Description

Change insulator and use instrument
Technical field
The utility model relates to the maintenance and the maintenance technology field of power equipment, particularly relates to a kind of replacing insulator and uses instrument.
Background technology
Insulator is a kind of special insulation control, is installed between the conductor of different potentials or between conductor and the current potential member, withstand voltage and mechanical stress effect, in overhead transmission line, plays an important role.
In overhead transmission line, insulator is between shaft tower and lead, and insulator has two basic effects, promptly support wire with prevent that electric current from going back to ground (even lead with shaft tower insulate).These two effects must be guaranteed.Insulator should not cause various dynamo-electric stress to lose efficacy owing to environment and electric loading condition change, otherwise insulator just can not play effect, the use and the service life of infringement whole piece circuit.
In electric power system, use usually and form insulator string by a plurality of insulators.Insulator string connects shaft tower and lead through gold utensil.Gold utensil is all kinds of devices in connection and the combination of power system, to transmit the metal-ware of machinery, electrical load or certain protective action.Insulator string mainly is made up of multi-disc porcelain or glass insulator.Deterioration or breakage take place in porcelain or glass insulator easily, therefore need in time deterioration or damaged insulator to be changed processing, and soon deterioration or damaged insulator are replaced with good insulation performance in time.
Usually use chain block to change the insulator on the shaft tower.The necessary dependent manual operation of chain block, the course of work of changing insulator is following:
Tighten up chain block and make it replace deterioration or the damaged suffered power of insulator, remove the active force that deterioration or damaged insulator receive, make deterioration or damaged insulator loosening, thereby it is sub to take off in deterioration or damaged insulator, replacings good insulation performance; Behind good insulation performance, loosen chain block in the replacing, make good insulation performance stressed, insulator string will be returned to original position.
Chain block in use, therefore chain is prone to be damaged or job-hop, and causes the chain conduction easily, comes off, and has potential safety hazard.In order to guarantee staff's safety, so in the course of work of the insulator that uses chain block replacing deterioration or breakage, the protection defence line need be set.The protection defence line is steel cable (generally using the steel wire rope of diameter as 17.5mm).When changing the insulator of deterioration or breakage, steel wire rope one end is connected shaft tower, the lead that other end connection deterioration or damaged insulator connect; When chain block damages, fracture; When causing this wire dropping, steel wire rope can be accepted the lead that comes off, and can bear corresponding impulsive force; Avoid having an accident safeguard work personnel's safety.
The protection defence line is set, and to cause changing the course of work of insulator more loaded down with trivial details, complicated, makes that the operating efficiency of changing insulator is lower.
In sum, how providing a kind of replacing insulator to use instrument, simplify the work of changing insulator, and then improve the operating efficiency of changing insulator, is present those skilled in the art's problem demanding prompt solution.
The utility model content
In view of this, the utility model provides a kind of replacing insulator to use instrument, has simplified and has changed the work of insulator, and then improved the operating efficiency of changing insulator.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of replacing insulator is used instrument, and itself and shaft tower are fixedly linked, and comprises two sub-instruments, and said sub-instrument comprises:
Be connected gold utensil with said shaft tower through what removable connector was fixedly linked;
Be connected that gold utensil links to each other and can be around the leading screw of himself axis rotation with said, said leading screw is provided with handle;
With the pull-rod of said leading screw through threaded engagement;
Four doggings that link to each other with said pull-rod, said four doggings are provided with four doggings that hook up the lead on the said shaft tower.
Preferably, above-mentioned replacing insulator is with in the instrument, and said connection gold utensil is the aerofoil profile jig.
Preferably, above-mentioned replacing insulator is with in the instrument, and said aerofoil profile jig links to each other through threaded connector with said shaft tower.
Above-mentioned replacing insulator is following with the course of work of instrument:
When need changing insulator, all be fixed on the shaft tower, be about to connect gold utensil and link to each other, four doggings of four doggings are hooked the lead on the shaft tower with shaft tower with changing the sub-instrument of insulator with instrument; The handle of rotational lead screw then; Make and move to the top of shaft tower with the pull-rod of leading screw through threaded engagement; Four doggings also move to the top of shaft tower with pull-rod simultaneously, and then make four doggings hook lead, also make that the insulator string between shaft tower and lead is lax simultaneously; After insulator string is lax, can take off the insulator that needs replacing, change good insulation performance; The handle of last rotational lead screw makes and moves to the bottom of shaft tower with the pull-rod of leading screw through threaded engagement that four doggings also move to the bottom of shaft tower with pull-rod simultaneously; And then make four doggings unclamp lead; Simultaneously make that also the insulator string between shaft tower and lead is stressed again, return to original position, finally realized the replacing insulator.Said process needs two supporting uses of sub-instrument, lays respectively at the both sides of insulator string, makes could realize changing insulator, otherwise the insulator unbalance stress can not carry out insulator stress equalization always the replacing of insulator.
The replacing insulator that the utility model provides is with in the instrument; Two supporting uses of sub-instrument have realized the replacing of insulator through gold utensil, leading screw, pull-rod and four doggings in succession, and two sub-instruments are protected the defence line each other; Got rid of potential safety hazard to a certain extent; Need not to be provided with in addition again the protection defence line, simplified and changed the work of insulator, and then improved the operating efficiency of changing insulator.
