Drive in rack (also called drive through shelf), is composed of column frame, arm, pallet rail, top beams, middle beams, top bracing, and back bracings. This racking is suitable for single type products, whole storage mode warehouse. The forklift can enter the storage area, the warehouse has a high utilization rate. It is mostly used in low-temperature cold chain logistics, beverages, food, and milk. Products and other fields.
Drive-in racking system has typical FILO storage features. Forklift mainly operate on the “high-lift and high-drive” model. When the goods are lifted, the gravity of the goods is higher. Forklifts are prone to sway due to the unevenness of the ground on the channel, which can hit the rackings. It will affect the stability and safety of the racking structure. Therefore, the driver's driving skills are more demanding. It also affected the turnover speed and efficiency of the goods to some extent.
The structural design of the drive-in racking is the most critical factor in determining the racking quality. In addition, the racking material, production process, production equipment and electrostatic spraying will directly affect the quality of the racks. The main structure of drive in racking is Multiple statically indeterminate space steel structures. Using traditional classical mechanics methods or dynamic method to calculate its strength, stiffness and stability would be cumbersome. We propose to use a simplified calculation model and combine domestic and foreign standards, specifications and test data to analysis and optimize the design. At present, we most adopt the finite element structural strength analysis and stability analysis to auxiliary design and full-scale load test verification.
Drive-in rack is a portal structure. In order to ensure its stability, the slenderness ratio of the column should not be too high. Usually, it should be controlled within 10 meters, and it should be 4 levels and 3 to 5 lanes. Compared with the same type of pallet racking, except using bigger size steel section, drive in rack also need to add tensile structures. The main acessaries of the drive-in rack include upright frames, arm and pallet rail, top beams, top bracing, back bracing, upright guards (protective parts of the front of the shelf).
In the design process of the drive-in rack, the first thing we should do is to confirm the pallet size, pallet stacking height and pallet max loading capacity. Then design the overall structure of the drive-in rack and the key dimensions such as the span, depth, layer spacing, and height of the storage unit. When design the racking, we should conduct design verification or test verification on key parameters, establish a corresponding mechanical simplified model according to the case structure, based on the actual load (including seismic load, etc.) and load distribution of the shelf, combined with the geometric parameters and quality characteristics of the corresponding component sections, the design and check of strength, stiffness and stability are carried out. If necessary, it can be verified by experiments to ensure that the design results match the actual ones.
