Description

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. At present, when two precast piles with end plates are spliced, it is necessary to weld the butt joints of the grooves on the outer edges of the end plates of the two precast piles by a welding torch.

[0003] In the prior art, pile splicing welding is generally carried out by manual welding, mobile welding trolley welding or special welding machine welding. Among them, in manual welding, the labor intensity is high, the welding quality is unstable, the welding efficiency is low, and there is exhaust gas emission, which affects the health of welders; when welding with a welding trolley, the environment in the pile driving area of the pile driver is very harsh, the ground conditions are poor, and the periphery of the precast pile is full of the supporting mechanism of the pile driver, so the welding trolley cannot enter and exit conveniently; when welding with a special welding machine, it is necessary to arrange a circular track on the precast pile, and the welding torch walks on the track to perform the welding task. However, this scheme can only adapt to circular precast piles. For precast piles with different diameters, it is necessary to continuously adjust the size of the circular track, so the operation preparation period is long and the applicable range is narrow. Therefore, the existing pile splicing welding schemes all have problems such as narrow applicable range, complex operation and poor welding quality. Summary of the Utility Model

[0028] The embodiments of the present utility model will be described in detail below.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0029] As Figure 1 and Figure 2 shown, this embodiment provides a welding device for butt-welding two precast piles 71 on a pile driver 7.

[0030] The welding device includes a fixed seat 1, a robotic arm 2, and a welding torch 3. A first magnetic attracting member 11 is provided on the fixed seat 1. The fixed seat 1 is magnetically attracted to the pile driver 7 through the first magnetic attracting member 11. The robotic arm 2 is arranged on the fixed seat 1, and the welding torch 3 is arranged at the driving end of the robotic arm 2, so that the robotic arm 2 can drive the welding torch 3 to move for butt welding of two precast piles 71. The fixed seat 1 of this welding device can be directly fixed on the pile driver 7, and the welding torch 3 is moved by the robotic arm 2 to weld the two precast piles 71. Therefore, there is no need to move the entire welding device, and it is not affected by the surrounding environment of the pile driving area of the pile driver 7. At the same time, the robotic arm 2 can adjust the welding path of the welding torch 3 according to requirements. Therefore, the operation preparation cycle of this welding device is short, the operation is simple, the applicable range is wide, the operation effect is high, the welding quality is stable, and automatic welding can be achieved. Among them, the fixed seat 1 is magnetically attracted to the pile driver 7 through the first magnetic attracting member 11, so that the disassembly and assembly of the welding device are simple, convenient for transportation, maintenance, and storage. The entire welding device is not affected by any ground environment and can quickly start welding operations when reaching a new working position.

[0031] Specifically, the robotic arm 2 is a collaborative robotic arm. There are at least two collaborative robotic arms, and at least two collaborative robotic arms are respectively located at opposite ends of the precast pile 71 along the horizontal direction. Thus, through the cooperation of the two collaborative robotic arms, the butt welding efficiency of the two precast piles 71 can be increased. Optionally, the precast pile 71 is a round pile, a square pile, or a special-shaped pile.

[0032] Furthermore, the welding device further includes a fixing frame 4. A second magnetic attracting member 41 is provided on the fixing frame 4. The fixing frame 4 is magnetically attracted to the pile driver 7 through the second magnetic attracting member 41. A wire feeder 42 is also provided on the fixing frame 4. The wire feeding pipe 421 of the wire feeder 42 is connected to the welding torch 3. Thus, the fixing frame 4 of this welding device can be directly fixed on the pile driver 7, so that it is convenient for the wire feeder 42 to supply welding wire to the welding torch 3 through the wire feeding pipe 421, reducing the wire feeding difficulty, avoiding interference of the support mechanism around the pile driving area of the pile driver 7 on the wire feeding pipe 421, and avoiding damage to the robotic arm 2 caused by winding of the wire feeding pipe 421 during the movement of the robotic arm 2. Moreover, the fixing frame 4 is magnetically attracted to the pile driver 7 through the second magnetic attracting member 41, so that the fixing frame 4 and the devices on the fixing frame 4 are simple to disassemble and assemble, convenient for transportation, maintenance, and storage. Optionally, the welding device further includes a fixing bracket 5. Both ends of the fixing bracket 5 are respectively connected to the robotic arm 2 and the wire feeding pipe 421. Thus, the position of the wire feeding pipe 421 can be further limited through the fixing bracket 5, so that the wire feeding pipe 421 can move with the robotic arm 2, preventing the wire feeding pipe 421 from winding around the robotic arm 2 and at the same time preventing the wire feeding pipe 421 from dragging on the ground.

[0033] Further, a control cabinet 43 and a teaching pendant 44 are also provided on the fixing frame 4. Setting the control cabinet 43 and the teaching pendant 44 on the fixing frame 4 can make reasonable use of space. At the same time, the control cabinet 43 is communicatively connected to the teaching pendant 44 and the robotic arm 2. Thus, the robotic arm 2 can be controlled through the teaching pendant 44 and the control cabinet 43 to realize operations, programming, debugging, monitoring, etc. of the robotic arm 2. Specifically, both the fixing base 1 and the fixing frame 4 are provided at the lower end of the pile driver 7. Thus, the robotic arm 2, the wire feeder 42, the control cabinet 43, and the teaching pendant 44 are all located below the pile driver 7, which facilitates the installation of the robotic arm 2, the wire feeder 42, the control cabinet 43, and the teaching pendant 44. At the same time, it is convenient for the staff to operate the robotic arm 2, the wire feeder 42, the control cabinet 43, and the teaching pendant 44.

[0034] Further, the welding device further includes a power supply base 6. A third magnetic attraction member 61 is provided on the power supply base 6. The power supply base 6 is magnetically attracted to the pile driver 7 through the third magnetic attraction member 61. A welding power supply 62 is also provided on the power supply base 6. The welding power supply 62 is electrically connected to the wire feeder 42 and the welding torch 3. Thus, the power supply base 6 of the welding device can be directly fixed on the pile driver 7, which facilitates the installation of the welding power supply 62 and the welding power supply 62 to supply electrical energy to the wire feeder 42 and the welding torch 3. The wire feeder 42 and the welding torch 3 do not require external circuit power supply, thus avoiding the influence of external circuits on the robotic arm 2 and the pile driver 7. Moreover, the power supply base 6 is magnetically attracted to the pile driver 7 through the third magnetic attraction member 61. Thus, the power supply base 6 and the devices on the power supply base 6 are simple to disassemble and assemble, convenient for transportation, and convenient for maintenance and storage. Optionally, the first magnetic attraction member 11, the second magnetic attraction member 41, and the third magnetic attraction member 61 are all switch-type magnetic chucks. At the same time, a shielding gas cylinder 63 is also provided on the power supply base 6. The shielding gas cylinder 63 is connected to the wire feeder 42 through a pipeline to supply shielding gas to the welding torch 3 through the wire feeder 42, thus protecting the welding quality. Optionally, the power supply base 6 is provided with a lifting lug. The power supply base 6 can be hoisted on the upper end of the pile driver 7 through the lifting lug, so that the pile driver 7 can carry the power supply base 6 and the heavier devices on the power supply base 6, avoiding potential safety hazards caused by the falling of the power supply base 6.

[0035] This embodiment also provides a pile driver, as Figure 1 shown, including the welding device as described above. By using the welding device as described above, the pile driver 7 can, while realizing the pile driving function, also perform pile splicing welding on the precast pile 71, which facilitates reasonable planning of the process flow and improves the operation efficiency.

[0036] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
