[0029] The following detailed description provides various different embodiments or examples for implementing the present application. Of course, these are merely examples and are not intended to be limiting. Also, like reference numerals are used to designate corresponding parts throughout the several embodiments and views. These are used for a simple and clear description of the present application, and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0030] As Figures 1-9 ​​​The illustrated modular gangway includes a deck 1 and a gangway frame 2 hinged to the front of the deck 1. Several treads 3 are evenly spaced on the gangway frame 2, and anti-slip textures are provided on the treads 3. A hydraulic cylinder 91 is connected between the deck 1 and the gangway frame 2. A first hinge seat 92 is provided on the lower side of the deck 1, and a second hinge seat 93 is provided on the lower side of the gangway frame 2. The cylinder body of the hydraulic cylinder 91 is hinged to the first hinge seat 92, and the piston rod of the hydraulic cylinder 91 is hinged to the second hinge seat 93. Thus, the operation of the hydraulic cylinder 91 drives the gangway frame 2 to swing, thereby adjusting the tilt angle of the gangway frame 2 to adapt to use on ground at different heights.

[0031] Furthermore, each end of the pedal 3 is provided with a first rotating shaft 4, which is rotatably mounted on the gangway frame 2. A strip handle 5 is connected to each side of the gangway frame 2 via an adjustable connecting assembly. The strip handle 5 is parallel to the top of the gangway frame 2 and its height distance from the gangway frame 2 can be adjusted via the adjustable connecting assembly. A housing 6 is provided on one side of the gangway frame 2. A first power adjustment device and a second power adjustment device are respectively provided inside the housing 6. One end of the first rotating shaft 4 extends into the housing 6 and is connected to the first power adjustment device, and can be driven to rotate by the first power adjustment device. The lower end of the adjustable connecting assembly extends into the housing 6 and is connected to the second power adjustment device, and can be driven by the second power adjustment device to adjust the height distance between the strip handle 5 and the gangway frame 2.

[0032] According to the above structure, the step 3 can adjust its angle according to the tilt angle of the gangway frame 2, so that the step 3 is set horizontally as much as possible, thereby improving the safety when going up and down the gangway.

[0033] Alternatively, the first rotating shaft 4 can be driven to rotate by the first power adjustment device, so that the end faces of all the pedals 3 are on the same plane (e.g., Figure 4 As shown), this allows wheeled objects (such as bicycles) to move easily on the pedals 3; at the same time, the pedals 3 can be stored to reduce the overall size.

[0034] The strip handle 5 makes it easier for crew members to hold onto it when going up or down the gangway, improving safety during gangway use. In addition, the height distance between the strip handle 5 and the gangway frame 2 can be adjusted through an adjustable connecting component, so that the position of the strip handle can be adjusted according to the actual use situation to make it easier for crew members to use.

[0035] See Figure 5As shown, the first power adjusting device comprises a first gear 21 arranged on the first rotating shaft 4 and located in the box 6, a first rack 22 slidingly arranged in the box 6 and capable of engaging with the first gear 21, and a first push rod motor 23 arranged in the box 6 and used to drive the first rack 22 to slide.

[0036] When the first power adjusting device works, the first rack 22 is driven to slide by the first push rod motor 23, the first rack 22 engages with all the first gears 21, thereby driving all the first rotating shafts 4 and the pedal 3 to rotate, and the purpose of adjusting the angle of the pedal 3 is achieved, which is simple in structure and convenient to adjust.

[0037] As shown in Figure 1 , Figure 3 , Figure 4 As shown, the adjustable connecting assembly comprises a plurality of second rotating shafts 31 rotatably arranged on the gangway frame 2, a connecting rod 32 arranged on the second rotating shaft 31, and the upper end of each connecting rod 32 being hingedly connected to the strip-shaped handle 5; the strip-shaped handle 5 is adjusted in position by swinging the connecting rod 32.

[0038] Further, the left and right opposite second rotating shafts 31 are connected by a connecting shaft 41, so that the left and right connecting rods 32 can be connected, thereby driving one side of the connecting rod 32 to swing, and the other side of the connecting rod 32 also swings.

[0039] Further, the plurality of first rotating shafts 4 and the plurality of second rotating shafts 31 are sequentially and spacedly arranged; thereby one connecting rod is arranged between the two pedals 3, effectively and reasonably utilizing the space.

[0040] As shown in Figure 5 As shown, the second power adjusting device comprises a second gear 51 arranged at one end of the second rotating shaft 31 and located in the box 6, a second rack 52 slidingly arranged in the box 6 and capable of engaging with the second gear 51, and a second push rod motor 53 arranged in the box 6 and used to drive the second rack 52 to slide.

[0041] When the second power adjusting device works, the second rack 52 is driven to slide by the second push rod motor 53, the second rack 52 engages with all the second gears 51, thereby driving all the second rotating shafts 31 to rotate, and the connecting rod 32 to swing, and the purpose of adjusting the position of the strip-shaped handle 5 is achieved, which is simple in structure and convenient to adjust.

[0042] It should be noted that the first gear 21 and the second gear 51 are not located in the same plane, i.e. the first gear 21 is arranged inwardly a little bit, and the second gear 51 is arranged outwardly a little bit, thereby not affecting the sliding work of the first rack 22 and the second rack 52.

[0043] In order to guarantee the stability of the pedal 3 and the strip-shaped handle 5, a locking device is arranged in the box 6 to lock the first gear 21 and the second gear 51.

[0044] Referring to Figures 6-9 As shown, the locking device comprises a plurality of first locking holes 71 arranged on the end surface of the first gear 21 in a circumferential direction, a plurality of second locking holes 72 arranged on the end surface of the second gear 51 in a circumferential direction, a plate body 73 sliding leftward and rightward in the box 6, a first locking column 74 arranged on one end of the plate body 73 and matched with the first locking hole 71, a second locking column 75 arranged on the other end of the plate body 73 and matched with the second locking hole 72, a guide column 76 arranged on the outer end of the plate body 73 and movably arranged in the box 6, a transverse sliding groove 77 arranged on the outer side of the plate body 73, and a motor 78 arranged in the box 6 and having an L-shaped eccentric column 79 arranged on the output shaft of the motor 78.

[0045] When the locking device is in a locking operation, the L-shaped eccentric column 79 is driven to rotate by the motor 78, the L-shaped eccentric column 79 moves in the transverse sliding groove 77 and drives the plate body 73 to move, and then the first locking column 74 is inserted into the first locking hole 71 and the second locking column 75 is inserted into the second locking hole 72, thereby locking the first gear 21 and the second gear 51, and finally locking the pedal 3 and the strip-shaped handle 5. Similarly, when the locking device is in an unlocking operation, the first locking column 74 is separated from the first locking hole 71 and the second locking column 75 is separated from the second locking hole 72, thereby unlocking the first gear 21 and the second gear 51.

[0046] It is worth mentioning that the frequency of adjusting the pedal 3 is more than that of adjusting the strip-shaped handle 5, and therefore, in order to not unlock the strip-shaped handle 5 when adjusting the pedal 3, the first gear 21 is arranged inwardly and the second gear 51 is arranged outwardly, that is, the second gear 51 is closer to the plate body 73, and the length of the first locking column 74 is shorter than that of the second locking column 75, so that when the first locking column 74 is separated from the first locking hole 71, the second locking column 75 has not been separated from the second locking hole 72, and then the first gear 21 is unlocked and can be adjusted, while the second gear 51 is in a locked state and cannot be adjusted.

[0047] Those skilled in the art should understand that the present application is not limited by the above-mentioned embodiments and the description in the specification, and the principle of the present application can be variously changed and improved without departing from the spirit and scope of the present application, and all the changes and improvements fall within the scope of the present application. The scope of the present application is defined by the appended claims and their equivalents.
