Description

Technical Field

[0001] This utility model belongs to the field of ship repair technology, and specifically relates to a climbing ladder for ship repair. Background Technology

[0002] A ship is a man-made means of transportation that primarily operates in water. Civilian vessels are generally called ships, military vessels are called warships, and small boats are called boats or dinghies; collectively, they are referred to as ships or naval vessels. Internally, they mainly include interior space, supporting structures, and drainage structures, and possess a propulsion system that utilizes external or internal energy sources. Their external shape is generally a streamlined envelope that helps overcome fluid resistance. Materials are constantly updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials primarily include steel, aluminum, fiberglass, acrylic, and various composite materials.

[0003] Currently, most existing ship repair climbing ladders are used by hooking them up. However, because the bottom of the climbing ladder does not have a positioning function, the climbing ladder has poor stability and is prone to shaking or displacement, which affects the stability of maintenance personnel and poses certain safety hazards. Therefore, we propose a new type of ship repair climbing ladder. Utility Model Content

[0004] The purpose of this invention is to provide a climbing ladder for ship maintenance to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a climbing ladder for ship maintenance, comprising a climbing ladder body, sleeves, and suction cups. Sleeves are fixedly installed on both sides of the bottom end of the climbing ladder body. Suction cups are fixedly installed at the ends of the sleeves. The center of the suction cups is sealed to the interior of the sleeves via a through groove. An air hole is provided on one side of the sleeve, communicating with the interior of the sleeve. A piston is slidably disposed inside the sleeve. A piston rod is fixedly installed at the center of one side of the piston. A compression spring is provided on the outer periphery of the piston rod. The two ends of the compression spring are fixedly connected to the inner wall of the sleeve and the piston, respectively. The piston rod extends through the sleeve into the interior of the two vertical bars of the climbing ladder body and is slidably connected to their inner walls. A pull rod groove is provided at the end of the piston rod away from the piston. A first arc-shaped protrusion is provided on the inner wall of the pull rod groove at the end away from the piston. Pull rods are movably disposed inside the two vertical bars of the climbing ladder body. A second arc-shaped protrusion corresponding to the first arc-shaped protrusion is provided on one side of the bottom end of the pull rod.

[0006] Preferably, the top of each of the two vertical bars of the climbing ladder body is provided with a sliding groove, and a lever is provided inside the sliding groove. The lever is fixedly connected to one end of the pull rod.

[0007] Preferably, a limiting baffle is fixedly installed at the bottom of the pull rod, and the length of the limiting baffle is greater than the length of the pull rod groove.

[0008] Preferably, a tension spring is provided at the bottom of the limiting baffle, and the two ends of the tension spring are fixedly connected to the bottom surface of the vertical rod of the climbing ladder body and the bottom of the limiting baffle, respectively.

[0009] Preferably, hooks are provided at the top of the vertical bars on both sides of the climbing ladder body, and the hooks are fixedly connected to the vertical bars on both sides of the climbing ladder body by welding.

[0010] Preferably, a guardrail is provided on one side of the vertical bars on both sides of the climbing ladder body, and the two ends of the guardrail are fixedly connected to the vertical bars on both sides of the climbing ladder body by welding.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By installing suction cups on both sides of the bottom of the climbing ladder body, the suction cups adhere to the vessel. With the help of hooks, the suction cups ensure the stability of the bottom of the climbing ladder body during maintenance. A piston is installed inside the sleeve, which, together with the through groove and air hole, drives the first arc protrusion to move by the second arc protrusion on the pull rod. This drives the piston rod to move, thereby controlling the opening and closing of the air hole to release the suction cups. This design ensures the stability of the climbing ladder body during use while also improving ease of use.

[0013] 2. By setting a limiting baffle at the bottom of the pull rod, the bottom end of the pull rod is limited by the limiting baffle, which prevents the pull rod from coming out of the pull rod groove, causing the first arc-shaped protrusion and the second arc-shaped protrusion to misalign, thus preventing the piston rod from extending and retracting. This effectively ensures the stability during use. Attached Figure Description

A piston rod 8 is fixedly installed at the center of one side of the piston 11. The outer periphery of the piston rod 8 is... A compression spring 12 is provided, with its two ends fixedly connected to the inner wall of the sleeve 4 and the piston 11, respectively. The piston rod 8 extends through the sleeve 4 into the interior of the two vertical bars of the climbing ladder body 1 and is slidably connected to their inner walls. A pull rod groove 9 is provided at the end of the piston rod 8 away from the piston 11. A first arc-shaped protrusion 10 is provided on the inner wall of the pull rod groove 9 away from the piston 11. Pull rods 13 are movably provided inside the two vertical bars of the climbing ladder body 1. A second arc-shaped protrusion 14 corresponding to the first arc-shaped protrusion 10 is provided on one side of the bottom end of the pull rod 13.
