Abstract
The utility model discloses a lifting tool special for a tension-proof insulator hollow connection board. The lateral face of the lifting tool is 'U'-shaped, and a lifting hole is arranged on the upper portion of the lateral face. The front faces on two sides of the 'U' shape are symmetrical in shape, an isosceles triangle body is arranged on the upper portion, a rectangle body is arranged on the lower portion, a lifting hole is arranged at the middle upper position of the isosceles triangle body, and the two sides of the 'U' shape are fixedly connected through at least two bolts on the rectangle body. A gap is retained between the two sides of the 'U' shape through nuts to form a 'U'-shaped bottom. When the tension-proof insulator hollow connection board is replaced, the lifting tool is used for lifting. Compared with the prior iron wire fixation, the lifting tool effectively reduces hollow connection board fixing time and improves safety factor of the workers.
Description
Technical field
The utility model relates to a kind of strain insulator hollow connecting plate special hanger.
Background technology
Sometimes need change strain insulator hollow connecting plate during the 220kV power transmission lines overhauling; When originally changing; Need to adopt 15 tons of lifting ring, be fixed in the middle of the strain insulator hollow connecting plate with iron wire, operating process is trouble; (center of gravity) position is difficult in the middle of the strain insulator hollow connecting plate grasps, and coefficient of safety is low.
The utility model content
The technical problem that the utility model will solve provides a kind of strain insulator hollow connecting plate special hanger, and it has characteristics such as simple in structure, easy to use, safe.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: its side is " U " shape, is provided with lifting hole(eyelet) or suspension hook at an upper portion thereof.
The utility model further improves and is: the front shape of " U " shape both sides is symmetrical; The top is the isoceles triangle body; The below is a rectangular body, is provided with lifting eye in the position, middle and upper part of isoceles triangle body, on rectangular body, is fixedly connected through the both sides of two bolts with " U " shape at least; And make through locknut between the both sides of " U " shape and leave the gap, form " U " shape bottom.
Adopt the beneficial effect that technique scheme produced to be: this suspender is made according to the shape and the design feature of strain insulator hollow connecting plate; The suspender top is the isoceles triangle body, is provided with lifting eye in the position, middle and upper part of isoceles triangle body, and such body can alleviate the weight of suspender; And lifting eye is positioned on the balance point of suspender; Suspender does not produce inclination during lifting, and the iron wire immobile phase ratio with has before reduced the set time; Reduce staff's labour intensity, increased coefficient of safety.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of the utility model;
Fig. 3 is that the utility model uses sketch map.
In the accompanying drawings: 1, isoceles triangle body; 2, rectangular body; 3, lifting eye; 4, bolt; 5, strain insulator hollow connecting plate.
Embodiment
Embodiment by shown in Fig. 1-3 can know that its side is " U " shape, is provided with lifting hole(eyelet) or suspension hook at an upper portion thereof; The front shape of " U " shape both sides is symmetrical; The top is an isoceles triangle body 1, and the below is a rectangular body 2, and the hollow part length of its length and strain insulator hollow connecting plate is suitable; Position, middle and upper part at isoceles triangle body 1 is provided with lifting eye 3; On rectangular body 2 at least through two bolts 4 will " U " shape the both sides fixed connection, these two bolts are arranged on the two ends of rectangular body 2, and make through locknut between the both sides of " U " shape and leave the gap; The width of its gap width and strain insulator hollow connecting plate is suitable, forms " U " shape bottom.
Method for using:
The hollow part of strain insulator hollow connecting plate is inserted in this suspender " U " shape groove; Can accomplish lifting operation through the lifting eye lifting; Iron wire immobile phase ratio with has before reduced the fixedly strain insulator hollow connecting plate time, has increased staff's coefficient of safety.
Claims (2)
1. strain insulator hollow connecting plate special hanger is characterized in that: its side is " U " shape, is provided with lifting hole(eyelet) or suspension hook at an upper portion thereof.
2. a kind of strain insulator hollow connecting plate special hanger according to claim 1; The front shape that it is characterized in that said " U " shape both sides is symmetrical; The top is isoceles triangle body (1); The below is rectangular body (2), is provided with lifting eye (3) in the position, middle and upper part of said isoceles triangle body (1), on said rectangular body (2), is fixedly connected through the both sides of two bolts (4) with " U " shape at least; And make through locknut between the both sides of " U " shape and leave the gap, form " U " shape bottom.
