Welding equipment for civil air defense door

Abstract

The invention discloses welding equipment for a civil air defense door. The welding equipment comprises a main equipment body, an outer frame and a welding arm, wherein a second-stage rotating shaft is arranged on the right side of a first-stage rotating shaft and movably connected with the first-stage rotating shaft, a third-stage rotating shaft is arranged at the bottom of the welding arm and innested connection with the welding arm, and an ultrasonic detection head is arranged in the middle of a detection board and in nested connection with the detection board. The ultrasonic detection head can detect welding state automatically, the welding equipment is controlled automatically to perform welding again when pseudo soldering, tack weld and rack of fusion is detected, working efficiencyof the equipment is improved greatly, and welding reject ratio is reduced; detail direction of the welding equipment can be regulated by the third-stage rotating shaft, and welding precision is improved, so that the equipment has the advantages of high flexibility and multi-angle welding, is applicable to the welding equipment for the civil air defense door and has extensive application prospectin future.

Description

technical field [0001] The invention relates to the technical field of civil air defense, in particular to welding equipment for civil air defense doors. Background technique [0002] Civil air defense refers to the measures and actions taken to mobilize and organize the people to prevent enemy air attacks and eliminate the consequences of air strikes, referred to as civil air defense. Civil air defense, homeland air defense and field air defense together form a national air defense system, which is an important part of modern national defense. Its purpose is to protect the safety of people's lives and property, reduce national economic losses, and preserve war potential. [0003] But the existing civil air defense door, the welding angle is very small due to the particularity of the civil air defense door, and the existing welding equipment is very easy to cause virtual welding, false welding, and unreliable welding when welding, which has the advantages of High safety haz...
