Abstract
The invention relates to a suspension device applied to overhead operation of electricity workers, and in particular relates to an insulating horizontal ladder suspension device for an electric power tower. The device comprises a shaft; the two ends of the shaft are respectively sheathed with a shaft sleeve capable of rotating around the shaft; a connecting rod is fixed on each shaft sleeve; the top of each connecting rod is bended to be in a hook shape and is used for hanging; the two ends of the shaft extends outwards; the extension parts of the shaft are respectively and fixedly provided with a ring-shaped connecting piece. Therefore, the hook-shaped tops of the connecting rods can be hung on a triangular support frame of the line iron tower, and the ring-shaped connecting pieces are fixedly connected with two ladder beams of a ladder, so that a worker can sit on the ladder to construct and overhaul the power tower, can conveniently work and is unlikely to have work fatigue.
Description
Technical field
The suspension arrangement of using when the present invention relates to a kind of work about electric power personal height operation, particularly a kind of electric force pole tower insulated ladder suspension arrangement.
Background technology
Transmission line of electricity accounts for important position in power system, the transmission line of electricity workman mainly is engaged in work such as power transmission sequence construction, operation and repair and maintenance, in these work, has and much finishes at line steel tower, the height of line steel tower more than 18 meters, belongs to work high above the ground substantially.
The staff is in line steel tower work at present; all be to protect by protectors such as safety belts; self stand or rest on and construct on the line steel tower or overhaul; because the trackman works long hours on the iron tower of being everlasting; the work of so long dependence iron tower is operated not only bad for the workman; and be easy to generate work fatigue, thereby security incident takes place.
Summary of the invention
A kind of electric force pole tower insulated ladder suspension arrangement of the present invention has overcome the defective of prior art, and a kind of a kind of electric force pole tower insulated ladder suspension arrangement of using when the long working of high-altitude is provided.
A kind of electric force pole tower insulated ladder suspension arrangement of the present invention, comprise axle, the two ends of described axle all are set with can be along the axle sleeve of axle rotation, connecting rod is fixedly arranged on the described axle sleeve, the top of described connecting rod is bent into hook-shaped and is used for hanging, the two ends of described axle stretch out, on the extended axle circular connector is arranged fixedly respectively, like this, the top-hung of connecting rod is hooked on the triangle support frame of line steel tower, two terraced beams of circular connector and ladder are connected and fixed, and the staff just can be sitting in and construct on the ladder and overhaul, and also more conveniently also are not easy to occur work fatigue thereby the staff is worked together.
Described axle comprises integrated first horizontal axis, vertical axis and second horizontal axis, described first horizontal axis and second horizontal axis are fixed by vertical axis, described first horizontal axis and second horizontal axis are done up and down with respect to the vertical axis center and are rotatablely moved, described axle sleeve is set on first horizontal axis and second horizontal axis, like this, because first horizontal axis and second horizontal axis are done up and down with respect to the vertical axis center and are rotatablely moved, just can adapt to different triangle support frames by the position of adjusting first horizontal axis and second horizontal axis, effectively avoid because the triangle support frame of different line steel tower all the ladder that causes inequality is not steady, make the ladder place at grade.
The outside of described axle, axle sleeve, connecting rod, circular connector all is coated with insulated hull, and insulated hull is used for preventing that phenomenons such as electric leakage, static from taking place.
The advantage that has with prior art is: use a kind of electric force pole tower of the present invention insulated ladder suspension arrangement, the staff can directly be sitting in the enterprising line operate of ladder, need not directly rest on the iron tower again, be not easy to produce tired, avoid producing security incident, this clearly demarcated also can be in the enterprising enforcement usefulness of different line steel towers, simple to operate, can improve work efficiency of workers, also can reduce the generation of security incident.
