[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The utility model is a convenient rope ladder retracting, fixing and platform device, which is mainly composed of a channel steel panel 1, an electromagnetic suction channel steel 3 and two electromagnetic suction platform panels 2. Figure 1-3 as its basic component.

[0025] See also Figure 1-6 A rope ladder retractable fixing and platform device includes a channel steel panel 1; a pair of long sides of the channel steel panel 1 are respectively hinged with an electromagnetic suction platform panel 2; one of a pair of short sides is vertically fixed with an ordinary channel steel, and the other is hingedly fixed with an electromagnetic suction channel steel 3; the length of the short side of the channel steel panel 1 is less than the width of the rope ladder step;

[0026] In this embodiment, the length of the long side of the channel steel panel 1 is 0.8-1.2 meters.

[0027] In this embodiment, the width of the electromagnetic suction groove steel 3 is 0.2-0.4 meters.

[0028] In this embodiment, an electromagnetic suction indicator light 4 is provided on the side of the electromagnetic suction groove steel 3.

[0029] In this embodiment, see Figure 6 The electromagnetic suction channel steel 3 is hinged to the channel steel panel 1 through the hinge 6.

[0030] To retract or deploy the rope ladder, flip the electromagnetic platform panels 2 on either side of the channel steel panel 1 90° and place them against the channel steel panel 1. Turn on the electromagnetic switch on the electromagnetic platform panel 2. The electromagnetic force will securely attach the electromagnetic platform panels 2 to the electromagnetic channel steel 3. Place the device on the deck and turn on the electromagnetic switch on the electromagnetic channel steel 3. The channel steel will securely attach to the deck, and the electromagnetic activation indicator light 4 will illuminate. The rope ladder can then be retracted or deployed. To retract the rope, insert the steps of the ladder into the channel steel and pull the ladder toward the ship, replacing each section as it is pulled in. The ladder is secured to the channel steel, allowing crew members to rest and adjust their positions during the retraction process. Furthermore, crew members operate from behind the channel steel, providing some protection.

[0031] When the rope ladder is in place: see Figure 8, turn off the electromagnetic suction force on the electromagnetic suction platform panel 2, unfold the electromagnetic suction platform panel 2, turn on the electromagnetic suction force on the electromagnetic suction platform panel 2 again to attract and fix it to the long side of the channel steel panel 1; turn off the electromagnetic suction force of the electromagnetic suction channel steel 3, turn the box body downward and place the electromagnetic suction channel steel 3 and the ordinary channel steel in the gap between the rope ladder pedals; turn on the electromagnetic suction force of the electromagnetic suction channel steel 3 again, so that the electromagnetic suction channel steel 3 is adsorbed on the deck; at this time, the channel steel panel 1 and the unfolded electromagnetic suction platform panel 2 are used as the boarding platform of the rope ladder.

[0032] The utility model has several key points: the rope ladder is fixed by using electromagnetic suction groove steel; the electromagnetic suction groove steel can be used as a boarding platform in a flipped state; the platform on the groove steel is unfolded to widen the platform width.

[0033] When the device is placed vertically, it can be used as a protective device for the crew, ensuring the safety of the crew; when the device is placed horizontally, it can be used as a platform to prevent people from being tripped by the rope ladder, ensuring the safety of people boarding. This device allows the crew to rest and adjust at any time when retracting or releasing the rope ladder, avoiding the occurrence of emergencies and ensuring the safety of the operating crew; the device is easy to operate.

[0034] The above are preferred embodiments of the present invention. Ordinary technicians in this field can also make various changes or improvements on this basis. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection required by the present invention.
