Description

Technical Field

[0001] The invention relates to the technical field of frame welding mechanisms, in particular to an adjustable welding mechanism for a prefabricated box girder reinforcement frame. Background Art

[0002] Prefabricated box beam is a type of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part. It is named after its resemblance to a box. It is generally made of a steel frame. When producing and preparing prefabricated box beams with steel bars, welding is generally used to complete the production and processing of prefabricated box beams with steel frame.

[0003] The existing Chinese patent application with application publication number CN116810269A discloses a welding and manufacturing device for a steel structure frame of a building decorative curtain wall, including a manufacturing device main body, the manufacturing device main body including a workbench, two first slide grooves and a welding module are arranged on the top of the workbench, the welding module is located on the rear side of the two first slide grooves, a steel structure frame platform is movably arranged on the top of the workbench, an adjustment mechanism is movably arranged in the first slide groove, the upper end of the adjustment mechanism is connected to the steel structure frame platform, and is used to adjust the rotation of the steel structure frame platform; in this invention, an operator can rotate the steel structure frame platform by operating the adjustment mechanism, and can rotate the angle of the steel bar on the welding frame platform, and then the operator can use the welding module to weld the steel bar parts below, thereby improving the welding efficiency.

[0004] However, this welding mechanism has the following defects when used specifically:

[0005] 1. When the existing welding mechanism uses a laser generator to weld the steel skeleton, the laser welding operation will cause the temperature of the welding position to rise. When the welding points are then tested to detect the quality of laser welding, the residual laser welding temperature will affect the accuracy of the test results. At the same time, when the laser welding of the weld points of the steel skeleton is completed and the cooling operation of the weld points is completed for a long time, the welded steel skeleton is prone to fracture or even deformation due to long-term high temperature. The quality and toughness of the laser welded steel skeleton are poor, and it is difficult to meet the strength requirements of bridge deck construction and installation;

[0006] 2. When the existing welding mechanism performs laser welding on the corresponding steel frame prefabricated box beam, due to the different locations of the steel frame installation inside the different prefabricated box beams, when multiple laser generators are used to weld the steel frame, the position of each group of laser generators is difficult to adjust synchronously.
