Abstract
The invention relates to an improved double fission rope ladder hanging head which comprises a ladder frame, a rotating head, movable joints for controlling the rotation of the rotating head, and a locking device. The ladder frame consists of two steel tubes, the bottoms, the middle parts and the upper parts of the two steel tubes are respectively connected with a bottom rod, a cross bar and a bent tube, and the upper ends of the two steel tubes are both provided with the movable joint; each movable joint comprises a shell and a rotating core, the bottom end of each shell is fixedly connected with the upper end of the corresponding steel tube of the ladder frame, the bottom part of each rotating head is inserted in the corresponding shell and fixedly connected with the corresponding rotating core; the upper part of each rotating heat is bent inwards to form a semi-circle shaped bend, a rotating shaft is arranged between the two semi-circle shaped bends and provided with rollers, and a block and a blocking dog, as well as a bolt, are respectively arranged at the opposite ends of the two rotating heads. In the invention, the rotating heads can overturn outwards and inwards and can ensure that a rope ladder can be hung quickly and firmly; and because of adopting an inward overturning and external hanging mode, the rope ladder can work stably and continuously without the blockage of a spacer rod in advancing process, thereby reducing the height danger coefficient of workers.
Description
Technical field
Instrument is climbed in the maintenance used when the present invention relates to a kind of 220kv high pressure two division circuit on-line treatment, particularly relates to a kind of two fission rope ladder hanging head.
Background technology
Power department is pass by the middle of two strand roads at the terraced head of the rope ladder used during two division circuit on-line treatment 220kv high pressure now, more outwards bends, and hang on the line, this kind of mode is interior suspension type.For ensureing the high-level stability of circuit, two strand roads are just provided with spacer rod at a certain distance, use aforementioned rope ladder when line maintenance, owing to adopting interior suspension type, cause when running into spacer rod, operating personnel can only first straddle on the line, then rope ladder is moved past spacer rod, personnel are again down on rope ladder subsequently, continue to move ahead.High-altitude circuit swings with the wind itself, when the personnel of adding straddle on the line, once crank, is easy to falling from high altitude accident occurs.Meanwhile, the terraced head of this kind of rope ladder needs to climb to rope ladder top just can locking, and in climbing, if rope ladder shaking amplitude is excessive, terraced head is easy to depart from circuit, easily security incident occurs.
Summary of the invention
The object of the invention is to propose a kind of without the need to moved by hand rope ladder, can on the circuit of high-altitude continuously, free of discontinuities advances, ensure to hang simultaneously, climb, the improved double fission rope ladder hanging head of job safety.
The object of the present invention is achieved like this: improved double fission rope ladder hanging head, is by ladder, is installed in ladder upper end, rotating rotary head, controls the turning joint that rotary head is rotated, and locking device composition.Ladder is made up of two vertical and parallel steel pipes, and the bottom between two steel pipes, middle part and top are connected to bottom bar, cross bar and bend pipe, have rope ladder suppending hole at bottom bar two ends.All turning joint is equiped with in the upper end of aforementioned two steel pipes.Turning joint comprises shell and turn core, and shell bottom is fixedly connected with aforementioned ladder steel pipe upper end, inserts in shell bottom rotary head, and with turn core and be fixedly connected with.Its top of rotary head bends inwards, and forms semicircle elbow, between semicircle elbow, be equiped with rotating shaft, and in rotating shaft, cover has roller, and two rotary head opposite end places are equiped with lock body and dead bolt respectively, and are have latch, and lock body, dead bolt and latch form locking device.
Terraced head of the present invention can outwards, inwardly overturn, suspension rope ladder that can be quick, safe.After rope ladder hangs, the locking device of rope ladder head can control unlatching, elementary locking, safety when support personnel climbs on ground.Owing to adopting varus, outer suspension type, therefore rope ladder can not by the obstruction of spacer rod in traveling process, can steady, unremitting operation, reduces personal height danger coefficient.The present invention is applicable in all conveyings electricity specialty, telecom communication industry, the elimination of defect that multiple fission conductor does not have a power failure.Thoroughly solving must have a power failure in the past could carry out defect expressivity to multiple fission conductor, but the major defect cannot eliminated in charged situation.Effectively prevent the major accident causing broken string because of applying for having a power failure, effectively ensure the safe operation of overhead transmission line, ensure that completing smoothly of the every safety index of electric power enterprise, firmly stop the transmission line of electricity trip accident caused because of maintenance responsibility.Enable industrial, civilian, enjoy reliable power supply other all kinds of power consumer continued smooth.
