[0024] Traditional hoisting devices typically use simple three-sling hoisting equipment. However, these devices are poorly compatible with the triangular structure on top of the three-phase three-dimensional wound core distribution transformer. During hoisting, the direction of force on the hoisting ropes is not entirely consistent with the direction of gravity of the transformer, which can easily lead to uneven force distribution on the hoisting device, causing the transformer to sway and increasing safety risks during the hoisting process.

[0025] This utility model proposes a hoisting device for the core of a three-phase three-dimensional wound iron core distribution transformer, including a hoist 10 and three hoisting ropes 20. The hoist 10 includes a frame, a column 12 and an adjusting plate 13. The frame includes three surrounding plates 11, which are connected end to end and form a triangle. The column 12 extends vertically and is set between the three surrounding plates 11. The connection between the column 12 and any two surrounding plates 11 is connected by an adjusting plate 13. Each adjusting plate 13 has multiple grooves 131 spaced apart along the extension direction of the adjusting plate 13. The three hoisting ropes 20 are respectively set corresponding to the three adjusting plates 13. The top of each hoisting rope 20 is suspended in any groove 131 on the corresponding adjusting plate 13, and the bottom of each hoisting rope 20 is equipped with a hook 21.

[0026] Please see Figure 1 Three enclosure panels 11 surround each other to form a triangular frame. Any two enclosure panels 11 are connected to form a connecting seam. The column 12 and three adjusting plates 13 are located between the three enclosure panels 11. Each connecting seam is connected to an adjusting plate 13 between itself and the column 12. Three suspension ropes 20 are respectively suspended on the corresponding adjusting plates 13, so that the three suspension ropes 20 are triangularly distributed. The bottom end of each suspension rope 20 is equipped with a hook 21, and the three hooks 21 are respectively hooked to the top triangle of the three-phase three-dimensional wound iron core distribution transformer body. Multiple grooves 131 on each adjusting plate 13 are spaced apart along the extension direction of the adjusting plate 13. By adjusting the suspension ropes 20 to be suspended in different grooves 131, the distance between the suspension ropes 20 and the column 12 can be adjusted, so that the three suspension ropes 20 are closer or farther apart to adapt to the different sizes of the three-phase three-dimensional wound iron core distribution transformer body.

[0027] The three-phase three-dimensional wound core distribution transformer body hoisting device proposed in this utility model consists of three surrounding plates 11 forming a triangular frame. A column 12 is set inside the frame, and an adjusting plate 13 is set between the column 12 and any two surrounding plates 11. A groove 131 is opened on each adjusting plate 13, and three lifting ropes 20 are respectively suspended in the grooves 131 on the corresponding adjusting plates 13. The three hooks 21 at the bottom of the three lifting ropes 20 are respectively hooked to the top triangle of the three-phase three-dimensional wound core distribution transformer body to realize the hoisting of the three-phase three-dimensional wound core distribution transformer body. Multiple grooves 131 on each adjusting plate 13 are spaced apart along the extension direction of the adjusting plate 13, allowing the lifting ropes 20 to be suspended in different grooves 131 on the corresponding adjusting plates 13. This enables flexible adjustment of the distance between the lifting ropes 20 and the column 12, allowing the three lifting ropes 20 to move closer or further apart to accommodate three-phase three-dimensional wound core distribution transformer bodies of different sizes, effectively improving the flexibility and adaptability of the lifting device. During the lifting process, each lifting rope 20 remains vertical, and the direction of force on the lifting ropes 20 is consistent with the direction of gravity of the three-phase three-dimensional wound core distribution transformer body, thereby reducing the swaying of the three-phase three-dimensional wound core distribution transformer body during lifting and reducing safety risks during the lifting process.

[0028] In one embodiment, the three enclosure panels 11 are of the same length and together form an equilateral triangle frame, the column 12 passes through the center of gravity of the frame, and the three adjustment plates 13 are respectively located on the three angle bisectors of the frame.

[0029] It should be noted that the three enclosure plates 11 are of the same length and together form an equilateral triangle frame, making the frame structure more symmetrical and stable. The three adjustment plates 13 are located on the three angle bisectors respectively. The three angle bisectors of the frame intersect at the column 12, so that the column 12 passes through the center of gravity of the frame, ensuring the balance of the center of gravity of the entire device, making the force even during hoisting, and further enhancing the stability of the hoisting device.

[0030] In one embodiment, each adjusting plate 13 is connected to the bottom of the column 12, and a connecting rod 14 is connected between the top of the column 12 and the connection point of any two surrounding plates 11.

[0031] Please continue reading. Figure 1A connecting seam is formed at the connection of any two enclosure plates 11. The width direction of the adjusting plate 13 is consistent with the extension direction of the connecting seam. The connecting rod 14 is connected to the end of the connecting seam, so that the connecting rod 14 is above the adjusting plate 13. The connecting rod 14 and the adjusting plate 13 are staggered and located in the same horizontal plane. The connecting rod 14, the adjusting plate 13 and the column 12 together form a triangular structure. The connecting rod 14 plays a reinforcing role between the column 12 and the enclosure plate 11, which can effectively prevent structural deformation caused by lateral force or vibration generated during hoisting, thereby improving the vibration resistance and stability of the hoisting device.

[0032] In one embodiment, a rope loop 22 is provided at the top of the suspension rope 20. The rope loop 22 is sleeved on the corresponding adjustment plate 13 and snapped into any groove 131.

[0033] It can be explained that the rope loop 22 is sleeved outside the adjusting plate 13, and the top of the rope loop 22 is engaged in the groove 131. The suspension rope 20 can be fixed by putting the rope loop 22 into the adjusting plate 13 and engaging the corresponding groove 131. The rope loop 22 and the suspension rope 20 can be lifted to disengage from the groove 131. This not only facilitates quick adjustment of the position of the suspension rope 20, but also facilitates the disassembly and replacement of the suspension rope 20.

[0034] In one embodiment, the groove wall of the groove 131 is vertically arranged, and the width of the groove 131 is the same as the diameter of the rope loop 22.

[0035] Furthermore, the groove wall of the groove 131 is vertically arranged, so that when the rope loop 22 is engaged in the groove 131, it can be stably fixed in the vertical direction, preventing the rope loop 22 from being laterally displaced or slipped due to external forces during hoisting, and reducing the shaking or instability caused by the loosening of the rope loop 22 during hoisting, thereby reducing safety hazards during hoisting.

[0036] In one embodiment, a reinforcing column 15 is connected between the center of the column 12 and each enclosure panel 11.

[0037] It should be noted that three reinforcing columns 15 are respectively provided between the three enclosure panels 11 and the uprights 12. Each reinforcing column 15 is located at the shortest distance between the uprights 12 and each enclosure panel 11, so that the uprights 12 are connected to each enclosure panel 11 and the uprights 12 are fixed to the frame, which further improves the deformation resistance of the entire frame, thereby further improving the safety and reliability of hoisting.

[0038] In one embodiment, the reinforcing column 15 is a hollow alloy steel pipe, and the reinforcing column 15 is welded to the surrounding plate 11.

[0039] Furthermore, the reinforcing column 15 is made of hollow alloy steel pipe, which significantly reduces the structural weight of the reinforcing column 15 while ensuring sufficient strength, thereby improving the lightweight performance of the hoisting device. The reinforcing column 15 and the surrounding plate 11 are connected by welding, achieving a firm connection between the reinforcing column 15 and the surrounding plate 11. This allows the load on the surrounding plate 11 to be transferred more evenly to the column 12, avoiding local stress concentration, and thus further improving the internal structural stability of the hoisting device.

[0040] In one embodiment, a lifting ring 121 is provided at the top of the column 12.

[0041] It can be explained that when hoisting the body of the three-phase three-dimensional wound core distribution transformer, the hoisting device is set between the crane and the body of the three-phase three-dimensional wound core distribution transformer to ensure that the gravity load of the body of the three-phase three-dimensional wound core distribution transformer is stably transferred to the crane. A lifting ring 121 is set at the top of the column 12 to facilitate the crane to lift the hoisting device and the body of the three-phase three-dimensional wound core distribution transformer through the lifting ring 121.

[0042] In one embodiment, the hook 21 is a C-shaped hook 21.

[0043] Understandably, during hoisting, the open end of the C-shaped hook 21 can be quickly fitted onto the lifting ring 121 or other connecting parts on top of the three-phase three-dimensional wound core distribution transformer, thereby significantly improving hoisting efficiency. Simultaneously, the inner surface of the C-shaped hook 21 is optimized to ensure a tight fit with the lifting ring 121 or connecting parts, guaranteeing a secure and reliable connection between the hook 21 and the distribution transformer during hoisting, thus avoiding safety hazards caused by loose connections.

[0044] In one embodiment, a rubber pad is wound around the hook 21.

[0045] Furthermore, the rubber pad is placed between the hook 21 and the lifting ring 121 or other connecting parts at the top of the three-phase three-dimensional wound iron core distribution transformer. This effectively increases the friction between the hook 21 and the lifting ring 121 or other connecting parts at the top of the three-phase three-dimensional wound iron core distribution transformer, preventing relative slippage between the hook 21 and the lifting part due to vibration or shaking during the lifting process, thus further improving the safety and reliability of the lifting operation.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
