Description
Technical field
This utility model is related to a kind of recharging oil device of hydraulic motor, specifically a kind of hydraulic pressure reclaimed with rotation energy
Excavator rotary motor oil-supplementing system.
Background technology
Hydraulic crawler excavator turns round stopped process, and the high pressure by rotary motor oil-out is braked, and now rotary motor goes out
Mouthful high pressure kicks, import low pressure repairing, high pressure kicks flow some entrance low pressure repairing.The low-pressure side repairing of rotary motor
Flow in addition to from high-pressure side excess flow, at some total oil return from excavator hydraulic system.Xu works group digs
The hydraulic hybrid power-saving technology of the national science and technology supporting plan-based on excavator energy regenerating that pick Machinery Co., Ltd. undertakes
Research and application（Project number：2015BAF07B06）, the rotation energy recovery technology of excavator is studied, excavator is being turned round
After energy is reclaimed, high pressure kicks flow no longer to low pressure repairing, under some conditions at the total oil return of excavator hydraulic system
Flow can not meet the traffic demand of rotary motor low-pressure side, when can cause repairing deficiency rotary braking, motor is emptied, and reduces
Motor life.On the other hand, rotary motor repairing needs certain pressure, it is impossible to the directly repairing from fuel tank, therefore for having
The hydraulic crawler excavator that rotation energy is reclaimed needs special repairing source.
As shown in figure 1, conventional excavator revolution repairing is from the first revolution overflow valve 4 or the second revolution 5 overflow of overflow valve
Flow, while also from repairing before excavator hydraulic system return oil pressure valve 7.Excavator rotary braking energy is reclaimed
Afterwards, the first revolution overflow valve 4 and second turns round overflow valve 5 without excess flow, because excavator hydraulic system oil return is unstable
Fixed, the repairing underfed being likely to result in from before return oil pressure valve 7 causes rotary motor 6 to be emptied, and reduces by 6 longevity of rotary motor
Life.
Content of the invention
For the problem that above-mentioned prior art is present, this utility model provides a kind of hydraulic pressure digging that reclaims with rotation energy
Pick machine rotary motor oil-supplementing system, system additionally do not consume the energy and flow of excavator hydraulic system, do not affect excavator each
The performance of element, it is adaptable to the hydraulic crawler excavator system that rotation energy is reclaimed.
To achieve these goals, the technical solution adopted in the utility model is：A kind of liquid reclaimed with rotation energy
Pressure excavator rotary motor oil-supplementing system, including main-control valve of excavating machine, first revolution overflow valve, second revolution overflow valve, first
Repairing check valve, the second repairing check valve, rotary motor return oil pressure valve；Check valve and accumulator；The main-control valve of excavating machine
Oil return T mouths take back oily counterbalance valve import, and the import of return oil pressure valve connects check valve inlet simultaneously, and one-way valved outlet connects accumulator and enters
Mouthful, accumulator import connects the first repairing check valve and the second repairing check valve inlet simultaneously, and the first repairing check valve and second is mended
Oily one-way valved outlet connects rotary motor oil inlet and outlet respectively.
This utility model is further, and the accumulator is provided with precompression, and precompression is required more than or equal to rotary motor
Oil compensation pressure.
This utility model is further, and the minimum oil reserve of the accumulator turns round 180 ° of braking institutes more than or equal to excavator
Need the repairing amount of rotary motor.
The invention has the beneficial effects as follows：
1st, at the total oil return of excavator, pressure flow is unstable, when storing that the big pressure of flow is big at total oil return using accumulator
Fluid, for rotary motor repairing during the excavator rotary braking for having rotation energy to reclaim, system does not additionally increase energy
Consume, do not affect main system flow, simply, energy-conservation.
2nd, the repairing function to rotary motor is realized, prevents motor to be emptied damage, the excavation to reclaiming with rotation energy
Machine is especially suitable.
3rd, the present invention need not detect that related pressure, related elements are worked automatically, without the need for additional control system.
Description of the drawings
Fig. 1 is excavator rotary system principle；
Fig. 2 is this utility model hydraulic schematic diagram；
In figure：1st, main-control valve of excavating machine, the 2, first revolution overflow valve, the 3, second revolution overflow valve, the 4, first repairing are unidirectional
Valve, the 5, second repairing check valve, 6, rotary motor, 7, return oil pressure valve, 8, check valve, 9, accumulator.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 2 this utility model has the hydraulic crawler excavator rotary motor oil-supplementing system that rotation energy is reclaimed, including
The revolution revolution overflow valve 3 of overflow valve 2, second of main-control valve of excavating machine 1, first, the first repairing check valve 4, the second repairing check valve
5th, 6 return oil pressure valve 7 of rotary motor；Check valve 8 and accumulator 9；1 oil return T mouths of main-control valve of excavating machine take back oily counterbalance valve 7 and enter
Mouthful, 7 import of return oil pressure valve connects 8 import of check valve simultaneously, and the outlet of check valve 8 connects 9 import of accumulator, and 9 import of accumulator is simultaneously
Connect 5 import of the first repairing check valve 4 and the second repairing check valve, the first repairing check valve 4 and the outlet point of the second repairing check valve 5
Rotary motor 6 oil inlet and outlet is not connect.
Wherein accumulator 9 is provided with precompression, and precompression is more than or equal to the oil compensation pressure that rotary motor 6 is required.Accumulator 9
Minimum oil reserve turns round the repairing amount of rotary motor 6 needed for 180 ° of brakings more than or equal to excavator.
The characteristics of this utility model has certain back pressure using the total oil return of excavator hydraulic system, carries out the storage of repairing fluid
And release.After system adds check valve 8 and accumulator 9, can be when excavator return flow be big, by accumulator
9 storage part fluid.During reduced pressure before return oil pressure valve 7, because of the effect of check valve 8, the fluid of accumulator 9 will not
Flow out from return oil pressure valve 7.When excavator has rotation energy to reclaim, the first revolution overflow valve 4 and the second revolution overflow valve 5 do not have
There is excess flow, when the total oil return of excavator hydraulic system is again not enough, the fluid of accumulator 9 passes through the first repairing check valve 4 or the
Two repairing check valve 5 enters rotary motor 6 and carries out repairing, prevents rotary motor 6 to be emptied.
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and on this basis may be used
Make according to actual needs having and targetedly adjust, so as to obtain different embodiments.Due to mode in the cards compared with
Many, just no longer illustrate one by one here.
