Device for hoisting equipment on overhead power line poles and its installation tools

Abstract

The invention discloses a device for hoisting equipment on an overhead power line pole and an installation tool thereof, belonging to the field of electric power construction. The device includes at least one cross arm, and one end of the cross arm is fixedly connected with a pulley for installation and hoisting The pulley fixing device, the other end of the cross arm is fixedly connected with a first stay wire hoop, and the cross arm is installed on the electric pole through the first stay wire hoop. The installation tool includes elastic clips, a number of climbing wheels are evenly distributed on the inside of the elastic clips, and the rotation of the climbing wheels drives the elastic clips to climb the pole; The locking device of the first cable hoop. The device is not affected by the geographical environment, especially in rural areas, which avoids disputes caused by large-scale machinery entering the site, improves construction efficiency, and reduces construction costs; the installation tool completes the installation of the device without manual climbing, avoiding Safety hazards caused by artificial climbing installation.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a device for hoisting equipment on an overhead power line pole and an installation tool thereof. Background technique [0002] In the field of electric power, power equipment such as transformers, switches, and lightning arresters need to be installed on reinforced concrete poles to achieve normal and stable operation of power lines. In power construction, equipment on poles is installed everywhere. When manpower cannot be installed, It is often necessary to use machinery for hoisting, such as a crane, etc., but limited by the traffic environment, in places where the crane cannot reach, it is necessary to manually pull the switch to the installation position using a pulley block. [0003] When the equipment is hoisted through the pulley block, the pulley block is hung on the cross arm of the original electric pole. During the construction process, it is found ...

AI Technical Summary

Problems solved by technology

[0003] When the equipment is hoisted through the pulley block, the pulley block is hung on the cross arm of the original electric pole. During the construction process, it is found that if the fixed pulley on the pole is close to the electric pole, the switch will touch the electric pole during the rising process; if the pole The upper fixed pulley is far away from the pole, which solves the phenomenon of bumping the pole, but the cross arm will be inclined downward under the force. After installation, the cross arm needs to be restored, which is time-consuming and laborious
