Description

Technical Field

[0001] The utility model relates to the technical field of boarding ladders, in particular to a boarding ladder with an anti-bumping structure. Background Art

[0002] A boarding ladder is a device used to connect between a ship and a dock, usually for passengers and crew to board or leave the ship. It usually consists of a series of steps that can be fixed to the side of the ship or the dock to ensure safe boarding and exiting. Boarding ladders play an important role in ships and the shipping industry, allowing people to enter and exit the ship easily and quickly.

[0003] In the shipbuilding industry, the design and application of boarding ladders has always been an important link. At present, most boarding ladders adopt a fixed design and are extended by telescopic control. This design mainly relies on the extension of the drive equipment, however, this method has some shortcomings.

[0004] First, the use of a boarding ladder with a retractable drive device will increase maintenance and operation costs. Since the drive device is easily subject to wear and tear, it needs to be regularly maintained and replaced. This will lead to an increase in the cost of use and bring certain pressure to the operation of the enterprise. Secondly, this type of boarding ladder is not very stable and has a poor anti-bumping effect.

[0005] In addition, the stability of the boarding ladder is also affected by the telescopic performance of the drive device. In actual use, due to the limitation of the telescopic speed of the drive device, the extension and retraction process of the boarding ladder may become slow, affecting the efficiency of use. In addition, the drive device may fail during the telescopic process, causing the boarding ladder to fail to work properly, further affecting the normal operation of the ship.

[0006] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a boarding ladder with an anti-bumping structure. Utility Model Content
