Abstract

The present invention relates to a core drill to be combined with an excavator, capable of floating rotation, and more specifically, to a core drill device combined with an excavator proper to punch bedrock for the construction of an offshore structure especially such as a light beacon facility offshore or on the land, bridge, and dolphin facility. The core drill is proper to precisely punch bedrock with a diamond drill blade on the front end, and can easily control the punching depth with a fastening rod unit with different lengths in accordance with the depth of bedrock offshore, without needing an elevating/lowering device using a separate cylinder and a chain. It is easy to control the punching depth by replacing only the fastening rod unit. The core drill conveys the oil pressure to a drill core device fluidly through an oil pressure input hole with different usages. The core drill punches a hole at a standard rotation speed on general bedrock, precisely punches a hole on soft bedrock by rotating at a low speed and preventing slime from being discharged, and rapidly punches a hole on hard bedrock by rotating at a high speed. The core drill has efficiency and stability, and prevents environmental pollution by preventing offshore slime from leaking. The core drill effectively reduces frictional heat by wet water spray from a triple water spray tip on the land to simultaneously increase durability of the equipment and work efficiency. The angle of the excavator is controlled forward and backward with a rotating plate. The core drill can make a floating rotation where the punching and rotating speed changes in accordance with the depth or material of the bedrock.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a core drill for a fork-

Field of the Invention [0001] The present invention relates to a core drill for joining a crane capable of rotating in a fluidized manner, and more particularly to a core drill for joining a crane for a crane for joining a marine structure such as a marine structure, The core drilling device is suitable for drilling the core drill, and it is possible to tighten the fastening rod portions having different lengths according to the depth of the rock bed, thereby facilitating the depth adjustment and transferring the hydraulic pressure fluidly through the hydraulic inlet for different purposes to the flow rotating portion and the core drill portion, In the ground, it is drilled at the standard rotation speed. In the rocky ground, it rotates at a low speed. In the rocky ground, the rock is punctured by high speed rotation. The present invention relates to a core drilling apparatus for joining a crankshaft.

Generally, in the sea, a work is carried out by installing a casing together with a hypothetical jacket made of a steel pipe at the time of drilling the rock layer. Particularly, excavation of rock layers from the land causes severe vibration and noise. Therefore, cracks are generated in the buildings around the work site during drilling in the urban area, and the work is frequently interrupted due to noise complaints And the construction of the above method is gradually diminishing in the domestic including the advanced countries.

As a method for solving the above problems, a dry core drill to prevent dust scattering and a cylindrical cutter blade punching apparatus with excellent working efficiency have been used and are used. Although this is faster than the above-described conventional methods, And it is not easy to fasten to a moving means such as a crane and the rotating speed is fixed and the rotating blade may be damaged or overload due to frictional heat may be applied to the core drilling device.

In addition, in the rocky ground of the sea, if the rotation speed is increased and the bit portion is provided at the end to hit the drilling operation speed, the drilling operation speed is considerably quick. However, the rock core in the shape of a cylinder is broken into a plurality of pieces, It takes a long time to work and the work productivity is deteriorated when the operation of removing the rock core which is deeply broken is taken into consideration.

In contrast, the depth and type of the rock bed are different from those of the rocky soils on the oceanic soft rock soils. In the case of bit strikes using the hammer in the soft rock soils, There is a problem in that the operation is delayed if there is an environmental pollution problem in which floating matter occurs on the sea surface and if there is enough water to be able to form slime in the sea bed layer.

Recently, as disclosed in Japanese Patent Application Laid-Open Nos. 10-2011-0084651 l and 10-1508740, a core tube is composed of a cylinder type or a chain, and a device for raising and lowering the core tube and a drill for a core barrel operation As shown in the prior art below.
