Description

Technical Field

[0001] This utility model belongs to the technical field of transformer handling equipment, and more specifically, it relates to a transformer cell handling mechanism. Background Technology

[0002] In the field of power equipment manufacturing, maintenance and recycling, transformers are core power equipment. The disassembly and assembly of their internal battery cells (usually composed of iron core and winding assemblies) is a key technical link to ensure equipment performance stability and realize resource recycling. As the core functional component for energy conversion, the battery cells of transformers need to be safely and efficiently removed from the main structure of the transformer during equipment maintenance, technical upgrades or scrapping and recycling. In the process of disassembling and recycling transformers, the separation of the transformer battery cells from the lifting plate must be completed first. After separation, the battery cells need to be transported from the separation station to a special battery cell disassembly station for subsequent disassembly processing using special equipment.

[0003] Currently, the handling of transformer cells still mainly relies on manual operation. After dismantling, manual handling is required to separate and move the cells from the transformer's foundation components. This traditional operation mode has significant technical drawbacks: On the one hand, since transformer cells are usually large in size and weight, manual handling requires at least 2-4 operators to work together, resulting in high labor costs. In addition, the cells are usually heavy and large, and manual handling is prone to damage due to improper operation. At the same time, there are problems of high labor intensity and low work efficiency for operators, which makes it difficult to meet the high-efficiency operation requirements of modern production lines. On the other hand, uneven force during dismantling and handling can easily cause quality problems such as deformation or damage to the battery cell or transformer foundation parts due to uneven force during manual operation. This directly affects the equipment maintenance and reuse rate or the recycling value of materials. Especially for large transformer cells, if operational errors occur during manual handling (such as tool slippage or lack of coordination between personnel), the battery cell may fall accidentally, which may not only damage the equipment but also cause personal injury such as squeezing or crushing to the operators, which does not meet the technical specifications for safe production. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a transformer cell handling mechanism, which solves the problem that the dismantling of transformer cells mainly relies on manual labor. After dismantling, the cells need to be moved from the parts by manual handling. This method is not only labor-intensive and inefficient, but also prone to deformation and damage to the cells or transformer parts due to uneven force during dismantling. Especially for large transformer cells, manual handling poses a safety hazard of the cells falling off.

[0005] In a first aspect, this utility model provides a transformer cell handling mechanism, achieved by the following specific technical means: A transformer cell handling mechanism includes: a cage frame and a support frame. The cage frame is a metal structure, and the support frame is located inside the cage frame. The support frame is a metal structure of the same material as the cage frame. A carrier plate is movably mounted on the support frame. A mating block A on the side end of the carrier plate slides into a guide rail A on the support frame, and a fixing block inside the carrier plate is threadedly connected to a control screw inside the support frame. A sliding frame is movably mounted on a fixing frame at the upper end inside the cage frame. A mating block B on the sliding frame slides into a guide rail B at the outer end of the fixing frame, and a transmission belt inside the fixing frame passes through fixing clamps on both sides of the sliding frame, allowing the transmission belt to be clamped by the fixing clamps. Two sets of side arms are slidably mounted on a lifting frame at the lower end of the sliding frame. A mating block C inside the side arm slides into a guide rail C at the side end of the lifting frame, and a linkage plate inside the side arm slides into a drive box at the side end of the lifting frame, with the linkage plate threadedly connected to a screw in the drive box.

[0006] Furthermore, guide rails A are fixedly installed on both sides of the upper end of the support frame, and a control screw connected to the motor is rotatably installed at the middle position of the upper end of the support frame.

[0007] Furthermore, a fixing frame is fixedly installed at the middle position of the upper end of the cage frame, and a transmission belt driven by a motor is provided at the middle position of the fixing frame, and guide rails B are fixedly installed on both sides of the bottom of the fixing frame.

[0008] Furthermore, mating blocks A are symmetrically arranged on both sides of the bottom of the carrier plate, and a fixing block is arranged in the middle position inside the carrier plate.

[0009] Furthermore, clamping blocks are slidably installed on both sides of the carrier plate, and two sets of control cylinders A are provided at the bottom of the carrier plate, with the piston rods on the control cylinders A connected and fixed to the clamping blocks.

[0010] Furthermore, fixing clamps are fixedly installed at both ends of the sliding frame, and mating blocks B are provided on both sides of the top of the sliding frame, and a control cylinder B is provided at the lower end of the interior of the sliding frame.

[0011] Furthermore, a lifting frame is provided below the sliding frame. The lifting frame is fixed to the piston rod at the bottom of the control cylinder B, and uprights are fixedly installed on both sides of the lifting frame. The uprights are slidably engaged with the sliding frame. Drive boxes are fixedly installed at the lower ends of both sides of the lifting frame. A lead screw connecting to the motor is rotatably installed inside the drive box. Guide rails C are installed on both sides of the lifting frame.

[0012] Furthermore, a mating block C is provided at the inner top of the side arm, a linkage plate is provided at the inner upper end of the side arm, and a contact plate is provided at the bottom side end of the side arm. A guide rod is fixedly installed on the contact plate, and a buffer spring is fitted on the guide rod. The buffer spring acts on the contact plate and the side arm on both sides.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, the coordinated operation of structures such as cages, support frames, carrier plates, sliding frames, and side arms enables mechanized operation of key operations such as transfer and clamping during transformer core removal. Compared with the traditional manual handling mode, it eliminates the need for manual labor to complete the separation, transfer, and positioning of the cores. The time for a single handling operation can be reduced to 5-8 minutes, and 2 to 5 units can be dismantled per hour. Only one operator is required to monitor the equipment, reducing labor costs by more than 75% and increasing work efficiency by more than 3 times. It is fully compatible with the cycle requirements of modern production lines and significantly reduces the labor intensity of operators. At the same time, precise control is achieved through components such as motor-driven control screws, transmission belts, and drive boxes, effectively improving the overall efficiency of the dismantling operation and meeting the needs of large-scale production and recycling.

[0014] 2. In this device, considering the large size and weight of the transformer cores, the mechanism achieves stable gripping and transfer of the cores through the clamping structure of the side arm and the vertical movement function of the lifting frame. This avoids the problem of accidental dropping of the cores during manual handling. At the same time, the buffer spring on the contact plate can prevent the cores from being damaged due to excessive clamping force, further improving operational safety and providing reliable protection for the personal safety of operators. In addition, the movement of the carrier plate, sliding frame, and side arm is guided by guide rails, with precise movement trajectory, preventing scratches with the transformer foundation parts, effectively protecting the foundation parts for reuse, and reducing equipment maintenance and recycling costs by more than 40%.

[0028] The specific usage and function of this embodiment are as follows: In this utility model, such as Figures 1 to 6As shown, after the transformer core is initially disassembled on the carrier plate 2 at the previous workstation, the control cylinder A204 is activated, causing the piston rod of the control cylinder A204 to push the clamping block 203 to slide along the carrier plate 2 until the clamping block 203 is released from the transformer component; then the control screw 1012 connected to the motor on the support frame 101 is activated, and the control screw 1012 is threadedly driven with the fixing block 202 in the carrier plate 2, driving the carrier plate 2 to move back and forth along the guide rail A1011 on the support frame 101 through the mating block A201 at the side end. The drive belt 1021, driven by a motor, inside the fixed frame 102 is activated. The drive belt 1021 drives the sliding frame 3 to move via the fixed clamps 301 on both sides of the sliding frame 3. The sliding frame 3 slides left and right along the guide rail B1022 at the outer end of the fixed frame 102 via the mating block B3011 at the top, so that the lifting frame 303 at the lower end of the sliding frame 3 is aligned with the battery cell position. The control cylinder B302 inside the sliding frame 3 is activated. The piston rod at the bottom of the control cylinder B302 pushes the lifting frame 303 to move vertically. The lifting frame 303 moves vertically via... The upright pole 3031 slides smoothly with the sliding frame 3 to achieve stable lifting and lowering until the side arm 4 descends to the height corresponding to the battery cell. Then, the lead screws connected to the motors in the drive boxes 3032 on both sides of the lifting frame 303 are activated. The lead screws are threadedly driven by the linkage plate 402 in the side arm 4, causing the side arm 4 to slide along the guide rail C3033 on the side end of the lifting frame 303 through the mating block C401. This brings the two sets of side arms 4 closer together, and the contact plate 403 at the bottom of the side arm 4 contacts both sides of the battery cell. The guide rod 4031 on the contact plate 403 moves accordingly. The clamping action compresses the buffer spring to achieve elastic clamping of the battery cell. After clamping, the lifting frame 303 is raised again by the control cylinder B302 to lift the battery cell from the side station. Then, it is driven by the transmission belt 1021 and moved along the fixed frame 102 to transfer the battery cell to the carrier plate 2 of the next processing area. Finally, the screw in the drive box 3032 is activated in reverse to release the battery cell by the side arm 4, completing the entire handling operation process, so that the battery cell can be disassembled in the next station.
