Description

Technical Field

[0001] The utility model belongs to the technical field of stackers, in particular to a lane-changing device for stackers. Background Art

[0002] The invention patent with patent number 202211363507.4 discloses a stacker aisle replacement system and a stacker vertical warehouse. The stacker aisle replacement system includes a ground translation module, a first mobile slide module and a second mobile slide module. The ground translation module includes a first slide rail. The first drive component of the first mobile slide module drives the first sliding plate to slide along the first slide rail. The second slide rail is arranged on the first sliding plate and is parallel to the extension direction of the aisle. A accommodating space for the stacker is formed on the mobile frame. The docking rail is arranged on the mobile frame. The second drive component drives the mobile frame to slide along the second slide rail so that the docking rail docks with the shelf rail arranged in the aisle. The stacker can move between the aisle and the accommodating space along the docking rail and the shelf rail after docking.

[0003] This patent disclosure has certain flaws. After the first drive assembly drives the first movable slide module along the first slide rail to a position directly opposite the aisle where the stacker is located, the second drive assembly is required to drive the second movable slide module along the second slide rail. The stacker then moves along the docked overhead and floor rails into the accommodation space of the movable frame. The movement and docking process of the second movable slide module is overly complex and time-consuming, affecting the efficiency of the stacker in changing aisles. Summary of the Invention

[0026] The travel wheel base 8 consists of two long mounting plates 8a, two wide mounting plates 8b, and a top mounting plate 8c. A rotatable motor output shaft 10 is mounted within the travel wheel base 8, onto which the rubber-coated wheel 9 is mounted. Eccentric adjustment seats 11 are located at each end of the motor output shaft 10. These seats house two bearings 12, which are connected by bearing spacers 13. The eccentric adjustment seats 11 are mounted on the outside of the wide mounting plates 8b via the bearings 12. A correction sleeve 14 is also mounted on the motor output shaft 10, secured to it via spacers 15.

[0027] A travel motor 16 for driving the motor output shaft 10 is provided on the outside of the installation wide plate 8b. A reducer 17 is provided at one end of the drive shaft of the travel motor 16. The output end of the reducer 17 is connected to one end of the motor output shaft 10. A motor connecting plate 18 is provided in front of the reducer 17. An eccentric seat collar 19 is provided in front of the motor connecting plate 18.

[0028] Brush mounting brackets 21 are provided on both the front and rear sides of the travel wheel seat 8. Brushes 20 are mounted on the front and rear sides of the travel wheel seat 8 through the brush mounting brackets 21. Two symmetrically mounted guide wheels 22 are provided below the brush mounting brackets 21. During the movement of the travel wheel assembly, the guide wheels 22 cooperate with the lane change track 3 to accurately guide the steel frame platform 4 along the lane change track 3. Two sets of travel drive wheel assemblies 6 are mounted on the front side of the steel frame platform 4. The front side of the brush mounting brackets 21 is also equipped with a brush anti-collision block 23 to prevent accidental collisions.

[0029] like Figure 3 As shown, the traveling driven wheel group 7 includes a traveling wheel seat 8 and a rubber-coated wheel 9. When the traveling driving wheel drives the steel frame platform 4 to move forward and backward along the tunnel ground rail 3, the traveling driven wheel group 7 follows the traveling driving wheel group 6 to move forward and backward.

[0030] The travel wheel base 8 consists of two long mounting plates 8a, two wide mounting plates 8b, and a top mounting plate 8c. A rotatable motor output shaft 10 is mounted within the travel wheel base 8, onto which the rubber-coated wheel 9 is mounted. Eccentric adjustment seats 11 are located at each end of the motor output shaft 10. These seats house two bearings 12, which are connected by bearing spacers 13. The eccentric adjustment seats 11 are mounted on the outside of the wide mounting plates 8b via the bearings 12.
