Description

Technical Field

[0001] The invention relates to the technical field of high-voltage bushing installation, in particular to a device for arranging high-voltage bushings of vehicle-mounted transformers. Background Art

[0002] The high-voltage bushing of the on-board transformer is an insulating device used to lead the high-voltage lead inside the on-board transformer to the outside of the fuel tank. It is mainly composed of a central conductive rod, a porcelain sleeve and some auxiliary insulating components. The central conductive rod is used to transmit high-voltage current, and the porcelain sleeve provides the main insulation protection to prevent current leakage to the surrounding environment.

[0003] However, in the prior art, the vehicle will generate continuous vibration during driving, especially in poor road conditions, such as rugged mountain roads and bumpy roads. The vibration amplitude and frequency of the vehicle will increase significantly. This vibration will be transmitted to the on-board transformer, causing the bolts, nuts and other connectors at the high-voltage bushing connection to be subjected to periodic impact force.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, during the entire connection process, the first rotating sleeve drives the rotating ring to rotate through the fixed ring, gradually applying pressure to the plug-in rod to move it forward, and the sliding block on the top of the plug-in rod slides under the guidance of the inner groove of the top plate, generating friction while compressing the spring inside the groove, thereby enhancing the stability of the overall structure. As the rotating ring continues to rotate, the plug-in rod is smoothly inserted into the plug-in slot of the mounting base, ensuring effective positioning and significantly improving the stability during installation. This connection method not only prevents potential failures caused by looseness, but also ensures that the mounting base is firm and reliable during use. The spring provides buffering during movement, absorbs the impact force generated when the plug-in rod moves, and further enhances durability and reliability.

[0016] 2. In the present invention, when the rotating plate rotates, the arc-shaped hole exerts a force on the positioning rod, causing it to slide on the inner side of the support rod. The stability of the support rod ensures good support for the bottom end of the positioning rod to prevent deviation, thereby gradually approaching the outer surface of the mounting base. Under the coordinated action of the rotating plate and the arc-shaped hole, the three positioning rods move synchronously and gradually gather together to form a clamping state, accurately clamping and positioning the bottom end of the mounting base. This synchronous movement not only improves the positioning accuracy, but also enhances the overall stability of the installation process and effectively prevents loosening. By ensuring the stability of the mounting base during the positioning process, this design significantly improves the reliability of subsequent use. This sophisticated mechanical design, combined with the coordinated action of each component, provides a stable and safe operating basis for the overall system, ensuring high efficiency and safety in practical applications.

[0017] 3. In the present invention, during the installation of the high-voltage bushing body, the mounting base is first inserted into the inner side of the top plate. After ensuring the positioning, the driving motor is started to drive the rotating rod to rotate, exerting a force on the second rotating sleeve, thereby rotating the rotating plate, and the guide block exerts a force on the limit block to push the first rotating sleeve to rotate, thereby realizing the precise positioning of the high-voltage bushing body and the mounting base. During the disassembly stage, the cylinder activates the lifting frame to move up and down, prompting the limit frame and the second rotating sleeve to work together. With the movement of the limit frame, the rotating plate drives the guide block to slide on the inner side of the limit block to ensure its normal lifting and lowering. The rotating plate pushes the mounting base upward to realize quick and convenient separation. This design significantly improves the operating efficiency and the stability of the installation process, effectively avoids the risks caused by looseness or improper operation, ensures the firmness and reliability of the high-voltage bushing body during the installation and disassembly process, and provides a solid guarantee for subsequent use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1 - Figure 6 As shown: the arrangement device of the high-voltage bushing of the vehicle-mounted transformer includes a vehicle-mounted transformer body 1, three high-voltage bushing bodies 2 are arranged on one side of the vehicle-mounted transformer body 1, a locking mechanism 3 is installed at the bottom end of the high-voltage bushing body 2, and a limiting mechanism 4 is installed at the bottom of the locking mechanism 3; The locking mechanism 3 includes a bottom plate 33 and a top plate 31. A mounting hole 37 is provided in the middle of the top plate 31. A support platform 34 is fixedly connected to the center of the top of the bottom plate 33. The top of the support platform 34 is fixedly connected to the bottom of the top plate 31. A slide groove 311 is provided at the bottom of the top plate 31. A sliding block 38 is slidably connected to the inner side of the slide groove 311. A rotating ring 32 is rotatably connected to the outer side of the support platform 34. A plurality of plug-in rods 35 are provided inside the rotating ring 32. The top of the plug-in rod 35 is fixedly connected to the sliding block 38. A spring 36 is provided inside the slide groove 311. One end of the spring 36 abuts against the sliding block 38, and the other end of the spring 36 abuts against the inner wall of the slide groove 311. A groove 321 is provided on the inner wall of the rotating ring 32. One end of the plug-in rod 35 abuts against the groove 321. A mounting base 21 is fixedly connected to the bottom of the high-voltage bushing body 2. A limiting plate 22 is fixedly connected to the outer surface of the middle part of the mounting base 21. A plug-in groove 23 is provided at the bottom end of the mounting base 21. The plug-in groove 23 is plugged with the plug-in rod 35. The bottom of the bottom plate 33 is fixedly connected to the top of the support frame 41, and the mounting hole 37 is plugged with the plug-in groove 23.

[0022] In this embodiment, when the first rotating sleeve 44 drives the rotating ring 32 to rotate through the fixing ring 442, the groove 321 inside the rotating ring 32 gradually applies pressure to the plug rod 35, causing the plug rod 35 to start moving forward. In this process, the sliding block 38 on the top of the plug rod 35 slides along the slide groove 311 inside the top plate 31. This sliding not only generates friction between the sliding block 38 and the slide groove 311, but also forces the spring 36 inside the slide groove 311 to be compressed, thereby enhancing the stability of the overall structure.

[0023] As the rotating ring 32 continues to rotate, the groove 321 will continue to push the plug rod 35 forward, so that one end of the plug rod 35 is firmly inserted into the plug groove 23 on the outer surface of the bottom end of the mounting base 21. This insertion action not only realizes the effective positioning of the mounting base 21, but also significantly improves its stability during the installation process. Through this precise connection method, potential failures caused by looseness can be effectively prevented, ensuring that the mounting base 21 can remain firm and reliable during use.

[0024] In addition, the spring 36 also acts as a buffer during the whole process, and can absorb the impact force generated by the movement of the plug rod 35, further enhancing durability and reliability.

[0025] Embodiment 2: Figure 4 , Figure 7 and Figure 8As shown, the limiting mechanism 4 includes a support frame 41, and a first rotating sleeve 44 is rotatably connected to the top of the support frame 41. A fixing ring 442 is fixedly connected to the top of the inner cavity of the first rotating sleeve 44, and the fixing ring 442 is fixedly connected to the outer surface of the bottom plate 33. A limiting block 441 is fixedly connected to the inner wall of the first rotating sleeve 44, and a guide block 451 is slidably connected to the inner side of the limiting block 441. A rotating plate 45 is arranged on the inner side of the first rotating sleeve 44, and the outer surface of the rotating plate 45 is fixedly connected to the guide block 451, and an arc-shaped hole 48 is opened on the surface of the rotating plate 45. Three support rods 46 are rotatably connected to the top of the support frame 41, and a positioning rod 47 is fixedly connected to the top of one end of the support rod 46. The top of the positioning rod 47 passes through the arc-shaped hole 48, and the positioning rod 47 is slidably connected to the arc-shaped hole 48.

[0026] In this embodiment, when the rotating plate 45 starts to rotate, the arc-shaped hole 48 on its surface will exert a force on the positioning rod 47. This force causes the positioning rod 47 to slide inside the support rod 46. Due to the stability of the support rod 46, the bottom end of the positioning rod 47 can maintain good support, ensuring that it will not deviate during the movement, thereby gradually approaching the outer surface of the bottom end of the mounting base 21.

[0027] Under the coordinated action of the rotating plate 45 and the arc-shaped hole 48, the three positioning rods 47 will move synchronously and gradually gather together. When they gather to a certain position, a clamping state will be formed, effectively clamping and positioning the bottom outer surface of the mounting base 21. This synchronous movement not only improves the positioning accuracy, but also enhances the stability of the entire installation process.

[0028] This design ensures that the mounting base 21 will not become loose during the positioning process, thereby improving its reliability in subsequent use.

[0029] Embodiment 3: According to Figure 7 and Figure 8 As shown, a driving motor 42 is installed at the center of the bottom of the support frame 41, and a rotating rod 421 is fixedly connected to the output end of the driving motor 42. The outer surface of the bottom end of the rotating rod 421 is slidably connected to a limiting frame 422, and a second rotating sleeve 49 is fixedly connected to the top of the limiting frame 422. The top of the second rotating sleeve 49 penetrates the support frame 41, and the top of the support frame 41 is fixedly connected to the bottom of the rotating plate 45. A push plate 431 is inserted on the outside of the limiting frame 422, and a lifting frame 432 is fixedly connected to the top of the pushing plate 431. A cylinder 43 is installed on the inside of the support frame 41, and the top of the cylinder 43 is fixedly connected to the lifting frame 432.

[0030] In this embodiment, when installing the high-voltage bushing body 2, first, the mounting base 21 at the bottom thereof is inserted into the inner side of the top plate 31. During the insertion process, the bottom of the top plate 31 contacts the rotating plate 45. When the positioning is completed, the driving motor 42 starts to operate, driving the rotating rod 421 to rotate. The convex strips on the outer surface of the rotating rod 421 exert a force on the second rotating sleeve 49 to rotate it, thereby driving the rotating plate 45 to rotate accordingly.

[0031] During the rotation of the rotating plate 45, the guide block 451 exerts a force on the limit block 441, pushing the limit block 441 to start rotating the first rotating sleeve 44. Through this series of movements, the high-voltage bushing body 2 and the mounting base 21 can be effectively and accurately positioned.

[0032] During the disassembly and separation stage, the cylinder 43 is activated to drive the lifting frame 432 to move up and down. The movement of the lifting frame 432 will cause the limiting frame 422 to move accordingly, thereby driving the second rotating sleeve 49 to move together. In this process, the structural design of the surface of the rotating rod 421 enables the limiting frame 422 and the second rotating sleeve 49 to work effectively together.

[0033] As the limiting frame 422 moves, the rotating plate 45 will drive the guide block 451 to slide inside the limiting block 441, ensuring the normal lifting and lowering of the rotating plate 45. During the lifting and lowering process, the rotating plate 45 pushes the mounting base 21 upward, thereby achieving convenient and rapid separation. This design not only improves the efficiency of the operation, but also ensures the stability of the high-voltage bushing body 2 during the installation and removal process, avoiding potential risks caused by looseness or improper operation.

[0034] The use method and working principle of the device: When installing the high-voltage bushing body 2, first insert the mounting base 21 at the bottom into the inner side of the top plate 31. During the insertion process, the bottom of the top plate 31 contacts the rotating plate 45. When the positioning is completed, the driving motor 42 starts to operate, driving the rotating rod 421 to rotate. The convex strips on the outer surface of the rotating rod 421 will exert a force on the second rotating sleeve 49 to rotate it, thereby driving the rotating plate 45 to rotate accordingly.

[0035] During the rotation of the rotating plate 45, the guide block 451 exerts a force on the limit block 441, pushing the limit block 441 to start rotating the first rotating sleeve 44. Through this series of movements, the high-voltage bushing body 2 and the mounting base 21 can be effectively and accurately positioned.

[0036] When the rotating plate 45 starts to rotate, the arc-shaped hole 48 on its surface will exert a force on the positioning rod 47. This force causes the positioning rod 47 to slide inside the support rod 46. Due to the stability of the support rod 46, the bottom end of the positioning rod 47 can maintain good support, ensuring that it will not deviate during the movement, thereby gradually approaching the outer surface of the bottom end of the mounting base 21.

[0037] Under the coordinated action of the rotating plate 45 and the arc-shaped hole 48, the three positioning rods 47 will move synchronously and gradually gather together. When they gather to a certain position, a clamping state will be formed, effectively clamping and positioning the bottom outer surface of the mounting base 21. This synchronous movement not only improves the positioning accuracy, but also enhances the stability of the entire installation process.

[0038] This design ensures that the mounting base 21 will not loosen during the positioning process, thereby improving its reliability in subsequent use. In addition, the flexibility of the positioning rod 47 is combined with the stability of the support rod 46.

[0039] When the first rotating sleeve 44 drives the rotating ring 32 to rotate through the fixing ring 442, the groove 321 inside the rotating ring 32 gradually applies pressure to the plug rod 35, causing the plug rod 35 to start moving forward. In this process, the sliding block 38 on the top of the plug rod 35 slides along the slide groove 311 inside the top plate 31. This sliding not only generates friction between the sliding block 38 and the slide groove 311, but also forces the spring 36 inside the slide groove 311 to be compressed, thereby enhancing the stability of the overall structure.

[0040] As the rotating ring 32 continues to rotate, the groove 321 will continue to push the plug rod 35 forward, so that one end of the plug rod 35 is firmly inserted into the plug groove 23 on the outer surface of the bottom end of the mounting base 21. This insertion action not only realizes the effective positioning of the mounting base 21, but also significantly improves its stability during the installation process. Through this precise connection method, potential failures caused by looseness can be effectively prevented, ensuring that the mounting base 21 can remain firm and reliable during use.

[0041] In addition, the spring 36 also acts as a buffer during the whole process, and can absorb the impact force generated by the movement of the plug rod 35, further enhancing durability and reliability.

[0042] During the disassembly and separation stage, the cylinder 43 is activated to drive the lifting frame 432 to move up and down. The movement of the lifting frame 432 will cause the limiting frame 422 to move accordingly, thereby driving the second rotating sleeve 49 to move together. In this process, the structural design of the surface of the rotating rod 421 enables the limiting frame 422 and the second rotating sleeve 49 to work effectively together.

[0043] As the limiting frame 422 moves, the rotating plate 45 will drive the guide block 451 to slide inside the limiting block 441, ensuring the normal lifting and lowering of the rotating plate 45. During the lifting and lowering process, the rotating plate 45 pushes the mounting base 21 upward, thereby achieving convenient and rapid separation. This design not only improves the efficiency of the operation, but also ensures the stability of the high-voltage bushing body 2 during the installation and removal process, avoiding potential risks caused by looseness or improper operation.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
