Abstract
The invention relates to a special tool for lifting a bushing, which is used for realizing stable lifting of a transformer bushing or a CT (Current Transformer). The special tool comprises a tackle and a fixed plate, wherein the tackle is assembled at the bottom part of the bushing; the fixed plate is arranged at the top part of the bushing; and a lifting rope of the bushing penetrates through the fixed plate and then is connected with a flange lifting ring of the bushing. The special tool has the advantages that the structure is simple, the operation is convenient, not only can the bushing or CT be prevented from being collided and impacted in the lifting process, but also the operation time is shortened, the number of operators is reduced, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of electric system sleeve pipe tool special for hoisting, belong to lifting technique field.
Background technology
When the voltage transformer of electric system is installed and safeguards, often can run into the dismounting problem of transformer bushing, the dismounting of general sleeve pipe is that the cooperation by hanging device completes.In Oil-impregnated Paper Condenser Bushing in History, by horizontal positioned state, rise and winch in upright state process, the voltage equalizing ball that is positioned at sleeve bottom is stressed very large, in order to prevent voltage equalizing ball damage and to control sleeve pipe and normally sling, need to be with hawser around voltage equalizing ball top, at the bottom of the artificial application of force makes voltage equalizing ball depart from packaging box, because the artificial application of force is difficult to tacit agreement with coordinating of the crane application of force, while making sleeve hoisting, due to unbalance stress, impaired phenomenon happens occasionally voltage equalizing ball, also has identical problem in the hoisting process of CT; Above-mentioned hanging method also exists production time length, needs the defects such as operating personal quantity is many in addition.
Summary of the invention
The object of the invention is to the drawback for prior art, a kind of simple in structure, easy to operate, the sleeve pipe tool special for hoisting that can effectively avoid the damage of parts in Casing elevator process of assembling phenomenon to occur is provided.
Problem of the present invention realizes with following technical proposals:
A tool special for hoisting, it comprises coaster and adapter plate, and described coaster and sleeve bottom are equipped, and described adapter plate is arranged on sleeve pipe top, and sleeve pipe lifting rope is connected with casing flange suspension ring through after adapter plate.
Above-mentioned sleeve pipe tool special for hoisting, described coaster is comprised of sleeve pipe registration mast, bracing frame and two rubber and plastic wheels, described sleeve pipe registration mast one end is fixed on bracing frame, in the copper conductor tube of other end threading afterbody, support frame as described above comprises the stay bearing plate of rectangular configuration and is fixed on the rubber and plastic wheel mount pad below stay bearing plate, on stay bearing plate, be provided with buffering rubber, described rubber and plastic wheel is fixed on rubber and plastic wheel mount pad by axle pin.
Above-mentioned sleeve pipe tool special for hoisting, described adapter plate is diamond plate structure, heart position is provided with the assembly opening mating with sleeve pipe top therein, and the hole for hoist passing for lifting rope is set respectively in its both sides.
The present invention defines lifting rope by the hole for hoist on adapter plate and in lifting process, puts on the direction of casing flange suspension ring upper pulling force; The rolling of taking turns by coaster rubber and plastic coordinates sleeve pipe to be moved by horizontal positioned state to the Space Rotating of erectting; On the stay bearing plate of coaster, be provided with buffering rubber, and sleeve pipe registration mast inserted in the copper conductor tube of sleeve pipe afterbody; Above measure fully guaranteed sleeve pipe in hoisting process stressed steadily, the strange phenomena such as do not collide with, makes sleeve pipe (or CT) safety in place.The present invention is simple in structure, easy to operate, can not only guarantee the steady lifting of sleeve pipe (or CT), and shorten production time, has reduced operating personal quantity (only needing two people can complete sleeve pipe lifting), has improved work efficiency.

In figure, each label is: 1, coaster, 1-1, sleeve pipe registration mast, 1-2, stay bearing plate, 1-3, rubber and plastic wheel, 1-4, rubber and plastic wheel mount pad, 1-5, buffering rubber, 2, adapter plate, 2-1, assembly opening, 2-2, hole for hoist, 3, sleeve pipe, 3-1, casing flange suspension ring, 4, lifting rope.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the present invention's formation comprises coaster 1 and adapter plate 2, and described coaster 1 is equipped with sleeve pipe 3 bottoms, and described adapter plate 2 is arranged on sleeve pipe 3 tops, and sleeve pipe lifting rope 4 is connected with casing flange suspension ring 3-1 through adapter plate 2 is rear.
Referring to Fig. 1, Fig. 2, coaster 1 during the present invention forms is comprised of sleeve pipe registration mast 1-1, bracing frame and two rubber and plastic wheel 1-3, described sleeve pipe registration mast 1-1 one end is fixed on bracing frame, in the copper conductor tube of other end threading afterbody, support frame as described above comprises the stay bearing plate 1-2 of rectangular configuration and is fixed on the rubber and plastic wheel mount pad 1-4 below stay bearing plate 1-2, on stay bearing plate 1-2, be provided with buffering rubber 1-5, described rubber and plastic wheel 1-3 is fixed on rubber and plastic wheel mount pad 1-4 by axle pin.
Referring to Fig. 3, the adapter plate 2 during the present invention forms is diamond plate structure, and heart position is provided with the assembly opening 2-1 mating with sleeve pipe top therein, and the hole for hoist 2-2 passing for lifting rope 4 is set respectively in its both sides.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, and working process of the present invention and principle of work are described in conjunction with specific embodiments: before sleeve pipe 3 liftings, adapter plate 2 is installed on the junction block at sleeve pipe top by assembly opening 2-1 and the assembly set that is threaded, and lifting rope 4 is connected with casing flange suspension ring 3-1 through the hole for hoist 2-2 at adapter plate two ends.Afterbody at sleeve pipe 3 is installed coaster 1, and coaster is by a length 20cm, and the sleeve pipe registration mast 1-1 of the metal tube material of diameter 3 inch and two rubber and plastic wheels form, and sleeve pipe registration mast 1-1 are inserted in the copper conductor tube of sleeve pipe afterbody.During lifting, the part weight of sleeve pipe 3 is pressed on coaster 1, and coaster 1 smooth rotation prevents the stressed sudden change of sleeve pipe 3; Hole for hoist 2-2 on adapter plate defines the direction that lifting rope 4 puts on casing flange hoisting ring 3-1 upper pulling force in lifting process; The buffering rubber 1-5 arranging on the stay bearing plate of coaster, has alleviated the impact that hoisting process middle sleeve afterbody voltage equalizing ball is subject to.Above measure fully guaranteed sleeve pipe 3 in hoisting process stressed steadily, the strange phenomena such as do not collide with, makes sleeve pipe (being equally applicable to CT) safety in place.Having realized sleeve pipe 3 steadily slings.
