Abstract
The utility model discloses a kind of insulated ladder tail fixing device, comprise crossbeam and be located at respectively two bearings at two ends, crossbeam bottom; Two ends, crossbeam top are respectively provided with a ladder snap ring, and the bottom of two bearings respectively offers a leg-of-mutton draw-in groove, two draw-in grooves be arranged in parallel and and crossbeam between there is angle.The utility model can well be fixed on insulated ladder on tower material of iron tower, compared with original use rope fixed form, has increased steadiness and fail safe, and easy to operate, increases work efficiency.
Description
Technical field
The utility model relates to a kind of high voltage transmission line live work instrument, is specifically related to a kind of insulated ladder tail fixing device.
Background technology
Insulated ladder is one of the most frequently used instrument of overhead transmission line upkeep operation, is often used for forming one " bridge " reliably between wire and steel tower, with convenient working.Therefore the soundness of this " bridge " is just particularly important, will ensure on the one hand the mechanical strength of insulated ladder, will ensure on the other hand the fixing reliable of it.
Way is in the past by rope, the afterbody of insulated ladder and tower material of iron tower to be fixed together; but due to the scalability of rope and the impact of binding method and human factor; it is fixing not firm usually can to cause, and causes insulated ladder to tilt, play rolling, and then affects the fail safe of work.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fixed, safe insulated ladder tail fixing device.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of insulated ladder tail fixing device, comprises crossbeam and is located at respectively two bearings at two ends bottom crossbeam; Two ends, crossbeam top are respectively provided with a ladder snap ring, and the bottom of two bearings respectively offers a leg-of-mutton draw-in groove, two draw-in grooves be arranged in parallel and and crossbeam between there is angle.
Wherein, the angle steel that described bearing is used by steel tower is made.
Wherein, on two outer surfaces of described bearing, be respectively hinged with a hook.
Wherein, the angle between described draw-in groove and crossbeam is 45-90 degree.
The beneficial effect that adopts technique scheme to produce is:
The utility model is fixing for insulated ladder afterbody, and crossbeam is irony or steel, and deck adopts angle steel to make, and therefore has enough mechanical strengths.The utility model can well be fixed on insulated ladder on tower material of iron tower, compared with original use rope fixed form, has increased steadiness and fail safe, and easy to operate, increases work efficiency.
The utility model uses flexibly, is convenient to mounting or dismounting, has greatly improved at work the fail safe in use insulated ladder process, prevents from occurring in operation process that flat ladder tilts, beats the phenomenons such as rolling even comes off, and avoids having an accident.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is application schematic diagram of the present utility model;
In figure: 1, crossbeam, 2, bearing, 3, bearing, 4, insulated ladder, 5, angle steel, 6, angle steel, 7, hook.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of insulated ladder tail fixing device, comprises crossbeam 1 and is located at respectively two bearings 2,3 at crossbeam 1 two ends, bottom; Crossbeam 1 two ends, top are respectively provided with a ladder snap ring, and the bottom of two bearings 2,3 respectively offers a leg-of-mutton draw-in groove, two draw-in grooves be arranged in parallel and and crossbeam 1 between there is angle, and angle between draw-in groove and crossbeam 1 is 45-90 degree; On two outer surfaces of bearing 2,3, be respectively hinged with a hook 7.Crossbeam 1 is irony or steel, and the angle steel that bearing 2,3 is used by steel tower is made, and the outer rib of angle steel is welded on the bottom of crossbeam 1, therefore, the utlity model has enough mechanical strengths, can on steel tower, firmly support insulated ladder.
As shown in Figure 2, the utility model by the afterbody of insulated ladder 4 be fixed on electric power pylon be decussation arrange two angle steel 5,6 on.Crossbeam 1 is positioned at the below of insulated ladder 4, and the ladder at its two ends, a top snap ring is fixed on the afterbody of 4 two thick bars of insulated ladder, fixed position in two thick bars of two ladder snap rings is also inconsistent, in figure, two ladder snap rings lay respectively at the both sides of first cross bar, and crossbeam 1 favours cross bar.The draw-in groove of two bearings 2,3 at crossbeam 1 two ends, bottom is stuck on the outer rib of two angle steel 5,6, and the hook 7 at bearing two ends hooks angle steel 5,6 from below.The angle steel that two bearings 2,3 all adopt steel tower to use is made, there is enough mechanical strengths, and because the active force of 2,3 pairs of two angle steel 5,6 of two bearings is contrary, two bearings 2,3 can firmly be stuck on the outer rib of two angle steel 5,6, can well support works personnel stand in operation on insulated ladder 4, ensure not occur that flat ladder tilts, beats the phenomenons such as rolling even comes off, avoid having an accident.
