Device for equipment hoisting on overhead power line pole and installation tool thereof

Abstract

The invention discloses a device for equipment hoisting on an overhead power line pole and an installation tool thereof, and belongs to the field of power construction. The device comprises at least one cross arm, wherein a pulley fixation device for installing pulleys for hoisting is fixedly connected to one end of the cross arm, a first stay wire hoop is fixedly connected to the other end of the cross arm, and the cross arm is installed on an electric pole through the first stay wire hoop. The installation tool comprises an elastic clamping piece, wherein a plurality of climbing wheels are uniformly distributed at the inner side of the elastic clamping piece, and the climbing wheels rotate to drive the elastic clamping piece to climb the electric pole; and a locking device for locking the first stay wire hoop is installed on the elastic clamping piece through a connection plate. The device is free form the influence of geographical environment, and in particular, avoids the dispute caused due to the entrance of large machinery into the ground, in the countryside, increases the construction efficiency, and reduces the construction expense; and the installation tool completes installation for the device on the premise of no need of manual climbing, and avoids the potential safety hazards brought by manual 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
