The stated problem is solved, and the technical result is achieved by creating and using a device for straightening deformed traverses on the supports of overhead power lines, characterized in that it consists of a base made of a pipe with two hooks welded to it on one side: one for gripping the lower shelf deformed corner of the traverse, the second - to grab the upper shelf of the deformed corner of the traverse, and on the other - welded loops for fastening a carabiner with a rope. 2 ill.

Description

The utility model relates to devices used in the field of electric power, in particular for the repair of overhead power lines (hereinafter referred to as OHL).

As a result of accidents that resulted in breaks in power lines and deformation of traverses on supports, there is a way to repair overhead power lines and restore traverses using special equipment [Aerial towers (automatic hydraulic lifts) based on GAZ, KAMAZ, MAZ, Ural (Electronic resource.URL: http:/ /www.cdminfo.ru/spetstehnika/stroitelnaya-tehnika/6.1.avtogidropodemniki.html)]. The overhead line maintenance technician loads the equipment needed for repairs into the cradle of the aerial platform, then the driver of the aerial platform drives up to the overhead power line support and installs the equipment to carry out the work. The overhead line maintenance technician, while in the cradle, dismantles the deformed cross-arm from the overhead power line support for its further repair and installation back on the overhead power line support.

The main disadvantage of the existing method is:

the need to attract additional equipment due to the lack of access roads to the site (excavators, manipulators, dump trucks) for laying beds and backfill, access roads, which significantly increases the time for restoration of overhead power lines;

long time to restore overhead power lines.

The purpose of the utility model is to optimize the work associated with the absence of the need to dismantle the deformed crossarm from the overhead power line support.

The technical result is the possibility of straightening a deformed traverse without dismantling it from the overhead power line support and using special equipment.

The stated problem is solved, and the technical result is achieved by creating and using a device for straightening deformed overhead power line cross-arms.

The claimed device for straightening deformed cross beams without dismantling them from the overhead power line support is explained using:

fig. 1 - device at work;

fig. 2 - side view;

fig. 3 - photograph.

The design is a device made of a base (1), consisting of a pipe with special hooks (2) welded on one side, bent at a certain angle to capture a deformed traverse (3), and on the other - welded loops (4) for attaching a carbine (5) with rope (6).

Installation of the device on the deformed traverse (3) of the overhead power line is carried out in the following sequence.

An overhead power line electrician climbs on manholes to the support (7) of the overhead power line, another installer located below attaches a device (1) to the rope (6) for straightening deformed cross-arms (3). The fitter, located on the support (7), lifts the device (1) and installs it on top of the traverse (Fig. 1), then the overhead power line electrician, located on the ground, pulls the rope (6) down. With a pipe length of 1600 mm and the weight of the second fitter, a lever is obtained with a fulcrum on the edge of the traverse (3), and due to this, a force is created sufficient to straighten the traverse (3). Installation of the device on overhead power transmission poles takes no more than two minutes.

Working drawings (Fig. 2), strength calculations and a prototype were made for the claimed device, which was successfully tested during the restoration of lines after adverse weather conditions on the VLZ-10 kV feeder “Gryazovets-Buy” in the Gryazovets LPUMG LLC Gazprom Transgaz Ukhta .

The claimed device for straightening deformed cross-arms on overhead power transmission poles allows two electricians to carry out repairs, without the use of special equipment. The device is easy to transport, quickly installed and convenient to use.

Claims (1)

A device for straightening deformed traverses on overhead power line supports, characterized in that it consists of a base made of a pipe with two hooks welded to it on one side: one for gripping the lower flange of the deformed corner of the traverse, the second for gripping the upper flange of the deformed corner traverses, and on the other - welded loops for fastening a carabiner with a rope.
