Description

A Double String Insulator Insulation Puller

technical field

The utility model relates to a double-string insulator insulation tractor used for live adjustment of a 66 kV transmission line or live replacement of a complete set of fittings for the head of an insulator and a power failure elastic wire.

Background technique

Electricity is an important basic industry for the development of the national economy and society. With the development of the economy and society, the national economy and people's lives are increasingly dependent on power supply, and the requirements for power supply reliability are getting higher and higher. Power failures caused by accidents Economic losses are also growing. Electric power safety is related to the overall economic situation and people's lives. Any accident may bring irreparable losses to the society, especially the large-scale power outage accident of the power grid, which will cause immeasurable harm and impact on the society. As the social responsibility of the electric power sector, it is to make every effort to maintain the stability of the power grid, ensure social stability, and put the safe operation of the power grid in the first place. However, accidents, dangers, including the impact of force majeure are unpredictable, so there is still a crisis of large-scale power outages in the power grid.

In the work of adjusting the speed of the traditional transmission line and replacing the complete set of fittings on the insulating head, because there is no reasonable method and tool designed, it can only be operated by power failure. The above-mentioned harm caused by power failure to life and economy requires the power department to replace the fittings. During the process, do live work well, and live work is very unsafe for construction personnel.

Utility model content

The technical problem to be solved by the utility model is to provide a targeted double-string insulator insulator puller, which effectively solves the problems of transforming power failure operation to live operation, effectively avoiding induction electric injury and facilitating special pole and tower operations.

The utility model is achieved in this way. It is a double-string insulator insulating tractor. The tractor includes a pull plate, a connecting piece and two hanging plates connected to the connecting piece. The connecting piece is an upper and lower equilateral triangle connecting plate through three The bolts at two corners are connected as shafts to form a structure with a gap in the middle, one end of the pull plate is movably connected to a shaft on the connector, and the two hanging plates are respectively movably connected to the other two shafts on the connector.

Further, the pull plate adopts a high-strength insulating pull plate as the main traction and installation rod. The pull plate has a horizontal structure, one end is a wire end, and the other end is a tower head end. The wire end is reliably connected to the connector. The head end is reliably connected with a high-strength insulated traction rope.

Further, the hanging board is a back hanging board needle structure.

Further, the top of the back of the back hanging board needle structure is 180 degrees, and the inner groove space formed is the same as the space between the upper and lower equilateral triangles. The height of the inner groove at the top of the back is 25mm, and the height of the outer groove is 65mm.

Compared with the prior art, the utility model has the beneficial effects that:

The utility model can change the work of power failure into live operation, improve the power supply and reliability; protect the staff from the damage of induction electricity to the greatest extent, and improve safety; the power failure operation prevents the staff from climbing out to install, and reduces the physical strength of the staff Power consumption; power outage operation saves working time and improves the completion rate of work; the work of special type pole tower and seriously inclined elastic line is more convenient to operate.

Description of drawings

Fig. 1 is a schematic diagram of the equipment structure provided by the embodiment of the present invention.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, a double-string insulator insulation puller, the puller includes a pull plate 1, a connecting piece 2 and two hanging plates 3 connected to the connecting piece 2, the connecting piece 2 is an upper and lower equilateral triangle connecting plate 7 The bolt 8 at three corners is used as a shaft connection to form a structure with a middle gap, and the direction and angle can be adjusted at will. One end of the pull plate 1 is movably connected to a shaft on the connector 2, and the two hanging plates 3 are respectively connected to the The other two shafts on the connector are articulated.

The pull plate 1 uses a high-strength insulating pull plate (3 tons) as the main traction and installation rod. The pull plate 1 has a horizontal structure, one end is the wire end 5, and the other end is the tower head end 4. The wire end 5 is reliably connected to the connector , the tower head end 4 is reliably connected with the high-strength insulating traction rope through the installation hole 6 thereon.

Hanging plate 3 is a needle structure of the back hanging plate. The back hanging plate is designed to be split according to the traditional equipment. On the triangular connector of the line fittings.

The top of the head of the back hanging board needle structure is 180 degrees, and the space formed is the same height as the space between the inner groove 9 and the upper and lower regular triangles, so as to reduce the component force acting on the triangular plate. The height of the inner groove 9 on the top of the head is 25mm, and the outer groove 10, that is, the height of the top of the head is 65mm.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model.
