Description

A kind of insulator replacement tool

technical field

The utility model relates to an insulator replacement tool.

Background technique

In order to improve the performance of equipment and avoid the situation that porcelain insulators are prone to breakage and injury during maintenance, it is necessary to replace porcelain support insulators with composite post insulators. At present, the method used in the replacement process is the crane hoisting method. In case of small-scale replacement, because the distance between the replacement equipment and the surrounding live equipment is very close, electric shock accidents or damage to adjacent equipment may easily occur; when the crane is hoisted, the adjacent intervals need to be powered off Afterwards, the operation power outage time is increased, and the power outage scope is expanded; crane hoisting also requires more equipment and personnel, and the operation is cumbersome, time-consuming and laborious.

Utility model content

The technical problem to be solved by the utility model is to provide a convenient and time-saving insulator replacement tool.

In order to solve the above problems, the provided insulator replacement tool has a structural feature that it includes a bracket on which a hoop capable of holding the pole is mounted, and an outstretched cross bar is fixed on the top of the bracket, and a hook is installed on the cross bar.

After adopting the above structure, when the insulator needs to be replaced, the bracket is connected to the wire rod through the hoop, the pulley can be hung on the hook, and the insulator that needs to be replaced or replaced can be manually sent or unloaded through the pulley with a rope; The use of the insulator replacement tool not only replaces the use of the crane, but also is convenient to use, saves the use of manpower and time-consuming replacement of insulators, and also reduces the hidden costs caused by the scope and time of power outages.

As a specific structural form of the hoop, the hoop includes a support rod fixed on the bracket, and the support rod is equipped with two semi-circular hoops that can be mounted together.

One end of the two halves of the ring clamp is hinged, and the other end is screwed together.

As an improvement of the utility model, a diagonal support is installed between the cross bar and the bracket, which can increase the support strength and stability between the cross bar and the bracket.

As a further improvement of the utility model, two hoops are arranged in parallel on the bracket to ensure the stability of the bracket.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a sectional view of line A-A in Fig. 1 .

Detailed ways

The insulator replacement tool shown in Figure 1 and Figure 2 includes a bracket 1, the bracket 1 is a steel pipe, the bracket 1 is equipped with a hoop 2 that can hold the pole tightly, and two hoops 2 can be arranged on the bracket 1, Also can be provided with a plurality of, the top of support 1 is equipped with the cross bar 3 that stretches out, and oblique support 5 is housed between cross bar 3 and support 1, and suspension hook 4 is housed on the cross bar 3. The hoop 2 includes a support rod 21 fixedly mounted on the support 1, and the support rod 21 is equipped with two semi-annular hoops 22 that can be mounted together, and one end of the two halves of the annular hoop 22 is hinged by a hinge 6, The other ends are screwed together by screws 7 .

When replacing the insulator, open the two halves of the ring clamp 22 screwed with the screw 7 to fit it on the wire pole, tighten the screw 7 to make the hoop 2 hold the wire pole tightly, and the operator hangs the pulley on the hook 4, Operators can hoist up or down the insulators used after replacement and insulators that need to be replaced through pulleys.
