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 refer to multi-action lifting machinery that can vertically lift and horizontally move heavy objects 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 inland rivers to the ocean), and cranes are needed to lift the ships from the water and load them onto transport ships for transshipment.

[0016] The beneficial effects of the present invention are as follows: 1. The crane capable of stabilizing a ship described in 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, the situation in which 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, at the same time, avoiding the surrounding staff from being hit by the falling of the ship, and having good safety. Moreover, after the ship is sheathed with the second steel wire rope, the box is driven to The box body is rotated 180 degrees to make the upper part of the wire rope 2 outside the box body in a crossed state, and then the wire rope 2 is reeled in. During the reeling process of the wire rope 2, the ship will gradually approach the crossing part on the upper side of the wire rope 2, thereby reducing the redundant space between the ship and the wire rope 2. The wire rope 2 and the ship can be further fitted together, avoiding the situation that after the bow and stern of the ship are set by the wire rope 2, there is a certain redundant space between the ship and the wire rope 2, and the ship is easy to slip off the wire rope 2 due to the shaking of the wire rope 2 during the lifting process, which further ensures the stability of the ship during the lifting process.

[0017] 2. A crane capable of stabilizing a ship described in 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 in 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 pressing 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, so that 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 the normal lifting; utilizing the groove release assembly, 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 to promote 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; 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 normal lifting of the steel wire rope No. 2 to the ship.

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a crane capable of stabilizing a ship, comprising a base 30, a crane body 1 is arranged on the base 30, and a bow and stern sleeve-type lifting mechanism is arranged at one end of the crane body 1; The bow and stern sleeve-type lifting mechanism includes a frame 2 installed at one end of a crane body 1, and adjusting plates 3 are slidably connected on 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 steel wire rope 6 is wound around the roller 7. A connecting plate 10 is fixedly connected to the lower end of the steel wire rope 6. A box 11 is rotatably provided on the middle part of the lower end surface of the connecting plate 10, and rollers 17 are rotatably provided on both sides of the inner cavity of the box 11, and the same steel wire rope 14 is wound around the two rollers 17.

[0023] In this embodiment, Figure 1-Figure 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.

[0024] A motor 2 8 is fixedly connected to one side of the lower end of the adjustment plate 3 , and an output end of the motor 2 8 is fixedly connected to a winding roller 1 7 .

[0025] A motor 3 9 is fixedly connected to one side of the upper end surface of the connecting plate 10 , and an output end of the motor 3 9 is fixedly connected to one side of the upper end of the box body 11 .

[0026] 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.

[0027] Specifically, in the prior art, when a ship needs to be hoisted, the hook is fixed to the ship's components, and then the ship is lifted by a wire rope. Although the ship can be hoisted in this way, in some cases, the components connected to the hook may be relatively fragile. For example, the components are damaged or aged due to external forces, and the components are stressed during hoisting. Therefore, the components may break, causing the ship to fall, which not only affects the smooth progress of the hoisting work, but also easily hits the surrounding staff, posing certain safety hazards. Therefore, in order to solve the above problems, when using the present embodiment, 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 the prior art and will not be described in detail. Then, the motor 28 drives the reel 17 to rotate, unwinds the wire rope 16, and the connecting plate 10 descends until the U-shaped range formed by the two wire ropes 14 is respectively aligned with the bow and stern of the ship, and the wire ropes 14 enter the water. Then, the motor 15 drives the bidirectional threaded rod 4 to rotate, so that the two adjustment plates 3 are close to each other, until the bow and stern of the ship are covered by the two wire ropes 14. At this time, the wire rope 16 is reeled in, and the ship can be lifted from the water. Since the wire rope 16 is in contact with the main body of the ship instead of 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. At the same time, it also avoids the surrounding staff being hit by the falling of the ship, and the safety is good; Furthermore, since the portion of the steel wire 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 steel wire rope 14 after the bow and stern of the ship are covered with the steel wire rope 14. During the lifting process, if the steel wire rope 14 shakes, the ship may slip off the steel wire rope 14, which will also affect the normal lifting. Therefore, in order to avoid this situation, after the ship is covered with the steel wire rope 14, the motor 3 9 drives the box 11 to rotate 180 degrees, so that the upper side of the portion of the steel wire rope 14 outside the box 11 is in a crossed state, and then the steel wire rope 14 is used to lift the ship. The motor 4 12 is used to drive 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 and the ship can be further fitted, avoiding the situation that after the bow and stern of the ship are covered by the wire rope 2 14, the ship is easy to slip off the wire rope 2 14 due to the shaking of the wire rope 2 14 during the lifting process because there is a certain redundant space between the ship and the wire rope 2 14, further ensuring the stability of the ship during the lifting process.

[0028] In this embodiment, Figure 4-Figure 11 As shown, the box 11 is also provided with a water inlet auxiliary mechanism that can keep the steel wire rope 14 stable in the water; 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.

[0029] A threaded rod 15 is threadedly connected to one side of the adjustment block 18, and both ends of the threaded rod 15 are rotatably set on the box body 11. A motor 5 16 is fixedly connected to one side of the upper end surface of the box body 11, and the output ends on both sides of the motor 5 16 are fixedly connected to one end of the threaded rod 15. A motor 6 19 is fixedly connected to one side of the adjustment block 18, and the output end of the motor 6 19 is fixedly connected to the upper end of the groove plate 13.

[0030] 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 an output end of the motor 24 is fixedly connected to one end of the pressure strip 25 .

[0031] The groove plate 13 is provided with a groove removal component; The stripping assembly includes a second protrusion 23 and two first protrusions 21 which are 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 thereto. The protrusion 21 is fixedly connected to the transmission rod 22.

[0032] One side of the upper end of the transmission rod 22 is threadedly connected with 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 with a motor 8 26, and the output end of the motor 8 26 is fixedly connected to one end of the threaded rod 27.

[0033] Specifically, in the above embodiment, although the ship can be hoisted by means of the steel wire rope 14 being set around the bow and stern of the ship, the steel wire rope 14 needs to enter the water to contact the bottom of the ship. When the water flow rate is large, the steel wire rope 14 will sway in the water, so that the steel wire rope 14 cannot accurately set the ship, affecting the normal hoisting. Therefore, in order to avoid this situation, the working principle of this embodiment is as follows: 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 strip 25 to rotate, and the pressure strip 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, so it 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 strip 25 The steel wire rope 14 is tight and remains stable without swaying. 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, so that the steel wire rope 14 can be used to lift the ship normally, 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 flow rate of the water, resulting in the steel wire rope 14 being unable to accurately wrap around the ship, thereby affecting the normal lifting. In addition, 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 be used to limit the steel wire rope 14 to prevent it from swaying in the water, in order to ensure the stability of the steel wire rope 14 in the water, the steel wire rope 14 is embedded in the groove of the groove plate 13, and there are impurities such as aquatic plants in the water. These impurities are easy to move to the groove of the groove plate 13 with the water flow, thereby causing the steel wire rope 14 to be stuck in the groove plate 13. When the groove plate 13 is away from the steel wire rope 14, the steel wire rope 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 14. Therefore, in order to avoid this situation, when the groove plate 13 is away from the steel wire rope 14, the steel wire rope 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 14. When the wire rope 14 is moved, 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 23 to move through the slide groove 20, so that the protrusion 1 21 and the protrusion 23 can simultaneously push the wire rope 14 in the groove of the groove plate 13 from multiple directions, promote it to be separated from the groove plate 13, and thus avoid the wire rope 14 being stuck in the groove plate 13 due to impurities in the water. When the groove plate 13 is away from the wire rope 14, the wire rope 14 cannot be separated from the groove plate 13, but moves with the groove plate 13, affecting the normal lifting of the ship by the wire rope 14.

[0034] Working principle: put 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 the prior art and will not be described in detail. Then, the motor 28 drives the reel 7 to rotate, unwinds the wire rope 6, and the connecting plate 10 drops 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 rope 14 enters the water. Then, the motor 15 drives the bidirectional threaded rod 4 to rotate, so that the two adjustment plates 3 are close to each other, until the bow and stern of the ship are covered by the two wire ropes 14. At this time, the wire rope 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 where 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 and avoiding the surrounding workers being hit by the falling of the ship, thereby improving safety. In addition, 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 set by 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, after the ship is covered with the steel wire rope 14, the motor 3 9 drives the box 11 to rotate 180 degrees, so that the steel wire rope 14 is in a cross state on the upper side of the part outside the box 11, and then the motor 4 12 is used to drive the reel 2 17 to rotate to reel the steel wire rope 14. During the reeling process of the steel wire rope 14, the ship will gradually approach the intersection of the upper side of the steel wire rope 14, thereby reducing the redundant space between the ship and the steel wire rope 14, and the steel wire rope 14 can be further fitted to the ship, avoiding the bow and stern of the ship being covered with the steel wire rope 14. Because there is a certain redundant space between the ship and the steel wire rope 14, during the lifting process, the ship can The situation that the steel wire rope 2 14 is easy to slip off due to the shaking of the steel wire rope 2 14 further ensures the stability of the ship hoisting process. Before the steel wire rope 2 14 enters the water, the threaded rods 15 on both sides are rotated at the same time under the action of the motor 5 16, and the two groove plates 13 are close to each other and contact the steel wire rope 2 14 at the same time, 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 strip 25 to rotate, and the pressure strip 25 presses the steel wire rope 2 14 in the groove of the groove plate 13, and then drives the steel wire rope 2 14 and the groove plate 13 to enter the water at the same time, and the motor 7 24 is provided with a waterproof shell, so that there will be no failure due to entering the water;At this time, the steel wire rope 14 in the water will remain stable and will not sway due to the limitation of the groove plate 13 and the compression of the pressure strip 25. When the steel wire rope 14 wraps 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, so that the steel wire rope 14 can be used to lift the ship normally, thereby avoiding the steel wire rope 14 from swaying in the water due to the high water flow rate when the steel wire rope 14 enters the water, resulting in the steel wire rope 14 being unable to wrap around the ship accurately , 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 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, and there are impurities such as aquatic plants in the water. Some impurities are easy to follow the water flow to move to the groove of the groove plate 13, thereby causing the wire rope 2 14 to be stuck in the groove plate 13. When the groove plate 13 is far 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 far 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 2 and the guide column 29 and the second protrusion 23 are driven to move through the slide groove 20, so that the first protrusion 21 and the second protrusion 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 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. ;

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
