[0052] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0053] like Figure 1 As shown, the embodiment of the present disclosure proposes a tunnel 1 construction work vehicle group, including a tractor 9, a lifting work vehicle 4 and an assembly work vehicle 5. The tractor 9 is arranged on the first track 2 in the tunnel 1, the lifting work vehicle 4 is arranged on the first track 2, the lifting work vehicle 4 is connected to the tractor 9, the lifting work vehicle 4 is used to establish a work platform in the tunnel 1, the assembling work vehicle 5 is arranged on the first track 2, the assembling work vehicle 5 is connected to the lifting work vehicle 4, and the assembling work vehicle 5 is used to set the casting module 6 on the inner wall of the tunnel 1.

[0054] It can be understood that, by setting up the lifting work vehicle 4, a working platform is provided for the workers, and by setting up the assembling work vehicle 5, the casting module 6 can be attached to the inner wall of the tunnel 1 through mechanized actions, thereby avoiding manual operations such as setting up scaffolding and lifting the casting module 6 by the workers, effectively improving the construction efficiency in the tunnel 1 and reducing the labor cost of construction in the tunnel 1.

[0055] Among them, since the lifting work vehicle 4 and the assembly work vehicle 5 are both arranged on the first track 2 and are connected to the tractor 9 in sequence, the lifting work vehicle 4 and the assembly work vehicle 5 can quickly leave the tunnel 1 under the traction of the tractor 9 after the construction of the tunnel 1 is completed, thereby further improving the construction efficiency in the tunnel 1, reducing the labor cost of construction in the tunnel 1, and reducing the impact of the construction of the tunnel 1 on the operation of the tunnel 1.

[0056] It should be noted that the specific type of tractor 9 can be set according to actual needs and is not limited to this. For example, the tractor 9 can be an electric locomotive, the power of the electric locomotive can be 89kW-1000kW, and the transmission of the electric locomotive can be either hydraulic or electric. When the electric locomotive uses hydraulic transmission, the hydraulic transmission can use a microcomputer system to control the driving; when the electric locomotive uses electric transmission, the electric transmission can use the catenary power supply in the tunnel 1 or a battery power supply.

[0057] The first track 2 and the second track 3 are components arranged on the ground of the tunnel 1 for driving. The length directions of the first track 2 and the second track 3 are both located in the axial direction of the tunnel 1, and the first track 2 and the second track 3 are arranged adjacent to each other.

[0058] A parking lot connected to the tunnel 1 should be set up near the tunnel 1. After the construction of the tunnel 1 is completed, the tractor 9 tows the lifting vehicle 4 and the assembly vehicle 5 into the parking lot connected to the tunnel 1 to reduce the impact of the tunnel 1 construction on the operation of the tunnel 1.

[0059] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the lifting work vehicle 4 includes a first flat car 405, a second flat car 406, a first lifting platform 401, a second lifting platform 402 and a crane 403. The first flat car 405 is arranged on the first track 2, the first flat car 405 is connected to the tractor 9, the second flat car 406 is arranged on the first track 2, the second flat car 406 is connected to the first flat car 405, the assembly work vehicle 5 is connected to the second flat car 406, the first lifting platform 401 is movably arranged on the first flat car 405, the second lifting platform 402 is fixedly arranged on the second flat car 406, and the crane 403 is arranged on the first flat car 405. The crane 403 is used to lift the first lifting platform 401 to the second track 3 on the side of the first track 2 in the tunnel 1.

[0060] It can be understood that the first lifting platform 401 and the second lifting platform 402 can both provide working platforms for the workers, thereby avoiding the workers from setting up scaffolding and other supporting devices, effectively improving the construction efficiency in the tunnel 1, and effectively reducing the labor cost of construction in the tunnel 1; at the same time, after the crane 403 hoisted the first lifting platform 401 onto the second track 3, the first lifting platform 401 and the second lifting platform 402 can simultaneously provide working platforms for the workers, and since the first lifting platform 401 and the second lifting platform 402 both have lifting functions, the construction in the tunnel 1 can achieve full-floor operation, thereby improving the construction efficiency in the tunnel 1 and reducing the labor cost of construction in the tunnel 1.

[0061] Among them, since the first lifting platform 401 can be set on the first flat car 405 through the lifting of the crane 403, and the second lifting platform 402 is fixedly set on the second flat car 406, after the first lifting platform 401 and the second lifting platform 402 are used, they can quickly leave the tunnel 1 under the traction of the tractor 9, thereby further improving the construction efficiency in the tunnel 1, reducing the labor cost of the construction in the tunnel 1, and reducing the impact of the construction of the tunnel 1 on the operation of the tunnel 1.

[0062] It should be noted that full-chamber operation means that workers can work at any position in the cross section of the tunnel 1.

[0063] The generator, air compressor, pump station and other equipment used by the tunnel 1 construction work group can be set on the second flat car 406.

[0064] like Figure 3 As shown, in some embodiments, the lifting work vehicle 4 also includes a third track 407, the third track 407 is arranged on the first flat car 405, the first lifting platform 401 includes a moving seat 4011, a first scissors-type lifting component 4012, a first working platform 4013 and a plurality of walking wheels 4014, the first scissors-type lifting component 4012 is arranged on the moving seat 4011, the first working platform 4013 is arranged on the lifting end of the first scissors-type lifting component 4012, the walking wheel 4014 is rotatably arranged at the bottom of the moving seat 4011, and the walking wheel 4014 is rollingly connected to the third track 407 or rollingly connected to the second track 3.

[0065] It can be understood that when the first lifting platform 401 is not in use, the moving seat 4011 is set on the third track 407 through the walking wheels 4014 to facilitate position adjustment and positioning. When the first lifting platform 401 is in use, the crane 403 hoisted the first lifting platform 401 to the second track 3. At this time, the moving seat 4011 is set on the second track 3 through the walking wheels 4014 to facilitate position adjustment and positioning, and the first working platform 4013 can be adjusted in height through the first scissors-type lifting assembly 4012. As a result, the operating personnel can flexibly adjust their working position when on the first working platform 4013, so that the construction efficiency in the tunnel 1 is higher and the labor cost is lower.

[0066] It should be noted that the specific type of the third track 407 can be set according to actual needs and is not limited to this. For example, the third track 407 has the same structure as the first track 2 and the second track 3, and the length direction of the third track 407 is parallel to the length directions of the first track 2 and the second track 3. In particular, a groove can be provided on the supporting plate of the first flat car 405, and the third track 407 is disposed in the groove to keep the surface of the supporting plate of the first flat car 405 flush, while making the installation of the first lifting platform 401 on the first flat car 405 more stable.

[0067] The number of the running wheels 4014 can be set according to actual needs and is not limited thereto. For example, there can be four running wheels 4014 , which are symmetrically arranged on both sides of the moving base 4011 .

[0068] In some embodiments, the first lifting platform 401 further includes a twelfth driving member, which is disposed on the movable base 4011 and is in driving connection with the travel wheels 4014. It is understood that the drive of the twelfth driving member enables the travel wheels 4014 to rotate, thereby enabling the first lifting platform 401 to move on its own, thereby facilitating the movement and positioning of the first lifting platform 401 and making the use of the first lifting platform 401 more convenient.

[0069] Among them, the specific type of the twelfth driving member can be set according to actual needs and is not limited to this. For example, the twelfth driving member can be a hydraulic motor, and the output shaft of the hydraulic motor is connected to the axle of the walking wheel 4014, thereby realizing the rotation of the walking wheel 4014 under the drive of the hydraulic motor; the twelfth driving member can be a driving motor and a reducer, the driving motor is arranged on the moving seat 4011, the reducer is arranged on the moving seat 4011, the output shaft of the driving motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the axle of the walking wheel 4014, thereby realizing the rotation of the walking wheel 4014 under the drive of the driving motor.

[0070] like Figure 1and Figure 2 As shown, in some embodiments, the first lifting platform 401 further includes a first lifting ring 4015 , which is disposed on the first working platform 4013 , and the crane 403 includes a first lifting hook 4039 , which cooperates with the first lifting ring 4015 .

[0071] It can be understood that when the first hook 4039 is hooked on the first lifting ring 4015, the crane 403 lifts the first lifting platform 401, and when the first hook 4039 is away from the first lifting ring 4015, the first lifting platform 401 can be operated and stored. Among them, through the cooperation of the first hook 4039 and the first lifting ring 4015, not only can the stable lifting of the first lifting platform 401 by the crane 403 be guaranteed, but also the disassembly and assembly are simple and convenient, which effectively improves the construction efficiency in tunnel 1 and reduces the labor cost of construction in tunnel 1.

[0072] It should be noted that in order to make the lifting of the first lifting platform 401 by the crane 403 more stable, multiple first lifting rings 4015 can be set on the first working platform 4013. The multiple first lifting rings 4015 are connected by steel wire ropes, and the first hook 4039 is connected to the steel wire rope. Therefore, through the setting of multiple first lifting rings 4015, the overall force on the first lifting platform 401 is made more uniform, thereby ensuring the stable lifting of the first lifting platform 401 by the crane 403.

[0073] The specific type of the crane 403 can be set according to actual needs and is not limited to this. For example, the crane 403 includes a seventh seat body 4031, a seventh swivel seat 4032, a thirteenth driving member 4033, a boom 4034, a small arm 4035, a fourteenth driving member 4036, a third telescopic arm 4037, a winch 4038 and a first hook 4039. The seventh seat body 4031 is set on the first flat car 405, the seventh swivel seat 4032 is rotatably set on the seventh seat body 4031, and the rotation direction of the seventh swivel seat 4032 is perpendicular to the first flat car 405, the thirteenth driving member 4033 is set on the seventh seat body 4031, and the thirteenth driving member 4033 is transmission-connected to the seventh swivel seat 4032, and the boom 4034 is set on the seventh swivel seat 4032 On the upper part, the forearm 4035 is hinged to the upper arm 4034, and the rotation direction of the forearm 4035 is perpendicular to the rotation direction of the seventh swivel seat 4032, the fourteenth driving member 4036 is arranged on the seventh swivel seat 4032, and the fourteenth driving member 4036 is connected to the forearm 4035 by transmission, the third telescopic arm 4037 is arranged on the forearm 4035, the winch 4038 is arranged on the telescopic end of the third telescopic arm 4037, and the first hook 4039 is arranged on the winding rope of the winch 4038. Therefore, under the drive of the thirteenth driving member 4033, the drive of the fourteenth driving member 4036, the action of the third telescopic arm 4037 and the action of the winch 4038, the overall position adjustment and angle adjustment of the first hook 4039 are realized, and then the lifting of the first lifting platform 401 is realized.

[0074] Among them, the arrangement of the seventh rotating seat 4032 on the seventh seat body 4031 can be set according to actual needs and is not limited to this. For example, a rotating bearing is set on the seventh rotating seat 4032, and the seventh seat body 4031 is set on the inner ring of the rotating bearing.

[0075] The specific type of the thirteenth driving member 4033 can be set according to actual needs and is not limited to this. For example, the thirteenth driving member 4033 can be a hydraulic motor, and gears are provided on the output shaft of the hydraulic motor and the seventh seat body 4031. The two gears are engaged, thereby realizing the rotation of the seventh rotating seat 4032 under the drive of the hydraulic motor.

[0076] The specific type of the fourteenth driving member 4036 can be set according to actual needs and is not limited to this. For example, the fourteenth driving member 4036 can be a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged to the seventh swivel seat 4032, and the piston rod end of the hydraulic cylinder is hinged to the small arm 4035, thereby realizing the rotation of the small arm 4035 under the drive of the hydraulic cylinder.

[0077] The specific type of winch 4038 can be set according to actual needs and is not limited to this.

[0078] like Figure 1 As shown, in some embodiments, the second lifting platform 402 includes a fixed seat 4021, a second scissors-type lifting assembly 4022 and a second working platform 4023, the fixed seat 4021 is set on the second flat car 406, the second scissors-type lifting assembly 4022 is set on the fixed seat 4021, and the second working platform 4023 is set on the lifting end of the second scissors-type lifting assembly 4022.

[0079] It can be understood that the second working platform 4023 is height-adjusted by the second scissor-type lifting assembly 4022, which is not only convenient for storage on the second flat car 406, but also enables the working position of the operator to be flexibly adjusted, thereby making the construction efficiency in the tunnel 1 higher and the labor cost lower.

[0080] It should be noted that the arrangement of the fixing seat 4021 on the second flat car 406 can be set according to actual needs and is not limited to this. For example, the fixing seat 4021 can be set on the second flat car 406 by welding, bolting, etc.

[0081] The specific types of the first scissors-type lifting assembly 4012 and the second scissors-type lifting assembly 4022 can be set according to actual needs and are not limited to this. For example, the first scissors-type lifting assembly 4012 and the second scissors-type lifting assembly 4022 have the same structure. Taking the first scissors-type lifting assembly 4012 as an example, the first scissors-type lifting assembly 4012 includes multiple groups of cross frames and a fifteenth driving member. The multiple groups of cross frames are sequentially arranged between the first working platform 4013 and the moving seat 4011, and the adjacent cross frames are hinged. One end of the cross frame at the top is rollingly connected to the first working platform 4013, and one end of the cross frame at the bottom is rollingly connected to the moving seat 4011. The fifteenth driving member is arranged on the moving seat 4011, and the fifteenth driving member is transmission-connected to the cross frame at the bottom. Thus, under the drive of the fifteenth driving member, the lifting and lowering of the first working platform 4013 is realized.

[0082] Among them, the specific type of the fifteenth driving member can be set according to actual needs and is not limited to this. For example, the fifteenth driving member can be a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged on the movable seat 4011, and the piston rod end of the hydraulic cylinder is hinged on one end of the bottom cross frame, thereby realizing the movement of the first working platform 4013 under the drive of the hydraulic cylinder.

[0083] The positioning of the first lifting platform 401 on the first flat car 405 can be set according to actual needs and is not limited to this. For example, the first lifting platform 401 is fixed to the first flat car 405 by multiple bolts, but this method is too cumbersome to operate.

[0084] like Figure 4 As shown, in some embodiments, the lifting work vehicle 4 also includes a plurality of fixing devices 404, the fixing devices 404 include a first cable 4041, a second cable 4042 and a tensioning assembly 4043, one end of the first cable 4041 is detachably connected to the first flat car 405, one end of the second cable 4042 is detachably connected to the first lifting platform 401, one end of the tensioning assembly 4043 is connected to an end of the first cable 4041 away from the first flat car 405, and the other end of the tensioning assembly 4043 is connected to an end of the second cable 4042 away from the first lifting platform 401.

[0085] It can be understood that the action of the tensioning assembly 4043 tensions the first cable 4041 and the second cable 4042, and with the cooperation of the plurality of fixing devices 404, the first lifting platform 401 is fixed to the first flat car 405. Simultaneously, the action of the tensioning assembly 4043 loosens the first cable 4041 and the second cable 4042. Since the first cable 4041 is detachable from the first flat car 405 and the second cable 4042 is detachable from the first lifting platform 401, the first lifting platform 401 is released from the first flat car 405. Thus, the arrangement of the tensioning assembly 4043, the first cable 4041, and the second cable 4042 makes the positioning and release of the first lifting platform 401 on the first flat car 405 more flexible and the operation more convenient, further improving the construction efficiency in the tunnel 1 and reducing the labor cost of the construction in the tunnel 1.

[0086] Among them, the detachable structure of the first cable 4041 on the first flat cart 405 and the detachable structure of the second cable 4042 on the first lifting platform 401 can be set according to actual needs, and there is no limitation to this. For example, the detachable structure of the first cable 4041 on the first flat cart 405 and the detachable structure of the second cable 4042 on the first lifting platform 401 are the same. Taking the area between the first cable 4041 and the first flat cart 405 as an example, a hook is provided on the end of the first cable 4041 away from the tensioning assembly 4043 and on the first flat cart 405, and the two hooks are connected by the hook.

[0087] The specific types of the first cable 4041 and the second cable 4042 can be set according to actual needs and are not limited thereto. For example, the first cable 4041 and the second cable 4042 can be steel cables.

[0088] like Figure 4As shown, in some embodiments, the tensioning assembly 4043 includes a cylinder 40431, a first inner rod 40432, and a second inner rod 40433. One end of the first inner rod 40432 is connected to the end of the first cable 4041 away from the first flat car 405, and the other end of the first inner rod 40432 is threadedly connected to one end of the cylinder 40431. One end of the second inner rod 40433 is connected to the end of the second cable 4042 away from the first lifting platform 401, and the other end of the second inner rod 40433 is threadedly connected to the other end of the cylinder 40431. It can be understood that the relative movement of the first inner rod 40432 and the second inner rod 40433 is achieved through the rotation of the cylinder 40431, thereby achieving the tensioning and releasing of the first cable 4041 and the second cable 4042. The operation is simple and convenient, further improving the construction efficiency in the tunnel 1 and reducing the labor cost of the construction in the tunnel 1.

[0089] Among them, the threaded connection structure between the cylinder 40431 and the first inner rod 40432 and the second inner rod 40433 can be set according to actual needs, and there is no restriction on this. For example, threaded holes are provided at both ends of the cylinder 40431, and the thread directions of the two threaded holes are opposite. The first inner rod 40432 and the second inner rod 40433 are both provided with external threads, and the external threads are respectively screwed into the internal threads of the threaded holes.

[0090] like Figure 4 As shown, in some embodiments, the tensioning assembly 4043 further includes a first nut 40434 and a second nut 40435. The first nut 40434 is threadedly sleeved on the first inner rod 40432 and abuts against an end of the cylinder 40431 adjacent to the first inner rod 40432. The second nut 40435 is threadedly sleeved on the second inner rod 40433 and abuts against an end of the cylinder 40431 adjacent to the second inner rod 40433. It is understood that by locking the first nut 40434 and the second nut 40435, the first inner rod 40432 and the second inner rod 40433 are prevented from rotating relative to the cylinder 40431, thereby ensuring stable tensioning of the first cable 4041 and the second cable 4042 by the tensioning assembly 4043, thereby further stably positioning the first lifting platform 401 on the first flat car 405.

[0091] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7As shown, in some embodiments, the assembly work vehicle 5 includes a third flat car 511, multiple rotating devices, a first telescopic arm 508 and an electromagnetic suction cup 510. The third flat car 511 is arranged on the first track 2. The third flat car 511 is connected to the lifting work vehicle 4. Multiple rotating devices are arranged on the third flat car 511 in sequence. The first telescopic arm 508 is arranged on the rotating end of the third rotating device 503, and the electromagnetic suction cup 510 is arranged on the telescopic end of the first telescopic arm 508.

[0092] It can be understood that the adsorption and release of the casting module 6 are achieved through the setting of the electromagnetic suction cup 510, and the angle and position of the electromagnetic suction cup 510 are adjusted through the action of multiple rotating devices and the first telescopic arm 508. Therefore, under the drive of the electromagnetic suction cup 510, the casting module 6 can be attached to the inner wall of the tunnel 1, effectively improving the construction efficiency in the tunnel 1 and reducing the labor cost of construction in the tunnel 1.

[0093] Among them, since multiple rotating devices, the first telescopic arm 508 and the electromagnetic suction cup 510 are all arranged on the third flat car 511, the casting module 6 can be quickly driven away from the tunnel 1 under the traction of the tractor 9 after installation, thereby further improving the construction efficiency in the tunnel 1, reducing the labor cost of construction in the tunnel 1, and reducing the impact of the construction of the tunnel 1 on the operation of the tunnel 1.

[0094] It should be noted that the electromagnetic chuck 510 is an electromagnetic clamp that uses suction generated by the chuck body when the coil is energized to hold the casting module 6. The electromagnetic chuck 510 includes an iron core, a coil, a panel, a bracket, etc. The specific type of the electromagnetic chuck 510 can be configured according to actual needs and is not limited thereto. Accordingly, the portion of the casting module 6 that is held by the electromagnetic chuck 510 should be made of a magnetic material, such as iron or steel.

[0095] like Figure 1 、 Figure 5 and Figure 7 As shown, in some embodiments, multiple rotating devices include a first rotating device 501, a second rotating device 502 and a third rotating device 503, the first rotating device 501 is arranged on the third flat car 511, the second rotating device 502 is arranged on the rotating end of the first rotating device 501, and the rotation center axis of the second rotating device 502 is perpendicular to the rotation center axis of the first rotating device 501, the third rotating device 503 is arranged on the rotating end of the second rotating device 502, the rotation center axis of the third rotating device 503 is perpendicular to the center axis of the second rotating device 502, and the first telescopic arm 508 is arranged on the rotating end of the third rotating device 503.

[0096] It can be understood that, by setting up the first rotating device 501, the second rotating device 502 and the third rotating device 503, the free rotation of the first telescopic arm 508 in three directions is realized, and in conjunction with the extension and retraction of the first telescopic arm 508 and the movement of the third flat car 511, the angle and position adjustment of the electromagnetic suction cup 510 can meet the flexible installation of the casting module 6 on the inner wall of the tunnel 1, thereby improving the construction efficiency and construction quality in the tunnel 1, and effectively reducing the labor cost of construction in the tunnel 1.

[0097] like Figure 5 As shown, in some embodiments, the first rotating device 501 includes a first base 5011, a first rotating base 5012 and a first driving member 5013. The first base 5011 is disposed on the third flat car 511. The first rotating base 5012 is rotatably disposed on the first base 5011. The central axis of the first rotating base 5012 is perpendicular to the third flat car 511. The first driving member 5013 is disposed on the first base 5011 and is transmission-connected to the first rotating base 5012.

[0098] The second rotating device 502 includes a second base 5021, a second rotating seat 5022, and a second driving member 5023. The second base 5021 is disposed on the first rotating seat 5012. The second rotating seat 5022 is rotatably disposed on the second base 5021. The rotation center axis of the second rotating seat 5022 is perpendicular to the center axis of the first rotating seat 5012. The second driving member 5023 is disposed on the second base 5021 and is in driving connection with the second rotating seat 5022.

[0099] The third rotating device 503 includes a third base body 5031, a third rotating base 5032 and a third driving member 5033. The third base body 5031 is arranged on the second rotating base 5022. The third rotating base 5032 is rotatably arranged on the third base body 5031. The rotation center axis of the third rotating base 5032 is perpendicular to the center axis of the second rotating base 5022. The first telescopic arm 508 is arranged on the third rotating base 5032. The third driving member 5033 is arranged on the third base body 5031. The third driving member 5033 is transmission-connected to the third rotating base 5032.

[0100] It can be understood that, since the first rotary seat 5012 is rotatably arranged on the first base body 5011, the first rotary seat 5012 is rotated under the drive of the first driving member 5013, the second rotary seat 5022 is rotatably arranged on the second base body 5021, the second rotary seat 5022 is rotated under the drive of the second driving member 5023, and the third rotary seat 5032 is rotatably arranged on the third base body 5031, the third rotary seat 5032 is rotated under the drive of the third driving member 5033, and the second base body 50 21 is arranged on the first rotating seat 5012, the third seat body 5031 is arranged on the second rotating seat 5022, and the first telescopic arm 508 is arranged on the third rotating seat 5032, so that under the cooperative driving of the first driving member 5013, the second driving member 5023 and the third driving member 5033, the angle of the first telescopic arm 508 can be adjusted in three directions, so that the angle of the electromagnetic suction cup 510 can meet the flexible installation of the casting module 6 on the inner wall of the tunnel 1, effectively improving the construction efficiency and construction quality in the tunnel 1, and reducing the labor cost of construction in the tunnel 1.

[0101] Among them, the rotation setting mode of the first rotating seat 5012 on the first seat body 5011, the rotation setting mode of the second rotating seat 5022 on the second seat body 5021 and the rotation setting mode of the third rotating seat 5032 on the third seat body 5031 can be set according to actual needs and are not limited to this. For example, the rotation setting mode of the first rotating seat 5012 on the first seat body 5011, the rotation setting mode of the second rotating seat 5022 on the second seat body 5021 and the rotation setting mode of the third rotating seat 5032 on the third seat body 5031 are the same. Taking the rotation setting mode of the first rotating seat 5012 on the first seat body 5011 as an example, a slewing bearing is provided on the first seat body 5011, and the first rotating seat 5012 is provided on the inner ring of the slewing bearing.

[0102] The transmission mode of the first driving member 5013 and the first rotating seat 5012, the transmission mode of the second driving member 5023 and the second rotating seat 5022, and the transmission mode of the third driving member 5033 and the third rotating seat 5032 can be set according to actual needs and are not limited to this. For example, the transmission mode of the first driving member 5013 and the first rotating seat 5012, the transmission mode of the second driving member 5023 and the second rotating seat 5022, and the transmission mode of the third driving member 5033 and the third rotating seat 5032 are the same. Taking the transmission mode of the first driving member 5013 and the first rotating seat 5012 as an example, gears are provided on the output shaft of the first driving member 5013 and the first rotating seat 5012, and the two gears are engaged, thereby realizing the rotation of the first rotating seat 5012 under the drive of the first driving member 5013. Among them, through the gear transmission method, it can adapt to the large weight of the first rotating seat 5012, the second rotating seat 5022 and the third rotating seat 5032, and ensure the stable adjustment of the angle of the electromagnetic chuck 510.

[0103] The specific types of the first driving member 5013, the second driving member 5023 and the third driving member 5033 can be set according to actual needs and are not limited to this. For example, the first driving member 5013, the second driving member 5023 and the third driving member 5033 have the same structure. Taking the first driving member 5013 as an example, the first driving member 5013 can be a hydraulic motor, and gears are provided on the output shaft of the hydraulic motor and the first rotating seat 5012. The two gears are engaged, thereby realizing the rotation of the first rotating seat 5012 under the drive of the hydraulic motor.

[0104] like Figure 1 、 Figure 5 and Figure 7 As shown, in some embodiments, the assembly vehicle 5 further includes a first movable counterweight device 515, which is disposed on the first rotating seat 5012, and the first movable counterweight device 515 and the second rotating seat 5022 are respectively located on either side of the rotation center axis of the first rotating seat 5012. It can be understood that the provision of the first movable counterweight device 515 allows the electromagnetic chuck 510 to maintain balance on the first rotating seat 5012 when the angle and position are adjusted, thereby preventing damage to the rotating structure between the first rotating seat 5012 and the first base 5011 due to uneven force, thereby ensuring stable installation of the casting module 6.

[0105] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7As shown, in some embodiments, the plurality of rotating devices further include a fourth rotating device 504 and a fifth rotating device 505, the fourth rotating device 504 being disposed on the telescopic end of the first telescopic arm 508, and the rotation center axis of the fourth rotating device 504 being parallel to the rotation center axis of the third rotating device 503;

[0106] The assembly vehicle 5 also includes a swinging device 507 and a second telescopic arm 509. The swinging device 507 is arranged on the rotating end of the fourth rotating device 504, and the rotation center axis of the swinging device 507 is perpendicular to the rotation center axis of the fourth rotating device 504. The fifth rotating device 505 is arranged at the swinging end of the swinging device 507, and the rotation center axis of the fifth rotating device 505 is perpendicular to the rotation center axis of the swinging device 507. The second telescopic arm 509 is arranged on the rotating end of the fifth rotating device 505, and the electromagnetic suction cup 510 is arranged on the telescopic end of the second telescopic arm 509.

[0107] It can be understood that, through the arrangement of the fourth rotating device 504, the fifth rotating device 505 and the swinging device 507, the electromagnetic suction cup 510 can rotate freely in three directions on the first telescopic arm 508, and cooperate with the extension and retraction of the second telescopic arm 509, so that the angle and position adjustment flexibility of the electromagnetic suction cup 510 is higher, thereby ensuring the precise installation of the casting module 6 on the inner wall of the tunnel 1, thereby improving the construction efficiency and construction quality in the tunnel 1, and effectively reducing the labor cost of construction in the tunnel 1.

[0108] At the same time, since the load-bearing weight of the fourth rotating device 504, the fifth rotating device 505, the swing device 507 and the second telescopic arm 509 is relatively small, and the load-bearing weight of the first rotating device 501, the second rotating device 502, the third rotating device 503 and the first telescopic arm 508 is relatively large, the first rotating device 501, the second rotating device 502, the third rotating device 503 and the first telescopic arm 508 can be used for coarse adjustment of the angle and position of the electromagnetic suction cup 510, and the fourth rotating device 504, the fifth rotating device 505, the swing device 507 and the second telescopic arm 509 can be used for coarse adjustment of the angle and position of the electromagnetic suction cup 510. The device 507 and the second telescopic arm 509 can be used to fine-tune the angle and position of the electromagnetic suction cup 510. Thus, through the cooperation of the first rotating device 501, the second rotating device 502, the third rotating device 503, the first telescopic arm 508, the fourth rotating device 504, the fifth rotating device 505, the swinging device 507 and the second telescopic arm 509, the casting module 6 can be efficiently and accurately installed on the inner wall of the tunnel 1, thereby improving the construction efficiency and construction quality in the tunnel 1 and effectively reducing the labor cost of construction in the tunnel 1.

[0109] It should be noted that the specific types of the first telescopic arm 508, the second telescopic arm 509 and the third telescopic arm 4037 can be set according to actual needs and are not limited to this. For example, the first telescopic arm 508, the second telescopic arm 509 and the third telescopic arm 4037 are all sliding telescopic arms; the first telescopic arm 508, the second telescopic arm 509 and the third telescopic arm 4037 are all telescopic arms.

[0110] like Figure 6 As shown, in some embodiments, the fourth rotating device 504 includes a fourth base body 5041, a fourth rotating base 5042, and a fourth driving member 5043. The fourth base body 5041 is disposed on the telescopic end of the first telescopic arm 508. The fourth rotating base 5042 is rotatably disposed on the fourth base body 5041. The rotation center axis of the fourth rotating base 5042 is parallel to the rotation center axis of the third rotating device 503. The fourth driving member 5043 is disposed on the fourth base body 5041 and is transmission-connected to the fourth rotating base 5042.

[0111] The swing device 507 includes a base 5071, a swing seat 5072, and a seventh driving member 5073. The base 5071 is mounted on the fourth rotary seat 5042. The swing seat 5072 is rotatably mounted on the base 5071. The rotation axis of the swing seat 5072 is perpendicular to the rotation axis of the fourth rotary seat 5042. The seventh driving member 5073 is mounted on the base 5071 and is in driving connection with the swing seat 5072.

[0112] The fifth rotating device 505 includes a fifth seat body 5051, a fifth rotating seat 5052 and a fifth driving member 5053. The fifth seat body 5051 is set on the swing seat 5072. The fifth rotating seat 5052 is rotatably set on the fifth seat body 5051. The rotation center axis of the fifth rotating seat 5052 is perpendicular to the rotation center axis of the swing seat 5072. The fifth driving member 5053 is set on the fifth seat body 5051, and the fifth driving member 5053 is transmission-connected to the fifth rotating seat 5052.

[0113] It can be understood that, since the fourth rotary seat 5042 is rotatably arranged on the fourth seat body 5041, the fourth rotary seat 5042 is rotated under the drive of the fourth driving member 5043, the fifth rotary seat 5052 is rotated under the drive of the fifth driving member 5053, and the swing seat 5072 is rotatably arranged on the base 5071, the swing seat 5072 is rotated on the base 5071 under the drive of the seventh driving member 5073. Swing, and since the base 5071 is set on the fourth rotating seat 5042, and the fifth rotating seat 5052 is set on the swinging seat 5072, the electromagnetic suction cup 510 can be driven by the cooperation of the fourth driving member 5043, the fifth driving member 5053 and the seventh driving member 5073 to achieve angle adjustment in three directions on the first telescopic arm 508, thereby achieving efficient and accurate installation of the casting module 6 on the inner wall of the tunnel 1, thereby improving the construction efficiency and construction quality in the tunnel 1, and effectively reducing the labor cost of construction in the tunnel 1.

[0114] Among them, the rotation setting method of the fourth rotating seat 5042 on the fourth seat body 5041 and the rotation setting method of the fifth rotating seat 5052 on the fifth seat body 5051 can be set according to actual needs, and there is no restriction on this. For example, the rotation setting method of the fourth rotating seat 5042 on the fourth seat body 5041 and the rotation setting method of the fifth rotating seat 5052 on the fifth seat body 5051 are the same. Taking the rotation setting method of the fourth rotating seat 5042 on the fourth seat body 5041 as an example, a rotating bearing is provided on the fourth seat body 5041, and the fourth rotating seat 5042 is provided on the inner ring of the rotating bearing.

[0115] The transmission method between the fourth driving member 5043 and the fourth rotating seat 5042 and the transmission method between the fifth driving member 5053 and the fifth rotating seat 5052 can be set according to actual needs and are not limited thereto. For example, the transmission method between the fourth driving member 5043 and the fourth rotating seat 5042 and the transmission method between the fifth driving member 5053 and the fifth rotating seat 5052 are the same. Taking the transmission method between the fourth driving member 5043 and the fourth rotating seat 5042 as an example, a worm is provided on the output shaft of the fourth driving member 5043, and a worm wheel is provided on the fourth rotating seat 5042. The worm and worm wheel mesh with each other, thereby achieving rotation of the fourth rotating seat 5042 under the drive of the fourth driving member 5043. The worm and worm transmission method can ensure the rotation accuracy of the fourth rotating seat 5042 and the fifth rotating seat 5052, thereby achieving accurate installation of the casting module 6 on the inner wall of the tunnel 1.

[0116] Among them, the specific types of the fourth driving member 5043 and the fifth driving member 5053 can be set according to actual needs and are not limited to this. For example, the fourth driving member 5043 and the fifth driving member 5053 have the same structure. Taking the fourth driving member 5043 as an example, the fourth driving member 5043 can be a hydraulic motor, and a worm is provided on the output shaft of the hydraulic motor. A worm wheel is provided on the fourth rotating seat 5042, and the worm is engaged with the worm wheel, thereby realizing the rotation of the fourth rotating seat 5042 under the drive of the hydraulic motor.

[0117] The rotation setting method of the swing seat 5072 on the base 5071 can be set according to actual needs and is not limited to this. For example, a rotating shaft is fixedly set on the swing seat 5072, and an axial hole is set on the base 5071, and the rotating shaft is set in the axial hole through a bearing.

[0118] The specific type of the seventh driving member 5073 can be set according to actual needs and is not limited to this. For example, the seventh driving member 5073 can be a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged to the base 5071, and the piston rod end of the hydraulic cylinder is hinged to the swing seat 5072, thereby realizing the swing of the swing seat 5072 on the base 5071 under the drive of the hydraulic cylinder.

[0119] like Figure 1 and Figure 5 As shown, in some embodiments, the assembly work vehicle 5 also includes a sixth rotating device 506, a crank arm lifting assembly 513 and a third working platform 514. The sixth rotating device 506 is arranged on the third flat car 511, and the rotation center axis of the sixth rotating device 506 is perpendicular to the third flat car 511. The crank arm lifting assembly 513 is arranged on the rotating end of the sixth rotating device 506, and the third working platform 514 is arranged on the lifting end of the crank arm lifting assembly 513.

[0120] It can be understood that by rotating the sixth rotating device 506 and lifting and lowering the crank arm lifting assembly 513, the angle and position of the third working platform 514 in the tunnel 1 can be adjusted, so that the operator can reach the predetermined position in the tunnel 1 to assist in the installation of the casting module 6, effectively improving the installation efficiency of the casting module 6 on the inner wall of the tunnel 1 and effectively reducing labor costs.

[0121] It should be noted that the specific type of the crank arm lifting assembly 513 can be set according to actual needs and is not limited to this. For example, the crank arm lifting assembly 513 includes multiple groups of crank arm assemblies, and the crank arm assembly includes a crank arm and a tenth driving member. The multiple crank arms are hinged end to end in sequence, and the tenth driving member is connected to the crank arm transmission. The tenth driving member is arranged on the upper crank arm of the crank arm. Thus, with the cooperation of multiple tenth driving members, the position adjustment of the third working platform 514 is realized.

[0122] Among them, the specific type of the tenth driving member can be set according to actual needs and is not limited to this. For example, the tenth driving member can be a hydraulic cylinder, the piston rod end of the hydraulic cylinder is hinged on the crank arm, and the cylinder end of the hydraulic cylinder is hinged on the upper crank arm of the crank arm, thereby realizing the rotation of the crank arm under the drive of the hydraulic cylinder.

[0123] The specific types of the first work platform 4013, the second work platform 4023, and the third work platform 514 can be set according to actual needs and are not limited to this. For example, the first work platform 4013, the second work platform 4023, and the third work platform 514 have the same structure. Taking the first work platform 4013 as an example, the first work platform 4013 includes a support plate and a fence. The support plate is set on the lifting end of the first scissor-type lifting assembly 4012, and the fence is set around the support plate. In particular, since the cross-section of the tunnel 1 is approximately semicircular, and the first track 2 and the second track 3 are fixed in the horizontal position of the tunnel 1, the distance between the first track 2 and the inner wall of the tunnel 1 at different heights is also different. Therefore, a sliding telescopic structure can be set on the support plates of the first work platform 4013 and the second work platform 4023 to accommodate different distances.

[0124] like Figure 5 As shown, in some embodiments, the sixth rotating device 506 includes a sixth seat body 5061, a sixth rotating seat 5062 and a sixth driving member 5063, the sixth seat body 5061 is set on the third flat car 511, the sixth rotating seat 5062 is rotatably set on the sixth seat body 5061, the rotation center axis of the sixth rotating seat 5062 is perpendicular to the rotation center axis of the third flat car 511, the crank arm lifting assembly 513 is set on the sixth rotating seat 5062, the sixth driving member 5063 is set on the sixth seat body 5061, and the sixth driving member 5063 is connected to the sixth rotating seat 5062 by transmission, and the assembly work vehicle 5 also includes a second movable counterweight device 516, and the second movable counterweight device 516 is set on the sixth rotating seat 5062.

[0125] It can be understood that since the sixth swivel seat 5062 is rotatably set on the sixth seat body 5061, the rotation of the sixth swivel seat 5062 is realized under the drive of the sixth driving member 5063, and since the crank arm lifting assembly 513 is set on the sixth swivel seat 5062, the angle and position of the third working platform 514 in the tunnel 1 can be adjusted under the coordinated drive of the sixth driving member 5063 and the crank arm lifting assembly 513, so that the operating personnel can reach the predetermined position in the tunnel 1 to assist in the installation of the casting module 6, effectively improving the installation efficiency of the casting module 6 on the inner wall of the tunnel 1, and effectively reducing labor costs.

[0126] Among them, through the setting of the second mobile counterweight device 516, the third working platform 514 can maintain balance on the sixth rotating seat 5062 when the angle and position are adjusted, thereby avoiding damage to the rotating structure between the sixth rotating seat 5062 and the sixth seat body 5061 due to uneven force, thereby ensuring safe operation on the third working platform 514.

[0127] Among them, the rotation setting method of the sixth rotating seat 5062 on the sixth seat body 5061 can be set according to actual needs and is not limited to this. For example, a rotating bearing is set on the sixth seat body 5061, and the sixth rotating seat 5062 is set on the inner ring of the rotating bearing.

[0128] The transmission method between the sixth driving member 5063 and the sixth rotating seat 5062 can be configured according to actual needs and is not limited thereto. For example, gears are provided on both the output shaft of the sixth driving member 5063 and the sixth rotating seat 5062. The two gears mesh, thereby driving the sixth driving member 5063 to rotate the sixth rotating seat 5062. The gear transmission method can accommodate the heavy weight on the sixth rotating seat 5062, ensuring stable adjustment of the position and angle of the third working platform 514.

[0129] The specific type of the sixth driving member 5063 can be set according to actual needs and is not limited to this. For example, the sixth driving member 5063 can be a hydraulic motor, and gears are provided on the output shaft of the hydraulic motor and the sixth rotating seat 5062. The two gears are engaged, thereby realizing the rotation of the sixth rotating seat 5062 under the drive of the hydraulic motor.

[0130] The specific types of the first mobile counterweight device 515 and the second mobile counterweight device 516 can be set according to actual needs and are not limited to this. For example, the first mobile counterweight device 515 and the second mobile counterweight device 516 have the same structure. Taking the first mobile counterweight device 515 as an example, the first mobile counterweight device 515 includes a counterweight seat, a counterweight block and a ninth driving member. The counterweight seat is arranged on the first rotating seat 5012, and the counterweight block is arranged on the counterweight seat along the radial sliding direction of the first rotating seat 5012. The ninth driving member is arranged on the counterweight seat, and the ninth driving member is connected to the counterweight block by transmission. Therefore, under the drive of the ninth driving member, the sliding of the counterweight block is realized, thereby realizing the adjustment of the distance between the counterweight block and the central axis of the first rotating seat 5012 to adapt to different positions and angles of the electromagnetic suction cup 510.

[0131] Among them, the specific type of the ninth driving member can be set according to actual needs and is not limited to this. For example, the ninth driving member is a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged on the first rotating seat 5012, and the piston rod end of the hydraulic cylinder is hinged on the counterweight block, thereby realizing the sliding of the counterweight block under the drive of the hydraulic cylinder.

[0132] like Figure 1 As shown, in some embodiments, the assembly work vehicle 5 also includes a fourth flat car 512, a boom 517 and a chain hoist 518. The fourth flat car 512 is arranged on the first track 2, the fourth flat car 512 is connected to the third flat car 511, the casting module 6 is arranged on the fourth flat car 512, the boom 517 is rotatably arranged on the fourth flat car 512, the chain hoist 518 is arranged on the boom 517, and the second hook 519 of the chain hoist 518 is used in conjunction with the second lifting ring 520 on the casting template 604.

[0133] It can be understood that the provision of the fourth flat car 512 facilitates the placement and movement of multiple casting modules 6, avoiding the casting modules 6 being placed on the ground of the tunnel 1, which would affect the operation of the tunnel 1 due to the overall construction. The provision of the boom 517 and the chain hoist 518 facilitates the lifting of the casting modules 6 on the fourth flat car 512, thereby coordinating the actions of multiple rotating devices, the first telescopic arm 508 and other components to install the casting modules 6 on the inner wall of the tunnel 1, thereby improving the construction efficiency in the tunnel 1 and effectively reducing the labor cost of construction in the tunnel 1.

[0134] It should be noted that the rotation setting mode of the boom 517 on the fourth flat car 512 can be set according to actual needs and is not limited to this. For example, a slewing bearing is provided on the fourth flat car 512, and the boom 517 is set on the slewing bearing.

[0135] The drive of the boom 517 can be set according to actual needs and is not limited to this. For example, the boom 517 can be rotated by manual pushing; the boom 517 can be rotated by the drive of a hydraulic motor.

[0136] The location of the second hanging ring 520 on the casting module 6 can be set according to actual needs and is not limited thereto. For example, the second hanging ring 520 can be set on the template 604 of the casting module 6.

[0137] The chain hoist 518 is a light and small lifting equipment. The chain hoist 518 usually includes a motor, a transmission mechanism, a sprocket, a second hook 519, etc. The specific type of the chain hoist 518 can be set according to actual needs and is not limited to this.

[0138] The connection structure between the tractor 9, the first flatcar 405, the second flatcar 406, the third flatcar 511, and the fourth flatcar 512 can be configured according to actual needs and is not limited thereto. For example, the tractor 9, the first flatcar 405, the second flatcar 406, the third flatcar 511, and the fourth flatcar 512 can be connected by a James-type hook. When tunnel 1 construction is not in progress, the tractor 9 can also be separated from the first flatcar 405 for road rescue, equipment transportation, etc.

[0139] The specific types of the first flat cart 405, the second flat cart 406, the third flat cart 511 and the fourth flat cart 512 can be set according to actual needs and are not limited to this. For example, the first flat cart 405, the second flat cart 406, the third flat cart 511 and the fourth flat cart 512 all include a supporting plate and multiple wheels, the multiple wheels are rotatably arranged at the bottom of the supporting plate, and the multiple wheels are rollingly arranged on the first track 2.

[0140] A concrete mixing device and a concrete pumping device may also be provided on the fourth flat car 512 to facilitate pouring of concrete after the pouring module 6 is installed. The specific types of the concrete mixing device and the concrete pumping device may be set according to actual needs and are not limited thereto.

[0141] like Figure 7 As shown, in some embodiments, the tunnel 1 construction work vehicle group also includes multiple support arms 7, multiple eighth driving members and multiple hydraulic support legs 8, the multiple support arms 7 are respectively slidably arranged on both sides of the lifting work vehicle 4 and the assembly work vehicle 5, the multiple eighth driving members are respectively arranged on the lifting work vehicle 4 and the assembly work vehicle 5, the eighth driving members are transmission-connected to the support arms 7, and the hydraulic support legs 8 are arranged on the support arms 7.

[0142] It can be understood that by setting up multiple hydraulic support legs 8, effective support can be formed on both sides of the lifting work vehicle 4 and the assembly work vehicle 5, and by setting up the eighth drive member and the support arm 7, the support position of the hydraulic support legs 8 can be adapted to the different ground environments in the tunnel 1. In this way, the lifting work vehicle 4 and the assembly work vehicle 5 can be avoided from tilting or even falling over during use, thereby ensuring stable construction in the tunnel 1.

[0143] It should be noted that the specific type of the eighth driving member can be set according to actual needs and is not limited to this. For example, taking the eighth driving member on the first flat car 405 as an example, the eighth driving member can be a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged to the first flat car 405, and the piston rod end of the hydraulic cylinder is hinged to the support arm 7, thereby realizing the extension and retraction of the support arm 7 under the drive of the hydraulic cylinder.

[0144] The specific type of the hydraulic support leg 8 can be set according to actual needs and is not limited to this. For example, taking the hydraulic support leg 8 on the first flat car 405 as an example, the hydraulic support leg 8 includes an outer cylinder, an inner column and an eleventh driving member. The outer cylinder is set on the support arm 7, and the inner column is slidingly set at the end of the outer cylinder away from the support arm 7. The eleventh driving member is set on the outer cylinder, and the eleventh driving member is transmission-connected to the inner column. Thus, under the drive of the eleventh driving member, the extension and retraction of the inner column is realized.

[0145] Among them, the specific type of the eleventh driving member can be set according to actual needs and is not limited to this. For example, the eleventh driving member can be a hydraulic cylinder, the cylinder end of the hydraulic cylinder is hinged on the outer cylinder, and the piston rod end of the hydraulic cylinder is hinged to the inner column, thereby realizing the extension and retraction of the inner column under the drive of the hydraulic cylinder.

[0146] The specific type of the casting module 6 can be set according to actual needs, and there is no limitation on this. For example, Figure 8 and Figure 11 As shown, the casting module 6 includes a first arch frame 601, a second arch frame 602, a steel mesh 603 and a template 604. The first arch frame 601 is arranged along the arc direction, the second arch frame 602 is arranged along the arc direction, and the central axis of the second arch frame 602 coincides with the central axis of the first arch frame 601. The steel mesh 603 is arranged between the first arch frame 601 and the second arch frame 602. The template 604 is detachably arranged on the inner side of the first arch frame 601 and the second arch frame 602, wherein multiple casting modules 6 are sequentially arranged on the inner wall of the tunnel 1 along the circumference of the tunnel 1, and a casting cavity 605 is formed between the template 604 and the inner wall of the tunnel 1. It can be understood that by pre-assembling the first arch frame 601, the second arch frame 602, the steel mesh 603 and the template 604 to form a casting module 6, and then installing multiple casting modules 6 on the inner wall of the tunnel 1 along the circumference of the tunnel 1 in sequence, and pouring concrete in the formed casting cavity 605, the workload of pouring concrete in the tunnel 1 is greatly reduced, thereby improving the construction efficiency in the tunnel 1, and effectively reducing the labor cost of construction in the tunnel 1.

[0147] The first arch 601 and the second arch 602 are both arranged along an arc direction, which is a direction that matches the circumference of the tunnel 1 , so that the casting module 6 can be fitted and fixed on the inner wall of the tunnel 1 .

[0148] The inner side of the first arch 601 and the second arch 602 refers to the side of the first arch 601 and the second arch 602 away from the inner wall of the tunnel 1. On the contrary, the outer side of the first arch 601 and the second arch 602 refers to the side of the first arch 601 and the second arch 602 close to the inner wall of the tunnel 1.

[0149] The specific type of the template 604 can be set according to actual needs and is not limited to this. After the concrete in the pouring cavity 605 solidifies, the template 604 is directly removed for recycling. In addition, the template 604 is also used for the adsorption of the electromagnetic suction cup 510 to achieve the fixation of the electromagnetic suction cup 510 to the pouring module 6.

[0150] After multiple casting modules 6 are sequentially arranged on the inner wall of the tunnel 1 along the circumference of the tunnel 1, the casting modules 6 need to be installed again along the axial direction of the tunnel 1. The specific installation method can be set according to actual needs and is not limited to this. For example, in the axial direction of the tunnel 1, adjacent casting modules 6 are installed in sequence without leaving any gaps; in the axial direction of the tunnel 1, supplementary pouring space is left between adjacent casting modules 6, and then a steel mesh 603 and a template 604 are set in the supplementary pouring space, and concrete is poured between the template 604 and the inner wall of the tunnel 1.

[0151] like Figure 9 As shown, in some embodiments, the first arch frame 601 and the second arch frame 602 both include an outer arc plate 6021, an intermediate plate 6022 and an inner arc plate 6023, the outer side of the outer arc plate 6021 is connected to the inner wall of the tunnel 1, the outer side of the intermediate plate 6022 is connected to the inner side of the outer arc plate 6021, the intermediate plate 6022 is perpendicular to the outer arc plate 6021, the intermediate plate 6022 is connected to the steel mesh 603, the outer side of the inner arc plate 6023 is connected to the inner side of the intermediate plate 6022, the inner arc plate 6023 is perpendicular to the intermediate plate 6022, and the template 604 is detachably arranged on the inner side of the inner arc plate 6023. It can be understood that the provision of the outer arc plate 6021 facilitates the installation of the casting module 6 as a whole on the inner wall of the tunnel 1, the provision of the intermediate plate 6022 facilitates the provision of the steel mesh 603 between the first arch frame 601 and the second arch frame 602, and the provision of the inner arc plate 6023 facilitates the disassembly and assembly of the formwork 604. The combined structure of the outer arc plate 6021, the intermediate plate 6022 and the inner arc plate 6023 also makes the cross-section of the first arch frame 601 and the second arch frame 602 form an "I"-shaped structure, which effectively improves the overall strength of the casting module 6 and ensures the stable pouring of concrete.

[0152] Among them, the specific types of the outer arc plate 6021, the middle plate 6022 and the inner arc plate 6023 can be set according to actual needs and are not limited to this. For example, the first arch frame 601 and the second arch frame 602 can be arc-shaped I-beams.

[0153] The detachable structure between the template 604 and the inner arc plate 6023 can be set according to actual needs and is not limited to this. For example, the template 604 and the inner arc plate 6023 are connected by bolt fixation, snap fixation, etc.

[0154] The connection structure between the outer arc plate 6021 and the inner wall of the tunnel 1 can be set according to actual needs and is not limited to this. For example, a plurality of screw holes are provided on the outer arc plate 6021, and the bolts are passed through the screw holes and then threaded on the inner wall of the tunnel 1, thereby achieving the fixation of the outer arc plate 6021 on the inner wall of the tunnel 1. However, the method of opening holes in the outer arc plate 6021 will reduce the structural strength of the outer arc plate 6021, and also increase the processing difficulty of the casting module 6.

[0155] like Figure 9 As shown, in some embodiments, the casting module 6 further includes a plurality of pressure plates 606, one end of each of which abuts the inner side of the outer arc plate 6021, and the other end of each of which is bolted to the inner wall of the tunnel 1. It will be appreciated that the cooperation between the plurality of pressure plates 606 and the bolts constrains the outer arc plate 6021 to the inner wall of the tunnel 1, thereby achieving a fixed installation of the outer arc plate 6021 on the inner wall of the tunnel 1. Furthermore, the abutment secures the outer arc plate 6021 as a whole, preventing damage to the structure of the outer arc plate 6021 and ensuring a high structural strength of the casting module 6 as a whole.

[0156] Among them, the specific type of pressure plate 606 can be set according to actual needs and is not limited to this. For example, the pressure plate 606 includes a first part and a second part, the first part is connected to the second part, the first part abuts against the inner side of the outer arc plate 6021, and a screw hole is provided on the second part, and the bolt is passed through the screw hole and set on the inner wall of the tunnel 1.

[0157] The specific type of the bolt can be set according to actual needs and is not limited to this. For example, the bolt can be an expansion bolt.

[0158] The setting of the pressing plate 606 can be a manual operation, and the operator completes the setting of the pressing plate 606 on the third working platform 514.

[0159] like Figure 10 As shown, in some embodiments, the casting modules 6 further include flanges 607 disposed at the ends of the inner arc plates 6023. The flanges 607 of adjacent casting modules 6 are connected by bolts. It will be appreciated that the engagement of the flanges 607 with the bolts secures adjacent inner arc plates 6023, thereby achieving a fixed connection between adjacent casting modules 6 and ensuring the stable placement of multiple casting modules 6 on the inner wall of the tunnel 1. Furthermore, the bolted fastening not only provides a more secure structure but also simplifies and facilitates operation, effectively improving construction efficiency within the tunnel 1.

[0160] Among them, the specific type of flange 607 can be set according to actual needs and is not limited to this. For example, flange 607 is a plate structure, flange 607 is welded to the end of the inner arc plate 6023, and screw holes are provided on flange 607. The bolts pass through the threaded holes on the adjacent flange 607 and are connected to the nuts.

[0161] The connection of the flange 607 can be a manual operation, and the operator completes the connection of the flange 607 on the third working platform 514.

[0162] like Figure 10 As shown, in some embodiments, the length of the template 604 is less than the length of the first arch 601 and the second arch 602, and a pouring port 609 is formed between the templates 604 of adjacent pouring modules 6. The pouring module 6 also includes a first cover plate 608, which is detachably covered on the pouring port 609. It can be understood that since the length of the template 604 is smaller than the length of the first arch frame 601 and the second arch frame 602, and the first arch frame 601 and the second arch frame 602 of adjacent casting modules 6 are connected, the templates 604 of adjacent casting modules 6 cannot be close to each other, thereby forming a casting port 609. After multiple casting modules 6 are sequentially arranged on the inner wall of the tunnel 1 along the circumference of the tunnel 1, multiple casting ports 609 are formed on the multiple casting modules 6, thereby facilitating the segmented casting of concrete and meeting the process requirements of concrete casting. At the same time, after each section of concrete is filled, the casting port 609 is covered by the first cover plate 608, so that other casting ports 609 can be used to fill the casting cavity 605 with concrete, thereby ensuring that there is a continuous mixed soil structure on the inner wall of the tunnel 1.

[0163] Among them, the covering structure of the first cover plate 608 on the pouring port 609 can be set according to actual needs and is not limited to this. For example, the first cover plate 608 is fixed on the first arch frame 601 and the second arch frame 602 by bolt fixation, snap fixation, etc., and the first cover plate 608 is tightly fitted with the template 604 on the pouring module 6.

[0164] The specific type of the pouring port 609 can be set according to actual needs and is not limited thereto.

[0165] After the first cover plate 608 is closed, the other pouring ports 609 need to be used to completely fill the pouring cavity 605 with concrete. This may easily cause the concrete in the last-closed first cover plate 608 among the multiple first cover plates 608 to fail to be filled.

[0166] The setting of the first cover plate 608 can be a manual operation, and the operator completes the setting of the first cover plate 608 on the third working platform 514 .

[0167] like Figure 10As shown, in some embodiments, a pouring hole is provided on one of the plurality of first cover plates 608, and a second cover plate 610 is detachably attached to the pouring hole. It will be appreciated that by providing a pouring hole on one of the plurality of first cover plates 608, the final pouring of the pouring cavity 605 can be performed through the pouring hole, so that the pouring cavity 605 can be completely filled with concrete, ensuring that the concrete effectively protects the inner wall of the tunnel 1. Furthermore, the provision of the second cover plate 610 prevents concrete from leaking from the pouring hole after pouring is completed, ensuring stable encapsulation of the encapsulated cavity.

[0168] Among them, the first cover plate 608 with the pouring hole can be set according to actual needs and is not limited to this. For example, the first cover plate 608 with the pouring hole can be the first cover plate 608 located at the top of the tunnel 1.

[0169] The covering structure of the second cover plate 610 on the casting hole can be set according to actual needs and is not limited to this. For example, the second cover plate 610 is fixed on the first cover plate 608 by bolt fixing, snap fixing, etc.

[0170] The specific type of the pouring hole can be set according to actual needs and is not limited thereto, but the pouring hole should be small in size while being able to be filled with concrete.

[0171] The second cover plate 610 may be set up manually, and the operator completes the setting of the second cover plate 610 on the third working platform 514 .

[0172] like Figure 8 and Figure 10 As shown, in some embodiments, the steel mesh 603 includes a plurality of first steel bars 6031, a plurality of second steel bars 6032, and a plurality of third steel bars 6033. One end of the first steel bar 6031 is connected to the first arch 601, the other end of the first steel bar 6031 is connected to the second arch 602, the second steel bar 6032 is connected to the first steel bar 6031, and the second steel bars 6032 of adjacent casting modules 6 are connected to each other. The third steel bar 6033 is connected to the first steel bar 6031 and the second steel bar 6032, respectively. The first steel bar 6031, the second steel bar 6032, and the third steel bar 6033 are perpendicular to each other. It can be understood that because the first steel bar 6031, the second steel bar 6032, and the third steel bar 6033 are perpendicular to each other, after the concrete is poured, the steel mesh 603 can exert tension in three perpendicular directions, thereby effectively improving the structural strength of the concrete after pouring and ensuring that the concrete effectively protects the inner wall of the tunnel 1.

[0173] Among them, the specific directions of the first steel bar 6031, the second steel bar 6032 and the third steel bar 6033 can be set according to actual needs and are not limited to this. For example, the length direction of the first steel bar 6031 is located in the axial direction of the tunnel 1, the length direction of the second steel bar 6032 is located in the circumferential direction of the tunnel 1, and the length direction of the third steel bar 6033 is located in the radial direction of the tunnel 1.

[0174] The arrangement of the first steel bar 6031 between the first arch frame 601 and the second arch frame 602 can be arranged according to actual needs and is not limited to this. For example, the two ends of the first steel bar 6031 are respectively connected to the middle plate 6022 of the first arch frame 601 and the middle plate 6022 of the second arch frame 602 by welding, overlapping, etc.

[0175] The connection method between the first steel bar 6031 and the second steel bar 6032 and the third steel bar 6033 can be set according to actual needs and is not limited to this. For example, the first steel bar 6031 is connected to the second steel bar 6032 and the third steel bar 6033 respectively by welding, overlapping, etc.

[0176] The connection method between the second steel bars 6032 of adjacent casting modules 6 can be set according to actual needs and is not limited to this. For example, the second steel bars 6032 of adjacent casting modules 6 are connected by welding, overlapping, etc.

[0177] The connection between the second steel bars 6032 of adjacent casting modules 6 can be done manually, and the operator completes the connection between the second steel bars 6032 of adjacent casting modules 6 on the third working platform 514.

[0178] like Figure 8 and Figure 10 As shown, in some embodiments, a bent portion 6034 is provided at the end of the third steel bar 6033, and the bent portion 6034 is hung on the second steel bar 6032. It can be understood that the third steel bar 6033 and the second steel bar 6032 are connected by hanging, which ensures the structural strength after concrete pouring while being simple and convenient to operate, thereby effectively improving the assembly efficiency of the pouring module 6.

[0179] like Figure 8 As shown, in some embodiments, the pouring module 6 further includes a plurality of reinforcing plates 611, which are disposed on the inner side of the formwork 604. It is understood that the provision of the plurality of reinforcing plates 611 effectively improves the structural strength of the formwork 604, thereby ensuring stable pouring of concrete and effectively improving the safety of construction in the tunnel 1.

[0180] Among them, the specific type of the reinforcing plate 611 can be set according to actual needs and is not limited to this. For example, the reinforcing plate 611 can be a channel steel, which is welded to the inner side of the template 604, and the groove of the channel steel is located on the side of the reinforcing plate 611 away from the template 604.

[0181] like Figure 11 As shown, in some embodiments, the multiple casting modules 6 include two first modules 612, two second modules 613, and a third module 614. The first module 612 is disposed on the inner wall of the tunnel 1 at one end close to the ground of the tunnel 1. The second module 613 is disposed on the inner wall of the tunnel 1, with one end of the second module 613 connected to the end of the first module 612 away from the ground of the tunnel 1. The third module 614 is disposed on the inner wall of the tunnel 1, with the ends of the third module 614 respectively connected to the ends of the two second modules 613 away from the first module 612. It can be understood that dividing the casting modules 6 circumferentially along the inner wall of the tunnel 1 into five pieces, with two first modules 612 and two second modules 613, not only facilitates concrete pouring within the tunnel 1 and improves construction efficiency within the tunnel 1, but also facilitates processing and assembly, effectively reducing labor costs during construction within the tunnel 1.

[0182] Among them, after the operators roughened and planted steel bars on the inner wall of the tunnel 1 on the first working platform 4013 and the second working platform 4023, they first installed the two first modules 612 by adsorption and angle and position adjustment of the electromagnetic suction cup 510, and then installed the two second modules 613 by adsorption and angle and position adjustment of the electromagnetic suction cup 510, and finally installed the third module 614 by adsorption and angle and position adjustment of the electromagnetic suction cup 510.

[0183] After the concrete solidifies, the workers complete the removal of the first cover plate 608 , the second cover plate 610 , the formwork 604 and other components on the first working platform 4013 and the second working platform 4023 or the third working platform 514 .

[0184] It should be noted that, in the description of this disclosure, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.
