[0031] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0032] It should be noted that these and other subsequent drawings are only examples and are not drawn in proportion, and should not be used as a limitation on the actual scope of protection required by the present utility model.

[0033] When the barge 100 docks at the wharf 200, there are potential safety hazards when people board the barge, such as the bumping and displacement of the landing equipment caused by the swell. The existing landing equipment is inconvenient to use and requires multiple people to operate.

[0034] In order to solve the above problems, the utility model provides a boarding ladder, which can be changed from the original multi-person assistance to a single-person independent operation, and can safely complete the boarding operation under high and low tide conditions.

[0035] Reference Figures 1A to 5 As shown, the boarding ladder includes a base 10 , a ladder body 20 and a clamping plate 30 .

[0036] Base 10 refers to 1A and Figure 5 As shown, the base 10 includes two opposite clamping plates 11, and the clamping plates 11 are also provided with movable fasteners 12, which are configured to be able to flip up and down relative to the clamping plates 11. The base is used to ensure the stability of the boarding ladder during operation, connect and support the ladder body, and ensure the safety of the boarding operation. In some embodiments, the base 10 also includes reinforcing ribs 19 and a bottom plate 18.

[0037] The ladder body 20 is rotatably connected to the clamping plate 11. Figure 1A In the illustrated embodiment, the clamping plate 11 further includes an extension portion 13, the extension portion 13 is provided with a strip groove 14, and the ladder body 20 includes a support shaft 22, the support shaft 22 extends into the strip groove 14, and is fastened by bolts. After the bolts are loosened, the support shaft 22 can move up and down along the strip groove 14, thereby adjusting the posture of the ladder body. The support shaft can adjust the state of the boarding ladder according to the height difference between the dock and the barge, and adapt to the needs of climbing operations at different angles and heights.

[0038] In some embodiments, the ladder body 20 can also be divided into a folding portion and a non-folding portion, and the folding portion allows part of the ladder body to be stored in the cavity defined by the pair of clamps 11. For example, the ladder body 20 includes a first ladder body 201 and a second ladder body 202. One end of the first ladder body 201 is rotatably connected to the extension portion 13 of the clamp through a support shaft 22, and the other end is rotatably connected to the second ladder body 202 through a structure such as a pin connection. The second ladder body 202 is set to rotate at an angle of approximately 360° relative to the first ladder body 201. This design allows the ladder body 20 to flexibly adjust its angle, such as Figures 9A-9B shown.

[0039] The card plate 30 is detachably connected to the clamping plate 11, and includes a mounting groove 31 extending inwardly from the edge of the card plate. Figure 1C The mounting groove 31 is located above the clamping plate 11, so that the movable fastener 12 can be folded upward to press the clamping plate 30 onto the clamping plate 11, as shown in FIG. Figure 2 When the hull height is low and the dock height is high, the clamping plate 30 is clamped on the base to limit the excessive rotation of the main body, thereby avoiding capsizing due to the outward shift of the center of gravity during the climbing process of personnel.

[0040] Specifically, Figure 1C and Figure 3 As shown, the clamping plate 11 includes a pair of ear pieces 16, and the movable fastener 12 is connected to the hole axis of the pair of ear pieces 16. Further, the movable fastener 12 includes a first end 121, a second end 122 and a rod body 123, the first end 121 is sleeved on the shaft body 160 connecting the pair of ear pieces 16, and the second end 122 includes a clamping cap 124 threadedly connected to the rod body 123. Loosen the clamping cap 124 and rotate the second end 122 to separate the movable fastener 12 and the clamping plate 30, and remove the clamping plate 30 from the ladder body 20. Reversely rotate the second end 122 to allow the rod body 123 to pass through the installation slot 31, and use the clamping cap 124 to clamp the clamping plate 30 to fix the clamping plate 30 on the ladder body 20.

[0041] It is understandable that the diameter of the rod body 123 is preferably smaller than the width of the installation slot 31 to allow the movable fastener 12 to flip over; the width of the clamping cap 124 is preferably larger than the width of the installation slot 31 to fasten the clamping plate 30.

[0042] In some embodiments, the clamping plate 11 further includes a hollow portion 17 located below the ear piece 16 to allow the movable fastener 12 to be turned downward to a larger angle.

[0043] In some embodiments, the top of the clamping plate 11 includes a first bearing surface 111 and a second bearing surface 112. The second bearing surface 112 is lower than the first bearing surface 111 to form a step structure 113. When the clamping plate 30 is placed on the second bearing surface 112, it is limited by the high step structure 113 formed by the first bearing surface 111. Figure 7 As shown, the clamping plate 30 is clamped on the base 10 .

[0044] The use process of the boarding ladder is specifically described below in conjunction with the accompanying drawings.

[0045] exist Figure 1B In the embodiment, when the barge is in a non-working state, the boarding ladder can be adjusted and the movable clamping plate 30 can be fixed using the clamping cap 124 .

[0046] Figure 6A-6B Shows the operation steps when high-altitude work is required. Fig. 6A As shown, the pressing cap 124 is rotated to remove the card plate 30 from the base 10; Figure 6B As shown, the boarding ladder body 20 is rotated in the clockwise direction V so that the upper end of the ladder body 20 is close to the dock 200; Figure 6C As shown, when the dock 200 is high and the barge 100 is low, the ladder body 20 is rotated to make it lean against the edge of the dock 200; Fig.6D As shown, the card plate 30 is placed on the step structure of the base 10, specifically, on the second bearing surface 112, and the movable fastener 12 is rotated, and the left and right ends of the card plate 30 are fixed with the clamping cap 124, and the card plate 30 can be carried out. Fig. 9A Boarding operations.

[0047] When the barge 100 is high and the dock 200 is low, the pallet 30 is removed, and the boarding ladder is rotated in the clockwise direction V as shown in the figure, so that its end is placed on the ground of the dock 200, and then the movable fastener 12 is rotated to reset and tighten the pallet 30, and the boarding ladder can be carried out. Fig. 9B Boarding operations shown.

[0048] The above-mentioned boarding ladder can effectively enhance the safety of boarding operations, and has a stable structure, is easy and convenient to operate, can be placed on a barge and / or a dock, can be completed by a single person, and can meet the state adjustment and fixation requirements during the boarding process.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0050] Although the utility model is disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the utility model.
