Abstract

The utility model discloses a special platform for replacement of oil-submerged pumps of transformers. The special platform comprises an article bearing platform, a lifting jack and a sliding base, wherein the lifting jack is fixed between the article bearing platform and the sliding base. The special platform is characterized in that the sliding base is placed in a sliding groove and slides along the sliding groove, stand columns are respectively fixed at four corners of the sliding base, sliding sleeves are sleeved on the stand columns, and the top ends of the sliding sleeves are fixed at corners of the article bearing platform. The special platform for the replacement of the oil-submerged pumps of the transformers is simple in structure, low in cost and easy to operate. When the oil-submerged pumps of the transformers are disassembled, the special platform replaces manpower and supports the oil-submerged pumps. Besides, the special platform is convenient to move, so difficulty of the replacement of the oil-submerged pumps is lowered, and meanwhile, the fact that workers are free from injury in a construction process is guaranteed.

Description

The transformer oil-immersed pump is changed dedicated platform

Technical field

The utility model relates to the aid of using when a kind of transformer oil-immersed pump is changed, a kind of transformer oil-immersed pump is changed dedicated platform specifically, more change jobs the risk that is injured when reducing staff's operation so that in narrow space, conveniently carry out oil-immersed pump.

Background technology

The 220kV transformer is in running, because the electric pressure height of conversion, iron core is big by the magnitude of current, tends to produce a large amount of heats, and therefore the radiating effect to its cooling system requires very high in the 220kV transformer course of work.At present; the compulsory type oil circulated air cooling systems that are to use of totally 6 220kV transformers in station, Laiwu Power Supply Company 220kV chess mountain, station, 220kV steel city, the station, 220kV Changshao; its heat radiation is main to rely on the heat radiation that circulates of the oil-immersed pump driving transformer body of fin bottom attaching and the insulating oil in the fin; because oil-immersed pump is in the long-time running state; especially working strength maximum when summer high temperature; cause the oil-immersed pump fault to stop transport through regular meeting; if untimely replacing oil-immersed pump can cause the 220kV transformer to be stopped transport because of air-cooled fault, cause serious electric network fault.In the work of daily replacing 220kV transformer oil-immersed pump, because oil-immersed pump generally is positioned at the fin bottom, the space, present position is narrow and small, add that the oil-immersed pump own wt is big, in reality more changes jobs, usually need three in small space, to hold oil-immersed pump by manpower to four-player and unload assembling, very easily the staff caused weight extruding injury, thus oil-immersed pump to change work difficulty very big.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, with low cost, simple operation, alternative manpower carrying oil-immersed pump weight, reduction personnel workload and injured risk, be applicable to narrow and small working environment simultaneously, be convenient to move, reduce the transformer oil-immersed pump replacing dedicated platform that oil-immersed pump is changed work difficulty.

In order to reach above purpose, the technical scheme that the utility model adopts is: this transformer oil-immersed pump is changed dedicated platform, comprise objective table, jack and slide, jack is fixed between objective table and the slide, it is characterized in that: slide is placed in the chute, and slides along chute, the fixing upper pillar stand respectively in four bights of slide, be arranged with sliding sleeve on the column, the top of sliding sleeve is fixed on the bight of objective table.

Four edges of described objective table are the fixing sleeve pipe of going up respectively, argues for the sake of arguing and inserts in the sleeve pipe, is provided with a through hole at the middle part of objective table.

The beneficial effects of the utility model are: operation simple in structure, with low cost, easy, when dismounting transformer oil-immersed pump, substitute manpower and in small space, hold oil-immersed pump, and be convenient to mobile, reduce oil-immersed pump and change work difficulty, the safeguard work personnel escape injury in work progress simultaneously.

Fig. 2 is structure schematic top plan view of the present utility model;

Among the figure: 1, objective table; 2, jack; 3, slide; 4, column; 5, sliding sleeve; 6, sleeve pipe; 7, argue for the sake of arguing; 8, chute; 9, through hole.

The specific embodiment

Make the utility model with reference to accompanying drawing 1, Fig. 2.This transformer oil-immersed pump is changed dedicated platform, comprise objective table 1, jack 2 and slide 3, jack 2 is fixed between objective table 1 and the slide 3, it is characterized in that: slide 3 is placed in the chute 8, and along chute 8 slips, the fixing upper pillar stand 4 respectively in four bights of slide 3 is arranged with sliding sleeve 5 on the column 4, the top of sliding sleeve 5 is fixed on the bight of objective table 1.

Four edges of described objective table 1 are the fixing sleeve pipe 6 of going up respectively, argues for the sake of arguing in the 7 insertion sleeve pipes 6, is provided with a through hole 9 at the middle part of objective table 1.

As a kind of improvement, the bottom of slide 3 is provided with roller, and it is mobile in chute 8 to be beneficial to slide 3.

When using the utility model, the utility model is put into below the oil-immersed pump of radiating fin of transformer bottom, objective table 1 alignment oil-immersed pump bottom, through hole 9 is aimed at the outstanding nut in oil-immersed pump bottom, like this, after oil-immersed pump is put on the objective table 1, nut is inserted in the through hole 9, ensure that oil-immersed pump can be placed on the objective table 1 stably, rising jack 2 makes objective table 1 hold oil-immersed pump to suitable height, after the connecting bolt between oil-immersed pump and fin being removed again, regulating jack 2 again reduces, spur slide 3 then and in chute 8, slide, objective table 1 is hauled out together with oil-immersed pump, in the time of assembling step carried out conversely getting final product, in the dismounting transportation, the staff will argue for the sake of arguing and 7 insert the movement of carrying out objective table 1 and oil-immersed pump in the sleeve pipes 6.
