Description

Technical Field

[0001] This utility model belongs to the technical field of marine engineering equipment, and in particular relates to a sea vessel equipped with a side crane. Background Technology

[0002] Research vessels (also known as research ships or survey vessels) are specialized vessels designed for conducting scientific research, environmental surveys, and resource exploration in rivers, lakes, and oceans. Research vessels typically operate by deploying small scientific instruments (such as water samplers, benthic organism collectors, and underwater acoustic devices) into the sea, and then retrieving them from the sea after a specified period. Currently, these small instruments are generally deployed directly from the vessel into the sea. Therefore, during both deployment and retrieval, these small instruments are prone to collisions with the ship, resulting in damage. Utility Model Content

[0003] The purpose of this invention is to provide a seagoing vessel equipped with a side crane to solve the technical problems described in the background art.

[0004] A sea vessel equipped with a side crane includes a hull, with side cranes installed on both sides of the hull. The side crane includes a sleeve, a hook, and a rope control mechanism. The sleeve is fixedly installed on the hull, and a movable boom that can rotate 360° inward is inserted into the sleeve. An outwardly inclined bar is provided on the movable boom, and a pulley is installed at the outer end of the inclined bar. A steel cable is pulled out by the rope control mechanism, and the steel cable passes around the pulley to suspend the hook below the pulley.

[0005] The hoisting rope control mechanism is used to control the pulling out or winding of the steel cable to a specific length, thereby controlling the lifting and lowering of the hook. When the movable boom rotates, it drives the diagonal bar to swing, moving the hook outside or inside the ship. When the diagonal bar swings outside the ship, the hook moves away from the ship, so that the hook can be used to lift small scientific research instruments from the ship to the open sea.

[0006] Based on the technical solution, the present invention achieves the following beneficial effects:

[0007] 1. When deploying small scientific research instruments into the sea, the movable boom is rotated to swing the inclined bar into the hull. At the same time, the hoisting rope control mechanism releases and retracts the steel cable, allowing the hook to lift the small scientific research instrument from the hull. Then, the movable boom is rotated to swing the inclined bar out of the hull. At this point, the small scientific research instrument on the hook is away from the hull. Simultaneously, the hoisting rope control mechanism releases the steel cable, thus lowering the small scientific research instrument into the sea for operation. Therefore, it can avoid collisions with the hull and damage caused by the small scientific research instrument during the process of being deployed into the sea.

[0008] 2. After the small scientific research instrument has completed its work at sea, since the small scientific research instrument on the hook is far away from the hull, the small scientific research instrument can be taken out by controlling the hoisting rope control mechanism to rewind the steel cable. In this process, the small scientific research instrument can also avoid collision with the hull and damage.

[0009] 3. Because the small scientific research instruments can stay away from the hull, the movable boom and the sleeve during the process of being deployed into the sea and retrieved from the sea, the small scientific research instruments will not collide with the hull, the movable boom and the sleeve, thereby improving the safety of the operation.

[0010] 4. Compared to the conventional method of directly launching small scientific research instruments into the sea, the small scientific research instruments will not rub against the hull, movable boom and sleeve, which will increase the difficulty of operation, thus making operation easier and saving time and effort;

[0011] 5. This side crane, through its sleeve design, allows the movable boom to rotate 360 ​​degrees, thereby enabling efficient lifting of smaller samples and equipment. Compared to traditional cranes that move along the xyz axes, it can be easily installed on the sides or stern of the ship, reducing the space occupied by the crane within the hull and also reducing the power consumption of the crane during operation.

[0012] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0013] In some embodiments, the cable control mechanism includes a winding reel and a braking system, with the steel cable wound in the winding reel and the braking system being connected to the winding reel in a drive connection. The braking system can be a brake system.

[0014] The small scientific research instrument is allowed to fall into the sea by its own weight. At this time, the braking system is used to brake the reel to control the height of the small scientific research instrument.

[0015] Therefore, based on the above technical solution, the present invention can further achieve the following beneficial effects:

[0016] 1. Enables convenient placement of small scientific research instruments into the sea or hull within the ship;

[0017] 2. In the process of placing small scientific research instruments into the sea or lowering them into the hull of a ship, there is no need to rely on a power module to drive the reel to rotate, thus saving energy.

[0018] In some implementations, the winding reel is driven by a motor, and the braking system is a bidirectional braking system;

[0019] Based on the above technical solution, the following beneficial effects are further achieved:

[0020] 1. When lifting small scientific research instruments from the hull or from the sea, the steel cable can be wound up by rotating the winding reel driven by a motor, thus saving time and effort for the operator.

[0021] 2. The two-way braking system provides double protection and more balanced braking force to the winding reel when pulling out or winding up the steel cable, thereby improving the safety of the operator.

[0022] In some embodiments, the sleeve is provided with bolts that contact the movable boom, so that when the movable boom drives the diagonal bar to swing to a set angle, the bolts are used to clamp and fix the movable boom;

[0023] Based on the above technical solution, the movable boom can be stably fixed at the required angle, thereby preventing the diagonal boom from swaying due to airflow.

[0024] In some implementations, the side of the sleeve is fixedly connected to the hull's bulwark; based on the above technical solution, the ground occupation of the hull by the side crane is reduced.

[0025] In some embodiments, the sleeve is suspended above the ground of the hull, and an operating platform is provided on the ground below and around the sleeve, which is used to place small scientific research instruments.

[0026] Based on the above technical solutions, the hook can more stably and conveniently lift small scientific research instruments from the ship's hull to the sea, and from the sea back to the ship's hull.

[0027] In some embodiments, the sleeve is supported by a crane base plate, and the hoisting rope control mechanism is mounted on the crane base plate;

[0028] Based on the above technical solution, the hoisting rope control mechanism can be made to operate without occupying the ground of the ship.

[0029] In some embodiments, the sleeve is a steel pipe with an inner diameter of 80 mm and an outer diameter of 89 mm, the movable rod is another steel pipe with an inner diameter of 65 mm and an outer diameter of 76 mm, and the steel cable has a diameter of 5 mm.

[0030] Based on the above technical solution, the hoisting needs of small scientific research instruments can be met. At the same time, compared with traditional cranes, the equipment cost and power consumption during hoisting can be effectively reduced. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided with reference to the accompanying drawings.

[0038] like Figures 1 to 3 As shown in the figure, this specific embodiment provides a sea vessel equipped with side cranes, which includes a hull 1 and side cranes 2 are provided on both sides of the hull 1.

[0039] The side crane 2 includes a sleeve 3, a hook 4, and a rope control mechanism 5. The sleeve 3 is a stainless steel pipe with an inner diameter of 80 mm and an outer diameter of 89 mm. The side of the sleeve 3 is fixedly connected to the bulwark 11 of the hull 1, and the sleeve 3 is suspended above the ground 12 of the hull 1. The ground 12 is provided with an operating platform 13 located below and around the sleeve 3. The operating platform 13 is used to place small scientific research instruments, such as water samplers, benthic organism collectors, underwater acoustic equipment, and sampling instruments for collecting seabed mud samples and seawater samples.

[0040] A movable lifting rod 31, which can rotate 360° internally, is inserted into the sleeve 3. The movable lifting rod 31 is another stainless steel tube with an inner diameter of 65 mm and an outer diameter of 76 mm. The sleeve 3 is provided with a bolt 34 that contacts the movable lifting rod 31. When the movable lifting rod 31 drives the inclined rod 32 to swing to a set angle, the bolt 34 is used to clamp and fix the movable lifting rod 31. An inclined rod 32 is inclined outward on the movable lifting rod 31, and a pulley 33 is installed at the outer end of the inclined rod 32.

[0041] The sleeve 3 is externally supported by a crane base plate 53, and the crane base plate 53 is equipped with a hoisting rope control mechanism 5. The hoisting rope control mechanism 5 includes a winding reel 51 and a braking system 52. The braking system 52 is connected to the winding reel 51 and is a bidirectional braking system. The winding reel 51 is connected to a motor.

[0042] The winding reel 51 pulls out a steel cable 6, which goes around the pulley 33 and hangs the hook 4 below the pulley 33. The steel cable 6 has a diameter of 5 mm.

[0043] The following is a description of the operation of the seagoing vessel described in this embodiment.

[0044] When deploying a small scientific research instrument in the sea, rotating the movable boom 31 causes the inclined rod 32 to swing into the hull 1, moving the hook 4 above the small scientific research instrument on the operating platform 13. Then, controlling the bidirectional braking system 52 to stop braking the winding reel 51, the hook 4 falls under its own weight to contact and connect with the small scientific research instrument. Afterwards, the winding reel 51, driven by a motor or manually, winds up the steel cable 6, causing the hook 4 to rise and lift the small scientific research instrument off the operating platform 13. Subsequently, rotating the movable boom 31 causes the inclined rod 32 to swing into the hull 1, moving the hook 4 above the small scientific research instrument. When boom 32 swings outward, the small scientific instrument on hook 4 moves away from hull 1 and to a specific position. Bolt 34 clamps and secures the movable boom 31 to prevent the boom 32 from swaying due to wind and current. Then, the two-way braking system 52 stops braking the winding reel 51. At this time, the small scientific instrument on hook 4 falls into the sea under its own weight. When the small scientific instrument falls to a specific position in the sea, the double brakes on winding reel 51 are engaged to brake it. At this time, the small scientific instrument can work at a specific position in the sea.

[0045] After the small scientific research instrument completes its work at sea, the bidirectional braking system 52 stops braking the winding reel 51. At the same time, the motor or manual drive of the winding reel 51 winds up the steel cable 6, causing the hook 4 to rise and drop the small scientific research instrument out of the sea. After that, the bolt 34 is loosened to clamp and fix the movable boom 31. Then, the movable boom 31 is rotated to swing the diagonal bar 32 into the hull 1, so that the hook 4 moves to a position above the operating platform 13. After that, the bolt 34 clamps and fixes the movable boom 31, and the bidirectional braking system 52 stops braking the winding reel 51. At this time, the small scientific research instrument on the hook 4 falls under its own weight, so that the small scientific research instrument on the hook 4 is returned to the operating platform 13.
