[0002] Cast-in-place concrete surface is widely used in ground construction of highways, municipal projects, industrial plants and other projects. During the construction of concrete pavement, hard cutting is usually used for longitudinal and transverse joints. Hard cutting makes loud noise and generates dust. If the cutting time is not well controlled, burrs or uneven stress cracks will appear, which is neither economical nor environmentally friendly, and the construction quality cannot be guaranteed.

[0003] During the construction of cast-in-place concrete pavement, the construction of longitudinal and transverse joints is crucial to the construction quality of the surface layer. The construction method usually adopted for longitudinal and transverse joints is hard cutting with a hand-push cutting machine. During the whole process, there are several problems as follows: The hand-push cutting machine makes a lot of noise and easily generates dust. If the cutting time is not well controlled, burrs or uneven stress cracks will appear. The hand-push cutting machine requires a lot of manpower and material resources, which is not economical, not environmentally friendly, and cannot guarantee the construction quality.

[0004] Therefore, in view of the above problems, a rolling concrete pavement cutting device is proposed to solve the above problems. Utility Model Content

The support rod 1 and the mounting frame 2 are clamped by a connecting component 6, and the connecting component 6 and the mounting frame 2 are movably connected. The connecting component 6 can change its position on the mounting frame 2 to change the operating direction of the cutting during construction, so as to be able to cut seams of different directions or shapes, such as oblique seams or arc-shaped seams, thereby improving the practicability of the device.

[0030] In this embodiment, the connecting assembly 6 includes a connecting seat 61 and a connecting piece 62, and the connecting seat 61 is slidably arranged on the mounting frame 2. Specifically, a sliding groove is arranged on the mounting frame 2 along its length direction, and a slider is arranged on the connecting seat 61, and the slider is slidably connected to the sliding groove. Preferably, the slider and the sliding groove adopt a T-shaped connection to prevent the slider from falling off the sliding groove, and a positioning bolt is arranged on the slider, and the relative position of the slider on the mounting frame 2 is temporarily fixed by tightening the positioning bolt, so that the connection is more stable.

Further preferably, a tightening cover is threadedly arranged at one end of the support rod 1 close to the connecting piece 62, and the tightening cover can be screwed in by screwing in the thread of the tightening cover, so that the tightening cover can be close to the connecting piece 62 until the tightening cover contacts the outer wall of the card slot, so as to apply force to the outer wall of the card slot, so that the connecting piece 62 and the card slot are tightly fitted, thereby improving the stability of the device.

[0031] In another embodiment, the main body of the mounting frame 2 is configured to be semicircular, a sliding groove is configured along the circumference of the semicircle, and an angle scale can be configured on the outer side of the sliding groove with the center of the semicircle as the center to facilitate accurate adjustment of different angles of the connecting component 6, thereby improving the practicability of the device.

[0032] In this embodiment, the roller 3 includes a left roller 31 and a right roller 32, and the left roller 31 and the right roller 32 are both rotatably arranged on the mounting frame 2 through bearings, and the axes of the left roller 31 and the right roller 32 are in the same straight line. The left roller 31 and the right roller 32 are respectively arranged at two ends of the mounting frame 2, and a gap is set between the left roller 31 and the right roller 32. The gap is used to place the lifting frame 41 and the slice 5 on the lifting frame 41, and the axis of the slice 5 is in the same straight line with the axis of the roller 3 when the slice is cut, thereby improving the quality of the cutting construction.

[0033] In this embodiment, a transmission assembly 7 is also included, which is used to transmit and connect the slice 5 and the drum 3, so that the slice 5 and the drum 3 rotate together, and the cutting quality is better. The transmission assembly 7 includes a main gear 1 71, a slave gear 1 72, a slave gear 2 73, a main gear 2 74 and a telescopic shaft 75. The main gear 1 71 is coaxially arranged on the drum 3, and the main gear 1 71 and the slave gear 1 72 can be meshed and connected. The telescopic shaft 75 is arranged on the mounting frame 2. The telescopic shaft 75 can be a small electric push rod. The axis of the telescopic shaft 75 is parallel to the axis of the drum 3. A slave gear 1 72 and a slave gear 2 73 are coaxially arranged on the shaft 75 for rotation. The slave gear 1 72 is used to drive the slave gear 2 73 to rotate.

The main gear 2 74 is coaxially connected with the slice 5, and the main gear 2 74 and the slave gear 2 73 can be meshed and connected, thereby improving the stability of the device.

[0034] In this embodiment, the diameters of the main gear 1 71 and the main gear 2 74 are set to be consistent, the diameters of the slave gear 1 72 and the slave gear 2 73 are set to be consistent, and the diameters of the main gear 1 71, the main gear 2 74, the slave gear 1 72 and the slave gear 2 73 are all no larger than the diameter of the drum 3, so as to prevent the concrete from affecting the transmission assembly 7 in the working state, thereby improving the stability of the device, and the distance between the main gear 1 71 and the main gear 2 74 is set to be consistent with the distance between the slave gear 1 72 and the slave gear 2 73, so that they can mesh at the same time. At the same time, considering that the gear teeth may interfere with each other when the telescopic shaft 75 is retracted to make the gears mesh, during the retraction of the telescopic shaft 75, the support rod 1 can be slightly pushed and pulled to make the slice 5 and the drum 3 rotate slightly, driving the main gear 1 71 and the main gear 2 74 to rotate slightly so that the gears can be fully meshed, thereby improving the practicability of the device.

[0036] In another embodiment, the slice 5 is detachably arranged on the lifting frame 41, and the slice 5 includes a plurality of slices 5 with different diameters. The slices 5 with different diameters can be replaced according to construction requirements and concrete thickness, thereby improving the practicability of the device.

[0037] In this embodiment, a limit rod 8 is also included. The limit rod 8 is arranged on the mounting frame 2 and is used to locate the position of the lifting frame 41, so that when the lifting frame 41 contacts the limit rod 8, the axis of the slice 5 and the roller 3 are exactly in the same straight line, thereby improving the stability of the device. Preferably, the outer skin of the limit rod 8 is wrapped with a flexible material such as rubber to reduce the damage caused by the collision between the lifting frame 41 and the limit rod 8, thereby extending the service life of the device and improving the economy.

[0038] Working principle: according to the needs of the construction site, the support rod 1 is extended to a suitable length, the connecting assembly 6 is adjusted to a suitable position on the mounting frame 2, and the relative positions of the support rod 1 and the mounting frame 2 are temporarily fixed by positioning bolts and tightening covers, the device is placed on the surface of the concrete to be cut, the lifting power member 42 is started, the lifting frame 41 is rotated and lowered until the lifting frame 41 contacts the limit rod 8, the lifting power member 42 is paused, at this time, the axis of the slice 5 is in the same straight line as the axis of the roller 3, then the telescopic shaft 75 is retracted, and the roller 3 and the slice 5 are slightly rolled at the same time, so that the slave gear 1 72 and the main gear 1 71 are meshed with each other, and the slave gear 2 73 and the main gear 2 74 are meshed with each other; the support rod 1 is manually pushed or pulled to rotate the roller 3, thereby driving the slice 5 to rotate at the same time, so as to realize cutting on the concrete pavement, and the roller 3 is rotated. The cylinder 3 can level the concrete pavement on both sides of the slit while driving the slice 5 to slit, thereby improving the practicability of the device. After the slit is cut at one position, the telescopic shaft 75 is extended, so that the slave gear 72 is no longer meshed with the main gear 1 71, and the slave gear 2 73 is no longer meshed with the main gear 2 74, and then the lifting power member 42 is started again, so that the output end of the lifting power member 42 is retracted, driving the lifting frame 41 to rotate and rise, so as to drive the slice 5 to rise. After the slice 5 has no contact with the concrete pavement, the lifting power member 42 is suspended, and the construction personnel do not need to lift the device as a whole, and can use the rollers as walking wheels, and can drive the device as a whole to move on the concrete pavement by pulling the support rod 1, and after reaching the next slit position, the slice 5 is put down again for slit construction, thereby reducing labor intensity and improving construction efficiency.
