Problems solved by technology

However, the existing spanning frame is extremely inconvenient to transport due to the large weight and volume of the whole machine, and the complicated installation process not only results in slow network closure speed, but also poor safety in the installation process
Crossing high-speed railways, power lines, highways and other projects have high safety requirements and short window time, so the inconvenience of transportation, full network closure speed and poor safety have become bottlenecks restricting the development of crossing frames

Abstract

The invention provides a spanning frame and an installation method thereof. The spanning frame includes two frame bodies, two spanning components arranged between the two frame bodies and parallel to each other, and a hard Net-sealing poles and insulating nets; the spanning assembly includes two mutually symmetrical spanning units; the spanning unit includes a working platform connected to the outside of the frame, a hydraulic support arranged on the upper side of the working platform, through the hydraulic support and connected to the The connected telescopic net-sealing boom, the docking mechanism located at the front end of the net-sealing boom and the shock-absorbing connection mechanism located at the lower side of the net-sealing boom. The spanning frame is convenient, fast, accurate and efficient to adjust; light in weight and small in size, which effectively reduces the pressure of transportation and improves the convenience of transportation; realizes unmanned automatic docking, which not only avoids the danger of high-altitude operations, but also improves the overall spanning frame. The safety of the installation, and the speed of the docking of the sealing boom is improved, and the installation speed of the spanning frame is improved as a whole.

Description

technical field [0001] The invention relates to a spanning frame, in particular to a spanning frame and an installation method thereof. Background technique [0002] With the rapid development of UHV construction in my country, during the construction of new power lines, there are more and more cases where cross-over construction is required for existing power lines, high-speed railways, and expressways. As the main construction equipment and safety measures for crossing construction, the crossing frame can effectively guarantee the safe and efficient development of the project, so the improvement of the performance of the crossing frame has attracted more and more attention. [0003] With the increase of the types of spanning frames and the improvement of performance, there are various spanning frames. However, the existing spanning frame is extremely inconvenient to transport due to the large weight and volume of the whole machine, and the complicated installation process...
