Problems solved by technology

However, due to the disadvantages of poor safety, heavy machine weight, low degree of automation, and slow speed of closing / dismantling the network, the traditional spanning frame cannot meet the construction needs. The research on high new spanning frame is one of the improvement directions of spanning construction
[0003] The invention patent with the application number 201810554650.9 discloses "a spanning frame and its installation method". The pressure of the oil cylinder is not easy to adjust, the vibration is large during the movement, and the accuracy is not guaranteed. When the telescopic arms on both sides are docked, there is no special observation equipment, and personnel need to climb up to observe. The docking operation is difficult and dangerous, and its sealing arm The material cannot meet the impact resistance requirements of the telescopic spanning frame

Abstract

The invention discloses a full-automatic net blocking / dismounting telescopic crossing frame which comprises two frame bodies symmetrically and correspondingly arranged and equal in height, two spanning assemblies arranged between the frame bodies and located on the same horizontal plane, and a hard net blocking holding pole and an insulating net arranged between the spanning assemblies. The spanning assembly comprises two mutually symmetrical spanning units, and each spanning unit comprises a working platform connected with the outer side of the frame body, an adjusting support arranged on the upper side of the working platform, a telescopic net sealing large arm penetrating through the adjusting support and connected with the adjusting support, a butt joint mechanism arranged at the front end of the net sealing large arm and an anti-twisting mechanism arranged on the lower side of the net sealing large arm; the cross section of the adjusting support is a rectangular frame, and a longitudinal component and a transverse component which form the rectangular frame are provided with ball adjusting lead screws. The adjusting precision of net blocking / net disassembling and the impact resistance strength of the spanning frame are effectively improved, manual monitoring is reduced, and full-automatic net blocking / net disassembling is achieved.

Description

technical field [0001] The invention relates to a spanning frame, in particular to a fully automatic net sealing / netting removal telescopic spanning frame. Background technique [0002] With the rapid development of UHV construction, the voltage level of new power lines and the transmission capacity of wires are gradually increasing, which puts forward higher requirements for construction technology. During the construction of transmission lines, when encountering obstacles such as existing power lines, high-speed railways, highways, and oil and gas pipelines, new power lines need to cross and cross, and the crossing has high safety requirements and a short window time. However, the traditional spanning frame cannot meet the construction needs due to the disadvantages of poor safety, heavy weight, low degree of automation, and slow speed of closing / dismantling the network. The research on Gao's new spanning frame is one of the improvement directions of spanning construction...
