Abstract
The utility model discloses high-altitude power transmission lines overhauling and rotate hanging ladder with flexible, support is stepped on including rectangle ladder frame and ladder, ladder is stepped on and is supportted equidistant being fixed in rectangle ladder frame, it is characterized in that: rotating joint by fastening bolt fixing connection in the middle part of the upper ledge of described rectangle ladder frame, the pommel of the handler and upper hook that rotate joint is welded and fixed；The lower frame two ends of described rectangle ladder frame are all fixed with lower draw-bar, in the lower draw-bar at the lower frame two ends that the upper ledge two ends lengthening hanging ladder hang over rectangle ladder frame, and fix with bolt.This high-altitude power transmission lines overhauling rotates hanging ladder with flexible, owing to adding rotation joint, so the length of hanging ladder can not only be changed, and can rotate, and can lengthen to the length corresponding to electric pressure according to the difference of electric pressure；And maintainer can be allowed up and down to time on circuit at hanging ladder, it is not necessary to the action that turns due etc. are laborious, to the angle on circuit under directly can being adjusted to by health properly by hanging ladder.
Description
Technical field
This utility model relates to the improvement of a kind of high-altitude power transmission lines overhauling hanging ladder, and specifically a kind of high-altitude power transmission lines overhauling rotates hanging ladder with flexible.
Background technology
Along with the progress and development of society, electricity is closely bound up with the life of people, and electricity is transmitted by electric wire, and the accident caused due to some problems of circuit is also continuously increased, so the maintenance of high-altitude circuit is particularly significant.At present, hanging ladder usual in the maintenance of high-altitude circuit: include that support stepped on by rectangle ladder frame and ladder, ladder is stepped on and is supportted equidistant being fixed in rectangle ladder frame, it is provided with hook at the top of rectangle ladder frame, the mouth of hook is provided with fixing bolt, during use, hook is hung over the appropriate location of steel tower, seal the mouth of hook again with fixing bolt, the maintenance of high-altitude circuit can be carried out.The deficiency of this hanging ladder is: one is owing to hanging ladder can not rotate, when the position angle of maintenance is not suitable for, staff from hanging ladder up and down to the most laborious time circuit；Two is owing to because different electric pressure, hanging ladder length requirement is different, so the circuit of different electric pressure can not be overhauled simultaneously.
By retrieval, in order to overcome above the deficiencies in the prior art, the report of existing multiple hanging ladder, have have employed soft hanging ladder, can have certain anglec of rotation；Have have employed tight folded hanging ladder, and its length is solved by folding.But have not yet to see the report of the hanging ladder that can rotate.
Summary of the invention
The purpose of this utility model is to provide one can not only change length, and the high-altitude power transmission lines overhauling that can rotate rotates hanging ladder with flexible.
In order to reach object above, this utility model be the technical scheme is that this high-altitude power transmission lines overhauling rotates hanging ladder with flexible, support is stepped on including rectangle ladder frame and ladder, ladder is stepped on and is supportted equidistant being fixed in rectangle ladder frame, it is characterized in that: rotating joint by fastening bolt fixing connection in the middle part of the upper ledge of described rectangle ladder frame, the pommel of the handler and upper hook that rotate joint is welded and fixed；The lower frame two ends of described rectangle ladder frame are all fixed with lower draw-bar, in the lower draw-bar at the lower frame two ends that the upper ledge two ends lengthening hanging ladder hang over rectangle ladder frame, and fix with bolt.
This utility model is implemented also by following measure: described rotation joint, it is made up of base plate, cover plate, spheroid, clamping plate and handler, cover plate and base plate one hole of involutory rear formation, and fasten with corresponding bolt, spheroid is in hole, and the degree of depth of hole is the 2/3 of sphere diameter, and the lower end of handler is welded on the top of spheroid, clamping plate are weldingly fixed in the middle part of the diapire of base plate, the jaws width of clamping plate and the upper ledge consistency of thickness lengthening hanging ladder；Lengthened ladder fastening bolt it is provided with in the jaws of clamping plate.
The described lower frame two ends lengthening hanging ladder also be provided with lower draw-bar, so, can continue to connect next lengthening hanging ladder.
Fixing bolt it also is provided with in the jaws of described upper hook.
The beneficial effects of the utility model are: this high-altitude power transmission lines overhauling rotates hanging ladder with flexible, owing to adding rotation joint, so the length of hanging ladder can not only be changed, and can rotate, the length to the hanging ladder corresponding to electric pressure can be lengthened according to the difference of electric pressure；And hanging ladder can rotate, allow maintainer at hanging ladder up and down to time on circuit, it is not necessary to the action that turns due etc. are laborious, to the angle on circuit under directly can being adjusted to by health properly by hanging ladder.
Accompanying drawing explanation
Fig. 1 is structure front-view schematic diagram of the present utility model.
Fig. 2 is that structure of the present utility model rotates nodal axisn to section view enlarged diagram.
Detailed description of the invention
This utility model is made with reference to Fig. 1, Fig. 2.This high-altitude power transmission lines overhauling rotates hanging ladder with flexible, support 2 is stepped on including rectangle ladder frame 1 and ladder, ladder is stepped on support 2 and equidistant is fixed in rectangle ladder frame 1, it is characterized in that: in the middle part of the upper ledge of described rectangle ladder frame 1, rotate joint 4 by fastening bolt 3 fixing connection, the pommel of the handler and upper hook 5 that rotate joint 4 is welded and fixed, it is hooked on the correct position of steel tower by upper hook 5, realizes axial rotation by rotating joint 4；The lower frame two ends of described rectangle ladder frame 1 are all fixed with lower draw-bar 6, in the lower draw-bar 6 at the lower frame two ends that the upper ledge two ends lengthening hanging ladder 7 hang over rectangle ladder frame 1, and fix with bolt 8, it is achieved thereby that the prolongation of hanging ladder, to reach the maintenance requirement of different electric pressure circuit hanging ladder length.
As improvement of the present utility model: described rotation joint 4, it is made up of base plate 41, cover plate 42, spheroid 43, clamping plate 44 and handler 45, cover plate 42 and base plate 41 one hole of involutory rear formation, and fasten with corresponding bolt, spheroid 43 is in hole, and the degree of depth of hole is the 2/3 of spheroid 43 diameter, and the lower end of handler 45 is welded on the top of spheroid 43, clamping plate 44 are weldingly fixed in the middle part of the diapire of base plate 41, the jaws width of clamping plate 44 and the upper ledge consistency of thickness lengthening hanging ladder 7；Lengthened ladder fastening bolt 3 it is provided with in the jaws of clamping plate 44.
