[0017] A push handle is fixedly arranged on one side of the surface of the base where the support plate is located.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, by arranging the cleaning part, welding can be carried out while moving the whole device, and the welding slag generated at the welding part can be adsorbed while welding to prevent the splashing of welding slag;

[0020] By arranging the knocking part, through the coordinated work of components such as a motor, a rotating rod, a round wheel, a connecting rod, a slider, a pressing rod, a torsion spring, a rotating bar and a spring hammer, the pipeline can be knocked, so that the welding slag in the pipeline is knocked down due to vibration and is sucked away by a blower, realizing the cleaning of the adsorbed welding slag on the inner wall of the pipeline, ensuring the smoothness of the pipeline, effectively reducing the adhesion of welding slag on the inner wall of the pipeline, and reducing the adhesion of high-temperature welding slag splashing during welding on the inner wall of the pipeline, ensuring the smoothness and normal operation of the pipeline;

[0021] Moreover, while the rotating bar drives the spring hammer to knock the pipeline, the rotating bar can also drive the push plate to automatically push the obstacles in front of the welding part, push these obstacles away from both sides of the welding torch, so as to keep the forward path unobstructed. Pushing away these obstacles can ensure that the welding work can proceed stably, make the welding process more continuous, reduce the phenomenon that the welding rod starts and stops frequently due to being blocked, and thus improve 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 the production cost;

[0022] By arranging the collection part, the collected welding slag with a relatively high temperature is shaken. This shaking can, on the one hand, reduce the adhesion of welding slag in the collection box, and on the other hand, increase the cooling speed of the welding slag. Because if the welding slag accumulates in a local position for a long time, especially in a high-temperature state, it will cause excessive thermal stress and corrosion to the local part of the collection box. Shaking the collection box can make the welding slag evenly distributed, effectively avoiding the problems of local overheating and aggravated chemical corrosion, thereby prolonging the service life of the collection box;

[0038] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device, and environment. According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments, and the adjustments or modifications still fall within the scope of the appended claims. Detailed implementation manners

[0039] The following describes in detail a welding device for ship repair provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0040] As Figures 1-5 shown, an embodiment of the present invention provides a welding device for ship repair, including a base 1 that provides support for the entire device. A plurality of self-locking universal wheels are equidistantly arranged at the bottom of the base 1 to increase the flexibility of the device during 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 scenarios more convenient. A support plate 2 is fixedly arranged on the surface of the base 1. A sliding plate 3 is slidably arranged inside the support plate 2. A welding torch 4 for welding the welding part of the ship is installed on the surface of the sliding plate 3. A cleaning part for cleaning the welding slag generated during the welding of the welding torch 4 is installed on the surface of the sliding plate 3; mainly by adsorbing the welding slag generated during the welding of the welding part during the welding process to reduce the splashing of the welding slag.

[0041] Specifically, the cleaning part includes a pipeline 5. One end of the pipeline 5 close to the welding torch 4 is in a horn shape. During the welding process, welding slag will splash in all directions, and the horn-shaped design has obvious advantages. Its opening can increase the receiving area, enabling more welding slag to be sucked into the pipeline 5, thereby effectively reducing the scattering of welding slag in the surrounding environment. The pipeline 5 is rotatably arranged on the surface of the base 1. One end of the pipeline 5 close to the sliding plate 3 is fixedly arranged on the surface of the sliding plate 3. The end of the pipeline 5 far from the sliding plate 3 is connected with a blower 6 through a flange plate;

[0042] Considering the situation that in ship welding operations, there are differences in the heights of the welding points and the need to flexibly adjust the welding height, an adjusting part for adjusting the height of the sliding plate 3 is installed on one side of the support plate 2. The adjusting part includes a fixing rod 35. The fixing rod 35 is fixedly arranged on the side of the sliding plate 3 far from the welding torch 4. A number of limiting grooves 36 are provided on the support plate 2. A through groove 37 is provided on the outer side wall of the fixing rod 35. A plug pin 38 is inserted into the inner wall of the through groove 37. The plug pin 38 passes through the through groove 37 and is inserted into the limiting groove 36. A handle 39 is fixedly arranged at the end of the fixing rod 35 far from the sliding plate 3. The operator can make corresponding adjustments according to the height requirements of the actual welding position, so as to ensure that the distance between the welding torch 4 and the welding point can always be maintained within a suitable range.

[0043] When the welding position needs to be adjusted, first pull out the plug pin 38 from the through hole. During this process, the operator pulls the handle 39 by hand. Subsequently, according to the height required by the welding position, drive the sliding plate 3 to slide up and down by pulling the handle 39, and gradually complete the height adjustment during the sliding process. When the welding position is adjusted to the appropriate height, insert the plug pin 38 through the barrel groove and insert it into the limiting groove 36. The adjustment method is simple and easy to operate, and can accurately adjust the welding torch 4 to the appropriate height to meet the operation requirements of welding points at different heights.

[0044] As Figures 1-10 shown, further, the welding slag generated during the welding process not only splashes everywhere, but also has a high temperature and strong adhesiveness after cooling. Considering that these splashed welding slags adhere to the inner wall of the pipeline 5, over time, when too much welding slag is adsorbed on the inner wall of the pipeline 5, it is easy to cause the pipeline 5 to be blocked, affecting the normal use of the pipeline 5. Therefore, a knocking part is installed on the sliding plate 3. The main function of this knocking part is to knock the welding slag adsorbed in the pipeline 5, effectively reducing the adhesion of the welding slag on the inner wall of the pipeline 5, reducing the adhesion of the high-temperature welding slag splashed during welding on the inner wall of the pipeline 5, and ensuring the smoothness and normal operation of the pipeline 5.

[0045] Specifically, the knocking part includes a rotating bar 10 which is rotatably arranged on the surface of the sliding plate 3. A number of spring hammers 11 are provided on the side of the rotating bar 10 close to the pipeline 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 on the outer side 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 a pin 18. A torsion spring is sleeved on the pin 18, and one end of the torsion spring is fixed to the pressing rod 19;

[0046] A box body 20 is fixedly installed on the surface of the sliding plate 3. A slidable sliding piece 21 is arranged on the inner wall of the box body 20. One side of the sliding piece 21 is fixedly connected to a 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 provided on the surface of the sliding plate 3. The push plate 23 is arranged in an eight-shaped manner. On the one hand, it can effectively push some obstacles existing in front of the welding part to ensure the smoothness of the welding path; on the other hand, it can also block the welding slag generated at the welding part, further reducing the situation of welding slag splashing, so as to better maintain the cleanliness of the welding working environment and reduce the adverse effects brought by welding slag splashing. A chute 24 is opened on the side of the box body 20 close to the push plate 23. A sliding rod 25 is fixed on the push plate 23. One end of the sliding rod 25 passes through the chute 24 and is fixed to the sliding piece 21, and the outer side wall of the sliding rod 25 can slide on the inner wall of the chute 24. The side of the rotating bar 10 close to the sliding piece 21 is in contact with the sliding piece 21.

[0047] By driving the blower 6 to work and generate suction, and cooperating with the pipeline 5, the welding slag generated at the welding part can be adsorbed. 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 prompts 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, it drives the pressing rod 19 to push the rotating bar 10 to rotate downward. When the rotating bar 10 rotates downward, a number of spring hammers 11 arranged on one side of it will knock on the outer side wall of the pipeline 5. This knocking will cause vibrations inside the pipeline 5. Due to the effect of the vibrations, the welding slag attached to the inner wall of the pipeline 5 will be knocked off, and finally these knocked-off welding slags can be sucked away and discharged by the suction generated by the blower 6;

[0048] 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.

[0049] 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.

[0050] like Figures 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.

[0051] like Figures 8-13As shown, further, when using the pipeline 5 and the fan 6 to cooperate in adsorbing the welding slag generated during the welding process, the welding slag needs a certain time to cool down and will not cool down immediately. Moreover, when collecting the welding slag, attention needs to be paid to the temperature of the welding slag to prevent it from adhering to the collection area. Therefore, a collection part for collecting the welding slag inhaled by the fan 6 is installed on the surface of the base 1 on the side of the fan 6, so as to increase the heat dissipation speed of the collected welding slag, thereby reducing the phenomenon that the welding slag burns out the collection part.

[0052] Specifically, the collection part includes a fixed seat 26, and the fixed seat 26 is fixed on 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 on the surface of the driven pulley 27, and a bearing cylinder 29 is fixedly installed at the top of the rotating rod 28. A rotatable rotating disk 30 is arranged on the inner wall of the fixed seat 26. The outer side wall of the bearing cylinder 29 is rotatably connected to the inner wall of the rotating disk 30. A slidable collection box 31 is provided on the surface of the bearing cylinder 29. A plurality of protrusions 34 are fixedly arranged on the inner wall of the collection box 31. On the one hand, they can effectively reduce the wear of the inner wall of the collection box 31 caused by the welding slag in contact with the inner wall during the contact process, and extend the service life of the collection box 31; on the other hand, the protrusions 34 can prevent the welding slag from completely adhering together, which is beneficial to the subsequent treatment operation of the welding slag. This collection box 31 is used to collect the welding slag discharged by the fan 6. One side of the fan 6 close to the collection box 31 is connected with a discharge port, and the discharge port faces the collection box 31. In addition, a driving pulley 32 is fixed on the outer side wall of the rotating rod 13, and the driving pulley 32 is drivingly connected with the driven pulley 27 through a crossed belt 33;

[0053] A plurality of positioning members 40 are equidistantly and slidably arranged on the surface of the bearing cylinder 29. These positioning members 40 are connected to the bearing cylinder 29 through bolts for limit connection. When it is necessary to disassemble the collection box 31 to pour the welding slag therein or perform the installation operation of the collection box 31, the positioning member 40 can be slid by rotating the bolt, so as to conveniently take the collection box 31, improving the convenience of the maintenance operation of the collection box 31.

[0054] By the rotation of the output end of the motor 12, the rotating rod 13 is driven to rotate, and then the round wheel 14 is driven to rotate, so that the rotating bar 10 knocks the welding slag adsorbed on the inner wall of the pipeline 5. At the same time, the rotation of the rotating rod 13 will also drive the driving pulley 32 to rotate. The driving pulley 32 drives the driven pulley 27 to rotate through the crossed belt 33. When the driven pulley 27 rotates, it drives the rotating rod 28 to rotate. The rotation of the rotating rod 28 further causes the bearing cylinder 29 to rotate. The bearing cylinder 29 rotates and shakes along the inner wall of the rotating disk 30. This rotation will drive the collection box 31 to rotate together, and the rotation of the collection box 31 makes the welding slag shake therein;

[0055] This kind of 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 speed of the welding slag. Because if the welding slag accumulates in a local position for a long time, especially in a high-temperature state, it will cause excessive thermal stress and corrosion to the local part of the 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 prolonging the service life of the collection box 31.

[0056] Furthermore, considering the situation that the height of the welding gun 4 needs to be adjusted according to the position of the welding joint, 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 its inner wall. One end of the first spring 8 is fixed to the bottom of the second hollow tube 9, and the blower 6 is fixed to the surface of the second hollow tube 9.

[0057] When the sliding plate 3 is slid up or down to adjust the height, for example, when adjusting upward, pulling the handle 39 will cause the sliding plate 3 to 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 in an upward inclined state. This upward inclined state is conducive to the faster discharge of the adsorbed welding slag, thereby improving the flow rate of the welding slag. Moreover, when the pipeline 5 is upward inclined, the second hollow tube 9 at the bottom of the blower 6 will press down the spring and slide downward along the inner wall of the first hollow tube 7, causing the first spring 8 to be compressed. In this way, the blower 6 can slide downward slightly, thereby ensuring that the blower 6 will not affect the discharge process of the welding slag into the collection box 31 when discharging the welding slag;

[0058] When the sliding plate 3 is adjusted downward, the sliding plate 3 can be pushed downward. During this process, the sliding plate 3 will drive the pipeline 5 to rotate downward. As the pipeline 5 rotates downward, the center of the sliding plate 3 will face the welding joint. At this time, the second hollow tube 9 will slide upward along the first hollow tube 7, making the spring in a stretched state. Through such a design, whether the welding height is adjusted upward or downward, it will not affect the collection of the welding slag.

[0059] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
