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 outages 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 for the insulating head fixture, because there is no reasonable method and tool designed, it can only be operated with a power outage. The above-mentioned harm caused by a power outage to life and the economy requires the power department to replace the fittings. During the construction process, live work is done 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 crimping tube-type tension clamp insulation tractor, which effectively solves the problem of transforming power failure operation to live operation, effectively avoiding induction electric injury and facilitating special pole and tower operations. question.

The utility model is achieved in this way, a crimping tube type insulating tractor, the tractor includes a pull plate and a head clamp, the pull plate is an insulating pull plate, the insulating pull plate is used as the main traction and installation rod, and the wire The end and the head fixture are connected by bolts. The top of the head fixture faces the direction of the pulling plate, and on the vertical surface with the direction of the pulling plate, there are vertical grooves and flat grooves intersecting to form a cross-shaped groove. The vertical groove is an open structure. , so that it can ride on the vertical U-shaped hanging ring, and the flat groove can hold the flat U-shaped hanging ring after tightening.

In the above technical solution, further, the two ends of the pull plate are the wire end and the tower head end respectively, and the tower head end has installation holes for reliable connection of high-strength insulated traction ropes, through which the tower head end and the head clamp bolts connect.

Further, in the above technical solution, a U-shaped clamp is arranged horizontally on the upper end of the head clamp, and the pull plate is inserted and pushed into the U-shaped clamp and fixed by bolts.

Compared with the prior art, the utility model has the beneficial effects that: the utility model can be used to solve the problem of adjusting the slack of the conductor when the 66 kV line is live, replacing the full set of insulator head fixtures with the 66 kV line Elastic wires, as well as the work of elastic wires when crossing is likely to generate a large induction current and the work of elastic wires with severe downward slope of the 66 kV line terminal tower, can change the work of power failure into live operation, improve power supply and reliability, and maximize Limit the protection of workers from the damage of induction electricity and improve safety; the power failure operation prevents the staff from climbing out to install, reducing the physical exertion of personnel; the power failure operation saves working time and improves the completion rate of work; special type tower and serious The work of the descending elastic wire is more convenient to operate.

Fig. 2 is a schematic structural view of the cross-shaped groove of the head clamp 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 crimping tube type insulating puller, the puller includes a pull plate 1 and a head clamp 7, the pull plate 1 is an insulating pull plate using a high-strength insulating pull plate (3 tons), and the insulation pull plate It is flat design, using insulating pull plate as the main traction and installation rod, the two ends of the pull plate 1 are the wire end 4 and the tower head end 2 respectively, and the tower head end 2 has a mounting hole 3 for reliable connection of high-strength insulating pull rope , the wire end 4 and the head clamp 7 are horizontally connected by two bolts 5, as shown in Figure 2, the top of the head clamp 7 faces the direction of the pull plate 1, and a vertical groove 8 is provided on the vertical surface to the direction of the pull plate 1 Intersect with the flat groove 9 to form a cross-shaped groove, and the vertical groove is a through-open structure, so that it can ride on the vertical U-shaped hanging ring, and the flat groove can block the flat U-shaped hanging ring after tightening. The top is made of a whole piece of high-strength aluminum alloy solid material according to the characteristics and shape of crimping pipe clamps and U-rings. The reliable connection between the top and the insulating pull plate is the main component used to transfer the tension of the wire to the main traction rope.

A U-shaped clamp 6 is arranged horizontally on the upper end of the head clamp, and the pull plate is inserted and pushed into the U-shaped clamp 6 and fixed by bolts 5 .

When in use, due to the open design of the lower part of the groove of the head fixture, the force mainly acting on the U-shaped ring after it is stressed is in the flat groove of the head fixture, and the size of the groove is also in accordance with the U-shaped The outer dimensions of the ring are tailor-made.
