Description

Technical Field

[0001] This utility model belongs to the technical field of transformer dismantling equipment, and more specifically, it relates to a mechanism for separating the coil and upper silicon steel sheet of a transformer. Background Technology

[0002] With the intelligent and efficient development of the power industry, the number of scrap transformers has surged. Their standardized dismantling and high-value recycling have become key issues in the resource regeneration field, significantly contributing to alleviating metal resource conflicts and reducing pollution. Within scrap transformers, the copper coils contain copper resources with a purity exceeding 99%, and the professional recycling rate exceeds 95%, resulting in significant economic benefits. Silicon steel sheets, after processing, can be reused in the manufacture of power equipment cores, aligning with the trend of green development. However, currently, the separation of the core (copper coil and silicon steel sheet composite) after dismantling still relies on manual operation, presenting a prominent problem: First, this dismantling method is inefficient and cannot meet the needs of large-scale processing: because the overall volume of waste transformers (especially large industrial transformers) is large, the weight of their built-in cells can usually reach hundreds of kilograms or even several tons. When separating the copper coils from the silicon steel sheets, 2-3 operators need to work together to complete the task. A single separation operation generally takes more than 4 hours, and the operation efficiency is extremely low. It cannot match the capacity requirements of large-scale waste transformer recycling and processing, which seriously restricts the large-scale development of the resource recycling industry. Secondly, this disassembly method has high safety risks and is prone to causing work-related injuries to workers: during the manual disassembly and lifting of silicon steel sheets, the silicon steel sheets are prone to accidental shaking and falling off due to uneven force or unstable fixation. This may not only damage the separated parts, but also cause workers to be injured by falling parts. The safety factor of the operation is low and does not meet the safety management requirements of modern industrial production. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model relates to a coil and silicon steel sheet clamping and separating mechanism for a transformer. This addresses the issue that existing dismantling methods still primarily rely on manual labor. Due to the large size of transformers and the weight of their internal cells, separating the coil and silicon steel sheet from each scrap transformer requires 2-3 operators and takes over 4 hours, making it difficult to meet the capacity demands of large-scale recycling. Furthermore, manual dismantling has a low safety factor; during dismantling, the silicon steel sheet is prone to detaching due to shaking, potentially causing worker injuries.

[0004] In a first aspect, this utility model provides a coil and upper silicon steel sheet clamping and separating mechanism for a transformer, achieved by the following specific technical means: A coil and upper silicon steel sheet clamp separation mechanism for a transformer, comprising: The main frame has a sub-frame located at its lower inner side, and a control motor located at the upper outer side of the sub-frame. A placement platform is rotatably mounted on the sub-frame and is fixed to the shaft of the control motor. A movable stage is slidably mounted on a guide rail inside the main frame. A clamp on the side of the movable stage can clamp the transmission belt inside the guide rail. Movable arms are slidably mounted on both sides of a lifting platform at the lower end of the movable stage. A connecting plate inside the movable arm is slidably engaged with a controller at the lower end of the lifting platform. The connecting plate is threadedly connected to a screw inside the controller. A fixing plate is fixedly mounted inside the rear movable arm, and a fixing frame is mounted on the outer end of the front movable arm. The fixing plate and the fixing frame are arranged opposite to each other.

[0005] Furthermore, a conveyor belt is provided at the lower inner side of the main frame, and the conveyor belt is adjacent to the sub-frame; the guide rail is fixedly installed on the top of the main frame, and a transmission belt is provided inside the guide rail, which is controlled by a motor.

[0006] Furthermore, support blocks are equidistantly arranged at the top of the placement platform, and anti-slip grooves are provided on the top of the support blocks; clamping rods are slidably installed on both sides of the placement platform, and electric cylinders A are provided on both sides of the bottom of the placement platform, with the piston of the electric cylinder A fixedly connected to the clamping rods.

[0007] Furthermore, grippers are installed on both sides of the upper end of the moving platform, and an electric cylinder B is vertically installed on the inner side of the moving platform.

[0008] Furthermore, the lifting platform is fixed to the piston rod on the electric cylinder B, and guide rods are installed at both ends of the lifting platform. The guide rods are slidably engaged with the moving platform. Controllers are provided on both sides of the bottom of the lifting platform, and screws controlled by a motor are rotatably installed inside the controllers.

[0009] Furthermore, a connecting plate is provided on the upper inner side of the movable arm, a stop plate is provided on the inner side of the rear movable arm, and a clamp is installed on the bottom side of the movable arm. The clamps on the two sets of movable arms are arranged opposite each other.

[0010] Furthermore, a mounting plate is fixedly installed on the inner side of the front movable arm, and a top plate is installed on the mounting plate via an electric telescopic rod.

[0011] Furthermore, a clamping block is provided on the outside of the fixing plate, and an installation rod is provided on the outer end of the clamping block. The installation rod slides with the fixing plate, and a spring is sleeved on the outside of the installation rod. The two sides of the spring are in contact with the clamping block and the fixing plate respectively.

[0012] Furthermore, a double-ended lead screw controlled by a motor is rotatably mounted inside the fixed frame, and two sets of inserts are slidably mounted inside the fixed frame, the inserts being threadedly connected to the double-ended lead screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, the separation operation is achieved through an automated structure: the control motor can drive the placement platform to swing, so that the silicon steel sheet is loosened on the battery cell in advance, reducing the subsequent separation resistance; the controller drives the connecting plate through the screw, which drives the movable arm to move synchronously, without the need for manual force. Combined with the automatic movement of the moving table on the guide rail (driven by the transmission belt), the time of a single separation operation can be greatly shortened, eliminating the efficiency limitation of manual operation and effectively increasing the processing capacity per unit time. 2. In this device, the clamps on the fixed plate elastically abut against the silicon steel sheet via springs, maintaining the stability of the silicon steel sheet during hoisting and separation; the clamps on the movable arm can firmly abut against the silicon steel sheet, preventing it from swaying during the separation and hoisting process; the insert claws can overlap the abutment plate after passing through the battery cell, preventing the silicon steel sheet from falling off due to tilting of the insert claws during hoisting, fundamentally reducing the occurrence of work-related injuries such as silicon steel sheet impacts, and improving the operational safety factor. The entire separation process is completed through an automated structure, eliminating the need for direct manual contact with the heavy silicon steel sheet and copper coil, reducing the frequency of contact between operators and dangerous parts, and meeting the requirements of modern industrial safety management.

[0027] The specific usage and function of this embodiment are as follows: In this utility model, such as Figures 1 to 6As shown, the battery cells removed from the scrap transformer are placed on the top of the placement platform 2, which is rotatably mounted on the inner side of the main frame 1 and the auxiliary frame 101. The bottom of the battery cell contacts the support block 201 on the placement platform 2. Then, the electric cylinders A2021 on both sides of the bottom of the placement platform 2 are activated. The pistons of the electric cylinders A2021 drive the clamping rod 202 to move towards the battery cell until the clamping rod 202 clamps and fixes the battery cell. Next, the drive belt 1031, controlled by a motor, is activated within the top guide rail 103 of the main frame 1. Simultaneously, the clamp 301 on the side of the moving platform 3 clamps and fixes the drive belt 1031. The drive belt 1031 drives the moving platform 3 to slide along the guide rail 103. The moving platform 3 is moved to a position directly above the placement platform 2. The connection between the coil and silicon steel sheet and the battery cell is severed using appropriate equipment. Then, the electric cylinder B302, vertically mounted inside the moving platform 3, is activated. The piston rod of the electric cylinder B302 pushes the lower, fixed lifting platform 303 downwards. The guide rods 3031 at both ends of the lifting platform 303 slide along the moving platform 3 to maintain stable lifting until the movable arms 4, slidably mounted on both sides of the lifting platform 303, move to the corresponding height of the battery cell. Subsequently, the controllers 3032 on both sides of the bottom of the lifting platform 303 are activated. The screw inside the controller 3032, controlled by a motor, rotates, driving the connecting plate 401, threadedly connected to the screw, to move. The connecting plate 401 drives the movable arm 4 to slide along the lifting platform 303, causing the fixed frame 6 installed on the outer end of the front movable arm 4 and the fixed plate 5 fixed inside the rear movable arm 4 to move closer to the battery cell. At the same time, the double-headed screw 601 inside the fixed frame 6, controlled by a motor, is activated. The double-headed screw 601 drives two sets of slidingly installed claws 602 to adjust their spacing, so that the claws 602 pass through the battery cell and engage with the abutment plate 402 on the rear movable arm 4. Meanwhile, the clamping block 501, which is slidably installed on the outside of the fixed plate 5 via the mounting rod 502, abuts against the silicon steel sheet under the elastic force of the spring 503. The top plate 4 on the front movable arm 4 is installed via the mounting plate 404. 041 Press the silicon steel sheet firmly; then start the electric cylinder B302 again to move the lifting platform 303 upward. The inserter 602 drives the silicon steel sheet upward to separate from the battery cell. Use the moving platform to send it to the corresponding place for collection. After disassembling the silicon steel sheet, move the lifting platform 303 to the previous position. At the same time, control the movable arm 4 to continue moving so that the clamping plate 403 on the movable arm 4 clamps the copper coil. The lifting platform 303 continues to rise to completely separate the copper coil from the battery cell. After separation, release the clamping rod 202 and transport the remaining parts outward through the conveyor belt 102 to complete a single disassembly and separation operation. Repeat the above steps to disassemble and separate the next battery cell.
