Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning machines for ship rust removal, in particular to a cleaning machine for ship rust removal. Background Art

[0002] Ship rust removal cleaning machines usually use high-pressure water guns or jet devices, combined with chemical solvents or seawater for rust removal and cleaning. These cleaning machines can remove rust, dirt, seaweed and other substances on the surface of the hull, keep the hull clean and extend the service life of the hull. They can be adjusted according to the needs of different parts of the hull to ensure the cleaning effect while minimizing the impact on the environment. Ship rust removal cleaning machines play a vital role in ship maintenance and help ensure the safe navigation of ships and the long-term use of the hull.

[0003] The current cleaning machines cannot guarantee uniform roughness and glossiness of the parts being flushed, and cannot achieve the rust removal quality of sandblasting for pitting and corrosion layer spots. When using cleaning machines to clean rust spots, dirt and other substances on the surface of the hull, the flushing area of ​​the high-pressure water gun cannot be effectively protected and shielded, resulting in personnel working for a long time. The strong pressure causes splashing water, abrasives and flushed materials, which may cause harm to nearby personnel. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing cleaning machine cannot ensure uniform roughness and gloss of the parts during washing, and cannot effectively protect and shield the washing parts of the high-pressure water gun.

[0005] The utility model solves the technical problem by adopting the following technical solution: a cleaning machine for ship rust removal, comprising a supporting chassis and a high-pressure water gun, a protective mechanism is arranged at the end of the surface of the high-pressure water gun, and a nozzle is fixedly installed at the end of the high-pressure water gun;

[0006] The protective mechanism includes an adjusting groove, a fixing nut, a protective baffle, a fastening screw, a limiting groove, a sliding thread groove block and a threaded hole. The adjusting groove is arranged in the inner cavity of the protective mechanism, and the limiting groove is arranged on the front and rear sides of the inner cavity of the adjusting groove. The sliding thread groove block is clamped and installed on one side of the adjusting groove, and a fixing nut is clamped and installed on the other end of the adjusting groove. A threaded hole is arranged on the top of the fixing nut, and the end of the fastening screw passes through the sliding thread groove block until it is threadedly connected with the threaded hole, and the protective baffle is fixedly installed on the bottom of the fixing nut.

[0007] As a preferred embodiment of the utility model, an electric guide rail is fixedly installed on the left side of the supporting chassis, and a supporting driving slide bar is clamped and installed on the left side of the electric guide rail.

[0008] As a preferred embodiment of the utility model, an electric shaft is provided on one side of the supporting and driving sliding rod close to the electric guide rail, and a protective telescopic plate is fixedly installed on the other side of the supporting and driving sliding rod.

[0009] As a preferred embodiment of the utility model, a limiting slot seat and a support plate are fixedly installed on the right side of the support base in sequence from bottom to top, and the high-pressure water gun is placed on top of the limiting slot seat and the support plate.

[0010] As a preferred embodiment of the utility model, a support frame is sleeved and installed on the outer side of the support base frame, a hook is fixedly installed on the inner side of the support frame near the top, and a connecting water pipe is hung on the surface of the hook.

[0011] As a preferred embodiment of the utility model, a high-pressure water pump is fixedly installed on the top of the supporting chassis, a controller is fixedly installed on the front side of the high-pressure water pump, and a connecting pipe head is provided on the left side of the high-pressure water pump.

[0014] 1. The protective mechanism can effectively block water, abrasives and washed debris, and can form a physical barrier when the high-pressure water gun is working, preventing the splashing water, possible abrasive particles, and washed dirt and other materials from directly splashing into the surrounding area, reducing the impact on operators, equipment and the environment, and improving the safety of the working environment. At the same time, a 70Mpa continuously operating high-pressure water pump and abrasive conveying system are set up, and the rust removal speed can reach 10-18m2 / h. The rust removal surface is Sa2.5 grade, and the abrasive particle size is about 0.5mm. River sand or sea sand can be used. After rust removal, the fine abrasive collides with the surface of the object to form powder, which is convenient for discharge with the water flow without accumulation. The nozzle generates a water wedge effect, wedges into the micro-gap, and expands the rust layer cracks. Due to the effects of this forward strike and tangential wedge strike, coupled with the continuity and clustering of the water jet, the uniform roughness and gloss that are difficult to achieve with traditional methods are achieved, and the rust removal quality of sandblasting can also be achieved for pitting layer spots.
