Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1 and 2, according to a first aspect of the present invention, the present invention provides an overhead painting robot 3 mounted on a crane, including a loading platform 302, a painting robot arm 301, and a level detecting and holding mechanism. Wherein the loading platform 302 is connected with the front end of the upper arm of the crane 1 through a pin-hole, as shown in fig. 1. It is understood that the loading platform 302 and the front end of the upper arm of the crane 1 may be connected by a pin, or may be connected by other means such as an articulated joint.
A painting robot 301 is disposed on the stage 302 for performing a painting operation, as shown in fig. 2. And the horizontal detection and holding mechanism is arranged on the object carrying platform 302 and is used for keeping the object carrying platform 302 horizontal all the time when the suspension arm drives the object carrying platform 302 to ascend or descend. The position requirement (up-down, left-right, front-back) movement of the object carrying platform 3 of the crane 1 saves the position movement function of the high-altitude spraying robot 3, so that the high-altitude spraying robot 3 has the advantages of simpler structure, convenient transportation, flexible use and operation, strong maneuverability and greatly reduced manufacture and use cost.
As shown in fig. 1, when the boom of the crane 1 drives the loading platform 302 to ascend and descend, an included angle between the boom and a horizontal direction (an X-axis direction shown in fig. 1) may be changed, so that the aerial painting robot 3 may incline, which is not favorable for spraying. The horizontal detection and holding mechanism detects the inclination information of the high-altitude spraying robot 3 and keeps the high-altitude spraying robot in a horizontal state all the time, so that smooth execution of spraying operation can be ensured.
Specifically, as shown in fig. 2, the level detecting/holding mechanism includes a level sensor 306, a platform connection suspension beam 303, and a driving arm 305. Wherein, a level sensor 306 is arranged on the carrier platform 302 for detecting the tilt information of the carrier platform 302.
As shown in fig. 2, the first end 303a of the platform connection suspension beam 303 is hingedly connected to the carrier platform 302, and is connected thereto by a rotating shaft 307, so that the first end 303a of the platform connection suspension beam 303 can rotate relative to the carrier platform 302. As shown in fig. 1 and 2, the second end 303b of the platform connecting suspension beam 303 is provided with a lifting lug 310, and the lifting lug 310 is connected with the boom through a connecting pin 2 so as to be integrated with the boom of the crane 1, so that the boom of the crane 1 can stably drive the platform connecting suspension beam 303 and the loading platform 302 to ascend and descend when ascending and descending.
The platform connecting hanging beam 303 can be connected with cranes of various specifications and models by replacing the lifting lugs 310, so that the platform connecting hanging beam is more convenient to use and has a wider application range.
The drive arm 305 is hingedly connected at one end to the carrier platform 302 and at the other end to a connecting arm 309 which is fixed to the second end 303b of the platform connecting suspension beam 303. The actuator arm 305, when extended or retracted, drives the carrier platform 302 to rotate relative to the first end 303a of the platform attachment suspension beam 303.
Preferably, the driving arm 305 is configured as an electric push rod, and the extension and retraction of the electric push rod generates a rotation (pitch) motion between the loading platform 302 and the platform connecting suspension beam 303, so as to control an angle between the first end of the platform connecting suspension beam 303 and the loading platform 302, thereby keeping the loading platform 302 horizontal at all times.
It will be appreciated that the drive arm 305 may also be configured as a pneumatic ram, a rack-and-pinion ram, or a helical ram, among other mechanisms capable of achieving a pushing action.
In addition, the horizontal detection and holding mechanism further comprises an electric cabinet 304 arranged in the loading platform 302, the electric cabinet 304 is respectively connected with a horizontal sensor 306 and a driving arm 305, and the electric cabinet 304 controls the movement of the driving arm according to the inclination information of the loading platform 302 detected by the horizontal sensor 306, so that the loading platform 302 is always kept horizontal.
Specifically, when the boom is raised or lowered, the object carrying platform 302 will tilt accordingly, and at this time, the level sensor 306 installed on the object carrying platform 302 will detect the tilt information thereof and send a signal to the leveling control system in the electric cabinet 304, and after receiving the signal of the tilt degree of the object carrying platform 302, the leveling control system sends a motion instruction to the driving arm 305 (electric push rod) after analyzing and calculating, and controls the electric push rod 305 to extend and retract, thereby adjusting the tilt degree of the object carrying platform 302 to be in a horizontal state all the time.
As shown in fig. 1, the axial direction of the platform connection suspension beam 303 is parallel to the axial direction of the boom so that the driving arm 305 performs angular adjustment. In addition, as shown in fig. 2, the second end of the platform connecting suspension beam 303 is further provided with a connecting arm 309, and the driving arm 305 is hinged with the connecting arm 309.
The spray arm 301 is connected to the electric cabinet 304 in a wired manner so that the electric cabinet 304 can control the spraying operation of the spray arm 301. Because the high-altitude spraying robot 3 has more cables, higher working position and large span of working interval, in order to prevent the occurrence of the problems of cable folding, winding, signal attenuation and the like, the spraying mechanical arm 301 is connected with the electric cabinet 304 by a wire, and the electric cabinet 304 is connected with the ground by a cable so as to provide power for the electric cabinet 304; and the electric control box 304 and the ground control unit adopt wireless remote control.
It should be noted that the high-altitude painting robot 3 and the crane 1 are independent from each other, or may be coordinated to be controlled. Normally, the crane 1 is hydraulically controlled and the aerial painting robot 3 is electrically controlled.
The rear end of the spraying mechanical arm 301 is fixedly connected with the loading platform 302, the front end of the spraying mechanical arm 301 is provided with a spray gun 308, and a coating inlet of the spray gun 308 is connected with a coating outlet of the spraying machine 4 on the ground so as to provide coating into the spray gun 308. Under the control of the control system, the spraying mechanical arm 301 can drive the spray gun 308 to move according to a preset track, so that the preset position of the tall building is sprayed.
As shown in fig. 1, applicator 4 is located on the ground and paint can 5 is located below applicator 4, connecting suction line paint can 5 to applicator 4 via a suction line. The applicator coating outlet a is connected to the spray gun coating inlet B by a feed conduit (not shown) to supply coating to the spray gun 308.
Illustratively, the spray robot 301 is a multi-joint robot, such as a 4-joint robot. It will be appreciated that the spray arm 301 may also be in the form of other arms.
According to a second aspect of the invention, the invention provides a painting method of the overhead painting robot mounted on the crane.

Step 2: the horizontal detection and holding mechanism keeps the high-altitude spraying robot 3 in a horizontal state all the time. Specifically, when the boom of the crane 1 moves up (or down), the object carrying platform 302 tilts along with the boom, the level sensor 306 mounted on the object carrying platform 302 sends a signal to the leveling control system in the electric cabinet 304 after detecting the tilt information, and the leveling control system sends a movement instruction to the electric push rod after receiving the signal of the tilt degree of the object carrying platform 302 and after analyzing and calculating, controls the electric push rod to extend and retract, so that the object carrying platform 302 is adjusted to be in a horizontal state all the time.
And step 3: the crane 1 and the high-altitude spraying robot 3 work cooperatively under the control of the operating system, the working positions of the spraying mechanical arm 301 and the spray gun 308 are adjusted, and after the spraying machine 4 is started, the spraying mechanical arm 301 drives the spray gun 308 to perform spraying work on the building according to a preset track under the control of the control system.
And 4, step 4: after the area is sprayed, the crane 1 changes the position of the loading platform 302 to bring the spraying mechanical arm 301 and the spray gun 308 to the next working position.
