Based on the main frame and the hydraulically rotating support table.
The drilling rig is used for drilling holes in bottoms and concrete tanks up to DN 3000mm (external Ø 3300mm), H-2650mm high and weighing up to 12,000 kg.
Taking into account the specific guidelines, this machine cannot be used for other tasks than it is intended for. It is based on the main frame and a hydraulically rotating table. Equipped with GRP side curtains against splashing of spoil.
The operator has a control panel with PLC control at his disposal, equipped with a fully touch HMI panel with a dialog window in which all technological parameters are given.
The maximum diameter of a drilled hole with the use of a suitable crown is Ø1200, while the smallest hole / crown is Ø150. The drilling rig is equipped with a hydraulic unit with gradual adjustment of the drill speed, from 0 rpm. up to max. 400 rpm
After the product is positioned on the turntable and the drilling rig is zeroed, the operator coordinates the well inlet coordinate, the drilling rig will automatically adjust the height on the mast. The drilling is performed by the operator by selecting the appropriate rotation and clamping force using potentiometers. After drilling the borehole, the operator enters the coordinates of the outlet No. 1, the angle of the table, the height of the outlet is set automatically, in the drilling mode, the operator selects the rotation and clamping force manually. After drilling the borehole, the operator enters the coordinate of the outlet No. 2, the angle of the table, the height of the outlet is set automatically, in the drilling mode, the operator selects the rotation and clamping force manually. In order to maintain the service life, cooling water is constantly supplied to the drilling site. The operator can move the column by a value of +/- 500mm from the axis, the shift takes place through a trapezoidal screw equipped with an encoder for precise positioning.

Technical specifications:
– Maximum load capacity 7.000 kg
– Maximum product height 2000-2500 mm
– Hydraulic unit, 150 liter tank with filter and cooler, gear pump 120 bar. and a 250 bar piston pump. Proportional control
– GRP side covers. For splash protection
– Maximum diameter of the drilled hole fi 1000
– Maximum drill speed 400o / min.
– 1 1/4 “drill bit clamping
– PLC control, HMI touch display (angle settings, drill height in automatic mode)
– Cooling water supply via a solenoid valve
– Laser reading of the drill position
– Smooth regulation of drill revolutions 0-400 o / min
– Smooth adjustment of the pressure of the drill
– Reading the pressure on the pressure gauges

Job description:

After setting the product on the turntable and zeroing the drilling rig, we enter the coordinate of the well outlet, the drilling rig will automatically adjust the height on the mast, the drilling is performed by the operator by selecting the appropriate rotations, clamping force, using potentiometers.

After drilling the bore, the operator enters the coordinate of inlet no. 1, then gives the angle of the table, the height of the outlet is set automatically, in the drilling mode, the operator selects the speed and pressure manually.

After drilling the first hole, the operator enters the coordinate of inlet no. 2, then gives the angle of the table, the height of the outlet is set automatically, in the drilling mode, the operator selects the speed and pressure manually.

The activities are repetitive.
