Description

Monolithic Insulator Fixtures

technical field

The utility model relates to a monolithic insulator fixing device.

Background technique

Glass insulators are widely used in power transmission lines, and one of the characteristics of glass insulators is zero value self-explosion. Therefore, an important task in line operation and maintenance is to replace self-explosive insulators. In this process, it is necessary to fix and lift single-piece insulators. The traditional method of fixing single-piece insulators is to bind and fix them with ropes, which have certain technical requirements for binding. When the ropes are thick, the binding is difficult, and it is not easy to bind firmly. During the lifting process, the insulator may contact the tower body, and there is a certain height Hazard of falling objects.

Contents of the invention

The purpose of the utility model is to provide a monolithic insulator fixing device, which is used to solve the problem of replacing the glass insulator after self-explosion, simplify the operation procedures, and avoid damage and safety accidents caused by the falling of the glass insulator.

Technical solutions:

The monolithic insulator fixing device includes a card body 2 and a handle frame 5, and the card body 2 and the handle frame 5 are bent and fixed together with steel bars, wherein the circular socket 4 in the card body 2 is connected to the card slot 3 become a chamber; the handle frame 5 is made into a slingshot frame shape, and a shaft 1 is fixed as a handle at the inner sides of the two pole tops constituting the frame body.

Suit handle cover 6 on the shaft, the two are connected in a rotational manner. The card body 2 is bent into a U-shaped cavity by a steel bar as the card slot 3; a circular socket 4 is made at the inner end of the U-shaped cavity as the socket entrance of the spherical head of the glass insulator. The whole card body 2 is made into an arc shape, which is convenient for the insulator entering the card slot to slide to the end smoothly, and when holding the handle, it is not easy to return to the circular socket.

According to the above method, a single-piece insulator fixing device is made. The circular sleeve and the slot are made according to the shape and size of the spherical head of the insulator, and the openings of the two parts are different in size and shape. The shaped socket enters the combination cavity, and then slides into the card slot to fix the spherical head of the insulator. The upper end is equipped with a rotating handle for lifting, which is convenient for operation and effectively solves the problem of fixing the single-piece insulator.

The monolithic insulator fixing device made in the above way can conveniently insert the glass insulator into the slot. During use, the handle frame is at the highest position and the lower end of the slot is at the lowest position, so the glass insulator will not slip off. The pull rope used in the work is tied to the handle cover and hoisted to the tower of the power transmission line. The operator can easily remove the insulator for replacement without the trouble of untying the rope.

Description of drawings

Fig. 1 is a structural schematic diagram of a monolithic insulator fixing device.

Fig. 2 is a side view of the monolithic insulator fixing device.

Detailed ways

The technical solution will be further described below in conjunction with the accompanying drawings as an embodiment.

Referring to Fig. 1, the monolithic insulator fixing device of this example is made by bending 6mm steel bars; the handle frame 5 is made of two frame rods bent into an angular shape at the inner end, and a transverse rectangular shape at the outer end, that is, it is composed of an angular shape and a rectangular shape. To form a frame body, press the openings of the two frame rods that constitute the frame body into a flat body, open a hole on the side, install a shaft 1, and fix it with a nut 7, put a handle cover 6 on the shaft 1, and form a shape with the shaft. Turn to connect.

Make card body 2 with the steel bar of same specification again, adopt a steel bar to bend out circular socket 4 and draw-in groove 3, the two are connected into a chamber; Determined, the lateral dimension of the clamping groove 3 must be smaller than the diameter of the spherical head of the lower glass insulator, so that the glass insulator can be stuck in the groove without falling, and slide in the groove easily. The outer end of the slot 3 is made into an arc shape, so that the insulator inserted therein can slide without being scratched.

The handle frame 5 and the card body 2 completed in the above manner are welded together to form a monolithic insulator fixing device.

In actual production, according to the length of the designed single-piece insulator fixing device, calculate the size of the overall required steel bar, cut it, bend and press it, and press the joint of the handle frame 5 and the card body 2 to form a joint made of two steel bars. The shin, and then a little welding treatment and polishing.

Referring to Figure 2, the monolithic insulator fixing device completed in the above way also needs to bend the front of the card body upwards into an arc, so as to benefit the glass insulator inserted in the card slot during sliding to the end. In the initial stage, there is a slow slope instead of rushing directly to the bottom of the card slot to avoid impact, and when the handle frame is lifted, slide to the end of the card slot. Finally, tie it to the sling and lift it to the tower of the line to replace the broken glass insulator.

In the operation of replacing a single-piece insulator, the trouble of directly tying the shank of the insulator with a rope is eliminated, and the trouble of understanding the knot is saved when hoisting it to the line, and the problem of the insulator slipping due to a miss is avoided. It has achieved the effect of saving time and improving work efficiency.
