Description

Technical Field

[0001] The utility model relates to the technical field of automated warehousing and logistics, in particular to a reversing track for four-way vehicles. Background Art

[0002] Currently, the design and implementation of four-way shuttle-type dense storage systems typically employs a composite structure for the reversing rails used to transition from a sub-aisle to the main aisle, or vice versa. The upper layer comprises the reversing rails, while the lower layer comprises the joists, both of which rely primarily on rectangular tubes as their basic components. This design often requires pre-welding in the factory or on-site assembly and connection using bolts. While this structural solution achieves functional requirements to a certain extent, it also has significant drawbacks. Specifically, the core issue with this structure is that rectangular tubes, as standard profiles, have a relatively wide tolerance range. When multiple rectangular tubes are stacked, the cumulative error significantly increases, posing a challenge to the precise operation of the system. From a production perspective, this structure requires extensive welding, which not only complicates the production process but also easily causes deformation during welding, making it difficult for the final product to precisely meet the dimensional requirements of the design drawings. Furthermore, this solution consists of multiple discrete components, which not only increases the workload during on-site installation but also makes dimensional accuracy control particularly difficult due to the high inter-component coordination requirements. What is more serious is that this structural design is not efficient in material utilization, resulting in a lot of material waste, which in turn pushes up the overall cost.

[0003] In summary, the currently adopted technical solutions have the following obvious deficiencies: The process is complex and cumbersome: Due to the large number of parts involved, the production process becomes lengthy, which not only increases the difficulty of management but also prolongs the production cycle of the product. Difficulty in controlling dimensional accuracy: All parts are connected by welding processes, and welding itself is easily affected by various factors, resulting in difficulty in stably controlling dimensional accuracy, affecting the overall performance of the system. Frequent welding quality problems: Cold welding is not easy to detect in time, and desoldering is prone to occur under long-term use, which seriously shortens the service life of the system. Difficulty in ensuring horizontality after installation: After installation, the horizontal state of the welded structure is difficult to accurately adjust, which not only affects the stability of the shelf, but also increases the difficulty and cost of subsequent engineering debugging. Therefore, in response to the above problems, exploring a more advanced, efficient and cost-effective reversing rail structure design scheme is of great significance to improving the overall performance and market competitiveness of the four-way shuttle dense storage system.

[0004] In view of the problems existing in the prior art, it is of great significance to provide a reversing track for four-way vehicles. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a four-way vehicle reversing track.

[0006] To achieve the above-mentioned purpose, the four-way vehicle reversing track of the present invention comprises a reversing rail body and a connecting member, wherein both ends of the reversing rail body are provided with positioning grooves matching the connecting member; the connecting member is detachably fixedly connected to the reversing rail body through the positioning grooves, and the connecting member is an integrated U-shaped bending structure;

[0007] Furthermore, the connecting member includes a front end of a body and a rear end of a body, the front end of the body is an integrated U-shaped bent structure, the front end of the body includes a bottom wall and two front side walls that are perpendicularly bent relative to the bottom wall, and also includes two front top walls formed by folding the two front side walls outward; the rear end of the body includes the bottom wall and two rear side walls that are perpendicularly bent relative to the bottom wall;

[0008] Furthermore, it further comprises an end plate, wherein the end plate is fixedly connected to the tail end side wall of the connecting member;

[0009] Furthermore, both ends of the reversing rail body are specifically provided with positioning grooves matching the front end of the body of the connecting member;

[0010] Furthermore, it also includes a main rail, and a first mounting hole is provided on the front end top wall, and the main rail is installed in the positioning groove through the mounting hole;

[0011] Furthermore, a second mounting hole is provided on each of the side walls of the tail end; the connecting member is detachably fixedly connected to the reversing rail body through the second mounting hole;

[0012] Furthermore, a third mounting hole is provided on the front side wall; the connecting member is detachably fixedly connected to the reversing rail body through the third mounting hole;

[0013] Furthermore, a fourth mounting hole is provided on the bottom wall; the connecting member is detachably fixedly connected to the reversing rail body through the fourth mounting hole;

[0014] Furthermore, the reversing rail body is an integrated structure, and the positioning groove is specifically opened by laser cutting.

[0015] The utility model provides a four-way vehicle reversing track. By providing an integrated U-shaped bending structure connector and an integrated reversing track body, it brings many significant advantages: it can simplify the assembly process and improve structural integration. The integrated design greatly reduces the number of parts to be assembled, especially for key reference surface parts, achieving structural integration. It not only simplifies the production process, but also enhances the stability and reliability of the overall structure, making the reversing track perform better in complex working environments. Optimize the manufacturing process and improve precision and efficiency: In traditional track manufacturing, the widespread use of welding processes often becomes a key factor affecting the precision and strength of workpieces. However, by reducing the reliance on welding processes, the utility model not only effectively avoids the dimensional deviations that may occur during the welding process, but also significantly improves the overall precision of the workpiece, ensuring the high-precision operation of the reversing track. Strengthen the main load-bearing parts and eliminate the risk of desoldering: The main load-bearing parts adopt an integrated design, which fundamentally eliminates the desoldering phenomenon caused by loose welding, greatly enhances the load-bearing capacity and safety of the track, and extends its service life. Reduce the number of welded components and reduce cumulative errors: The reduction in the number of welded components directly reduces the range of cumulative errors, significantly reducing the probability of rework during the production and installation of the track, and improving production efficiency and finished product quality. Enhance structural strength and reduce installation deformation: The overall strength of the reversing track after the structural change has been significantly improved, effectively reducing the probability of deformation due to external forces during the installation process, ensuring the precise alignment and stable operation of the track. Simplify the debugging process and reduce work intensity: The reduction in deformation means that the intensity of horizontal debugging work is also reduced after the shelf is assembled. This not only saves labor costs, but also speeds up the overall installation progress and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
