Abstract

The invention provides a transformer lifting method by which manpower and materials can be reduced, time is shortened and high security is ensured. The method is realized by utilizing a large transformer, and a crane and a steel wire rope which are used to lift the transformer, wherein a lifting hook is arranged on the crane. The method is characterized in that the steel wire rope and a chain block are used to reel and release in both horizontal and vertical directions of the transformer so as to place the transformer into a transformer room, and then the chain block is continuously used to move the transformer to the installation position. By adopting the method provided by the invention, the manpower and materials can be reduced, the time can be shortened and the security is high; and meanwhile, the difficulty of large size and heavy weight in the transformer lifting process can be solved.

Description

The transformer hanging method
Technical field
The invention belongs to electric equipment mounting technique field, be specifically related to the transformer hanging method.
Background technology
In the electric equipment installing engineering, transformer is installed the content that is absolutely necessary, because volume of transformer is big, Heavy Weight, the emphasis that the transformer lifting is often installed as electric equipment needs sufficient personnel and long time to go to finish.Therefore, we study the transformer hanging method.
Summary of the invention
Technical problem to be solved by this invention is the technical deficiency at above-mentioned existence, and a kind of reduced artificial and material are provided, and the time is short, safe transformer hanging method.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be: the transformer hanging method, include transformer, with the crane and the jack that are used to lift by crane transformer, it is characterized in that: on transformer level and vertical direction, utilize the folding and unfolding in the horizontal and vertical directions of steel wire rope and jack, transformer is placed in the transformer room, and continues to utilize jack, transformer is moved to the installation site.
In such scheme, described jack has three, wherein jack one end is fixed on the transformer indoor wall, the other end is connected the side of transformer bottom, No. two, No. three jack one end is connected on the suspension ring of transformer top, the other end hangs in the hook of crane, and make No. two, No. three jacks be in the transformer installation direction near transformer room's one side, crane rises to collude and makes steel wire rope and No. two, No. three jacks transformer of slinging simultaneously, and adjustment jack length, making transformer is horizontal level, and transformer is slowly moved to the limit, transformer room safely.
When treating in the transformer one side lower margin channel-section steel inlet chamber 200mm, cross transformation body bottom tub steel link to each other with a jack (figure two) with steel wire rope or hanging belt bag, tighten up jack No. one, slowly loosen No. two, No. three simultaneously jack, crane colludes simultaneously and slowly descends, and it is indoor that transformer integral body is steadily moved on to.
All unclamp No. two, No. three jacks the back in the whole inlet chamber of transformer, take off No. two, No. three and lead chain, No. one jack continues to tighten up, crane pine simultaneously colludes, after treating in the whole inlet chambers of transformer lower margin channel-section steel, the steel wire rope of crane is taken off (figure three), confirm the mounting distance about transformer, continue transformer to be moved to the installation site with a jack.Confirm about transformer on inspection and the accurate back installation of the mounting distance of front and back.
This practical approach it should be noted that No. one, No. two, No. three jacks will cooperate simultaneously with crane.In the time of the tension of jack, No. two, No. three jacks will cooperate simultaneously with crane and loosen, and when No. two, No. three jacks and crane loosen simultaneously, note confirming the level of transformer, can not tilt.
Principle of the present invention is: in the vertical direction utilizes steel wire rope and jack lifting, in the horizontal direction, utilizes jack to move, and earlier the part of transformer is put into the ground location of transformer room, slowly pulls the design and installation position into jack then.
Beneficial effect of the present invention is: reduced artificial and material, the time is short, and is safe, makes lifting volume of transformer difficulty big, Heavy Weight obtain solution.

Among the figure: 1-transformer, 2-steel wire rope, No. two jacks of 3-, No. three jacks of 4-, jack of 5-.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing:
As Fig. 1 Fig. 2 Fig. 3 and transformer hanging method shown in Figure 4, include transformer 1, with the crane and the steel wire rope 2 that are used to lift by crane transformer 1, wherein on transformer 1 level and vertical direction, be provided with jack, utilize the folding and unfolding in the horizontal and vertical directions of steel wire rope 2 and jack, transformer 1 is placed in the transformer room, and continue to utilize jack, transformer 1 is moved to the installation site.
In the present embodiment, described jack has three covers, wherein jack 5 one ends are fixed on 100mm place on the transformer indoor wall, the other end is connected transformer 1 side, No. two jacks 3 and No. three jack 4 one ends are connected on the transformer 1 top suspension ring, the other end hangs in the hook of crane, and make No. two jacks 3 and No. three jacks 4 be in transformer 1 installation direction near transformer room's one side, crane rises to collude and makes steel wire rope 2, No. two jacks 3 and No. three jacks 4 transformer 1 of slinging simultaneously, and adjustment jack length, make transformer 1 be horizontal level, and transformer 1 is slowly moved to the limit, transformer room safely.
When treating in the transformer 1 one side lower margin channel-section steel inlet chambers 200mm, crossing transformer 1 body base channel-section steel with steel wire rope 2 or hanging belt bag links to each other with a jack 5, tighten up jack 5 No. one, slowly loosen simultaneously No. two jacks 3 and No. three jacks 4, crane colludes simultaneously and slowly descends, and makes transformer 1 integral body steadily move on to indoor.
All unclamp No. two jacks 3 and No. three jacks 4 back in the transformer 1 whole inlet chamber, take off No. two jacks 3 and No. three jacks 4, leading chain 5 No. one continues to tighten up, crane pine simultaneously colludes, after treating in the whole inlet chambers of transformer 1 lower margin channel-section steel, the steel wire rope 2 of crane is taken off, confirm the mounting distance of transformer about 1, continue transformer 1 to be moved to the installation site with a jack 5.Confirm the accurate back installation of mounting distance of transformer about 1 and front and back on inspection.
This practical approach it should be noted that No. one, No. two, No. three jacks will cooperate simultaneously with crane.In the time of 5 tensions of jack, No. two jacks 3 and No. three jacks 4 will cooperate simultaneously with the hook of crane and loosen, and when the hook of No. two jacks 3 and No. three jacks 4 and crane is loosened simultaneously, note confirming the level of transformer 1, can not tilt.
This method is applicable to 2000kVA and following transformer lifting.
