Description
Technical field
The present invention relates to transporting equipment field, more particularly to a kind of dual-purpose hydraulic system for dumper.
Background technology
At present, the hydraulic system of dumper carries out inclination wagon box using unidirectional oil cylinder, and unidirectional oil cylinder is placed in the front of wagon box
Or centre position, self gravitation is relied on when wagon box falls and is pressed downward unidirectional oil cylinder to set back, when having air in unidirectional oil cylinder
When, wagon box can be caused to hurtle down suddenly, cause unstable, be easily damaged hydraulic system.And traditional dumper is unloaded
During operation, by manual control oil pump, due to oil pump and fuel tank Integral design, frequent operation can damage fuel tank, cause oil leak, and
Oil pump is located at driver's seat rear, operation inconvenience.
The content of the invention
The defects of present invention is in order to make up prior art, there is provided a kind of reasonable in design, easy to use is used for certainly
The dual-purpose hydraulic system unloaded.
The present invention is achieved through the following technical solutions：
A kind of dual-purpose hydraulic system for dumper, it is characterised in that：Oil pump, oil including being fixed on vehicle body side
Case and the hydraulic jack installed in bottom bracket rear, the hydraulic cylinder piston rod top are fixed with wagon box rear end, institute
State and fixed seat is also equipped with bottom bracket, installation control valve body in the fixed seat, described control is provided with valve body
Inlet valve I, delivery valve I, delivery valve II, inlet valve II, the oil pump are connected by feed line I with inlet valve I, delivery valve I
It is connected by feed line II with the oil inlet of hydraulic jack, the oil-out of hydraulic jack passes through oil return pipeline II and inlet valve II
Connection, the delivery valve II are connected by oil return pipeline I with oil pump, and the valve element of the control valve body is connected by bracing wire and handle
Connect.
Further, the stability for increase hydraulic jack when falling after rise, and be easy to jack up wagon box at rear, it is described
Hydraulic jack is double loop hydraulic oil cylinder, and handle adjustment control valve body realizes rising and falling for oil cylinder, completes rising and falling for wagon box.
The handle is preposition on the right side of the driver's seat of vehicle body, convenient operation.
The beneficial effects of the invention are as follows：The dual-purpose hydraulic system for dumper of the present invention, compact-sized, design is closed
Reason, realizes rising and falling for oil cylinder by handle adjustment control valve body, completes rising and falling for wagon box, it is possible to achieve the stabilization of wagon box is returned
Fall, and convenient operation, control valve body and hydraulic jack position compact, reduce the inefficient length of oil circuit, suitable for promoting the use of.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is a kind of structural representation of dual-purpose hydraulic system for dumper of the invention；
Accompanying drawing 2 is a kind of structural representation of the bottom bracket of dual-purpose hydraulic system for dumper of the invention；
Accompanying drawing 3 is a kind of structural representation of the control valve body of dual-purpose hydraulic system for dumper of the invention.
In figure, 6, bottom bracket, 7 wagon boxes, 8 vehicle bodies, 9 hydraulic jacks, 10 bracing wires, 11 handles, 12 fixed seats, 13 controls
Valve body processed, 14 oil pumps, 15 fuel tanks, 16 feed lines I, 17 feed lines II, 18 oil return pipelines I, 19 oil return pipelines II, 20 enter
