Description

Technical Field

[0001] This utility model belongs to the field of industrial frequency converter technology, and in particular relates to a vibration-resistant industrial frequency converter. Background Technology

[0002] Industrial frequency converters, as key power devices that use frequency conversion technology and microelectronics to control AC motors by changing the frequency of the motor's operating power supply, play an important role in the process of industrial automation. They are widely used in various industrial scenarios, covering fields such as machinery manufacturing, chemical production, and metallurgical processing, and greatly improve the energy-saving effect and speed regulation accuracy of motor operation. In actual industrial environments, the motors driven by industrial frequency converters generate vibrations during operation due to their own mechanical structure characteristics and unbalanced loads, which are then transmitted to the frequency converters. In addition, the complex and diverse industrial sites, the operation of large mechanical equipment, and the vibration of workshop floors, among other external factors, can also easily cause the frequency converters to be subjected to vibration and shock. However, existing industrial frequency converters generally lack effective anti-vibration structures, which leads to the loosening and detachment of electronic components and circuit board solder joints inside the frequency converter under long-term vibration, resulting in poor electrical connections and causing malfunctions. Utility Model Content

[0003] The purpose of this invention is to provide a vibration-resistant industrial frequency converter. By incorporating a buffer mechanism, specifically, when the industrial frequency converter body is subjected to vibration, the vibration is transmitted to the mounting base, causing the transmission rod to shift, which in turn moves the transmission plate. At this time, the damper utilizes its own damping characteristics to create resistance to the movement of the transmission plate, and the spring generates a reverse elastic force due to compression or tension. Together, these two mechanisms buffer and disperse the vibration energy for the first time. Simultaneously, the movement of the transmission plate drives the connecting plate to move, pushing the slider to slide on the fixed rod and compress the disc spring. The disc spring, with its own structure and elasticity, further absorbs and disperses the remaining vibration energy, thereby effectively weakening the adverse effects of vibration on the industrial frequency converter body, ensuring its stable operation, extending its service life, reducing the number of maintenance failures caused by vibration, improving the stability and reliability of industrial production, and solving the problem that existing industrial frequency converters generally lack effective vibration-resistant structures.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a vibration-resistant industrial frequency converter, comprising an industrial frequency converter body and further comprising: a buffer mechanism disposed on the rear side of the industrial frequency converter body, the buffer mechanism being used to buffer and disperse vibrations received by the industrial frequency converter body, the buffer mechanism comprising a buffer seat and a mounting seat; and a mounting mechanism disposed on the mounting seat, the mounting mechanism being used for quick installation and disassembly of the industrial frequency converter body, the mounting mechanism comprising two connecting slots formed on the front side of the mounting seat, and two connecting blocks fixedly connected to the rear side of the industrial frequency converter body, the rear sides of the two connecting blocks extending into the corresponding connecting slots and slidingly connected to the corresponding connecting slots. Since the tops of the two connecting slots extend to the top of the mounting seat, when installing the industrial frequency converter body, the two connecting blocks on the rear side of the industrial frequency converter body are first slid into the two connecting slots through the top of the mounting seat and slid downwards, so that the bottoms of the two connecting blocks contact the bottom walls of the corresponding connecting slots respectively.

[0005] Furthermore, the buffer mechanism also includes a first buffer component, which is disposed inside the buffer seat and is used to buffer and disperse the vibration received by the industrial frequency converter body for the first time; and a second buffer component, which is disposed inside the buffer seat and is used to cooperate with the first buffer component to further buffer and disperse the vibration received by the buffer seat; both the first buffer component and the second buffer component are provided in two sets, and the two sets of the first buffer component and the second buffer component are symmetrically arranged on the buffer seat.

[0006] Furthermore, the first buffer assembly includes two support blocks fixedly connected to the inner wall of the rear side of the buffer seat. A damper is fixedly connected to the front side of each of the two support blocks. A spring is sleeved on the outer wall of each of the two dampers. The two support blocks are symmetrically arranged inside the buffer seat, and the dampers are connected to the corresponding support blocks by bolts.

[0007] Furthermore, a transmission plate is fixedly connected to the movable ends of the two dampers. Two transmission rods are fixedly connected to the side of the transmission plate away from the dampers. The ends of the two transmission rods away from the transmission plate extend to the outside of the buffer seat and are slidably connected to the buffer seat. The ends of the two transmission rods away from the transmission plate are fixedly connected to the mounting base. One end of each of the two springs is fixedly connected to the corresponding support block, and the other end is fixedly connected to the transmission plate.

[0008] Furthermore, the second buffer assembly includes a fixed rod fixedly connected between two support blocks. Two sliders are slidably connected to the outer wall of the fixed rod. A disc spring is sleeved on the outer wall of the fixed rod. Connecting plates are respectively hinged between the two sliders and the transmission plate. The two ends of the disc spring abut against the two sliders respectively, and the two connecting plates are symmetrically hinged to the transmission plate on the side away from the corresponding slider.

[0009] Furthermore, the installation mechanism also includes an installation groove inside the mounting base, a movable block slidably connected to the inner wall of the installation groove, a locking groove on the industrial frequency converter body, a locking block fixedly connected to the side of the movable block near the industrial frequency converter body, the locking block extending into the locking groove and slidably connected to the locking groove on the side of the locking block near the industrial frequency converter body, the locking block being fixedly connected to the movable block by welding, and both the locking block and the locking groove being designed to be conical, with the locking block and the locking groove being compatible.

The push block is configured as an isosceles trapezoid, and the inclined side near the moving block is slidably connected to the inclined side of the moving block.

[0011] Furthermore, a limiting groove is formed on the side of the moving block near the push block, and a limiting block is fixedly connected to the side of the push block near the moving block.

The sliding cooperation between the limiting groove and the limiting block limits the push block and the moving block, and also makes the push block and the moving block slide relative to each other.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a buffer mechanism. Specifically, when the industrial frequency converter is subjected to vibration, the vibration is transmitted to the mounting base, causing the transmission rod to shift and thus pushing the transmission plate to move. At this time, the damper uses its own damping characteristics to create resistance to the movement of the transmission plate, and the spring generates a reverse elastic force due to compression or tension. The two work together to buffer and disperse the vibration energy for the first time. Simultaneously, the movement of the transmission plate drives the connecting plate to move, pushing the slider to slide on the fixed rod and compress the disc spring. The disc spring, with its own structure and elasticity, further absorbs and disperses the remaining vibration energy, thereby effectively weakening the adverse effects of vibration on the industrial frequency converter, ensuring its stable operation, extending its service life, reducing the number of maintenance failures caused by vibration, and improving the stability and reliability of industrial production.

[0013] 2. This utility model, through the setting of an installation mechanism, specifically, when installing the industrial frequency converter, first slides the two connecting blocks on the rear side of the industrial frequency converter body from the top of the mounting base into the two connecting slots and slides them downwards to the bottom. Then, rotate the bolt to drive the push block to move down.

When disassembling, rotate the bolt in the opposite direction to make the locking block exit the locking slot, and the industrial frequency converter body can be quickly removed. This realizes the rapid installation and disassembly of the industrial frequency converter body without the need for complicated tools, greatly shortens the installation and maintenance time, improves the convenience of operation, facilitates efficient operation during equipment maintenance or replacement, and ensures the continuity of industrial production.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 As shown, this utility model is a vibration-resistant industrial frequency converter, including an industrial frequency converter body 1, and further including: a buffer mechanism 2, which is disposed on the rear side of the industrial frequency converter body 1, and is used to buffer and disperse the vibration received by the industrial frequency converter body 1. The buffer mechanism 2 includes a buffer seat 21 and a mounting seat 211; and a mounting mechanism 3, which is disposed on the mounting seat 211, and is used for quick installation and disassembly of the industrial frequency converter body 1. The mounting mechanism 3 includes two connecting slots 31 opened on the front side of the mounting seat 211, and two connecting blocks 311 are fixedly connected to the rear side of the industrial frequency converter body 1. The rear sides of the two connecting blocks 311 are both extended... The buffer mechanism 2 also includes a first buffer component 22, which is disposed inside the buffer seat 21 and is used to buffer and disperse the vibration received by the industrial frequency converter body 1 for the first time; a second buffer component 23, which is disposed inside the buffer seat 21 and is used to cooperate with the first buffer component 22 to further buffer and disperse the vibration received by the buffer seat 21; two sets of the first buffer component 22 and the second buffer component 23 are provided, and the two sets of the first buffer component 22 and the second buffer component 23 are symmetrically arranged on the buffer seat 21.

[0020] The first buffer assembly 22 includes two support blocks 221 fixedly connected to the inner rear wall of the buffer seat 21. A damper 222 is fixedly connected to the front side of each support block 221, and a spring 223 is fitted onto the outer wall of each damper 222. A transmission plate 224 is fixedly connected to the movable end of each damper 222. Two transmission rods 225 are fixedly connected to the side of the transmission plate 224 away from the dampers 222. The ends of the two transmission rods 225 away from the transmission plate 224 extend to the outside of the buffer seat 21 and are slidably connected to it. The ends of the two transmission rods 225 away from the transmission plate 224 are fixedly connected to a mounting base 211, and the ends of the two transmission rods 225 away from the transmission plate 224 are fixedly connected to the mounting base 211 by welding. The second buffer assembly 23 includes a fixed rod 231 fixedly connected between the two support blocks 221. Two sliders 232 are slidably connected to the outer wall of the fixed rod 231, and a disc is fitted onto the outer wall of the fixed rod 231. Spring 233, two sliders 232, and transmission plate 224 are respectively hinged to connecting plates 234; by setting buffer mechanism 2, specifically when the industrial frequency converter body 1 is vibrated, the vibration is transmitted to the mounting base 211, which drives the transmission rod 225 to move, and then pushes the transmission plate 224 to move. At this time, the damper 222 uses its own damping characteristics to form resistance to the movement of the transmission plate 224, and the spring 223 generates a reverse elastic force due to compression or tension. The two work together to buffer and disperse the vibration energy for the first time; at the same time, the movement of the transmission plate 224 drives the connecting plate 234 to move, pushing the slider 232 to slide on the fixed rod 231 and squeeze the disc spring 233. The disc spring 233 absorbs and disperses the remaining vibration energy with its own structure and elasticity, thereby effectively weakening the adverse effects of vibration on the industrial frequency converter body 1, ensuring its stable operation, extending its service life, reducing the number of maintenance failures caused by vibration, and improving the stability and reliability of industrial production.

[0021] The mounting mechanism 3 also includes a mounting groove 32 formed inside the mounting base 211. A movable block 321 is slidably connected to the inner wall of the mounting groove 32. A locking groove 322 is formed on the industrial frequency converter body 1. A locking block 323 is fixedly connected to the side of the movable block 321 near the industrial frequency converter body 1. The side of the locking block 323 near the industrial frequency converter body 1 extends into the locking groove 322 and is slidably connected to the locking groove 322. A bolt 324 is threadedly connected to the top of the mounting base 211. The bottom end of the bolt 324 extends into the mounting groove 32. A push block 325 is rotatably connected to the bottom end of the bolt 324. A limit groove 326 is formed on the side of the movable block 321 near the push block 325. A limit block 327 is fixedly connected to the side of the push block 325 near the movable block 321. The side of the limit block 327 away from the push block 325 extends into the limit groove 326 and is slidably connected to the limit groove 326. 7. The inverter body is fixedly connected to the push block 325 by welding. Specifically, when installing the industrial inverter, the two connecting blocks 311 on the rear side of the inverter body 1 are slid from the top of the mounting base 211 into the two connecting slots 31 and then slid downwards to the bottom. Then, the bolt 324 is rotated to move the push block 325 downwards. The push block 325, with the sliding cooperation of the limiting slot 326 and the limiting block 327, pushes the moving block 321 closer to the industrial inverter body 1, allowing the locking block 323 to insert into the locking slot 322 to complete the installation. During disassembly, the bolt 324 is rotated in the opposite direction to disengage the locking block 323 from the locking slot 322, allowing the industrial inverter body 1 to be quickly removed. This achieves rapid installation and disassembly of the industrial inverter body 1 without the need for complex tools, significantly shortening installation and maintenance time, improving operational convenience, facilitating efficient operation during equipment maintenance or replacement, and ensuring the continuity of industrial production.

[0022] A specific application of this embodiment is as follows: When installing an industrial frequency converter, first slide the two connecting blocks 311 on the rear side of the industrial frequency converter body 1 into the two connecting slots 31 through the top of the mounting base 211 and slide them downwards until the bottom of the two connecting blocks 311 contacts the bottom wall of the corresponding connecting slot 31. Then rotate the bolt 324, which drives the push block 325 to move downwards. During the downward movement of the push block 325, the sliding cooperation of the limiting slot 326 and the limiting block 327 pushes the moving block 321 closer to the limit. The industrial inverter body 1 moves to one side, causing the locking block 323 to approach the industrial inverter body 1 and insert into the locking groove 322, thereby completing the installation of the industrial inverter body 1. When disassembly is required, the bolt 324 is rotated in the opposite direction, the push block 325 moves upward, and the moving block 321 is reset through the cooperation of the limiting groove 326 and the limiting block 327. The locking block 323 exits from the locking groove 322 and slides into the mounting groove 32, so that the industrial inverter body 1 can be removed from the mounting base 211, realizing quick installation and disassembly.

[0023] When the industrial frequency converter body 1 is subjected to vibration, the vibration is quickly transmitted to the mounting base 211. The mounting base 211 then drives the transmission rod 225 to move, which in turn pushes the transmission plate 224 to move. During this process, the damper 222 uses its damping characteristics to resist the movement of the transmission plate 224. At the same time, the spring 223 generates a reverse elastic force due to compression or stretching. The two work together to buffer and disperse the vibration energy in the first stage, initially weakening the intensity of the vibration. Meanwhile, the movement of the transmission plate 224... The movement will drive the connecting plate 234 to move, and the connecting plate 234 will push the slider 232 to slide on the fixed rod 231. When the slider 232 slides, it will squeeze the disc spring 233. With its unique disc-shaped structure and elasticity, the disc spring 233 can efficiently absorb and disperse the remaining vibration energy. In conjunction with the damper 222 and the spring 223, the vibration received by the buffer seat 21 will be buffered and dispersed more fully, and the adverse effects of vibration on the industrial frequency converter body 1 will be reduced to the greatest extent, thereby effectively ensuring that the industrial frequency converter body 1 can always operate stably.
