Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, and in particular to an adjustable submerged arc welding horizontal welding position welding fixture device. Background Technology

[0002] The core role of medium and heavy plates in boiler steel frames: Modern ultra-large tower boiler steel frames can reach heights of over 140 meters, with component plate thicknesses generally exceeding 100 mm (some reaching 250 mm), and cross-sectional dimensions reaching 2.5 m × 2.5 m. These structures need to withstand loads exceeding 10,000 tons per column, placing extremely high demands on the strength, resistance to lamellar tearing, and stability of welded joints. The welding quality of medium and heavy plates directly affects the overall structural safety.

[0003] Significant drawbacks of traditional manual gas shielded welding: The manual CO2 gas shielded welding commonly used in workshops today (such as H08Mn2SiA welding wire) suffers from three major bottlenecks:

[0004] Low efficiency: Limited deposition rate, requiring multiple layers and multiple passes of welding, while automated processes (such as three-wire submerged arc welding) can penetrate 50-60mm steel plates in one pass;

[0005] Unstable forming quality: The weld appearance is prone to undercut and porosity, and the pass rate depends on the welder's experience (strict training in operating techniques is required).

[0006] High labor costs: A single project requires a large number of certified welders, and the labor intensity is high (protective equipment is complicated to wear, and long-term operation can easily lead to fatigue).

[0007] The urgent technological needs of industry upgrading: With the promotion of 1000MW ultra-supercritical units (such as Tianjin Beijiang Power Plant and Guangdong Taishan Power Plant projects), traditional processes are difficult to meet the requirements.

[0066] This patent provides multiple parallel solutions; the different descriptions represent improved solutions or parallel solutions based on the basic solution. Each solution has its own unique characteristics. Furthermore, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0067] Example 1: Referring to all the accompanying drawings; An adjustable submerged arc welding horizontal welding position welding fixture device, characterized in that,

[0068] The tooling device includes a base 2, on which a power part and a fixing part are arranged to support the square tube support 3.

[0069] The power unit includes a hydraulic cylinder 7 that is hinged to the base 2 via a first lug 6; the power shaft end of the hydraulic cylinder 7 is connected to the upper hinge position 11.

[0070] The upper hinge position 11 is hinged to the upper end of the square tube support 10;

[0071] The fixed part includes a square tube auxiliary support 5 which is hinged to the base 2 via a second ear plate 14. A lower fixed plate 16 is arranged at the end of the auxiliary support 5. The square tube auxiliary support is hinged to an upper auxiliary support 15, and an upper fixed plate 17 is arranged below the upper auxiliary support 15.

[0072] The lower fixed plate 16 and the upper fixed plate 17 each have a strip-shaped hole for the auxiliary support screw assembly 4 to pass through. The auxiliary support screw assembly 4 is a long strip-shaped rod structure with threads at both ends. The distance between the lower fixed plate 16 and the upper fixed plate 17 can be adjusted by the cooperation of the auxiliary support screw assembly 4 and the nut 18.

[0073] The bottom of the square tube support 3 is hinged to the base 2 via the third ear plate;

[0074] A workpiece limiting plate 1 is arranged on the square tube support 3 to limit the workpiece 12.

[0075] The substantive technical effects and implementation process of the technical solution presented herein, i.e., its basic functions, are as follows: By manufacturing this adjustable submerged arc welding horizontal welding fixture, it is mainly aimed at the penetration fillet welds in medium and thick plate T-joints, including those without bevels, single V bevels, and double V bevels. It changes the manual gas shielded welding method to the submerged arc welding method, reduces the number of welding passes, and improves welding efficiency and weld appearance quality.

[0076] This invention relates to the field of boiler steel frames, specifically an adjustable submerged arc welding horizontal welding position welding fixture. It uses an existing submerged arc welding machine in the production workshop as the basis for implementation, and combines its operating functions to create an adjustable submerged arc welding horizontal welding position welding fixture that meets welding requirements.

[0077] This fixture is adjustable via a hydraulic cylinder 7, with an adjustable angle range of 25°-50°. It can be used for welding full penetration fillet welds in T-joints of medium and thick plates, including those without beveling, single V-beveling, and double V-beveling. One fixture is placed every 2.5 meters, and multiple fixtures are fabricated and evenly distributed according to the component length. This can accommodate welding components approximately 3.5 meters wide. In field use, based on the component's beveling shape, the fixture angle is first adjusted synchronously. When the component is positioned, the beveling is kept in the correct position. After adjusting the position and angle, the auxiliary support mechanism is tightened using a screw assembly, and then welding is performed using a submerged arc welding carriage. When used in conjunction with a submerged arc welding machine, this fixture reduces the number of welding passes compared to manual gas shielded welding, improves welding efficiency and weld appearance quality, frees up manpower, and reduces labor costs.

[0078] This tooling can be used in the butt welding of various medium and thick plates and is widely used in boiler steel frame products. It fully meets the welding process requirements, can significantly reduce labor costs, improve product quality, and has good economic value.

[0079] Example 2: As a further improvement, parallel, or optional independent solution, the first ear plate 6, the second ear plate 14, the third ear plate, the corresponding square tube support 3, and the corresponding base 2 comprise multiple sets; the multiple sets of square tube supports 3 are welded together by crossbars to form the bottom support of the workpiece 12. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the first ear plate 6, the second ear plate 14, and the third ear plate all appear in pairs and are used as the basis for hinges.

[0080] Example 3: As a further improvement, parallel, or optional independent solution, both the lower fixed plate 16 and the upper fixed plate 17 are square. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: facilitating alignment.

[0081] Example 4: As a further improvement, parallel, or optional independent solution, the strip holes of the lower fixed plate 16 and the upper fixed plate 17 are aligned with each other. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the strip holes provide a basic shape to assist in the positional movement of the lead screw assembly 4.

[0082] Example 5: As a further improvement, parallel, or optional independent solution, it also includes a hydraulic station 13 capable of providing power to the hydraulic cylinder 7.

[0083] Example 6: As a further improvement, parallel, or optional independent solution, the auxiliary support screw assembly 4 comprises multiple sets. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the number of sets can be flexibly adjusted according to the size of the tool to be welded.

[0084] Example 7: As a further improvement, parallel, or optional independent solution, multiple sets of bases 2 are arranged one every 2.5 meters. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: this distance can also be flexibly adjusted.

[0085] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0086] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.

[0087] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.
