[0002] The lifting platform is a vertically moving lifting machinery, which is mainly used for transporting goods between height differences in production lines, loading and unloading materials, feeding materials from high feeders, and lifting components during assembly of large equipment.

[0003] In the related art, a Chinese patent with authorization announcement number CN217732573U provides a screw lift for cargo transportation. The screw comprises a fixed base, a screw and several guide posts extending through the fixed base. The screw is threadedly connected to the fixed base, the guide posts are slidably connected to the fixed base, and a lifting platform is mounted on the top of the guide posts and the screw. The lifting platform is arranged parallel to the fixed base. The screw rotates and moves along the fixed base, thereby driving the lifting platform to rise and fall.

[0004] In the process of implementing this application, the inventor discovered that there are at least the following problems in this technology: since the bottom of the screw extends to the bottom of the fixed base, sufficient space must be reserved below the fixed base to provide the necessary clearance space for the screw so that the screw can smoothly drive the lifting platform to perform lifting movements. Therefore, the space requirements for the use of the elevator are relatively high. This high space requirement makes the elevator susceptible to space restrictions in actual applications, making it inconvenient to be flexibly used in a variety of different scenarios.

[0041] Reference Figures 1 to 7, a cover shell 8 is installed on the base 1, and an accommodating chamber 81 is formed between the cover shell 8 and the base 1. A driving motor 7 is fixedly installed in the accommodating chamber 81, and a driving gear 71 is installed on the output shaft of the driving motor 7. A left support shaft 31 is provided through the left lower arm 3, and the left support shaft 31 is welded to the left lower arm 3. A left support seat 32 is rotatably provided at one end of the left support shaft 31, and the left support seat 32 is welded to the base 1. The other end of the left support shaft 31 passes through the cover shell 8, and the left support shaft 31 is rotatably connected to the cover shell 8. A left gear 33 is welded at one end of the left support shaft 31 located in the accommodating chamber 81, and the left gear 33 is meshed with the driving gear 71. A right support shaft 41 is provided through the right lower arm 4, and the right support shaft 41 is welded to the right lower arm 4. A right support seat 42 is rotatably provided at one end of the right support shaft 41, and the right support seat 42 is welded to the base 1. The other end of the right support shaft 41 extends through the housing 8 and is rotatably connected to the housing 8. The right support shaft 41 is located within the accommodating cavity 81 and has a right gear 43 welded to one end. The right gear 43 meshes with the drive gear 71. A front support shaft 51 extends through the front lower arm 5 and is welded to the front lower arm 5.

The other end of the front support shaft 51 extends through the housing 8 and is rotatably connected to the housing 8. The front gear 53 is welded to one end of the front support shaft 51 and is meshed with the drive gear 71. A rear support shaft 61 extends through the rear lower arm 6 and is welded to the rear lower arm 6. A rear support seat 62 is pivotally mounted on one end of the rear support shaft 61 and is welded to the base 1. The other end of the rear support shaft 61 passes through the housing 8 and is rotatably connected to the housing 8. A rear gear 63 is welded to one end of the rear support shaft 61 within the accommodating cavity 81. The rear gear 63 meshes with the drive gear 71. When the drive motor 7 is activated, the drive gear 71 rotates. This rotation of the drive gear 71 synchronously rotates the left gear 33, the right gear 43, the front gear 53, and the rear gear 63. The rotation of the left gear 33 rotates the left lower arm 3, the rotation of the right gear 43 rotates the right lower arm 4, the rotation of the front gear 53 rotates the front lower arm 5, and the rotation of the rear gear 63 rotates the rear lower arm 6.

[0042] Reference Figures 1 to 7 The top of the cover shell 8 is covered with a rubber layer 82. When the top seat 2 descends onto the cover shell 8, the rubber layer 82 buffers the force of the top seat 2 on the cover shell 8, thereby reducing the vibration of the drive motor 7 in the cover shell 8.

[0043] refer to Figures 1 to 7 , a limit seat 91 is installed on the side wall of the cover shell 8, and a limit switch 9 is installed on the limit seat 91.

[0044] The operating principle of an electric transport lift according to an embodiment of the present application is as follows: When the lifting platform 11 is raised or lowered, the drive motor 7 is activated to drive the drive gear 71 to rotate. The rotation of the drive gear 71 drives the left gear 33, the right gear 43, the front gear 53, and the rear gear 63 to rotate synchronously. The rotation of the left gear 33 drives the left lower arm 3 to rotate, causing the left upper arm 21 and the left lower arm 3 to rotate relative to each other. The rotation of the right gear 43 drives the right lower arm 4 to rotate, causing the right upper arm 22 and the right lower arm 4 to rotate relative to each other. The rotation of the front gear 53 drives the front lower arm 5 to rotate, causing the front upper arm 23 and the front lower arm 5 to rotate relative to each other. The rotation of the rear gear 63 drives the rear lower arm 6 to rotate, and the rear upper arm 24 and the rear lower arm 6 to rotate relative to each other. The left upper arm 21, the right upper arm 22, the front upper arm 23, and the rear upper arm 24 jointly drive the top base 2 to move in the height direction, and the top base 2 drives the lifting platform 11 to rise or fall. The left upper arm 21, the left lower arm 3, the right upper arm 22, the right lower arm 4, the front upper arm 23, the front lower arm 5, the rear upper arm 24 and the rear lower arm 6 are located between the base 1 and the lifting platform 11. Therefore, there is no need to reserve sufficient space under the base 1, which reduces the space requirements of the elevator, expands the scope of application of the elevator, and facilitates flexible application of the elevator.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
