In other embodiments, the turnover tile paving mechanism 400 can be detached from the mechanical movable arm 500 and replaced with another mechanism, for example, the turnover tile paving mechanism 400 for paving floor tiles is replaced with a mechanism for paving curb stones, so as to meet different brick paving requirements, and meanwhile, the structures of the lifting mechanism 100, the clamping and pushing mechanism 200 and the conveying mechanism 300 on the frame do not need to be changed, so that the expandability of the invention is stronger.

The working process of the invention is explained in detail below:

first, we stack the tiles 01 on the forks of a forklift, and the front and back sides of the stacked tiles 01 are in contact. Then we put down the warehouse rack 130 to be horizontal and drive the fork truck to transfer the stacked floor tiles to the warehouse rack 130, because the warehouse rack 130 is rotatably connected to the bottom center of the longitudinal lifting rack 102, a space for the fork to advance is formed on both sides of the warehouse rack 130, and the warehouse rack 130 can extend into the open center of the fork when the fork truck is running near the paving device 10 for flat bricks. The forklift unloads the tiles and leaves after driving into position.

The storage rack 130 is provided with a second conveying mechanism 132 of a roller or a belt, and the second conveying mechanism 132 conveys the stacked floor tiles 01 forward onto the lifting plate 103. The lift rods of the lifting devices 120 on both sides of the lifting plate 103 slide upwards, and the lift rods move upwards through the lifting chains 122 to further drive the lifting webs 106 on both sides to move upwards steadily, so as to lift the lifting plate 103 at a height as shown in fig. 3 b.

The clamping device 220 of the clamping and pushing mechanism 200 slides backwards to the rear direction of the vehicle, the clamping plate 225 clamps and fixes the left and right ends of the uppermost floor tile 01, and then the clamping device 220 moves towards the front direction of the vehicle. In the process of forward sliding of the clamping device 220, the second roller 221 slides into the lower lifting rail 213 to lift the height thereof, so that the clamping device 220 slightly lifts the height of the floor tile 01 while driving the floor tile 01 to move forward, thereby preventing the clamped floor tile 01 from scraping the floor tile 01 on the lifting plate 103, and further preventing the appearance of the floor tile 01 from being affected.

When the clamping device 220 slides on the forward rail 210 to the position above the transfer mechanism 300, the two clamping plates 225 are released, and the floor tile 01 falls to the transfer mechanism 300, and the transfer mechanism 300 continues to convey the lying floor tile 01 forward.

After the carriage moves to the designated position of the paving area, the position of the turnover tile laying mechanism 400 is positioned by the positioning mechanism 320, the turnover oil cylinder 434 drives the turnover mechanism 430 to turn over integrally, so that the sawtooth scrapers of the scraping mechanism 432 are in inclined contact with the ground, and then the horizontal telescopic cylinder 406 drives the turnover mechanism 430 to move back and forth integrally on the frame to scrape the ground, as shown in fig. 6 g.

After the floor is leveled, the floor tiles transferred by the transfer mechanism 300 are transferred between the pallet 431-4 and the bracket 431-5 through the supporting plate 407, so that the floor tiles are held by the placing mechanism 431. Then, the turnover cylinder 434 drives the turnover mechanism 430 to turn over integrally, so that the placement mechanism 431 with the brick clamped on the rear side turns over to the front side and becomes a horizontal state, as shown in fig. 6h-6i, then the horizontal telescopic cylinder 406 drives the turnover mechanism 430 to retract, the bracket 431-5 is pulled out from a gap between the floor tile 01 and the ground, and at this time, the floor tile 01 is laid on the ground.

Then, the turnover cylinder 434 drives the turnover mechanism 430 to turn over integrally, so that the rolling wheel contacts with the upper surface of the laid floor tile by turning over of the rolling mechanism 433, and then the horizontal telescopic cylinder 406 drives the turnover mechanism 430 to move back and forth, so that the rolling wheel performs rolling operation on the upper surface of the laid floor tile back and forth, as shown in fig. 6 j.

After the rolling is completed, the horizontal telescopic cylinder 406 drives the turnover mechanism 430 to return to the initial position, and the turnover cylinder 434 drives the turnover mechanism 430 to turn over to a state where the placement mechanism 431 is connected to the conveying mechanism 300 (i.e. to return to the state of fig. 6 e). And then the vehicle body moves to the laying position of the next brick, and two sets of positioning mechanisms are used for positioning and ensuring that the laid brick falls into the designated position.

The mechanical boom 500 is used to provide support for the rollover tiling mechanism 400. When the laying equipment for the flat bricks is in a non-laying working state, the mechanical movable arm 500 slides upwards on the vertical guide rail 501 to drive the overturning brick laying mechanism 400 to leave the ground to suspend, so that the overturning brick laying mechanism 400 is protected; when the paving equipment for the flat bricks moves to a specified position, the mechanical movable arm 500 descends, and the horizontal pushing mechanism 506 drives the supporting leg 530 to horizontally move back and forth so as to adjust the position of the overturning brick paving mechanism 400 at the bottom of the mechanical movable arm 500.
