DETAILED DESCRIPTION
[0020] Example 1
[0021] like Figure 1 、 Figure 2 As shown, this embodiment includes a drive motor 1, a first sprocket 2, a second sprocket 3, a third sprocket 4, a connecting plate 5, a chain 6, a tension spring 7 and a column 8.
[0022] This embodiment is provided with two vertically positioned mounting plates 15, with the drive motor 1 secured to one of the mounting plates 15. The output end of the drive motor 1 is connected to the first sprocket 2, which can drive the first sprocket 2 to rotate about its axis. This embodiment is provided with two first sprockets 2, with the other first sprocket 2 being mounted on the other mounting plate 15. Specifically, this can be achieved by a connecting shaft, one end of which is secured to the other mounting plate 15, and the other first sprocket 2 being sleeved on the other end of the connecting shaft and capable of self-rotation. The two first sprockets 2 are connected by a connecting rod 13, meaning that the drive motor 1 can simultaneously drive both first sprockets 2 to rotate.
[0023] The second sprocket 3 and the third sprocket 4 are respectively arranged at both ends of the connecting plate 5, and the second sprocket 3 and the third sprocket 4 can rotate freely around their respective axis lines. The connection method of the second sprocket 3, the third sprocket 4 and the subsequent fourth sprocket 9 can refer to the connection method of another first sprocket 2 and another mounting plate 15, which will not be repeated here.
[0024] One end of the chain 6 is fixed, specifically, a fixing block 16 is provided, the fixing block 16 is fixed on the mounting plate 15, and one end of the chain 6 is fixed on the fixing block 16. The fixing block 16 and the first sprocket 2 are respectively arranged above both sides of the connecting plate 5.
[0025] Chain 6 sequentially passes under the second and third sprockets 3 and 4, then over the first sprocket 2, forming a structure in which the first sprocket 2 and the fixing block 16 suspend the connecting plate 5 via the chain 6. After passing over the first sprocket 2, chain 6 passes under the fourth sprocket 9 before being secured to one end of a tension spring 7. The fourth sprocket 9 is mounted on a mounting plate 15. The other end of the tension spring 7 is fixed. The fixing method for the tension spring 7 can be found in the fixing structure of the fixing block 16 and the tension spring 7.
[0026] The fourth sprocket 9 provided in this embodiment mainly serves to tension the chain 6 . In other embodiments, the fourth sprocket 9 may not be provided, and the chain 6 passing through the first sprocket 2 may be directly connected to the tension spring 7 .
[0027] In this embodiment, column 8 is mounted upright on connecting plate 5. To ensure vertical up and down movement of column 8, column 8 is configured as an optical axis and a linear bearing 11 is provided. Linear bearing 11 is secured to mounting plate 15 and sleeved onto column 8. A support plate 12 is provided at the end of column 8 to support materials. Of course, in other embodiments, support plate 12 may be omitted, and the end of column 8 may serve as the supporting end. Multiple columns 8 may be arranged side by side on a single mounting plate 15.
[0028] This embodiment further provides a support rod 14, the ends of which are respectively connected to the columns 8 on the two mounting plates 15. The support rod 14 can be directly connected to the columns 8 or to the support plates 12. A plurality of linearly arranged support plates 12 are further provided on the support rod 14, each of which can be used to place the material to be lifted, thereby achieving simultaneous lifting of multiple materials.
[0029] Preferably, this embodiment also includes a slide rail 10 and a slider. The slide rail 10 is vertically fixed to the mounting plate 15, and the slider is mounted on the connecting plate 5, allowing the slider to slide up and down on the slide rail 10. In this embodiment, the connecting plates 5 on both mounting plates 15 are equipped with sliders and slide rails 10, and each mounting plate 15 is equipped with two parallel slide rails 10, with the sliders on the two slide rails 10 being respectively mounted at the ends of the connecting plate 5. In other embodiments, each mounting plate 15 may be equipped with only one slide rail 10.
[0030] Example 2
[0031] The difference between this embodiment and embodiment 1 is that this embodiment only has one set of first sprocket 2, second sprocket 3, third sprocket 4, connecting plate 5, chain 6, tension spring 7 and column 8, and the first sprocket 2 is directly driven by the drive motor 1. Therefore, this embodiment is only used to lift a single material.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
