In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of wind-powered electricity generation unit maintenance hanging device comprises frame 1, jaw system, elevator system, tackling system, hydraulic efficiency pressure system 3 and control system 2, and hydraulic efficiency pressure system 3 provides power through control system 2 pairs of jaw systems, elevator system and tackling systems;
Be equipped with above the frame 1 and promote, be fixed with assembly pulley 15 above the A of blower fan cabin with hoisting system 4, promote with hoisting system 4 through promote with steel rope 5 and assembly pulley 15 be linked together the composition elevator system;
Hold-down arm 12 is hinged with revolution support 6 through second pin 8 in the tackling system; Revolution is supported 6 and is assemblied in above the frame 1; Support cylinder 10 lower ends are hinged with revolution support 6 through first pin 7, and the upper end is hinged with hold-down arm 12 through the 4th pin 13;
Lifting is assembled together through support 19 and arm 23 with hoisting system 17, and suspension hook 25 is formed lifting assembly with steel rope 24 and lifting with hoisting system 17 through lifting;
Described hold-down arm 12, support cylinder 10, arm 23, lifting oil cylinder 11 and lifting assembled are formed tackling system together.
Described hydraulic efficiency pressure system 3 is assemblied in above the frame 1 with control system 2.
Advantage of the present invention is in light weight, convenient transport; Need not assembled on site, simple operation; The operation and maintenance cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
With reference to accompanying drawing, a kind of wind-powered electricity generation unit maintenance hanging device comprises frame 1, jaw system, elevator system, tackling system, hydraulic efficiency pressure system 3 and control system 2, and hydraulic efficiency pressure system 3 provides power through control system 2 pairs of jaw systems, elevator system and tackling systems;
Be equipped with above the frame 1 and promote with hoisting system 4; Be fixed with assembly pulley 15 above the A of blower fan cabin; Promote with hoisting system 4 through promote with steel rope 5 and assembly pulley 15 be linked together the composition elevator system, provide power that whole lifting appliance is risen to the lifting operation height from ground through hydraulic efficiency pressure system 3 and control system 2;
Jaw system is held with a firm grip after the tower tube C; The tackling system of starting outfit; Hold-down arm 12 supports 6 hingedly in the tackling system through second pin 8 and revolution, and revolution is supported 6 and is assemblied in above the frame 1, and support cylinder 10 lower ends are supported 6 hinged through first pin 7 and revolution; The upper end is hinged through the 4th pin 13 and hold-down arm 12, and the power that provides through hydraulic efficiency pressure system 3 and control system 2 is to realize the pitching action of hold-down arm 12 and to provide support power;
Described hydraulic efficiency pressure system 3 is assemblied in above the frame 1 with control system 2.
Principle of work of the present invention is:
A kind of wind-powered electricity generation unit maintenance hanging device comprises frame 1, jaw system, elevator system, tackling system, hydraulic efficiency pressure system 3 and control system 2, and elevator system will be keeped in repair hanging device and risen to liftoff about 80 meters high-altitude; The startup jaw system will keep in repair hanging device and be fixed on above the blower fan tower barrel C, start tackling system subsequently and carry out wind-powered electricity generation maintenance lifting operation, can the electrical generator among the A of cabin, gearbox B etc. be winched to ground; Or ground installation hung in assigned address in the cabin; After lifting operation was accomplished, jaw system unclamped, and elevator system starts; To keep in repair hanging device and put to ground handling trolley, just realize that the maintenance lifting of a wind-powered electricity generation unit is done.
Hydraulic efficiency pressure system 3 at first provides power that whole lifting appliance is risen to the lifting operation height from ground to tackling system with control system 2 in the work; To top jaw components 26 and bottom jaw components 28 power is provided subsequently, jaw components tightens up the blower fan tower barrel C that holds, and provides support with this; Provide power to realize the pitching action of hold-down arm 12 and to provide support power to support cylinder 10 again; Provide power to realize to lifting oil cylinder 11 subsequently and the lifting bearing force is provided the pitching operation of arm 23; Provide power with the lifting operation of realization to Awaiting Parts in the wind-powered electricity generation set engine room to tackling system at last, or terrestrial components is lifted in the cabin, according to the control system requirement, the sequential analysis of each several part hydraulic unit is also kept packing state in the entire work process.
