The PLC controller 3 is electrically connected with the first electric telescopic rod 10 through a conducting wire.

The electric telescopic rod 6 and the first electric telescopic rod 10 are electric push rods of BXTL models.

The working principle is as follows: when the device is used, firstly, two electric telescopic rods 6 are started simultaneously, so that the telescopic ends of the two electric telescopic rods 6 extend to the maximum degree, in the process, the two electric telescopic rods 6 push four universal wheels 8 out of a rectangular cylinder 4 through two sliding plates 7 respectively, at the moment, the four universal wheels 8 uniformly lift the device, at the moment, the device is pushed by a push handle 2, so that the device can be easily moved through the four universal wheels 8, at the moment, the device is pushed to the damaged ceramic tile in a house, the damaged ceramic tile is positioned at the center of a square frame 1, at the moment, the two electric telescopic rods 6 are started, so that the telescopic ends of the electric telescopic rods 6 retract to the original position, at the moment, the four universal wheels 8 retract into the rectangular cylinder 4 again, at the moment, the weight of the device is completely born on the two rectangular cylinders 4, and the device is stably seated on the ground, because the bottom of the rectangular cylinder 4 is provided with the anti-slip mat 9, the anti-slip mat 9 can effectively prevent the device from displacing in the operation process, at this time, when the first electric telescopic rod 10 is started, because the PLC controller 3 is electrically connected with the first electric telescopic rod 10 through a lead, the telescopic length of the telescopic end of the first electric telescopic rod 10 is consistent when the first electric telescopic rod is started each time, and the telescopic length of the first electric telescopic rod 10 in each operation can be adjusted and set through the PLC controller 3, when the telescopic end of the first electric telescopic rod 10 is telescopic, the first square frame 14 can be synchronously pushed and pulled to move in the left and right directions, when the first square frame 14 moves, the cutting disc 42 can be synchronously driven to move, so that the cutting disc 42 can be respectively moved to the positions right and upper ends of the left and right sides of the damaged ceramic tile through two-time operation, when the cutting disc 42 is moved to the positions right and upper ends of the sides of the damaged ceramic tile, the second motor 41 is firstly started, when the first motor 24 is started, the first lead screw 2 drives the first lead screw nut 29 to move downwards, when the first lead screw nut 29 moves downwards, the vertical plate 31 is driven by the first connecting rod 30 to move downwards synchronously, the sliding arrangement of the first T-shaped sliding groove 44 and the first T-shaped sliding block 45 plays a role in guiding the vertical plate 31 in the downward movement process of the vertical plate 31, the vertical plate 31 moves downwards, the second motor 41 and the cutting disc 42 are driven by the L-shaped mounting plate 40 to move downwards synchronously, finally, the bottom end of the cutting disc 42 is contacted with the side end of a damaged tile, as the bottom end of the square positioning rod 34 is embedded into one positioning groove 38 in the middle of the three positioning grooves 38 (as shown in figure 1), the cutting disc 42 is in a vertical state relative to the tile, so that the cutting disc 42 can vertically cut the side end edge of the tile, and at this time, the motor 15 is started, so that the lead screw 16 drives the lead screw nut 17 to move back and forth, when the screw nut 17 moves in the front-back direction, the sleeve 18 is synchronously driven to move through the arrangement of the two first limiting rings 43, when the sleeve 18 moves, the vertical plate 31 and the L-shaped mounting plate 40 are synchronously driven to move, when the L-shaped mounting plate 40 moves along with the movement of the screw nut 17 in the front-back direction, the cutting disc 42 is synchronously driven to move in the front-back direction, so that the cutting disc 42 can vertically cut off the connection between the damaged ceramic tile and the concrete mortar between the adjacent ceramic tiles, then the first motor 24 is started, the cutting disc 42 is lifted to the original position, then the second motor 41 is closed, then a worker holds the handle 32 with one hand and pulls the first handle 37 with the other hand, so that the bottom end of the square positioning rod 34 is separated from the middle positioning groove 38 in the three positioning grooves 38, at the moment, the worker can push the vertical plate 31 in the left-right direction through the handle 32, when the vertical plate 31 is pushed to the left side, the cutting disc 42 is driven to rotate by taking the screw nut 17 as the axis counterclockwise direction, finally, the connecting rod 20 is in contact with the left end face of the sliding groove 19, the first handle 37 is loosened, the bottom end of the square positioning rod 34 is embedded into the leftmost positioning groove 38 under the action of the spring 36, the sleeve 18 is further fixed on the screw nut 17, and because the included angle between the circle centers of every two adjacent positioning grooves 38 is 45 degrees, the vertical plate 31 drives the cutting disc 42 to rotate by 45 degrees in the anticlockwise direction, the vertical plate 31 is pushed to the right side in the same way, the connecting rod 20 is in contact with the right end face of the sliding groove 19, the first handle 37 is loosened, when the bottom end of the square positioning rod 34 is embedded into the rightmost positioning groove 38, the vertical plate 31 drives the cutting disc 42 to rotate by 45 degrees in the clockwise direction, so that the included angle between the cutting disc 42 and a ceramic tile can be adjusted, the cutting disc 42 and the ceramic tile are firstly, the included angle between the cutting disc 42 and the ceramic tile is 45 degrees, and then the second motor 41 is respectively started, The first motor 24 and the motor 15 make the cutting disc 42 incline 45 degrees to cut the broken tiles, then the first motor 24 is started again to make the cutting disc 42 ascend, then the first electric telescopic rod 10 is started once again, so that the cutting disc 42 can move a distance in the left-right direction, then the first motor 24 is started again to make the cutting disc 42 descend and cut the broken tiles until all parts of the broken tiles are cut at equal distances and at equal angles of positive and negative 45 degrees longitudinally, then the cutting disc 42 and the tiles are cut at equal angles of negative and negative 45 degrees longitudinally (as shown in figures 5, 6 and 7), then the device is rotated for 90 degrees, and the broken tiles are cut at equal distances and at equal angles of positive and negative 45 degrees transversely according to the above, at this time, the broken tiles and the concrete at the bottom of the broken tiles can be separated into a plurality of small blocks (as shown in figure 8), at this moment, clear up the work of laying bricks of damaged ceramic tile both can be accomplished to little massive residue, because the whole mode that adopts the cutting of this device comes the damaged ceramic tile cutting fritter, do not need equipment such as electric pick or hammer to go to pound broken damage ceramic tile, so the vibrations that produce are less, can not exert an influence to the peripheral ceramic tile of damage ceramic tile, compare in current brick-lifting mode laborsaving moreover, the new ceramic tile mounting groove bottom after finally clearing up simultaneously is the cockscomb structure, be favorable to later stage concrete mortar and the firm combination of mounting groove bottom.
