- the lifting cylinder 24 is an embodiment in which four lifting cylinders 24-a, 24-b, 24-c, and 24-d are installed in each of the support frames 23.
- four lifting cylinders 24-a, 24-b, 24-c, and 24-d are installed in each of the support frames 23.
- the lifting cylinder 24-a is first operated among the lifting cylinders installed by coupling to the four support frames 23 that are corners of the support unit 20.
- the hydraulic pressure is supplied from the hydraulic supply to the upper hydraulic hose 25, the cylinder rod 24a provided in the elevating cylinder 24-a is supported while being lowered to the working surface.
- a plurality of hydraulic lines 25a and 25b branched from the hydraulic hose 25 are connected to each lifting cylinder to provide hydraulic pressure.
- the hydraulic hose 25 is provided in plurality.
- the lifting cylinder 24 is driven to descend or ascend by driving a plurality of at the same time, the lifting cylinder is lowered at the time of lowering, when the pressure is applied to any one of the cylinders can not be lowered anymore, the other lifting cylinder continues Will descend.
- the plurality of lifting cylinders are all applied with a pressure greater than the supply hydraulic pressure, they cannot be lowered any more, and the plurality of lifting cylinders are in strong contact with the working surface.
- the branch point position branched from the hydraulic hose 25 to the hydraulic lines 25a and 25b is biased toward one of the lift points 24-a and 24-b rather than the center point.
- the long hydraulic line 25b from the branch point to the lifting cylinder has a built-in check valve (not shown), and the check valve is opened when the hydraulic pressure is higher than the pressure at which the cylinder descends.
- the hydraulic pressure is supplied to the other hydraulic line 25 b through the hydraulic check valve. In this way, if the remaining lifting cylinder 24-b descends and no longer descends in contact with the working surface, the hydraulic pressure is not supplied.
- the cylinders lowered by the hydraulic line branched from one hydraulic hose are not lowered equally, but one cylinder is lowered first and then completely lowered, and then the other cylinder is lowered, so that the operator of the cab can tilt the ground.
- Such lifting cylinders and ring gears have the advantage of being able to contact and support the drill bit easily and accurately in the desired direction and position even when the working surface is not inclined or flat.
- each corner part of the support part 20 can be stably supported on an uneven support surface.
- the hydraulic pressure is supplied to the lower side hydraulic line 25 to raise the cylinder rod 24a to the original position, and then rotate the support part 20 to the original position.
- the work is finished.
- the drilling operation using the drilling bit 62 may be performed while looking at the working environment on the monitor screen provided in the driver's seat through the camera 26 to further improve the convenience of the operation.
- the excavator-mounted core drill apparatus connects and installs a ring gear and a plurality of lift cylinders to a work support frame mounted at an end of an excavator work boom, thereby allowing the work support frame to rotate.
- the height of the inclined surface is adjusted by using the lifting cylinder to support the structure so that the drill bit provided in the work support frame is stable regardless of the inclination of the work surface to be drilled.
- the present invention is to install the camera on the work support frame in which the drilling bit is installed and to install the spray means to spray the water to the drilling work surface at the same time to check the work contents on the screen in the cab dust during the drilling work By making it possible to remove the work time and at the same time can be made environmentally friendly drilling.
