Description
Technical field
The utility model relates to a kind of new type power accessory system for excavator or loader.
Background technology
At present, the equipment of existing excavator or loader is by large arm, forearm, hinged the forming of scraper bowl three parts, between described large arm and frame, between large arm and forearm, be all connected with the driving oil cylinder that large arm rises and falls for driving, forearm flexible and scraper bowl rotates between forearm and scraper bowl, described driving oil cylinder is connected in motor.Excavator or loader are in actual job process, due to the own wt of whole large arm, forearm, scraper bowl, oil cylinder and associated components and the excavation weight of material in scraper bowl, at large arm, rise and fall, forearm is flexible and scraper bowl rotation operation process, particularly during large 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 of large arm, forearm and scraper bowl, cause unnecessary energy consumption, increased the pollution of fuel-oil waste-gas to atmosphere simultaneously.Therefore, in prior art, occurred again setting up gas-loaded accumulator between a kind of large arm at excavator or loader and frame, pressure with compression when declining stores in accumulator, then when large arm carries out lifting operation, institute's accumulation of energy is discharged, assistive drive oil cylinder is done lifting action, with the large arm of balance, the self gravitation of forearm and scraper bowl, reach the effect that reduces the output of motor actual power, but, the excavator of this kind of structure or loader, because joint exists gap, therefore when work, there is transition, the process of being interrupted, and due to complex structure, assembling process is also more complicated.
Utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, and a kind of energy-conserving and environment-protective are provided, and designs simplification is easy to assembly, and the good new type power accessory system for excavator or loader of work continuity.
The utility model adopts following technical scheme:
A kind of new type power accessory system for excavator or loader, include large arm and the energy storage oil cylinder between frame that is connected in excavator or loader and the accumulator that is connected in this energy storage oil cylinder, described energy storage oil cylinder consists of the power-assisted cylinder barrel that a master cylinder and is fixed on this main oil cylinder piston bar and sealing shroud is located at outside this master cylinder, on described power-assisted cylinder barrel, offer servo-cylinder hydraulic fluid port, described accumulator is connected in this servo-cylinder hydraulic fluid port by oil pipe.
Further, described energy storage oil cylinder two ends are articulated with respectively on the large arm and frame of excavator or loader.
Further, described power-assisted cylinder barrel and master cylinder cylinder barrel oppositely arrange, and can along the sealing of master cylinder cylinder barrel outer wall, slide with main oil cylinder piston bar is flexible.
Further, on the piston rod of described master cylinder, offer the decline hydraulic fluid port of a connection master cylinder cylinder barrel inside, on master cylinder cylinder barrel, offer the rising hydraulic fluid port that is communicated in master cylinder cylinder barrel inside.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are: the gas spring of gas-loaded accumulator of the prior art is combined as a whole with driving oil cylinder, it is energy storage oil cylinder of the present utility model, can be when excavator or loader work, by energy storage oil cylinder, converting the kinetic energy in large arm dependence self gravitation decline process to pressure stores in accumulator, then when large arm carries out lifting operation, institute's accumulation of energy is discharged, auxiliary large arm lifting action, with the large arm of balance, the self gravitation of forearm and scraper bowl, reach the effect that reduces the output of motor actual power, can effectively reduce energy consumption, reduce the pollution of fuel-oil waste-gas to atmosphere, energy-conserving and environment-protective more, simultaneously, structure is simplified more, easy to assembly, and can solve when work, there is transition, the problem of being interrupted, work continuity is better.
