Embodiment Construction
[0031] The present invention will be further described below with reference to the accompanying drawings.
[0032] combined with Figure 1-2, The folding ladder group is composed of straight ladder 5, spiral ladder 6 and ladder group support 7. The straight ladder 5 is composed of a number of straight ladder pedals 504 and a straight ladder guardrail. The straight ladder guardrail is composed of a first straight ladder guardrail support rod 501 and a second straight ladder guardrail support rod 502. The second straight ladder guardrail support rod 502 and the first straight ladder guardrail support rod 501 of the rear straight ladder guardrail are connected by a sliding rod 507 through the boss connecting hole 506, and the bottom of the straight ladder guardrail is connected by a connecting pin 508 It is fixed on both sides of the ladder pedal 504 and the installation height of the outer guardrail is higher than that of the inner guardrail. When the foldable ladder group is s...

The invention discloses a modular foldable marine embarkation device which comprises at least two units of folding ladder sets, a login platform and a storage module. The folding ladder group comprises a straight ladder, a spiral ladder and a ladder group supporting structure; the vertical ladder and the spiral ladder are connected at the conversion position, when no more than two folding ladder sets are used, the first folding ladder set is connected with the storage winch through the supporting frame connecting hole by means of the ladder set supporting frame cable, and the second folding ladder set is fixedly connected with the login platform through the supporting frame mounting hole; when more than two folding ladder groups are used, the first two folding ladder groups are connected with the storage winch through the support frame connecting holes by utilizing the ladder group support frame cables, and the third to the last but one folding ladder group are connected to the corresponding overhead unit pedals through the pedal connecting holes by utilizing the vertical ladder pedal connecting ropes; and the final unit folding ladder group is fixedly connected with the login platform through the support frame mounting holes. The occupied space is small, and the platform type can be replaced by modularization according to the use scene.
Description
technical field [0001] The invention belongs to the technical field of sea boarding and escape, and particularly relates to a modular and foldable sea boarding device. Background technique [0002] The marine boarding and escape system is an indispensable device for offshore ships, platforms and other facilities, and is used for daily personnel boarding and emergency evacuation in unexpected situations. The structural design of the marine boarding and escape system has a huge impact on the boarding and evacuation efficiency of personnel. Most of the marine boarding and escape systems used at this stage are fixed ladders or rubber inflatable slides that take up a lot of space, and inflatable slides made of rubber and other materials are easily punctured by foreign objects, posing potential safety hazards. Therefore, there is a need for more reliable marine embarkation and evacuation equipment. [0003] The technical solution disclosed in Chinese patent CN201922008106.7 is a...
