Example Embodiment

[0038]Example 1:

[0039]A suspension adjustment device for a light-load AGV, comprising an AGV bottom plate 8, a driving wheel suspension device, and a universal wheel suspension device; the AGV bottom plate 8 is provided with a universal wheel suspension device, and the AGV bottom plate 8 is also provided with driving wheels Suspension device, the number of driving wheel suspension devices is 2, the four corners of the AGV bottom plate 8 are provided with universal wheel suspension devices, and the two driving wheel suspension devices are arranged symmetrically at the center of the AGV bottom plate 8. The drive suspension device includes a suspension bracket 1. The fork plate 26, the suspension bracket 1 is a horizontal "U" shape, the suspension bracket 1 is provided with a plate slot 28 on the lower side, and the fork plate 26 is provided with a plate corresponding to the plate slot 28 , A fork plate cover 25 is provided on the upper side of the plug-in plate, the suspension bracket...

Example Embodiment

[0040]Example 2:

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

Example Embodiment

[0042]Example 3:

[0043]A working method for a light-load AGV suspension adjustment device. The structure is as in embodiment 1 and 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. First, carry out a test run, and drive the entire AGV trolley to move through the driving motor. When encountering potholes on the ground, the driving wheel bumps up and down to drive the drive The bracket moves up and down, and the spring stretches to support the shock-absorbing bracket, so that the shock-absorbing bracket makes a small movement around the pin shaft. After running for a certain distance, adjust the adjustment nut up and down according to the shock absorption situation during the movement of the AGV trolley , Including the adjustment nut of 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...
