Description

Cable interface protection device of ductile cast iron pipeline welding machine Technical Field The utility model relates to the technical field of pipeline welding, in particular to a cable connector protection device of a nodular cast iron pipeline welding machine. Background In the casting process of the spheroidal graphite cast iron pipeline, an impact point is formed on the end face of the cast pipeline socket by adopting a mode of forming a small hole on the socket plug sand core. In the subsequent cement internal coating process, cement is injected into the cast iron pipeline which rotates fast centrifugally, and then the cement covers the inner wall of the pipeline under the action of centrifugal force. The existence of the impact point enables the cast iron pipe to vibrate violently during centrifugal rotation, so that the generated vibration force enables cement to be better and more uniformly attached to the inner wall of the pipeline, and the subsequent quality accident caused by falling of lining cement is effectively reduced. These factors can cause the point of impact to fall off before the cement on-line process is reached, due to poor core opening, poor casting, or collisions during cast iron pipe handling. For this purpose, the missing impact points must be repaired prior to the internal coating, and the impact points manually repaired. In the use process of the field welding repair welding machine, the cable is repeatedly pulled frequently, so that the cable quick plug inserted in the cable interface is easy to loose, the plastic sheath at the tail part of the quick plug is also easy to damage, the welding machine works abnormally, and potential safety hazards are brought.
