Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, specifically an intelligent lifting machine. Background Technology

[0002] Elevators are used in construction, decoration, and road construction. They can lift people to a certain height to meet construction requirements and are quite convenient. However, construction workers usually place the necessary construction materials on the platform, which can easily cause uneven weight distribution on both sides of the platform, resulting in tilting and posing a safety hazard.

[0003] To address the aforementioned technical issues, Chinese patent CN222389532U describes a high-altitude lifting platform. This platform is positioned at the same center of gravity as two horizontal bars. Two sets of storage boxes can be used to store goods. Under the weight of the goods, multiple storage boxes can rotate around the horizontal bars, maintaining balance between the two turntables. By setting two multi-section lifting rods and activating a servo motor, a scissor-type structure can be used to lift the platform, ensuring the platform and the two turntables are aligned on the same axis. This prevents the center of gravity from deviating from the axis when the goods are too heavy, thus making the lifting platform more stable. While this patent offers some advantages, the amount of construction materials taken from the storage boxes on both sides cannot be guaranteed to be consistent during use. Therefore, the weight on both sides of the platform cannot be kept consistent, failing to effectively solve the tilting problem. Furthermore, after the construction materials are used up, the platform needs to be lowered and then placed back into the storage boxes, which is laborious.

[0004] Therefore, in order to ensure the stability of the platform and eliminate the need to lower it again to add more raw materials after the materials are used up, an intelligent lifting platform is proposed to solve the technical problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent lifting platform, comprising a lifting platform base, a scissor lift rod, a platform, and a first drive structure. The drive structure is installed on the upper surface of the lifting platform base, the scissor lift rod is connected to the drive structure, the platform is located at the upper end of the scissor lift rod, and a lifting structure is installed on the lower surface of the platform. The lifting structure includes a frame structure and a second drive structure. The second drive structure is installed on the lower surface of the platform, and its platform surface has an opening. Square plates are installed on both sides of the opening on the lower surface of the platform. The frame structure is movably installed on the surface of the square plates through a connecting structure. The frame structure includes a lifting frame and elongated teeth. The connecting structure includes a first slide rail and a first slider. The first slider is fixedly installed on the surface of the square plates, and the first slide rail is installed on the outer surface of the lifting frame. Elongated teeth are also installed on the front end face of the lifting frame, and the elongated teeth are connected to the drive structure. A bearing block is also installed on the inner side of the lifting frame, and a storage box is placed on the bearing block. A sealing plate is installed on the upper surface of the lifting frame.

[0007] Furthermore, through the above technical solution, the second drive structure includes a first mounting plate, a second servo motor, a rotating shaft, and a gear; the first mounting plate is mounted on the lower end face of the platform, the second servo motor is mounted on the lower end face of the first mounting plate, the output end of the second servo motor is connected to the rotating shaft, the rotating shaft surface is mounted with a gear, and the gear and the long tooth form a gear connection.

[0008] Furthermore, the first drive structure includes a first servo motor and a lead screw; the first servo motor is installed on the left side of the moving base of the elevator, and the output end is connected to a lead screw that extends to the right through the moving base of the elevator via a coupling. A bearing seat is installed on the upper end face of the moving base of the elevator, and the surface of the lead screw is connected to the inner ring of the bearing seat.

[0009] As a preferred technical solution, the upper end face of the moving base of the elevator is symmetrically equipped with a support frame, and the lower end face of the platform is in contact with the upper end face of the support frame in the initial state of the elevator.

[0010] Furthermore, the upper end face of the movable base of the elevator is symmetrically equipped with an installation frame, a second slide rail is installed on the inner side of the installation frame, a second slider is movably connected to the surface of the second slide rail, and planar openings are opened at both ends of the movable shaft. A second mounting plate is installed on the planar opening, and the second mounting plate is connected to the second slider. Its lead screw passes through the movable shaft to achieve threaded engagement, and the threads between the two sets of movable shafts have opposite directions.

[0011] As a preferred technical solution, the lower end face of the platform is also equipped with an installation frame, and the inner side of the installation frame is also equipped with a second slide rail and a second slider. The difference is that the moving shaft located at the upper end connection of the scissor lift is set separately, and the two sets of moving shafts are not connected.

[0012] Furthermore, a ladder is installed on the right side of the moving base of the elevator, and the height of the ladder is the same as the height of the platform in the initial state, wherein in the initial state of the platform, the bottom of the lifting frame is in contact with the upper surface of the moving base of the elevator.

The lifting frame is located at the center of the platform, ensuring the stability of the platform. Furthermore, when the raw materials are used up, there is no need to lower the platform; only the lifting frame needs to be lowered for replenishment. This saves a lot of time and is quite convenient. Attached Figure Description

[0025] 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.

[0026] Example

[0027] Please see Figure 1-8 This utility model provides the following technical solution: an intelligent lifting platform, including a lifting platform mobile base 1, a scissor lift rod 5, a platform 6, and a first drive structure. The drive structure is installed on the upper surface of the lifting platform mobile base 1. The scissor lift rod 5 is connected to the drive structure. The platform 6 is located on the upper end of the scissor lift rod 5. A lifting structure for driving the frame structure to lift is installed on the lower surface of the platform 6. The lifting structure includes a frame structure and a second drive structure. The second drive structure is installed on the lower surface of the platform 6. The surface of the platform 6 has an opening. Square supports for providing installation positions for the first slider 18 are installed on both sides of the opening on the lower surface of the platform 6. The square plate 19 has a frame structure that is movably mounted on its surface via a connecting structure. The frame structure includes a lifting frame 10 and a long tooth 16. The connecting structure includes a first slide rail 17 and a first slider 18. The first slider 18 is fixedly mounted on the surface of the square plate 19. The first slide rail 17 is mounted on the outer surface of the lifting frame 10. The front end face of the lifting frame 10 is also equipped with a long tooth 16, which is connected to the drive structure. A bearing block is also installed on the inner side of the lifting frame 10, and a storage box 23 is placed on the bearing block. A sealing plate 15 is installed on the upper end face of the lifting frame 10 to prevent construction workers from stepping into empty spaces.

[0028] In this implementation plan, the specific working principle is as follows: In the initial state, the platform 6 is in contact with the end face of the support frame 4, and the bottom of the lifting frame 10 is in contact with the surface of the moving base of the elevator. At this time, the construction personnel place the construction materials into the storage box 23, and then start the first drive structure to drive the scissor lift rod 5 to move, thereby moving the platform 6 upward. When it moves to an appropriate height, the first drive structure stops running, and the second drive structure starts, driving the lifting frame 10 to move upward through the opening on the surface of the platform 6, so that the storage box 23 is located above the platform 6, which makes it convenient for the construction personnel to take out the materials for construction. When the materials are used up, the second drive structure can be used to drive the lifting frame 10 downward. This is more convenient, without the need to lower the platform 6 to take out the materials, which can save a lot of time. Secondly, the position of the lifting frame 10 is in the center of the platform 6, which is conducive to the stability of the platform 6.

[0029] Based on the above, please refer to the details of activating the second drive structure. Figure 2 , Figure 4 , Figure 6-7 As can be seen, the second drive structure includes a first mounting plate 11, a second servo motor 12, a rotating shaft 13, and a gear 14. The first mounting plate 11 is mounted on the lower end face of the platform 6. The second servo motor 12 is mounted on the lower end face of the first mounting plate 11. The output end of the second servo motor 12 is connected to the rotating shaft 13. The rotating shaft 13 is mounted on the surface of the rotating shaft 13. The gear 14 and the long tooth 16 form a gear connection. The second servo motor 12 drives the rotating shaft 13 to rotate. At this time, the gear 14 and the long tooth 16 are gear meshed. Therefore, after the servo motor 12 is started, it can drive the lifting frame 10 to move.

[0030] For details on how the first drive structure moves the scissor lift lever 5, please refer to [link / reference needed]. Figure 2 , Figure 3 , Figure 5 , Figure 8 As can be seen, the first drive structure includes a first servo motor 3 and a lead screw 8. The first servo motor 3 is installed on the left side of the moving base 1 of the lifting platform, and the output end is connected to the lead screw 8 through the moving base 1 and extends to the right. A bearing seat is installed on the upper end face of the moving base 1. The surface of the lead screw 8 is connected to the inner ring of the bearing seat. The first servo motor 3 drives the lead screw 8 to rotate, which in turn drives the moving shaft 9 to move. It should be noted that the threads on both sides of the lead screw are opposite from the center and correspond to the internal threads of the corresponding moving shaft 9. Therefore, it can drive the two sets of moving shafts 9 to move in opposite directions, thereby realizing the lifting operation of the scissor lift 5.

[0031] For details on providing support for Platform 6, please refer to [link / reference]. Figure 1-3As can be seen, the upper end face of the moving base 1 of the elevator is symmetrically mounted with the support frame 4, and the lower end face of the platform 6 is in contact with the upper end face of the support frame 4 in the initial state of the elevator.

[0032] For details on facilitating the movement of axis 9, please refer to [link / reference needed]. Figure 3 , Figure 5 , Figure 8 As can be seen, the upper end face of the moving base 1 of the elevator is symmetrically equipped with an installation frame 7, and a second slide rail 21 is installed on the inner side of the installation frame 7. A second slider 22 is movably connected to the surface of the second slide rail 21. The left and right ends of the moving shaft 9 are provided with planar openings, and a second mounting plate 20 is installed on the planar surface. The second mounting plate 20 is connected to the second slider 22, and its lead screw 8 passes through the moving shaft 9 to achieve threaded engagement. The threads of the two sets of moving shafts 9 have opposite directions of rotation.

[0033] To prevent the moving shaft 9 located at the upper end of the scissor lift arm 5 from colliding with the lifting frame 10 during descent, please refer to [reference needed]. Figure 2 , Figure 4 , Figure 5 As can be seen, the lower end face of the platform 6 is also equipped with an installation frame 7, and the inner side of the installation frame 7 is also equipped with a second slide rail 21 and a second slider 22. The difference is that the moving shaft 9 located at the upper end connection of the scissor lift 5 is set separately, and the two sets of moving shafts 9 are not connected.

[0034] For details regarding access to platform 6 by construction workers, please refer to [link / reference needed]. Figure 1 As can be seen, a ladder 2 is installed on the right side of the elevator mobile base 1. The height of the ladder 2 is the same as the height of the platform 6 in the initial state. In the initial state of the platform 6, the bottom of the lifting frame 10 is in contact with the upper surface of the elevator mobile base 1.

[0035] 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.
