Abstract
The utility model relates to a kind of portable fork beam cat ladder, forms primarily of terraced body, hook, draw-in groove, draw ring and loose-leaf.Ladder, as " order " font, has gemel connection between upper and lower two sections of terraced body, and respectively there is one group of draw-in groove the both sides of ladder hypomere with it; The tip flexion of hook, lower end and terraced body are fixedly linked; Draw ring has multiple, is fixed on terraced body both sides mutually stragglyly.During use: staff climbs anchor ear place to fork beam with climbers, then take over the fork beam cat ladder of ground cooperation personnel transmission and launched, with hook, draw-in groove, cat ladder being fixed on fork beam, subsequently just fit well step body crosspiece operation on fork beam.The fork beam climbing ladder apparatus of the utility model has high safety.Structure is simple, and simple operation, increases work efficiency, and the advantage such as reduce labor intensity, and this fork beam cat ladder time used shortens about 90% than traditional work.
Description
Technical field
The utility model relates to a kind of climbing tool, the climbing device of specifically concrete rod fork beam maintenance.
Background technology
Transmission line of electricity is after operation a period of time, and the fork beam position of concrete bar there will be the defect phenomenons such as yoke plate corrosion, nut disappearance, end corrosion.To this, the method that operating personnel adopts climbers to climb fork beam (fork beam is square) usually carries out defect elimination.Described climbers, its shape is semi arch, and for climbing concrete bar, in use, often there will be the phenomenons such as skidding or bite, the safety of operating personnel in serious threat to these climbers; And due to operating personnel's longevity of service, timid in the heart, foot is unstable, affects operation process, inefficiency.
Utility model content
The purpose of this utility model is: provide that a kind of structure is simple, safe and reliable, simple operation, reduction labour intensity, the fork beam climbing ladder apparatus of increasing work efficiency.
The fork beam climbing ladder apparatus of the utility model, is formed primarily of terraced body 1, hook 2, draw-in groove 3, draw ring 4 and loose-leaf.
Described terraced body 1 is " order " font.Ladder body has upper and lower two sections, therebetween by gemel connection; , respectively there is one group of draw-in groove 3 both sides of ladder upper and lower section of body 1.
Described hook 2, its tip flexion, lower end and terraced body 1 are fixedly linked.Terraced body 1 can be hung on fork beam end by this hook 2, in case cat ladder glides.
Described draw ring 4, has multiple, and stagger respectively and be fixed on terraced body 1 both sides, when facilitating personnel upper and lower, hand is grabbed, and ensures the personal safety in climbing process.
During use, staff climbs anchor ear place to fork beam with climbers, take over ground coordinate the fork beam cat ladder that passes over of personnel and cat ladder is launched, with hook, draw-in groove, cat ladder is fixed on fork beam, check undoubtedly, foot tramples terraced body crosspiece and climbs to fork beam operating location along cat ladder, carries out defect expressivity work.After operation completes, cat ladder is regained and returns to ground.The fork beam climbing ladder apparatus of the utility model is collapsible, has high safety.Structure is simple, and simple operation, increases work efficiency, and the advantage such as reduce labor intensity.Compared with conventional method, this fork beam cat ladder time used shortens about 90% than traditional work.
Accompanying drawing explanation
Fig. 1. the front view of the utility model embodiment shape and structure;
Fig. 2. the lateral view of the present embodiment shape and structure.
In figure, 1 is terraced body, 2 are hooks, 3 are draw-in grooves, 4 is draw rings.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment, a kind of portable fork beam cat ladder
This fork beam cat ladder is formed primarily of terraced body 1, hook 2, draw-in groove 3, draw ring 4 and loose-leaf.
Ladder body 1 is " order " font.Ladder body has upper and lower two sections, therebetween by gemel connection; Respectively there is one group of draw-in groove 3 both sides of ladder hypomere with it.
Described draw-in groove 3, adopts two outstanding square steel and terraced body to be welded.Two square steel level intervals are slightly wider 1 centimetre than the width of fork beam, terraced body firmly can be stuck on fork beam, prevent its double swerve.
Ladder body 1 is fixedly laid on fork beam surface by draw-in groove 3, rides on it when staff is upper and lower.10*10 square steel is adopted to be welded.
Hook 2, its upper-end bent, lower end and terraced body are fixedly linked.By this hook, cat ladder is suspended to fork beam end, in case cat ladder glides.∮ 12 round steel is adopted to process.
Described draw ring 4, has four, and it staggers respectively and is welded on the both sides of terraced body 1 upper-lower section, facilitates personnel upper and lower, ensures the personal safety in climbing process.Adopt ∮ 8 round steel material.
This embodiment use time, first cat ladder is carried into fork beam under anchor ear place, utilize hook 2 and draw-in groove 3 cat ladder is fixed on fork beam on, staff can complete defect expressivity work by cat ladder.
