Abstract
The utility model discloses a special hoisting tool for transformer sleeves, which is in the structure of a grate barrel. A circular steel tray is used as a base and welded with a perpendicular steel vertical post connected with the outer edge of the circular steel tray, two circular steel strip hoops are welded on the perpendicular steel vertical post, and small guide holes are arranged on the outsides of the two circular steel strip hoops. Lugs with holes are arranged on two outer sides of the perpendicular steel vertical post, a central hole is arranged at the center of the steel tray, and three fixed holes in equilateral triangle arrangement at the same interval are arranged on the periphery of the central hole utilized as the center. The special hoisting tool for the transformer sleeves is capable of hoisting high-voltage sleeves of 750kV transformers quickly and effectively and simultaneously effectively eliminating safety risks during hoisting of the high-voltage sleeves of the 750kV transformers.
Description
Technical field
The utility model belongs to power engineering and special tool for examination and repair, relates in particular to a kind of special tool of transformer bushing lifting.
Background technology
At present, known 750kV transformer high-voltage sleeve pipe is the porcelain sleeve pipe, and deadweight and volume are bigger, and lifting is difficulty very, causes easily and damages sleeve pipe in the hoisting process.In hoisting process in the past, note thing such as soft cardboard or cotton on nylon sling and the contacted position of sleeve pipe porcelain spare pad, in case porcelain spare is damaged in the stressed back of nylon sling.
The utility model content
The utility model is in order to overcome the deficiency of existing lifting device in 750kV transformer high-voltage sleeve pipe installation process, and the utility model provides a kind of safe and simple, easy-to-use lifting device.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of special tool of transformer bushing lifting; It is characterized in that: this special tool profile is the fence barrel-like structure; Be to be support with a steel plate disk; Be welded with the vertical steel plate column that is connected with steel plate disk outward flange, on vertical steel plate column, be welded with two ring shape steel plate straps, and be provided with little pilot hole in the ring shape steel plate strap outside; Be welded with hanger with holes in vertical steel plate column two outsides, be provided with a circular centre hole and be that central peripheral is provided with the special tools that three little fixed orifices that three equidistance are the equilateral triangle layout are formed the transformer bushing lifting with the centre hole in the steel plate disc centre.
The beneficial effect of the utility model: the special tool of a kind of transformer bushing lifting that the utility model provides; The special tool of this transformer bushing lifting can not only lift 750kV transformer high-voltage sleeve pipe fast and effectively, and can stop the security risk of 750kV transformer high-voltage sleeve pipe in hoisting process effectively.And after using the special tool of transformer bushing lifting, the prolongation of hanger can effectively make the stressed back of nylon sling not come in contact in sleeve pipe porcelain spare part, can fundamentally stop because of lifting sleeve pipe to be caused damage.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Fig. 1 is the special tool master TV structure scheme drawing of transformer bushing lifting;
Fig. 2 is the left TV structure scheme drawing of Fig. 1;
Fig. 3 is the plan structure scheme drawing.
The specific embodiment
Shown in accompanying drawing 1-3; The special tool of a kind of transformer bushing lifting of the utility model; This special tool profile is the fence barrel-like structure, is to be support with a steel plate disk 1, is welded with the vertical steel plate column 2 that is connected with steel plate disk 1 outward flange; On vertical steel plate column 2, be welded with two ring shape steel plate straps 3, and be provided with little pilot hole 7 in ring shape steel plate strap 3 outsides; Be welded with hanger 6 with holes in vertical 2 liang of outsides of steel plate column, be provided with a circular centre hole 4 at steel plate disk 1 center and be that central peripheral is provided with three little fixed orifices 5 that three equidistance are the equilateral triangle layout and forms the special tools that transformer bushing lift with centre hole 4.
At the 750kV casing flange the special-purpose suspension ring of effective 2 20T of lifting cover are installed; The sleeve pipe tip position adopts the special tool of transformer bushing lifting; The sleeve pipe top metal is partly covered in its inside, and the special tool both sides of transformer bushing lifting install pilot hole additional, and lifting rope is passed in pilot hole; Guarantee that sleeve pipe is in vertical position in hoisting process, can prevent that transformer bushing from toppling simultaneously effectively to cause the device damage accident in the emepalcement casing process.
