Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0032] Such as Figure 1-5 As shown, the present embodiment provides a synchronous net-type telescopic boom spanning frame, which includes a main beam 1 and two spanning frame bodies 2 , and the main beam 1 spans the two spanning frame bodies 2 .
[0033] Main girder 1 comprises protective net 11, limit rope 12 (see Figure 6 ), a plurality of beam bars 13 and two telescopic arm mechanisms 14 arranged in parallel. Each telescoping arm mechanism 14 comprises the multi-layer telescoping arm unit 141 that nests successively, and the present embodiment is a four-layer structure, and the...

The invention relates to a synchronous net pulling type telescopic arm crossing frame which comprises a main beam and two crossing frame bodies. The main beam stretches across the two crossing frame bodies, the main beam comprises a protective net, a limiting rope, a plurality of beam rods and two telescopic arm mechanisms arranged in parallel, and each telescopic arm mechanism comprises multiple layers of telescopic arm units which are sequentially nested. A driving module is arranged on the telescopic arm unit on the inner layer and drives the telescopic arm unit and the telescopic arm unit on the outer layer to slide relatively, at least two cross beam rods are arranged between the two telescopic arm units, corresponding in position, on the inner layer, the protective net is hung below the cross beam rods, and every two adjacent cross beam rods on the telescopic arm mechanism are connected through a limiting rope. Compared with the prior art, the frame has the advantages of realizing rapid docking and network blocking and the like.
Description
technical field [0001] The invention relates to the technical field of power line construction, in particular to a synchronous pull-net type telescopic boom spanning frame. Background technique [0002] For the construction of high-voltage overhead lines across important facilities such as high-speed railways and high-speed lines, moso bamboo, steel pipes, and steel lattice structures are generally used to form the spanning frame, and the upper part is sealed with a protective net. These methods have certain limitations in terms of height and bearing capacity. For important large-span spanning constructions such as high-speed railways and high-speed rails, there are currently lattice-type spanning frames composed of towers and poles, which have strong stability and resistance to broken lines. With the characteristics of strong capacity, high degree of mechanized construction, and fast speed, the protective net spanning between the frames has also appeared in the form of stee...
