Description

Technical Field

[0001] The utility model relates to a cargo stacking rack, in particular to a tire stacking rack used for storing tires mounted on wheel hubs in a warehouse. Background Art

[0002] In order to improve logistics support capabilities, ensure transportation efficiency, and reduce tire repair time, large logistics companies or transport fleets need to install tires on wheel hubs and inflate them for long-term storage as spare tires. Because the rubber layer on the tire sidewalls is relatively thin, long-term flat placement will cause the tire sidewalls to deform. Therefore, tires cannot be directly stacked on top of each other. CN214649996 U discloses a tire storage device for warehouses, including a base, a groove is formed in the middle of the base, and two sets of support shafts are rotatably mounted in the groove. Two sets of side plates are fixedly mounted on both sides of the surface of one side of the base, and are symmetrically distributed and perpendicular to the base. A screw parallel to the support shaft is rotatably mounted on the middle of the side plate away from the base. A first movable plate is rotatably mounted on the screw, which is parallel to the base. Two sets of clamping rods are fixedly mounted on the first movable plate near the outer side of the base surface. The warehouse uses tire storage equipment to ensure orderly storage and secure tires, preventing them from shaking due to external factors during storage. This ensures storage stability and allows tires to rotate in place, preventing them from detaching from their bases. This allows for changes in tire status and facilitates subsequent inspections. While vertical tire storage can prevent sidewall compression and deformation, prolonged pressure on a single point while stationary can also cause deformation, damage, or even render the tire useless. To address this problem, CN 118270430 A discloses an automatic flipping high-level tire storage rack. The rack comprises at least one shelf and at least one tray assembly. Multiple horizontally arranged shelves form the load-bearing surface of the tray assembly. Each shelf has a drive shaft disposed along its length at its lower end. Several driving gears are fixedly connected to the drive shaft. The shelves are cut with slots that match the driving gears, and the upper ends of the driving gears extend through the slots to above the shelf end surfaces. The multiple drive shafts are interconnected, and one of the multiple drive shafts is connected to a power unit. The tray assembly includes a bracket with several rotating shafts movably disposed along its length. One of the rotating shafts is provided with a driven gear that matches the driving gear. This invention enables high-density, three-dimensional storage of tires without external pressure and automatic tire flipping. However, this automatic flipping high-level tire storage rack is complex in structure, requires electricity to maintain tire rotation, has high operating and maintenance costs, and requires specialized equipment for tire retrieval. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to provide a tire stacking rack for a warehouse. When the tire stacking rack is used to store tires, the tire rubber will not be subjected to pressure and load, which can avoid a certain point of the tire being compressed for a long time, causing the tire to be deformed, damaged or scrapped. The tire stacking rack for a warehouse has the advantages of simple structure, easy tire removal and placement, and low operation and maintenance costs.

[0004] The technical solution adopted to solve the technical problem is as follows: A tire stacking rack for a warehouse includes a tire stacking cage that can be stacked and stacked. The tire stacking cage includes a tire stacking cage composed of four columns, four lower cross beams, and four upper cross beams. The projection of the tire stacking cage on a horizontal plane is a square. A spare tire lifter that can hang tires in the tire stacking cage is provided on the upper part of the tire stacking cage. The spare tire lifter is located at the center of the square projected by the tire stacking cage. The spare tire lifter is fixed to the upper part of the tire stacking cage by two parallel load-bearing beams. The two ends of the two load-bearing beams are respectively connected to the two parallel upper cross beams.

[0005] As a further improvement of the present invention: the column is a hollow column made of a square tube, and a positioning plug is fixed at the upper end of the hollow column. The positioning plug is composed of a positioning column that is inserted into the inner hole of the square tube and a guide head arranged at the upper end of the positioning column. The guide head is a quadrangular pyramid with the upper end face of the positioning column as the bottom face, and each corner of the quadrangular pyramid has a circular chamfer.

[0006] As a further improvement of the present invention, the angle between the inclined surface and the bottom surface of the quadrangular pyramid is 60-70 degrees.

[0007] As a further improvement of the present invention, a fork installation gap is left between the bottom surface of the lower cross beam and the lower end surface of the column for the fork to enter.

[0008] As a further improvement of the present invention, a supporting column is provided between the upper crossbeam and the lower crossbeam at both ends of the load-bearing beam, and the supporting column is located in the middle of the two load-bearing beams.

[0009] As a further improvement of the present invention: the spare tire lifter is a hand-crank spare tire lifter.

[0010] Beneficial effects: The tire stacking rack for warehouses of the utility model adopts a technical solution that the tire stacking rack for warehouses includes a tire stacking cage that can be stacked, and a spare tire lifter that can hang the tire in the tire stacking cage is provided on the upper part of the tire stacking cage. When storing tires, the spare tire lifter is used to hang the tire in the tire stacking cage, so that the tire rubber does not contact any other objects except the rim of the wheel hub. While ensuring the ventilation effect, the tire rubber is avoided to the greatest extent from being compressed and deformed or damaged by air leakage at a single point for a long time. Since a one-tire-one-cage storage method is adopted, the management and access of tires are more convenient. No electric rotation is required during the storage of tires, and the equipment is easy to operate and maintain. The tire stacking rack for warehouses has a simple structure and low manufacturing cost. Because the columns are hollow, square tube-shaped, and fixed at their upper ends, positioning plugs are constructed from a positioning post that fits into the inner hole of the square tube and a guide head mounted at the upper end of the post. The guide head is a rectangular pyramid with the upper end of the positioning post as its base, and each corner of the pyramid features rounded chamfers. During stacking, the positioning plugs of the tire stacking rack for the lower warehouse are inserted through the lower ends of the columns of the tire stacking rack for the upper warehouse, aligning the four columns of the upper and lower warehouse tire stacking racks and forming a neat stacking structure. This facilitates stacking operations and reduces the weight of the tire stacking racks themselves. The angle between the inclined surface and the base of the rectangular pyramid is 60-70 degrees, ensuring the positioning plug's automatic alignment and guidance while also enhancing its strength and impact resistance. Due to the technical feature of a fork-mounting gap between the bottom surface of the lower crossbeam and the lower end surface of the column to allow fork access, forklifts can be easily used during the stacking process, making it easier for forks to move in and out without contacting the tires. Due to the technical feature of providing support columns between the upper and lower crossbeams at both ends of the load-bearing beams, with the support columns located between the two load-bearing beams, the warehouse tire stacking rack of this utility model has a stronger load-bearing capacity and can meet the storage needs of large trucks and off-road vehicle tires. Due to the technical feature of a hand-cranked spare tire lifter, the warehouse tire stacking rack of this utility model is simpler to operate, more adaptable to the environment, and more reliable while reducing manufacturing costs.
