[0022] Please see Figure 1 and Figure 4 This utility model provides a technical solution: a forced oil transformer oil pipe assembly structure, including a winding 1, a core column 2 disposed in the middle of the winding 1, a clamping mechanism 3 disposed on the outer side wall of the winding 1, lifting arms 4 movably connected to both sides of the lower end of the winding 1, pads 5 fixedly connected around the lower end of the winding 1, an oil pipe body 6 fixedly connected to the lower end of the pads 5, a fixing mechanism 7 detachably connected to the bottom of the oil pipe body 6, a clamp 8 detachably connected to the inner side of the fixing mechanism 7, and the clamping mechanism 3 including a slot 31, the outer wall of the slot 31 being connected to... The bottom wall of the winding 1 is embedded and connected. The inner wall of the slot 31 is provided with a plug 32. The upper end of the plug 32 is provided with a movable frame 33. The two sides of the movable frame 33 are fixedly connected with connecting ear plates 34. The two sides of the movable frame 33 are embedded and connected with limit grooves 35. The movable frame 33 is detachably connected with a fixed frame 36 on one side. The two sides of the fixed frame 36 are fixedly connected with limit plates 37. The inner wall of the connecting ear plate 34 is threaded with bolts 38. The outer wall of the core column 2 is inserted into the inner wall of the winding 1. The inner side wall of the clamping mechanism 3 is detachably connected to the outer side wall of the winding 1.

[0023] The hoisting equipment boom 4 lifts the winding 1 and wraps it around the core column 2. The boom 4 is then removed. The pad 5, the oil guide pipe body 6, and the fixing seat 71 are pre-assembled into a whole and installed on the clamp 8 with fasteners 73. The winding 1 is then wrapped around the core column 2. The boom 4 is then removed, and the oil guide pipe is reassembled. This process does not affect the removal of the boom 4 and allows for the rapid pre-assembly of the pad 5, the oil guide pipe body 6, and the fixing seat 71. The fasteners 73 are then installed on the clamp 8, completing the installation of the oil guide pipe body 6. The bottom of the oil guide pipe body 6 is connected to the transformer through the fixing mechanism 7, ensuring the stability of the oil guide pipe during transformer operation. The fixing mechanism 7 is detachable, facilitating maintenance or replacement when needed. The clamp 8 is connected to the fixing seat 71 through the fasteners 73, allowing the clamp 8 to be adjusted in position as needed to accommodate oil guide pipes of different sizes.

[0024] Please see Figure 2 In order to quickly clamp and fix the winding 1 on the iron core column 2, the inner wall of the slot 31 is engaged with the outer wall of the plug 32, the upper end of the plug 32 is fixedly connected to the lower end of the movable frame 33, and the movable frame 33 and the fixed frame 36 are both semi-arc structures.

[0025] The embedded connection between the limiting groove 35 and the movable frame 33 ensures the precise position of the movable frame 33 during the winding 1 assembly process, preventing it from shifting during operation. The fixed connection between the limiting plate 37 and the fixed frame 36 further enhances the stability of the clamping mechanism 3, ensuring the reliability of the entire assembly structure. Through this setting, the forced oil transformer oil pipe assembly structure not only improves the assembly efficiency but also enhances the safety and stability of the transformer during operation.

[0026] Please see Figure 3 In order to quickly fix the oil guide tube body 6 onto the clamp 8, the fixing mechanism 7 includes a fixing seat 71. The inner wall of the fixing seat 71 is detachably connected to the outer wall of the oil guide tube body 6. The inner wall of the fixing seat 71 is provided with a rubber pad 72. Fasteners 73 are provided on both sides of the fixing seat 71. A washer 74 is sleeved on one end of the outer wall of the fastener 73. Fastening holes 75 are opened through both sides of the fixing seat 71. The inner wall of the fixing seat 71 is bonded to the outer wall of the rubber pad 72. The two sides of the fixing seat 71 are threaded to the outer wall of the fastener 73. The fastener 73 passes through the fastening holes 75 on both sides of the fixing seat 71 and extends into the clamp 8.

[0027] The rubber pad 72 provides additional cushioning to reduce vibration and impact on the oil guide tube body 6 during assembly, thereby protecting the oil guide tube body 6 from damage. The other end of the fastener 73 is threaded to the inner wall of the clamp 8. By rotating the fastener 73, the oil guide tube body 6 can be firmly fixed. The outer wall of the fastener 73 is fitted with a washer 74, which not only increases the friction between the fastener 73 and the fixing seat 71 to prevent the fastener 73 from loosening, but also protects the fastener 73 from corrosion. The entire fixing mechanism 7 ensures that the oil guide tube body 6 remains stable during transformer operation, avoiding failures caused by vibration or displacement.

[0028] Working principle: First, the winding 1 is lifted by the hoisting equipment boom 4 and placed on the core column 2. The boom 4 is then removed. The pad 5, oil guide pipe body 6, and fixing seat 71 are pre-assembled into a whole and installed on the clamp 8 with fasteners 73. The winding 1 is then placed on the core column 2. The boom 4 is removed again, and the oil guide pipe is then assembled. This process does not affect the removal of the boom 4 and allows for the rapid pre-assembly of the pad 5, oil guide pipe body 6, and fixing seat 71. The fasteners 73 are then installed on the clamp 8, completing the installation of the oil guide pipe body 6. The bottom of the oil guide pipe body 6 is connected to the transformer via a fixing mechanism 7, ensuring the stability of the oil guide pipe during transformer operation. The fixing mechanism 7 is designed to be detachable, facilitating maintenance or replacement when needed. The clamp 8 is connected to the fixed base 71 via fastener 73, allowing the clamp 8 to be adjusted in position as needed to accommodate oil pipes of different sizes. The embedded connection between the limiting groove 35 and the movable frame 33 ensures the precise position of the movable frame 33 during the winding 1 assembly process, preventing displacement during operation. The fixed connection between the limiting plate 37 and the fixed frame 36 further enhances the stability of the clamping mechanism 3, ensuring the reliability of the entire assembly structure. Through this design, the forced oil transformer oil pipe assembly structure not only improves assembly efficiency but also enhances the safety and stability of the transformer during operation.

[0029] The rubber pad 72 provides additional cushioning to reduce vibration and impact on the oil guide pipe body 6 during assembly, thereby protecting it from damage. The other end of the fastener 73 is threaded to the inner wall of the clamp 8. By rotating the fastener 73, the oil guide pipe body 6 can be firmly fixed. The outer wall of the fastener 73 is fitted with a washer 74, which not only increases the friction between the fastener 73 and the fixing seat 71, preventing the fastener 73 from loosening, but also protects the fastener 73 from corrosion. The entire fixing mechanism 7 ensures that the oil guide pipe body 6 remains stable during transformer operation, avoiding failures caused by vibration or displacement.
