Abstract

The utility model relates to a welding roll-over device for an oil tank of a large power transformer, which adopts the technical scheme that an angle support (1), hinge axes (2), upper support shafts (3), lower support shafts (4), a base(5), an adjusting shaft (6), an adjusting lead screw (7), and a rotational support shaft (8) are included, wherein a vertex angle of the angle support is movably connected with the base through the rotary support shaft; two sides of the angle support are respectively connected with the upper support shafts through the hinge axes; the other ends of the upper support shafts are movably connected with the lower support shafts; the other ends of the lower supports shaft are hinged with the base; two ends of the adjusting shaft are respectively hinged with one side of the angle support and the corresponding base through the hinge axes; and the adjusting lead screw is arranged in the middle of the adjusting shaft. When the roll-over device is used, the adjusting lead screw is rotated firstly, the length of the adjusting shaft can be changed through extending and retracting in order to drive the angle of the angle support to change, and corresponding horizontal welding seams on the oil tank can be welded in sequence after the oil tank is placed on a frame. The utility model has the benefits that the device can rotate left and right, so that tank walls on two sides of the oil tank can be kept in a flat state, and the welding roll-over device has the characteristics of simple structure, convenience and flexibility, safety and reliability.

Description

Large-scale power transformer fuel tank welding rollover stand
Affiliated technical field:
The utility model belongs to a kind of process equipment of regulating, particularly large-scale power transformer fuel tank welding tilter that large-size box is welded.
Background technology:
The high-power transformer fuel tank is not only the device body that holds oil filled transformer and the container of high-quality transformer oil, and is standing the effect of various mechanical forces in transformer lifting, transportation.The weldquality of fuel tank is most important, not only influences the mechanical strength of fuel tank, also influences the transformer oil seepage.
Oil tank of transformer mainly is made up of last fuel-economizing case and lower oil tank, and being welded of lower oil tank normally carried out in the assembling of fuel tank earlier, and the fuel-economizing case is gone up in assembling then.After all parts spot welding of fuel tank outside are intact, take lower oil tank apart, upper and lower fuel-economizing case was fallen once more, adjustment weld seam vantage point so that weld the weld seam that those can the downhand position, and has welded a side, welds opposite side after the upset again.
Usually oil tank of transformer is formed by the steel plate assembly welding that varies in size, and its inside and outside weld seam is crisscross, and the overwhelming majority is to leak weld seam, and the quality of weld seam has great influence to seepage oil.For guaranteeing weldquality and enhancing productivity, must take the welding manner of flat fillet weld, that is to say that conversion fuel tank angle is in both sides case lid weld seam respectively and keeps flat welding side cover and the inside and outside weld seam of end wall under the shape repeatedly.
Because the fuel tank overall dimensions are bigger, conversion fuel tank angle is adjusted position while welding, realizes that flat fillet weld is very bothersome, and the past is to hang the welding that is in a horizontal position with overhead traveling crane, and is promptly dangerous, takies overhead traveling crane again, and equipment turnover rate and production efficiency are lower.
The utility model content:
The utility model purpose provides a kind of large-scale power transformer fuel tank welding rollover stand, can rapid adjustment workpiece angle of inclination, need not to prepare the power start device, solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: large-scale power transformer fuel tank welding rollover stand comprises the angle support, hinge axis, the upper support axle, the lower support axle, base, regulating shaft, regulate leading screw, rotation support shaft, latch, the drift angle of angle support flexibly connects by rotation support shaft and base, the both sides of angle support are connected with the upper support axle by hinge axis respectively, the other end of upper support axle and lower support axle flexibly connect, the other end and the base of lower support axle are hinged, the regulating shaft two ends are hinged with the one side of angle support and corresponding base respectively by hinge axis, are provided with the adjusting leading screw in the middle of the regulating shaft.
In order to adjust the angle of inclination of angle support, on upper support axle and lower support axle, be respectively equipped with the locating hole that several and latch are complementary, both connect by latch.
During use, under fuel tank was welded the situation of turnover bracket zero load, leading screw was regulated in rotation earlier, makes regulating shaft length that telescopic variation be arranged.Drive the variation of upper support axle and lower support axle length of fit, and position by the corresponding aperture of latch insertion upper support axle and lower support axle.Therefore the angle that converts the angle support to changes.Both rotations of certain angle of workbench.Then fuel tank is placed on the support, the respective horizontal weld seam to fuel tank welds successively.
The beneficial effects of the utility model are: the utility model has improved traditional casing welding and assembling method, can left-right rotation, and make the fuel tank both sides box wall be in flat condition respectively, guaranteed welding quality.Have characteristics simple in structure, convenient, flexible, safe, reliable, both floor space was little, can move at any time again.Save fund, improved production efficiency.
Description of drawings:
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment partial sectional view;
Fig. 3 is the utility model embodiment vertical view;
Among the figure: 1. the angle support, 2. hinge axis, 3. the upper support axle, 4. the lower support axle, 5. base, 6. regulating shaft, 7. regulate leading screw, 8. rotation support shaft, 9. latch.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
With reference to accompanying drawing 1,2,3, large-scale power transformer fuel tank welding rollover stand comprises angle support 1, hinge axis 2, upper support axle 3, lower support axle 4, base 5, regulating shaft 6, regulate leading screw 7, rotation support shaft 8, latch 9, the angle support is a right angle rack, the drift angle of angle support flexibly connects by rotation support shaft and base, the both sides of angle support are connected with the upper support axle by hinge axis respectively, the other end of upper support axle and lower support axle flexibly connect, have several corresponding locating holes on upper support axle and the lower support axle, this locating hole and latch are complementary, the other end and the base of lower support axle are hinged, the regulating shaft two ends are hinged with the one side of angle support and corresponding base respectively by hinge axis, regulating shaft is two parts, be respectively equipped with and regulate the left and right sides screw that screw mandrel is complementary, two parts connect by regulating leading screw, during use, under fuel tank is welded the situation of turnover bracket zero load, leading screw is regulated in rotation earlier, makes regulating shaft length that telescopic variation be arranged.Drive the variation of upper support axle and lower support axle length of fit, and position by the corresponding aperture of latch insertion upper support axle and lower support axle.Therefore the angle that converts the angle support to changes, and the limit of angle support and the angle of base can be at 0--90 0Between adjust both rotations of certain angle of workbench.Substantially satisfy the requirement that is welded of all casings.Then fuel tank is placed on the support, to the respective horizontal weld seam welding of fuel tank, has guaranteed welding quality successively.
