A driving mounting plate 200 is arranged in the chassis 100, and the driving mounting plate 200 is connected to the chassis 100 through a connecting assembly 600. The traction assembly is arranged on one side of the driving mounting plate 200. The traction assembly includes a pair of rollers 300, and the rollers 300 are installed on one side of the bottom of the driving mounting plate 200. The lifting assembly 400 is arranged on one side of the driving mounting plate 200 close to the rollers 300, and the driving assembly is arranged on the other side of the driving mounting plate 200. The driving assembly includes a pair of driving wheels 500, and the driving wheels 500 are installed on the bottom of the driving mounting plate 200 away from the side of the lifting assembly 400, wherein the output shaft of the lifting assembly 400 can abut against one side of the driving mounting plate 200 to lift the driving wheel 500. The driving mounting plate 200 of the lifting device of the latent traction AGV driving wheel 500 of the embodiment of the utility model is swingably connected to the chassis 100 through the connecting assembly 600. When the AGV trolley fails during transportation and the driving wheel 500 is locked, the lifting assembly 400 operates, and the output shaft of the lifting assembly 400 extends out and abuts against one side of the driving mounting plate 200, so that one side of the driving mounting plate 200 is subjected to force, that is, a pair of rollers 300 of the traction assembly are in contact with the ground and apply pressure, while a pair of driving wheels 500 arranged on the other side of the driving mounting plate 200 are tilted and gradually leave the ground, and then the traction assembly drives the rollers 300 and the entire AGV trolley to drive away from the fault area.

[0049] The device for lifting the driving wheel 500 of the latent traction AGV in the embodiment of the utility model has a simple structure and occupies a small space, and can quickly lift the driving wheel 500 of the AGV trolley, thereby improving the working efficiency of the production system.

[0050] Furthermore, the connecting assembly 600 includes a rotating shaft mounting seat 610 and a rotating shaft 620. The rotating shaft mounting seat 610 is mounted on the side wall of the chassis 100. The rotating shaft 620 is connected with the rotating shaft mounting seat 610 in cooperation, and the rotating shaft 620 is arranged on the driving mounting plate 200. In other words, when the driving mounting plate 200 is swingably connected to the chassis 100 through the connecting assembly 600, the driving mounting plate 200 swings around the rotating shaft 620 as the central axis, so that the driving assembly disposed away from the lifting assembly 400 can be relatively tilted, and then the driving wheel 500 can be lifted off the ground.

[0051] Furthermore, the connecting assembly 600 further includes a self-lubricating sleeve 630, which is disposed between the rotating shaft mounting seat 610 and the rotating shaft 620. In other words, the self-lubricating sleeve 630 is disposed between the rotating shaft mounting seat 610 and the rotating shaft 620, and the self-lubricating sleeve 630 can ensure the smoothness and fluidity of the driving mounting plate 200 during the swinging process.

[0052] Further, the chassis 100 is formed with a cavity 110, the drive mounting plate 200 is arranged in the cavity 110, the side wall of the chassis 100 extends into the cavity 110 to form a reinforcing rib 120, and the shaft mounting seat 610 is fixedly connected to the reinforcing rib 120. The reinforcing rib 120 is provided on the chassis 100 to facilitate the installation of the shaft mounting seat 610, and the strength of the chassis 100 can be improved by providing the reinforcing rib 120. Preferably, two shaft mounting seats 610 can be provided correspondingly, for example, to further ensure the stability of the drive mounting plate 200 when it swings.

[0053] Furthermore, a pair of hollow grooves 130 are formed on the side wall of the chassis 100, and the driving wheel 500 is arranged at the corresponding position of the hollow groove 130. That is to say, by providing a pair of hollow grooves 130 on the chassis 100, the weight of the device and the lightweight of the AGV can be reduced, and further, by providing the driving wheel 500 at the corresponding position of the hollow groove 130, it is convenient for the staff to observe the working state of the driving wheel 500, and then the locking situation of the driving wheel 500 can be observed in time, thereby further improving the working efficiency of the production system.

[0054] Further, a first clearance groove 210 for installing the jacking assembly 400 is formed on one side of the driving mounting plate 200. The jacking assembly 400 includes a jacking motor 420 mounting plate 410, a jacking motor 420 and a jacking bracket 430. Both ends of the jacking motor 420 mounting plate 410 are connected to both sides of the chassis 100. The jacking motor 420 is installed at the bottom of the jacking motor 420 mounting plate 410, and the jacking bracket 430 is connected to the driving mounting plate 200. In other words, the first clearance groove 210 is provided on one side of the driving mounting plate 200, so that a part of the jacking assembly 400 can be arranged on the top of the driving mounting plate 200, and the other part can be arranged at the bottom of the driving mounting plate 200, thereby reducing the installation space.

[0055] Furthermore, the lifting bracket 430 includes an abutment portion 431 and two connection portions 432. The abutment portion 431 is arranged on the opposite side of the output shaft of the lifting motor 420. The two connection portions 432 are respectively arranged on both sides of the abutment portion 431 and extend upward to connect with the bottom of the driving mounting plate 200. That is to say, when the AGV trolley fails during transportation, the output shaft of the lifting assembly 400 extends out to abut against the abutment portion 431 of the lifting bracket 430 and continues to extend downward. The lifting bracket 430 is subjected to a downward force, and the connection portion 432 of the lifting bracket 430 is connected to one side of the bottom of the driving mounting plate 200. This force drives one side of the driving mounting plate 200 to move downward, and the entire driving mounting plate 200 rotates and swings around the rotating shaft 620 as the central axis, and then the driving assembly located on the other side of the driving mounting plate 200 moves upward, that is, the driving wheel 500 of the driving assembly tilts upward and leaves the ground; then, the traction assembly and the roller 300 drive the entire AGV trolley away from the fault area.

[0056] Further, an extension frame 220 is provided at one side of the bottom of the drive mounting plate 200, and the roller 300 is installed on the extension frame 220. By providing the extension frame 220, a roller 300 of a smaller size can be provided, so that at least a portion of the roller 300 is exposed outside the side wall of the chassis 100 and supports the chassis 100.

[0057] Further, a second clearance groove 230 for installing the driving component is formed on the other side of the driving installation plate 200. That is, by arranging the second clearance groove 230 on the other side of the driving installation plate 200, it is convenient to connect the driving circuit, the wire and the driving component.

[0058] The utility model also provides an AGV trolley, which includes the above-mentioned device for lifting the latent traction AGV drive wheel 500. When the AGV trolley fails during transportation and the drive wheel 500 is locked, the lifting assembly 400 of the device for lifting the latent traction AGV drive wheel 500 operates, and the output shaft of the lifting assembly 400 extends and abuts against one side of the drive mounting plate 200, so that one side of the drive mounting plate 200 is subjected to force, that is, a pair of rollers 300 of the traction assembly contact the ground and apply pressure, and a pair of drive wheels 500 arranged on the other side of the drive mounting plate 200 are tilted and gradually separated from the ground, and then the traction assembly drives the rollers 300 and the entire AGV trolley to drive away from the fault area. The AGV trolley of the utility model has the advantage of high production efficiency.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
