Abstract
The utility model relates to a lifting tool, in particular to an auxiliary lifting tool for an on-load switch of a large transformer, which is applicable for the lifting operation of the on-load switch of the large transformer and similar lifting operations. The auxiliary lifting tool for the on-load switch of the large transformer has the following structural features: the auxiliary lifting tool for the on-load switch of the large transformer includes a cuboid steel plate, two lifting rings, and four cylindrical steel columns, wherein the two lifting rings are mounted on the lower bottom surface of the cuboid steel plate, and the distance between the lifting rings corresponds to the lifting center of gravity; the four cylindrical steel columns are mounted at the four corners of the lower bottom surface of the cuboid steel plate, and the distribution positions of the four cylindrical steel columns are matched with the diametral edges of an inner barrel of the on-load switch. When used for the lifting of the on-load switch, the tool can not only steadily and effectively take out the on-load switch, but also totally ensure that parts of the on-load switch are not damaged during the lifting on the basis of correct operations and use. The auxiliary lifting tool for the on-load switch of the large transformer greatly improves the overhauling or replacement efficiency for the on-load switch of the large transformer, shortens the work time, ensures the completion of overhauling during the overhauling period, and improves the power supply reliability.
Description
Technical field
The utility model relates to a kind of lifting tool, a kind of loaded switch lifting tool particularly, and it is applicable to high-power transformer loaded switch lifting operation and similar lifting operation.
Background technology
Generally, when high-power transformer loaded switch has service work maybe to need to change, need to be by the whole taking-up of loaded switch body, because loaded switch body is built in voltage transformer, if loaded switch is taken out with hand, not only to consider the weight of loaded switch, needing many people to coordinate mentions, and may be due to personnel's carelessness, in taking-up process, cause rocking of loaded switch, damage parts, virtually increased work capacity, may cause engineering extension, power transmission not in time, affect power supply quality.If therefore can loaded switch be hung out with weight-lifting equipment, will greatly simplify maintenance step and quantities.But because loaded switch is inner without special suspension ring and lifting hole(eyelet), and the basic fibrous glass winding cylinder that adopts in loaded switch inside, the binding point of applicable lifting, does not bundle lifting by force, will damage loaded switch.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and proposes a kind of easy and simple to handle, reliable, time saving and energy saving high-power transformer loaded switch lifting accessory appliances.
The utility model is realized by following approach:
High-power transformer loaded switch lifting accessory appliances, its structural feature is, include a cuboid steel plate, two suspension ring and four cylindrical steel columns, two suspension ring are arranged on the bottom surface of cuboid steel plate, interval between suspension ring is corresponding with lifting center of gravity point, and four cylindrical steel columns are arranged on the position, four angles of the bottom surface of cuboid steel plate, and its distributing position and loaded switch inner diameter of steel flue edge are suitable.
When lifting is used, remove loaded switch top flange, high-power transformer loaded switch lifting tool is tilted to put into loaded switch inner core, then ajust high-power transformer loaded switch lifting tool, four spacing cylinders will match and get togather with loaded switch inner diameter of steel flue edge, thereby fix loaded switch.Again the suspension ring on weight-lifting equipment rope and high-power transformer loaded switch lifting tool are tied to locking, by weight-lifting equipment, loaded switch is sling, easy and simple to handle, reliable, thereby play, simplify work capacity, loaded switch energy pulsation-free taken out and guaranteed and can not damage the effect of each parts of loaded switch.
The utility model can further be specially:
Two suspension ring are fixedly locked in cuboid steel plate by nut assembly.
Can be in cuboid bilateral symmetry lifting center of gravity point boring, then the nut assembly that nut, spring leaf, pad by corresponding size form is locked cuboid steel plate by suspension ring.
The long limit of cuboid steel plate is straight line, and broadside is arc-shaped surface, and the outer-diameter circular arc face of this arc-shaped surface and loaded switch inner core is adaptive.
Like this, can facilitate cuboid steel plate to stretch in the inner core of loaded switch, and be unlikely to and its friction, cause damage.
Four limits of cuboid steel plate are smooth side, or the edge part on four limits is bent downwardly folding.
Four limits of cuboid steel plate all need to polish smooth, in unlikely lifting process because loaded switch inner core is lost in friction.Or its edge part can be bent downwardly foldingly, with this, keep the smooth of four limits.
In sum, the utility model provides a kind of high-power transformer loaded switch lifting accessory appliances.Use this instrument lifting loaded switch, can not only steadily effectively take out loaded switch, and under correct operation is used, can guarantee can not damage in lifting process the parts of loaded switch completely.The work efficiency that has greatly improved the maintenance of high-power transformer loaded switch or changed, has shortened work-hours, has guaranteed within turn(a)round, to complete service work, has promoted power supply reliability.
Accompanying drawing explanation
Figure 1 shows that the structural representation of high-power transformer loaded switch lifting accessory appliances described in the utility model.
Figure 2 shows that the birds-eye view of Fig. 1.
Figure 3 shows that the back view of Fig. 1.
Below in conjunction with accompanying drawing, the utility model is described further.
The specific embodiment
Most preferred embodiment:
With reference to accompanying drawing 1, Fig. 2 and Fig. 3, high-power transformer loaded switch lifting accessory appliances, includes 1, two suspension ring 2 of a cuboid steel plate and four cylindrical steel columns 3, two suspension ring 2 are arranged on the bottom surface of cuboid steel plate 1, by nut assembly 4, fixedly lock in cuboid steel plate 1.Interval between suspension ring 2 is corresponding with lifting center of gravity point, and four cylindrical steel columns 3 are arranged on the position, four angles of the bottom surface of cuboid steel plate 1, and its distributing position and loaded switch inner diameter of steel flue edge are suitable.
Concrete: cuboid steel plate 1 is the zinc-plated carbon steel of the thick 450 * 210mm of 5mm, take oblong center as round dot, and center is that radius carries out circular arc cutting to rectangular broadside, and cut surface need polish smooth.By 5mm place, both sides, the long limit of the zinc-plated carbon steel of oblong, to crooked 90 degree of reverse side, side is as smooth side.Take oblong center as round dot, and radius 20mm does circle, circle with cut after crossing 4 points of oblong diagonal line hammer into the cylinder 3 of 4 diameter 5mm, as limit point.After cutting completes oblong center and the bilateral symmetry center-point of oblong broadside hole respectively, and lock the suspension ring 2 of M24.
It is same as the prior art that the utility model is not stated part.
