Description

Replacing the hanging string combination tool

technical field

The invention relates to an electrical tool, in particular to a combined tool for replacing hanging strings.

Background technique

As we all know, insulators need to be replaced when their service life reaches the operating limit or they suffer from lightning strikes and other damages. Insulators are divided into: tension insulators, linear insulators and hanging strings according to their uses. Since the hanging strings are completely suspended in the air, there is no focus Therefore, the work of changing the hanging string becomes particularly complicated and difficult. At present, when replacing the hanging strings, workers first need to use a ladder to get down from the cross arm to the shoulder pole, and then use several lead wire sleeves and double hooks to connect, lift the shoulder pole to separate the hanging strings, and replace them. Its disadvantages are: in addition to the climbing ladder, a double hook and 3-5 lead wire sleeves are usually connected between the cross arm and the shoulder pole. There are many connecting tools and complicated procedures. In addition, the working space on the pole tower is very small, and the operation is very inconvenient; , Since the lifting device has only one stress point, after the double hooks are tightened, the shoulder pole clamp will be deflected, the spring pin will be easily stuck, and it is very difficult to take it out. It often requires another operator to cooperate on the cross arm to complete the work; third, because the shoulder pole is always under a single point of force, the operator is like standing on a seesaw in the whole operation process, which brings great pressure to the operator. The operation is inconvenient and there are unsafe factors. Therefore, it is a technical problem to be solved at present to design an easy-to-use, safe and labor-saving replacement hanging string combination tool.

Contents of the invention

The technical problem to be solved by the present invention is to provide a combination tool for replacing hanging strings that is easy to use, safe and labor-saving.

The technical scheme that the present invention solves its technical problem is:

Replace the hanging string combination tool, including the aluminum alloy ladder whose vertical rod is an empty tube, the vertical rod of the aluminum alloy ladder is equipped with round steel, the top of the round steel is welded with a connecting plate, the connecting plate and the vertical rod of the aluminum alloy ladder There are suitable bolt connection holes, and the upper part of the connecting plate and the vertical bar ladder of the aluminum alloy ladder is connected with the connecting plate by bolts. A hinge seat is welded on the upper part of one of the connecting plates, and a hanging plate is hinged on the hinge seat. There is a socket at the end of the plate, and a pin with a pin hole and a retaining ring that is suitable for the socket is welded on the upper part of the other connecting plate. The suspension ring is connected with a first suspension hook on the suspension ring, an adjustment ring is welded on the lower end of another round steel, an adjustment screw is connected on the adjustment ring, and a second suspension hook is connected on the adjustment screw.

Preferably, epoxy resin is used to fix the round steel and the vertical bar of the aluminum alloy ladder at the lower end of the aluminum alloy ladder.

Compared with the prior art, the present invention has the following advantages: first, due to the optimization of the suspension mode, the connection between the hanging point and the cross arm is stable and firm, the process of going up and down the ladder is stable and safe, and no sideways deviation occurs; second, the hook is used in the operation Directly hang the shoulder pole, no need for lead wire sleeves and lead screws, easy and convenient, easy to operate; third, due to the use of double hooks, the pole is very stable during the entire replacement process, no longer a seesaw, greatly improving the safety of the operation Safety, which ensures the safety of the operators; Fourth, during the lifting process, the shoulder pole is lifted vertically upwards, so that the pole clamps will not be skewed and the pins will be stuck, and the process of detachment and installation of the hanging string is easy and easy.
