Technical Field

[0001] This utility model relates to the field of column-type pressure regulator transmission equipment, and in particular to a device for a servo motor on a column-type pressure regulator to be mounted on a drive shaft for transmission. Background Technology

[0002] Column-type voltage regulators are widely used in power systems and voltage stabilizers to regulate voltage to meet the needs of different equipment.

[0003] Traditional column-type voltage regulators mostly use manual adjustment or simple mechanical transmission methods, which have problems such as low adjustment accuracy, slow response speed, and inconvenient operation. With the development of automation technology, servo motors, due to their advantages such as high precision and fast response, are gradually being used in the transmission systems of voltage regulators.

[0004] However, the existing integration method of servo motor and column voltage regulator has problems such as complicated installation, low transmission efficiency and poor reliability, which limits its application in column voltage regulator. To solve the above problems, a device is proposed in which the servo motor on the column voltage regulator is mounted on the drive shaft for transmission. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device in which a servo motor on a column-type voltage regulator is mounted on the drive shaft for transmission, aiming to improve the problems of cumbersome installation, high cost, low transmission efficiency, and poor reliability in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for a servo motor mounted on a drive shaft of a column-type voltage regulator, comprising a support frame, a transmission assembly at the top of the support frame, a slider connected to the transmission assembly via a chain drive, a detection plate fixedly connected between two sets of sliders, a column-shaped voltage regulator at the center of the support frame, the transmission assembly comprising a servo motor, a servo motor mounting bracket, a drive shaft one, and a drive shaft two, the servo motor being directly coaxially connected to drive shaft one and drive shaft two via a double-headed output shaft, a gear one fixedly connected to the outer wall of drive shaft one, a gear two fixedly connected to the outer wall of drive shaft two, and a mounting bracket fixedly installed at the top of the support frame.

[0012] As a further description of the above technical solution: an absolute encoder is installed at one end of the drive shaft.

[0013] As a further description of the above technical solution: the teeth of gear one and gear two respectively mesh with each other in the tooth groove of the chain.

[0021] 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.

[0022] Reference Figures 1-2 This utility model provides an embodiment of a device for a servo motor mounted on a drive shaft of a column-type voltage regulator. The device includes a support frame 1, which serves as the basic load-bearing structure and provides an installation reference for components such as the transmission assembly 6, slider 3, and detection plate 4. The slider 3 is slidably connected in a groove on the inner wall of the support frame 1, which provides a sliding track for the slider 3, ensuring the straightness and stability of its movement during transmission. The overall frame structure ensures the installation and positioning of the column-type voltage regulator 5 and isolates external environmental interference from the internal transmission mechanism. The transmission assembly 6 is located at the top of the support frame 1. The moving component 6 is connected to the slider 3 via the chain 2. The chain 2 serves as the transmission medium, connecting the gear 65 and gear 66 of the transmission component 6 to the slider 3. The driving force of the servo motor 61 is transmitted through the meshing of the gears. The chain 2 can achieve power transmission over a long distance. The tension of the chain 2 can be optimized by adjusting the distance between the drive shafts to ensure smooth transmission. A detection plate 4 is fixedly connected between the two sets of sliders 3. The design of the slider 3 converts the transmission power of the chain 2 into linear motion. The two sets of sliders 3 are rigidly connected to drive the detection plate 4 to move synchronously, ensuring the consistency and reliability of the movement of the detection plate 4.

[0023] Reference Figures 1-2 A cylindrical voltage regulator 5 is installed at the center of the support frame 1. The detection sensor in the detection plate 4 is in contact with the outer wall of the cylindrical voltage regulator 5. The detection plate 4 serves as the mounting carrier for the detection sensor. It is driven by the slider 3 to move along the outer wall of the cylindrical voltage regulator 5 to realize real-time detection of the surface parameters of the voltage regulator. The detection sensor is in contact with the outer wall of the voltage regulator, converting the physical signal into an electrical signal and feeding it back to the servo motor 61 control system to form a closed-loop regulation and ensure the voltage regulation accuracy. The rigid structure of the detection plate 4 can avoid measurement errors caused by deformation during the detection process. The cylindrical voltage regulator 5 is the core voltage regulation component. It realizes voltage regulation by changing the number of turns of the internal winding. The outer wall is in contact with the sensor of the detection plate 4 to provide a detection reference surface. Under the drive of the transmission component 6, its external voltage regulation component realizes axial movement through the transmission of gear 1 65, gear 2 66 and chain 2, thereby changing the output voltage. It works in conjunction with the support frame 1, mounting bracket 62 and other components to form a stable voltage regulation working environment.

[0024] Reference Figures 1-2The transmission assembly 6 includes a servo motor 61, a mounting bracket 62, a first drive shaft 63, and a second drive shaft 64. The servo motor 61 is detachably connected inside the mounting bracket 62. The servo motor 61 is the power source of the equipment and directly drives the first drive shaft 63 and the second drive shaft 64 to rotate coaxially through the dual-head output shaft, achieving high-precision power output. The motor controller dynamically adjusts the speed and direction of rotation based on the position signal fed back by the detection board 4 to ensure the response speed and adjustment accuracy of the pressure regulation process. The mounting bracket 62 is fixedly installed on the top of the support frame 1. A rubber shock-absorbing pad is provided between the mounting bracket 62 and the cylindrical pressure regulator 5. The mounting bracket 62 is used to fix the servo motor 61. Its internal double-shaft hole structure ensures that the motor output shaft is aligned with the first drive shaft 63 and the second drive shaft 64. The coaxiality of the mounting bracket 62 is provided by bolts to the top of the support frame 1, which provides a rigid mounting reference. The rubber shock-absorbing pad between the mounting bracket 62 and the cylindrical voltage regulator 5 can attenuate the vibration of the motor operation and prevent the vibration from being transmitted to the voltage regulator and affecting the voltage regulation stability. The servo motor 61 is directly coaxially connected to the first drive shaft 63 and the second drive shaft 64 through the double-headed output shaft. The first drive shaft 63 and the second drive shaft 64 are used to transmit the output power of the left side of the servo motor 61 to ensure reliable torque transmission. The first gear 65 and the second gear 66 fixed on the outer wall cooperate with the chain 2 to drive the left slider 3. An absolute encoder is installed at the end to monitor the shaft rotation angle in real time and provide accurate position feedback for the control system. The bearing support 67 is pre-tightened to improve the rigidity and rotation accuracy of the shaft system.

[0025] Reference Figures 1-2 A gear 65 is fixedly connected to the outer wall of the drive shaft 63, and an absolute encoder is installed at the end of the drive shaft 63. A gear 66 is fixedly connected to the outer wall of the drive shaft 64. The teeth of gear 65 and gear 66 mesh with each other in the tooth grooves of the chain 2. The function of gears 65 and 66 is to convert the rotational motion of the drive shaft 63 and drive shaft 64 into the linear motion of the chain 2. The gear module and number of teeth are designed according to the pressure adjustment speed requirements, which can realize torque amplification or reduction to meet different pressure adjustment needs. For load requirements, the end of drive shaft 63 and bearing support 67 are pre-tightened, and the end of drive shaft 64 and bearing support 68 are pre-tightened. High-precision deep groove ball bearings are used to support the ends of drive shaft 63 and drive shaft 64, bearing radial loads and limiting axial displacement of the shafts. The pre-tightening assembly process eliminates bearing clearance, reduces rotational friction, and improves shaft rigidity and transmission smoothness. The bearing housing is fixedly connected to the support frame 1 to ensure shaft positioning accuracy.

[0026] Working principle: The servo motor 61 serves as the core power source. It is directly connected to the active shaft 63 and the active shaft 64 through the dual-head output shaft to achieve high-precision torque output. After receiving the position signal fed back by the detection board 4, the motor controller dynamically adjusts the motor speed and direction to ensure the voltage regulation response speed and control accuracy. The rubber shock-absorbing pad attenuates the vibration of the motor operation and avoids the vibration from being transmitted to the cylindrical voltage regulator 5, which affects the voltage regulation stability.

[0027] The first drive shaft 63 and the second drive shaft 64 rotate synchronously with the servo motor 61. The gears 65 and 66 on their outer walls mesh with the chain 2 through tooth grooves, converting the rotational motion into the linear motion of the chain 2. The gear module and number of teeth are designed according to the voltage regulation load requirements. The tension of the chain 2 is optimized by adjusting the distance between the drive shafts to ensure smooth transmission. The chain 2 drives the slider 3 to slide linearly along the groove on the inner wall of the support frame 1. The two sets of sliders 3 are rigidly connected to drive the detection plate 4 to move synchronously. As the slider 3 moves, the detection sensor mounted on the detection plate 4 contacts the outer wall of the cylindrical voltage regulator 5, and collects physical signals such as the position and contact resistance of the voltage regulation component in real time. These signals are converted into electrical signals and fed back to the control system of the servo motor 61. The control system calculates the deviation between the actual voltage regulation position and the target value based on the feedback signal, and drives the servo motor 61 to fine-tune the speed or direction, forming a "detection-calculation-drive-adjustment" closed loop to ensure voltage regulation accuracy. The rigid structure of the detection plate 4 avoids measurement errors caused by deformation. Its movement path is parallel to the outer wall of the voltage regulator to ensure the consistency of the detection reference plane.

[0028] The ends of drive shaft 1 (63) and drive shaft 2 (64) are fixed by bearing support 1 (67) and bearing support 2 (68), respectively. High-precision deep groove ball bearings and pre-tightening assembly process are used to eliminate shaft clearance and improve rotational rigidity. An absolute encoder is installed at the ends of drive shaft 1 (63) and drive shaft 2 (64) to monitor the shaft rotation angle in real time and provide a precise position reference for closed-loop control. The cylindrical voltage regulator 5 achieves voltage regulation by adjusting the internal winding turns ratio. Its external voltage regulating component is linked with the transmission component 6 of chain 2. Driven by gear 1 (65), gear 2 (66), and chain 2, it moves axially to change the winding contact position, thereby outputting the target voltage. The support frame 1 provides a rigid reference for the overall structure, isolates external interference, and ensures that the voltage regulator works in a stable environment.
