[0037] The auxiliary traction mechanism 3 further comprises a fixed frame 31, the fixed frame 31 is fixedly provided with a support arm 32, the support arm 32 is rotatably provided with a winding roller 33, and the top end of the traction rope one 34 is fixedly arranged and wound on the winding roller 33. The support arm 32 is slidingly provided with an extension arm 321, the extension arm 321 is rotatably provided with a guide wheel, and the guide wheel is rollingly arranged with the traction rope one 34. The fixed frame 31 is fixedly provided with a rotating driver two, the output end of the rotating driver two is fixedly arranged with the support arm 32, and the rotation of the output end of the rotating driver two is used for driving the support arm 32 to rotate.

[0038] It should be noted that the rotating driver one 2 comprises but is not limited to a hydraulic motor, the hydraulic motor can generate a large torque, and the rotating speed thereof can be accurately controlled, so that the rotating speed of the gangway can be stably adjusted, the hydraulic system is relatively closed, has a certain adaptability to the salt mist, humidity and other harsh environments on the sea, and has a relatively low failure rate. Moreover, through the circulation lubrication of the hydraulic oil, the wear of the internal components of the motor can be reduced, and the hydraulic motor as a mature prior art will not be described in detail here.

[0039] It should be further noted that the linear driver one 13 comprises but is not limited to a hydraulic cylinder or an electric push rod, the linear driver one 13 can make the pedal two 12 retractable in the pedal one 11 after being started, so as to realize the effect of adjusting the overall length of the combined gangway component 1, and the combination of the pedal one 11 and the pedal two 12 facilitates the adjustment according to the use demand of the personnel.

[0040] Further, the extension arm 321 is slidingly arranged in the support arm 32, and is fixed on the support arm 32 by bolts. The length of the support arm 32 and the extension arm 321 as a whole can be adjusted according to the use requirement, so as to facilitate the traction of the traction rope 34 to the lifting deck 11. The rotating driver 2 and the fixed frame 31 are fixedly installed on the clamping plate of the ship.

[0041] It is worth mentioning that the description of the output end of the rotating driver 2, the driving end of the rotating driver 2 and the output shaft of the rotating driver 2 in the following refers to the same thing.

[0042] The specific implementation scenario is as follows: in the initial state, the deck 11 is horizontally arranged on the ship. When the gangway needs to be lowered for personnel to use, the rotating driver 2 and the rotating driver 2 are started. The rotation of the output end of the rotating driver 2 unwinds the traction rope 34. The rotation of the output end of the rotating driver 2 drives the deck 11 to make a circular motion along the center of the output end of the rotating driver 2. In cooperation with the unwinding of the traction rope 34, the deck 11 is tilted to adjust the attitude of the deck 11. When the deck 11 is adjusted to the required attitude, the output end of the rotating driver 2 and the winding roller 33 are stopped to rotate, thereby ensuring that the deck 11 maintains the corresponding attitude. By arranging the connecting ball head 41 and the fixed seat 42, when the driving end of the rotating driver 2 rotates, the connecting shaft 43 is clamped in the sliding groove 421. The connecting shaft 43 cooperates with the sliding groove 421 to drive the fixed seat 42 to rotate synchronously, so that the rotating driver 2 and the traction rope 34 are adjusted synchronously to adjust the inclination attitude of the deck 11. If the deck 11 is in an inclined state and the sea wave is large at this time, the radial pressure between the deck 11 and the driving end of the rotating driver 2 is generated. Under the cooperation between the sliding groove 421 and the connecting shaft 43, the angle between the deck 11 and the driving end of the rotating driver 2 is deflected, so as to avoid damage between the deck 11 and the driving end of the rotating driver 2 due to the radial force between the deck 11 and the driving end of the rotating driver 2 caused by the fixed arrangement, that is, the deck 11 and the driving end of the rotating driver 2 are not in a vertical state.

[0043] Compared with the prior art, by arranging the connecting ball head 41 and the fixed seat 42, the deck 11 can not only be driven to rotate by the driving end of the rotating driver 2, but also has redundancy between the deck 11 and the driving end of the rotating driver 2 when encountering sea waves. The deck 11 and the driving end of the rotating driver 2 do not need to be always kept in a vertical state. Even if the wind wave generates an axial force on the output end of the rotating driver 2 through the deck 11, it can also ensure that the output end of the rotating driver 2 and the connecting part between the deck 11 and the output end of the rotating driver 2 are uniformly stressed, so as to avoid mechanical stress to cause deformation or damage of the components, ensure the accuracy and service life of the driver, improve the stability and safety of the gangway angle adjustment, and eliminate the risk of ship operation.

[0044] Referring to the drawings Figure 6 When the staff stands on the inclined pedal one 11, there may still be wind waves in the process of rotating the pedal one 11 back to the original position, even if the damage to the components caused by the radial force can be avoided between the connecting ball head 41 and the fixed seat 42, but the existence of wind waves may cause the pedal one 11 to shake in the radial direction of the output end of the rotating driver one 2 during the resetting process, and the shaking of the pedal one 11 may cause hidden dangers to the safety of the staff. In order to avoid the above situation, specifically, the combined gangway component 1 is also provided with an anti-collision mechanism 5, the anti-collision mechanism 5 includes a traction hook two 52, the traction hook two 52 is fixedly arranged on the combined gangway component 1, the traction rope two 51 is fixedly arranged on the traction hook two 52, and the traction rope two 51 is arranged on the combined gangway component 1 in an inclined manner. The top end of the traction rope two 51 is fixedly provided with a traction machine.

[0045] It should be noted that the traction machine is fixedly installed on the ship, and the length of the traction arm of the traction machine is less than the distance between the traction machine base and the side of the pedal one 11, that is, when the traction machine is traction pedal one 11, the traction rope two 51 is in the state shown in Figure 6 , because the traction force of the traction rope two 51 is located on the right side of the pedal one 11, the traction rope two 51 can assist in adjusting the posture of the pedal one 11 during the process of traction and lifting the pedal one 11, so that the pedal one 11 is slowly reset against the ship side wall. The guidance of the traction direction of the pedal one 11 can avoid the left and right shaking of the pedal one 11 caused by the radial force of the output end of the rotating driver one 2.

[0046] Referring to the drawings Figure 6 With Figure 7 , in the process of rotating the pedal one 11 back to the original position, the traction rope two 51 provides a one-way auxiliary tension for the pedal one 11, avoiding the shaking of the pedal one 11, but the side of the pedal one 11 will contact the ship body, in order to avoid damage to the ship body, specifically, the anti-collision mechanism 5 further includes a linear driver two 53, the linear driver two 53 is fixedly arranged on the pedal one 11, a support seat 531 is fixedly arranged on the output end of the linear driver two 53, and a roller 54 is rotatably arranged on the support seat 531. A sliding groove is formed in the support seat 531, an adjusting seat one 55 and an adjusting seat two 56 are slidably arranged in the sliding groove, and an elastic member 57 is arranged between the adjusting seat one 55 and the adjusting seat two 56. A fixed shaft is fixedly arranged on the roller 54 and slidably arranged in the sliding groove. The fixed shaft is in contact with the adjusting seat one 55, a pressure sensor 58 is fixedly arranged on the support seat 531, and the collection end of the pressure sensor 58 is in contact with the adjusting seat two 56.

[0047] It should be noted that the elastic member 57 is provided as a spring, and the two ends of the spring are fixedly arranged on the side of the adjusting seat one 55 and the adjusting seat two 56 close to each other. The linear driver two 53 includes but is not limited to a hydraulic cylinder or a push rod motor, and a plurality of linear driver two 53 are arranged on the pedal one 11, and a plurality of rollers 54 and other related components are arranged on the output end of the linear driver two 53, that is, the linear driver two 53 is provided with a plurality of groups. The collection end of the pressure sensor 58 is caused by the pressure change of the measured object to change the inductance of the inductor coil, so as to obtain the pressure parameter of the roller 54, and the working principle thereof is mature existing technology and will not be described in detail here.

[0048] It should be further noted that when the traction rope one 34 and the traction rope two 51 lift the pedal one 11 to reset, the linear driver two 53 is started, the movement of the output end of the linear driver two 53 drives the roller 54 to contact the hull of the ship, and the roller 54 provides a reaction force for the adjusting seat one 55 after contacting the hull of the ship. The reaction force will push the adjusting seat two 56 to move towards the collection end of the pressure sensor 58 through the elastic member 57, and the collection end of the pressure sensor 58 obtains the pressure parameter. More accurately, when the collection end of the pressure sensor 58 obtains the pressure of 300N feedback by the roller 54, it is not necessary to adjust the position of the output end of the linear driver two 53, if the pressure sensor 58 receives the pressure feedback by the roller 54 is less than the value, the output end of the linear driver two 53 drives the support seat 531 to move towards the hull of the ship, ensures that the rollers 54 on the output ends of the plurality of linear driver two 53 can be attached to the hull of the ship, and makes the posture of the pedal one 11 reset more stably, further improves the safety of the staff on the pedal one 11.

[0049] Further, through the cooperation of the linear driver two 53 and the roller 54, not only can provide support between the pedal one 11 and the hull of the ship, ensure that the pedal one 11 maintains a stable posture during the process of rotating reset, and because the inclination of the side of the ship hull is not the same, through the cooperation of the pressure sensor 58 and the elastic member 57 and other components, the distance between the roller 54 and the ship hull can be adaptively adjusted according to the change of the different height inclination of the ship hull, so as to ensure that the distance between the pedal one 11 and the ship hull is always the same, thereby further improving the stability of the pedal one 11 during the posture reset process.

[0050] The working principle is that, in the initial state, the pedal 11 is horizontally arranged on the ship, when the gangway needs to be lowered for personnel to use, the rotating driver 2 and the rotating driver 2 are started, the rotating driver 2 output end releases the traction rope 34, the rotating driver 2 output end of the rotating driver 2 output end makes a circular motion along the center of the rotating driver 2 output end, cooperates with the release of the traction rope 34, realizes the effect of tilting the pedal 11 and adjusting the posture of the pedal 11, when the pedal 11 is adjusted to the required posture, the output end of the rotating driver 2 is stopped rotating around the winding roller 33, thereby ensuring that the pedal 11 maintains the corresponding posture. By arranging the connecting ball head 41 and the fixed seat 42, when the driving end of the rotating driver 2 rotates, the connecting shaft 43 is clamped in the sliding groove 421, the connecting shaft 43 cooperates with the sliding groove 421 to drive the fixed seat 42 to rotate synchronously, so that the rotating driver 2 and the traction rope 34 are synchronized to adjust the inclined posture of the pedal 11. If the pedal 11 is in an inclined state and the sea wave is large at this time, the radial pressure between the pedal 11 and the driving end of the rotating driver 2 is generated, under the cooperation between the sliding groove 421 and the connecting shaft 43, the angle between the pedal 11 and the driving end of the rotating driver 2 is deflected, which avoids the damage caused by the radial force between the pedal 11 and the driving end of the rotating driver 2 due to the fixed arrangement, that is, the pedal 11 and the driving end of the rotating driver 2 are not in a vertical state. The traction machine is fixedly installed on the ship, and the length of the traction machine traction arm is less than the distance between the traction machine base and the side of the pedal 11, that is, when the traction machine is traction pedal 11, the traction rope 52 is like Figure 6As shown in the state in the middle of FIG. 6, because the traction force of the traction rope two 51 is located at the right side of the step one 11, the traction rope one 34 can assist in adjusting the posture of the step one 11 in the process of traction lifting the step one 11, so that the step one 11 is slowly reset against the ship side wall, and the traction direction of the step one 11 is guided to avoid the step one 11 from being shaken left and right by the radial force of the output end of the rotation driver one 2. When the traction rope one 34 and the traction rope two 51 lift the step one 11 to reset, the linear driver two 53 is started, the moving drive roller 54 at the output end of the linear driver two 53 is in contact with the hull of the ship, and when the roller 54 is in contact with the hull of the ship, the adjusting seat two 56 will be provided with a reaction force, the reaction force will push the adjusting seat two 56 to move towards the collection end of the pressure sensor 58 through the elastic member 57, and the collection end of the pressure sensor 58 obtains the pressure parameter. More accurately, when the collection end of the pressure sensor 58 obtains the pressure of 300N fed back by the roller 54, it is not necessary to adjust the moving position of the output end of the linear driver two 53, if the pressure sensor 58 receives the pressure fed back by the roller 54 less than the value, the output end of the linear driver two 53 drives the support seat 531 to move towards the hull of the ship, so that the rollers 54 on the output ends of the plurality of linear driver two 53 can be attached to the hull of the ship, so that the posture of the step one 11 is reset more stably, and the safety of the staff on the step one 11 is further improved.

[0051] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application.
