Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically, to a synchronous correction device and system for welding circular T-shaped parts. Background Technology

[0002] A T-shaped ring is generally a ring-shaped reinforcing rib with a T-shaped cross-section. It is typically fitted onto the outer wall of a cylindrical container to reinforce it. For example, to improve the overall rigidity of a cylindrical petrochemical container, a complete ring T-shaped component needs to be welded to the outer wall. The ring T-shaped component is usually cut by flame cutting or laser cutting. The outer wall of the cylindrical section of the petrochemical container has a curved structure, and there is a certain deviation in the roundness of both during the manufacturing process. This results in gaps between the ring T-shaped component and the cylindrical section after assembly, affecting the welding quality. At the same time, the heat deformation of the ring T-shaped component during welding can also cause gaps or further enlargement of the gaps.

[0003] Currently, in order to avoid the above situation, during the welding process of the ring T-shaped parts, it is generally necessary to stop the welding operation from time to time, and then correct the shape of the ring T-shaped parts and the gap between the ring T-shaped parts and the cylinder section. However, this may not only affect the welding quality of the previous stage, but also increase the labor intensity of the operators and reduce the efficiency of the welding operation. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to improve the welding quality and efficiency of the circular T-shaped parts.

[0005] This invention provides a synchronous correction device for welding circular T-shaped parts, including a welding carriage, a hydraulic lifting support, and a rotating roller. The rotating roller is used to support and rotate the cylindrical section. The welding carriage includes a carriage body, a welding torch holder, and rollers. The welding torch holder is connected to the carriage body and is used to mount the welding torch. The rollers are rotatably connected to the carriage body and are used to roll and connect to the outer circumferential wall of the circular T-shaped part. The top end of the hydraulic lifting support is used to abut against the bottom end of the carriage body and is used to lift the carriage body.

[0006] Optionally, the roller is provided with rims at both axial ends, and the rims are used to abut against the side ends of the outer circumferential wall of the annular T-shaped member.

[0007] Optionally, the synchronous correction device for welding the circular T-shaped part further includes a locking ring, which is used to be sleeved on the cylindrical section, and the welding trolley is used to be positioned between the locking ring and the cylindrical section.

[0008] Optionally, the welding trolley further includes a traveling wheel adapted to the locking ring, the traveling wheel being rotatably connected to the bottom end of the trolley body, and the traveling wheel being used to roll and connect the locking ring.

[0009] Optionally, the two locking rings are respectively fitted onto the cylindrical section, and the two sets of traveling wheels are respectively rotatably connected to the opposite sides of the bottom end of the vehicle body, and the two sets of traveling wheels are respectively used to roll and connect the two locking rings.

[0010] Optionally, the welding trolley further includes a magnetic adsorption component, which is connected to the top of the trolley body and is used to magnetically attach to the cylindrical section.

[0011] Optionally, the welding trolley further includes a weld seam tracking component connected to the top of the trolley body for monitoring the weld seam between the cylindrical section and the annular T-shaped component.

[0012] Optionally, the hydraulic lifting support includes a hydraulic cylinder and a base. The base is connected to the cylinder body of the hydraulic cylinder and is used to connect to the base. The telescopic end of the hydraulic cylinder is detachably connected to the bottom end of the vehicle body.

[0013] Optionally, the hydraulic jacking support further includes a pressure gauge, which is installed in the hydraulic cylinder to detect the pressure of the hydraulic cylinder.

[0014] Compared with the prior art, the synchronous correction device for welding circular T-shaped parts provided by the present invention has the following technical effects:

[0015] The circular T-shaped component welding synchronous correction device provided by this invention, by setting a rotating roller, allows the cylindrical section of the container to be processed to be placed on the rotating roller, and the cylindrical section can be rotated by driving the rotating roller. When welding the circular T-shaped component, the circular T-shaped component can be pre-fitted onto the outer wall of the cylindrical section, and the roller of the welding carriage abuts against the outer circumferential wall of the circular T-shaped component. At the same time, the hydraulic lifting support is connected to the bottom end of the welding carriage body, and the carriage body is lifted and rotatedly connected to the carriage body through the roller. As the cylindrical section is rotated by the rotating roller, the roller of the welding carriage can roll the outer circumferential wall of the circular T-shaped component, thereby correcting the shape of the circular T-shaped component and avoiding gaps between the circular T-shaped component and the cylindrical section. At the same time, by setting a welding gun bracket on the carriage body, a welding gun can be installed on the welding gun bracket, and welding can be performed as the cylindrical section rotates. With the above structural design, correction can be performed simultaneously during the welding process of the circular T-shaped parts, which improves the welding quality of the circular T-shaped parts, reduces the labor intensity of the operators, and improves the efficiency of welding operations.

[0016] In addition, the present invention also provides a synchronous correction system for welding circular T-shaped parts, including a controller and the above-mentioned synchronous correction device for welding circular T-shaped parts. The controller is electrically connected to the welding carriage, hydraulic lifting support and rotating roller of the synchronous correction device for welding circular T-shaped parts.

[0017] Compared with the prior art, the synchronous correction system for welding ring T-shaped parts provided by the present invention, by setting up a controller and a synchronous correction device for welding ring T-shaped parts, has roughly the same technical effect as the aforementioned synchronous correction device for welding ring T-shaped parts, which will not be repeated here. At the same time, by setting up a controller and electrically connecting it to the welding carriage, hydraulic jacking support and rotating roller of the synchronous correction device for welding ring T-shaped parts, the welding carriage, hydraulic jacking support and rotating roller can be automatically controlled and adjusted, which is conducive to realizing automated operation and further improving the quality and efficiency of welding operation.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0027] To solve the above technical problems, such as Figure 1 and Figure 2 As shown, this embodiment of the invention provides a synchronous correction device for welding a circular T-shaped part, including a welding carriage 10, a hydraulic lifting support 20, and a rotating roller 30. The rotating roller 30 is used to support and rotate the cylindrical section 01. The welding carriage 10 includes a carriage body 11, a welding torch support 12, and rollers 13. The welding torch support 12 is connected to the carriage body 11 and is used to mount the welding torch. The rollers 13 are rotatably connected to the carriage body 11 and are used to roll and connect to the outer circumferential wall of the circular T-shaped part 02. The top end of the hydraulic lifting support 20 is used to abut against the bottom end of the carriage body 11 and is used to lift the carriage body 11.

[0028] It should be noted that the cylindrical section 01 refers to the cylindrical section 01 of a cylindrical container, such as... Figure 1As shown, the cylindrical section 01 is the cylindrical section 01 of a petrochemical container, with a central cylindrical structure. The annular T-shaped component 02 is an integrally annular rib structure with a T-shaped cross-section. To improve the rigidity and structural strength of the petrochemical container, the annular T-shaped component 02 needs to be welded and fixed to its outer wall. The part of the annular T-shaped component 02 welded to the cylindrical section 01 is the bottom part of the T-shaped structure of the annular T-shaped component 02, that is, the inner circumference of the annular T-shaped component 02. The part of the annular T-shaped component 02 that is rolled and connected to the roller 13 of the welding carriage 10 is its outer circumference, that is, the flat top part of the T-shaped structure, making the rolling process more stable and reliable. At the same time, two sets of rotating rollers 30 can be provided, which makes the support and driving of the cylindrical section 01 rotation more reliable, and the rollers themselves can rotate. For example, they can be equipped with a motor connected to a gearbox to drive the rollers to rotate, thereby driving the cylindrical section 01 placed on them to rotate. Furthermore, the shape and structure of the body 11 of the welding carriage 10 can be designed according to actual needs. For example, the body 11 has a groove to accommodate and install the roller 13. The roller 13 can be rotatably connected by installing a rotating shaft in the groove of the body 11. A wear-resistant and lubrication-enhancing bushing can be installed on the rotating shaft, such as a bushing made of copper alloy and coated with graphite. In order to prevent the heat generated during welding from affecting other components, the body 11 can also be covered with heat-insulating materials such as asbestos board and aluminum foil for heat insulation and protection, thereby improving the overall service life and reliability. At the same time, the welding torch holder 12 can be a clamp-type structure or a threaded connection structure for installing and fixing the welding torch. The welding torch can be selected according to the actual welding operation needs, and its relative position with the welding torch holder 12 can also be adjusted according to the actual welding conditions.

[0029] In this embodiment, the synchronous correction device for welding the circular T-shaped part provides a rotating roller 30 on which the cylindrical section 01 of the container to be processed can be placed. The rotating roller 30 can be driven to rotate the cylindrical section 01. When welding the circular T-shaped part 02, the circular T-shaped part 02 can be pre-fitted onto the outer wall of the cylindrical section 01, and the rollers 13 of the welding carriage 10 abut against the outer circumferential wall of the circular T-shaped part 02. At the same time, the hydraulic lifting support 20 is connected to the body 11 of the welding carriage 10. The bottom end is connected and the vehicle body 11 is lifted. Rollers 13 are rotatably connected to the vehicle body 11. As the rotating rollers 30 drive the cylinder section 01 to rotate, the rollers 13 of the welding carriage 10 roll over the outer circumference of the ring-shaped T-part 02, thereby correcting the shape of the ring-shaped T-part 02 and preventing gaps between it and the cylinder section 01. Simultaneously, a welding torch holder 12 is installed on the vehicle body 11, which can hold the welding torch and perform welding as the cylinder section 01 rotates. Through this structural arrangement, correction can be performed simultaneously during the welding of the ring-shaped T-part 02, improving the welding quality, reducing the labor intensity of operators, and increasing welding efficiency.

[0030] Optionally, such as Figure 2 As shown, the roller 13 has rims at both axial ends, and the rims are used to abut against the side ends of the outer circumferential wall of the annular T-shaped part 02.

[0031] Specifically, two rollers 13 can be installed on the vehicle body 11, and they can be arranged according to the curvature of the circular T-shaped part 02 as needed. This allows for more stable rolling correction of the circular T-shaped part 02, resulting in better correction and more stable and reliable operation.

[0032] In this embodiment, by setting rims at both ends of the roller 13 along its axial direction, and during use, the rims can abut against the side of the outer circumferential wall of the ring T-shaped part 02. In other words, the two rims of the roller 13 along its axial direction can restrict the axial movement of the ring T-shaped part 02, thereby enabling more reliable and stable correction of the ring T-shaped part 02 and making its operation more stable.

[0033] Optionally, such as Figure 1 and Figure 2 As shown, the synchronous correction device for welding the circular T-shaped part further includes a locking ring 40, which is used to be sleeved on the cylindrical section 01, and the welding trolley 10 is used to be positioned between the locking ring 40 and the cylindrical section 01.

[0034] Specifically, the locking ring 40 can be a structure such as a steel wire rope or iron chain, and its tightness can be adjusted to ensure that the welding carriage 10 is stably clamped between the locking ring 40 and the cylinder section 01, that is, to keep the welding carriage 10 in close contact with the cylinder section 01 at all times, so as to improve the stability and reliability of welding and correction.

[0035] In this embodiment, by setting a locking ring 40 and sleeved on the cylindrical section 01, during use, by placing the welding carriage 10 between the locking ring 40 and the cylindrical section 01, the welding carriage 10 can be stably clamped to the outer circumferential wall surface of the cylindrical section 01 by the locking ring 40, thereby improving the stability of welding and the correction of the circular T-shaped part 02.

[0036] Optionally, such as Figure 2 As shown, the welding trolley 10 also includes a traveling wheel 14 adapted to the locking ring 40. The traveling wheel 14 is rotatably connected to the bottom end of the trolley body 11 and is used to roll the locking ring 40.

[0037] Specifically, the welding trolley 10 can also be configured to automatically travel on the outer circumferential wall of the cylindrical section 01. For example, the welding trolley 10 may include a walking mechanism driven by a motor, such as the motor driving the walking wheel 14 to rotate. The walking wheel 14 travels on the locking ring 40. At this time, the connection between the hydraulic lifting support and the trolley body 11 can be released, and the operation of the rotating roller 30 can be stopped. The cylindrical section 01 can not rotate, and the welding trolley 10 moves around the circumference of the cylindrical section 01. Under the clamping state of the locking ring 40, it can automatically perform welding and synchronous correction operations, further improving the work efficiency.

[0038] In this embodiment, by rotating and connecting the walking wheel 14 to the bottom of the welding carriage 10, the walking wheel 14 can be rolled and connected to the locking ring 40 during use. On the one hand, this makes the rotating welding operation and synchronous correction operation smoother and more stable. On the other hand, it also facilitates the realization of automatic walking, automatic welding and correction operation mode, which is conducive to further improving operation efficiency and quality.

[0039] Specifically, such as Figure 2 As shown, the two locking rings 40 are respectively used to be sleeved on the cylindrical section 01, and the two sets of traveling wheels 14 are respectively rotatably connected to the opposite sides of the bottom end of the vehicle body 11, and the two sets of traveling wheels 14 are respectively used to roll and connect the two locking rings 40.

[0040] In this embodiment, by setting two sets of walking wheels 14 and rolling them onto two locking rings 40 respectively, the overall stability is further improved, preventing the welding carriage 10 from tipping over and falling off, making the overall operation more stable and reliable.

[0041] Optionally, such as Figure 2 As shown, the welding trolley 10 also includes a magnetic adsorption component 15, which is connected to the top of the trolley body 11 and is used to magnetically attach to the cylindrical section 01.

[0042] Specifically, the magnetic adsorption component 15 can be an electromagnetic structure, for example, it can be powered by a controller to generate a magnetic force after being powered on, and can be adsorbed on the outer circumferential wall of the cylindrical section 01. Preferably, the part of the magnetic adsorption component 15 that contacts the cylindrical section 01 is a wheel-shaped structure, which can minimize the friction between the magnetic adsorption component 15 and the cylindrical section 01, so that the relative movement between the welding carriage 10 and the cylindrical section 01 is smoother while preventing the welding carriage 10 from falling off the cylindrical section 01.

[0043] In this embodiment, by connecting a magnetic adsorption component 15 to the top of the vehicle body, the magnetic adsorption component 15 can be adsorbed onto the cylindrical section 01 during use, preventing the welding carriage 10 from falling off. At the same time, it can further improve the reliability of the welding carriage 10 in correcting the circular T-shaped part 02, thereby further improving the quality of the welding operation.

[0044] Optionally, such as Figure 2 As shown, the welding trolley 10 also includes a weld seam tracking component 16, which is connected to the top of the trolley body 11 and is used to monitor the weld seam between the cylindrical section 01 and the annular T-shaped part 02.

[0045] Specifically, this synchronous correction device for welding ring T-shaped parts can be configured with a control system such as a controller. Meanwhile, the weld seam tracking component 16 can be, for example, a laser sensor or an optical sensor, and can be used in conjunction with an image processing module. For example, the controller receives and processes the weld seam condition between the cylinder section 01 and the ring T-shaped part 02 monitored by the weld seam tracking component 16, providing a more accurate welding path for the welding torch. Of course, the welding torch path can be adjusted manually or automatically in real time by connecting to the controller through an automatic adjustment mechanism. No specific limitation is made here, which can further improve the efficiency of the operation.

[0046] In this embodiment, by setting a weld seam tracking component 16 at the top of the vehicle body 11, the weld seam tracking component 16 can monitor the weld seam between the cylinder section 01 and the ring T-shaped part 02 during use, which can provide operators or operating systems with a better and more accurate welding operation path and instructions, which is conducive to further improving the quality of welding operations.

[0047] Optionally, such as Figure 1 and Figure 2As shown, the hydraulic lifting support 20 includes a hydraulic cylinder and a base 21. The base 21 is connected to the cylinder body of the hydraulic cylinder and is used to connect to the base. The telescopic end of the hydraulic cylinder is detachably connected to the bottom end of the vehicle body 11.

[0048] Specifically, the base can be the ground or the base of the equipment, for example, it can be connected to the base 21 by anchor bolts and the base 21 can be stably fixed on the ground, so that the reaction force of the hydraulic cylinder on the lifting and correction force of the vehicle body 11 can be stably transmitted to the ground, making it more stable and reliable.

[0049] In this embodiment, by setting the hydraulic lifting support 20 as a structure of hydraulic cylinder and base 21, the base 21 can stably fix the hydraulic cylinder on the base and reliably transmit the lifting force, that is, the correction force on the ring T-shaped part 02, making the structure more stable and reliable.

[0050] Optionally, such as Figure 1 and Figure 2 As shown, the hydraulic lifting support 20 also includes a pressure gauge, which is installed in the hydraulic cylinder and used to detect the pressure of the hydraulic cylinder.

[0051] Specifically, the pressure gauge can be a digital control pressure gauge and can be connected to the controller for automatic detection and display. At the same time, the controller can be electrically connected to the hydraulic cylinder to automatically adjust the extension and retraction of the hydraulic cylinder, that is, the pressure on the vehicle body and the circular T-shaped part 02 in real time, to prevent excessive pressure from damaging the components and to prevent insufficient pressure from failing to perform the correction function. In addition, an audible and visual alarm can be set to provide real-time alarm prompts for adverse conditions such as excessive pressure.

[0052] In this embodiment, by setting a pressure gauge on the hydraulic cylinder, the pressure of the hydraulic cylinder, that is, the pressure of the hydraulic lifting support 20 on the vehicle body 11, can be obtained. At the same time, it is also the calibration pressure of the ring T-shaped part 02. This can provide reliable reference data for operators or operating systems in real time, prevent the adverse effects caused by excessive or insufficient pressure, and improve the reliability and safety of operation.

[0053] In addition, such as Figure 1 As shown, another embodiment of the present invention provides a synchronous correction system for welding of a circular T-shaped part, including a controller and a synchronous correction device for welding of a circular T-shaped part as described above. The controller is electrically connected to the welding carriage 10, the hydraulic lifting support 20 and the rotating roller 40 of the synchronous correction device for welding of a circular T-shaped part.

[0054] For example, the controller can adjust the movement path and status of the welding carriage 10 in real time. For instance, the controller receives data from the weld seam tracking component 16 set on the welding carriage 10 and adjusts the path of the welding torch. It can also adjust the magnetic adsorption component 15 on the welding carriage 10, for example, by turning it on and off, to select whether it is adsorbed on the cylinder section 01. At the same time, the controller can adjust the action status of the hydraulic lifting support 20. For instance, the controller can obtain the pressure of the hydraulic cylinder of the hydraulic lifting support 20 and adjust the pressure on the ring T-shaped part 02 in real time. The controller can also adjust whether and when the rotating roller 30 rotates to achieve overall automated operation, further improve work efficiency, and reduce the labor intensity of the operators.

[0055] In this embodiment, the synchronous correction system for welding ring T-shaped parts provided herein, by setting up a controller and the aforementioned synchronous correction device for welding ring T-shaped parts, and by electrically connecting the controller to the welding carriage 10, hydraulic lifting support 20 and rotating roller 40 of the synchronous correction device for welding ring T-shaped parts, has roughly the same technical effect as the aforementioned synchronous correction device for welding ring T-shaped parts, and will not be repeated here. At the same time, the controller can automatically control and adjust the welding carriage 10, hydraulic lifting support 20 and rotating roller 30, which is conducive to realizing automated operation and further improving the quality and efficiency of welding operation.

[0056] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
