Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, and particularly relates to a special C-shaped hook for lifting sleeves. Background Art

[0002] In the cold rolling workshop of the aluminum processing industry, the finished aluminum coil sleeves or semi-finished aluminum coil sleeves produced are stacked inside the workshop. Due to their large mass, lifting tools or forklifts are often used for transportation or movement. However, due to the large number of equipment placed inside the workshop and the large production quantity, the spacing between the stacked aluminum coil sleeves is very narrow. Sometimes, there is only a space for people to pass sideways between two rows of aluminum coil sleeves, and some aluminum coil sleeves are stacked in multiple layers, resulting in the need to use only lifting tools for movement. Since most of the existing C-shaped hooks are fixed and can only be inserted horizontally into the aluminum coil sleeves from one side, but due to the small spacing, there is no condition for hanging large C-shaped hooks, resulting in frequent occurrence of equipment damage or personnel taking risks during the lifting process, and there are major safety hazards. Therefore, this technical solution is proposed for improvement. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiency that it is inconvenient to use a C-shaped hook for lifting when the spacing of aluminum coil sleeves is narrow in the prior art, and to provide a special C-shaped hook for lifting sleeves.

[0004] In order to achieve the above purpose, the embodiment of the utility model specifically adopts the following technical scheme: a special C-shaped hook for lifting sleeves, including a connecting rod, the bottom of the connecting rod is provided with a working rod for insertion through a connecting structure, the upper part of the connecting rod is provided with an auxiliary rod, the connecting structure includes a connecting cylinder arranged at the end of the working rod, a plurality of clamping grooves are arranged on the inner wall of the connecting cylinder, and a convex rib for clamping with the clamping groove is arranged at the lower part of the connecting rod.

[0005] Further, the auxiliary rod and the working rod are arranged on the same vertical plane through an adjusting device, the adjusting device is a connecting ring arranged at the end of the auxiliary rod, a plurality of mounting holes are arranged at the upper part of the connecting rod, and the connecting ring and the mounting holes are connected through pins.

[0006] Further, an installation groove for installing a wooden square is arranged on the upper surface of the working rod, and the installation groove is arranged along the length direction of the working rod.

[0007] Further, a supporting block is arranged at the bottom of the connecting rod, and the diameter of the supporting block is larger than the diameter of the connecting cylinder.

[0008] Further, a lifting ring is arranged at the top of the connecting rod, a plurality of adjusting holes are arranged on the upper surface of the auxiliary rod, and the lifting ring is screwed into the adjusting holes.

[0009] Further, a clamping ring is slidably arranged on the connecting rod below the auxiliary rod, and a locking bolt and a support plate for adjusting the position are arranged on the side wall of the clamping ring.

[0014] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0015] See Figures 1 to 2, an embodiment of the utility model discloses a novel special C-shaped hook for a lifting sleeve. It mainly consists of a connecting rod 1, a working rod 2 and an auxiliary rod 3. The bottom of the connecting rod 1 is connected to the working rod 2 through a connecting structure. This connecting structure enables the working rod 2 to be flexibly disassembled and installed and ensures the stability of the connection. Specifically, the connecting structure includes a connecting cylinder provided at the end of the working rod 2. A plurality of clamping grooves are provided on the inner wall of the connecting cylinder, and a rib 101 matching these clamping grooves is provided at the lower part of the connecting rod 1. Through the clamping of the rib 101 and the clamping grooves, a firm connection between the working rod 2 and the connecting rod 1 can be achieved. A supporting block 102 is provided at the bottom of the connecting rod 1. The diameter of the supporting block 102 is larger than that of the connecting cylinder, which can provide a larger supporting area, enhance the stability and load-bearing capacity of the C-shaped hook, and prevent the C-shaped hook from deforming or being damaged due to uneven stress during the lifting process.

[0016] An auxiliary rod 3 is provided at the upper part of the connecting rod 1 to increase the flexibility and stability of the operation. The auxiliary rod 3 is kept in the same vertical plane as the working rod 2 through an adjusting device. The adjusting device adopts the form of a connecting ring 301. The connecting ring 301 is welded and fixed at the end of the auxiliary rod 3, and a plurality of mounting holes 103 are provided at the upper part of the connecting rod 1. By selecting mounting holes 103 at different positions and connecting the connecting ring 301 to the mounting holes 103 with pins, the distance between the auxiliary rod 3 and the working rod 2 can be adjusted to adapt to aluminum coil sleeves of different sizes and thicknesses.

[0017] An installation groove 201 is provided on the upper surface of the working rod 2. This installation groove 201 is arranged along the length direction of the working rod 2 and can be used to install auxiliary materials such as wooden squares, improving the safety and convenience of the operation. During the lifting process, certain deformation occurs in the installed wooden square, which can reduce the stress between the working rod 2 and the aluminum coil sleeve, play a buffering and stabilizing role, reduce the indentation on the aluminum coil sleeve, ensure the product quality and improve the production effect.

[0018] At the top of the connecting rod 1, a lifting ring 302 is provided for connecting with the lifting equipment. On the upper surface of the auxiliary rod 3, a plurality of adjusting holes 303 are also provided, and the lifting ring 302 is screwed inside these adjusting holes 303. According to different lifting requirements, the position of the appropriate lifting ring 302 can be selected for lifting, improving the flexibility and safety of the operation.

[0019] When in use, the working rod 2 and the connecting rod 1 can be disassembled. Even inside a narrow space, when the working rod 2 can be inserted obliquely into the aluminum coil sleeve, it can be clamped with the connecting rod 1, greatly reducing the space required for hoisting. After the working rod 2 and the connecting rod 1 are stably connected, the position of the auxiliary rod 3 needs to be adjusted at this time. Also, to facilitate the adjustment of the length and angle of the C-shaped hook for more stable use, a clamping ring 4 is slidably arranged on the connecting rod 1 below the auxiliary rod 3. A locking bolt and a support plate 401 for adjusting the position are provided on the side wall of the clamping ring 4. Since the auxiliary rod 3 needs to be inserted into the connecting rod 1, it is rather laborious to lift the connecting rod 1 and the working rod 2 manually, and the use of a lifting tool will cause shaking and is inconvenient for installation. When adjusting the position of the auxiliary rod 3, the connecting rod 1 can be lifted by the lifting tool first, and then the clamping ring 4 is slid to the upper part of the aluminum coil sleeve, the locking bolt is locked, and the lifting tool is released. Since the distance between the working rod 2 below and the inside of the aluminum coil sleeve is very close, the whole will not deflect. Then the position of the auxiliary rod 3 can be freely adjusted. By adjusting the position of the clamping ring 4 and tightening the locking bolt, the length and angle of the C-shaped hook can be changed to adapt to aluminum coil sleeves of different sizes and shapes, greatly enhancing the installation efficiency inside a narrow space, ensuring the use effect, and effectively solving the problems in the transfer and movement of aluminum coil sleeves in narrow spaces in the aluminum processing industry. It can not only meet the operation requirements in narrow spaces but also improve the safety and convenience of operation.
