Description

A strain tower extension ring replacement tool

technical field

The utility model relates to the field of electric fittings, in particular to a tool for replacing extension rings of tension towers.

Background technique

The pole tower of the power line is divided into a straight tower and a tension tower. The function of the straight tower is to stir up the wire, and generally only bears the vertical load; The tension load after the line is overhead, so the most dangerous part of the power line line is the tension tower.

The connection between the wire and the strain tower is realized through the extension ring and the connecting plate, the wire is fixed on the connecting plate, and the connecting ring is installed between the connecting ring and the connecting plate on the strain tower. Its purpose is to isolate the vibration and shaking between the wire and the strain tower, and protect the strain tower through self-sacrifice. Therefore, the working environment of the extension ring is very harsh. It not only has to bear huge tensile force, but also bears dynamic loads caused by vibration and shaking. Once damaged, it means power outage for maintenance, which will cause huge economic losses.

At present, a city-level transmission inspection office needs to manage a total of more than 3,000 kilometers of transmission lines (110-220kV), and there are more than 8,000 base towers in the line, of which more than 1,000 are strain towers. Inspecting and replacing extension rings is a very onerous task.

Under the premise of ensuring the stable operation of the power grid, this is a task that must be completed. The front-line workers carry out inspection and maintenance on the line all year round. The working hours are long, the work intensity is high, and it is very hard. Especially there is no special tool for changing the extension ring, only tools such as lever block and wire rope cover can be used. These tools are heavy in weight, complicated in operation, poor in operation safety and inconvenient to use, which further increases the workload of the staff on the contrary.

Utility model content

The utility model aims to provide a convenient tool for replacing extension rings of a tension tower.

The utility model adopts the following technical solutions:

A tension tower extension ring replacement tool, including a connecting part and a telescopic part;

The connecting part includes a hanging point connecting hardware and a connecting ring;

As a further solution: the thread A is set at one end of the round pipe, and the thread B is set at the other end of the round pipe.

As a further solution: the connecting ring A includes a circular ring A and a screw A fixed on the circular ring A; the screw A is threadedly connected with the round pipe.

As a further solution: the connecting ring B includes a circular ring B and a screw B fixed on the circular ring B; the screw B is threadedly connected to the round pipe.

The positive effect that the utility model produces is as follows:

The utility model is small in size and light in weight, and can reduce the load and labor intensity of workers. The traditional replacement method is to use a lever block and a wire rope. Among the weight of these tools, it is a huge consumption for the staff to climb up to the strain tower with their backs. The utility model is small in size and light in weight. The hanging point connecting hardware and connecting ring can be directly installed in the pocket, and the telescopic part can be directly held in the hand.

The utility model is more convenient to operate. When using steel wire rope, it needs to be tied to the tension tower. The wire rope is relatively hard, and it takes a lot of time to tie it to the tension tower. If it is loosely tied, it is easy to break when using it. If it is tied tightly, it is difficult to adjust the position. It is very inconvenient to use only the position of the wire rope. . When the lever hoist is in use, its two ends must be fixed, and then pulled by hand. During this process, half of the staff’s body is suspended in the air. It is difficult to exert force in this state, and the lever hoist can only be pulled bit by bit. Very low, especially the lever hoist shakes frequently and needs to change its position all the time, which is very unsafe. When using the utility model for replacement operations, the hanging point connecting hardware is directly hung on the tension tower and fixed with leveling bolts. The hanging point connecting hardware will not slide. When adjusting, you only need to loosen the leveling bolts to change the position, which is very convenient. ;In the process of pulling the connecting plate closer, you only need to insert the adjustment rod into the hole on the adjustment ring to easily turn the round tube to make the two close. In the process, pull out the adjustment rod after turning an angle, and then Insert it into another hole, and the staff can choose to lie on their stomach or squat, without moving the position, which is safer.

The utility model also optimizes the stress of the hook body and improves the service life of the hook body. In the process of use, it is difficult to ensure that the hook body and the wire are parallel, which will cause the hook body not only to bear lateral loads, but also to bear bending loads. In the process of using the leveling bolt to fix the hook body, adjusting the unscrewed length of the leveling bolt can make the hook body and the wire as parallel as possible, so that the hook body can only bear the lateral load, avoid bending, and prolong the service life.

The utility model also improves the safety of staff. During the working process, the staff rotates the round tube through the adjustment rod to achieve the purpose of making the replaced extension ring no longer bear the force. In this process, the adjustment rod increases the force arm, which can achieve twice the result with half the effort The workload can be reduced, and the work efficiency can be improved. And the adjustment ring is evenly distributed with holes, the staff can pull out the adjustment rod and insert it into other holes at any time according to the actual situation, avoiding the need to change the position at any time to turn the tool, or even work in a semi-suspension state. The safety and security of staff has been greatly improved.
