Description

Technical Field

[0001] This invention relates to the field of transformer installation technology, and specifically to a method for installing dry-type transformers. Background Technology

[0002] Dry-type transformers are transformers whose cores and windings are not immersed in insulating oil. They are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery equipment, and other places.

[0003] Dry-type transformers are typically installed between two vertical utility poles. In existing technology, when installing a transformer, the mounting frame is first fixed between the poles, and then the transformer is lifted and fixed onto the mounting frame. Due to the large weight of the transformer, its position needs to be adjusted when it is fixed onto the mounting frame. This adjustment is inconvenient when working at heights. Because the transformer is lifted for installation, the shaking of the transformer during the installation process can cause personnel to fall. Furthermore, if the transformer is not yet fixed onto the mounting frame after being lifted, it may fall and be damaged. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a method for installing dry-type transformers, which is achieved through the following technical solution.

[0016] Furthermore, the inner wall of the fixing sleeve is fixedly connected to a sliding rod corresponding to the fixing block, and the outer wall of the fixing block is provided with an insertion hole, in which the sliding rod is slidably connected.

[0017] Furthermore, a handle is uniformly fixed to the upper surface of the disk.

[0018] Furthermore, the lower surface of the climbing sleeve is symmetrically fixed with two arc-shaped elastic plates, and also includes a clamp.

[0041] S4: The installation device and the transformer body A are raised along the pole 11 by the lifting device. When they reach the specified height, the installation device is fixed by the components in the fixing sleeve 22.

[0042] Preferably, a reinforcing rod 13 is fixedly connected between the support rods 12.

[0043] Preferably, the bottom circumference of the fixing sleeve 22 is uniformly provided with fixing blocks 24, the upper surface of the fixing blocks 24 is inclined downward in the direction away from the center of the fixing sleeve 22, the inner wall of the fixing sleeve 22 is provided with internal threads 25, and also includes a disc 26. The outer wall of the disc 26 is fixedly connected with external threads 27. The disc 26 is engaged in the fixing sleeve 22 through the cooperation of external threads 27 and internal threads 25. The lower surface of the disc 26 is fixedly connected with an annular abutment block 28, and the lower surface of the abutment block 28 is adapted to the upper surface of the fixing block 24.

[0044] Preferably, the inner wall of the fixing sleeve 22 is fixedly connected to a slide rod 29 corresponding to the fixing block 24, and the outer wall of the fixing block 24 is provided with an insertion hole 210, in which the slide rod 29 is slidably connected.

[0045] Preferably, a handle 211 is uniformly fixed to the upper surface of the disc 26.

[0046] Preferably, the lower surface of the climbing sleeve 21 is symmetrically fixed with two arc-shaped elastic plates 212, and also includes a clamp 213. The clamp 213 is sleeved on the outside of the elastic plates 212. The clamp 213 is an open circle. The two ends of the clamp 213 are fixed with ear plates 214. The clamp 213 is made of elastic material. The two ear plates 214 are connected by bolts 215.

[0047] Preferably, the lifting device includes a traction device 31, a traction rope 32 driven by the traction device 31, a rope loop 33 fixed to the mounting plate 23, and a fixed pulley 34 rotatably connected to the support rod 12.

[0048] Preferably, the traction device 31 includes a base 311 and a motor 312. A transmission chamber 313 and a support plate 314 are fixedly connected to the upper surface of the base 311. Two gears 316 are rotatably connected in the transmission chamber 313 through symmetrical rotating shafts 315. The two gears 316 mesh with each other. The right end of each rotating shaft 315 is rotatably connected to the support plate 314. A winding roller 317 is fixedly connected to the rotating shaft 315 between the support plate 314 and the transmission chamber 313. One end of the traction rope 32 is fixedly connected to the winding roller 317. The motor 312 is fixedly connected to the base 311 and located on the left side of the transmission chamber 313. The output shaft of the motor 312 is connected to the front rotating shaft 315 through a coupling 318.

[0049] One specific embodiment of the present invention is as follows:

[0050] First, attach the climbing sleeve 21 and the fixing sleeve 22 to the bottom of the utility pole 11. Then, erect the utility pole 11, anchoring its bottom into the soil. Figure 2 and 3 As shown, in the initial position, the position of the disc 26 is adjusted so that the abutment block 28 contacts the top of the upper surface of the fixing block 24. At this time, the utility pole 11 passes through the climbing sleeve 21, the fixing sleeve 22 and the disc 26. The integrated structure of the climbing sleeve 21 and the fixing sleeve 22 can slide freely on the utility pole 11.

[0051] Then, the mounting plate 23 is welded and fixed between the climbing sleeves 21, and the transformer body A is fixed on the mounting plate 23. The transformer body A is installed on the ground, which facilitates position adjustment and debugging of the transformer body A, avoids the phenomenon of the transformer body A falling due to lifting, and also avoids the danger caused by installing heavy objects at high altitudes.

[0052] like Figure 7 As shown, after the transformer body A is fixed on the mounting plate 23, the traction rope 32 is unwound from the winding roller 317, and the free end of the traction rope 32 is guided by the fixed pulley 34 and tied to the rope ring 33.

[0053] like Figure 6As shown, the motor 312 drives the front shaft 315 and gear 316 to rotate, and the rear gear 316 and shaft 315 also rotate synchronously. The winding roller 317 fixed on the shaft 315 rotates synchronously. Since the two meshing gears 316 rotate in opposite directions, the two winding rollers 317 also rotate in opposite directions.

[0054] like Figure 7 As described above, when the two winding rollers 317 rotate in opposite directions, the two traction ropes 32 can be wound up synchronously, thereby lifting the installation device and the transformer body A.

[0055] When the designated position is reached, the handle 211 drives the disc 26 to rotate and descend, and the abutment block 28 descends synchronously. The abutment block 28 causes each fixing block 24 to move closer to the pole 11, thereby fixing the position of the fixing cylinder through the fixing block 24, that is, fixing the height of the installation device, and simultaneously fixing the position of the transformer body A.

[0056] The present invention also includes a clamp 213 for fixing, such as Figure 4 As shown, the clamp 213 is fitted over the two elastic plates 212, and the clamp 213 is contracted by the bolt 215, so that it can be further fixed.

[0057] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
