Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to an automatic lifting device for boarding and leaving ships. Background Art

[0002] With the development of modern ship technology, large-scale ships are becoming more and more prominent. At present, large ships of 100,000 tons, 200,000 tons and 300,000 tons are very common, and there will be more and more ships of larger sizes. The freeboard of these large ships is often more than ten meters or even more, which causes great inconvenience to people boarding and leaving the ship. At present, the main ways for people to board and leave ships in daily work are, first, through the gangway, second, through the pilot ladder, and third, the combination of the pilot ladder and the gangway. The larger the ship, the longer the gangway and the pilot ladder. It is very inconvenient and even difficult for people to board and leave the ship, especially when carrying some ship materials and accessories or crew meals, and it is accompanied by personal danger. Especially when the pilot wants to board the incoming ship to carry out pilotage work, he must first climb up the pilot ladder of more than ten meters or even longer to board the sailing ship. This process is not only difficult but also dangerous in wind and waves. In real work, there are occasional cases where pilots fall and get injured when climbing the pilot ladder to board the ship.

[0003] In order to solve these problems, there are devices that use winches to pull manned frame structures to get on and off ships; in special occasions, people use hoisting machinery on the deck to lift manned hanging baskets and ship materials to achieve the purpose of boarding and leaving the ship. These practices are difficult to be widely promoted in actual shipping work due to the imperfect design of the entire set of devices, which leads to inconvenience in specific work and lack of safety assurance.

[0004] In order to solve the above problems, an automatic lifting device for boarding and leaving a ship is urgently needed. Utility Model Content

[0005] The utility model aims to provide an automatic lifting device for boarding and leaving a ship. By arranging the lifting device outside the hull, people can directly reach the deck through the lifting device without going through a gangway or a pilot ladder.

[0021] Example

[0022] like Figure 1 As shown, the utility model discloses an automatic lifting device for boarding and disembarking from a ship. The utility model will be further described in detail below in conjunction with specific embodiments.

[0023] In a specific implementation, a plurality of rows of rolling wheels 13 are arranged on the side of the manned mechanism close to the hull, and these rolling wheels 13 can ensure that the manned mechanism moves smoothly along the hull shell and the outer side wall of the support mechanism during the lifting process, thereby reducing friction and resistance. A power mechanism fixed on the deck of the ship is provided with a reel 21. The power mechanism can be driven by a motor, and the reel 21 is driven by the motor to rotate, thereby realizing the retracting and releasing operation of the transmission member 4.

[0024] The support mechanism is fixed on the deck of the ship, and the support mechanism includes a square column 31 with one side flush with the hull and a support frame 32 fixedly connected to the top of the square column 31. The directional pulley 33 is connected to the support frame 32 through a positioning shaft, and the directional pulley 33 can rotate around its axis. The directional pulley 33 provides guidance and support for the transmission component 4 to ensure the directional stability of the transmission component 4 during operation.

[0025] One end of the transmission member 4 is connected to the tripod hanger 11, and the other end is fixedly connected to the drum 21, and the middle part of the transmission member 4 abuts against the top of the directional pulley 33. When the power mechanism drives the drum 21 to rotate, the rotation of the drum 21 is transmitted to the manned mechanism through the transmission member 4, so that the manned mechanism can be raised or lowered.

[0026] As a preferred embodiment of the above technical solution, the bottom plate 12 of the manned mechanism provides a platform for people to stand or sit. The four corners of the bottom plate 12 are fixedly connected with support columns 121 respectively. Since the support columns 121 are arranged at the four corners of the bottom plate 12, the two support columns 121 on the side close to the hull of the manned mechanism just form a back door, and the two support columns 121 on the side away from the hull form a front door. The carrier can directly enter and exit through these two doors. Multiple rows of rolling wheels 13 are fixedly connected to the support columns 121 on the side close to the hull through rolling shafts, and the rolling wheels 13 can rotate around their own axis. During the lifting process, the rolling wheels 13 contact and roll with the outer wall of the hull and the support mechanism. In actual use, the carrier will stand on the bottom plate 12. As the manned mechanism continues to rise, when the bottom plate 12 is flush with the deck of the ship, the carrier can smoothly reach the deck. When the carrier wants to reach the ground or the small pick-up vessel under the large ship from the deck, he only needs to enter the bottom plate 12 from the deck. As the manned mechanism continues to descend, when the manned mechanism reaches the corresponding position, the carrier can smoothly reach the ground or the small pick-up vessel under the large ship.

[0027] As a preferred implementation of the above technical solution, an expansion slot 122 is provided on the bottom plate 12, and a motor is provided on each of the two sides of the expansion slot 122, and a gear is mounted on the output shaft of the motor; an expansion plate 123 is also provided inside the expansion slot 122, and racks 1231 adapted to the gear are provided on both sides above the expansion plate 123. In actual use, sometimes the docking position of the ship will be a certain distance from the shore, and it will be very inconvenient for the carrier to board the ship due to the distance. Therefore, when encountering this situation, the linear motion of the expansion plate 123 can be realized through the mutual cooperation of the gear and the rack 1231, so that the expansion plate 123 can automatically extend out of the expansion slot 122, and the carrier can easily enter the bottom plate 12 through the expansion plate 123.

[0028] As a preferred implementation of the above technical solution, the two support columns 121 on the left and right sides of the bottom plate 12 are both provided with protective plates 14. The protective plates 14 can provide effective side protection for the passengers on the bottom plate 12 during the lifting process of the passenger-carrying mechanism, preventing the passengers from accidentally sliding off the sides of the bottom plate 12.

[0029] As a preferred embodiment of the above technical solution, a top plate 111 is provided above the triangular hanger 11. The top plate 111 can prevent cargo, especially bulk cargo such as coal, ore, etc., from spilling and falling on the body of the loader during loading and unloading, causing injury or soiling the body, and can also prevent rain.

[0030] As a preferred implementation of the above technical solution, the multiple rows of rolling wheels 13 are arranged in double rows, and the number of rolling wheels 13 in each row is multiple. The distribution of the double rows of rolling wheels 13 makes the contact and support between the manned mechanism and the hull more uniform. The number of rolling wheels 13 in each row is multiple, which makes the manned mechanism more stable during operation.

[0031] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
