TECHNICAL FIELD
[0001] The application belongs to the technical field of lamp pole welding, and particularly relates to a lamp pole curved surface welding device and a welding method thereof. BACKGROUND
[0002] Most of the roadside street lamps commonly use steel conical lamp poles. The lamp pole adopts a conical design, and the mechanical properties are optimized through a shape of a larger bottom diameter and a gradually tapered top, so that the material usage is reduced while the strength is ensured. The general manufacturing process is as follows: first, the coiled steel plate is unfolded by an uncoiler, and the flatness of the steel plate is corrected by a leveler to avoid edge or misalignment during subsequent coiling. Then, the surface of the steel plate is preliminarily derusted to remove the oxide scale and loose rust, laying a foundation for subsequent welding and corrosion prevention. Then, according to the lamp pole design drawing, the steel plate is cut into a fan-shaped blank through numerical control equipment. The arc length difference of the conical lamp pole fan-shaped blank needs to match the design taper. After coiling and beveling, the welding step can be entered.
[0003] Before welding, the oil stains, rust and oxide scale within 20 mm on both sides of the bevel are cleaned by using a steel wire brush and acetone to expose the metal luster. Then, the curved surface blank is fixed, and appropriate welding wire and flux are selected. The surface oxide layer of the welding wire wiped by alcohol is removed. Finally, the lamp pole curved surface can be welded by the submerged arc welding equipment. The lamp pole welded by the submerged arc welding has stable weld quality and excellent mechanical properties.
[0004] After the submerged arc welding work, the welding step is not yet completed, and there is a crucial step: finishing. After the submerged arc welding work, the excess flux is still left at the weld position. The staff often recovers the flux by using a recovery trolley. However, after recovering the flux, there is a key step that needs to be completed manually by the staff, which is slag cleaning. The staff needs to manually knock off the slag embedded in the root of the weld. After the welding is completed, the slag still has a certain temperature. Therefore, the staff needs to wait for a period of time until the slag cools to an appropriate temperature before manually cleaning. Therefore, the cleaning efficiency is low. SUMMARY
[0005] The technical problem to be solved by the application is to overcome the shortcomings of the prior art and provide a lamp pole curved surface welding device and a welding method thereof.
[0006] The technical scheme adopted to solve the above technical problem is: A lamp pole curved surface welding device, comprising a submerged arc welding trolley, a submerged arc welding gun, a lamp pole body, a placing rack and a slag cleaning trolley, the submerged arc welding gun is fixedly arranged at the top of the submerged arc welding trolley, the slag cleaning trolley is fixedly arranged at the tail of the submerged arc welding trolley, the lamp pole body is arranged on the placing rack, a longitudinal seam is formed in the lamp pole body, and the submerged arc welding gun is opposite to the longitudinal seam.

[0015] Through the above technical scheme, the spade head will first contact the molten slag, and then cut off the molten slag hooked by the hook rod, the cut-off molten slag will fall into the guide plate, and the thickness of the spade head is greater than that of the guide plate, so that a height difference is generated between the spade head and the guide plate, and it is difficult for the molten slag cut off by the spade head to go out from the guide plate through the spade head position after entering the guide plate, and then finally enters the storage box through the connecting hose, thereby facilitating the collection of the cleaned molten slag.
[0016] Further, the height of the connecting portion between the storage box and the connecting hose is greater than the height of the other end of the storage box, and the height of the connecting portion between the guide plate and the connecting hose is greater than the height of the connecting portion between the guide plate and the spade head.
[0017] Through the above technical scheme, the backwardly inclined storage box can ensure that the molten slag collected therein will not slide out of the guide plate along the connecting hose, thereby ensuring the storage effect of the molten slag, and facilitating the continuous storage work of the molten slag.
[0018] Further, the storage mechanism comprises a bottom gear, a bottom rotating rod, a bottom wheel, a side short rod, a fixed rod and a sliding rod, the bottom rotating rod penetrates through the side wall of the collecting plate, one end of the bottom rotating rod is fixedly connected with the side wall of the bottom gear, the other end is fixedly connected with the middle position of the bottom wheel, the bottom gear is engaged with the top gear, the side short rod is fixedly connected with the side wall of the bottom wheel, the other end of the side short rod is rotatably connected with the side wall of the guide plate near the spade head, a movement groove is formed in the side wall of the collecting plate, the sliding rod is slidably connected with the inner wall of the movement groove, the other end of the sliding rod is fixedly connected with the side wall of the guide plate near the connecting hose, the fixed rod is fixedly arranged on the side wall of the collecting plate, and the other end of the fixed rod is fixedly connected with the side wall of the storage box.

[0020] Further, the movement groove is quadrilateral, and the four sides of the movement groove are all arranged obliquely.
[0021] Through the technical scheme, the four obliquely arranged sides enable the sliding rod to slide obliquely in the movement groove, and the side short rod also pulls the other end of the guide plate, so that the guide plate presents an oblique movement state due to the different pulling directions of the two ends of the guide plate, and then the molten slag is cut off and poured into the storage box.
[0022] Further, the two slag rapping plate side walls are fixedly provided with rotating seats, the rotating seats are rotatably connected with bottom rods, the other ends of the bottom rods are rotatably connected with top rods, an intermediate sleeve is rotatably connected between the two top rods, a fixed plate is fixedly connected to the side wall of the intermediate sleeve, the other end of the fixed plate is fixedly connected to the side wall of the hook rod, a connecting movable sleeve is sleeved at the position where the bottom rod and the top rod are rotatably connected, and a double-end push rod is arranged between the two connecting movable sleeves.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

The lamp post body 3 is mounted on the placement frame 4, and a longitudinal seam 6 is formed on the lamp post body 3. The submerged arc welding torch 2 is directly facing the longitudinal seam 6, and the submerged arc welding torch 2 will weld the longitudinal seam 6 under the traction of the submerged arc welding carriage 1. Figure 1 - Figure 3 As can be seen from this, the submerged arc welding trolley 1 is also equipped with a flux recovery function, which can then recover the loose, unmelted flux after welding.
[0030] A fixed frame 7 is fixedly installed on the top of the slag cleaning trolley 5. A crossbeam 8 is installed on the fixed frame 7. A vertical plate 9 is fixedly installed on one end of the crossbeam 8 facing the longitudinal seam 6. A counterweight 10 is fixedly installed on the other end of the crossbeam 8. A connecting plate 11 is fixedly connected to the other end of the vertical plate 9. A striking plate 12 and a collecting plate 13 are fixedly installed on both ends of the connecting plate 11, respectively. The counterweight 10 can balance the weight at both ends of the crossbeam 8 to ensure the stability of the crossbeam 8 and the slag cleaning trolley 5.
[0031] The side wall of the striking plate 12 is provided with a hook rod 14. The hook rod 14 is L-shaped, and the short side of the hook rod 14 is facing the longitudinal seam 6.

The end of the hook rod 14 that is in direct contact with the slag can be rounded or a sharper point, as long as it can hook up the slag. The end of the hook rod 14 that hooks up the slag is the short side. Because the depth of the longitudinal seam 6 is limited, if you want to hook up the slag on the longitudinal seam 6, the length of the hook rod 14 used to hook up the slag cannot be too long, so this end needs to be the short side.
