Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, specifically to a welding device and welding method for components of a pile foundation casing lifting device. Background Technology

[0002] Patent CN218371273U discloses a lifting device for steel casing of slurry wall-supported cast-in-place piles, including a fixing assembly. The fixing assembly includes a support plate, support columns, a lifting plate, a first motor, a screw, a moving rod, a connecting plate, an inclined plate, a vertical plate, a fixing rod, a round rod, a fixing plate, and an arc-shaped plate. Four support columns are fixedly installed on the top of the support plate, and the lifting plate is fixedly installed at the end of the support columns. The first motor is fixedly installed on the top of the lifting plate, and the screw is rotatably installed on the bottom of the lifting plate.

[0003] In the aforementioned prior art, the hoisting is achieved by using a lifting steel cable from an external hoist to hang the ring, which facilitates quick fixation and saves a significant amount of time. However, when the ring is welded to the lifting plate, the inner wall of the ring is obscured by the outer wall, creating a relatively hidden welding area. Welders using welding guns will find it difficult to perform all-around welding around the ring as easily as when dealing with flat, straight seams. This not only increases the difficulty of welding but may also affect the welding quality. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a welding device and welding method for a pile foundation casing lifting device component.

[0005] This invention is implemented as follows: a welding device and welding method for a pile foundation casing lifting device component are constructed. The device includes a base, a top frame fixedly connected to the top of the base, a first linear actuator fixedly connected to one end of the top of the base, a guide rail fixedly connected to the top of the base, and a guide rail slidably connected to the inner side wall of the lower end of a placement plate. The output end of the first linear actuator is fixedly connected to the placement plate. An adjusting component is fixedly connected to the bottom of the top frame, and the lower end of the adjusting component is fixedly connected to the side wall of a first limiting frame. A first actuator is bolted to the bottom of the first limiting frame, and the output shaft of the first actuator is fixedly connected to the center of a first gear. The side wall of the first limiting frame is fixedly connected to the first actuator. The fixed connection has a first limiting ring, one end of which is hollowed out to form a through groove. The bottom side wall of the first limiting ring is hollowed out to form a sliding groove. A first gear ring is rotatably connected inside the first limiting ring. A first gear meshes with the first gear ring. The bottom of the first gear ring slides through the sliding groove via a connecting rod and is fixedly connected to the top of the second limiting ring. The placement plate is driven to slide on the guide rail by a first linear actuator, which can precisely adjust the position of the part to be welded and ensure the alignment accuracy during the welding process. The adjustment component allows the first limiting frame to be flexibly adjusted in the XYZ axes, further improving the accuracy and adaptability of the welding position.

[0006] According to the above technical solution, when the through grooves on the first limiting ring, the second limiting ring, the first gear ring, and the second gear ring are in the same position, the first limiting ring and the second limiting ring have a ring structure with a notch, so that the first limiting ring and the second limiting ring slide into the outer peripheral wall of the hanging ring through the notch and are rotatably arranged around the outer peripheral wall area of ​​the hanging ring.

[0007] According to the above technical solution, one end of the second limiting ring is hollowed out to form a through groove, a second toothed ring is slidably connected inside the second limiting ring, a second limiting frame is fixedly connected to the side wall of the second limiting ring, and a mating component is fixedly connected inside the second limiting frame.

[0008] According to the above technical solution, a robotic arm is fixedly connected to the side wall of the second gear ring, a welding gun is connected to the robotic arm, and a nozzle is fixedly connected to the side wall of the second gear ring.

[0009] According to the above technical solution, a through groove is provided on both the first gear ring and the second gear ring. The first driver is composed of a motor. The second linear driver, the third linear driver and the fourth linear driver are used to adjust the XYZ axis position of the first limiting frame. The cooperation between the first gear ring and the second gear ring and the first gear and the second gear enables the welding gun and nozzle to rotate and weld around the outer peripheral wall of the hanging ring, which can evenly cover the welding area and improve welding efficiency and quality.

[0010] According to the above technical solution, the mating assembly consists of a second driver and a second gear, and the second gear on the mating assembly meshes with the second gear ring.

[0011] According to the above technical solution, the adjustment component includes a second linear driver. A second linear driver is fixedly connected to the bottom of the top frame. The moving end of the second linear driver is fixedly connected to a third linear driver. The other end of the third linear driver is fixedly connected to a fourth linear driver. The moving end of the fourth linear driver is fixedly connected to the side wall of the first limiting frame.

[0013] S1: In the welding preparation stage, the workpiece needs to be placed securely on the top of the placement plate, and the hanging ring is connected to the workpiece. Then, the second linear driver, the third linear driver, and the fourth linear driver are controlled to drive the first limiting ring to move, so that the first limiting ring and the second limiting ring slide into the connection between the hanging ring and the workpiece through the through groove. The lower end of the first limiting ring and the hanging ring are coaxially set.

[0014] S2: Then the first driver is activated to drive the first gear to rotate, the first gear drives the first gear ring to rotate, the first gear ring drives the second limiting frame to rotate around the hanging ring for a period of time, and the second limiting frame drives the robotic arm and welding gun to rotate for the first time through the second limiting ring.

[0015] S3: Then, the control assembly drives the second gear ring to rotate. The second gear ring drives the robotic arm and welding gun to rotate a second time, so that the welding gun rotates around the hanging ring for one revolution and welds around the connection between the hanging ring and the workpiece.

[0016] S4: After welding is completed, the nozzle can be connected to the external spray pipe, and through the cooperation of the first gear ring and the second gear ring, the nozzle can be driven to perform 360-degree circular spraying around the weld between the hanging ring and the workpiece.

[0017] S5: After welding and spraying are completed, the through grooves on the first limiting ring, the second limiting ring, the first gear ring, and the second gear ring are overlapped. The fourth linear actuator drives the first limiting ring to move and disengage from the hanging ring.

[0018] The present invention has the following advantages: The present invention provides an improved welding device and welding method for components of a pile foundation casing lifting device, which, compared with similar equipment, has the following improvements:
