[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] An embodiment of the present application discloses a device for polishing and removing rust from the surface of a civil air defense door. Example

[0034] Reference Figure 1 and Figure 2 A surface grinding and rust removal device for civil air defense doors includes a frame 1 on which a supporting mechanism for supporting the civil air defense door is provided. In addition, the frame 1 also includes a movable frame 3 and a flat grinding wheel 4, as well as a movable frame 2 5 and a bevel grinding wheel 6.

[0035] Reference Figure 1 and Figure 2 The support mechanism includes a support plate 21 and a plurality of clamping rods 22. The support plate 21 is arranged in the horizontal direction. The frame 1 is provided with a support part, which includes a column 121, a hydraulic cylinder 122 and a plurality of guide wheels 123. The column 121 is located at the lower end of the support plate 21 and is fixedly connected to the frame 1 vertically. The support plate 21 is located at the upper end of the column 121 and is slidably connected to the column 121 vertically. The hydraulic cylinder 122 is installed at the lower end of the column 121 for pushing the support plate 21 to move.

[0036] Reference Figure 1 and Figure 2 The clamping rods 22 are arranged along the circumference of the support plate 21 and are slidably connected to the support plate 21 in the direction toward or away from the center of the support plate 21. The support plate 21 is equipped with a push cylinder 23 for moving the clamping rods 22. After the civil air defense door is placed between the multiple clamping rods 22, the push cylinder 23 drives the clamping rods 22 toward the civil air defense door, so that all the clamping rods 22 cooperate to clamp the civil air defense door in place.

[0037] Reference Figure 1 and Figure 2 All guide wheels 123 are located below the support plate 21. The frame 1 is fixed with a horizontal plate 13 for supporting the rotation of the guide wheels 123. The guide wheels 123 are located at the upper end of the horizontal plate 13 and are rotatably connected to the horizontal plate 13. The rotation direction of the upper end of the guide wheels 123 is consistent with the length direction of the frame 1. The support plate 21 is vertically opened with an avoidance opening adapted for the guide wheels 123. When it is necessary to remove or move the civil air defense door, the support plate 21 is driven downward by the hydraulic cylinder 122, so that the guide wheels 123 gradually pass through the avoidance groove 211 and contact the civil air defense door. When the guide wheels 123 contact the civil air defense door, they support the civil air defense door, thereby separating the civil air defense door from the support plate 21. It is more convenient to move the civil air defense door along the rotation direction of the guide wheels 123, which is conducive to reducing the friction between the civil air defense door and the support plate 21.

[0038] Reference Figure 2 and Figure 3 The movable frame 1 3 includes a lifting plate 31 and two movable seats 32. The lifting plate 31 is located between the two movable seats 32 and can slide in the vertical direction relative to the movable seats 32.

The frame 1 is equipped with a moving member 11 for driving the movable seats 32 to move along the frame 1. The moving member 11 is specifically a motor and a lead screw, which is a commonly used driving mechanism in the field. No further details will be given here. The moving member 11 is provided to achieve the movement of the movable seats 32 along the length direction of the frame 1.

[0039] Reference Figure 2 and Figure 3 When any of the movable bases 32 moves, the lifting plate 31 moves with it. Each of the movable bases 32 is equipped with a lifting motor 33. The output shaft of the lifting motor 33 is connected to a lifting screw 34. The lifting screw 34 vertically passes through the lifting plate 31 and is threadedly connected to the lifting plate 31, driving the lifting plate 31 up or down. The lifting motor 33 can be, for example, a permanent magnet synchronous motor, which is compact, lightweight, and highly efficient.

[0040] Reference Figure 2 and Figure 3All the flat grinding wheels 4 are located at the lower end of the lifting plate 31. The lifting plate 31 is equipped with a driving member 30 for driving all the flat grinding wheels 4 to rotate. The driving member 30 includes a drive motor 301, a plurality of transmission wheels 302, a plurality of transmission belts 303, and a driving wheel 304. The transmission wheels 302 correspond to each flat grinding wheel 4 one by one, and each transmission wheel 302 is rotatably connected to the upper end of the lifting plate 31 and moves with the lifting plate 31. The upper end of the flat grinding wheel 4 is coaxially fixed with a rotating shaft 41. The upper end of the rotating shaft 41 is coaxially fixed with a polygonal rod 42. The polygonal rod 42 passes through the corresponding transmission wheel 302 and is slidably connected to the transmission wheel 302 along the axial direction. Under the transmission action of the polygonal rod 42, when any transmission wheel 302 rotates, the corresponding flat grinding wheel 4 is driven to rotate.

[0041] Reference Figure 3 and Figure 4 The upper end of the lifting plate 31 is provided with a plurality of support blocks 311. The support blocks 311 correspond one to one with the polygonal rods 42. A turntable is coaxially fixed to the upper end of the polygonal rods 42. The support blocks 311 are provided with a rotation groove adapted to the turntable. The turntable is located in the rotation groove and is rotatably connected to the support blocks 311. Furthermore, a bearing is provided between the turntable and the support blocks 311 to reduce the friction between the support blocks 311 and the turntable.

The adjustment member 35 includes a rotating handle 351, an adjustment screw 352, and a plurality of slide bars 353. All slide bars 353 are parallel to each other and fixed perpendicularly to the upper end of the lifting plate 31. All slide bars 353 pass through the corresponding support blocks 311 and are slidably connected to the support blocks 311. The adjustment screw 352 is parallel to the slide bar 353 and is rotatably connected to the lifting plate 31.

[0042] Reference Figure 3 and Figure 4 The adjusting screw 352 passes through the support block 311 and is threadedly connected to the support block 311. Under the support of the slide bar 353, the adjusting screw 352 rotates and drives the support block 311 to move. The rotating handle 351 is fixedly connected to the upper end of the adjusting screw 352. When the rotating handle 351 is rotated, the rotating handle 351 drives the adjusting screw 352 to rotate, thereby causing the adjusting screw 352 to drive the support block 311 to move. The rotating handle 351 is easy to hold, which helps improve the convenience of rotating the adjusting screw 352. Under the limiting effect of the rotating groove, when the support block 311 moves, it drives the polygonal rod 42 and the plane grinding wheel 4 to move, thereby adjusting the vertical height of the plane grinding wheel 4.

[0043] Reference Figure 3 and Figure 4The transmission belt 303 is located between adjacent transmission wheels 302, and the transmission belt 303 is in rolling connection with the transmission wheels 302. Under the transmission action of the transmission belt 303, when any transmission wheel 302 rotates, it drives the other transmission wheels 302 to rotate. The driving wheel 304 is in rotation connection with the lifting plate 31, and the rotation axis 41 of the driving wheel 304 is parallel to the rotation axis 41 of the transmission wheel 302. The driving motor 301 is installed above the lifting plate 31 to drive the driving wheel 304 to rotate. The driving wheel 304 is located on the inside of any transmission belt 303 and is in rolling connection with it. When the driving wheel 304 rotates, it drives the corresponding transmission wheel 302 to rotate through the transmission belt 303, thereby driving all the flat grinding wheels 4 to rotate. When the flat grinding wheels 4 rotate, they grind and remove rust on the flat surface of the civil air defense door.

The driving member 50 includes a rotary motor and a sprocket assembly. The rotary motor is mounted on the upper end of the tilting frame 53 and moves the tilting frame 53. The sprocket assembly is located between the rotary motor and the bevel grinding wheel 6. When the rotary motor is in operation, the bevel grinding wheel 6 is driven to rotate via the sprocket assembly. When the tilting frame 53 rotates, the bevel grinding wheel 6 is also driven to rotate. The support frame 52 is equipped with a tilting member 54 for driving the tilting frame 53.

[0045] Reference Figure 2 and Figure 5 The flip member 54 includes a flip screw 541, a moving block 542, a first rotating plate 543, and a second rotating plate 544.

The first rotating plate is vertically fixed to the end of the rotating shaft 531 away from the flip frame 53. When the first rotating plate swings along the length direction, it drives the rotating shaft 531 to rotate. The second rotating plate is located at the end of the first rotating plate away from the rotating shaft 531 and is vertically connected to the first rotating plate.

[0046] Reference Figure 2 and Figure 5The moving block 542 is vertically connected to the support frame 52 for sliding movement, and the moving plate 2 is vertically connected to the moving block 542 for rotation. When the moving block 542 moves, it drives the moving plate 2 to rotate, and then drives the moving plate 1 to swing through the moving plate 2.

The support frame 52 is fixed with a straight plate 521 for supporting the rotation of the flip screw 541. When the flip screw 541 is rotated, the flip screw 541 drives the moving block 542 to move, so as to drive the flip frame 53 to rotate through the moving block 542, the rotating plate 1 543 and the rotating plate 2 544, so as to realize the change of the predetermined angle of the bevel grinding wheel 6, so as to facilitate the grinding of the bevel of the civil air defense door by the bevel grinding wheel 6, which is conducive to improving the convenience of grinding the civil air defense door.

[0047] The implementation principle of this embodiment is: two sets of independent grinding devices are set up, and the plane grinding wheel 4 is driven by the movable frame 1 3 to grind the plane of the civil defense door. Then, by adjusting the flip screw 541, the flip frame 53 is adjusted to an angle suitable for the inclined surface of the civil defense door, and the support frame 52 and the inclined surface grinding wheel 6 are driven to move by the movable frame 2 5, and the inclined surface of the civil defense door is grinded by the inclined surface grinding wheel 6, which is conducive to improving the convenience of grinding the civil defense door.
