Description

Technical Field

[0001] The invention belongs to the technical field of cranes, in particular to a crane capable of stabilizing a ship. Background Art

[0002] Cranes are multi-action lifting machinery that can lift heavy objects vertically and move them horizontally within a certain range. They can efficiently complete the lifting and moving tasks of various heavy goods, greatly improving work efficiency and safety. In some cases, ships need to be transferred from one water area to another (such as from an inland river to the ocean), and cranes are needed to lift the ships from the water and load them onto transport ships for transshipment.

[0003] Patent publication number CN218778622U discloses a ship repair crane, belonging to the field of ship repair technology. The crane comprises an inverted U-shaped support frame and a servo motor mounted on one side of the U-shaped support frame. A steel wire rope extends directly below the horizontal plate of the U-shaped support frame. A rope splitter is fixed around the lower portion of the wire rope, and multiple auxiliary hooks are positioned around the rope splitter. A first hydraulic pump is positioned on the underside of the four vertical plates of the U-shaped support frame, and a support plate is positioned on the underside of the first hydraulic pump. The support plate is connected to the first hydraulic pump via a first hydraulic rod. A second hydraulic pump is positioned oppositely below the horizontal plate of the U-shaped support frame, and L-shaped clamping plates are positioned on opposite sides of the two second hydraulic pumps. Compared to existing technologies, this ship repair crane offers improved stability during repairs and a wider range of applications. It can not only lift and secure ships, but also lift and repair ship components, and then clamp and secure the lifted ship components.

Although the ship can be lifted in this way, in some cases, the components connecting the ship and the hook may be relatively fragile. For example, the components are damaged or aged due to external forces, and the components will be subjected to stress during lifting. Therefore, the components may break, causing the ship to fall, which not only affects the smooth progress of the lifting work, but also easily hits the surrounding personnel, posing a certain safety hazard.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The crane capable of stabilizing a ship of the present invention utilizes a bow and stern sheathed lifting mechanism to sheath the bow and stern of the ship through a second steel wire rope, and then winds up the first steel wire rope to lift the ship from the water. Since the first steel wire rope is in contact with the main body of the ship and is not a component on the ship, it avoids the situation in which the component connected to the hook is relatively fragile and the ship falls during lifting, thereby ensuring the smooth progress of the lifting work and, at the same time, avoiding the falling of the ship to the surrounding personnel, thereby having good safety. Moreover, after the ship is sheathed by the second steel wire rope, the box is driven The body is rotated 180 degrees so that the steel wire rope 2 is in a cross state on the upper side of the part outside the box body, and then the steel wire rope 2 is reeled in. During the reeling process of the steel wire rope 2, the ship will gradually approach the intersection on the upper side of the steel wire rope 2, thereby reducing the redundant space between the ship and the steel wire rope 2. The steel wire rope 2 and the ship can be further fitted together, avoiding the situation that after the bow and stern of the ship are wrapped by the steel wire rope 2, there is a certain redundant space between the ship and the steel wire rope 2, and the ship is easy to slip off the steel wire rope 2 due to the shaking of the steel wire rope 2 during the lifting process, further ensuring the stability of the ship during the lifting process.

[0022] 2. A crane capable of stabilizing a ship according to the present invention utilizes a water-intake auxiliary mechanism. Before the second steel wire rope enters the water, the two groove plates simultaneously approach each other and contact the second steel wire rope, so that the second steel wire rope is embedded in the groove of the groove plate, and the pressure strip presses the second steel wire rope into the groove of the groove plate. Then, the second steel wire rope and the groove plate are driven into the water at the same time. The second steel wire rope in the water will remain stable due to the limitation of the groove plate and the pressure of the pressure strip, and will not sway. When the second steel wire rope wraps around the bow and the stern of the ship, the two groove plates are driven away from each other, and the pressure strip no longer presses the second steel wire rope, and the second steel wire rope can be used to stabilize the ship. Normal lifting can be performed, thereby preventing the steel wire rope No. 2 from swaying in the water due to the high water flow rate when the steel wire rope No. 2 enters the water, resulting in the steel wire rope No. 2 being unable to accurately wrap around the ship, thereby affecting normal lifting; utilizing the groove removal component, when the groove plate is away from the steel wire rope No. 2, the protrusions No. 1 and No. 2 can simultaneously push the steel wire rope No. 2 in the groove of the groove plate from multiple directions, promoting its separation from the groove plate, thereby preventing the steel wire rope No. 2 from being stuck in the groove plate due to impurities in the water, and when the groove plate is away from the steel wire rope No. 2, the steel wire rope No. 2 cannot separate from the groove plate, but moves with the groove plate, affecting the situation where the steel wire rope No. 2 is used to lift the ship normally.

[0036] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please refer to Figures 1-11 The present invention provides a technical solution: a crane capable of stabilizing a ship, comprising a base 30, a crane body 1 being provided on the base 30, and a bow and stern sleeve-type lifting mechanism being provided at one end of the crane body 1;

[0038] The bow and stern sleeve-type lifting mechanism includes a frame 2 installed at one end of the crane body 1, and an adjusting plate 3 is slidably connected to both sides of the frame 2. Rollers 7 are rotatably provided on both sides of the lower end of the adjusting plate 3, and a wire rope 6 is wound around the roller 7. The lower end of the wire rope 6 is fixedly connected to a connecting plate 10, and a box 11 is rotatably provided in the middle of the lower end surface of the connecting plate 10. Rollers 17 are rotatably provided on both sides of the inner cavity of the box 11, and the same wire rope 14 is wound around the two rollers 17.

[0039] In this embodiment, Figures 1-4 、 Figure 6 As shown, two ends of one side of the frame 2 are rotatably provided with bidirectional threaded rods 4, both sides of the bidirectional threaded rod 4 are threadedly connected to the adjustment plate 3, one end of the frame 2 is fixedly connected to a motor 5, and the output end of the motor 5 is fixedly connected to one end of the bidirectional threaded rod 4.

[0040] One side of the lower end of the adjustment plate 3 is fixedly connected to a motor 2 8 , and the output end of the motor 2 8 is fixedly connected to the winding roller 1 7 .

[0041] One side of the upper end surface of the connecting plate 10 is fixedly connected to the motor three 9, and the output end of the motor three 9 is fixedly connected to one side of the upper end of the box body 11.

[0042] Two motors 12 are fixedly connected to one side of the outer wall of the box body 11, and the output end of the motor 12 is fixedly connected to the roller 2 17.

[0043] Specifically, in the prior art, when a ship needs to be hoisted, a hook is fixed to a component of the ship, and then the ship is lifted using a wire rope. Although this method can achieve the hoisting of the ship, in some cases, the component connecting the ship and the hook may be relatively fragile. For example, the component may be damaged by external forces or aged. When the component is hoisted, the component will be subjected to stress, so the component may break, causing the ship to fall, which not only affects the smooth progress of the hoisting work, but also easily hits nearby workers, posing a certain safety hazard.

[0044] Therefore, in order to solve the above problems, in this embodiment, when in use, the base 30 is placed in a suitable position, and the angle and orientation of the frame 2 are adjusted by using the orientation adjustment mechanism on the crane body 1. This is a prior art and will not be described in detail.

[0045] Then, the motor 28 drives the reel 17 to rotate and unwind the wire rope 16, and the connecting plate 10 descends until the U-shaped range formed by the two wire ropes 14 is aligned with the bow and stern of the ship respectively, and the wire ropes 14 enter the water. Then, the motor 15 drives the bidirectional threaded rod 4 to rotate, so that the two adjusting plates 3 approach each other until the bow and stern of the ship are trapped by the two wire ropes 14. At this time, the wire rope 16 is rewound to lift the ship from the water. Since the wire rope 16 is in contact with the main body of the ship rather than a component on the ship, the situation that the component connected to the hook is relatively fragile and the ship falls during lifting is avoided, thereby ensuring the smooth progress of the lifting work and preventing the surrounding staff from being hit by the falling ship, which is safe.

[0046] Furthermore, since the portion of the second steel rope 14 outside the box 11 is U-shaped when the ship is lifted, there will be a certain amount of redundant space between the ship and the second steel rope 14 after the bow and stern of the ship are covered with the second steel rope 14. During the lifting process, if the second steel rope 14 shakes, the ship may slip off the second steel rope 14, which will also affect the normal lifting. Therefore, in order to avoid this situation, after the ship is covered with the second steel rope 14, the motor 3 9 drives the box 11 to rotate 180 degrees, so that the upper side of the portion of the second steel rope 14 outside the box 11 is in a cross state, and then the second steel rope 14 is used to lift the ship. The motor 4 12 drives the winding roller 2 17 to rotate and reel in the wire rope 2 14. During the reeling process of the wire rope 2 14, the ship will gradually approach the intersection on the upper side of the wire rope 2 14, thereby reducing the redundant space between the ship and the wire rope 2 14. The wire rope 2 14 can be further fitted to the ship, avoiding the situation where the bow and stern of the ship are covered by the wire rope 2 14 and the ship is easily slipped off the wire rope 2 14 due to the shaking of the wire rope 2 14 during the lifting process due to a certain redundant space between the ship and the wire rope 2 14. This further ensures the stability of the ship during the lifting process.

[0047] In this embodiment, Figure 4-11 As shown, the box body 11 is also provided with a water inlet auxiliary mechanism that can keep the wire rope 2 14 stable in the water;

[0048] The water inlet auxiliary mechanism includes an adjustment block 18 slidably connected to both sides of the upper end surface of the box body 11. A groove plate 13 is rotatably provided at one end of the adjustment block 18. The groove plate 13 is semi-U-shaped, and the wire rope 14 can be embedded in the groove of the groove plate 13.

[0049] One side of the adjustment block 18 is threadedly connected to a threaded rod 15, and both ends of the threaded rod 15 are rotatably set on the box body 11. One side of the upper end surface of the box body 11 is fixedly connected to a motor 5 16, and the output ends on both sides of the motor 5 16 are fixedly connected to one end of the threaded rod 15. One side of the adjustment block 18 is fixedly connected to a motor 6 19, and the output end of the motor 6 19 is fixedly connected to the upper end of the groove plate 13.

[0050] A plurality of pressure strips 25 are rotatably provided on one side of the groove plate 13 , and a plurality of motors 24 are fixedly connected to one side of the groove plate 13 , and the output end of the motor 24 is fixedly connected to one end of the pressure strip 25 .

[0051] The groove plate 13 is provided with a groove removal component;

[0052] The degrooving assembly includes a second protrusion 23 and two first protrusions 21 slidably connected to the groove plate 13. A guide column 29 is fixedly connected to one side of the protrusion 23. A sliding rod 28 is fixedly connected to one side of the upper end of the groove plate 13. The sliding rod 28 is slidably connected to the transmission rod 22. A sliding groove 20 is provided at the lower end of the transmission rod 22. The guide column 29 passes through the sliding groove 20 and is slidably connected to it. The protrusion 1 21 is fixedly connected to the transmission rod 22.

[0053] One side of the upper end of the transmission rod 22 is threadedly connected to a threaded rod 27, one end of the threaded rod 27 is rotatably set on the groove plate 13, one side of the upper end of the groove plate 13 is fixedly connected to a motor 8 26, and the output end of the motor 8 26 is fixedly connected to one end of the threaded rod 27.

[0054] Specifically, in the above embodiment, although the ship can be hoisted by wrapping the second steel wire rope 14 around the bow and stern of the ship, the second steel wire rope 14 needs to enter the water to contact the bottom of the ship. When the water flow rate is high, the second steel wire rope 14 will sway in the water, resulting in the second steel wire rope 14 being unable to accurately wrap around the ship, affecting normal hoisting. Therefore, in order to avoid this situation, the working principle of this embodiment is as follows:

[0055] Before the steel wire rope 2 14 enters the water, the threaded rods 15 on both sides rotate at the same time under the action of the motor 5 16, and the two groove plates 13 approach each other at the same time and contact the steel wire rope 2 14, so that the steel wire rope 2 14 is embedded in the groove of the groove plate 13, and then multiple motors 7 24 are started at the same time and drive the pressure bar 25 to rotate, and the pressure bar 25 presses the steel wire rope 2 14 tightly in the groove of the groove plate 13, and then drives the steel wire rope 2 14 and the groove plate 13 into the water at the same time, and the motor 7 24 is provided with a waterproof shell, and will not malfunction due to entering the water; at this time, the steel wire rope 2 14 in the water will be limited by the groove plate 13 and the pressure of the pressure bar 25 The second rope 14 is tightly held and remains stable without swaying. When the second rope 14 is wrapped around the bow and stern of the ship, the two groove plates 13 are driven away from each other, and the pressure strip 25 no longer presses the second rope 14, and the ship can be normally hoisted using the second rope 14. This avoids the situation where the second rope 14 sways in the water due to the high water flow rate when the second rope 14 enters the water, resulting in the inability of the second rope 14 to accurately wrap around the ship, thereby affecting the normal hoisting. In addition, before the box body 11 rotates, the motor 6 19 can be used to drive the groove plate 13 to rotate 90 degrees, so that the groove plate 13 and the box body 11 are in a parallel state, so that the groove plate 13 does not interfere with the rotation of the box body 11.

[0056] Although the groove plate 13 can be used to limit the steel wire rope 2 14 to prevent it from swaying in the water, in order to ensure the stability of the steel wire rope 2 14 in the water, the steel wire rope 2 14 is embedded in the groove of the groove plate 13. There are impurities such as aquatic plants in the water. These impurities are easily moved to the groove of the groove plate 13 with the water flow, resulting in the steel wire rope 2 14 being stuck in the groove plate 13. When the groove plate 13 is away from the steel wire rope 2 14, the steel wire rope 2 14 cannot be separated from the groove plate 13, but moves with the groove plate 13, thereby affecting the normal lifting of the ship by the steel wire rope 2 14. Therefore, in order to avoid this situation, when the groove plate 13 is away from the steel wire rope 2 When the wire rope 2 is 14, the motor 8 26 drives the threaded rod 27 to rotate, so that the transmission rod 22 drives the protrusion 1 21 to move, and the transmission rod 22 drives the guide column 29 and the protrusion 2 23 to move through the slide groove 20, so that the protrusion 1 21 and the protrusion 2 23 can simultaneously push the wire rope 2 14 in the groove of the groove plate 13 from multiple directions, promoting its separation from the groove plate 13, thereby avoiding the wire rope 2 14 from being stuck in the groove plate 13 due to impurities in the water. When the groove plate 13 is away from the wire rope 2 14, the wire rope 2 14 cannot separate from the groove plate 13, but moves with the groove plate 13, affecting the normal lifting of the ship by the wire rope 2 14.

[0057] Working principle: Place the base 30 in a suitable position, and use the azimuth adjustment mechanism on the crane body 1 to adjust the angle and azimuth of the frame 2. This is a prior art and will not be described in detail. Then, the motor 2 8 drives the reel 1 7 to rotate, unwinding the wire rope 1 6. The connecting plate 10 then descends until the U-shaped range formed by the two wire ropes 14 is aligned with the bow and stern of the ship, and the wire ropes 14 enter the water. Then, the motor 1 5 drives the bidirectional threaded rod 4 to rotate, so that the two adjustment plates 3 approach each other until the bow and stern of the ship are trapped by the two wire ropes 14. At this time, the wire rope 1 6 is reeled in to lift the ship from the water. Since the steel wire rope 16 is in contact with the main body of the ship rather than a component on the ship, it avoids the situation in which the component connecting the ship and the hook is relatively fragile and the ship falls during lifting, thereby ensuring the smooth progress of the lifting work. At the same time, it also avoids the surrounding workers being hit by the falling of the ship, which is safe. Moreover, since the part of the steel wire rope 2 14 outside the box 11 is U-shaped when lifting the ship, there will be a certain amount of redundant space between the ship and the steel wire rope 2 14 after the bow and stern of the ship are covered with the steel wire rope 2 14. During the lifting process, if the steel wire rope 2 14 shakes, the ship may slip off the steel wire rope 2 14, which will also affect the normal lifting. Therefore, in order to avoid this situation, when the ship is covered with the wire rope 2 14, the motor 3 9 drives the box 11 to rotate 180 degrees, so that the wire rope 2 14 is in a cross state on the upper side of the outer part of the box 11, and then the motor 4 12 is used to drive the reel 2 17 to rotate to reel the wire rope 2 14. During the reeling process of the wire rope 2 14, the ship will gradually approach the intersection of the upper side of the wire rope 2 14, thereby reducing the redundant space between the ship and the wire rope 2 14, and the wire rope 2 14 can be further fitted to the ship, avoiding the situation that after the bow and stern of the ship are covered with the wire rope 2 14, there is a certain redundant space between the ship and the wire rope 2 14, and the ship can be lifted during the hoisting process. The situation that the wire rope 2 14 is easy to slip off from the wire rope 2 14 due to the shaking of the wire rope 2 further ensures the stability of the ship lifting process. Before the wire rope 2 14 enters the water, the threaded rods 1 15 on both sides rotate at the same time under the action of the motor 5 16, and the two groove plates 13 approach each other and contact the wire rope 2 14 at the same time, so that the wire rope 2 14 is embedded in the groove of the groove plate 13. Then, multiple motors 7 24 are started at the same time and drive the pressure bar 25 to rotate. The pressure bar 25 presses the wire rope 2 14 tightly in the groove of the groove plate 13, and then drives the wire rope 2 14 and the groove plate 13 into the water at the same time. In addition, the motor 7 24 is provided with a waterproof shell, which will not malfunction due to entering the water;At this time, the steel wire rope 14 in the water will remain stable due to the limitation of the groove plate 13 and the compression of the pressure strip 25, and will not sway. When the steel wire rope 14 is wrapped around the bow and the stern, the two groove plates 13 are driven away from each other, and the pressure strip 25 no longer compresses the steel wire rope 14, and the ship can be normally hoisted using the steel wire rope 14, thereby avoiding the situation that when the steel wire rope 14 enters the water, the steel wire rope 14 sways in the water due to the high water flow rate, resulting in the steel wire rope 14 being unable to accurately wrap around the ship. , thus affecting the normal lifting situation, and before the box body 11 rotates, the motor 6 19 can drive the groove plate 13 to rotate 90 degrees, so that the groove plate 13 and the box body 11 are in a parallel state, so that the groove plate 13 will not interfere with the rotation of the box body 11; although the groove plate 13 can limit the wire rope 2 14 to prevent it from swaying in the water, in order to ensure the stability of the wire rope 2 14 in the water, the wire rope 2 14 is embedded in the groove of the groove plate 13, and there are impurities such as aquatic plants in the water, which Some impurities are easy to move to the groove of the groove plate 13 with the water flow, thereby causing the wire rope 2 14 to be stuck in the groove plate 13. When the groove plate 13 is away from the wire rope 2 14, the wire rope 2 14 cannot be separated from the groove plate 13, but moves with the groove plate 13, thereby affecting the normal lifting of the ship by the wire rope 2 14. Therefore, in order to avoid this situation, when the groove plate 13 is away from the wire rope 2 14, the motor 8 26 drives the threaded rod 2 27 to rotate, so that the transmission rod 22 drives the protrusion 1 21 to move, and the transmission rod 2 The guide post 29 and the second protrusion 23 are driven to move by the chute 20, so that the first and second protrusions 21 and 23 can simultaneously push the second wire rope 14 in the groove of the groove plate 13 from multiple directions, promoting its separation from the groove plate 13. This prevents the second wire rope 14 from being stuck in the groove plate 13 due to impurities in the water. When the groove plate 13 moves away from the second wire rope 14, the second wire rope 14 cannot separate from the groove plate 13 and moves with the groove plate 13, affecting the normal lifting of the ship by the second wire rope 14.
