Description
Technical field
The utility model relates to transformer service technique field, particularly the special-purpose maintenance of a kind of 66kV disconnector suspender.
Background technology
At present, what for overhaul 66kV disconnector, use in system is split hoisting technology, and at operation field, to the operation that carries out large repairs of disintegration disconnector, this kind of mode of operation requires that production time is long, physical demands is larger.For changing, 66kV disconnector needs to have a power failure, lease crane operation, has also increased operating cost when having reduced the power supply reliability of system.
Summary of the invention
Technical problem to be solved in the utility model is to provide the special-purpose maintenance of a kind of 66kV disconnector suspender, replaces crane operation, and realizes hot line work.
For achieving the above object, the utility model is realized by the following technical solutions:
The special-purpose maintenance of a 66kV disconnector suspender, comprises base, column, pillar, crossbeam, reinforcement and electric block; Wherein the suspension hook of electric block is arranged on crossbeam front end, electric block body is arranged on pillar, crossbeam is fixedly connected with and is provided with reinforcement with pillar, column is connected by pressure bearing with pillar, pressure bearing arranges sealing guard shield outward, one side of sealing guard shield is provided with oil hole, and column is fixed on base, and base is connected to form by clevis bolt and angle steel.
Described base is fixed on 66kV disconnector framework, and clevis bolt is connected the comfort feature that meets stability and installation with angle steel.
Described pressure bearing is at the connecting bridge of column and pillar, the utilization of pressure bearing is brought into play the alerting ability of suspender to greatest extent, use the service life of fully enclosed device for prolonging pressure bearing, and leave oil hole in a side of seal bootr, in the situation that not destroying seal bootr, complete the maintenance work of pressure bearing.
Compared with prior art, the beneficial effects of the utility model are:
The special-purpose maintenance of a 66kV disconnector suspender, is improved the operation scheme of overhaul 66kV disconnector, from scene disintegration overhaul, is improved to whole group of replacing, and manpower is improved to electric power, has reduced laborer's labour intensity.The working parameters such as the efficiency of whole maintenance suspender, stability, the biggest lifting capacity have obtained great lifting, unpredictalbe risk of having avoided on-the-spot disintegration overhaul to cause, changing 66kV disconnector does not need bus to have a power failure, crane need not be leased and replacing operation can be completed, lower recondition expense, completed uninterrupted operation.
The utility model cost is low, and stability is strong, and it is convenient to install, and meets the stability requirement of whole device and lifting object after maximum hoisting and hanging completely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-base 2-column 3-pillar 4-crossbeam 5-reinforcement 6-electric block 7-controller 8-pressure bearing 9-sealed shield 10-suspension hook 11-U type bolt 12 nut 13-angle steel
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further illustrated:
As shown in Figure 1, the special-purpose maintenance of a kind of 66kV disconnector suspender, comprises base 1, column 2, pillar 3, crossbeam 4, reinforcement 5 and electric block 6; Wherein the suspension hook of electric block 6 is arranged on crossbeam 4 front ends, electric block 6 bodies are arranged on pillar 3, crossbeam 4 is fixedly connected with and is provided with reinforcement 5 with pillar 3, column 2 is connected by pressure bearing 8 with pillar 3, the outer sealing guard shield 9 that arranges of pressure bearing 8, one side of sealing guard shield 9 is provided with oil hole, and column 2 is fixed on base 1, and base 1 is connected to form by clevis bolt 11 and angle steel 13.
The 400Kg minisize electric hoist that described electric block 6 selects Hebei Kun Da weight-lifting equipment Co., Ltd to produce, lifting height 6/12m, horsepower input 980w.
Described pressure bearing is selected thrust ball bearing 8210, internal diameter 50mm, external diameter 78mm.
Embodiment: use the special-purpose maintenance of 66kV disconnector suspender in Dai Jiagou 220kV substation, Dai Jiagou 220kV substation needs 100 groups of 66kV disconnectores of overhaul altogether, autumn in 2013 inspection and spring in 2014 inspection have completed the heavy repair task of 55 groups of GW5 type disconnectores.Concrete operation step is as follows:
1) 2 operators pull down the clevis bolt of the special-purpose maintenance of a kind of 66kV disconnector suspender, and angle steel is attached on 66kV disconnector framework, and clevis bolt is installed, and fastening nut, completes the assembling of whole group of suspender.
2) electric block is connected to 220V source of AC, by list
peopleoperation control is sling whole group of 66kV disconnector.
3) whole group of 66kV disconnector is lifted to and requires height, by another people's rotation post of one man operation controller, arrive and specify position, whereabouts.
4) operation control is placed ground by 66kV disconnector.
The beneficial effects of the utility model in embodiment:
1, the application of the special-purpose maintenance of 66kV disconnector suspender, has made one group of 66kV disconnector heavy repair task shorten to 3 hours by original 5 hours, shortens working hours 40%, has improved work efficiency.
2, greatly reduce the manual labor in operation process, the special-purpose maintenance of 66kV disconnector suspender has reduced operating personnel's labour intensity, and electric lifting tool has greatly been saved manpower and financial resources.
3, the risk occurring in 66kV disconnector heavy repair task process has been evaded in the application of the special-purpose maintenance of 66kV disconnector suspender greatly, has reduced the possibility that unforeseeable fault occurs.
4, use the operation of the special-purpose maintenance of 66kV disconnector suspender can realize uninterrupted operation, not limited by landform, the saving of crane cost and shortening power off time will bring great economic benefit.
Above described in be only groundwork of the present utility model, not the utility model is imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
