Description

Technical Field

[0001] This application relates to the technical field of tunnel construction equipment, and particularly to a tunnel steel tile transportation and adjustment device. Background Art

[0002] Currently, in the concrete pipe reinforcement project in the tunnel, steel tiles are required. The assembled steel tiles are transported to the designated position in the tunnel and then butt-jointed and welded.

[0003] However, there are problems such as large inner diameter, long transportation distance, difficult assembly, and small gap between the steel tile and the tunnel for the transported steel tiles. For the concrete pipe reinforcement in the tunnel, single or several groups of steel tiles with a length of several kilometers need to be transported, and the gap between the assembled steel tile and the tunnel pipe is only dozens of millimeters. The large-diameter steel tiles transported over a long distance are prone to deflection during transportation. When the steel tiles are butt-jointed, they need to be rotated and assembled, and it takes time and labor to build an assembly and rotation platform in the tunnel.

Detailed implementation mode

[0059] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0060] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which this application belongs.

[0061] As Figures 1-4 shown, an apparatus for transporting and adjusting tunnel steel tiles proposed in Embodiment 1 of the present invention includes:

[0062] Support beam 1;

[0063] Two traveling mechanisms 2, respectively arranged at both ends of the support beam 1, for driving the support beam 1 to move;

[0064] Two workpiece fixing mechanisms 3, both connected to the support beam 1 and spaced between the two traveling mechanisms 2, and the workpiece fixing mechanism 3 is configured to be able to extend or contract along the radial direction of the support beam 1 to support and fix steel tile workpieces 8 with different pipe diameters;

[0065] Two guiding mechanisms 5, both connected to the support beam 1, respectively arranged between the adjacent traveling mechanism 2 and the workpiece fixing mechanism 3, and the guiding mechanism 5 is configured to be able to extend or contract along the radial direction of the support beam 1 to achieve contact with the inner wall of the tunnel 7 with different structures at different positions of the tunnel 7, so as to adjust the moving direction of the tubular steel tile workpiece 8 during walking and prevent the traveling mechanism 2 from moving off and causing collisions between the steel tile workpiece 8 and the tunnel 7.

[0066] Specifically, the support beam 1 is the main load-bearing structure, which needs to have high strength. The cross-section can be I-shaped, circular ring-shaped, rectangular ring-shaped, etc., and preferably circular ring-shaped, that is, the support beam 1 can be made of a metal tube body with a certain strength. The length of the support beam 1 can be designed according to the use needs, and the embodiments of the present invention do not make limitations.

[0067] The two traveling mechanisms 2 can adopt the way of roller movement to drive the support beam 1, the workpiece fixing mechanism 3, the guiding mechanism 5 and the steel tile workpiece 8 to move together. The way of driving the rollers can be electric motor, hydraulic pressure, etc., and the embodiments of the present invention do not make limitations. In addition, the traveling mechanism 2 can preferably be adjusted in the height direction, that is, preferably, a telescopic device can be provided so that it can adjust the height of the support beam 1. It should be noted that the structures of the two traveling mechanisms 2 are the same. The two traveling mechanisms 2 need to be respectively arranged at both ends of the support beam 1, which can be the ends of both ends or the positions at both ends close to the ends. The connection with the support beam 1 can be welding, bolt connection or connection with a clamp.

[0068] The workpiece fixing mechanism 3 is also provided on the support beam 1 and is located between the two traveling mechanisms 2. Moreover, the structures of the two workpiece fixing mechanisms 3 are the same. In this way, when fixing the steel tile workpiece 8, the two workpiece fixing mechanisms 3 can be free from the interference of the two traveling mechanisms 2. In addition, since the steel tile workpiece 8 is an annular body formed by connecting multiple tiles, the workpiece fixing mechanism 3 is configured to be able to extend or contract radially along the support beam 1, so as to support the steel tile workpieces 8 with different diameters. That is, it can support the steel tile workpiece 8 when extending, and it is convenient to unload the steel tile workpiece 8 from the workpiece fixing mechanism 3 when contracting.

[0069] The two guiding mechanisms 5 are used to assist the traveling mechanism 2 in transporting the steel tile workpiece 8. Since the cylinder tile workpiece is transported in the tunnel 7, the guiding mechanisms 5 are also configured to be able to extend or contract radially along the support beam 1. In this way, the guiding mechanisms 5 can adjust the telescopic distance of their own structures according to the structure and diameter of the tunnel 7, and at the same time ensure the clearance distance between the supported steel tile workpiece 8 and the tunnel 7 to ensure the smooth progress of the transportation.

[0070] The tunnel steel tile transportation and adjustment device provided by the embodiment of the present invention includes a support beam 1, and a traveling mechanism 2, a workpiece fixing mechanism 3, and a guiding mechanism 5 provided on the support beam 1. The workpiece fixing mechanism 3 is arranged between the two traveling mechanisms 2, and the guiding mechanism 5 is arranged on both sides of the workpiece fixing mechanism 3. By controlling the telescoping of the traveling mechanism 2 and the workpiece fixing mechanism 3 and the telescoping of the guiding mechanism 5, the fixing of the steel tile workpieces 8 with different pipe diameters and the moving and assembling processes in different tunnels 7 are realized. The transportation device has a high degree of automation, high transportation and adjustment efficiency, and high butt joint accuracy of the steel tile workpieces 8.

[0071] As Figures 1-5 、 Figure 9 shown, in a specific implementation, the workpiece fixing mechanism 3 includes: a first support sleeve 31 sleeved on the outer surface of the support beam 1 and connected to the support beam 1; a first rotating device 33 including a first fixing part 331 and a first rotating part 332. The first fixing part 331 is fixedly connected to the first support sleeve 31, and the first rotating part 332 is sleeved outside the first fixing part 331 and rotatably connected to the first fixing part 331; a first rotating seat 32 sleeved on the outer wall of the first rotating part 332 and fixedly connected to the first rotating part 332; a plurality of first support components 34 circumferentially spaced and connected to the first rotating seat 32. The first support components 34 extend along the radial direction of the support beam 1, and the first support components 34 can extend or contract along the radial direction of the support beam 1.

[0072] Specifically, the first support sleeve 31 is sleeved outside the support beam 1 and can be fixedly connected or slidably connected to the support beam 1. The shape and size of the first support sleeve 31 are adapted to those of the support beam 1, and it is arranged as a hollow cylindrical structure. The structure of the first rotating device 33 is similar to that of a bearing. Ball bearings can be arranged between the first fixed part 331 and the first rotating part 332, or a self-lubricating metal sleeve can be directly arranged between the two, as long as it is ensured that the first fixed part 331 and the first rotating part 332 can rotate relative to each other. The first rotating seat 32 can be integrally plate-shaped, and a through hole or a flange capable of connecting to the first rotating part 332 is arranged in the middle, and it can be connected to the first rotating part 332 by welding or bolt connection. The number of the first support assemblies 34 can be set according to the usage requirements. For example, it can be 3 or more than 3. The angles between the first support assemblies 34 can be equal or unequal. The first support assemblies 34 are controlled to extend or contract to fix steel tile workpieces 8 with different pipe diameters. At the same time, the first support assemblies 34 can also rotate relative to the axis of the support beam 1 along with the first rotating seat 32, so as to adjust the first support assemblies 34 so that the first support assemblies 34 can fix workpieces with different shapes and positions.

[0073] Further, the first support assembly 34 includes a main support assembly 344 and two auxiliary support assemblies 345. The main support assembly 344 is vertically arranged, and the upper end of the main support assembly 344 facing upwards can reciprocally extend and contract. The two auxiliary support assemblies 345 are located on both sides of the main support assembly 344, and the three are arranged at equal intervals circumferentially, that is, the three are evenly distributed on the first rotating seat 32 in a circular pattern with the center of the first rotating seat 32 as the center of the circle. The end of the auxiliary support assembly 345 away from the first rotating seat 32 can reciprocally extend and contract. Among them, first strengthening rods 36 are respectively arranged between both sides of the main support assembly 344 and the first rotating seat 32 to increase the connection strength of the first support assembly 34.

[0074] Specifically, the first support assembly 34 can be a telescopic drive structure of a hydraulic cylinder or a pneumatic cylinder. For example, the first support assembly 34 can include a first cylinder block 341 and a first telescopic rod 342 disposed within the first cylinder block 341. The first cylinder block 341 is connected to the first rotating seat 32, and the first telescopic rod 342 can be telescoped relative to the first cylinder block 341 so that the top of the first telescopic rod 342 is in hinge contact with the inner wall of the steel tile workpiece 8 to apply an outward force to the steel tile workpiece 8, thereby achieving the fixation of the steel tile workpiece 8 with different pipe diameters. Preferably, a clamping groove 343 is provided at one end of the first support assembly 34 away from the first rotating seat 32 for clamping on the reinforcing rib of the steel tile workpiece 8, and through holes are provided on the opposite two groove walls of the clamping groove 343 for being fixedly connected to the steel tile through the insertion of a pin while clamping the reinforcing rib. That is, the top of the first telescopic rod 342 is fixedly provided with a clamping groove 343 and through holes are provided on the groove walls to increase the activity area between the first telescopic rod 342 and the steel tile workpiece 8, improve the flexibility between the two, and at the same time avoid the inner wall structure of the tubular workpiece being damaged by point-to-surface contact.

[0075] As Figures 1-5 , Figure 9 shown, in a specific implementation, the workpiece fixing mechanism 3 further includes: a first driving device 35 connected to the first rotating part 332, and by controlling the first driving device 35, the first rotating part 332, the first rotating seat 32, and the first support assembly 34 are driven to rotate relative to the support beam 1. The first driving device 35 includes a driving motor and a speed reducer. The driving motor is a variable-frequency motor, and the speed reducer includes a worm and worm gear type speed reducer. In this embodiment, the variable-frequency motor drives the worm and worm gear type speed reducer to drive the first rotating part 332 to rotate relative to the first fixed part 331, that is, to drive the first rotating seat 32 and the first support assembly 34 fixed to the first rotating part 332 to rotate around the axis of the support beam 1, realizing the rotation of the steel tile workpiece 8 around the axis of the support beam 1, which is convenient for the docking of the steel tile workpiece 8 in the curved section of the tunnel 7.

[0076] In a specific implementation, the first support sleeve 31 is slidably connected to the support beam 1, and the two workpiece fixing mechanisms 3 can slide along the support beam 1 to approach or move away from each other, and further, the two workpiece fixing mechanisms 3 arranged at intervals can support the steel tile workpiece 8 with different lengths.

[0077] As Figures 1-4 , Figure 7 , Figure 10As shown, in a specific implementation, the guiding mechanism 5 includes: a second support sleeve 51 sleeved on the outer surface of the support beam 1 and connected to the support beam 1; a plurality of second support components 52 spaced apart on the outer surface of the second support sleeve 51, and one end of the second support component 52 away from the second support sleeve 51 can reciprocally expand and contract.

[0078] Specifically, the plurality of second support components 52 can be 3 or more, which can be set according to the actual situation. Preferably, the plurality of second support components 52 are evenly spaced around the lower half of the horizontal outer surface of the second support sleeve 51. For example, 4 second support components 52 are provided, and the included angle between two adjacent second support components 52 is 60 degrees, and two of them are in a horizontal position and extend in opposite directions. Thus, the guiding structure can effectively support and guide left and right. In addition, a first baffle 512, a rib plate 513, and a connecting rod 514 can be added. The first baffle 512, that is, a reinforcing plate, is connected to the two second support components 52 in the horizontal position to improve stability. The connecting rod 514 connects two adjacent second support components 52 and is hinged to the second support component 52, which also improves stability and can also improve the structural strength. The rib plate 513 is connected between the second support sleeve 51 and the second support component 51, which also improves the overall structural strength.

[0079] Furthermore, the second support component 52 can be a telescopic structure of a hydraulic cylinder or a pneumatic cylinder. As Figure 8 shown, the second support component 52 includes: a support tube body 521, the first end of the support tube body 521 is connected to the second support sleeve 51; a first telescopic component 522 disposed in the support tube body 521, and the first end is connected to the second support sleeve 51; a support rod 523, one end of the support rod 523 is connected to the second end of the first telescopic component 522, and the other end extends out of the second end of the support tube body 521; a guide wheel 524 connected to the other end of the support rod 523.

[0080] Specifically, the first telescopic component 522 can be the above-mentioned hydraulic cylinder or pneumatic cylinder. The guide wheel 524 can be a universal wheel or a one-way wheel whose rotation direction is along the length direction of the support beam 1. By controlling the first telescopic component 522, the distance between the guide wheel 524 and the support tube body 521 can be adjusted, that is, the radial telescopic dimension is controlled, so that the guide wheel 524 contacts tunnels 7 with different diameters, and the movement direction of the tunnel 7 steel tile workpiece 8 transportation device and the docking deviation between the steel tile workpieces 8 are corrected, thereby ensuring the smooth transportation and docking accuracy of the steel tile workpiece 8.

[0081] In other optional implementations, the guide mechanism 5 may also be arranged on the outside of the traveling mechanism 2 and on the side of the traveling mechanism 2 away from the workpiece fixing mechanism 3. It should be noted that the two guide mechanisms 5 should be arranged symmetrically.

[0082] like Figures 1-4 , Figure 6 and Figure 11 As shown, in a specific implementation, the walking mechanism 2 includes: a walking beam 21; a power wheel group 22, which is arranged at the bottom of both ends of the walking beam 21; a second driving device 23, which is arranged on the walking beam 21 and connected to the power wheel group 22, and is used to drive the power wheel group 22 to rotate and move the walking beam 21; a third support assembly 24, including two vertical and mutually parallel second telescopic assemblies 241 and a first connecting plate 242 fixedly connected to the tops of the two second telescopic assemblies 241, the bottoms of the two second telescopic assemblies 241 are respectively connected to the two ends of the upper surface of the walking beam 21, and the first connecting plate 242 is fixedly connected to the support beam 1, and the height of the support beam 1 can be adjusted by the second telescopic assembly 241 reciprocating in the vertical direction.

[0083] Specifically, the two second telescopic components 241 are parallel to each other and are longitudinally fixed on the walking beam 21, that is, the second telescopic component 241 is perpendicular to the walking beam 21. One end of the second telescopic component 241 is fixedly connected to the walking beam 21, and the other end extends upward. The first connecting plate 242 can be welded to the support beam 1, and the first connecting plate 242 can be set to a pipe hoop shape and fastened by bolts. Since the two workpiece fixing mechanisms 3 are fixed on the support beam 1 and are used to fix the steel tile workpiece 8, the height of the workpiece from the ground is controlled by controlling the extension or contraction of the second telescopic component 241 to prevent the steel tile workpiece 8 from colliding with the tunnel 7. In addition, the specific installation position of the third support assembly 24 can also be installed according to actual needs, for example, it can be set in the middle position of the walking beam 21.

[0084] Furthermore, the power wheel set 22 includes a driving wheel set 221. The two driving wheel sets 221 are arranged at the bottom of the walking beam 21, so that the walking mechanism 2 forms a two-wheel drive moving device, thereby smoothly driving the walking beam 21 to move. The two driving wheel sets 221 are fixed to the bottom of the walking beam 21 in an eight-shaped structure installation method. The eight-shaped structure can ensure that the movement direction of the power wheel set 22 is always in contact with the inner wall of the tunnel 7 (such as the cross section of the tunnel 7 is circular, the eight-shaped structure ensures that the power wheel set 22 is tangent to the inner wall of the tunnel 7), which can avoid the slippage caused by the small contact surface between the power wheel set 22 and the tunnel 7.

[0085] The second driving device 23 includes a driving motor, a speed reducer, and a transmission device. The transmission device includes a chain and a sprocket. The driving motor is drivingly connected to the sprocket through the speed reducer, and the sprocket and the driving wheel set 221 are drivingly connected through the chain. Specifically, for the driving wheel set 221 of the traveling mechanism 2, the driving motor drives the sprocket through the speed reducer, and the sprocket drives the driving wheel set 221 to move in the tunnel 7 through the chain. In this embodiment, the driving motor can be a variable-frequency motor or the like. The driving wheel set 22 of the traveling mechanism 2 in this embodiment is driven by a chain, which can reduce the vibration impact on the speed reducer caused by the unevenness of the tunnel 7 and extend the service life of the speed reducer. In other alternative implementation manners, the transmission device can be arranged in other driving connection manners and be drivingly connected to the driving wheel set 221. For example, a gear transmission device.

[0086] As Figure 1 and Figure 2 shown, in a specific implementation, the tunnel steel tile transportation and adjustment device in the embodiment of the present invention further includes: a power source 4, which is arranged on the traveling mechanism 2 and is used to provide energy for the traveling mechanism 2, the workpiece fixing mechanism 3, and the guiding mechanism 5.

[0087] Specifically, the power source 4 can be a hydraulic station or a gas source station, and is used to provide energy for the first support assembly 34 of the workpiece fixing mechanism 3 above, provide energy for the second support assembly 52 of the guiding mechanism 5, and provide energy for the third support assembly 24 of the traveling mechanism 2. For example, when the first support assembly 34 is hydraulically driven, the power source 4 is set as a hydraulic station, and when the first support assembly 34 is pneumatically driven, the power source 4 is set as a gas source station. Similarly, this also applies to the second support assembly 52 and the third support assembly 24.

[0088] As Figure 1 and Figure 2 shown, in a specific implementation, the tunnel steel tile transportation and adjustment device in the embodiment of the present invention further includes: a control module 6, which is arranged on the traveling mechanism 2.

[0089] Specifically, the control module 6 is used to control the actions of the traveling mechanism 2, the workpiece fixing mechanism 3, and the guiding mechanism 5 above, and control the power source 4 above to provide energy for the traveling mechanism 2, the workpiece fixing mechanism 3, and the guiding mechanism 5. The control module 6 can include a remote control component for the staff to achieve remote control. The control program used in the control module 6 is a program written by technicians according to the actual application scenario and is easily obtained by technicians. The embodiment of the present invention will not elaborate.

[0090] Among them, the control module 6 is used to control the realization of various functions of the transportation device of the steel tile workpiece 8 in the tunnel 7. For example, the second driving device 23 of the driving walking mechanism 2 is controlled to drive the support beam 1, the guide mechanism 5, and the workpiece fixing mechanism 3 to walk; the second telescopic component 241 of the walking mechanism 2 is controlled to be telescopic, thereby controlling the distance between the support beam 1 and the ground of the tunnel 7; the first supporting component 34 of the workpiece fixing mechanism 3 is controlled to be telescopic to achieve the fixation of steel tile workpieces 8 of different diameters; the first driving device 35 of the driving workpiece fixing mechanism 3 is controlled to make the tubular steel tile workpiece 8 fixed to the workpiece fixing mechanism 3 rotate relative to the support beam 1; the end of the second supporting component 52 of the guiding mechanism 5 is controlled to be telescopic to adjust the moving direction of the transportation device in the tunnel 7 and the docking accuracy of the steel tile workpiece 8.

[0091] In addition, when the walking mechanism 2 is being transported in the tunnel 7 and the walking mechanism 2 is deflected, the control module 6 controls the second telescopic component 241 of the walking mechanism 2 to shrink to the shortest, and supports the inner wall of the tunnel 7 through the second telescopic component 241 of the guide mechanism 5 so that the walking mechanism 2 is separated from the bottom surface of the tunnel 7, and the gravity is used to make the walking mechanism 2 perpendicular to the bottom surface of the tunnel 7. Finally, the second telescopic component 241 of the walking mechanism 2 is controlled to extend to contact with the inner wall of the tunnel 7, ensuring that the movement directions of the two walking mechanisms 2 in the tunnel 7 are consistent, which can prevent the steel tile workpiece 8 from colliding with the tunnel 7 and improve the transportation efficiency of the transportation device.

[0092] In a specific implementation, the tunnel steel tile operation and dispatching device in the embodiment of the present invention further includes: a power supply mechanism (not shown in the figure) is arranged on the walking mechanism 2, and is electrically connected to the two first drive devices 35 and the two second drive devices 23 respectively for power supply. The power supply mechanism is a generator set or a battery set, etc.

[0093] Based on the specific structure of the tunnel steel tile transportation device of the present invention, the embodiment of the present invention also provides a method for using Figures 1-11 The method of transporting the steel tile workpiece 8 by the tunnel steel tile transport device shown:

[0094] (1) Control the tunnel 7 steel tile workpiece 8 transport device to move to the position for transporting the steel tile workpiece 8.

[0095] (2) According to the transportation direction of the steel tile workpiece 8 (defined as from left to right, where left and right are the length directions of the support beams 1. At this time, the steel tile workpiece 8 is located at the right end of the tunnel steel tile transportation and adjustment device. At this time, the two traveling mechanisms 2, the two workpiece fixing mechanisms 3, and the two guiding mechanisms 5 of the tunnel steel tile transportation and adjustment device are evenly divided into left and right sides for description), the control module 6 controls the second telescopic component 241 of the guiding mechanism 5 to extend to the limit, controls the main support component 344 of the first support component 34 to the highest limit position, then selects the hoisting method to slowly place the steel tile on the main support component 344 and fixes it with a pin shaft, and fixes it with the auxiliary support component 345 on both sides.

[0096] (3) The control module 6 controls the main support component 344 and the auxiliary support component 345 to contract to the innermost position, that is, the shortest state.

[0097] (4) Control the traveling mechanism 2 to move to the right.

[0098] (5) When the traveling mechanism 2 reaches the position where the steel tile needs to be supported, first, the control module 6 controls the auxiliary support component 345 to extend to the maximum position, and then the control module 6 controls the main support component 344 to extend, so that the steel tile reaches the maximum opening position.

[0099] (6) When the angle of the transported steel tile is not appropriate, it needs to be rotated to the appropriate angle and then the steel tile is opened.

[0100] (6) When the right traveling mechanism 2 moves out from inside the steel tile workpiece 8, first lay a track on the steel tile, control the right guiding wheel 524 to retract and move the traveling mechanism 2 back, so that the guiding wheel 524 is located above the laid track, control the guiding wheel 524 to contact the laid track, and make the power wheel set 22 on the right leave the bottom surface of the tunnel 7 and be higher than the laid track.

[0101] (7) Control the traveling mechanism 2 to move to the left. When the right guiding wheel 524 is about to leave the laid track, control the power wheel set 22 on the right to contact the laid track, and control the guiding wheel 524 to leave the laid track. When controlling the guiding wheel 524 to leave the laid track and controlling the guiding wheel 524 to contact the bottom surface of the tunnel 7, control the right traveling wheel to leave the laid track and continue to move to the left.

[0102] (8) When controlling the power wheel set 22 on the right to completely disengage from the laid track, control the power wheel set 22 on the right to contact the bottom surface of the tunnel 7, and control the guiding wheel 524 to leave the bottom surface of the tunnel 7, control the steel tile transportation and adjustment device to move to the position for transporting the next steel tile, and prepare for the next process.

[0103] (9) Control the traveling mechanism 2 to move in the predetermined direction inside the tunnel 7.

[0104] Among them, during the transportation of the steel tile workpiece 8, when the traveling mechanism 2 deflects, the control module 6 controls the contraction of the second telescopic component 241 of the traveling mechanism 2, so that the driving wheel set 22 of the deflected traveling mechanism 2 is separated from the bottom surface of the tunnel 7. By using the center of gravity effect, the traveling mechanism 2 is perpendicular to the bottom surface of the tunnel 7, and the deviation of the traveling mechanism 2 is corrected; then the control module 6 controls the extension of the second telescopic component 241 of the traveling mechanism 2 to contact the bottom surface of the tunnel 7 and continue to move in the predetermined direction.

[0105] (10) When the control module 6 controls the traveling mechanism 2 to move along the tunnel 7 to the position where the steel tile workpiece 8 needs to be docked, the control module 6 controls the first telescopic component 522 of the left guiding mechanism 5 to contract to the shortest. The control module 6 slowly controls the traveling mechanism 2 to continue moving, so that the right guiding mechanism 5 completely moves into the steel tile workpiece 8 to be docked. The control module 6 controls the first telescopic component 522 of the guiding mechanism 5 to extend, so that the guiding wheels 524 of the right guiding mechanism 5 are completely attached to the laying track of the steel tile workpiece 8 to be docked; at the same time, the control module 6 controls the second telescopic component 241 of the right traveling mechanism 2 to contract to the shortest, so that the driving wheel set 22 of the right traveling mechanism 2 is separated from the bottom surface of the tunnel 7.

[0106] (11) The control module 6 controls the left traveling mechanism 2 to move rightward along the tunnel 7. When the steel tile workpiece 8 on the transportation device approaches the steel tile workpiece 8 to be docked, the control module 6 controls the second telescopic component 241 of the left traveling mechanism 2 to expand and contract, so that the axis of the support beam 1 is located at the center line of the steel tile workpiece 8 that has been to be docked. The control module 6 controls the left traveling mechanism 2 to move rightward along the tunnel 7 to automatically dock the two steel tile workpieces 8, thereby reducing the process of aligning the two steel tile workpieces 8.

[0107] (12) After the two steel tile workpieces 8 are firmly welded, the control module 6 controls the first support components 34 of the left workpiece fixing mechanism 3 and the first support components 34 of the right workpiece fixing mechanism 3 to contract, so that the workpiece fixing mechanisms 3 on both sides are separated from the steel tile workpiece 8; at the same time, the control module 6 controls the left traveling mechanism 2 to move leftward along the tunnel 7. When the right traveling mechanism 2 is separated from the laying track of the steel tile workpiece 8, the control module 6 controls the second telescopic component 241 of the right traveling mechanism 2 to extend, so that the driving wheel set 22 of the right traveling mechanism 2 contacts the bottom surface of the tunnel 7. The control module 6 controls the first telescopic component 522 of the right guiding mechanism 5 to contract, so that the guiding wheels 524 of the right guiding mechanism 5 are completely separated from the steel tile workpiece 8. If the welding of the steel tile workpiece 8 is carried out in the curved section tunnel 7, it is necessary to control the left workpiece fixing mechanism 3 and the right workpiece fixing mechanism 3 to rotate, so that the steel tile workpiece 8 rotates to a suitable position and then is welded after being docked with the steel tile workpiece 8 to be docked.

[0108] (13)Continue to control the left and right traveling mechanisms 2 to move left along the tunnel 7, so that the guiding mechanism 5 on the right is completely disengaged from the steel tile workpiece 8; when the guiding mechanism 5 on the right is completely disengaged from the steel tile workpiece 8, the control module 6 controls the guiding mechanism 5 on the right to extend, so that the guide wheels 524 of the guiding mechanism 5 on the right are completely attached to the inner wall of the tunnel 7, and the control module 6 controls the traveling mechanism 2 to move to the left of the storage position of the steel tile workpiece 8 to be transported, to prepare for the next transportation.

[0109] (14)To improve the automation of steel tile transportation, an inclination sensor is installed on the cross beam of the traveling mechanism 2, which can detect that the traveling mechanism 2 moves along a spiral line in the tunnel 7 to improve the safety of steel tile transportation.
