Type can also be different from other manner described here using other implement, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of new intension, therefore the utility model is not limited by following public specific embodiment.
Embodiment one：
As shown in Figures 1 to 3, twin columns tight folded hanging ladder is used in a kind of power communication maintenance, it is characterised in that including：Hook 1, it is some
Individual terraced monomer 2, the hinge 3 for connecting two neighboring terraced monomer 2, workbench 4 and mounting bracket 5, the terraced monomer 2 is by two
Individual support bar 6 and crosspiece 7 are constituted, and the top of terraced monomer 2 of the top is provided with hook 1, and crosspiece 7 in position is provided with work
There is antiskid insulation rubber layer 8 on platform 4, the surface of workbench 4, and the workbench 4 is fixed on terraced monomer 2 by connecting rod 9
On, the mounting bracket 5 is removably arranged on the crosspiece of the terraced monomer bottom of least significant end.
Using the terraced monomer of gemel connection, hanging ladder is realized folder function, be convenient for carrying and store, and hinge contains locking machine
Structure, makes more to stablize during ladder expansion climbing；There is provided workbench, makes maintainer stand convenient；Mounting bracket makes hanging ladder
It can be contacted with ground, further enhance stability when hanging ladder is used；Because maintainer's height is not the same, to make everyone
All comfort and convenient during standing at work, the workbench is detachable and crosspiece of the appropriate location between the terraced support bar of monomer two
On, there is anti-skidding insulating barrier on workbench, surface is coarse textured, maintainer is difficult skidding when standing, and it is
Non electrically conductive material, further improves maintainer's operational security.
Further preferred：The connecting rod 9 includes the connecting rod I 14 being located on workbench 4 and is located on support bar 6
Connecting rod II 15, and connecting rod I 14 and connecting rod II 15 connected by pivot pin.Two connecting rods (14,15) can turn around pivot pin
It is dynamic, therefore can easily fold up, to withdraw workbench 4.
Further preferred：As shown in figure 11, the mounting bracket 5 is in " people " font, and its upper end is fixing axle 16, described
Fixing axle is provided with a series of pivot pin positioning holes 18, and the fixing axle 16 passes through the fixed hub in the terraced monomer bottom rail in end
17, and by being installed together in the insertion axle finger setting hole 18 of location axle pin 19 with bottom rail 7.Because operating environment is different, line
Cable height is inevitable variant, if the length of hanging ladder is fixed, it is possible to be at hanging erected state because hanging ladder is too short, this
When climbing shaking amplitude it is larger, be not sufficiently stable, have a strong impact on the operating efficiency and quality of maintainer, it is also possible to because of hanging ladder not
Surely occur security incident, therefore multiple pivot pin positioning holes 13 are provided with fixing axle 16, the installation of mounting bracket 5 can be adjusted
Position, to adjust the entire length of hanging ladder, enables two legs of mounting bracket 5 to be offseted with ground, it is ensured that to be hung during operation
The stability of ladder.Mounting bracket 5 is detachable, and can make the standby of multiple length, to adapt to the operation that difference in height is larger
Environment, is replaced by corresponding mounting bracket at any time as needed.
Further preferred：As shown in figure 12, the hook 1 also includes locking plate 24, and locking plate 24 is solid by fixing bolt 25
It is scheduled on hook.Fixing bolt 25 is unclamped during work high above the ground, then the ring-type that inwardly rotation formation is closed of locking plate 24 twists again
Fixed lock bolt 25, can so avoid hook from deviating from from cable, further ensure high-altitude working safety.
Further preferred：The hinge 3 contains locking mechanism.When hinge deploys, the locking mechanism can make conjunction
Page keeps 180 degree expansion without arbitrarily rotation, it is ensured that the resistance to overturning of hanging ladder.
As shown in Figs. 4-6, hinge is bayonet type, including hinge groove 10 and hing straps 11, and the hinge 3 passes through bolt 12
It is fixed on support bar 6, the hing straps 11 are provided with pivot pin positioning hole 13, the hinge 3 has set locking buckle, worked as hanging ladder
When 180 degree is deployed, buckle lockable hinge is promoted, it is to avoid arbitrarily rotated at hinge when hanging ladder is used, it is ensured that when hanging ladder deploys
Stability.
Embodiment two：
As shown in Fig. 7 to 10, the hinge of embodiment two is pulling plug formula, and remainder structure is identical with embodiment one,
Wherein hinge includes pulling plug 20, spring 21, leaf of hinge a 22, leaf of hinge b 23 and the pulling plug pivot pin 27 for connecting two leaf of hinge；
The leaf of hinge a 22 includes outer-hexagonal pulling plug shaft member 221, connection shaft I 222, and the connecting plate a for two shaft member of connection
223；The leaf of hinge b 23 includes clamping shaft member 231, connection shaft II 232, connection shaft III 235, for connecting two axles
The connecting plate b233 of part.Two connection shafts (232,235) are respectively welded at connecting plate b 233 left and right ends, and centre is formed
Opening 234, leaf of hinge a 22 connection shaft I222 is embedded at this opening, can be by two leaf of hinge (22,23) using pivot pin 27
Fit together, pulling plug 20 and spring 21 are ordinatedly connected in the through hole of outer-hexagonal pulling plug shaft member 221.Pulling plug during folded state
20 cylinder right-hand member is exposed to pulling plug shaft member 221, and now hinge is free to rotate, need to apply outside drawing during expansion to pulling plug 20
Power, now pulling plug 20 can be displaced outwardly within the specific limits and the cylinder right-hand member of pulling plug 20 is hidden in pulling plug shaft member 221, when complete
When expanding into 180 degree entirely, outside pulling force is cancelled, pulling plug can automatically reset and rebound, pulling plug cylinder exposed portion cocker spindle part
In 231, now hinge can not be rotated arbitrarily, realize self-locking function, it is ensured that stability when hanging ladder deploys.
The utility model is foldable, has saved space, is convenient for carrying and stores, more stable during climbing, safety, overhauls people
