[0001] The present invention relates to the technical field of ship fall protection, and in particular to a ship boarding and disembarking fall protection device with a lifting function and an integral rescue mechanism. Background Art

[0002] Currently, when a ship is not docked, there are two main ways for staff to board and disembark: one is to use a transport vessel to transport personnel from the port to the side of a large ship, and then climb the pilot ladder on the side of the ship to board or disembark; the other is to use a helicopter to transport boarding personnel from the port to the deck of a large ship, and then bring the disembarking personnel back to the port.

[0003] During the process of boarding and disembarking a ship via a pilot ladder, workers need to climb a long distance of the boarding ladder by hand. Especially in severe weather conditions such as wind, waves, rain and snow, the risk of falling increases significantly. However, the existing types of fall arresters on the market are mainly used for fixed-point operations. They cannot provide adequate protection when dealing with the up and down movement operations when boarding and disembarking a ship via a pilot ladder, and are not suitable for the special environment and specific operating requirements of ship operation.

[0030] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] According to an embodiment of the present invention, a fall protection device for embarking and disembarking a vessel with a lifting function and an integral rescue mechanism is provided.

[0032] Please refer to the instruction manual Figure 1-8According to an embodiment of the present invention, a fall protection device for boarding and leaving a ship with a lifting function and an integral rescue mechanism includes a lower bracket 1, which is mounted on the inner side of a railing at the upper end of the deck. The upper end of the lower bracket 1 is rotatably connected to an upper bracket assembly 2, a seat plate 3 is mounted on the outer wall of the upper end of the lower bracket 1, and an anti-fall assembly 4 is mounted on the outer wall of the seat plate 3; the anti-fall assembly 4 includes a shell 5, which is mounted on the outer wall of the seat plate 3, and a first central shaft 6 is rotatably mounted in the shell 5, and a speed differential anti-fall device is mounted on the first central shaft 6. 7, one end of the first central axis 6 is provided with a matching hole, and the end passes through the front wall of the shell 5 and a rocker 8 is installed in the matching hole. The speed differential anti-falling device 7 is used in conjunction with the anti-falling device control mechanism 9 installed in the inner cavity of the shell 5. A part of the speed differential anti-falling device 7 can be engaged with a part of the rescue component 10 for transmission; the rescue component 10 includes a second central axis 11, which is rotatably installed in the inner cavity of the shell 5. One end of the second central axis 11 is also provided with a matching hole, and the end passes through the front wall of the shell 5 and the matching hole can also be engaged. To cooperate with the rocker 8, the limiting rod 13 and the shift rod 14 both pass through the side wall of the housing 5. A limiting groove 12 is provided on the second central axis 11. The limiting groove 12 is used in conjunction with the limiting rod 13. The limiting rod 13 is an axial limiting mechanism of the second central axis 11. When the second gear 15 is engaged and disengaged, the two limiting grooves 12 on the second central axis 11 are respectively inserted to limit the axial free movement of the second central axis 11. The second central axis 11 can also be used in conjunction with the shift rod 14. A second gear is installed on the second central axis 11. 15, the second gear 15 can be engaged with a part of the speed differential anti-fall device 7 for transmission, and a pressure block 16 is installed on the second central shaft 11 on the rear side of the second gear 15, and a friction block 18 is installed on the rear side of the pressure block 16. A locking ratchet 17 is installed at the rear of the friction block 18, and a friction block 18 is also installed at the rear of the locking ratchet 17, and a stopper 26 is installed at the rear of the friction block 18. The locking ratchet 17 cooperates with the locking pawl 19 to form a locking mechanism, and the locking pawl 19 is installed on the rear outer wall of the housing 5.

[0033] Among them, the contact part between the inner ring of the second gear 15 and the second central axis 11 is a threaded structure. When the first gear 73 reverses, the second gear 15 will press against the pressure block 16 along the surface thread of the second central axis 11, thereby pressing the friction block 18 and the locking ratchet 17, so that the second gear 15, the locking ratchet 17 and the second central axis 11 are integrated. The locking pawl 19 is inserted into the teeth of the locking ratchet 17, which limits the reversal of the locking ratchet 17, thereby preventing the first gear 73 and the rope hub 71 from rotating, and finally preventing the safety rope 22 from sliding down and people from falling.

[0034] In one embodiment, please refer to the appendix of the specification. Figure 1-6As a further solution of the present invention, the speed differential anti-fall device 7 includes a rope hub 71, which is mounted on the first central axis 6. A coil spring 72 is built into the center of the rope hub 71. A first gear 73 is mounted on the first central axis 6 on the rear side of the rope hub 71. A first ratchet 74 is mounted on the first central axis 6 on the rear side of the first gear 73. A second ratchet 75 used in conjunction with the first ratchet 74 is mounted on the first central axis 6 on the front side of the rope hub 71. A pawl device 76 used in conjunction with the first ratchet 74 and the second ratchet 75 is mounted below the first ratchet 74 and the second ratchet 75. Bearings 20 and a first sleeve 21 are mounted on both ends of the first central axis 6, respectively. The first gear 73 can be meshed with the second gear 15 for transmission, and the two gears can be engaged or disengaged, which is achieved by the axial movement of the second central axis 11 by the shift lever 14. The pawl device 76 includes a rotating shaft 761, and the rotating shaft 761 is rotatably installed in the inner cavity of the outer shell 5. A double pawl 762 is installed on the rotating shaft 761, and the two ends of the double pawl 762 are respectively used in conjunction with the first ratchet 74 and the second ratchet 75. One end of a pawl tension spring 763 is installed on the inner wall of one end of the double pawl 762, and the other end of the pawl tension spring 763 is installed on the inner wall of the outer shell 5 through a pillar. One end of the double pawl 762 is used in conjunction with the anti-fall device control mechanism 9. When in use, the double pawl 762 cooperates with the first ratchet 74 and the second ratchet 75 to realize the speed differential anti-fall function. When the safety rope 22 falls rapidly, the double pawl 762 will quickly insert into the teeth of the first ratchet 74 and the second ratchet 75, thereby locking the rope hub 71, so that the safety rope 22 wrapped around the rope hub 71 stops continuing to slide down, thereby realizing the anti-fall function.

[0035] The coordination between the double pawl 762, the first ratchet 74, and the second ratchet 75 is as follows: when the safety rope 22 is rapidly descending, the counterclockwise rotating ratchet teeth will rapidly impact end b of the double pawl 762, causing end b to rotate about the rotation axis 761 to position b1. Simultaneously, end a of the double pawl 762 rotates to position a1, where it inserts into the teeth of the first and second ratchet wheels 74, 75, thereby locking the counterclockwise rotation of the first and second ratchet wheels 74, 75. When the safety rope 22 is slowly descending, the double pawl 762 is pulled by the pawl tension spring 763, keeping end b of the double pawl 762 in constant contact with the ratchet teeth. End a of the double pawl 762 will not insert into the ratchet teeth, thus preventing the slow descent of the safety rope 22.

[0036] The coil spring 72 can automatically retract the safety rope 22 and wind it around the rope hub 71 in the absence of external force.

[0037] In one embodiment, please refer to the appendix of the specification. Figure 1-4 and Figure 8As a further solution of the present invention, the fall arrester control mechanism 9 includes a release rod 91, which is located on one side of the end of the pawl tension spring 763 in the double pawl 762, and a locking rod 92 is installed on the other side of the double pawl 762. One end of the release rod 91 and the locking rod 92 are both installed with a rod tension spring 93, and the other end of the release rod 91 is installed with a release cable 94, and the bottom end of the release cable 94 passes through the bottom wall of the shell 5 and is connected to the release foot pedal 25. The other end of the locking rod 92 is installed with a locking cable 95, and the bottom end of the locking cable 95 passes through the bottom wall of the shell 5 and is connected to the locking foot pedal 27. By operating the release cable 94 or the locking cable 95 by stepping on the release pedal 25 or the locking pedal 27, the release rod 91 and the locking rod 92 can control the rotation or limiting of the double pawl 762, thereby achieving the locking or inability to lock the pawl and the ratchet, realizing the state control of the speed differential anti-fall device 7, and matching the requirements of various boarding and disembarking processes.

[0038] In one embodiment, please refer to the appendix of the specification. Figure 7 and Figure 8 As a further embodiment of the present invention, the upper support assembly 2 includes a rotatable upper cantilever support 201, which is rotatably mounted on the upper end of the lower support 1. A guide pulley 202 is mounted on the outer wall of the rotatable upper cantilever support 201. A safety rope 22 is passed through the guide pulley 202. One end of the safety rope 22 is wrapped around the rope hub 71, and a drop buffer 23 is mounted on the other end of the safety rope 22. A safety hook 24 is mounted on the bottom end of the drop buffer 23. During use, the rotatable upper cantilever support 201 is rotated so that the cantilever end is directly above the boarding ladder or boarding gate. The guide pulley 202 guides the safety rope 22 to this position, and the safety rope 22 is vertically lowered to facilitate use by personnel boarding and disembarking. The drop buffer 23 can reduce the impact on personnel when the fall is locked. The safety hook 24 is attached to the safety belt behind the climber when in use, making it convenient to use.

[0039] Working process: When the pilot needs to board the ship, the operator of the protective device first adjusts the cantilever end of the rotatable upper cantilever bracket 201 to the position above the pilot ladder, and then unlocks the speed differential anti-fall device 7 by stepping on the release pedal 25 to drive the release cable 94, and then rotates the rope hub 71 through the rocker 8 to lower the safety rope 22 and the safety hook 24 to the required position. After that, the pilot hooks the safety rope 22 to the safety belt on the back, and the operator pulls out the rocker 8. At this time, in order to avoid the speed differential anti-fall device 7 from being suddenly locked due to the large ups and downs of the ship, the operator still steps on the release pedal 25 to drive the release cable 94 to put the speed differential anti-fall device 7 in a free state. When the pilot climbs to the first step of the pilot ladder, he releases the release pedal 25 and the release cable 94 to put the speed differential anti-fall device 7 into a standby state for fall protection. During the process of the pilot climbing the pilot ladder, due to the speed differential anti-fall device The coil spring 72 built into the rope hub 71 in 7 allows the safety rope 22 to automatically move with the climber. During this process, if the climber falls accidentally during the climbing process and the safety rope 22 drops rapidly, the double pawl 762 will quickly insert into the teeth of the first ratchet 74 and the second ratchet 75, thereby locking the rope hub 71 and stopping the safety rope 22 wound around the rope hub 71 from continuing to slide down, thereby realizing the anti-fall function and making the person suspended in the air. The operator then removes the rocker 8 and installs it on the second central shaft 11 in the rescue component 10, and then pushes the dial rod 14 to make the second central shaft 11 move axially, thereby making the second gear 15 engage with the first gear 73, and then rotates the rocker 8 to drive the first gear 73 to rotate through the second central shaft 11 and the second gear 15, thereby driving the rope hub 71 to rotate, retracting or releasing the safety rope 22, so that the suspended person can rise or fall to a safe position. During this process, the second central shaft 11 and the attached second gear 15, locking ratchet 17, locking pawl 19, pressure block 16, friction block 18, stop block 26 and other components can ensure that no sudden fall occurs during the process of lifting or lowering a fallen person.

[0040] When the pilot needs to disembark, the procedure for disembarking via the pilot ladder is basically the opposite, and the fall protection device also protects the safety of personnel leaving the ship.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
