Description
Technical Field
The invention relates to the technical field of pavement maintenance engineering machinery, in particular to slotting equipment suitable for pavement crack repair.
Background
In the process of using the municipal road, especially an asphalt concrete road surface or a cement concrete road surface, bending cracks with different lengths, widths, depths and shapes inevitably appear on the road surface due to various reasons, the attractiveness of the road surface is affected, the flatness is reduced, the cracks are extremely easy to absorb aggressive gases and moisture in the atmosphere and the water sprayed by rainwater, snow water or an artificial road surface, when the ambient temperature is lower than-5 ℃, the water in the cracks is expanded in volume, the width and depth of the cracks are enlarged, and the long-term road base layer, the subbase layer and even the roadbed are corroded by the water, so that the road surface collapse is caused, and the service life of the road is influenced. Therefore, when a crack occurs in the road surface, the crack of the road surface must be repaired in time. Early pavement cracks are narrower, the width of the crack is generally 1mm to 5mm, in order to ensure the repair quality of the crack, the crack is required to be grooved along the crack, the grooving width is 10mm to 30mm, and the grooving depth is 30mm to 50mm. The current popular technical method for repairing pavement cracks is as follows: firstly, a disc-shaped saw blade cutting machine is used for adjusting the saw blade to form a certain inclination angle with a road surface, two opposite directions are cut, two kerfs are formed into a V shape, then, the V shape is manually picked, chiseled and tidied to form a groove for construction, and then, a flexible material such as asphalt mastic or asphalt mortar is used for caulking and plugging the crack, so that the road surface base layer is isolated from moisture and gas in the atmosphere environment, and the road surface base layer is protected from being corroded by the moisture and the gas. If the slotting is not performed or the slotting depth is insufficient or the slotting cannot be performed accurately along the original cracks, the caulking material cannot fill the cracks fully and is embedded, and the caulking material is very easy to fall off from the cracks along with the running friction of a vehicle on a road surface, so that the meaning of repairing the cracks is lost. Accurate slotting of a reasonable groove for normal fracture is a key procedure for ensuring the quality of pavement repair.

The pavement crack grooving machine commonly used at present is a water-cooling disc blade type cutting machine.
In summary, the prior art has the following drawbacks: firstly, when the saw blade of the cutting machine is in a disc shape with the diameter more than or equal to 100mm and cuts into a pavement to a certain depth, if the cutting direction is changed, the two side surfaces of the cutter are subjected to the side force of the groove wall, so that the cutter cannot flexibly and smoothly slit along the bending crack direction, when the cutting direction is changed, smooth circular arcs corresponding to equal cutting radius cannot be formed, wavy folding lines are easy to form, V-shaped grooves cannot be formed, only slits, and secondly, the inclination angle of the cutting saw blade is adjusted, or one end of the cutting machine is manually lifted to incline the cutting machine, so that the cutting saw blade is inclined, the height is difficult to grasp, dynamic unbalance, large vibration and large noise are caused in the cutting process, mud splashes everywhere, the environment is polluted, the consistency of the formed V-shaped grooves is poor, the consistency is that the depth and the inclination angle are poor, a large amount of manual correction is required, the opposite direction is required to be repeatedly cut, the two slits are formed into a V shape, and then the grooves for construction are manually picked, the chisel and the arrangement are formed, and the working efficiency is low; thirdly, water is continuously sprayed in the construction process of the water-cooled grooving machine, water is accumulated in the grooves, and the joints cannot be embedded in time, so that the construction progress is affected; fourthly, the dust removing device adopts a dust collecting system and a dust falling system, so that the grooving machine mechanism is large, complex, heavy and consumes more energy; fifthly, the cutting blade is exposed outside the machine, and the cut crushed aggregates and flying dust are brought out by the cutting edge at a high speed to splash, so that the construction environment is bad, the environment is not protected, the people are easily injured, and the noise is high.
The working principle of the invention is as follows: under the drive of the power transmission mechanism, the groover rotates clockwise, the tip of the guide plate is aligned with the curve crack of the road surface, the hand wheel at the upper end of the screw is rotated, the upper frame deflects downwards around the right side of the cutter seat shaft at the left end, the cutter body cone end of the groover is driven to incline downwards, the dust collection device contacts with the ground to compress the dust collection spring to lift upwards along the guide sleeve direction, the blade starts to cut the road surface crack along with the descending of the groover, the hand wheel is rotated to adjust the grooving depth to meet the requirement, the handrail is held to drag the groover to advance along the curve direction of the crack, the cut road surface crack is in a V-shaped groove curved along the crack to a certain depth, the generated dust collides with the upper cover plate surrounding the upper end of the dust collection device of the groover and the dust collection cover at the side surface to fall into a dust collection cavity between the dust collection cover and the dust collection inner sleeve, settled dust is removed from the dust collection outlet at the lower part of the dust collection cover after a period of operation, the special grooving machine for repairing the road surface bending crack can continuously cut the V-shaped groove along the curve crack bending direction of the road surface.
Compared with the prior art, the invention has the following advantages.
1. The grooving machine cutter body adopts a cone shape, so that the grooving machine is not acted by lateral force of a groove wall when changing the advancing direction, thereby grooving can be accurately performed along the bending direction of the pavement crack, and the defect that the cutting direction of the disc cutter is not easy to change is avoided.
2. The conical cutter body is provided with a plurality of convex cutting edges on the outer surface, has good crushing performance, can finish cutting the V-shaped grooves with two neat sides along the bending direction of the pavement crack at one time, and avoids the defects of complex procedures of repeated cutting, manual picking, chiseling and finishing of the disc cutter. Labor is saved, and the working efficiency is greatly improved.
3. The conical grooving device is adopted, so that the friction area between the cutting tool and the groove wall is greatly reduced, the problem that water cooling is required due to overheating of the cutting tool is solved, the situation that a seam cannot be formed in time due to water accumulation in the groove is avoided, and the construction progress is improved.
4. The two dust collecting devices surround the conical groover, the bottom end is tightly attached to the ground, the materials cut by the groover slide out along the guide groove on the cutter body, dust naturally subsides in the dust collecting device, broken materials cannot fly out, and the dust collecting device has no energy consumption, is environment-friendly and does not hurt people.
5. The outward convex blades are spirally arranged, and the front blade angle is inclined towards the front lower side along the rotation direction of the grooving machine, so that the capability of the cutter body for drilling into the ground and cutting forward is enhanced, the cut pavement fragments and scraps are thrown out along the guide groove, and the set screw can accurately control the grooving depth.
