The invention discloses a ramp parking device which comprises a base, a vertical frame and a shaft, wherein the base and one side of the vertical frame are sleeved on the shaft, and a fixed structure which can enable the base and the vertical frame to be unfolded vertically or folded mutually is arranged between the base and the vertical frame. The invention adopts the design of directly pressing the base by tires, thereby increasing the friction between the ramp parking device and the ground, enlarging the resistance and reducing the possibility of gliding downward to enable the use to be more safe. Moreover, when the parking device is not used, the vertical frame rotates around the shaft and can be folded with the base to form a 0-degree frame, so that the parking device can be stored conveniently.

The invention discloses a wall-surface plastered plane real-time monitoring instrument for building construction. The wall-surface plastered plane real-time monitoring instrument comprises an upper cover and a base. The wall-surface plastered plane real-time monitoring instrument is characterized in that the upper cover is provided with a window; the base is provided with a driving gear turntable and a toothed turntable; the driving gear turntable and the toothed turntable are meshed with each other and are further pivotally rotated relative to the base; the driving gear turntable is driven by a miniature motor; the toothed turntable is fixedly provided with a green laser emitting pipe, a red laser emitting pipe and a vertical plate; two side surfaces of the vertical plate are provided with a green lower reflecting mirror and a red lower reflecting mirror respectively; the left side wall of the vertical plate is provided with a screw rod and a nut; the nut is fixedly provided with a green upper reflecting mirror; a green laser emitted from the green laser emitting pipe is reflected through the green lower reflecting mirror and the green upper reflecting mirror in sequence, and then is ejected from the window; the right side wall of the vertical plate is similarly provided with a screw rod and a nut; the nut is fixedly provided with a red upper reflecting mirror; a red laser emitted from the red laser emitting pipe is reflected through the red lower reflecting mirror and the red upper reflecting mirror in sequence, and then is ejected from the window.

The invention discloses an automatic paint spraying device for a round metal disk and a paint spraying method thereof. The automatic paint spraying device for the round metal disk comprises a spray gun bracket, a spray gun, a first servo motor, a second servo motor, a control box, a Z-shaped bracket, an X-axis guide track and a Y-axis guide track, wherein the spray gun and the first servo motor are arranged on the spray gun bracket. The automatic paint spraying device is suitable for spraying paint to the surface of metal with larger mass; during paint spraying, the round disk keeps still, a nozzle and a metal sensor perform X-Y axis plane movement above the round disk; and when the metal sensor detects that a metal object exists below the round disk, the nozzle is opened and can spray paint, and otherwise, the nozzle is closed. When the automatic paint spraying device for the round metal disk is used for spraying paint, the surface of the round disk with larger mass can be conveniently, automatically and uniformly painted, the consumption of energy and paint is reduced greatly, and the device is simple in structure, safe and reliable.
