Description

Technical Field

[0001] This utility model relates to the technical field of lifting mechanisms for transmission machines, and more specifically to a lifting mechanism and a transmission machine. Background Technology

[0002] Currently, lifting transmission machines often use a single slider guide rail to achieve the lifting of the lifting frame. Slider guide rail mechanisms are installed at all four corners of the lifting frame to ensure stable lifting. However, the slider guide rail mechanism has two main drawbacks: firstly, it requires high assembly precision, especially when the lifting stroke is large; secondly, the slider guide rail is expensive, and assembly errors will accelerate the wear of the slider, requiring frequent replacement of the slider.

[0003] Therefore, providing a lifting mechanism and transmission machine that are easy to assemble is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a lifting mechanism and a transmission machine, which reduces assembly difficulty and costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lifting mechanism includes two diagonally arranged slider lifting assemblies and two diagonally arranged cam lifting assemblies, as well as a lifting frame, wherein the lifting frame is horizontally mounted on the two slider lifting assemblies and the two cam lifting assemblies.

[0007] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0008] Replacing the two diagonally opposite slider lifting assemblies with cam lifting assemblies can reduce assembly difficulty, lower equipment costs, reduce wear on parts, and facilitate parts replacement.

[0009] Furthermore, the slider lifting assembly includes a guide rail and a slider, and the lifting frame is mounted on the guide rail via the slider; the cam lifting assembly includes a T-shaped guide rail, a first cam assembly and a second cam assembly, and the lifting frame is slidably connected to the T-shaped guide rail via the first cam assembly and the second cam assembly distributed vertically.

[0010] Furthermore, the first cam assembly includes a first bracket and two first cams, the first bracket being mounted on the lifting frame; both first cams are mounted on the first bracket and spaced apart to fit into the longitudinal plate of the T-shaped guide rail; the second cam assembly includes a second bracket and a second cam, the second bracket being mounted on the lifting frame and located below the first bracket; the second cam is mounted on the second bracket and slidably connected to the inner side of the longitudinal plate.

[0011] A transmission machine includes a transmission machine frame and a lifting mechanism as described above, wherein the transmission machine frame is connected to the guide rail and the T-shaped guide rail adjacent thereto by screws. Attached Figure Description
