Wharf ship boarding ladder capable of being adjusted all-directionally and automatically

Abstract

The invention discloses a wharf ship boarding ladder capable of being adjusted all-directionally and automatically. The wharf ship boarding ladder includes a landing platform, a ship boarding inclinedladder and a ship boarding platform. The top of the landing platform is provided with a landing supporting platform. Two straight lines on both sides of the landing supporting platform are provided with rolling wheel bearing guiding rails. The rolling wheel bearing guiding rails are internally provided with moving platforms. The two sides of each moving platform are provided with rolling wheel bearings to make the moving platform only be capable of sliding front and back along the rolling wheel bearing guiding rails on the landing supporting platform without being separated from the landing supporting platform. One end of the ship boarding supporting platform is hung out of a gunwale and is connected with the upper portion of a 7-shaped rotation shaft in a hinged mode. The 7-shaped rotation shaft can movably rotate without being separated from the ship boarding supporting platform. The other end of the ship boarding supporting platform is provided with supporting legs and ladder stepson the lower side, and is provided with a ballasting object to press the ship boarding supporting platform and to be used for firming the whole ship boarding platform. The wharf ship boarding laddercan eliminate rocking caused by irregular sway of a ship automatically to make the ship boarding ladder always keep relatively stable; safety of ladder boarding of people is increased; and the servicelife of the ship boarding ladder is prolonged.

Description

technical field [0001] The invention relates to the technical field of wharf boarding ladders, in particular to a wharf boarding ladder that can be adjusted automatically in all directions. Background technique [0002] When a ship is docked at a dock for construction or repairs, boarding ladders are often used to disembark and disembark personnel. When the ship is moored at the dock, it will be shaken and swayed all the time under the influence of wind and waves. This is the most unfavorable factor for the safety of people getting on and off the ship and the wear and tear of the ladder and the ship when using the boarding ladder. In order to ensure the convenience and safety of people getting on and off the ship, the design of the boarding ladder needs to consider how to eliminate the influence of the ship's shaking on the ladder, simplify the operation of boarding the ladder, so as to ensure the safety of people when getting on and off the ladder, and save time and cost ,...

AI Technical Summary

Problems solved by technology

[0006] 1. A simple boarding ladder in the form of a springboard. This kind of boarding ladder has a single structure and takes up the smallest space, but it has no offsetting effect on the ship's shaking.

[0007] 2. Equipped with boarding ladders that can be adjusted automatically in six directions. This kind of ladder adopts a hinged form that can greatly alleviate the influence of ship sway on the ladder. It can automatically adjust the swing in six directions, front, rear, left, right, up, down, but it cannot completely eliminate ship irregularities. The swing of the ladder will still cause wear and tear during the use of the ladder, which will affect the service life of the boarding ladder

[0008] 3. A complex boarding ladder equipped with various equipment such as motors. This kind of ladder has a high degree of intelligence, but it takes up a lot of space, has a complex structure, and high production costs

[0009] 4. One end of some boarding ladders is welded to the hull, which will increase the workload of welding and dismantling, and also need to repair the welding position of the hull
