[0004] However, although the existing eccentric turntables can transfer goods by changing the angle of the goods, due to the limitation of the construction site of the transportation system, when docking goods with other transportation devices, it is necessary to raise or lower the receiving position of the eccentric turntable, which is not conducive to the construction of the transportation system and the transfer of goods.

[0005] Therefore, it is necessary to provide a lifting platform for an eccentric turntable to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technical part is only used to understand the background technology of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Utility Model Content

Detailed Embodiment

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figures 1-4, the embodiments provided by the present utility model:

[0031] A lifting platform for an eccentric turntable, comprising a lower support frame 1 installed on the eccentric turntable. Hydraulic cylinders 2 are respectively installed at the four corners of the top surface of the lower support frame 1. The end parts of the telescopic shafts of the hydraulic cylinders 2 are respectively installed corresponding to the four corners of the bottom surface of the upper support frame 3. By synchronously controlling the telescopic lengths of the telescopic shafts of the four hydraulic cylinders 2, the distance between the upper support frame 3 and the lower support frame 1 is adjusted, so that the upper support frame 3 can move up and down relative to the lower support frame 1, and thus can be adjusted to the corresponding height according to the height of other transportation devices. Among them, a plurality of rollers can be installed on the upper support frame 3 and, in cooperation with a driving device, the articles on the upper support frame 3 can be transported and processed.

[0032] First limiting mechanisms 4 for maintaining vertical lifting are respectively installed on both sides between the upper support frame 3 and the lower support frame 1. The first limiting mechanism 4 includes a mounting plate 41 and a guide rod 42. The mounting plate 41 is respectively fixedly installed on both sides of the bottom surface of the upper support frame 3 by screws. The guide rods 42 are respectively welded to the center of the bottom surface of the mounting plate 41. Through holes 43 are respectively formed in the lower support frame 1 at the positions of the guide rods 42. The side wall of the guide rod 42 is slidably connected with the inside of the through hole 43. A limiting plate 44 is fixedly installed at the bottom end of the guide rod 42.

[0033] During the lifting process of the lower support frame 1 and the upper support frame 3, the guide rod 42 can slide in the through hole 43 formed in the lower support frame 1, and the maximum moving amplitude of the guide rod 42 is limited by the limiting plate 44 to prevent it from running out of the through hole 43. Through the first limiting mechanism 4, it is ensured that the lifting of the lower support frame 1 and the upper support frame 3 is in vertical up and down movement, so as to ensure the moving stability of the lifting platform.

[0034] Second limiting mechanisms 5 are respectively installed at the middle positions between the upper support frame 3 and the lower support frame 1. The second limiting mechanism 5 includes an upper mounting seat 51, a lower mounting seat 52, a chute 53, a sliding seat 54, a first rotating plate 55, a second rotating plate 56 and a mounting groove 57. The upper mounting seat 51 is fixedly installed at the middle section of the bottom surface of the upper support frame 3 by screws. The lower mounting seat 52 is fixedly installed at the middle section of the bottom surface of the lower support frame 1 by screws. Mounting grooves 57 are formed inside the upper mounting seat 51 and the lower mounting seat 52. Chutes 53 are formed through the side walls of the upper mounting seat 51 and the lower mounting seat 52. The sliding seat 54 is slidably connected in the chute 53. The center of the first rotating plate 55 is rotatably connected with the center of the second rotating plate 56. The two ends of the first rotating plate 55 and the second rotating plate 56 are respectively rotatably connected with the side walls of the sliding seat 54 in the chutes 53 of the upper mounting seat 51 and the lower mounting seat 52.

[0035] Specifically, the sliding seat 54 includes a slider and a first fixed shaft 6. Both ends of the first fixed shaft 6 are fixedly installed with the slider. First shaft holes 7 are respectively formed at both end portions of the first rotating plate 55 and the second rotating plate 56. The first rotating plate 55 and the second rotating plate 56 are rotatably connected to the side wall of the first fixed shaft 6 through the first shaft holes 7. A rotating groove 8 is formed on the side wall of the first rotating plate 55, and the second rotating plate 56 is slidably connected in the rotating groove 8. A second shaft hole is formed at the cross center position of the first rotating plate 55 and the second rotating plate 56, and a second fixed shaft 9 is inserted into the second shaft hole. Limit plates 10 are respectively installed at both ends of the second fixed shaft 9.

[0036] The working principle of the second limiting mechanism 5 is as follows: When the telescopic lengths of the telescopic shafts of the four hydraulic cylinders 2 change, the distance between the upper support frame 3 and the lower support frame 1 increases. As a result, the first rotating plate 55 and the second rotating plate 56 rotate relative to each other through the second fixed shaft 9 in the second shaft hole, and the second rotating plate 56 slides in the rotating groove 8 formed on the side wall of the first rotating plate 55. At the same time, since the lengths of the first rotating plate 55 and the second rotating plate 56 remain unchanged, the two end portions of the first rotating plate 55 and the second rotating plate 56 not only rotate on the first fixed shaft 6 of the sliding seat 54 respectively, but also drive the sliding seat 54 to slide in the sliding groove 53 and the installation groove 57 respectively, so as to ensure that the first rotating plate 55 and the second rotating plate 56 change according to the distance between the upper support frame 3 and the lower support frame 1.

[0037] Through the cooperation of the upper mounting seat 51 and the lower mounting seat 52 of the second limiting mechanism 5 and the sliding seat 54 that slides, the first rotating plate 55 and the second rotating plate 56 can be adjusted according to the distance between the upper support frame 3 and the lower support frame 1. Thus, it is ensured that during the lifting process of the upper support frame 3 and the lower support frame 1, the upper support frame 3 will not tilt or shift. At the same time, in cooperation with the first limiting mechanism 4, it is ensured that the goods will not fall during the roller transportation on the upper support frame 3.

[0038] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
