Description

Technical Field

[0001] The invention belongs to the technical field of lifting equipment, and in particular relates to a flexible sling intelligent hook. Background Art

[0002] As a key component of lifting equipment, hooks are widely used in logistics, manufacturing, construction and other fields. Traditional hooks rely on manual labor to hang and take off heavy objects, which is not only labor-intensive, but also prone to safety accidents due to improper operation, and it is difficult to meet the modern demand for efficient and safe operations. In recent years, automated hooks have attracted market attention because they can improve work efficiency and reduce the risk of human error. However, existing automated hooks still have obvious shortcomings: the complex structure leads to high manufacturing costs and difficult maintenance, and the stability is poor under high loads or sudden load changes, which affects long-term reliable operation. Therefore, there is an urgent need to design an automatic hook with a simplified structure, stable operation, and adaptability to complex working conditions to solve the current technical problems facing the industry. Summary of the Invention

[0003] The present invention aims to provide a new type of intelligent hook that realizes the automatic hanging and unhanging function of the flexible sling by simplifying the structure, reducing manual operation, improving operation efficiency and ensuring work safety, in order to solve the problem that the traditional crane hook needs to be manually hung and unhanged during operation, resulting in low work efficiency, high cost and difficulty in ensuring worker safety, and the automatic hook cannot completely solve the problem of automatic hanging and unhanging of the flexible sling.

[0004] The present invention is a flexible sling intelligent hook, which is mainly designed into two parts of four major sections: a transmission mechanism, a slewing mechanism, a driving mechanism, and an external shell and a support. The transmission mechanism is used to realize the lifting and lowering of the hook, and comprises a hook shaft (18). The hook shaft (18) is sleeved with a hook (21), a worm gear (25), a shaft sleeve (24), and a deep groove ball bearing (19) with a sealing ring on one side. Both ends of the hook shaft (18) are matched with the deep groove ball bearing (19) with a sealing ring on one side. The deep groove ball bearing (19) with a sealing ring on one side is fixed to the box through a bearing cover (23). The hook (21) is fixed on the worm gear (25). The turbine (25) is meshed with the worm (26). The DC motor (17) drives the worm (26) to rotate and then drives the hook (21) to rotate. The slewing mechanism is used to realize the horizontal rotation of the entire hook, including a slewing shaft (3), on which a slewing gear (12), a thrust ball bearing (5), a rope ring (1), and a hexagonal nut (2) are installed. The upper end of the slewing shaft (3) is fixed by the hexagonal nut (2). The slewing gear (12) is meshed with the slewing pinion (11). The slewing pinion (11) is connected to the slewing servo (9) through the metal steering plate (10). The servo drives the slewing pinion to drive the slewing shaft to rotate. The driving mechanism includes a DC motor (17), a battery (7), and a slewing servo (9). The DC motor (17) and the slewing servo (9) are fixed to the lower part of the battery motor plate (8), and the battery (7) is installed on the upper part of the battery motor plate (8). The outer shell is composed of a side plate 1 (30), a side plate 2 (33), a top plate (4), an upper rear plate (31), an upper front plate (34) and a lower sealing plate (32), and the shell support is composed of two support columns (16), one end of the support column is fixed to the side plate 1 (30), and the other end is fixed to the side plate 2 (33).

[0005] The present invention has the following beneficial effects: the present invention uses a neodymium magnet (22) to attract magnetic material on the flexible sling, and cooperates with a transmission mechanism to complete the automatic hooking of the flexible sling by the intelligent hook, thereby solving the problem that the hook is difficult to hook the sling. At the same time, an anti-unhooking device (20) is installed on the lower sealing plate, which solves the problem of unhooking that may occur during the lifting operation and ensures the safety of the lifting operation.

[0006] The present invention arranges the start button (29), the close button (28) and the three indicator lights on the same side and arranges the side panel 1 (30) to be transparent, so that the user can clearly observe the state of the hook during the operation of the hook, effectively avoiding damage to the equipment due to misoperation.

[0007] The hook shaft in the present invention has multiple functions: first, it positions many parts such as bearings and worm gears; second, it bears the lifting capacity of the smart hook and the weight of the hook, and its strength is a decisive indicator of the performance of the smart hook.

[0008] The present invention designs a bolt mounting hole on the small gear that is connected to the metal steering wheel of the servo, and designs a through hole on the large gear that is connected to the rotating shaft. At the same time, in order to ensure the rotation effect of the intelligent hook, a rotating shaft is designed. The upper part of the rotating shaft is connected to the hexagonal nut, and the lower part is fixedly connected to the large gear of the intelligent hook rotating mechanism.
