Description

Technical Field

[0001] This utility model relates to the field of tunnel stacker technology, and in particular to a device for disassembling and assembling the traveling wheel assembly and a tunnel stacker. Background Technology

[0002] In a stacker crane operating in aisle lanes, the traveling mechanism is the core component. It moves linearly along a ground rail via a pair of traveling wheel assemblies. A guiding mechanism is needed to guide the traveling mechanism's movement on the ground rails, ensuring its straightness and accuracy. However, due to the heavy load on the traveling wheel assemblies and the relative friction between the guiding mechanism and the ground rails, the traveling wheel assemblies and guiding mechanism are prone to damage and wear during prolonged operation. Therefore, it is necessary to stop the machine for disassembly, maintenance, and replacement of the traveling wheel assemblies and guiding mechanism to ensure the overall operational stability of the stacker crane.

[0003] In particular, considering that the wheel axle and the wheel of the traveling wheel assembly have a conical fit, and the precision requirements of this conical fit are high, directly striking the wheel axle to disassemble the traveling wheel assembly can easily damage the conical fit between the wheel axle and the wheel. In addition, during long-term use, the bearing sleeve and bearing of the traveling wheel assembly are usually damaged. If the wheel axle is directly disassembled by the threaded movement of the screw, it is time-consuming and laborious, resulting in low maintenance efficiency. It can also easily damage the threaded hole on the wheel axle that is used for threaded connection with the screw, thus easily damaging the wheel axle.

[0004] To address the above problems, there is an urgent need for a device for disassembling and assembling the traveling wheel assembly and a stacker crane for roadways. Utility Model Content

[0014] A flange ring is provided parallel to and spaced from the fixed ring along the Y-axis, and the flange ring is installed on one side of the bracket;

[0015] An extension column is attached to the outer ring of the fixed ring at one end and to the flange ring at the other end along the Y-axis. The connection position of the extension column on the outer ring of the fixed ring is adjustable to adjust the distance between the fixed ring and the flange ring. The screw passes through the fixed ring and the flange ring sequentially along the Y-axis to be threadedly connected to the wheel axle.

[0016] As an optional solution, the extended column includes:

[0017] The slide bar has a third threaded hole at one end near the flange ring, and the shank of the first screw passes through the flange ring and is screwed into the third threaded hole;

[0018] A threaded rod is coaxially connected to one end of the slide rod. The outer diameter of the threaded rod is smaller than that of the slide rod. The threaded rod passes through the outer ring of the fixing ring. Adjusting nuts are respectively pressed against the opposite sides of the outer ring of the fixing ring. The adjusting nuts are threaded onto the threaded rod. By turning the position of the adjusting nuts on the threaded rod, the distance between the fixing ring and the flange ring can be adjusted.

[0019] As an optional solution, multiple extension columns are provided, and the multiple extension columns are arranged at intervals along the circumference of the flange ring, with the screw placed at the center of each extension column.

[0020] As an optional feature, the bracket has a retaining ring protruding from its side, and the flange ring can be fitted onto the retaining ring.

[0021] As an optional solution, the inner and outer rings of the fixing ring are provided with multiple weight-reducing holes, and the center of the inner ring of the fixing ring is provided with a through hole for the screw to pass through.

[0022] As an optional solution, the wheel assembly disassembly and assembly device further includes an auxiliary component, which is disposed on both sides of the bracket opposite to the disassembly and assembly along the Y-axis; the auxiliary component includes:

[0023] The L-shaped bracket includes a long rod and a short rod connected vertically, the long rod being mounted on the bracket and the short rod extending along the Y-axis to a narrow plate that contacts the ground rail;

[0024] A support jack is placed on the ground. The connection between the long rod and the short rod is located on the support jack. The support jack is used to lift the L-shaped bracket upward along the Z-axis to lift the traveling wheel and disengage it from the ground rail.

[0029] A guiding mechanism is provided between the ground rail and the bracket to guide the movement of the traveling wheel assembly on the X-axis.

[0031] By mounting the mounting frame to one side of the bracket, the hollow jack is connected to the mounting frame, and one end of the screw is connected to the hollow jack, while the other end of the screw is threaded to the axle. When it is necessary to disassemble the wheel assembly, the hollow jack drives the screw to push the axle along the Y-axis, providing a large instantaneous pushing force to the axle. Furthermore, since the hollow jack is positioned to correspond to the conical fit between the wheel and the axle, the axle can be quickly pushed out of the bracket relative to the conical fit structure along the Y-axis. In other words, the above-mentioned method of using the threaded connection between the screw and the axle, and applying axial force to the screw with the hollow jack, ensures that the conical fit structure between the axle and the wheel is not damaged, and that the axle is not damaged, while providing maximum axial force to the axle. This allows for quick and easy removal of the axle, thereby improving maintenance efficiency. Attached Figure Description

[0050] 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.

[0051] 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.

[0052] 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.

[0053] This embodiment proposes a wheel assembly disassembly and assembly device and a roadway stacker including the wheel assembly disassembly and assembly device, such as Figures 1 to 3As shown, the stacker crane also includes a ground rail 10, a traveling mechanism 20, and a guiding mechanism 30. The ground rail 10 is fixedly installed and extends along the X-axis. The ground rail 10 has an I-shaped structure, comprising a base plate 101, a narrow plate 102, and a top plate 103. The narrow plate 102 connects the base plate 101 and the top plate 103 to form an I-shaped structure. The base plate 101 is fixedly installed on the ground. The traveling mechanism 20 includes a bracket 201 and two traveling wheel assemblies 202. Both traveling wheel assemblies 202 can travel along the X-axis on the ground rail 10, driving the entire traveling mechanism 20 to travel along the X-axis on the ground rail 10. The two traveling wheel assemblies 202 are spaced apart within the bracket 201 along the X-axis. The guiding mechanism 30 is located between the ground rail 10 and the bracket 201, guiding the traveling wheel assemblies 202 to travel linearly along the X-axis.

[0054] It is worth noting that the main improvement in this embodiment is in the disassembly and assembly device of the walking wheel assembly. Therefore, the specific working principle of the walking mechanism 20 and the guiding mechanism 30 will not be described in detail here. You can refer to the stacker crane in the prior art. In addition, the guiding mechanism 30 can adopt the common guiding structure in the prior art. Here, the specific structure of the guiding mechanism 30 will not be described in detail.

[0055] Specifically, such as Figure 4 As shown, the traveling wheel assembly 202 includes an axle 2022, a traveling wheel 2021 sequentially mounted on the axle 2022, a bearing sleeve 2024, a bearing 2023, a washer 2025, and a retaining ring 2026. The traveling wheel 2021 has a bearing sleeve 2024, a bearing 2023, a washer 2025, and a retaining ring 2026 on opposite sides along the Y-axis. The traveling wheel 2021 and the axle 2022 have a tapered fit. The traveling wheel 2021 is placed in a groove in the bracket 201. The traveling wheel 2021 provides load-bearing and driving functions for the entire traveling mechanism 20. The axle 2022... The disassembly and assembly direction of bearing 2022 can only be along the Y-axis. The inner ring of bearing sleeve 2024 mates with axle 2022. One end face of bearing sleeve 2024 contacts the wheel 2021, and the other end face contacts bearing 2023, providing a mounting position for bearing 2023. Furthermore, the inner diameter of bearing 2023 is the same as the diameter of axle 2022, and the outer diameter of bearing 2023 is the same as the diameter of the mounting hole on bracket 201, providing positioning and support for axle 2022. Shim 2025 and retaining ring 2026 provide an axial mounting position for bearing 2023. When disassembling the wheel assembly 202, first remove retaining ring 2026 and shim 2025, then push axle 2022 out along the Y-axis, then remove bearing 2023 and bearing sleeve 2024 in sequence, and finally remove wheel 2021 from the slot in bracket 201 along the X-axis. Among them, bearing sleeve 2024 is an aluminum sleeve.

[0056] Furthermore, such as Figures 1 to 3 , Figure 5 and Figure 6 As shown, the wheel assembly disassembly and assembly device includes a disassembly and assembly component 1, which includes a mounting frame 11, a hollow jack 12, and a screw 13. The mounting frame 11 is mounted on one side of the bracket 201. The hollow jack 12 extends along the Y-axis and is connected to the mounting frame 11. The orientation of the hollow jack 12 corresponds to the conical surface fit between the wheel 2021 and the axle 2022. One end of the screw 13 is connected to the hollow jack 12, and the other end of the screw 13 is threaded to the axle 2022. The hollow jack 12 can drive the screw 13 to push the axle 2022 along the Y-axis, so as to push the axle 2022 out of the bracket 201 along the Y-axis.

[0057] Compared to existing technologies, the wheel assembly disassembly and assembly device in this embodiment changes the disassembly method of the wheel axle 2022. By mounting the mounting frame 11 on one side of the bracket 201, the hollow jack 12 is connected to the mounting frame 11, and one end of the screw 13 is connected to the hollow jack 12, while the other end of the screw 13 is threaded to the wheel axle 2022. When the wheel assembly 202 needs to be disassembled, the hollow jack 12 drives the screw 13 to push the wheel axle 2022 along the Y-axis, providing a large instantaneous pushing force to the wheel axle 2022. Furthermore, the orientation of the hollow jack 12 corresponds to the conical surface fit between the wheel 2021 and the wheel axle 2022. The wheel axle 2022 can be quickly pushed out from the bracket 201 along the Y-axis relative to the conical mating structure. That is, the above-mentioned method of using the threaded connection between the screw 13 and the wheel axle 2022 and using the hollow jack 12 to apply axial force to the screw 13 can ensure that the conical mating structure between the wheel axle 2022 and the traveling wheel 2021 is not damaged, and the wheel axle 2022 is not damaged, so as to provide the maximum axial force to the wheel axle 2022. This allows the wheel axle 2022 to be removed quickly and easily, thereby improving maintenance efficiency and improving the maintenance accuracy of the traveling wheel assembly 202, and thus improving the overall stability of the stacker crane operation in the alleyway.

[0058] The following is a detailed description of component 1 for disassembly and assembly:

[0059] Furthermore, such as Figure 7As shown, a first threaded hole 2027 and a second threaded hole 2028 are respectively provided at opposite ends of the wheel axle 2022. The screw 13 can be concentrically connected to the first threaded hole 2027 or the second threaded hole 2028 along the Y-axis to achieve a fixed connection between the screw 13 and the wheel axle 2022. The length of the first threaded hole 2027 and the length of the second threaded hole 2028 can be the same or different. Furthermore, according to the specific conical surface fit structure between the traveling wheel 2021 and the wheel axle 2022, the screw 13 is correspondingly connected to the first threaded hole 2027 or the second threaded hole 2028, so that the wheel axle 2022 and the traveling wheel 2021 can be quickly and without damage under the pushing action of the screw 13.

[0060] Specifically, such as Figure 1 , Figure 5 , Figures 6 to 8 As shown, the mounting frame 11 includes a fixing ring 111, a flange ring 112, and an extension column 113; one end of the hollow jack 12 is connected to the inner ring of the fixing ring 111; the flange ring 112 is parallel to and spaced from the fixing ring 111 along the Y-axis, and is mounted on one side of the bracket 201; one end of the extension column 113 is connected to the outer ring of the fixing ring 111, and the other end of the extension column 113 is connected to the flange ring 112 along the Y-axis. The connection position of the extension column 113 on the outer ring of the fixing ring 111 is adjustable to adjust the distance between the fixing ring 111 and the flange ring 112. The screw 13 passes through the fixing ring 111 and the flange ring 112 in sequence along the Y-axis to be threadedly connected to the wheel axle 2022.

[0061] By setting up a fixed ring 111, flange ring 112 and extension column 113 that are connected to each other, the structure of the entire mounting frame 11 is simpler and more aesthetically pleasing than setting the mounting frame 11 as a whole cylinder. It also reduces the weight of the entire mounting frame 11, so that the entire wheel assembly disassembly and assembly device can be quickly and easily installed onto the bracket 201, saving time and effort. At the same time, it can provide space for the hollow jack 12 and screw 13 to be assembled and operated.

[0062] Furthermore, by making the connection position of the extension column 113 on the outer ring of the fixing ring 111 adjustable, the distance between the fixing ring 111 and the flange ring 112 can be adjusted, thereby adjusting the length of the screw 13 extending out of the flange ring 112 along the Y-axis. This allows the extension length of the screw 13 to be more matched with the length of the wheel axle 2022, thus enabling the screw 13 to be adapted to connect with various wheel axles 2022 of different lengths, thereby improving the versatility and applicability of the entire wheel assembly disassembly and assembly device.

[0063] Furthermore, such as Figures 5 to 10As shown, the extended column 113 includes a slide rod 1131 and a threaded rod 1132. The slide rod 1131 has a third threaded hole 1135 at one end near the flange ring 112. The shank of the first screw 1134 passes through the first hole 1121 of the flange ring 112 and is threaded into the third threaded hole 1135 to achieve the connection between the extended column 113 and the flange ring 112. The threaded rod 1132 is coaxially connected to one end of the slide rod 1131. The outer diameter of the threaded rod 1132 is smaller than the outer diameter of the slide rod 1131 to form a stepped shaft structure. The threaded rod 1132 passes through the second hole 1113 of the outer ring of the fixing ring 111. Adjusting nuts 1133 are respectively pressed against the opposite sides of the outer ring of the fixing ring 111. The adjusting nuts 1133 are threaded onto the threaded rod 1132 so that the distance between the fixing ring 111 and the flange ring 112 can be adjusted by turning the position of the adjusting nuts 1133 on the threaded rod 1132.

[0064] Specifically, such as Figure 5 As shown, the size of the threaded rod 1132 corresponds to the size of the second hole 1113 on the fixed ring 111. After the threaded rod 1132 passes through the second hole 1113, the threaded rod 1132 can be fixedly connected to the fixed ring 111 on opposite sides of the outer ring of the fixed ring 111 by adjusting nuts 1133. That is, the extension column 113 is a bridge connecting the fixed ring 111 and the flange ring 112. On the one hand, the extension column 113 can provide an installation position and support point for the fixed ring 111 and the hollow jack 12. On the other hand, it can reserve operable maintenance space for disassembling and assembling the wheel axle 2022.

[0065] Specifically, such as Figure 5 , Figure 6 and Figure 9 As shown, four third holes 1114 are provided at equal angles on the inner ring of the fixing ring 111. The size of the third hole 1114 corresponds to the size of the fourth threaded hole on the end face of the hollow jack 12. The second screw 1115 can be passed through the third hole 1114 and screwed into the fourth threaded hole of the hollow jack 12 to fix the fixing ring 111 and the hollow jack 12 together.

[0066] Furthermore, such as Figure 5 and Figure 6As shown, multiple extension columns 113 are provided, arranged at intervals along the circumference of the flange ring 112. The screw 13 is positioned at the center of each extension column 113 to avoid interference between the screw 13 and the extension column 113. The extension columns 113 better ensure the stability and reliability of the connection between the fixing ring 111 and the flange ring 112, and improve the support strength and structural stability of the entire mounting frame 11. In this embodiment, four extension columns 113 are provided; however, the specific number of extension columns 113 is not limited.

[0067] Specifically, such as Figures 1 to 3 , Figure 11 As shown, a retaining ring 2011 protrudes from the side of the bracket 201, and the flange ring 112 can be fitted onto the retaining ring 2011 to install the mounting frame 11 onto the side of the bracket 201. On the one hand, the snap-fit ​​method makes the connection between the flange ring 112 and the bracket 201 simple and convenient, so as to facilitate quick disassembly and installation. On the other hand, it can ensure the stability of the connection between the flange ring 112 and the bracket 201 and prevent the entire mounting frame 11 from falling off the bracket 201.

[0068] Furthermore, such as Figure 5 and Figure 9 As shown, multiple weight-reducing holes 1111 are provided between the inner and outer rings of the fixing ring 111, and a through hole 1112 is provided at the center of the inner ring of the fixing ring 111 for the screw 13 to pass through. That is, the screw 13 passes through the hollow jack 12, and the end of the screw 13 abuts against the end face of the hollow jack 12. The rod of the screw 13 passes through the hollow jack 12, the through hole 1112 and the flange ring 112 in sequence along the Y-axis, and is connected to the first threaded hole 2027 or the second threaded hole 2028 of the wheel axle 2022.

[0069] By setting multiple weight-reducing holes 1111 and hollow jacks 12, the weight of the entire mounting frame 11 can be reduced more effectively, so that the entire wheel assembly disassembly and assembly device can be quickly and easily installed onto the bracket 201, saving more time and effort.

[0070] The following is a detailed description of auxiliary component 2:

[0071] Furthermore, such as Figures 1 to 3 , Figures 12 to 14As shown, the wheel assembly disassembly and assembly device also includes an auxiliary component 2, which is positioned opposite to the disassembly and assembly component 1 along the Y-axis on both sides of the bracket 201. The auxiliary component 2 includes an L-shaped bracket 21 and a support jack 22. The L-shaped bracket 21 includes a long rod 211 and a short rod 212 connected vertically. The long rod 211 is mounted on the bracket 201, and the short rod 212 extends along the Y-axis to the narrow plate 102 that contacts the ground rail 10. The support jack 22 is placed on the ground, and the connection between the long rod 211 and the short rod 212 is located on the support jack 22. The support jack 22 is used to lift the L-shaped bracket 21 upward along the Z-axis to lift the wheel 2021 and disengage it from the ground rail 10, thereby facilitating the screw 13 to push out the wheel axle 2022 along the Y-axis. The long rod 211 and the short rod 212 can be a single integrated structure, and the L-shaped bracket 21 is made of cast iron.

[0072] By setting up a coordinated L-shaped bracket 21 and a support jack 22, and positioning the auxiliary component 2 and the disassembly / assembly component 1 opposite each other along the Y-axis on both sides of the bracket 201, a balancing force opposite to the thrust of the screw 13 can be applied to the bracket 201 during the disassembly / assembly of the traveling wheel assembly 202. This balancing force ensures that the bracket 201 does not tilt or even tip over, thus avoiding the safety hazard of tipping over due to excessive offset of the entire traveling mechanism 20 caused by excessive thrust of the hollow jack 12. This fundamentally solves the safety risks of the traveling wheel assembly 202 during disassembly / assembly and maintenance, and better achieves the goal of improving the overall stability of the stacker crane in the alleyway.

[0073] Specifically, by making the short rod 212 contact the narrow plate 102 of the ground rail 10, the phenomenon of the walking mechanism 20 shifting due to excessive force of the hollow jack 12 during the disassembly and assembly of the walking wheel assembly 202 can be effectively prevented; and by placing the support jack 22 directly below the L-shaped bracket 21, the lifting force of the support jack 22 can directly lift the walking wheel assembly 202 and the bracket 201 as a whole upward along the Z-axis, so that the walking wheel 2021 is separated from the top plate 103 of the ground rail 10.

[0074] Specifically, such as Figures 11 to 13 As shown, a fourth hole 2111 is provided on the long rod 211. The fourth hole 2111 cooperates with the fifth hole 2012 on the bracket 201 so that the long rod 211 and the bracket 201 can be fixedly connected by bolts and fastening nuts.

[0075] Furthermore, such as Figures 1 to 3 , Figure 12 and Figure 13As shown, a first nylon block 2121 is provided on the side of the short rod 212 near the narrow plate 102, and the first nylon block 2121 abuts against the narrow plate 102. On the one hand, the first nylon block 2121 can better prevent the bracket 201 from tipping over, so as to better avoid the safety hazard caused by excessive displacement of the bracket 201 when pushing the wheel axle 2022 along the Y axis. On the other hand, the first nylon block 2121 can provide better buffer protection for the L-shaped bracket 21 and the ground rail 10, thereby improving the service life of the L-shaped bracket 21 and the ground rail 10.

[0076] Specifically, such as Figures 1 to 3 , Figure 12 and Figure 13 As shown, the top surface of the short rod 212 near the top plate 103 of the ground rail 10 is provided with a second nylon block 2122, and there is a gap between the second nylon block 2122 and the bottom surface of the top plate 103. On the one hand, the second nylon block 2122 can better prevent the bracket 201 from tipping over, and further avoid the safety hazard caused by excessive displacement of the bracket 201 when pushing the wheel axle 2022 along the Y axis. On the other hand, the second nylon block 2122 can provide better buffer protection for the L-shaped bracket 21 and the ground rail 10, thereby further improving the service life of the L-shaped bracket 21 and the ground rail 10. In addition, since there is a gap between the second nylon block 2122 and the bottom surface of the top plate 103, it can provide the bracket 201 with upward lifting space along the Z axis, ensuring that the support jack 22 can smoothly lift the entire walking mechanism 20.

[0077] In other words, to prevent the excessive force between the L-shaped bracket 21 and the ground rail 10 caused by the excessive lifting force of the hollow jack 12 on the screw 13, which would lead to damage and deformation of the L-shaped bracket 21 and wear of the ground rail 10, the first nylon block 2121 and the second nylon block 2122 are designed to prevent shock. That is, the buffering effect of the first nylon block 2121 and the second nylon block 2122 can effectively extend the service life of the L-shaped bracket 21 and the ground rail 10, thereby improving the durability of the entire wheel assembly disassembly and assembly device.

[0078] And, as Figures 1 to 3 , Figure 12As shown, the support jack 22 can directly contact and lift the L-shaped bracket 21 to periodically lift the bracket 201, facilitating the disassembly and maintenance of the traveling wheel assembly 202. Compared to directly contacting and lifting the bracket 201 with the support jack 22, the L-shaped bracket 21 provides a more suitable support point for the support jack 22 and ensures a larger contact support area. This effectively solves the problem of slippage and bracket 201 lifting caused by the small lower contact surface area of ​​the bracket 201 and the close proximity of the bracket 201 to the ground rail 10 when the support jack 22 directly releases and lifts the bracket 201. This further avoids the safety risk of the traveling mechanism 20 tilting and ensures the accuracy and reliability of lifting the bracket 201, thereby improving the safety and practicality of the entire traveling wheel assembly disassembly and assembly device.

[0079] Furthermore, such as Figure 3 and Figure 12 As shown, after the L-shaped bracket 21 is installed onto the bracket 201, the gap between the second nylon block 2122 and the bottom surface of the top plate 103 is 5mm. On the one hand, this ensures that the traveling wheel assembly 202 is lifted upward along the Z-axis and disengaged from the ground rail 10. On the other hand, it limits the lifting distance of the bracket 201 along the Z-axis, preventing the safety risk of the traveling mechanism 20 tilting due to the excessive lifting distance of the bracket 201 along the Z-axis, and further improving the safety of the entire traveling wheel assembly disassembly and assembly device.

[0080] The specific working process of the wheel assembly disassembly and assembly device in this embodiment is as follows:

[0081] When it is necessary to remove the travel wheel assembly 202;

[0082] First, remove the retaining rings 2026 and washers 2025 from the bracket 201 on both sides of the traveling wheel 2021. Then, use the second screw 1115 to pass through the third hole 1114 on the fixing ring 111 and screw it into the fourth threaded hole of the hollow jack 12 to fix the fixing ring 111 and the hollow jack 12. Then, use the shank of the first screw 1134 to pass through the first hole 1121 of the flange ring 112 and screw it into the third threaded hole 1135 of the extension rod 211 to fix the extension rod 113 and the flange ring 112. At the same time, the threaded rod 1132 passes through the second hole 1113 of the outer ring of the fixing ring 111 and, according to the specific length of the wheel axle 2022, tighten the adjusting nuts 1133 on the opposite sides of the outer ring of the fixing ring 111 to fix the extension rod 211 and the fixing ring 111, and ensure that the distance between the fixing ring 111 and the flange ring 112 matches the length of the wheel axle 2022.

[0083] Next, the flange ring 112 is pushed in axially to directly clamp onto the retaining ring 2011 of the bracket 201, thus fixing the flange ring 112 to the side of the bracket 201. Then, the screw 13 is passed sequentially along the Y-axis through the hollow jack 12, the through hole 1112 of the fixing ring 111, and the flange ring 112, and threadedly connected to the first threaded hole 2027 or the second threaded hole 2028 of the wheel axle 2022. At this time, the connection direction of the screw 13 corresponds to the tapered surface fit between the traveling wheel 2021 and the wheel axle 2022, so as to facilitate easier and faster subsequent ejection of the wheel axle 2022.

[0084] Then, the long rod 211 is fixedly connected to the bracket 201 with bolts and fastening nuts, and the support jack 22 is adjusted to the minimum stroke and placed directly below the L-shaped bracket 21. That is, at this time, the L-shaped bracket is placed directly on the support jack 22. Then, the support jack 22 is used to lift the bracket 201 upward along the Z-axis until the traveling wheel 2021 is completely removed from the ground rail 10.

[0085] Finally, the lifting force of the hollow jack 12 is used to push the screw 13 to push the wheel axle 2022 out of the bracket 201 along the Y-axis to disassemble the wheel axle 2022. Then, the bearings 2023 and bearing sleeves 2024 located on opposite sides of the traveling wheel 2021 are disassembled. The traveling wheel 2021 is then taken out of the bracket 201 along the X-axis to disassemble the entire traveling wheel assembly 202.

[0086] When it is necessary to reassemble the wheel assembly 202 to the bracket 201:

[0087] First, the second screw 1115 is passed through the third hole 1114 on the retaining ring 111 and screwed into the fourth threaded hole of the hollow jack 12 to fix the retaining ring 111 and the hollow jack 12. Then, the shank of the first screw 1134 is passed through the first hole 1121 of the flange ring 112 and screwed into the third threaded hole 1135 of the extension rod 211 to fix the extension rod 113 and the flange ring 112. At the same time, the threaded rod 1132 passes through the second hole 1113 of the outer ring of the retaining ring 111, and the adjusting nut 1133 is pressed against the opposite sides of the outer ring of the retaining ring 111 according to the specific length of the wheel axle 2022 to fix the extension rod 211 and the retaining ring 111, and to ensure that the distance between the retaining ring 111 and the flange ring 112 matches the length of the wheel axle 2022.

[0088] Then, the flange ring 112 is pushed in axially to directly clamp onto the retaining ring 2011 of the bracket 201, thereby fixing the flange ring 112 to the side of the bracket 201. Next, the screw 13 is passed sequentially along the Y-axis through the hollow jack 12, the through hole 1112 of the fixing ring 111, and the flange ring 112, and threadedly connected to the first threaded hole 2027 or the second threaded hole 2028 of the wheel axle 2022. At this point, the connection direction of the screw 13 corresponds to the tapered surface fit between the traveling wheel 2021 and the wheel axle 2022, facilitating easier and faster subsequent ejection of the wheel axle 2022.

[0089] Then, the long rod 211 is fixedly connected to the bracket 201 with bolts and fastening nuts, and the support jack 22 is adjusted to the minimum stroke and placed directly below the L-shaped bracket 21. That is, at this time, the L-shaped bracket is placed directly on the support jack 22. Then, the support jack 22 is used to lift the bracket 201 upward along the Z-axis until the traveling wheel 2021 is completely removed from the ground rail 10.

[0090] Finally, place the traveling wheel 2021 back into the slot of the bracket 201 along the X-axis, and lift the bracket 201 upward along the Z-axis with the support jack 22 until the holes on opposite sides of the bracket 201 are concentric with the holes of the traveling wheel 2021. Then, use the lifting force of the hollow jack 12 to push the wheel axle 2022 along the Y-axis to completely lock the traveling wheel 2021 and the wheel axle 2022 with a tapered surface. Reinstall the bearing 2023 and bearing sleeve 2024. Then, install the shims 2025 and retaining rings 2026 on opposite sides of the traveling wheel 2021 to complete the reinstallation of the entire traveling wheel assembly 202.

[0091] In this embodiment, the wheel assembly disassembly and assembly device includes a disassembly and assembly component 1, which effectively improves the maintenance efficiency and accuracy of the wheel assembly 202, taking into account the external dimensions of the wheel 2021 and its fit with the axle 2022. Furthermore, to address the safety hazard of the walking mechanism 20 tipping over due to excessive pushing deviation of the hollow jack 12 during disassembly and assembly, an auxiliary component 2 is provided. This fundamentally solves the safety risks during the maintenance of the wheel assembly 202, thereby improving the overall operational stability of the stacker crane in the tunnel.
