Embodiment 1

[0039]A suspension adjustment device for light-loaded AGVs, comprising an AGV base plate 8, a drive wheel suspension, and a universal wheel suspension; the AGV base 8 is provided with a universal wheel suspension, and the AGV base 8 is also provided with a drive wheel Suspension device, the number of driving wheel suspension devices is 2, the four corners of the AGV base plate 8 are provided with universal wheel suspension devices, two drive wheel suspension devices are arranged symmetrically at the center of the AGV base plate 8, and the drive suspension device includes a suspension bracket 1. The fork plate 26, the suspension bracket 1 is a horizontal "U" shape, the lower side of the suspension bracket 1 is provided with a board slot 28, and the fork board 26 is provided with a board compatible with the board slot 28 , the upper side of the board is provided with a fork plate cover plate 25, and the suspension bracket 1 is provided with a threaded hole 29, and the threaded ho...

Embodiment 2

[0041] A light-load AGV suspension adjustment device is different from Embodiment 1 in that there are two universal wheel suspension devices, which can be arranged symmetrically along the center line.

Embodiment 3

[0043] A working method for a light-load AGV suspension adjustment device, the structure of which is as in embodiment 1 includes the following steps:

[0044] Install the driving wheel suspension device and the universal wheel suspension device on the AGV base plate 8 according to actual needs, and conduct a trial run first, and drive the entire AGV trolley to move through the driving motor. The bracket moves up and down, and the spring stretches to support the shock absorber, so that the shock absorber moves around the pin shaft in a small scale. After running for a certain distance, adjust the adjustment nut up and down according to the shock absorption during the movement of the AGV trolley. , including the adjustment nuts for the universal wheel and the driving wheel to achieve the best shock absorption effect.

Abstract

The invention discloses a light-load AGV suspension adjusting device and a working method. The light-load AGV suspension adjusting device comprises an AGV bottom plate, a driving wheel suspension device and a universal wheel suspension device. The universal wheel suspension device is arranged on the AGV bottom plate, the driving wheel suspension device is further arranged on the AGV bottom plate;the driving suspension device comprises a suspension support and a fork opening plate; an inserting plate groove is formed in the lower side face of the suspension support; an inserting plate matchedwith the inserting plate groove is arranged on the fork opening plate, and a fork opening plate cover plate is arranged on the upper side of the inserting plate. A threaded hole is formed in the suspension support, an adjusting screw is connected into the threaded hole through threads, a spring sleeve is arranged on the outer side of the adjusting screw in a sleeving mode, a limiting nut is arranged at the upper end of the spring sleeve, and the fork opening plate is connected with one end of the driving support. When an AGV runs to an uneven road surface, the driving wheel can drive a drivingbracket to rotate and float by taking a pin shaft as the center, and meanwhile, the spring sleeve can stretch or contract, so that the adjustment of the driving wheel on the ground pressure is realized, and the friction force between the driving wheel and the ground is further adjusted.

Description

technical field [0001] The invention relates to the field of AGVs, in particular to a light-load AGV suspension adjustment device and a working method. Background technique [0002] The current tape-guided AGV is mainly driven by differential speed. During the operation of the AGV, the driving wheel will slip or hang in the air caused by uneven ground. This puts forward strict requirements for the adjustment and replacement of the suspension installed on the driving wheel. Require. [0003] Chinese patent document (publication number CN 204895083U) discloses a kind of AGV vehicle chassis with suspension mechanism, in more and more miscellaneous dispatching systems, the stability of the operation of AGV is very important to dispatching system, the present invention of Chinese patent is based on The driving force of the driving wheel is large, and it is easy to slip or hang in the air. A light-load AGV suspension adjustment device is designed. The universal wheel and the driv...
