Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a stacker crane with a centering positioning function. Background Technology

[0002] In the current cigarette manufacturing process, stacker cranes are widely used in filter rod transportation due to their flexibility, efficiency, safety, reliability, and wide applicability. However, the operational stability of the stacker crane significantly impacts the filter rod transportation efficiency; therefore, ensuring the normal and steady-state operation of the entire stacker crane is crucial.

[0003] As the core component of the stacker crane, the traveling mechanism moves linearly on the ground rail via a pair of traveling wheels. A guiding mechanism is needed to guide the traveling mechanism's movement on the ground rail, ensuring its straightness and accuracy. Due to the heavy load on the traveling wheels and the relative friction between the guiding mechanism and the ground rail, the traveling wheels and guiding mechanism are prone to damage and wear during long-term operation of the stacker crane. Therefore, it is necessary to stop the machine for disassembly, maintenance, and replacement of the traveling wheels and guiding mechanism to ensure the overall operational stability of the stacker crane.

[0004] After reinstalling the traveling wheels and guide mechanism, the entire traveling mechanism needs to be re-centered on the ground rail to ensure the straightness and accuracy of the traveling mechanism's movement. However, since the traveling mechanism is usually centered by manually measuring with a ruler, there are problems such as low positioning accuracy, time and labor costs, high labor costs, and low maintenance efficiency.

[0005] To address the above problems, there is an urgent need for a stacker crane with a centering positioning function for roadways. Utility Model Content

[0006] The purpose of this invention is to propose a stacker crane with a centering positioning function in a roadway, which can ensure good centering positioning accuracy of the traveling mechanism, resulting in high positioning accuracy, saving time and labor, lower labor costs, and higher maintenance efficiency.

The bottom ends of the first fixing plate and the bottom ends of the second fixing plate are both provided with opening slots extending along the X-axis. The two opening slots form the sliding groove.

[0019] As an optional solution, the top ends of the first fixing plate and the second fixing plate are respectively recessed downward along the Z-axis, and the two support platforms are arranged opposite each other along the Y-axis. The support platforms are used to support the bracket when the traveling wheel and / or the guide mechanism are removed.

[0020] As an optional feature, the first fixing plate is also provided with an inclined surface, which is located between the two support platforms and is used to allow the traveling wheels to pass through to enter and exit the bracket.

[0021] As an optional solution, the positioning component includes:

[0022] The first positioning component has one end mounted on the top surface of the first fixed plate and the other end extending along the X-axis to the traveling wheel. The other end of the first positioning component can be closely attached to one side of the traveling wheel along the Y-axis.

[0023] The second positioning component has one end mounted on the top surface of the second fixing plate and the other end extending along the X-axis to the traveling wheel. The other end of the second positioning component can be tightly attached to the other side of the traveling wheel along the Y-axis.

[0024] As an optional solution, the structure of the first positioning member is the same as that of the second positioning member; the first positioning member includes:

[0025] The base is connected to the top surface of the first fixed plate and located on the rear side of the support platform;

[0026] A positioning plate is connected to the base. The positioning plate is used to be in close contact with the side of the walking wheel along the Y-axis. The positioning plate of the first positioning member and the positioning plate of the second positioning member are parallel and opposite to each other along the Y-axis. The center line between the two positioning plates on the X-axis coincides with the center line of the ground rail.

[0027] A reinforcing plate is connected between the base and the positioning plate.

[0028] As an optional solution, the stop bar assembly includes:

[0029] The first stop bar has one end connected to the base of the first positioning member and the other end extending along the X-axis to the bracket. The other end of the first stop bar can be closely attached to one side of the bracket along the Y-axis.

[0030] The second stop bar has one end connected to the base of the second positioning member and the other end extending along the X-axis to the bracket. The other end of the second stop bar can be tightly attached to the other side of the bracket along the Y-axis.

[0031] As an optional embodiment, the structure of the first stop bar is the same as that of the second stop bar; the first stop bar includes:

[0032] Mounting plate, connected to one side of the base of the first positioning member;

[0033] A baffle is vertically connected to the mounting plate to form an L-shaped first baffle. At least a portion of the baffle is placed on the top surface of the first fixing plate and located on one side of the support platform. The baffle is used to be tightly attached to the side of the bracket along the Y-axis, and the first baffle and the second baffle are symmetrically arranged with respect to the X-axis.

[0034] As an optional solution, the bracket includes:

[0035] The chassis, in which the traveling wheels are rotatably connected about the Y-axis;

[0036] The base frame has two side plates protruding from opposite ends along the X-axis. The two side plates located on the same end face are spaced apart along the Y-axis. A support platform is used to support one side plate. The baffle of the first baffle and the baffle of the second baffle are respectively close to the outer side of the two side plates along the Y-axis. The end face of the base frame connected to the side plate can be positioned to block the baffle on the upper limit of the X-axis.

[0037] The beneficial effects of this utility model are as follows:

[0038] By fixing the ground rail, the traveling mechanism moves along the X-axis on the ground rail, and the guide mechanism guides the traveling mechanism's movement along the X-axis on the ground rail to ensure the straightness and accuracy of the traveling mechanism's movement. Simultaneously, before disassembling and assembling the traveling wheels and / or guide mechanism for replacement or maintenance, a centering positioning mechanism is pre-installed on the ground rail. This ensures that the center line of the traveling mechanism's bracket, the center line of the centering positioning mechanism, and the center line of the ground rail coincide on the X-axis. In other words, before disassembly and assembly, the centering positioning mechanism accurately centers and positions the traveling mechanism on the ground rail. Only on this basis can the traveling wheels and / or guide mechanism be disassembled and assembled. Because the centering positioning mechanism remains stationary on the ground rail, it ensures accurate centering of the traveling mechanism. After maintenance and reassembly of the traveling wheels and / or guide mechanism, the center lines of the traveling mechanism's bracket, the center line of the centering positioning mechanism, and the center line of the ground rail remain aligned. This allows the centering positioning mechanism to constrain the installation positions of the traveling wheels and guide mechanism, ensuring good centering accuracy of the traveling mechanism. It eliminates the need for manual ruler measurement for centering, resulting in higher positioning accuracy, saving time and effort, lower labor costs, and higher maintenance efficiency.

Detailed Implementation

[0056] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0057] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0058] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0059] This embodiment proposes a stacker crane with a centering positioning function in aisle areas. When maintenance and replacement are required, the stacker crane can ensure a high maintenance rate and high centering positioning accuracy, thereby reducing labor costs and ensuring the operational stability of the entire stacker crane.

[0060] Specifically, such as Figures 1 to 6 As shown, the stacker crane with centering positioning function includes a ground rail 1, a traveling mechanism 2, a guiding mechanism 3, and a centering positioning mechanism 4. The ground rail 1 is fixedly installed and extends along the X-axis. The traveling mechanism 2 is mounted on the ground rail 1 and can travel along the X-axis on the ground rail 1. A guiding mechanism 3 is connected to each of the four corners of the traveling mechanism 2, and two guide mechanisms 3 opposite each other along the Y-axis rotate to abut against the ground rail 1, guiding the traveling mechanism 2 to travel along the X-axis on the ground rail 1, thus ensuring the straightness and accuracy of the traveling mechanism 2. One end of the centering positioning mechanism 4 is detachably connected to the ground rail 1, and the other end of the centering positioning mechanism 4 abuts against the traveling mechanism 2 to provide centering positioning for the traveling mechanism 2. This ensures that when the traveling wheels 21 and / or the guiding mechanisms 3 of the traveling mechanism 2 are disassembled or assembled, the centerline of the bracket 23 of the traveling mechanism 2, the centerline of the centering positioning mechanism 4, and the centerline of the ground rail 1 coincide on the X-axis.

[0061] Compared to existing technologies, the stacker crane with centering positioning function in this embodiment is equipped with a centering positioning mechanism 4 that can be installed and disassembled independently. Before replacing or repairing the traveling wheels 21 and / or guide mechanism 3 of the traveling mechanism 2, the centering positioning mechanism 4 is pre-installed on the ground rail 1, ensuring that the center lines of the bracket 23 of the traveling mechanism 2, the center line of the centering positioning mechanism 4, and the center line of the ground rail 1 coincide on the X-axis. That is, before disassembly or assembly, the centering positioning mechanism 4 accurately centers and positions the traveling mechanism 2 on the ground rail 1. Then, the traveling wheels 21 and / or guide mechanism 3 are disassembled or assembled. Since the centering positioning mechanism 4 remains stationary on the ground rail 1, it ensures that the traveling mechanism 2... The accurate centering positioning effect on the ground rail 1; after maintenance and reassembly of the traveling wheel 21 and / or guide mechanism 3, since the center line of the bracket 23 of the traveling mechanism 2, the center line of the centering positioning mechanism 4 and the center line of the ground rail 1 always coincide, the installation position of the traveling wheel 21 and guide mechanism 3 can be constrained by the centering positioning mechanism 4, thereby ensuring good centering positioning accuracy of the traveling mechanism 2. It is no longer necessary to use a ruler to measure the centering positioning of the traveling mechanism 2, thus ensuring high positioning accuracy, saving time and effort, reducing labor costs and increasing maintenance efficiency, thereby improving the centering positioning accuracy of the traveling mechanism 2 and improving the operational stability of the traveling mechanism 2 and the entire roadway stacker crane with centering positioning function.

[0062] It is worth noting that the ground rail 1, guide mechanism 3, and traveling mechanism 2 in this embodiment are all common structures in existing roadway stacker cranes. Therefore, the working principles of the ground rail 1, guide mechanism 3, and traveling mechanism 2 will not be described in detail here; refer to existing roadway stacker cranes. The guide mechanism 3 can be a common guide structure with guiding function found in existing technologies.

[0063] Furthermore, such as Figures 1 to 6 As shown, the centering positioning mechanism 4 includes a fixed base 41, a positioning component 42, and a stop bar assembly. A groove 411 is formed at the bottom of the fixed base 41. The ground rail 1 slides within the groove 411 along the X-axis, allowing the fixed base 41 to be pushed relative to the ground rail 1 along the X-axis. This means the fixed base 41 and the entire centering positioning mechanism 4 can be moved manually to a suitable position along the X-axis on the ground rail 1. The positioning component 42 is connected to the fixed base 41 and is positioned along the Y-axis against the opposite sides of the traveling wheel 21 to limit the installation position of the traveling wheel 21. The stop bar assembly is connected to the positioning component 42 and located outside the positioning component 42 along the Y-axis. The stop bar assembly is positioned along the Y-axis against the opposite sides of the bracket 23 to limit the installation position of the bracket 23.

[0064] By setting up a positioning component 42 and a stop bar component that work together, the positioning component 42 and the stop bar component can respectively limit the installation position of the traveling wheel 21 and the bracket 23, thereby providing better installation limit constraints for the entire traveling mechanism 2, thereby improving the centering positioning accuracy of the traveling mechanism 2 and improving the operational stability of the traveling mechanism 2 and the entire roadway stacker crane with centering positioning function.

[0065] It is worth noting that the outer dimensions of the fixed base 41 match the outer dimensions of the ground rail 1, the outer dimensions of the positioning component 42 match the outer dimensions of the traveling wheel 21, and the outer dimensions of the baffle component match the outer dimensions of the bracket 23, so that the entire centering positioning mechanism 4 can be well adapted to the centering positioning adjustment of the traveling mechanism 2.

[0066] Furthermore, such as Figure 6 and Figure 7 As shown, the fixed base 41 includes a first fixed plate 412 and a second fixed plate 413; wherein, a recessed platform 4121 is provided on the first fixed plate 412 along the Z-axis downward, and a protruding plate 4131 is provided on the second fixed plate 413. The protruding plate 4131 is connected to the recessed platform 4121 so that the top surface of the first fixed plate 412 is flush with the top surface of the second fixed plate 413, thereby forming an integral flat plate structure to ensure the connection flatness and surface flatness of the entire fixed base 41.

[0067] Specifically, such as Figures 7 to 9 As shown, the external dimensions of the recessed platform 4121 correspond to the external dimensions of the convex plate 4131. A first threaded hole 4125 is provided on the recessed platform 4121, and a first mounting hole 4132 is provided on the convex plate 4131. The first fixing plate 412 and the second fixing plate 413 can be connected by passing a bolt through the first mounting hole 4132 and screwing it into the first threaded hole 4125.

[0068] Specifically, in order to better ensure the flatness of the connection and surface of the entire fixed base 41 after connection, the first fixed plate 412 and the second fixed plate 413 are processed by wire cutting technology. That is, a whole plate is cut into two fixed plates, that is, a whole plate is cut to form the first fixed plate 412 and the second fixed plate 413. This ensures the fixed installation of the first fixed plate 412 and the second fixed plate 413 on the ground rail 1, while further ensuring the surface flatness of the top surface of the entire fixed base 41, thereby improving the wide applicability of the entire centering positioning mechanism 4.

[0069] Furthermore, such as Figure 1 , Figures 7 to 9As shown, both the bottom end of the first fixed plate 412 and the bottom end of the second fixed plate 413 are provided with opening grooves 4122 extending along the X-axis, and the two opening grooves 4122 form the aforementioned sliding groove 411. The outer dimensions of the two opening grooves 4122 correspond to each other, and along the Z-axis, the groove depth of the opening groove 4122 is the same as the thickness of the top plate 11 of the ground rail 1.

[0070] Specifically, such as Figure 1 and Figure 3 As shown, when installing the entire centering positioning mechanism 4 onto the ground rail 1, firstly, the opening slot 4122 of the first fixing plate 412 is inserted into the top plate 11 from one side of the ground rail 1 along the Y-axis. Then, the opening slot 4122 of the second fixing plate 413 is inserted into the top plate 11 from the other side of the ground rail 1 along the Y-axis. Finally, the protruding plate 4131 and the recessed platform 4121 are connected by bolts to form a fixed base 41 fixedly mounted on the ground rail 1, thus realizing the vertical positioning of the fixed base 41. The purpose of installing it on the ground rail 1 is as follows: When removing the entire centering positioning mechanism 4 from the ground rail 1, first unscrew the bolts so that the convex plate 4131 and the concave platform 4121 are no longer connected. Then, remove the opening slot 4122 of the first fixing plate 412 from one side of the top plate 11 of the ground rail 1 along the Y-axis. Then, remove the opening slot 4122 of the second fixing plate 413 from the other side of the top plate 11 of the ground rail 1 along the Y-axis. This will achieve the purpose of directly removing the fixing base 41 from the ground rail 1.

[0071] By setting a detachable first fixing plate 412 and a second fixing plate 413, the entire centering positioning mechanism 4 can be installed on or removed from the ground rail 1 at the corresponding position of the walking mechanism 2. It is not necessary to slide the fixing base 41 into or out of the ground rail 1 from the end of the longer ground rail 1 on the X-axis, which reduces the sliding path of the fixing base 41 along the X-axis on the ground rail 1, making the installation and removal of the fixing base 41 on the ground rail 1 simpler and more convenient, saving time and effort.

[0072] Furthermore, such as Figure 2 , Figures 6 to 9 As shown, support platforms 4123 are recessed downward along the Z-axis at the top of the first fixed plate 412 and the top of the second fixed plate 413, respectively. The two support platforms 4123 are arranged opposite to each other along the Y-axis. The support platforms 4123 are used to support the bracket 23 when the traveling wheel 21 and / or the guide mechanism 3 are removed, so as to provide a relatively stable support for the bracket 23.

[0073] By setting two support platforms 4123, after the traveling wheel 21 and / or guide mechanism 3 are disassembled, they can provide support for the bracket 23, preventing the bracket 23 from shifting. This prevents the bracket 23 from tilting due to unstable support during the entire maintenance process, ensuring the centering positioning effect of the bracket 23. Furthermore, since the bracket 23 is pressed against the two support platforms 4123 at this time, it provides a relatively stable clamping effect on the entire fixed base 41, thereby preventing the fixed base 41 and the entire centering positioning mechanism 4 from moving back and forth on the X-axis, and better ensuring the positional stability of the centering positioning mechanism 4 on the ground rail 1.

[0074] Specifically, such as Figure 1 and Figure 2 , Figures 5 to 8 As shown, an inclined surface 4124 is also provided on the first fixed plate 412. The inclined surface 4124 is located between the two support platforms 4123. That is, after the first fixed plate 412 and the second fixed plate 413 are connected, the inclined surface 4124 located between the two support platforms 4123 can provide an operable space to ensure that the inclined surface 4124 allows the traveling wheel 21 to pass through, so that the traveling wheel 21 can enter and exit the bracket 23 for assembly and disassembly. The width of the inclined surface 4124 on the Y-axis is equal to the thickness of the traveling wheel 21, so that the traveling wheel 21 can pass exactly through the inclined surface 4124.

[0075] Furthermore, such as Figure 1 , Figures 4 to 6 As shown, the positioning component 42 includes a first positioning member 421 and a second positioning member 422; wherein, one end of the first positioning member 421 is mounted on the top surface of the first fixed plate 412, and the other end of the first positioning member 421 extends along the X-axis to the traveling wheel 21, and the other end of the first positioning member 421 can be tightly attached to one side of the traveling wheel 21 along the Y-axis; one end of the second positioning member 422 is mounted on the top surface of the second fixed plate 413, and the other end of the second positioning member 422 extends along the X-axis to the traveling wheel 21, and the other end of the second positioning member 422 can be tightly attached to the other side of the traveling wheel 21 along the Y-axis.

[0076] By setting up a first positioning component 421 and a second positioning component 422 that work together, they can be closely attached to the opposite sides of the traveling wheel 21 along the Y-axis, which can effectively position the installation position of the traveling wheel 21 and / or the guide mechanism 3, improve the running straightness and assembly accuracy of the traveling wheel 21, and thus improve the running stability of the traveling mechanism 2 and the entire roadway stacker crane with centering positioning function.

[0077] Specifically, such as Figure 6 , Figure 10 and Figure 11As shown, the structures of the first positioning member 421 and the second positioning member 422 are the same; the first positioning member 421 includes a base 4211, a positioning plate 4212, and a reinforcing plate 4213; wherein, the base 4211 is connected to the top surface of the first fixing plate 412 and is located on the rear side of the support platform 4123, that is, the base 4211 will not block the support platform 4123, so as to avoid mutual interference between the base 4211 and the support platform 4123; the positioning plate 4212 is connected to the base On 4211, the positioning plate 4212 is used to closely adhere to the side of the traveling wheel 21 along the Y-axis, and the positioning plate 4212 of the first positioning member 421 and the positioning plate 4212 of the second positioning member 422 are parallel and opposite to each other along the Y-axis. The center line between the two positioning plates 4212 on the X-axis coincides with the center line of the ground rail 1. The reinforcing plate 4213 is connected between the base 4211 and the positioning plate 4212 so as to improve the structural strength of the entire first positioning member 421. Here, the specific shape and number of reinforcing plates 4213 are not limited; and the base 4211, the positioning plate 4212 and the reinforcing plate 4213 can be an integral structure.

[0078] Specifically, such as Figures 8 to 11 As shown, a second threaded hole 4126 is provided on the top surface of the first fixing plate 412 / second fixing plate 413, and a second mounting hole 4214 is provided on the base 4211. The base 4211 can be fixedly connected to the top surface of the first fixing plate 412 / second fixing plate 413 by passing a bolt through the second mounting hole 4214 and screwing it into the second threaded hole 4126.

[0079] Furthermore, such as Figure 1 , Figure 4 and Figure 6 As shown, the stop bar assembly includes a first stop bar 431 and a second stop bar 432; wherein, one end of the first stop bar 431 is connected to the base 4211 of the first positioning member 421, and the other end of the first stop bar 431 extends along the X-axis to the bracket 23, and the other end of the first stop bar 431 can be tightly attached to one side of the bracket 23 along the Y-axis; one end of the second stop bar 432 is connected to the base 4211 of the second positioning member 422, and the other end of the second stop bar 432 extends along the X-axis to the bracket 23, and the other end of the second stop bar 432 can be tightly attached to the other side of the bracket 23 along the Y-axis.

[0080] By setting up a first stop bar 431 and a second stop bar 432 that work together to fit tightly against the opposite sides of the bracket 23 along the Y-axis, the installation positions of the traveling wheel 21 and / or the guide mechanism 3 can be effectively positioned, improving the running straightness and assembly accuracy of the traveling wheel 21, and further improving the running stability of the traveling mechanism 2 and the entire roadway stacker crane with centering positioning function.

[0081] Specifically, such as Figure 6 and Figure 12 As shown, the structure of the first stop bar 431 is the same as that of the second stop bar 432. The first stop bar 431 includes a mounting plate 4311 and a baffle 4312. The mounting plate 4311 is connected to one side of the base 4211 of the first positioning member 421. The baffle 4312 is vertically connected to the mounting plate 4311 to form an L-shaped first stop bar 431. At least a portion of the baffle 4312 is placed on the top surface of the first fixing plate 412 and located on one side of the support platform 4123 to avoid the baffle 4312 from blocking the support platform 4123 and to ensure that there is no mutual interference between the baffle 4312 and the support platform 4123. The baffle 4312 is used to be tightly attached to the side of the bracket 23 along the Y-axis. The first stop bar 431 and the second stop bar 432 are symmetrically arranged with respect to the X-axis, that is, the first stop bar 431 and the second stop bar 432 form a square-like structure with respect to each other. The mounting plate 4311 and the baffle 4312 can be an integral structure, that is, the first baffle 431 and the second baffle 432 are both L-shaped steel plates.

[0082] Specifically, such as Figures 10 to 12 As shown, a third threaded hole 4215 is provided on one side of the base 4211, and a third mounting hole 4313 is provided on the mounting plate 4311. The mounting plate 4311 can be fixedly connected to the side of the base 4211 by passing a bolt through the third mounting hole 4313 and screwing it into the third threaded hole 4215.

[0083] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the bracket 23 includes a base frame 231 and side plates 232; wherein, the traveling wheel 21 is rotatably connected to the base frame 231 around the Y-axis; two side plates 232 protrude from opposite end faces of the base frame 231 along the X-axis, and the two side plates 232 located on the same end face are spaced apart along the Y-axis, and a support platform 4123 is used to support one side plate 232 to achieve the supporting function of the entire bracket 23; and the baffle 4312 of the first baffle 431 and the baffle 4312 of the second baffle 432 are respectively closely attached to the outer side surfaces of the two side plates 232 along the Y-axis to effectively position the installation position of the traveling wheel 21.

[0084] Specifically, such as Figure 1 and Figure 2As shown, the end face of the base frame 231 connected to the side plate 232 can abut against the baffle 4312 at the upper limit of the X-axis. That is, when the fixed base 41 is pushed to move linearly on the ground rail 1 along the X-axis, when the end of the baffle 4312 abuts against the end face of the base frame 231, it means that the fixed base 41 has moved to the preset position and can no longer move along the X-axis. The fixed base 41 at the preset position can better ensure that the positioning component 42 can better position and abut against the traveling wheel 21, and can better ensure that the baffle assembly can better position and abut against the bracket 23. In addition, when disassembling and maintaining the traveling wheel 21 and / or the guide mechanism 3, the operable space of the bracket 23 is guaranteed, while the positioning component 42 and the baffle assembly are kept within the bracket 23 with sufficient extension distance, and the load-bearing function of the two supports against the side plate 232 is not affected, thus improving the wide applicability of the entire aisle stacker crane with the centering positioning function.

[0085] The specific working process of the stacker crane with centering positioning function in this embodiment is as follows:

[0086] First, the first positioning member 421 is installed on the top surface of the first fixing plate 412, the second positioning member 422 is installed on the top surface of the second fixing plate 413, and the first stop bar 431 and the second stop bar 432 are respectively installed on the base 4211 of the first positioning member 421 and the base 4211 of the second positioning member 422, and the first stop bar 431 and the second stop bar 432 are installed symmetrically with respect to the X-axis.

[0087] Then, the opening slot 4122 of the first fixing plate 412 is placed directly on the top plate 11 of the ground rail 1 from one side, and the opening slot 4122 of the second fixing plate 413 is placed directly on the top plate 11 of the ground rail 1 from the other side, and the protruding plate 4131 is connected to the concave platform 4121 to fix the first fixing plate 412 and the second fixing plate 413. At this time, the sliding groove 411 formed by the two opening slots 4122 has the same size on the Z-axis as the thickness of the top plate 11 of the ground rail 1, so that the entire fixing base 41 will be constrained by the ground rail 1, ensuring that the fixing base 41 cannot move up and down along the Z-axis and cannot move left and right along the Y-axis.

[0088] Then, the entire centering positioning mechanism 4 is pushed along the X-axis in the direction of the traveling mechanism 2 until the ends of the baffle 4312 of the first stop bar 431 and the baffle 4312 of the second stop bar 432 contact the end face of the base frame 231. At this time, the support platform 4123 of the first fixing plate 412 and the support platform 4123 of the second fixing plate 413 extend along the X-axis to directly below the side plate 232 of the bracket 23, and the baffle 4312 of the first stop bar 431 and the baffle 4312 of the second stop bar 432 are respectively attached to the outer side of the two side plates 232 along the Y-axis, and the positioning plate 4212 of the first positioning member 421 and the positioning plate 4212 of the second positioning member 422 are respectively attached to the outer side of the traveling wheel 21 along the Y-axis.

[0089] Then, the traveling wheel 21 that needs to be repaired or replaced is removed. Specifically, the drive wheel axle 22 that is connected to the traveling wheel 21 is first removed directly from the side of the base frame 231 along the Y-axis, and then the traveling wheel 21 is removed from the base frame 231 along the X-axis from the inclined surface 4124. At this time, since the traveling wheel 21 has been removed from the bracket 23, the side plate 232 of the bracket 23 will press against the two support platforms 4123. After being subjected to the pressure, the support platforms 4123 provide support and positioning for the entire bracket 23, preventing the bracket 23 from tipping over due to excessive offset caused by the removal of the traveling wheel 21, thus improving maintenance safety. On the other hand, it can effectively press against the fixed base 41 to the ground rail 1, so as to prevent the centering positioning mechanism 4 from moving back and forth along the X-axis on the ground rail 1, thereby improving practicality.

[0090] Finally, when the traveling wheel 21 needs to be reinstalled after repair, first place the traveling wheel 21 into the base frame 231 along the inclined surface 4124, and install the drive wheel axle 22 along the Y-axis. At this time, because the bracket 23 is constrained by the installation of the two support platforms 4123 and the two baffles 4312, it always remains in the center position, so that the entire bracket 23 will not have any displacement along the Y-axis relative to the ground rail 1. At the same time, the traveling wheel 21 is constrained by the installation of the first positioning component 421 and the second positioning component 422, and always remains in the center position, and will not have any displacement along the Y-axis. This achieves the effect of quick repair and replacement of the traveling mechanism 2 and centering and positioning adjustment. At this time, the center line between the two positioning plates 4212 on the X-axis coincides with the center line of the ground rail 1.

[0091] In this embodiment, the stacker crane with centering positioning function is equipped with a centering positioning mechanism 4 for the centering positioning walking mechanism 2. The fixed base 41 is designed according to the outer dimensions of the ground rail 1, so that the fixed base 41 can be directly and quickly installed and fixed on the ground rail 1. The positioning plate 4212 and the baffle 4312 are designed according to the outer dimensions of the walking wheel 21 and the bracket 23, so as to limit and constrain the installation position of the walking wheel 21 and the bracket 23, thereby improving the centering positioning accuracy of the walking mechanism 2 and ensuring the operational stability of the entire stacker crane with centering positioning function.
