Compared with prior art, the invention has the advantages that：This product is simple in construction, can possess between preformed armor rods
Every the instruments such as rod removal tool, bolt-type conductor spacer removal tool, claw conductor spacer removal tool the characteristics of, meet all kinds of intervals
Rod dismounts work.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is rope ladder upper end of the present invention partial enlargement structural representation.
Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~2, a kind of maintenance rope ladder device, including rope ladder and being fixed on are overhauled on steel tower or electric pole
Guide rail 20, the transverse direction that the rope ladder includes a pair of longitudinally disposed longitudinal portions 110 and two longitudinal portions are connected to form one are stepped on
Portion 120 is stepped on, the horizontal stampeding section includes outside helical form lasso 121 and the steel wire rope 122 being arranged in lasso 121, institute
Stating longitudinal portion 110 includes the longitudinally disposed sleeve of longitudinally disposed tightrope and the more piece being fixed on tightrope, the helical form set
121 both ends are enclosed to be respectively fixedly connected with the sleeve in both sides longitudinal direction portion, often section sleeve corresponds to one helical form lasso 121 of connection,
Often save and the wind spring 131 being arranged in enclosed box body is provided with sleeve, steel cord ends and wind spring in each lasso 121
End connection, longitudinal portion is slidably matched with guide rail.
The middle part of guide rail 20 has groove, and the upper end in longitudinal portion 110 is provided with fixed block 111, and the inner side of fixed block 111 is set
Have for buckling into the pulley 112 in groove.
The outside of fixed block 111 is provided with the thread bush 113 shifted to install in short transverse, and two thread bush, which run through, lock
Tight bolt.
The lower end in longitudinal portion is provided with bottom fixed block in the present embodiment, is provided with what is shifted to install on the outside of the bottom fixed cover
Thread bush, the thread bush, which runs through, bolt.
A kind of maintenance rope ladder device is put including a kind of above-mentioned maintenance rope ladder device, including following step using what is put
Suddenly：
（1）Guide rail is arranged on Awaiting Overhaul electric pole or overhauls the upper end of steel tower, the pulley secure fit of rope ladder upper end is existed
In guide rail；
（2）Pull longitudinal portion to increase the distance in a pair of longitudinal portions along guide rail as needed and extension rope is moved towards according to guide rail
