The lifting belt is arranged along the length of the lifting device, with one end connected to a drive assembly and the other end connected to a driven pulley assembly. The drive assembly includes a drive motor, a lifting pulley, and a lifting pulley mounting shaft. The drive motor is mounted on the outside of the drive frame and is directly connected to the lifting pulley mounting shaft. The lifting pulley mounting shaft is supported and fixed on a motor mounting base by two bearing seats. The lifting pulley is connected to the lifting pulley mounting shaft through two tensioning sleeves, and the lifting belt is wound around the lifting pulley. This novel large-scale lifting device for automobiles not only simplifies the structure and reduces the frame size, but also exhibits higher stability in the width direction than in the length direction when used on a production line, facilitating production.

Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a new type of large lifting device for automobiles. Background Technology

[0002] During the production of automotive parts, assembly line operations are required across multiple workstations depending on the manufacturing and assembly processes. Large automotive parts, due to their size and weight, are often difficult to transport. Currently, large automotive parts are generally loaded automatically using large lifting devices or manually. Loading with large lifting devices can meet production needs, but it is very expensive, requiring a large initial investment. Manual loading typically involves two operators lifting and carrying the engine, which is not only wasteful of manpower but also physically demanding for the operators and poses safety hazards.

[0003] In existing large lifting devices, the motor is mounted inside the drive frame. The motor is connected to the lifting pulley mounting shaft on one side via two tensioning sleeves, one universal coupling, and the lifting pulley mounting shaft is supported by two bearing seats. The lifting pulley is connected to one tensioning sleeve. This requires 12 tensioning sleeves, 4 universal couplings, and 8 bearing seats to drive one lifting device, and the height of each of the four lifting pulleys needs to be adjusted individually. Furthermore, the lifting belt of existing large lifting devices is arranged along the width direction, resulting in poor stability in that direction. Therefore, the existing technology requires improvement and development. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new type of large lifting device for automobiles, which not only simplifies the structure and reduces the size of the frame, but also has higher stability in the width direction than in the length direction when used on the production line, making it convenient for production.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a new type of large automobile lifting device, including a drive frame and a lifting belt; the lifting belt is arranged along the length direction of the lifting device, one end of the lifting belt is connected to a drive assembly, and the other end of the lifting belt is connected to a driven pulley assembly; the drive assembly includes a drive motor, a lifting pulley, and a lifting pulley mounting shaft; the drive motor is mounted on the outside of the drive frame, the drive motor and the lifting pulley mounting shaft are directly connected, the lifting pulley mounting shaft is supported and fixed on the motor mounting seat by two bearing seats, the lifting pulley is connected to the lifting pulley mounting shaft through two tensioning sleeves, and the lifting belt is wound around the lifting pulley.

[0006] Furthermore, two lifting pulleys are distributed on each side of the lifting pulley mounting shaft.

[0007] Furthermore, the lifting belt and the lifting belt tensioning assembly are connected.

[0008] Furthermore, the drive frame is fixedly connected to the base via an X-shaped support frame.

[0009] Compared with the prior art, the present invention has the following advantages: The new large-scale lifting device for automobiles provided by the present invention installs the drive motor on the outside of the drive frame, reducing the size of the frame. The two lifting pulleys on one side are made into a whole, and the height of the four lifting pulleys can be adjusted at one time, simplifying the structure. The lifting belt is arranged along the length of the lifting device, reducing the swaying of the lifting device in the width direction. When used on the process line, the stability in the width direction is higher than that in the length direction, which is convenient for production. Attached Figure Description

[0016] Please see Figure 1 and Figure 2 The present invention provides a novel large-scale lifting device for automobiles, comprising a drive frame 1 and a lifting belt 4; the lifting belt 4 is arranged along the length of the lifting device, one end of the lifting belt 4 is connected to a drive assembly, and the other end of the lifting belt 4 is connected to a driven pulley assembly 3; the drive assembly includes a drive motor 2-1, a lifting pulley 2-2, and a lifting pulley mounting shaft 2-4; the drive motor 2-1 is mounted on the outside of the drive frame 1, the drive motor 2-1 and the lifting pulley mounting shaft 2-4 are directly connected, the lifting pulley mounting shaft 2-4 is supported and fixed on a motor mounting base 2-6 by two bearing seats 2-3, the lifting pulley 2-2 is connected to the lifting pulley mounting shaft 2-4 through two tensioning sleeves 2-5, and the lifting belt 4 is wound around the lifting pulley 2-2.

[0017] The novel large-scale lifting device for automobiles provided by this utility model has two lifting pulleys 2-2 distributed on each side of the lifting pulley mounting shaft 2-4. The two lifting pulleys 2-2 on each side are integrated into a single unit, and the height of the four lifting pulleys 2-2 can be adjusted simultaneously. The lifting belt 4 is connected to the lifting belt tensioning assembly 5. The drive frame 1 is fixedly connected to the base 7 via an X-shaped support frame 6.
