Description

Technical Field

[0001] This utility model relates to the field of four-way shuttle technology, and in particular to a lifting guide structure for a pallet-type four-way shuttle. Background Technology

[0002] In automated warehouses, intelligent shuttle transport vehicles play a crucial role. These vehicles can be used in various high-density storage environments, with aisles designed to be of arbitrary length, maximizing overall warehouse storage capacity. Furthermore, they eliminate the need for forklifts to enter the aisles, enhancing safety. Leveraging the advantage of not requiring forklifts to enter the aisles, combined with the rapid movement of the vehicles within the aisles, warehouse operational efficiency is significantly improved. The four-way shuttle is an intelligent material handling device integrating four-way travel, on-the-spot track changing, automated material handling, intelligent monitoring, and dynamic traffic management. It can travel along longitudinal or transverse tracks on intersecting tracks to reach any designated storage location in the warehouse, unrestricted by site limitations, adaptable to various working environments, and freely dispatchable at the terminal, achieving fully automated, unattended operation. When changing direction, the four-way shuttle typically achieves a 90-degree change through the vertical movement of its own body.

[0003] In the existing technology, the lifting and guiding mechanism of the four-way shuttle car usually adopts linear guide rails, which requires high precision in the machining of the car body. At the same time, the cost of purchasing linear guide rails is also high, the guiding stability is poor, and mechanical jamming is prone to occur. The maintenance is also inconvenient. Therefore, how to provide a reversing lifting and guiding mechanism with high stability and low cost is an urgent technical problem to be solved.

[0004] Therefore, it is necessary to provide a lifting and guiding structure for a pallet-type four-way shuttle to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention.

[0024] Please see Figure 1-5 This utility model provides a lifting and guiding structure for a pallet-type four-way shuttle, including a car body 1. The car body 1 has two mounting slots 5 symmetrically distributed at both ends of the car body 1. Each mounting slot 5 contains a lifting car body 3 that can be lifted and moved. Roller bearings 4 are fixed to the outer wall of the lifting car body 3. Guide grooves 2 are formed on the side wall of the car body 1, arranged along the lifting direction of the lifting car body 3 and adapted to the rolling of the roller bearings 4. Multiple roller bearings 4 are distributed on multiple sides of the lifting car body 3. Multiple guide grooves 2 are provided, each corresponding to one of the roller bearings 4. This utility model achieves lifting and moving... Roller bearings 4 are installed on the vehicle body 3. Guide grooves 2 are opened on the side of the vehicle body 1 where lifting is not required. The roller bearings 4 are inserted into the guide grooves 2 to move and lift. Thus, the lifting and lowering movement of the vehicle body 3 is guided by the cooperation of the guide grooves 2 and the roller bearings 4. By installing roller bearings 4 in different parts of different lifting vehicle bodies 3, multiple degrees of freedom of the lifting vehicle body 3 are restricted, so that the lifting vehicle body 3 can only move up and down along the guide grooves 2. The overall guiding structure is relatively simple, with low manufacturing and usage costs. At the same time, this guiding structure has low requirements for the machining precision of the vehicle body. The roller bearings 4 roll in the guide grooves 2 to guide the lifting vehicle body 3, which is not prone to jamming. It is easy to install and maintain.

[0025] Further as Figure 2 , Figure 3 and Figure 5As shown, it is worth noting that the side wall of the lifting vehicle body 3 is rotatably connected to a wheel 6 located at the bottom of the lifting vehicle body 3, and multiple wheels 6 are provided; in actual operation, a drive motor is installed inside the vehicle body 1 to drive the wheels 6 to rotate, and the drive motor drives the wheels 6 to rotate synchronously, and the multiple wheels 6 drive the vehicle body 1 to move the items it carries.

[0026] This solution has the following working process: By installing roller bearings 4 on the lifting vehicle body 3, a guide groove 2 is opened on the side of the vehicle body 1 that does not need to be lifted. The roller bearings 4 are inserted into the guide groove 2 to move and lift. Thus, the lifting and lifting movement of the lifting vehicle body 3 is guided by the cooperation of the guide groove 2 and the roller bearings 4. By installing roller bearings 4 in different parts of different lifting vehicle bodies 3, multiple degrees of freedom of the lifting vehicle body 3 are restricted, so that the lifting vehicle body 3 can only move up and down along the guide groove 2. The vehicle body 1 is driven by multiple wheels 6 to carry the goods and move.

[0027] Further as Figure 1 As shown, it is worth noting that the bottom of both reinforcing ribs 7 is equipped with hydraulic cylinders that drive the lifting vehicle body 3 to move up and down; in actual operation, the two hydraulic cylinders synchronously drive the two lifting vehicle bodies 3 to move up and down synchronously.

[0028] Further as Figure 1 , Figure 4 and Figure 5 As shown, it is worth noting that both ends of the guide groove 2 are set to be arc-shaped and the arc-shaped ends fit snugly with the roller bearing 4. In actual operation, the arc-shaped ends on the guide groove 2 effectively reduce the wear of the roller bearing 4 and the end of the guide groove 2, thus extending the service life of the components.

[0029] Further as Figure 2 As shown, it is worth noting that reinforcing ribs 7 are fixed on the inner wall of the lifting vehicle body 3, and multiple reinforcing ribs 7 are provided; during actual operation, the overall strength of the lifting vehicle body 3 is enhanced by the multiple reinforcing ribs 7.

[0030] In summary: By installing roller bearings 4 on the lifting vehicle body 3 and opening guide grooves 2 on the side of the vehicle body 1 where lifting is not required, the roller bearings 4 can be inserted into the guide grooves 2 for movement and lifting. Thus, the lifting movement of the lifting vehicle body 3 is guided by the cooperation of the guide grooves 2 and the roller bearings 4. By installing roller bearings 4 at different parts of the lifting vehicle body 3, multiple degrees of freedom of the lifting vehicle body 3 are restricted, so that the lifting vehicle body 3 can only move up and down along the guide grooves 2. The overall guiding structure is relatively simple, with low manufacturing and usage costs. At the same time, this guiding structure has low requirements for the machining precision of the vehicle body. The roller bearings 4 roll in the guide grooves 2 to guide the lifting vehicle body 3, making it less prone to jamming. Installation is convenient, and maintenance is simple and convenient. The arc-shaped end on the guide groove 2 effectively reduces the wear of the roller bearings 4 and the end of the guide groove 2, extending the service life of the components. The multiple reinforcing ribs 7 enhance the overall strength of the lifting vehicle body 3.
