Abstract
The utility model discloses a rotating apparatus of transformer body, which is characterized in that: it comprises an inner fixed holding ring and an outer rotatable supporting ring sleeved outside; symmetrical semicircle grooves are formed between the two along radial direction, the two semicircle grooves are inosculated with each other to form a circular ring cavity; steel balls are filled in the cavity; the inner fixed holding ring and the outer rotatable supporting ring sleeved outside are fixed with each other by a block ring, and are integrated into one piece by an axial connection; the upper end face of the outer rotatable supporting ring is slightly higher than the upper end face of the inner fixed holding ring; and the upper end face of the outer rotatable supporting ring is connected with a bearing plate.
Description
Technical field
The utility model relates to a kind of station service transformer makes its body rotation when maintenance device.
Background technology
The transformer that the power station goes wrong is when maintenance, because after withdrawing from the basis, the transformer of standby phase need be pushed into the basis, in the process that withdraws from and push, need 90 ℃ of transformer rotations sometimes, go wrong as transformer when 1,4,7 any operation, when needing maintenance, need transport to the position of No. 11 standby phase transformer, could repair, and with No. 11 standby replace mutually (Fig. 1).The long axis direction that can see transformer need after twice rotation, just can arrive the place of No. 11 standby phases in 2,5,8,10 positions.
Method commonly used now is: after the scene is moved back transformer or be pushed into 2,5,8,10 positions along track, the transformer of jack-uping, two blocks of steel plates are put in fuel tank bottom at transformer, and between two block plates, coat a large amount of butter, utilize the hoisting equipment of far-end, simultaneously transformer is drawn, in operating process, utilize the frictional force between the steel plate, with 90 ℃ (Fig. 2) of transformer body rotation.
The shortcoming of above method: at first, in the selection of steel plate, have higher requirements, the surface smoothness of steel plate reaches not instructions for use, can cause in the rotary course local location in projection of two block plates stressed mutually, the influence rotation.The second, two block plate owing to the internal structure reason of transformer, can cause the unbalance stress of steel plate after place the transformer bottom, transformer deviation of gravity center during rotation if just rotate to the raised position of article one, can cause very big difficulty.The 3rd, adopt said method, can take great amount of manpower and material resources, and the weak effect of rotation, it is stressed temporarily to occur using jack sometimes, just can deal with problems.
Summary of the invention
The purpose of this utility model is to provide a kind of whirligig, and it is on-the-spot because body is overweight in the power station to solve transformer, the rotation difficulty, and great amount of manpower and material resources is saved in the especially inconvenience that is brought in the process that enters or withdraw from the basis.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of whirligig of transformer body, it is characterized in that, comprise the internal fixation retaining ring and be enclosed within the inner rotary support ring of its periphery that the two along the circumferential direction has symmetrical half slot between radially, form the annulus chamber after two half slots match, wherein be covered with steel ball; Fixedly to carry out axial restraint by back-up ring between axially as a whole for retaining ring and the inner rotary support ring that is enclosed within its periphery, and make inner rotary support ring upper surface a little more than internal fixation retaining ring upper surface, and inner rotary support ring upper surface is connected with bearing plate.
In the such scheme, described back-up ring comprises the shaft block ring that is fixed on internal fixation retaining ring external diameter bottom, the hole back-up ring that is fixed on inner rotary support ring internal diameter top.Described inner rotary support ring circumferentially uniformly has an axial connecting through hole along it, by soket head cap screw inner rotary support ring upper surface is connected with bearing plate.
The utility model has the advantages that, adopt the slewing equipment of similar bearing, by self rotating of steel ball (ball that is equivalent to bearing), the weight of transformer is evenly distributed in each steel ball, each steel ball stressed very little uses very little external force just can easily very heavy transformer be rotated to the position of any needs.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Fig. 1 is the station service transformer location drawing.
Fig. 2 releases or the pushing style schematic diagram for the prior art transformer.Among the figure: 12, traction track; 13, transformer body; 14, steel wire rope; 15, hoisting equipment.
Fig. 3 is a structural representation of the present utility model.Among the figure: 101, shaft block ring; 102, internal fixation retaining ring; 103, hole back-up ring; 104, steel ball; 105, inner rotary support ring; 106, bearing plate.
Embodiment
As shown in Figure 3, adopt a kind of bearing-type slew gear, the annulus that in this bearing, uses two kinds of diameters to cooperate: internal fixation retaining ring 102 and the inner rotary support ring 105 that is enclosed within its periphery, the two along the circumferential direction has symmetrical half slot between radially, after matching, two half slots form the annulus chamber, wherein be covered with steel ball 104, in the annulus chamber, self roll, realize the relative rotation of two rings by steel ball.Fixedly retaining ring and the inner rotary support ring that is enclosed within its periphery are connected by back-up ring between axially, make inner rotary support ring upper surface a little more than internal fixation retaining ring upper surface, and inner rotary support ring upper surface is connected with bearing plate 106.Back-up ring comprises the shaft block ring 101 that is fixed on internal fixation retaining ring external diameter bottom, the hole back-up ring 103 that is fixed on inner rotary support ring internal diameter top.Inner rotary support ring 105 circumferentially uniformly has an axial connecting through hole along it, by soket head cap screw inner rotary support ring upper surface is connected with steel plate 106.
After the transformer body jack-uped, be placed on the bearing plate 106 of this device, bearing plate 106 can be made with steel plate, the direction that transformer rotates is on demand implemented traction, internal fixation retaining ring 102 and inner rotary support ring 105 just produce the opposite rotation of direction in the circumference, have just realized the rotation of transformer body easily.
