Technical Field

[0001] The utility model relates to the technical field of shipbuilding equipment, in particular to a semi-automatic adsorption-type backside heater used for hull segment construction. Background Art

[0002] The construction of hull sections involves extensive welding, which can cause residual stress and deformation in the plates. This requires heating the plates on their backs with a heat gun, using a back-burning correction process to correct the deformation caused by welding. Traditionally, this process involves a single worker holding a heat gun and back-burning the plates, firing only one flame path at a time. This is not only inefficient but also results in errors in the straightness of the back-burning path and uneven heating, requiring a high level of worker experience and skill.

The top of the first longitudinal link is welded and fixed to the frame, and the first longitudinal link is connected to the middle part of the transverse link through a first adjusting connecting clamp 6. By rotating the first adjusting connecting clamp, the transverse link is moved up and down along the first longitudinal link to adjust the height of the double-burner drying gun. The two ends of the transverse link are connected to the bottom of the second longitudinal link 9 and the third longitudinal link 10 respectively through a second adjusting connecting clamp 7 and a third adjusting connecting clamp 8. The second adjusting connecting clamp causes the second longitudinal link to move left and right along the transverse link, and rotating the third adjusting connecting clamp causes the third longitudinal link to move left and right along the transverse link. The top ends of the second longitudinal link and the third longitudinal link are both rotatably connected to a double-nozzle drying gun 12 through a connecting nut 11. The double-nozzle drying gun includes a transverse tube 1201, and the two ends of the transverse tube are respectively provided with a connected vertical tube 1202.

By loosening the connecting nut, the double-burner drying gun can be rotated on the plane according to different flame channel width requirements until each burner corresponds to a flame channel. After positioning is completed, ignite the double-burner drying gun, start the drive motor, and make the burner complete the back burning correction operation along the flame channel.
