The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0019] As Figure 1 shown, the utility model discloses a welding device for a marine ladder outfitting part, which includes a main body bracket 1, a welding mechanism and a traveling mechanism. The main body bracket 1 is fixed on the traveling mechanism. The traveling mechanism is slidably arranged on one side plate 2 of the ladder outfitting part and can travel along the length direction of the side plate 2. The welding mechanism is arranged on the main body bracket 1. The welding mechanism includes a welding torch 3, a welding torch bracket 4 and an electric telescopic rod 5. The welding torch 3 is fixed on the welding torch bracket 4. The welding torch bracket 4 is arranged on the electric telescopic rod 5 and is driven by the electric telescopic rod 5 to expand and contract along the width direction of the pedal 6 of the ladder outfitting part. The electric telescopic rod 5 is fixed on the main body bracket 1.

[0020] The main body bracket 1 is a V-shaped bracket. The included angle of the V-shaped bracket is complementary to the included angle between the ladder outfitting part and the horizontal plane. Through the angle design of the V-shaped bracket of the main body bracket 1, the welding mechanism part can match the width direction of the pedal 6, while the traveling mechanism can match the length direction of the side plate 2.

[0021] A bracket angle adjusting mechanism is provided at the upper end of the main body bracket 1. As Figure 2 shown, the bracket angle adjusting mechanism includes an adjusting bracket 7, a screw pin shaft 8 and a locking nut 9. The lower end of the adjusting bracket 7 is hinged to the upper end of the main body bracket 1 through the screw pin shaft 8. One end of the screw pin shaft 8 passes through the hinge hole at the hinged part of the adjusting bracket 7 and the main body bracket 1 and is locked and fixed by the locking nut 9. The other end of the screw pin shaft 8 is provided with a screw head structure to cooperate with the locking nut 9 to clamp on both sides of the hinged position of the adjusting bracket 7 and the main body bracket 1. A conical plastic shell is provided on the outer side of the locking nut 9, and stripes for increasing friction are provided on the outer side of the conical plastic shell, which is convenient for manually rotating the locking nut 9 in the conical plastic shell, so as to adjust the angle between the adjusting bracket 7 and the main body bracket 1 through the locking and loosening of the locking nut 9. The main purpose of adjusting this angle is to adjust the distance between the welding torch 3 and the weld of the pedal 6.

[0022] The welding torch bracket 4 is connected to the end of the electric telescopic rod 5 through a welding torch angle adjusting mechanism 10. As Figure 3As shown, the welding gun angle adjustment mechanism 10 includes a first cylindrical bracket 11, a second cylindrical bracket 12, a telescopic rod 13, a piston 14 and a piston return spring 15. A first tooth pattern is arranged on the outer side of one end of the first cylindrical bracket 11, and a second tooth pattern is arranged on the outer side of one end of the second cylindrical bracket 12. The first tooth pattern is meshed with the second tooth pattern. The telescopic rod 13 is arranged along the axial direction of the first cylindrical bracket 11 or the second cylindrical bracket 12. One end of the telescopic rod 13 is fixed to the end surface center of one end of the first cylindrical bracket 11. The piston 14 is fixed to the other end of the telescopic rod 13. A piston cavity 16 matching the piston 14 is opened at one end of the second cylindrical bracket 12. The piston 14 is slidably arranged in the piston cavity 16 and can slide in the piston cavity 16 along the axial direction of the second cylindrical bracket 12. The piston return spring 15 is sleeved on the outer side of the telescopic rod 13, one end of the piston return spring 15 abuts against the inner wall of one end of the piston cavity 16, and the other end of the piston return spring 15 abuts against one side of the piston 14. When the first column bracket 11 is pulled to the left, the piston 14 slides to the left in the piston chamber 16 and compresses the piston return spring 15. When the first column bracket 11 moves to the left for a distance, the first gear and the second tooth pattern are staggered, and the angle of the first column bracket 11 can be freely rotated. After the angle of the first column bracket 11 is adjusted, the first column bracket 11 is released. Under the action of the piston return spring 15, the first column bracket 11 is reset to the right and the first tooth pattern and the second tooth pattern are re-engaged to position and fix the angle of the first column bracket 11. Since the bracket angle adjustment mechanism will also change the angle of the welding gun 3 when adjusting the distance of the welding gun 3, after adjusting the distance of the welding gun 3, the welding gun angle adjustment mechanism 10 is required to readjust the angle of the welding gun relative to the weld of the pedal 6.

[0023] The traveling mechanism includes a traveling fixed bracket 17, a traveling movable bracket 18, two fixed traveling wheels 19, two movable traveling wheels 20, a driving mechanism, a first slide rod 21, a second slide rod 22, a first telescopic spring 23, and a second telescopic spring 24. The two fixed traveling wheels 19 are respectively rotatably arranged at both ends of the traveling fixed bracket 17, and the two fixed traveling wheels 19 are rollingly arranged on the upper side edge of one side plate 2 of the ladder fitting. The two movable traveling wheels 20 are respectively rotatably arranged at both ends of the traveling movable bracket 18, and the two movable traveling wheels 20 are rollingly arranged on the lower side edge of one side plate 2 of the ladder fitting. The first slide rod 21 and the second slide rod 22 are arranged perpendicular to the traveling fixed bracket 17. One end of the first slide rod 21 and the second slide rod 22 is fixed on the traveling fixed bracket 17. Two through holes respectively matching the first slide rod 21 and the second slide rod 22 are formed on the traveling movable bracket 18. The traveling movable bracket 18 is slidably arranged on the first slide rod 21 and the second slide rod 22 through the two through holes. Limit blocks 25 are arranged at the other ends of the first slide rod 21 and the second slide rod 22. The first telescopic spring 23 is sleeved outside the first slide rod 21 and is located between the traveling movable bracket 18 and the limit block 25. The second telescopic spring 24 is sleeved outside the second slide rod 22 and is located between the traveling movable bracket 18 and the limit block 25. One fixed traveling wheel 19 is connected to the driving mechanism and is driven by the driving mechanism. When in use, the traveling movable bracket 18 is pushed along the direction away from the traveling fixed bracket 17 along the first slide rod 21 and the second slide rod 22, so that the distance between the traveling movable bracket 18 and the traveling fixed bracket 17 is large enough. During the pushing process, the first telescopic spring 23 and the second telescopic spring 24 are compressed. Then, the two fixed traveling wheels 19 and the two movable traveling wheels 20 are respectively placed on the upper and lower sides of the side plate 2, and the traveling movable bracket 18 is released, so that the traveling movable bracket 18 is reset to the other side under the action of the first telescopic spring 23 and the second telescopic spring 24, thereby clamping the two fixed traveling wheels 19 and the two movable traveling wheels 20 on the upper and lower sides of the side plate 2 respectively to complete the fixation of the traveling mechanism.

[0024] The driving mechanism includes a reducer 26 and a motor 27. One fixed traveling wheel 19 is connected to the output shaft of the reducer 26 and is driven by the reducer 26. The input shaft of the reducer 26 is connected to the motor 27 and is driven by the motor 27. After being decelerated by the reducer 26, the motor 27 drives the fixed traveling wheel 19 to travel on the side plate 2.

[0025] Annular grooves are arranged on the outer side surfaces of the two fixed traveling wheels 19 and the two movable traveling wheels 20. The width of the annular grooves matches the thickness of the two side plates 2 of the ladder fitting. The fixed traveling wheels 19 and the movable traveling wheels 20 are clamped on the edges of the side plates 2 of the ladder fitting through the annular grooves.

[0026] The utility model provides a welding device for marine ladder outfitting parts. Through a traveling mechanism with a unique structure, the welding device can be clamped on the side plate of the ladder outfitting parts and travel along the length direction of the side plate to realize the welding of pedals at different positions. After the welding device travels to the corresponding pedal position, the distance between the welding torch and the welding seam of the pedal is adjusted through the bracket angle adjustment mechanism, and then the angle of the welding torch is adjusted through the welding torch angle adjustment mechanism. Finally, the welding torch is pushed by an electric telescopic rod to complete the automatic welding of the welds on both sides of the pedal, realizing the automatic welding of the entire marine ladder outfitting parts.
