Description
Technical field the utility model relates to a kind of aerial platform, relates in particular to a kind of balancing device of aerial platform.
The effect of background technology aerial platform balancing device is to guarantee that the aerial platform working arm in amplitude changing process, makes manned work bucket be maintained fixed angle with ground all the time.Though the common mechanical balance device structure is simple, but when the aerial platform that is used to telescopic arm structure, in the telescopic boom liter falls process, can not make manned work bucket and ground keep angle constant, limited the change angle scope of telescopic boom, so the common mechanical balancing device can not be applied to the aerial platform with telescopic arm structure.
The summary of the invention the purpose of this utility model is in order to overcome the defective of above-mentioned mechanical equilibrator, provide a kind of be applied to telescopic arm structure aerial platform, and can make telescopic boom change angle scope reach 0-180 ° mechanical equilibrator.
The purpose of this utility model is achieved through the following technical solutions: a kind of balancing device of aerial platform, comprise each identical runner of diameter, soft rope 7 and hydraulic ram 1,4, the oil cylinder of first hydraulic ram 1 is hinged on the turntable, and its plunger is hinged on the principal arm; The oil cylinder of second hydraulic ram 4 is located in the principal arm 2, and its plunger head stretches in the corresponding slideway 6 that is fixed in the principal arm 2, and plunger top is connected with pipe link 5 one ends; First hydraulic ram, 1 big chamber links to each other with second hydraulic ram, 4 big chambeies, and first hydraulic ram, 1 loculus links to each other with second hydraulic ram, 4 loculuses; First runner 3 is fixed between the oil cylinder of principal arm 2 inner arms and second hydraulic ram 4; Second runner 8 is fixed in the telescopic boom 9, principal arm and telescopic boom hinged place; The 3rd runner 10 is fixed in the telescopic boom 9, second runner, 8 belows; The 4th runner 11 is fixed on the top, lower end of telescopic boom 9; Be wound with soft rope 7 on each runner, an end of soft rope 7 is connected with pipe link 5 free ends, and the other end is fixed on the 4th runner 11; First runner 3, second runner 8 and the 4th runner 11 turn to identical, the 3rd runner 10 and second runner, 8 switched in opposite.
Described runner is sprocket wheel or pulley, and described soft rope can be chain or steel rope.
Principle of work of the present utility model is as follows: when principal arm 2 liftings, work bucket 12 can rotate thereupon and take turns 11 upwards inclinations, principal arm 2 drives oil cylinder 1 and stretches out, because oil cylinder 1,4 big chambeies link to each other with big chamber, loculus links to each other with loculus, when oil cylinder 1 stretches out, the oil that its loculus is forced out enters the loculus of oil cylinder 4, make the withdrawal of oil cylinder 4 cylinder bars, loosen chain 7 during oil cylinder 4 withdrawals, work bucket 12 is under the deadweight effect, and the wheel 11 that rotates is downward-sloping, compensation work bucket 12 makes between work bucket 12 and ground angle constant because the angle that principal arm 2 elevate a turnable ladders produce changes.When principal arm fell, work bucket 12 rotated thereupon and takes turns 11 downward inclinations.At this moment, 1 withdrawal of principal arm compressing oil cylinder, the oil in oil cylinder 1 big chamber is forced out, and the oil that is forced out enters the big chamber of oil cylinder 4, and oil cylinder 4 cylinder bars are stretched out, tension chain 7 when oil cylinder 4 stretches out, chain 7 drives sprocket wheel 11 left-hand revolutions, and work bucket 12 produces the wheel 11 acclivitous motions that rotate with sprocket wheel 11 rotations, compensation the downward-sloping of generation because principal arm falls realizes that angle is constant between work bucket 12 and ground.
When folding arm lifting or whereabouts, the sprocket wheel that is made of chain 7, sprocket wheel 8,10,11 among the figure, link chain mechanism can be realized the equilibrium function of work bucket fully.When folding arm lifting, sprocket wheel 8 reduces twining amounts, and workplatform be because deadweight and load weight will fall, and sprocket wheel 11 increases twining amounts, the sprocket wheel equal diameter, and the twining amount of increase and decrease is equal, and assurance workplatform and ground-surface angle remain unchanged.When folding arm fell, sprocket wheel 8 increased twining amount, and workplatform will be because deadweight and load weight will be lifted under the chain pulling, and sprocket wheel 11 reduces twining amount, and sprocket wheel equal diameter, the twining amount of increase and decrease equate, guarantee that workplatform and ground-surface angle remain unchanged.
The utility model is owing to introduced the oil cylinder balance, solve the common mechanical balanced system and can not be applied to problem with the aerial platform of telescopic arm structure, owing to adopt sprocket wheel, chain structure, folding arm change angle scope can reach 0-180 °, be convenient to the structural arrangement of aerial platform more, have simple in structure, adaptable characteristics.
