Technical Field
[0001] This utility model relates to the field of dismantling technology for waste power equipment, and in particular to an automatic centering and positioning device for transformers. Background Technology
[0002] Against the backdrop of accelerated smart grid construction and increasingly sophisticated requirements for power equipment installation, the installation accuracy of transformers, as core equipment in power transmission systems, directly impacts the stability and security of the power grid. Traditional manual installation methods, limited by measurement errors and operational efficiency, struggle to meet the dual demands of modern power engineering for transformer positioning with "millimeter-level accuracy" and "rapid deployment." The automatic transformer centering and positioning device has emerged to address this need. Integrating automated control, precision sensing, and mechanical transmission technologies, it has become a key component for improving the quality and efficiency of power equipment installation.
[0003] Existing transformer positioning devices mostly adopt basic mechanical transmission and simple electrical control. Their working principle is usually as follows: the positioning benchmark is measured manually in advance, and then the motor drives the lead screw or slide rail mechanism to move the bearing platform horizontally; the vertical direction is achieved by hydraulic or pneumatic adjustment; in the fixing link, a single-sided or asymmetrical clamping structure is commonly used, with a motor driving a single clamping arm to extend and gradually squeeze the transformer to the predetermined position.
[0004] In existing technologies, traditional devices lack adaptive adjustment capabilities. When dealing with transformers of different sizes, it is necessary to frequently replace or manually adjust the clamping components, resulting in poor equipment versatility. Therefore, an automatic transformer centering and positioning device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic centering and positioning device for transformers, which aims to improve the problem of low clamping efficiency in some existing devices.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic centering and positioning device for a transformer includes two support columns. A transverse support bar is fixedly connected to the top of each support column. A horizontal moving mechanism is provided outside each support column. A sliding plate is fixedly connected to the outside of the horizontal moving mechanism. A lifting mechanism is provided at the bottom of the sliding plate. A connecting block is fixedly connected to the bottom of the lifting mechanism. A fixing mechanism is provided at the bottom of the connecting block. The fixing mechanism includes a housing. The outside of the housing is fixedly connected to the bottom of the connecting block.

A fixing plate is fixedly connected to the outside of the housing. A braking assembly for driving is fixedly connected to the outside of the fixing plate.
[0008] As a further description of the above technical solution:
[0009] The horizontal moving mechanism includes a second motor, which is fixedly connected to the outside of the support column. A transmission disc is fixedly connected to the drive end of the second motor, and a transmission shaft is fixedly connected to the outside of the transmission disc.
[0010] As a further description of the above technical solution:
[0011] The inner sides of the transmission ring are slidably connected to the outside of the limiting post, and a fixed bracket is fixedly connected to the bottom of the transmission ring. The outside of the fixed bracket is slidably connected to the bottom of the outer shell.
[0012] As a further description of the above technical solution:
[0013] The braking assembly includes a motor, which is externally fixedly connected to the outside of the fixed plate, and a pulley is fixedly connected to the drive end of the motor.
[0014] As a further description of the above technical solution:
[0015] One end of the threaded rod is fixedly connected to a second pulley, and a transmission belt is sleeved on the outside of the second pulley and the first pulley;
[0016] As a further description of the above technical solution:
[0017] The support column is fixedly connected to a fixed shaft, and the fixed shaft is rotatably connected to a transmission connecting plate. The internal groove of the transmission connecting plate is slidably connected to the outside of the transmission shaft.

[0021] The lifting mechanism includes a sliding block, the top of which is slidably connected to the bottom groove of the sliding plate, and a cylinder is fixedly connected to the bottom of the sliding block, the driving end of which is fixedly connected to the top of the connecting block.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the fixed bracket can quickly clamp and release the transformer by means of a motor, a belt pulley drive and a threaded rod. The limit post restricts the rotation of the transmission ring to ensure that it moves only along the axial direction, making the clamping process stable and without deviation. The belt drive structure can buffer the impact force of the motor starting and reduce mechanical wear. The bidirectional drive function supports forward and reverse operation, and the fixed bracket spacing can be flexibly adjusted according to the needs, which effectively improves the efficiency and safety of transformer positioning and installation.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic centering and positioning device for transformers, comprising two support columns 1. The support columns 1 are used to stabilize the main body of the device, ensuring that the device will not shake or shift during the positioning process, providing a stable foundation for the precise operation of subsequent mechanisms. A transverse support bar 2 is fixedly connected to the top of the two support columns 1. The transverse support bar 2 is used to enhance the overall rigidity of the device and provide a track and guide for the horizontal movement of the sliding plate 3. A horizontal moving mechanism 7 is provided on the outside of the support columns 1. The horizontal moving mechanism 7 is used to adjust the position of the device in the horizontal direction, converting the motor power into the linear motion of the sliding plate 3 through mechanical transmission. To adjust the position of the transformer on the horizontal plane, a sliding plate 3 is fixedly connected to the outside of the horizontal moving mechanism 7. The sliding plate 3 can slide horizontally along the groove of the transverse support bar 2, driving the lower mechanism and the transformer to move synchronously. A lifting mechanism 4 is provided at the bottom of the sliding plate 3. The lifting mechanism 4 is used to adjust the height of the transformer in the vertical direction to adapt to different installation height requirements. At the same time, it can fine-tune the levelness of the transformer. A connecting block 5 is fixedly connected to the bottom of the lifting mechanism 4. A fixing mechanism 6 is provided at the bottom of the connecting block 5. The fixing mechanism 6 is used to clamp and fix the transformer to keep it stable during positioning and installation and prevent displacement.
[0033] The fixing mechanism 6 includes a housing 61, which provides installation space and protection for the internal threaded rod 62 and limiting posts 63, preventing external debris from entering and affecting the operation of the mechanism. The outer shell 61 is fixedly connected to the bottom of the connecting block 5. The threaded rod 62 is rotatably connected inside the housing 61. The threaded rod 62 converts the rotational power of the motor into the axial movement of the transmission ring 64 through its own rotational movement, thereby controlling the extension and retraction of the fixing bracket 66. Two limiting posts 63 are fixedly connected inside the housing 61. The limiting posts 63 are used to restrict the rotation of the transmission ring 64, ensuring that the transmission ring 64 can only move along the axial direction of the threaded rod 62, making the movement trajectory of the fixing bracket 66 more stable. The threaded rod 62 is externally threadedly connected to the transmission ring 64, which is used to cooperate with the threaded rod 62 and move axially when the threaded rod 62 rotates, thereby... The fixed bracket 66 extends or retracts to the bottom of the outer shell 61. A fixed plate 65 is fixedly connected to the outside of the outer shell 61. The fixed plate 65 is used to install the braking assembly 67 and provides a fixed support point for the motor 671. The braking assembly 67 is fixedly connected to the outside of the fixed plate 65 for driving. The braking assembly 67 provides a power source for the rotation of the threaded rod 62. Through motor drive and belt transmission, the forward and reverse rotation of the threaded rod 62 is realized, controlling the clamping and loosening action of the fixed bracket 66. The inner sides of the transmission ring 64 are slidably connected to the outside of the limiting post 63. The bottom of the transmission ring 64 is fixedly connected to the fixed bracket 66. The fixed bracket 66 is used to directly contact the transformer. By extending or retracting, it realizes the clamping and loosening of the transformer. It is the execution component of the fixing mechanism 6. The outside of the fixed bracket 66 is slidably connected to the bottom of the outer shell 61.
[0034] The braking assembly 67 includes a motor 671, which drives a pulley 672 to rotate, thereby rotating a threaded rod 62. The motor 671 is externally fixed to the outside of the fixed plate 65. The drive end of the motor 671 is fixedly connected to the pulley 672, which rotates synchronously with the drive end of the motor 671. Power is transmitted to a pulley 674 via a transmission belt 673. One end of the threaded rod 62 is fixedly connected to the pulley 674, which is connected to the pulley 672 via the transmission belt 673. The pulley 674 receives the power transmitted from the pulley 672 and drives the threaded rod 62 to rotate. The transmission belt 673 is sleeved on the outside of the pulley 674 and the pulley 672. The transmission belt 673 can buffer the impact force during motor startup and operation, reducing mechanical wear.
[0035] Reference Figure 1 , Figure 2 and Figure 4The horizontal moving mechanism 7 includes a second motor 71, which provides power to the mechanism. The second motor 71 drives the transmission disk 72 to rotate by outputting rotational power, thereby realizing the horizontal movement of the sliding plate 3. The second motor 71 is externally fixedly connected to the support column 1. The drive end of the second motor 71 is fixedly connected to the transmission disk 72. The transmission disk 72 rotates synchronously with the drive end of the second motor 71, converting the rotational motion of the motor into the circular motion of the transmission shaft 74, providing power for subsequent transmission. The transmission disk 72 is externally fixedly connected to the transmission shaft 74. 74, the transmission shaft 74 is used to convert the circular motion of the transmission disc 72 into the swing motion of the transmission connecting plate 75, and is a key transmission component for realizing horizontal movement. The support column 1 is fixedly connected to the outside of the fixed shaft 73, and the transmission connecting plate 75 is rotatably connected to the outside of the fixed shaft 73. The transmission connecting plate 75 is used to convert the circular motion of the transmission shaft 74 into the linear motion of the transmission shaft 76 by swinging on the fixed shaft 73, thereby driving the sliding plate 3 to move horizontally. The inner groove of the transmission connecting plate 75 is slidably connected to the outside of the transmission shaft 74.
[0036] The transverse support bar 2 has a groove inside, and a second sliding block 77 is slidably connected inside the groove of the sliding plate 3. The second sliding block 77 provides guidance and support for the horizontal movement of the sliding plate 3, allowing the sliding plate 3 to slide smoothly along the groove of the transverse support bar 2 and ensuring the accuracy of horizontal movement. A second transmission shaft 76 is fixedly connected to the outside of the second sliding block 77. The second transmission shaft 76 is used to convert the swing motion of the transmission connecting plate 75 into the linear motion of the sliding plate 3, and is an important component connecting the transmission connecting plate 75 and the sliding plate 3. The outside of the second transmission shaft 76 is slidably connected to the top of the transmission connecting plate 75. Inside the end groove, the outer side of the second sliding block 77 is fixedly connected to the outside of the sliding plate 3. The lifting mechanism 4 includes a first sliding block 41, which is used to connect the sliding plate 3 and the cylinder 42, so that the lifting mechanism 4 can move horizontally with the sliding plate 3. The top of the first sliding block 41 is slidably connected to the bottom groove of the sliding plate 3. The bottom of the first sliding block 41 is fixedly connected to the cylinder 42, which is used to drive the connecting block 5 and the fixing mechanism 6 to move up and down, thereby realizing the vertical height adjustment of the transformer. The driving end of the cylinder 42 is fixedly connected to the top of the connecting block 5.
[0037] Working principle: The position of the transformer is detected by a laser rangefinder sensor installed on the outside of the support column 1, thereby controlling the drive end of the second motor 71 to drive the transmission disk 72 to rotate. The transmission shaft 74 fixedly connected to the transmission disk 72 rotates accordingly and slides in the groove inside the transmission connecting plate 75, thereby driving the transmission connecting plate 75 to reciprocate around the fixed shaft 73. The second transmission shaft 76 moves with the swing of the transmission connecting plate 75. The second sliding block 77 drives the sliding plate 3 to slide inside the groove opened inside the horizontal support bar 2, realizing the left and right movement of the sliding plate 3 along the horizontal support bar 2 in the horizontal direction, thereby adjusting the horizontal position of the transformer. At the same time, the first sliding block 41 slides inside the groove at the bottom of the sliding plate 3 and can move synchronously when the horizontal moving mechanism 7 drives the sliding plate 3 to move. The connecting block 5 is moved up and down by the start cylinder 42, thereby realizing the vertical lifting and lowering of the fixing mechanism 6 and the transformer to adapt to different installation height requirements or adjust the horizontality of the transformer for positioning.
[0038] Motor 671 drives pulley 672 to rotate, and pulley 672 drives pulley 674 to rotate via transmission belt 673. Pulley 674 is fixed to one end of threaded rod 62, so that threaded rod 62 rotates inside housing 61. When threaded rod 62 rotates, limit post 63 restricts the rotation of transmission ring 64, so that it can only move along the axial direction of threaded rod 62. As transmission ring 64 moves, fixed brackets 66 can clamp and fix transformer when the distance between fixed brackets 66 is large enough. When it is necessary to release transformer, motor 671 is started in reverse to increase the distance between fixed brackets 66 and release transformer.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
