[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-2 , Figure 1A schematic diagram of the overall structure of an embodiment of the disc-shaped gear lifting device provided by this utility model; Figure 2 A schematic diagram of the hook structure of one embodiment of the disc-shaped gear lifting device provided by this utility model.

[0023] In one specific embodiment, the disc-shaped gear lifting device includes a lifting ring 10, hooks 30, and an annular transition connector 20. The lifting ring 10 is connected to the annular transition connector 20. The tops of the three hooks 30 are movably connected to the annular transition connector 20. A first arc 31 and a second arc 32 that bend inward are sequentially provided between the top and bottom of the hooks 30, so that the bottom ends of the three hooks 30 bend inward relative to the top to form a support space. The bottom ends of the three hooks 30 are used to support the gear 40 to be transported.

[0024] By using an annular transition connector 20 to movably connect three hooks 30, and by sequentially bending the first arc 31 and the second arc 32 inward between the top and bottom of the hooks 30, a support space is formed to support the gear 40 to be transported. The user can apply force through the lifting ring 10 and rotate different sizes through the movable connection, which solves the problem of transporting small parts. The tooling is simple in shape and easy to manufacture, and the lifting device is simple and convenient to make, with great on-site adjustability.

[0025] To further improve the support efficiency for components and reduce damage to gears and other components during the support process, in one embodiment, the disc-shaped gear lifting device further includes a support platform disposed at the bottom of the hook 30, the lateral dimension of which increases with the increase of the distance from the hook 30.

[0026] By setting up support platforms, the parts are prevented from flipping up and down. At the same time, the original contact between the curved surface and the parts is changed to a contact between two planes, increasing the contact area. In addition, the three support platforms form a plane parallel to the plane of the parts, making the lifting device more stable when lifting the parts.

[0027] This application does not limit the shape, size, or installation method of the support platform. The support platform can be a triangular support platform, a trapezoidal support platform, or a support platform of other shapes. The bottom of the hook 30 is welded to or snapped onto the support platform, or connected in other ways. Users can replace the support platform with different shapes and sizes according to their needs.

[0028] The function of the first arc 31 in this application is to ensure that important parts of the gear parts do not come into contact with the hook 30, thereby preventing collisions with the parts and improving the safety of hoisting. During hoisting, padding is generally added to prevent collisions. When hoisting at high temperatures, gypsum wool (made of alumina) is added, mainly to prevent collisions during hoisting. The second arc 32 is mainly determined by the outer diameter of the part. The larger the outer diameter, the smaller the angle. It is also affected by the total length of the hook 30. The longer the hook 30 is, the larger the arc angle is when the part remains unchanged.

[0029] This application does not impose any limitations on the angles of the first arc 31 and the second arc 32.

[0030] In one embodiment, the first arc 31 and the second arc 32 are in the same plane, the first arc 31 is an arc with a central angle of 70°-90°, and the second arc 32 is an arc with a central angle of 135°-180°.

[0031] By setting the first arc 31 and the second arc 32 in the same plane, they are subjected to forces in the vertical direction as much as possible during the lifting process, without any circumferential forces. This prevents twisting and other issues from occurring during the lifting process, ensuring safety and reliability during the lifting operation.

[0032] In this application, the curvature radius of the first arc 31 and the second arc 32 are not limited. They can be designed according to actual needs, such as according to the size of different objects to be lifted. The corresponding angles should not be limited to the angles mentioned above. In addition to the two arcs mentioned above, more arcs can be added as needed.

[0033] In this application, the hook 30 is movably connected to the annular transition connector 20. The connection method is not specifically limited. The top of the hook 30 is sleeved or hinged to the annular transition connector 20, or connected in other ways.

[0034] This application does not limit the structure of the annular transition connector 20, which can be a circular annular transition connector 20 or an elliptical annular transition connector 20.

[0035] This application does not limit the size, material, etc. of the multiple hooks 30. Preferably, the multiple hooks 30 are of equal length and have the same shape.

[0036] Because the top hooks 30 may slip during use, the bottom support may become unstable.

[0037] To address the aforementioned technical issues, in one embodiment, the disc-shaped gear lifting device further includes a separating component that is sleeved or snapped onto the annular transition connector 20, for separating adjacent hooks 30.

[0038] By using a separating component to sleeve or snap onto the annular transition connector 20, adjacent hooks 30 are separated, allowing the top of the corresponding hook 30 to be limited, preventing displacement and improving efficiency and stability in subsequent use.

[0039] This application does not impose any limitations on the structure, size, material, or fixing method of the partition components.

[0040] The lifting ring 10 in this application is connected to the annular transition connector 20 so that personnel or equipment can be lifted and subjected to force. The connection method between the two is not limited. In one embodiment, the lifting ring 10 is welded or snapped to the annular transition connector 20.

[0041] In one embodiment, the disc-shaped gear lifting device includes a ring, a lifting ring 10, and three hooks 30 within the ring. All components are made of Q345 steel. The first arc 31 of the hook 30 is related to the part being lifted and can be adjusted on-site according to the actual size of the part. The second arc 32 is related to the part being lifted and the spacing between the upper and lower parts, and can also be adjusted according to the actual needs on site. A horizontal bar is welded to the bottom of the hook 30 to increase the contact area with the part and maintain lifting balance.

[0042] Two of the three hooks 30 inside the lifting ring 10 are on one side, and the other is on the other side. There is no fixing device between the three hooks 30. This is to make it convenient to put away and put away the lifting equipment when it is not in use. When lifting different parts, the three hooks 30 can be quickly bent into the corresponding shapes.

[0043] The crossbar in front of the hook 30 is used to prevent the parts from flipping up and down. At the same time, it changes the original contact between the curved surface and the parts to a flat-to-flat contact, increasing the contact area. In addition, the three crossbars form a plane parallel to the plane of the parts, making the lifting device more stable when lifting the parts.

[0044] The first arc 31 of the hook 30 is used to ensure that important parts of the gear parts do not come into contact with the hook 30, and to prevent collisions with the parts. During hoisting, padding is generally added to prevent collisions. When hoisting at high temperatures, gypsum wool (made of aluminum oxide) is added, mainly to prevent collisions during hoisting.

[0045] The angle of the first arc 31 is mainly determined by the height of the part. The taller the part, the larger the arc. The optimal angle range is between 70° and 90°. The angle of the second arc 32 is mainly determined by the outer diameter of the part. The larger the outer diameter, the smaller the angle. The optimal angle range is between 135° and 180°. At the same time, the second arc 32 is also affected by the total length of the hook 30. The longer the hook 30 is, the larger the arc angle will be if the length of the part remains the same.

[0046] The length of the boom extending into the part within the irregular shape is also subject to special considerations. Due to the distance between the two parts during mounting, if the distance between the parts is too small, the length of the boom extending into the part cannot be too large, otherwise it will be difficult to insert the boom into the part, which is not conducive to operation.

[0047] The above-mentioned tooling has the following beneficial effects:

[0048] The problem of transporting small parts has been solved. The tooling is simple in shape and easy to manufacture. The size of the first arc 31 and the second arc 32 can be adjusted according to the actual site conditions. One set of tooling can achieve multiple purposes. The lifting device is simple and convenient to manufacture and has great on-site adjustability. The horizontal bar welded under the hook 30 increases the contact area and maintains the stability of the parts.

[0049] In summary, the disc-shaped gear lifting device provided in this embodiment of the utility model uses an annular transition connector to movably connect three hooks, and forms a support space for supporting the gear to be transported by sequentially bending the first and second arcs inward between the top and bottom of the hooks. Users can apply force through the lifting rings and rotate different sizes through the movable connection, solving the problem of transporting small parts. The tooling is simple in shape and easy to manufacture, and the lifting device is simple and convenient to make, with great on-site adjustability.
