Technical Field

[0001] The utility model relates to the technical field of marine stairs, in particular to a marine multi-functional folding boarding ladder. Background Technique

[0002] In the development process of oil tanker terminals, modern large oil tanker terminals, especially those on open-piled terminals without shelter, have large fenders at the terminals, and the distance from the ship's side docked at the terminal to the quay line is relatively large. The connection between the ship and the shore under such conditions is difficult to solve with the gangway carried by the oil tanker. Therefore, in order to accelerate the ship loading and unloading operations and ensure the safety of personnel getting on and off the ship at modern large oil tanker terminals, it is an inevitable choice to replace the ship's gangway with a boarding ladder.

[0003] The traditional boarding ladder allows a fixed flow of people to pass through. The fixed flow of people can meet the usage requirements during normal periods. However, in case of emergencies on the ship, the flow of people allowed to pass through the ordinary boarding ladder cannot meet the actual needs, and it is easy to cause safety accidents. Therefore, a marine multi-functional folding boarding ladder is proposed to solve the above-mentioned problems. Content of the Utility Model

[0029] Please refer to Figure 1 and Figure 2 , a marine multi-functional folding boarding ladder, comprising:

[0030] The main body of the ship ladder 1, which includes a first side plate 11, a second side plate 12, a mounting through hole 13, a limiting block 14, a stress cross bar 15, an opening 16 and a guiding hole 17, wherein,

[0031] The first side plate 11 and the second side plate 12 are connected to each other by screws. Stress cross bars 15 are provided on opposite sides of the first side plate 11 and the second side plate 12, and adjacent stress cross bars 15 are connected to each other by screws. Limiting blocks 14 are provided on the upper surfaces of the first side plate 11 and the second side plate 12, and an opening 16 is provided on the surface of the limiting block 14;

[0032] Mounting through holes 13 and guiding holes 17 are respectively provided at the top and side of the first side plate 11 and the second side plate 12. The mounting through holes 13 and the guiding holes 17 are communicated with each other, and the guiding holes 17 provided on the surface of the first side plate 11 and the guiding holes 17 provided on the surface of the second side plate 12 are arranged in a staggered manner;

[0033] Based on the above, the first side plate 11, the second side plate 12 and the stress cross bar 15 are connected to each other by screws. At this time, on the one hand, the stress cross bar 15 plays a role in supporting and limiting the lateral moving block 4, and on the other hand, the lateral moving block 4 plays a role in bearing the behavior of walking. The guiding hole 17 plays a role in guiding the movement of the lateral moving block 4. The limiting block 14 and the opening 16 cooperate with each other, so that while the position of the handrail frame 3 is fixed, the vertical position of the handrail frame 3 can be adjusted.

[0034] As Figure 1 , Figure 4 and Figure 5 shown, the first movable plate 2 and the second movable plate 5 are provided with lateral moving blocks 4 on their opposite sides. The lateral moving blocks 4 penetrate through the guiding holes 17 and extend between the first side plate 11 and the limiting block 14;

[0035] The transverse moving blocks 4 provided on the opposite sides of the first movable plate 2 and the second movable plate 5 are arranged in a staggered manner. The width of the transverse moving block 4 provided on one side of the first movable plate 2 near the first movable plate 2 is smaller than the width of the side away from the first movable plate 2. The width of the transverse moving block 4 provided on one side of the second movable plate 5 near the second movable plate 5 is smaller than the width of the side away from the second movable plate 5;

[0036] The transverse moving block 4 includes a positioning blind hole 43 and a positioning through hole 44. The transverse moving block 4 includes a transverse block 41. Guide grooves 42 are provided on both sides of the transverse block 41. The force-bearing cross bar 15 is in contact with the inner wall of the guide groove 42. Positioning blind holes 43 and positioning through holes 44 are respectively provided at both ends of the upper surface of the transverse block 41. The positioning blind hole 43 is provided at the end with a smaller width of the transverse block 41;

[0037] Based on the above, both the first movable plate 2 and the second movable plate 5 play a role in limiting the transverse moving block 4 and provide support. The transverse moving block 4 cooperates with the force-bearing cross bar 15. The transverse moving block 4 is supported and guided by the force-bearing cross bar 15, so that the transverse moving block 4 can provide support whether it moves along the direction of the force-bearing cross bar 15 or not. The positioning blind hole 43 and the positioning through hole 44 respectively cooperate with the handrail frame 3, so that the position of the transverse moving block 4 is fixed.

[0038] As Figure 1 and Figure 3 shown, the handrail frame 3 includes a first cross bar 31 and a positioning vertical bar 33. Among them,

[0039] The first cross bar 31 is arranged inside the opening 16 by screws. The handrail frame 3 includes a first cross bar 31 and a second cross bar 32. A positioning vertical bar 33 is provided between the first cross bar 31 and the second cross bar 32. The positioning vertical bar 33 passes through the installation through hole 13 and extends into the positioning blind hole 43. Threaded holes 34 are provided at both ends of the first cross bar 31. The screws are threadedly connected to the threaded holes 34 and are in contact with the limiting block 14;

[0040] Based on the above, on the one hand, the handrail frame 3 functions as a handrail, and after the ship ladder is unfolded, it can carry out diversion operations on people. On the other hand, the handrail frame 3 plays a role in fixing the transverse moving block 4. The threaded holes 34 cooperate with the screws, so that the handrail frame 3 and the limiting block 14 are fixed to each other, and the handrail frame 3 can also be fixed after vertical movement.

[0041] When this embodiment is actually used, the first side plate 11 and the second side plate 12 are connected to each other by screws. Before connection, the transverse movable block 4 is placed between the two side plates, and the transverse movable block 4 is respectively connected to the first movable plate 2 and the second movable plate 5 by screws. Then, the handrail frame 3 and the screws are cooperated to be fixed at the opening 16. At this time, the installation of the boarding ladder is completed;

[0042] When actually used, Figure 1 it is the storage state of the transverse movable block 4. This state is only for the normal use of the ship. If an emergency occurs on the ship, the handrail frame 3 can be lifted upward after loosening the screws. At this time, the transverse movable block 4 is pulled horizontally to make the transverse movable block 4 in the unfolded state. After the handrail frame 3 is released, the positioning vertical rod 33 is inserted into the positioning through hole 44 and the screws are tightened to fix the position of the handrail frame 3. When the position of the handrail frame 3 is fixed, the position of the transverse movable block 4 is fixed together;

[0043] After the transverse movable block 4 is unfolded, the boarding ladder can allow a larger flow of people to pass through. At this time, the handrail frame 3 can divert the flow of people. Compared with the traditional boarding ladder, this boarding ladder has three states. The first state is Figure 1 the normal state in, the second state is the state where the unilateral transverse movable block 4 is unfolded, and the third state is Figure 6 the unfolded state in. Whether it is the second state or the third state, the flow of people allowed to pass through can be increased to cope with the emergencies faced by the ship.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
