[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1 and Figure 2 shown, a secondary lifting structure of a human upward three-way stacker includes a secondary gantry 1, a fork carriage 2, a composite roller assembly 3, forks 4, and a telescopic mechanism 5. The secondary gantry 1 is used to provide stable support. The secondary gantry 1 is made of high-strength steel, with a simple and reasonable design, providing stable support for the entire secondary lifting system. The fork carriage 2 is fixed on the secondary gantry 1. The fork carriage 2 is formed by integral plate cutting, welding, with a strong structure and uniform stress. The fork carriage and the secondary gantry are fixed by a high-strength connection method to ensure the firmness and reliability of the connection. The composite roller assembly 3 is installed at one end of the fork carriage 2. The composite roller assembly 3 includes rollers 31. The composite roller assembly 3 can adjust the gap between the rollers 31 and the walking guide rail. The rollers 31 in the composite roller assembly 3 are made of wear-resistant materials to ensure smooth operation on the guide rail, allowing the gap between the rollers 31 and the guide rail to be adjusted according to actual needs, ensuring the smooth operation of the rollers 31 on the guide rail, and further enhancing the stability of the lifting of the fork carriage 2. The forks 4 are detachably arranged on the fork carriage 2. The forks 4 are customized according to the size and shape of the goods to ensure the stability and safety of the goods during handling. The forks 4 are fixed on the fork carriage 2 by bolts or other connection methods, facilitating disassembly and replacement. The telescopic mechanism 5 is connected to the fork carriage 2 and is used to drive the fork carriage 2 to lift and lower.

[0025] In the above solution, the secondary gantry 1 provides a strong structural support, keeping the stacker stable during operation. The fork carriage 2 is fixed on the secondary gantry 1 to ensure the position and stability of the forks 4. The composite roller assembly 3 ensures the smooth movement and docking of the stacker during walking by adjusting the gap between the rollers 31 and the guide rail, adapting to different track conditions. The detachable design of the forks 4 makes replacement and maintenance more convenient. The telescopic mechanism 5 can adjust the height of the forks through its lifting and lowering function, facilitating stacking and picking operations, and improving the flexibility and efficiency of the stacker.

[0026] In a possible implementation manner, the composite roller assembly 3 in the secondary lifting structure of the human upward three-way stacker adjusts the gap between the rollers 31 and the guide rail through nuts and bolts.

[0027] In the above solution, the composite roller assembly 3 adopts the adjustment method of nuts and bolts, which can accurately control the gap between the roller 31 and the guide rail. This design enables the stacker to adjust according to different guide rail conditions during walking, ensuring smooth operation, reducing the wear of the guide rail and rollers to a certain extent, and improving the service life of the equipment.

[0028] In a possible implementation, the fork 4 in the auxiliary lifting structure of the man-up three-way stacker is fixedly connected to the fork rack 2 by bolts. In this technical solution, the fork 4 is fixedly connected by bolts, which can ensure the stable connection between the fork and the fork rack 2. This fixing method not only ensures the stability of the fork during use but also facilitates disassembly and replacement when needed, improving the maintenance convenience and service efficiency of the equipment.

[0029] The telescopic mechanism 5 in the auxiliary lifting structure of the man-up three-way stacker includes an auxiliary lifting oil cylinder 51. The fixed end of the auxiliary lifting oil cylinder 51 is fixed inside the auxiliary gantry 1, and the piston rod of the auxiliary lifting oil cylinder 51 is connected to the fork rack 2. In this technical solution, as part of the telescopic mechanism 5, the fixed end of the auxiliary lifting oil cylinder 51 is fixed inside the auxiliary gantry 1, providing stable support. The connection between the piston rod and the fork rack 2 enables the auxiliary lifting oil cylinder 51 to achieve the lifting and lowering action of the fork rack 2 through hydraulic power, thereby realizing the lifting function of the stacker. This design improves the operation flexibility and efficiency of the fork 4. The auxiliary lifting oil cylinder 51 is responsible for driving the lifting and lowering of the fork rack 2. The auxiliary lifting oil cylinder 51 is made of high-strength materials and precision machining processes, with sufficient thrust and stability. The piston rod of the auxiliary lifting oil cylinder 51 is connected to the fork rack 2, and the lifting and lowering of the fork rack 2 are achieved through the telescopic movement of the auxiliary lifting oil cylinder 51. The pipeline design of the auxiliary lifting oil cylinder 51 is reasonable, ensuring the smooth flow of oil and the stable operation of the auxiliary lifting oil cylinder 51.

[0030] The auxiliary lifting oil cylinder 51 is installed inside the auxiliary gantry 1 through fixed bolts, making the fixation of the auxiliary lifting oil cylinder 51 more firm and capable of withstanding greater lifting and lowering forces. The bolt fixation method is also convenient for installation and disassembly, facilitating the maintenance and replacement of the auxiliary lifting oil cylinder 51. The inlet and outlet ports of the auxiliary lifting oil cylinder 51 are connected with hydraulic pipelines. The inlet and outlet ports of the auxiliary lifting oil cylinder 51 are connected through the hydraulic pipeline 8 to form a complete hydraulic system. The design of the hydraulic pipeline 8 ensures the flow of hydraulic oil inside the auxiliary lifting oil cylinder 51, providing sufficient power sources to ensure the normal operation of the auxiliary lifting oil cylinder 51. Through the control of the hydraulic system, precise control of the telescopic action of the auxiliary lifting oil cylinder 51 can be achieved, thereby realizing the lifting and lowering function of the fork rack 2 and improving the operation performance and working efficiency of the stacker.

[0031] This structure further includes a chain assembly 7 with a safety factor of over five times. The chain assembly 7 uses high-strength chains and has a safety factor of over five times, ensuring stable operation even in extreme cases and further enhancing the safety of the system.

[0032] A stacker is also provided, including the above-mentioned auxiliary lifting structure of the man-up three-way stacker.

[0033] In the specific implementation process, first, install the auxiliary gantry 1 on the transmission shaft of the attachment gearbox of the three-way stacker and lock it with bolts to ensure the stability and perpendicularity of the auxiliary gantry 1. Immediately afterwards, install the auxiliary lifting cylinder 51 inside the auxiliary gantry 1 with two cylinder fixing bolts 6. Then, install the composite roller assembly 3 at the shaft part of the rear roller 31 of the fork carriage 2 formed by integral plate cutting, welding. Next, fix the fork carriage 2 on the auxiliary gantry 1, and adjust the clearance between the roller 31 and the guide rail by adjusting the mechanism on the composite roller 31 to ensure the smooth operation of the roller 31 on the guide rail and ensure the firm and reliable connection. Fix the customized fork 4 on the fork carriage 2, which is customized to meet the handling requirements of different goods, ensure the tight fit between the fork 4 and the fork carriage 2 and install the limit bolts. Install the chain assembly with a safety factor of over five times to provide additional guarantee for the safe operation of the system. Finally, connect the pipeline of the auxiliary lifting cylinder 51, and realize the lifting and lowering of the fork carriage by controlling the telescopic movement of the auxiliary lifting cylinder 51. During the lifting and lowering process, the composite roller assembly 3 rolls on the guide rail to provide support and guidance for the lifting and lowering of the fork carriage 2. Through the assembly and operation of the above steps, the auxiliary lifting system of the man-up three-way stacker can achieve stable handling and lifting of goods, while simplifying the structure, reducing the assembly difficulty, and enhancing the stability of the lifting of the fork carriage 2.
