RU167281U1 - ELECTRIC TRANSMISSION SUPPORT TRAILER - Google Patents

Abstract

The transverse support of the overhead power transmission line, made of a metal profile of an angular cross section along the edges of which holes are made, designed to install supports of a round metal profile for mounting support insulators; in the middle of the said metal profile, a support of a circular metal profile is fixedly fixed for mounting a vertical insulator, characterized in that it further comprises a metal plate with a hole fixed motionless in the middle of the metal profile of an angular cross section.

Description

The utility model relates to the field of work safety in the electric power industry, and specifically, to the construction of the crosshead of an overhead power line support, which can mainly be used on overhead power line supports, which are difficult to access on specialized vehicles during repair and maintenance.

For the prototype, the well-known crosshead of the overhead power line support made of an angular profile was selected, along the edges of which holes were made for installing support insulators, and a fixed support made of a round metal profile was fixed in the middle of the profile for installing a vertical insulator. The well-known traverse is designated TN-1 in the collection of typical designs of products and units of buildings and structures, series 3.407.1-136 Reinforced concrete poles of 0.38 kV overhead lines, issue 1. Approved by protocol No. 24 of the USSR Ministry of Energy dated 03.10.1985.

This well-known crosshead of an overhead power line support does not contain any elements for attaching protective equipment working from a fall from a height.

A technical problem is the safety of work performed at heights.

The solution to this technical problem is provided by performing a traverse of the overhead power line support from the angular cross-section profile and fixing fixedly in the middle of the traverse of the plate with a hole for attaching protective equipment working from falling from a height. This plate serves as an anchor point for attaching fall protection from a height. The specified plate is fixed, for example, by welding or detachable threaded elements.

The technical result of this utility model is the functional expansion of the use of the yoke due to the addition of an element to the yoke structure for attaching fall protection devices from a height working on a support.

In FIG. 1 shows the crosshead of an overhead power line support with an anchor point for attaching fall protection devices from a height, a general view of FIG. 2 is a plan view.

The traverse of the overhead power line support with an anchor point for attaching fall protection from a height includes:

- a metal profile of an angular cross-section 1, along the edges of which holes are made, designed to install supports of a round metal profile 3 for attaching support insulators (not shown in Fig.);

- in the middle of the profile 1 fixed support 4 of a round metal profile for mounting a vertical insulator (not shown in Fig.);

- the crosshead is attached to the support of the overhead power line with a clamp 2;

- in the middle of the metal profile 1, the plate 5 is fixedly fixed, it is fastened in the middle so that the shoulder is not created when the load is applied to it, it has an opening of the required diameter 6 for fastening the protective equipment when working at height, it is an anchor point in the safety system when lifting to a height.

An anchor point on the traverse of the overhead power line support with an anchor point for attaching fall protection devices from a height must withstand a load of 22 kN without breaking.

In the presented example, all the details of the traverse of the overhead power line support with an anchor point for attaching fall protection devices from a height are made of steel and, in cases not mentioned above, are fixedly connected by detachable threaded elements or other known methods, or one-piece - by welding. The presence of an anchor point for attaching protection from falling from a height on the crosshead allows you to climb to the support of an overhead power line using a ladder or manholes, observing the necessary safety measures when working at height.

Lifting to the support with a ladder or manholes is necessary for supports to which it is difficult to access on specialized vehicles during repair and maintenance, and it is also impossible to install a flexible anchor point on the support to attach protection from falling from a height. Therefore, the installation of a traverse with an anchor point allows you to ensure the safety of work at heights.
