Folding arm configuration floor space is small, and crane capacity is strong.In order to increase height, which is provided with a section and stretches
Contracting arm, meanwhile, the present invention folds arm front end and is provided with fork configuration arm, and for straight-arm, operating radius accordingly reduces, but
Crane capacity increases, while the equipment that lifted by crane can be placed on inside forks arm, reduces boundary of works area, therefore the invention is selected
With folding arm（Increase Telescopic）+ fork-shaped arm configuration.
During actual fabrication, rectangular section can use by folding arm, and manufacturing process is simple, with preferable bending resistance and antitorque
Rigidity, the arm support development for being suitable for the present invention, telescopic arm can be used by the Bi -- directional Compression -- Flexure elliptical section component based on curved, upper curved
Plate is orthodrome trough plate, and lower bent plate is oval trough plate, and is shunk from bottom to top, its is Weight-optimised, and torsional property is notable,
With intrinsic unique stability and distortion resistance, the technology of ellipse lifting represents highest level, adds due to being not required to use
Muscle, thus varying less per joint arm section, are conducive to mitigate the weight of lifting horn, improve the crane capacity of lifting machine.
Lifting uses " Z " font hydraulic pressure or the folding structure of electric up-down.This most significant advantage of structure is to take
Space is small, large carrying capacity.The support system of " Z " font lifting can be horizontally fixed in the upper plane on chassis.Lifting rises
One opening of crane system Front-end Design and the ring frame that can be closed, ring frame inner wall can be with lining batten or rubber pad.Annular
Frame and the fixed design of tackling system front end are protected all the time into rotatable structure, guarantee ring frame in each angle of lifting movement
Horizontal level is held, ring frame periphery is arranged as required to appropriate number of suspension hook, to be used when facilitating dismounting or installation equipment.Example
Such as：When dismounting PT/CT, which can be fixed on to the outside of insulator, the batten or rubber pad of ring frame inner wall lining
It can ensure that insulator can effectively avoid the collision with metal ring frame in operation process, by adjusting the length of lifting rope, the ring
Shape frame can also play the role of preventing device inclined from overturning.
Steel wire rope zipper structure is set inside tackling system front end, and lever arm is internally provided with oil cylinder, can be moved by oil cylinder
Make to drive zipper structure, carry out fine setting up and down.Tackling system front end is equipped with hood type hanging ring, and hood type hanging ring not only rises during lifting
To fixation（Do not clamp）Effect（Pass through both sides hand actuable clamping device）, may also function as suspension hook effect；Hood type hanging ring lower end connects
There is circular sliding slot, the effect of circular sliding slot is can be easily installed with rotating weight.During lifting, hood type hanging ring and circular sliding slot position
In power equipment center of gravity with upper bit, the stability during lifting ensure that.
In practical applications, the bottom of mobile foundation sets roller, and roller can be rolled by electric drive or manual actuation
Wheel includes the universal wheel for being arranged on mobile foundation front end and the driven wheel for being arranged on mobile foundation rear end, and brake is set on driven wheel
Device, can be realized using rubber brake block.
Manufacture and put into practice using display through applying unit, the planned cost of apparatus of the present invention every is 30,000 yuan, and total cost is
150000 yuan.The present invention has carried out preliminary experiment, functional, can lift by crane the weight within 200 kilograms.Lifting altitude is 3 meters,
Radius of turn is 1.2 meters, i.e., weight can be seated to the optional position in radius by the rotation for having crossbeam by top, can
Meet most of substation's interior constructions, can be promoted in the whole nation, very big economic benefit will be produced after coming into operation, because
This with good economic efficiency and social benefit.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common
Other modifications or equivalent substitution that technical staff makes technical scheme, without departing from technical solution of the present invention
Spirit and scope, should all cover among scope of the presently claimed invention.
