General in the past insulating ladder all is to be fixed on above the electric pole with iron chains, can not freely turn to.Because between the three-phase conducting wire certain space is arranged, when needing transferring position in the livewire work process, personnel must break away from electric field, leave insulated platform, fixedly chain is to proper orientation in adjustment, and personnel go up insulated platform again and operate.Like this, make hot line job efficient reduce greatly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electric pole that turns to construction insulating ladder that makes that hot line job efficient improves greatly is provided.
The technical scheme that provides according to the utility model, the described electric pole construction insulating ladder that turns to, it comprises by last terraced inner panel, go up terraced outside plate and be set up in terraced inner panel, go up the last ladder that the upper junction plate between the terraced outside plate constitutes, the descending stair inner panel, descending stair outside plate and be set up in the descending stair inner panel, the following ladder that lower connecting plate between the descending stair outside plate constitutes, the last terraced inner panel of last ladder, go up the descending stair inner panel of terraced outside plate left side section and following ladder, but descending stair outside plate left side section is hinged to the support body of folding shape by first bearing pin, the last terraced inner panel of last ladder, go up the soffit and following ladder descending stair inner panel in terraced outside plate stage casing, be provided with bracing frame between the upper surface in descending stair outside plate stage casing, right part at last terraced outside plate and descending stair outside plate is equipped with fixed mounting, the right part of going up terraced inner panel and descending stair inner panel is equipped with the adjusting mount pad, fixed mounting is hinged by the head end of second bearing pin and chain anchor ear, the end of chain anchor ear is hinged with the adjusting mount pad by second bearing pin, described chain anchor ear by some the 3rd bearing pins with some train wheel bridges, lower plate is hinged to form, be rotatably connected to the elasticity roller on the 3rd bearing pin between train wheel bridge and the lower plate, be in being hinged on the transition mount pad of the 3rd bearing pin in chain anchor ear stage casing, on fixed mounting, be fixed with the adjusting double-screw bolt, described adjusting double-screw bolt passes the adjusting mount pad to the right, and is bolted with adjusting nut in adjusting double-screw bolt right part.
Described train wheel bridge and lower plate all be one section circular-arc.Described elasticity roller is made by rubber.
The utility model can be realized easily and can turn to, and need not to leave insulating ladder when the constructor operates, and makes hot line job efficient improve greatly.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the utility model mainly is made of last terraced inner panel 1, last terraced outside plate 2, upper junction plate 3, descending stair inner panel 4, descending stair outside plate 5, lower connecting plate 6, first bearing pin 7, bracing frame 8, fixed mounting 9, adjusting nut 10, second bearing pin 11, adjusting double-screw bolt 12, adjusting mount pad 13, the 3rd bearing pin 14, train wheel bridge 15, lower plate 16, transition mount pad 17, elasticity roller 18 etc.
The electric pole construction insulating ladder that turns to of the present utility model, it comprises by last terraced inner panel 1, go up terraced outside plate 2 and be set up in terraced inner panel 1, go up the last ladder that the upper junction plate 3 between the terraced outside plate 2 constitutes, descending stair inner panel 4, descending stair outside plate 5 and be set up in descending stair inner panel 4, the following ladder that lower connecting plate 6 between the descending stair outside plate 5 constitutes, the last terraced inner panel 1 of last ladder, go up the descending stair inner panel 4 of terraced outside plate 2 left side sections and following ladder, but descending stair outside plate 5 left side sections are hinged to the support body of folding shape by first bearing pin 7, the last terraced inner panel 1 of last ladder, go up the soffit and following ladder descending stair inner panel 4 in terraced outside plate 1 stage casing, be provided with bracing frame 8 between the upper surface in descending stair outside plate 5 stage casings, right part at last terraced outside plate 2 and descending stair outside plate 5 is equipped with fixed mounting 9, the right part of going up terraced inner panel 1 and descending stair inner panel 4 is equipped with regulates mount pad 13, fixed mounting 9 is hinged with the head end of chain anchor ear by second bearing pin 11, the end of chain anchor ear is hinged with by second bearing pin 11 and regulates mount pad 13, described chain anchor ear by some the 3rd bearing pins 14 with some train wheel bridges 15, lower plate 16 hinged forming, be rotatably connected to elasticity roller 18 on the 3rd bearing pin 14 between train wheel bridge 15 and the lower plate 16, be in being hinged on the transition mount pad 17 of the 3rd bearing pin 14 in chain anchor ear stage casing, on fixed mounting 9, be fixed with and regulate double-screw bolt 12, described adjusting double-screw bolt 12 passes to the right regulates mount pad 13, and is bolted with adjusting nut 10 in adjusting double-screw bolt 12 right parts.
Described train wheel bridge 15 and lower plate 16 all be one section circular-arc.Described elasticity roller 18 is made by rubber.
During use, earlier adjusting nut 10 is screwed out to the right, make and regulate mount pad 13 disengaging adjusting double-screw bolts 12, make adjusting mount pad 13 1 ends of chain anchor ear become free end, find the electric pole that needs construction, again the chain anchor ear is embraced electric pole, will regulate jack sleeve on the mount pad 13 outside regulating double-screw bolt 12, tighten adjusting nut 10 and screw left, plurality of elastic roller 18 promptly tightly is trapped among the electric pole outer wall at this moment.
Owing to adopt column type elasticity roller 18 to contact in the utility model with electric pole, thereby reach the purpose fastening with electric pole, hot line job such as needs displacement or when turning to, only needing personnel to stand in the direction that shifts to needs on the insulated platform firmly pedals, the just rotatable a bit of distance of insulating ladder of the present utility model is pedaled again again and is moved.So, the constructor stands on the insulating ladder just can have enough working ranges, once just can finish the livewire work of three-phase conducting wire, has improved the livewire work effect greatly.And the chain anchor ear in the utility model can adapt to the electric pole construction use of various diameters.
