Description

Titanic rock drilling rig {TITANIC ROCK DRILLING APPARATUS}

The present invention relates to a titanic rock drilling apparatus.

In general, there are many examples of using a vibro hammer drill when excavating rocks at various construction sites. When excavating rocks with a vibro hammer drill, severe vibration and noise are induced, causing a lot of damage to people around the workplace. Not only that, but also the working speed is slowed down, and the working efficiency is lowered.

Accordingly, a method of drilling a hole of a certain size in the bedrock and then inserting a crusher into the hole to crack the rock was proposed, and the rock drilling device is a device used in such a rock excavation method.

The conventional rock drilling device connects the excavator to the fastening hole provided in the lower rear of both support plates, and then combines the drilling bit with the lower end of the rotary tube in a state where the support cylinder and the rotary tube are raised through the cylinder, the support cylinder and the rotary tube When the piston rod of the cylinder is lowered and the drilling bit is brought into contact with the surface of the rock, and then the hydraulic motor is operated to rotate the rotary tube and the drilling bit while gradually lowering the piston rod of the cylinder, a hole of a certain diameter can be drilled in the rock with the drilling bit.

However, in the conventional rock drilling apparatus as described above, a large pressure is applied to the drill bit during the operation of drilling the ground and the drill bit rotating at high speed is not stably supported, so that the drill bit and the bit rod vibrate excessively during drilling. However, there is a problem that not only causes a lot of civil complaints from residents around the construction, but also causes inconvenience to the workers due to severe noise.

In addition, since the drill bit is not stably supported and the vibration is severe, there is a problem that the operator cannot drill the desired position precisely.

In addition, since the conventional bedrock drilling apparatus is a method in which the ground is pulled out in a cylindrical shape after drilling, not only more noise is generated, but also there is a problem in that processing thereof is inconvenient.
