Description

Technical Field

[0001] The utility model relates to the technical field of gangways, in particular to a gangway for boarding a ship. Background Technique

[0002] A gangway is a connection passage between a ship and the land built after the ship docks. According to the building method, it can be divided into two categories: shipborne type and land type. The shipborne type can extend directly from the hull to the land, while the land type needs to be manually hung on the hull by workers.

[0003] The ends of the existing land gangways usually have two groups of hooks, which are connected to the hull through the hooks to ensure the stability of the connection state of the gangway. However, this hanging connection method usually only has good adaptability to the undulation of the ship. In some slight lateral offsets, there will be a certain twist between the ship and the hooks. Long-term twisting is likely to cause irreversible rigid deformation of the hooks, which is not convenient for subsequent hanging, and at the same time, the stability of the hanging cannot be guaranteed. When unloading large-weight goods, there will be a situation where the boarding ladder of a fully loaded ship at low tide berth cannot be placed on the ship's deck, resulting in personnel being unable to board the ship, seriously delaying the orderly production of the company.

[0004] In the patent document with the publication number of CN215971990U, a safe gangway for easy boarding is disclosed. Through the mutual cooperation of the movable groove, the movable rod, the spring and the rubber abutting head, during the process of the hook moving along the ship's side, when the hook offsets to which side, the rubber abutting head on that side is forced to push the movable rod to slide along the inside of the movable groove. At the same time, during the sliding process of the movable rod, the spring is pushed to deform and store energy. When the force is removed, the spring returns to its initial state. Under the action of the elastic force of the spring, the movable rod pushes the rubber abutting head to move to the initial position, so that the connecting plate always maintains a normal straight state, facilitating the normal hanging of the hook.

[0005] However, when the safe gangway for easy boarding is actually used, when unloading large-weight goods, there will be a situation where the boarding ladder of a fully loaded ship at low tide berth cannot be placed on the ship's deck, resulting in personnel being unable to board the ship, seriously affecting the production efficiency. Therefore, a gangway for boarding the ship's deck needs to be proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a gangway for boarding a ship, so as to solve the problem that the operation cannot be carried out on time due to the boarding ladder of the oil tanker being unable to connect to the ship's deck as mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A gangway for boarding a ship, including a main ladder and a front ladder arranged on the left side of the main ladder. A first adjusting mechanism is arranged on one side of the main ladder, and a second adjusting mechanism is arranged at the bottom of the front ladder;

[0008] The first adjustment mechanism includes a first mounting seat, a main ladder oil cylinder, a second mounting seat, a first extension plate and a second extension plate. The first mounting seat is fixedly connected to the bottom of the main ladder. The main ladder oil cylinder is rotatably connected to one side of the first mounting seat. The second mounting seat is fixedly connected to the bottom of the front ladder. The first extension plate is fixedly connected to the left side of the main ladder. The second extension plate is fixedly connected to the right side of the front ladder.

[0009] Preferably, the second adjustment mechanism includes a third mounting seat, a front ladder oil cylinder, a fourth mounting seat, a triangular ladder and universal rubber rollers. The third mounting seat is fixedly connected to the bottom of the front ladder. The front ladder oil cylinder is rotatably connected to one side of the third mounting seat. The triangular ladder is rotatably connected to one side of the front ladder. The fourth mounting seat is fixedly connected to one side of the triangular ladder. The universal rubber rollers are arranged at the bottom of the triangular ladder.

[0010] Preferably, a main guardrail is fixedly connected to the top of the main ladder, and a front guardrail is fixedly connected to the top of the front ladder. The main guardrail and the front guardrail will not interfere when the angles of the main ladder and the front ladder change, and play a protective role when people board the ship.

[0011] Preferably, the first extension plate is rotatably connected to one side of the second extension plate. After the main ladder oil cylinder is started and contracts, it will pull the side of the front ladder back towards the direction where the main ladder is located. At this time, the second extension plate will rotate around the first extension plate.

[0012] Preferably, one end of the main ladder oil cylinder is rotatably connected to the first mounting seat, and the other end is rotatably connected to the second mounting seat. Two main ladder oil cylinders are evenly distributed at the bottom of the main ladder.

[0013] Preferably, one end of the front ladder oil cylinder is rotatably connected to the third mounting seat, and the other end is rotatably connected to the fourth mounting seat. The front ladder oil cylinder is used to adjust the angle between the front ladder and the triangular ladder so that the bottom of the triangular ladder can always be flush with the deck.

[0014] Preferably, three universal rubber rollers are evenly distributed at the bottom of the triangular ladder, and the three universal rubber rollers are always perpendicular to the deck.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. For the boarding ladder used in this case, through the first adjustment mechanism provided, and the main ladder oil cylinders arranged at the bottoms of the main ladder and the front ladder, the hydraulic cylinders are self-locking after being in place, so that the main ladder can be adjusted in position, and then the angle between the main ladder and the front ladder can be adjusted to adapt to the ship's drift and improve the height of the boarding ladder itself. No matter how the working angle of the ladder changes, the tread plate always remains horizontal, realizing the smooth connection of the boarding ladder for the ship when berthed at low tide and fully loaded and the normal boarding of personnel, effectively ensuring the orderly development of production and improving the operation efficiency.

[0017] 2. The boarding ladder is provided with a second adjustment mechanism. There is a front ladder oil cylinder between the front ladder and the triangular ladder. The triangular ladder is supported by three universal rubber roller support points and always remains perpendicular to the ship's deck. The entire boarding ladder rotates to adapt to the different layouts of various ship deck surfaces and the placement of the boarding ladder on the wharf surface under non-working conditions.
