Abstract
The invention relates to the technical field of extension devices, in particular to a dump truck extension device comprising a fixed pump head and a connecting base forming a pump with the fixed pump head. The fixed pump head is provided with two opposite first installation holes, the connecting base is provided with two opposite second installation holes, and the straight line where the center points of the two first installation holes located is perpendicular to that where the center points of the two second installation holes located; a crossed connector is arranged in the internal space of the pump formed through the fixed pump head and the connecting base and is connected to the two first installation holes of the fixed pump head and the two second installation holes of the connecting base through four connecting sleeves. According to the device, when the oil pump operates, the piston rod presses a car outwardly and stably, and the purpose of unloading goods from the car can be achieved.
Description
Technical field
The present invention relates to the technical field of stretching device, especially a kind of tip lorry stretches device with rising.
Background technology
Tip lorry is the vehicle of the tipping short distance convey materials of a kind of special hopper.Vehicle body is provided with " bucket " shape container, can overturns to facilitate unloading.Work one of vitals when stretching device in tip lorry, goods is outwards toppled in the compartment that it is directly used in control tip lorry, but rising of existing tip lorry is stretched device and structurally be there is certain deficiency, rise and stretch piston rod in device when compartment, top, what normal appearance was slided manifests, easily cause piston rod to exert a force unstable, and make compartment be forced to get back to initial position instantaneously, be also just present in very large security hidden trouble.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposed in above-mentioned background technology, the invention provides a kind of tip lorry and stretch device with rising, operation of oil pump, piston rod can very firm pushing up compartment outward, to reach the object of the goods unloading in compartment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tip lorry stretches device with rising, comprise fixing pump head and synthesize the connection base of the pump housing with fixed pump head group, fixing pump head offers two the first mounting holes be oppositely arranged, connect on base and offer two the second mounting holes be oppositely arranged, the center-point place straight line of the center-point place straight line of two the first mounting holes and two the second mounting holes is perpendicular, fixing pump head is provided with cross connecting piece with the inner space being connected the pump housing that base is formed, cross connecting piece is connected with two the second mounting holes be connected on base with the first mounting hole of two on fixing pump head respectively by four coupling bushs.
Further restriction: fixing pump head is plugged with piston rod with the inner space being connected the pump housing that base is formed.
Further restriction: fixing pump head be connected base and be U-shaped structure.
Beneficial effect of the present invention: this tip lorry stretches device with rising, because fixing pump head is provided with the inner space being connected the pump housing that base is formed the cross connecting piece be connected with the pump housing, make the steadiness of the piston rod be inserted in the pump housing strong, work as operation of oil pump, piston rod will very firm pushing up compartment outward, to reach the object of the goods unloading in compartment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is decomposition texture schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
In figure: 1, fixing pump head, 2, connect base, the 3, first mounting hole, the 4, second mounting hole, 5, cross connecting piece, 6, coupling bush.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Tip lorry as depicted in figs. 1 and 2 stretches device with rising, comprise fixing pump head 1 and be combined into the connection base 2 of the pump housing with fixing pump head 1, fixing pump head 1 offers two the first mounting holes 3 be oppositely arranged, connect on base 2 and offer two the second mounting holes 4 be oppositely arranged, the center-point place straight line of two the first mounting holes 3 and the center-point place straight line of two the second mounting holes 4 perpendicular, fixing pump head 1 is provided with cross connecting piece 5 with the inner space being connected the pump housing that base 2 is formed, cross connecting piece 5 is connected with two the second mounting holes 4 be connected on base 2 with two the first mounting holes 3 on fixing pump head 1 respectively by four coupling bushs 6.
Wherein fix pump head 1 and be plugged with piston rod with the inner space being connected the pump housing that base 2 is formed.Fixing pump head 1 be connected base 2 and be U-shaped structure.
This tip lorry stretches device with rising, because fixing pump head 1 and the inner space being connected the pump housing that base 2 is formed are provided with the cross connecting piece 5 be connected with the pump housing, make the steadiness of the piston rod be inserted in the pump housing strong, work as operation of oil pump, piston rod will very firm pushing up compartment outward, to reach the object of the goods unloading in compartment.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine its technical scope according to right.
