The tool is simple in structure, and is convenient to operate; and the casing (or CT) can be prevented from being collided in a hoisting process, the operating time is shortened, and the quantity of operating personnel is reduced, and the working efficiency is increased.

Description

Sleeve pipe lifting special tool

Technical field

The utility model relates to a kind of electric system sleeve pipe lifting special tool, belongs to the crane hanger technical field.

Background technology

The voltage transformer of electric system is installed and when safeguarding, runs into the dismounting problem of transformer bushing through regular meeting, and the dismounting of general sleeve pipe is to accomplish through the cooperation of hanging device.Winch in the upright state process by the horizontal positioned state in Oil-impregnated Paper Condenser Bushing in History; The voltage equalizing ball that is positioned at sleeve bottom is stressed very big, normally slings in order to prevent voltage equalizing ball damage and control sleeve pipe, needs with hawser around voltage equalizing ball top; The artificial application of force breaks away from the bottom of the packing chest case voltage equalizing ball; Because the artificial application of force is difficult to tacit agreement with cooperating of the crane application of force, also there is identical problem in voltage equalizing ball owing to unbalance stress and impaired phenomenon happens occasionally when making the sleeve pipe lifting in the hoisting process of CT; Above-mentioned in addition hanging method also exists production time length, needs defectives such as operating personal quantity is many.

The utility model content

The purpose of the utility model is the drawback to prior art, provide a kind of simple in structure, easy to operate, can effectively avoid the sleeve pipe lifting special tool that parts damage phenomenon takes place in the Casing elevator process of assembling.

The said problem of the utility model realizes with following technical proposals:

A kind of sleeve pipe lifting special tool, it comprises coaster and adapter plate, and said coaster and sleeve bottom are equipped, and said adapter plate is installed in the sleeve pipe top, and the sleeve pipe lifting rope is connected with the casing flange suspension ring after passing adapter plate.

Above-mentioned sleeve pipe lifting special tool; Said coaster is made up of sleeve pipe registration mast, bracing frame and two rubber and plastic wheels; Said sleeve pipe registration mast one end is fixed on the bracing frame, in the copper conductor tube of other end threading afterbody, and stay bearing plate that support frame as described above comprises rectangular configuration and the rubber and plastic wheel mount pad that is fixed on below the stay bearing plate; On stay bearing plate, be provided with buffering rubber, said rubber and plastic wheel is fixed on the rubber and plastic wheel mount pad through axle pin.

Above-mentioned sleeve pipe lifting special tool, said adapter plate is the diamond plate structure, heart position is provided with the assembly opening that matees with the sleeve pipe top therein, and the hole for hoist that supplies lifting rope to pass is set respectively in its both sides.

The utility model defines lifting rope puts on casing flange suspension ring upper pulling force in the lifting process direction through the hole for hoist on the adapter plate; Rolling through coaster rubber and plastic wheel cooperates sleeve pipe by the space spinning movement of horizontal positioned state to setting; On the stay bearing plate of coaster, be provided with buffering rubber, and the sleeve pipe registration mast is inserted in the copper conductor tube of sleeve pipe afterbody; Above measure fully guaranteed sleeve pipe in hoisting process stressed steadily, strange phenomena such as do not collide with makes sleeve pipe (or CT) safety in place.The utility model is simple in structure, and is easy to operate, can not only guarantee the steady lifting of sleeve pipe (or CT), and shorten production time, reduced operating personal quantity (only needing two people can accomplish the sleeve pipe lifting), improved work efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is pulley structure figure;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the adapter plate constructional drawing;

The utility model working state schematic representation when Fig. 4 is the sleeve pipe lifting;

Fig. 5 is that sleeve pipe is in and rotates certain working state schematic representation of the utility model in a flash;

Fig. 6 is sleeve pipe the utility model working state schematic representation when being in the erection position.

Each label is among the figure: 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, during constituting, the utility model comprises coaster 1 and adapter plate 2, and said coaster 1 is equipped with sleeve pipe 3 bottoms, and said adapter plate 2 is installed in sleeve pipe 3 tops, and sleeve pipe lifting rope 4 passes adapter plate 2 backs and is connected with casing flange suspension ring 3-1.

Referring to Fig. 1, Fig. 2; Coaster 1 during the utility model constitutes is made up of sleeve pipe registration mast 1-1, bracing frame and two rubber and plastic wheel 1-3; Said sleeve pipe registration mast 1-1 one end is fixed on the bracing frame, in the copper conductor tube of other end threading afterbody, and stay bearing plate 1-2 that support frame as described above comprises rectangular configuration and the rubber and plastic wheel mount pad 1-4 that is fixed on below the stay bearing plate 1-2; On stay bearing plate 1-2, be provided with buffering rubber 1-5, said rubber and plastic wheel 1-3 is fixed on the rubber and plastic wheel mount pad 1-4 through axle pin.

Referring to Fig. 3, the adapter plate 2 during the utility model constitutes is the diamond plate structure, and heart position is provided with the assembly opening 2-1 that matees with the sleeve pipe top therein, and the hole for hoist 2-2 that supplies lifting rope 4 to pass is set respectively in its both sides.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6; And combine specific embodiment that the working process and the principle of work of the utility model are described: before sleeve pipe 3 liftings; Adapter plate 2 is installed on the junction block at sleeve pipe top through the assembly opening 2-1 and the assembly set that is threaded, and the hole for hoist 2-2 that lifting rope 4 passes the adapter plate two ends is connected with casing flange suspension ring 3-1.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 are formed, 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 the coaster 1, and coaster 1 smooth rotation prevents sleeve pipe 3 stressed sudden changes; Hole for hoist 2-2 on the adapter plate defines lifting rope 4 puts on casing flange hoisting ring 3-1 upper pulling force in the lifting process direction; The buffering rubber 1-5 that on the stay bearing plate of coaster, is provided with has alleviated the impact that hoisting process middle sleeve afterbody voltage equalizing ball receives.Above measure fully guaranteed sleeve pipe 3 in hoisting process stressed steadily, strange phenomena such as do not collide with makes sleeve pipe (being equally applicable to CT) safety in place.Realized that sleeve pipe 3 steadily slings.
