Detailed Description

In order to make the technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following specific embodiments.

Example 1

Referring to fig. 1, the embodiment of the invention discloses a cable bridge capable of reducing cable damage, which comprises a first bridge 1 and a second bridge 2 which have the same structure, wherein the first bridge 1 and the second bridge 2 are vertically arranged and are fixedly connected through an angle steel frame 3, roller frames 7 capable of freely rotating are arranged on the inner side walls of the first bridge 1 and the second bridge 2, and the joint of the first bridge 1 and the second bridge 2 is connected through a sector-shaped guard plate 12.

The first bridge frame 1 and the second bridge frame 2 form vertical corners, the roller frames 7 are symmetrically arranged on the inner sides of the first bridge frame 1 and the second bridge frame 2 at the vertical corners, and the roller frames 7 are vertically arranged with the contacted cables. The roller frames 7 at the ends of the first bridge frame 1 and the second bridge frame 2 can prevent cables from being attached to the corner positions of the first bridge frame 1 and the second bridge frame 2, thereby reducing friction damage to the cables. The roller frame 7 is used for separating the cable from the corner of the bridge, so that the cable can be prevented from being directly contacted with the corner of the bridge to be rubbed and damaged, and the service life of the cable is prolonged.

Referring to fig. 1, through holes 4 matched with angle steel frames 3 are arranged on the first bridge frame 1 and the second bridge frame 2, and fixing bolts 5 are arranged in the through holes 4. One end face of the fixing bolt 5 is embedded in the inner sides of the first bridge frame 1 and the second bridge frame 2, and the other end face of the fixing bolt is arranged on the outer side of the angle steel frame 3 and is fixed through a locking nut 6.

Referring to fig. 1, a plurality of rollers 13 are provided centripetally on the sector guard plate 12. The roller 13 is arranged obliquely and centripetally, so that the cable laid on the roller 13 can slide more stably.

Example 2

Referring to fig. 2, the difference between this embodiment and embodiment 1 is that the first bridge 1 and the second bridge 2 having the same structure each include a U-shaped channel frame 8, two arc-shaped through grooves 9 that are symmetrical to each other are disposed in the middle of the inner side wall of the U-shaped channel frame 8, and the arc-shaped through grooves 9 can be more suitable for arrangement of cables, do not damage the cables, and can play a good protection effect on the cables. Two symmetrical arc rib plates 10 are arranged at the bottom in the U-shaped groove frame 8 and close to the inner side wall. The arc rib plate 10 can enhance the connection strength, connection stability and bearing strength of the integral structure of the cable bridge, and on the other hand, the cable is prevented from being scratched. The upper part of the inner side wall of the U-shaped groove frame 8 is provided with two symmetrical arc convex edges 11. The arc convex edge 11 just in time can play spacing effect, can prevent the outer parcel layer of cable along the lateral wall roll-off of vertical steel sheet to can strengthen the stability that the cable was arranged in this cable testing bridge, the convex edge adopts the arc structure moreover, is in order to prevent to cause scraping of cable to decrease.

It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only, since various other embodiments will become apparent to those skilled in the art upon reference to the following detailed description.
