[0025] The embodiments of the present disclosure aim to solve the problem of inconvenient operation during aerial welding of erected steel structures in existing high-rise buildings. In view of this, the embodiments of the present disclosure propose a submerged arc welding arc welding device for steel structures, as Figure 1 shown, including a welding torch and a snap ring structure;

[0026] As Figure 4 and 5As shown in the figure, the snap ring structure 1 includes an outer ring 11, a vertical wall 12, intermediate teeth 13 and an intermediate ring 14. The outer ring 11 is installed on one side of the surface of the vertical wall 12, and an annular groove 121 coaxial with the outer ring 11 is formed in the vertical wall 12. An intermediate ring 14 is rotatably installed in the annular groove 121, and installation grooves 122 are symmetrically formed in the annular groove 121 along the intermediate ring 14. Ball bearings 15 for cooperating with the rotation of the intermediate ring 14 are arranged in the installation grooves 122. The outer ring 11 and the intermediate ring 14 are coaxial and arranged at intervals. Tooth teeth are fixedly arranged on the opposite surfaces of the outer ring 11 and the intermediate ring 14. An intermediate tooth 13 is rotatably engaged in the annular groove 121. A welding torch 2 mounting bracket 16 is fixedly installed on the surface of the intermediate tooth 13. A welding torch 2 is fixedly installed at the end of the welding torch 2 mounting bracket 16. The welding torch 2 mounting bracket 16 is made of PVC soft glue material. It should be noted that in the embodiment of the present disclosure, the welding torch 2 mounting bracket 16 is made of PVC soft glue material, so that it can be bent arbitrarily in a manner similar to a mobile phone holder. Moreover, in the embodiment of the present disclosure, the mounting bracket 16 can also be made of other materials that can be bent arbitrarily.

[0027] By rotating the intermediate ring 14, the intermediate teeth 13 can be driven to revolve around the intermediate ring 14, so that the welding torch 2 can revolve to change its position, and further the welding torch 2 can automatically perform circular movement welding. Thus, while improving the welding accuracy, it can avoid dangerous accidents during the aerial operation of the operator.

[0028] It should be noted that in the embodiment of the present disclosure, four lifting lugs 19 are uniformly arranged around the snap ring structure 1, so that it can be lifted through the lifting lugs 19, and further drive the snap ring structure 1 to perform up and down lifting welding.

[0029] As Figure 1 shown, it should be noted that during the use of the embodiment of the present disclosure, a guard plate 18 is installed between the outer ring 11 and the mounting ring 17. The guard plate 18 is located on the surfaces of the outer ring 11 and the mounting ring 17 away from the vertical arm side. An annular sliding groove 181 for accommodating the circular movement of the welding torch 2 is formed on the surface of the guard plate 18, so that the safety during operation can be improved through the enclosure of the guard plate 18.

[0030] As Figure 3 and 5 shown, the intermediate ring 14 axially slightly passes through the vertical wall 12. The end of the intermediate ring 14 passing through the vertical wall 12 forms a transmission part 131. A transmission gear 132 is arranged on the outer surface of the transmission part 131. A side wall groove 135 is formed on the side of the vertical wall 12 away from the outer ring 11. A motor 133 is fixedly installed in the side wall groove 135. The motor 133 is meshed with the transmission gear 132 through a driving gear 134, so as to drive the transmission part 131 to rotate, and further drive the intermediate ring 14 to rotate.

[0031] By starting the motor 133, the driving gear 134 and the transmission gear 132 that mesh with each other drive the intermediate ring 14 to rotate, and then drive the intermediate teeth 13 and the welding torch 2 to rotate while the intermediate ring 14 rotates. Furthermore, the entire welding torch 2 can be driven to perform circular movement and welding, thereby improving the welding precision and avoiding dangerous accidents during the aerial operation of the operator.

[0032] As Figures 3 to 5 shown, an installation ring 17 is fixedly installed at the axis center of the vertical wall 12. The installation ring 17 is coaxial with the intermediate ring 14 and is spaced apart. The lengths of both ends of the installation ring 17 are greater than those of the intermediate ring 14, and a steel structure is fixed inside the installation ring 17.

[0033] Since the lengths of both ends of the installation ring 17 are greater than those of the intermediate ring 14, it not only increases the area for fixing the steel structure for convenient hoisting, but also can avoid being affected by the transmission part 131 when installing the steel structure.

[0034] The working process of the embodiment of the present disclosure:

[0035] When preparing for welding, first use a crane to lower the snap ring structure 1 from the top of the erected steel structure to a position close to the ground, and then the operator bends the mounting frame 16 so that the welding torch 2 can be close to the steel structure for subsequent welding; after the operator bends the mounting frame 16 to adjust the welding position of the welding torch 2, start the crane to drive the snap ring structure 1 to move upward.

[0036] After the snap ring structure 1 moves upward and stops moving, then start the motor 133, so that the driving gear 134 and the transmission gear 132 that mesh with each other drive the transmission end and the intermediate ring 14 to rotate. While the intermediate ring 14 rotates, the intermediate teeth 13 and the welding torch 2 can be driven to rotate, so that the welding torch 2 can be driven to perform circular movement and weld the steel structure at the axis center. Furthermore, the welding precision can be improved while avoiding dangerous accidents during the aerial operation of the operator.

[0037] After completing the circular welding, restart the crane to drive the snap ring structure 1 to move upward again, so as to repeat starting the motor 133 to drive the welding torch 2 to perform circular rotation for welding again.

[0038] Alternatively, during the process of starting the crane to drive the snap ring structure 1 to move upward, the crane drives the snap ring structure 1 to continuously move upward, and while the crane drives the snap ring structure 1 to move, the motor 133 is started. Thus, during the process of the snap ring structure 1 moving upward, the motor 133 can drive the transmission end and the intermediate ring 14 to rotate through the meshing driving gear 134 and transmission gear 132, so as to drive the intermediate teeth 13 and the welding torch 2 to rotate through the rotation of the intermediate ring 14. Furthermore, during the process of the snap ring structure 1 continuously moving upward, the welding torch 2 can be driven to perform circular movement welding, and then welding of a spiral track can be carried out.

[0039] After the welding work is completed, the snap ring structure 1 is just located at the top of the erected steel structure, so that the snap ring structure 1 can be taken out from the top of the steel structure after the welding is completed. Thus, the welding work on the erected steel structure is completed.
