Description
Technical Field
[0001] This utility model relates to the field of electromechanical equipment maintenance technology, and in particular to an electromechanical equipment maintenance platform. Background Technology
[0002] An electromechanical equipment maintenance bench is a professional platform used for the maintenance, repair, and testing of electromechanical equipment. It typically consists of basic components such as a base and a work surface, and some benches are also equipped with auxiliary devices such as clamping mechanisms and rotating mechanisms. The base provides stable support for the entire bench, while the work surface is used to place the electromechanical equipment to be inspected.
[0003] A search revealed Chinese patent application number CN202323131835.4, which discloses a maintenance platform for electromechanical equipment. This platform, primarily relating to electromechanical maintenance equipment, includes a base plate with telescopic rods installed at the four corners of its top surface. A horizontal plate is positioned between the top ends of the four telescopic rods. Two T-shaped grooves, distributed front to back, are formed on one side of the bottom surface of the horizontal plate. A T-shaped slider slides within each T-shaped groove, and the bottom surface of each T-shaped slider connects to a corresponding telescopic rod. This invention features a simple structure. By extending and retracting the telescopic rods, the height of the device can be adjusted to meet different height requirements. Furthermore, the cooperation between the T-shaped sliders and the T-shaped grooves allows the horizontal plate to be tilted, enabling maintenance of specific parts of the electromechanical equipment and improving maintenance efficiency. The cooperation of the guide rail and transmission seat allows the maintenance platform to move horizontally, reducing the need for maintenance personnel to walk.
[0004] The aforementioned patent mentions the beneficial effects: "By extending and retracting the telescopic rod, the height of the device can be adjusted to meet the usage needs at different heights. Simultaneously, with the cooperation of the T-shaped slider and T-shaped groove, the horizontal plate can be tilted, allowing for the maintenance of certain parts of the electromechanical equipment, thus improving the maintenance efficiency of maintenance personnel. Furthermore, with the cooperation of the guide rail and transmission seat, the maintenance platform can be moved horizontally, reducing the walking distance and physical labor of maintenance personnel, and bringing convenience to electromechanical maintenance." However, the structural design of adjusting height with a telescopic rod, achieving horizontal plate tilting with the cooperation of the T-shaped slider and groove, and driving the platform horizontally with the guide rail and transmission seat also has certain drawbacks. After long-term load-bearing extension and retraction, the telescopic rod may experience jamming or uneven lifting due to insufficient lubrication or component wear, affecting the accuracy of height adjustment. Although the cooperation of the T-shaped slider and groove can achieve tilting, the overall stability of the device decreases in the tilted state. If not securely fixed, slight shaking may occur during maintenance, interfering with the maintenance of precision components and even posing safety hazards. Therefore, an electromechanical equipment maintenance platform is proposed to solve the above problems. Utility Model Content

[0015] 1. This utility model discloses a mechanical and electrical equipment maintenance platform.

The sliding block two at the other end of the connecting rod slides inside the limiting plate, achieving height adjustment. The height of the work surface can be flexibly adjusted according to the size and weight of the mechanical and electrical equipment to be maintained, as well as the operating habits of the maintenance personnel. This allows workers to work comfortably without bending over, tiptoeing, or frequently adjusting their posture, effectively reducing physical fatigue from prolonged maintenance and lowering the risk of occupational injuries such as lumbar muscle strain. Simultaneously, by adjusting the height, the maintenance parts of the equipment can be placed in the most convenient position for observation and operation. Whether disassembly, installation, or testing, it can be carried out more easily and efficiently. Especially for large or heavy mechanical and electrical equipment, there is no need for manual handling to adjust the height, saving physical strength, improving maintenance efficiency, and avoiding equipment damage or personnel injury due to improper handling, further ensuring the safety of the maintenance process.

Detailed Implementation
[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] Reference Figures 1 to 3 This utility model provides an embodiment of an electromechanical equipment maintenance platform, including an operating platform 1. An adaptive clamping mechanism 2 is installed inside the operating platform 1. The operating platform 1 provides installation space and support foundation for the adaptive clamping mechanism 2 to ensure stable operation of the clamping mechanism. A lifting mechanism 3 is installed on the inner wall of the operating platform 1. The inner wall of the operating platform 1 provides an installation carrier for the lifting mechanism 3 to ensure that the components of the lifting mechanism 3 work together. A baffle 4 is fixedly connected to the top of the operating platform 1. The baffle 4 blocks the equipment or tools on the surface of the operating platform 1 to prevent items from slipping during maintenance and enhances the safety of the operating platform 1.
[0025] The adaptive clamping mechanism 2 includes a square box 21, which is the main frame of the adaptive clamping mechanism 2, providing installation space and support for components such as cylinder 22 and transmission plate 23. The outer wall of the square box 21 is slidably connected to the inside of the operating table 1, and its position can be adjusted along the operating table 1, so that the clamping mechanism can adapt to the maintenance needs of different positions and enhance the operational flexibility. Cylinder 22 is fixedly connected to the inner wall of the square box 21, and the square box 21 provides a stable installation base for the cylinder to ensure stable output power of the cylinder. Cylinder 22 serves as the power source of the clamping mechanism and is a subsequent transmission component. The drive end of cylinder 22 is fixedly connected to the transmission plate 23, which converts the power of the cylinder into the linear motion of the transmission plate 23.
[0026] Multiple transmission rods 24 are rotatably connected to the inner wall of the transmission plate 23. The movement of the transmission plate 23 drives the transmission rods 24 to rotate, converting linear motion into rotational motion. Multiple connecting plates 25 are rotatably connected to the outer wall of the multiple transmission rods 24. The rotational motion of the transmission rods 24 drives the connecting plates 25 to move, realizing the transmission of power. Sliding blocks 26 are fixedly connected to the top of the multiple connecting plates 25. The movement of the connecting plates 25 drives the sliding blocks 26 to move synchronously. The sliding blocks 26 provide a mounting base for the reset assembly 27 and drive its movement. The reset assembly 27 is fixedly connected to the top of the multiple sliding blocks 26. The movement of the sliding blocks 26 drives the reset assembly 27 to move. After the clamping action is completed, the reset assembly 27 can drive the relevant components to reset, preparing for the next clamping.
[0027] Reference Figures 1 to 3 The reset assembly 27 includes multiple mounting plates 271. The reset assembly 27 is based on these mounting plates 271, which provide mounting support for guide rods 272, springs 273, etc. The bottom ends of the multiple mounting plates 271 are fixedly connected to the top end of a connecting plate 25. The connecting plate 25 drives the mounting plates 271, causing the reset assembly 27 to be linked with the clamping action, ensuring that the reset timing matches the clamping action. Guide rods 272 are slidably connected to the inner walls of the multiple mounting plates 271. The guide rods 272 provide precise guidance for the sliding of the mounting plates 271, limiting their direction of movement. Together, these elements ensure that the mounting plates 271 are smoothly reset under the action of the springs 273, preventing displacement.
[0028] Springs 273 are fitted on the outer walls of multiple guide rods 272, providing a telescopic track for the springs 273 and preventing them from twisting or deforming. Fixed rods 274 are fixedly connected to the top of multiple connecting plates 25. The connecting plates 25 drive the fixed rods 274 to move synchronously with the connecting plates 25. The fixed rods 274 provide a rotation fulcrum for the V-shaped plate 275 and are the support structure for the V-shaped plate 275 to perform clamping actions. V-shaped plates 275 are rotatably connected to the outer walls of multiple fixed rods 274. The V-shaped plates 275 can rotate flexibly around the fixed rods 274. The V-shaped plates 275 can adjust the clamping angle by rotating to adapt to workpieces of different shapes and achieve adaptive clamping. Fixed plates 276 are fixedly connected to the outer walls of multiple guide rods 272. The fixed plates 276 limit one end of the spring 273, so that the elastic force generated when the spring 273 is compressed can be accurately applied to the mounting plate 271.
[0029] Reference Figures 2 to 4The lifting mechanism 3 includes multiple limiting plates 31. The lifting mechanism 3 is based on the multiple limiting plates 31 as basic support components. The limiting plates 31 provide a stable bottom support for the entire mechanism, ensuring the structural stability of components such as the connecting rod 32 when they move. They are the basic support for realizing the lifting function. The bottom ends of the multiple limiting plates 31 are fixedly connected to the inner wall of the operating platform 1. The operating platform 1 provides a solid installation base for the limiting plates 31, so that the limiting plates 31 do not shift when bearing load, ensuring the overall stability of the lifting mechanism 3. The top ends of the multiple limiting plates 31 are rotatably connected to the connecting rod 32. The limiting plates 31 provide a rotation fulcrum for the connecting rod 32, allowing the connecting rod 32 to rotate flexibly around the limiting plates 31, providing the necessary rotational freedom for the lifting action, and are the key nodes for force transmission.
[0030] Two connecting rods 32 are rotatably connected to adjacent sides of each other. The connecting rods 33 connect the paired connecting rods 32 into a scissor-like structure, making the movement of the connecting rods 32 synchronized and coordinated, while enhancing the connection strength between the connecting rods 32 and ensuring uniform force transmission. One of the connecting rods 33 has a fixing block 34 fixedly connected to its outer wall. The fixing block 34 provides a mounting carrier for the cylinder 35 and transmits the driving force of the cylinder to the connecting rod 33. It is a connecting component for power input. The fixing block 34 has a cylinder 35 fixedly connected to its outer wall. The fixing block 34 provides a stable mounting position for the cylinder 35 and ensures that the driving force output by the cylinder 35 can effectively act on the connecting rod 33. It is the power source mounting foundation for the lifting mechanism 3. The driving end of cylinder 2 35 is fixedly connected to a fixing block 2 36. The fixing block 2 36 converts the extension and retraction motion of the cylinder into a pushing or pulling force on the connecting rod 33, realizing the effective transmission of power. It is a bridge connecting the cylinder and other components. The other end of multiple connecting rods 32 is slidably connected to a sliding block 2 37. The sliding block 2 37 provides a sliding fulcrum for the end of the connecting rod 32, so that the connecting rod 32 can move along a certain trajectory when rotating. It cooperates with the rotation of the connecting rod 32 to realize the lifting action and ensures that the lifting process is smooth and stable.
[0031] Reference Figures 2 to 4The outer wall of the connecting plate 25 is slidably connected to the inner wall of the square box 21. The square box 21 provides a sliding track for the connecting plate 25, restricting its movement to only a specific direction, ensuring that the connecting plate 25 moves smoothly under the drive of the transmission rod 24, and ensuring the accuracy of the clamping action. The outer walls of multiple V-shaped plates 275 are in contact with the adjacent side of multiple guide rods 272. The guide rods 272 provide support and limit for the V-shaped plates 275. When the V-shaped plates 275 clamp the workpiece, the guide rods 272 restrict its excessive rotation through contact, and at the same time cooperate with the spring 273 to achieve adaptive adjustment. One end of the spring 273 is fixedly connected to the outer wall of the mounting plate 271, and the other end of the spring 273 is fixedly connected to the outer wall of the fixing plate 276. One end of the spring 273 is fixed to the outer wall of the mounting plate 271, and the other end is fixed to the outer wall of the fixing plate 276, forming an elastic connection structure. When the mounting plate 271 moves with the connecting plate 25, the spring 273 is compressed to generate elastic force, providing power for the reset of each component.
[0032] The outer walls of multiple sliding blocks 37 are slidably connected to the inner walls of multiple limiting plates 31. The limiting plates 31 provide sliding guidance for the sliding blocks 37, allowing them to move along a fixed trajectory as the connecting rod 32 moves, ensuring smooth and orderly lifting actions. The inner walls of fixed blocks 36 are rotatably connected to the outer walls of the connecting rod 33. Fixed blocks 36 can rotate with the connecting rod 33, ensuring that the driving force of cylinder 35 can be flexibly transmitted to the connecting rod 33, avoiding motion interference. The tops of the two limiting plates 31 are fixedly connected to the bottom of the square box 21, providing support for the square box 21 and connecting the lifting mechanism 3 to the adaptive clamping mechanism 2, so that the lifting action can synchronously drive the clamping mechanism to adjust the height. The inner walls of the limiting plates 31 open... A sliding groove is provided on the inner wall of the limiting plate 31. The sliding groove provides sliding space for the second sliding block 37, restricts its movement direction, and ensures that the second sliding block 37 slides smoothly along the sliding groove under the drive of the connecting rod 32, thus ensuring the normal operation of the lifting mechanism 3. A sliding groove is also provided on the inner wall of the square box 21. The sliding groove provides a sliding track for the first sliding block 26 and the connecting plate 25, ensuring that they move in a fixed direction during transmission and avoiding deviation that affects the clamping accuracy. The outer wall of the first sliding block 26 is slidably connected to the inner wall of the square box 21. The square box 21 restricts the movement trajectory of the first sliding block 26 through the sliding groove, so that the first sliding block 26 moves smoothly and synchronously with the connecting plate 25, thus ensuring the normal operation of the reset assembly 27.
[0033] Working principle: When clamping electromechanical equipment is required, the square box 21 slides within the operating table 1 to provide an adjustment base. The cylinder 22 drives the transmission plate 23 to move, which in turn drives multiple transmission rods 24 to rotate. The transmission rods 24 push the connecting plate 25 and the sliding block 26 to move. The connecting plate 25 drives the V-shaped plate 275 on the fixed rod 274 to move, causing the V-shaped plate 275 to move towards the center to clamp the workpiece. At the same time, the guide rod 272 slides inside the mounting plate 271 due to the compression of the V-shaped plate 275. The spring 273 is limited and compressed by the fixed plate 276. When the workpiece is released, the spring 273 pushes the V-shaped plate 275 to reset, realizing adaptive clamping and reset of workpieces of different sizes.
[0034] When the square box 21 needs to be raised or lowered, multiple limiting plates 31 provide stable support by fixing their bottom ends to the inner wall of the operating table 1, and their top ends provide a fulcrum for the connecting rod 32. When the cylinder 2 35 extends or retracts, it drives the connected connecting rod 33 to move through the fixing block 1 34. At the same time, the fixing block 2 36 at the drive end pulls another connecting rod 33, causing the pair of connecting rods 32 to rotate around the top of the limiting plate 31 and form a scissor-like linkage. The sliding block 2 37 at the other end of the connecting rod 32 slides along the sliding groove on the inner wall of the limiting plate 31, and the height is adjusted in conjunction with the rotation of the connecting rod 32. When the cylinder 2 35 extends, the angle of the connecting rod 32 increases, pushing the load to rise. When it shortens, the angle decreases, driving the load to fall. Through the coordinated action of each component, a stable lifting function is achieved to meet different maintenance height requirements.

Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
