Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to a sub-track for a four-way pallet truck. Background Art

[0002] The four-way vehicle pallet vertical storage rack is a cargo storage device assembled by steel structures, which is widely used in storage warehouses. Its storage and retrieval methods can be first-in, first-out or first-in, last-out, and the storage and retrieval methods are relatively flexible.

See Figure 1 As shown, the sub-track in the prior art is a thin-walled sheet metal part. This sub-track structure has poor load-bearing performance. When encountering a large load or a large distance between the support points of a large-size pallet, the bending deformation is large, the walking resistance of the trolley is large, and the transition between the sub-track and the reversing track is not smooth, which will have an adverse impact on the smoothness and service life of the trolley.

A first bending part is provided at one end of the side plate away from the first main board. One of the first bending parts is located inside one end of the second profile, and the other first bending part overlaps on the outside of the other side of the second profile.

[0007] Preferably, the second profile includes a second main board. The second main board is arranged in an L shape, and both ends of the second main board have second bending parts.

[0008] As a further preference, one of the first bending parts is located inside one of the second bending parts, and the other first bending part overlaps on the outside of the other second bending part.

[0021] Figure 2 It is a schematic structural view of the sub-track of the four-item pallet truck in the present utility model; Figure 3 It is a usage state diagram of the sub-track of the four-item pallet truck in the present utility model. Please refer to Figures 2 to 3 As shown, it shows a preferred embodiment, showing a sub-track 5 for a four-item pallet truck, including a first profile 1 and a second profile 2. The first profile 1 includes a first main board 101 and side plates 102. The first main board 101 is arranged in an L shape, and two side plates 102 are provided at both ends of the first main board 101. The two side plates 102 are integrally connected to the first main board 101. One end of the side plate 102 away from the first main board 101 is provided with a first bending portion 103. One of the first bending portions 103 is located inside one end of the second profile 2, and the other first bending portion 103 overlaps on the outer side of the other side of the second profile 2. In this embodiment, please refer to Figure 2 As shown, the first profile 1 and the second profile 2 are welded together to form an integral structure. And through the design of the structures of the first profile 1 and the second profile 2, the load-bearing performance of the sub-track 5 is improved, and at the same time, the amount of torsional deformation generated after being stressed is reduced, which can improve the walking stability of the trolley 3.
