[0002] Steel structure processing refers to the process of processing steel into components or structures required for buildings, bridges, ships, etc., through processes such as cutting, welding, drilling, and bending.

[0003] T-shaped steel components are required in the current ship assembly process. The welding of existing T-shaped steel components is generally carried out by manual welding. However, manual welding is slow and inefficient, especially in large-scale production. Long-term work can easily lead to fatigue and affect the welding quality. At the same time, the welding quality is highly dependent on the welder's skill level and experience. Insufficient skills may lead to problems such as uneven welds, porosity, and slag inclusions. Summary of the Invention

[0004] The purpose of this utility model is to provide a welding device for marine steel structures, which solves the problem of low efficiency in large-scale production caused by the manual welding of existing T-shaped steel components.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a welding device for marine steel structures, comprising a workbench with several transmission rollers rotatably connected inside. A support frame is provided on the lower surface of the workbench, and a clamping seat is installed on the upper surface of the workbench. A welding torch is installed inside the clamping seat. Side plates are installed on both sides of the workbench, and vertical plates are installed on the upper surfaces of both side plates. A limiting structure is provided between the two vertical plates, including a connecting plate. A baffle is installed on one side of the connecting plate, and a groove is formed on the lower surface of the connecting plate. A bidirectional screw is rotatably connected to the inner surface of the groove. One end of the bidirectional screw passes through the baffle and extends outward. A sliding plate is threaded onto the outer surface of the bidirectional screw. Limiting plates are provided on the lower surfaces of both sliding plates. One vertical plate is fixedly installed to the baffle by bolts, and the other vertical plate is fixedly installed to the connecting plate by bolts. The upper ends of both sliding plates are located inside the groove, and both sliding plates move along the axis of the groove.

[0007] Furthermore, a cylinder is mounted on the outer surface of the limiting plate, a cover plate is mounted on the end of the cylinder away from the limiting plate, a slider is slidably connected inside the cylinder, a spring is mounted on one end of the slider, and the other end of the spring is mounted on the inner surface of the cylinder.

[0008] Furthermore, a column is installed at the end of the slider away from the spring, and one end of the column passes through the cover plate and extends outward.

[0009] Furthermore, one of the vertical plates has a mounting base on its outer surface, a drive motor is installed inside the mounting base, and a drive wheel is installed at the output end of the drive motor.

[0010] Furthermore, a connecting rod is installed at one end of the bidirectional screw, and a driven wheel is installed on the outer surface of the connecting rod. The driving wheel is connected to the driven wheel via a belt.

[0011] Furthermore, the lower surface of the side plate is provided with a reinforcing plate, and the other end of the reinforcing plate is installed on the outer surface of the workbench by bolts.

[0012] This utility model has the following beneficial effects:

[0013] (1) In this utility model, steel plate A is laid horizontally on the transmission roller to ensure that steel plate A is stable and in good contact with the transmission roller. Then, steel plate B is placed vertically on steel plate A to ensure that the contact surface of steel plate B is perpendicular to that of steel plate A. The position of steel plate B is adjusted so that it is aligned with the welding edge of steel plate A. By rotating the double screw, the rotation of the double screw causes the slide plate to move along the slide groove, which drives the two limiting plates to approach steel plate A so that they contact the outer surface of steel plate A. By starting the welding gun, welding is performed along the contact edge of steel plate A and steel plate B. During the welding process, the slow rotation of the transmission roller causes steel plate A and steel plate B to move synchronously to ensure that the welding is continuous and uniform, achieving a better welding effect and improving the welding efficiency.

[0014] (2) When the steel plate moves, the slight offset or vibration caused by the movement of the transmission roller can be automatically compensated by the elastic expansion and contraction of the column to maintain the uniformity of the clamping force.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a welding device for marine steel structures, including a workbench 1. Several transmission rollers 2 are rotatably connected inside the workbench 1. A support frame 101 is provided on the lower surface of the workbench 1. Clamping seats 3 are installed on both sides of the upper surface of the workbench 1. A welding torch 4 is installed inside the clamping seats 3. Side plates 5 are installed on both sides of the workbench 1. Vertical plates 6 are installed on the upper surface of both side plates 5. A limiting structure 7 is provided between the two vertical plates 6. The limiting structure 7 includes a connecting plate 701. A baffle 702 is installed on one side of the connecting plate 701. A groove is formed on the lower surface of the connecting plate 701. The slide groove has a bidirectional screw 703 rotatably connected to its inner surface. One end of the bidirectional screw 703 passes through the baffle 702 and extends outward. The outer surface of the bidirectional screw 703 is threaded with a sliding plate 704. The lower surfaces of the two sliding plates 704 are provided with limiting plates 705. One vertical plate 6 is fixedly installed to the baffle 702 by bolts, and the other vertical plate 6 is fixedly installed to the other end of the connecting plate 701 by bolts. The upper ends of the two sliding plates 704 are located inside the slide groove. The two sliding plates 704 move in opposite directions along the axis of the slide groove under the drive of the bidirectional screw 703.

[0025] One of the vertical plates 6 has a mounting base 601 on its outer surface. A drive motor 8 is installed inside the mounting base 601. A drive wheel 9 is installed at the output end of the drive motor 8.

[0026] A connecting rod 10 is installed at one end of the bidirectional screw 703, and a driven wheel 11 is installed on the outer surface of the connecting rod 10. The driving wheel 9 is connected to the driven wheel 11 through a belt 12.

[0027] A cylinder 706 is mounted on the outer surface of two limiting plates 705 facing each other. A cover plate 707 is mounted on the end of the cylinder 706 away from the limiting plates 705. A slider 708 is slidably connected inside the cylinder 706. A spring 709 is mounted on one end of the slider 708, and the other end of the spring 709 is mounted on the inner surface of the cylinder 706.

[0028] A column 7010 is installed at the end of the slider 708 away from the spring 709. One end of the column 7010 passes through the cover plate 707 and extends outward. A through hole larger than the outer diameter of the column 7010 is opened on the cover plate 707. The outer diameter of the slider 708 is larger than the diameter of the through hole, thereby preventing the slider 708 from coming out of the cylinder 706.

[0029] When the limiting plate 705 contacts the edge of the steel plate A, the outer surface of the column 7010 contacts the outer surface of the steel plate B. When the steel plate B moves, the slight offset or vibration caused by the movement of the transmission roller 2 can be automatically compensated by the elastic expansion and contraction of the column 7010 to maintain the uniformity of the clamping force.

[0030] The lower surface of the side plate 5 is provided with a reinforcing plate 501, and the other end of the reinforcing plate 501 is installed on the outer surface of the workbench 1 by bolts;

[0031] The reinforcing plate 501 is fixed between the workbench 1 and the side plate 5 by bolts, forming a triangular or trapezoidal support structure, which significantly improves the bending and torsional resistance of the side plate 5.

[0032] Preferably, in this embodiment, the clamping seat 3 and the welding torch 4 are rotatably connected by a screw. When it is necessary to fix the rotation angle, the connection position of the clamping seat 3 and the welding torch 4 can be clamped by tightening nuts at both ends of the screw to fix the angle of the clamping seat 3 and the welding torch 4.

[0033] In use, first install the conveyor roller 2 to the external drive equipment. Lay steel plate A horizontally on the conveyor roller 2, ensuring it is stable and in good contact with the roller. Then, place steel plate B vertically on steel plate A, ensuring the contact surfaces of steel plate B and steel plate A are perpendicular. Adjust the position of steel plate B to align it with the welding edge of steel plate A. Next, adjust the clamping seat 3 so that the output end of the welding torch 4 is located at the welding point between steel plate A and steel plate B. Then, start the drive motor 8, causing it to drive the drive wheel 9 to rotate. The drive wheel 9, through the belt 12, drives the driven wheel 11... When the connecting rod 10 rotates, it drives the bidirectional screw 703 to rotate. The rotation of the bidirectional screw 703 causes the slide plate 704 to move along the slide groove and drive the limiting plate 705 to move closer to the steel plate A, so that it contacts the outer surface of the steel plate A. By starting the welding gun 4, welding is performed along the contact edge between the steel plate A and the steel plate B. During the welding process, by starting the external driving equipment, the driving equipment drives the transmission roller 2 to rotate. Through the slow rotation of the transmission roller 2, the steel plate A and the steel plate B move synchronously, ensuring that the welding is continuous and uniform, achieving a better welding effect, and improving the welding efficiency.
