Abstract

The invention provides a hot-working back burning distortion corrector. The hot-working back burning distortion corrector comprises a dolly, air inlet tubes and acetylene inlet tubes, the dolly is fixedly provided with a control box and a support, two ends of the support are respectively provided with a mixed gas tube, the mixed gas tubes are connected with the air inlet tubes and the acetylene inlet tubes respectively, and the bottom of each of two ends of each of the mixed gas tubes is provided with a flame nozzle. The hot-working back burning distortion corrector allows the dolly to automatically push two flame nozzles at two ends of the support in order to carry out the heating distortion correction of a steel plate structure, so the hot-working back burning distortion work can be completed only through one-time running of the dolly, thereby the hot-working back burning work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a hull construction equipment, in particular to an pyrotechnic backburning straightening machine, which is used for heating and straightening the hull structure during the hull construction process. Background technique [0002] In the process of hull construction, in order to eliminate the residual stress generated during structural welding, correct corner deformation, prevent hull deformation, and facilitate installation, pyrotechnic backfire is usually performed on the reverse side of the welding angle. Pyrotechnic backfiring involves a wide range of areas, heavy workload, and high quality requirements during the entire process of hull construction, and two consecutive pyrotechnic backfiring operations are required in the same weld bead. The traditional pyrotechnic back-burning construction method is manual operation of one person and one moment, and only one flame path can be formed at a time. In a structure, four manual op...
