Abstract

The utility model discloses a composite insulator replacing special rope ladder which comprises a ladder rope (1) and a foot tube (2). The foot tube is fixed between the ladder ropes (1) and is arranged evenly. A hanger (3) is fixed at the connection position at the lower end of the ladder rope (1). The upper end of the ladder rope (1) is fixed and connected with the lower end of a tightening belt (4) through an insulating board (9). The upper end of the tightening belt (4) is wrapped on a tightener (6) which is provided with a thread off prevention jack (5). A flat mouth groove (8) which is provided with a bolt (7) is arranged on the top of the tightener (6). A regulating hanger (10) is fixed at two ends of one foot tube (2) in the middle area. The rope ladder has high intensity, good insulation performance, light weight, folding function, high operation efficiency, security and reliability.

Description

Change the special-purpose rope ladder of composite insulator
Technical field
The utility model relates to a kind of employed ladder of the composite insulation period of the day from 11 p.m. to 1 a.m of changing in supply line.
Background technology
The composite insulation period of the day from 11 p.m. to 1 a.m is changed in line outage in the past, and the staff climbs on the shaft tower, after Chain block, back-up protection rope are in place, ladder is suspended on the cross-arm, and the operating personnel is along working to lead under the ladder.The ladder that uses in the work is an aluminum alloy material, collapsible pin nail formula, in light weight, carry more conveniently, but pin nail easily scratches the composite insulator full skirt, the ladder lower end can't be fixed, ladder is very dangerous up and down for personnel, and result of use is general, again because of insulator specifications and models difference, ladder length can not be regulated, and versatility is not strong.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of replacing composite insulator special-purpose rope ladder, and its technical scheme of taking is:
This rope ladder comprises the ladder rope and is fixed between the ladder rope and evenly distributed foot-operated pipe, the junction, lower end of ladder rope is fixed with hook, fixedly connected by insulating slab with the lower end of restraint zone in the upper end of ladder rope, the upper end of restraint zone is wrapped in and has on the very heavy fastener of anticreep, the flat mouthful of groove that has bolt established at the top of turnbuckle, and foot-operated pipe two ends in centre position are fixed with regulates hook.
The hook inboard can be provided with the anti-slip rubber pad, and foot-operated pipe two ends are socketed with the vulcanie cover.
By turnbuckle the length of restraint zone is regulated, can make rope ladder adjust to employed length, and regulate the length that hook also can be regulated rope ladder,, improve versatility to be used to change each model insulator.
Use special-purpose rope ladder time saving and energy saving, change composite insulator at every turn and only need 1 operating personnel, average every phase operating time is 13 minutes, every operation 7 minutes of shortening mutually, and the corresponding power off time that shortened has increased delivery, has alleviated intensity of workers.This rope ladder intensity height, good insulation preformance, in light weight, collapsible, carry light, the operating efficiency height, safe and reliable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in the figure, this rope ladder be about two sections, fix a plurality of evenly distributed foot-operated pipes 2 between them, ladder rope 1 is selected for use and is adopted insulation silk rope material, that this material has is in light weight, easy and simple to handle, long service life, be difficult for aging characteristics, can be widely applicable for each model insulator and more change jobs, can prevent induced electricity simultaneously, guarantee staff's safety.Foot-operated pipe 2 is selected pulling epoxy glass fiber silk stringing for use, and it is through on the rope ladder rope can wear-resistantly more increase its intensity, prevents that the staff from stepping on sky, slippage, is convenient to about the personnel.Foot-operated pipe 2 two ends socket rubber-like vulcanie covers, tube wall cuts wearing and tearing wound insulation rope for a long time in preventing to use.
For increasing the ladder tightness, junction, the lower end fixed hook 3 of two sections ladder ropes 1 is linked up with 3 built-in anti-slip rubber pads; during making; restrict the collar on 1 end of ladder is penetrated in the hook 3 and welds fixation, the inboard protection pad of placing of the collar, the collar on the protection ladder rope 1.Fixedly connected by insulating slab 9 with the lower end of restraint zone 4 in the upper end of ladder rope 1, restraint zone 4 is an insulation safety band pattern, and lower end is fixed on the insulating slab 9 that thickness is 1cm, is connected with two sections ladder ropes 1 with safety door hook, is convenient to dismounting.Be positioned at one of them foot-operated pipe two ends secured adjusted hook 10 in centre position, be convenient to connect, adjustable length can be used for changing each model insulator, improves versatility.
Turnbuckle 6 is selected high-strength tool steel material for use, and it is very heavy 5 to have anticreep, and the flat mouthful of groove 8 that has bolt 7 established at the top of fastener 6.Restraint zone 4 upper ends fixedly are wrapped on the turnbuckle 6, and when turnbuckle 6 tightened up restraint zone 4, anticreep very heavy 5 pinned restraint zone 4, prevents that it from being come out by gravity traction, thereby the length of whole rope ladder is remained unchanged, and guarantee that rope ladder is fixed, and prevents unexpected generation.
Change the composite insulation period of the day from 11 p.m. to 1 a.m when using this rope ladder, flat mouthful of groove 8 is stuck on the cross-arm, and it is fixing stable them by adjusting bolt 7, and tighten up or loosen restraint zone 4 by turnbuckle 6, adjust the length of rope ladder, so that make the hook 3 of rope ladder lower end hook lead, make whole rope ladder more fastening, be convenient to staff's rope ladder up and down.This rope ladder length is 2350mm, and adjustable-length is 960mm, and proximal length is 1100mm.
