Electric power circuit stringing device across river

Abstract

The invention discloses an electric power circuit stringing device across a river. The stringing device comprises a ground anchor mechanism used for improving stability, a support mechanism arranged on the ground anchor mechanism and an across mechanism arranged on the support mechanism. The ground anchor mechanism, the support mechanism and the across mechanism are connected with a control mechanism. The support mechanism comprises a revolving base rotatably arranged on a ground anchor plate, a telescoping rod arranged on the revolving base and a fixed seat arranged on the telescoping rod. A sleeve ring is rotatably arranged on the upper end of the telescoping rod. The outer surface of the sleeve ring is equipped with a fixed ring connected with a traction rope. A big gear wheel is fixedly arranged on the lower part of the telescoping rod. A driving motor is arranged on the ground anchor plate. A small gear wheel engaged with the big gear wheel is arranged on the output shaft of the driving motor. The driving motor is connected with the control mechanism through electrical signals. The stringing device is advantageous in that the stringing device is simple to operate, easy to recycle, safe to operate and less affected by weather.

Description

technical field [0001] The invention belongs to the technical field of electric power construction auxiliary equipment, and in particular relates to a power line stringing device across a river. Background technique [0002] Since the quality of the transmission wire, especially the high-voltage transmission wire itself, is large, and the two adjacent iron towers used to support the transmission wire have a large span, and there are charged objects, crops, trees, etc. between the two adjacent iron towers. Obstacles such as rivers, roads, buildings and structures are crossed, so erecting or dismantling transmission lines is a complex and difficult project. [0003] In the prior art, erecting or dismantling power lines usually adopts a guide rope installed between two adjacent iron towers and a pulley suspended on the guide rope and controlled by a stay wire, and in order to prevent the power line from being connected to the ground or to the above-mentioned The spanning frame...

AI Technical Summary

Problems solved by technology

Since the power line that needs to be erected or dismantled is pulled by the trolley, it needs to move between two adjacent iron towers, and in the process of moving the power line, it is supported by the spanning frame and slides on it, thus It can be seen that the spanning frame not only bears the weight of the power line, but also produces sliding friction with the power line. Therefore, no matter how strong the spanning frame is, it is easily worn by the large friction force generated by the sliding power line, especially The disassembled old power line, because of its surface similar to the sawtooth-shaped tip, is more likely to damage the spanning frame; in addition, the frictional resistance between the power line and the spanning frame will also have a greater impact on the traction components, due to the The guide rope and the pulley, as well as the pulley are affected by the wind force in the high altitude, and the guide rope and the stay wire are often entangled and the pulley is offset. After this phenomenon occurs, it is difficult for the pulley to move. In the offset state, it is necessary to overcome the frictional resistance between the power line and the spanning frame to move the power line, which will easily cause the stagnation of the power line and other phenomena, which will affect the construction process and increase the amount of maintenance. The construction cost will increase significantly

In the Chinese patent with application number 201310373308.6, an overhead line cross-laying device is disclosed, including an overhead suspension wire, a pay-off vehicle, a traction block with a driving mechanism, and a suspension wire pulley. The front end of the overhead suspension wire passes through a tensioning mechanism Connected to the fixed object in front of the spanning object, the traction block pulls the wire to be laid to move on the elevated suspension line, the suspended wire supporting wheel supports the wire and hangs on the elevated suspension wire, and the wire outlet end of the pay-off vehicle is set Wire anti-twisting device, the lower part of the traction block is equipped with a counterweight balancer; although this invention can solve the problem of wire laying, it does not solve the technical problem of river crossing operations
