Technical Field
[0001] The utility model belongs to the technical field of special equipment detection, and particularly relates to a hook detection auxiliary device suitable for a lifting site. Background Art
[0002] A hook is the most common type of sling in a hoisting machine. Since it often hangs heavy objects and is prone to wear, it is also a vulnerable component. A hook should be scrapped under any of the following circumstances: 1. Cracks; 2. The wear of the dangerous end face reaches 10% of the original size; 3. The opening degree increases by 15% compared with the original size; 4. The torsional deformation of the hook body exceeds 10°; 5. Plastic deformation occurs in the dangerous section of the hook or the hook neck; 6. The hook thread is corroded; 7. When the wear of the bushing of the laminated hook reaches 50% of the original size, the bushing should be replaced; 8. When the wear of the arbor of the laminated hook reaches 5% of the original size, the arbor should be replaced. Among them, when problems occur with the hook thread, bushing and arbor of the laminated hook, they can basically be directly observed with the naked eye, while cracks, wear, opening degree, torsional and plastic deformation of the hook cannot be directly observed with the naked eye. This requires the use of detection equipment to detect it.
[0003] In the prior art, for the detection of hooks, a three-dimensional deformation detection system is usually adopted. The hook is scanned by a CCD camera installed on a bracket, and the detection of the hook is realized through a three-dimensional software analysis platform and a hook scrapping analysis system. Although this method can realize the detection of the hook. However, for the use site of the hook (during the use of the hook, it is necessary to regularly check the cracks, deformation, wear, corrosion, etc. of the hook), because the hook is not convenient to disassemble, at this time, it is necessary for workers to hold a three-dimensional scanner and scan around the hook, which is time-consuming and laborious. Moreover, because the hook is in a free state, when it is affected by wind or external environmental disturbances, the hook will swing, which poses a great safety hazard to the workers and will also affect the scanning effect, and the practicability is poor.
