After the sliding adjustment, the locking plate 32 is moved downward to reinsert the locking groove 302 into the locking tooth 301 to complete the locking.

[0026] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , guardrails 43 are installed on both sides of the top of the pedal 4; It should be noted that when climbing up the ladder 6 and standing on the step 4, the guardrail 43 is used for climbing protection to improve the safety of boarding.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 6 The driving member 5 includes a rack plate 51, and the rack plate 51 is provided with two groups. The two groups of rack plates 51 are symmetrically mounted at the bottom end of the pedal 4. A driving motor 52 is mounted on the sliding block 2. A transmission rod 53 is fixedly mounted on the output shaft of the driving motor 52. A gear 54 is symmetrically mounted on the transmission rod 53. The gear 54 is meshed with the corresponding rack plate 51. It should be noted that: when the driving member 5 is in use, when it is necessary to adjust the distance between the pedal 4 and the base plate 1 so that the ladder 6 is closer to the port, the driving motor 52 is started, the driving motor 52 drives the transmission rod 53 to rotate, and the transmission rod 53 drives the two gears 54 to rotate. When the gears 54 rotate, they engage with the rack plate 51, thereby driving the pedal 4 to slide along the T-block 21 of the sliding block 2 to achieve distance adjustment.

[0028] In the embodiments of the present invention, please refer to Figure 1 and Figure 4The bottom end of the pedal 4 is provided with an auxiliary support member 9, and the auxiliary support member 9 includes a lead screw 91, the lead screw 91 is rotatably mounted on the bottom end of the pedal 4, and a hanging plate 92 is threadedly connected to the lead screw 91, and a support rod 93 is rotatably mounted on the bottom end of the hanging plate 92, and a plurality of support wheels 94 are evenly mounted on the support rod 93, and the hanging plate 92 is slidably matched with the pad 41; It should be noted that: after the pedal 4 is adjusted, in order to make its support more stable, the screw 91 is rotated to drive the suspension plate 92 to slide along the pad 41, thereby adjusting the support position of the bottom support rod 93 and the support wheel 94 to make it dock with the deck of the engineering ship, thereby improving the support strength of the pedal 4; In the present embodiment, hexagonal countersunk holes are provided at both ends of the lead screw 91, so that when the lead screw 91 is driven to rotate, the lead screw 91 can be driven to rotate by driving the operating rod of the hexagonal head into the hexagonal countersunk hole.

[0029] The working principle of the engineering ship boarding ladder provided by the present invention is as follows: When in use, after the base plate 1 is connected to the deck of the engineering ship by using the threaded through hole, when it is necessary to get on or off the ship, the locking piece 3 is released from the lock of the sliding block 2, and then the sliding block 2 is pulled to slide along the T-shaped boss 11, driving the pedal 4 to slide synchronously, thereby adjusting the position of the ladder 6 installed on the pedal 4 to dock with the passage of the port. After docking, when it is necessary to adjust the angle, the rotary motor 42 is controlled to drive the connecting rod 7 to rotate, so as to adjust the placement angle of the ladder 6. When it is adjusted to a point that is not suitable for standing and climbing, the ladder plate mechanism 8 is controlled to fill the gap of the ladder 6, so that it is convenient to walk directly on the ladder 6 to board the ship, making it more convenient to get on or off the ship. When the ladder plate mechanism 8 is in use, when it is necessary to walk on the ladder 6, the electric telescopic rod 81 is controlled to drive the support frame 82 to move the horizontal plate 83 to the gap between the ladder bars of the ladder 6 to complete the gap filling of the ladder 6. It should also be noted that when the ladder 6 is in a vertical state, in order to prevent other people from stealing the ladder 6, the horizontal plate 83 can be used to fill the gap of the ladder 6 to prevent other people from stealing and improve the safety of the ladder 6. When the driving member 5 is further configured for use, when it is necessary to adjust the distance between the pedal 4 and the base plate 1 so that the ladder 6 is closer to the port, the driving motor 52 is started, and the driving motor 52 drives the transmission rod 53 to rotate, and the transmission rod 53 drives the two gears 54 to rotate. When the gear 54 rotates, it engages with the rack plate 51, thereby driving the pedal 4 to slide along the T-block 21 of the sliding block 2 to achieve distance adjustment. After the pedal 4 is adjusted, in order to make its support more stable, the screw 91 is rotated to drive the suspension plate 92 to slide along the pad 41, thereby adjusting the support position of the bottom support rod 93 and the support wheel 94, so that it is docked with the deck of the engineering ship, thereby improving the support strength of the pedal 4.
