[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Please refer to Figures 1 to 4 , and now a pipe pile welding device provided by the present utility model will be described. The pipe pile welding device includes a support assembly 1, a welding robot 2 and a control panel 3. The pipe pile located above and the pipe pile located below among the two pipe piles to be welded are respectively defined as an upper pipe pile 4 and a lower pipe pile 5. The pipe piles to be welded are arranged vertically, and the upper pipe pile 4 and the lower pipe pile 5 are in contact with each other. The support assembly 1 is disposed around the outer wall of the lower pipe pile 5 near the upper end, and the height of the support assembly 1 can be adjusted; the welding robot 2 is connected to the upper end of the support assembly 1 and is used for welding the ends of two adjacent pipe piles. The welding robot 2 has a degree of freedom to move around the outer circumference of the pipe pile on the support assembly 1; the control panel 3 is electrically connected to the welding robot 2 and has a control module for controlling the operation of the welding robot 2.

[0031] Compared with the prior art, the pipe pile welding device provided by the present utility model sets the support assembly 1 on the lower pipe pile 5, connects the welding robot 2 to the support assembly 1, enables the welding robot 2 to move along the circumference of the pipe pile, and then can weld the pipe pile to achieve the purpose of full welding. By operating the control panel 3 by the staff, the operation of the welding robot 2 can be controlled. When the welding robot 2 is inconvenient to operate, manual welding and other operations can be coordinated, solving the technical problems of high manual labor intensity and low welding efficiency during pipe pile welding operations, and having the technical effects of saving manual labor, improving the automation level of pipe pile welding, and improving welding efficiency.

[0032] The welding robot 2 used in this embodiment is a pipeline welding robot used in the prior art, which can realize operations such as automatic welding of pipelines. Connecting it to the support assembly 1 is equivalent to providing a support for the welding robot 2, facilitating the welding operation of the welding robot 2. The operation of the welding robot 2 is controllable, and the operation of the welding robot 2 can be controlled by the set control panel 3, thereby realizing the automatic welding of two pipe piles. The control panel 3 can adopt electronic devices in the prior art. After being connected to the welding robot 2, it can control the operation of the welding robot 2, thereby realizing the welding operation of the pipe pile.

[0033] In some embodiments, please refer to Figures 1 to 4, the support assembly 1 includes a left half 6 and a right half 7. The left half 6 is in a semi-circular ring shape, and its end is connected with a left locking member 8; the right half 7 is in a semi-circular ring shape, and its end is connected with a right locking member 9. The right locking member 9 is used to cooperate with the left locking member 8 for locking to fix the left half 6 and the right half 7. The distance between the left half 6 and the right half 7 is adjusted by means of the right locking member 9. By manually operating the right locking member 9, the right locking member 9 can cooperate with the left locking member 8 for locking and fixing. By adjusting the connection position between the right locking member 9 and the left locking member 8, the distance between the left half 6 and the right half 7 can be adjusted. The minimum distance is 0 mm, that is, the ends of the two are in contact with each other. The maximum distance is 8 mm. By adjusting the distance between the left half 6 and the right half 7, the locking and fixing on pipe piles with different diameters can be adapted, or it can be understood that it can embrace the outer wall of pipe piles within a certain diameter range. It should be noted that the distance between the center of the left half 6 and the center of the right half 7 is restricted. Both the left half 6 and the right half 7 embrace the outer wall of the pipe pile, and a gap is allowed to exist between the left half 6 and the right half 7 because for the outer diameter of the pre-stressed concrete pipe pile GB13476 - 2009 "Pretensioned Prestressed Concrete Pipe Piles", it is stipulated that the allowable deviation of pipe piles with an outer diameter of 300 mm - 700 mm reaches 5 mm. Therefore, a gap is allowed between the left half 6 and the right half 7. When the left half 6 and the right half 7 cannot surround and contact the outer wall of the pipe pile, gaskets, etc. can be attached to the inner walls of the left half 6 and the right half 7.

[0034] The left locking member 8 includes a nut-shaped structure. The right locking member 9 includes a sleeve-shaped structure and a bolt passing through this structure, and the bolt can be screwed with the left locking member 8. By screwing the bolt, it can be locked with the nut, and thus the left half 6 and the right half 7 can be fixed on the outer wall of the pipe pile.

[0035] In some embodiments, please refer to Figures 1 to 4 , the distance between the end of the left half 6 and the end of the right half 7 is less than or equal to 8 mm. When the ends of the left half 6 and the right half 7 are in contact with each other, and when the distance between the end of the left half 6 and the end of the right half 7 is 8 mm, both the left half 6 and the right half 7 can be fixed on the outer wall of the pipe pile. It's just that the mutual pressure or force between the support assembly 1 and the pipe pile can be adjusted, that is, the friction force of the support assembly 1 on the pipe pile can be adjusted.

[0036] In some embodiments, please refer to Figures 1 to 4 , both the left half 6 and the right half 7 are made of steel. Steel has magnetism and can be adsorbed by the welding robot 2.

[0037] In some embodiments, please refer to Figures 1 to 4, the welding robot 2 has a magnetic structure that can magnetically connect to the left half 6 or the right half 7. The magnetic structure is arranged at a position that does not affect the welding operation of the welding robot 2. The magnetic structure is connected to the left half 6 or the right half 7, so that the welding robot 2 can be fixed. When the welding robot 2 moves on the support assembly 1, it can be manually pushed to move, realizing the movement around the outer circumference of the pipe pile.

[0038] To enhance the self-structural strength of the left half 6 and the right half 7, in some embodiments, refer to Figures 1 to 4 , both the left half 6 and the right half 7 include a semi-circular ring-shaped outer shell 10 and a plurality of inner supports 11 connected to the inside of the outer shell 10. The plurality of inner supports 11 are arranged at equal intervals along the inner circumference of the outer shell 10. The outer shell 10 is made of steel material with relatively high structural strength. The function of the plurality of inner supports 11 inside is to prevent the outer shell 10 from deforming and improve the structural strength of the outer shell 10. Moreover, the position where the inner supports 11 are arranged does not affect the operation of the welding robot 2.

[0039] To reduce the weight of the left half 6 and the right half 7, in some embodiments, refer to Figures 1 to 4 , the inner supports 11 are made of aluminum. After the left half 6 and the right half 7 of the present utility model are in contact with each other, they can form a circular ring with an inner diameter of 608 mm and a weight of 20.5 kg. It is light in weight. To improve efficiency and reduce strength, it can be carried by a single person. When the left half 6 and the right half 7 are separated from each other, they are easy to disassemble and combine, which is convenient to use and facilitates the welding operation of the welding robot 2.

[0040] To prevent the welding robot 2 from accidentally falling during use, in some embodiments, refer to Figures 1 to 4 , the welding robot 2 is connected with a lifting rope 12, and the lifting rope is used to connect to a pipe pile driver (not shown in the figure). The pipe pile driver is a machine device for driving a pipe pile into the ground in the prior art. Connecting the lifting rope to the pipe pile driver can play a safety protection role for the welding robot 2 and ensure safe operation.

[0041] Regarding the specific operation process, parameter adjustment, etc. of the welding robot 2 in the present utility model, reference can be made to the prior art and will not be described herein. Attention should be paid to the adjustment of the distance between the nozzle and the pipe pile during welding, and the adjustment of the traveling direction and angle of the welding torch of the welding robot 2. The welding is carried out by using the carbon dioxide shielded welding method and the leftward welding method, which is convenient for observing the welding line, weld shape, gas protection effect, etc. In addition, it should be noted that the welding torch is clamped on the welding torch fixture, and a special wrench is used to adjust the operating angle and traveling angle of the welding torch.

[0042] In some embodiments, refer to Figures 1 to 4The welding robot 2 has a welding gun. During welding, the distance between the nozzle of the welding gun and the pipe pile is adjusted according to the welding current. When the welding current is below 200A, the distance between the nozzle and the pipe pile is set to 10-15mm; when the welding current is 200A-300A, the distance between the nozzle and the pipe pile is set to 15-20mm; when the welding current is 350A-500A, the distance between the nozzle and the pipe pile is set to 20-25mm.

[0043] In some embodiments, see Figures 1 to 4 The support assembly 1 is provided with a plurality of top screws 13, which are screwed to abut against the pipe pile to fix the support assembly 1 on the outer wall of the pipe pile. By screwing the top screws 13, the inner ends of the top screws 13 abut against the pipe pile, and the support assembly 1 can be fixed on the outer wall of the pipe pile.

[0044] The utility model can realize automatic welding of pipe piles. It takes about 4 minutes to weld a pipe pile with a diameter of 600mm using the welding robot 2. The welding speed can be adjusted. The welding robot 2 can also use the two-protection welding equipment that comes with the pipe pile machine. It is simple and easy to learn, and can realize fine-tuning during the welding process. The weld is full and uniform, which can meet the requirements of automatic welding and reduce the number of on-site welding personnel.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
