[Industrial use]

The present invention relates to a circular cutting machine for road surface, and in particular, the distance between the center and the cutter itself is changed and operated even if the diameter of various manholes is changed by operating the compass type when the road traffic volume increases and the road is newly installed, repaired, or damaged. It relates to a road surface circular cutter to excavate the periphery of the lid support socket of the manhole to enable this.

[Private Technology]

In general, manholes buried in roads are installed to repair various facilities installed underground in KEPCO, Korea Telecom, waterworks, city gas, and road management offices.

However, when there is a sudden increase in traffic volume, road repair, or damage, repave the existing road with asphalt or concrete, and at this time, increase the height of the manholes installed therein by the thickness of the road paved to prevent traffic accidents and vehicle failures. You can do it.

Therefore, the impression of the manhole due to the resurfacing of the road should raise the height of the lid support socket for supporting the manhole cover. Therefore, the lid support socket must be excavated by excavating the surrounding road surface and concrete castings where the lid support socket is embedded. Excavation can be made between the lid support socket and the support wall so that the resurfaced road surface and the height of the manhole can be matched. For the conventional method, the EPO method is used.

The former conventional method is to excavate the road surface around which the lid support socket is buried to the extent that the lid support socket can be pulled out for the impression of the manhole. According to the cutter is installed with a circular saw blade that rotates the road while pushing the straight direction of the road cut into squares, the road surface and the concrete pour the surroundings so that the lid support socket is exposed.

However, in the conventional method as described above, since the operator has to rely on manual labor to cut the excavation site, not only a predetermined work time is required, but also the circular manhole and its shape are imbalanced as the excavation section is cut into a rectangular construction. There was a problem that the site was not beautiful.

On the other hand, the latter EPO method is a method of extracting the lid support socket by automatically cutting the excavated portion in a circular shape with a circular core cutting machine having a circumferential diameter equal to the size of the excavated portion when the peripheral portion of the lid support socket is excavated. Not only is it significantly shortened by about 2 to 3 hours than the conventional method, but since it is constructed in the same shape as the manhole after construction, there is an advantage that the construction site can be beautiful.

However, in the above EPO method, if the diameters of the various manholes are not the same and there is a difference, the circular core cutters must be changed at each time. Therefore, the circular core cutters of various sizes must be provided. Due to the many outgoing work is always due to the lifting of a separate crane has a problem that has a huge impact on the vehicle communication by the occupation of the road leading to the crane.

[Purpose of designation]

In order to solve the problems described above, the present invention is designed to solve the problems as described above, so that even if the diameter of various manholes is varied, the circular cutter is configured so as to be able to change and manipulate itself between the center and the cutter. The purchase cost of the cutting machine is significantly less than that of the EPO digging method, and as the cutting machine itself rotates, the excavation part is excavated, so that the work site can be kept clean.

Road surface circular cutting machine according to the present invention for achieving the above object can be smoothly rotated while supporting the rotating part in the center of the support plate and the circular support plate to support the entire weight at the same time is installed on the ground balance It is supported by the support portion protruding upwards so that the support portion and the support portion, and the center of gravity as the center of gravity, and the pivoting portion is installed in the rotational portion other than the rotational portion is rotated up and down to control each component It is characterized by consisting of a control box.

[Action]

Hereinafter will be described the operation of the present invention.

When the manhole is raised during the construction, repair, and damage of the road, a circular surface cutter is installed at the center of the manhole cover, the straight line of the excavation site around the manhole to be excavated, Manually adjusting the adjusting member 133 of the back and forth moving part 130 between the support plate 111 and the cutter member 153 installed on the manhole cover and the radius of the radius, the adjusting rack 132 engaged with the adjusting member 133 is moved forward and backward. After adjusting the radial distance corresponding to the diameter of the excavation site freely by the compass method, by operating the lifting bar 143 of the lifting unit 140 to position the cutter member 153 close to the road surface of the excavation site By operating the control box 160, the rotating part 120, the lifting part 140, and the excavating part 150 are operated by the signals of the control box 160, respectively.

That is, the excavation part 150 is driven by the driving motor 151 to rotate the cutter member 153, and the lifting unit 140 is gradually lowered so that the cutter member 153 can excavate the road surface. The road surface is rotated about the support 110 to move forward while digging in an arc direction.

For example, the cutter member 153 of the excavation portion 150 is composed of a main cutter 153a and an auxiliary cutter 153b to excavate the road surface, wherein the main cutter 153a can be naturally advanced in a straight direction. However, when digging in the circular arc direction (curve) alone, it cannot naturally move forward in the circular arc direction, and the main cutter 153a and the auxiliary cutter along the road surface with the auxiliary cutter 153b installed at a predetermined distance from the main cutter 153a. Excavation by an interval of 153b forms a space in which the main cutter 153a can be advanced in the arc direction.

Because the main cutter 153a is circular in front, but straight when viewed from the side view, when the road surface is excavated and inserted into the set depth, the excavated shape is straight, and when cutting it in a curved line, the cutting edge is advanced. And the excavation angle is not correct, the main cutter (153a) itself can not be smoothly advanced in the arc direction.

Therefore, the auxiliary cutter 153b is excavated at a predetermined interval from the main cutter 153a to form a space in which the cutting edge of the main cutter 153a inserted in the road surface can be smoothly rotated in the arc direction without interference. By simultaneously excavating the space to form a space by the excavation, the road surface is excavated and located between the main cutter (153a) and the auxiliary cutter (153b) the main cutter (153a) and the auxiliary cutter (153b) in the arc direction Since it is crushed while moving forward, the excavation around the manhole is easily excavated.

And, the lifting unit 140 serves to gradually lower so that the cutter member 153 of the excavation unit 150 can excavate the road surface to a predetermined depth, and once lowered by the set distance stops the lowering operation When the excavation part 150 excavates in an arc shape and returns to the original position, the elevating part 140 is elevated to its original position to return to its original position.

The rotating part 120 serves to be excavated in the arc direction when the road surface is excavated by the operation of the lifting unit 140 and the excavator, that is, the driving means 125 fixed to the support plate 111 is driven When the drive gear 126 is rotated, the rotating gear 124 meshed with the driving gear 126 is rotated, and the rotating plate 121 fixed and mounted integrally with the rotating gear 124 is also rotated at the same time. The excavation operation is performed by simultaneously rotating the front and rear moving parts 130, the lifting parts 140, and the excavator 150 integrally installed in the rotation direction in the rotation direction.

[effect]

As described above, the road surface circular cutter according to the present invention is operated by a compass type so that even if the diameter of various manholes varies, the circular cutter is configured so that the distance between the center and the cutter can be changed and manipulated by itself. Not only the purchase cost of the cutting machine is significantly lower than the excavation method, but also the excavation site is excavated as it is rotated by itself, which has the advantage that the manhole can quickly and accurately raise the work and keep the work site clean.
