Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a welding device for building installation. Background Technology

[0002] Welding equipment for building installation is used in building installation projects to connect metal components, pipes, etc. With the acceleration of urbanization, a large number of infrastructure construction projects are emerging, which involve a large amount of welding work on steel structures, pipes, etc.

[0003] A search revealed that the document with publication number "CN216912760U" mentions that "this utility model relates to the field of building engineering technology and discloses a welding device for building installation, including an operating table. A mounting frame is provided on the top of the operating table, and welding components are provided on the inner top wall of the mounting frame. Two support components are provided on the top of the operating table, located inside the mounting frame and distributed horizontally. A rotating mechanism is provided on the top of the operating table, between the two support components, penetrating the support components and fixedly connected to them. Fixing mechanisms extending into the upper and lower sides of each support component are provided. This welding device for building installation, by setting the fixing mechanism, places a steel pipe inside a rotating drum between upper and lower clamping plates. Due to the tension of the spring, the clamping plates are pushed, causing the two..." The clamps fit snugly against the steel pipes, securing them and ensuring stability. This achieves the goal of stabilizing the structure and the steel pipes. The welding device for building installation uses a fixing mechanism to place the steel pipes inside a rotating drum between upper and lower clamps. Spring tension pushes the clamps, causing them to fit snugly against the steel pipes, thus securing them and ensuring stability. However, this device requires rotating the steel pipes at different positions during welding. Because the entire pipe is rotating, the heat-affected zone is relatively large, making it more prone to uneven thermal stress and increasing the likelihood of weld deformation. Furthermore, rotating large-diameter steel pipes requires greater torque and power, resulting in lower adaptability to different pipe types.

[0004] To address these issues, we provide a welding device for building installation. Utility Model Content

[0005] This application provides a welding device for building installation, which solves the problem that the device requires rotating the steel pipe itself to perform welding at different positions. Because the steel pipe is rotating as a whole, the heat-affected zone of the welding is relatively large, which makes it easier to generate uneven thermal stress and increases the possibility of deformation of the steel pipe during welding.

[0006] This application provides a welding device for building installation, including a base and a welding assembly. The welding assembly is mounted on the top of the base. The welding assembly includes a support frame fixedly connected to the top of the base. A limit ring is fixedly connected to one side of the support frame, and an auxiliary frame is fixedly connected to the other side of the limit ring.

[0007] Preferably, a first motor is mounted on the outside of the support frame, and a drive gear is connected to one end of the first motor via a key.

[0008] Preferably, a helical gear ring is meshed with the outer side of the drive gear, and the helical gear ring and the limiting ring form a rotating structure through a groove. A bracket is fixedly connected to the inner side of the helical gear ring.

[0009] Preferably, a movable block is slidably connected to the inner side of the bracket via a slot, a first electric telescopic rod is installed at the top of the movable block, and a welding torch body is installed at the top of the first electric telescopic rod.

[0010] Preferably, a second motor is installed on one side of the bracket, and an adjusting gear is connected to one end of the second motor via a flat key. A gear is meshed with the outer side of the adjusting gear, and the gear is fixedly connected to the moving block.

[0011] Preferably, a second electric telescopic rod is installed on the upper surface of the base, a C-shaped frame is fixedly connected to the top of the second electric telescopic rod, and auxiliary frames are fixedly connected to both sides of the C-shaped frame.

[0012] Preferably, a third electric telescopic rod is installed inside the auxiliary frame. One end of the third electric telescopic rod is fixedly connected to a push rod, and the other end of the push rod is fixedly connected to a clamping plate. A buffer friction pad is adhered to the other side of the clamping plate.

[0013] As can be seen from the above technical solution, this application provides a welding device for building installation. First, a steel pipe is placed on a C-shaped frame for support. A second electric telescopic rod is extended and adjusted to a vertical position. A third electric telescopic rod extends and moves a push rod in an auxiliary frame, causing the clamping plate and buffer friction pad to abut against the outside of the steel pipe, thus completing the clamping and fixing. Then, the first electric telescopic rod extends and moves to control the distance between the welding torch body and the weld seam of the steel pipe, and adapts to welding different types of steel pipes. Next, a second motor provides power to drive the adjusting gear to rotate, causing the gear rack to drive the moving block to slide in the bracket, adapting to weld seams in different positions. Finally, the first motor provides power to drive the drive gear to rotate, causing the rotating gear ring to drive the bracket to rotate, so that the welding torch body can work around the steel pipe. This completes the use of a welding device for building installation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A welding device that provides a fixed steel pipe and rotates around it via a welding assembly concentrates the heat-affected zone of the steel pipe near the weld, reducing the heat impact on other parts of the steel pipe, minimizing deformation and changes in microstructure caused by thermal stress, and exhibiting strong adaptability to different types of steel pipes. The first electric telescopic rod extends and retracts to control the distance between the welding torch body and the weld seam of the steel pipe, adapting to welding different types of steel pipes. The second motor provides power to drive the adjusting gear to rotate, causing the gear rod to drive the moving block to slide horizontally on the bracket, adapting to weld seams in different positions. The first motor provides power to drive the drive gear to rotate, causing the rotating gear ring to drive the bracket to rotate, enabling the welding torch body to rotate around the steel pipe for operation.

[0016] 2. By placing the steel pipe on the C-shaped frame for support, the second electric telescopic rod is adjusted to a vertical position, and the third electric telescopic rod extends and extends to drive the push rod to move horizontally in the auxiliary frame, so that the clamping plate and the buffer friction pad are pressed against the outside of the steel pipe to complete the clamping and fixing.
