Abstract

The invention discloses a spanning frame, which comprises four tower columns arranged on both sides of the spanning line and located at the four corners of a rectangle, an aluminum tube support assembly spanning both sides of the line and connected to the tower columns at both ends, parallel to the line and The cross arm connecting the top of the tower and the insulation net between the four towers and spanning the line, the tower includes a chassis, a number of tower sections above the chassis, and the upper and lower ends of the tower are arranged on the upper part of the tower and the tower section The connected four-way flange, the general hanging point arranged on the top of the tower column, and the guy wire bracket arranged above the general hanging point. The main structure of the docking device of the present invention is a docking sleeve and a lock bolt. The butt joint ends of the first aluminum tube and the second aluminum tube are docked in the docking sleeve and locked by the lock bolt. Therefore, the structure of the docking device is simple and the docking is reliable.

Description

technical field [0001] The invention relates to the construction technology of transmission lines, in particular to spanning frames. 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] The Chinese invention patent with the application number 201810554614.2 disclosed on October 12, 2018 a spanning frame docking device and a spanning frame, including a plug-in part and a receiving part; the plug-in part includes a first flange and a connection with the first A male butt joint con...
