The present invention relates to a core drill, and more particularly, to a device for controlling a core drill.
In general, there are many examples of using a vibro-hammer drill or the like when excavating a rock at various construction sites. When the rock is excavated with the vibro-hammer drill, severe vibration and noise are incurred, which causes great damage to people around a workplace and slows down a work speed, so that work efficiency is reduced.
Accordingly, a construction method of boring a hole having a predetermined size in a rock and inserting a crusher into the hole to crack the rock was proposed. The present invention particularly relates to a rock drilling apparatus used in such a rock excavation construction method.
According to the related art, the rock drilling apparatus has been proposed as published in Korean Unexamined Utility Model Publication No. 1996-5390 that discloses an apparatus, in which a base plate and an upper plate are installed at lower ends and upper ends of a pair of support plates, respectively, the support plate being formed on a lower rear side thereof with a fastening hole for connecting an excavator; a pair of guide posts are installed between the base plate and the upper plate; a hydraulic motor is installed on an upper portion of a support cylinder, which is installed on the guide posts so as to be freely lifted and lowered, while the hydraulic motor is connected to a rotation tube installed on a lower portion of the support cylinder; and a cylinder connected to the support cylinder is installed on an upper portion of the upper plate.
According to the rock drilling apparatus of the related art, an excavator is connected to the fastening hole formed on the lower rear side of each of both support plates, a drill bit is coupled to a lower end of the rotation tube while the support cylinder and the rotation tube are lifted through the cylinder, the support cylinder and the rotation tube are lowered to allow the drill bit to make contact with a surface of the rock, and the hydraulic motor is operated to gradually lower a piston rod of the cylinder while rotating the rotation tube and the drill bit, so that a hole having a predetermined diameter may be drilled in the rock with the drill bit. However, according to the rock drilling apparatus of the relate art as described above, the cylinder is installed on the upper portion of the upper plate so as to be exposed, so that an appearance may deteriorate, there are many concerns that the cylinder may be damaged by an external impact, and an overall length may become longer, and thus production and handling may become very inconvenient.
In addition, the excavator is coupled to the lower rear side of the support plate so that work stability may be greatly reduced, and the apparatus has to be placed to stand vertically when attached to and detached from the excavator, transferred, or stored so that there are many concerns of damage caused by unnecessary contact or impacts to the cylinder exposed to an outside and each component including the hydraulic motor, and there are many concerns that the apparatus may be overturned by an external impact so as to be seriously damaged.
In order to overcome the above problems, Korean Utility Model Registration No. 20-0361015 entitled “Rock Drilling Apparatus” has been proposed. According to the rock drilling apparatus of the related art, the rock drilling apparatus has a compact configuration with a smaller size so that the production and handling may be simplified, the rock drilling apparatus may be horizontally laid so as to be attached and detached, transferred, and stored more safely, each constituent component may be prevented from being damaged by an external impact, and reduction of an overall vertical length or deepening of a drilling depth may be performed.
Conventionally, as a device for controlling each component of a core drill, which is the rock drilling apparatus, there is a device for manually operating a plurality of levers. However, since the device is a manual type, it is inconvenient to use the device. As disadvantages of using a conventional core drill, there are increases in a construction cost and a construction period, which increase a construction expense during a rock crushing work. In addition, an existing use scheme is a manual operation scheme, which currently incurs an expensive labor cost, and a worker performs an unsafe work by a work scheme with extreme labor in a blind spot where safety of the worker is vulnerable at inadequate construction sites.
