Description

A power line tower cross-arm adjustment support

technical field

The invention relates to a support device, in particular to a support device suitable for adjusting the azimuth of a power line tower cross-arm, and belongs to the technical field of power generation, power transformation or power distribution.

Background technique

In the process of erecting power lines, the installation workload of cross arms and ceramic parts on line poles and towers is very heavy, especially in the installation of cross arms and porcelain parts for branch poles, corner poles, terminal poles, double-layer lines and multi-layer poles. When working, it is often encountered that two people work on the same tower at close range for two or three hours at the same time, which is not only labor-intensive, but also has a high risk factor.

In order to solve the above problems, the electric power construction personnel adopt the operation method of completing the installation of the cross arm and porcelain parts on the ground, and then assembling the poles as a whole, thereby reducing the risk factor and improving work efficiency. However, the above-mentioned installation process cannot guarantee that the angle between the orientation of the cross-arm and the wire to be erected meets the construction design requirements, and the orientation of the cross-arm needs to be adjusted. At present, due to the lack of special support devices, the adjustment of the orientation of the cross-arm becomes a constraint Bottleneck in improving work efficiency.

Contents of the invention

The object of the present invention is to aim at the disadvantages of the prior art, to provide a power line pole tower cross arm adjustment support with simple structure, easy to use, which can reduce the work intensity and risk factor of line pole tower cross arm and ceramic parts installation, and improve work efficiency.

Problem described in the present invention is realized with following technical scheme:

A power line tower cross-arm adjustment support, which includes a first support frame, a second support frame, a screw, a nut and a ratchet wrench, the first support frame and the second support frame are arc-shaped brackets, A group of rollers are arranged on the bracket, and the rollers are evenly arranged radially along the arc-shaped bracket. One end of the first support frame and one end of the second support frame are hinged by a pin, and their other ends are connected and locked by a screw and a nut. .

The above-mentioned power line pole tower cross arm is adjusted and supported. One end of the first support frame is provided with a first support frame hinge seat, and the other end is provided with a first locking seat. The outer end of the first locking seat is provided with a screw through groove. .

The above-mentioned power line pole tower is adjusted and supported. One end of the second support frame is provided with a second support frame hinge seat, and the other end is provided with a second locking seat. The second locking seat is provided with a stepped hole. A self-aligning bearing is arranged at the large-diameter end of the stepped hole.

The cross arm of the power line pole tower is adjusted and supported, and the screw rod and the ratchet wrench are integrated.

The first support frame and the second support frame of the present invention are hinged together through pin shafts, and when it is necessary to adjust the azimuth of the cross-arm of the line pole and tower, the arc-shaped brackets of the first support frame and the second support frame form a hollow collar , and set it on the outside of the cylinder of the line pole tower, and then use the ratchet wrench to make the screw nut cooperate and lock; because the present invention is provided with rollers on the first support frame and the second support frame, the disassembled line pole tower cross arm can be placed on the rollers Rotate easily to the set angle on the plane, and then fix the cross arm of the line pole tower with the cylinder of the line pole tower; the present invention sets a self-aligning bearing on the second locking seat of the second support frame, which cooperates with the screw The adjustment of the direction of the screw rod can be realized; the present invention sets a screw rod through groove at the outer end of the first locking seat of the first support frame, and the screw rod with the integrated structure of the ratchet wrench can be assembled with the nut first and then enter the screw rod through groove. It is fastened with the nut, or the nut can be removed and inserted into the screw channel, and then the nut can be installed. In a word, the present invention has the characteristics of simple structure and convenient use. It can not only realize the adjustment of the position of the cross-arm of the line pole tower, but also reduce the labor intensity of the operator and the risk factor of high-altitude operation, and improve the work efficiency.
