Abstract
A booster spring auxiliary system for an excavator or a loader comprises a gas spring and an energy accumulator, wherein the gas spring is mounted between a large arm and a frame of the excavator or loader, the energy accumulator is connected to the gas spring via a gas pipe, and two ends of the gas spring are rotatably connected to the large arm and the frame respectively. When the excavator or loader is in operation, kinetic energy of the large arm during descending by relying on self gravity is converted into pressure to be accumulated in the energy accumulator by means of compression of the gas spring, and then the accumulated energy is released by the gas spring when the large arm ascends to assist a driving oil cylinder to ascend, so that the self gravity of the large arm, the self gravity of a small arm and the self gravity of a bucket are balanced, actual power output of an engine is decreased, energy consumption can be effectively lowered, pollution of fuel oil exhaust gas to the atmosphere is reduced, and the booster spring auxiliary system for the excavator or loader is more energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of power assist system that is used for excavator or loader, particularly a kind of power assistant spring accessory system that is used for excavator or loader.
Background technology
At present; The equipment of existing excavator, loader is by big arm, forearm, hinged the forming of scraper bowl three parts; Between said big arm and the frame, between big arm and the forearm, all be connected with between forearm and the scraper bowl and be used to drive the driving oil cylinder that big arm rises and falls, forearm flexible and scraper bowl rotates, said driving oil cylinder is connected in motor.Excavator or loader are in the actual job process; Because the own wt of whole big arm, forearm, scraper bowl, oil cylinder and associated components and the excavation weight of material in the scraper bowl; Rise and fall at big arm, forearm is flexible and scraper bowl rotation operation process; During particularly big arm lifting operation, need a large amount of power of consumption of engine, and these power consumptions in fact major part be created in the self gravitation lifting process to big arm, forearm and scraper bowl; Cause unnecessary energy consumption, increased of the pollution of fuel oil waste gas simultaneously atmosphere.
The utility model content
The main purpose of the utility model is the shortcoming that overcomes prior art, provides a kind of and can effectively reduce energy consumption, reduces the pollution of fuel oil waste gas to atmosphere, more the power assistant spring accessory system that is used for excavator or loader of energy-conserving and environment-protective.
The utility model adopts following technical scheme:
A kind of power assistant spring accessory system that is used for excavator or loader; This power assistant spring accessory system includes the big arm and the gas spring between the frame that are installed in excavator or loader and reaches the accumulator that is connected in gas spring by tracheae, and said gas spring two ends are rotationally connected with respectively on said big arm and the frame.
Said gas spring is the lockable gas spring, which is provided with the gas outlet.
Said accumulator is the air filling type accumulator.
Said tracheae two ends connect the gas outlet of gas spring and the air inlet port of accumulator respectively.
Can know that by above-mentioned description compared with prior art, the beneficial effect of the utility model is: can be when excavator or loader work to the utility model; Rely on the kinetic energy in the self gravitation decline process to become pressure to store in accumulator on big arm, when big arm carries out the lifting operation, institute's accumulation of energy is discharged through gas spring then through gas spring being carried out compressing and converting; The process auxiliary drive oil cylinder is done the lifting action; With the self gravitation of the big arm of balance, forearm and scraper bowl, reach the effect that reduces the output of motor actual power, can effectively reduce energy consumption; Reduce of the pollution of fuel oil waste gas, energy-conserving and environment-protective more to atmosphere.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model specific embodiment.
Among the figure: 1. big arm, 2. frame, 3. gas spring, 4. tracheae, 5. accumulator, 6. driving oil cylinder, 7. forearm, 8. scraper bowl.
The specific embodiment
Below the utility model is done further to describe through the specific embodiment.
With reference to Fig. 1; A kind of power assistant spring accessory system that is used for excavator or loader of the utility model; This power assistant spring accessory system includes the big arm 1 and the gas spring between the frame 23 that are installed in excavator or loader and reaches the accumulator 5 that is connected in gas spring 3 by tracheae 4, and said gas spring 3 two ends are rotationally connected with respectively on said big arm 1 and the frame 2.Said gas spring 3 is the lockable gas spring, which is provided with the gas outlet.Said accumulator 5 is the air filling type accumulator.Said tracheae 4 two ends connect the gas outlet of gas spring 3 and the air inlet port of accumulator 5 respectively.
With reference to Fig. 1, the utility model can rely on the kinetic energy in the self gravitation decline process to become pressure to store in accumulator 5 through gas spring 3 being carried out compressing and converting on big arm 1 when excavator or loader work; Then when big arm 1 carries out the lifting operation; Institute's accumulation of energy is discharged through gas spring 3, and process auxiliary drive oil cylinder 6 is done the lifting action, with the self gravitation of the big arm of balance 1, forearm 7 and scraper bowl 8; Reach the effect that reduces the output of motor actual power; Can effectively reduce energy consumption, reduce of the pollution of fuel oil waste gas, energy-conserving and environment-protective more atmosphere.
With reference to Fig. 1, when excavator was not installed the power assistant spring accessory system of the utility model, in forearm 7 plumbness, during scraper bowl 8 zero loads, driving oil cylinder 6 pressure of the big arm 1 that hoists need reach 90 kilograms; In forearm 7 plumbness, scraper bowl 8 full loads, driving oil cylinder 6 pressure of the big arm 1 that hoists need reach 130 kilograms.After the power assistant spring accessory system of installing the utility model, in forearm 7 plumbness, during scraper bowl 8 zero loads, driving oil cylinder 6 pressure of the big arm 1 that hoists only need reach 10 kilograms; In forearm 7 plumbness, scraper bowl 8 full loads, driving oil cylinder 6 pressure of the big arm 1 that hoists only need reach 50 kilograms.
The above-mentioned specific embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
