The invention discloses a single tower crane for replacing disconnecting links. The single tower crane aims to solve the problem that a tower crane used in the existing operation transformer substation disconnecting link replacing method has defects in the prior art. The single tower crane for replacing the disconnecting links comprises an upper stand column, a lower stand column, a lifting head and a fixing seat, the upper stand column and the lower stand column are detachably connected, the lifting head is arranged at the top end of the upper stand column, the fixing seat is arranged at the bottom end of the lower stand column, and a lifting lug is arranged on the lifting head. The single tower crane has the advantages that a construction method is simple and saves labor and time, and the tower crane is small in size, low in weight, and convenient to transport, carry, assemble and disassemble; the tower crane is convenient to transport, carry and assemble in an operation transformer substation, and the tower crane can be assembled, disassembled and lengthened and is high in operability; the safety coefficient is no less than 2.5 times that of the prior art and is controllable, and safety of construction staff and safety of operation devices are controllable.
Description
Technical field
The present invention relates to a kind ofly for changing the single pole of disconnecting link, relate in particular to a kind ofly for changing or the single pole of new clothes 220KV, 110KV disconnecting link, belong to lifting lifting class tool configuration.
Background technology
Former operation transformer station changes disconnecting link construction method, 220kV, 110kV disconnecting link group, 10 centimeters of common steel tube poles of the new Ф of employing more change the outfit, long 6.5 meters, can not segmentation, oversize vehicle transportation, enter operation transformer station and winch to 2 layers of platform, adopt lifting process, determine that clearance space meets the lift-off of safe distance pole, 12 people are compounding practice simultaneously, unified command, 3 people are surely to pole root, 4 people control wind rope direction, with extremely vertical 90 ° of artificial acts, and pole is moved to disconnecting link spend the colligation of blue frame root, wind rope is fixed, unified cooperation, assume unified command of 1 people, transportation assembling 4 people, ascend operation 2 people, 4 people are drawn in lifting, 1 group of replacing of disconnecting link is complete, use the same method and move to 2 groups of disconnecting link places, carrying out lifting prepares.
Shortcoming:
1, oneself making, iron steel tube holding pole, without reliable coefficient of safety, lifting loads is without test, and risk hidden danger is larger.2, whole 6.5 meters of poles, transportation length are carried inconvenience, must transport with oversize vehicle.3,6.5 meters of steel tube holding poles are at large, the upper and lower limited space of operation transformer station radius of turn, and the security risk that operation exists to equipment is larger.4, drop into construction operation personnel 12 people, personnel labor intensity is large, very easily damages disconnecting link porcelain vase, and construction method is loaded down with trivial details.5, efficiency of construction is low, and work progress difficulty is many, and personal safety, device security risk factors are more, and safe practice economic index is difficult to control.
Summary of the invention
Technical problem to be solved by this invention is: change for existing environment Central Plains operation transformer station the pole adopting in disconnecting link construction method and have the shortcoming in background technology.
The object of this invention is to provide a kind of for changing the single pole of disconnecting link.
The present invention is as follows for solving the problems of the technologies described above adopted technical scheme:
For changing a single pole for disconnecting link, comprise upper pillar stand, lower pillar stand, suspention head and holder; Between described upper pillar stand and lower pillar stand, be detachable connected mode, suspention head is arranged on the top of upper pillar stand, and holder is arranged on the bottom of lower pillar stand; Described suspention head is provided with hanger.
Upper pillar stand described in the present invention, lower pillar stand all adopt aluminum alloy materials of the prior art to make.
The top of suspention head of the present invention is provided with the cable loop that is no less than two; Described cable loop is symmetrical arranged.The object that the present invention arranges cable loop on the top of suspention head is, makes fixing more firm of pole of the present invention.
Upper pillar stand of the present invention and lower pillar stand are expansion link.Upper pillar stand of the present invention and lower pillar stand adopt expansion link be for can better be applicable to differing heights with changing, expand its range of application and recycling rate of waterused, be convenient to be convenient for carrying simultaneously, reduce working space, the scope of application is larger.
Holder of the present invention is arranged on lower pillar stand bottom, and holder both sides earrings adopts U-shaped ring to be reliably connected with equipment supporter root, to fix.
Adopt pole of the present invention, change 220kV disconnecting link group process:
In Reconstruction Project engineering construction, change especially the work of disconnecting link in operation transformer substrate two-layer platform interval, power failure, interval, adjacent both sides, in operation, is changed 220kV disconnecting link construction operation, is adopted single combination, new aluminum alloy tubular type pole.0.5 centimeter of pole wall thickness, 8 centimeters of pole diameters, point two joints are to dress, and 2.5 meters, every joint, separately adds 0.5 meter of base, 0.5 meter, top cap, 6 meters of total lengths, 20 kilograms of pole total weights.Work progress 1 people commander, 2 people's work high above the ground, 4 people transport assembling, and transportation porcelain vase assembling, be bolted on holder on two-layer platform, adopts after reeving cable loop and be fixed on two-layer platform, adopts chain block lifting.
The present invention's advantage compared with prior art: 1, construction method is easy, saves artificial, time, and pole volume is little, lightweight, and it is convenient that mounting or dismounting are carried in transportation.2, in operation transformer station carrying, to carry assembling convenient, dismounting lengthening, strong operability.3, coefficient of safety >=2.5 are times controlled, and the safety to workmen, the safety of operational outfit is controlled, can control.4, under the specific environment of operation transformer station, the feature of site layout project bonding apparatus structure can be controlled in the situation that narrow space is limited, guarantees personal safety, and the protection of equipment has been played safely to reliable controlled, energy control effect.
