In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0030] like Figure 1-Figure 9A combined gangway ladder is shown, comprising a deck 1 and a gangway frame 2 hinged to the front side of the deck 1, a plurality of pedals 3 are evenly spaced on the gangway frame 2, anti-slip grooves are arranged on the pedals 3, a hydraulic cylinder 91 is also connected between the deck 1 and the gangway frame 2, a first articulated seat 92 is arranged on the lower side of the deck 1, a second articulated seat 93 is arranged on the lower side of the gangway frame 2, the cylinder body of the hydraulic cylinder 91 is hinged to the first articulated seat 92, and the piston rod of the hydraulic cylinder 91 is hinged to the second articulated seat 93; thus, the gangway frame 2 can be driven to swing by the operation of the hydraulic cylinder 91, thereby adjusting the inclination angle of the gangway frame 2 so that it can adapt to the use on the ground at different heights.

[0031] Furthermore, a first rotating shaft 4 is provided at both left and right ends of the pedal 3, and the first rotating shaft 4 is rotatably installed on the gangway frame 2. Strip handles 5 are connected to the left and right sides of the gangway frame 2 through adjustable connecting components. The strip handles 5 are arranged in parallel above the gangway frame 2, and the height spacing between the strip handles 5 and the gangway frame 2 can be adjusted through the adjustable connecting component. A box 6 is provided on one side of the gangway frame 2, and a first power adjustment device and a second power adjustment device are respectively provided in the box 6. One end of the first rotating shaft 4 extends into the box 6 and is connected to the first power adjustment device, and the first rotating shaft 4 can be driven to rotate through the first power adjustment device. The lower end of the adjustable connecting component extends into the box 6 and is connected to the second power adjustment device, and the adjustable connecting component can be driven to work through the second power adjustment device so as to adjust the height spacing between the strip handle 5 and the gangway frame 2.

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

[0033] In addition, the first rotating shaft 4 can also be driven to rotate by the first power adjustment device so that the end surfaces of all the pedals 3 are on the same plane (such as Figure 4 As shown), it is convenient for objects with wheels to move on the pedal 3 (such as a bicycle, etc.); at the same time, the pedal 3 can be stored to reduce the overall volume.

[0034] The arrangement of the strip handle 5 makes it convenient for the crew to go up and down the gangway ladder by hand, thereby improving the safety when using the gangway ladder. In addition, the strip handle 5 can adjust the height distance between the strip handle 5 and the gangway ladder frame 2 through an adjustable connecting component, and then the position of the strip handle can be adjusted according to actual usage conditions to make it convenient for the crew to use.

[0035] See also Figure 5As shown, the first power adjustment device includes a first gear 21 provided on the first rotating shaft 4 and located in a box body 6, a first rack 22 that can mesh with the first gear 21 slides in the box body 6, and a first push rod motor 23 for driving the first rack 22 to slide is arranged in the box body 6.

[0036] When the first power adjustment device is working, the first push rod motor 23 drives the first rack 22 to slide, and the first rack 22 is engaged with all the first gears 21, thereby driving all the first rotating shafts 4 and pedals 3 to rotate, thereby achieving the purpose of adjusting the angle of the pedal 3. The structure is simple and the adjustment is convenient.

[0037] See also Figure 1 , Figure 3 , Figure 4 As shown, the adjustable connecting assembly includes a plurality of second rotating shafts 31 rotatably arranged on the gangway frame 2, and connecting rods 32 are arranged on the second rotating shafts 31, and the upper ends of the connecting rods 32 are hinged on the strip handles 5; the strip handles 5 are driven to adjust their positions by swinging the connecting rods 32.

[0038] Furthermore, the second rotating shafts 31 on the left and right sides are connected by the connecting shaft 41, so that the connecting rods 32 on the left and right sides can be connected, and then the connecting rod 32 on one side is driven to swing, and the connecting rod 32 on the other side will also swing accordingly.

[0039] Furthermore, a plurality of the first rotating shafts 4 and a plurality of the second rotating shafts 31 are sequentially arranged at intervals; thus, a connecting rod is arranged between the two pedals 3, which effectively and reasonably utilizes the space.

[0040] See also Figure 5 As shown, the second power adjustment device is connected to include a second gear 51 provided at one end of the second rotating shaft 31 and located in the box body 6, a second rack 52 that can mesh with the second gear 51 slides in the box body 6, and a second push rod motor 53 for driving the second rack 52 to slide is provided in the box body 6.

[0041] When the second power adjustment device is working, the second push rod motor 53 drives the second rack 52 to slide, and the second rack 52 is engaged with all the second gears 51, thereby driving all the second rotating shafts 31 to rotate, and the connecting rod 32 swings, finally achieving the purpose of adjusting the position of the strip handle 5, with a simple structure and convenient adjustment.

[0042] It should be noted that the first gear 21 and the second gear 51 are not located on the same plane, that is, the first gear 21 is arranged a little closer to the inside, and the second gear 51 is arranged a little closer to the outside, so as not to affect the sliding work of the first rack 22 and the second rack 52.

[0043] In order to ensure the stability of the pedal 3 and the bar handle 5 , a locking device capable of locking the first gear 21 and the second gear 51 is further provided in the box body 6 .

[0044] See also Figure 6-Figure 9 As shown, the locking device includes a plurality of first locking holes 71 evenly distributed along the circumference on the end face of the first gear 21, and a plurality of second locking holes 72 evenly distributed along the circumference on the end face of the second gear 51. A plate body 73 is slidable left and right in the box body 6, and a first locking column 74 cooperating with the first locking hole 71 and a second locking column 75 cooperating with the second locking hole 72 are respectively provided at one end of the plate body 73. A guide column 76 is spaced at the outer end of the plate body 73, and the guide column 76 is movably penetrated on the box body 6. A transverse slide groove 77 is provided on the outer side of the plate body 73. A motor 78 is provided in the box body 6, and an L-shaped eccentric column 79 is provided on the output shaft of the motor 78, and one end of the L-shaped eccentric column 79 is movably provided in the transverse slide groove 77.

[0045] When the locking device is in locking operation, the motor 78 drives the L-shaped eccentric column 79 to rotate, and the L-shaped eccentric column 79 moves in the horizontal slide groove 77 and drives the plate body 73 to move, so that 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 bar handle 5; similarly, when unlocking, the first locking column 74 is disengaged from the first locking hole 71, and the second locking column 75 is disengaged from the second locking hole 72, so as to unlock the first gear 21 and the second gear 51.

[0046] It is worth mentioning that since the frequency of adjusting the pedal 3 is higher and the frequency of adjusting the strip handle 5 is lower, in order not to unlock the strip handle 5 when adjusting the pedal 3, the first gear 21 is arranged a little closer to the inside and the second gear 51 is arranged a little closer to the outside, that is, the second gear 51 is closer to the plate body 73. At the same time, the length of the first locking column 74 is shorter than the length of the second locking column 75. Therefore, when the first locking column 74 is disengaged from the first locking hole 71, the second locking column 75 has not yet disengaged from the second locking hole 72, and then the first gear 21 is unlocked and the adjustment operation can be performed, while the second gear 51 is still in a locked state and the adjustment operation cannot be performed.
