Description
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.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a marine structure, particularly maritime or landmark facilities, marine structures such as bridges and marine dolphin facilities, A core drilling apparatus suitable for perforating a rock in a construction site, the punching apparatus of the present invention can be fastened to a crane to improve mobility and compatibility, and can be used by being fastened to a small-sized crane. It is possible to work without receiving, and the angle adjusted to the left and right makes the drilling work easy by the mechanical characteristic of the fastening part. In the case of the hard rocky ground in the sea, the rotation speed is increased to speed up the drilling, Discharge is reduced, and thus stability from fine particle floats having vis- Can be easily adjusted by fastening the connecting rod part having different lengths according to the depth of the rock layer and it is possible to easily control the drilling depth, and the slime generated from the marine pollution can float, The present invention provides a core drill for joining a crankshaft, which can reduce the problem and perform a rotating rotation in which the perforation speed varies depending on the rock environment.

As described above, the technical idea of the present invention is that the
According to the present invention, there is provided a core drilling apparatus suitable for precisely perforating a rock with a diamond drill blade at a tip end thereof. The core drilling apparatus has a drilling depth It is easy to adjust, so it is not necessary to use a separate cylinder and chain for lifting and lowering. It is easy to adjust the drilling depth by replacing only the connecting rod part having different length. Hydraulic pressure is transmitted to the drill core device by fluid pressure through the inlet of the drill, so that it is drilled at the standard rotation speed in the ground. In the soft rock ground, it is rotated at a low speed and turbulent flow is formed. Diamond drill blades are precisely pierced without shaking. In hard rock, It is possible to control the piercing speed according to the depth or type of rock, and it has environmental protection to prevent the leakage of slime from the sea due to the stability and stability by adjusting the efficiency and the rotation speed desired by the driver. The present invention relates to a core drilling apparatus for joining a crankshaft, which is capable of rotating at a high speed while effectively raising the durability of the equipment by simultaneously reducing the frictional heat by the wet water injection from the triple water injection tip.
