It can save a lot of expenses spent on safety production prevention work, and greatly reduce safety hazards in work.

Description

Safety Belt Suspension Device for Transformer Maintenance

technical field

The utility model belongs to the technical field of electric system safety protection devices, in particular to a safety belt suspension device for transformer maintenance.

Background technique

In the power system, the topic of "safety" has always been the top priority in the daily work of the front-line workshop. Some of the main transformer inspection rooms are mainly responsible for the inspection and maintenance of transformers above 35kV in the power grid. The height of the 35kV transformer body is about 2.5 meters, and the body height of the 110kV, 220kV, and 500kV transformers is much higher than this height, and maintenance personnel often need to go on board. On the transformer and engaged in maintenance work on its cover. Because working at heights is extremely dangerous, you need to wear a seat belt. However, it is extremely difficult to find a suitable suspension point for the safety belt on the transformer box cover, so improper suspension is likely to cause the following dangers:

1. The maintenance work is usually not carried out at a fixed location, and it is often necessary to walk on the box cover. It is extremely unfavorable to carry out the work if the seat belt is fastened to one point. Repeatedly hanging the seat belt will increase the labor load of the maintenance personnel;

2. The transformer box cover after the accessories are removed usually has no seat belt suspension point, and the seat belt can only be fastened close to the box cover, resulting in the situation of low hanging and high use. Security risks.

3. If you don’t wear a seat belt, it will not only violate the safety operation regulations, but also easily cause the danger of staff falling from high altitude.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a safety belt suspension device for transformer maintenance.

In order to achieve the above purpose, the safety belt suspension device for transformer maintenance provided by the utility model includes one or two vertical rods and steel wire ropes; the vertical rod is made of glass fiber reinforced plastic material, which is composed of a flange, an insulating rod and a rotatable suspension ring. There are multiple screw holes formed on the edge of the flange, and the flange is fixed on the transformer box cover by means of screws passing through the screw holes; the lower end of the insulating rod is fixed in the middle of the flange surface; the rotatable lifting ring is fixed on the upper end of the insulating rod; the two wire ropes The ends are respectively fixed between the upper ends of two vertical poles or the upper end of a vertical pole and the rotatable lifting ring installed on the transformer accessories.

The length of the insulating rod is 1200mm, and the diameter is 55mm.

The flange is a square plate.

The safety belt suspension device for transformer maintenance provided by the utility model has the following beneficial effects:

1. It can reduce the number of seat belt suspensions during work and facilitate mobile work, so it can improve the safety of maintenance work and reduce personal safety hazards.

2. It can avoid the situation that the seat belt is hung low and used high, and abides by the on-site safety operation regulations.

3. It can save a lot of expenses spent on safety production and prevention work, and greatly reduce safety hazards in work.

Fig. 1 is a schematic diagram of the use state of the safety belt suspension device for transformer maintenance provided by the utility model.

Fig. 2 is a schematic diagram of the structure of the pole in the safety belt suspension device for transformer maintenance provided by the utility model.

Fig. 3 is a schematic diagram of the structure of the flange in the pole shown in Fig. 2 .

Detailed ways

The safety belt suspension device for transformer maintenance provided by the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-3, the safety belt suspension device for transformer maintenance provided by the utility model includes one or two vertical poles 1 and steel wire ropes 2; The insulating rod 4 and the rotatable lifting ring 5 are formed, wherein the edge of the flange 3 is formed with a plurality of screw holes 6, and the flange 3 is fixed on the transformer box cover by means of screws passing through the screw holes 6; the lower end of the insulating rod 4 is fixed on the flange. The middle part of the surface of the blue 3; the rotatable lifting ring 5 is fixed on the upper end of the insulating rod 4;

The length of the insulating rod 4 is 1200mm, and the diameter is 55mm.

The flange 3 is a square plate.

Now the method of using the safety belt suspension device for transformer maintenance provided by the utility model is described as follows:

When maintenance personnel need to carry out maintenance work on the transformer box cover, if there is a suspension point on the transformer box cover, only a vertical pole 1 is needed, and a rotatable lifting ring 5 is fixed on the suspension point at the same time, as shown in the figure 1, then connect the wire rope 2 between the upper ends of two vertical poles 1 or the upper end of a vertical pole 1 and the rotatable suspension ring 5 installed at the suspension point, then fasten the buckle on the safety belt to the steel wire rope 2, and then As the work is carried out, the safety belt buckle can move on the wire rope 2 when the maintenance personnel walks, which saves the work of repeatedly fixing the safety belt, and can also prevent the maintenance personnel from hanging the safety belt at a low level and using it at a high level.
