DETAILED DESCRIPTION

[0018] The following is a detailed description of a ship repair welding device provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0019] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a welding device for ship repair, including a base 1, which provides support for the entire device, a plurality of self-locking universal wheels are equidistantly arranged at the bottom of the base 1, which increase the flexibility of the device when in use, a push handle is fixedly arranged on the surface of the base 1 on one side of the support plate 2, which can conveniently push the entire device to move, making the transfer of the device between different welding scenes more convenient, a support plate 2 is fixedly arranged on the surface of the base 1, a sliding plate 3 is slidably arranged on the inner wall of the support plate 2, a welding gun 4 for welding the ship welding part is installed on the surface of the sliding plate 3, and a cleaning part for cleaning the welding slag generated by the welding gun 4 during welding is installed on the surface of the sliding plate 3; the splashing of welding slag is mainly reduced by adsorbing the welding slag generated during welding at the welding part during welding.

[0020] Specifically, the cleaning part includes a pipe 5, and one end of the pipe 5 close to the welding gun 4 is trumpet-shaped. During the welding process, welding slag will splash around, and the trumpet-shaped design has obvious advantages. Its opening can increase the receiving area, so that more welding slag can be sucked into the pipe 5, thereby effectively reducing the scattering of welding slag in the surrounding environment. The pipe 5 is rotatably set on the surface of the base 1, and one end of the pipe 5 close to the sliding plate 3 is fixedly set on the surface of the sliding plate 3. The end of the pipe 5 away from the sliding plate 3 is connected to the fan 6 through a flange. Taking into account the difference in height of welding points during ship welding operations, the welding height needs to be flexibly adjusted. Therefore, an adjustment portion for adjusting the height of the sliding plate 3 is installed on one side of the support plate 2, and the adjustment portion includes a fixing rod 35, and the fixing rod 35 is fixedly arranged on the side of the sliding plate 3 away from the welding gun 4. A plurality of limiting grooves 36 are provided on the support plate 2, and a through groove 37 is provided on the outer wall of the fixing rod 35. A latch 38 is inserted into the inner wall of the through groove 37, and the latch 38 passes through the through groove 37 and is inserted into the limiting groove 36. A handle 39 is fixedly provided on the end of the fixing rod 35 away from the sliding plate 3, and the operator can make corresponding adjustments according to the height requirements of the actual welding position, thereby ensuring that the distance between the welding gun 4 and the welding point can always be maintained within an appropriate range.

[0021] When the welding position needs to be adjusted, the pin 38 is first pulled out of the through hole. During this process, the operator pulls the handle 39 by hand, and then, according to the required height of the welding position, the sliding plate 3 is driven to slide up and down by pulling the handle 39, and the height is gradually adjusted during the sliding process. When the welding position is adjusted to a suitable height, the pin 38 is passed through the barrel groove and plugged into the limit groove 36. The adjustment method is simple and easy, and can accurately adjust the welding gun 4 to a suitable height to meet the operating requirements of welding places at different heights.

[0022] like Figure 1-Figure 10 As shown, further, the welding slag generated during the welding process will not only splash everywhere, but also has a high temperature and has strong adhesion after cooling. Considering that these splashed welding slag adheres to the inner wall of the pipe 5, as time goes by, when the inner wall of the pipe 5 adsorbs too much welding slag, it is easy to cause the pipe 5 to be blocked, affecting the normal use of the pipe 5. Therefore, a knocking part is installed on the sliding plate 3. The main function of the knocking part is to knock the welding slag adsorbed in the pipe 5. In this way, the adhesion of welding slag to the inner wall of the pipe 5 can be effectively reduced, and the high-temperature welding slag splashed during welding can be reduced from adhering to the inner wall of the pipe 5, thereby ensuring the smooth and normal operation of the pipe 5.

[0023] Specifically, the knocking part includes a rotating bar 10, which is rotatably arranged on the surface of the sliding plate 3. A plurality of spring hammers 11 are provided on the side of the rotating bar 10 close to the pipe 5. A motor 12 is fixedly installed on the surface of the base 1. At the same time, a rotatable rotating rod 13 is also provided on the surface of the base 1. One end of the rotating rod 13 is fixedly connected to the output end of the motor 12. A round wheel 14 is fixed to the outer wall of the rotating rod 13. A fixed bar 15 is fixedly arranged on the side of the support plate 2 close to the motor 12. A slider 16 is slidably arranged on the fixed bar 15. A connecting rod 17 is fixed on the side of the round wheel 14 away from the motor 12. One end of the connecting rod 17 is rotatably connected to the slider 16. A pressing rod 19 is rotatably arranged on the side of the slider 16 close to the rotating bar 10 through an axle pin 18. A torsion spring is sleeved on the axle pin 18. One end of the torsion spring is fixed to the pressing rod 19. A box body 20 is fixedly installed on the surface of the sliding plate 3, and a slidable sliding sheet 21 is arranged on the inner wall of the box body 20. One side of the sliding sheet 21 is fixedly connected to the second spring 22, and one end of the second spring 22 is fixed to the inner wall of the box body 20. At the same time, a slidable push plate 23 is arranged on the surface of the sliding plate 3, and the push plate 23 is arranged in an eight-shaped shape. On the one hand, it can effectively push some obstacles in front of the welding place to ensure the smooth flow of the welding path; on the other hand, it can also form a barrier for the welding slag generated at the welding place, further reduce the situation of welding slag splashing, so as to better maintain the cleanliness of the welding working environment and reduce the adverse effects of welding slag splashing. A sliding groove 24 is opened on the side of the box body 20 close to the push plate 23, and a sliding rod 25 is fixed on the push plate 23. One end of the sliding rod 25 passes through the sliding groove 24 and is fixed to the sliding sheet 21, and the outer wall of the sliding rod 25 can slide on the inner wall of the sliding groove 24, and the side of the rotating bar 10 close to the sliding sheet 21 keeps in contact with the sliding sheet 21.

[0024] By driving the fan 6 to work and generate suction, the welding slag generated at the welding point can be adsorbed in cooperation with the pipeline 5. At the same time, the motor 12 is started and rotated, and its output end drives the rotating rod 13 to rotate. The rotation of the rotating rod 13 causes the round wheel 14 to rotate accordingly. When the round wheel 14 rotates, it drives the connecting rod 17 to rotate together. The rotation of the connecting rod 17 will push the slider 16 to slide along the fixed bar 15. During the sliding process of the slider 16, the pressing rod 19 is driven to push the rotating bar 10 to rotate downward. When the rotating bar 10 rotates downward, a plurality of spring hammers 11 arranged on one side thereof will knock on the outer wall of the pipeline 5. This knocking will cause vibration inside the pipeline 5. Due to the effect of the vibration, the welding slag attached to the inner wall of the pipeline 5 will be knocked off. Finally, the knocked-off welding slag can be sucked away and discharged by the suction generated by the fan 6. When the rotating bar 10 rotates downward, the side thereof close to the sliding sheet 21 will press against the sliding sheet 21. Due to the downward rotation of the rotating bar 10, the side of the rotating bar 10 in contact with the arc surface of the sliding sheet 21 will apply a thrust to the sliding sheet 21, causing the sliding sheet 21 to slide along the inner wall of the box body 20 in a direction away from the welding gun 4. During the sliding process, the sliding sheet 21 will squeeze the first spring 8. At the same time, the sliding of the sliding sheet 21 will drive the sliding rod 25, and the sliding rod 25 will slide together with the push plate 23 in a direction away from the welding gun 4. When the push plate 23 slides, it can automatically push the obstacles in front of the welding place, and push these obstacles away from the two sides of the welding gun 4, so as to keep the forward path unobstructed. Pushing away these obstacles can ensure that the welding work can move forward stably, making the welding process more continuous, reducing the phenomenon of frequent starting and stopping of the welding rod due to obstruction, and thus improving the welding speed. Especially in large-scale welding projects such as shipbuilding, the improvement of welding efficiency can greatly shorten the construction period and effectively reduce production costs. As the circular wheel 14 continues to rotate, the slider 16 will slide back and forth up and down with the pressure rod 19. When the slider 16 and the pressure rod 19 are out of contact with the rotating bar 10, the second spring 22 will restore its deformation and push the sliding piece 21 to slide along the inner wall of the box 20 toward the side where the welding gun 4 is located under the action of the elastic force, so that the push plate 23 returns to its initial position. At the same time, as the sliding piece 21 is reset, it will apply a thrust to the rotating bar 10, so that the rotating bar 10 also returns to its original position. When the rotating bar 10 is reset, the spring hammer 11 thereon also restores its deformation, and then the pipe 5 can be knocked again, thereby realizing the function of continuously cleaning the welding slag of the pipe 5.

[0025] like Figure 10-13 As shown, it should be noted that the lower pressure rod 19 slides back and forth up and down with the slider 16. When the slider 16 drives the lower pressure rod 19 to contact the rotating bar 10, the rotating bar 10 starts to rotate until it rotates to the top. Since the lower pressure rod 19 is connected to the torsion spring through the axle pin 18, when the lower pressure rod 19 pushes the rotating bar 10 downward and the rotating bar 10 cannot continue to rotate, the torsion spring will be under pressure. Under the action of the torsion spring, the lower pressure rod 19 will rotate upward and then move downward along the rotating bar 10. When the rotating bar 10 contacts the outer wall of the pipe 5, the lower pressure rod 19 will also rotate closely against the outer wall of the pipe 5 to avoid the rotating bar 10 and the pipe 5. When the slider 16 slides upward, the movement of the rotating bar 10 is the same.

[0026] like Figure 8-Figure 13 As shown, further, when the slag generated during welding is adsorbed by the pipe 5 and the fan 6, it takes a certain amount of time for the slag to cool down and it will not cool down immediately. Moreover, when collecting the slag, attention should be paid to the temperature of the slag to prevent it from adhering to the collection point. Therefore, a collecting part for collecting the slag sucked in by the fan 6 is installed on the surface of the base 1 on one side of the fan 6, and the heat dissipation speed of the collected slag is increased, thereby reducing the phenomenon that the slag burns the collecting part.

[0027] Specifically, the collecting part includes a fixed seat 26, which is fixed to the surface of the base 1. At the same time, a rotatable driven pulley 27 is provided on the surface of the fixed seat 26, a rotating rod 28 is fixed to the surface of the driven pulley 27, a bearing cylinder 29 is fixedly installed on the top of the rotating rod 28, a rotatable rotating disk 30 is provided on the inner wall of the fixed seat 26, and the outer wall of the bearing cylinder 29 is rotatably connected to the inner wall of the rotating disk 30, and a slidable collecting box 31 is provided on the surface of the bearing cylinder 29, and a plurality of protrusions 34 are fixedly provided on the inner wall of the collecting box 31. On the one hand, They can effectively reduce the wear of the inner wall caused by the welding slag in the collection box 31 during the contact with the inner wall, thereby extending the service life of the collection box 31; on the other hand, the protrusion 34 can prevent the welding slag from completely sticking together, which is beneficial to the subsequent processing of the welding slag. This collection box 31 is used to collect the welding slag discharged by the fan 6. The fan 6 is connected to a discharge port on the side close to the collection box 31, and the discharge port faces the collection box 31. In addition, a driving pulley 32 is fixed to the outer wall of the rotating rod 13, and the driving pulley 32 is connected to the driven pulley 27 through a cross belt 33. The surface of the supporting tube 29 is equidistantly and slidingly provided with a plurality of positioning members 40, which are limitedly connected to the supporting tube 29 by bolts. When the collecting box 31 needs to be disassembled to dump the welding slag therein, or when the collecting box 31 needs to be installed, the positioning members 40 can be slid by turning the bolts, so that the collecting box 31 can be conveniently taken out, thereby improving the convenience of the maintenance operation of the collecting box 31.

[0028] The output end of the motor 12 rotates, driving the rotating rod 13 to rotate, and then driving the round wheel 14 to rotate, so that the rotating bar 10 knocks the welding slag adsorbed on the inner wall of the pipe 5. At the same time, the rotation of the rotating rod 13 also drives the active pulley 32 to rotate, and the active pulley 32 drives the driven pulley 27 to rotate through the cross belt 33. When the driven pulley 27 rotates, it drives the rotating rod 28 to rotate. The rotation of the rotating rod 28 drives the bearing cylinder 29 to rotate, and the bearing cylinder 29 shakes and rotates along the inner wall of the rotating disk 30. This rotation drives the collecting box 31 to rotate together, and the rotation of the collecting box 31 causes the welding slag to shake in it; This shaking can, on the one hand, reduce the adhesion of welding slag in the collection box 31, and on the other hand, increase the cooling rate of the welding slag. If the welding slag accumulates in a local location for a long time, especially under high temperature conditions, it will cause excessive thermal stress and corrosion to the local collection box 31. Shaking the collection box 31 can make the welding slag evenly distributed, effectively avoiding the problems of local overheating and aggravated chemical corrosion, thereby extending the service life of the collection box 31.

[0029] Furthermore, considering the need to adjust the height of the welding gun 4 according to the position of the welding point, a first hollow tube 7 is fixedly installed on the surface of the base 1, a first spring 8 is fixed to the inner wall of the first hollow tube 7, and a slidable second hollow tube 9 is also provided on the inner wall thereof, one end of the first spring 8 is fixed to the bottom of the second hollow tube 9, and the fan 6 is fixed on the surface of the second hollow tube 9.

[0030] When the sliding plate 3 is slid upward or downward to adjust the height, such as when adjusting upward, pulling the handle 39 will make the sliding plate 3 slide upward along the inner wall of the support plate 2, which will drive the air duct on the sliding plate 3 to rotate. At this time, the air duct is tilted upward. This upward tilted state is conducive to the faster discharge of the adsorbed welding slag, thereby improving the circulation speed of the welding slag. Moreover, when the pipeline 5 is tilted upward, the second hollow tube 9 at the bottom of the fan 6 will press the spring downward and slide downward along the inner wall of the first hollow tube 7, so that the first spring 8 is compressed. In this way, the fan 6 can slide downward slightly, thereby ensuring that the fan 6 will not affect the discharge process of the welding slag into the collection box 31 when discharging the welding slag; When the sliding plate 3 is adjusted downward, it can be pushed to slide downward. During this process, the sliding plate 3 will drive the pipe 5 to rotate downward. As the pipe 5 rotates downward, the center of the sliding plate 3 will face the welding position. At this time, the second hollow tube 9 will slide upward along the first hollow tube 7, so that the spring is in a stretched state. Through such a design, whether the welding height is adjusted upward or downward, it will not affect the collection of welding slag.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
