[0002] As an important mechanical equipment widely used in the fields of building construction, mining, shipbuilding, etc., the core component of the hoist is the drum assembly. The running stability of the drum assembly directly affects the overall work efficiency and service life of the hoist. However, under the existing technical conditions, there are still obvious technical shortcomings in the static balance correction of the drum assembly, especially for medium and large drums.
[0003] The static balance tool commonly used in the current market is usually designed simply and has limited coverage, which cannot adapt to drum assemblies of multiple specifications and models. For example, the adjustability of the tool is poor, and it is difficult to meet the static balance detection needs of medium and large drums. Especially for drum assemblies with a length of more than 1 meter and a large diameter change, the existing detection method cannot provide accurate and fast correction means.
[0004] During the production and processing of the drum assembly, it is inevitable to produce imbalance due to uneven material, processing errors and other factors. This imbalance is manifested as eccentricity of the drum during whole machine running test, which not only leads to increased running vibration, but also may exacerbate mechanical wear and tear, shorten the service life of the equipment. More seriously, these imbalance problems will also affect the safety of the hoist and increase the risk of operation.
[0005] In view of the imbalance problem of the drum, the existing tooling and detection equipment generally lack flexibility and applicability, and it is difficult to meet the static balance correction needs of enterprises for drum assemblies of different lengths and diameters. In addition, the traditional correction method relies on experience and manual adjustment, which has the problems of insufficient precision and low efficiency. This deficiency leads to low first-time pass rate of product assembly, greatly increases the disassembly and repair workload, and seriously affects the production efficiency and cost control of enterprises.
[0006] With the improvement of industrial automation and intelligence level, the market demand for high-precision and high-reliability hoist equipment is increasing. Therefore, a technical solution that can efficiently and accurately detect and correct the static balance of the drum assembly has become an urgent need in the industry. INVENTION CONTENTS
