Description

Technical Field

[0001] This utility model relates to material handling technology, specifically an electric turntable. Background Technology

[0002] Pallets are a medium that transforms static goods into dynamic goods; they are a cargo platform, and moreover, a mobile platform, or a movable ground. Even goods that lose their flexibility when placed on the ground immediately gain mobility and become flexible, flowing goods once loaded onto a pallet, because goods loaded on a pallet are always in a ready-to-move state.

[0003] To facilitate loading goods onto pallets or moving pallets onto transport vehicles, pallets often need to be rotated and repositioned. Pallet rotation is usually done manually, which is physically demanding for workers. In particular, when pallets are heavy or already loaded with goods, forklifts or other machinery are required.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] Example 1:

[0023] like Figure 1 As shown, an electric turntable includes a base 1, a rotating unit and a rotating platform 2 above the base 1, the rotating unit drives the rotating platform 2 to rotate, side frames 3 are provided on both sides of the top of the rotating platform 2, and rollers 4 are evenly distributed between the two side frames 3. The rollers 4 are driven to rotate by a moving unit located on the side frames 3, and a clamping unit is provided in the middle of the rotating platform 2 for limiting the tray.

[0024] like Figure 2 As shown, the clamping unit includes a front deflector assembly and two side clamping assemblies. The front deflector assembly is located at one end of the rotating platform 2, and the two side clamping assemblies are respectively disposed on both sides of the rotating platform 2. The front deflector assembly includes two front deflector cylinders 8 and two front deflector blocks 7. The front deflector cylinders 8 are fixed to the top of the rotating platform 2 and drive the front deflector blocks 7 to rise and fall. The side clamping assembly includes two side clamping cylinders 10 and two side clamping blocks 9. The side frame 3 cylinder is fixed to the top of the rotating platform 2 and drives the side clamping blocks 9 to move closer to or away from the side frame 3.

[0025] The moving unit causes the roller 4 to rotate, allowing the pallet to be loaded. The front stop 7 blocks the pallet, indicating that the pallet is in place. Then, the side clamping cylinder 10 drives the side clamping block 9 to move, clamping both sides of the pallet to achieve clamping and limiting of the pallet, so as to facilitate the rotation of the pallet and loading.

[0026] like Figure 3 As shown, the rotating unit includes a rotary motor 11, a gear 12 and a gear ring 13. The rotary motor 11 is fixed to the base 1. The rotary motor 11 drives the gear 12 to rotate. The gear 12 meshes with the gear ring 13. The gear ring 13 is fixed to the bottom of the rotating platform 2.

[0027] The electric turntable in this embodiment uses a rotating unit that can quickly rotate the rotating platform 2, causing the tray on the rotating platform 2 to rotate, thereby increasing the tray position adjustment speed. In conjunction with the clamping unit, it can quickly clamp the tray, confine the tray to the rotating platform 2, prevent the tray from shifting, and avoid the tray from detaching from the rotating platform 2 during rotation.

[0028] The moving unit includes a moving motor 5, a chain and several sprockets. The sprockets are coaxially arranged on the output shaft of the moving motor 5 or the end of the roller 4. The chain passes around the sprockets in sequence and is connected end to end.

[0029] The side frame 3 is equipped with guide bars 6; the guide bars 6 can guide the movement of the pallet and prevent the pallet from rotating automatically.

[0030] The gear ring 13 is fitted onto the outer ring of the bearing, and the inner ring of the bearing is fixed to the base 1.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
