Abstract
The utility model discloses a dedicated flexible ladder used for replacing insulators. The flexible ladder comprises a plurality of ladder pillar units; a fastener is arranged on the ladder pillar at the top of each ladder pillar unit; a hook is arranged on the ladder pillar at the bottom of the ladder pillar unit; the ladder pillar unit comprises the two ladder pillars and a foot board; a ring is arranged at one end of each ladder pillar, and a hasp is arranged at the other end thereof; hasps are arranged at both ends of the foot board; both ends of the foot board are connected with the rings of the ladder pillars through the hasps respectively; and the ladder pillars are connected with each other through the rings and the hasps. The utility model has the advantages that the structure is simple; the connection among the rings and the hasps is convenient; the installation is fast; the use is convenient, safe and reliable; the work intensity of overhaul personnel and operating personnel is reduced; the safety factor during operation is enhanced; only one person is required during operation; and the labor efficiency is improved.
Description
Technical field
The utility model relates to a kind of rope ladder, is specifically related to a kind of special-purpose rope ladder of changing insulator.
Background technology
Along with the quickening of power grid construction, in order to improve the safe and reliable of electrical network, reduce the time of repair apparatus in recent years, transmission line of electricity has been used a large amount of composite insulators.At present, domestic when the maintenance circuit, traditional method is that composite insulator carries out operation about adopting rope ladder, Chinese patent 200720158324.3 discloses a kind of rope ladder of being made up of tightrope and foot-operated pipe, but this rope ladder easily about in addition stir up and down, so very dangerous up and down when the maintainer works, rope ladder ascend operation security performance is relatively poor, working strength of workers big, inefficiency.The hard terraced operation of employing that also has, is used all very inconveniently at hard ladder carrying during operation, and labour intensity is big, inefficiency, security performance are relatively poor.
The utility model content
The technical problems to be solved in the utility model is to change the used rope ladder of composite insulator to stir easily, provides a kind of replacing insulator special-purpose rope ladder.
The technical solution of the utility model is: a kind of special-purpose rope ladder of changing insulator, comprise several cleat stanchion unit, the cleat stanchion at top, cleat stanchion unit is provided with fastener, the cleat stanchion of cleat stanchion unit bottom is provided with hook, described cleat stanchion unit is made up of two cleat stanchions and foot rest, cleat stanchion one end is provided with ring, and the other end is provided with hasp; The foot rest two ends all are provided with hasp; The foot rest two ends link to each other with the ring of cleat stanchion respectively by hasp, and cleat stanchion links to each other with hasp by ring with cleat stanchion.
Described fastener is provided with restraint zone, and the cleat stanchion at top, cleat stanchion unit is fixedlyed connected with restraint zone by insulating slab.
Described fastener is provided with flat mouthful of groove.
Described cleat stanchion and foot rest are with the anti-slip rubber cover.
The beneficial effects of the utility model are: the utility model is simple, and ring is easy to connect with hasp, installs fast, easy to use, safe and reliable.Alleviate the upkeep operation personnel labor intensity, strengthened the job safety coefficient, only needed one man operation, improved efficiency.
