In this embodiment, the plurality of driving wheels 35 facilitate the movement of the movable housing 1 by the operator, and improve the lancing efficiency.
The working principle of the pavement quick joint cutting device is as follows: in the state shown in fig. 5, the first motor 6 is started, the double-groove belt pulley 7 is driven to rotate by the rotation of the output shaft of the first motor 6, and then the cutting disc 5 is driven to rotate at a high speed by the transmission of the belt and the first belt pulley; then, the second motor 8 is started, the rotation of the output shaft of the second motor 8 drives the threaded rod 9 to rotate, the threaded block 10 moves downwards along the surface of the limiting rod 11 in the rotation process of the threaded rod 9 and under the limiting of the limiting rod 11, so that the first movable inner shell 3 slides downwards, and the cutting disc 5 is driven to gradually move downwards to cut a road surface; when the cutting disc 5 moves down to a proper position, the motor II 8 is closed, the cutting disc 5 stops moving in a limiting way, and then the movable housing 1 is pushed to move linearly, so that the lancing operation of the pavement is completed; after the lancing is finished, only the motor II 8 is started again, and the cutting disc 5 is driven to move upwards to reset and separate from the road surface by the reverse rotation of the output shaft of the motor II 8. In the slitting process of the cutting disc 5, the water body in the water storage tank 12 is conveyed down through the first water conveying hose 14 and the hard pipe 15 by starting the water pump 13, and is sprayed out to the two sides of the cutting disc 5 by the two spray heads 16 respectively, so that the cutting disc 5 is cooled, the cutting disc 5 is prevented from being deformed due to high temperature, irregular slitting is caused, and sediment on the surface of the cutting disc 5 can be flushed, so that the cutting disc is prevented from being scratched by the sediment.
Simultaneously, through the rotation of the double-groove belt pulley 7 and under the transmission of the belt and the belt pulley II, the rotating plate 20 is rotated, so that the connecting column 21 moves anticlockwise and circularly by taking the belt pulley II as the axle center, as shown in the state of fig. 3 to 5, the connecting column 21 moves anticlockwise and circularly to enable the gear 22 to synchronously move, and under the meshing relationship of the gear 22 and the internal tooth groove 19, the gear 22 moves anticlockwise and simultaneously rotates clockwise; under the transmission action of the first transmission plate 23 and the second transmission plate 24, the first transmission plate 23 and the second transmission plate 24 move to the state shown in fig. 4 firstly, the cleaning plate 28 translates towards the trend position of the cutting disc 5 in the joint, then as shown in fig. 4 to fig. 5, the first transmission plate 23 and the second transmission plate 24 drive the cleaning plate 28 to move upwards to remove sand and stone in the joint, and the sand and stone lose support to fall to two sides of the joint after the cleaning plate 28 moves out of the joint, so that the subsequent cleaning is facilitated; with the continued movement of the gear 22, the cleaning plate 28 moves back from fig. 5 to fig. 3, i.e. moves downward while moving backward to re-enter the seam, and the above process is repeated, so that the seam can be automatically cleaned under the continuous movement of the movable housing 1, and the subsequent glue filling operation is convenient to be normal.
Meanwhile, the sliding plate 27 is driven to transversely reciprocate along the inner wall of the limit groove 26 in the transverse moving process of the second transmission plate 24, when the sliding plate 27 moves to the right to abut against the driving rod 31, the piston 30 is pushed to stretch the spring 32 to slide, and then the water in the water delivery box 29 is discharged through the cleaning pipe 34 under the cooperation of the two one-way valves, so that the road joint after sand cleaning is further flushed. When the slide plate 27 moves leftwards and is separated from the driving rod 31, the piston 30 moves leftwards and is reset under the action of the spring 32, and under the cooperation of the two one-way valves, water in the water storage tank 12 enters the water delivery box 29 through the water delivery hose two 33 to be filled so as to spray water next time.
Step S2, cutting the pavement: the double-groove belt pulley 11 of the pavement rapid lancing device rotates to drive the cutting disc 5 to rotate at a high speed to cut the pavement;
step S3, adjusting the cutting depth: the first movable inner shell 3 slides downwards, so that the cutting disc 5 is driven to gradually displace downwards to cut the pavement; when the cutting disc 5 moves downwards to a proper position, the cutting disc 5 stops moving in a limiting way, the movable housing 1 is pushed to move linearly, the lancing operation on the road surface is completed, and after lancing is completed, the cutting disc 5 is driven to move upwards and reset through the lifting component and is separated from the road surface.
And S4, cleaning the cut expansion joint. In the step S4, the cleaning plate 28 translates toward the trend position of the cutting disc 5 in the slit, the first driving plate 23 and the second driving plate 24 drive the cleaning plate 28 to move upward to remove the slit and bring out sand and stone inside the slit, and the sand and stone lose support to fall down to two sides of the slit after the cleaning plate 28 moves out of the slit, so that the subsequent cleaning is facilitated;
when the slide plate 27 moves to the right to abut against the driving rod 31, the piston 30 is pushed to slide, so that the water in the water delivery box 29 is discharged through the cleaning pipe 34, and the road joint after sand cleaning is further flushed.
