Abstract
The invention provides an operation stand for exchanging insulators, which is suitable for a multi-voltage-class power transmission line of an electric power system. The operation stand consists of a stretcher bar capable of being hung on steel caps among ceramic bottles of the insulators, a steel cap hook is arranged at one end of the stretcher rod, and a seat plate and a pedal are arranged at the other end of the stretcher. The operation stand disclosed by the invention has a simple structure and is simply and firmly fixed on an insulator chain in hooking and hanging manner by fully utilizing a mechanical principle of a tamper frame and depending on a structure with double-chain insulators arranged in parallel, thus an operation posture of an operator on the insulator chain is well changed. After the operation stand disclosed by the invention is utilized, a person can operate on the insulator chain in a labor-saving and comfortable manner, so that the stability of the body of the person and the safety are improved.
Description
Technical field
The present invention relates to a kind of replacing insulator and use operating platform frame.
Background technology
In September, 2010, the building up of peaceful east-Shandong ± 660kV super high voltage direct current electricity transmission line, created on present China and even the world's direct current construction history three big: sectional area of wire is maximum, insulator sheet number at most, wire spacing is the wideest.Though the development work of check man's utensil draws to an end at present, repair method and scheme are still waiting further perfect.Particularly change strain insulator monolithic insulator work;, monolithic insulator heavier etc. big because of its insulator string spacing causes work difficulty to strengthen; Usually ride to sit on the insulator string operating personnel on the 500kV circuit and get final product work, still ± the 660kV DC line on just dying.Insulator disk track 380mm, apart from 650mm, the operating personnel can't sit at all in the above between string.When getting into lead through insulator, can only adopt and creep or the method for " striding two short three " is carried out, operating personnel's health stable very poor, rising does not sell at all carries out other operation.Because the insulator tonnage is big, weight is also just big, the jig that changes monolithic is also heavy especially, just can carry out this work so the operating personnel only possesses the good working posture, wastes time and energy.
Summary of the invention
Technical problem to be solved by this invention provides a kind of electric power system multi-voltage grade transmission line that is applicable to easy to use and good stability and changes insulator and use operating platform frame.
The present invention adopts following technical scheme:
The present invention can be hung on by one that the stretcher rod on the steel cap constitutes between the porcelain insulator bottle, and an end of described stretcher rod is provided with steel cap hook, and the other end of stretcher rod is provided with seat board and pedal.
Good effect of the present invention is following:
Simple structure of the present invention; Make full use of and ram the principle that booster is learned; The structure that relies on two insulator strings to be arranged in parallel adopts not only simple but also firm the present invention is fixed on the insulator string of hook, extension mode, thereby has well changed the work posture of operating personnel on insulator string.The operating platform frame of making of the present invention according to GB GB/T18037-2000 " high-altitude operations tool specification requirement and design guide rule ", through mechanical test, satisfies the work high above the ground specification requirement.Operating platform frame of the present invention is long to be 1.2m, and wide is 0.3m, and weight is 5.8kg, and the maximum capacity load is 350 kg, can satisfy the load of an operation personnel own wt fully.
After using operating platform frame of the present invention, can't on insulator string, operation be improved to laborsaving comfortable operation from personnel, further strengthen the stability of personnel's healths, safety system is improved.Through overtesting, operating platform frame of the present invention adorns on strain insulator, tear open conveniently, and the operating personnel is free and relaxed during transferring position between insulator and paralell; When on paralell of the present invention, operating; Good stability is convenient to operation, has guaranteed operating personnel's personal safety.In addition, job platform frame of the present invention can also be applied to the setting of personnel's inconvenience erect-position on the iron tower, and purposes very extensively.
Operating platform frame of the present invention is novel in design, and advantages of small volume is beneficial to vehicle transport.The present invention adopts high strength linepipe, and weight is light, transmit on the tower when not only being convenient to work high above the ground, and when working truck can not arrive on high mountain, personnel carries convenient.Install simply, save the work high above the ground time, alleviate operating personnel's labour intensity.Seat board height 450mm of the present invention is equal to routine office work seat height, comfort for sitting posture, and be provided with foot pedal, personnel can stand up in operating process, are convenient to the operation of different angles.Anti-skidding backrest has avoided personnel when overexerting, and health is slippage backward.
At present, the UHV transmission line of China is in the starting stage, electric pressure improve constantly the main feature that becomes power grid construction with emerging in an endless stream of new equipment, new material.Large-tonnage application of insulator in the DC line forces us must constantly improve the upkeep operation methods.The present invention change insulator with the successful solution of the birth of operating platform frame this electric pressure transmission line can't operation on insulator string a difficult problem.Even how the wire pitch of circuit is adjusted in the future, we still can utilize the design principle of paralell of the present invention, and the manufacturing dimension of adjustment crosshead is made corresponding " operating platform frame ".Thus, paralell of the present invention is widely used, and has higher promotional value.
Operating platform frame of the present invention is simple in structure, and materials are few, and low cost of manufacture is economical and practical.Adopt the present invention to make the operation that can't carry out be able to smooth completion, zero low resistance insulator of discovery in service can in time be changed, sound assurance the stable operation of electrical network, the tremendous economic of having avoided causing owing to equipment fault is lost.The cleaning of rope is transmitted in insulation, guarantees to have practiced thrift under the safe prerequisite fund that rope is transmitted in insulation of buying.
