Abstract
The invention discloses an overhead transmission line insulation rope ladder, which is characterized by comprising two stand columns, a cross bar, a pothook, a steel wire rope and a steel wire rope locking device, wherein the two stand columns and the cross bar are welded to form I-shaped frame structures; through holes are formed in the stand columns, shrinkage pools are formed in one ends of the stand columns, and embossment structures are formed in the other end of the stand columns; multiple I-shaped frame structures are spliced with one another so as to form a ladder; the steel wire rope penetrates through the through holes which are formed in the stand columns and tightened through the steel wire rope locking device so as to form a rigid ladder structure; the pothook is connected with the top of the uppermost I-shaped frame structure. The overhead transmission line insulation rope ladder has the advantages that the ladder is simple in principle structure, convenient to carry and safe to use; in the overhauling process, personnel climb a conductor wire side through a composite insulator chain to use the rope ladder, thereby improving the stability degree of operating personnel in the passing process.
Description
Technical field
The present invention relates to ladder structure field, particularly a kind of overhead transmission line insulated flexible ladder.
Background technology
Straight line pole suspension insulator adopts composite insulator mostly.Due to technical requirements, in maintenance process, personnel are by using rope ladder to side of wire was under composite insulation substring.After the rope ladder using is at present connected with wire, personnel's health in upper and lower process can twist, and easily causes high falling.
Summary of the invention
The object of the invention is in order to ensure handling safety, spy provides a kind of overhead transmission line insulated flexible ladder.
The invention provides a kind of overhead transmission line insulated flexible ladder, it is characterized in that: described overhead transmission line insulated flexible ladder, comprises column 1, cross bar 2, hook 3, wire rope 4, wire rope locking device 5;
Wherein: two columns 1 and a cross bar 2 are welded into " work " cabinet frame structure; The inside of column 1 is with through hole, and one end of column 1 is with shrinkage pool, and the other end is with bulge-structure; Between multiple " work " cabinet frame structure, peg graft, form ladder; The inside of column 1 with through hole in reeve 4, and lock device 5 by wire rope and strain, form rigid ladder structure; Hook 3 is connected with the top of " work " cabinet frame structure of topmost.
Described column 1 or hook 3 are insulation materials part.
Advantage of the present invention:
Overhead transmission line insulated flexible ladder of the present invention, theory structure is simple, easy to carry, uses safety, and in maintenance process, personnel, by using rope ladder to side of wire was under composite insulation substring, have improved the degree of stability of operating personnel in the process of passing through greatly.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation:
Fig. 1 is overhead transmission line insulated flexible ladder structural representation;
Fig. 2 is " work " cabinet frame structural representation.
The specific embodiment
