Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically a device for detecting surface damage to marine cable lines. Background Technology

[0002] Marine cables, as key carriers of power transmission and signal communication on ships, play an irreplaceable role in the safe and stable operation of vessels. Ships navigate year-round in complex and harsh marine environments, posing severe challenges to cable lines. The high corrosiveness of seawater, variable marine weather conditions, intense ultraviolet radiation, and the ship's own mechanical vibrations and electrical interference can all cause gradual damage to the insulation and protective layers of the cables, leading to serious problems such as leakage and short circuits, endangering the safety of the vessel.

[0003] Currently, robots are used to crawl along cables to inspect them, replacing the traditional method of inspecting ship cables. This allows for comprehensive coverage of all cable lines on the ship. However, due to the different diameters of the cables, the robot's walking mechanism needs to be adjusted, which is cumbersome and increases the workload. This limits the application of the robot. Furthermore, the contact surface between the robot's walking mechanism and the cable is generally a flat or curved surface. When facing cables of different diameters, the walking mechanism cannot make multi-directional contact with the cable, which can easily cause the robot to slip and affect the cable inspection process. Utility Model Content

[0004] Therefore, this utility model proposes a surface damage detection device for ship cable lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface damage detection device for ship cable lines, comprising a frame, a visual inspection mechanism, and multiple adaptive walking mechanisms arranged in an array along the circumference of the frame, wherein the visual inspection mechanism is fixed on the front end face of the frame, and the adaptive walking mechanism includes:

[0006] A support plate, which is fixed inside the cylindrical frame;

[0007] The walking assembly consists of multiple telescopic beams mounted on the support plate, and multiple equidistant flexible crawling feet are fixed on the walking surface of the walking assembly.

[0008] A slide block is adapted to slide against a support plate, and the slide column at the bottom of the slide block is slidably disposed in the slide groove of the support plate.

[0009] Two elastic telescopic rods are provided and arranged opposite each other. The two elastic telescopic rods are respectively inclined and rotatably connected between the walking component and the slide.

[0010] The push cylinder has a fixed end fixed on a mounting base, and the mounting base is fixed on the support plate. The moving end of the push cylinder is fixedly connected to the slide block.

[0011] Furthermore, preferably, each of the telescopic beams is vertically disposed between the walking assembly and the support plate.

[0012] Furthermore, preferably, the walking component includes:

[0013] There are two side panels, which are fixedly connected by connecting columns;

[0014] A large roller is rotatably connected between the left ends of the two side plates;

[0015] A gear, which is rotatably connected between the right ends of the two side plates;

[0016] Multiple small rollers are provided and are rotatably connected between the tops of the two side plates at equal intervals, and the multiple small rollers are located between the gear and the large roller;

[0017] A transmission belt, the inner surface of which is provided with teeth and meshes with a gear for transmission, so that the transmission belt can transmit power between the gear, the large roller and each small roller.

[0018] And an electric motor, which uses a gear module to drive the gears to rotate.

[0019] Furthermore, preferably, the flexible crawling feet include:

[0020] A strip seat is fixed to the surface of the transmission belt. The strip seat has a plurality of equally spaced sliding cavities. The top surface of the strip seat has the same number of sliding holes as the sliding cavities, and the sliding holes are connected to the adjacent sliding cavities.

[0021] The slider is slidably disposed in each of the sliding cavities, and a compression spring is connected between the slider and the inner bottom surface of the sliding cavity;

[0022] And foot posts, each of the sliding holes is slidably connected to the foot post, and the bottom end of the foot post is fixedly connected to the slider.

[0023] Furthermore, as a preferred embodiment, the top of the foot post is configured as a hemispherical shape.

[0024] Furthermore, preferably, a rubber layer is fixed to the top surface of the foot post.

[0025] Furthermore, preferably, the outer diameter of the slider is larger than the diameter of the sliding hole.

[0026] Furthermore, preferably, the tube frame includes:

[0027] The ring frame has two parts, each consisting of a first half-ring and a second half-ring. One end of the first half-ring and the second half-ring are hinged together, and the other end of the first half-ring and the second half-ring are fixed with locking bolts.

[0028] And protective frames, with protective frames connecting both the two first semi-rings and both the two second semi-rings.

[0029] This utility model adopts the above technology and has the following beneficial effects compared with the existing technology:

[0030] In this utility model device, the extension or shortening action of the push cylinder drives each walking component to move in opposite or opposite directions until it adapts to the diameter and length requirements of the cable. When the push cylinder pushes the walking component to move towards the cable surface, each foot on the flexible crawling foot that contacts the cable surface presses tightly onto the cable. During this process, since the cross-section of the cable is generally circular, some of the feet in the middle of the strip seat contact the cable first. Under the continued squeezing action of the walking component, some of the compression springs are compressed, causing the upper half of the foot to gradually retract into the sliding hole until each foot contacts the cable surface, thereby providing multi-directional support points and preventing slippage.
