DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0033] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0034] like Figure 1-8 As shown, a surface repair processing device for an electric control cabinet comprises: a base 1, a gantry 2 connected to the base 1, a horizontal support plate 3, at least one Z-shaped mounting arm 4 whose horizontal lower end is mounted on the base 1 and fixedly connected to the lower surface of the support plate 3, a downward pressing repair unit mounted on the top of the gantry 2 and located directly above the support plate 3, and an auxiliary support unit mounted on the base 1 and located below the support plate 3;

[0035] The auxiliary support unit includes a horizontal support plate 5 located directly below the support plate 3 and capable of moving vertically upward to support the electric control cabinet. The downward pressure repair unit includes a horizontal pressure plate 6 located directly above the support plate 3. The vertical middle part of the mounting arm 4 is located directly below the side of the support plate 3.

[0036] In the above technical solution, when it is necessary to repair the deformed part on the surface of the electric control cabinet, the deformed side wall of the electric control cabinet is brought into contact with the upper surface of the support plate 3, and the pressing plate 6 in the pressing repair unit is moved vertically downward. The pressing plate 6 is pressed on the side wall of the electric control cabinet to repair the concave part to make it flat; if the area of ​​the deformed part of the electric control cabinet is large or the number is large, after the pressing plate 6 is pressed down once, the position of the electric control cabinet can be adjusted, and the pressing plate 6 is pressed down again for repair.

[0037] The function of the support plate 5 is to support the electric control cabinet. The height of the support plate 5 can be adjusted according to actual conditions. After adjusting the height, the support plate 5 can support the electric control cabinet. At this time, the deformed side wall of the electric control cabinet is located above the support plate 3 but does not contact the support plate 3. At this time, it is convenient for the electric control cabinet to adjust its position so that the deformed part on the deformed side wall of the electric control cabinet moves to just above the support plate 3; the support plate 5 moves downward again to separate from the electric control cabinet. The electric control cabinet moves downward under the action of gravity, and the deformed side wall will contact the support plate 3. At this time, the pressing plate 6 moves downward to repair the deformed part of the deformed side wall; after the pressing plate 6 is pressed down and reset, the support plate 5 moves upward to support the electric control cabinet, so that the electric control cabinet is separated from the support plate 3. At this time, the position of the electric control cabinet can continue to be adjusted and the repair can continue.

[0038] The support plate 5 lifts the electric control cabinet and separates it from the support plate 3, which is convenient for adjusting the position of the electric control cabinet and can also prevent the support plate 3 from scratching the inner wall of the electric control cabinet during the movement.

[0039] Because the vertical middle part of the mounting arm 4 is located directly below the side of the support plate 3, the mounting arm 4 can be staggered from the support surface of the support plate 3. When the side wall adjacent to the electric control cabinet and the cabinet door is deformed, the deformed side wall of the electric control cabinet contacts the upper surface of the support plate 3, and the other side wall of the electric control cabinet opposite to the deformed side wall can be moved to the bottom of the support plate 3. The Z-shaped mounting arm 4 can free up space under the support plate 3 so that the support plate 3 can contact any side wall of the electric control cabinet, thereby repairing any side wall of the electric control cabinet.

[0040] In a preferred embodiment of the invention, the support plate 3 and the pressing plate 6 are both square, and a strip-shaped mounting seat 7 is fixedly fitted on each edge side wall of the support plate 3 and the pressing plate 6.

[0051] In a preferred embodiment of the invention, the auxiliary support unit also includes a horizontal sliding plate 20 vertically slidably connected to the base 1, a manual height adjustment mechanism mounted on the sliding plate 20 and connected to the support plate 5, at least one connecting rod 21 hinged at an inclined upper end to the lower surface of the sliding plate 20, a sliding arm 22 horizontally slidably connected to the base 1 and hinged at an inclined lower end of the connecting rod 21, and a horizontal second driving push rod 23 mounted on the base 1 and with a piston rod connecting the sliding arm 22.

[0052] In the above technical solution, the distance between the sliding plate 20 and the support plate 5 can be adjusted by a manual adjustment mechanism so that the height of the support plate 5 can be adapted to the electric control cabinet; after the manual adjustment mechanism is adjusted, the second driving push rod 23 will push the sliding arm 22 to slide, thereby pushing the sliding plate 20 to slide vertically upward through the connecting rod 21, preventing the electric control cabinet from being on the support plate 5, at this time, the deformed side wall of the electric control cabinet is separated from the support plate 3; when the second driving push rod 23 drives the sliding arm 22 to slide back to its original position, the sliding plate 20 is driven downward by the connecting rod 21, and the support plate 5 moves downward and separates from the electric control cabinet, at this time the support plate 3 will contact the electric control cabinet.

[0053] In a preferred embodiment of the invention, the manual height adjustment mechanism includes at least one pair of X-shaped deformation frames 24 arranged at intervals and hinged in the middle, a hinged rod 25 with both ends respectively connected to one end of a pair of X-shaped deformation frames 24, a threaded sleeve 26 sleeved on the hinged rod 25, a horizontal threaded rod 27 threadedly passing through the threaded sleeve 26 and assembled on the sliding plate 20 through axle seats at both ends, and a hand wheel 28 assembled on one end of the threaded rod 27, and the sliding plate 20 and the support plate 3 are connected through a pair of X-shaped deformation frames 24.
