Description

Automatic shipborne gangway ladder that breaks away from

Technical Field

The utility model belongs to the technical field of auxiliary equipment of vehicles, and particularly relates to an automatic-disengaging shipborne gangway ladder.

Background

The gangway ladder is a movable ladder which is arranged on two sides of a ship and is used for passengers to get on or off the ship or for maintaining the ship body, and the gangway ladder is made of wood or metal. Comprises an upper platform, a lower platform, a ladder frame, a ladder step, a railing armrest, a hanging ladder device and the like. The ship is lifted when sailing, folded and stored on the deck, and put down and hung on the side when in use. The gangway ladder device is generally used for passenger ships and other various large and medium-sized ships.

In marine environments, fan maintenance and boarding of vessels face stability and safety challenges. Traditional gangway ladder is easily affected by fluctuation of waves under the condition of large waves, and therefore movement and vibration are caused, and difficulty is brought to maintenance of fans and boarding personnel. Particularly in severe offshore environments, the waves may cause instability to the connection of the gangway, possibly leading to personnel hazards and delays in operation.

Preferably, the clamp comprises a clamp arm; a gasket is arranged on the inner side of the clamp arm; the clamp cylinder is clamped on the fan upright post through the clamp arm; the clamp also includes a follower cylinder and a ball bearing disposed between the aisle and the dock.

Compared with the prior art, the utility model has the beneficial effects that:

1. The personnel safety is ensured: the automatic disengaging function can automatically disconnect the connection with the fan or the ship body under the abnormal condition, so that the safety of personnel is ensured. Particularly, when waves are violent or the ship body suddenly moves, the automatic disengaging function can rapidly disconnect the connection with the ship, so that personnel are prevented from being injured or falling into water;

2. Work efficiency is improved: the wave compensation function of the gangway ladder can reduce the influence of waves on the gangway ladder and the ship, so that personnel and operation can be performed under stable conditions, and the continuity and efficiency of work are improved. People and cargoes can enter and exit the ship more quickly and smoothly without being limited by waves;

3. reducing accidents and losses: the gangway with wave compensation and automatic disengagement functions can reduce accidents and losses during handling. Through the change of self-adaptation wave, the gangway ladder can keep stable operating condition, reduces personnel's that arouse because of the wave and falls down or the circumstances that the goods damaged. Meanwhile, the automatic disengaging function can also avoid accidents and reduce accident risks;

4. Safety and comfort of lifting vessel operations: the wave compensation function of the gangway ladder can reduce the relative motion between the ship and the fan, reduce the shaking sense of personnel in the boarding and disembarking processes, and provide a more stable working platform. This will help to reduce discomfort and exercise fatigue for crew members and handling workers, improving safety and comfort of operation;

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
