DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 , an automatic welding device for ship lashings, comprising a flatbed trolley 1, the flatbed trolley 1 can be a human-powered trolley, but when used on a large ship, it is more convenient to use an electrically driven flatbed trolley 1, the flatbed trolley 1 is also provided with a storage space for carrying lashings and seats and other components, the flatbed trolley 1 is provided with a positioning structure, and the flatbed trolley 1 is provided with a welding assembly;

[0025] The positioning structure includes a support frame 2 fixedly connected to the flatbed vehicle 1, a connecting frame 3 is slidably connected to the support frame 2, a track groove is provided on the support frame 2 for cooperating with the connecting frame 3, the sliding track of the connecting frame 3 is not a straight line, specifically refer to the figure, and a positioning cone 4 is fixedly connected to the lower surface of the middle part of the connecting frame 3, a spherical wheel 5 is embedded at the lower end of the positioning cone 4, a pull rope 6 is fixedly connected to the support frame 2, and the pull rope 6 is fixedly connected to the upper end of the positioning cone 4;

[0026] In this design, the positioning cone 4 cooperates with the spherical wheel 5 to move on the deck, and after the positioning cone 4 moves to the circular hole position, the positioning cone 4 is inserted into the circular hole. At this time, the user adjusts the position of the flatbed truck 1 so that the positioning cone 4 is fully inserted into the circular hole to complete the positioning operation, which is convenient for the subsequent installation and welding of the binding parts.

[0027] The welding assembly includes a frame 7 slidably connected to the support frame 2, a placement frame 8 is arranged in the frame 7, a slide rail 9 is arranged in the placement frame 8, and a welding head 10 is arranged on the slide rail 9, and a driving arm 11 is fixedly connected to the welding head 10;

[0028] In this design, the placement rack 8 is used to place the tying pieces to be installed, and the slide rail 9 cooperates with the welding head 10 to limit the moving track of the welding head 10. On the other hand, it also makes it unnecessary to position the welding head 10 and the tying pieces, which facilitates the welding operation.

[0029] The flatbed vehicle 1 is also provided with a driving mechanism for welding components;

[0030] Based on the above design, when using this automatic welding device, the user places the lashing piece to be installed in the placement frame 8, and then drives the flatbed trolley 1 to move on the deck. After approaching the circular hole on the deck for installing the lashing piece, the position of the flatbed trolley 1 is adjusted so that the positioning cone 4 is inserted into the circular hole, and then the position of the flatbed trolley 1 is fine-tuned so that the positioning cone 4 is completely inserted into the circular hole. It should be noted that in this design, if the flatbed trolley 1 has a large deadweight, a sliding frame can be set on the flatbed trolley 1 to place the support frame 2. When the positioning cone 4 with a large deadweight is used, the position of the entire support frame 2 can be adjusted by positioning, which is more convenient for users to use;

[0031] After the positioning is completed, the user pushes the placement rack 8 to move. After the placement rack 8 is in contact with the pull rope 6, it drives the connecting rack 3 to move upward. Then the connecting rack 3 is in contact with the placement rack 8 and continues to move downward driven by the placement rack 8. After the placement rack 8 moves to the maximum stroke, the binding piece on the placement rack 8 is opposite to the circular hole. At this time, the binding piece on the placement rack 8 is placed in the circular hole, and then the driving assembly is used to drive the welding head 10 to move to weld the binding piece.

[0032] Further, the driving mechanism includes a driving motor 12 fixedly connected to the support frame 2, the output end of the driving motor 12 is fixedly connected to a driving gear 13, the placement frame 8 is rotatably connected to a driven shaft 14, the upper end of the driven shaft 14 is fixedly connected to a driven gear 15 meshing with the driving gear 13, and the lower end of the driven shaft 14 is fixedly connected to the driving arm 11;

[0033] In the initial state, the driving gear 13 and the driven gear 15 are not in a meshing state, but after the placement rack 8 is moved, the driving gear 13 and the driven gear 15 are meshed. When the driven shaft 14 rotates, the driving arm 11 is used to drive the welding head 10 to move around the binding piece, thereby finally completing the purpose of welding the binding piece.

[0034] Further, the placement rack 8 includes a main body 81, the lower surface of the main body 81 is rotatably connected to a baffle 82, and the baffle 82 is provided with a clearance opening 83, the lower end of the main body 81 is rotatably connected to a limit rod 84 through a spring shaft, and the limit rod 84 is fixedly connected to a stopper 85 near the side wall of the baffle 82, and the lower end of the limit rod 84 is also fixedly connected to an inclined rod 86;

[0035] In this design, the baffle 82 is used to support the binding member under normal conditions, and the block 85 on the limit rod 84 is against the lower surface of the baffle 82. When the placement rack 8 is in the initial state, the baffle 82 cannot rotate freely. When the placement rack 8 moves toward the circular hole, after the inclined rod 86 is against the deck, it can drive the limit rod 84 to rotate. At this time, the baffle 82 also rotates, and finally causes the binding member to fall downward. At this time, even if the binding member is not facing the circular hole, as the placement rack 8 continues to move, the binding member can slide on the clamp until the binding member falls into the circular hole. The relative position of the welding head 10 and the binding member only changes in the longitudinal direction, which has no effect on the subsequent welding operation.

[0036] Furthermore, the frame 7 is fixedly connected to an inclined slide 16, and horizontal grooves 17 are provided at both ends of the slide 16. A slider matching the slide 16 is fixedly connected to the main body 81. When the main body 81 slides, it moves downward while approaching the circular hole, and after moving to the maximum stroke, the driving gear 13 engages with the driven gear 15.

[0037] Furthermore, a spring rod 18 is disposed at the lower end of the main body 81 , and a gasket is fixedly connected to the lower end of the spring rod 18 . In this design, the spring rod 18 is provided in conjunction with the gasket to reduce shock for the main body 81 .

[0038] Furthermore, the flatbed vehicle 1 is fixedly connected with an electric push rod 19, and the movable end of the electric push rod 19 is slidably connected with the main body 81;

[0039] Based on the above design, the electric push rod 19 can be used to drive the main body 81 to move without manually pushing the main body 81, thereby further improving the automation level and facilitating user operation.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
