Description

Technical Field

[0001] This application relates to the technical field of ships, and specifically to a lifting ladder for ships. Background Art

[0002] As an important tool for maritime transportation, ships carry a large amount of goods and passengers. When a ship docks at a large ship terminal, the goods on the ship need to be loaded and unloaded, and the passengers on the ship may also need to transfer.

[0003] At this time, the lifting ladder becomes an important bridge connecting the land and the ship, ensuring that the loading and unloading personnel and crew can safely and smoothly get on and off the ship.

[0004] For example, the patent with the publication number CN207843241U discloses a marine lifting ladder. This patent adjusts the inclination angle of the ladder body through directional rollers, thereby adjusting the height of the ladder body. It is widely used in the ship field. Anti-algae pads are provided on each step board to prevent the surface from getting wet and generating algae, which may affect the walking of personnel.

[0005] However, in actual operation, the ship may not use the lifting ladder for a long time during navigation. If the lifting ladder is not stored when not in use, it will increase the potential danger on the ship, may obstruct the passage of personnel, increase the risk of collision and falling, and thus lead to more serious accidents.

[0006] Therefore, it is necessary to provide a marine lifting ladder to solve the above problems.

Detailed implementation manners

[0035] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0036] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0037] As Figure 1 - Figure 2 and Figure 4 shown, this application provides a lifting ladder for a ship, including a ladder body 2. The ladder body 2 is the main structure of the lifting ladder, which is used to bear the weight of personnel and goods and provide a path for lifting;

[0038] The ladder body 2 includes two groups of first guard rails 20. A plurality of foot plates 21 are fixedly arranged between the first guard rails 20. The foot plates 21 are used to provide stable support for the lifting ladder. At the same time, the upper end of the foot plate 21 is made of anti-slip material to prevent personnel or goods from slipping;

[0039] Meanwhile, in order to adapt to the distances between different ships and docks, two connecting plates 22 are fixedly arranged at the lower ends of two groups of first guardrails 20, and two groups of second guardrails 24 are rotatably arranged on the two connecting plates 22. A plurality of foot plates 21 are also fixedly arranged between the two groups of second guardrails 24;

[0040] When it is necessary to adjust the length of the ladder body 2 to adapt to different distances, the two groups of second guardrails 24 can be pulled so that the second guardrails 24 rotate around the connecting plates 22 until they cannot rotate. Finally, the ends of the second guardrails 24 can be placed on the dock shore (refer to Figure 2 );

[0041] Two fixing plates 25 are fixedly arranged at the ends of the two groups of first guardrails 20 away from the connecting plates 22. At the same time, two groups of baffles 26 are rotatably arranged on the two fixing plates 25. The baffles 26 are used to block the use of the second guardrails 24. At the same time, a screw 27 is threadedly connected at the connection between the baffle 26 and the fixing plate 25. The screw 27 is used for locking and unlocking the baffle 26. When the screw 27 is rotated close to the baffle 26, the baffle 26 can be locked to prevent the baffle 26 from falling off due to the self - gravity of the second guardrail 24. On the contrary, when the screw 27 is rotated away from the baffle 26, the baffle 26 can be unlocked;

[0042] At the same time, a placement groove (not shown in the figure) is fixedly arranged at the bottom end of the baffle 26. The placement groove is used to place the ends of the second guardrails 24 when the ladder body 2 does not need to be extended;

[0043] When it is necessary to extend the ladder body 2, only need to rotate the screw 27 to unlock the baffle 26, and then rotate the baffle 26 around the fixing plate 25 in the opposite direction to the rotation of the second guardrail 24 around the connecting plate 22, then the second guardrail 24 can be unlocked, so as to achieve the purpose of extension;

[0044] As Figure 1 - Figure 3 and Figure 5 shown, in order to prevent the lifting ladder from affecting the operation of the ship when not in use, and for quick operation during the next use, and at the same time enable the lifting ladder to adapt to working environments at different angles, a retracting and deploying mechanism 3 is fixedly arranged on the ladder body 2;

[0045] The retracting and deploying mechanism 3 includes a base 41 fixedly installed on the ship, and two groups of columns 31 fixedly arranged at the upper end of the base 41. A fixed end 40 is arranged at the upper end of the column 31. The fixed end 40 is used to fix the ladder body 2. At the same time, a fixed seat 32 is fixedly installed on the column 31, and an adjustment component is installed on the fixed seat 32. The adjustment component is used to store the ladder body 2 when the ladder body 2 is not in use, and at the same time can adjust the inclination angle and height of the ladder body 2 to different degrees, so as to adapt to different working environments;

[0046] The adjustment component includes an electric push rod 33 rotatably arranged on the fixed seat 32. A connecting rod 37 is rotatably arranged at the output end of the electric push rod 33 so that the electric push rod 33 can push the connecting rod 37 to rotate;

[0047] Meanwhile, two mounting plates 35 are fixedly arranged on the upper end of the base 41 near the two groups of columns 31. A connecting head 36 is rotatably arranged on the mounting plate 35. One end of the connecting head 36 is fixedly provided with an extension rod 38, which is used to fix the ladder body 2. A plurality of fixing bolts 30 are threadedly connected to the extension rod 38. The extension rod 38 is connected to the ladder body 2 through the fixing bolts 30. Meanwhile, a handle 39 is fixedly arranged on the extension rod 38, which is used to pull the extension rod 38;

[0048] And one end of the extension rod 38 close to the connecting head 36 is fixedly connected to the connecting rod 37, so that when the electric push rod 33 pulls the connecting rod 37, it can drive the extension rod 38 to rotate around the mounting plate 35, thereby driving the ladder body 2 to rotate, and further achieving the purpose of adjusting the angle of the ladder body 2;

[0049] Meanwhile, when the lifting ladder is not in use, the electric push rod 33 can be used to pull the ladder body 2 to rotate around the mounting plate 35 until the first guardrail 20 is in a vertical state (refer to Figure 3 ), that is, the storage operation is completed. Finally, a rope or wire is used to fix the ladder body 2 through the fixed end 40 at the upper end of the column 31, so as to prevent the ladder body 2 from falling;

[0050] When in use, only need to unlock the ladder body 2, pull the handle 39 on the extension rod 38 to make the ladder body 2 rotate around the mounting plate 35, and finally use the electric push rod 33 to adjust the angle of the ladder body 2.

[0051] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
