Description

Technical Field

[0001] The utility model relates to a port and navigation project, in particular to a vertical ladder for a dock wall. Background Art

[0002] Small and medium-sized vessels often approach and berth near coastal dock walls for berthing or inspection purposes, and crew members often use soft ladders or wall-mounted steel ladders to ascend and descend the dock walls. Traditional soft ladders are easily corroded by seawater and have a short lifespan. Steel ladders are prone to scratches and collisions because the ships are close to the dock walls, which can damage the steel ladders and prevent crew members from entering and exiting smoothly, posing a safety hazard. In addition, to account for the difference in water level caused by high and low tides, the bottom of the steel ladder usually extends downward beyond the bottom of the dock wall for a distance. This extended section is suspended and lacks overall stability. Therefore, when the sea level is low at low tide, the bottom of the suspended lower section of the steel ladder lacks support, resulting in insufficient overall stability.

[0003] Therefore, a vertical ladder for a wharf wall is proposed to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0021] like Figures 1 to 4 As shown, a vertical ladder for a dock wall comprises:

[0022] The mounting groove 1 is a vertical groove opened at the end of the dock wall 7;

[0023] There are two ladder uprights 2 arranged side by side on the left and right sides, and a ladder crossbar 3 is arranged between the two ladder uprights 2; the ladder uprights 2 and the ladder crossbar 3 are both arranged in the installation groove 1;

[0024] The first mounting plate 4 includes a transverse plate 401 and a longitudinal plate 402 that are perpendicular to each other. The transverse plate 401 is fixed to the bottom of the mounting groove 1 by a first bolt 403, and the longitudinal plate 402 is fixed to the ladder upright 2 by a second bolt 404;

[0025] The diagonal brace 5 has one end fixedly mounted on the lower surface of the pier wall 7 and the other end fixedly connected to the ladder upright 2 via a third bolt 601;

[0026] The second mounting plate 6 is arranged horizontally, with one end fixedly connected to the diagonal support rod 5 and the other end fixedly connected to the ladder upright rod 2.

[0027] In the present invention, the main principles are as follows: the mounting groove 1 is the mounting position of the entire ladder, and people go up and down the ladder in the mounting groove 1, thereby avoiding the problem of the wall-mounted steel ladder in the prior art being exposed at the end of the dock wall 7, which is prone to collision with ships and causes damage to the ladder and the ship. Specifically, the ladder uprights 2 serve as the main force-transmitting components of the entire ladder and are arranged side by side in the mounting groove 1, one on the left and one on the right. The ladder crossbars 3 serve as the main load-bearing components of the ladder, and their two ends are fixedly connected to the ladder uprights 2 on both sides, acting as steps. In addition, a first mounting plate 4 is formed by mutually perpendicular horizontal plates 401 and vertical plates 402, which serve as supports for the ladder uprights 2. This allows the ladder uprights 2 to be pushed away from the bottom of the mounting groove 1, leaving space for people to step on. The length of the vertical plates 402 can also determine the distance between the entire ladder and the bottom of the mounting groove 1. One end of the diagonal brace 5 is fixedly connected to the lower surface of the quay wall 7, and the other end is fixedly connected to the ladder upright 2. This creates a triangle with the quay wall 7, the ladder upright 2, and the diagonal brace 5. This effectively reinforces the suspended section at the bottom of the ladder, preventing any wobbling or instability caused by the suspended ladder. A second mounting plate 6, serving as a support plate, is supported between the diagonal brace 5 and the ladder upright 2, further reinforcing the triangle and ensuring its stability.

[0028] As a preferred embodiment, it further comprises a U-shaped handrail 8 , which is embedded in the upper surface of the quay wall 7 with its opening downward and close to the ladder upright 2 .

[0029] This embodiment provides a U-shaped handrail 8 for providing a gripping position when people go up and down the ladder, thereby improving the safety of the process.

[0030] As a preferred embodiment, the ladder upright 2 is provided with a plurality of sleeves 201, which are fixedly connected to the ladder upright 2 by a fourth bolt 9; a U-shaped groove 202 with an opening toward the outside of the ladder upright 2 is also fixed to the outside of the sleeve 201, and the longitudinal plate 402 of the first mounting plate 4 is embedded in the U-shaped groove 202 and fixedly connected to the U-shaped groove 202 by a second bolt 404.

[0031] As a preferred embodiment, a plurality of second mounting plates 6 are evenly distributed along the ladder uprights 2 in the vertical direction.

[0032] In this embodiment, a plurality of second mounting plates 6 are provided to further strengthen the connection between the ladder uprights 2 and the diagonal braces 5 , thereby preventing the ladder uprights 2 from shaking.

[0033] The words "connection" and "fixation" appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.
