Description

Technical Field

[0001] The utility model relates to the technical field of warehouse management equipment, and more particularly to a stacker overhead rail guide device. Background Art

[0002] With the rapid development of the materials and warehousing industry, facing the large-scale movement of goods, stacker cranes are more and more widely used in automated warehouses. They automatically stack goods through the coordination of driving equipment, carrying equipment and guiding equipment, which greatly improves work efficiency compared to manual stacking by workers.

[0003] The overhead rail device is a common stacker component, and the guide device is an important part of the overhead rail device. The common overhead rail guide device has a simple structure and only guides and restricts the movement of the equipment through side walls in a specific direction, thereby providing guidance. During operation, if the carrying equipment tends to deviate, its side end will directly contact the restriction structure and be restricted from moving, thereby changing to the correct moving direction. This correction method causes large wear and tear, and long-term use can easily cause simple damage to the moving structure and the wire structure, resulting in gaps, affecting the stability of the mobile equipment during movement; moreover, as a mechanical motion device, the overhead rail device requires regular maintenance. During daily maintenance, the track and the mobile equipment need to be lubricated to ensure stable coordination during movement. The existing stacker overhead rail guide device does not have an automatic lubrication function, and workers need to use the equipment to climb to a high place to maintain the overhead rail guide device, which is inefficient and poses a safety hazard; in addition, common warehouses are not set up as dust-free environments. As long-term work progresses, foreign matter such as dust in the air will fall into the guide structure. As the use time increases, dust gradually accumulates, which will affect the coordination between the mobile equipment and the guide device, requiring timely cleaning, which is more troublesome.

[0047] In summary, when the overall device is in use (or running):

[0048] The stacker is loaded onto the mobile frame 2, and the movement of the mobile frame 2 is controlled by an external power device so that the mobile frame 2 cooperates with the track body 1. Under the guidance of the track body 1, the mobile frame 2 moves with the stacker to perform the stacking work, and when the mobile frame 2 cooperates with the track body 1, the mobile frame 2 contacts the track body 1 through the supporting wheels 3, so that the track body 1 supports the mobile frame 2, and the mobile frame 2 provides a limiting ability through the limiting frame 4 to limit the movement of the mobile frame 2. The two sides of the mobile frame 2 contact with the limiting frame 4 through the side contact wheels 5, thereby limiting the horizontal movement of the mobile frame 2, and the mobile frame 2 contacts with the limiting frame 4 through the upper contact wheels 6, thereby providing longitudinal restriction to the mobile frame 2, and when the mobile frame 2 moves, the side contact wheels 5 and the upper contact wheels 6 can both rotate to reduce the distance between the mobile frame 2 and the limiting frame 4 The cleaning brush 13 and the cleaning scraper 14 are moved by the extension frame 12 to clean the dust in the track body 1 and push the foreign objects to move. The large foreign objects or attachments that the cleaning brush 13 cannot clean will be cleaned by the cleaning scraper 14, so that they will first contact with the nearby track surface before the supporting wheel 3 of the moving frame 2 to clean the track, and avoid foreign objects affecting the cooperation between the moving frame 2 and the track body. In addition, the baffle 15 blocks the inner side of the track body 1 to prevent foreign objects from falling directly when being pushed. Instead, the foreign objects are pushed to one end of the track body, collected and cleaned through the dust exhaust pipe 16, and then collected through the collection box 17 for easy cleaning.
