Description

Technical Field

[0001] This utility model relates to the technical field of test power supply control devices, specifically a test power supply control device that is easy to transfer. Background Technology

[0002] Test power supply control devices are specifically designed for controlling and monitoring test power supplies, playing a vital role in power maintenance, electrical equipment testing, and other fields. These devices are used to control the normal operation, synchronous work, fault isolation, and status indication of test equipment and measurement systems. They are widely used in power supply companies, large factories, metallurgical plants, power plants, railways, and other locations requiring power maintenance and testing. However, existing test power supply control devices are inconvenient to relocate, typically requiring manual handling or external transport equipment, impacting their effectiveness and convenience.

[0003] According to the patent application published on the Internet, a test power control device that is easy to transfer (authorization announcement number: CN220687917U) is described as including "chassis, base, shock absorption box" etc., to realize the transfer work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This easily portable test power control device utilizes a chassis, base, and shock-absorbing box for relocation. During use, the device is moved using casters. After relocation, operators must rotate a turntable to bring the screw-driven support block into contact with the ground, requiring this process to be repeated one by one, which is inefficient. Furthermore, the casters cannot be lifted, making them susceptible to movement due to vibration or external impacts during use, affecting the stability of the test power control device. Therefore, improvements to this device are necessary. Utility Model Content

[0006] The purpose of this invention is to provide a test power supply control device that is easy to transfer, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a test power supply control device that is easy to transfer, including a support frame, a transfer mechanism at the bottom of the support frame, and a fixing mechanism at the top of the support frame;

[0008] The transfer mechanism includes a support platform, which is fixedly connected to the bottom of a support frame. A base is fixedly connected to the bottom of the support platform. A first servo motor is fixedly connected to the bottom of the support platform. A one-way threaded rod is fixedly connected to the top of the first servo motor. The top of the one-way threaded rod is located at the bottom of the fixed mechanism. A movable frame is threadedly connected to the periphery of the one-way threaded rod. A limit frame is slidably connected to the periphery of the movable frame. A mounting plate is fixedly connected to the bottom of the movable frame. A fixing sleeve is fixedly connected to the bottom of the mounting plate. A universal wheel is inserted into the fixing sleeve. A fixing pin is threadedly connected to the inside of the universal wheel.

[0009] Preferably, the limiting frame is fixedly connected to the top of the support platform, and the one-way threaded rod is rotatably connected to the inside of the support platform, so that the moving frame can move more stably under the action of the limiting frame.

[0010] Preferably, the fixing pin passes through the inside of the fixing sleeve, and the fixing sleeve and the universal wheel are respectively provided with fixing grooves, and the two fixing grooves correspond to each other. The fixing pin is threaded into the fixing groove, which facilitates the fixing of the universal wheel under the action of the fixing pin, and also facilitates installation and disassembly.

[0011] Preferably, the fixing sleeve has an installation groove inside, and the universal wheel is inserted into the installation groove, which facilitates the installation of the universal wheel under the action of the installation groove.

[0012] Preferably, the fixing mechanism includes a fixed platform, which is fixedly connected to the top of the load-bearing frame. A vibration damping seat is fixedly connected to the bottom of the fixed platform. The test power control device body is slidably connected to the inner side of the vibration damping seat. A second servo motor is fixedly connected to the left side of the fixed platform. A bidirectional threaded rod is fixedly connected to the right side of the second servo motor. A movable seat is threadedly connected to the outer side of the bidirectional threaded rod. The movable seat is slidably connected to the inside of the fixed platform. A sliding rod is slidably connected inside the movable seat. A limit sleeve is fixedly connected inside the limit sleeve. A telescopic rod is fixedly connected inside the limit sleeve. A connecting shaft is fixedly connected to the right side of the telescopic rod. The connecting shaft is slidably connected inside the limit sleeve. A spring is sleeved around the telescopic rod. A clamping plate is fixedly connected to the right side of the connecting shaft. The clamping plate is slidably connected to the outer side of the test power control device body.

[0013] Preferably, the right side of the bidirectional threaded rod is rotatably connected to the fixed platform, the slide rod is fixedly connected to the fixed platform, and the bottom of the fixed platform is rotatably connected to the top of the unidirectional threaded rod, so as to facilitate the movement of the movable seat under the action of the bidirectional threaded rod and the slide rod.

[0014] Preferably, the left side of the spring is fixedly connected to the limiting sleeve, the right side of the spring is fixedly connected to the left side of the connecting shaft, and a rubber pad is provided on the inner side of the clamping plate to facilitate buffering of the clamping plate under the action of the spring. When the device is subjected to vibration or external impact, the spring can absorb some of the energy.

[0015] Compared with the prior art, this utility model provides a test power supply control device that is easy to transfer, and has the following beneficial effects:

[0016] 1. This easily transferable test power control device, through its transfer mechanism, allows for stable up-and-down movement of the mobile frame under the support platform when the device needs to be moved. The first servo motor drives the one-way threaded rod to rotate. Since the mobile frame is threadedly connected to the one-way threaded rod and its periphery is slidably connected to the limiting frame, the mobile frame can move stably up and down under the drive of the one-way threaded rod. When the device needs to be moved, the first servo motor is activated, causing the mobile frame to descend and the casters at the bottom of the mounting plate to contact the ground, thus supporting the device and facilitating movement via the casters. Compared to traditional handling methods, this significantly saves manpower and time costs and improves transfer efficiency. Furthermore, the caster design greatly enhances the ease of moving the test power control device during transport. Once the transfer is complete, the base can simply contact the ground, ensuring the stability of the test power control device. The casters are fixed in the mounting sleeve by fixing pins, facilitating replacement, installation, and disassembly.

[0017] 2. This easily transferable test power control device, through its fixed mechanism, allows for easy relocation. When the device needs to be moved, the main body is slidably connected to the inner side of the vibration damping seat, stabilizing the device. The second servo motor inside the fixed platform drives the bidirectional threaded rod to rotate, which in turn moves the movable seat connected to the outer thread of the rod. The sliding connection between the movable seat and the sliding rod ensures smooth movement. The movable seat is connected to the clamping plate via a telescopic rod and a connecting shaft. When the movable seat moves, the clamping plate tightly grips the main body of the test power control device. Rubber pads on the inner side of the clamping plate increase friction, preventing shaking or displacement during relocation and further improving the reliability of the fixation. The limit sleeve and spring design provide buffering and fine-tuning. When the device is subjected to vibration or external impact, the spring absorbs some energy. Through the extension and retraction of the telescopic rod and the sliding of the connecting shaft within the limit sleeve, the clamping plate adaptively adjusts the clamping force on the device, ensuring the device remains in a stable fixed state.

[0030] Example 1

[0031] Please see Figure 1-7 This utility model provides a technical solution: a test power control device that is easy to transfer, including a support frame 1, a transfer mechanism 2 at the bottom of the support frame 1, and a fixing mechanism 3 at the top of the support frame 1;

[0032] The transfer mechanism 2 includes a support platform 21, which is fixedly connected to the bottom of the support frame 1.

A movable frame 26 is threadedly connected to the periphery of the one-way threaded rod 24. A limit frame 25 is slidably connected to the periphery of the movable frame 26. A mounting plate 27 is fixedly connected to the bottom of the movable frame 26. A fixing sleeve 28 is fixedly connected to the bottom of the mounting plate 27. A universal wheel 291 is inserted into the fixing sleeve 28. A fixing pin 29 is threadedly connected inside the universal wheel 291.

[0033] The limiting frame 25 is fixedly connected to the top of the support platform 21, and the one-way threaded rod 24 is rotatably connected to the inside of the support platform 21, so that the moving frame 26 can move more stably under the action of the limiting frame 25.

[0034] Example 2

[0035] Please see Figure 1-7Furthermore, based on Embodiment 1, the fixing mechanism 3 further includes a fixing platform 31, which is fixedly connected to the top of the load-bearing frame 1. A vibration damping seat 32 is fixedly connected to the bottom of the fixing platform 31. The test power control device body 33 is slidably connected to the inner side of the vibration damping seat 32. A second servo motor 34 is fixedly connected to the left side of the fixing platform 31. A bidirectional threaded rod 35 is fixedly connected to the right side of the second servo motor 34. A movable seat 36 is threadedly connected to the outer periphery of the bidirectional threaded rod 35. The movable seat 36 is slidably connected to the inside of the fixing platform 31. A sliding rod 38 is slidably connected inside the movable seat 36. A limiting sleeve 37 is fixedly connected inside the movable seat 36. A telescopic rod 391 is fixedly connected inside the limiting sleeve 37. A connecting shaft 393 is fixedly connected to the right side of the telescopic rod 391. The connecting shaft 393 is slidably connected inside the limiting sleeve 37. A spring 392 is sleeved around the telescopic rod 391. A clamping plate 39 is fixedly connected to the right side of the connecting shaft 393. The clamping plate 39 is slidably connected to the outer periphery of the test power control device body 33.

[0036] The right side of the bidirectional threaded rod 35 is rotatably connected to the fixed platform 31, and the slide rod 38 is fixedly connected to the fixed platform 31. The bottom of the fixed platform 31 is rotatably connected to the top of the unidirectional threaded rod 24, so that the moving seat 36 can be moved under the action of the bidirectional threaded rod 35 and the slide rod 38. The left side of the spring 392 is fixedly connected to the limiting sleeve 37, and the right side of the spring 392 is fixedly connected to the left side of the connecting shaft 393. A rubber pad is provided on the inner side of the clamping plate 39, so that the clamping plate 39 can be buffered under the action of the spring 392. When the device is subjected to vibration or external impact, the spring 392 can absorb some energy.

[0037] In actual operation, when this device is in use, and when the test power control device needs to be moved, the test power control device body 33 is slidably connected to the inner side of the vibration damping seat 32, so that the test power control device body 33 is in a preliminary stable state. At the same time, the second servo motor 34 drives the movable seat 36, which is threadedly connected to the outer side of the bidirectional threaded rod 35, to move. The movable seat 36 slides around the slide rod 38, and under the action of the movable seat 36, the limiting sleeve 37, the telescopic rod 391, the connecting shaft 393, and the clamping plate 39 move, and the clamping plate 39 is slidably connected to the test power control device. The test power control device body 33 can be fixed around the device body 33. The inner side of the clamping plate 39 is provided with a rubber pad to increase the friction and prevent the device from shaking or shifting during the transfer process, which further improves the reliability of the fixation. The design of the limiting sleeve 37 and the spring 392 plays the role of buffering and fine adjustment. When the device is subjected to vibration or external impact, the spring 392 can absorb some energy. Through the extension and retraction of the telescopic rod 391 and the sliding of the connecting shaft 393 in the limiting sleeve 37, the clamping plate 39 can adaptively adjust the clamping force on the device body to ensure that the device is always in a stable fixed state.

[0038] Once the fixing is complete, the first servo motor 23 can drive the movable frame 26, which is connected to the outer thread of the one-way threaded rod 24, to move. The movable frame 26 moves within the limit frame 25, which in turn drives the mounting plate 27, the fixing sleeve 28, and the casters 291 to move. The casters 291 then contact the ground, lifting the base 22. The casters 291 greatly improve the ease of moving the test power control device body 33 during the movement, allowing the test power control device body 33 to be moved. When the transfer is complete, the casters 291 can be moved upward away from the ground again by the first servo motor 23 and the one-way threaded rod 24, and the base 22 can then contact the ground. This will restore the base 22, the load-bearing frame 1, the fixing platform 31, and the test power control device body 33 to a stable state, ensuring the stability of the test power control device body 33.

[0039] When the caster wheel 291 wears out after prolonged use, the fixing pin 29 can be removed to release the limit on the caster wheel 291, and the worn caster wheel 291 can be replaced to ensure stability during the transfer process. The model of the test power control device 33 used in this case is MY1007.
