Abstract
The utility model discloses a kind of installation steel tower annex special ladder, it comprises cat ladder; The top of described cat ladder is provided with metal ring; Described metal ring is socketed by U-shaped ring and wire rope; The stull of described cat ladder is provided with Anti-slip cover; The surface of described Anti-slip cover is provided with transverse rubber striped.The utility model effectively solves prior art and there is inconvenient, the dangerous high technical problem of use.
Description
technical fieldthe utility model belongs to transmission line construction equipment technical field, relates to a kind of installation steel tower annex special ladder.
background technologyalong with the expanding day of electrical network, require more and more higher to construction quality and operating efficiency, need to use cat ladder when steel tower carries out installation and repairing, constructor from top to bottom carries out installing, dismantling on cat ladder.At present, the cat ladder used welds two metal hangers on the top of ladder, to hang on the cross-arm of steel tower when using, workman's climbing gets on to carry out operation, although this cat ladder structure is simple, but because the size of hook, height there are differences, cause cat ladder discontinuity, easily meet with into cat ladder discontinuity above people steps down in and deformation occurs, using inconvenience, and hook is provided with opening, there is the hidden danger of unhook in the mode of this mounting.
summary of the inventionthe purpose of this utility model solves prior art to there is inconvenient, the dangerous high technical problem of use, provides a kind of and install steel tower annex special ladder, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model one installs steel tower annex special ladder, and it comprises cat ladder; Its main points are that the top of described cat ladder is provided with metal ring; Described metal ring is socketed by U-shaped ring and wire rope; The stull of described cat ladder is provided with Anti-slip cover.
The surface of described Anti-slip cover is provided with transverse rubber striped.
The mode that the utility model adopts wire rope to be fixed by socket, two montant uniform force of cat ladder, and wire rope can not come off in cross-arm, the hazards existing for cat ladder landing are stopped, when the Anti-slip cover that the stull of cat ladder is arranged can prevent workman's operation, sole steps on cunning, has ensured the safety of operating personnel.
accompanying drawing explanationfig. 1 is the utility model structural representation;
Fig. 2 is the Anti-slip cover cross section structure for amplifying schematic diagram in cat ladder stull.
In figure 1, wire rope 2, U-shaped ring 3, metal ring 4, Anti-slip cover 5, cat ladder
detailed description of the inventionaccording to Fig. 1 and Fig. 2, the utility model one installs steel tower annex special ladder, and it comprises cat ladder 5; The top of described cat ladder 5 is provided with metal ring 3; Described metal ring 3 is socketed with wire rope 1 by U-shaped ring 2; The stull of described cat ladder 5 is provided with Anti-slip cover 4; The surface of described Anti-slip cover 4 is provided with transverse rubber striped.
During construction, workman climbs on the cross-arm of steel tower by modes such as climbers, wire rope is hung over steel tower cross-arm correct position, with U-shaped ring, the metal ring on cat ladder is connected with the rope sling of wire rope, form the interim vertical cat ladder hung on cross arm of tower, operating personnel from top to bottom climbs on cat ladder, selects correct position to carry out annex installation.
