Abstract
A drill for drilling is disclosed. According to an embodiment of the present invention, there is provided a drilling drill comprising: a drill body having a guide hole formed in a lengthwise direction; a rod-shaped member coupled to the guide hole so as to be movable, A drill bit, and a driver for moving the drill bit to the outside of the drill body.
Description
The present invention relates to a drill for drilling.
In general, drilling is a process of drilling a hole with a small diameter in the earth crust to obtain structure and properties of the strata or to obtain oil, natural gas, hot spring water, ground water, and the like.
The drilling method includes an impact type in which the drill is impacted by crushing and drilling the rock in accordance with the excavation method, and a rotary type in which a drill bit made of a hard material is pressed against the rock surface to pierce the hole.
In the case of the rotary type, the stress is concentrated on the drill bit during the drilling operation, so that the bit is easily worn, the cutting force is decreased, and the replacement cycle of the bit is short, and there are many problems such as interruption of work and manpower consumption due to replacement of the bit.
A related art is Korean Patent Laid-Open No. 10-2010-0008587 (2010.01.26, drill bit for drilling).
Embodiments of the present invention are intended to provide a drill bit capable of continuously using a drill bit without increasing work time or replacement work even if the drill bit is worn by increasing the service life of the drill bit.
According to an aspect of the present invention, there is provided a drill body having a guide hole formed in a longitudinal direction thereof; A bar-shaped drill bit movably coupled along the inside of the guide hole and protruding from the drill body through the guide hole; And a driving portion for moving the drill bit to the outside of the drill body.
The drive unit may include a pneumatic or hydraulic actuator for pushing the drill bit outward from the guide hole.
The drive unit may include a compressor or a vacuum pump that varies the pressure of the space between the drill bit and the guide hole so that the drill bit is moved through the guide hole.
The drive unit may include a motor that rotates the drill bit about an imaginary axis parallel to the longitudinal direction of the drill bit.
The drilling drill may further include a helical guide portion formed in the drill bit and the guide hole, respectively, for guiding movement of the drill bit.
According to the embodiments of the present invention, the drill bit is protruded outward according to the degree of wear of the drill bit, so that even if the drill bit is worn, the drill bit can be continuously used without interruption or replacement work of the drill bit. It is possible to provide a drill for drilling that can drastically reduce the number of drill bit replacement operations compared to a conventional drill.
1 is a schematic view of a drill according to an embodiment of the present invention.
FIG. 2 is an enlarged view of a construction of a drill for drilling according to an embodiment of the present invention. FIG. 2 is a view showing an operation in which a bar-shaped drill bit moves along a guide hole of a drill body.
3 is a view schematically showing a drill according to another embodiment of the present invention.
FIG. 4 is an enlarged view of a construction of a drill for drilling according to another embodiment of the present invention, in which a rod-shaped drill bit moves along a guide hole of a drill body.
BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another.
In addition, the term " coupled " is used not only in the case of direct physical contact between the respective constituent elements in the contact relation between the constituent elements, but also means that other constituent elements are interposed between the constituent elements, Use them as a concept to cover each contact.
The terminology used in this application is used only to describe a specific embodiment and is not intended to limit the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the terms "comprises" or "having" and the like are used to specify that there is a feature, a number, a step, an operation, an element, a component or a combination thereof described in the specification, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the drilling drill according to the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like or corresponding elements, The description will be omitted.
The drill bit according to the embodiment of the present invention can be used for a long time without any work interruption or replacement work even if the drill bit is worn out during use because the drill bit is protruded according to the degree of wear of the drill bit Accordingly, it is possible to provide a drill for drilling which can reduce the number of drill bit replacement operations compared to conventional drill drills, thereby improving work efficiency and reducing cost.
