Description

[0002] The conventional elevator is generally in vertical lifting mode, which is composed of a frame, a driving mechanism, a lifting frame, a counterweight and a control system. The lifting frame is used for lifting or lowering objects. Depending on the different objects, a certain horizontal conveyor may be configured on the lifting frame, and the objects are conveyed into the horizontal conveyor. If the object to be lifted is a self-propelled trolley, a track can be configured on the lifting frame, and the self-propelled trolley can enter the track and rise or fall with the lifting frame. After reaching the destination height, the self-propelled trolley can automatically leave the lifting frame.

[0003] Modern automobile factories or other industrial enterprises have higher and higher requirements for high productivity and low energy consumption. The disadvantage of the conventional elevator is that when the object or self-propelled trolley to be lifted reaches the destination height, the lifting frame must be empty to return to continue lifting the next object or self-propelled trolley. Therefore, the time for lifting the object is prolonged, the efficiency is reduced, and energy is wasted.

The end points of the rotating frame 9 are rotatably connected with the bearing mechanisms. The rotating frame 9 is fixedly connected with a rotating shaft 11. The rotating shaft 11 is rotatably connected with the small bearing seat 31 and the large bearing seat 5. The rotating shaft 11 is fixedly connected with the large gear 4.

[0038] The elevator of the present application adopts a rotary lifting mode and is composed of a frame, a motor, a rotating frame 9, a bearing mechanism and a bearing rail system. The rotating frame 9 can rotate 360° around a horizontal axis. The rotating frame 9 is provided with four groups of bearing mechanisms symmetrically arranged around the rotating center. During the rotation of the rotating frame 9, the bearing rail always remains horizontal. The self-propelled trolley 18 can enter the bearing rail at a high or low position, or leave the bearing rail after reaching a low or high position, and always remains horizontal during the rotation of the rotating frame 9 and will not fall due to rotation.

[0039] During the rotation of the rotating frame 9, the tracks on each carrying mechanism remain horizontal, ensuring that the trolleys 18 on the tracks do not fall. Each carrying mechanism can be kept horizontal by gravity, electricity or other mechanisms. The rotating mechanism rotates by a fixed angle each time, and a carrying mechanism is raised to a position, the transported material or trolley can leave, and the elevator does not need to return empty. The fixed angle is determined by the number of carrying mechanisms, for example, 180° for two carrying mechanisms and 90° for four carrying mechanisms.

[0040] Specifically, a trolley 18 enters the carrying track at a high position and rotates to an upper carrying mechanism. As the rotating frame 9 rotates, the trolley 18 moves from the high position to the low position, and then leaves the carrying track. At the same time, another trolley 18 enters another carrying track at a high position. The rotating frame 9 continues to rotate, and the second trolley 18 reaches the low position and leaves. The rotating frame 9 stops every 90°, and the trolley 18 that reaches the low position leaves and waits for the next trolley to enter at the high position. This cycle continues, and the carrying track does not need to return empty, saving time and reducing energy consumption.
