[0020] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.
[0021] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the accompanying drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.
[0022] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.
[0023] The following refers to Figures 1-3 to describe in detail the implementation of the lifting mechanism according to an embodiment of the present utility model.
[0024] The lifting mechanism according to an embodiment of the present utility model includes: a first bracket 1, a second bracket 2, and a first chain drive assembly 3.
[0025] Specifically, the first bracket 1 defines an accommodation space, and a mounting plate 15 is provided at the top of the accommodation space; the second bracket 2 is movably connected to the first bracket 1 within the accommodation space; the first chain drive assembly 3 has a rotary drive member 31, a first chain 32, and a first sprocket 33 meshing with the first chain 32. The rotary drive member 31 is disposed on the mounting plate 15, the first sprocket 33 is connected to the output end of the rotary drive member 31, one end of the first chain 32 is connected to the top of the second bracket 2, and the other end of the first chain 32 is connected to the bottom of the second bracket 2. The rotary drive member 31 is adapted to drive the first sprocket 33 to rotate, so that the first chain 32 drives the second bracket 2 to move between a position extending out of and retracting into the accommodation space.
[0026] That is to say, the accommodation space of the first bracket 1 can facilitate the arrangement of the second bracket 2 in the accommodation space and be movably connected to the first bracket 1. The mounting plate 15 of the first bracket 1 is arranged to facilitate the installation of the rotation driving member 31 of the first chain 32 assembly. When the rotation driving member 31 drives the first sprocket 33 to rotate, the first sprocket 33 can drive the first chain 32 connected to the second bracket 2 to move, thereby driving the second bracket 2 to move between the positions of extending out of the accommodation space and retracting into the accommodation space, facilitating the lifting movement of the processing component on the second bracket 2 for processing, improving the load-bearing capacity of the overall lifting mechanism, and facilitating the storage of the second bracket 2 while reducing the occupied space of the overall lifting mechanism.
[0027] Thus, the first chain drive assembly 3 drives the second bracket 2 to extend out of the accommodation space of the first bracket 1 or retract into the accommodation space of the first bracket 1, thereby realizing the lifting movement of the second bracket 2, facilitating the lifting movement of the processing component on the second bracket 2 for processing the processing object, with a simple structure, strong load-bearing capacity, and small floor space.
[0028] For the first bracket 1, the first bracket 1 has a first vertical rod 11, a second vertical rod 12, and a base 13. One end of the first vertical rod 11 and the second vertical rod 12 is connected to the base 13, and the other end of the first vertical rod 11 and the second vertical rod 12 is connected to the mounting plate 15. The base 13, the first vertical rod 11, and the second vertical rod 12 jointly construct the accommodation space. Understandably, by connecting one end of the first vertical rod 11 and the second vertical rod 12 to the base 13 and the other end of the first vertical rod 11 and the second vertical rod 12 to the mounting plate 15, it is convenient to improve the overall stability of the first bracket 1. By jointly constructing the accommodation space by the base 13, the first vertical rod 11, and the second vertical rod 12, it is convenient to switch between the storage state and the extended state of the second bracket 2, reducing the occupied space of the overall lifting mechanism. Among them, the lifting mechanism can install the overall lifting mechanism on the AGV trolley through the base 13 and move the lifting mechanism to different processing positions.
[0029] For the second bracket 2, the second bracket 2 has a third vertical rod 21, a fourth vertical rod 22, a first cross rod 23 and a second cross rod 24. The first cross rod 23 connects one ends of the third vertical rod 21 and the fourth vertical rod 22, and the second cross rod 24 connects the other ends of the third vertical rod 21 and the fourth vertical rod 22. The third vertical rod 21 and the fourth vertical rod 22 are movably connected to the first vertical rod 11 and the second vertical rod 12 in a one-to-one correspondence. It can be understood that through the arrangement of the third vertical rod 21, the fourth vertical rod 22, the first cross rod 23 and the second cross rod 24, the stability of the overall connection of the second bracket 2 can be facilitated, thereby improving the load-bearing capacity of the second bracket 2. By movably connecting the third vertical rod 21 and the fourth vertical rod 22 to the first vertical rod 11 and the second vertical rod 12 in a one-to-one correspondence, the second bracket 2 can be easily moved relative to the first bracket 1, so as to realize the lifting movement under the drive of the first chain drive assembly 3. Among them, the third vertical rod 21 and the fourth vertical rod 22 and the first vertical rod 11 and the second vertical rod 12 can be connected by the cooperation of a slide rail and a slider. The first vertical rod 11, the second vertical rod 12, the third vertical rod 21 and the fourth vertical rod 22 can be made of square steel or aluminum profiles, which is beneficial to cost control.
[0030] For the installation of the first chain 32, one end of the first chain 32 is connected to the first cross rod 23, and the other end of the first chain 32 is connected to the second cross rod 24. It can be understood that by connecting one end of the first chain 32 to the first cross rod 23 and the other end of the first chain 32 to the second cross rod 24, it is convenient for the first chain 32 to connect between the top and the bottom of the first bracket 1, so as to facilitate driving the first chain 32 to lift by the first sprocket 33, and further drive the overall lifting of the first bracket 1, which can improve the load-bearing capacity of the second bracket 2. Among them, the number of the first chains 32 can be two, and three first sprockets 33 can be arranged on the rotary drive member 31, which is convenient for the winding and tensioning of the first chain 32 and improves the reliability of the meshing between the first sprocket 33 and the first chain 32.
[0031] For the lifting of the processing component, a second chain drive assembly 4 is further included. The second chain drive assembly 4 has a second chain 41 and second sprockets 42. Second sprockets 42 are provided on both the first cross bar 23 and the second cross bar 24. The second chain 41 meshes with the second sprockets 42 to enable the second chain 41 to rotate around the longitudinal direction of the second bracket 2. It can be understood that through the setting of the second chain drive assembly 4, it is convenient for the processing component to be connected to the second chain 41, and the processing component is driven to lift along the rotation of the second chain 41. That is to say, when the second bracket 2 is in the retracted state, the second chain drive assembly 4 can drive the processing component to move between the first cross bar 23 and the second cross bar 24 of the second bracket 2 for processing in this area. When the first chain drive assembly 3 drives the second bracket 2 to the extended state, the second chain drive assembly 4 drives the processing component to process this area, so as to facilitate the all-round coverage processing of the processing component from low to high. Among them, the number of the second chains 41 can be two, each second chain 41 cooperates with four second sprockets 42, and the rotation of the second chain 41 can be realized by a motor cooperating with a sprocket structure.
[0032] For the reinforcement of the first bracket 1, the first bracket 1 further includes a connecting plate 14, and the connecting plate 14 is adapted to connect the first vertical rod 11 and the second vertical rod 12. It can be understood that by connecting the first vertical rod 11 and the second vertical rod 12 through the connecting plate 14, it is convenient to improve the stability and connection strength of the first bracket 1. Among them, the number of the connecting plates 14 can be multiple, and the multiple connecting plates 14 form an inclined Z-shaped connection with the first vertical rod 11 and the second vertical rod 12 to further improve the connection strength of the first bracket 1.
