Description

An overhead low-voltage cable binding pulley

Technical field

The utility model relates to the construction field of overhead low-voltage cables in distribution station areas, in particular to an overhead low-voltage cable binding pulley.

Background technique

At present, it is more common to lay low-voltage cables overhead in the distribution station area. The higher the overhead crossing height, the more difficult the construction is, mainly because it is inconvenient to use ladders or pedals due to terrain restrictions such as streets, houses, and rivers. Binding of low-voltage cables and steel strands generally adopts traditional construction methods. After binding the low-voltage cables and the pre-installed steel strands with aluminum wire, the low-voltage cables are pulled forward, and the low-voltage cables are pulled while binding. Sliding the aluminum wires forward along the steel strands is easy to wear the aluminum wires, which is time-consuming and labor-intensive, and poses a great potential safety hazard.

Utility model content

In order to overcome the shortcomings of traditional construction methods, reduce construction difficulty, ensure construction safety and facilitate on-site installation, the utility model provides an overhead low-voltage cable binding pulley.

The technical scheme adopted by the utility model to solve the technical problem is: tighten the U-shaped hoop on a pulley center shaft of a suitable size with bolts, the U-shaped hoop is made of stainless steel, and the U-shaped hoop is made of U-shaped hoop The fixed part of the hoop is composed of the movable part of the U-shaped hoop. The fixed part of the U-shaped hoop and the movable part of the U-shaped hoop are connected by a rotating pin shaft. The rotating pin shaft is in the middle of one side of the U-shaped hoop. The movable part of the U-shaped hoop can rotate a certain angle to the outside with the rotating pin as the center. The total length of the U-shaped hoop is 30cm and the width is 3cm. A φ10mm round hole is machined at a suitable position at both ends of the U-shaped hoop, and A ring is welded at the lower end of the U-shaped hoop, so that a kind of overhead low-voltage cable binding pulley is formed.

During construction, first set up the spanning steel strand, open the movable part of the U-shaped hoop on the overhead cable binding pulley provided by the utility model, ride the pulley on the steel strand, and then put the cable into the U In the groove of the U-shaped hoop, fasten the movable part of the U-shaped hoop and tighten the screws. After the U-shaped hoop and the cable are tied together with aluminum wire, the low-voltage cable is pulled forward, and the pulley is added while pulling. , so that the pulley slides forward along the steel strand until all the low-voltage cables are pulled.

The beneficial effects of the utility model are: because the pulley is rotating, the frictional resistance is small when pulling, the load-bearing capacity is large, it is not easy to wear, the construction is convenient, the binding is easy, the traction is easy, and there is no need for personnel to use tools such as ladders or pedals on the overhead steel stranding. Work online to achieve safe and efficient goals.
