[0024] Example 1:

[0025] like Figure 1 As shown in Figure 2, a marine telescopic gangway support structure includes a base 14, which is fixed to the deck. A side frame 2 and a telescopic unit are provided above the base 14. The telescopic unit drives the side frame 2 to move along the base 14. A base plate 3 is provided on the side of the side frame 2 away from the base 14. An opening is provided in the middle of the base plate 3. A ladder 7 is provided at the opening. The side frame 2 is provided with a retraction unit. One end of the ladder 7 is hinged to the base plate 3. The retraction unit drives the other end of the ladder 7 to rise and fall.

[0026] The marine telescopic gangway support structure of this embodiment adopts a retraction unit, which can quickly retract and extend the ladder 7. The operation is quick and convenient, and the retraction and extension speed is fast. Moreover, in conjunction with the drive unit, the base plate 3 and the ladder 7 can quickly extend out of the deck or retract to the base 14 located on the deck, while preventing the ladder 7 from being suspended on the outside of the ship's side during navigation.

[0027] The drive unit includes two electric cylinders 4, which are fixed at both ends of the base 14. The output shaft of the electric cylinder 4 is fixedly connected to the side frame 2. The operator controls the electric cylinder 4 to work, so that the base plate 3 and the ladder 7 can quickly extend out of the deck or retract to the base 14 located on the deck. Moreover, the electric cylinder 4 can be replaced with a lead screw and a nut. The operator manually rotates the lead screw to move the nut, thereby moving the side frame 2 and the base plate 3.

[0028] The base 14 is evenly provided with a plurality of guide rails 1, and the side frame 2 and the bottom plate 3 are provided with a plurality of sliders 5, which slide in cooperation with the guide rails 1.

[0029] The retraction unit includes a motor 8 and a main shaft 9. The motor 8 is fixed to the side frame 2 and drives the main shaft 9 to rotate. Both ends of the main shaft 9 are provided with drums 10, and steel wire ropes 12 are wound on the drums 10. The bottom end of the steel wire ropes 12 is fixed to the ladder 7. The motor 8 drives the main shaft 9 to rotate, which can make the two drums 10 rotate, thereby loosening the steel wire ropes 12 and allowing the ladder 7 to be lowered, or the drums 10 rotate in the opposite direction, causing the ladder 7 to be quickly retracted.

[0030] The base plate 3 is provided with a bracket 11 on the side away from the side frame 2, and the end of the main shaft 9 away from the motor 8 passes through the bracket 11.

[0031] The side frame 2 is equipped with several counterweights; since the base plate 3 and the ladder 7 extend out of the base 14, the side frame 2 needs to be equipped with counterweights to prevent the side frame 2 from detaching from the guide rail 1.

[0032] The ladder 7 is equipped with guardrails 13 on both sides; the guardrails 13 can protect the people getting on and off the ship.

[0033] The guide rail 1 is provided with a positioning block 6 on the side away from the base plate 3; the positioning block 6 can prevent the side frame 2 from moving too far backward and disengaging from the guide rail 1.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
