Telescopic crossing-over frame

Abstract

The invention discloses a telescopic crossing-over frame, which is characterized by comprising a frame body, a control mechanism and an execution mechanism, wherein the control mechanism comprises a hydraulic console arranged on the frame body; the execution mechanism comprises a telescopic arm controlled by the hydraulic console and a butt connector arranged at the front end of the telescopic arm; and the telescopic arm comprises a hard network closing holding pole and a holding pole rigid connector. During the mounting process, the action is stable and reliable, a jamming phenomenon does nothappen easily, and the structure is stable and reliable; the construction workload is saved, the network closing time is shortened, and the project cost is reduced; a distortion phenomenon caused byasynchronous movement at two sides is not generated easily, and the fault possibility is reduced; the network closing speed is quick, the power output process is stable, no jamming phenomenon happenseasily, the safety and the reliability are high, a network closing big arm adopts a box-type structure, the structure is stable, network closing protection is carried out through the hard network closing holding pole, and in comparison with the traditional soft network closing, advantages of strong impact resistance, high safety and reliability are achieved.

Problems solved by technology

[0002] With the rapid development of my country's transmission line construction, the country is paying more and more attention to the safety of construction. In the construction of existing transmission lines, cross-stretching construction has the characteristics of many dangerous points and complex construction environment.

At present, the method of setting up spanning frames is generally used to protect the spanned objects. At present, the construction units design lattice type spanning frames to meet the basic functional requirements of spanning during spanning construction, but there are some problems at the same time, such as large structural mass, complicated installation, and unstable structure. , the construction is inconvenient; the hard-sealed net holding pole needs to be installed separately for a long time during installation, and the process is complicated; and it is prone to distortion during the implementation process, which increases the workload of construction personnel and is not safe enough; the power is insufficient and the power output process is not stable. prone to jamming
