Description

Beam crane defect vision inspection cradle head Technical Field The invention belongs to the field of crane detection equipment, and particularly relates to a beam crane defect vision inspection cradle head. Background In high-risk scenes such as industrial production, building construction and the like, the crane bears the effects of heavy load, vibration and complex environment for a long time, and the problems such as metal structure fatigue, part wear and electrical system aging can be gradually accumulated. If not detected in time, the minor defects may be changed into serious accidents, such as hook breakage, wire rope breakage, braking failure and even complete machine overturning, which directly threatens the life and property safety of personnel. Therefore, when the crane is used, a plurality of indexes such as the metal supporting structure, the lifting mechanism and the running state are required to be detected regularly. When main bearing components such as a main beam, an end beam, a supporting leg and a frame are inspected for cracks, deformation and corrosion, and when the running conditions of parts and mechanisms such as treads, rims, abrasion and rail gnawing of a trolley traveling wheel are inspected, inspection personnel are generally required to climb to an inspection passage of an inspection cage or the main beam to inspect the structure and the running conditions of a crane in a manual visual inspection mode, but the running conditions of a lower area of the main beam, the side of the supporting leg, an electric hoist and a running mechanism cannot be directly observed and judged through close-range visual inspection, and particularly large-scale lifting equipment is easier to have larger detection dead zones, so that the detection difficulty is increased, the detection efficiency is reduced, the personal safety of inspection personnel is difficult to ensure, and the accuracy and the comprehensiveness of detection results are also reduced.
