Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting hook for a centrifugal bearing of a turbocharger. Background Art
[0002] The centrifugal bearing of the turbocharger, as shown in the attached figure of the specification Figure 1 and Figure 2 As shown in the figure, it is heavy and is a special large part. During the processing, it needs to be lifted to transfer it between different workstations. However, due to its irregular structure and an opening on one side, it cannot be centered. Therefore, when lifting, it cannot be firmly connected to the lifting rope and is very easy to fall off, causing product damage and even safety accidents. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a lifting hook for a centrifugal bearing of a turbocharger with a simple structure, low cost and high stability.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A lifting hook for a centrifugal bearing of a turbocharger comprises a lifting ring, a lifting arm and a lifting hook, wherein the lifting ring is fixedly connected to the lifting arm, a slot is provided at one end of the lifting arm away from the lifting ring, a middle portion of the lifting hook is located in the slot and is rotatably connected to the lifting arm, and a distance between the two ends of the lifting hook is greater than an opening size of the centrifugal bearing.
[0006] In this way, when lifting the centrifugal bearing, the hook is rotated close to the boom, and the boom is held and moved into the centrifugal bearing. When the hook passes through the opening of the centrifugal bearing, the hook is rotated to be perpendicular to the boom. Since the distance between the two ends of the hook is larger than the opening size of the centrifugal bearing, the hook will not be separated from the centrifugal bearing. The lifting ring is connected to the traveling crane, and the lifting ring is lifted by the traveling crane, thereby driving the centrifugal bearing to move through the boom and the hook.
[0007] Wherein, the lifting ring is connected to the lifting arm by welding.
[0008] Wherein, the hook is an arc-shaped hook, and the arc-shaped hook is conformally fitted to the inner side wall of the centrifugal bearing.
[0009] Wherein, a mounting hole is provided at the end of the lifting arm corresponding to the slot, a pin shaft is installed in the mounting hole, an opening is provided in the middle of the lifting hook, and the lifting hook is rotatably matched with the pin shaft.
[0010] Wherein, both ends of the pin shaft are located on the outside of the boom and are provided with locking holes, and a locking pin is interference-fitted in the locking hole, and the length of the locking pin is greater than the diameter of the mounting hole.
[0011] Wherein, both ends of the pin shaft are located on the outside of the boom and both ends of the pin shaft are provided with external threads, and both ends of the pin shaft are threadedly connected with locking nuts.
[0012] In summary, the lifting hook for the centrifugal bearing of the turbocharger has the advantages of simple structure, low cost and high stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0021] like Figure 1-7 As shown, a lifting hook for a centrifugal bearing of a turbocharger comprises a lifting ring 1, a lifting arm 2 and a lifting hook 3, wherein the lifting ring is fixedly connected to the lifting arm, a slot 4 is provided at one end of the lifting arm away from the lifting ring, a middle portion of the lifting hook is located in the slot and is rotatably connected to the lifting arm, and a distance between the two ends of the lifting hook is greater than an opening size of the centrifugal bearing.
[0022] In this way, when lifting the centrifugal bearing 5, the hook is rotated close to the boom, and the boom is held and moved into the centrifugal bearing. When the hook passes through the opening of the centrifugal bearing, the hook is rotated to be perpendicular to the boom. Since the distance between the two ends of the hook is larger than the size of the opening 6 of the centrifugal bearing, the hook will not be separated from the centrifugal bearing. The lifting ring is connected to the traveling crane, and the lifting ring is lifted by the traveling crane, thereby driving the centrifugal bearing to move through the boom and the hook.
[0023] The lifting hook has a simple structure and is easy to manufacture. It is made of metal material and has high strength. It can better withstand the gravity of the centrifugal bearing and lift better.
[0024] During implementation, the lifting ring is connected to the lifting arm by welding, which is convenient for manufacturing.
[0025] During implementation, the hook is an arc-shaped hook, and the arc-shaped hook is conformed to the inner wall of the centrifugal bearing, thereby increasing the contact area with the centrifugal bearing and improving the stability of lifting.
[0026] During implementation, a mounting hole is provided at the end of the arm corresponding to the notch, a pin shaft 7 is installed in the mounting hole, and an opening is provided in the middle of the hook, and the hook and the pin shaft are rotatably matched to facilitate the rotation of the hook.
[0027] During implementation, both ends of the pin shaft are located outside the boom and are provided with locking holes, in which a locking pin is interference-fitted, and the length of the locking pin is greater than the diameter of the mounting hole, so as to facilitate manufacturing.
[0028] During implementation, both ends of the pin shaft are located outside the boom and both ends of the pin shaft are provided with external threads, and both ends of the pin shaft are threadedly connected with locking nuts, which is convenient for manufacturing.
[0029] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
