[0002] During the quay crane construction process, the machine room, housing control equipment, is the core of the entire quay crane control system.

[0050] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0051] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0052] Furthermore, the term "one embodiment" or "embodiment" in this application refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0053] The utility model proposes a welding device for plated steel plates, comprising a fixed gantry 9, a plate support frame, a coating removal mechanism, and a welding mechanism. Figure 1 、 Figure 2 The fixed gantry 9 is used as the main structure, such as Figure 3 As shown, the longitudinal direction is aligned with the weld seam. A plate support frame is positioned below the gantry 9, carrying the steel plates to be welded. A coating removal mechanism is suspended from the gantry 9 and moves back and forth in a first direction to remove the coating from the weld seam on the steel plates to be welded (e.g., removing the zinc layer from galvanized corrugated sheet metal). The welding mechanism is suspended from the gantry 9, aligned with the coating removal mechanism along the first direction, and positioned behind the coating removal mechanism to weld the steel plates to be welded along the weld seam. The first direction is parallel to the weld seam, and the forward direction is the welding forward direction in the first direction.

[0054] The coating removal mechanism removes the coating from the plated steel plate before welding, which can effectively solve the problem of large welding spatter of the plated steel plate.

[0055] A welding track is provided on the top of the gantry 9, on which a first driver 23 is suspended. The first driver 23 drives the coating removal mechanism and / or the welding mechanism to move forward and backward along the welding track. Considering the equipment running length and pipeline layout, the first driver 23 is placed on a motion platform and the coating removal mechanism and the welding mechanism can be controlled independently. Figure 4 As shown, the coating removal mechanism includes a first welding gun 24 suspended on the welding track, and the first welding gun 24 removes the coating on the steel plate to be welded by laser. The welding mechanism includes a second welding gun 21 and a wire feeder 22 suspended on the welding track. The second welding gun 21 is arranged along the first direction with the first welding gun 24, and is located behind the first welding gun 24, and welds the steel plate to be welded by laser. The wire feeder 22 is arranged along the second direction with the second welding gun 21, and the second direction is a direction perpendicular to the first direction on the horizontal plane. Compared with manual carbon dioxide gas shielded welding, laser welding has low unit heat input, small thermal deformation, large weld depth-to-width ratio, high welding speed, and weld strength is generally higher than the base material. Laser welding is a single-sided processing, has good adaptability to complex structures, and can effectively remove the coating and complete welding. As Figure 5 As shown, a weld tracking mechanism 27 is also suspended on the welding track to scan and identify the weld position. The first driver 23 drives the weld tracking mechanism 27 to move back and forth along the welding track synchronously with the coating removal mechanism and the welding mechanism.

[0056] The plate support frame is also provided with a pressing mechanism, see Figure 6The clamping mechanism is located below the welding track and includes two beams 30 fixedly mounted on both ends of the plate support frame, an upper pressure module 10, a lower support module 14, a first cylinder 15, a pressure arm 11 and a second cylinder 12. The two beams 30 are spaced apart along the second direction. There are multiple pressure arms 11, which are horizontally arranged between the two beams 30 to press the surface of the steel to be welded. The pressure arm 11 is connected to the beam 30 through the second cylinder 12. The second cylinder 12 controls the up and down movement of the pressure arm 11. The lower support module 14 and the upper pressure module 10 are mounted between the two beams 30 through the first cylinder 15 to clamp the weld overlap position of the steel to be welded. The first cylinder 15 is fixed on the plate support frame at the bottom and supports the lower support module 14 at the top to control the up and down movement of the lower support module 14. When the steel plate to be welded is ready for welding, the lower support module 14 is lifted and fits the steel plate to be welded, and the upper pressure module 10 is used to clamp the workpiece as a whole. The pressure arm 11, upper pressure module 10, and lower support module 14 work together to close the weld overlap position, fix the steel plates to be welded, and ensure that the weld fit at the laser weld meets the laser welding requirements. To facilitate control and adjustment, the upper pressure module 10 and the lower support module 14 both adopt a segmented structure, that is, segmented clamping along the weld direction, and each lower support module 14 is individually controlled by an independent cylinder. The shape of the pressure module 10 and the lower support module 14 are designed according to the shape and structure of the steel to be welded. For example, for corrugated plates, the weld overlap position is concave, and the corresponding groove should also be opened on the top of the lower support module 14 as a welding groove, see Figure 7 、 Figure 8 The upper pressing module 10 can be designed to be a downward convex shape to fit the weld overlap position of the clamped corrugated plate, so that the steel plate at the weld overlap position is placed in the groove.

[0057] A horizontally fixed support arm 28 is mounted on one end of the crossbeam 30, supporting one side of the steel plate to be welded. A horizontally sliding support arm 13 is mounted on the other end of the crossbeam 30, moving the other side of the steel plate to be welded. A second actuator 16 is fixed to the crossbeam 30, driving the support arm 13 to move back and forth along the crossbeam 30. This actuator drives the support arm 13, which in turn moves the steel plate to be welded toward the support arm, achieving single-sided alignment of the long steel plate, ensuring single-sided straightness and ensuring the flatness of the entire plate after welding.

[0058] The top of the gantry 9 is also provided with a plurality of plate moving rails 29, which are all arranged along the second direction, and a plate moving mechanism is hung on the plate moving rails 29, see Figure 9, the plate moving mechanism slides along the plate moving track 29. The plate moving mechanism includes a third driver 8 and a guide column 7 suspended on the plate moving track 29. A horizontally arranged suction cup 1 is connected below the guide column 7. The lower middle position of the suction cup 1 is concave to form a hollow cavity 4. A plurality of air pipes 5 are fixed above the suction cup 1. One end of the air pipe 5 is connected to the hollow cavity 4, and the other end is connected to the third cylinder 6. Among them, the third cylinder 6 extracts the air in the hollow cavity 4 through the air pipe 5, so that the suction cup 1 adsorbs the steel plate to be welded, and the third driver 8 drives the suction cup 1 to move along the plate moving track 29 and / or drives the suction cup 1 to move up and down along the guide column 7.

[0059] The suction cup 1 is also equipped with a pressure sensor 3 and a contour block 2. The pressure sensor 3 measures the suction cup 1's grip on the steel plate to be welded, ensuring that the grip is sufficient to lift the plate. The contour blocks 2 are positioned around the suction cup 1 and are designed to conform to the surface of the plate to be welded. This prevents air leakage around the suction cup 1 when it is gripping uneven plates, which could cause the plate to fail to lift.

[0060] The plate support frame is also equipped with a conveyor mechanism, which includes multiple conveyor chains 17 and several pillars supporting the conveyor chains 17. The pillars are arranged in an array. The conveyor chains 17 are mounted on the pillars, with one end located below the gantry 9 and the other end extending in the second direction. This conveyor chain 17 conveys the steel plates, completing the movement of the steel plates throughout the welding production line and also enabling continuous welding of multiple steel plates. The conveyor chain 17 in one embodiment of the present invention can automatically weld lap welds of steel plates with a length of 3.5 to 12 meters.

[0061] In one embodiment of the present invention, the first driver 23, the second driver 16, and the third driver 8 are all motors. The first cylinder 15, the second cylinder 12, and the third cylinder 6 are all hydraulic cylinders.

[0062] To achieve full automation of the welding equipment, a controller (such as a PLC) can also be provided to automatically control the first driver 23, the second driver 16, the third driver 8, the first cylinder 15, the second cylinder 12, the third cylinder 6, and the pressure sensor 3, thereby automating the conveying of the steel plates to be welded, welding, suction cup adsorption, and automatic adjustment of the clamping pressure. Connecting the weld tracking mechanism 27 to the controller can also provide real-time feedback on the identified weld position. The controller then adjusts the position of the coating removal mechanism and the welding mechanism based on the feedback to prevent weld deviation.

[0063] Welding equipment is an important technical basis for ensuring the quality of the overlap welds in the enclosure room and the smooth assembly. Since the welds are long and the welding gap is required to be small during the entire welding process, it is necessary to ensure that the clamping mechanism is tightly fitted to the overlap position of the weld before welding. Only then can the laser be used to remove the coating and then perform thin plate laser welding.

[0064] The following uses the welding of galvanized corrugated sheet metal using the above welding equipment as an example to explain the operation steps of the above welding equipment:

[0065] 1. Use the plate moving mechanism to move the galvanized corrugated plate to the welding position.

[0066] Specifically, the controller controls the third actuator 8 to move the plate transfer mechanism along the plate transfer track 29 to the top of the corrugated plate sheet. Once in position, the third actuator 8 drives the suction cup 1 to descend along the guide post 7 until the contour block 2 and the suction cup 1 are in contact with the surface of the corrugated plate sheet. Once contact is complete, the third cylinder 6 draws air through the air pipe 5 to create a vacuum within the hollow cavity 4. The pressure sensor 3 then determines whether the pressure has reached a suitable value for suction and lifting. Once the pressure sensor 3 reaches the appropriate value, the corrugated plate sheet is completely adsorbed and loaded. The third actuator 8 then causes the suction cup 1, holding the corrugated plate sheet, to ascend along the guide post 7, completing the transfer of the corrugated plate sheet along the plate transfer track 29.

[0067] 2. Overlap of corrugated sheets.

[0068] Specifically, the corrugated plate is moved to the welding area (even if the weld position is directly below the welding mechanism and the coating removal mechanism) by relying on the conveying chain 17 of the conveying mechanism, and then combined with the plate moving mechanism, the steel plates to be welded are overlapped.

[0069] 3. Align the two corrugated plates.

[0070] Specifically, the second driver 16 drives the moving arm 13 to move, thereby pushing the corrugated plate to move toward the arm. The corrugated plate is aligned to one side, and a baffle 18 is provided on one side of the plate support frame to press against one side of the plate to achieve unilateral alignment of the plate and ensure the flatness of the entire plate after welding.

[0071] 4. Use the pressing mechanism to press the overlapping positions of the corrugated plates.

[0072] Specifically, after the corrugated sheet is pushed to the welding area and aligned, the lower support module 14 is lifted and fixed in position by the first cylinder 15, so that the overlapped weld seam of the sheet is located in the groove of the lower support module 14. The segmented upper pressing module 10 presses down to complete the sheet bonding. The second cylinder 12 then presses the pressing arm 11 down on the surface of the corrugated sheet, completely fixing the workpiece and tightening the overlapped weld seam, making the overlapped corrugated sheet more secure and reducing the gap between the overlapped weld seams to ensure that the welding gap meets the requirements.

[0073] 5. Dezincify and weld the corrugated plates.

[0074] Specifically, the first driver 23 moves the coating removal mechanism and welding mechanism to the welding starting position, and the weld tracking mechanism 27 descends to locate and track the weld. According to the program settings, the first welding gun 24 is first activated and moves forward to complete the laser dezincification operation. The weld tracking mechanism 27 scans the weld position in real time and feeds it back to the controller. The second welding gun 21 moves behind the first welding gun 24 to the dezincified weld position and begins welding. Simultaneously, the wire feeder 22 feeds the wire, accurately delivering it to the designated welding position according to the set speed, shape, and length. The controller controls the first driver 23 to drive the dezincification and welding mechanisms to complete the dezincification and welding process according to the program settings, allowing dezincification and laser welding to proceed synchronously. Throughout the process, the weld tracking mechanism 27 monitors the weld position in real time to prevent weld deviation.

[0075] 6. Move the welded corrugated sheet out of the welding area.

[0076] Specifically, it is transported by the transmission chain 17 and the single-side alignment is completed using the transfer arm 13.

[0077] 7. Repeat the above-mentioned actions of moving plates, overlapping, aligning, pressing and welding to overlap several corrugated plates until the predetermined welding task is completed to form the wall of the machine room.

[0078] Partial adhesion in the dezincified areas reduces the precision requirements for subsequent welding. Dezincified welds are characterized by a full, beautifully formed weld with virtually no spatter. Welding speeds can reach 1800 mm / min, a 140% increase over manual welding speeds of 750 mm / min.
