Abstract
Description
[Technical field]
[0001] The utility model belongs to the technical field of metallurgical equipment, and specifically relates to the hoisting and handling of small and medium-sized pieces in the metallurgical industry, in particular to a three-claw hook device. [Background technology]
[0002] There are various lifting tools on the market, such as lifting clamps, suspension arms, three-hook bending plates, etc. Although they all play an important role, they are not suitable for the lifting and transportation of small and medium-sized parts. Most of them are circulated by transfer vehicles. Especially for the precision-machined bearing seats, if the lifting clamps are used, it is easy to leave scratches during the transportation process, which is absolutely not allowed in the product quality requirements. For example, some lifting clamps, although they can be used for the transfer and lifting of most workpieces, they cannot be used in assembly, cannot achieve 360° rotation, and cannot protect the workpiece to the greatest extent. [Contents of the utility model]
[0003] The utility model aims to provide a three-claw hook device, which is convenient for transporting workpieces and has a more optimized structure.
[0004] To achieve the above-mentioned purpose, the utility model provides a three-claw hook device, wherein the three-claw hook device includes a support shaft, a bearing arranged on the outer periphery of the support shaft, three extension rods arranged on the bearing at intervals in the circumferential direction, and hooks respectively arranged at the ends of the three extension rods, and the three extension rods can respectively drive the three hooks to rotate 360 degrees around the support shaft.
[0005] As a further improvement of an embodiment of the utility model, the extension amount of the extension rod can be freely adjusted.
[0006] As a further improvement of an implementation mode of the utility model, a protective cover is provided on the hook.
[0007] As a further improvement of an embodiment of the utility model, the protective cover is configured as a rubber protective cover.
[0008] As a further improvement of an embodiment of the utility model, the three-claw hook device also includes an elastic gasket and a locking nut arranged on the support shaft, and in the axial direction of the support shaft, the elastic gasket is located between the bearing and the locking nut.
[0009] As a further improvement of an embodiment of the utility model, a locking structure is further provided at the end of the extension rod adjacent to the bearing, and the locking structure can be operated so that the opening angle of the extension rod can be adjusted.
[0010] As a further improvement of an embodiment of the utility model, the locking structure includes a locking rotating sleeve and a locking buckle.
[0011] As a further improvement of an embodiment of the utility model, the three-claw hook device also includes a hanging ring arranged above the support shaft.
[0012] As a further improvement of an embodiment of the utility model, three extension rods are evenly spaced and arranged on the bearing.
[0013] Compared with the prior art, in the present invention, the extension rod can drive the hook to rotate 360°, so that the three-claw hook device is convenient for transporting workpieces and has a more optimized structure.
[0014] The extension of the extension rod can be freely adjusted. This allows workpieces of different sizes to be transported, which has a wider range of applications. A protective cover is provided on the hook to protect the workpiece to the maximum extent under any working conditions and ensure the surface forming quality of the workpiece.
[0015] Equipped with spring washers for force buffering, the workpiece transfer process is more stable.
[0016] A locking structure is installed at the end of the extension rod. During use, the angle can be pre-adjusted and then locked with a locking buckle. This allows the goods to be directly lifted and transferred without the need for measurement and adjustment during use, which greatly saves time and also improves the safety factor.
[0017] In addition, the angle is adjusted in advance and clamped once when in use, which saves time and avoids the possibility of accidents during the measurement process.
[0018] Furthermore, in terms of economy, it greatly reduces economic costs and can be widely used in production and manufacturing.
