[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 7A ship outfitting chain-type soft ladder includes two chain ropes 1, a plurality of fixed plates 101 are fixedly connected between the two chain ropes 1, and a plurality of fixed components 2 are rotatably connected to one end of the fixed plate 101. The fixed component 2 includes a piston rod 201 rotatably connected to the fixed plate 101, and a piston cylinder 202 is provided on the outer surface of the piston rod 201. A suction cup 203 is provided on the side of the piston cylinder 202 away from the fixed plate 101. The piston cylinder 202 and the piston rod 201 can be replaced with piston cylinders 202 and piston rods 201 of different lengths to adapt to ships with different inclinations of the outer wall;

[0036] The interior of the suction cup 203 is connected to the interior of the piston cylinder 202 through a hose 206. A pedal 102 is provided between the two chain ropes 1. The number of pedals 102 is the same as the number of fixed plates 101, and each pedal 102 is located on the upper side of its corresponding fixed plate 101. The lower end of the pedal 102 is rotatably connected to a plurality of pushing components 3. The pushing components 3 are used to push the piston cylinder 202 to move. The pushing components 3 can be replaced with a rigid rod with adjustable length to cooperate with piston cylinders 202 and piston rods 201 of different lengths.

[0037] The pushing component 3 is a support rod 301 rotatably mounted on the lower end of the pedal 102 , and one end of the support rod 301 away from the pedal 102 is rotatably connected to the outer wall of the piston cylinder 202 .

[0038] By adopting the above technical solution, when in use, the user steps on the pedal 102 and the pedal 102 can be lowered relative to the chain rope 1. At this time, since the fixed plate 101 is fixedly installed on the chain rope 1, the pedal 102 can be lowered relative to the fixed plate 101. After the pedal 102 is lowered relative to the fixed plate 101, it can push the upper end of the support rod 301. When the upper end of the support rod 301 is pushed, since the length of the support rod 301 is fixed and the other end of the support rod 301 is connected to the piston cylinder 202, the upper end of the support rod 301 can be rotated under the decomposition force of the extrusion force after being pushed. After the support rod 301 rotates, its lower end can push the connection point between it and the piston cylinder 202, thereby causing the piston cylinder 202 to move. After the piston cylinder 202 moves, it can move relative to the piston rod 201. At this time, since the piston rod 201 is relatively After the piston cylinder 202 moves relative to each other, the air pressure in the piston cylinder 202 can be reduced. After the pressure in the piston cylinder 202 is reduced, the air in the suction cup 203 can enter the inside of the piston cylinder 202 through the hose 206, thereby reducing the air pressure inside the piston cylinder 202. When the pressure in the suction cup 203 is reduced, the suction cup 203 can fit tightly against the outer wall of the hull, thereby reducing the swing amplitude of the chain rope 1 when the staff is climbing, making it easier and safer for the staff to climb. Among them, the piston cylinder 202 after moving relative to the piston rod 201 can increase the distance between the suction cup 203 and the fixed plate 101. At this time, the distance between the fixed plate 101 and the outer wall of the hull will also increase, so that the device is in an inclined state instead of being perpendicular to the horizontal plane, which is more conducive to the staff to climb.

[0039] A return spring 204 is fixedly mounted on one end of the piston rod 201 close to the suction cup 203 , and the other end of the return spring 204 is fixedly connected to the inner wall of the piston cylinder 202 . A magnet 205 is embedded in the inner wall of the suction cup 203 .

[0040] By adopting the above technical solution, when the device is lowered from the ship, the magnet 205 can fit with the hull under the action of its own magnetic force, so that the suction cup 203 fits with the hull, wherein, through the set return spring 204, when the staff member's foot leaves the pedal 102 and no longer steps on the pedal 102, the return spring 204 pulls the piston cylinder 202 to move it to the initial position, thereby causing the piston cylinder 202 to move relative to the piston rod 201 again. When the piston cylinder 202 moves to the initial position, the pressure inside the piston cylinder 202 will gradually approach the atmospheric pressure. When the pressure in the piston cylinder 202 returns to normal, the suction cup 203 will no longer generate suction on the hull, and will only rely on the magnet 205 to fit on the hull, making it convenient for subsequent staff to retract the device from the outside of the hull to the ship.

[0041] A plurality of guide grooves 103 are formed on the upper end of the pedal 102. A clamping assembly 4 is installed inside the guide grooves 103. The clamping assembly 4 is used to fix the user's foot. The clamping assembly 4 includes a guide block 401 slidably installed inside the guide groove 103. An extrusion block 402 is fixedly installed on the upper end of the guide block 401. The end of the extrusion block 402 away from the chain 1 has an arc-shaped structure, and a friction pad 403 is fixedly installed on the arc portion of the extrusion block 402.

[0042] A guide rod 404 is fixedly installed at one end of the guide block 401, and a piston cavity 104 is opened on the inner wall of the guide groove 103 near the end of the guide rod 404. The guide rod 404 is slidably connected to the piston cavity 104, and the direction of the guide rod 404 is the same as the direction of the guide groove 103. A plurality of driving components 5 are provided between the lower end of the pedal 102 and the upper end of the fixed plate 101. The driving component 5 is used to push the guide rod 404 to move. The driving component 5 includes a bellows 501 fixedly installed on the upper end of the fixed plate 101, and a ventilation pipe 502 is penetrated through the outer wall of the bellows 501. One end of the ventilation pipe 502 is communicated with the interior of the bellows 501, and the other end of the ventilation pipe 502 passes through the pedal 102 and is communicated with the interior of the piston cavity 104.

[0043] By adopting the above technical solution, when the pedal 102 is stepped on by the staff, the pedal 102 descends relative to the fixed plate 101 to squeeze the bellows 501, causing the bellows 501 to contract. After the bellows 501 contracts, the pressure inside the bellows 501 can be increased. After the air pressure inside the bellows 501 increases, part of the air can enter the piston cavity 104 through the vent pipe 502. When the air enters the piston cavity 104, the air pressure in the piston cavity 104 can be increased. At this time, under the action of the air pressure, the guide rod 404 can move relative to the piston cavity 104. After the guide rod 404 moves, it can drive the guide block 401 to move. At this time, The guide block 401 can drive the squeezing block 402 to move along the direction of the guide groove 103. At this time, the two squeezing blocks 402 close to each other can squeeze the feet of the staff, and the squeezing blocks 402 can be located in the concave parts in the middle of both sides of the staff's shoes after moving, which can fix the staff's feet and prevent the staff's feet from slipping to the sides during the climbing process, thereby ensuring the safety of the staff when climbing. Among them, the friction pad 403 can play an anti-slip role, and together with the squeezing block 402, it can also prevent the staff's feet from slipping back and forth, further ensuring the safety of the staff during climbing.

[0044] A pressure spring 405 is fixedly mounted on one end of the guide block 401 away from the guide rod 404, and the other end of the pressure spring 405 is fixedly connected to the inner wall of the guide groove 103;

[0045] A plurality of rubber blocks 105 are fixedly mounted on the upper end of the pedal 102. The interior of the rubber block 105 is a hollow structure. A cavity 106 is provided inside the pedal 102 at a position corresponding to the rubber block 105. The hollow portion inside the rubber block 105 is connected to the interior of the cavity 106. An air groove 107 is provided on one side of the piston chamber 104, and the other end of the air groove 107 is connected to the interior of the cavity 106.

[0046] By adopting the above technical solution, when the staff gradually climbs, the feet are lifted up and move away from the two extrusion blocks 402, and the pressure applied by the staff to the pedal 102 will gradually decrease. At this time, the pressure spring 405 can squeeze the guide block 401, so that the guide block 401 moves to the initial position, thereby restoring the extrusion block 402 to the initial position for the next use. When the staff steps on the pedal 102, the rubber block 105 will be embedded in the gap of the staff's sole. When the staff steps on the pedal 102 to allow the air in the bellows 501 to enter the piston chamber 104, some air will enter the cavity 106 through the air groove 107. When the air enters the cavity 106, the hollow rubber block 105 can expand. The expanded rubber block 105 can squeeze the inner wall of the gap in the sole, thereby increasing the friction and reducing the risk of the staff's sole slipping when climbing.

[0047] Instructions for use: When using the device, first place the device from the boat to the outside of the hull. Then, under the action of the magnet 205, the suction cup 203 can be attached to the outer wall of the hull. When climbing, the staff can climb up by stepping on the pedal 102. When the staff steps on the pedal 102, the piston cylinder 202 can be moved by the support rod 301, which not only cooperates with the vent pipe 502 to reduce the pressure in the suction cup 203, but also increases the distance between the outer wall of the hull and the fixed plate 101, so that the device remains in an inclined state for easy climbing. After the suction cup 203 is adsorbed on the hull, the fixed plate 101 can be fixed by the piston cylinder 202 and the piston rod 201, reducing the shaking of the chain rope 1 during climbing, making the climbing process easier and safer for the staff;

[0048] During the climbing process, the squeezing block 402 can also be used to squeeze the concave part on the side of the staff's shoe, reducing the risk of the staff's sole slipping during the climbing process, making the staff safer during the climbing process. At the same time, the expandable rubber block 105 can increase the friction between the staff's sole and the gap, making the friction greater, further reducing the risk of the staff's sole slipping when climbing.

[0049] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
