Description

TECHNICAL FIELD

[0001] The present application relates to a pavement construction equipment, in particular to a low-noise, low-pollution, high-efficiency and high-precision cement concrete pavement joint cutting equipment. BACKGROUND

[0002] In the construction process of cement concrete pavement surface layer slab, joint construction is an essential process. The joint can eliminate irregular cracks during the hardening period of construction, control the position of pavement slab disconnection, and also reduce the size of the concrete pavement plane and the temperature stress. According to the classification of the plane position, the joint is divided into longitudinal joint and transverse joint, and from the function, it is divided into construction joint, contraction joint and expansion joint. It should be noted that the construction joint and the contraction joint are the weakest parts of the entire pavement structure, so the construction precision and quality of the construction joint and the contraction joint are particularly important. The "Highway Cement Concrete Pavement Design Specification" stipulates the joint cutting depth, joint cutting width, joint spacing and slab division principle of longitudinal construction joint, longitudinal contraction joint, transverse construction joint and transverse contraction joint. The width of the construction joint and the contraction joint is generally 3-8mm, the joint cutting depth of the longitudinal construction joint is 30-40mm, the longitudinal contraction joint is 1 / 3-2 / 5 of the slab thickness, and the transverse construction joint and the transverse contraction joint are 1 / 5-1 / 4 of the slab thickness.

[0003] The concrete joint is currently mainly constructed by the traditional hand-push pavement joint cutting machine, which mainly has the following problems:

[0004] 1. The cutting depth of the concrete slab is mostly controlled by manually pressing the cutting machine downward, which is difficult to guarantee the experience and proficiency of the artificial, and the cutting depth of the same section often varies. In the case of shallow cutting, contraction joints will be generated at the adjacent contraction joints due to the lack of stress release, and in the case of deep cutting, the integrity of the pavement structure will be damaged.

[0005] 2. In the moving process of the existing hand-push pavement joint cutting device, the cutting machine is generally controlled to move forward by artificial along the line, and the cutting device cannot accurately keep straight cutting during the cutting process, which not only has a large working strength, but also is difficult to guarantee the cutting precision.

[0006] 3. In the existing cutting process, water is generally sprayed on the surface of the saw blade by artificial to cool it down, which not only causes uneven cooling and shortens the service life of the blade, but also forms mud slurry after the large amount of dust generated by cutting meets water, which flows to the concrete surface without organization and causes pavement pollution, and also has a bad influence on the paving of the upper structure layer.

[0007] 4. The existing hand-push pavement joint cutting machine generates a large amount of high-decibel noise during the construction process. Since the joint cutting usually needs to be completed at one time, the continuous high-decibel noise for a long time not only damages the health of the construction personnel, but also causes strong noise pollution to the surrounding environment, especially when it is constructed in the urban residential area, which has a greater influence on the life of the surrounding residents.

[0008] From the above, the traditional construction method and the existing equipment of the cement concrete pavement joint have the problems of low joint efficiency, high labor intensity, serious sewage and noise pollution, and difficult to guarantee the joint quality. SUMMARY

Based on the feedback from the locator, it controls the chassis to move along the designed cutting path. Within the designed cutting path, it controls the cutting device, cooling water device, and sewage collection device to perform cutting, cooling, and sewage collection tasks respectively. Based on the feedback from the tilt sensor, it controls the robotic arm to keep the tilt angle of the top plate adapted to the slope of the designed cutting path. Based on the feedback from the distance sensor, it controls the robotic arm to keep the distance between the top plate and the ground constant, so that the cutting depth of the cutting blade is always kept at the designed cutting depth. When the cooling water level sensor reports a lack of water, it triggers an alarm and controls the entire equipment to stop. When the sewage level sensor reports that the water level is close to full, it triggers an alarm and controls the entire equipment to stop.
