The arranged rear wire feeding machine head trolley can form a condition of linkage with the automatic welding trolley, but is not a complete linkage condition and has a certain hysteresis, and due to the arrangement of the joint bearing, the wire feeding machine head trolley is allowed to slightly lag behind the automatic welding trolley, so that the wire feeding machine head trolley can not immediately follow and retreat when the wire feeding machine head trolley advances for a certain distance and needs to retreat, the phenomenon that a welding wire fed out from a welding wire coil on the wire feeding machine head trolley is suddenly turned to feed the welding wire is avoided, the condition that the welding wire is bent and broken is reduced, and the wire feeding machine head trolley is turned to a very soft direction when the automatic welding trolley turns from forward to retreat or from retreat to forward, so that the welding wire is protected.

The main configuration is as follows: 30 by 30 angle steel, 30 by 5 band iron self-control frame, join in marriage 4 sets of vertical support roller train (steel is self-made), 4 sets of horizontal spacing guide rollers (steel is self-made) and supports.

The utility model has the advantages and the beneficial effects that: in the process that the wire feeder head moves (advances frequently and retreats frequently), the advance or retreat of the wire feeder head trolley cannot be influenced by the fact that a welding wire coil of the wire feeder head trolley touches a line on a field, the wire near the wire feeder head trolley does not need to be adjusted by a worker in the process of moving along with the automatic welding trolley, otherwise, the line on the field can influence the advance or retreat of the wire feeder head trolley, and if the welding wire coil retreats frequently and touches the line on the field during the movement of the wire feeder head trolley, the wire on the field (comprising an electric wire of the automatic welding trolley and other lines such as an electric wire of the wire feeder head trolley) can be avoided easily due to the fact that the welding wire coil can rotate by a heavy hammer line. The wire feeding machine head trolley can form a condition of linkage with the automatic welding trolley, but is not completely linked, and has a certain hysteresis, and due to the arrangement of the joint bearing, the wire feeding machine head trolley is allowed to slightly lag behind the automatic welding trolley, so that the wire feeding machine head trolley can not follow the backward movement immediately when the wire feeding machine head trolley moves forward for a certain distance and needs to move backward, the welding wire fed out by a welding wire coil on the wire feeding machine head trolley is prevented from being suddenly turned to feed the wire, the condition that the welding wire is bent and broken is reduced, and the wire feeding machine head trolley is turned to a gentle direction when the automatic welding trolley is turned from forward to backward or from backward to forward, so that the welding wire is protected. The whole body is very light and easy to store and move. Meanwhile, the limiting guide rollers are arranged, so that the trolley can be ensured to move forward along with the pressing strips, and potential safety hazards caused by deviation can be avoided; the application of this dolly enables to weld the worker and concentrates on welding quality control, has alleviateed the intensity of labour that welder removed the aircraft nose, has improved automatic efficiency, the quality of welding to a certain extent, has avoided welder's the safety risk of carrying the heavy object in the narrow region in high altitude simultaneously.
