Abstract

The utility model refers to structures used in the electric power industry, in particular during the repair of overhead power lines (hereinafter referred to as overhead transmission lines). The task of the utility model is to optimize the work associated with the installation of equipment on supports and restoration of overhead transmission lines. The technical result is the ability to mount and dismantle equipment on The problem is solved, and the technical result is achieved by creating and using a device consisting of a U-shaped base welded from a steel corner, reinforced with stiffeners welded to it from a steel strip, while on top of the structure on both sides stems were made, to which a steel circle was welded to install a chain hoist block, under which stiffeners were also welded.

Description

The utility model refers to structures used in the electric power industry, in particular, during the repair of overhead power lines (hereinafter - OHTL).

There is a method of installation, equipment on overhead transmission line supports using special equipment [1]. An overhead power line service technician loads the equipment into the cradle of the aerial platform, then the aerial platform driver drives up to the overhead transmission line support, installs the equipment for the work. An overhead power line service technician, being in a cradle, assembles equipment on a support, in the same way, work is carried out to dismantle equipment from overhead transmission line supports.

The main disadvantage of the existing method is the need to attract additional equipment (excavators, manipulators, dump trucks) for laying bedrock and dumping areas, due to the lack of access roads to overhead transmission lines, which significantly increases the installation time of equipment when restoring overhead transmission lines.

The task of the utility model is to optimize the work associated with the installation of equipment on supports and the restoration of overhead transmission lines.

The technical result is the ability to mount and dismantle equipment on overhead transmission line supports without the use of special equipment.

The task is solved, and the technical result is achieved by creating and using a device consisting of a U-shaped base welded from a steel corner, reinforced with stiffeners welded to it from a steel strip, while on top of the structure, on both sides, outriggers are made to which a steel a circle for installing a chain hoist block, for the fastening of which stiffeners are also welded.

The declared device for mounting and dismantling equipment on the overhead power transmission line supports is explained with the help of:

fig. 1 - device design;

fig. 2 - a method of installing the device on the overhead transmission line support.

The design of the device is made in the form of a U-shaped headband (4) temporarily mounted on the overhead transmission line support with a mount for a removable chain hoist block (5). The structure (4) consists of a base welded from a steel angle (6), reinforced with stiffeners (7) welded to it from a steel strip 40 × 4. On top of the structure (4), outriggers (9) are welded on both sides, to which a steel circle (8) is welded to install the pulley block (5). Stiffeners (10) are also welded under the block of the chain hoist (5). A rope (3) is attached to the pulley block (5), then the fitter climbs onto the overhead power line support and installs the equipment (2).

Installation of the device on the overhead transmission line support is carried out in the following sequence.

The first electrician of the overhead power line rises on manholes on the support (1) of the overhead power line, the second electrician of the overhead power line, located at ground level, attaches to the rope (3) the structure (4) of the device for mounting and dismantling equipment on the supports of the overhead power line. The first electrician of the overhead transmission line, located on the support (1), lifts the structure (4) of the device and installs it on top of the support (1). Then, on the structure (4), the first electrician of the overhead transmission line hangs the pulley block (5) and attaches a rope (3) to it. Further, the second electrician of the overhead transmission line mounts the equipment (2) to the rope (3) and then to the support (1). The installation time of the device for mounting and dismantling equipment on the overhead transmission line supports takes no more than five minutes.

For the declared design, working drawings, strength calculations were made and a prototype was made, which was successfully tested during the installation of equipment on supports and restoration of overhead transmission lines on OHL 3-10 kV feeder "SRTO-Sever" in Gryazovetsky LPUMG of Gazprom transgaz Ukhta LLC. In this regard, the device declared by us meets the criterion "Industrial applicability".

The claimed device for mounting and dismantling equipment on overhead transmission line supports allows mounting and dismantling of equipment by electricians of overhead transmission lines without the use of special equipment. The device is easy to transport, quick to install and easy to use.

Claims (1)

A device for mounting and dismantling equipment on the supports of overhead power lines, characterized by the fact that it consists of a U-shaped base welded from a steel corner, reinforced with stiffeners welded to it from a steel strip, while on top of the structure on both sides there are offsets to which a steel structure is welded for hanging the block of the chain hoist, under which stiffeners are also welded.
