Description

A ≥110kV cable rubber joint installation tool

technical field

The invention relates to cable accessories, in particular to installation accessories for various 110kV and above cable rubber joints with unlimited cable square specifications.

Background technique

Most of the connector installation tools used by cable accessories companies are not dedicated or not professional, mainly because they cannot meet the general installation of 240-2500mm² connectors, and they will produce uneven force when using them. In severe cases, it will bend the cable so that the installation cannot be completed. Therefore, these methods not only have obvious defects, but also require tools of many specifications, and it is extremely inconvenient for installers to carry tools of various specifications to go out.

Contents of the invention

Aiming at the deficiencies of the existing technology, the present invention provides a joint suitable for various specifications, which can realize aperture adjustment and tension balance, allowing the joint to be quickly and smoothly installed in place, greatly improving work efficiency. At the same time, the special tool for the joint has few specifications and can be repeated. It is a ≥110kV cable rubber joint installation tool that is easy to use and easy to carry, greatly saving transportation and installation costs.

In order to achieve the purpose of the present invention, the following technical solutions are provided: a ≥110kV cable rubber joint installation tool, which is characterized in that it includes two symmetrical clips and an adjustment block, the clips include a tail and a connecting part, and the connection between the two clips The parts are superimposed and connected to each other, and the center of the superimposed surface of the connecting part is provided with a corresponding notch. There is a bar-shaped groove behind the closed end of the groove. One end of the adjustment block is consistent with the arc of the arc groove. The width of the adjustment block is smaller than the width of the horizontal groove and is embedded in the horizontal groove. There is an adjustment hole on the surface of the adjustment block, and an adjustment bolt is arranged in the adjustment hole. One end of the adjusting bolt is inserted into the bar-shaped groove to connect with the clip flexibly, and the aperture size of the arc groove is adjusted by moving the adjusting block. There are several connecting holes corresponding to the two clips, which are fastened and connected by bolts, and the tails are symmetrical. Set with pull ring.

Preferably, the connection holes are distributed around the center of the arc groove.

Preferably, the tail is in the shape of a small trapezoid, and the connecting portion is in the shape of a large trapezoid.

Beneficial effects of the present invention: the present invention is simple in structure, wide in scope of application, easy to carry, and greatly saves production, transportation, and installation costs. Curved, greatly improving installation efficiency and accuracy.
