Abstract

The invention discloses a welding preheating device applicable to steel structures in various shapes. The device comprises a walking track, a supporting beam, a rotary positioning beam and a plurality of flame spraying guns, wherein the supporting beam is slidingly arranged on the walking track; the rotary positioning beam is arranged at the top of the supporting beam; the flame spraying guns are fixedly arranged on the rotary positioning beam; the walking track comprises a circular track and a horizontal track arranged inside the circular tack and communicated with the circular track; and the top end of the supporting beam is connected with the rotary positioning beam through a positioning rotating shaft. According to the device, the flame spraying guns used for preheating welding positions can move on the walking track; when an arc-shaped steel structure or a circular steel structure is preheated, the flame spraying guns move on the circular track and preheat the welding positions of the arc-shaped steel structure or the circular steel structure along the track orderly; when a straight steel structure is preheated, the flame spraying guns move on the horizontal track and carry out flame preheating; and the flame spraying guns can be turned over according to actual use requirements. The welding preheating device is suitable for preheating steel-structure materials in various shapes; the application range is wide; and the use is convenient.

Description

technical field [0001] The invention relates to the field of steel structure welding, in particular to a welding preheating device suitable for steel structures of various shapes. Background technique [0002] Before the steel structure is welded, in order to ensure the quality and speed of welding, the welding position will be preheated before welding. Most of the existing preheating methods use manual hand-held flame spray guns for preheating. This preheating method generally takes a long time, and the preheating temperature at the welding preheating position is uneven. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a welding preheating device suitable for steel structures of various shapes, which has a fast preheating speed and is suitable for preheating materials of various shapes of steel structures. [0004] Technical scheme of the present invention is: [0005] A welding preheating device suitable for s...
