Description

Technical Field

[0001] This utility model relates to the technical field of power distribution cabinet production equipment, and in particular to a lifting device for power distribution cabinet production. Background Technology

[0002] In the switchgear manufacturing industry, lifting equipment is one of the key pieces of equipment on the production line. It is responsible for safely and efficiently lifting the switchgear from the production station to a designated height, facilitating subsequent assembly, testing, and transportation processes. However, traditional switchgear lifting equipment has several design shortcomings that severely restrict production efficiency and operational safety.

[0003] Firstly, regarding stability, traditional lifting equipment generally employs simple support structures and lacks effective anti-rotation mechanisms. During lifting, the distribution cabinet is prone to swaying due to center of gravity shift or external forces, which can even lead to equipment overturning in severe cases, posing a serious threat to the production environment and operators. Furthermore, in some cases, due to wear and tear or improper maintenance during long-term use, the support structure loosens, further exacerbating instability during lifting.

[0004] Secondly, regarding safety, traditional lifting equipment mostly relies on manual operation and lacks intelligent monitoring and early warning systems. Operators need to manually control the lifting height and speed, which is not only cumbersome but also prone to causing safety accidents due to misoperation. At the same time, the equipment lacks self-diagnostic capabilities, making it difficult to detect and handle faults in a timely manner, increasing the risk of accidents. Therefore, we provide a lifting device for power distribution cabinet production. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a lifting device for the production of power distribution cabinets, which more accurately solves the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution:

[0007] The utility model proposes a lifting device for the production of power distribution cabinets, including a lifting mechanism and a horizontal support plate. The lifting mechanism includes a mounting frame, and the horizontal support plate is fixedly connected to the end of the mounting frame. A mounting groove is provided on one side surface of the horizontal support plate. A bottom support rod is rotatably connected to the inner wall of the mounting groove through a rotating shaft for supporting the bottom of the power distribution cabinet and lifting it. An anti-rotation component is connected between the horizontal support plate and the bottom support rod.

[0008] The anti-rotation assembly includes a strip groove on the other side surface of the horizontal support plate and a limiting insertion hole on the upper surface of the bottom support rod. A vertical support rod is fixedly connected between the two end walls of the strip groove. A spring is sleeved around the vertical support rod.

A connecting plate is fixedly connected to the end of the L-shaped frame. A limiting insertion rod is fixedly connected to the lower surface of the connecting plate. An anti-rotation structure is connected to the side of the L-shaped frame.

[0009] Furthermore, the anti-spin-out structure includes a connecting rod fixedly connected to the side of the L-shaped frame, and an L-shaped limiting plate is fixedly connected to the end side of the connecting rod to prevent the bottom rod from being screwed into the interior of the mounting groove and thus freely spinning out.

[0010] Furthermore, the lifting mechanism also includes a lower fixed frame and an upper fixed frame. Mounting plates are fixedly welded to the inner walls of both the lower and upper fixed frames. A threaded rod is rotatably connected to the mounting plate via a bearing. An n-shaped frame is fixedly mounted on the upper surface of the upper fixed frame. A servo motor is fixedly mounted on the upper end of the n-shaped frame, and the output end of the servo motor is fixedly connected to the upper end of the threaded rod. A threaded seat is threaded onto the outer periphery of the threaded rod, and the threaded seat is fixedly welded to the inner wall of the mounting frame. A guide slide component is connected between the lower and upper fixed frames.

[0011] Furthermore, the guide slide component includes a guide slide rod fixedly connected between the lower fixed frame and the upper fixed frame, and a guide slide seat is slidably sleeved around the guide slide rod, and the guide slide seat is fixedly connected to the side of the mounting bracket.

[0012] Furthermore, the limiting rod is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is compatible with the outer diameter of the limiting rod.

[0013] Furthermore, the upper end of the spring is fixedly connected to the end wall of the strip groove, and the lower end of the spring is fixedly connected to the upper surface of the sliding sleeve block.

[0014] The beneficial effects of this utility model are:

[0015] This invention effectively prevents the bottom rod from rotating and accidentally spinning out during the lifting process by designing a synergistic effect between the bottom rod and the anti-rotation component, as well as adding an anti-spin-out structure. At the same time, the design of the guide slide component further enhances the stability of the lifting process. These improvements together enhance the overall stability and safety of the lifting equipment, ensure the smooth operation of the power distribution cabinet during the lifting process, and reduce the safety risks caused by equipment failure or operational errors.

[0016] This invention achieves automated control of the lifting mechanism by using a servo motor to drive the rotation of the threaded rod. The servo motor has advantages such as high precision, fast response speed, and simple control, and can accurately control the height and speed of the lifting mechanism, thereby improving the working efficiency of the lifting equipment. In addition, the design of the lifting mechanism also considers stability and guiding function. Through the guidance of the guide slide component, the smoothness and accuracy of the lifting process are ensured. Attached Figure Description

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] like Figures 1-4As shown in the figure, an embodiment of this utility model discloses a lifting device for the production of power distribution cabinets, mainly including a lifting mechanism and a horizontal fixing plate 2. The core component of the lifting mechanism is the mounting frame 1, and the horizontal fixing plate 2 is firmly connected to one end of the mounting frame 1. A mounting groove 3 is designed on one side of the horizontal fixing plate 2, and a bottom support rod 4 is flexibly connected in the groove through a rotating shaft. The function of the bottom support rod 4 is to stably support the bottom of the power distribution cabinet during the lifting process. In order to prevent the bottom support rod 4 from rotating unnecessarily during the lifting process, an anti-rotation component is designed; the anti-rotation component consists of a strip groove 5, a vertical fixing rod 6, a spring 7, a sliding sleeve block 8, an L-shaped frame 9, a connecting plate 10, and a limiting plug 12. The strip groove 5 is opened on the other side of the horizontal fixing plate 2, the vertical fixing rod 6 is fixed between the two end walls of the strip groove 5, and the spring 7 is sleeved on the vertical fixing rod 6 to provide elastic force for the sliding sleeve block 8. The sliding sleeve block 8 can slide freely on the vertical fixing rod 6 and is connected to the connecting plate 10 through the L-shaped frame 9. The lower end of the connecting plate 10 is fixed with a limiting plug 12, which can be inserted into the limiting plug hole 11 at the upper end of the bottom support rod 4, thereby effectively preventing the bottom support rod 4 from rotating. Through the synergistic effect of the bottom support rod 4 and the anti-rotation component, the power distribution cabinet can remain stable during the lifting process, avoiding safety hazards caused by rotation.

[0024] Furthermore, an anti-spin-out structure was designed to enhance the stability of the bottom support rod 4. This structure includes a connecting rod 13 and an L-shaped limiting plate 14. The connecting rod 13 is fixedly connected to the side of the L-shaped frame 9, and the L-shaped limiting plate 14 is fixedly connected to the end side of the connecting rod 13. When the bottom support rod 4 is screwed into the mounting groove 3, the L-shaped limiting plate 14 prevents the bottom support rod 4 from freely spinning out, thereby further improving the stability and safety of the equipment. The anti-spin-out structure effectively prevents the bottom support rod 4 from accidentally spinning out during the lifting process, ensuring the stable operation of the equipment.

[0025] Furthermore, the lifting mechanism also includes a lower fixed frame 15 and an upper fixed frame 16, which are connected by a mounting plate 17 and a threaded rod 18. The threaded rod 18 rotates on the mounting plate 17 via bearings, while a servo motor 20 is fixedly mounted on an n-shaped frame 19 above the upper fixed frame 16. The output end of the servo motor 20 is connected to the upper end of the threaded rod 18, driving the threaded rod 18 to rotate and thus moving the threaded seat 21 up and down. The threaded seat 21 is fixedly welded to the inner wall of the mounting frame 1, thereby realizing the lifting function. To increase the stability during the lifting process, a guide slide component is also designed; the servo motor 20 drives the threaded rod 18 to rotate, realizing the smooth lifting of the mounting frame 1 and the power distribution cabinet, while the guide slide component further enhances the stability of the lifting process.

[0026] Furthermore, the guide slide component consists of a guide slide rod 22 and a guide slide seat 23. The guide slide rod 22 is fixedly connected between the lower fixed frame 15 and the upper fixed frame 16, while the guide slide seat 23 is slidably sleeved on the guide slide rod 22 and fixedly connected to the side of the mounting frame 1. The function of the guide slide component is to provide additional stability and guidance for the mounting frame 1 during the lifting process; the guide slide component effectively limits the swaying of the mounting frame 1 during the lifting process, improving the smoothness and accuracy of the lifting process.

[0027] Furthermore, the outer diameter of the limiting rod 12 is designed to match the inner diameter of the limiting hole 11, ensuring that the limiting rod 12 can be tightly inserted into the limiting hole 11, thereby effectively preventing the bottom rod 4 from rotating; through precise size matching, the connection between the limiting rod 12 and the limiting hole 11 is more stable and reliable, further improving the stability and safety of the equipment.

[0028] Furthermore, the upper end of the spring 7 is fixedly connected to the end wall of the strip groove 5, while the lower end is fixedly connected to the upper surface of the sliding sleeve block 8. The function of the spring 7 is to provide continuous elastic force to the sliding sleeve block 8, allowing it to fit tightly against the upright rod 6, and to push the limiting rod 12 into the limiting hole 11 when needed. The elastic force of the spring 7 ensures that the sliding sleeve block 8 and the limiting rod 12 can always remain in the correct position, thereby effectively preventing the bottom rod 4 from rotating or accidentally unspinning out.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
