[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0027] Reference Figures 1 to 4 The multi-guide wheel stacker provided in this embodiment includes: two columns 1 and a cargo platform frame 3 located between the two columns 1, and the cargo platform frame 3 is connected to the columns 1 through a guide wheel group; the guide wheel group includes a column guide wheel group and a side guide wheel group.

[0028] The column guide wheel group includes two pairs of column guide wheels 4, one pair of column guide wheels 4 is located at the upper end of the frame, and the other pair of column guide wheels 4 is located at the lower end of the frame; each pair of column guide wheels 4 includes two column guide wheels 4, which are tightly clamped on the column 1 along the width direction and can roll on the column 1 in the up and down directions.

[0029] The column guide wheel 4 includes a tripod 7, which is arranged on the cargo platform frame 3 through a rotating shaft 8, and the tripod 7 is provided with two rollers, and the rotating shaft 8 and the two rollers are arranged in a triangle. The verticality of the surface of the column 1 is poor, and when the column guide wheel 4 passes through a convexity or a concaveness, the tripod 7 can rotate so that each roller is attached to the surface of the column 1.

[0030] The side guide wheel group includes two side guide wheels 5 adapted to the inner side of the column 1, wherein one side guide wheel 5 is located at the upper end of the cargo platform frame 3, and the other is located at the lower end of the cargo platform frame 3, and can slide in the up and down directions.

[0031] The guide wheel group is used to enable the cargo platform frame 3 to slide up and down along the column 1. The column guide wheel 4 limits the shaking in the width direction, and the side guide wheel 5 is used to limit the shaking in the length direction. Among them, each column guide wheel 4 has two rollers. The axial force of each roller is reduced by the multi-wheel structure, and the two rollers and the rotating shaft form a triangular structure, so that each roller can fit on the surface of the column 1 and bear the force evenly, thereby reducing the failure rate of the column guide wheel 4.

[0032] Specifically, an elevator guide rail 2 extending in the vertical direction is provided on the inner side of the column 1, and the side guide wheel 5 is adapted on the elevator guide rail 2. The elevator guide rail 2 has higher precision than the column 1, ensuring the stable operation of the stacker in the vertical direction and preventing the guide rail from being twisted due to excessive height.

[0033] The guide wheel group also includes a support wheel group; the support wheel group is located between the two side guide wheels 5, and includes two support guide wheels 6 arranged in the width direction, and the two support guide wheels 6 are adapted to the inner side of the column 1. The two support guide wheels 6 arranged in the width direction can prevent the stacker frame from twisting during the lifting process, thereby improving the stability of the operation.

[0034] Here, it should be noted that the functions, algorithms, methods, etc. involved in the present utility model are merely conventional adaptive applications of the prior art. Therefore, the improvement of the prior art by the present utility model is essentially the connection relationship between the hardware, rather than the functions, algorithms, and methods themselves.
