Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] like Figures 1 to 3 As shown, a dry-type transformer production and assembly equipment includes an annular carrier plate and a plurality of support columns 2 equidistantly arranged on the lower side of the annular carrier plate, a plurality of slide plates 5 are arranged in the slideway on the top of the annular carrier plate, a turntable 51 for directly carrying the transformer is rotatably arranged on the slide plate 5, the annular carrier plate is composed of a C-shaped main plate 11 and a fan-shaped sub-plate 12, the fan-shaped sub-plate 12 corresponds to a slide plate 5, and a lifting device 4 is arranged on the lower side of the fan-shaped sub-plate 12. When the lifting device 4 moves the fan-shaped sub-plate 12 upward and combines it with the C-shaped main plate 11 to form a complete annular carrier plate, the slide plate 5 can slide sequentially between the fan-shaped sub-plate 12 and the C-shaped main plate 11. The lifting device 4 is a hydraulic cylinder vertically buried below the ground, and the support column 2 and the column 3 are both hydraulic cylinders arranged vertically.

[0037] A column 3 is arranged in the through hole in the middle of the annular carrier plate, and a driving cover body is rotatably arranged on the column 3 through an upper limit member 31 and a lower limit member 32. The driving cover body includes an annular plate 61 and an inner annular protrusion 63 and an outer annular protrusion 62 coaxially arranged on the lower side of the annular plate 61. The lower edge of the inner annular protrusion 63 is provided with a driving gear ring meshing with the driving gear 72, and the lower edge of the outer annular protrusion 62 is provided with a limiting pin corresponding to the limiting hole 52 on the slide plate 5; when the slide plate 5 moves to the highest position through the lifting device 4, the limiting hole 52 of the slide plate 5 is vertically plugged with the limiting pin. The driving gear 72 is arranged on the output shaft of the driving motor 71, and the driving motor 71 is arranged on the lower side of the C-shaped main board 11. The outer wall of the inner annular protrusion 63 is in a sliding fit relationship with the inner ring of the annular carrier and the inner edge of the slide plate 5, and the inner wall of the inner annular protrusion 63 is also in a sliding fit relationship with the lower limiter 32 on the lower side of the driving cover. An edge baffle 131 is provided on the upper side of the outer ring of the annular carrier to prevent the outer edge of the slide plate 5 from warping up. A fixed tooth 132 is provided on the inner side of the connecting plate body between the outer ring of the annular carrier and the edge baffle 131, and a passive gear 91 coaxial with the rotating disk 51 is provided inside the slide plate 5. The passive gear 91 is meshed with the fixed tooth 132 through a plurality of mutually meshing transmission gears 92. The fixed teeth 132 on the inner side of the connecting plate body between the outer ring of the annular carrier and the edge baffle 131 are arranged with gaps.

[0038] How it works:

[0039] The lifting device 4 retracts to move the fan-shaped sub-plate 12 down to the ground, and the transformer body 8 is first placed on the fan-shaped sub-plate 12 moved down to the ground by a sling or a forklift. The lifting device 4 moves the fan-shaped sub-plate 12 up, so that the fan-shaped sub-plate 12 and the C-shaped main plate 11 are assembled into a complete annular carrier. In this process, the limiting hole 52 of the slide plate 5 on the fan-shaped sub-plate 12 is plugged into the limiting latch on the annular protrusion 62 outside the drive cover, and the drive motor 71 drives the drive cover body to rotate through the driving gear, and the drive cover body then drives each slide plate to slide inside the slide of the annular carrier. In this process, the gear transmission structure on the slide plate can realize the rotation of the turntable 5 by meshing with the fixed teeth 132 on the annular carrier. Due to the gap setting of the fixed teeth 132, by reasonably setting the length and position of the fixed teeth 132, the rotation of the turntable 51 can be automatically realized during the movement of the slide plate 5 along the slide groove, so that the transformer body 8 is turned to the correct position at a suitable workstation, which is convenient for workers to assemble. The assembled transformer 8 ′ can be unloaded by the combination of the lifting device 4 and the fan-shaped sub-plate 12 .
