[0002] Marine cranes are lifting equipment specifically designed for ships, used for loading and unloading cargo, adjusting equipment, or performing other related tasks. Existing marine cranes are prone to swaying during cargo lifting, which can pose a safety hazard.

[0003] To overcome the aforementioned deficiencies, a prior art Chinese patent (publication number: CN221876384U) discloses an anti-sway device for a marine crane hook, comprising: a crossbeam, a buffer assembly disposed at the bottom of the crossbeam, an anti-sway assembly disposed at the bottom of the buffer assembly, and a hook assembly disposed at the bottom of the anti-sway assembly; the anti-sway assembly includes: a pulley rotatably disposed at the bottom of the buffer assembly, movable plates slidably disposed inside both sides of the crossbeam, and a steel cable disposed between the two sets of movable plates; the crossbeam is also provided with a tensioning assembly, which includes: a thrust member slidably disposed inside both sides of the crossbeam, and a connecting column movably disposed between the thrust member and the buffer assembly; the thrust member is connected to the movable plate. When the hook drives the pulley to bounce up and down for cushioning, the steel cable can stably tighten the bouncing pulley, improving the stability of the hook's suspended parts and preventing the steel cable from falling off due to pulley swaying.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation: during the use of marine cranes, both the lifting cable and the hook will swing, so it is necessary to fix the lifting cable and the hook. Utility Model Content

[0005] The purpose of this utility model is to provide a marine electro-hydraulic crane with an anti-sway stabilizing structure to solve the problem in the background art where the lifting cable and hook of the marine crane will swing during use, thus requiring the lifting cable and hook to be fixed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine electric hydraulic crane with an anti-sway stabilizing structure, comprising a telescopic boom and a rotating mounting block, wherein two symmetrically distributed connecting blocks are fixedly connected to the top of the rotating mounting block, and the two connecting blocks are rotatably connected to both sides of the upper end of the telescopic boom;

[0007] Both ends of the rotating mounting block are fixedly connected to sliding sleeves, and both sliding sleeves are fixedly connected to stabilizing sliding rods. A limit block is fixedly connected to the top of the stabilizing sliding rod, and a stabilizing plate is fixedly connected to the lower end of the stabilizing sliding rod. The two stabilizing sliding rods, sliding sleeves and stabilizing plate form a rectangular stabilizing structure.

[0009] Preferably, each of the stabilizing slide rods has a positioning groove on its inner side, and a telescopic rod is fixedly connected to the inner side of the slide sleeve. The telescopic end of the telescopic rod is fixedly connected to a limiting rod, which extends into the interior of the slide sleeve and is engaged with the positioning groove.

[0010] Preferably, the limiting rod extends into the interior of the sliding sleeve and is engaged with the interior of the positioning groove, and two limiting rods are symmetrically distributed on the inner sides of the two sliding sleeves.

[0011] Preferably, a rotating seat is installed at the lower end of the telescopic arm, and the rotating seat is connected to the hull. A hoisting cable is provided at the top of the telescopic arm, and the hoisting cable extends to the middle of the rotating mounting block.

[0012] Preferably, the rotating mounting block is provided with a stabilizing sleeve, and the hoisting cable is slidably connected inside the stabilizing sleeve, and the hoisting cable extends downward through the stabilizing sleeve to the middle of the stabilizing plate.

[0013] Preferably, the hoisting structure includes a hoisting block, and the hoisting block and the hoisting cable ends are connected to each other. Four movable plates are fixedly connected to the top outer side of the hoisting block, and the X-shaped structure formed by the four movable plates fits into the bottom of the stabilizing plate.

At this time, the rectangular structure formed by the rotating mounting block, the stabilizing slide rod and the stabilizing plate will limit the swing amplitude of the movable plate, thereby limiting the swing amplitude of the hook at the bottom of the lifting block, thus improving the stability of the hook lifting the cargo.

[0017] Furthermore, the extension of the lifting cable at the end of the telescopic boom will be located between the stabilizing sleeve and the stabilizing plate, thereby stabilizing the lifting cable, preventing it from becoming unstable during the lifting process, and improving the stability of the lifted goods.

[0018] Furthermore, the stabilizing plate is guided to move by the positioning plates on both sides of the movable plate until the stabilizing plate and the movable plate are in contact with each other. At this time, the limiting rod is connected to the inside of the positioning groove, thereby fixing the rectangular structure formed by the rotating mounting block, the stabilizing slide rod and the stabilizing plate, thus reducing the swing amplitude of the movable plate and the hook.

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a marine electric hydraulic crane with an anti-sway stabilizing structure, comprising a telescopic boom 1 and a rotating mounting block 2. Two symmetrically distributed connecting blocks 3 are fixedly connected to the top of the rotating mounting block 2, and the two connecting blocks 3 are rotatably connected to the upper sides of the telescopic boom 1. Sliding sleeves 4 are fixedly connected to both ends of the rotating mounting block 2, and stabilizing sliding rods 5 are fixedly connected inside each of the two sliding sleeves 4. A limit block is fixedly connected to the top of each stabilizing sliding rod 5, and a stabilizing plate 10 is fixedly connected to the lower end of each stabilizing sliding rod 5. The two stabilizing sliding rods 5, the sliding sleeves 4, and the stabilizing plate 10 form a rectangular stabilizing structure. The bottom of the stabilizing plate 10 is provided with a hoisting structure for hanging objects. Positioning grooves 6 are provided on the inner sides of each stabilizing sliding rod 5. A telescopic rod 7 is fixedly connected to the inner side of the sleeve 4, and a limiting rod 8 is fixedly connected to the telescopic end of the telescopic rod 7. The limiting rod 8 extends into the interior of the sleeve 4 and is engaged with the interior of the positioning groove 6. The limiting rod 8 has two symmetrically distributed on the inner sides of the two sleeves 4. A rotating seat 11 is installed at the lower end of the telescopic arm 1 and is connected to the hull. A hoisting cable 12 is provided at the top of the telescopic arm 1 and extends to the middle of the rotating mounting block 2. The rotating mounting block 2 is provided with a stabilizing sleeve 9, and the hoisting cable 12 is slidably connected to the interior of the stabilizing sleeve 9. The hoisting cable 12 passes through the stabilizing sleeve 9 and extends downward to the middle of the stabilizing plate 10.

[0028] During the crane hoisting process, the goods are hoisted by the hook 16. At this time, the retraction of the hoisting cable 12 drives the hook 16 to move upward. The movable plate 14 will then come into contact with the stabilizing plate 10. Simultaneously, the telescopic rod 7 drives the limiting rod 8 and the positioning groove 6 inside the stabilizing slide rod 5 to engage with each other, thereby fixing the position of the stabilizing slide rod 5 inside the sliding sleeve 4. At this time, the rectangular structure formed by the rotating mounting block 2, the stabilizing slide rod 5 and the stabilizing plate 10 will limit the swing amplitude of the movable plate 14, thereby limiting the swing amplitude of the hook 16 at the bottom of the hoisting block 13, thus improving the stability of the hook 16 in hoisting the goods.

[0029] During the extension and retraction of the lifting cable 12, the lifting cable 12 will slide inside the stabilizing sleeve 9. After passing through the stabilizing sleeve 9, the lifting cable 12 will connect with the lifting block 13 through the opening in the middle of the stabilizing plate 10. When the rectangular structure formed by the rotating mounting block 2, the stabilizing slide rod 5 and the stabilizing plate 10 is in a fixed state, the extension of the lifting cable 12 at the end of the telescopic arm 1 will be located between the stabilizing sleeve 9 and the stabilizing plate 10, thereby stabilizing the lifting cable 12 and preventing it from becoming unstable during the lifting process, thus improving the stability of the lifted goods.

[0030] Example 2: Based on Example 1, a hoisting structure is also disclosed, the specific structure of which is as follows: The hoisting structure includes a hoisting block 13, and the ends of the hoisting block 13 and the hoisting cable 12 are connected to each other. Four movable plates 14 are fixedly connected to the top of the outer side of the hoisting block 13, and the X-shaped structure formed by the four movable plates 14 is in close contact with the bottom of the stabilizing plate 10. The two sides of the movable plates 14 are fixedly connected to symmetrically distributed positioning plates 15, and the two positioning plates 15 are vertically distributed. The bottom of the hoisting block 13 is fixedly connected to a hook 16.

[0031] During the lifting process of hook 16, the limiting rod 8 is first driven by telescopic rod 7 to fix the position of stabilizing slide rod 5 inside sliding sleeve 4. At this time, lifting cable 12 will extend through the middle of stabilizing plate 10. Lifting cable 12 will drive lifting block 13 and movable plate 14 to separate from stabilizing plate 10, thereby making the movement of hook 16 unrestricted. When hook 16 lifts goods, it is convenient for manual operation. After hook 16 is connected to goods, the limiting rod 8 and positioning groove 6 are separated. Stabilizing plate 10 will move downward and be guided by positioning plates 15 on both sides of movable plate 14 until stabilizing plate 10 and movable plate 14 are in contact. At this time, the limiting rod 8 and positioning groove 6 are connected to each other, thereby fixing the rectangular structure formed by rotating mounting block 2, stabilizing slide rod 5 and stabilizing plate 10, thereby reducing the swing amplitude of movable plate 14 and hook 16.
