Description

Technical Field

[0001] This invention relates to a dry-type transformer production and assembly equipment, belonging to the technical field of dry-type transformer production equipment. Background Technology

[0002] Traditional dry-type transformer assembly is carried out directly on the ground. The assembled transformer cannot rotate or be raised and lowered on its own. During the assembly process, the assemblers not only need to bend over many times, but also need to walk around the transformer repeatedly, which has the disadvantages of low assembly efficiency and high labor intensity for workers. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of traditional dry-type transformer assembly, which is time-consuming and labor-intensive, by providing a dry-type transformer production and assembly equipment. The height of this dry-type transformer assembly equipment can be adjusted as needed. During the assembly process, the equipment can also automatically rotate the transformer, which facilitates the assembly of various parts of the transformer by workers. It has the advantages of high assembly efficiency and low labor intensity for workers.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A dry-type transformer production and assembly equipment includes an annular carrier plate and several support columns equidistantly arranged on the lower side of the annular carrier plate. Several slide plates are arranged in the slide rails at the top of the annular carrier plate. A turntable for directly supporting the transformer is rotatably arranged on the slide plate. The annular carrier plate is composed of a C-shaped main plate and a sector-shaped sub-plate. Each sector-shaped sub-plate corresponds to a slide plate. A lifting device is provided on the lower side of the sector-shaped sub-plate. When the lifting device moves the sector-shaped sub-plate up and assembles it with the C-shaped main plate to form a complete annular carrier plate, the slide plate can slide sequentially between the sector-shaped sub-plate and the C-shaped main plate.

[0006] By adopting the above technical solution, a dry-type transformer production and assembly equipment is provided. During the assembly process, the dry-type transformer assembly equipment can first lift the main body of the transformer to a height suitable for workers to assemble, and then rotate the transformer as needed, which facilitates the workers to assemble the components of the transformer in various positions. It has the advantages of high assembly efficiency and low labor intensity for workers.

[0007] A further feature of the present invention is that a column is provided in the through hole in the middle of the annular carrier plate, and a drive cover is rotatably mounted on the column via an upper limit member and a lower limit member. The drive cover includes an annular plate and an inner annular protrusion and an outer annular protrusion arranged concentrically on the lower side of the annular plate. A drive gear ring that meshes with a drive gear is provided on the lower edge of the inner annular protrusion, and a limit pin that corresponds to the limit hole on the slide plate is provided on the lower edge of the outer annular protrusion. When the slide plate is moved to the highest position by the lifting device, the limit hole of the slide plate and the limit pin are vertically connected.

[0008] By adopting the above technical solution, a specific method for driving the skateboard is provided. This method is organically combined with the lifting device and can directly limit the skateboard that has moved to the top, so as to facilitate the subsequent uniform rotational driving of all skateboards.

[0009] A further configuration of the present invention is as follows: the drive gear is mounted on the output shaft of the drive motor, and the drive motor is mounted on the lower side of the C-shaped main board.

[0010] By adopting the above technical solution, the specific placement method of the drive motor for the drive gear is defined.

[0011] A further feature of the present invention is that the outer side wall of the inner annular protrusion is in a sliding fit with the inner ring of the annular carrier plate and the inner edge of the slide plate, and the inner side wall of the inner annular protrusion is also in a sliding fit with the lower limit member on the lower side of the drive cover.

[0012] By adopting the above technical solution, the inner annular protrusion and the inner and outer accessories are set to a sliding fit relationship, which effectively improves the structural stability.

[0013] A further feature of the present invention is that an edge baffle is provided on the upper side of the outer ring of the annular carrier plate to prevent the outer edge of the slide from curling up.

[0014] By adopting the above technical solution, an edge baffle is set on the outer ring of the annular carrier plate. The edge baffle can effectively prevent the outer edge of the skateboard from curling up due to the pressure of the limiting pin.

[0015] A further feature of the present invention is that a fixed tooth is provided on the inner side of the connecting plate between the outer ring of the annular carrier plate and the edge baffle, and a driven gear coaxial with the turntable is provided inside the slide plate. The driven gear is connected to the fixed tooth through multiple meshing transmission gears.

[0016] By adopting the above technical solution, a transmission structure for passively driving the turntable to rotate is set between the slide plate and the annular carrier plate. This design can realize the automatic rotation of the turntable during the sliding of the slide plate. By effectively utilizing the rotation of the turntable, the assembly of various components of the transformer can be realized. This design is novel and ingenious, eliminating the need for an additional rotation drive device for the rotation of the turntable, and has outstanding practicality.

[0017] A further feature of the present invention is that the fixing teeth on the inner side of the connecting plate between the outer ring of the annular carrier plate and the baffle are arranged with gaps.

[0018] By adopting the above technical solution and arranging the fixed teeth at intervals, the rotation angle of the turntable can be effectively controlled during the movement of the slide plate, which facilitates the reasonable arrangement of assembly stations for different components on the outside of the annular carrier plate.

[0019] A further feature of the present invention is that the lifting device is a hydraulic cylinder vertically buried below ground level.

[0020] By adopting the above technical solution, the specific design of the lifting device was defined.

[0021] A further feature of the present invention is that both the support column and the upright column are vertically arranged hydraulic cylinders.

[0022] By adopting the above technical solution, the assembly equipment can be made to adjust its height arbitrarily.

[0023] The main beneficial effects of this invention are:

[0024] 1. The dry-type transformer assembly equipment of the present invention can first lift the main body of the transformer to a height suitable for workers to assemble during the assembly process, and then rotate the transformer as needed, which facilitates the workers to assemble the components of the transformer in various positions. It has the advantages of high assembly efficiency and low labor intensity for workers.

[0025] 2. The dry-type transformer assembly equipment of the present invention sets the inner annular protrusion and the inner and outer accessories to a sliding fit relationship, which effectively improves the structural stability.

[0026] 3. The dry-type transformer assembly equipment of the present invention has an edge baffle on the outer ring of the annular carrier plate. The edge baffle can effectively prevent the outer edge of the slide plate from lifting up due to the pressure of the limiting pin.

[0035] Example 1:

[0036] like Figures 1 to 3 As shown, a dry-type transformer production and assembly equipment includes an annular carrier plate and several support columns 2 equidistantly arranged on the lower side of the annular carrier plate. Several sliding plates 5 are arranged in a slide rail at the top of the annular carrier plate. A turntable 51 for directly supporting the transformer is rotatably mounted on each sliding plate 5. The annular carrier plate is composed of a C-shaped main plate 11 and fan-shaped auxiliary plates 12, with each fan-shaped auxiliary plate 12 corresponding to one sliding plate 5. A lifting device 4 is provided on the lower side of the fan-shaped auxiliary plate 12. When the lifting device 4 moves the fan-shaped auxiliary plate 12 upwards and assembles it with the C-shaped main plate 11 to form a complete annular carrier plate, the sliding plate 5 can slide sequentially between the fan-shaped auxiliary plate 12 and the C-shaped main plate 11. The lifting device 4 is a vertically buried hydraulic cylinder, and the support columns 2 and columns 3 are also vertically arranged hydraulic cylinders.

[0037] A column 3 is installed in the through hole in the middle of the annular carrier plate. A drive cover is rotatably mounted on the column 3 via an upper limit member 31 and a lower limit member 32. The drive cover includes an annular plate 61 and an inner annular protrusion 63 and an outer annular protrusion 62 concentrically located on the lower side of the annular plate 61. The lower edge of the inner annular protrusion 63 is provided with a drive gear ring that meshes with the drive gear 72. The lower edge of the outer annular protrusion 62 is provided with a limiting pin that corresponds to the limiting hole 52 on the slide plate 5. When the slide plate 5 is moved to the highest position by the lifting device 4, the limiting hole 52 of the slide plate 5 and the limiting pin are vertically engaged. The drive gear 72 is mounted on the output shaft of the drive motor 71, which is mounted on the lower side of the C-shaped main plate 11. The outer wall of the inner annular protrusion 63 is in a sliding fit with the inner ring of the annular carrier plate and the inner edge of the slide plate 5. The inner wall of the inner annular protrusion 63 is also in a sliding fit with the lower limit member 32 on the lower side of the drive housing. An edge baffle 131 is provided on the upper side of the outer ring of the annular carrier plate to prevent the outer edge of the slide plate 5 from warping upwards. A fixing tooth 132 is provided on the inner side of the connecting plate between the outer ring of the annular carrier plate and the edge baffle 131. A driven gear 91, coaxial with the turntable 51, is provided inside the slide plate 5. The driven gear 91 is connected to the fixing tooth 132 through multiple meshing transmission gears 92. The fixing teeth 132 on the inner side of the connecting plate between the outer ring of the annular carrier plate and the edge baffle 131 are spaced apart.

[0038] Operating principle:

[0039] The lifting device 4 retracts, causing the fan-shaped sub-plate 12 to move down to the ground. Using a hoist or forklift, the transformer body 8 is first placed on the fan-shaped sub-plate 12 that has moved down to the ground. The lifting device 4 then 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 plate. During this process, the limiting hole 52 of the sliding plate 5 on the fan-shaped sub-plate 12 is engaged with the limiting pin on the annular protrusion 62 on the outer side of the drive cover. The drive motor 71 drives the drive cover to rotate through the drive gear. The drive cover then drives each sliding plate to slide within the slide of the annular carrier plate. During this process, the gear transmission structure on the sliding plate can realize the rotation of the turntable 51 by meshing with the fixed teeth 132 on the annular carrier plate. Due to the gap setting of the fixed teeth 132, by reasonably setting the length and position of the fixed teeth 132, the turntable 51 can be automatically rotated during the movement of the sliding plate 5 along the slide groove, thereby enabling the transformer body 8 to rotate to the correct position in the appropriate work position, which is convenient for workers to assemble. After assembly, the transformer 8′ can be unloaded by a combination of lifting device 4 and sector-shaped auxiliary plate 12.
