Description

Pallet rack containing a load beam with a load reinforcement function {A pallet rack containing a load beam with a load reinforcement function}

The present invention relates to a pallet rack including a load beam with a load reinforcement function, and more specifically, to a pallet rack for seating and storing goods in a logistics warehouse (or logistics warehouse), etc. This relates to a pallet rack that includes a load beam connecting the vertical pillars and has a load reinforcement function that can withstand high loads and maximize support without deformation.

In general, a logistics warehouse (or logistics warehouse) is a storage warehouse for temporary or long-term storage of all items used in daily life, such as various foods, beverages, clothing, home appliances, miscellaneous goods, and industrial supplies produced in large quantities at a factory or production site. It is used as.

In addition, due to the recent rapid development of the logistics industry, these warehouses are moving beyond simple logistics management and are seeking to create new businesses such as product placement of stored inventory in the warehouse, efficient warehousing, shipping, and inventory management, and mass-produced warehouses. It is designed and constructed to store large quantities of logistics through more efficient use of logistics loading space, along with faster receipt and shipment of goods.

The design and operation of the above-described logistics warehouse is generally to divide racks with a width and height that can accommodate pallets of a certain size into each passage section and install them vertically in multiple stages, and then to the passage of the fixed reference rack. Pallets loaded with logistics are stored in the pallet rack (Pallet-Rack) through a forklift or forklift in the section.

In addition, when it is desired to ship loaded logistics, the pallet with loaded logistics is similarly moved to the ground or a transport vehicle using a forklift or forklift.

As shown in Figures 1 and 2, the warehouse includes a rack section where the pallet rack 100 is installed, and a main passage and a variable passage for the movement of forklifts, and the pallet rack 100 is a pallet (P) of a certain size. It is composed of a plurality of load beams 200 and vertical columns 300 having a certain width and height combined with each other so that the load can be deposited and withdrawn. That is, between a vertical pillar 300 installed in a vertical direction with respect to the floor surface and a load beam 200 fixed in the horizontal direction at a certain height interval between the vertical pillars 300 and the load beam 200. In order to maintain the gap between the tie beams 400 and the vertical columns 300, which are installed at right angles in the horizontal direction at regular intervals, horizontal bracing 500 and diagonal bracing 600 are coupled to the rear of each vertical column 300. ), including.

Therefore, by placing the pallet P loaded with boxes of goods, etc. on the tie beam 400 seated on the load beam 200, a narrow space can be efficiently used to store or load more goods. And, by only taking out the pallet (P) when necessary, storage is very convenient and logistics management is improved.

Meanwhile, when loading or transporting goods on the pallet rack 100, the rear of the forklift collides with the vertical pillar 300 of the pallet rack 100 while the goods are being transported by a forklift loaded with the goods, causing the vertical Partial damage to the pillar 300 frequently occurred. At this time, the load of the goods stored in the pallet rack 100 is concentrated not only on the damaged vertical column 300 but also on the load beam 200, which may eventually lead to the entire pallet rack 100 being tilted and damaged. To prevent this, In most cases, the partially damaged vertical column 300 and load beam 200 are replaced with new ones.

However, when manufacturing a conventional pallet rack, not only is the production cost high due to the large number of components for the pallet rack, but also the assembly efficiency is reduced due to the complexity of assembly when installing the pallet rack.

That is, when installing a pallet rack, a vertical pillar 300 is erected and a load beam is connected between the vertical pillars 300 and the vertical pillar 300 by a bracket. In this case, the vertical pillar 300 and When connecting brackets, the joint part moves left and right, is weak under high loads and is deformed, and the support bonding force is weak, which poses a risk for long-term storage of goods.

In addition, when assembling the vertical column 300 and the bracket, there is a problem of poor assembling, such as the worker having to hit the joint area using a hammer or the like.

As shown above, the joint between the vertical column 300 and the bracket is weak and easily damaged, so when replacing it with a new post bar, various parts for the pallet rack must be provided, and assembling is poor, installation costs increase, and maintenance costs for the loaded rack are increased. There was a problem that the efficiency of the warehouse operation was reduced due to the aggravation.

Also, when items are stored for a long period of time, the load beam 200 is the part where high load is applied the most and is also a vulnerable part.

Therefore, there was a problem of bending when a concentrated load was applied due to long-term storage of goods.
