Abstract

The utility model provides an insulating flat ladder tail end fixer, is including being used for with two ladder head fixtures of insulating flat ladder tail end fixed, the iron tower fixer of being connected with ladder head fixture, two ladder head fixtures fix on a flat ladder hangs epaxially, the iron tower fixer be double hook fixer. The hook is composed of a hook sleeve sleeved on the hanging shaft of the horizontal ladder and a hook fixed on the hook sleeve, the hook is composed of an upright post and an inclined hook on the upper portion, and an included angle r between the inclined hook and the upright post is 135 degrees. The utility model has the advantages that: because the steel pylons in China are made of angle steel and are mostly in a cross shape, square hooks with 135-degree oblique angles can be just matched with the tower, the ladder head clamps on two sides are connected into a whole through a flat ladder hanging shaft, and the ladder can be stably erected. The iron tower fixer is provided with the double-hook device, so that the device is very simple to mount and dismount, is convenient to carry, is very stable to mount on the iron tower after the two hooks are reversely arranged, and cannot be unhooked. The hook sleeve is guaranteed not to displace when in use through the limiting nut, and the safety and the durability of equipment are improved.

Description

Insulated ladder tail end fixture

Technical field

The utility model relates to a kind of high voltage transmission line live work instrument, particularly a kind of insulated ladder tail end fixture.

Background technology

When hot line maintenance enters highfield, " flat terraced method " is the higher method of utilization rate, need flat ladder also fixing between wire and steel tower during operation, flat ladder bundlees with rope usually in steel tower one side, such fixing means is not only wasted time and energy, tie up the situations such as not firm, becoming flexible just might appear in flat ladder, inclination are slightly arranged, work high above the ground personnel's safety is constituted a threat to.The disclosed a kind of Antiskid insulated flat ladder of Chinese patent CN201137455Y, although used Universal joint and on it design of draw-in groove ladder can be fixed on the angle bar of steel tower, but the fixed form stability fastening with draw-in groove is not enough, rotating shaft on the Universal joint has reduced the stability of ladder, and load-bearing is very large in the practical operation of " flat terraced method ", very easily cause damage, increased use cost, bring potential safety hazard to construction operation.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of insulated ladder tail end fixture.

The technical solution adopted in the utility model is: a kind of insulated ladder tail end fixture, comprise for fixing two the ladder jigs of insulated ladder tail end, the steel tower fixture that is connected with a ladder jig, it is characterized in that described two ladder jigs are fixed on the flat terraced suspended axle, described steel tower fixture is the double hook fixture.

Described insulated ladder tail end fixture is characterized in that what described double hook fixture was comprised of two steel towers hook in the inboard that is arranged at respectively two ladder jigs or the outside.

Described insulated ladder tail end fixture, it is characterized in that described steel tower hook is by being socketed in the hook sleeve pipe on the flat terraced suspended axle and being fixed on that hook on the hook sleeve pipe consists of, described hook is comprised of the oblique hook on column and top, and the angle r between between described oblique hook and column is 135 °.

Described insulated ladder tail end fixture is characterized in that described two hooks oppositely arrange, and described hook sleeve pipe inboard is provided with stop nut.

The beneficial effects of the utility model are: because the electric power pylon material therefor of China is angle steel, and shape mostly is " ten " word chiasma type, therefore the square hook at 135 ° of oblique angles just in time can mate with pylon, a both sides ladder jig is connected as a single entity by a flat terraced suspended axle, can makes firm the setting up of ladder.The steel tower fixture is adopted the double hook device, so that equipment is installed with dismounting is all very simple, be easy to carry, after particularly two hooks oppositely being arranged, be installed on the steel tower very firmly, can not produce the unhook phenomenon.Guarantee that by stop nut the hook sleeve pipe does not produce displacement in use, has increased fail safe and the durability degree of equipment.

Among the figure, 1-steel tower hook, 2-puts down terraced suspended axle, a 3-ladder jig, 4-puts down terraced longeron, 5-jig bolt, 6-puts down terraced crossbeam, and 7-links up with sleeve pipe, 8-hook, 9-column, the oblique hook of 10-, 11-stop nut, 12-steel tower.

Embodiment

Shown in Figure 1, insulated ladder tail end fixture of the present utility model comprises two ladder jigs 3 that are fixed on flat terraced longeron 4 tail ends, the top of these two ladder jigs is fixed on the two ends of putting down terraced suspended axle 2 by nut, and the inboard of two jigs or the outside are respectively arranged with steel tower hook 1 on flat terraced suspended axle.There is jig bolt 5 lower end of a ladder jig.Also has flat terraced crossbeam 6 among the figure.

Shown in Fig. 2-3, steel tower hook 1 is linked up with sleeve pipe 7 and is fixed on the hook 8 of linking up with on the sleeve pipe 7 by the bottom and consists of.Wherein link up with 8 and be comprised of two parts, the bottom is the column 9 fixing with hook sleeve pipe 7, is oblique hook 10 on column 9 tops, and angle is 135 degree between described oblique hook 10 and column, and its wrap direction is the outside axial line of flat terraced suspended axle 2.Two hooks are socketed on the flat terraced suspended axle by sleeve pipe 7, also have stop nut 11 in a side of sleeve pipe.Two hook setting parties on flat terraced suspended axle spend to being mutually 180.

Shown in Figure 4 is a use state of the present utility model, when the close 12 liang of angle bar crosspoints of steel tower of flat terraced hanging position, can select two hooks are arranged at a ladder jig inboard.Inboard fixing with stop nut 11 at sleeve pipe.
