Description

Technical Field

[0001] The present invention relates to the technical field of municipal construction facilities, and in particular to an automated municipal road brick-paving device. Background Art

[0002] With the development of the current urban construction level, the requirements for municipal roads are getting higher and higher. Sidewalks, squares and other places usually need to be paved with flat floor tiles over a large area. The commonly used method is to lay tiles manually, which has low laying efficiency and high labor costs.

[0003] After searching, the Chinese patent authorization number CN110409262A discloses an automatic brick-laying device for municipal pavement, including a track and a trolley that can move along the track. The frame of the trolley is provided with a mechanical arm, a brick hopper and a sensor. The mechanical arm is connected to a vacuum suction cup, and a scraper with adjustable vertical position is provided under the frame. When performing brick-laying operations, the trolley runs smoothly on the track, and the scraper flattens the sand surface of the area to be laid while the trolley is running. The mechanical arm drives the vacuum suction cup to suck bricks from the brick hopper and lay them on the pavement behind the trolley. The sensor identifies and detects the shape of the bricks and the flatness, gap, height, etc. of the paved surface. The mechanical arm and the vacuum suction cup grab and lay bricks according to the detection signal, and can accurately control the position, height and other indicators of the laid bricks. The above patent has the following deficiencies: the vacuum suction cup on the robot arm can only adsorb floor tiles with smooth surfaces, and most floor tiles have impurities such as mud and sand attached to their surfaces after production and transportation, and the adsorption effect of the vacuum suction cup is poor.
