Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The invention is described in further detail below with reference to the accompanying drawings:
as shown in fig. 1 and 2, according to the utility model, the anti-throwing net for the airport slide bridge is woven by steel wire ropes to form a net structure with uniform grids; the steel wire ropes are formed by twisting a plurality of strands of steel wires, the adjacent positions of the two steel wire ropes at the weaving node are respectively inserted and penetrated to form through holes, and the two steel wire ropes are mutually crossed, penetrate through the through holes on the other steel wire rope and are tensioned in opposite directions to form the weaving node; and the edge of the anti-throwing net carries out pressure head locking on the woven nodes of the steel wire rope.
In the embodiment, the anti-throwing net with the uniform grids is formed by weaving through cross, penetration and twisting among the steel wire ropes, the penetration and twisting mode at the weaving nodes is stable, and deformation cannot be generated. The tensile strength is high, and the larger the tensile strength is, the larger the twisting tensile force between the steel wire ropes is. In addition, the anti-throwing net in the weaving mode has the advantages of high elasticity, convenience in stretching and retracting and easiness in folding. Meanwhile, the interpenetration hinge mode can adapt to expansion with heat and contraction with cold of the steel wire, and is suitable for various severe weather conditions.
In the above technical solution, preferably, after one of the steel wire ropes passes through the through hole on the other steel wire rope and is tensioned, the next knitting node is knitted along the original direction of the other steel wire rope.
In the above technical solution, preferably, the perforations in the steel wire rope are formed by inserting a plurality of steel wires in the center.
In the above technical scheme, preferably, the steel wire of the steel wire rope is made of stainless steel, preferably 304 stainless steel, so that the anti-throwing net is prevented from rusting, and the durability of the anti-throwing net is ensured.
For the airport sliding bridge anti-throwing net proposed in the above embodiment, a specific weaving method thereof is described in detail below, including:
as shown in fig. 3, cutting the steel wire rope, and fixedly hanging the steel wire rope on a cross bar of a support frame according to a preset distance according to the size of the required grid;
measuring the steel wire ropes, and respectively inserting the adjacent positions of the two intersected steel wire ropes at the positions needing to be woven into through holes according to the required grid size;
the two steel wire ropes are mutually crossed and penetrate through the through hole on the other steel wire rope, and are tensioned in opposite directions to form a weaving node;
one of the steel wire ropes passes through the through hole on the other steel wire rope and is tensioned, and then the next weaving node is woven along the original direction of the other steel wire rope;
and after weaving to form the anti-throwing net with the preset size, carrying out pressure head locking on weaving nodes at the edge of the anti-throwing net.
Specifically, the mesh weaving frame adopts DN80 steel pipe as a cross bar of the support frame, and a special buckle is arranged on the cross bar to serve as a fixed point before weaving of the steel wire rope, so that the prepared woven steel wire rope is firmly fixed. The distance between the steel wire ropes can be adjusted at will by the buckles according to the mesh requirements of the meshes. The width and the length of each anti-throwing net to be manufactured can be adjusted according to actual requirements. According to specific construction requirements, 7-by-7 core or 7-by-19 core stainless steel wire ropes are adopted for weaving.
The stainless steel wire rope cutting process adopts a special wire rope cutting machine to cut the wire rope, so that the smooth and flat cutting surface is ensured, and the phenomena of burrs, looseness and the like are avoided, so that the weaving process is ensured to be smoothly carried out.
The middle point of the stainless steel wire rope is clamped and fixed at a special clamping and buckling position on the cross rod of the support frame, and each steel wire is smoothed out to prevent the steel wires from being twisted and disorderly.
In the process of weaving the steel wire rope, after the length is measured by a caliper, a threading needle is adopted to penetrate through the middle of the steel wire rope to form a through hole, another steel wire rope which is woven in a crossed mode is also penetrated through the threading needle to form a through hole, the two steel wire ropes are mutually crossed to penetrate through the through hole in the other steel wire rope, and the two steel wire ropes are oppositely tensioned and straightened at the two ends respectively to form a weaving node. And after each weaving node is woven, the steel wire rope is smoothed out again, and the operation is repeated.
As shown in fig. 4, after the anti-throwing net is woven to a required length and width, when the tail end of the steel wire net is closed, the tail ends of two steel wire ropes are inserted and twisted by using a special stainless steel pressure head, the tail end of the steel wire net is initially pressed by using special line pressing pliers under the condition of transverse twisting force, and the pressure head is finally pressed by using a special moment pressure head tool after the end is compacted. After the whole anti-throwing net is woven, the whole anti-throwing net is unfolded in the vacant ground of a warehouse, the net pieces are stretched and paved from four corners respectively, steel wire ropes are arranged on the four corners and the periphery of the net pieces after the net pieces are paved, the whole net pieces are straightened by adopting a pre-manufactured ground stretching device, the weaving size is measured again, and the size between meshes and the stress conditions of the four corners, including the stress condition of the net pieces, are recorded and measured again.
And (4) after the overall mesh is qualified by retesting, detaching the mesh, and folding and bundling the mesh by adopting a Z-shaped folding mode.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
