Adjustable auxiliary device for installation of cross arm

Abstract

The invention discloses an adjustable auxiliary device for the installation of a cross arm, and the device comprises a locking clamping rod, a first clamping plate and a second clamping plate. One side of the first clamping plate and one side of the second clamping plate are provided with clamping arcs which are semicircular and can be matched with each other to form a circle. The locking clampingrod is provided with a connecting rod in an inclined hinged manner, and an end part of the connecting rod is hinged to a handle. The centers of the clamping arcs are respectively provide with movableclamping blocks, and the two movable clamping blocks are respectively provided with movable push frames. The interior of each movable push frame is provided with a threaded push rod in a sleeved manner, and one end of each threaded push rod is disposed on the corresponding movable clamping block. According to the invention, the device is provided with the first and second clamping plates which are matched with each other, and can form a dead point to clamp an electric rod, thereby forming a fixed placement platform, greatly reducing the labor intensity of a worker, facilitating the shorteningof the installation time, improving the work efficiency, facilitating the improvement of the installation quality, and reducing the potential safety hazard. Moreover, the device is provided with themovable clamping blocks, and the device can be suitable for electric rods with different diameters, is wide in application range, and is good in practicality.

Description

technical field [0001] The invention relates to an installation tool for an accessory of a power line construction frame, in particular to an adjustable auxiliary device for cross-arm installation. Background technique [0002] The cross arm is an important part of assembling the power tower. In the erection of power lines, the top of each concrete pole needs to be installed with a corresponding cross arm to support the overhead line. Generally, it is installed at a distance of 300-800mm from the top of the pole. According to the type and use of the concrete pole, it can be divided into single poles. Cross-arm, anti-expansion cross-arm, various types of cross-arm, ranging from 10kg to 30kg. When installing the cross-arm, the installation worker supports the cross-arm with the safety belt around the waist, the waist is under heavy force, and the labor intensity is high. The tools required for installing the cross-arm are carried on the back of the installer, which can easily...

AI Technical Summary

Problems solved by technology

When installing the cross-arm, the installer supports the cross-arm with the safety belt around the waist. The waist is under heavy force and the labor intensity is high. All the tools required for installing the cross-arm are carried on the back of the installer, which can easily cause the installation worker to be physically exhausted. All tools and installation are supported by the installer manually, which not only takes a long time for installation and low work efficiency, but also has poor installation quality and low safety performance
