Shipbuilding track-free back burning machine

Abstract

The invention discloses a shipbuilding track-free back burning machine, which includes a machine body (11) equipped with permanent magnetic driving wheels (16) at the bottom, a motor and a transmission mechanism driving the driving wheels in the machine body, and roasting torches that are fixed on the machine body and utilize a pipeline to connect a fuel gas source. The shipbuilding track-free back burning machine provided in the invention can efficiently and automatically realize back burning in a ship steel structure construction process, meets the needs of ship production, improves the back burning quality and efficiency, and is more conducive to improving the building accuracy of the ship steel structure. Specifically, by setting a roasting torch longitudinal and transverse adjustment unit, the use range of the equipment provided by the invention is broadened. At the same time, two roast torches are arranged in the same equipment, and realize simultaneous work, thus improving the work efficiency. The machine provided by the invention mainly aims to meet flame distortion rectification of shipbuilding, especially in areas needing workers to look up flame distortion rectification. The machine eliminates the welding internal stress, alleviates the labor intensity of workers, improves the working efficiency of workers, and enhances the shipbuilding accuracy and appearance.

Description

technical field [0001] The present invention relates to a kind of equipment for shipbuilding, more specifically, relates to a kind of equipment for eliminating the welding internal stress of marine steel products. Background technique [0002] During the shipbuilding process, the accuracy control and the orderliness and appearance of the outer plate are very important aspects to ensure the quality of the shipbuilding and win the reputation of the shipowner, and one of the important factors affecting the precision of the shipbuilding is the welding deformation of the hull. Hull welding deformation is a common phenomenon in the shipbuilding process. After the hull is deformed, it will affect the accuracy and quality of the overall construction of the ship, and affect the appearance of the ship. The welding deformation of the hull can be reduced through pyrotechnic correction, but due to the huge workload, Most of the cutting requires workers to look up to work, and the workloa...

Hull welding deformation is a common phenomenon in the ship construction process. After the hull is deformed, it will affect the accuracy and quality of the overall ship construction, and affect the appearance of the ship. The welding deformation of the hull can be reduced through pyrotechnic correction, but due to the huge workload, Most of the cutting requires workers to look up to work, and the workload is heavy. Due to the above reasons, the work cycle of pyrotechnic correction is long, which often affects the normal progress of the next process, which may cause the extension of the construction cycle, resulting in failure to deliver the ship on schedule and affect The reputation of the enterprise; if the pyrotechnic correction is not carried out, it is very easy to cause the line type to be inconsistent with the theoretical shape, thereby changing the draft of the ship, increasing the resistance of the hull, and affecting the performance of the ship; even the stress concentration in some parts, the components are easy to fatigue, and the ship will be affected accordingly Lifespan and Safety
