[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a hull rust removal device of the utility model comprises a vertical plate 4 and a base 1 arranged on one side of a guardrail 7, an electric push rod 2 is vertically installed on the base 1, a horizontal plate 3 is installed on the piston rod of the electric push rod 2, the horizontal plate 3 is movably connected to the vertical plate 4, a rubber layer 5 is installed on the side surface of the vertical plate 4 facing the guardrail 7, a metal brush layer 6 is installed on the outer surface of the rubber layer 5, the metal burr layer is pressed and arranged on one side surface of the guardrail 7 through the rubber layer 5, a plurality of spring pieces 9 are installed on the horizontal plate 3, and a limiting plate 8 is installed on the end of the spring piece 9 away from the horizontal plate 3, and the limiting plate 8 is sleeved on the guardrail 7.

[0023] In this embodiment, a rotating shaft 14 is vertically installed on the top surface of the vertical plate 4, and a sealed bearing is embedded and installed on the bottom surface of the horizontal plate 3 opposite to the rotating shaft 14, and the other end of the rotating shaft 14 is installed in the inner ring of the sealed bearing.

[0024] In this embodiment, a plurality of positioning grooves are provided on the top surface of the vertical plate 4, and positioning columns 10 are provided in each of the positioning grooves. One end of the positioning columns 10 extends to the outside and is arranged on both sides of the horizontal plate 3. The distance between the positioning columns 10 matches the width of the horizontal plate 3. A compression spring is installed at the other end of the positioning column 10, and the other end of the compression spring is installed on the inner wall surface of the positioning groove. The cross-sections of the positioning groove and the positioning column 10 are both arranged in a rectangular structure.

[0025] In this embodiment, a plurality of universal wheels 13 are mounted on the bottom surface of the base 1, and a counterweight block 12 is mounted on the top surface of the base 1. The counterweight block is made of metal material to increase the stability of the device.

[0026] In this embodiment, the spring pieces 9 are all metal spring pieces 9, which increase the firmness and elasticity of the spring pieces and enable the limiting plate to lean against the guardrail better.

[0027] In this embodiment, a handle 11 is installed on the top surface of the horizontal plate 3, and the device can be pushed by the handle so that the metal brush layer can move along the guardrail.

[0028] In this embodiment, the limit plates 8 are all arranged in a "C"-shaped structure, and a plurality of ball grooves are arranged on the inner ring surface of the limit plates 8. Balls are movably installed in the ball grooves. Parts of the balls extend to the outside along the openings of the ball grooves and contact the outer wall surface of the guardrail 7. The openings of the ball grooves are smaller than the diameter of the balls. The friction between the limit plates and the guardrail is reduced by the balls, so that they can move better along the guardrail.

[0029] When in use, the height of the vertical plate can be adjusted according to the height of the guardrail. When adjusting, the electric push rod is directly started to extend or retract the piston rod of the electric push rod. The movement of the piston rod drives the horizontal plate, the vertical plate, the rubber layer and the metal brush layer until the metal brush layer can be arranged parallel to one side of the guardrail. At this time, the spring piece can be lifted upward and the base can be pushed toward the guardrail. The movement of the base drives the cylinder, the horizontal plate and the vertical plate. The movement of the vertical plate drives the rubber layer and the metal brush layer until the metal brush layer is against one side of the guardrail, and the elasticity of the rubber layer can wrap the metal brush layer on one side of the guardrail. After releasing the spring piece, the limit plate can be moved downward by the rebound of the spring piece, so that the limit plate can be sleeved on the top of the guardrail. The guardrail can be limited to the left and right by the limit plate, so that the device can only move along the guardrail.

[0030] Among them, after the rust removal on one side of the guardrail is completed, the limit plate can be lifted again to make the vertical plate away from the guardrail. After moving away, the positioning column can be pressed down. After losing the obstruction of the positioning column, the vertical plate can rotate around the rotating shaft so that the metal brush layer on the vertical plate can be set inward. At this time, the vertical plate can be lifted upward by the electric push rod so that the vertical plate can be moved to the outside of the guardrail, and after moving toward the guardrail, the metal brush layer can contact the outer side of the guardrail, thereby completing the rust removal operation on both sides of the guardrail.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
