Description
Technical Field
[0001] This utility model relates to the field of handling auxiliary equipment technology, specifically a lifting device for SVG modules. Background Technology
[0002] As a core device for dynamic reactive power compensation in power systems, SVG plays a crucial role in grid voltage stabilization, harmonic suppression, and power quality improvement. The handling and lifting of SVG modules is a key aspect of the installation, maintenance, and replacement of SVG equipment.
[0003] In the prior art, such as Chinese Patent Publication No. CN223002672U, a lifting device for SVG modules is disclosed, comprising: a base plate; a base, which is disposed above the base plate for placing the SVG module; a lifting part, disposed between the base plate and the base, the lifting part including a power component and a retractable lifting bracket, the two ends of the lifting bracket being connected to the base plate and the base respectively, the power component being used to drive the lifting bracket to extend and retract; and a conveying part, which is disposed above the base and extends along the length of the base, the conveying part including multiple rotating rollers arranged side by side, and the rotating rollers being rotatably disposed on the base. This can effectively reduce the physical burden on operators, reduce the possibility of safety accidents and equipment damage caused by SVG modules falling during manual handling, speed up the loading and unloading of SVG modules, and is convenient, quick, time-saving, and labor-saving, improving work efficiency and accuracy.
[0004] Although the above technical solution has the above technical advantages, its disadvantage is that the rotating roller in the solution only has the function of assisting in pushing the SVG module and cannot achieve locking and fixing. When the device is moved as a whole in a narrow space or when lifting is carried out through the lifting bracket, the rotating roller is prone to unexpected rotation due to external disturbance, which may cause the SVG module placed on it to shift or even slip off. There is still a risk of equipment damage and safety accidents, and it cannot meet the stable protection requirements for the transfer of heavy modules. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a lifting device for SVG modules, which solves the problem of easy displacement of SVG modules during transportation.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a lifting device for an SVG module, comprising a base plate, a locking universal wheel fixedly installed at the bottom of the base plate, a guide frame fixedly connected to the top of the base plate, a drive motor fixedly connected to the top of the guide frame, a lead screw fixedly connected to the output end of the drive motor, and further comprising: a support assembly, the outer side of the support assembly being slidably connected to the inner side of the guide frame, and the device being moved as a whole by means of the locking universal wheel fixedly installed at the bottom of the base plate;
[0007] The support assembly includes a lifting frame, with a roller rotatably connected to the inner side of the lifting frame and a sliding plate slidably connected to the inner side of the lifting frame. A friction plate is fixedly connected to the top of the sliding plate, and a limit block is fixedly connected to the bottom of the sliding plate. A threaded rod is rotatably connected to the inner side of the lifting frame, and a sliding frame is threadedly connected to the outer side of the threaded rod. When the roller can rotate freely, the operator can easily push the SVG module from the roller to the target area of the placement frame, thereby completing the transfer or replacement installation operation.
[0008] Preferably, a corrugated sleeve is provided on the outer side of the lead screw. The bottom end of the corrugated sleeve is fixedly connected to the top of the lifting frame, and the top end of the corrugated sleeve is fixedly connected to the inner side of the guide frame. The corrugated sleeve extends and retracts synchronously with the lifting frame, which can effectively prevent dust and debris in the narrow space from entering the threaded transmission structure of the lead screw and the lifting frame, ensuring transmission stability and service life.
[0009] Preferably, the outer side of the lifting frame is slidably connected to the outer side of the guide frame, and the inner wall of the lifting frame is threadedly connected to the outer wall of the lead screw. When the lead screw rotates, the guide frame provides vertical guidance and limit for the lifting frame. At this time, the rotational motion of the lead screw is converted into the linear lifting motion of the lifting frame along the inner side of the guide frame.
[0010] Preferably, the idler roller and the friction plate are arranged linearly along the inner side of the lifting frame, and the idler roller is located directly above the lifting frame. When the friction plate is in close contact with the idler roller, the rotational freedom of the idler roller is restricted by the friction between the friction plate and the idler roller, thereby locking the idler roller.
[0011] Preferably, the inner wall of the sliding frame is slidably connected to the inner side of the lifting frame via a guide rod. The sliding frame is located at the bottom of the sliding plate, and the rotational motion of the threaded rod can be converted into linear movement of the sliding frame along the direction of the guide rod.
[0012] Preferably, the two sides of the sliding frame are slidably connected to the inner wall of the limiting block through a sliding groove, and the sliding groove is opened in the inner wall of the limiting block. Because the sliding groove is opened at an inclination in the inner wall of the limiting block, when the sliding frame moves, the sliding of its two sides in the inclination sliding groove will generate an upward pushing force, which will lift up the limiting block that is fixedly connected to the bottom of the sliding plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] (i) By setting up a support component, the device achieves the dual functions of stable support and anti-displacement locking of the SVG module. The roller in the support component can help the staff to easily push the heavy SVG module by taking advantage of its rotation characteristics, reducing the difficulty of placement in confined spaces. At the same time, through the coordinated linkage of the roller, friction plate, threaded rod, sliding frame, limit block and inclined slide, the roller can be easily locked and unlocked, preventing the SVG module from being displaced or slipping due to the rotation of the roller during transportation or lifting, thus improving the safety and stability of module handling.
[0015] (ii) The device forms a stable lifting transmission structure by means of a lead screw, a drive motor, and a lifting frame. Under the guiding and limiting action of the guide frame, the rotational motion of the drive motor can be smoothly converted into the linear lifting motion of the lifting frame, which drives the support components and SVG modules to freely adjust their height to meet the needs of different heights of the placement rack area, thereby improving the adaptability and work efficiency of SVG module replacement and maintenance in confined spaces.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figure 1-4This utility model provides a technical solution: a lifting device for an SVG module, including a base plate 1, with locking casters 2 fixedly installed at the bottom of the base plate 1, a guide frame 3 fixedly connected to the top of the base plate 1, a drive motor 4 fixedly connected to the top of the guide frame 3, and a lead screw 5 fixedly connected to the output end of the drive motor 4. It also includes a support assembly 7, with the outer side of the support assembly 7 slidably connected to the inner side of the guide frame 3; a corrugated sleeve 6 is provided on the outer side of the lead screw 5, with the bottom end of the corrugated sleeve 6 fixedly connected to the top of a lifting frame 71, and the top end of the corrugated sleeve 6 fixedly connected to the inner side of the guide frame 3. After the SVG module is placed, it is pushed by the locking casters 2 fixedly installed at the bottom of the base plate 1. Once the entire unit moves to the preset position, the drive motor 4 is activated according to the height requirements of the placement area. The output of the drive motor 4 drives the lead screw 5 to rotate. The guide frame 3 provides vertical guidance and limit for the lifting frame 71. At this time, the rotational motion of the lead screw 5 is converted into the linear lifting motion of the lifting frame 71 along the inner side of the guide frame 3, which in turn drives the support component 7 and the SVG module to rise and fall together until the target height position is reached, at which point the drive motor 4 stops rotating. During this process, the corrugated sleeve 6 on the outer side of the lead screw 5 extends and retracts synchronously with the lifting frame 71, which can effectively prevent dust and debris in the narrow space from entering the threaded transmission structure of the lead screw 5 and the lifting frame 71, ensuring transmission stability and service life.
[0023] The supporting assembly 7 includes a lifting frame 71, with a roller 72 rotatably connected to the inner side of the lifting frame 71, a sliding plate 73 slidably connected to the inner side of the lifting frame 71, a friction plate 74 fixedly connected to the top of the sliding plate 73, and a limit block 77 fixedly connected to the bottom of the sliding plate 73. A threaded rod 75 is rotatably connected to the inner side of the lifting frame 71, and a sliding frame 76 is threadedly connected to the outer side of the threaded rod 75. The outer side of the lifting frame 71 is slidably connected to the outer side of the guide frame 3. The inner wall of the lifting frame 71 is threadedly connected to the outer wall of the lead screw 5. The roller 72 and the friction plate 74 are both linearly arranged along the inner side of the lifting frame 71, with the roller 72 located directly above the lifting frame 71. The inner wall of the sliding frame 76 is connected to the inner side of the lifting frame 71 via a guide rod. The sliding frame 76 is located at the bottom of the sliding plate 73. The two sides of the sliding frame 76 are slidably connected to the inner wall of the limiting block 77 through the sliding groove 78. The sliding groove 78 is opened in the inner wall of the limiting block 77. The threaded rod 75 is manually driven to rotate by the knob. At this time, the rotational motion of the threaded rod 75 is converted into the linear movement of the sliding frame 76 along the direction of the guide rod. Since the sliding groove 78 is inclined in the inner wall of the limiting block 77, when the sliding frame 76 moves, the sliding of its two sides in the inclined sliding groove 78 will generate an upward pushing force, which will lift the limiting block 77 which is fixedly connected to the bottom of the sliding plate 73, and simultaneously drive the sliding plate 73 to slide upward along the inner side of the lifting frame 71, and finally push the friction plate 74 to make close contact with the roller 72. The friction between the friction plate 74 and the idler roller 72 restricts the rotational freedom of the idler roller 72, thereby locking the idler roller 72 and fixing the position of the SVG module placed on top of the idler roller 72 to prevent displacement during subsequent movement. When it is necessary to remove the SVG module from the device, the reverse drive threaded rod 75 rotates, causing the sliding frame 76 to move in the opposite direction. The pushing force of the sliding frame 76 on the limiting block 77 disappears, and the sliding plate 73 and the limiting block 77 reset under their own gravity. The friction plate 74 separates from the idler roller 72, and the idler roller 72 returns to a state of free rotation. At this time, the operator can easily push the SVG module from the idler roller 72 to the target area of the placement frame, thereby completing the transfer or replacement installation operation.
[0024] Working principle: When in use, the operator places the heavier SVG module on top of the idler roller 72 of the support component 7;
[0025] Then, the threaded rod 75 is manually driven to rotate via a knob. This rotational motion of the threaded rod 75 is converted into linear movement of the sliding frame 76 along the guide rod. Because the slide groove 78 is inclined within the inner wall of the limiting block 77, the sliding of the sliding frame 76 within the inclined slide groove 78 generates an upward pushing force, lifting the limiting block 77, which is fixedly connected to the bottom of the sliding plate 73. Simultaneously, this causes the sliding plate 73 to slide upwards along the inner side of the lifting frame 71, ultimately pushing the friction plate 74 into close contact with the idler roller 72. The friction between the friction plate 74 and the idler roller 72 restricts the rotational freedom of the idler roller 72, locking it in place and thus fixing the SVG module positioned on top of the idler roller 72, preventing displacement during subsequent movements.
[0026] After the SVG module is placed, the locking casters 2 fixedly installed at the bottom of the base plate 1 push the entire device to move. After reaching the preset position, the drive motor 4 is started according to the height requirements of the placement area. The output end of the drive motor 4 drives the lead screw 5 to rotate. The guide frame 3 plays a vertical guiding and limiting role for the lifting frame 71. At this time, the rotational motion of the lead screw 5 is converted into the linear lifting motion of the lifting frame 71 along the inner side of the guide frame 3, which in turn drives the support component 7 and the SVG module to rise and fall together until the target height position is reached, after which the drive motor 4 stops rotating. During this process, the corrugated sleeve 6 on the outer side of the lead screw 5 extends and retracts synchronously with the lifting frame 71, which can effectively prevent dust and debris in the narrow space from entering the threaded transmission structure of the lead screw 5 and the lifting frame 71, ensuring transmission stability and service life.
[0027] When the SVG module needs to be removed from the device, the reverse drive threaded rod 75 rotates, causing the sliding frame 76 to move in the opposite direction. The pushing force of the sliding frame 76 on the limiting block 77 disappears, and the sliding plate 73 and the limiting block 77 reset under their own gravity. The friction plate 74 separates from the idler roller 72, and the idler roller 72 returns to its free rotation state. At this time, the operator can easily push the SVG module from the idler roller 72 to the target area of the placement frame, thereby completing the transfer or replacement installation operation.
