Description

Auxiliary boarding ladder Technical Field The utility model belongs to the technical field of marine components, and particularly relates to an auxiliary boarding ladder. Background In marine climb a hill operations, the safety and applicability of boarding aids is critical. The prior boarding auxiliary ladder is mainly formed by combining a ladder way, a ladder frame and a railing, for example, the boarding auxiliary ladder disclosed in Chinese patent publication No. CN212473825U, but because the ladder way length of the auxiliary boarding ladder is usually fixed, when facing different ship types, ship spacing changes or complex sea conditions, the ladder way with fixed length is difficult to flexibly adapt, thereby possibly causing inconvenient boarding and even potential safety hazards, for example, when the two ship widths are greatly different or the berthing angle changes, the fixed ladder way can not be accurately butted, and the personnel climbing risk is increased. Disclosure of Invention The utility model aims to provide an auxiliary boarding ladder, which solves the problems that the boarding is inconvenient and even has potential safety hazards due to the fact that the length of the ladder path of the auxiliary boarding ladder is usually fixed at present, and the ladder path with fixed length is difficult to flexibly adapt when facing different ship types, ship spacing changes or complex sea conditions.
