil hole is arranged in the piston. The connection structure is two first symmetrical pin shafts at two sides of the lower part of the cylinder body. According to the inversion oil cylinder disclosed by the utility model, the pin shafts connected with the bottom of the front part of the carriage are arranged at the lower part of the cylinder body; therefore, when the piston extends out, the front oil cylinder of the inversion dumper is not interfered with the carriage; furthermore, a sleeve structure is unnecessary to be arranged again; the length of the piston is reduced; materials are saved; and the cost is reduced.
Description
Technical field
The utility model relates to a kind of engineering truck accessory, the preposition oil cylinder of especially a kind of inversion type dumping car.
Background technology
Dumping car is a kind of engineering truck commonly used, for heavy and medium-sized dumping car, often uses preposition oil cylinder to realize the self-unloading of tumbling in compartment.The preposition oil cylinder of the first generation is a kind of multi-stage oil cylinder, is connected through the hinge its piston tip on the top of front portion, compartment.This mounting means stretches out at piston and is prone to take place the interference of oil cylinder with the compartment to the carriage top time-out, needs design to stretch out more piston Connection Block, takies than large space, has reduced the volume in compartment.The preposition oil cylinder of the second generation has designed a sleeve that is connected with oil cylinder piston for multi-stage oil cylinder; The bottom of sleeve is connected through the hinge with anterior bottom, compartment; Solved when piston stretches out oil cylinder with the interference problem at rear portion, compartment; Increased the volume in compartment, and said sleeve can cover piston together with cylinder body in the lump during piston-retraction, makes the compartment can return to level attitude.But this design has increased tube-in-tube structure, and the weight of this sleeve accounts for 20% of whole preposition oil cylinder, means to have increased 20% cost.
The utility model content
The technical matters that the utility model will solve provides the preposition oil cylinder of a kind of inversion type dumping car with low cost.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: it is a multi-stage oil cylinder; Comprise cylinder body, piston and oil inlet and outlet, and be a kind of cylinder structure of being inverted use, be provided with in the bottom of its cylinder body can with the anterior bottom of body of tipper carriage pivotally attached connection structure.
Said oil inlet and outlet is arranged on the bottom surface of piston, and oilhole is set in piston.
Said connection structure is the bearing pin one that is positioned at two symmetries of inferior part of the cylinder block both sides.
Said piston base is provided with the connector that can be connected with dumping car upper piston Connection Block, its with piston through being threaded, be connected with two bearing pins two of said Connection Block through symmetry.
Said lower part of piston is a step axle construction, and shaft extension is provided with outside thread, is provided with through hole at said connector, has externally threaded shaft extension and passes through hole and fix with nut; Between the shaft shoulder and connector of step axle, and be provided with cushion rubber between nut and the connector.
Said connection structure also can be a bearing pin that is positioned at inferior part of the cylinder block.
Adopt the beneficial effect that technique scheme produced to be: to be inverted the oil cylinder that uses; The bearing pin that is connected with anterior bottom, compartment is arranged at the bottom of cylinder body; The preposition oil cylinder of said a kind of inversion type dumping car can not interfere with the compartment when piston was stretched out, and did not need tube-in-tube structure is set again, and had reduced the length of piston; Saving in material has reduced cost.Oilhole is set in piston, has simplified tubing system, be convenient to the structure design of car load.The connector structure of piston base has strengthened the strength and stiffness at this position.Cushion rubber is set, the stability when having improved the preposition cylinder action of said a kind of inversion type dumping car in connector.
