[0111] It should also be noted that the arrangement modes of the telescopic rods 31, the first telescopic rods 7 and the second telescopic rods 8 are not limited, as long as the support strength can be satisfied. For example, in some specific embodiments, such as Figure 11As shown in the figure, in the end wall 1002 installation component, some telescopic rods 31 extend along the Z direction, with the lower end connected to the support component 1 and the upper end clamped to the top beam of the door frame on the end wall 1002; some telescopic rods 31 extend along the Y direction, with the right end connected to the support component 1 and the left end clamped to the side beam of the door frame on the end wall 1002. The remaining telescopic rods 31 are inclined, having a non-zero angle with the Z direction and the Y direction, with the right end connected to the support component 1 and the left end clamped to the side beam of the door frame on the end wall 1002. As Figure 3 shown in the figure, in the two-position side wall installation component, the two-position telescopic rod 8 is inclined, having a non-zero angle with the Z direction and the X direction, and the left end of some of the two-position telescopic rods 8 is connected to the two-position side wall 1005, and the right end is connected to the support component 1. The left end of the remaining two-position telescopic rods 8 is connected Figure 17 to the inner strut joint 92 of the false door component 9 shown in the figure, and the right end is connected to the support component 1. In the one-position side wall installation component, several one-position telescopic rods 7 and several two-position telescopic rods 8 in the two-position side wall installation component are symmetrically arranged with respect to the vehicle body center plane.

[0112] On the basis of the above embodiments, the support component 1 includes an external vehicle support component 11 and an internal vehicle support component 12; the underframe positioning component 2 is provided at the top of the external vehicle support component 11; the internal vehicle support component 12 is used to be placed on the top of the underframe 1001 and is detachably connected to the external vehicle support component 11 for connecting the end wall positioning component 3, the one-position side wall installation component, and the two-position side wall installation component.

The internal vehicle support component 12 can be fixedly connected to the external vehicle support component 11 through structures such as straps or fixed tensioners 112. Thus, the internal vehicle support component 12 can be used as a connection base to connect the telescopic rods 31 of the end wall positioning component 3, the one-position telescopic rods 7 of the one-position side wall installation component, and the two-position telescopic rods 8 of the two-position side wall installation component. With such a setting, the layout of the support component 1 is reasonable and the structure is simple, which is beneficial to improving the stability during the vehicle body assembly process.

The pressing beam 122 is pressed above the through longitudinal beam 121, and the pressing beam 122 can pass through the first side wall 1004 and the two ends of the second side wall 1005 and is used to be connected to the corresponding basic longitudinal beam 111 through the corresponding fixed tensioner 112; a number of first telescopic rods 7 and a number of second telescopic rods 8 are connected to the through longitudinal beam 121, and a number of telescopic rods 31 are connected to the pressing beam 122.

[0115] As Figure 7 shown, in the external support assembly 11, two parallel basic longitudinal beams 111 are provided at the bottommost part for supporting and installing the underframe positioning assembly 2. It should be noted that the length of the basic longitudinal beam 111 is not limited, and the center distance between the two basic longitudinal beams 111 is not limited, as long as the support requirements are met. For example, in some specific embodiments, the length of the basic longitudinal beam 111 is 24 meters, and the center distance between the two basic longitudinal beams 111 is 2.68 meters.

[0116] Furthermore, in the internal support assembly 12, a through longitudinal beam 121 extending along the Y direction and placed on the underframe 1001 is provided. The through longitudinal beam 121 can extend from one end of the underframe 1001 to the other end, and the through longitudinal beam 121 includes two side beams extending along the Y direction and connecting beams connecting between the two side beams, so as to facilitate connecting the first telescopic rods 7 for fixing the first side wall 1004 and the second telescopic rods 8 for fixing the second side wall 1005 to form a number of fulcrums, thereby fixing and supporting the first side wall 1004 and the second side wall 1005; correspondingly, a pressing beam 122 extending along the X direction is provided to be pressed above the through longitudinal beam 121 to fix the through longitudinal beam 121, and one end of the pressing beam 122 can extend to and pass through the door opening for installing the door on the first side wall 1004, and the other end can extend to and pass through the door opening for installing the door on the second side wall 1005, so as to avoid the first side wall 1004 and the second side wall 1005. While meeting the process requirements of disassembling and assembling the vehicle body, the end parts of the adjacent basic longitudinal beam 111 and the pressing beam 122 can be fixedly connected through the fixed tensioner 112, so as to facilitate connecting a number of telescopic rods 31 for fixing the end wall 1002 to form a number of fulcrums, thereby fixing and supporting the end wall 1002. With such a setting, while meeting the support strength, the structure of the support assembly 1 can be effectively simplified, the weight of the support assembly 1 can be effectively reduced, and the installation difficulty can be reduced.

[0117] It should be noted that there is no limitation on the length, material, type, etc. of the full-length longitudinal beam 121, as long as it can meet the installation requirements. For example, generally, the longitudinal beam includes two side beams with a length of 18 meters, and the two side beams are connected into one body by cross beams; or, preferably, the full-length longitudinal beam 121 includes several straight ladder-shaped longitudinal beam segments 1211 with equal lengths and several quick tensioners 1212, and the adjacent longitudinal beam segments 1211 are connected into one body by the quick tensioners 1212 at the adjacent ends; furthermore, the full-length longitudinal beam 121 can be made of aluminum profiles, or can also be made of steel profiles, etc.

It can be understood that generally the underframe 1001 is located at the bottom of the vehicle body, and in this step, the underframe 1001 is first placed in place.

[0147] Step S2: Place the in-vehicle support assembly 12 on the top of the underframe 1001 and press the in-vehicle support assembly 12 against the underframe 1001 by a fixed tensioner 112. It can be understood that the underframe 1001 is fixed by the in-vehicle support assembly 12, as Figure 7 shown, to prepare for subsequent assembly steps.

[0148] Step S3: Hoist the end wall 1002 by a crane to place the end wall 1002 at one end of the end beam of the underframe 1001, and install the end wall 1002 in place by the end wall 1002 installation assembly. It can be understood that the end wall 1002 is lifted and transported by a crane, moved to above the end beam of the underframe 1001, and then pushed down to place it on the end beam, and then the end wall 1002 is fixed by the end wall 1002 installation assembly.

[0149] Step S4: Drive the first side wall 1004 by a crane and the first side wall positioning assembly 5 to pre-assemble the first side wall 1004 in place; and drive the second side wall 1005 by a crane and the second side wall positioning assembly 6 to pre-assemble the second side wall 1005 in place. It can be understood that the first side wall 1004 is lifted and transported by a crane and the first side wall positioning assembly 5. For example, the first side wall 1004 is lifted by a crane and transported to above the fetal position, and then the first side wall positioning assembly 5 is started to cooperate with the crane to receive the first side wall 1004, and then the first side wall positioning assembly 5 drives the first side wall 1004 to move to a preset position and place it at a preset position above the underframe 1001, as Figure 12 and Figure 13 shown, to complete the pre-assembly of the first side wall 1004; similarly, the second side wall 1005 is lifted and transported by a crane and the second side wall positioning assembly 6. For example, the second side wall 1005 is lifted by a crane and transported to above the fetal position, and then the second side wall positioning assembly 6 is started to cooperate with the crane to receive the second side wall 1005, and then the second side wall positioning assembly 6 drives the second side wall 1005 to move to a preset position and place it at a preset position above the underframe 1001, as Figure 12 and Figure 13 shown, to complete the pre-assembly of the second side wall 1005.

[0150] Step S5: Drive the roof 1003 by the overhead crane and the roof positioning component 4 to pre-assemble the roof 1003 in place; it can be understood that the overhead crane and the roof positioning component 4 are used to lift and transfer the roof 1003. For example, the roof 1003 is lifted by the overhead crane and transferred above the fetal position, and then the roof positioning component 4 is started to cooperate with the overhead crane to receive the roof 1003, and then moved to the preset position by the roof positioning component 4 and placed at the preset position above the first side wall 1004 and the second side wall 1005, as Figure 2 shown to complete the pre-assembly of the roof 1003.

[0151] Step S6: Drive the roof 1003 to move along the first preset path by the roof positioning component 4 to take the roof 1003 away from the first side wall 1004 and the second side wall 1005; it can be understood that after the positioning of the first side wall 1004 and the second side wall 1005 is completed in step S4 and the positioning of the roof 1003 is completed in step S5, the disassembly is carried out in the reverse order of the pre-assembly. In this step, the roof 1003 is disassembled first, and the roof positioning component 4 is used to lift the roof 1003 and drive the roof 1003 to move along the first preset path. For example, the roof 1003 is vertically lifted 330 mm along the Z direction and other preset distances.

[0152] Step S7: Drive the first side wall 1004 to move along the second preset path by the first side wall positioning component 5 to take the first side wall 1004 away from the underframe 1001 and the end wall 1002; and drive the second side wall 1005 to move along the third preset path by the second side wall positioning component 6 to take the second side wall 1005 away from the underframe 1001 and the end wall 1002; it can be understood that in this step, the first side wall 1004 and the second side wall 1005 are disassembled. The first side wall positioning component 5 is used to lift the first side wall 1004 and drive the first side wall 1004 to move along the second preset path. For example, the first side wall 1004 is first retracted 100 mm along the X direction toward the side away from the underframe 1001, and then the first side wall 1004 is vertically lifted 220 mm along the Z direction; similarly, the second side wall positioning component 6 is used to lift the second side wall 1005 and drive the second side wall 1005 to move along the third preset path. For example, the second side wall 1005 is first retracted 100 mm along the X direction toward the side away from the underframe 1001, and then the second side wall 1005 is vertically lifted 220 mm along the Z direction.

[0153] Step S8: Apply sealant to the lower side beams of the first side wall 1004, the lower side beams of the second side wall 1005, and the side beams of the underframe 1001. Then, drive the first side wall 1004 to move along the second preset path through the first side wall positioning assembly 5 to reinstall the first side wall 1004 in place; and drive the second side wall 1005 to move along the third preset path through the second side wall positioning assembly 6 to reinstall the second side wall 1005 in place. It can be understood that sealant is applied to the disassembled first side wall 1004 and second side wall 1005. Correspondingly, sealant is applied to the first side beam of the underframe 1001 that abuts and cooperates with the first side wall 1004 and the second side beam that abuts and cooperates with the second side wall 1005. Then, under the control of the controller, drive the first side wall 1004 to be installed on the underframe 1001 along the reverse of the second preset path through the first side wall positioning assembly 5, and drive the second side wall 1005 to be installed on the underframe 1001 along the reverse of the third preset path through the second side wall positioning assembly 6. For example, first drive the side wall to vertically drop 220 mm in the Z direction, and then drive the side wall to advance 100 mm in the X direction towards the side close to the underframe 1001.

[0154] Step S9: Apply sealant to the upper side beams of the first side wall 1004, the upper side beams of the second side wall 1005, and the side beams of the car body roof 1003. Then, drive the car body roof 1003 to move along the first preset path through the car body roof positioning assembly 4 to reinstall the car body roof 1003 in place; It can be understood that sealant is applied to the disassembled car body roof 1003. Correspondingly, sealant is applied to the upper surfaces of the first side wall 1004 and the second side wall 1005 that abut and cooperate with the car body roof 1003. Then, under the control of the controller, drive the car body roof 1003 to be installed on the first side wall 1004 and the second side wall 1005 along the reverse of the first preset path through the car body roof positioning assembly 4.

[0155] Step S10: After the sealant is completely cured, use blind rivets to fixedly connect the car body roof 1003, the underframe 1001 and the first side wall 1004; the car body roof 1003, the underframe 1001 and the second side wall 1005; the end wall 1002 and the underframe 1001, the car body roof 1003, the first side wall 1004, the second side wall 1005. It can be understood that after the sealant is cured, adjacent components in the car body are fixedly connected by blind rivets to complete the secondary synthesis of the car body.

[0156] On the basis of the above embodiments, after step S10, it further includes:

[0157] Step S11: Loosen the limiting structure between the false door assembly 9 and the side wall to which it is connected.

[0158] Then, several one-side wall positioning components 5 drive the corresponding false door components 9 arranged on the one-side wall 1004 to move to the first false door removal position. Then, the output end of the one-side wall positioning component 5 is disengaged from the external positioning joint 93 of the corresponding false door component 9. Then, the overhead crane is used to lift the corresponding false door component 9 away from the output end of the corresponding one-side wall positioning component 5 and drive it to the one-end out-of-position station.

[0159] Alternatively, several two-side wall positioning components 6 drive the corresponding false door components 9 arranged on the two-side wall 1005 to move to the second false door removal position. Then, the output end of the two-side wall positioning component 6 is disengaged from the external positioning joint 93 of the corresponding false door component 9. Then, the overhead crane is used to lift the corresponding false door component 9 away from the output end of the corresponding two-side wall positioning component 6 and drive it to the one-end out-of-position station.

[0160] It can be understood that the limiting structure that fixes the false door component 9 on the side wall is loosened first. Then, each one-side wall positioning component 5 is started to drag each group of false door components 9 out of the corresponding door openings by using each one-side wall positioning component 5. After the overhead crane lifts the false door component 9, the output end of the one-side wall positioning component 5 is separated from the external positioning joint 93 on the false door component 9. Furthermore, each group of false door components 9 arranged on the one-side wall 1004 can be lifted by the overhead crane to drive each group of false door components 9 arranged on the one-side wall 1004 to the one-end out-of-position station. Similarly, each two-side wall positioning component 6 is started to drag each group of false door components 9 out of the corresponding door openings by using each two-side wall positioning component 6. After the overhead crane lifts the false door component 9, the output end of the one-side wall positioning component 5 is separated from the external positioning joint 93 on the false door component 9. Furthermore, each group of false door components 9 arranged on the two-side wall 1005 can be lifted by the overhead crane to drive each group of false door components 9 arranged on the two-side wall 1005 to the one-end out-of-position station.

[0161] It should be noted that the specific steps for separating the output end of the side wall positioning component from the external positioning joint 93 on the false door component 9 are not limited. For example, in some specific embodiments, the output end of the side wall positioning component uses a chuck 57 with the above-mentioned locking pressing plate. First, the bolt is loosened to loosen the locking pressing plate of the chuck 57. Then, after the controller obtains the instruction for the false door component 9 to disengage from the chuck 57, the side wall positioning component is controlled to vertically descend a preset distance along the Z direction so that the chuck 57 is disengaged from the external positioning joint 93.

[0162] Preferably, in some specific embodiments, the controller numbers each group of false door assemblies 9, each one-position column 13, and each two-position column 14. When it is necessary to disassemble each group of false door assemblies 9 provided on the one-position side wall 1004, enter the "disassemble false doors on the one-position side wall 1004" interface of the controller, and the controller inputs the number of the two-position column 14 to disassemble the false door assembly 9 through the overhead crane and the side wall positioning assembly on this column; similarly, when it is necessary to disassemble each group of false door assemblies 9 provided on the two-position side wall 1005, enter the "disassemble false doors on the two-position side wall 1005" interface of the controller, and the controller inputs the number of the two-position column 14 to disassemble the false door assembly 9 through the overhead crane and the side wall positioning assembly on this column.

[0163] Step S12: Loosen the fixed compressor, and then extract the full-length longitudinal beam 121; it can be understood that after all the false door assemblies 9 are disassembled, first loosen the fixed compressor that fixes the full-length longitudinal beam 121, and then extract the full-length longitudinal beam 121 through the door openings at both ends of the vehicle body.

[0164] Step S13: Install a support beam at the output ends of the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6. Drive the support beam to rise through the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 until it abuts against the internal support frame 102. Then disassemble the connection structure between the connection frame 103 and the internal support frame 102. Then lift the external lifting frame 101 away through the overhead crane and the roof positioning assembly 4, and drive the support beam and the internal support frame 102 to descend onto the chassis 1001 through the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6, and then extract the internal support frame 102.

[0165] It can be understood that after the full-length longitudinal beam 121 is disassembled, first pass several support beams through the opposite door openings of the oppositely arranged side walls. The support beams can adopt beam structures such as straight-line type or straight-ladder type. Then fix the two ends of the support beam at the output ends of the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6. Then start the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 to drive the support beam to rise vertically to lift the internal support frame 102 and prevent the internal support frame 102 from falling due to loss of force; on this basis, first loosen the connection structure between the connection frame 103 and the internal support frame 102, and then disassemble the integrated structures of the internal support frame 102, the external lifting frame 101, and the connection frame 103 separately. Specifically, for the internal support frame 102, start the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 to drive the support beam and the internal support frame 102 placed thereon to descend vertically onto the chassis 1001, and then extract the internal support frame 102 through the door openings at both ends of the vehicle body; for the integrated structure of the external lifting frame 101 and the connection frame 103, start the overhead crane to lift it vertically, and then take it away and move it to a preset position.

[0166] Based on the above embodiments, the overhead crane and the first side wall positioning assembly 5 are used to drive the first side wall 1004 to pre-assemble the first side wall 1004 in place, including:

[0167] Obtain the instruction to receive the first side wall 1004, so as to control the overhead crane to lift and transfer the first side wall 1004 to vertically descend along the Z direction, so that the external positioning joint 93 in the false door assembly 9 is in driving fit with the first side wall positioning assembly 5; it can be understood that first, the first side wall 1004 is lifted by the overhead crane, so that the external positioning joint 93 of the false door assembly 9 provided on the first side wall 1004 is connected to the first side wall positioning assembly 5. For example, the external positioning joint 93 on the false door assembly 9 falls into the opened chuck 57, and the locking pressure plate of the chuck 57 is rotated to fall into the positioning groove of the external positioning joint 93, and then the locking pressure plate is fixed by bolts, and then the first side wall 1004 can be driven to move by the first side wall positioning assembly 5.

[0168] Obtain the instruction to move to the working position of the first side wall 1004, so as to control the first side wall positioning assembly 5 to transfer the first side wall 1004 to the working position of the first side wall 1004; it can be understood that first, the first side wall 1004 is driven to move to the working position of the first side wall 1004 to prepare for further precisely adjusting the position of the first side wall 1004 so that the first side wall 1004 is pre-assembled on the chassis 1001. For example, there is a first assembly distance of 10 mm in both the Y direction and the Z direction between the first side wall 1004 at the working position of the first side wall 1004 and the preset assembly position with the chassis 1001.

[0169] Obtain the first assembly distance, so as to control the first side wall positioning assembly 5 to transfer the first side wall 1004 to the pre-assembly position of the first side wall 1004; it can be understood that according to the first assembly distance between the current working position of the first side wall 1004 and the pre-assembly position of the first side wall 1004, the movement of the first side wall positioning assembly 5 is controlled to drive the first side wall 1004 to move so that it moves to the pre-assembly position of the first side wall 1004. For example, the actual value of the distance between the side beam of the first side wall 1004 and the side beam of the chassis 1001 is measured manually, and the coordinate value is input on the controller to make the first side wall 1004 move to fit the chassis 1001.

[0170] Obtain the actual working position of the first side wall 1004 and record the actual working position of the first side wall 1004; it can be understood that when pre-assembling the first side wall 1004, the current coordinates of the first side wall 1004, that is, the actual working position of the first side wall 1004, are obtained and recorded, so as to drive the first side wall 1004 to accurately reset during secondary synthesis.

[0171] Similarly, on the basis of the above embodiments, the overhead crane and the two-position side wall positioning assembly 6 are used to drive the two-position side wall 1005 to pre-assemble the two-position side wall 1005 in place, including:

[0172] Obtain the instruction to connect the two-position side wall 1005, so as to control the overhead crane to lift and transfer the two-position side wall 1005 to vertically descend along the Z direction, so that the external positioning joint 93 in the false door assembly 9 is in driving cooperation with the two-position side wall positioning assembly 6; it can be understood that first, the two-position side wall 1005 is lifted by the overhead crane, so that the external positioning joint 93 of the false door assembly 9 provided on the two-position side wall 1005 is connected to the two-position side wall positioning assembly 6. For example, the external positioning joint 93 on the false door assembly 9 falls into the open collet 57, and the locking pressure plate of the collet 57 is rotated to fall into the positioning groove of the external positioning joint 93, and then the locking pressure plate is fixed with bolts. Furthermore, the two-position side wall 1005 can be driven to move by the two-position side wall positioning assembly 6.

[0173] Obtain the instruction to move to the working position of the two-position side wall 1005, so as to control the two-position side wall positioning assembly 6 to transfer the two-position side wall 1005 to the working position of the two-position side wall 1005; it can be understood that first, the two-position side wall 1005 is driven to move to the working position of the two-position side wall 1005 to prepare for further precisely adjusting the position of the two-position side wall 1005 so that the two-position side wall 1005 is pre-assembled on the chassis 1001. For example, there is a two-position assembly distance of 10 mm along the Y direction and the Z direction between the two-position side wall 1005 at the working position of the two-position side wall 1005 and the preset assembly position with the chassis 1001.

[0174] Obtain the two-position assembly distance, so as to control the two-position side wall positioning assembly 6 to transfer the two-position side wall 1005 to the pre-assembly position of the two-position side wall 1005; it can be understood that according to the two-position assembly distance between the current working position of the two-position side wall 1005 and the pre-assembly position of the two-position side wall 1005, the movement of the two-position side wall positioning assembly 6 is controlled to drive the two-position side wall 1005 to move so that it moves to the pre-assembly position of the two-position side wall 1005. For example, manually measure the actual value of the distance between the side beam of the two-position side wall 1005 and the side beam of the chassis 1001, input the coordinate value on the controller, and make the two-position side wall 1005 move to fit the chassis 1001.

[0175] Obtain the actual working position of the two-position side wall 1005 and record the actual working position of the two-position side wall 1005; it can be understood that when pre-assembling the two-position side wall 1005, obtain and record the current coordinates of the two-position side wall 1005, that is, the actual working position of the two-position side wall 1005, so as to accurately reset the two-position side wall 1005 during secondary synthesis.

[0176] On the basis of the above-mentioned embodiment, the roof 1003 is driven by the overhead crane and the roof positioning assembly 4 to pre-assemble the roof 1003 in place, including: obtaining an instruction to connect the roof 1003 to control the overhead crane to drive the roof 1003 to descend vertically along the Z direction, so that the first transmission joint 1011 is transmitted and matched with the second transmission joint 44; it can be understood that the roof 1003 is first hoisted by the overhead crane, so that the first transmission joint 1011 of the roof accompanying transfer assembly 10 fixedly connected to the roof 1003 is connected to the second transmission joint 44 at the output end of the roof positioning assembly 4, for example, when the second transmission joint 44 is used, when the pin hole on the first transmission joint 1011 is aligned with the second transmission joint 44 on the roof positioning assembly 4, the overhead crane hoists the roof 1003 to fall, so that the second transmission joint 44 is inserted into the pin hole of the first transmission joint 1011.

[0177] Obtain an instruction to move to the roof 1003 working position to control the roof positioning assembly 4 to transfer the roof 1003 to the roof 1003 working position; it can be understood that the roof 1003 is first driven to move to the roof 1003 working position to prepare for further precise adjustment of the position of the roof 1003 so that the roof 1003 is pre-assembled onto the first side wall 1004 and the second side wall 1005. For example, the roof 1003 at the roof 1003 working position has a roof 1003 assembly distance of 10 mm along the Z direction between the preset assembly position with the first side wall 1004 and the second side wall 1005.

[0178] The assembly distance of the roof 1003 is obtained to control the roof positioning component 4 to transfer the roof 1003 to the pre-assembly position of the roof 1003; it can be understood that according to the assembly distance of the roof 1003 between the current working position of the roof 1003 and the pre-assembly position of the roof 1003, the movement of the roof positioning component 4 is controlled to drive the roof 1003 to move and move it to the pre-assembly position of the roof 1003. For example, the actual value of the distance between the side beam of the roof 1003 and the side beam of the first side wall 1004 is manually measured, and the coordinate value is input on the controller to move the roof 1003 to fit the first side wall 1004 and the second side wall 1005.

[0179] The actual working position of the roof 1003 is obtained and recorded; it is understandable that when the pre-assembly of the roof 1003 is realized, the current coordinates of the roof 1003, that is, the actual working position of the roof 1003, are obtained and recorded, so that the roof 1003 can be accurately reset during the secondary synthesis.

For example, click the "Roof 1003 Disassembly" option on the controller display screen to start the specific operation of disassembling the roof 1003 according to this instruction.

[0181] Based on the above embodiments, the first side wall positioning component 5 drives the first side wall 1004 to move along a second preset path to move the first side wall 1004 away from the underframe 1001 and the end wall 1002, including: obtaining a first side wall 1004 disassembly instruction to control the first side wall positioning component 5 to drive the first side wall 1004 to move along the second preset path; that is, the controller needs to first receive an externally input first side wall 1004 disassembly instruction. For example, click the "First Side Wall 1004 Disassembly" option on the controller display screen to start the specific operation of disassembling the first side wall 1004 according to this instruction.

[0182] Similarly, based on the above embodiments, the second side wall positioning component 6 drives the second side wall 1005 to move along a third preset path to move the second side wall 1005 away from the underframe 1001 and the end wall 1002, including: obtaining a second side wall 1005 disassembly instruction to control the second side wall positioning component 6 to drive the second side wall 1005 to move along the second preset path; that is, the controller needs to first receive an externally input second side wall 1005 disassembly instruction. For example, click the "Second Side Wall 1005 Disassembly" option on the controller display screen to start the specific operation of disassembling the second side wall 1005 according to this instruction.

For example, click the "First Side Wall 1004 Secondary Assembly" option on the controller display screen to make the first side wall 1004 move back to the above actual working position of the first side wall 1004 again.

[0184] Similarly, on the basis of the above embodiments, the two-position side wall positioning assembly 6 is used to drive the two-position side wall 1005 to move along the third preset path to reinstall the two-position side wall 1005 in place, including: obtaining the reinstallation instruction for the two-position side wall 1005 to control the two-position side wall positioning assembly 6 to drive the two-position side wall 1005 to move along the second preset path so that the two-position side wall 1005 is reinstalled in place; that is, the controller needs to first receive the externally input reinstallation instruction for the two-position side wall 1005. For example, click the "Second assembly of the two-position side wall 1005" option on the controller display screen to make the two-position side wall 1005 move back to the actual working position of the two-position side wall 1005 again.

[0185] On the basis of the above embodiments, then the roof positioning assembly 4 is used to drive the roof 1003 to move along the first preset path to reinstall the roof 1003 in place, including: obtaining the reinstallation instruction for the roof 1003 to control the roof positioning assembly 4 to drive the roof 1003 to move along the second preset path so that the roof 1003 is reinstalled in place; that is, the controller needs to first receive the externally input reinstallation instruction for the roof 1003. For example, click the "Second assembly of the roof 1003" option on the controller display screen to make the roof 1003 move back to the actual working position of the roof 1003 again.

[0186] On the basis of the above embodiments, before installing the supporting beam at the output ends of the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6, it further includes: obtaining the instruction for installing the supporting beam to control the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 to move to the supporting beam installation position; it can be understood that it is necessary to adjust the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 to move to appropriate positions to facilitate the manual installation of the supporting beam.

[0187] On the basis of the above embodiments, the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 are used to drive the supporting beam to rise until it abuts against the internal support frame 102, including: obtaining the instruction for abutting against the internal support frame 102 to control the one-position side wall positioning assembly 5 and the two-position side wall positioning assembly 6 to drive the supporting beam to rise until it abuts against the internal support frame 102; it can be understood that the controller needs to first receive the externally input instruction for abutting against the internal support frame 102.
