Technical Field

[0001] The utility model belongs to the technical field of four-way shuttle vehicles, and in particular relates to a synchronous lifting mechanism of a four-way shuttle vehicle. Background Art

[0002] In the field of modern machinery, particularly in the design and manufacture of lifting gearbox mechanical systems for four-way shuttles, traditional solutions typically employ a single lifting motor to simultaneously control both lifting and longitudinal travel functions. This design utilizes a shaft drive to achieve lifting. While this solution achieves functional requirements to a certain extent, its shortcomings have become increasingly apparent in practical applications, becoming a key factor limiting system performance and production efficiency.

[0003] Specifically, the main defects of traditional solutions are reflected in the following aspects:

[0004] Large number of parts and complex assembly process: Since the lifting and walking functions need to be met at the same time, the number of parts inside the system increases significantly, which not only increases the manufacturing cost, but also makes the assembly process extremely complicated and requires extremely high skills from workers.

[0005] High-precision requirements and dimensional control challenges: To ensure stable system operation, the matching accuracy between components must be extremely high, which directly increases the difficulty of processing and complicates dimensional control. Once the component precision does not meet the standard, it is easy to cause assembly problems, resulting in high rework and repair rates, seriously affecting production efficiency and cost control.

[0006] Assembly difficulties caused by structural complexity: The complex structural design in traditional solutions not only increases the difficulty of assembly, but also limits the maintainability and scalability of the system, which is not conducive to subsequent product upgrades and technological innovations.

[0007] To this end, the utility model designs a four-way shuttle synchronous lifting mechanism that realizes independent lifting control through a motor and a lifting transmission shaft. Utility Model Content

[0010] A jacking gear transmission pair is provided in each of the jacking gear boxes. The first-stage gear of the jacking gear transmission pair in the jacking gear box on one side is connected to the output shaft of the reducer, and the reducer is connected to the jacking drive motor; the secondary gear and the final gear of the jacking gear transmission pair are respectively connected to a group of jacking wheel assemblies through shafts.

[0011] Further preferably, the lifting synchronous transmission shaft adopts a split structure, and the two split lifting synchronous transmission shafts are connected by a telescopic cross coupling.

[0012] Further preferably, the jacking wheel assembly includes two connecting rods arranged in parallel, a support shaft installed at the lower end of the connecting rod, a jacking wheel installed on the support shaft, the jacking wheel cooperates with the oblong jacking groove on the jacking beam, the connecting rod located on the outside is connected to the jacking bracket through the support shaft, and the connecting rod on the inside is connected to the secondary gear or final gear of the jacking gear transmission pair through the shaft.

[0013] Further preferably, linear guide rail assemblies are provided between the two ends of the jacking gear box connecting plate and the jacking beam.

[0014] The advantages and technical effects of this utility model are as follows: Through a carefully designed vehicle frame and lifting mechanism, this utility model achieves overall stability and safety during the operation of the shuttle. The lifting mechanism is cleverly positioned on the Y-axis travel wheel side, optimizing space utilization and closely integrating lifting and travel functions, improving operational efficiency. The coordinated operation of the lifting beam and lifting wheel assembly ensures stable travel and precise lifting of the shuttle. The use of a synchronous lifting drive shaft and a telescopic cross coupling further ensures the synchronization and stability of the lifting action on both sides, enhancing the adaptability and flexibility of the equipment.

[0015] The jacking wheel assembly design incorporates a parallel link and support shaft structure, ensuring stable mounting and precise alignment with the oblong jacking slots on the jacking beam, enabling smooth and accurate lifting. Furthermore, the outer link is connected to the jacking bracket for enhanced structural stability, while the inner link is directly connected to the jacking gear drive pair, ensuring efficient power transmission.

[0016] In addition, the linear guide rail assembly added between the jacking gearbox connecting plate and the jacking beam greatly improves the guiding accuracy and stability during the jacking process, reduces friction, and ensures smooth and unobstructed jacking action.

[0017] In summary, the four-way shuttle synchronous lifting mechanism, through a series of optimized designs and technical features, achieves precise control of the shuttle's lifting motion, improving the stability, synchronization, and reliability of the lifting process. It also optimizes space utilization, enhances the adaptability and flexibility of the equipment, reduces maintenance costs, and improves economic efficiency. Overall, this synchronous lifting mechanism provides a strong guarantee for the efficient, stable, and reliable operation of the shuttle, making it an indispensable component of modern logistics and warehousing systems.

[0026] Each of the jacking gearboxes is equipped with a jacking gear transmission pair 2-6. Through the deceleration and torque-increasing effects of the gear transmission pair, precise control of the jacking wheel assembly is achieved, improving the sensitivity and accuracy of the jacking action. The first gear 2-7 of the jacking gear transmission pair in the jacking gearbox on one side is connected to the output shaft of the reducer 4, which is connected to the jacking drive motor 5, achieving efficient power transmission and conversion. The deceleration effect of the reducer also improves the smoothness and controllability of the jacking action. The secondary gear 2-7 and the final gear 2-8 of the jacking gear transmission pair are each connected to a set of jacking wheel assemblies via shafts. This achieves synchronous control of the two sets of jacking wheel assemblies, ensuring the synchronization of the jacking action.

[0027] In summary, the four-way shuttle synchronous jacking mechanism achieves precise control of the shuttle jacking action through a series of carefully designed technical features, improves the stability, synchronization and reliability of the jacking, and provides a strong guarantee for the efficient operation of the shuttle.

[0028] Further preferably, the lifting synchronous transmission shaft adopts a split structure, and the two split lifting synchronous transmission shafts are connected by a telescopic cross coupling 6. First, the cross coupling, with its compact structure and optimized space utilization, enables effective and flexible connection of the transmission shafts in a limited space, meeting the shuttle's demand for efficient space utilization.

[0029] Secondly, the telescopic cross coupling ensures the stability and synchronization of the transmission system.
