Description

A ladder Technical Field

[0001] This application relates to the field of ship outfitting technology, and specifically to a ladder. Background Technology

[0002] Currently, the inclined ladders used on ships are generally too steep due to the objective limitations of the ship's space layout, posing serious safety hazards. When people ascend these ladders, their forefoot can only touch the edge of the step, and when descending, their forefoot is always in the air, making them extremely prone to slipping and falling. Minor injuries may result in scrapes and sprains, while serious injuries can lead to fractures or even fatal falls from heights, posing a significant threat to the personal safety of ship workers.

[0003] Meanwhile, traditional ship ladders are fixed structures with no adjustable steps and no effective anti-slip surface. In the harsh environment of high humidity and salt spray at sea, the steps easily accumulate dust and become slippery, further exacerbating the instability of personnel walking on them. The handrails are simply fixed railings, only meeting basic support needs and failing to provide effective protection in case of a fall. Furthermore, the ladder lacks any monitoring or emergency response mechanisms, leaving it without timely safety measures in the face of severe ship rocking caused by strong winds and waves or sudden physical discomfort among personnel.

[0004] In addition, traditional inclined ladders only have a single function of passage and are not designed for energy utilization in combination with the lighting conditions of the ship's open areas, resulting in a waste of solar energy resources; cleaning of the ladders relies entirely on manual operation, which increases the ship's maintenance labor costs, and the fixed structural design cannot adapt to the complex usage scenarios in the land construction field. Overall, the practicality, functionality and safety of the ladders are difficult to meet the usage needs of modern ships and construction fields. Summary of the Invention

[0092] To address the safety hazards and waste of human and natural resources in the existing technology described above, this embodiment provides a ladder. The ladder of this embodiment includes a main body unit 100 and a monitoring unit 200;

[0093] Referring to Figure 1, the main unit 100 includes a pedal unit 11, a frame unit 12, and a handrail unit 13. The frame unit 12 connects to and supports the pedal unit 11 and the handrail unit 13.

[0094] The monitoring unit 200 includes a monitoring unit 21 and a control unit 22. The monitoring unit 21 acquires real-time status information of the main unit 100 and the staff and transmits it to the control unit 22. The control unit 22 is connected to the main unit 100 and controls the main unit 100 according to the real-time status information of the main unit 100 and the staff acquired by the monitoring unit 21.

[0095] Referring to Figures 2-8, the pedal unit 11 includes a first pedal module 111, a second pedal module 112, a moving module 113, and a support module 114. The first pedal module 111 has an upper surface and a lower surface that are disposed opposite to each other, and defines a first direction parallel to the upper surface of the first pedal module 111, a second direction parallel to the upper surface of the first pedal module 111 and perpendicular to the first direction, and a third direction perpendicular to the first and second directions. The second pedal module 112 is located on the side where the lower surface of the first pedal module 111 is located. The moving module 113 is connected to the first pedal module 111 and the second pedal module 112, and the second pedal module 112 can be moved by the moving module 113 to the side of the first pedal module 111 along the first direction and flush with the upper surface of the first pedal module 111. The support module 114 is connected to the first pedal module 111 and is used to support the first pedal module 111 and the moved second pedal module 112.

[0096] In practical applications, the monitoring unit 200 can automatically control the movement of the second pedal module 112 in the pedal unit 11 based on the status information of the pedal unit and the staff. When the monitoring unit 21 detects that a staff member is walking on the ladder, the control unit 22 controls the second pedal module 112 to move to the side of the first pedal module 111 along the first direction, thereby greatly increasing the projected area of ​​the pedal unit 11 along the third direction. This effectively solves the technical problem that traditional inclined ladders are subject to the objective limitations of the ship's space layout, resulting in a large overall tilt angle and a small contact area between the pedal unit 11 and the staff member's feet, which poses a serious safety hazard. This ensures the safety of the staff's passage.

[0097] In this embodiment, referring to Figures 3 and 4, the moving module 113 includes a first pedal guide rail 1131, a second pedal guide rail 1132, a third pedal guide rail 1133, a pedal slider 1134, a moving motor 1135, and a steering groove 1136. The first pedal guide rail 1131 extends along the second direction, is located on one side of the first pedal module 111 along the first direction, and is flush with the upper surface of the first pedal module 111; the second pedal guide rail 1132 extends along the third direction, is located on one side of the first pedal module 111 along the first direction, and is connected to the first pedal guide rail 1131; a steering groove 1136 is connected to the side of the second pedal guide rail 1132 along the third direction away from the first pedal guide rail 1131; the third pedal guide rail 1133 extends along the first direction, is located on one side of the second pedal module 112 along the second direction, and is connected to the steering groove 1136; the pedal slider 1134 is connected to the second pedal module 112 and is slidably connected to the third pedal guide rail 1133; the moving motor 1135 is connected to the pedal slider 1134 to drive the pedal slider 1134 to move the second pedal module 112.

[0098] In operation, the moving motor 1135 drives the pedal slider 1134 to move the second pedal module 112 along the third pedal guide rail 1133 towards the side closer to the turning groove 1136. At the turning groove 1136, the moving motor 1135 stops driving along the third pedal guide rail 1133 and instead drives the pedal slider 1134 to move the second pedal module 112 along the second pedal guide rail 1132 towards the side closer to the first pedal guide rail 1131, ultimately making the upper surface of the second pedal module 112 flush with the upper surface of the first pedal module 111. The coordinated design of the first pedal module 111, the second pedal module 112, and the moving module 113 significantly increases the contact area between the pedal unit 11 and the worker's foot, reducing the risk of the worker falling due to instability.

[0099] In this embodiment, the steering groove 1136 is used to realize directional communication between the third pedal guide rail 1133 and the second pedal guide rail 1132. It can be an independent communication structure connected to the second pedal guide rail 1132 and the third pedal guide rail 1133, or it can be directly provided with mutually cooperating notches on the second pedal guide rail 1132 and the third pedal guide rail 1133 to realize the directional change of the pedal slider 1134 between the second pedal guide rail 1132 and the third pedal guide rail 1133. Specifically, the design of the steering groove 1136 can be set according to actual needs, and no specific limitation is made here.

[0100] In this embodiment, the movable motor 1135 drives the pedal slider 1134 to move linearly along the third pedal guide rail 1133 and the second pedal guide rail 1132. The type and number of movable motors 1135 can be designed according to actual conditions and are not specifically limited here. In this embodiment, the movable motor 1135 can be precisely controlled by programming or other suitable methods to achieve precise displacement of the second pedal module 112. Specifically, the method of precisely controlling the movable motor 1135 can be selected according to actual needs and is not specifically limited here. The third pedal guide rail 1133 and the second pedal guide rail 1132 are used to restrict and support the movement direction of the pedal slider 1134. The type and number of the third pedal guide rail 1133 and the second pedal guide rail 1132 can also be selected according to the actual situation. Preferably, there are two second pedal guide rails 1132. The second pedal guide rail 1132 is a dihedral angle steel. One right-angled surface of the second pedal guide rail 1132 is attached to one side of the first pedal module 111 along the first direction, and the other right-angled surface is perpendicular to one side of the first pedal module 111 along the first direction. The right-angled openings of the two second pedal guide rails 1132 are arranged opposite each other. Both second pedal guide rails 1132 extend along the third direction and are respectively connected to the two sides of the first pedal guide rail 1131 arranged opposite each other along the second direction. A steering groove 1136 is connected to the side of the second pedal module 112 away from the first pedal guide rail 1131 along a third direction. There are two third pedal guide rails 1133, both of which extend along a first direction and are located on opposite sides of the second pedal module 112 along a second direction. They are fixedly connected to the two steering grooves 1136 respectively. The third pedal guide rails 1133 are trihedral angle steels, and the opening surfaces of the two third pedal guide rails 1133 are arranged opposite to each other. In this embodiment, the first pedal guide rail 1131, the second pedal guide rail 1132 and the third pedal guide rail 1133 can be connected by welding, screw fixing or other suitable methods. Preferably, the first pedal guide rail 1131, the second pedal guide rail 1132 and the third pedal guide rail 1133 are fixed by welding.

[0101] In this embodiment, referring to Figures 5 and 6, the support module 114 includes a support beam 1141, a support space 1142, a support guide rail 1143, a support slider 1144, and a support motor 1145.

[0102] In this embodiment, the support beam 1141 can be connected to the first pedal module 111, the second pedal guide rail 1132 and the third pedal guide rail 1133 by screws, welding or other suitable means. Preferably, the support beam 1141 is fixed to the first pedal module 111, the second pedal guide rail 1132 and the third pedal guide rail 1133 by welding.

[0103] After the second pedal module 112 moves to the side of the first pedal module 111 along the first direction, the support motor 1145 drives the support slider 1144 to move along the support guide rail 1143 towards the side closer to the second pedal module 112, so as to provide support for the second pedal module 112 along the third direction. The number of support guide rails 1143 can be designed according to actual needs to achieve stable support for the second pedal module 112 along the third direction.

[0104] In this embodiment, referring to Figures 7 and 8, the first pedal module 111 includes a first outer shell 1111, a first cavity 1112, a first moving part 1113, a second moving part 1114, a first driving part 1115, and a second driving part 1116. The first outer shell 1111 has a first front side and a first back side disposed opposite to each other along a third direction, and the first front side and the first back side are provided with a plurality of first openings 101; the first outer shell 1111 has an internal hollow structure to form the first cavity 1112, and the first moving part 1113, the second moving part 1114, the first driving part 1115, and the second driving part 1116 are disposed in the first cavity 1112. The first driving part 1115 drives the first moving part 1113 to move along a third direction, and the second driving part 1116 drives the second moving part 1114 to move along a third direction.

[0105] The first movable part 1113 includes a first movable plate 102 and a plurality of first protrusions 103. The first movable plate 102 is parallel to the first front side, and the plurality of first protrusions 103 are disposed on the side of the first movable plate 102 near the first front side, and the first protrusions 103 correspond one-to-one with the first openings 101 on the first front side. The second movable part 1114 includes a second movable plate 104 and a plurality of second protrusions 105. The second movable plate 104 is parallel to the first back side, and the plurality of second protrusions 105 are disposed on the side of the second movable plate 104 near the first back side, and the second protrusions 105 correspond one-to-one with the first openings 101 on the first back side.

[0106] The first drive unit 1115 includes a first telescopic motor 106 and a first telescopic rod 107.

The second drive unit 1116 includes a second telescopic motor 108 and a second telescopic rod 109. The two ends of the second telescopic rod 109 are respectively connected to the second telescopic motor 108 and the second moving plate 104 to realize the movement of the second moving plate 104 in a third direction.

[0107] In the non-working state, the first moving part 1113 and the second moving part 1114 are hidden inside the first pedal module 111, and the first boss 103 is flush with the first front side of the first housing 1111 along a third direction away from the first moving plate 102, and the second boss 105 is flush with the first back side of the first housing 1111 along a third direction away from the second moving plate 104. In the working state, the first moving part 1113 and the second moving part 1114 move along a third direction under the drive of the first drive part 1115 and the second drive part 1116, so that the first boss 103 extends out of the first opening 101 on the first front side under the drive of the first drive part 1115, and the second boss 105 extends out of the first opening 101 on the first back side under the drive of the second drive part 1116, so that the upper and lower surfaces of the first pedal module 111 are in a "keyboard shape". This design is to increase the friction of the foot of the worker stepping on the first pedal module, so as to increase the anti-slip coefficient of the ladder.

[0108] In this embodiment, the first protrusion 103 and the second protrusion 105 are used to increase the surface friction of the first pedal module 111. The projected shape of the first protrusion 103 and the second protrusion 105 along the third direction can be circular, square, or other suitable shapes. The size and number of the first protrusion 103 and the second protrusion 105 can be set according to actual needs and are not specifically limited here. When the first opening 101 is provided on the first back side of the first housing 1111, care should be taken to avoid the support beam 1141 and the support guide rail 1143. The shape, size, and number of the first opening 101 match the projected shape, size, and number of the first protrusion 103 and the second protrusion 105 along the third direction so that there are no gaps between the edges of all the first protrusions 103 and the second protrusion 105 and the first opening 101, thereby preventing debris from falling into the first cavity 1112.

[0109] In this embodiment, the principle is the same as in Figures 7 and 8. The second pedal module 112 includes a second outer shell 1121, a second cavity 1122, a third moving part 1123, a fourth moving part 1124, a third driving part 1125, and a fourth driving part 1126. The second outer shell 1121 has a second front and a second back disposed opposite to each other along a third direction, and the second front and the second back are provided with a plurality of second openings 201. The second outer shell has an internal hollow structure to form the second cavity 1122. The third moving part 1123, the fourth moving part 1124, the third driving part 1125, and the fourth driving part 1126 are disposed in the second cavity 1122. The third driving part 1125 drives the third moving part 1123 to move along a third direction, and the fourth driving part 1126 drives the fourth moving part 1124 to move along a third direction.

[0110] The third moving part 1123 includes a third moving plate 202 and a plurality of third protrusions 203. The third moving plate 202 is parallel to the second front side, and the plurality of third protrusions 203 are disposed on the side of the third moving plate 202 near the second front side, and the third protrusions 203 correspond one-to-one with the second openings 201 on the second front side; the fourth moving part 1124 includes a fourth moving plate 204 and a plurality of fourth protrusions 205. The fourth moving plate 204 is parallel to the second back side, and the plurality of fourth protrusions 205 are disposed on the side of the fourth moving plate 204 near the second back side, and the fourth protrusions 205 correspond one-to-one with the second openings 201 on the second back side;

[0111] The third drive unit 1125 includes a third telescopic motor 206 and a third telescopic rod 207. The two ends of the third telescopic rod 207 are respectively connected to the third telescopic motor 206 and the third moving plate 202 to realize the movement of the third moving plate 202 in a third direction. The fourth drive unit 1126 includes a fourth telescopic motor 208 and a fourth telescopic rod 209. The two ends of the fourth telescopic rod 209 are respectively connected to the fourth telescopic motor 208 and the fourth moving plate 204 to realize the movement of the fourth moving plate 204 in a third direction.

[0112] In the non-working state, the third moving part 1123 and the fourth moving part 1124 are hidden inside the second pedal module 112, and the third boss 203 is flush with the second front side of the second housing 1121 along the third direction away from the third moving plate 202, and the fourth boss 205 is flush with the second back side of the second housing 1121 along the third direction away from the fourth moving plate 204. In the working state, the third moving part 1123 and the fourth moving part 1124 move along the third direction under the drive of the third drive part 1125 and the fourth drive part 1126, so that the third boss 203 extends out of the second opening 201 on the second front side under the drive of the third drive part 1125, and the fourth boss 205 extends out of the second opening 201 on the second back side under the drive of the fourth drive part 1126, so that the upper and lower surfaces of the second pedal module 112 present a "keyboard shape". This design is to increase the friction of the foot of the worker stepping on the second pedal module, so as to increase the anti-slip coefficient of the ladder.

[0113] In this embodiment, the third protrusion 203 and the fourth protrusion 205 are used to increase the surface friction of the second pedal module 112. The projected shape of the third protrusion 203 and the fourth protrusion 205 along the third direction can be circular, square, or other suitable shapes. The size and number of the third protrusion 203 and the fourth protrusion 205 can be set according to actual needs and are not specifically limited here. The shape, size, and number of the second opening 201 match the projected shape, size, and number of the third protrusion 203 and the fourth protrusion 205 along the third direction, so that there are no gaps between the edges of all the third protrusions 203 and the fourth protrusion 205 and the second opening 201, thereby preventing debris from falling into the second cavity 1122.

[0114] After the staff has finished using the ladder of the present invention, the first telescopic motor 106, the second telescopic motor 108, the third telescopic motor 206, the fourth telescopic motor 208 and the moving motor 1135 run in reverse, so that the step unit 11 of the ladder of the present invention returns to its original state.

[0116] One of the differences between the ladder in this application and a regular inclined ladder is that the side of the tread unit 11 away from the moving module 113 along the first direction of a regular inclined ladder is completely empty and has no fixed connection design. All tread units 11 from top to bottom are connected to the connecting frames 121 erected on opposite sides along the second direction. However, the frame unit 12 of this invention is designed with a connecting strip 122 at the height of each tread unit 11. The tread unit 11 is fixedly connected to the connecting strip 122, and there are as many connecting strips 122 as there are tread units 11.

[0117] In this embodiment, the handrail unit 13 includes a first column 131, a second column 132, a first connecting unit 133, and a second connecting unit 134. Both the first column 131 and the second column 132 extend in a third direction and are respectively connected to connecting frames 121 provided on both sides of the pedal unit 11; the first connecting unit 133 is connected to the end of the first column 131 away from the connecting frame 121; and the second connecting unit 134 is connected to the end of the second column away from the connecting frame 121.

[0118] In this embodiment, the first column 131 and the second column 132 are arranged opposite to each other along a second direction. The first column 131 includes a life-saving net 1311, a third opening 1312, and a first control unit 1313. Referring to FIG9, the life-saving net 1311 is arranged in a roll shape within the first column 131 with the third direction as its axial direction; the third opening 1312 extends along the third direction and is located on the side of the first column 131 near the second column 132 along the second direction, so that the life-saving net 1311 can pass through; the first control unit 1313 is disposed within the first column 131. On the one hand, the first control unit 1313 is used to fix the life-saving net 1311; on the other hand, the first control unit 1313 drives the life-saving net 1311 to pass through the third opening 1312 and move along the second direction into the second column 132.

[0119] In this embodiment, the second column 132 includes a fourth opening 1321 and a second control unit 1322. The fourth opening 1321 extends in a third direction and is disposed on the side of the second column 132 close to the first column 131 in a second direction, so that the life net 1311 can pass through. The second control unit 1322 is disposed inside the second column 132. On the one hand, the second control unit 1322 is used to fix the life net 1311. On the other hand, the second control unit 1322 drives the life net 1311 to pass through the fourth opening 1321 and move back into the first column 131 in the second direction.

[0120] In this embodiment, referring to Figures 10 and 12, the first control unit 1313 includes a second rotary motor 301, a first control guide rail 302, a second control guide rail 303, a first control slider 304, a second control slider 305, a first control motor 306, a second control motor 307, a third control motor 308, a first spring 309, a second spring 3010, a catapult hammer 3011, and a catapult plate 3012.

[0121] In this embodiment, the second rotary motor 301 extends along a third direction, and its two ends are respectively connected to the two sides of the first column 131 that are arranged opposite to each other along the third direction. In addition to the second rotary motor 301, the first control unit 1313 has two of each of the following components: first control rail 302, second control rail 303, first control slider 304, second control slider 305, first control motor 306, second control motor 307, third control motor 308, first spring 309, second spring 3010, catapult hammer 3011, and catapult plate 3012, which are symmetrically arranged on the two sides of the first column 131 that are arranged opposite to each other along the third direction.

[0122] Taking the side of the first column 131 near the first connecting unit 133 along a third direction as an example, the first control guide rail 302 extends along a second direction and is located on the side of the second rotary motor 301 near the third opening 1312 along the second direction, and is connected to the side of the first column 131 near the first connecting unit 133 along a third direction; the first control motor 306 is located on the side of the first control guide rail 302 away from the second rotary motor 301 along the second direction; the first spring 309 is located on the side of the first control motor 306 away from the first control guide rail 302 along a third direction; the first control slider 304 is connected to the side of the first control motor 306 and the first spring 309 near the second rotary motor 301 along the second direction, and is slidably connected to the first control guide rail 302; the first control slider 304 is provided with a first through hole;

[0123] In this embodiment, the first control slider 304 is L-shaped, including a first right-angled side and a second right-angled side. The first right-angled side extends along a third direction toward the first control guide rail 302, and the second right-angled side extends along a second direction toward the second rotary motor 301. A first through hole is provided on the second right-angled side. The catapult hammer 3011 is disposed on the side of the first control slider 304 away from the first control guide rail 302 along a third direction. A second through hole is provided on the catapult hammer 3011. The second through hole and the first through hole on the first control slider 304 are coaxially arranged along a third direction.

[0124] The ejection plate 3012 is located on the side of the ejection hammer 3011 away from the second rotary motor 301 along the second direction, and the ejection plate 3012 is connected to the life-saving net 1311. In this embodiment, the life-saving net 1311 is wound into a roll around the second rotary motor 301 as an axis. A dart triangular prism 3013 is fixedly connected to the edge of the life-saving net 1311 that is parallel to the third direction and exposed to the outside of the second rotary motor 301. The ejection plate 3012 is fixedly connected to the dart triangular prism 3013 on the life-saving net 1311. The structural design of the dart triangular prism 3013 can improve the speed and accuracy of the life-saving net 1311 ejected from the third opening 1312 into the fourth opening 1321.

[0125] In this embodiment, the second spring 3010 is L-shaped, including a third right-angled side and a fourth right-angled side. The third right-angled side extends along a third direction away from the first control guide rail 302, and the fourth right-angled side extends along a second direction towards the second rotary motor 301. The third right-angled side passes sequentially through the first through hole on the first control slider 304 and the second through hole on the catapult hammer 3011. The third control motor 308 is fixedly connected to the side of the second spring 3010 along the third direction towards the first control guide rail 302 and is slidably connected to the first control guide rail 302. The second control guide rail 303... Extending along the second direction and parallel to the first control rail 302, in this embodiment, there are two second control rails 303, respectively disposed on both sides of the first control rail 302 that are opposite to each other along the first direction; the second control motor 307 is disposed inside the second control rail 303; the second control slider 305 is connected to the second control motor 307 and slidably connected to the second control rail 303, so that the second control motor 307 drives the second control slider 305 to move along the second control rail 303, and the second control slider 305 is connected to the third right-angle side and the fourth right-angle side of the second spring 3010.

[0126] In practical applications, referring to Figures 13 and 17, when the monitoring system 21 detects that a worker has fallen due to dizziness or other physical reasons, or due to violent rocking of the ship caused by strong winds and waves, the first control motor 306 drives the first control slider 304 to move along the first control guide rail 302 towards the second rotary motor 301. The third control motor 308 drives the second spring 3010 to move along the first control guide rail 302 towards the second rotary motor 301. The second control motor 307 drives the second control slider 305 to move along the second control guide rail 303 towards the second rotary motor 301. The first control motor 306, the second control motor 307, and the third control motor 308 move at the same speed. When the third control motor 308 moves to the side of the first control guide rail 302 that is closer to the second rotary motor 301 in the first direction, the first spring... Spring 309 and the second spring 3010 are in a stretched state, and the ejector hammer 3011 is away from the ejector plate 3012. At this time, the first control motor 306, the second control motor 307 and the third control motor 308 move rapidly in opposite directions. With the rebound force of the first spring 309 and the second spring 3010, the ejector hammer 3011 is suddenly ejected to the ejector plate 3012. At the same time, the second rotary motor 301 rotates and releases the life net 1311. Under the ejection force of the ejector hammer 3011, the dart triangular post 3013 and the ejector plate 3012 carrying the life net 1311 are ejected from the third opening 1312 like an "arrow released from a bow" and into the fourth opening 1321. This prevents the staff from falling and catches them, avoiding the safety hazards of minor scrapes or sprains, or even serious fractures or death.

[0127] In this embodiment, referring to Figures 11 and 14, the second control unit 1322 includes a third rotary motor 401, a fourth rotary motor 402, a third control guide rail 403, a fourth control motor 404, and a third control slider 405.

[0128] Both the third rotary motor 401 and the fourth rotary motor 402 extend along the third direction, and both ends are respectively connected to the two sides of the second column 132 that are arranged opposite to each other along the third direction. The rotation directions of the third rotary motor 401 and the fourth rotary motor 402 are opposite.

[0129] In this embodiment, there are two of each of the third control guide rail 403, the fourth control motor 404, and the third control slider 405, which are symmetrically arranged on both sides of the second column 132 along the third direction. Taking the side of the second column 132 near the second connecting unit 134 along the third direction as an example, the third control guide rail 403 extends along the third direction and is located on the side of the second column 132 near the first column 131 along the second direction, and is located on the side of the fourth opening 1321 near the second connecting unit 134 along the third direction.

[0130] The third control slider 405 is L-shaped, including a fifth right-angled side and a sixth right-angled side. The fifth right-angled side extends along the second direction toward the direction close to the first column 131, and the sixth right-angled side extends along the third direction toward the direction close to the fourth opening 1321. The side of the fifth right-angled side that is close to the first column 131 along the second direction is slidably connected to the third control guide rail 403.

[0131] The fourth control motor 404 is disposed inside the third control guide rail 403 and connected to the third control slider 405 to drive the third control slider 405 to move along the third control guide rail 403.

[0132] In practical applications, referring to Figure 15, after the life-saving net 1311 is ejected into the fourth opening 1321, the fourth control motor 404 drives the third control slider 405 to move along the third control guide rail 403 towards the side closer to the fourth opening 1321. The sixth right-angled side of the third control slider 405 abuts against the ejection plate 3012 to prevent the life-saving net 1311 from rebounding from the fourth opening 1321. At the same time, the third rotation motor 401 and the fourth rotation motor 402, which rotate in opposite directions, rotate to fix the life-saving net 1311 inside the second column 132.

[0133] In this embodiment, the main body unit 100 is made of stainless steel, titanium alloy, aluminum alloy or other suitable corrosion-resistant materials. Preferably, the main body unit 100 is made of stainless steel to adapt to environmental conditions such as water vapor and salt spray on the sea surface.

[0134] The monitoring unit 21 can employ sensors or other devices capable of monitoring the real-time status information of the ladder body and the workers. In this embodiment, the monitoring unit 21 includes a gravity sensor 211, a vision sensor 212, a light sensor 213, and a timing sensor 214. The gravity sensor 211 and the timing sensor 214 are integrated on the side of the current deck and the lower deck near the ladder. The gravity sensor 211 is used to sense and acquire the weight information of the workers, and the timing sensor 214 is used to sense and acquire the walking time data of the workers and transmit it to the control unit 22 to calculate the walking speed of the workers. In addition, gravity sensor 211 and timing sensor 214 are also integrated on the pedal unit 11 to obtain real-time status information such as the worker's ascent, descent, walking position, and walking speed. This real-time status information of the worker is transmitted to the control unit 22. The control unit 22 controls the pedal unit 11 to cooperate with the worker's activities. Taking the worker descending the ladder as an example, when the monitoring unit 21 detects that the worker walks to the area of ​​the deck near the ladder, the control unit 22 controls the first pedal unit 11 to unfold. That is, the second pedal module 112 moves to the side of the first pedal module 111 along the first direction through the moving module 113. When the monitoring unit 21 detects that the worker walks to the first pedal unit 11, the control unit 22 controls the second pedal unit 11 to unfold. When the worker's center of gravity falls on the second pedal unit 11, the control unit 22 controls the first pedal unit 11 to retract and controls the unfolding of the third pedal unit 11, and so on.

[0135] Therefore, regardless of which step unit 11 the worker steps on, the control unit 22 can coordinate and control the unfolding or retraction of that step unit 11 and the step units 11 above and below it. The unfolding of the lower step unit 11 and the retraction of the upper step unit 11 are continuous and coordinated with the worker's steps until the worker walks to the lower deck, at which point all the step units 11 on the ladder return to their original state.

[0136] The visual sensor 212 is used to acquire real-time video information of workers walking on the ladder. Its installation location is not specifically limited here. The control unit 22 acquires the dynamic information of the workers from the visual sensor 212. When a worker falls, the control unit 22 controls the life-saving net 1311 in the handrail unit 13 to be ejected, thus protecting the worker. Due to the strong sunlight on the sea surface, the light sensor 213 is used to acquire sunlight signals and transmit them to the control unit 22. The control unit 22 controls the rotation module 123 in the frame unit 12 to make the two sides of the pedal unit 11, which are positioned opposite each other in a third direction, perpendicular to the direction of sunlight, thereby acquiring more solar energy and improving the utilization rate of solar energy.

[0137] In this embodiment, referring to FIG21, the control unit 22 includes a control touch screen 221, a first status signal line 222, a second status signal line 223, a first control signal line 224, a second control signal line 225, and a control button 226. The control touch screen 221 has a computer chip and can be installed on the outside of the connecting frame 121 or on the bulkhead near the ladder of the present invention. The control touch screen 221 displays the operation status and operating conditions of the present invention in real time, and realizes local intelligent fully automatic control of the ladder of the present invention. The control unit 22 receives status signals from the pedal unit 11, frame unit 12, handrail unit 13, cleaning unit 14, power generation unit 15, and lighting unit 16, as well as monitoring signals from the monitoring unit 21, through the first status signal line 222, and sends control signals to the pedal unit 11, frame unit 12, handrail unit 13, cleaning unit 14, power generation unit 15, and lighting unit 16 through the first control signal line 224. The control unit 22 transmits its real-time operating status to a remote device via the second status signal line 223, and is simultaneously controlled by the remote device via the second control signal line 225. A control button 226 is located on the handrail unit 13. When a worker who has fallen stands up and regains their footing on the footrest unit, they can press the nearest control button 226 to reverse the operation of the first control unit 1313 and the second control unit 1322, retracting the safety net 1311 in the second pillar 132 back into the first pillar 131, allowing the worker to continue walking. The control touchscreen 221 is connected to the first status signal line 222, the second status signal line 223, the first control signal line 224, the second control signal line 225, and the control button 226 for manual control by the worker or automated control according to the present invention.

[0138] In an optional embodiment, the main unit 100 further includes a cleaning unit 14, which is connected to the pedal unit 11 and the monitoring unit 200. The monitoring unit 200 monitors and controls the cleaning unit 14 to clean the pedal unit 11.

[0139] In this embodiment, referring to FIG16, the cleaning unit 14 includes a cleaning guide rail 141, a cleaning motor 142, a fifth telescopic motor 143, a cleaning scraper 144, and a heating wire 145. The cleaning guide rail 141 is disposed on the side of the first pedal module 111 away from the moving module 113 along the first direction, and the upper surface of the cleaning guide rail 141 is flush with the upper surface of the first pedal module 111; the cleaning motor 142 is disposed inside the cleaning guide rail 141 and is slidably connected to the cleaning guide rail 141; the fifth telescopic motor 143 is connected to the side of the cleaning motor 142 away from the cleaning guide rail 141 along the first direction; the cleaning scraper 144 is connected to the side of the fifth telescopic motor 143 away from the cleaning motor 142 along the first direction; the heating wire 145 is disposed inside the first cavity 1112 of the first pedal module 111 and inside the second cavity 1122 of the second pedal module 112.

[0140] In this embodiment, the cleaning scraper 144 adopts a telescopic design. When the second pedal module 112 moves to the side of the first pedal module 111 along the first direction, the cleaning scraper 144 extends and unfolds along the first direction to achieve a synchronous cleaning effect on the upper surfaces of the first pedal module 111 and the second pedal module 112.

[0141] In practical applications, when the second pedal module 112 moves to the side of the first pedal module 111 along the first direction, the cleaning motor 142 drives the fifth telescopic motor 143 to move along the cleaning guide rail 141. The fifth telescopic motor 143 drives the telescopic cleaning scraper 144 to extend away from the cleaning guide rail 141 along the first direction, and moves along the second direction on the upper surfaces of the first pedal module 111 and the second pedal module 112. In this application, the contact point between the telescopic cleaning scraper 144 and the first pedal module 111 and the second pedal module 112 is designed to be rubber, so as to achieve a good cleaning effect on the upper surfaces of the first pedal module 111 and the second pedal module 112. If it rains, the residual moisture on the upper surfaces of the first pedal module 111 and the second pedal module 112 can be quickly dried by the heating effect of the heating wire 145, so as to achieve an anti-slip effect.

[0142] It should be noted that the cleaning unit 14 cleans the step unit 11 when no personnel are walking on the ladder. Personnel can pre-set the time interval for each self-cleaning on the control touch screen 221 according to regular needs, such as 2 hours, 3 hours, 6 hours or other suitable time intervals. Personnel can also directly control the operation of the cleaning unit 14 on the control touch screen 221 according to the actual needs of a certain period of time. In addition, ship monitoring personnel can also remotely control the operation of the cleaning unit 14 on the ship monitoring center console through the second control signal line 225.

[0144] In this embodiment, the frame unit 12 further includes a rotation module 123, which includes a rotation motor bracket 1231 and a first rotation motor 1232. The rotation motor bracket 1231 is connected to the connecting strip 122; the rotation motor 1232 connects the rotation motor bracket 1231 and the pedal unit 11, and is used to drive the pedal unit 11 to rotate at different angles according to different needs, such as rotating upwards to try to catch the worker when he falls, or rotating with the angle of the sunlight to receive more sunlight.

[0145] In practical applications, referring to Figure 17, when the monitoring unit 21 detects that a worker has fallen, it transmits the signal to the control unit 22. The control unit 22 controls the first rotary motor 1232 connected to the pedal unit 11 closest to the worker's feet, causing the pedal unit 11 to rotate clockwise at an appropriate angle to catch the fallen worker and allow him to stand firmly on the pedal unit 11. At the same time, the life-saving net 1311 in the first column 131 closest to the worker's feet immediately ejects and gets into the second column 132 of the corresponding height to catch the worker falling from above, preventing him from falling further.

[0146] In this embodiment, referring to Figures 18-20, the monitoring unit 21 monitors the angle signal of sunlight and transmits it to the control unit 22. The control unit 22 controls the first rotary motor 1232 in the rotary module 123 to rotate and controls the first boss 103, the second boss 105, the third boss 203 and the fourth boss 205 to extend outward so that the power generation device 151 provided on the first pedal module 111 and the second pedal module 112 can receive more sunlight, thereby improving the power generation efficiency of the power generation device 151.
