[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 A hydraulic safety gangway for a transport vessel includes: a gangway body formed by combining a main gangway 1 and an auxiliary gangway 2, wherein the main gangway 1 and the auxiliary gangway 2 are rotatably connected, and the rotatable parts of the main gangway 1 and the auxiliary gangway 2 are connected by an adjustment device 3. The end of the main gangway 1 away from the auxiliary gangway 2 is rotatably mounted on the ship, and the side of the main gangway 1 is connected to a drive mechanism 9 installed on the ship through a reinforcing frame 7. The end of the auxiliary gangway 2 away from the main gangway 1 is mounted on the dock through a rotatably mounted support mechanism 4.

[0019] The main gangway 1 and the auxiliary gangway 2 are respectively equipped with a first protection 5 and a second protection 6. The first protection 5 and the second protection 6 overlap at the junction of the main gangway 1 and the auxiliary gangway 2. The first protection 5 and the second protection 6 are both formed by a combination of handrails and protective nets. The junction of the first protection 5 and the second protection 6 is staggered to avoid obstruction between the first protection 5 and the second protection 6. When pedestrians pass through, the junction ensures that changes in the main body of the gangway will not affect the protection effect.

[0020] The reinforcing frame 7 includes a lifting seat 71 located on the side of the main gangway 1. The lifting seat 71 has a lifting slot 73 for cooperating with the drive mechanism 9. The lifting seats 71 located on both sides of the main gangway 1 are connected to the bottom of the main gangway 1 by a crossbar. When the ship is sailing, the lifting force of the drive mechanism 9 is used to make the gangway body stand up, which has a folding effect and reduces the deck space occupied by the gangway body on the ship.

[0021] The gantry 71 is welded with a vertical bridge 72. The end of the main gangway 1 closest to the ship is rotatably mounted with the ship via an end seat 8. Both sides of the bridge 72 are provided with arch ribs 74 that are inclined relative to the main gangway 1. The arch ribs 74 on both sides of the bridge 72 are connected to the adjustment device 3 and the end seat 8, respectively. Given the long length of the main gangway 1, the bridge 72 and arch ribs 74 are used to strengthen both ends of the main gangway 1, thereby increasing the strength of the gangway.

[0022] The support mechanism 4 includes a support base 41 rotatably mounted on the auxiliary gangway 2. The bottom of the support base 41 is welded with a center frame 42, a ramp frame 43, and a counterweight frame 44. The bottoms of the center frame 42, the ramp frame 43, and the counterweight frame 44 are connected by a crossbar, and rubber wheels 46 for contacting the dock surface are installed on the crossbar. Multiple sets of steps 45 are welded sequentially on the ramp frame 43. When the gangway is lowered, if the water level is high, the support mechanism 4 can adaptively connect with the dock as the bending degree of the main gangway 1 and the auxiliary gangway 2 changes, avoiding the situation of the head tilting.

[0023] The central frame 42, the ramp frame 43, and the counterweight frame 44 form a triangular frame structure, and the structural weights on the front and rear sides of the central frame 42 are the same. The weights of the central frame 42 and the counterweight frame 44 are used to maintain the balance of the structures on both sides of the central frame 42, thereby ensuring the balance of the support mechanism 4 when it is mounted on the wharf, without the need for manual adjustment.

[0024] The adjustment device 3 includes a first support 31 on the main gangway 1 and a second support 32 on the auxiliary gangway 2. A hydraulic cylinder 33 is provided between the first support 31 and the second support 32 via a transition seat. An auxiliary support frame 34 extends from one side of the first support 31, which is attached to the outer wall of the main gangway 1. The end of the auxiliary support frame 34 is rotatably connected to the auxiliary gangway 2. When the water level is high at the dock where the ship is moored, the extension and retraction of the hydraulic cylinder 33 can be controlled according to the water level difference, thereby ensuring that the support mechanism 4 is stably mounted on the dock and that the crew can walk safely on the gangway.

[0025] The drive mechanism 9 includes a retraction frame 91 installed on the ship and used to cooperate with the main gangway 1. A guide roller 92 is installed on the side of the retraction frame 91 near the main gangway 1. A hoisting rope 93 is rolled on the guide roller 92. One end of the hoisting rope 93 is connected to the reinforcing frame 7, and the other end of the hoisting rope 93 is connected to the winch 94 installed on the ship. Before the ship leaves the dock, the winch 94 can be used to wind up the hoisting rope 93 to pull the gangway body upright, achieving the retraction effect. The drive mechanism 9 can also be replaced with other mechanisms that have the effect of retracting the gangway body, depending on the specific situation of the ship.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
