Two guide rails are installed on the upper part of the L-shaped platform. The guide rail near the front of the L-shaped platform is composed of two small guide rails. Both ends are closed with pins. The upper part is also installed with two motors with lead screws, and the other end of the lead screws is matched with two sliding tables, and the two sliding tables are respectively mounted on the two guide rails on the L-shaped platform. The upper part of the platform is also installed with two motors equipped with reducers, which are used to drive the two coaxial winches on the L-shaped platform to drive the L-shaped platform to move up and down. Connected to each other, the outgoing cable is passed through the fixed pulley fixed on the top of the small crane on the top of the building, and the upper part of the L-shaped platform is also equipped with two chains with hooks, and the hooks are connected with the other end of the cable .

The two sliding tables are installed on the sliding table close to the front guide rail of the L-shaped platform and are equipped with a multi-joint mechanical arm, and the other of the two sliding tables is equipped with a paint silo integrated with the counterweight, which is integrated with the counterweight. Driven by the sliding table, the integrated paint silo moves in the opposite direction to the multi-joint mechanical arm at the same speed, which plays the role of balancing the L-shaped platform and loading the paint used for spraying.

The end of the multi-joint robotic arm is equipped with a spray head for spraying paint. The spray head is connected to the paint silo integrated with the counterweight through a pipeline. A visual sensor is installed on the top of the spray head, which can automatically sense after opening. Whether the front is a wall.

The small crane is equipped with 4 steering wheels at the bottom of the small crane base, which can facilitate the small crane to move at will; the small crane base is punched with 4 cylindrical holes for inserting steel pipes for construction sites to fix the small crane On the top of the building; the top of the small crane is equipped with an unbalanced locking device, and the unbalanced locking device is a safety protection device during the operation of the working platform. Balance or other reasons cause one side of the L-shaped platform to slide down, and the unbalanced locking device can automatically and quickly lock the L-shaped platform on the safety rope to stop the L-shaped platform from sliding down.

The beneficial effect of the utility model is that the external wall of the building can be effectively sprayed, the labor safety problem can be effectively solved, the manual labor intensity is reduced, the working efficiency is improved, and the structure is compact, the service life is long, the load capacity is strong, and the working time is not easy. Will make too much movement and will be able to fit almost any wall.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

Aiming at the shortcomings of the existing wall spraying devices, the present invention proposes an automatic spraying mechanism for building exterior wall paint, as shown in Figures 1 to 4, which mainly includes a spraying working device on an L-shaped platform 1 and a spraying device fixed on the top of the building. Fixing the small crane 30 .

The automatic spraying mechanism for building exterior wall paint is equipped with four L-shaped platform steering wheels 27 at the bottom of the L-shaped platform 1, which can facilitate the L-shaped platform 1 to move freely on the ground; 1 The front part is equipped with two suction cups 22, 23. The suction cups 22 and 23 are circular in shape and are used to be adsorbed on the wall during work; two guide rails 2 and 5 are installed on the upper part of the L-shaped platform The two sliding tables 17 move left and right on the guide rails 2 and 5. The guide rail 2 is composed of two small guide rails, and both ends are closed with pins 3 and 24; The two motors 15 and 16 of the lead screws 18 and 20 are used to drive the sliding table 17 to move. One of the two sliding tables 17 near the front of the L-shaped platform 1 is equipped with a multi-joint mechanical arm 19, so The end of the multi-joint robotic arm 19 is equipped with a spray head 26 for spraying paint, for spraying paint when working, and a visual sensor 29 is installed on the top of the spray head 26, which can automatically sense whether the front is a wall after opening the work.
