The centering frame 16 is used for centering operation, and can ensure the position accuracy of the stacker head rail 18 and the upper cross beam 11. The principle of this embodiment is that the centering frames 16 are installed on the upper beam 11 in pairs corresponding to the two sides of the stacker sky rail 18, jackscrews penetrate through jackscrew holes 160 in the centering frames 16 on the two sides, the front ends of the jackscrews are abutted against the side surfaces of the stacker sky rail 18, and when the distance between the jackscrews on the two sides entering the outer side surfaces of the centering frames 16 is equal, the stacker sky rail 18 can be ensured in the center above the upper beam 11, and the parallelism between the stacker sky rail 18 and the upper beam 11 can be ensured. After the installation is completed, the jackscrew is removed, and at this time, the centering frame 16 plays a role in limiting and protecting. In this embodiment, there are 2 pairs of the centering frames 16, which are respectively disposed at two ends of the upper beam 11. In addition, in this embodiment, the centering frame 16 includes a first base plate 161, a riser 162 and a first rib plate 163, the first base plate 161 is connected to the upper cross member 11 through a connector, the riser 162 is disposed on the first base plate 161, the riser 162 is perpendicular to the first base plate 161, the jackscrew hole 160 is disposed on the riser 162, and two side edges of the first rib plate 163 are respectively fixed to the first base plate 161 and the riser 162.

In the field of lifting drive of a cargo carrying platform of a stacker, a steel wire rope is usually adopted to be matched with a pulley block to realize the lifting drive of the cargo carrying platform. According to the steel wire rope arrangement structure of the ultrahigh heavy load double-column stacker disclosed by the application number CN202122074412.8, the load requirement is met by adopting symmetrical fixed pulleys and movable pulley mechanisms and the number of steel wire rope strands is more than or equal to 8. However, in actual implementation, because the number of strands of the steel wire rope between the fixed pulleys on one side is greater than or equal to 4 strands, the number of annular grooves for winding the steel wire rope on the pulleys is at least 2, the steel wire rope 191 is wound in a way that the annular groove a1921 on the movable pulley a192 is wound in half a turn, then the steel wire rope extends downwards and is wound on the annular groove c1931 on the fixed pulley b193, and then the steel wire rope extends upwards and is wound on the other annular groove b1922 of the movable pulley a192 after being wound in half a turn, and the process is repeated. At this time, when the conventional shaft cores of the movable pulley a192 and the fixed pulley b193 are arranged in a parallel state, the rope strands of the steel wire rope 191 connecting the annular groove a1921 and the annular groove c1931 and connecting the annular groove c1931 and the annular groove b1922 incline, the rope strands interfere with the groove wall of the annular groove on the pulley, a bending angle is generated, and after long-term use, on one hand, the stability of lifting operation of the overload stacker is influenced, on the other hand, the steel wire rope is abraded, the service life is influenced, and potential safety hazards exist.

With reference to fig. 3, fig. 5, and fig. 6, in this embodiment, a pulley block 12 is disposed on the upper beam 11, the pulley block 12 includes a first fixed pulley 121 and a movable pulley 122, the movable pulley 122 is disposed below the first fixed pulley 121, a first annular groove 1211 is disposed on a side surface of the first fixed pulley 121, a second annular groove 1221 is disposed on a side surface of the movable pulley 122, and the stacker further includes a traction steel wire rope 13, where the traction steel wire rope 13 is wound around the first annular groove 1211 and the second annular groove 1221.

Based on the principle, as shown in fig. 6, the working principle of the stacker with the heavy load in this embodiment is that one end of the traction steel wire rope 13 is fixed on the driving roller 15, the other end of the traction steel wire rope is connected with the cargo carrying platform 3, and the traction steel wire rope 13 is pulled by the traction motor and the cargo carrying platform 3 is lifted by the pulley block 12. Here, projections of cross sections of both ends of each strand 131 at tangents to the first annular groove 1211 and the second annular groove 1221, that is, tangents where the traction wire rope 13 passes in or out of the first annular groove 1211 or the second annular groove 1221 correspond to each other on a horizontal plane, and in this embodiment, the "correspondence" means that the projections tend to coincide with each other when the strands 131 are in a nearly vertical state. Therefore, the interference between the traction steel wire rope 13 and the side wall of the annular groove on the pulley block 12 can be avoided, and a bending angle is generated, so that the stability of the lifting operation of the overload stacker can be improved, and the service life can be prolonged.

It should be noted that when the number of the first annular grooves 1211 and the second annular grooves 1221 is greater than 1, theoretically, by adjusting the preset included angle, the projections of the two ends of each strand 131, which correspond to the tangents of the first annular groove 1211 and the second annular groove 1221, on the horizontal plane cannot completely coincide, and therefore, the strands 131 cannot completely keep each in the vertical arrangement theoretically. However, in practical implementation, by adjusting the width of the annular groove on the pulley to be slightly wider than the diameter of the traction cable 13, it can be ensured that the cable does not interfere with the annular groove on the pulley, thereby eliminating the influence of the projection overlap ratio deviation on the horizontal plane of the cross section corresponding to the tangency between the two ends of the strand 131 and the first annular groove 1211 and the second annular groove 1221.

In this embodiment, the number of the first annular grooves 1211 and the number of the second annular grooves 1221 are each 2.

The second fixed pulley 14 functions as an upper guide pulley, and the traction steel wire rope 13 extends from the driving roller 15 to wind on the second fixed pulley 14 and then extends from the second fixed pulley 14 to wind on the pulley block 12. In this embodiment, the pulley block 12, the traction cable 13, the second fixed pulley 14 and the driving roller 15 are arranged in pairs at two ends of the pulley block 1. The number of the second fixed pulleys 14 on each side is 2.
