High-rise storage facilities are also gradually common in industries such as molds, steel, and wood. However, in these industries, the handling and storage of large-size materials and heavy loads are special challenges for stackers. The weight of goods generally varies from several tons to tens of tons, and the size of goods varies from a few meters to more than ten meters. The super heavy load stacker involved in the present application is designed for this purpose. The overhead rail of the stacker is the rail for the lateral movement of the moving assembly of the stacker. The upper cross beam of the stacker is slidingly connected with the overhead rail of the stacker. In order to ensure the stability of the movement of the stacker, the position accuracy of the upper cross beam relative to the overhead rail of the stacker needs to be ensured when the stacker is assembled.

DETAILED DESCRIPTION

[0040] Example 1

[0041] In combination Figure 1 , Figure 3 and Figure 4 shown, an ultra-heavy load stacking machine includes an upper beam part 1, a column 2, a cargo platform 3, and a lower crossbeam part 4. The columns 2 are arranged in pairs at both ends of the lower crossbeam part 4. The upper beam part 1 is arranged on the pair of columns 2. The cargo platform 3 is arranged between the pair of columns 2 and is in sliding connection with the pair of columns 2. The upper beam part 1 includes an upper crossbeam 11, a stacking machine overhead rail 18, and a roadway track 49. The stacking machine overhead rail 18 is arranged above the upper crossbeam 11. The lower crossbeam part 4 is arranged on the roadway track 49. The upper crossbeam 11 is provided with a centering frame 16 at the top end. The centering frames 16 are arranged in pairs on both sides of the stacking machine overhead rail 18. There are at least two pairs of centering frames 16. The centering frames 16 are provided with jackscrew holes 160.

[0042] The centering frame 16 is used for centering operation, which can ensure the position accuracy of the stacker rail 18 and the upper cross beam 11. The principle of the embodiment is that the centering frame 16 is installed on the upper cross beam 11 corresponding to both sides of the stacker rail 18, and the top wire is arranged in the top wire hole 160 on the two sides of the centering frame 16. The front end of the top wire is in contact with the side surface of the stacker rail 18, until the distance between the two sides of the top wire entering the outer side surface of the centering frame 16 is equal, at this time, it can be ensured that the stacker rail 18 is in the center above the upper cross beam 11, and the parallelism of the stacker rail 18 and the upper cross beam 11 can be ensured. After installation, the top wire is removed, at this time, the centering frame 16 plays a role in limiting protection. In the embodiment, the centering frame 16 is provided with two pairs, which are respectively arranged at both ends of the upper cross beam 11. In addition, in the embodiment, the centering frame 16 includes a first bottom plate 161, a vertical plate 162 and a first rib plate 163, the first bottom plate 161 is connected with the upper cross beam 11 through a connecting piece, the vertical plate 162 is arranged on the first bottom plate 161, the vertical plate 162 is perpendicular to the first bottom plate 161, the top wire hole 160 is arranged on the vertical plate 162, and the two side edges of the first rib plate 163 are respectively fixed with the first bottom plate 161 and the vertical plate 162.

[0043] In combination with Figure 4 As shown in the figure, in the embodiment, the upper cross beam 11 is provided with an upper guide wheel part 17, the upper guide wheel part 17 is arranged on both sides of the stacker rail 18 in pairs, the upper guide wheel part 17 is provided with at least two pairs, the upper guide wheel part 17 includes an upper guide wheel 171 and an upper guide wheel table 172, the upper guide wheel 171 is rotatably arranged on the upper guide wheel table 172, and the upper guide wheel table 172 is connected to the upper cross beam 11 through a connecting piece. In the embodiment, the upper guide wheel part 17 is provided with two pairs, which are respectively arranged at both ends of the upper cross beam 11.

[0044] Further, the upper guide wheel platform 172 is provided with a limiting top plate 1721 on both sides, the upper cross beam 11 is fixed with a gap adjusting seat 173, the gap adjusting seat 173 corresponds to the limiting top plate 1721 one by one, the gap adjusting seat 173 is arranged outside the limiting top plate 1721, and the gap adjusting seat 173 is provided with an adjusting top screw 1731. The upper guide wheel 171 is arranged on the upper guide wheel platform 172, and when the upper guide wheel platform 172 is installed, a certain gap is required to be left between the side surface of the upper guide wheel 171 and the side surface of the stacker overhead rail 18. If the gap is too small, the installation error of the stacker or the straightness error of the stacker overhead rail 18 will cause interference between the stacker overhead rail 18 and the upper guide wheel 171, affecting the stability of the movement of the stacker. If the gap is too large, the upper cross beam will be insufficiently limited, causing the stacker to shake when moving. The connecting hole corresponding to the upper cross beam 11 of the upper guide wheel platform 172 is a long hole, leaving a certain movement space. The method for adjusting the gap is that the screw connecting the upper guide wheel platform 172 and the upper cross beam 11 is in a loosened state, a preset thickness of a plug gauge is inserted between the side surface of the stacker overhead rail 18 and the upper guide wheel 171, the adjusting top screw 1731 is screwed to make the front end of the limiting top plate 1721 move, until the side surface of the stacker overhead rail 18 and the upper guide wheel 171 are in close contact with the plug gauge, at this time, the screw connecting the upper guide wheel platform 172 and the upper cross beam 11 is tightened, and after the plug gauge is removed, the gap between the stacker overhead rail 18 and the upper guide wheel 171 can be ensured. Thus, the stability of the upper cross beam moving along the stacker overhead rail 18 is ensured. The gap adjusting seat 173 and the adjusting top screw 1731 also play a limiting role on the upper guide wheel platform 172 during the operation of the stacker.

[0045] In the field of lifting drive of the loading platform of the stacker, a steel wire rope is usually used in combination with a pulley block to realize the lifting drive of the loading platform. For example, a steel wire rope arrangement structure of an ultrahigh heavy-load double-column stacker disclosed in application No. CN202122074412.8 realizes the lifting drive of the loading platform by adopting a symmetrical fixed pulley and movable pulley mechanism and the number of steel wire strands is greater than or equal to 8, thereby meeting the load requirement. However, in the actual implementation process, the number of steel wire strands between the fixed pulleys on one side is greater than or equal to 4, so the number of annular grooves for winding the steel wire rope on the pulley is at least 2, and the method for winding the steel wire rope is as follows Figure 2As shown, the steel wire rope 191 is wound around the annular groove a1921 on the movable pulley a192 for half a turn, then extends downward to be wound around the annular groove c1931 on the fixed pulley b193, and then extends upward to be wound around the other annular groove b1922 on the movable pulley a192 for half a turn, and so on. At this time, when the conventional movable pulley a192 and the fixed pulley b193 are arranged in a parallel state, the strands of the steel wire rope 191 connecting the annular groove a1921 and the annular groove c1931 and the annular groove c1931 and the annular groove b1922 will be inclined and will interfere with the groove wall of the pulley, resulting in a bending angle. Long-term use will affect the stability of the super-heavy load stacking machine in lifting operation, on the one hand, and will cause the steel wire rope to wear and tear, affecting the service life, and there is a safety hazard.

[0046] In combination with Figure 3 , Figure 5 and Figure 6 , a super-heavy load stacking machine is provided. In the embodiment, the upper cross beam 11 is provided with a pulley set 12, the pulley set 12 includes a first fixed pulley 121 and a movable pulley 122, the movable pulley 122 is arranged below the first fixed pulley 121, the first fixed pulley 121 is provided with a first annular groove 1211 on the side surface, the movable pulley 122 is provided with a second annular groove 1221 on the side surface, and a traction steel wire rope 13 is wound around the first annular groove 1211 and the second annular groove 1221. A fixed pulley frame 123 is further included, the fixed pulley frame 123 is fixed on the upper cross beam 11, the first fixed pulley 121 is rotatably connected to the fixed pulley frame 123, the movable pulley 122 is fixed on the cargo platform 3, the rotation axis core of the first fixed pulley 121 and the rotation axis core of the movable pulley 122 form a preset included angle in the horizontal plane projection, the preset included angle is greater than 0°, and the traction steel wire rope 13 is wound between the first annular groove 1211 and the second annular groove 1221 to form a group of strands 131; through the arrangement of the preset included angle, the cross sections corresponding to the tangent positions of the first annular groove 1211 and the second annular groove 1221 at both ends of each strand 131 correspond to each other in the horizontal plane projection.

[0047] Based on the above principle, in combination with Figure 6As shown, the working principle of the super-heavy load stacking machine is that one end of the traction steel wire rope 13 is fixed on the driving drum 15, and the other end is connected with the loading platform 3. The traction motor drives the traction steel wire rope 13 to realize the lifting operation of the loading platform 3 through the pulley block 12. Among them, the projection of the cross section of each strand 131 at the tangent position of the first annular groove 1211 and the second annular groove 1221, that is, the tangent position of the traction steel wire rope 13 entering or exiting the first annular groove 1211 or the second annular groove 1221, corresponds to each other. In this embodiment, the so-called "correspondence" here means that the projections tend to coincide with each other, and at this time the strand 131 is close to the vertical state. Therefore, it can avoid the interference between the traction steel wire rope 13 and the side wall of the annular groove on the pulley block 12, and generate a bending angle, so as to improve the stability of the super-heavy load stacking machine lifting operation and improve the practical life.

[0048] It should be noted that when the number of the first annular groove 1211 and the second annular groove 1221 is greater than 1, in theory, by adjusting the preset included angle, the projection of the cross section corresponding to the tangent position of each strand 131 at the first annular groove 1211 and the second annular groove 1221 on the horizontal plane cannot completely coincide, therefore, in theory, the strand 131 cannot completely realize the vertical arrangement of each strand. But in the actual implementation process, by adjusting the width of the annular groove on the pulley, it is slightly wider than the diameter of the traction steel wire rope 13, which can ensure that the steel wire rope does not interfere with the annular groove on the pulley, thereby eliminating the influence of the deviation of the coincidence degree of the projection of the cross section corresponding to the tangent position of the strand 131 at the first annular groove 1211 and the second annular groove 1221 on the horizontal plane.

[0049] In this embodiment, the number of the first annular groove 1211 and the second annular groove 1221 is 2.

[0050] In addition, the rotation axis core of the movable pulley 122 is parallel to the extension direction of the upper cross beam 11, and the included angle between the rotation axis core of the first fixed pulley 121 on the fixed pulley bracket 123 and the extension direction of the upper cross beam 11 is in the range of 4° to 15°. The included angle is the preset included angle. In this embodiment, the preset included angle is 7°.

[0051] In this embodiment, a second fixed pulley 14 is also included, which is rotatably arranged on the upper cross beam 11, and the second fixed pulley 14 is arranged outside the first fixed pulley 121. The second fixed pulley 14 functions as an upper guide pulley, and the traction steel wire rope 13 extends from the driving drum 15, is arranged on the second fixed pulley 14, and then extends from the second fixed pulley 14 to the pulley block 12. In this embodiment, the pulley block 12, the traction steel wire rope 13, the second fixed pulley 14, and the driving drum 15 are arranged in pairs at both ends of the upper cross beam 11. The number of the second fixed pulleys 14 on each side is two.

[0052] Embodiment 2

[0053] A Chinese patent with the application number 201720588175.8 discloses a highly stackable double-column stacking column mechanism. According to the drawings in the specification, a connecting structure is arranged on the outer side of the column at the end of the column assembly, and a connecting piece is used to realize the splicing of the upper and lower column assemblies. For example, a Chinese patent with the application number CN201820245235.0 discloses a splicing type column stacking machine, which also adopts a similar outer connection form to realize the connection of the upper and lower columns. Since a linear guide rail needs to be installed on the column, the splicing type column with outer connection must reserve space for the installation of the guide rail and the movement of the guide wheel assembly of the guide rail. Therefore, the splicing structure with outer connection can only adopt a semi-enclosed connection and cannot realize uniform connection in the circumferential direction of the column connection. In the field of super heavy load type stacking machines, the semi-enclosed connection method has poor structural stability and cannot meet the load requirements of super heavy load type stacking machines.

[0054] In combination Figures 7 to 11 As shown in the drawings, in this embodiment, the column 2 is longitudinally spliced by a group of column bodies 21, the column body 21 has a hollow rectangular cross section, the end of the column body 21 is fixed with a rib plate 22, further includes a connecting frame 23, the connecting frame 23 is fixed on the outer side of the rib plate 22, the shape of the connecting frame 23 is adapted to the cross-sectional shape of the column body 21, further includes a group of mounting holes 231, the mounting holes 231 are integrally arranged on the connecting frame 23 and the rib plate 22, the mounting holes 231 are arranged in a circumferential direction along the outer edge of the connecting frame 23, the side of the column body 21 near the connecting frame 23 is provided with a mounting port 211, the side of the column body 21 is provided with a guide rail assembly 24, the guide rail assembly 24 includes a first guide rail 241, and the first guide rail 241 extends along the length direction of the column body 21.

[0055] Based on the above structure, in this embodiment, the column 2 adopts an inner connection structure, the connecting frame 23 is welded on the rib plate 22 at the end face of the column body 21, and during installation, as shown in the drawings, Figure 11As shown, the adjacent column 21 is connected in up and down, a pair of connecting frames 23 arranged on the end face of the column 21 are attached to each other, the mounting holes 231 on both sides are corresponding one by one, the installer passes through the mounting hole 231 on the corresponding connecting frame 23 to connect and fix by using the connecting piece through the mounting hole 211 on the side of the column 21, so as to realize the connection. Since the mounting hole 231 is inside the outer edge of the column 21, there is no protruding structure on the outside of the main body when the connection is completed, which does not affect the arrangement of the guide rail assembly 24 and will not affect the movement space of the guide wheel assembly passing through the guide rail assembly 24. In addition, the mounting hole 231 is arranged along the outer edge of the connecting frame 23 in a circumferential direction, forming a fully enclosed connection structure, which has good structural stability and can adapt to the load requirements of the super heavy load type stacking machine.

[0056] In combination Figure 7 As shown, in the embodiment, the connecting frame 23 includes a group of connecting blocks 230 which are circumferentially spliced. The group of connecting blocks 230 are strip-shaped and circumferentially form a rectangle which is adapted to the cross section of the column 21. The strip-shaped connecting blocks 230 are easy to process, can ensure the tolerance requirements of the mounting surface, and save the processing cost of the mounting surface.

[0057] In the embodiment, a positioning block 25 is further included, the positioning block 25 is provided with a positioning hole 251, the positioning block 25 is fixed on the side of the rib plate 22 close to the connecting frame 23, and the number of the positioning holes 251 is at least 2. During installation, a positioning pin is arranged on the positioning hole 251, and when the column 21 is connected, the positioning pin is arranged in the positioning hole 251 on the end face of the upper and lower two sections of the column 21, so as to realize the positioning of the upper and lower two sections of the column 21 and improve the connection efficiency. In the embodiment, the number of the positioning holes 251 is 2, and the positioning blocks 25 are arranged in pairs, and each positioning block 25 is provided with one positioning hole 251.

[0058] In the embodiment, a cover plate is further included, and the cover plate is arranged on the mounting hole 211. During dismounting operation, the cover plate is removed, and after the operation is completed, the cover plate is arranged on the mounting hole 211 to prevent foreign matters from entering the mounting hole 211.

The second mounting hole is a threaded hole, and the first mounting hole 2410 is a light hole. Because the first mounting hole 2410 has a larger diameter than the second mounting hole, there is a certain adjustment space when installing the first guide rail 241, so as to ensure the position accuracy of the first guide rail 241. After the position accuracy of the first guide rail 241 is adjusted, the spacer plate 2412 is welded on both sides of the first guide rail 241. When the first guide rail 241 is replaced later, the first guide rail 241 can be directly placed between the two spacer plates 2412, without the need for further accuracy adjustment, thereby achieving the effect of rapid positioning.

[0075] The walking guide wheel mechanism is an important component of the stacker lower crossbeam, and directly affects the service life of the overall driving mechanism. Most of the existing stacker lower crossbeams use a single guide wheel structure. For example, a Chinese patent application with the application number 202210224316.3 discloses a super-heavy single-track four-wheel stacker lower crossbeam assembly. It discloses the following technical solution: "The walking wheel box is also provided with a walking guide assembly. The walking guide assembly includes guide wheels arranged on both sides of the single track and walking along the side surface of the single track. The two guide wheels are respectively provided with a vertical connecting shaft, and the two connecting shafts are connected to a horizontal fixed connecting plate. The upper surface of the fixed connecting plate is fixedly connected with two vertical mounting plates, and the two mounting plates are tightly attached to the inner side surfaces of the two side plates and are fixedly installed with the side plates. The axis of the connecting shaft is perpendicular to the axis of the rotary connecting shaft. The walking guide assembly is arranged between the driving wheel and the driven wheel to guide the walking of the walking wheel box." The single-wheel structure of the lower crossbeam guide wheel described in the above technical solution cannot be applied to super-heavy stackers due to insufficient bearing capacity. Increasing the size of the guide wheel to adapt to the load will result in an excessively large guide wheel size and excessive installation space.

In the embodiment, a pair of lower guide wheels 482 are installed on each side of the guide wheel device 48, and a pair of the lower guide wheels 482 are in contact with the sidewall of the roadway track 49 at the same time. When bearing the same lateral force, the double-wheel structure can greatly reduce the space occupation compared with the single-wheel structure, and can bear a larger lateral force. Moreover, the rotation centers of the pair of lower guide wheels 482 on the guide wheel device 48 and the rotation centers of the swing wheel frame 481 and the fixed frame 483 form an isosceles triangle structure, the swing wheel frame 481 is rotatably connected with the fixed frame 483, compared with the rigid connection of the swing wheel frame 481 and the fixed frame 483, can absorb a certain lateral impact generated by the unevenness in the extension direction of the roadway track 49, and can improve the service life of the guide wheel device 48.

[0084] In the embodiment, the wheel body 52 of the driving box 5 is arranged in pairs, and a pair of axle holes 5111 is arranged on each side plate 511. The installation sequence is as follows: the wheel shaft 55 is arranged on the wheel body 52 to form an integral whole, and enters from the side of the box body 51, the width of the open axle slot 5112 is adapted to the diameter of the corresponding position of the wheel shaft 55, for the transverse penetration of the wheel shaft 55 into the axle hole 5111, and after the wheel shaft 55 enters the axle hole 5111, the shaft sleeve 53 is installed into the axle hole 5111 along the axial direction of the wheel shaft 55, and the inner ring of the shaft sleeve 53 is sleeved on the outer side of the wheel shaft 55, so as to realize the radial positioning of the wheel shaft 55. Compared with the structure of the semicircular movable seat and the semicircular fixed seat in the lower cross beam assembly of the super-heavy single-track four-wheel stacker disclosed in the Chinese invention patent application file with the application number 202210224316.3, in the embodiment, the shaft sleeve 53 is an integral piece, the inner ring thereof corresponding to the wheel shaft 55 has simple processing technology, low processing cost, and good replaceability. Moreover, the wheel shaft 55 and the wheel body 52 can be integrally entered into the box body 51 during installation, which is convenient for rapid disassembly and assembly. In the embodiment, the wheel shaft 55 corresponding to the driving wheel 521 extends to the side of the driving motor 54 and penetrates out, and is in transmission connection with the output end of the driving motor 54.
