Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to a hydraulic assembly system for bridge expansion joint components. Background Technology

[0002] Bridge expansion joints are devices installed in the gaps between two adjacent bridge beams to accommodate bridge deck deformation. These beams can be main girder segments or abutments connected to the main girder. Bridge expansion joints are required to allow free expansion and contraction in both the length and width directions of the bridge, be robust and reliable, ensure a smooth ride for vehicles without bumps or noise, and prevent rainwater, debris, and mud from seeping in and causing blockages. Therefore, bridge expansion joints play a crucial role in the expansion, contraction, waterproofing, and drainage performance of the bridge beam ends, and their quality and performance directly affect the durability of the entire bridge.

[0003] The manufacturing process of bridge expansion joint components involves multiple steps, and the parts of the bridge expansion joint components need to be hoisted to the corresponding work positions in different steps. Therefore, the manufacturing efficiency is low, and there are safety hazards during the hoisting process, which may even lead to worker injuries. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a hydraulic assembly system for bridge expansion joint components, which can improve the manufacturing efficiency of bridge expansion joint components, reduce the frequency of component hoisting, and effectively prevent safety accidents.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A hydraulic assembly system for bridge expansion joint components includes an assembly platform and a pressure-bearing platform and a pressurizing platform disposed on the assembly platform. The pressure-bearing platform is fixedly disposed on the assembly platform and is used to fix two comb-tooth steel plates. A dustproof plate is welded to the two comb-tooth steel plates on the pressure-bearing platform, and a buffer and a water guide channel are placed on the dustproof plate. A buffer pad is disposed between the buffer and the dustproof plate, and the buffer and the water guide channel are welded to each other. The side of the water guide channel away from the buffer is welded to the corresponding comb-tooth steel plate.

[0007] Pressure plates are respectively provided on both sides of the assembly platform. The two ends of the pressure plates are connected to the assembly platform through hydraulic cylinders. A flipping shaft is fixedly provided on one side of the pressure plate. The two ends of the flipping shaft are rotatably connected to the two pressure plates respectively. The flipping shaft is driven by a flipping motor so that the pressure plates can be flipped onto the pressure bearing platform.

[0008] Two fixing plates are provided on one side of the pressure platform. Each fixing plate is provided with a clamp for holding the fin plate and the connecting plate on the side facing away from the pressure platform. The fin plate and the connecting plate are welded to form a fin. After the pressure platform is flipped, it is pressed against the pressure platform by the hydraulic cylinder. The fin of one fixing plate can press against the buffer, the water guide groove and the corresponding comb plate. The fin of the other fixing plate can press against the dustproof plate and the corresponding comb plate. By welding one fin to the corresponding comb plate and welding the other fin to the dustproof plate and the corresponding comb plate, an expansion joint component is formed.

[0009] Each of the pressure plates is provided with an anti-tilting mechanism, which is used to limit the tilting of the pressure plate away from the tilting axis when the hydraulic cylinder pressurizes.

[0010] Furthermore, the clamp includes a first clamp and a second clamp. A plurality of first clamps are arranged alternately along the axial direction of the flipping shaft, and each first clamp includes a first abutting member and a first clamping member. Both the first abutting member and the first clamping member are perpendicular to the flipping shaft. The first abutting member is fixedly connected to the fixed plate, and the first clamping member is slidably connected to the fixed plate. The first clamping members on the fixed plate are all driven by a first telescopic cylinder so that the fin plate can be clamped between the first abutting member and the first clamping member.

[0011] The second clamp is located on one side of the fixed plate. The second clamp includes a second abutment and a second clamping member. Both the second abutment and the second clamping member are parallel to the flipping axis. The second abutment is fixedly connected to the fixed plate, and the second clamping member is slidably connected to the fixed plate. The second clamping member is driven by a second telescopic cylinder so that the connecting plate can be clamped between the second abutment and the second clamping member. One side of the connecting plate abuts against one end of the fin plate.

[0012] The first and second clamps of the two fixed plates are arranged in a mirror image, and the second clamp is located in the middle of the pressure table.

[0013] Furthermore, a first drive rod and a second drive rod are provided on the side of the fixing plate facing the pressure table.

[0014] The first drive rod is slidably connected to the fixed plate, and the output shaft of the first telescopic cylinder is drivenly connected to the first drive rod, so that the first drive rod moves along the axial direction of the flipping shaft; the fixed plate is provided with a first sliding groove, the number of the first sliding groove is the same as the number of the first clamping member, and the bottom of the first clamping member is fixedly connected to the first drive rod through the first sliding groove, so that under the drive of the first telescopic cylinder, the first clamping member can move toward or away from the first abutting member;

[0015] The second drive rod is slidably connected to the fixed plate, and the output shaft of the second telescopic cylinder is drivenly connected to the second drive rod so that the second drive rod moves in a direction perpendicular to the flipping axis; the fixed plate is provided with a second sliding groove, and the bottom of the second clamping member is fixedly connected to the second drive rod through the second sliding groove so that the second clamping member can move toward or away from the second clamping member under the drive of the second telescopic cylinder.

[0016] Furthermore, each of the pressure plates is provided with an anti-tilting mechanism, which is located at the end of the pressure plate away from the flipping axis. The anti-tilting mechanism includes a fixed shell, a limiting member, and a drive motor. One end of the fixed shell is fixedly connected to the pressure plate, and a slider is provided at the end of the fixed shell away from the pressure plate. The slider is slidably disposed within the fixed shell. One end of the limiting member is slidably inserted through the fixed shell and fixedly connected to the slider. The drive motor is fixedly disposed within the fixed shell and is used to drive the slider so that the limiting member can extend out of the fixed shell or retract into the fixed shell. When the limiting member can extend out of the fixed shell, it can abut against the pressure table.

[0017] Furthermore, a support rod and a threaded rod are provided inside the fixed shell. The two ends of the support rod are fixedly connected to the fixed shell, and the support rod slides through the slider. The two ends of the threaded rod are rotatably connected to the fixed shell, and the threaded rod is threaded through the slider. The output shaft of the drive motor is connected to the threaded rod through a gear set.

[0018] Furthermore, the assembly platform is fixedly provided with a bracket, and a first infrared sensor and a second infrared sensor are sequentially arranged along the height direction on the bracket. The first infrared sensor and the second infrared sensor are electrically connected to the controller. The first infrared sensor is used to sense whether the pressure table has been flipped into place, and the second infrared sensor is used to sense whether the pressure plate has been pressed down into place.

[0019] Furthermore, a first limit switch and a second limit switch are respectively fixedly installed on the inner walls of both sides of the fixed shell along the moving direction of the slider, and the slider can press down the first limit switch or the second limit switch. The first limit switch and the second limit switch are respectively electrically connected to the drive motor through the controller. After the controller obtains the signal of flipping into place through the first infrared sensor, the controller controls the drive motor to rotate so that the limiting member passes through the fixed shell.

[0020] Furthermore, the fixed plate at the end away from the flipping shaft is an adjusting plate. The adjusting plate is slidably connected to the pressure table via a slide rail. Several adjusting holes are provided on both sides of the adjusting plate. The pressure table is provided with positioning holes. Positioning bolts are provided in the positioning holes. The positioning bolts can slide through different adjusting holes and then be threaded into the positioning holes to adjust the distance between the two fixed plates.

[0021] The beneficial effects of this invention are:

[0022] 1. After fixing two comb-tooth steel plates onto the pressure platform, weld a dustproof plate onto the two comb-tooth steel plates to seal the gap between them. Place a buffer pad on one side of the dustproof plate, then cover the buffer pad with a buffer component. Weld a water guide channel onto one side of the buffer component, ensuring that the buffer component and water guide channel are positioned above one comb-tooth steel plate. Fix the fins and connecting plates onto the fixed plate using clamps and then weld them into fins. Use a tilting motor to drive the tilting shaft, causing the pressure platform to tilt and press against the pressure platform. Simultaneously, the fins of one fixed plate press against the buffer component, water guide channel, and corresponding comb-tooth steel plate, while the fins of the other fixed plate press against the dustproof plate and corresponding comb-tooth steel plate. By welding one fin to the water guide channel and corresponding comb-tooth steel plate, and welding the other fin to the dustproof plate and corresponding comb-tooth steel plate, an expansion joint component is formed. After releasing the clamps, reset the pressure platform using the tilting motor, and then remove the expansion joint component from the assembly platform using a crane. Because the buffer components and water guide channels are sandwiched between the dustproof plate and the fins, the buffer components and water guide channels can abut against the corresponding fins under the elastic force of the buffer pad, ensuring that the expansion joint components have a certain degree of elasticity and reducing noise generated when vehicles pass by. This invention enables the production of expansion joint components in one workstation, effectively improving the production efficiency of expansion joint components. Moreover, this invention can reduce the frequency of lifting parts, effectively avoiding the occurrence of safety accidents.

[0023] 2. Under the action of the second telescopic cylinder, the second drive rod drives the second clamping member to press against the second abutting member, so that the connecting plate can be clamped and fixed on the pressure table; under the action of the first telescopic cylinder, the first drive rod moves, so that the first clamping member can press against the first abutting member, thereby clamping the fin plate, and at the same time, one end of the fin plate abuts against one side of the connecting plate. By welding the fin plate and the connecting plate, a fin is formed. This invention enables rapid positioning and welding of the fin plate and the connecting plate, eliminating the need for manual positioning by workers, increasing the accuracy of welding the fin plate and the connecting plate, and improving the manufacturing efficiency of the fin.

[0024] 3. When the pressure table flips onto the bearing platform, the drive motor drives the slider to move, allowing the limiting component to pass through the fixed shell. When the hydraulic cylinder drives the pressure plate to descend, the limiting component can limit the end of the pressure table away from the flipping axis, preventing the pressure table from warping and ensuring that the pressure table can effectively compress the buffer pad.

[0035] Please also see Figures 1 to 5 A preferred embodiment of the hydraulic assembly system for bridge expansion joint components of the present invention includes an assembly platform 1 and a pressure-bearing platform 2 and a pressure-applying platform 3 disposed on the assembly platform 1.

[0036] like Figure 1 and Figure 2 As shown, the pressure platform 2 is fixedly mounted on the assembly platform 1. The pressure platform 2 is used to fix two comb-tooth steel plates 11. A dustproof plate 12 is welded to the two comb-tooth steel plates 11 on the pressure platform 2. A buffer 13 and a water guide trough 14 are placed on the dustproof plate 12. A buffer pad 131 is provided between the buffer 13 and the dustproof plate 12. The buffer 13 and the water guide trough 14 are welded to each other. The side of the water guide trough 14 away from the buffer 13 is welded to the corresponding comb-tooth steel plate 11. In this embodiment, the comb-tooth steel plates 11 are fixedly connected to the pressure platform 2 by screws 111. In this embodiment, the comb-tooth steel plates 11 are provided with through mounting holes 112, and the pressure platform 2 is provided with threaded holes. The screws 111 slide through the mounting holes 112 and are then threaded into the threaded holes. Preferably, the two comb-tooth steel plates 11 can be positioned by a positioning base plate to facilitate the fixing of the screws 111. The dustproof plate 12 is folded and equipped with positioning elements for positioning the buffer 13 and the water guide trough 14.

[0037] Pressure plates 4 are respectively provided on both sides of the assembly platform 1. The two ends of the pressure plates 4 are connected to the assembly platform 1 through hydraulic cylinders 41. A flipping shaft 31 is fixedly provided on one side of the pressure table 3. The two ends of the flipping shaft 31 are rotatably connected to the two pressure plates 4 respectively. The flipping shaft 31 is driven by a flipping motor 311 so that the pressure plates 4 can be flipped onto the pressure table 2.

[0038] Two fixing plates 32 are provided on one side of the pressure table 3. The side of the fixing plates 32 facing away from the pressure table 3 is provided with clamps for holding the wing plate 15 and the connecting plate 16. The wing plate 15 and the connecting plate 16 are welded to form a wing. After the pressure table 3 is flipped, it is pressed against the pressure table 2 by the hydraulic cylinder 41. The wing of one fixing plate 32 can press against the buffer 13, the water guide trough 14 and the corresponding comb plate 11. The wing of the other fixing plate 32 can press against the dustproof plate 12 and the corresponding comb plate 11. By welding one wing to the water guide trough 14 and the corresponding comb plate 11, and welding the other wing to the dustproof plate 12 and the corresponding comb plate 11, an expansion joint component is formed.

[0039] In this embodiment, after fixing two comb-tooth steel plates 11 onto the pressure platform 2, a dustproof plate 12 is welded onto the two comb-tooth steel plates 11 to seal the gap between the two comb-tooth steel plates 11. A buffer pad 131 is placed on one side of the dustproof plate 12, and then a buffer member 13 is placed on the buffer pad 131. A water guide channel 14 is welded onto one side of the buffer member 13, and the buffer member 13 and the water guide channel 14 are positioned above one comb-tooth steel plate 11. The wing plate 15 and the connecting plate 16 are fixed onto the fixing plate 32 using a clamp and then welded into a wing. The flipping motor 311 drives the flipping shaft 31, causing the pressure table 3 to flip and press against the pressure bearing table 2. Simultaneously, the fins of one fixed plate 32 press against the buffer member 13, the water guide channel 14, and the corresponding comb-tooth steel plate 11, while the fins of the other fixed plate 32 press against the dustproof plate 12 and the corresponding comb-tooth steel plate 11. By welding one fin to the corresponding comb-tooth steel plate 11 and the other fin to the dustproof plate 12 and the corresponding comb-tooth steel plate 11, an expansion joint component is formed. Under the elastic force of the buffer pad 131, the buffer member 13 and the water guide channel 14 can abut against the corresponding fins. After releasing the clamps, the pressure table 3 is reset by the flipping motor 311, and the expansion joint component can be moved out of the assembly platform 1 by a crane.

[0040] In this embodiment, the two comb-tooth steel plates 11 are connected on opposite sides of the wing by a connecting frame, and the two ends of the connecting frame are connected to the two comb-tooth steel plates 11 by screws and nuts.

[0041] Since the buffer 13 and the water guide 14 are sandwiched between the dustproof plate 12 and the fins, under the elastic force of the buffer pad 131, the buffer 13 and the water guide 14 can abut against the corresponding fins, ensuring that the expansion joint components have a certain elasticity and reducing the noise generated when vehicles pass by.

[0042] This embodiment enables the fabrication of expansion joint components at a single workstation, effectively improving the production efficiency of expansion joint components. Furthermore, this invention can reduce the frequency of lifting parts, effectively preventing safety accidents.

[0043] like Figure 3 and Figure 4 As shown, the clamp includes a first clamp and a second clamp. Several first clamps are arranged alternately along the axial direction of the flipping shaft 31. Each first clamp includes a first abutting member 511 and a first clamping member 512. Both the first abutting member 511 and the first clamping member 512 are perpendicular to the flipping shaft 31. The first abutting member 511 is fixedly connected to the fixing plate 32, and the first clamping member 512 is slidably connected to the fixing plate 32. The first clamping members 512 on the fixing plate 32 are all driven by the first telescopic cylinder 531 so that the fin plate 15 can be clamped between the first abutting member 511 and the first clamping member 512.

[0044] The second clamp is located on one side of the fixed plate 32. The second clamp includes a second abutment 521 and a second clamping member 522. Both the second abutment 521 and the second clamping member 522 are parallel to the flipping shaft 31. The second abutment 521 is fixedly connected to the fixed plate 32, and the second clamping member 522 is slidably connected to the fixed plate 32. The second clamping member 522 is driven by the second telescopic cylinder 532 so that the connecting plate 16 can be clamped between the second abutment 521 and the second clamping member 522, and one side of the connecting plate 16 abuts against one end of the fin plate 15.

[0045] The first and second clamps of the two fixed plates 32 are mirror images of each other, and the second clamp is located in the middle of the pressure table 3.

[0046] The side of the fixed plate 32 facing the pressure table 3 is provided with a first drive rod 541 and a second drive rod 542.

[0047] The first drive rod 541 is slidably connected to the fixed plate 32, and the output shaft of the first telescopic cylinder 531 is connected to the first drive rod 541 in a transmission manner, so that the first drive rod 541 moves along the axial direction of the flipping shaft 31; the fixed plate 32 is provided with a first sliding groove 321 through it, and the number of first sliding grooves 321 is the same as the number of first clamping members 512. The bottom of the first clamping member 512 is fixedly connected to the first drive rod 541 through the first sliding groove 321, so that under the drive of the first telescopic cylinder 531, the first clamping member 512 can move toward or away from the first abutting member 511;

[0048] The second drive rod 542 is slidably connected to the fixed plate 32, and the output shaft of the second telescopic cylinder 532 is drively connected to the second drive rod 542, so that the second drive rod 542 moves in a direction perpendicular to the flipping shaft 31; the fixed plate 32 is provided with a second sliding groove 322, and the bottom of the second clamping member 522 is fixedly connected to the second drive rod 542 through the second sliding groove 322, so that the second clamping member 522 can move toward or away from the second clamping member 522 under the drive of the second telescopic cylinder 532. In this embodiment, both the first telescopic cylinder 531 and the second telescopic cylinder 532 are controlled by the same hydraulic pump.

[0049] Under the action of the second telescopic cylinder 532, the second drive rod 542 drives the second clamping member 522 to press against the second abutting member 521, so that the connecting plate 16 can be clamped and fixed on the pressure table 3; under the action of the first telescopic cylinder 531, the first drive rod 541 moves, so that the first clamping member 512 can press against the first abutting member 511, thereby clamping the fin plate 15. At the same time, one end of the fin plate 15 abuts against one side of the connecting plate 16. By welding the fin plate 15 and the connecting plate 16, a fin is formed. This embodiment can quickly position and weld the fin plate 15 and the connecting plate 16 without the need for manual positioning by workers, which increases the accuracy of welding the fin plate 15 and the connecting plate 16, and improves the manufacturing efficiency of the fin.

[0050] like Figure 3 and Figure 4 As shown, the fixed plate 32 at the end away from the flipping shaft 31 is an adjustment plate. The adjustment plate is slidably connected to the pressure table 3 via the slide rail 8. Several adjustment holes 81 are provided on both sides of the adjustment plate. The pressure table 3 is provided with positioning holes 82. Positioning bolts 83 are provided in the positioning holes 82. The positioning bolts 83 can slide through different adjustment holes 81 and then be threaded into the positioning holes 82 to adjust the distance between the two fixed plates 32.

[0051] Since the adjusting plate is provided with several adjusting holes 81, the distance between the two fixed plates 32 can be adjusted by sliding the positioning bolt 83 through different adjusting holes 81 and then threading it into the positioning bolt 83, thereby producing fins of different specifications.

[0052] like Figure 1 and Figure 5 As shown, each pressure plate 4 is equipped with an anti-tilting mechanism. The anti-tilting mechanism is used to limit the tilting of the pressure table 3 away from the tilting shaft 31 when the hydraulic cylinder 41 applies pressure. The anti-tilting mechanism is located at the end of the pressure plate 4 away from the tilting shaft 31. The anti-tilting mechanism includes a fixed shell 6, a limiting member 61, and a drive motor 62. One end of the fixed shell 6 is fixedly connected to the pressure plate 4. A slider 63 is provided at the end of the fixed shell 6 away from the pressure plate 4. The slider 63 is slidably disposed inside the fixed shell 6. One end of the limiting member 61 is slidably inserted through the fixed shell 6 and fixedly connected to the slider 63. The drive motor 62 is fixedly disposed inside the fixed shell 6 and is used to drive the slider 63 so that the limiting member 61 can be inserted outside the fixed shell 6 or retracted into the fixed shell 6. When the limiting member 61 can be inserted outside the fixed shell 6, the limiting member 61 can abut against the pressure table 3.

[0053] The fixed housing 6 is provided with a support rod 64 and a threaded rod 65. The two ends of the support rod 64 are fixedly connected to the fixed housing 6, and the support rod 64 slides through the slider 63. The two ends of the threaded rod 65 are rotatably connected to the fixed housing 6, and the threaded rod 65 is threaded through the slider 63. The output shaft of the drive motor 62 is connected to the threaded rod 65 through a gear set.

[0054] In this embodiment, the output shaft of the drive motor 62 is provided with a first gear 621, and the end of the threaded rod 65 away from the limiting member 61 is fixedly sleeved with a second gear 622. The drive motor 62 drives the second gear 622 to rotate through the first gear 621, thereby driving the threaded rod 65. Under the drive of the threaded rod 65, the slider 63 moves along the support rod 64, so that the limiting member 61 can pass through the fixed shell 6 or retract into the fixed shell 6.

[0055] When the pressure table 3 flips onto the pressure bearing table 2, the drive motor 62 drives the slider 63 to move, so that the limiting member 61 can pass through the fixed shell 6. When the hydraulic cylinder 41 drives the pressure plate 4 to descend, the limiting member 61 can limit the end of the pressure table 3 away from the flipping shaft 31, avoiding the pressure table 3 from warping and ensuring that the pressure table 3 can effectively compress the buffer pad 131.

[0056] like Figure 1 and Figure 6 As shown, the assembly platform 1 is fixedly equipped with a bracket 7. A first infrared sensor 71 and a second infrared sensor 72 are sequentially arranged along the height direction on the bracket 7. The first infrared sensor 71 and the second infrared sensor 72 are electrically connected to the controller. The first infrared sensor 71 is used to sense whether the pressure platform 3 has been reversed into position, and the second infrared sensor 72 is used to sense whether the pressure plate 4 has been pressed down into position. In this embodiment, the controller is electrically connected to the tilting motor 311 and the hydraulic cylinder 41. When the controller receives a signal from the first infrared sensor 71, it controls the tilting motor 311 to stop and then controls the hydraulic cylinder 41 to shorten, so that after the pressure platform 3 has been tilted into position, the pressure plate 4 applies downward pressure to the pressure platform 3.

[0057] like Figure 5 As shown, a first limit switch 661 and a second limit switch 662 are fixedly installed on the inner walls of both sides along the moving direction of the slider 63 inside the fixed housing 6. The slider 63 can press down either the first limit switch 661 or the second limit switch 662. The first limit switch 661 and the second limit switch 662 are electrically connected to the drive motor 62 through the controller. After the controller obtains the signal of flipping into place through the first infrared sensor 71, the controller controls the drive motor 62 to rotate so that the limiting member 61 passes through the fixed housing 6. The controller in this embodiment is a PLC controller. When the slider 63 presses down the first limit switch 661, it proves that the limiting member 61 has extended into place, and the controller controls the drive motor 62 to stop; when the slider 63 presses down the second limit switch 662, it proves that the limiting member 61 has retracted into place, and the controller controls the drive motor 62 to stop.

[0058] The hydraulic assembly process of the bridge expansion joint components hydraulic assembly system is as follows:

[0059] After fixing the two comb-tooth steel plates 11 onto the pressure platform 2, the dustproof plate 12 is welded onto the two comb-tooth steel plates 11 to seal the gap between the two comb-tooth steel plates 11. The buffer pad 131 is placed on one side of the dustproof plate 12, and then the buffer element 13 is placed on the buffer pad 131. The water guide channel 14 is welded onto one side of the buffer element 13, so that the buffer element 13 and the water guide channel 14 are located above one comb-tooth steel plate 11. The buffer element 13 and the water guide channel 14 are welded to each other, and the side of the water guide channel 14 away from the buffer element 13 is welded to the corresponding comb-tooth steel plate 11.

[0060] The connecting plate 16 is clamped between the second clamping member 522 and the second abutting member 521 by the second telescopic cylinder 532, and the fin plate 15 is clamped between the first clamping member 512 and the first abutting member 511 by the first telescopic cylinder 531. At the same time, one end of the fin plate 15 abuts against one side of the connecting plate 16. The fin plate 15 and the connecting plate 16 are welded together to form a fin.

[0061] After the fin plate 15 and the connecting plate 16 are fixed on the fixing plate 32 by the clamp, they are welded into fins.

[0062] The flipping motor 311 drives the flipping shaft 31, causing the pressure table 3 to flip and press against the pressure table 2. At the same time, the fins of one fixed plate 32 press against the buffer 13, the water guide trough 14 and the corresponding comb steel plate 11, while the fins of the other fixed plate 32 press against the dustproof plate 12 and the corresponding comb steel plate 11.

[0063] After receiving a signal from the first infrared sensor 71, the controller stops the flipping motor 311 and simultaneously controls the drive motor 62 to rotate, causing the limiting member 61 to extend out of the fixed housing 6. When the slider 63 presses down the first limit switch 661, it indicates that the limiting member 61 has extended to the correct position, and the controller stops the drive motor 62. After receiving a signal from the first limit switch 661, the controller shortens the hydraulic cylinder 41, causing the wing and the comb-tooth steel plate 11 to be under pressure. By welding one wing to the corresponding comb-tooth steel plate 11 and welding the other wing to the dustproof plate 12 and the corresponding comb-tooth steel plate 11, an expansion joint component is formed.

[0064] After welding is completed, the controller controls the drive motor 62 to rotate. When the slider 63 presses down the second limit switch 662, it indicates that the limit member 61 has retracted into place, and the controller controls the drive motor 62 to stop. After receiving the signal from the second limit switch 662, the controller controls the first telescopic cylinder 531, the second telescopic cylinder 532, and the hydraulic cylinder 41 to reset. When the second infrared sensor 72 receives a change signal, the controller controls the tilting motor 311 to rotate, so that the pressure table 3 resets.
