Description

Technical Field

[0001] This utility model relates to the field of intelligent warehousing and logistics equipment technology, and in particular to an integrated, modular, and detachable reversing lifting plate for a four-way shuttle vehicle. Background Technology

[0002] The four-way shuttle is a core piece of equipment in a dense storage system. It can freely switch between horizontal and vertical tracks, a movement that mainly relies on a reversing lifting mechanism.

[0003] Existing lifting slab technology typically suffers from the following problems:

[0004] 1. High Maintenance Costs Due to Integrated Design: Traditional lifting mechanisms typically use a single piece of metal for the lifting plate, which is directly assembled to the drive shaft via rigid fastening methods such as bolts and key connections. The structural design does not consider the need for modular disassembly. When the anti-slip coating on the lifting plate surface, used to enhance friction, wears off due to long-term friction and material impact, or when the plate deforms due to accidental collisions, the entire lifting module must be completely disassembled. This involves disassembling multiple related structures such as drive components and connecting parts, resulting in cumbersome maintenance processes, longer working hours, and increased labor and auxiliary consumable costs. Furthermore, prolonged module downtime affects overall production efficiency, ultimately leading to a significant increase in comprehensive maintenance costs.

[0005] 2. Lack of Flexible Buffering: Traditional lifting mechanisms use a rigid connection between the lifting plate and the drive system, without any flexible buffering structure or shock absorption compensation device. When the lifting plate moves upward during operation and makes instantaneous contact with the track surface, significant mechanical impact loads are generated due to the lack of energy absorption and unloading by the buffer medium. This impact load is not only directly transmitted to core components such as gear transmission mechanisms and cam actuators inside the drive system through the connection structure, but also causes stress concentration and fatigue wear in these precision components under long-term repeated action. In severe cases, it can lead to failures such as gear tooth surface peeling and cam profile deformation, significantly shortening the overall service life of the mechanism and increasing the risk of equipment failure and downtime.

[0006] Therefore, we need to design an integrated, modular, and detachable reversing lifting platform based on a four-way shuttle to solve the problems mentioned above. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the high maintenance cost of the existing integrated reversing lifting plate of the four-way shuttle. This utility model proposes an integrated combination and disassembly reversing lifting plate for the four-way shuttle.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an integrated combination and disassembly type reversing lifting plate for a four-way shuttle, including a base, the base being composed of a first reversing plate and a second reversing plate, with mounting holes and grooves on the surface, and support feet fixed at the four corners below the base, wheel bearing seats being connected to the inner sides of the first reversing plate and the second reversing plate, and the wheel bearing seats being connected to the upper transmission structure, lifting connecting seats being connected to the upper four directions of the base, and connecting plates being connected to the upper part of the lifting connecting seats, with reinforcing ribs correspondingly provided inside the lifting connecting seats.

[0009] Preferably, a lifting plate body is connected above the connecting plate, and an upper contact cover plate is connected above the lifting plate body. The lifting plate body and the connecting plate are connected by a damping movable column. A buffer cross rod is hinged to the inner side of the damping movable column, one end of which is hinged to the lower part of the lifting plate body, and the other end is hinged to the upper part of the connecting plate.

[0010] Preferably, the lifting plate body and the upper contact cover are connected in a modular and detachable manner, and locking structures are provided at the four corners inside the upper contact cover and the lifting plate body.

[0011] Preferably, the locking structure includes a built-in groove disposed inside the lifting plate body. A movable inclined plate is movably connected inside the lifting plate body, and a damper is connected to one side of the movable inclined plate. A pull rod is connected to the other side of the movable inclined plate, and a telescopic spring is wound around the outside of the pull rod. A pull ring is connected to the outside of the lifting plate body. A through groove is provided inside the upper contact cover plate, and a connecting block runs vertically through the through groove. A pressing thread head is fixed above the connecting block, and a fixing inclined block is fixed below the connecting block.

[0012] Preferably, the inclined surfaces on both sides of the fixed inclined block are in contact with the inclined surface on the inner side of the movable inclined plate, and the inclined surfaces slide against each other.

[0013] Preferably, a pulley is connected below the movable inclined plate, and a groove is provided at the bottom of the lifting plate body, and the groove is slidably connected to the pulley.

[0014] Preferably, the damping movable column is a telescopic guide column, which is vertically arranged at the four corners of the connecting plate. The damping movable column includes a guide sleeve fixed above the connecting plate and a guide rod slidably inserted inside the guide sleeve. The top end of the guide rod is fixedly connected to the lower surface of the lifting plate body.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. The lifting plate adopts a modular design, disassembling it into an upper contact cover and a lower base. Quick-release locking mechanisms enable precise assembly and rapid separation of these two parts. When the surface of the lifting plate shows wear and damage due to long-term friction and material impact, operators can replace the upper contact cover independently without disassembling the complex transmission linkage and base structure; simply unlocking the quick-release locking mechanisms significantly simplifies the maintenance process and improves maintenance efficiency by over 80%. Furthermore, to address the varying friction coefficient requirements of different track environments, upper contact covers made of different materials can be flexibly replaced, such as those with rubber pads, polyurethane, or hard alloy, achieving a "one-vehicle-multi-purpose" function adaptable to various operating scenarios. With the coordinated use of a dedicated locking structure, this design features efficient and convenient quick-release assembly, significantly reducing the operational difficulty for operators and providing great convenience for daily maintenance and scenario switching.

[0017] 2. By innovatively designing a damping movable column and a buffer crossbar, and constructing a buffering mechanism that works in tandem with the latter, the impact problem of traditional rigidly connected lifting plates can be effectively solved. When the lifting plate moves upward and makes instantaneous contact with the track, the damping movable column can absorb the impact energy using its own damping characteristics, while the buffer crossbar further relieves the pressure through elastic deformation. The two form a double buffer protection, significantly reducing the mechanical impact load generated at the moment of contact. This design can prevent the impact energy from being directly transmitted to core precision components such as gears and cams inside the drive system, preventing stress concentration, fatigue wear, or deformation damage due to long-term repeated impacts, and significantly extending the overall service life of the mechanism.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] To address the technical challenge of high maintenance costs associated with the existing integrated reversing lifting platform for four-way shuttle vehicles, the following solution is disclosed, specifically as follows: Figures 1-5 As shown:

[0027] An integrated modular reversing lifting plate for a four-way shuttle includes a base 7, which is composed of a first reversing plate 5 and a second reversing plate 6, with mounting holes and grooves. Support feet 12 are fixed at the four corners below the base 7. Wheel bearing seats 4 are connected to the inner sides of the first reversing plate 5 and the second reversing plate 6, and the wheel bearing seats 4 are connected to the upper transmission structure. Lifting connecting seats 2 are connected to the top of the base 7 in four directions, and connecting plates 1 are connected to the top of the lifting connecting seats 2. Reinforcing ribs 3 are respectively provided inside the lifting connecting seats 2.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the traditional single lifting plate is split into a "lower bearing seat" and an "upper contact cover plate 8", which realizes the quick separation of the upper contact cover plate 8 from the lifting plate body 11 without replacing the whole one, thus reducing maintenance costs.

[0029] A lifting plate body 11 is connected above the connecting plate 1, and an upper contact cover plate 8 is connected above the lifting plate body 11. The lifting plate body 11 and the connecting plate 1 are connected by a damping movable column 9. A buffer cross rod 10 is hinged to the inner side of the damping movable column 9. One end of the rod is hinged to the lower part of the lifting plate body 11, and the other end is hinged to the upper part of the connecting plate 1.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, by using the damping movable column 9 and the buffer cross rod 10 in cooperation, the buffering performance of the device is improved, and the rigid connection of the lifting plate will generate a large mechanical impact when it contacts the track. Long-term use will easily lead to fatigue damage of the internal gears or cam mechanism.

[0031] The lifting plate body 11 and the upper contact cover plate 8 are connected in a modular and detachable manner. Locking structures 13 are provided at the four corners inside the upper contact cover plate 8 and the lifting plate body 11.

[0032] The locking structure 13 includes an internal groove 15, which is located inside the lifting plate body 11. A movable inclined plate 23 is movably connected inside the lifting plate body 11. A damper 24 is connected to one side of the movable inclined plate 23, and a pull rod 19 is connected to the other side of the movable inclined plate 23. A telescopic spring 20 is wound around the outside of the pull rod 19. A pull ring 18 is connected to the outside of the lifting plate body 11. A through groove 25 is provided inside the upper contact cover plate 8. A connecting block 16 is vertically passed through the through groove 25. A pressing thread head 14 is fixed above the connecting block 16, and a fixing inclined block 17 is fixed below the connecting block 16.

[0033] Specifically, such as Figure 4 , Figure 5 As shown, the specially designed locking structure 13 enables efficient and quick assembly and disassembly of the upper contact cover 8 and the lifting plate body 11, eliminating the need for complex operating procedures and auxiliary tools. This design significantly simplifies the installation, disassembly, and maintenance steps for workers, greatly reduces operational difficulty, and brings great convenience to daily operations. Simultaneously, this structure effectively enhances the overall practicality of the device, making it more adaptable to different operating scenarios and further strengthening its flexible adjustment capabilities during use to meet diverse application needs.

[0034] The inclined surfaces on both sides of the fixed inclined block 17 are in contact with the inclined surface on the inner side of the movable inclined plate 23, and the inclined surfaces slide against each other;

[0035] The damping movable column 9 is a telescopic guide column, which is vertically set at the four corners of the connecting plate 1. The damping movable column 9 includes a guide sleeve fixed above the connecting plate 1 and a guide rod slidably inserted inside the guide sleeve. The top end of the guide rod is fixedly connected to the lower surface of the lifting plate body 11.

[0036] In this embodiment, when the upper contact cover plate 8 needs to be replaced, the upper contact cover plate 8 is aligned with the installation position of the lifting plate body 11. The operator presses down the top pressing thread head 14. The pressing thread head 14 drives the connecting block 16 and the end fixing inclined block 17 to move vertically downward. Since the bottom of the base 7 is designed as a trapezoidal inclined surface, when it contacts the corresponding inclined surfaces of the left and right movable inclined plates 23, it will convert the vertical downward force into a horizontal component force. This horizontal component force overcomes the resistance of the damper 24 and pushes the left and right support feet 12 to slide horizontally outward along the bottom slide groove 21 and pulley 22, thereby making room for the central channel. When the widest part of the fixing inclined block 17 completely passes the locking position of the movable inclined plate 23 and continues to descend to the bottom, the movable inclined plate 23 quickly rebounds inward under the restoring force of 34. At this time, the locking teeth of the movable inclined plate 23 enter and lock into the neck position above the fixed inclined block 17. Since the locking block blocks the retraction path of the locking head, the vertical limiting and fixing are achieved, and the locking connection between the upper and lower components is completed.

[0037] Secondly, when disassembly is required, the operator pulls the pull ring 18 located on the side outward. Through the internal connecting mechanism, the right movable inclined plate 23 overcomes the elastic force of the damper 24 and moves horizontally outward. As the movable inclined plate 23 moves outward, the retaining teeth that were originally stuck above the fixed inclined block 17 are removed, no longer obstructing the upper path of the fixed inclined block 17. At this time, there is no mechanical interference between the fixed inclined block 17 and the movable inclined plate 23. The operator can then grasp the pressing thread head 14 and lift it vertically upward, causing the fixed inclined block 17 to disengage from the cavity, completing the separation.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
