Description

Technical Field

[0001] The utility model relates to the technical field of boarding ladder devices, in particular to a telescopic device for a boarding ladder. Background Art

[0002] When a ship docks at a pier, it is necessary to set up a boarding ladder to facilitate people to get on and off. These boarding ladders are sometimes used by the ship itself, and sometimes need to be provided by the pier. When the pier needs to provide a boarding ladder, the boarding ladder needs to be moved to the position where the ship is docked. The existing boarding ladders also use different types of boarding ladders according to the size of the ship. This requires a larger space to provide the boarding ladder, and a higher space to accommodate longer boarding ladders. However, the existing boarding ladders are not convenient to store or fold. Therefore, when moving different types of boarding ladders, they may collide with other surrounding objects due to being too long or moving horizontally, causing adverse effects. Therefore, in order to further improve the practicality and safety of the boarding ladder, we propose a boarding ladder telescopic device to solve the above problems. Utility Model Content

[0003] The object of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a telescopic boarding ladder device, which provides a telescopic boarding ladder device by arranging sliding grooves and movable grooves on both sides of the ship ladder safety frame, and pushing and pulling the telescopic ship ladder 2 through the action of a multi-stage electric hydraulic rod. During the movement of the telescopic ship ladder 2, the guide rail drives the telescopic ship ladder 1 to move and unfold. When closed, the telescopic ship ladder 1 and the telescopic ship ladder 2 are both stored on the ship ladder safety frame, so that the entire boarding ladder can not only be stored when not in use, but also does not occupy space and a higher spatial position. When in use, it will not be a situation that only shorter models of ladders can be made because it is a movable boarding ladder, resulting in a low adaptability of the boarding ladder. The deployment distance of the telescopic ship ladder 1 and the telescopic ship ladder 2 can also be adjusted according to the actual boarding distance, thereby further improving the safety and practicality of the boarding ladder. The structure of the entire device is also relatively simple, which is convenient for daily maintenance and upkeep.

[0004] The utility model also provides the above-mentioned ship ladder telescopic device, including: a ship ladder safety frame, a sliding groove is provided on the inner side surface of the upper end of the ship ladder safety frame, a moving bar is slidably connected inside the sliding groove, and a telescopic ship ladder 2 is fixedly connected to the front surface of the moving bar, the inner side surface of the ship ladder safety frame is fixedly connected to a multi-stage electric hydraulic rod, the output end of the multi-stage electric hydraulic rod is fixedly connected to one side of the moving bar, the upper end surface of the ship ladder safety frame is provided with a movable groove, the inner side surface of the movable groove is slidably connected to a movable plate, the inner side surface of the movable plate is fixedly connected to the telescopic ship ladder 1, and the upper surface of the telescopic ship ladder 1 is fixedly connected to a guide rail.

[0005] According to the telescopic boarding ladder device of the present invention, a connecting block is slidably connected to the upper surface of the guide rail, and the top end of the connecting block is fixedly connected to the bottom surface of the telescopic ship ladder 2. It is used to drive the telescopic ship ladder 1 to move when the telescopic ship ladder 2 moves to one side of the ship ladder safety frame.

[0006] According to the telescopic boarding ladder device of the present invention, a movable block is fixedly connected to the bottom surface of the movable plate, and a limit stopper is fixedly connected to the upper surface of the telescopic boarding ladder 1. The limit stopper is connected to the other end of the guide rail to prevent the telescopic boarding ladder 1 from detaching from the boarding ladder safety frame when it is extended.

[0007] According to the telescopic device for a boarding ladder of the present invention, a limit plate is fixedly connected to the rear surface of the ladder safety frame, and the limit plate and the moving block are at the same horizontal position, so as to play the role of limiting and fixing.

[0011] Beneficial effects: By arranging sliding grooves and movable grooves on both sides of the ship ladder safety frame, and pushing and pulling the telescopic ship ladder 2 through the action of a multi-stage electric hydraulic rod, during the movement of the telescopic ship ladder 2, the guide rail drives the telescopic ship ladder 1 to move and unfold. When closed, the telescopic ship ladder 1 and the telescopic ship ladder 2 are both stored on the ship ladder safety frame, so that the entire boarding ladder can not only be stored when not in use, but also does not occupy the site and a higher space position. When in use, it will not be a situation that only a shorter model of ladder can be made because it is a movable boarding ladder, resulting in a low adaptability of the boarding ladder. The unfolding distance of the telescopic ship ladder 1 and the telescopic ship ladder 2 can also be adjusted according to the actual boarding distance, thereby further improving the safety and practicality of the boarding ladder. The structure of the entire device is also relatively simple, which is convenient for daily maintenance and upkeep. BRIEF DESCRIPTION OF THE DRAWINGS
