Therefore, it is urgent to develop a main beam force pipe welding device that can overcome the above problems. Summary of the Invention

[0003] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide a main beam force pipe welding device, which realizes efficient, stable and universal welding operations through a split welding frame, a precise guiding structure and an adjustable mounting component.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a main beam force pipe welding device, including: A bracket, on which there are two fixing positions for installing the main beam force pipe. When the main beam force pipe is installed on the fixing position, the connecting part of the two main beam force pipes can form a circumferential weld seam to be welded on the bracket; A welding frame, which is installed on the bracket; Among them, a welding torch that moves along a preset track is installed on the welding frame. The welding frame is sleeved outside the main beam force pipe, and the end of the welding torch can perform circumferential movement along the weld seam for welding. The welding frame is a split structure. When the two split parts of the welding frame are separated, the distance between the two split parts is greater than the width of the main beam force pipe.

[0005] Preferably, the two split parts are respectively a first arc body and a second arc body.

[0024] The following uses specific embodiments to illustrate the present invention, but it does not limit the invention.

[0025] Embodiment 1 As Figures 1 - 8 shown, in this embodiment, a main beam force pipe welding device is provided, including a bracket 1 and a welding frame 2.

[0026] There are two fixed positions on the bracket 1 for installing the main beam force pipes. When the main beam force pipes are installed on the fixed positions, the connecting parts of the two main beam force pipes can form a circumferential weld to be welded on the bracket 1. First, the two main beam force pipes are respectively installed on the two fixed positions of the bracket 1, so that the connecting parts of the main beam force pipes form a circumferential weld to be welded on the bracket 1. Then, the welding frame 2 is installed on the bracket 1. Since the welding frame 2 is sleeved outside the main beam force pipes, and the welding torch 3 is installed on the welding frame 2 and can move along a preset track, by controlling the welding torch 3, its end moves circumferentially along the weld, thus completing the welding work of the circumferential weld of the main beam force pipes. There is a fixing plate 8 installed on the bracket 1. The upper end of the fixing plate 8 is provided with a groove adapted to the main beam force pipes. There is a pressing plate 7 for pressing the main beam force pipes on the fixing plate 8. The pressing plate 7 can be fixed on the fixing plate 8 by bolts or other fastening methods. By adjusting the fastening degree, it is ensured that the main beam force pipes are firmly fixed on the bracket 1. The combined use of the fixing plate 8 and the pressing plate 7 provides a reliable fixing method for the main beam force pipes installed on the bracket 1, effectively preventing the main beam force pipes from being displaced due to factors such as vibration and external forces during the welding process, ensuring the accuracy of the welding position, thereby improving the welding quality and efficiency, and at the same time enhancing the stability of the entire welding device.

[0027] The welding frame 2 is installed on the bracket 1. There is a welding torch 3 moving along a preset track installed on the welding frame 2. The welding frame 2 is sleeved outside the main beam force pipes, and the end of the welding torch 3 can move circumferentially along the weld for welding. The welding frame 2 is a split structure. When the two split parts of the welding frame 2 are separated, the distance between the two split parts is greater than the width of the main beam force pipes, which is convenient for the installation and disassembly of the main beam force pipes. The fixed positions can stably fix the main beam force pipes and ensure accurate positions during welding; the welding frame 2 and the movable welding torch 3 realize the automatic welding of the circumferential weld, improving the welding efficiency and quality; the split structure design of the welding frame 2 greatly facilitates the loading and unloading of the main beam force pipes.

[0028] Embodiment 2 As Figures 1 - 8 shown, on the basis of Embodiment 1, this embodiment provides the structure of the welding frame 2, which is specifically as follows: The two split parts are the first arc-shaped body 201 and the second arc-shaped body 202 respectively. The first arc-shaped body 201 and the second arc-shaped body 202 are respectively slidably mounted on the bracket 1 through the carriage 5. Moving channels are provided inside both the first arc-shaped body 201 and the second arc-shaped body 202. The welding torch 3 can move inside the moving channels. The moving channels divide the first arc-shaped body 201 and the second arc-shaped body 202 into two symmetrical parts. When it is necessary to install or disassemble the main beam force pipe, the first arc-shaped body 201 and the second arc-shaped body 202 can be slid apart on the bracket 1 through the carriage 5; during welding, they are slid together. At this time, the moving channels divide the first arc-shaped body 201 and the second arc-shaped body 202 into two symmetrical parts. The welding torch 3 moves along the moving channels to weld the weld seam. The split sliding structure of the first arc-shaped body 201 and the second arc-shaped body 202 further reduces the difficulty of installing and disassembling the main beam force pipe compared with the integral structure, and improves the flexibility of operation; the setting of the moving channels provides guidance and support for the movement of the welding torch 3, ensuring that the welding torch 3 can move along a predetermined trajectory.

[0029] Guiding channels are provided inside both the first arc-shaped body 201 and the second arc-shaped body 202. The number of guiding channels is two. The welding torch 3 is installed inside the moving body 4. The moving body 4 includes an insertion rod 41 inserted into the moving channel. A protrusion 42 adapted to the guiding channel is installed on the insertion rod 41. The protrusion 42 moves along the corresponding guiding channel. During the welding process, the moving body 4 drives the welding torch 3 to move, and the protrusion 42 moves along the corresponding guiding channel, thereby guiding the moving body 4 and the welding torch 3 to move inside the first arc-shaped body 201 and the second arc-shaped body 202 along a predetermined direction, ensuring that the welding torch 3 welds the weld seam stably. The cooperation of the guiding channels and the protrusion 42 provides precise guidance for the movement of the welding torch 3, restricts the movement of the welding torch 3 in non-welding directions, avoids the welding torch 3 deviating from the weld seam, and improves the welding precision and quality.

[0030] The shape of the protrusion 42 is spherical, and the guiding channel is adapted to the protrusion 42. During the process of the moving body 4 driving the welding torch 3 to move, the spherical protrusion 42 rolls inside the guiding channel, enabling the moving body 4 to move more smoothly inside the guiding channel, reducing the frictional resistance during the movement. At the same time, the spherical protrusion 42 can adapt to slight deviations of the guiding channel to a certain extent. The adapted design of the spherical protrusion 42 and the guiding channel reduces the frictional force when the moving body 4 moves, makes the movement of the welding torch 3 more flexible and stable, reduces mechanical wear, and extends the service life of the device.

[0031] The movable body 4 also includes a slider 43 fixed to the end of the insertion rod 41, and a roller 44 is installed on the slider 43. The outside of the first arc body 201 and the second arc body 202 are provided with a raceway 203 adapted to the roller 44, and the roller 44 is rotatably installed inside the raceway 203. The motor drives the roller 44 to rotate, and the roller 44 rolls inside the raceway 203, thereby driving the movable body 4 to move outside the first arc body 201 and the second arc body 202, thereby making the welding gun 3 installed inside the movable body 4 move circumferentially along the weld seam for welding. The rolling coordination of the roller 44 and the raceway 203 further reduces the friction resistance of the movable body 4 during movement, and improves the efficiency and stability of the movement of the welding gun 3; the motor drives the roller 44 to rotate, thereby realizing the automatic control of the movement of the welding gun 3, and can more accurately control the moving speed and trajectory of the welding gun 3 compared to manual operation.

[0032] A motor for driving the roller 44 to rotate is fixed on the mobile body 4, which is driven to rotate by the transmission device. The roller 44 rolls in the raceway 203, thereby driving the mobile body 4 to move along the outside of the first arc body 201 and the second arc body 202, so that the welding gun 3 welds along the weld seam according to a predetermined trajectory and speed. The motor serves as a power source and provides a stable and controllable driving force for the movement of the welding gun 3. The motor can accurately adjust the speed and direction of the motor according to different welding process requirements, thereby controlling the moving speed and direction of the welding gun 3.

[0033] Example 3 like Figures 1 - 8 As shown, based on the first and second embodiments, this embodiment provides a moving method of the slide 5, which is as follows: The slide 5 includes a vertical rod 51 and a horizontal rod 52. The first arc body 201 and the second arc body 202 are respectively fixed at the corresponding horizontal rod 52. A clearance groove is provided on the horizontal rod 52. When the position of the first arc body 201 and the second arc body 202 needs to be adjusted, the vertical rod 51 of the slide 5 is inserted into the slide groove of the bracket 1. The vertical rod 51 can slide in the slide groove through the action of external force, thereby driving the horizontal rod 52 and the first arc body 201 and the second arc body 202 fixed on the horizontal rod 52 to move. The design of the slide 5 enables the first arc body 201 and the second arc body 202 to move flexibly on the bracket 1, which is convenient for adjusting the position of the welding frame 2 according to different specifications of the main beam force tube or welding requirements; the setting of the clearance groove avoids the interference of components during the welding process and affects the normal progress of the welding work.

[0034] The support 1 is provided with a sliding groove, the vertical rod 51 is inserted into the interior of the sliding groove, a screw rod 6 is rotatably installed inside the sliding groove, the lower end of the vertical rod 51 is slidably installed in the sliding groove, a threaded hole adapted to the screw rod 6 is provided at the lower end of the vertical rod 51, the screw rod 6 passes through and meshes with the threaded hole. When the screw rod 6 is rotated, the screw rod 6 meshes with the threaded hole, and the rotation of the screw rod 6 will be converted into the up and down movement of the vertical rod 51 in the sliding groove, thereby driving the cross bar 52 and the first arc body 201 and the second arc body 202 fixed on the cross bar 52 to move up and down, realizing the precise adjustment of the height of the welding frame 2. By adjusting the height of the welding frame 2 in the way of driving by the screw rod 6, the operation is simple and the adjustment precision is high, which can meet the welding requirements of main beam force pipes with different height specifications and improve the versatility of the device.

[0035] Inner grooves are provided inside both the first arc body 201 and the second arc body 202. When the first arc body 201 and the second arc body 202 are connected together, the two inner grooves form a passage for the main beam force pipe to pass through. When installing the main beam force pipe, the main beam force pipe is passed through the passage so that the main beam force pipe is located at a suitable position inside the welding frame 2, and then welding is carried out; when disassembling, the first arc body 201 and the second arc body 202 are separated, and the main beam force pipe can be taken out from the passage. The passage formed by the inner grooves provides convenience for the installation and disassembly of the main beam force pipe. At the same time, during the welding process, it plays a certain role in positioning and supporting the main beam force pipe, ensuring the accurate position of the main beam force pipe during welding and preventing the main beam force pipe from shifting during welding.

[0036] Working principle: This main beam force pipe welding device realizes the efficient and precise welding of the main beam force pipe through the coordinated operation of the support 1, the welding frame 2 and related components. In the initial installation stage, two main beam force pipes are installed by using the two fixed positions on the support 1, so that the connection part of the main beam force pipes forms a circumferential weld to be welded on the support 1. At the same time, the welding frame 2 is installed on the support 1. Since the welding frame 2 is a split structure (the first arc body 201 and the second arc body 202), the two split parts can be separated first during installation. After separation, the distance between the two is greater than the width of the main beam force pipe, which is convenient for placing the main beam force pipe. After placing, the first arc body 201 and the second arc body 202 are slidably spliced, and at this time the welding frame 2 is sleeved outside the main beam force pipe. During the welding process, the welding torch 3 is installed in the moving channel inside the welding frame 2. The moving channel is composed of the internal structures of the first arc body 201 and the second arc body 202, which divides the two into two symmetrical parts, providing space for the movement of the welding torch 3. The welding torch 3 is installed inside the moving body 4. The insertion rod 41 of the moving body 4 is inserted into the moving channel. The spherical protrusions 42 on the insertion rod 41 are adapted to the two guiding channels inside the first arc body 201 and the second arc body 202. During welding, the protrusions 42 move along the guiding channels, guiding the moving body 4 and the welding torch 3 to move inside the welding frame 2 along a predetermined direction, ensuring that the welding torch 3 moves stably along the weld seam. At the same time, the rollers 44 on the end slider 43 of the moving body 4 cooperate with the external raceway 203 of the welding frame 2. The motor on the moving body 4 drives the rollers 44 to rotate. The rollers 44 roll in the raceway 203, driving the moving body 4 to move outside the welding frame 2, and further enabling the welding torch 3 to perform a circumferential movement along the weld seam, completing the welding work of the circumferential weld seam. In the adjustment section, the welding frame 2 is installed on the bracket 1 through the sliding frame 5. The sliding frame 5 is composed of a vertical rod 51 and a horizontal rod 52. The relief groove on the horizontal rod 52 can avoid interference of components during the welding process. The vertical rod 51 is inserted into the chute of the bracket 1. By rotating the screw rod 6 meshing with the screw hole at the lower end of the vertical rod 51 inside the chute, the vertical rod 51 can move up and down, driving the horizontal rod 52 and the first arc body 201 and the second arc body 202 fixed on the horizontal rod 52 to move up and down, realizing precise adjustment of the height of the welding frame 2 to meet the welding requirements of main beam force pipes of different specifications. In addition, the inner grooves inside the first arc body 201 and the second arc body 202 form a channel through which the main beam force pipe passes when spliced, facilitating the installation, positioning and disassembly of the main beam force pipe; the fixing plate 8 and the pressing plate 7 on the bracket 1 further press and fix the main beam force pipe, preventing the main beam force pipe from shifting during welding and ensuring the accuracy of the welding position. Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
