Problems solved by technology

[0004] 1) Problems in hydraulic scissor fork lifting: since there is only one fulcrum in the middle part of the scissor fork, the carrying capacity is limited and the stability is poor;
[0005] 2) There are problems in the lifting of a single screw and a screw nut: the support of a single screw is also equivalent to a fulcrum, which also makes the carrying capacity limited and the stability poor; if a single screw needs to achieve the corresponding carrying capacity, Need to increase the size, which will increase the difficulty of processing
[0006] In the process of realizing the present invention, the inventor found that no matter which method is used to lift objects, there is a problem of poor bearing stability

Embodiment 1

[0034] see Figure 1 to Figure 3 As shown, the embodiment of the present invention provides an automatic guided transport vehicle, which can be applied to various occasions where the function of lifting objects needs to be realized, including a vehicle body and a lifting system arranged on the vehicle body. The lifting system includes: a base 1, on which a driving device 2 and at least three sets of lifting mechanisms 3 are arranged, and each set of lifting mechanisms 3 includes a lifting part and a transmission connected to the lifting part. The driving device is connected to the transmission part of each set of the lifting mechanism, the driving device drives the transmission parts of each set of the lifting mechanism to rotate synchronously, and the transmission part drives the lifting part to rise synchronously or drop.

[0035] see figure 1 with figure 2 As shown, in this embodiment, it can be understood that the driving device 2 is a machine that provides power energ...

Embodiment 2

[0068] An automatic guided transport vehicle in an embodiment of the present invention is basically the same in structure as the automatic guided transport vehicle described in Embodiment 1, the difference is that: see Figure 5 As shown, the lifting system is different, specifically: the lifting part includes a lead screw 31, the transmission part includes a lead screw nut 32, and the driving device is transmitted with the lead screw nut 32 through a synchronous belt. When the driving device drives the screw nut to rotate through the synchronous belt, the screw 31 moves upward or downward along the axial direction of the screw nut.

[0069] It can be understood that a bearing 33 is connected to the lead screw nut to support the rotation of the lead screw nut and reduce the frictional force of rotation; in embodiment one, the lifting platform is arranged on the top of the lead screw nut, and since When the nut is rising, the up and down stroke of the lead screw nut is less tha...

Abstract

The embodiment of the invention discloses an automatic guiding transport vehicle, and relates to the technical field of mobile robots. The automatic guiding transport vehicle is good in lifting bearing stability. The automatic guiding transport vehicle comprises a vehicle body and a lifting system arranged on the vehicle body. The lifting system comprises a base. A driving device and at least three sets of lifting mechanisms are arranged on the base. Each set of lifting mechanism comprises a lifting part and a transmission part connected with the lifting part. The driving device is connected with the transmission part of each lifting mechanism, and drives the transmission parts of all sets of lifting mechanisms to rotate synchronously, and the transmission parts drive the lifting parts torise or fall synchronously. The automatic guiding transport vehicle is applicable to various occasions or equipment with the need of lifting objects.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to an automatic guided transport vehicle. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatically guided transport vehicle". AGV belongs to the category of wheeled mobile robot (WMR, Wheeled Mobile Robot). [0003] Since mobile robots can replace or assist human labor to a certain extent, they have been increasingly used in logistics handling or cargo handling and transportation in factories. The automatic guided transport vehicles in existing mobile robots may use hydraulic scissors and forks as Its lifting system lifts up and down, or uses a single screw to rotate around the axial direction as its lifting system to drive the screw nut to rise or fall; but it mainly has the following problems: [0004] 1) Problems in hydraulic scissor fork lifting: since there is only one fulcrum in the middle part of the scissor fork,...
