Description

Technical Field

[0001] This application relates to the field of warehousing equipment technology, and in particular to a stacker crane guide rail device and a stacker crane. Background Technology

[0002] Stacker cranes are the core equipment for storing and retrieving goods in automated racking systems. They are specialized cranes that use forks to move goods from high-level racks, and the guide rail mechanism is a key component of stacker cranes.

[0003] Due to manufacturing and assembly errors, the guide wheels on the guide rail guiding mechanism may have gaps with the guide rail when they are assembled onto the guide rail. This causes the stacker crane to tilt, ultimately affecting its normal operation. Summary of the Invention

[0004] The purpose of this application is to provide a stacker crane guide rail guiding device and a stacker crane to solve at least one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this application provides a stacker crane guide rail guiding device and a stacker crane. In a first aspect, this application provides a stacker crane guide rail guiding device, including a mounting bar, a first adjusting component and two sets of guide wheel assemblies.

[0006] Both sets of guide wheel assemblies are slidably disposed on the mounting strip along a first direction. The first adjustment assembly connects the two sets of guide wheel assemblies and is adapted to adjust the relative distance between the two sets of guide wheel assemblies on the mounting strip.

[0007] In the above process, two sets of guide wheel assemblies are slidably mounted on the mounting strip along the first direction. The operator can adjust the relative distance between the two guide wheel assemblies through the first adjustment component to make the two guide wheel assemblies move closer or further apart (which can be understood as moving closer and abutting against the guide rail). Ultimately, both guide wheel assemblies can fully abut against the guide rail to accommodate errors caused by manufacturing and assembly, and to avoid tilting caused by gaps between the guide wheel assemblies and the guide rail.

[0008] Preferably, the guide wheel assembly includes a guide wheel body and a slider, the slider being slidably disposed on the mounting strip and having a mounting portion formed on the slider;

[0009] The guide wheel body is rotatably mounted on the slider and is adapted to abut against the guide rail. The slider is hinged to the first adjustment component through the mounting part.

[0010] In the above implementation process, the guide wheel body is mounted on the slider, the slider is slidably mounted on the mounting strip, the slider is hinged to the first adjustment component through the mounting part, and the first adjustment component adjusts the position of the guide wheel body by adjusting the position of the slider so that the guide wheel body can fully abut against the guide rail; of course, it is understood that the guide wheel body here does not refer to a single one, but may include multiple ones.

[0011] Preferably, the first adjustment assembly includes a connecting block, a connecting rod, and a first adjustment member;

[0012] One end of the connecting rod is hinged to the connecting block, and the other end is hinged to the slider;

[0013] The first adjusting member is adapted to drive the connecting block to move in the second direction so as to drive the guide wheel assembly to move in the first direction;

[0014] In the above implementation process, the first adjusting member can adjust the relative position between the connecting block and the mounting strip. When the connecting block moves away from the mounting strip, the connecting block drives the slider to move through the connecting rod, which can be further understood as moving closer to each other, so that the guide wheel body moves closer to the guide rail side, and finally the guide wheel body can fully abut against the guide rail; conversely, if the connecting block is adjusted towards the side closer to the mounting strip by the first adjusting member, the two guide wheel assemblies can be moved away from each other.

[0015] Preferably, it further includes a second adjustment component, which is disposed on the mounting strip and is adapted to drive the first adjustment component and the two sets of guide wheel assemblies to move along the first direction;

[0016] In the above implementation process, the adjustment process of the first adjustment component can be understood as moving the two guide wheel components closer to or further away from each other to adjust the distance between the two guide wheel components, while the second adjustment component can make the two guide wheel components adjust their positions simultaneously along one direction; with the cooperation of the first and second adjustment components, the fit between the two guide wheel components and the guide rail can be better, thereby further reducing the risk of tilting due to the existence of gaps.

[0017] Preferably, the first adjustment assembly includes a connecting block, a connecting rod, and a first adjustment member;

[0018] One end of the connecting rod is hinged to the connecting block, and the other end is hinged to the slider;

[0019] The first adjusting member passes through the mounting strip along the second direction and is adapted to drive the connecting block to move along the second direction so as to drive the guide wheel assembly to move along the first direction. A waist-shaped hole is provided on the mounting strip along the first direction for the first adjusting member to pass through.

[0020] The second adjustment component includes a first screw and a second screw distributed along a first direction and arranged opposite to each other, with one end of the first screw and the second screw respectively abutting against the outer peripheral wall of the first adjustment component;

[0021] The axial directions of the first screw and the second screw are parallel to the first direction;

[0022] In the above process, the operator can first use the first adjusting member to move the two guide wheel bodies closer to one side of the guide rail until one of the guide wheel bodies abuts against the guide rail. If there is a certain gap between the other guide wheel body and the guide rail, taking the screw closest to the gap as the first screw as an example, the operator can rotate the first screw to move it closer to the first adjusting member in the first direction, and rotate the second screw to move it away from the first adjusting member in the first direction. The first adjusting member drives the two guide wheel assemblies to move in the same direction through the connecting block. At this time, the gap that existed before is gradually reduced, and a certain gap is generated on the other side. At this time, the first adjusting member can be used again to adjust the two guide wheel assemblies closer to each other, so that both guide wheel assemblies can fully abut against the guide rail. In addition, the waist-shaped hole formed on the mounting strip allows the first adjusting member to move along the first direction without being obstructed.

[0023] Preferably, the outer peripheral wall of the first adjusting member is formed with threads;

[0024] It also includes a nut that is threadedly engaged with the first adjusting member, wherein the first adjusting member is sequentially inserted into the threaded hole of the waist-shaped hole and the nut along the second direction;

[0025] The end of the nut away from the connecting block abuts against the mounting strip;

[0026] In the above implementation process, the first adjusting member is sequentially inserted into the threaded hole of the waist-shaped hole and the nut along the second direction. Without adjustment, the nut prevents the first adjusting member from moving away from the connecting block. When adjustment is performed, the first adjusting member can be adjusted in the second direction by fixing the nut and rotating the first adjusting member or fixing the first adjusting member and rotating the nut, thereby adjusting the distance between the connecting block and the mounting strip, and finally adjusting the distance between the two guide wheel assemblies.

[0027] Preferably, a limiting portion is formed at the end of the first adjusting member away from the connecting block;

[0028] The limiting part is clearance-fitted with the waist-shaped hole, and the two opposite sidewalls of the limiting part abut against the long side of the waist-shaped hole respectively;

[0029] In the above process, the gap fit between the waist-shaped hole and the limiting part prevents the first adjusting member from rotating, but it can move along the long side of the waist-shaped hole and the first direction. At this time, the operator can rotate the nut to make the first adjusting member move along the second direction. After the first adjusting member is limited, its movement process is more stable, which is conducive to improving the adjustment accuracy.

[0030] Preferably, it also includes a pin and a retaining ring; one end of the pin extends radially to form a retaining platform; an annular groove is formed around the pin on the outer peripheral wall of the end of the pin away from the retaining platform.

[0031] The pin is located at the hinge at both ends of the connecting rod; the snap ring is adapted to snap into the annular groove and cooperate with the snap plate to form a limit, so as to connect the connecting rod and the slider and the connecting rod and the connecting block;

[0032] In the above implementation process, taking the hinge joint between the connecting rod and the connecting block as an example, the pin can be inserted through the connecting rod and the hinge block until the locking plate on the pin abuts against the connecting block. On the outer peripheral wall of the other end of the pin away from the locking plate, a structure similar to the locking plate can be formed by the retaining spring, thereby forming a limit between the locking plate and the retaining spring, ultimately connecting the pin, the connecting rod, and the connecting block into one unit, and both the connecting rod and the connecting block can rotate around the pin.

[0033] Preferably, a positioning hole adapted to the end of the first adjusting member is formed on the side of the connecting block near the mounting strip;

[0034] In the above implementation process, the positioning hole enables the first adjusting component to be positioned quickly, thereby improving the assembly speed; and in some applications, such as applications where the first adjusting component can be rotated, the positioning hole can also be threaded to achieve connection with the first adjusting component.

[0035] Preferably, the first direction and the second direction are perpendicular to each other.

[0036] Secondly, this application provides a stacker crane, including a stacker crane guide rail device as described above.

[0037] Preferably, a countersunk hole is provided on the mounting strip;

[0038] It also includes a mounting beam, the mounting strip being adapted to be fixed to the mounting beam through the countersunk hole.

[0039] Compared with the prior art, the beneficial effects of this application are as follows: In this solution, two sets of guide wheel assemblies are slidably mounted on the mounting strip along the first direction. The operator can adjust the relative distance between the two guide wheel assemblies through the first adjustment component to make the two guide wheel assemblies move closer or further apart, so that both guide wheel assemblies can fully abut against the guide rail to accommodate the errors caused by manufacturing and assembly, and avoid the problem of tilting caused by the gap between the guide wheel assembly and the guide rail.

[0056] Example

[0057] Due to manufacturing and assembly errors, gaps may occur between the guide wheels on the guide rail guiding mechanism and the guide rail when they are assembled onto the guide rail. This causes the stacker crane to tilt, ultimately affecting its normal operation. To solve the above technical problem, this embodiment provides the following technical solution:

[0058] Please see Figure 1-7 This embodiment provides a stacker crane guide rail guiding device, including a mounting bar 10, a first adjusting component 20, and two sets of guide wheel assemblies 30;

[0059] Specifically, in some implementations, the guide rail can be further understood as a ceiling track;

[0060] Specifically, both sets of guide wheel assemblies 30 are slidably disposed on the mounting strip 10 along the first direction, and the first adjustment assembly 20 connects the two sets of guide wheel assemblies 30 and is adapted to adjust the relative distance between the two sets of guide wheel assemblies 30 and the mounting strip 10;

[0061] In the above scheme, two sets of guide wheel assemblies 30 are slidably mounted on the mounting strip 10 along the first direction. The operator can adjust the relative distance between the two guide wheel assemblies 30 through the first adjustment component 20, so that the two guide wheel assemblies 30 can move closer or further away from each other, so that the two guide wheel assemblies 30 can fully abut against the guide rail, in order to adapt to the errors caused by manufacturing and assembly, and avoid the problem of tilting caused by the gap between the guide wheel assembly 30 and the guide rail.

[0062] It is understandable that in practical applications, the adjustment is more about bringing the guide wheel assembly 30 closer to the guide rail. Therefore, the adjustment of the two guide wheel assemblies 30 is more about bringing them closer together rather than moving them apart.

[0063] Furthermore, in some embodiments, the first adjustment component 20 may only have the function of adjusting the two guide wheel assemblies 30 to move closer to each other, without having the function of adjusting the two guide wheel assemblies 30 to move closer to each other and further apart at the same time.

[0064] For details, please see Figure 4 The guide wheel assembly 30 includes a guide wheel body 31 and a slider 32. The slider 32 is slidably disposed on the mounting strip 10 and a mounting portion 321 is formed on the slider 32.

[0065] Furthermore, the guide wheel body 31 is rotatably mounted on the slider 32 and is adapted to abut against the guide rail. The slider 32 is hinged to the first adjustment assembly 20 through the mounting part 321.

[0066] In the above scheme, the guide wheel body 31 is mounted on the slider 32, the slider 32 is slidably mounted on the mounting strip 10, the slider 32 is hinged to the first adjustment component 20 through the mounting part 321, and the first adjustment component 20 adjusts the position of the guide wheel body 31 by adjusting the position of the slider 32, so that the guide wheel body 31 can fully abut against the guide rail.

[0067] It is understood that the guide wheel body 31 here does not refer to a single one, but may include multiple ones. For example, in some embodiments, multiple guide wheel bodies 31 are arranged side by side. However, it can be further understood that multiple guide wheel bodies 31 all abut against the guide rail.

[0068] Specifically, in some embodiments, the first adjustment component 20 includes a connecting block 21, a connecting rod 22, and a first adjustment member 23;

[0069] Furthermore, one end of the connecting rod 22 is hinged to the connecting block 21, and the other end is hinged to the slider 32;

[0070] Furthermore, the first adjusting member 23 is adapted to drive the connecting block 21 to move in the second direction so as to drive the guide wheel assembly 30 to move in the first direction;

[0071] In the above scheme, the first adjusting member 23 can adjust the relative position between the connecting block 21 and the mounting strip 10. When the connecting block 21 moves away from the mounting strip 10, the connecting block 21 drives the slider 32 to move through the connecting rod 22, which can be further understood as moving closer to each other, so that the guide wheel body 31 can move closer to the guide rail, and finally the guide wheel body 31 can fully abut against the guide rail; conversely, if the connecting block 21 is adjusted towards the side closer to the mounting strip 10 by the first adjusting member 23, the two guide wheel assemblies 30 can be moved away from each other.

[0072] Specifically, a rotating shaft 322 is formed on the slider 32, and the guide wheel body 31 is rotatably mounted on the slider 32 via the rotating shaft 322.

[0073] In one embodiment, the first adjusting member 23 is a screw with threads at its end. The end of the first adjusting member 23 near the connecting block 21 is rotatably connected to the connecting block 21. The first adjusting member 23 is threadedly engaged with the mounting strip 10. That is, by rotating the first adjusting member 23, the first adjusting member 23 can be moved along the second direction, which in turn drives the connecting block 21 to move along the second direction. The connecting block 21 drives the slider 32 to slide along the first direction through the connecting rod 22, thereby adjusting the position of the guide wheel body 31.

[0074] In some embodiments, the first adjusting member 23 is not directly connected to the connecting block 21. The first adjusting member 23 abuts against the connecting block 21, which can be further understood as abutting against the side of the connecting block 21 near the mounting strip 10. In this case, the first connecting member mainly prevents the connecting block 21 from moving towards the mounting strip 10, and the first adjusting member 23 can move further towards the connecting block 21 to drive the two guide wheel assemblies 30 to move closer to each other. However, the adjustment of the two guide wheel assemblies 30 moving away from each other cannot be directly achieved in this embodiment. But it is understood that in practical applications, it is more necessary for the two guide wheel assemblies 30 to move closer to each other rather than away from each other, so as to reduce the gap between the guide wheel assembly 30 and the guide rail.

[0075] To further improve the installation accuracy of the stacker crane guide rail guiding device, and to better align the guide wheel assembly 30 with the guide rail, thereby reducing gaps, this embodiment provides the following technical solution:

[0076] For details, please see Figure 2 and Figure 4 It also includes a second adjustment component 40, which is disposed on the mounting strip 10 and is adapted to drive the first adjustment component 20 and the two sets of guide wheel assemblies 30 to move along the first direction;

[0077] In the above scheme, the adjustment process of the first adjustment component 20 can be understood as moving the two guide wheel assemblies 30 closer to each other or further away to adjust the distance between the two guide wheel assemblies 30. The second adjustment component 40 can adjust the position of the two guide wheel assemblies 30 simultaneously in one direction. With the cooperation of the first adjustment component 20 and the second adjustment component 40, the fit between the two guide wheel assemblies 30 and the guide rail can be better, thereby further reducing the risk of tilting due to the existence of gaps.

[0078] Understandably, under the adjustment of the first adjustment component 20, even if there is a certain gap between the guide wheel body 31 and the guide rail, this gap is negligible compared to the gap caused by existing installation and manufacturing errors. The second adjustment component 40 in this solution can further reduce this gap and achieve high-precision installation in conjunction with the first adjustment component 20.

[0079] Furthermore, in some embodiments, the first adjusting member 23 passes through the mounting strip 10 in the second direction and is adapted to drive the connecting block 21 to move in the second direction so as to drive the guide wheel assembly 30 to move in the first direction. A waist-shaped hole 12 is provided on the mounting strip 10 in the first direction for the first adjusting member 23 to pass through.

[0080] Furthermore, the second adjustment component 40 includes a first screw 41 and a second screw 42 distributed along the first direction and arranged opposite to each other, with one end of the first screw 41 and the second screw 42 respectively abutting against the outer peripheral wall of the first adjustment member 23;

[0081] Furthermore, the axes of the first screw 41 and the second screw 42 are parallel to the first direction;

[0082] In the above scheme, the operator can first use the first adjusting member 23 to move the two guide wheel bodies 31 closer to one side of the guide rail until one of the guide wheel bodies 31 abuts against the guide rail. If there is a certain gap between the other guide wheel body 31 and the guide rail, taking the screw close to the gap as the first screw 41 as an example, the operator can rotate the first screw 41 to move it closer to the first adjusting member 23 in the first direction, and rotate the second screw 42 to move it away from the first adjusting member 23 in the first direction. The first adjusting member 23 drives the two guide wheel assemblies 30 to move in the same direction through the connecting block 21. At this time, the gap that existed before is gradually reduced, and a certain gap is generated on the other side. At this time, the first adjusting member 23 can be used again to adjust the two guide wheel assemblies 30 closer to each other, so that both guide wheel assemblies 30 can fully abut against the guide rail. In addition, the waist-shaped hole 12 formed on the mounting strip 10 allows the first adjusting member 23 to move along the first direction without being obstructed.

[0083] In other embodiments, a single screw can also be provided, such as a U-shaped groove formed at the end of the screw near the first adjusting member 23, and the first adjusting member 23 passes through the U-shaped groove and abuts against the two opposing inner walls of the U-shaped groove. In this case, only a single screw is needed to achieve the adjustment of the first adjusting member 23 in two positions in the first direction.

[0084] Of course, the above are only some embodiments of the second adjustment component 40, and this solution does not limit its specific application.

[0085] Specifically, in some embodiments, the first adjusting member 23 has a thread at one end near the connecting block 21;

[0086] Furthermore, it also includes a nut 24 that is threadedly engaged with the first adjusting member 23, wherein the first adjusting member 23 is sequentially inserted into the threaded hole of the waist-shaped hole 12 and the nut 24 along the second direction;

[0087] Specifically, the end of the nut 24 away from the connecting block 21 abuts against the mounting strip 10;

[0088] In the above scheme, the first adjusting member 23 is sequentially inserted into the threaded holes of the waist-shaped hole 12 and the nut 24 along the second direction. Without adjustment, the nut 24 prevents the first adjusting member 23 from moving away from the connecting block 21. During adjustment, the first adjusting member 23 can be adjusted in the second direction by fixing the nut 24 and rotating the first adjusting member 23, or vice versa. This adjusts the distance between the connecting block 21 and the mounting strip 10, ultimately adjusting the distance between the two guide wheel assemblies 30. It is understood that this embodiment is applicable to implementations where the first adjusting member 23 cannot rotate; in this case, the adjustment of the first adjusting member 23 in the second direction can be achieved by rotating the adjusting nut 24.

[0089] It should be noted that in the above embodiment, the nut 24 is only provided between the connecting block 21 and the mounting strip 10, and no additional nut 24 is provided on the side of the mounting strip 10 away from the connecting block 21. It is understood that in practical applications, the ultimate goal of this application is to allow the two guide wheel assemblies to fully abut against the guide rail, and the guide rail to provide a reaction force to the two guide wheel assemblies. Under this reaction force, the connecting block 21 has a tendency to drive the first adjusting member 23 to move along the side where the mounting strip 10 is located. Therefore, this solution only provides the nut 24 between the connecting block 21 and the mounting strip 10. The nut 24 and the first adjusting member 23 form a relatively fixed state, and the nut 24 itself abuts against the side wall of the mounting strip 10, which can ultimately prevent the first adjusting member 23 from moving away from the connecting block 21.

[0090] Furthermore, in some embodiments, the first direction and the second direction are perpendicular to each other.

[0091] For details, please see Figure 3 and Figure 6 The first adjusting member 23 has a limiting part 231 at the end away from the connecting block 21;

[0092] The further limiting part 231 is clearance-fitted with the waist-shaped hole 12, and the two opposite side walls of the limiting part 231 respectively abut against the long side of the waist-shaped hole 12;

[0093] In the above scheme, the gap fit between the waist-shaped hole 12 and the limiting part 231 prevents the first adjusting member 23 from rotating, but it can move along the long side of the waist-shaped hole 12 and the first direction. At this time, the operator can rotate the nut 24 to make the first adjusting member 23 move along the second direction. After the first adjusting member 23 is limited, its movement process is more stable, which is conducive to improving the adjustment accuracy.

[0094] Specifically, threads are formed on the outer peripheral wall of the first adjusting member 23; see also Figure 6In some embodiments, the limiting part 231 may be partially threaded, while the end away from the limiting part 231 is merely a smooth wall surface that mates with the positioning hole; of course, in other embodiments, the outer peripheral wall near the end of the connecting block may be threaded; it is understood that the thread formed on the outer peripheral wall of the first adjusting member 23 is intended to achieve threaded engagement with the nut 24, and this application does not limit the specific location of the thread on the first adjusting member 23, or whether it is partially or entirely threaded.

[0095] For details, please see Figure 4 In some embodiments, the mounting portion 321 formed on the slider 32 can be understood as a connecting ear. A first through hole 3211 is provided on the connecting ear, a second through hole 221 is provided at both ends of the connecting rod 22, and a third through hole (not shown in the figure) is provided on the connecting block 21.

[0096] Please see Figure 4-5 It also includes a pin 50 and a retaining ring 60; one end of the pin 50 extends radially to form a retaining platform 51; an annular groove 52 is formed around the pin 50 on the outer peripheral wall of the end of the pin 50 away from the retaining platform 51.

[0097] Furthermore, the pin 50 is provided at the hinge at both ends of the connecting rod 22; the snap ring 60 is adapted to snap into the annular groove 52 and cooperate with the snap ring 51 to form a limit, so as to connect the connecting rod 22 with the slider 32 and the connecting rod 22 with the connecting block 21.

[0098] Furthermore, the pin 50 passes through the first through hole 3211 and the second through hole 221, and cooperates with the snap ring 60 to connect the slider 32 and the connecting rod 22. The pin 50 passes through the second through hole 221 and the third through hole, and cooperates with the snap ring 60 to connect the connecting block 21 and the connecting rod 22.

[0099] In the above scheme, taking the hinge joint between the connecting rod 22 and the connecting block 21 as an example, the pin 50 can be inserted through the connecting rod 22 and the hinge block until the locking platform 51 on the pin 50 abuts against the connecting block 21. The outer peripheral wall of the other end of the pin 50 away from the locking platform 51 can be formed with a retaining spring 60 to form a structure similar to the locking platform 51, thereby forming a limit between the locking platform 51 and the retaining spring 60, ultimately connecting the pin 50, the connecting rod 22, and the connecting block 21 into one unit. Both the connecting rod 22 and the connecting block 21 can rotate around the pin 50.

[0100] Furthermore, multiple annular grooves 52 may be provided and distributed along the axial direction of the pin 50; and the operator may engage the snap ring 60 in the annular groove 52 at a suitable position according to the actual situation, thereby making flexible adjustments according to the actual situation.

[0101] Specifically, a positioning hole adapted to the end of the first adjusting member 23 is formed on the side of the connecting block 21 near the mounting strip 10;

[0102] In the above scheme, the positioning hole enables the first adjusting member 23 to be quickly positioned, thereby improving the assembly speed; in some applications, such as applications where the first adjusting member 23 can be rotated, the positioning hole can also be threaded to achieve connection with the first adjusting member 23.

[0103] In some embodiments, the positioning hole is fully adapted to the end of the first adjusting member 23, that is, when the first adjusting member 23 moves along the first direction, it can drive the connecting block 21 to move synchronously along the first direction, and the connecting block 21 can drive the two guide wheel assemblies to move synchronously through the connecting rod 22.

[0104] This embodiment also provides a stacker crane, which includes any of the stacker crane guide rail guiding devices described above.

[0105] For details, please see Figure 7 A countersunk hole 11 is provided on the mounting strip 10;

[0106] Furthermore, it also includes a mounting beam 70, and the mounting strip 10 is adapted to be fixed to the mounting beam 70 through the countersunk hole 11;

[0107] Specifically, in some implementations, multiple stacker crane guide rail guiding devices may be provided and arranged along the length of the guide rail.

[0108] Furthermore, in some embodiments, the stacker crane guide rail guide device is provided in two parts, and is respectively located near both ends of the crossbeam;

[0109] Furthermore, the connecting blocks of the two stacker crane guide rollers are positioned far apart from each other. In this embodiment, the two connecting blocks 21 are positioned far apart from each other, which means that the nuts 24 are also positioned far apart from each other. This can be further understood as the connecting blocks 21 and the nuts 24 being positioned towards the outer end of the crossbeam 70 rather than towards the inner end. In practical applications, positioning the nuts 24 towards the outer end of the crossbeam 70 rather than towards the inner end makes it easier for workers to adjust the nuts 24. It is understood that when the nuts 24 are positioned close to the inner end, the workers will find it inconvenient to adjust them due to the obstruction of the guide rail, which will affect work efficiency. However, through the further improvement of this embodiment, the convenience of adjustment can be effectively improved, thereby improving the adjustment efficiency.

[0110] Furthermore, although multiple guide wheel bodies 31 can be provided in the guide wheel assembly 30, one is preferred; multiple stacker crane guide rail guiding devices can be provided instead of multiple guide wheel bodies 31 in one guide wheel assembly 30; this can avoid errors between multiple guide wheel bodies 31 in one guide wheel assembly 30, which would prevent them from being completely fitted to the guide rail; and a single guide wheel assembly 30 with a single guide wheel body 31 can accurately achieve adjustment.

[0111] It should be noted that the other mechanisms in the stacker crane are relatively mature technologies in the existing technology, so this solution will not elaborate on the other mechanisms and their specific working principles.

[0112] Specifically, the following is one of the installation methods of the stacker crane guide rail guiding device provided in this embodiment:

[0113] S1. Fix the mounting strip 10 to the crossbeam 70 of the stacker crane;

[0114] Specifically, countersunk screws can be used to pass through the countersunk holes 11 of the mounting strip 10 for installation; it is understood that this fixing installation method is only one of them, and this embodiment does not limit the specific fixing installation method; in some embodiments, welding can also be used.

[0115] S2. Assemble the sliders 32 of the two sets of guide wheel assemblies 30 onto the mounting strip 10 along the first direction, so that they are located on both sides of the guide rail respectively.

[0116] Specifically, in some embodiments, the slider 32 is formed with a through groove into which the mounting strip 10 can pass.

[0117] S3. Connect the connecting block 21, the connecting rod 22 and the guide wheel assembly 30 through the pin 50;

[0118] Specifically, it is understandable that using pin 50 in conjunction with snap ring 60 is just one method of fixing the connection.

[0119] S4. Place the nut 24 on the side of the mounting strip 10 near the connecting block 21, and let the first adjusting member 23 pass through the waist-shaped hole 12, the threaded hole on the nut 24 and the positioning hole on the connecting block 21 in sequence.

[0120] Specifically, as described above, setting nut 24 is only one implementation method, and nut 24 may not be set in other implementation methods; in this implementation method, the adjustment of the first adjusting member 23 in the second direction can be achieved by using nut 24.

[0121] S5. The distance between the two guide wheel assemblies 30 is controlled by adjusting the first adjusting member 23, so that the two guide wheel assemblies 30 move closer to each other so that the guide wheel body 31 fits against the guide rail.

[0122] Furthermore, in some embodiments, if the two guide wheel assemblies 30 can be perfectly symmetrical with the guide rail, and the distance between the two guide wheel bodies 31 and the guide rail is equal, then under the adjustment of the first adjustment component 20, the two road bodies move closer to each other and move the same distance toward the guide rail, and finally the two guide wheel bodies 31 can just abut against the guide rail.

[0123] In other embodiments, the distances of the two guide wheel assemblies 30 from the guide rail are not equal. In this case, the second adjustment component 40 can be used to further adjust the distances of the two guide wheel assemblies 30 from the guide rail to be equal, and then the first adjustment component 20 can be used to adjust again. Alternatively, the guide wheel body 31 of one of the guide wheel assemblies 30 can be placed against the guide rail first, and then the second adjustment component 40 can be used to finely adjust the positions of the two guide wheel assemblies 30 in the same direction to adjust the gaps on both sides of the guide rail to be equal. Finally, the first adjustment component 20 can be used to ensure that both guide wheel assemblies 30 are fully against the guide rail.

[0124] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0125] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application shall fall within the scope of the technical solution of this application.
