[0022] As Figure 1 and Figure 2As shown, the present application provides a walking wheel dismounting device, which comprises a support rail 100, a first lifting support mechanism 200, a lifting seat 300, a second lifting support mechanism 400, a temporary support table 520 and a sliding support table 510; the support rail 100 is arranged along the length direction of the vehicle 800 and is provided with a mounting gap 110; the lifting seat 300 is arranged in the mounting gap 110, and the sliding support table 510 and the temporary support table 520 are arranged side by side above the lifting seat 300 in the width direction of the vehicle 800, the top surface of the sliding support table 510 and the top surface of the temporary support table 520 are configured to be in abutment with the top surface of the support rail 100 to support different walking wheels 831 respectively; the temporary support table 520 is detachably connected with at least one of the lifting seat 300 and the support rail 100, the sliding support table 510 is slidingly connected with the lifting seat 300 in the width direction of the vehicle 800, and the sliding support table 510 is configured to slide relative to the lifting seat 300 in the width direction after the temporary support table 520 is detached to move to the position below the walking wheel 831 corresponding to the temporary support table 520 before the temporary support table 520 is detached; the first lifting support mechanism 200 is arranged at the periphery of the mounting gap 110 to support the frame 832 of the bogie 830 of the vehicle 800 when the walking wheel 831 of the bogie 830 walks to the mounting gap 110; the second lifting support mechanism 400 is connected with the lifting seat 300 to drive the lifting seat 300 to lift.

[0023] Specifically, in the present specification, the number of walking wheels 831 of the bogie 830 of the vehicle 800 is taken as two, and the two walking wheels 831 are arranged side by side in the width direction as an example for description, in this case, in the initial state of the walking wheel dismounting device A1, the top surface of the sliding support table 510 and the top surface of the temporary support table 520 are in abutment with the top surface of the support rail 100, the sliding support table 510 and the temporary support table 520 respectively constitute the support structure of the two walking wheels 831, the walking wheel 831 corresponding to the sliding support table 510 is defined as the first wheel 831A, and the walking wheel 831 corresponding to the temporary support table 520 is defined as the second wheel 831B, when the sliding support table 510 and the temporary support table 520 are arranged side by side and in abutment with the top surface of the support rail 100, the sliding support table 510, the temporary support table 520 and the support rail 100 constitute a complete walking track, which can be used for the walking of the walking wheels 831 of the bogie 830 of the vehicle 800. However, it should be understood that the number of walking wheels 831 equipped on the same bogie 830 can be more than two without violating the design concept of the present application, in this case, the temporary support table 520 or the sliding support table 510 can be used to form the support for multiple walking wheels 831, which will not be described in detail here.

[0024] It should be noted that the temporary support table 520 can be detachably connected with the support rail 100 only, and the connection structure between the two is usually staggered with the walking channel of the second wheel 831 in the vehicle length direction, on the basis of which, the position and connection mode of the connection structure between the two are not limited, and the dismounting mode of the temporary support table 520 is not limited.

[0025] The temporary support table 520 can also be detachably connected with the lifting seat 300 only, for example, the temporary support table 520 can be lifted with the lifting seat 300, so that the lifting seat 300 moves to a position suitable for dismounting the temporary support table 520. Subsequently, the content of the present application will be mainly illustrated based on this scheme.

[0026] The temporary support table 520 can be detachably connected with both the support rail 100 and the lifting seat 300, in which case, the detachable mode of the temporary support table 520 and the support rail 100 is not limited, for example, the two can be connected only in the up-down direction, and the temporary support table 520 can be lowered with the lifting seat 300 to realize the insertion connection of the temporary support table 520 and the support rail 100, and the temporary support table 520 can be raised with the lifting seat 300 to realize the separation of the insertion structure of the temporary support table 520 and the support rail 100, which will not be described in detail here.

[0027] During the dismounting operation, the first lifting support mechanism 200 replaces the walking wheel 831 to become the main load-bearing structure of the vehicle 800. The second lifting support mechanism 400 is an actuating device for driving the lifting seat 300 and its load-bearing structure to move up and down. The specific scheme of the first lifting support mechanism 200 and the second lifting support mechanism 400 is not limited, which will be exemplarily illustrated later. The sliding of the sliding support table 510 relative to the lifting seat 300 can be manually driven or other driving modes, for example, electrically driven, which will be exemplarily illustrated later.

[0028] When the running wheel dismounting device is in the initial state, i.e., the sliding support platform 510 and the temporary support platform 520 are arranged side by side and abut against the top surface of the support rail 100, the sliding support platform 510, the temporary support platform 520 and the support rail 100 form a complete running rail, and the vehicle 800 to be maintained runs through the installation gap 110 by the running wheels 831 until the two running wheels 831 are supported on the temporary support platform 520 and the sliding support platform 510 respectively, and the projection of the running wheels 831 in the horizontal direction on the front-rear direction is located in the region between the front and rear edges of the installation gap 110, i.e., the installation gap 110 can be used for the passing of the running wheels 831, which is defined as the second state in the running wheel 831 dismounting process. At this time, the first lifting support mechanism 200 performs the jacking movement on the frame 832 of the bogie 830, and the first lifting support mechanism 200 supports the frame 832 and the vehicle body and the like supported thereby, and replaces the running wheels 831 to become the main load-bearing structure of the vehicle 800, which is defined as the third state in the running wheel 831 dismounting process. Then the temporary support platform 520 can be removed, and only the sliding support platform 510 is left, which is defined as the fourth state in the running wheel 831 dismounting process. Then under the action of the second lifting support mechanism 400, the sliding support platform 510 can form the support for a certain running wheel 831, for example, the first wheel 831A, which is defined as the fifth state in the running wheel 831 dismounting process. Then the dismounting of the first wheel 831A is performed, and then the sliding support platform 510 can drive the first wheel 831A to move in the vehicle width direction away from the second wheel 831B, so that the first wheel 831A is separated from the mounting position, which is defined as the sixth state in the running wheel 831 dismounting process. The second lifting support mechanism 400 drives the lifting seat 300 and the structure supported thereby to perform the descending movement, so that the first wheel 831A moves downward and is separated from the space formed by the frame 832 for accommodating the running wheel, and moves to a position facilitating the taking out of the first wheel 831A, which is defined as the seventh state in the running wheel 831 dismounting process. In this process, the sliding support platform 510 can adjust its position in the vehicle width direction as needed to facilitate the taking out of the first wheel 831A from the sliding support platform 510 in the seventh state. Then the second lifting support mechanism 400 drives the lifting seat 300 and the structure supported thereby to perform the ascending movement, and the sliding support platform 510 is adjusted in position until the sliding support platform 510 forms the support for the second wheel 831B below the second wheel 831B, which is defined as the eighth state in the running wheel 831 dismounting process.Then the second round 831B is disassembled, and the second round 831B can be driven by the sliding support table 510 to move in the vehicle width direction, so that the second round 831B is separated from its installation position, and then the second lifting support mechanism 400 drives the lifting seat 300 and the structure carried thereby to move downward, so that the second round 831B moves downward and is separated from the space formed by the frame 832 for accommodating the running wheel, and moves to a position convenient for taking out the second round 831B, defining this state as the ninth state in the disassembly process of the running wheel 831. During this process, the sliding support table 510 can adjust its position in the vehicle width direction as needed to facilitate the taking out of the second round 831B from the sliding support table 510 in the ninth state. The installation process of the running wheel 831 can be opposite to this process, which will not be described in detail here.

[0029] Thus, in the running wheel dismounting device of the embodiment, the support rail 100 is arranged along the length direction of the vehicle 800, and is provided with a mounting gap 110, the lifting seat 300 is arranged in the mounting gap 110, the sliding support table 510 and the temporary support table 520 are arranged side by side above the lifting seat 300 in the width direction of the vehicle 800, and the top surface of the sliding support table 510 and the top surface of the temporary support table 520 are configured to be abuttable with the top surface of the support rail 100, so that when the top surface of the sliding support table 510 and the top surface of the temporary support table 520 are abutted with the top surface of the support rail 100, the sliding support table 510, the temporary support table 520 and the support rail 100 form a complete running track, and the running wheels 831 of the bogie 830 of the vehicle 800 can run on the running track to move above the mounting gap 110 or away from the mounting gap 110, when the running wheels 831 of the bogie 830 of the vehicle 800 move above the mounting gap 110 and a plurality of, for example, two running wheels 831 are supported on the sliding support table 510 and the temporary support table 520 respectively, the frame 832 of the bogie 830 can be supported by the first lifting support mechanism 200 to replace the running wheels 831 to support the frame 832 and the vehicle body; after the temporary support table 520 is dismounted, the plurality of running wheels 831 can be dismounted one by one by means of the lifting function of the lifting seat 300 driven by the second lifting support mechanism 400 and the sliding function of the sliding support table 510. The arrangement of the running wheel dismounting device does not have special requirements for the structure of the bogie 830 of the vehicle 800, and the bogie 830 does not need to reserve additional working space for the arrangement of the running wheel dismounting device when the bogie 830 is designed, and the dismounting of the running wheels 831 can be completed by means of the size allowance of the space on the frame 832 for mounting the running wheels 831 in the width direction (the allowance is generally used for placing the running wheels 831 in the space), and there is no need to dismount the guide wheels 833 or the stabilizing wheels 834 in advance. The running wheel dismounting device of the embodiment is compact in structure, facilitates the dismounting of the running wheels 831 of the track vehicle 800, and can reduce the requirements for the internal space of the vehicle 800 or the space between the bogie 830 and the vehicle body chassis of the vehicle 800, and is simple in structure and strong in practicality.

[0030] As shown in Figures 3 to 5 the above embodiment, optionally, the running wheel dismounting device further comprises a running wheel clamping tool 700, the running wheel clamping tool 700 is arranged above the sliding support table 510 and is detachably connected with the sliding support table 510, the running wheel clamping tool 700 is provided with a running wheel limiting space 710, and an open end 711 for the running wheels 831 to pass through is arranged at the upper end of the running wheel limiting space 710.

[0031] The traveling wheel clamping tool 700 can be flexibly installed or removed according to the work requirements. When the traveling wheel clamping tool 700 is detached from the sliding support table 510, the sliding support table 510 can be used to constitute the above-mentioned walking track of the traveling wheel 831, thereby being used for walking of the traveling wheel 831. When the traveling wheel clamping tool 700 is connected with the sliding support table 510, the sliding support table 510 can be positioned and accommodated by the traveling wheel limiting space 710 of the traveling wheel clamping tool 700, thereby ensuring the position reliability of the traveling wheel 831 in the process of detaching or installing the traveling wheel 831, and thereby improving the detaching efficiency and detachable controllability of the traveling wheel 831.

[0032] The detachable manner of the traveling wheel clamping tool 700 is not limited, and the connecting interface thereof does not affect the support of the sliding support table 510 to the traveling wheel 831 after the traveling wheel clamping tool 700 is detached. This will be exemplarily described later.

[0033] In some scenarios, when the second lifting support mechanism 400 drives the lifting seat 300 to move downward to the first position, one or more of the following operations can be performed: disassembly of the traveling wheel clamping tool 700, taking and placing of the traveling wheel 831, and disassembly of the temporary support table 520. When the lifting seat 300 is located at the first position, the distance between the temporary support table 520 and the lowest point (for example, the lower end of the stabilizing wheel 834) of the bogie 830 at the installation gap 110 can be greater than the diameter of the traveling wheel 831, thereby facilitating taking out of the traveling wheel 831.

[0034] The depth of the traveling wheel limiting space 710 in the up-down direction is less than the distance from the lower end of the traveling wheel 831 to the lower end of the fixed structure thereof, for example, less than the distance from the lower end of the traveling wheel 831 to the lower end of the fixed bolt located at the lowermost position.

[0035] After the support of the frame 832 and the vehicle body by the first lifting support mechanism 200 is replaced by the running wheel 831, the opening 711 of the running wheel limiting space 710 of the running wheel clamping tool 700 is made to correspond to the lower end of the running wheel 831 (to be disassembled) through the sliding movement of the sliding support table 510. The running wheel clamping tool 700 is made to move relative to the running wheel 831 in the up-down direction through the upward movement of the lifting seat 300 driven by the second support mechanism, until the running wheel limiting space 710 limits the running wheel 831 in the longitudinal direction and the lateral direction of the vehicle. At this time, the running wheel 831 can be supported by the running wheel clamping tool 700 and / or the sliding support table 510. Then the fixed structure of the running wheel 831, such as a fixed bolt, can be disassembled. When the fixed bolt is disassembled, the running wheel 831 can be made to move along the axial direction of the driving shaft and be separated from the driving shaft through the outward movement of the sliding support table 510 in the lateral direction of the vehicle, in combination with the movement requirement of the disassembly movement of the running wheel 831. In this process, the running wheel clamping tool 700 limits the running wheel 831, and the movement stroke requirement in the lateral direction of the vehicle can be met by using the space originally used by the frame 832 to install the running wheel 831, without causing the collision between the running wheel 831 and the frame 832 of the bogie 830 in the lateral direction of the vehicle. When the running wheel 831 is separated from the driving shaft, the lifting seat 300 is lowered through the downward movement of the second lifting support mechanism 400, until the lifting seat 300 moves to a position suitable for the removal of the running wheel 831, such as the first position mentioned above.

[0036] As shown in Figure 3 and Figure 4 , in the optional scheme of the running wheel clamping tool 700, the running wheel clamping tool 700 includes limiting frames 720, two limiting frames 720 are distributed in the lateral direction of the vehicle and are detachably connected with the sliding support table 510, and the running wheel limiting space 710 is surrounded between the two limiting frames 720.

[0037] Specifically, the two limiting frames 720 are arranged relative to each other in the lateral direction of the vehicle. The limiting frame 720 can have a first baffle plate in the lateral direction of the vehicle and a second baffle plate at both ends in the longitudinal direction of the vehicle, and the first baffle plate and the second baffle plate are integrally connected.

[0038] In this way, the running wheel clamping tool 700 is formed by the two limiting frames 720. Compared with the overall tool, the manufacturing of the limiting frame 720 is relatively simpler, and the limiting frame 720 can be repaired or replaced separately, which is conducive to reducing the manufacturing difficulty and maintenance cost of the running wheel clamping tool 700.

[0039] As shown in Figure 4 , in the optional scheme of the running wheel clamping tool 700, the top end of the sliding support table 510 is provided with a mounting interface 511, and the running wheel clamping tool 700 is provided with a mounting matching interface 721 connected with the mounting interface 511.

[0040] Further, the mounting interface 511 is a recess structure at the top end of the sliding support table 510. The recess structure can be a hole structure or a groove structure, so as to avoid interference of the mounting interface 511 with the running wheel 831 when the running wheel clamping tool 700 is in the disassembled state with the sliding support table 510.

[0041] In a further optional solution of the running wheel clamping tool 700, the mounting interface 511 is a plug-in hole, and the mounting matching interface 721 is a plug-in column, which is plug-in connected with the plug-in hole.

[0042] Specifically, the lower end of the limiting frame 720 is provided with a plurality of, for example, two plug-in columns distributed in the vehicle length direction, and the sliding support table 510 is provided with a plurality of plug-in holes corresponding to the plurality of plug-in columns respectively. When the plug-in column is plugged into the plug-in hole, the top surface of the sliding support table 510 and the limiting frame 720 abut in the up-down direction.

[0043] In this way, it is convenient to quickly disassemble the running wheel clamping tool 700 and the sliding support table 510, and the structure is simple and practical.

[0044] In the above embodiment, optionally, in the initial state of the running wheel dismounting device A1, the running wheel dismounting device further comprises a sliding driving mechanism 600, which is partially located below the sliding support table 510 and partially located below the temporary support table 520, and is connected with the sliding support table 510 and the lifting seat 300 respectively, to drive the sliding support table 510 to slide in the vehicle width direction.

[0045] Reference Figure 4 As shown, specifically, the sliding driving mechanism 600 comprises a first transmission member, a second transmission member and a driving member 630, the first transmission member is located below the sliding support table 510 and is mounted on the sliding support table 510, the second transmission member is partially located below the sliding support table 510 and partially located below the temporary support table 520, and is mounted on the lifting seat 300, the first transmission member and the second transmission member are in transmission connection, and the driving member 630 is used to drive the first transmission member and the second transmission member to transmit, so as to drive the sliding support table 510 to slide in the vehicle width direction.

[0046] In the initial state, the projection of the sliding driving mechanism 600 in the up-down direction in the horizontal plane is covered by the projection of the lifting seat 300 in the up-down direction in the horizontal plane.

[0047] In this way, the sliding drive mechanism 600 can be used to achieve the sliding drive of the sliding support platform 510 in the vehicle width direction, which can reduce the reliance on manpower during the disassembly and assembly of the running wheels 831. The sliding drive mechanism 600 is partially located below the sliding support platform 510 and partially located below the temporary support platform 520, which can ensure that the sliding support platform 510 can obtain a relatively large sliding stroke. The structure is simple and highly practical.

[0048] like Figure 4 As shown, in a further alternative embodiment of the sliding drive mechanism 600, the first transmission member is a nut structure 610, and the second transmission member is a lead screw structure 620. The nut structure 610 is tractably mounted about its axis to the bottom of the sliding support platform 510 (e.g., see reference 620). Figure 7 The nut structure 610 is mounted on the first connecting seat 513 located at the bottom of the sliding support platform 510, and the screw structure 620 is rotatably mounted on the top of the lifting seat 300 about its axis (e.g., see reference). Figure 10 The top of the lifting seat 300 is provided with two second connecting seats 330 for mounting the lead screw structure 620. They extend along the vehicle width direction, partly located below the sliding support platform 510 and partly located below the temporary support platform 520. The driving member 630 is used to drive the nut structure 610 and the lead screw structure 620 to transmit power, so that the nut structure 610 drives the sliding support platform 510 to translate in the vehicle width direction.

[0049] Specifically, the axial direction of the nut structure 610 and the axial direction of the lead screw structure 620 extend in the vehicle width direction. The nut structure 610 is sleeved on the lead screw structure 620, and the two are connected by threaded transmission to form a ball screw pair. The driving component 630 may include a drive motor, which is located at one end of the lead screw structure 620 and is coaxially arranged with the lead screw structure 620. The drive motor drives the lead screw structure 620 to rotate, thereby driving the nut structure 610 to move in the vehicle width direction, thereby realizing the movement of the sliding support platform 510 in the vehicle width direction.

[0050] In a further alternative embodiment of the sliding drive mechanism 600, when the sliding support platform 510 and the temporary support platform 520 are arranged side by side and respectively in contact with the top surface of the support rail 100, the distance between the first end of the nut structure 610 and the lead screw structure 620 in the vehicle width direction is greater than the dimension of the temporary support platform 520 in the vehicle width direction. The first end is the end of the lead screw structure 620 located below the temporary support platform 520, so that after the temporary support platform 520 is disassembled, the nut structure 610 can move towards the first end and cause part of the sliding support platform 510 to extend beyond the edge of the support rail 100 in the vehicle width direction.

[0051] like Figure 4 As shown, the first end is Figure 4In the initial state of the middle end of the lead screw structure 620, the distance between the nut structure 610 and the left end of the lead screw structure 620 is greater than the size of the temporary support platform 520 in the vehicle width direction, so that when the temporary support platform 520 is removed, the driving motor can drive the lead screw structure 620 to rotate, and the driving is transmitted to the nut structure 610, so that the nut structure 610 moves towards the first end of the lead screw structure 620. The stroke of the nut structure 610 moving to the left end can be greater than the size of the temporary support platform 520 in the vehicle width direction, so that part of the sliding support platform 510 exceeds the edge of the support rail 100 in the vehicle width direction close to the first end, that is, it can exceed the left edge of the support rail 100. In some scenarios, it is convenient to disassemble and assemble the walking wheel clamping tool 700 on the sliding support platform 510 on the left side of the support rail 100, take and place the walking wheel 831, and the like. In some scenarios, the temporary support platform 520 can also be removed on the left side of the support rail 100.

[0052] In a further optional solution of the sliding drive mechanism 600, when the sliding support platform 510 and the temporary support platform 520 are arranged side by side and respectively abut the top surface of the support rail 100, the distance between the nut structure 610 and the second end of the lead screw structure 620 in the vehicle width direction is greater than the preset size, and the second end is the end of the lead screw structure 620 below the sliding support platform 510, so that after the temporary support platform 520 is removed, the nut structure 610 can move towards the second end and make part of the sliding support platform 510 exceed the edge of the support rail 100 in the vehicle width direction.

[0053] Exemplarily, the preset size can be one fifth, one fourth, or the like of the size of the sliding support platform 510 in the vehicle width direction, which will not be described in detail here.

[0054] In this case, it is convenient to disassemble and assemble the walking wheel clamping tool 700 on the sliding support platform 510 on the right side of the support rail 100, take and place the walking wheel 831, and the like. In some scenarios, the temporary support platform 520 can also be removed on the left side of the support rail 100.

[0055] In the above embodiment, optionally, in the initial state, the distance between the nut structure 610 and the first end of the lead screw structure 620 in the vehicle width direction is greater than the size of the temporary support platform 520 in the vehicle width direction, and the distance between the nut structure 610 and the second end of the lead screw structure 620 in the vehicle width direction is greater than the preset size, so that the sliding support platform 510 can move to exceed the left edge of the support rail 100, and can move to exceed the right edge of the support rail 100.

[0056] In some scenarios, in the initial state described above, the difference between the distance between the end of the nut structure 610 near the first end and the first end of the screw structure 620 in the vehicle width direction and the size of the temporary support platform 520 in the vehicle width direction, and the first distance are equal. The first distance is the distance between the end of the nut structure 610 near the second end and the second end of the screw structure 620.

[0057] like Figures 6 to 10 As shown in the above embodiment, a sliding connection structure is provided between the lifting seat 300 and the sliding support platform 510. The sliding connection structure includes a guide groove 320 and a guide rail 512. The guide groove 320 can be a T-shaped groove and is set at the top of the lifting seat 300. The guide rail 512 can be a T-shaped rail and is set at the bottom of the sliding support platform 510. The length of the guide groove 320, the length of the guide rail 512 and the dimension of the lifting seat 300 in the vehicle width direction are consistent.

[0058] like Figure 4 As shown in the above embodiment, optionally, the first lifting support mechanism 200 includes a piston chamber structure 220 and a lifting column 210. The support rail 100 has multiple piston chamber structures 220 built into both sides of the mounting notch 110 in the vehicle length direction. The lifting column 210 is connected to the piston chamber structure 220 through a piston. When the running wheels 831 of the bogie 830 of the vehicle 800 travel to the mounting notch 110 (when the two running wheels 831 travel to the sliding support platform 510 and the temporary support platform 520 respectively), the positions of the lifting columns 210 on both sides of the mounting notch 110 in the vehicle length direction correspond to the positions of the front and rear crossbeams of the frame 832. The lifting column 210 can move upward to lift the frame 832 of the bogie 830.

[0059] The piston chamber structure 220 can be detachably connected to the support rail 100, or it can be integrally formed into the support rail 100; this is not a limitation and will not be described in detail here. In the first lifting support structure, the lifting column 210 is hydraulically or pneumatically driven.

[0060] like Figure 4 As shown in the above embodiment, optionally, the support rail 100 has receiving portions 120 at both ends of the mounting notch 110 in its length direction. The receiving portions 120 are spaced apart from the top surface of the support rail 100 and communicate with the mounting notch 110. The lifting seat 300 is partially received in the mounting notch 110 and partially received in the receiving portion 120. The second lifting support mechanism 400 is partially received in the receiving portion 120.

[0061] Specifically, the accommodation portion 120 is formed by a missing portion of the support rail 100 adjacent to the mounting notch 110, two accommodation portions 120 are respectively arranged at the edges of the support rail 100 at both ends of the mounting notch 110 in the X-axis direction, the lifting seat 300 is provided with a limiting block 310 at a position spaced from the top surface thereof, the limiting block 310 is accommodated in the accommodation portion 120, and the limiting block 310 is connected with the second lifting support mechanism 400.

[0062] In some scenarios, the position of the piston cavity structure 220 can also correspond to the position of the accommodation portion 120, so as to facilitate the disassembly and assembly of the lifting column 210.

[0063] Optionally, the second lifting support mechanism 400 comprises a screw structure 410 and a rotating structure, the screw structure 410 is rotatably arranged in the accommodation portion 120 about an axis thereof, the rotating structure is rotatably mounted on the lifting seat 300 (for example, mounted on the limiting block 310) about an axis thereof, the rotating structure is sleeved on the screw structure 410 and is in screw transmission connection with the screw structure 410.

[0064] Exemplarily, four screw structures 410 are respectively arranged at the four accommodation portions 120, the upper ends of the four screw structures 410 are rotatably mounted in the screw mounting holes 130 provided in the support rail 100, and the lower ends are rotatably mounted in the fixed seat 430, and the driving structure 420 of the second lifting support mechanism 400, such as a driving motor, is mounted below the fixed seat 430 and is in driving connection with the screw structure 410.

[0065] The structure of the second lifting support mechanism 400 is not limited thereto, and the screw structure 410 can be replaced by a rack without violating the design concept of the present application, and correspondingly, the rotating structure can be replaced by a gear.

[0066] In the above embodiment, optionally, the temporary support table 520 is provided with a plug-in portion 521, the lifting seat 300 is provided with a plug-in matching portion 350, and the plug-in matching portion 350 is in plug-in connection with the plug-in portion 521 in any one of the vehicle width direction and the up-down direction.

[0067] When the plug-in matching portion 350 is in plug-in connection with the plug-in portion 521 in the vehicle width direction, the plug-in portion 521 can be a plug-in groove, and the plug-in matching portion 350 can be a plug-in guide rail, the plug-in groove and the plug-in guide rail extend along the vehicle width direction, that is, along the Y-axis direction, and the cross-sectional shape thereof can be T-shaped, and the cross section is a plane parallel to the YZ plane. At this time, the temporary support table 520 needs to be disassembled from the side.

[0068] As Figure 10 It is shown that the plug-in matching portion 350 is a plug hole, Figure 12 , Figure 13It is shown that the insertion part 521 is a plug post, and both are inserted in the up-down direction.

[0069] In the above embodiment, optionally, when the lifting seat 300 is at its lower limit position, the distance between the top surface of the sliding support platform 510 and the top surface of the support rail 100 is greater than the sum of the diameter of the running wheel 831 and the distance between the bottom end of the stabilizer wheel 834 and the top surface of the support rail 100.

[0070] That is, when the lifting seat 300 is at its lower limit position, the distance between the top surface of the sliding support platform 510 and the structural low point of the bogie 830 (the bottom end of the stabilizer wheel 834) in the region corresponding to the installation gap 110 is greater than the diameter of the running wheel 831, thereby facilitating the taking and placing of the running wheel 831 on the left or right side.

[0071] As shown in Figure 4 and Figure 11 In the above embodiment, optionally, in the initial state, at least one of the lifting seat 300 and the sliding support platform 510 is used to contact the guide wheel 833 on one side of the vehicle width direction of the bogie 830, and at least one of the lifting seat 300 and the temporary support platform 520 is used to contact the guide wheel 833 on the other side of the vehicle width direction of the bogie 830. Thus, the driving stability of the vehicle 800 when passing through the installation gap 110 is ensured. As shown in Figure 11 It is shown that the lifting seat 300 is provided with a guard plate 340 at both ends of the vehicle width direction, which can contact the guide wheel 833 through the guard plate 340.

[0072] Another embodiment of the present application provides a straddle-type monorail vehicle maintenance system, which includes the running wheel dismounting device of the above embodiment.

[0073] In some scenarios, the support rail 100 of the running wheel dismounting device is configured to be docked with the rail beam of the vehicle 800, and the vehicle 800 to be maintained can be transferred onto the support rail 100 through the rail beam. Thus, the straddle-type monorail vehicle maintenance system is used to realize maintenance of the vehicle 800 at a position outside the normal driving line.

[0074] In some scenarios, the support rail 100 of the running wheel dismounting device is configured as the rail beam of the vehicle 800, thereby the straddle-type monorail vehicle maintenance system is used to realize on-track maintenance of the vehicle 800 on the normal driving line.

[0075] Another embodiment of the present application provides a dismounting method for the running wheel dismounting device as described in the above embodiment, or for the straddle-type monorail vehicle maintenance system as described in the above embodiment, the dismounting method comprising: Step S1, the top surface of the sliding support platform 510 of the traveling wheel dismounting device and the top surface of the temporary support platform 520 are respectively butted against the top surface of the support rail 100 of the traveling wheel dismounting device.

[0076] This step carries out the preparation of the traveling wheel dismounting device, ensuring that the vehicle 800 can move smoothly to the installation gap 110 through the walking of the traveling wheels 831.

[0077] Step S2, the traveling wheels 831 of the bogie 830 of the vehicle 800 travel to the installation gap 110.

[0078] At this time, the projection of the traveling wheels 831 in the up-down direction within the horizontal to the front-back direction is located in the region between the front-back edges of the installation gap 110, that is, the installation gap 110 can be used for the passing of the traveling wheels 831.

[0079] Step S3, the first lifting support mechanism 200 supports the frame 832 of the bogie 830.

[0080] Specifically, the first lifting support mechanism 200 jacks up the frame 832 of the bogie 830, and the first lifting support mechanism 200 supports the frame 832 and the vehicle body and the like supported thereby, replacing the traveling wheels 831 as the main load-bearing structure of the vehicle 800 Step S4, dismounting the temporary support platform 520.

[0081] For example, the second lifting support mechanism 400 drives the lifting seat 300, the sliding support platform 510 and the temporary support platform 520 to move downward until they move to a position suitable for dismounting the temporary support platform 520, and then dismount the temporary support platform 520.

[0082] Step S5, adjusting the position of the sliding support platform 510 to support the traveling wheels 831 to be dismounted by the sliding support platform 510.

[0083] Under the action of the second lifting support mechanism 400, the lifting seat 300 and the sliding support platform 510 can be lifted to form support for a certain traveling wheel 831, for example, the first wheel 831A.

[0084] Step S6, dismounting the fixing bolts of the traveling wheels 831, and adjusting the position of the sliding support platform 510 so that the traveling wheels 831 are disengaged from their installation positions.

[0085] Specifically, the dismounting of the fixing structure of the first wheel 831A is carried out, and then the sliding support platform 510 can drive the first wheel 831A carried thereby to move in the vehicle width direction away from the second wheel 831B, so that the first wheel 831A is disengaged from its installation position.

[0086] Step S7, adjusting the sliding support table 510 to the taking-off position of the traveling wheel 831, and taking off the traveling wheel 831.

[0087] Specifically, the second lifting support mechanism 400 drives the lifting seat 300, the sliding support table 510 and the traveling wheel 831 carried thereby to move downward, so that the first wheel 831A moves downward and out of the space formed by the frame 832 for accommodating the traveling wheel, and moves to a position convenient for taking out the first wheel 831A (at this time, the position of the sliding support table 510 is the taking-off position of the traveling wheel 831).

[0088] Step S8, adjusting the position of the sliding support table 510 to support the other traveling wheel 831 to be disassembled by the sliding support table 510, and continuing the disassembly of the other traveling wheel 831 until the disassembly of all the traveling wheels 831 is completed.

[0089] The installation process of the traveling wheel 831 can be opposite to the above process, which will not be described in detail here.

[0090] In the above embodiment, optionally, when the sliding support table 510 is at the taking-off position of the traveling wheel 831, the sliding support table 510 is arranged beyond the edge of the support rail 100 in the vehicle width direction, and the adjusting of the sliding support table 510 to the taking-off position of the traveling wheel 831 comprises: lowering the position of the lifting seat 300 by the second lifting support mechanism 400, and adjusting the position of the sliding support table 510 in the vehicle width direction by the sliding drive mechanism 600, so that the sliding support table 510 moves to the taking-off position.

[0091] In this way, it is convenient to take and place the traveling wheel 831 on the left side or the right side of the entire device.

[0092] In the above embodiment, optionally, the adjusting of the position of the sliding support table 510 to support the other traveling wheel 831 to be disassembled by the sliding support table 510 comprises: raising the position of the lifting seat 300 by the second lifting support mechanism 400, and adjusting the position of the sliding support table 510 in the vehicle width direction by the sliding drive mechanism 600, so that the sliding support table 510 moves below the other traveling wheel 831 to be disassembled and supports the traveling wheel 831.

[0093] For example, the second lifting support mechanism 400 drives the lifting seat 300 and the structure carried thereby to move upward, and the sliding support table 510 is adjusted in position until the sliding support table 510 supports the second wheel 831B below the second wheel 831B, for example, the second wheel 831B, and the second lifting support mechanism 400 drives the lifting seat 300 and the structure carried thereby to move downward, so that the second wheel 831B moves downward, out of the space formed by the frame 832 for accommodating the running wheel, and moves to a position convenient for removal.

[0094] In the above embodiment, when the running wheel dismounting device comprises the running wheel clamping tool 700, after the step S4 and before the step S5, the dismounting method further comprises: installing the running wheel clamping tool 700.

In some scenarios, the sliding support table 510 among the temporary support table 520 and the sliding support table 510 can be arranged close to the maintenance window 821, and when the sliding support table 510 is located at the position for removing the running wheel 831, the sliding support table 510 is located away from the temporary support table 520, so as to facilitate the quick dismounting operation of the first wheel 831A, which will not be described in detail here.

[0097] At this time, further, the adjusting of the position of the sliding support table 510 to support the running wheel 831 to be dismounted by the sliding support table 510 comprises: the adjusting of the position of the sliding support table 510 to support the running wheel 831 to be dismounted by the sliding support table 510 comprises: adjusting the position of the sliding support table 510 by the sliding drive mechanism 600 to support the running wheel 831 close to one end of the maintenance window 821 by the sliding support table 510. That is, the running wheel 831 (the first wheel 831A) close to the fixing bolt is dismounted first.

[0098] The straddle-type monorail vehicle maintenance system and dismounting method have all the beneficial effects of the running wheel dismounting device, which will not be described in detail here.
