[0034] When there is an offset between the lever 410 and the corresponding slot 408, one of the multiple infrared signal receivers 411 will not receive the signal from the infrared signal transmitter 409, and thus will not be able to transmit the signal to the controller 412.

The control principle is a basic programming CNC control method known to those skilled in the art. It can be achieved by CNC programmers editing the corresponding control value program. These are all conventional methods or common knowledge, and will not be described in detail here.
[0035] A support and stabilizing mechanism 2 is installed on the top right side of the main body 1 of the telescopic boarding ladder. The support and stabilizing mechanism 2 includes a support overlap platform 201 rotatably installed on the top right side of two support plates 101 at the front and rear. Support blocks 202 are fixedly connected to the top right side of the two support plates 101 at the front and rear sides. Pins are fixedly connected to the left front side and the left rear side of the support overlap platform 201. Circular holes are opened on the front and rear sides of the support blocks 202. A first bearing is fixedly sleeved in the circular hole. The inner side of the inner ring of the first bearing is fixedly connected to the outer side of the corresponding pin. The first bearing and the pin cooperate to achieve the effect of allowing the support overlap platform 201 to be rotatably installed.
[0036] Furthermore, the power supply for the hydraulic cylinder 401, the brake motor 404, the infrared signal transmitter 409, and the multi-stage push rod motor 3 can be directly supplied through the power lines connected to the offshore platform 6. This invention, through a series of structural designs, can fix the entire device on the offshore platform 6, eliminating the need to install wave-compensation personnel boarding ladders on each vessel. Compared to the existing method of installing wave-compensation personnel boarding ladders on each vessel, this significantly reduces costs. It also allows for adjustment of the tilt angle, orientation angle, and length of the telescopic boarding ladder body 1, using its controlled movement to compensate for the target vessel's movement, thus facilitating personnel use. Additionally, after adjusting the orientation angle of the telescopic boarding ladder body 1, multiple locking rods 410 can be used to securely fix it, and the supporting and stabilizing mechanism 2 further supports and fixes the other side of the telescopic boarding ladder body 1, effectively improving stability during use.
[0037] Working principle: When in use, the entire wave compensation function personnel boarding gangway body can be fixed on the offshore platform 6 by the cooperation of the mounting base 5 and the T-shaped fixing bolt 501. This method of installation on the offshore platform 6 eliminates the need to install the wave compensation function personnel boarding gangway body on each ship. Compared with the existing technology of installing the wave compensation function personnel boarding gangway body on each ship, its cost is significantly reduced.
[0038] At this time, the telescopic boarding gangway body 1 is in an inclined and raised state. When adjusting the tilt angle of the telescopic boarding gangway body 1 according to the position of the ship 7, the top position of the ship 7 is higher than the position of the offshore platform 6. The two hydraulic cylinders 401 can be opened in reverse by the second synchronous control switch. The output shaft of the hydraulic cylinder 401 pulls the telescopic boarding gangway body 1 to rotate downward. When the telescopic boarding gangway body 1 drives the support and stabilization mechanism 2 to rotate downward until it is level with or in contact with the top of the target ship, the two hydraulic cylinders 401 can be closed. When there is a certain distance between the support and stabilization mechanism 2 and the target ship, the two multi-stage push rod motors 3 can be opened in the forward direction. The output shafts of the two multi-stage push rod motors 3 simultaneously drive the two front and rear support plates 101 to move away from the support box 402 through the connecting plate 105. The two support plates 101 drive the corresponding multiple stepped platforms 102 to move to the right. At the same time, the two support plates 101 at the front and rear also drive the support stabilizing mechanism 2 to move to the right. When it reaches the top of the target ship, the two multi-stage push rod motors 3 can be turned off. At this time, the support connecting platform 201 is rotated and moved to be flush with the top of the target ship. The support connecting platform 201 can support the right side of the adjusted telescopic boarding gangway body 1, improving the stability during use. When the ship 7 is raised or lowered by waves, the support connecting platform 201 can rotate up and down with the ship 7, thereby achieving the effect of wave compensation. In addition, the tilt angle of the telescopic boarding gangway body 1 can be adjusted so that the telescopic boarding gangway body 1 can be tilted and raised after use, reducing the lateral space occupied.
[0039] Additionally, when adjusting the telescopic boarding gangway body 1, if there is an offset in the orientation angle between the telescopic boarding gangway body 1 and the ship 7, the personnel first drive the two miniature electric telescopic rods 405 to open synchronously in the opposite direction via the first synchronous control switch 413. The output shaft of the miniature electric telescopic rod 405 drives multiple locking rods 410 to move out of their corresponding locking slots 408 through the ring 407, releasing the fixation on the support box 402. At this time, the brake motor 404 can be activated. The output shaft of the brake motor 404 drives the support box 402 to rotate, and the support box 402 passes through... The rotating roller 403 drives the telescopic boarding gangway body 1 to rotate, causing its orientation angle to change. When the orientation angle of the telescopic boarding gangway body 1 is aligned with the orientation of the ship 7, the brake motor 404 can be stopped. Then, the two miniature electric telescopic rods 405 are opened in the forward direction, causing multiple locking rods 410 to move downwards and insert into their corresponding slots 408. If there is a misalignment between the locking rod 410 and the corresponding slot 408, one of the multiple infrared signal receivers 411 will not receive the signal from the infrared signal transmitter 409. Unable to transmit a signal to the controller 412, if the controller 412 does not receive a signal 3 seconds after the brake motor 404 is closed, it will control the brake motor 404 to open again to rotate and drive multiple levers 410. The levers 410 drive the corresponding infrared signal receivers 411 to rotate. When one of the infrared signal receivers 411 aligns with the infrared signal transmitter 409, the infrared signal receiver 411 transmits a signal to the controller 412. The controller 412 then controls the brake motor 404 to close and controls the two... When the miniature electric telescopic rod 405 is opened in the forward direction, the locking rod 410 drives the corresponding infrared signal receiver 411 to insert into the slot 408. The locking rod 410 and the corresponding slot 408 are engaged. By using the combined force of multiple locking rods 410 and multiple slots 408, the support box 402 is fixed, thereby fixing the orientation angle of the telescopic boarding ladder body 1. Furthermore, the fixing method improves the stability of the telescopic boarding ladder body 1, effectively reducing its displacement during use and improving stability during use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
