Problems solved by technology

[0005] 1) In the form of multiple screw jacking together, the diameter of the screw is usually small. When it is used for AGV jacking, it not only bears the axial force but also must bear a certain radial force when the AGV is traveling or the cargo is unbalanced. Force, does not meet the use specifications of the standard lead screw
Moreover, the adjustment, installation and coordination of multiple screw screws are more complicated and require a certain technical foundation to complete.
[0006] 2) The diameter of the screw in the jacking form of the hollow screw is relatively thick, which increases the bearing of the screw to the radial force to a certain extent, but the long-term radial force of the hollow screw has an impact on the service life of the hollow screw , and the processing cost of the hollow lead screw is high
[0007] 3) The wedge lifting mechanism is used in conjunction with the wedge block and the linear drive device, wherein the linear drive device is arranged on one side of the wedge block, resulting in a large space occupied by the AGV chassis and the need to add some auxiliary structures, thus limiting the small size of the AGV trend

Abstract

The invention discloses a lifting mechanism, a lifting and rotating mechanism and an automatic guided vehicle, belonging to the technical field of warehousing and logistics. The lifting mechanism includes a lifting frame, a guide rail top plate and a drive belt, and at least two diagonal brace guide rails are evenly arranged on the vertical side wall of the lifting frame along the circumferential direction; the guide rail top plate includes a first slider, and the first The slider is slidably connected with the brace guide rail; the driving belt is configured to drive the top plate of the guide rail along the circumferential direction of the lifting frame to move. Both the lifting and rotating mechanism and the automatic guided vehicle include the above-mentioned lifting mechanism. The lifting mechanism of the invention has the advantages of simple structure, no partial load, small space occupation and stable lifting.

Description

technical field [0001] The invention relates to the technical field of warehousing and logistics, in particular to a lifting mechanism, a lifting and rotating mechanism and an automatic guided vehicle. Background technique [0002] Lifting mechanisms are widely used in industrial equipment in various industries, such as automatic guided vehicles (AGV for short) in the field of logistics and automated warehousing. [0003] The lifting mechanism of the existing AGV includes a screw lifting mechanism and a wedge lifting mechanism. The screw lifting mechanism can adopt the form of hollow screw jacking or the form of jacking up by multiple screw screws. Usually multiple lead screws are jointly lifted to realize the simultaneous action of multiple lead screws through the combination of motors, reducers, gears, etc. [0004] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] 1) In the for...
