Description

Technical Field

[0001] This invention belongs to the field of mechanical component support technology, specifically relating to an electromechanical maintenance support mechanism with flexibly adjustable dimensions. Background Technology

[0002] Electromechanical maintenance refers to the maintenance work performed on some components of electromechanical equipment during long-term operation in order to ensure the continuous and safe use of the equipment. This facilitates the normal operation of subsequent work. In order to facilitate the maintenance of components, they are usually placed on support devices for support, so as to better facilitate various maintenance operations. Therefore, electromechanical maintenance support devices are needed.

[0003] Chinese invention patent CN221985045U discloses an electromechanical maintenance support mechanism, including a workbench. A fixed plate is fixedly connected to one side of the upper surface of the workbench, and a motor is fixedly connected to one side of the fixed plate. One end of the motor's output shaft passes through the fixed plate and is keyed to a second rotating disk. Two sliding rods are fixedly connected to one side of the fixed plate, and a movable plate is slidably connected to the two sliding rods. An adjustment assembly is provided between the movable plate and the workbench. A first rotating disk is rotatably connected to one side of the movable plate, and two mounting plates are fixedly connected to one side of both the first and second rotating disks. This invention not only allows the equipment to be rotated, increasing the operator's operating range and facilitating equipment maintenance, but also eliminates the need for operators to move with the equipment, increasing work efficiency. Furthermore, the position of the movable plate can be fixed via the adjustment assembly, allowing for the fixing of equipment of different sizes.

[0004] However, the aforementioned patent utilizes the interplay of multiple sockets and pins to maintain devices of different sizes. During maintenance, first pull out the pin and then push the moving plate to move the moving plate along the slide bar; and simply fix the angle of the rotated equipment by the cooperation of the slot and the lever; all of the above methods need to be done manually, which is time-consuming and labor-intensive, and has problems such as inaccuracy. Summary of the Invention

[0005] In view of the above-mentioned shortcomings in the prior art, the present invention provides an electromechanical maintenance support mechanism with flexibly adjustable size to solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An electromechanical maintenance support mechanism with adjustable dimensions includes a base, a movable plate, and a fixed plate; The movable plate and the fixed plate are arranged opposite to each other, and the opposite sides are respectively connected to the mounting components through the first rotating rod and the second rotating rod, which are used to fix the electromechanical equipment to be repaired. The base is provided with a first slide rail, and the bottom of the movable plate is provided with a first slide groove. The movable plate slides in conjunction with the first slide rail through the first slide groove. The base is also provided with an adjustment assembly, including a first motor, a lead screw connected to the output end of the first motor, and a ball nut sleeved on the lead screw and fixedly connected to the groove at the bottom of the moving plate; The fixing plate is fixed to the base, and a rotating assembly is installed on the fixing plate, including a second motor, a worm gear connected to the output end of the second motor, and a turbine gear meshing with the worm gear; the turbine gear is fixedly connected to a second rotating rod, and a gear shaft is fixedly connected to the second rotating rod; the bottom of the gear shaft is connected to a locking assembly.

[0007] Furthermore, the mounting assembly includes a mounting block and a fixing block; the mounting block is fixedly connected to the opposing ends of the first rotating rod and the second rotating rod respectively; the fixing block is detachably connected to the bottom of the mounting block, and the fixing block is provided with a threaded hole.

[0008] Furthermore, the end of the first rotating rod away from the mounting block is rotatably connected to the movable plate, and the end of the second rotating rod away from the mounting block is rotatably connected to the fixed plate.

[0009] Furthermore, the fixing plate is provided with a mounting groove, and the locking component is placed in the mounting groove.

[0010] Furthermore, the locking assembly includes a cylinder and a locking element fixedly connected to the output end of the cylinder's telescopic rod.

[0011] Furthermore, the top of the locking element is provided with an internal gear that can mesh with the gear shaft.

[0012] Furthermore, a second sliding groove is provided on both sides of the locking member, and a second sliding rail is correspondingly provided on the side wall of the mounting groove.

[0013] Furthermore, it also includes a PLC controller, and the first motor, the second motor, and the cylinder are all electrically connected to the PLC controller.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The adjustment assembly, consisting of a servo motor and a lead screw nut, can drive the moving plate to move continuously along the slide rail, achieving precise and continuous adjustment of the distance between the moving plate and the fixed plate. It can adapt to electromechanical equipment of different lengths and specifications. Moreover, the adjustment process is automatically controlled by the PLC controller, which greatly shortens the adjustment time and improves the equipment fixing efficiency.

[0015] The rotating component uses a worm gear drive, which can drive the equipment to rotate slowly and smoothly, meeting the needs of multi-directional maintenance operations and preventing the equipment from shaking due to excessive rotation. In conjunction with the gear meshing and locking structure of the locking component, after the equipment rotates to the target angle, the cylinder drives the locking part to quickly mesh with the gear shaft. The self-locking characteristic of the gear ensures that the equipment is stably fixed and prevents angular displacement due to external force or gravity during maintenance.

[0017] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this application. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Example 1: like Figure 1-3 As shown, this invention provides a flexible, adjustable electromechanical maintenance support mechanism. The support mechanism can be flexibly adjusted according to the electromechanical component to be repaired. Its main structure consists of a base 1, a movable plate 2, and a fixed plate 3. It also includes an adjustment component 4 for driving the movable plate 2; a mounting component 5 for mounting the electromechanical component to be repaired; a rotating component 33 for adjusting the angle of the mounting component 5; and a locking component 6 for fixing the rotating component 33.

[0022] Specifically, such as Figure 1-2As shown, the base 1 is a rectangular metal plate, serving as the supporting foundation for the entire support mechanism. Two parallel first slide rails 11 are symmetrically arranged along its length on its top to guide the sliding of the moving plate 2. The base 1 can be selectively placed on a lifting platform or other workbench for convenient operation. A fixed plate 3 is fixedly mounted on one end of the base 1, and the other end is connected to the moving plate 2 via an adjusting assembly 4, allowing the moving plate 2 and fixed plate 3 to be positioned opposite each other. The distance between them can be adjusted to accommodate equipment of different lengths. The moving plate 2 is slidably connected to the base 1, and its bottom has a first slide groove 22 that matches the first slide rails 11. Through the sliding cooperation of the first slide groove 22 and the first slide rails 11, the moving plate 2 can smoothly move along the length of the base 1. A groove 21 is also provided in the center of the bottom of the moving plate 2 for fixed connection with the adjusting assembly 4, ensuring stable transmission of the adjusting force. The fixed plate 3 is fixedly connected to the base 1, and its central part has a mounting groove 31 for accommodating the locking assembly 6. Second slide rails 311 are provided on both sides of the mounting groove 31 to guide the locking assembly 6.

[0023] Mounting component 5 is the part that directly contacts the electromechanical device to be maintained, used to securely fix the equipment. It is symmetrically arranged on the opposite side of the moving plate 2 and the fixed plate 3, and includes a mounting block 51 and a fixing block 52. Mounting block 51 is a metal block structure, welded and fixed to the opposite ends of the first rotating rod 23 and the second rotating rod 34, forming symmetrical support points to ensure balanced force on the equipment. Fixing block 52 is detachably connected to the bottom of mounting block 51 by bolts. Its surface has multiple evenly distributed threaded holes 53, which can be used with bolts or clamps to fix electromechanical devices of different sizes. The detachable design facilitates replacement of fixing blocks 52 of different specifications according to equipment characteristics. One end of the first rotating rod 23 is rotatably connected to the moving plate 2 via a bearing, and the other end is fixedly connected to the mounting block 51. One end of the second rotating rod 34 passes through the fixed plate 3 and is fixedly connected to the turbine 333, and the other end is fixedly connected to the mounting block 51. Its middle part is rotatably connected to the fixed plate 3, which provides support.

[0024] The adjustment component 4 is the core component for flexible size adjustment. It is used to drive the movable plate 2 to translate, thereby adjusting the distance between the movable plate 2 and the fixed plate 3 to adapt to electromechanical equipment of different lengths. Specifically, it includes a first motor 41, a lead screw 42, and a ball nut 43. The first motor 41 is a servo motor, which is fixedly installed at the end of the base 1 away from the fixed plate 3. It is connected to the PLC controller through wires and can flexibly control the speed and direction. The lead screw 42 is set along the length of the base 1. One end of it is fixedly connected to the output end of the first motor 41 through a coupling, and the other end is rotatably connected to the fixed plate 3 through a bearing seat to form a stable transmission support. The ball nut 43 is sleeved on the lead screw 42 and threadedly engaged with the lead screw 42. Its top is welded and fixed to the groove 21 at the bottom of the movable plate 2, converting the rotational motion of the lead screw 42 into linear motion. When size adjustment is required, the PLC controller controls the first motor 41 to start, driving the lead screw 42 to rotate forward or reverse. The ball nut 43 moves axially along the lead screw 42, causing the moving plate 2 to slide along the first slide rail 11 through the first slide groove 22, thereby realizing continuous adjustment of the distance between the moving plate 2 and the fixed plate 3. This meets the fixing requirements of equipment of different sizes, eliminating the need for manual pushing or inserting and removing positioning pins, and greatly improving adjustment efficiency.

[0025] The rotating assembly 33 is mounted on the fixed plate 3 and is used to drive the second rotating rod 34 and the mounting assembly 5 to rotate, enabling flexible adjustment of the equipment maintenance angle. Specifically, it includes a second motor 331, a worm gear 332, and a turbine 333. The second motor 331 is a stepper motor, fixed to the side of the fixed plate 3, and connected to a PLC controller via wires, allowing for flexible control of the rotation angle. One end of the worm gear 332 is fixedly connected to the output end of the second motor 331, and the other end is rotatably connected to the fixed plate 3 via a bearing, transmitting rotational power. The turbine 333 is sleeved on the second rotating rod 34 and keyed to it, meshing with the worm gear 332 to form a worm gear transmission structure. Utilizing its large transmission ratio and smooth operation, it achieves slow rotation of the equipment, preventing equipment shaking due to excessive rotation. When the equipment angle needs to be adjusted, the PLC controller controls the second motor 331 to start, driving the worm gear 332 to rotate. The worm gear 332 drives the turbine 333 and the second rotating rod 34 to rotate synchronously, thereby driving the equipment to rotate through the mounting assembly 5. Since the first rotating rod 23 is rotatably connected to the moving plate 2, the first rotating rod 23 rotates passively with the equipment when the equipment rotates, ensuring that the mounting assemblies 5 on both sides move synchronously and avoiding the equipment from twisting due to force on one side.

[0026] like Figure 3As shown, the locking assembly 6 is housed in the mounting groove 31 of the fixed plate 3. It is used to lock the second rotating rod 34 after the equipment is rotated to the target angle, ensuring the stability of the equipment during maintenance. Specifically, it includes a cylinder 61 and a locking component 62. The cylinder 61 is vertically fixed to the bottom of the mounting groove 31, with its telescopic rod facing upward. By connecting to the PLC controller, the extension and retraction of the telescopic rod can be quickly controlled. The locking component 62 is a block-shaped structure with an internal gear at the top. Its bottom is fixedly connected to the top of the telescopic rod of the cylinder 61. It has second sliding grooves 621 on both sides that match the second sliding rail 311 on the side wall of the mounting groove 31. Through the sliding cooperation between the second sliding groove 621 and the second sliding rail 311, the locking component 62 is restricted to move only in the vertical direction, ensuring that the internal gear and the gear shaft 32 mesh precisely. Once the equipment rotates to the target angle, the PLC controller automatically controls the extension rod of cylinder 61 to extend, pushing the locking member 62 upward along the second slide rail 311. This causes the internal gear at the top of the locking member 62 to mesh with the gear shaft 32 on the second rotating rod 34. The self-locking characteristic of the gear transmission locks the second rotating rod 34, preventing it from rotating under the weight of the equipment or external forces. When the angle needs to be adjusted again, the extension rod of cylinder 61 is retracted, the locking member 62 moves downward, the internal gear disengages from the gear shaft 32, and the lock is released. The operation is convenient and the locking is reliable.

[0027] This mechanism also includes a PLC controller (not shown in the figure), which is electrically connected to the first motor 41, the second motor 331 and the cylinder 61 respectively to realize automated control, greatly reduce manual operation steps and improve maintenance efficiency.
