A spanning frame docking device and a spanning frame

Abstract

The invention provides a spanning frame butt joint device and a spanning frame, comprising an inserting part and a receiving part; the inserting part comprises a first flange and a male butt joint coaxially connected with the first flange; the receiving part comprises a first Two flanges and a sleeve coaxially connected with the second flange; the sleeve is provided with interconnected elastic parts, transition pieces and concave butt joints in sequence from the bottom to the opening; the sleeve includes sequentially arranged from the bottom to the opening and a coupling section with a decreasing inner diameter, a locking section for preventing the separation of the male butt joint and the female butt joint, and a limiting section for restricting the outward movement of the female butt joint; the side wall of the transition piece A buckle hole perpendicular to its axial direction is provided on the top, and a spring buckle is provided in the buckle hole; a secondary buckle hole with the spring buckle is provided at the joint section of the sleeve near the bottom. This device effectively prevents the boom from being disengaged during operation errors or accidental impacts; realizes accurate and fast unmanned docking, and improves the safety and efficiency of docking.

Description

technical field [0001] The invention relates to a spanning frame docking technology, in particular to a spanning frame butting device and a spanning frame. Background technique [0002] With the rapid development of UHV construction in my country, in the process of building new power lines, there are more and more situations that require cross-over construction of existing power lines, high-speed railways, and expressways. As the main construction equipment and safety measures of the spanning construction, the spanning frame can effectively ensure the safe and efficient development of the project, so the improvement of the performance of the spanning frame has attracted more and more attention. [0003] In recent years, with the development and promotion of propulsive and telescopic spanning frames, there are more and more working conditions that require the connection of the double-sided meshing booms of the spanning frame during construction. The safety is poor, the docki...

Problems solved by technology

[0003] In recent years, with the development and promotion of push-type and telescopic spanning frames, there are more and more working conditions that require the docking of the two-sided sealing arms of the spanning frame during construction, while the docking of the existing spanning frames requires on-site high-altitude operations. Poor safety, high docking difficulty, long construction time, difficult to meet the window period requirements for crossing high-speed rail and lines; the safety, reliability, and docking speed of crossing overhead docking devices have become bottlenecks restricting the development of crossing frames
