Welding equipment for tower crane maintenance Technical Field The invention belongs to the technical field of manual arc welding, and particularly relates to welding equipment for maintaining a tower crane. Background Because the tower crane needs to bear alternating heavy load and wind load for a long time and dynamic stress generated by braking of the tower crane in the service process, key stress parts of the steel structure, particularly stress concentration areas (such as weld heat affected zones, the periphery of connecting holes and abrupt cross sections) of the tower crane are extremely easy to generate micro cracks due to material fatigue, if the micro cracks cannot be timely found and effectively treated, the micro cracks can be continuously expanded under the continuous stress effect, and finally the steel structure can be broken suddenly, so that the found micro cracks or local damages need to be welded and repaired under the regular maintenance of the tower crane, and the known weak links need to be welded and reinforced in a preventive manner, so that the safe and stable operation of the tower crane is ensured. At present, in the high-altitude welding maintenance operation of a tower crane steel structure, manual arc welding is still the most mainstream means due to simple equipment and flexible operation, however, the mode has obvious limitation in actual combat, the welding process needs to be frequently interrupted in the construction process due to the limited length of a single welding rod, a series of operations such as new welding rods, re-clamping and arc striking again are adopted, and the like, so that under the high-altitude operation environment of tens of meters and even hundreds of meters, the operation is complicated, the effective welding time occupation ratio is greatly reduced, and a welder is forced to repeatedly operate both hands on a narrow operation platform, so that the risk of high-altitude instability is greatly increased.
