[0002] As a crucial connection between ships and the shore or dock, boarding ladders play a vital role in the safety and convenience of ship operation, maintenance, and cargo loading and unloading. Boarding ladders are mostly fixed or integral types; while these designs offer stability, they also present challenges such as difficult handling, cumbersome installation, and poor flexibility.

[0003] For example, patent CN119160333A mentions a boarding ladder, which relates to the field of marine equipment technology. It includes a boarding ladder body, an overlapping part, and a movable step. The boarding ladder body includes a step part and a main base frame made of carbon fiber. The step part is laid on the main base frame and can be detached from the main base frame. The overlapping part is installed at the bottom of both ends of the main base frame for overlapping onto the deck and the dock, respectively. One end of the movable step is connected to the side of the overlapping part away from the main base frame, and the other end can be placed on the deck or the dock.

[0004] The aforementioned boarding ladder uses fixed wheel frames on both sides of the main body, with rollers installed at the bottom of the wheel frames. When the boarding ladder is used in conjunction with a ship or dock, one side of the boarding ladder is set on the ship's side and the other side is placed on the dock. However, the height of the ship's side and the dock often differ due to factors such as water depth and the ship's draft. This can cause instability on both sides of the boarding ladder when it is placed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an adjustable boarding ladder that is convenient for stable placement.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an adjustable boarding ladder, the innovation of which lies in: including

[0007] A boarding ladder body includes a base frame, guardrails, and steps. There are two guardrails, which are vertically connected to both sides of the base frame. The steps are located between the two guardrails and laid flat on the base frame. A hinge and a support are connected to both sides of the base frame along its long axis. The hinge includes a hinge seat, one side of which is fixedly connected to the base frame and the other side is hinged to the ship's side. The support includes a pair of support plates connected to both sides of the base frame in the width direction, and the support plates are hinged to the base frame. Two support rollers are installed on the support plates and are defined as the first support roller and the second support roller, respectively. The size of the first support roller is larger than that of the second support roller.

[0008] A wiring auxiliary assembly is installed on both sides of the main body of the boarding ladder. The wiring auxiliary assembly includes several wiring rods distributed on both sides of the base frame. Each wiring rod is an L-shaped rod composed of a horizontal rod and a vertical rod. The wiring rod and the base frame together form a limiting space for cable laying.

[0009] Furthermore, the base frame is arc-shaped, and the arc-shaped opening of the base frame faces downward.

[0010] Furthermore, the base frame includes a pair of first crossbars and several longitudinal bars connected between the two first crossbars. An inclined first diagonal bar is also connected between two adjacent longitudinal bars, and the inclination directions of the two adjacent first diagonal bars are opposite.

[0011] The guardrail includes a second horizontal bar located above the base frame and several vertical bars connected between the second horizontal bar and the first horizontal bar. A second diagonal bar is also provided between two adjacent vertical bars, and there are two second diagonal bars between two identical vertical bars, which are distributed in an X shape.

[0012] The pedal is a hollow pedal.

[0013] Furthermore, the top of the guardrail is also equipped with a lifting lug.

[0014] The advantages of this utility model are as follows: The boarding ladder in this utility model is installed by setting hinges and supports on both sides of the base frame. The hinges ensure stable installation on one side of the boarding ladder, while the supports cooperate with the dock ground to provide stable support, thereby ensuring the stability of the boarding ladder. The design of the wiring auxiliary component is to cooperate with the base frame by adding wiring poles on both sides, thereby forming a limited space for cable laying. This facilitates the unified laying of lines and makes line management easier when the ship and the shore power system of the dock need to be powered after the ship is docked.

[0015] The design of the two support rollers, using a first support roller and a second support roller of different sizes, is to better support the main body of the boarding ladder when there is a height difference between the ship's side and the dock, thus ensuring the stability of one side of the main body of the boarding ladder.

[0016] The underframe adopts an overall arc-shaped design, which, compared to a straight underframe, can better adapt to ship sides and docks with height differences, providing more stable support and improving the comfort and stability of the support.

[0017] The design of the lifting lugs on the railing is to facilitate the subsequent hoisting and movement of the entire boarding ladder. Attached Figure Description
