Description

Technical Field

[0001] The invention relates to the technical field of municipal road construction devices, and in particular to a municipal asphalt concrete pavement construction device. Background Art

[0002] Asphalt concrete pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. It can improve the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable.

[0003] Asphalt concrete pavement may develop cracks during long-term use. There are generally two ways to repair these cracks. One is direct grouting, which is only suitable for cases where the cracks are small. When the cracks are large, the crack position needs to be cut out and new asphalt concrete is re-paved at the cut position.

[0004] Although there are some mechanical slitting devices on the market, these devices can only cut gaps of fixed depth. The Chinese patent with patent application number: 202011210125.9 discloses a road slitting device with adjustable depth, which can adjust the depth of the slit. However, in the process of repairing pavement cracks, it is usually necessary to open cutting slits on both sides of the cracks, and then clear the materials in the cutting area between the cutting slits. The above patent only has a single cutting disc, and can only open a cutting slit on one side of the crack at a time, resulting in low processing efficiency. In addition, the width of the cutting area also has requirements for different degrees of crack propagation. The above patent cannot cut a cutting area of ​​fixed width. After the cutting is completed, the concrete in the cutting area needs to be crushed and cleared using a crushing device, resulting in reduced construction efficiency. Summary of the invention

The PLC controller 51 controls the cutting motor 34 and the crushing motor 44 through the timer 53 to have a first working time T1 and a second working time T2 that run alternately.

When the cutting motor 34 is working, the device moves and the cutting wheel 19 rotates to open the cutting seam R1. When the crushing motor 44 is working, the cutting area R2 is crushed.

[0046] In the second working time T2, the crushing motor 44 rotates N circles. Since the transmission ratio of the two bevel gears in the sixth bevel gear pair 425 is 1:1, the number of heads of the second worm 424 and the number of teeth of the second worm wheel 422 are Z1 and Z2 respectively. When the crushing motor 44 rotates 1 circle, the second worm wheel 422 rotates (Z 1 / Z2) turns, the turntable 418 rotates synchronously (Z 1 / Z2) circle, in the initial state, the second pin 420 is at the top. In one crushing process, the crushing rod 42 needs to be reciprocated and raised once, that is, in one crushing process, the turntable 418 rotates one circle. When (Z 1 / When Z2)*N=1, the turntable 418 rotates one circle during the working time of the crushing motor 44. The working principle of the present invention is:

[0047] First, the spacing of the cutting wheel 19 is adjusted by rotating the double-headed screw 215, and then the forward and reverse switch 214 is used to control the electric push rod 27 to extend or shorten to adjust the height of the cutting wheel 19. At the beginning, the first running wheel 13 and the cutting wheel 19 are in contact with the municipal pavement R. When the cutting wheel 19 rotates, it will enter the municipal pavement R until the second running wheel 16 is in contact with the municipal pavement R and enters the formal working state.

[0048] After the control switch 52 is turned on, the PLC controller 51 controls the cutting motor 34 and the crushing motor 44 to work alternately. When the cutting motor 34 is working, the crushing motor 44 is braked, the device moves and the cutting wheel 19 rotates to complete the opening of the cutting seam R1; then the cutting motor 34 is braked, the device remains stationary, and the crushing motor 44 works to crush the asphalt concrete in the cutting area R2.
