Description

Technical Field

[0001] This utility model relates to the field of tunnel stacker technology, and in particular to a walking motor disassembly and assembly device 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 on a ground rail via a pair of traveling wheel assemblies. The traveling motor is the drive structure that rotates the drive wheel shaft in the traveling wheel assembly, enabling the traveling mechanism to move linearly on the ground rail. Due to the heavy load-bearing capacity of the traveling wheel assembly, it is prone to damage and wear during long-term operation of the stacker crane. Therefore, it is necessary to stop the machine to disassemble, maintain, and replace the traveling wheel assembly to ensure the operational stability of the entire stacker crane.

[0003] When disassembling and replacing the traveling wheel assembly, the traveling motor connected to the drive wheel axle must first be removed. However, due to the heavy weight of the traveling motor, manual disassembly and assembly is prone to low efficiency, time-consuming, labor-intensive, and costly. Furthermore, manual disassembly and assembly can easily damage the mating surfaces between the drive wheel axle and the traveling motor, greatly affecting the maintenance efficiency of the entire stacker crane in the aisle. Moreover, because the traveling motor is close to the ground and the space where it is located is relatively small, hoisting equipment cannot enter the maintenance site to hoist the traveling motor, further increasing the difficulty of disassembling and assembling the traveling motor.

[0004] To address the above problems, there is an urgent need for a walking motor disassembly and assembly device and a roadway stacker crane. Utility Model Content

[0005] The purpose of this utility model is to propose a walking motor disassembly and assembly device and a roadway stacker, which can protect the mating surface between the drive wheel axle and the walking motor during disassembly and installation, improve the maintenance efficiency and accuracy of the entire roadway stacker, and reduce the difficulty of disassembling and assembling the walking motor.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A travel motor disassembly and assembly device, the travel mechanism including a bracket, a travel wheel assembly and a travel motor, the travel wheel assembly being disposed within the bracket, the travel wheel assembly including a drive wheel axle and a travel wheel sleeved on the drive wheel axle, the drive wheel axle passing through the travel motor along its axial direction, the travel motor being mounted on one outer side of the bracket; the travel motor disassembly and assembly device includes:

[0008] The disassembly assembly has one end threadedly connected to the walking motor, and the other end can move along a first direction to abut against the drive wheel shaft. Twisting the disassembly assembly can drive the walking motor to move off the drive wheel shaft along a second direction. The first direction and the second direction are opposite and both are parallel to the axial direction of the drive wheel shaft.

[0009] The mounting component has one end threadedly connected to the drive wheel shaft. Tightening the other end of the mounting component allows it to move along the first direction to a side of the walking motor that pushes against it, thereby moving the walking motor along the first direction to a mounting position on the outer side of the bracket.

[0010] The lifting assembly can be selectively moved below the travel motor to support the travel motor during disassembly and installation.

[0011] As an optional solution, the disassembly assembly includes:

[0012] Fixed base;

[0013] A connecting bolt passes through the fixed base along the first direction and is threaded to the walking motor;

[0014] A push rod is threaded through the fixed seat along the first direction;

[0015] The limiting member is coaxially connected to the end of the push rod that extends out of the fixed seat along the first direction. The limiting member is used to press against the drive wheel shaft along the first direction. Rotating the push rod around the axial direction of the drive wheel shaft can drive the fixed seat to move along the push rod along the second direction, so as to drive the walking motor to move off the drive wheel shaft along the second direction.

[0016] As an optional solution, multiple connecting bolts are provided, and the multiple connecting bolts are evenly arranged along the circumference of the fixed seat, with the top rod located in the middle of each connecting bolt; and the outer circumferential surface of the connecting bolt is provided with an annular step, and when the connecting bolt is screwed to the travel motor, the annular step can limit and abut against the outer side of the travel motor.

[0017] As an optional solution, the end of the top rod facing the walking motor is an unthreaded cylindrical rod; the limiting member includes:

[0018] The assembly includes an abutment block, a first bearing, and a cover. The outer ring of the first bearing is installed inside the abutment block, and the cylindrical rod passing through the fixed seat is inserted into the inner ring of the first bearing. The cover is placed on one end of the abutment block.

[0019] As an optional solution, the end of the abutment block away from the cover is coaxially provided with a first hole. The diameter of the first hole is smaller than the outer diameter of the first bearing and larger than the outer diameter of the push rod. The end of the abutment block facing the cover is coaxially provided with a second hole. The second hole communicates with the first hole. The diameter of the second hole is the same as the outer diameter of the first bearing, so that the first bearing can be installed in the abutment block along the second hole. A retaining ring is installed on the side of the second hole near the cover, so that the retaining ring limits and fixes the first bearing in the second hole. The inner diameter of the first bearing is the same as the outer diameter of the cylindrical rod.

[0020] As an optional solution, the disassembly assembly further includes:

[0021] A vertical rod is perpendicularly connected to the top rod. The end of the top rod that is not connected to the fixed base is placed in the middle of the vertical rod. Rotating the vertical rod can drive the top rod to rotate axially around the drive wheel shaft.

[0022] As an optional solution, the installation components include:

[0023] A pull rod, one end of which is threaded through the drive wheel shaft in the second direction;

[0024] The assembly includes a nut, a second bearing, and a pressure block. The nut is threaded onto one end of the pull rod that extends beyond the drive wheel shaft. The second bearing is located between the pressure block and the nut. A cylindrical platform is provided at one end of the nut near the second bearing. The outer diameter of the cylindrical platform is the same as the inner diameter of the second bearing, allowing the cylindrical platform to be inserted into the inner ring of the second bearing. The pull rod passes sequentially through the pressure block, the inner ring of the second bearing, and the nut. The nut is rotated axially around the drive wheel shaft, allowing it to push the travel motor to the mounting position along the first direction on the pull rod.

[0025] As an optional solution, the pressure block includes:

[0026] A first ring and a second ring, the second ring being connected to the side of the first ring near the second bearing. The outer diameter of the first ring is larger than the outer diameter of the second ring, and the inner diameter of the first ring is larger than the diameter of the drive wheel shaft, so that the pressure block does not contact the drive wheel shaft. The inner diameter of the second ring matches the outer diameter of the second bearing, so that the second bearing fits against one side of the second ring, and the inner diameter of the second ring is larger than the diameter of the pull rod.

[0027] As an optional solution, the lifting assembly includes:

[0028] Hydraulic module;

[0029] A support plate is provided, and a hydraulic module is connected to one side of the support plate. The hydraulic module is used to drive the support plate to move along the Z-axis so that the support plate is positioned below the walking motor.

[0030] Aisle stacker cranes, including:

[0031] A fixed ground rail extends along the X-axis;

[0032] The walking mechanism has a walking wheel assembly that can travel along the X-axis on the ground rail, and the walking motor of the walking mechanism can be disassembled and installed based on the walking motor disassembly and assembly device described above.

[0033] The beneficial effects of this utility model are as follows:

[0034] By threading one end of the disassembly assembly to the travel motor to securely connect the disassembly assembly and the travel motor, the other end of the disassembly assembly can move along a first direction to abut against the drive shaft. Tightening the disassembly assembly allows the travel motor to be moved off the drive shaft along a second direction while still abutting against the drive shaft, thus completely removing the travel motor from the drive shaft. This threaded drive method for disassembling the travel motor reduces the direct disassembly force on the motor, and the disassembly force is always along the axial direction of the drive shaft. This effectively protects the mating surfaces between the drive shaft and the travel motor, significantly improving the maintenance efficiency and accuracy of the entire stacker crane, extending the service life of the drive shaft and the travel motor, and reducing labor costs. Furthermore, threading one end of the mounting assembly to the drive shaft to securely connect the mounting assembly and the drive shaft, and tightening the other end of the mounting assembly allows the travel motor to be moved along a first direction to abut against the drive shaft. The direction is moved to the outer side of the push-pull motor to move the motor along the first direction to the mounting position on the outer side of the bracket, so as to realize the installation of the motor onto the drive wheel shaft. The above-mentioned installation of the motor by means of threaded drive can reduce the direct installation force on the motor, and the direction of the installation force is always along the axial direction of the drive wheel shaft. This can better protect the mating surface between the drive wheel shaft and the motor, greatly improve the maintenance efficiency and accuracy of the entire roadway stacker crane, extend the service life of the drive wheel shaft and the motor, and reduce labor costs. At the same time, the lifting assembly can be selectively moved to the underside of the motor to support it during disassembly and installation. This avoids the inability of the hoisting equipment to enter the maintenance site to hoist the motor due to its proximity to the ground and the confined space, thus reducing the difficulty of disassembling and assembling the motor.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] This embodiment proposes a walking motor disassembly and assembly device and a roadway stacker, such as Figure 1 and Figure 2 As shown, the stacker crane in the tunnel includes a ground rail 20 and a traveling mechanism 10. The ground rail 20 is fixedly installed on the ground and extends along the X-axis, with an I-shaped structure. The traveling mechanism 10 includes a bracket 101, a traveling motor 103, and two traveling wheel assemblies 102. The two traveling wheel assemblies 102 are spaced apart along the X-axis within the bracket 101. Each traveling wheel assembly 102 includes a main traveling wheel assembly and a driven traveling wheel assembly. The traveling motor 103 can drive the main traveling wheel assembly. The main traveling wheel assembly rotates to drive the driven traveling wheel assembly to rotate, so that the entire traveling mechanism 10 travels linearly along the X-axis on the ground rail 20. The main traveling wheel assembly includes a driving wheel axle 1021 and traveling wheels sleeved on the driving wheel axle 1021. The driving wheel axle 1021 extends axially to the outside of the bracket 101 and passes through the traveling motor 103. The traveling motor 103 is mounted in a mounting position on an outer side of the bracket 101. The traveling motor 103 is disassembled and installed based on the traveling motor disassembly and assembly device. The axial direction of the driving wheel axle 1021 is parallel to the Y-axis.

[0055] It is worth noting that the main improvement in this embodiment is the walking motor disassembly and assembly device. Therefore, the specific working principle of the walking mechanism 10 will not be described in detail here. Please refer to the existing roadway stacker crane.

[0056] Specifically, such as Figure 1 and Figure 2 As shown, the walking motor 103 includes a stepper motor 1031 and a gearbox 1032 connected to each other. The outer housing of the gearbox 1032 is fixedly mounted to the outer side of the bracket 101 by fastening bolts 1033, so that the circumferential rotation of the entire walking motor 103 can be restricted by the fastening bolts 1033. Furthermore, a mounting hole is coaxially provided at the center of the gearbox 1032. The diameter of the mounting hole is the same as the diameter of the drive shaft 1021, so that the drive shaft 1021 can pass into the mounting hole along the Y-axis, so that the radial movement of the entire walking motor 103 can be restricted by the mounting hole. At the same time, a flange 1034 is provided on the outer side of the gearbox 1032 away from the bracket 101. The flange 1034 can be snapped onto the drive shaft 1021 by an expansion sleeve, so that the axial movement of the entire walking motor 103 on the Y-axis can be restricted by the flange 1034 and the expansion sleeve.

[0057] Correspondingly, such as Figure 1 and Figure 2 As shown, when disassembling the travel motor 103, the flange 1034 needs to be removed from the gearbox 1032 first to release the axial restriction of the travel motor 103 on the Y-axis by the flange 1034 and the expansion sleeve; then, the fastening bolts 1033 are removed to release the restriction of the travel motor 103's circumferential rotation; finally, the travel motor 103 is pulled out axially from the drive shaft 1021 using the travel motor disassembly and assembly device to separate the travel motor 103 and the drive shaft 1021. Alternatively, the travel motor 103 can be installed using the reverse steps described above.

[0058] Furthermore, such as Figures 1 to 3 , Figure 7 As shown, the walking motor disassembly and assembly device includes a disassembly assembly 1, an installation assembly 2, and a lifting assembly 3. One end of the disassembly assembly 1 is threadedly connected to the walking motor 103, and the other end of the disassembly assembly 1 can move along a first direction to abut against the drive wheel shaft 1021. Twisting the disassembly assembly 1 can drive the walking motor 103 to move off the drive wheel shaft 1021 along a second direction, thus separating the walking motor 103 from the drive wheel shaft 1021. One end of the installation assembly 2 is threadedly connected to the drive wheel shaft 1021, and twisting the other end of the installation assembly 2 can move along a first direction to push against an outer side of the walking motor 103, thus moving the walking motor 103 along the first direction to a mounting position on an outer side of the bracket 101. The lifting assembly 3 can be selectively moved below the walking motor 103 to support the walking motor 103 during disassembly and assembly. The first direction and the second direction are opposite and both are parallel to the axial direction of the drive wheel shaft 1021, that is, both the first direction and the second direction are parallel to the Y-axis. The first direction is specifically as follows: Figure 1 , Figure 3 and Figure 7 As shown by arrow A in the diagram, the second direction is specifically as follows: Figure 1 , Figure 3 and Figure 7 As shown by arrow B in the diagram.

[0059] Compared with the prior art, the walking motor disassembly and assembly device in this embodiment changes the specific disassembly and assembly method of the walking motor 103. By threading one end of the disassembly component 1 to the walking motor 103, the disassembly component 1 and the walking motor 103 are fixedly connected. The other end of the disassembly component 1 can move along the first direction to press against the drive wheel shaft 1021. By twisting the disassembly component 1, the walking motor 103 can be moved off the drive wheel shaft 1021 along the second direction while pressing against the drive wheel shaft 1021, so as to completely remove the walking motor 103 from the drive wheel shaft 1021. The aforementioned method of disassembling the travel motor 103 using threaded transmission reduces the direct disassembly force on the travel motor 103, and the direction of the disassembly force is always along the axial direction of the drive wheel shaft 1021. This effectively protects the mating surfaces between the drive wheel shaft 1021 and the travel motor 103, greatly improving the maintenance efficiency and accuracy of the entire roadway stacker crane, extending the service life of the drive wheel shaft 1021 and the travel motor 103, and reducing labor costs. Furthermore, one end of the mounting component 2 is threadedly connected to the drive wheel shaft 1021 to securely connect the mounting component 2. The drive shaft 1021 is connected to the drive shaft, and the other end of the mounting assembly 2 is screwed to move along the first direction to an outer side of the push-pull motor 103, so as to move the motor 103 along the first direction to a mounting position on an outer side of the bracket 101, thereby mounting the motor 103 onto the drive shaft 1021. The above-mentioned threaded drive method for mounting the motor 103 can reduce the direct mounting force on the motor 103, and the direction of the mounting force is always along the axial direction of the drive shaft 1021, thereby better protecting the drive shaft 1021 and the motor 103. The mating surfaces between them greatly improve the maintenance efficiency and accuracy of the entire roadway stacker crane, extend the service life of the drive wheel axle 1021 and the travel motor 103, and reduce labor costs. At the same time, the lifting assembly 3 can be selectively moved to the underside of the travel motor 103 to support the travel motor 103 during disassembly and installation. This avoids the inability of hoisting equipment to enter the maintenance site to hoist the travel motor 103 due to its proximity to the ground and the limited space where the travel motor 103 is located, thus reducing the difficulty of disassembling and assembling the travel motor 103.

[0060] In other words, a disassembly and assembly component 2 is provided to optimize the disassembly and installation of the travel motor 103 and the drive wheel axle 1021, based on their external dimensions and mutual cooperation. This effectively improves the maintenance efficiency of the entire aisle stacker crane and reduces labor costs. Furthermore, to address the issue of the travel motor 103 being close to the ground and in confined space, a lifting component 3 is provided to replace hoisting equipment, greatly improving the convenience of disassembling and assembling the travel motor 103 and further enhancing the maintenance efficiency of the entire aisle stacker crane and reducing labor costs.

[0061] The following is a detailed description of disassembly component 1:

[0062] Specifically, such as Figures 3 to 5 As shown, the disassembly assembly 1 includes a fixed base 11, a connecting bolt 12, a push rod 13, and a limiting member 14. The connecting bolt 12 passes through the fixed base 11 along a first direction and is threaded to the travel motor 103. The push rod 13 is threaded through the fixed base 11 along the first direction. The end of the push rod 13 that extends out of the fixed base 11 along the first direction is coaxially connected to the limiting member 14. The limiting member 14 is used to press against the drive wheel shaft 1021 along the first direction. Rotating the push rod 13 around the drive wheel shaft 1021 axially can drive the fixed base 11 to move along the push rod 13 along a second direction, thereby driving the entire travel motor 103 to move out of the drive wheel shaft 1021 along the second direction.

[0063] Specifically, such as Figures 1 to 5 As shown, the gearbox 1032 of the walking motor 103 is provided with a first threaded hole 1035 that matches the connecting bolt 12. The connecting bolt 12 can be screwed into the first threaded hole 1035 to connect the disassembly assembly 1 to the walking motor 103. In addition, the fixing seat 11 is specifically a steel piece with a cross-shaped structure. A second threaded hole 16 is provided at the center of the fixing seat 11. The push rod 13 can be screwed into the second threaded hole 16.

[0064] Furthermore, such as Figures 3 to 5 As shown, multiple connecting bolts 12 are provided, and the multiple connecting bolts 12 are evenly arranged along the circumference of the fixing seat 11. The push rod 13 is located in the middle of each connecting bolt 12. That is, guide holes 17 that cooperate with the connecting bolts 12 are respectively provided on the four sides of the fixing seat 11, so that a connecting bolt 12 passes through a guide hole 17 in a first direction and is screwed into a first threaded hole 1035 on the gearbox 1032, thereby fixing the fixing seat 11 parallel and spaced on one side of the gearbox 1032. In this embodiment, a total of four connecting bolts 12 are provided, and correspondingly, four first threaded holes 1035 are provided on the gearbox 1032.

[0065] Specifically, such as Figures 4 to 6As shown, an annular step 121 is protruding on the outer circumferential surface of the connecting bolt 12. That is, the outer diameter of the annular step 121 is larger than the diameter of the first threaded hole 1035. This allows the annular step 121 to limit and abut against the outer side of the travel motor 103 when the connecting bolt 12 is screwed into the first threaded hole 1035 of the travel motor 103, thereby preventing the connecting bolt 12 from being screwed further into the first threaded hole 1035. This limits the screwing depth of each connecting bolt 12 into the first threaded hole 1035, ensuring that the four connecting bolts 12 are screwed into the first threaded hole 1035 to the same depth. This guarantees the parallelism between the fixing seat 11 and the travel motor 103 when fixed by the four connecting bolts 12, thereby achieving better disassembly and improving the maintenance accuracy of the entire roadway stacker crane.

[0066] Furthermore, such as Figure 4 and Figure 5 As shown, the end of the push rod 13 facing the walking motor 103 is an unthreaded cylindrical rod 131; the limiting member 14 includes an abutment block 141, a first bearing 142, and a cover 143; wherein, the outer ring of the first bearing 142 is installed in the abutment block 141, the cylindrical rod 131 passing through the second threaded hole 16 of the fixing seat 11 is inserted into the inner ring of the first bearing 142, and the cover 143 is placed on one end of the abutment block 141, thereby connecting the fixing seat 11, the push rod 13, the first bearing 142, the abutment block 141, and the cover 143 to form an integral structure.

[0067] Specifically, such as Figures 3 to 5 As shown, the end of the abutment block 141 away from the cover 143 has a first hole 1411 coaxially provided. The diameter of the first hole 1411 is smaller than the outer diameter of the first bearing 142 and larger than the outer diameter of the push rod 13, so that the push rod 13 can slide through the first hole 1411. The end of the abutment block 141 facing the cover 143 has a second hole 1412 coaxially provided. The second hole 1412 communicates with the first hole 1411. The diameter of the second hole 1412 is the same as the outer diameter of the first bearing 142, so that the first bearing 142 can be installed along the second hole 1412 on the abutment block. Inside block 141; and, a retaining ring 1413 is installed on the side of the second hole 1412 near the cover 143, so that the retaining ring 1413 limits and fixes the first bearing 142 into the second hole 1412; the inner diameter of the first bearing 142 is the same as the outer diameter of the cylindrical rod 131, so that the cylindrical rod 131 is inserted into the inner ring of the first bearing 142; thereby, the push rod 13, the abutment block 141 and the first bearing 142 can be fixedly connected to each other through the installation fit between the first bearing 142 and the second hole 1412 and the cylindrical rod 131 respectively.

[0068] By making the diameter of the cover 143 the same as the diameter of the second hole 1412 in the abutment block 141, the cover 143 can be fitted into the second hole 1412, thereby providing dust protection for the first bearing 142 through the cover 143, and thus improving the service life of the first bearing 142.

[0069] Furthermore, by connecting the first bearing 142 to the push rod 13 and the abutment block 141 respectively, that is, by the installation fit between the first bearing 142 and the push rod 13 and the abutment block 141 respectively, the push rod 13, the abutment block 141 and the first bearing 142 can be fixed together; at the same time, by providing a second hole 1412 and a retaining ring 1413 in the abutment block 141 for installing the first bearing 142, the axial movement of the first bearing 142 along the Y-axis in the abutment block 141 can be constrained; by adopting the above installation fit method, the contact surface between the cover 143 and the drive wheel shaft 1021 can be better ensured, as well as the coaxiality between the push rod 13 and the drive wheel shaft 1021, thereby achieving better disassembly effect and maintenance accuracy.

[0070] Furthermore, such as Figures 3 to 5 As shown, the disassembly assembly 1 also includes a vertical rod 15, which is vertically connected to the top rod 13. The end of the top rod 13 that is not connected to the fixed base 11 is placed in the middle of the vertical rod 15. Rotating the vertical rod 15 can drive the top rod 13 to rotate around the axial direction of the drive wheel shaft 1021. That is, a connecting hole 18 is provided at the end of the top rod 13 that is not connected to the fixed base 11. The diameter of the vertical rod 15 is the same as the diameter of the connecting hole 18, so that the vertical rod 15 can be directly passed through the connecting hole 18. Thus, the rotation of the top rod 13 can be provided by rotating the vertical rod 15, making the rotation of the top rod 13 more time-saving, labor-saving, simple and convenient.

[0071] In this embodiment, the specific disassembly process of the walking motor 103 by disassembly component 1 is as follows: the flange 1034 and fastening bolts 1033 have been removed from the gearbox 1032 beforehand, and the lifting component 3 supports and lifts the walking motor 103 throughout the entire disassembly process.

[0072] First, pass the four connecting bolts 12 through the four guide holes 17 of the fixed base 11, and screw the four connecting bolts 12 into the four first threaded holes 1035 on the gearbox 1032 of the walking motor 103.

[0073] Then, screw the push rod 13 into the second threaded hole 16 of the fixing seat 11, and after the cylindrical smooth rod 131 of the push rod 13 is completely passed out of the second threaded hole 16, install the abutment block 141, the first bearing 142, the retaining ring 1413 and the cover 143 on the cylindrical smooth rod 131 in sequence.

[0074] Finally, the vertical rod 15 is inserted into the connecting hole 18 of the top rod 13, and the vertical rod 15 is rotated around the axial direction (Y-axis) of the drive wheel shaft 1021 to drive the top rod 13 to rotate around the Y-axis, so that the top rod 13 moves relative to the fixed seat 11 in the first direction until the cover 143 presses against the drive wheel shaft 1021; then, the vertical rod 15 is rotated again. At this time, due to the pressing action between the top rod 13 and the drive wheel shaft 1021, the top rod 13 cannot continue to move in the first direction. Correspondingly, due to the threaded transmission between the fixed seat 11 and the top rod 13, the fixed seat 11 can move on the top rod 13 in the second direction under the rotation of the top rod 13, so as to drive the entire walking motor 103 away from the drive wheel shaft 1021 in the second direction until the walking motor 103 is completely removed from the drive wheel shaft 1021.

[0075] In this embodiment, the disassembly assembly 1 ensures the fitting accuracy of the mating surfaces between the drive wheel shaft 1021 and the cover 143 on the top rod 13 by setting a limiting member 14. At the same time, the threaded transmission method between the top rod 13 and the fixed seat 11 can reduce the direct force on the travel motor 103, which is suitable for the travel motor 103, which is made of brittle material and cannot withstand excessive force. This can extend the service life of the travel motor 103 and the drive wheel shaft 1021. Furthermore, during the disassembly process, the direction of the force is always along the axial direction of the drive wheel shaft 1021, which improves the maintenance accuracy of the entire roadway stacker crane.

[0076] The following is a detailed description of installation component 2:

[0077] Specifically, such as Figures 7 to 10 As shown, the mounting assembly 2 includes a pull rod 21, a nut 22, a second bearing 23, and a pressure block 24. One end of the pull rod 21 is threaded into the drive wheel shaft 1021 along a second direction. The nut 22 is threaded onto the end of the pull rod 21 that extends out of the drive wheel shaft 1021. The second bearing 23 is located between the pressure block 24 and the nut 22. A cylindrical platform 221 is provided at the end of the nut 22 near the second bearing 23. The outer diameter of the cylindrical platform 221 is the same as the inner diameter of the second bearing 23, so that the cylindrical platform 221 is inserted into the inner ring of the second bearing 23. The pull rod 21 passes through the pressure block 24, the inner ring of the second bearing 23, and the nut 22 in sequence. The nut 22 is rotated axially around the drive wheel shaft 1021 so that the nut 22 can push the motor 103 to the mounting position along the first direction on the pull rod 21.

[0078] Specifically, such as Figure 7 and Figure 8As shown, a third threaded hole is provided on the drive shaft 1021, and the pull rod 21 is threaded into the third threaded hole to connect the mounting assembly 2 to the drive shaft 1021. Furthermore, a hexagonal step 211 is annularly protruding on the outer circumference of the pull rod 21. When the pull rod 21 is threaded into the third threaded hole, the hexagonal step 211 can limit and abut against the end face of the drive shaft 1021, thereby restricting the pull rod 21 from continuing to screw into the third threaded hole. This controls the distance the pull rod 21 screws into the drive shaft 1021, effectively preventing the fixed connection between the mounting assembly 2 and the drive shaft 1021 from being unstable due to the pull rod 21 screwing into the drive shaft 1021 too short a distance. Moreover, since the hexagonal step 211 is limited and abuts against the end face of the drive shaft 1021, the drive shaft 1021 can provide a certain limiting effect on the pull rod 21, preventing the pull rod 21 from rotating. The nut 22 is provided with a fourth threaded hole that can be threaded into the pull rod 21, so that the nut 22 can be directly screwed into the pull rod 21.

[0079] Specifically, such as Figures 8 to 10 As shown, the pressure block 24 includes a first ring 241 and a second ring 242. The second ring 242 is connected to the side of the first ring 241 near the second bearing 23. The outer diameter of the first ring 241 is larger than the outer diameter of the second ring 242, and the inner diameter of the first ring 241 is larger than the diameter of the drive wheel shaft 1021. This ensures that the pressure block 24 does not contact the drive wheel shaft 1021 during the process of pushing the motor 103, thus preventing damage to the drive wheel shaft 1021. The inner diameter of the second ring 242 matches the outer diameter of the second bearing 23, so that the second bearing 23 fits against one side of the second ring 242, ensuring a good fit between the pressure block 24 and the second bearing 23. Furthermore, the inner diameter of the second ring 242 is larger than the diameter of the pull rod 21, allowing the pull rod 21 to pass directly through the first ring 241 and the second ring 242 to fit the pressure block 24 onto the pull rod 21.

[0080] By connecting the second bearing 23 to the nut 22 and ensuring a tight fit between the second bearing 23 and the pressure block 24, and by applying an axial force to the pressure block 24 during the installation of the second bearing 23, the tie rod 21, nut 22, second bearing 23, and pressure block 24 can be fixed together. This effectively improves the fit between the pressure block 24 and the travel motor 103, as well as the coaxiality between the tie rod 21 and the drive wheel shaft 1021, thereby achieving better disassembly results and improving maintenance accuracy.

[0081] In this embodiment, the specific installation process of the walking motor 103 using mounting component 2 is as follows:

[0082] First, the lifting assembly 3 is moved below the travel motor 103 to support the travel motor 103. Then, the pull rod 21 is screwed into the third threaded hole of the drive wheel shaft 1021 along the second direction thread to fix the pull rod 21 to the drive wheel shaft 1021. At this time, the hexagonal step 211 on the pull rod 21 is limited and abuts against the end face of the drive wheel shaft 1021.

[0083] Then, the pressure block 24 is fitted onto the part of the pull rod 21 that extends out of the drive wheel shaft 1021, and the first ring 241 is aligned with the travel motor 103; then the cylindrical platform 221 on the nut 22 is installed onto the inner ring of the second bearing 23, so that the second bearing 23 is installed on the nut 22; and the nut 22 is screwed into the pull rod 21.

[0084] Then, the nut 22 is turned around the axial direction (Y-axis) of the drive wheel shaft 1021, so that the nut 22, the second bearing 23 and the pressure block 24 move together in the first direction until the first ring 241 of the pressure block 24 presses against the travel motor 103; then the nut 22 is turned again, so that through the thread transmission between the nut 22 and the pull rod 21, the nut 22 pushes the travel motor 103 against the first ring 241 and moves it in the first direction, so as to push the travel motor 103 to move linearly on the drive wheel shaft 1021 to the mounting position outside the bracket 101; at this time, the travel motor 103 is always supported by the lifting assembly 3.

[0085] Finally, the flange 1034 is attached to the drive wheel shaft 1021 by the expansion sleeve, and the gearbox 1032 is fixedly installed on the mounting position on the outside of the bracket 101 by the fastening bolts 1033; thus, the installation process of the travel motor 103 is completed.

[0086] In this embodiment, the installation component 2, by setting up a mutually cooperating pressure block 24, a second bearing 23, and a nut 22, can ensure the fitting accuracy of the mating surface between the first ring 241 of the pressure block 24 and the travel motor 103. At the same time, the use of a threaded transmission method between the pull rod 21 and the nut 22 can reduce the direct force on the travel motor 103, which is suitable for the characteristics of the travel motor 103, which is made of brittle materials and cannot withstand excessive force. This can extend the service life of the travel motor 103 and the drive wheel axle 1021. Furthermore, during the installation process, the direction of the force is always along the axial direction of the drive wheel axle 1021, which improves the maintenance accuracy of the entire roadway stacker crane.

[0087] The following is a detailed description of the lifting assembly 3:

[0088] Specifically, such as Figure 1 , Figure 7 and Figure 11As shown, the lifting assembly 3 includes a hydraulic module 31 and a support plate 32. The hydraulic module 31 is connected to one side of the support plate 32. The hydraulic module 31 drives the support plate 32 to move along the Z-axis, positioning the support plate 32 below the travel motor 103, thus ensuring that the support plate 32 consistently supports the travel motor 103 throughout the entire disassembly and installation process. The hydraulic module 31 can employ a commonly used hydraulic structure in the prior art.

[0089] By providing lifting power to the travel motor 103 through the hydraulic module 31, the problems of inconvenient maintenance and easy damage to parts caused by the large mass of the travel motor 103 can be solved, and labor costs can be effectively reduced. In addition, the support plate 32 provides a bearing surface for disassembling and assembling the travel motor 103, and the support plate 32 can also provide a storage space for the disassembled travel motor 103, thereby improving the convenience of maintenance.

[0090] It is worth noting that, based on the flat bottom of the traveling motor 103, the lifting assembly 3 is used instead of the hoisting equipment. Therefore, in the structural selection of the lifting assembly 3, a hydraulic module 31 should be selected that can meet the requirement that the lifting point is lower than the installation position of the traveling motor 103 on the Z-axis, and that the width and height meet the requirements of the maintenance environment. This can effectively solve the problem that the hoisting equipment cannot enter the maintenance site due to the travel motor 103 being close to the ground and the narrow space for disassembly and assembly. This greatly improves the convenience of disassembling and assembling the traveling motor 103, further improves the maintenance efficiency of the entire roadway stacker crane and reduces labor costs.

[0091] In this embodiment, the walking motor disassembly and assembly device is designed with a disassembly component 1 and an installation component 2 that are compatible with the walking motor 103, taking into account the external dimensions and mutual assembly method of the walking motor 103 and the drive wheel axle 1021. This optimizes the disassembly and assembly of the walking motor 103, effectively improving the maintenance efficiency of the roadway stacker crane and reducing labor costs. At the same time, in view of the problem that the walking motor 103 is close to the ground and the maintenance space is compact and narrow, a lifting component 3 is designed to replace the hoisting equipment, which greatly improves the convenience of disassembling and assembling the walking motor 103, further improving the maintenance efficiency of the roadway stacker crane and reducing labor costs.
