A telescopic span

Abstract

A telescopic spanning frame, characterized in that, the spanning frame includes a frame body, a control mechanism and an execution mechanism; the control mechanism includes a hydraulic console arranged on the frame body; the execution mechanism includes: The telescopic arm controlled by the hydraulic console and the docking connector arranged at the front end of the telescopic arm; the telescopic arm includes a hard-sealed net holding pole and a rigid connecting piece of the holding pole; during the installation process of the present invention, the movement is stable and reliable, and it is not easy to Jamming phenomenon occurs, the structure is stable and reliable; construction work is saved, network sealing time is shortened, and engineering costs are reduced; it is not easy to cause distortions due to asynchronous movement on both sides, reducing the probability of failure; the network sealing speed is fast, the power output process is stable, and it is not easy to occur Jamming phenomenon, high safety and reliability, the network sealing arm adopts a box-shaped structure, the structure is stable, and the network sealing protection is carried out through the hard sealing network holding pole. Compared with the traditional soft sealing network, it has strong impact resistance, safety and reliability Advanced merit.

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
