Description
Technical field
The utility model belongs to technical field of engineering machinery, particularly relates to a kind of engineering machinery and uses the hydraulic oil sink.
Background technique
At present, low-carbon (LC), environment protection novel are just in the ascendant in the application of engineering machinery transmission, and the exploitation energy-conserving and environment-protective become trend and direction.Hydraulic oil radiator is used in on the engineering machinery of hydraulic oil as the power transmission medium, is installed on the loop of hydraulic system.During work, high temperature oil stream is through hydraulic oil cooling device in the hydraulic system, and the cool air with forced flow in heat exchanger carries out efficient heat exchange, and oily temperature drop to operating temperature can be run well to guarantee main frame continuously, and work can be carried out smoothly.Existing hydraulic oil radiator is installed on propons and drives the grader Operation System, and this propons drives grader and selects BBG for use, and what itself was equipped with is the water, oil, gas combined heat radiators.Because three radiation systems of this radiator all are utilized; And this grader has increased propons driving hydraulic system; When the propons drive motor is worked; Hydraulic oil can produce very high heat, and the combined heat radiator that driven by engine blower this moment can't satisfy the heat radiation of Operation System hydraulic oil owing to structure, space problem.
Summary of the invention
The technical problem of the utility model for existing in the solution known technology, and provide a kind of engineering machinery to use the hydraulic oil sink.
The purpose of the utility model provides a kind ofly to be had simple in structurely, and by use condition heat radiation, energy-efficient performance is good, easy for installation, characteristics such as transmission efficiency height, and the engineering machinery that can be widely used in discontinuous use engineering mechanical device heat radiation is used the hydraulic oil sink.
The utility model select for use one independently sink be the heat radiation of Operation System hydraulic oil; Grader is with the work that is cascaded of sink and operation hydraulic system; The control valve return opening links with radiator, and another outlet of radiator links to each other with the oil return piece, like this; The hydraulic oil of operation hydraulic system is directly got back to fuel tank behind radiator heat-dissipation, circulation is utilized by each hydraulic system.The fan of this radiator is controlled with relay, has only when the propons drive motor is worked and can give an one of which trigger signal, and fan just turns round; On the contrary, when the propons drive motor was not worked, radiator fan did not turn round; Hydraulic oil is directly got back to fuel tank through radiator, has characteristics energy-conservation, controllability, and traditional radiator is no matter whether hydraulic oil needs; All dispel the heat, increase unnecessary power consumpiton.
The utility model grader is used sink, and self-existent hydraulic oil radiator does not promptly use the driving energy of engine blower, accomplishes the heat radiation to Operation System hydraulic oil by electrical system control.
The technological scheme that the utility model grader uses the hydraulic oil sink to be taked for solution propons driving grader Operation System hydraulic oil heat dissipation problem is:
A kind of engineering machinery is used the hydraulic oil sink; Be characterized in: the hydraulic oil sink comprises radiator, fuel tank, controller, oil hydraulic pump and scavenger valve; Oil hydraulic pump connects the fuel tank oil suction, and the oil hydraulic pump fuel feeding is given the engineer machinery operation hydraulic system, and operation hydraulic system return line links to each other with radiator; Hydraulic oil entering scavenger valve through radiator heat-dissipation comes out is got back to fuel tank, thereby makes the heat radiation of operation hydraulic system hydraulic oil; Controller connects the control radiator fan.
The utility model grader can also adopt following technical measures with the hydraulic oil sink:
Described engineering machinery is used the hydraulic oil sink, is characterized in: oil hydraulic pump is installed on the construction machinery gear box power taking mouth.
Described engineering machinery is used the hydraulic oil sink, is characterized in: controller is a relay control mode, and engineering machinery has the propons drive motor, gives the relay trigger signal during work of propons drive motor, and relay power supply control radiator fan rotates heat radiation.
Advantage and the good effect that the utlity model has are:
Grader with sink owing to adopted the utility model brand-new technology scheme, compared with prior art simple in structure, dispel the heat according to use condition, solved the heat dissipation problem that propons drives grader Operation System hydraulic oil.This radiator is independent of combined heat radiator and exists; Assigning a work when having simplified the grader design; And this heat sink applications is behind product; Because its automation control makes the Operation System hydraulic oil temperature reduce to operating temperature and can run well continuously to guarantee main frame, grader work can be carried out smoothly.
It is good, easy for installation to the utlity model has energy-efficient performance, and the transmission efficiency advantages of higher can be applied to the heat radiation of the engineering mechanical device of any discontinuous use.

Embodiment
For further understanding technology contents, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Engineering machinery is used the hydraulic oil sink, comprises radiator, fuel tank, controller, oil hydraulic pump and scavenger valve.Oil hydraulic pump is installed on the construction machinery gear box power taking mouth; Oil hydraulic pump connects the fuel tank oil suction; The oil hydraulic pump fuel feeding is given the engineer machinery operation hydraulic system; Operation hydraulic system return line links to each other with radiator, gets back to fuel tank through the hydraulic oil entering scavenger valve that radiator heat-dissipation comes out, thereby makes the heat radiation of operation hydraulic system hydraulic oil; Controller connects the control radiator fan.Controller is a relay control mode, gives the relay trigger signal during work of engineering machinery propons drive motor, and relay power supply control radiator fan rotates heat radiation.
Concrete structure of the utility model and working procedure thereof:
Engineering machinery is used the hydraulic oil sink, comprises control valve 1, oil hydraulic pump 2, hydraulic oil container 3, oil return piece 4, gearbox 5, hydraulic oil radiator 6.This system docks through motor and gearbox, the realization energy transfer, and the operation pump is installed on the gearbox power taking mouth, and during work, the operation pump pumps from the hydraulic oil container oil suction, gives two loops respectively.In these two loops, the flow of oil is identical.When control valve during at meta, hydraulic oil is got back to fuel tank through back oil road, oil return piece, hydraulic oil radiator.
When moving one or two operating handle, the one-way valve that hydraulic oil is opened in the control valve gets into corresponding oil hydraulic cylinder or oil hydraulic motor.The effect of one-way valve is that the oil of restraint of labour device flows backwards to fuel tank, to guarantee the proper functioning of hydraulic system.Be installed in the bidirectional hydraulic lock on perching knife inclination, two perching knife up-downs and the back ridge buster loop, can prevent because the displacement that weight of equipment own and load are caused has guaranteed traffic safety and perching knife homework precision.About two hoist cylinders because by two loop fuel feeding that wait flow, therefore, the up-down of two hoist cylinders has realized synchronously and with speed, so improved the working performance of grader basically.
Because the used hydraulic oil of drive system was from hydraulic oil container before propons drove grader; And have only when the propons drive motor is worked; The hydraulic oil radiator fan just can turn round automatically, and hydraulic oil flow cools off through radiator automatically, and this has just reached the purpose of giving its hydraulic oil heat radiation when the forerunner works.
