[0002] With the rapid development of the shipping industry, ships are docking and leaving ports more and more frequently. Pilots usually have to use a pilot ladder to get on and off ships at sea. Currently, the pilot ladder used on ships uses ropes to connect the pedals.

[0003] For example, the Chinese patent authorization announcement number is CN215752910U, "A new type of pilot ladder, involving the technical field of ladders, comprising a box, a rotating shaft is rotatably connected inside the box, a motor is fixedly installed on the side of the box, one end of the ladder is fixedly connected to the outer wall of the rotating shaft, and a connecting plate is provided at the bottom of the front of the box; a connecting sleeve is fixedly provided on one side of the ladder, a connecting hole is provided inside the connecting sleeve, and a connecting rod is inserted into the connecting hole"; In the above-mentioned comparative document, the soft ladder is fixed by connecting the connecting rod with the connecting hole in the connecting sleeve, which reduces the problem of the rope shaking when climbing and stepping on the pedal, and avoids a certain degree of danger; through the cooperation of the support plate and the connecting rod, the box has a certain installation space. During installation, the box is first fixed to one place, and the rotation of the motor drives the rotation of the rotating shaft to release the soft ladder from the opening, and then the connecting sleeve of the hanging part is connected through the connecting rod, and the threaded hole at the top of the connecting rod is connected to the threaded rod, which is convenient and quick.

[0004] However, when the pilot ladder on the above-mentioned ship is in use, the ladder collides with the anti-wear material on the deck when being retracted and extended on the deck, and the anti-wear material is subjected to friction and compression, resulting in deformation and damage at the connection between the anti-wear material and the deck. When the ladder is being retracted and guided, the gap between the ladder and the outer plate gradually increases. When the crew climbs up the ladder, the ladder is affected by wind force and other factors, and the ladder shakes greatly, resulting in a great safety hazard when the crew climbs up. Summary of the invention

[0005] The object of the present invention is to provide a pilot ladder retracting and lowering structure, which can provide stable guidance for the retracting and lowering of the ladder, and can position the ladder between the ladder and the hull outer plate, so as to position the ladder when the crew climbs up the ladder.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a retractable and retractable structure for a pilot ladder, comprising a deck, a handrail, a box, a winch, an outer plate, and a ladder, wherein a first positioning seat is integrally formed at the bottom of the box, an anti-wear material is provided on one side of the top of the deck, a connecting seat is fixedly installed on the top of the deck close to the ladder, connecting blocks and connecting blocks are integrally formed at both ends and the middle of the connecting seat, a lifting cylinder is fixedly installed on the side of the outer plate away from the ladder, a connecting frame is fixedly connected to the telescopic end of the lifting cylinder, and an abutment clamp is fixedly connected to the end of the connecting frame away from the lifting cylinder, the ladder comprises symmetrically arranged connecting rods, two groups of connecting rods are respectively hinged at both ends with a first side rod and a second side rod, and positioning locking rods are provided at adjacent ends of the first side rod and the second side rod.

[0007] Preferably, the bottom of the connecting seat is a T-shaped structure, the second positioning seat is an L-shaped structure, and one side of the first positioning seat and one side of the second positioning seat are fixedly connected to two sides of the bottom of the connecting seat by bolts respectively.

[0008] Preferably, the arcuate surface on one side of the wear-resistant material abuts against the top of the outer plate.

The soft ladder 8 includes symmetrically arranged connecting rods 81, and the two ends of the two groups of connecting rods 81 are respectively hinged with a first side rod 82 and a second side rod 83, and a positioning lock rod 84 is arranged at the adjacent end of the first side rod 82 and the second side rod 83; The hoist 4 in the box body 3 can retract and release the soft ladder 8 wound on the outside of the output end. The soft ladder 8 can be guided downward by the top arc surface of the anti-wear material 6 and extend to the outer plate 5. The crew can retract and release the soft ladder 8 and climb the soft ladder 8 to perform docking operations after sailing; The anti-wear material 6 is welded to the deck 1 through the bottom connecting seat 61, and the two sides of the bottom of the connecting seat 61 are positioned by bolts through the first positioning seat 31 and the second positioning seat 62 at the bottom of the box body 3, so that the connection stability between the two sides of the bottom of the connecting seat 61 and the ship deck 1 is increased, and the inner side of the arc-shaped anti-wear material 6 and the connecting seat 61 are reinforced by multiple groups of welded connecting blocks 63 and connecting blocks 64. In this way, when the soft ladder 8 is retracted, the anti-wear material 6 is subjected to long-term extrusion and can still fit closely with the installation position of the deck 1 to prevent deformation, so that the arc-shaped anti-wear material 6 can be stably installed at the placement position of the soft ladder 8, and can play a role in stabilizing and guiding the soft ladder 8; The first side rod 82 in the soft ladder 8 can slide in the guide groove 831 opened on the front side between the positioning lock rod 84 and the second side rod 83, and the positioning lock rod 84 can be rotated to make the positioning lock rod 84 correspondingly inserted into the corresponding positioning groove 832, so that the spacing between the two sides of the soft ladder 8 can be flexibly adjusted. When the soft ladder 8 is unwound and climbed, the length can be positioned and the overall unwinding length of the soft ladder 8 can be adjusted. The telescopic end of the jacking cylinder 7 drives the connecting frame 71 to be telescopic, so that the end of the connecting frame 71 can contact the clamp 72 to contact and position the side rods on both sides of the soft ladder 8 with the guard plate 51. In this way, when the crew on the soft ladder 8 climbs, it can ensure that the soft ladder 8 is positioned with the outer plate 5, which is more convenient for the crew to climb.

[0021] Among them, the bottom of the connecting seat 61 is a T-shaped structure, the second positioning seat 62 is an L-shaped structure, one side of the first positioning seat 31 and one side of the second positioning seat 62 are fixedly connected to the two sides of the bottom of the connecting seat 61 by bolts respectively, and the arc surface on one side of the anti-wear material 6 is in conflict with the top of the outer plate 5, and the connecting block 63 and the connecting block 64 are respectively integrally formed with the inner arc surface of the anti-wear material 6, and the inner side of the arc-shaped anti-wear material 6 and the connecting seat 61 are reinforced by multiple groups of welded connecting blocks 63 and connecting blocks 64. In this way, when the soft ladder 8 is retracted and released, the anti-wear material 6 is subjected to long-term extrusion, and can still fit tightly with the installation position of the deck 1 to prevent deformation, so that the arc-shaped anti-wear material 6 can be stably installed at the placement position of the soft ladder 8, which can play a role in stabilizing and guiding the soft ladder 8.

[0022] Among them, a guard plate 51 is symmetrically fixedly installed on one side of the outer plate 5, and the guard plate 51 is an L-shaped structure. Through grooves 52 are opened at equal intervals on one side of the outer plate 5 near the guard plate 51. The soft ladder 8 is fixedly connected to the output end of the winch 4, and the bottom of the soft ladder 8 extends between the outer plate 5 and the guard plate 51. The soft ladder 8 conflicts with the arc-shaped surface of the top of the wear-resistant material 6. The first side rod 82 in the soft ladder 8 can slide in the guide groove 831 opened on the front side between the positioning lock rod 84 and the second side rod 83, and the positioning lock rod 84 can be rotated so that the positioning lock rod 84 is correspondingly inserted into the corresponding positioning groove 832. In this way, the spacing between the two sides of the soft ladder 8 can be flexibly adjusted. When the soft ladder 8 is unrolled and climbed, the length can be positioned and the overall unwinding length of the soft ladder 8 can be adjusted.

[0023] Among them, a guide groove 831 is provided on the outer side of the second side rod 83, and positioning grooves 832 are symmetrically provided on both sides of the inner wall of the guide groove 831.

The telescopic end of the jacking cylinder 7 drives the connecting frame 71 to be telescopic, so that the end of the connecting frame 71 can contact the clamp 72 to position the side rods on both sides of the soft ladder 8 against the guard plate 51. In this way, when the crew on the soft ladder 8 climbs, it can ensure that the soft ladder 8 and the outer plate 5 are positioned, which is more convenient for the crew to climb.

When the soft ladder 8 is unwound and climbed, the length can be positioned and the overall unwinding length of the soft ladder 8 can be adjusted. The telescopic end of the jacking cylinder 7 drives the connecting frame 71 to extend and retract, so that the end of the connecting frame 71 can contact the clamp 72 to contact and position the side rods on both sides of the soft ladder 8 with the guard plate 51. In this way, when the crew on the soft ladder 8 climbs, it can ensure that the soft ladder 8 is positioned with the outer plate 5, which is more convenient for the crew to climb; The anti-wear material 6 is welded to the deck 1 through a bottom connecting seat 61, and the two sides of the bottom of the connecting seat 61 are positioned with bolts through the first positioning seat 31 and the second positioning seat 62 at the bottom of the box body 3, so that the connection stability between the two sides of the bottom of the connecting seat 61 and the ship deck 1 is increased, and the inner side of the arc-shaped anti-wear material 6 and the connecting seat 61 are reinforced by multiple groups of welded connecting blocks 63 and connecting blocks 64. In this way, when the soft ladder 8 is retracted or released, the anti-wear material 6 is subjected to long-term compression and can still fit tightly with the installation position of the deck 1 to prevent deformation, so that the arc-shaped anti-wear material 6 can be stably installed at the placement position of the soft ladder 8, which can play a role in stabilizing and guiding the soft ladder 8.
