[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0034] Example

[0035] See attached Figure 1-3 As shown, a single-column stacker of the utility model comprises a column 1, a cargo platform 2, a lifting mechanism 3, and a guide mechanism, wherein the cargo platform 2 comprises a cargo platform body 21, and a support 22 capable of holding on the column 1 is provided on the side of the cargo platform body 21 facing the column 1. The lifting mechanism 3 is mounted on the column 1 and can drive the cargo platform 2 to move up and down along the column 1. The guide mechanism comprises a first guide part 4 and a second guide part 5 used in conjunction. The first guide part 4 comprises straight rails 41 symmetrically arranged on both sides of the column 1, the straight rails 41 are arranged in the vertical direction, at least one slider 42 is slidably arranged on the straight rails 41, and all the sliders 42 are mounted on the support 22; the second guide part 5 comprises a first fixed pulley 51, a second fixed pulley, and a steel wire rope 52 arranged in a closed loop around the first fixed pulley 51 and the second fixed pulley, the first fixed pulley 51 and the second fixed pulley are arranged at the upper and lower ends of the column 1 respectively in the vertical direction, and the steel wire rope 52 is connected to the support 22.

[0036] When the cargo platform 2 moves up and down along the column 1 driven by the lifting mechanism 3, the slider 42 can move up and down along the corresponding straight rail 41, and at the same time, the wire rope 52 is driven to drive the first fixed pulley 51 and the second fixed pulley to roll. At this time, the support 22 can maintain stable movement under the dual guidance of the straight rail 41, the slider 42 and the wire rope 52.

[0037] There are two types of guide parts in the guide mechanism. The first type is to realize the movement guidance of the support 22 through the cooperation of the straight rail 41 and the slider 42, so as to improve the guiding accuracy of the movement of the support 22 (and the cargo platform 2); the second type is to realize the movement guidance of the support 22 through the cooperation of the wire rope 52 and the first fixed pulley 51 and the second fixed pulley. While guiding the movement of the support 22, the supporting strength of the support 22 (and the cargo platform 2) is guaranteed, thereby enhancing the stability of the movement of the support 22 (and the cargo platform 2).

[0038] In some embodiments, see Appendix Figure 2As shown, each straight rail 41 is provided with two sliders 42 arranged up and down, and the two sliders 42 are respectively located at the upper and lower ends of the support 22 to improve the guiding stability of the movement of the support 22 as much as possible.

[0039] In order to define the limit position of the movement of the support 22, in some embodiments, see the attached Figure 3-5 As shown, the upper and lower ends of the straight rail 41 are respectively provided with stop plates 43, which are fixed to the column 1, and the side of the stop plate 43 facing the support 22 is provided with a buffer column 44 for the support 22 to abut. For example, the buffer column 44 can be a cylindrical spring. First, the setting of the stop plate 43 can limit the up and down movement range of the support 22 and the cargo platform 2, and then the setting of the buffer column 44 can play a role in buffering and reducing the speed of the moving support 22, so as to reduce the rigid impact damage to the support 22.

[0040] Furthermore, the straight rail 41 includes a rail body, and arc grooves are symmetrically arranged on both sides of the rail body; the slider 42 is held on the rail body, and a profiling block is arranged on it corresponding to the arc groove; the profiling block is located in the corresponding arc groove. The coordination of the arc groove and the profiling block ensures the stability of the slider 42 moving on the straight rail 41, and effectively prevents the slider 42 from derailing.

[0041] In some embodiments, the support 22 includes a support main board and support side panels located on both sides of the support main board, and the support side panels and the support main board together form a "U"-shaped structure. A spacing is left between the support main board and the column to reduce the friction resistance between the support 22 and the column 1 during the movement. The support side panels are arranged in a one-to-one correspondence with the straight rails 41, and at least one slider 42 that can slide along the corresponding straight rail 41 is provided on the side facing the straight rail 41. The support 22 can be held on the column 1 through the cooperation of the support main board and the support side panels to improve the stability and safety of the support 22 moving on the column 1.

[0042] The upper ends of the support main plate and the support side plates are provided with a support top plate 221, and a connection plate connected to the steel wire rope 52 is provided on the support top plate 221. Specifically, a hinge plate 222 is fixedly connected to the connection plate near the steel wire rope, and the upper and lower ends of the hinge plate 222 are respectively pivotally connected to connection seats 223, and the two free ends of the steel wire rope 52 are respectively fixed to the two connection seats 223. The pivot connection between the connection seat 223 and the hinge plate 222 can provide a certain margin for the possible shaking of the steel wire rope 52, so as to further enhance the reliability of the connection between the connection plate and the steel wire rope 52.

[0043] In some embodiments, a horizontal walking mechanism 6 is provided on the cargo platform body 21 to achieve horizontal transfer of cargo. A reinforcing rib 23 is connected between the support 22 and the cargo platform body 21 to improve the connection strength between the support 22 and the cargo platform body 21. It should be noted that the horizontal walking mechanism 6 is a prior art and will not be described in detail in this embodiment.

[0044] In some embodiments, see Appendix Figure 1 As shown, the lifting mechanism 3 includes a lifting drive (such as a motor), a winding drum, a traction rope, a lifting fixed pulley, and a lifting movable pulley. The winding drum is arranged on the lower end of the column 1 and can rotate under the action of the lifting drive. The lifting fixed pulley is located at the upper end of the column 1, and the lifting movable pulley is located on the support 22. One end of the traction rope passes around the lifting movable pulley and is fixed to the column 1, and the other end passes around the lifting fixed pulley and is wound around the winding drum. The lifting and lowering movement of the support 22 is achieved by winding or unwinding the traction rope on the winding drum.

[0045] Furthermore, at least one maintenance platform 11 is arranged along the vertical direction of the column 1, and a maintenance ladder 12 corresponding to the maintenance platform 11 is arranged on one side of the column 1, so as to facilitate maintenance of the stacker at different heights.
