The perspective view of the excavator that Fig. 1 provides for the embodiment of the present invention.
As it is shown in figure 1, the excavator that the present embodiment provides, including electromotor, hydraulic system, equipment, running gear
And electric control system, also include that Aeroassisted jacking device 1, Aeroassisted jacking device 1 are arranged at two of control large arm 3 lifting
Between hydraulic cylinder 2, and one end of Aeroassisted jacking device 1 connects large arm 3, and the other end is connected with the mounting seat 4 of hydraulic cylinder 2.
Aeroassisted jacking device 1 can be cylinder, as shown in Figure 1.
Selecting cylinder as Aeroassisted jacking device 1, response speed is fast, the action with hydraulic cylinder 2 almost without time difference,
Simple in construction, installation more convenient operation, and, because of the air-tightness that it is good, the performance of auxiliary hydraulic cylinder 2 work the most more has guarantor
Barrier, is more beneficial for saving the fuel oil of electromotor.
Between two hydraulic cylinders 2 controlling large arm 3 lifting, Aeroassisted jacking device 1 is set, Aeroassisted jacking device 1
One end connects large arm 3, and the mounting seat 4 of the other end and two hydraulic cylinders 2 connects.When needing operation large arm 3 to rise, by electrically
Control system controls the piston rod of two hydraulic cylinders 2 and stretches out, and along with the piston rod of hydraulic cylinder 2 stretches out, large arm 3 is propped, simultaneously
The piston rod of Aeroassisted jacking device 1 also obtain flexible space, and then stretches out, outside two hydraulic cylinder 2 shareds
Load；When needs operation large arm 3 is regained, the piston rod being controlled two hydraulic cylinders 2 by electric control system is regained, along with liquid
The piston rod of cylinder pressure 2 is regained, and large arm 3 is regained, and the piston rod of Aeroassisted jacking device 1 is at the gravity of large arm 3 and hydraulic cylinder 2 simultaneously
Piston rod regain power drive under regain.Aeroassisted jacking device 1 and two hydraulic cylinder 2 shared external loads, have
It is beneficial to reduce the power output of electromotor, and then saves fuel oil.Meanwhile, when large arm 3 is regained, in Aeroassisted jacking device
Gas is also pushed back, and remains subsequent work and recycles, it is possible to ensures the recycling of Aeroassisted jacking device 1.
On the basis of above-described embodiment, concrete, the cylinder body of Aeroassisted jacking device 1 is hinged with large arm 3, Aeroassisted
The piston rod of jacking device 1 is hinged with the mounting seat 4 of hydraulic cylinder 2.

Mounting seat 4 on installing space limited, and the distance between two hydraulic cylinders 2 is the biggest the closer to large arm 3, so, by gas
Cylinder is inverted and is allowed the cylinder part being relatively large in diameter be positioned at the large pitch of two hydraulic cylinders 2, can arrange cylinder diameter herein bigger
Cylinder, large arm 3 promote during, it is provided that bigger power.
On the basis of above-described embodiment, concrete, it is filled with nitrogen in Aeroassisted jacking device 1.
Filling nitrogen in Aeroassisted jacking device 1, during large arm 3 rises, can provide bigger by compressed nitrogen
Power, thus share the load of hydraulic cylinder 2 greatly, save more engine fuel oil.
On the basis of above-described embodiment, concrete, also include the first valve for controlling gas path on-off, the first valve
It is connected with the bottom of Aeroassisted jacking device 1.
In the course of normal operation of excavator, the first valve is in opening, when needs transport excavator, closes
First valve, cuts off the source of the gas of Aeroassisted jacking device 1, it is possible to prevent in the transportation of excavator, gases at high pressure (example
As, nitrogen) piston rod of Aeroassisted jacking device 1 is ejected, cause large arm 3 to be raised suddenly, so that anticipating in limit for height section
Outer situation occurs.
On the basis of above-described embodiment, concrete, also include gas reservoir, one end of the first valve connects Aeroassisted
Jacking device 1, the other end connects gas reservoir.
Can lay in more gases at high pressure by arranging gas reservoir, the action for Aeroassisted jacking device 1 provides more
Big motive force, thus share the load of hydraulic cylinder 2 greatly, save more engine fuel oil.
On the basis of above-described embodiment, concrete, the exit of gas reservoir is provided with the second valve.
By arranging the second valve in the exit of gas reservoir, when air-channel system needs maintenance, close the second valve,
Gas as much as possible can be sealed in gas reservoir, it is to avoid the waste of gas.
On the basis of above-described embodiment, concrete, the exit of gas reservoir is additionally provided with Pressure gauge.
By arranging Pressure gauge, people can understand the pressure state in gas reservoir, the pressure in gas reservoir at any time
When power is too low, timely make-up gas, discharge portion gas during hypertonia in time, make Aeroassisted jacking device 1 be in all the time
Good state, thus it is more beneficial for the saving of engine fuel oil.
On the basis of above-described embodiment, concrete, gas reservoir is two, and two gas reservoir are interconnected.
Gas reservoir can be one and can also arrange multiple gas reservoir can store more high pressure gas for multiple
Body, the action for Aeroassisted jacking device 1 provides bigger motive force, thus shares the load of hydraulic cylinder 2 greatly, joint
Save more engine fuel oil.
On the basis of above-described embodiment, concrete, also include counterweight 5, gas reservoir is arranged in counterweight 5.
Gas reservoir is arranged in counterweight 5, is conducive to increasing the weight of counterweight 5, it is possible to make in excavator work process
Counterbalance effect more preferable.
On the basis of above-described embodiment, concrete, also include case 6 is installed, case 6 is installed and is fixedly installed in counterweight 5, gas
Body storage tank is arranged in installation case 6.
Concrete, gas reservoir is fixedly installed in installation case 6.Gas reservoir is fixedly installed in installation case 6, makes gas
Body storage tank can be conducive to extending the service life of gas reservoir, it is ensured that gas reservoir from exposing to wind and rain or high temperature attack
Normal work.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, it is not intended to limit；To the greatest extent
The present invention has been described in detail by pipe with reference to foregoing embodiments, it will be understood by those within the art that: it depends on
So the technical scheme described in foregoing embodiments can be modified, or the most some or all of technical characteristic is entered
Row equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from various embodiments of the present invention technology
The scope of scheme.
