[0015] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.
[0016] [Example 1]
[0017] A lift, such as Figure 1 , including a lift body, the lift body including a frame 1 and a top frame 11 arranged at the top of the frame 1, a fixed pulley assembly is arranged on the top frame 11, a cargo platform 2 is arranged in the frame 1, and a lifting device 3 for adjusting the cargo platform is arranged on the frame 1; the lifting device includes a mounting seat 31, a drum 34 and a driving motor 32, the drum 34 is installed on the mounting seat 31, the driving motor 32 is connected to the drum 34, the cargo platform 2 is connected to the drum 34 through a wire rope 12, and the driving motor 32 drives the drum 34 to rotate, thereby driving the cargo platform 2 to move up and down.
[0018] like Figure 2-Figure 3 An adjusting device is provided on the frame 1, and the adjusting device includes an adjusting drive assembly 35 and a swing arm 33. The swing arm 33 is connected to the drum 34. The adjusting drive assembly 35 is used to drive the swing arm 33 to move. The movement trajectory of the swing arm 33 is a rotation movement around the rotation center of the drum 34. When the adjusting drive assembly 35 drives the swing arm 33 to move, the drum 34 is rotated, thereby the winding wire rope 12 drives the cargo platform 2 to move, thereby realizing the leveling of the cargo platform 2.
[0019] Specifically, the adjustment drive assembly 35 can be a drive element such as a cylinder, a hydraulic cylinder or a motor, and can be connected through a connecting rod structure and a gear structure to drive the swing arm 33 to swing. The swing arm 33 can be connected to the reel 34 or the drive motor 32. In this embodiment, Figure 3 , the adjusting drive component 24 is an adjusting motor.
[0020] A driving gear 36 is installed on the adjusting motor, and a meshing portion 37 is provided on the swing arm 33. The driving gear 36 is connected to the meshing portion 37, and the meshing portion 37 is a plurality of teeth. The end of the swing arm 33 away from the driving gear 36 is connected to the driving motor 32. When the driving gear 36 rotates, the meshing portion 37 drives the swing arm 33 to rotate with the rotating shaft of the drum 34 as the rotation center, thereby driving the driving motor 32 to rotate as a whole. The driving motor needs to have a self-locking function. The driving motor 32 rotates as a whole and then causes the drum 34 to rotate to a certain extent, so as to achieve the height adjustment of the cargo platform 2 and the leveling effect between the floors. Specifically, the meshing portion 37 can be understood as a part of a circular gear, and the center of the circular gear is the rotation center of the drum 34. The swing arm 33 can also be directly connected to the rotating shaft of the drum 34. These two connection methods can be arbitrarily selected according to actual conditions.
[0021] In short, the main function of the driving motor 32 is to control the lifting and lowering, and the main function of the regulating motor is to fine-tune the rotation of the reel 34 to achieve the height adjustment of the cargo platform 2.
[0022] The regulating motor can be controlled by a PLC single chip computer, a microprocessor, a computer, etc., and different regulating amounts of the motor can be set for different floors.
[0023] Preferably, the lifting device 3 and the adjusting device are respectively arranged on two adjacent side surfaces of the frame 1 to reduce the occupied space and facilitate installation.
[0024] Preferably, if Figure 3 There are two groups of mounting seats 31, which are respectively arranged on both sides of the reel 34.
[0025] The utility model provides a lift which can effectively ensure the levelness of a cargo platform and a corresponding floor, and has a simple structure, is easy to use and has high reliability.
[0026] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed and modified in any way.
