Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

referring to fig. 1 to 4, a clip connecting structure for a main cable of a suspension bridge includes:

the anti-skidding clamp comprises an upper half clamp 1, wherein anti-skidding lines are arranged on the inner surface of the upper half clamp 1, upper flanges 2 are arranged on two sides of the upper half clamp 1, upper connecting holes are formed in the flanges, upper step grooves 4 are formed in the areas of two ends of the upper half clamp 1, and a rubber pad 5 is connected in the upper step grooves 4;

the anti-skidding sling clamp comprises a lower half clamp 6, wherein anti-skidding threads are also arranged on the inner surface of the lower half clamp 6, lower flanges 7 are arranged on two sides of the lower half clamp 6, lower connecting holes 3 are formed in the lower flanges 7, lower step grooves 9 are formed in the areas of two ends of an upper half clamp 1, a rubber pad 5 is also connected into each lower step groove 9, a lower support plate 10 for connecting a sling is further fixed on the lower half clamp 6, and a through water drainage hole 11 is formed in each lower support plate 10;

and the two winding convex parts 12 are connected to the main cable 13, and correspond to the upper step groove 4 and the lower step groove 9 respectively.

The process of the utility model is that when the main cable 13 is connected with the cable clamp, the winding bulge piece 12 is connected on the main cable 13, after the connection of the winding bulge piece 12 is completed, the upper half clamp 1 and the lower half clamp 6 are connected, wherein the rubber pad 5 of the upper step groove 4 of the upper half clamp 1 is aligned with the winding bulge piece 12, the rubber pad 5 of the lower step groove 9 of the lower half clamp 6 is also aligned with the winding bulge piece 12, and finally the upper flange 2 and the lower flange 7 are fastened through a bolt and a nut, by adopting the structural form, the cable clamp can be further limited between the two winding bulge pieces due to the effect of the winding bulge piece 12, meanwhile, the rubber pads 5 on the upper step groove 4 and the lower step groove 9 can generate deformation due to flexibility, and can be tightly pressed on the winding bulge piece 12 through deformation when being connected with the winding bulge piece, the fastening performance of the cable clamp can be further enhanced, in addition, because the lower support plate 10 for connecting the sling is fixed on the lower half clamp 6, the drainage holes 11 formed in the lower support plate 10 can effectively drain rainwater, and the corrosion of the sling clamp caused by rainwater deposition is prevented.

Further, the winding protrusion 12 is made of a winding steel wire. Specifically, the winding protrusion 12 of the utility model adopts a winding steel wire, which is more convenient for binding, and meanwhile, after the winding steel wire is wound, the surface of the winding steel wire is not flat, and undulation exists between the steel wire and the steel wire, so that when the rubber pad 5 is pressed, the rubber pad 5 can deform along with the undulation, the biting force is tighter, and the cable clamp is not easy to fall off.
