Description

Technical Field

[0001] This utility model relates to the field of submerged arc welding machine technology, and in particular to a submerged arc welding machine moving device. Background Technology

[0002] Submerged arc welding (SAW) machines are welding machines that use an electric arc burning under a layer of flux to perform welding. Their inherent advantages, such as stable welding quality, high welding productivity, and minimal arc light and fumes, make them a primary welding machine in the fabrication of pressure vessels, pipe sections, and box-girder steel structures. Existing SAW machines typically move along a track surface, with a motor driving rotating wheels. This rotation of the wheels allows the welding head to move and weld over the workpiece.

[0003] However, submerged arc welding machines move by rotating wheels and generating friction with the track surface. The wheels are prone to slipping on the track surface. When the wheels slip, the friction between them and the track decreases, making it difficult for the wheels to move the submerged arc welding machine. When the wheels move on a relatively inclined track surface, they are prone to insufficient power, making it difficult for the submerged arc welding machine to adapt to different terrains, thus causing inconvenience in the use of the device.

[0004] Therefore, it is necessary to propose a moving device for submerged arc welding machines to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a submerged arc welding machine moving device to solve the problem mentioned in the background art that the submerged arc welding machine moves by friction between the rotating moving wheel and the track surface, the moving wheel is prone to slipping on the track surface, the friction between the moving wheel and the track will decrease when the moving wheel slips, and the moving wheel will be difficult to drive the submerged arc welding machine to move.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a submerged arc welding machine moving device, comprising a moving track, a connecting block fixedly connected to the side of the moving track, and a support plate fixedly connected to the top of the connecting block;

[0007] The side of the support plate is provided with a movable component;

[0008] The moving component includes a lead screw, a servo motor, a base, and a limit rod;

[0009] The lead screw is rotatably connected to the outside of the support plate and one end of the lead screw is fixedly connected to one end of the servo motor output shaft. The outside of the lead screw is threadedly connected to the inside of the base. The inside of the base has a threaded hole that mates with the lead screw, and the inside of the base is slidably connected to the outside of the limiting rod.

[0010] Preferably, the servo motor is fixedly connected to the outside of the support plate.

[0011] Preferably, the end of the limiting rod is fixedly connected to the outside of the support plate, and the limiting rod and the lead screw are parallel to each other.

[0012] Preferably, the moving track has a groove inside, and a slider is fixedly connected to the outside of the base, with the slider and the groove being slidably connected.

[0013] Preferably, a dust collection component is provided on the side of the slider, the dust collection component including an electric push rod, a mounting plate, a connecting sleeve and a connecting tube;

[0014] The electric push rod is fixedly connected to the outside of the slider and the inside of the slider. The telescopic end of the electric push rod is fixedly connected to one side of the mounting plate, the other side of the mounting plate is fixedly connected to the outside of the connecting sleeve, and the top of the connecting sleeve is fixedly connected to the bottom of the connecting tube.

[0017] Preferably, a welding assembly connecting rod is fixedly installed on the top of the base.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. By setting up a moving component, when the welding head of the submerged arc welding machine needs to move to weld the workpiece, the servo motor can be turned on. The servo motor will drive the lead screw to rotate, and the lead screw will drive the base to move horizontally. The base will drive the welding head of the submerged arc welding machine to move horizontally through the welding component connecting rod. Since the lead screw is externally connected to the internal thread of the base, the welding head of the submerged arc welding machine can move smoothly, avoiding the problem of slippage and difficulty in moving and welding, thus bringing convenience to the use of the device.

[0020] 2. By setting up a dust collection component, when the welding head of the submerged arc welding machine welds the workpiece, although flux will cover the surface of the weld to reduce the dispersion of fumes, a small amount of fumes will still be dispersed in the air, causing environmental pollution. At this time, the vortex air pump connected to the connecting pipe can be used to absorb and collect these small amounts of fumes through the suction hole. At the same time, the design of the slider and the slide groove can further improve the stability of the base movement, thereby improving the practicality of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This utility model provides, for example Figures 1-3 The submerged arc welding machine moving device shown includes a moving track 1, a connecting block 2 fixedly connected to the side of the moving track 1, a support plate 3 fixedly connected to the top of the connecting block 2, and a moving component provided on the side of the support plate 3. The moving component includes a lead screw 4, a servo motor 5, a base 6 and a limit rod 8. The moving component can be used to facilitate the stable movement of the welding head of the submerged arc welding machine.

[0027] The lead screw 4 is externally rotatably connected to the inside of the support plate 3, and one end of the lead screw 4 is fixedly connected to one end of the output shaft of the servo motor 5. The lead screw 4 is externally threadedly connected to the inside of the base 6. The inside of the base 6 has a threaded hole that mates with the lead screw 4, and the inside of the base 6 is slidably connected to the outside of the limiting rod 8. The outside of the servo motor 5 is fixedly connected to the outside of the support plate 3, and the end of the limiting rod 8 is fixedly connected to the outside of the support plate 3. The limiting rod 8 and the lead screw 4 are parallel to each other. A welding assembly connecting rod 7 is fixedly installed on the top of the base 6. When the welding head of the submerged arc welding machine needs to move to weld the workpiece, the servo motor 5 can be turned on. The servo motor 5 will drive the lead screw 4 to rotate, and the lead screw 4 will drive the base 6 to move horizontally. The base 6 will drive the welding head of the submerged arc welding machine to move horizontally through the welding assembly connecting rod 7. Because the outside of the lead screw 4 is threadedly connected to the inside of the base 6, the welding head of the submerged arc welding machine can move smoothly, avoiding the problem of slippage and difficulty in moving and welding, thus bringing convenience to the use of the device.

[0028] In addition, the moving track 1 has a groove 9 inside, and the base 6 is fixedly connected to the outside of the slider 10. The slider 10 is slidably connected to the groove 9. The side of the slider 10 is provided with a dust collection component, which includes an electric push rod 11, a mounting plate 12, a connecting sleeve 13 and a connecting tube 14. The outside of the electric push rod 11 is fixedly connected to the inside of the slider 10, and the telescopic end of the electric push rod 11 is fixedly connected to one side of the mounting plate 12. The other side of the mounting plate 12 is fixedly connected to the outside of the connecting sleeve 13. The top of the connecting sleeve 13 is fixedly connected to the bottom of the connecting tube 14. The inside of the connecting sleeve 13 is provided with a suction hole 15, and the inside of the connecting sleeve 13 is hollow. The connecting sleeve 13 is connected to the connecting tube 14. When the welding head of the submerged arc welding machine welds the workpiece, although flux covers the surface of the weld to reduce the dispersion of fumes, a small amount of fumes will still be dispersed in the air, causing environmental pollution. At this time, the vortex air pump connected to the connecting pipe 14 can be used to absorb and collect these small amounts of fumes through the suction hole 15. Then, a purification component is set at one end of the exhaust pipe of the vortex air pump to purify and discharge these fumes. The electric push rod 11 can adjust the position of the connecting sleeve 13 through the mounting plate 12 to facilitate the absorption of fumes by the connecting sleeve 13. At the same time, the design of the slider 10 and the groove 9 can further improve the stability of the base 6 movement, thereby improving the practicality of the device.

[0029] Finally, a fixing plate 16 is fixedly connected to the outside of the moving track 1, and a fixing hole 17 is provided inside the fixing plate 16. When it is necessary to fix the moving track 1, a fixing bolt can be inserted into the fixing hole 17 to fix the moving track 1.

[0030] Working Principle: When the welding head of the submerged arc welding machine needs to move to weld the workpiece, the servo motor 5 can be turned on. The servo motor 5 will drive the lead screw 4 to rotate, which in turn will drive the base 6 to move horizontally. The base 6 will then drive the welding head of the submerged arc welding machine to move horizontally via the welding assembly connecting rod 7. Because the lead screw 4 is externally connected to the internal thread of the base 6, the welding head of the submerged arc welding machine can move smoothly, avoiding slippage and difficulty in welding. This brings convenience to the use of the device. When the welding head of the submerged arc welding machine is welding the workpiece, although there will be flux covering it... While reducing the dispersion of fumes on the weld surface, a small amount of fumes will still remain in the air, causing environmental pollution. In this case, a vortex air pump connected to the connecting pipe 14 can be used to collect these small amounts of fumes through the suction hole 15. A purification component is then installed at one end of the exhaust pipe of the vortex air pump to purify and discharge these fumes. The electric push rod 11 can adjust the position of the connecting sleeve 13 through the mounting plate 12 to facilitate the adsorption of fumes by the connecting sleeve 13. At the same time, the design of the slider 10 and the groove 9 can further improve the stability of the base 6 movement, thereby improving the practicality of the device.
