AI Technical Summary
The lack of hook containment mechanisms in existing cargo ship cranes leads to severe hook swaying caused by pitching and rolling due to wind and waves during operations at sea, increasing the risk of hook detachment and posing a danger of impacting the ship or injuring personnel.
A cargo ship crane with a hook receiving mechanism was designed. The column is driven to rotate and the slide rail assembly is moved by a hydraulic turntable to adjust the lifting direction and distance. The hook is received in the receiving box by an electric telescopic rod and connecting plate to avoid large swings.
It improves the stability of the hook, extends its service life, enhances the safety of cargo lifting, and avoids severe swaying of the hook in wind and waves.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo ship cranes, and in particular to a cargo ship crane with a hook receiving mechanism. Background Technology
[0002] Bulk carriers are short for bulk cargo ships, which are specifically designed to transport unpackaged goods such as coal, ore, timber, livestock, and grain. The cranes on bulk carriers are devices and machinery that are built into the ship for loading and unloading cargo. Currently, the cranes on bulk carriers rely on the main boom and hook to move objects from one place to another. Since the main boom cannot be extended or retracted, it is always necessary to rotate the main boom to move objects with the hook, which is very cumbersome to operate.
[0003] Chinese patent CN219689160U discloses a bulk carrier crane. This technical solution uses an extended moving component and a slider. The slider is driven by a drive device to slide along the mounting plate and the extension plate, thereby moving the cargo between the bulk carrier and the dock. The cargo is no longer moved by rotating the boom, thus avoiding the problem of the centrifugal force caused by rotation causing the hook and cargo to sway.
[0004] However, the crane on this cargo ship does not have a hook retrieval mechanism during use. This means that when the ship is in operation at sea, the pitching and rolling caused by wind and waves will cause the hook to shake violently, increasing the risk of it falling off due to inertia or external impact, causing it to collide with the ship, fall into the sea, or injure people. This is not conducive to the use of the cargo ship crane.
[0005] Therefore, it is necessary to provide a cargo ship crane with a hook receiving mechanism to solve the above-mentioned technical problems. Utility Model Content
[0006] This utility model provides a cargo ship crane with a hook receiving mechanism, which solves the problem that the cargo ship crane does not have a hook receiving mechanism during use, which causes the hook to shake violently when the ship rolls and pitches due to wind and waves during operation at sea.
[0007] To solve the above-mentioned technical problems, the present invention provides a cargo ship crane with a hook receiving mechanism, including a hydraulic turntable. The output shaft of the hydraulic turntable is detachably connected to a column. A horizontal beam is fixedly connected to the top of the side wall of the column. A winding assembly that moves along the length direction is provided at the bottom of the horizontal beam via a slide rail assembly. A hook body is provided at the lifting end of the winding assembly. A receiving box is fixedly connected to the bottom of the winding assembly. A connecting plate that moves vertically is provided at the bottom of the inner cavity of the receiving box. An electric telescopic rod is provided at the front and rear ends of one side of the connecting plate. The other end of the electric telescopic rod is fixedly connected to the receiving box. The receiving box extends movably to the outside of the receiving box and is adapted to the hook body.
[0008] Preferably, the output shaft of the hydraulic turntable is fixedly connected to a turntable, and the turntable is detachably connected to the bottom end of the column by bolts.
[0009] Preferably, a number of reinforcing ribs are fixedly connected between the upper surface of the turntable and the side wall of the column.
[0010] Preferably, the bottom of the hydraulic turntable is fixedly connected to a base, the top of the column sidewall is fixedly connected to a connecting part, and the crossbeam is detachably connected to the connecting part.
[0011] Preferably, a fixed box is vertically fixedly connected to the bottom of the inner wall of the receiving box, a motor is fixedly connected to the bottom of the inner wall of the fixed box, a bolt rod is vertically fixedly connected to the output shaft of the motor, a threaded sleeve is threadedly connected to the surface of the bolt rod, a connecting block is fixedly connected to the side wall of the threaded sleeve, and the other end of the connecting block extends movably to the outside of the fixed box and is fixedly connected to the side wall of the connecting plate.
[0012] Preferably, the side wall of the fixing box has a vertical opening for the connecting block to move.
[0013] Preferably, the side wall of the receiving box has an opening for the receiving box to extend and retract, and the side wall of the receiving box has a guide opening for the electric telescopic rod to move vertically.
[0014] Compared with related technologies, the cargo ship crane with hook receiving mechanism provided by this utility model has the following beneficial effects:
[0015] This utility model provides a cargo ship crane with a hook receiving mechanism. After the column is driven to rotate by a hydraulic turntable, the lifting direction can be adjusted. After the slide rail assembly is in operation, it can move along the length of the crossbeam, thereby adjusting the lifting distance, which is beneficial for cargo lifting operations. After the lifting is completed, the electric telescopic rod can be extended to move the receiving box to the outside of the receiving box. Then, after the connecting plate moves vertically, the receiving box can be moved upward through the connection of the electric telescopic rod. After the opening is fitted onto the outside of the hook body, the hook body can be received and protected, which can prevent the hook body from swinging and shaking significantly, improve the stability of the hook body, extend the service life of the hook body, and improve the safety of cargo lifting.
