& Highway construction HZ type trailer type drilling core machine horsepower Honda electric start concrete core machine
Concrete drilling core machine manufacturer drilling core machine price HZ type concrete drilling machine special for road drilling The core drilling machine is mainly used for drilling and coring hardened concrete in buildings, highways, airports, docks, dams, etc. It has the characteristics of simple operation, convenient movement of the machine, accurate drilling and coring, smooth surface of the core sample, and good accuracy of the core sample. It is an indispensable equipment for highway transportation departments, construction departments and related colleges and universities to prevent accidental damage. This machine complies with the standard B "Technical Requirements for Concrete Drilling and Coring Machines".
In addition, this drilling rig can also drill and core other non-metallic brittle and hard materials, such as refractory materials, ceramics, glass, and rocks.

3. Structural Principle
This machine mainly consists of the following parts (as shown in the figure)
Frame: its column is equipped with a rack, and its base is equipped with four adjusting screws.
. Sliding seat: It is set on the column. The internal gear and the rack on the column form a gear pair. Turn the feed handle to make the sliding seat move up and down along the column.
Gear box: It is fixed on the sliding seat, and its spindle is equipped with a drill bit, which feeds along with the sliding seat to achieve the purpose of drilling.
4. How to use
Move the machine to the place where cores need to be drilled, screw on four adjusting screws on the base, adjust the level of the machine, and embed iron expansion bolts on the ground. to secure the unit.
. Install the drill bit according to the drilling size requirements.
Connect the water source and check whether there is water leaking out of the drill bit.
Turn on the power switch, idle for a few minutes, and turn the feed handle to drill.
5. Precautions
When drilling, the feed speed should be ensured to be uniform, about ~/. If the drill bit is found to be stuck, the feed speed can be appropriately reduced, and the drill bit can be raised by a certain amount if necessary. , and then drill in slowly. Avoid drilling hard to avoid damaging the drill bit and the machine.
. Sufficient water cooling must be maintained throughout the drilling process.
When drilling is completed, the machine can only be stopped when the drill bit is separated from the workpiece.
During the drilling process, overloading is not allowed. When the motor temperature exceeds ℃ (it feels hot to the touch), the loading force should be reduced and a new drill bit should be replaced.
6. Maintenance and Inspection
Regularly check the joints of each component. If there is any looseness, adjust it in time.
When installing the drill bit, calcium-based grease should be added to the two threads.
After drilling, clean all parts of the drilling rig and add lubricating oil to the column and rack.
Replace the grease in the reducer every six months.
