Fig. 2 is a schematic structural diagram of the bump of the present invention.

In the figure: 1. a first side plate; 2. a second side plate; 3. a ladder stop; 4. an outer cylinder; 5. an inner cylinder; 6. a spring plate; 7. salient points; 8. positioning holes; 9. and (5) reinforcing ribs.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a ladder type cable bridge comprises a U-shaped first side plate 1, a U-shaped second side plate 2 and a plurality of ladder bars 3 which are distributed between the first side plate 1 and the second side plate 2 at equal intervals and can adjust the length; the ladder shelves 3 include barrel 4 and barrel 5 in the hollow outside the hollow, and outer barrel 4 and interior barrel 5 are the stainless steel barrel, and the internal diameter of outer barrel 4 equals with the external diameter of interior barrel 5, and the one end fixed connection of outer barrel 4 is on the curved surface of the lower part of first curb plate 1, and the one end fixed connection of interior barrel 5 is on the curved surface of the lower part of second curb plate 2, and the other end cartridge of interior barrel 5 is in outer barrel 4.

When the cable is laid, the cable moves on the surface of the ladder rail 3 by the rolling of the outer cylinder body 4 and the inner cylinder body 5, the contact surface of the cable surface and the ladder rail 3 is changed into rolling friction from original sliding friction, so that the friction force is reduced, the damage caused by the easy galling of the cable surface is avoided, the surface layer protective layer of the cable is protected, and the potential safety hazards such as electric leakage and short circuit caused by the damage of the cable surface layer are avoided.

A spring piece 6 is arranged in the barrel body of the inner barrel body 5, a salient point 7 is connected to the spring piece 6, a plurality of penetrating positioning holes 8 are formed in the position, opposite to the salient point 7, of the outer barrel body 4, and the distance between every two adjacent positioning holes 8 is 10-20 mm. The internal surface of first curb plate 1 and second curb plate 2 all is equipped with strengthening rib 9, and first curb plate 1,

second curb plate

2 and 3 surfaces of ladder shelves all are equipped with the galvanizing coat.

When the bridge is normally used, the salient points 7 extend out of the positioning holes 8 under the action of the spring pieces 6, and part of the salient points 7 are positioned outside the outer cylinder 4, so that the relative movement of the outer cylinder 4 and the inner cylinder 5 is limited; when the length of ladder shelves 3 need be adjusted, only need press down bump 7, make that be located the outside part of outer barrel 4 bump 6 withdraw in outer barrel 4, then with interior barrel 5 slide in outer barrel 4, after barrel 5 takes bump 7 to move the locating hole 8 of suitable position together when interior, bump 7 can stretch out locating hole 8 again under the effect of spring leaf 6, thereby the length of ladder shelves 3 has been changed, realize crane span structure width adjustable purpose, satisfy the laying requirement of not unidimensional and quantity cable in the actual installation, the utilization ratio of ladder formula cable bridge has been improved.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
