Description
本発明は、コンクリート等の硬質構造物へ孔を形成するのに用いられる穿孔装置に関する。
The present invention relates to a drilling device used for forming a hole in a hard structure such as concrete.
一般的にコンクリート構造物等へ大口径の孔を生成する場合、円筒形状のドリルを有したコアドリルを用いた穿孔工法を用いる。コアドリルを用いた穿孔工法では、先端に中空コアビットを取り付けたコアドリルを穿孔対象へ回転挿入し、円環状の溝に囲まれたコアを生成した後、コアドリルを引抜き、円環状の溝へタガネなどを打込むことでコアを根元から折り、穿孔対象と分離されたコアに輪を形成したワイヤーなどを引っ掛けた後、コアを取り出すことで孔を生成する。通常、コアドリルによる穿孔後のコア折り取りや取り出しは人力で行われているが、作業員の手作業による折り取りや取出し作業は手間がかかる。特に原子炉遮蔽壁に連続して穿孔して原子炉を解体する場合などは、コアが放射能に汚染されており作業員がコアに近づくことはできないため、コアの折り取り、およびコアの取出しを遠隔で行う手段の提供が望まれている。
Generally, when generating a large-diameter hole in a concrete structure or the like, a drilling method using a core drill having a cylindrical drill is used. In the drilling method using a core drill, a core drill with a hollow core bit attached to the tip is rotated and inserted into the drilling target. The core is folded from the base by driving, and a wire formed with a ring is hooked on the core separated from the object to be punched, and then a hole is generated by taking out the core. Usually, core break-up and removal after drilling with a core drill is carried out manually, but it is troublesome for a worker to manually break and remove the core. Especially when drilling continuously into the reactor shielding wall and dismantling the reactor, the core is contaminated with radioactivity and workers cannot approach the core, so the core can be folded and removed. It is desired to provide a means for remotely performing the above.
これに対し、コアの折り取り、および取り出しを自動化する技術の開発も行われている。コアドリルを用いた穿孔後のコア折り取り、コア取り出し装置として、特開２００７－１５４５４３号公報（特許文献１）には、先端部が環状をなして、内側に環状溝で囲まれるコアに係止する爪片を突設すると共に、後方に向かって漸次内側への突出量が増す突出部を設け、コア取出し治具を環状溝に強く押込むと、突出部がコアを径方向に押込み、該コアを根元より折って破断し、ついでコア取出し治具を引出すと、爪片で保持されたコアが抜き出されるようにしたコア取り出し治具が開示されている。
On the other hand, a technology for automating core folding and removal has also been developed. Japanese Laid-Open Patent Publication No. 2007-154543 (Patent Document 1) discloses a core breaker and core take-out device after drilling using a core drill. The tip portion is annular and is locked to a core surrounded by an annular groove inside. And a projecting portion that gradually increases inward toward the rear, and when the core removal jig is pushed firmly into the annular groove, the projecting portion pushes the core in the radial direction. A core removal jig is disclosed in which a core held by a claw piece is extracted when the core is folded and broken from the base and then the core removal jig is pulled out.
特許文献１のコア取出し治具は先端円環部の爪片の食込みでコアを保持しており、これを重力方向と同一方向の穿孔に用いた場合、爪片の摩擦力によってのみコアの保持を行うため、重量の大きいコアを取り出す際にコアが脱落するおそれがある。脱落を防ぐために係止部を大きくする場合、取り出し治具の挿入が困難になる欠点があった。また、コアの保持を先端円環部の爪片の食込みで行っており、コア取出し治具からのコア排出を容易に行うことができないため、取り出したコアの廃棄を穿孔装置単体で行うことが出来ないという欠点があった。
The core take-out jig of Patent Document 1 holds the core by biting the nail piece at the tip annular portion, and when this is used for drilling in the same direction as the gravity direction, the core is held only by the frictional force of the nail piece. Therefore, the core may fall off when taking out a heavy core. When enlarging the locking portion to prevent the dropout, there is a drawback that it is difficult to insert the take-out jig. In addition, since the core is held by biting the claw piece at the tip of the annular portion, it is not possible to easily discharge the core from the core removal jig. There was a drawback that it could not be done.
そこで、本発明は、コアドリルによる穿孔後に、コアドリル内で穿孔後のコアの把持を行い、かつ廃棄時にはコアの把持開放を行い、同一のコアドリルで容易にコアを抜き取ることができる穿孔装置の提供を目的とする。
Therefore, the present invention provides a drilling device that, after drilling with a core drill, grips the core after drilling in the core drill, releases the core at the time of disposal, and can easily extract the core with the same core drill. Objective.
このような課題を解決するために本発明の穿孔装置は、先端に中空ビットを備えた円筒形状のコアドリルと，コアドリルを穿孔対象に回転挿入する機構とを備えた穿孔装置において、前記コアドリル内にコアドリルの軸線方向に移動し、穿孔後のコアを把持するためのハウジングと，前記ハウジング先端に形成されたねじ部と，前記ねじ部と係合する、前記コアドリル内部に形成されたテーパ形状のテーパねじ部と，を備えたことを特徴とする穿孔装置である。
In order to solve such problems, a drilling device according to the present invention includes a cylindrical core drill having a hollow bit at the tip and a mechanism for rotating and inserting the core drill into a drilling target. A housing that moves in the axial direction of the core drill and grips the core after drilling, a screw portion formed at the front end of the housing, and a tapered taper formed inside the core drill that engages with the screw portion And a threading portion.
本発明によれば、コアドリルによる穿孔後に生成されるコアを、コアドリルを抜くことなく同じコアドリル内で把持し、かつ廃棄時にはコアの把持を解放することで、容易にコアを取り出すことができる穿孔装置を提供することができる。
According to the present invention, the core generated after drilling by the core drill is gripped in the same core drill without removing the core drill, and the core can be easily taken out by releasing the core at the time of disposal. Can be provided.

FIG. 5 is a cross-sectional view showing a method of breaking the core 201 using the core folding jig 106. After drilling to a predetermined position with the core bit 101, the protrusion 161 provided at the tip of the core folding jig 106 is inserted into an annular groove formed around the core 201. When force is further applied downward after insertion and the protrusion 161 is pushed in, a lateral force is applied to the upper portion of the core 201.

Due to the rotation of the housing 104 and the inclination of the taper screw portion 151, the core 201 is clamped in the core drill 100 by being fastened to the housing 104 with a strong force. Further, by extracting the core drill 100 while maintaining the state in which the core 201 is held, the core 201 can be transported from the hole in which the core 201 is drilled. Furthermore, when the housing 104 is rotated in the direction opposite to that when the housing 104 is tightened, the front end of the housing 104 is weakened and the core 201 can be released. Even when a force generated in the direction of gravity is applied to the core generated after being drilled by the core drill, the core can be easily taken out by releasing the grip of the core at the time of disposal.
次に図７を用いて、貫通孔を生成する際にコアの把持を維持した状態で穿孔を行うことで、コアの落下を防ぐ穿孔方法を説明する。
Next, referring to FIG. 7, a drilling method for preventing the core from falling by drilling while maintaining the gripping of the core when generating the through hole will be described.
図７はコアの把持を維持した状態で穿孔を行う方法を示す断面図である。
FIG. 7 is a cross-sectional view showing a method of drilling while maintaining the core gripping.
ここで、図７は穿孔装置１により、下面まで達するような部材を穿孔対象２００として説明する。
Here, in FIG. 7, a member that reaches the lower surface by the punching device 1 will be described as a drilling target 200.
図７（ａ）に示すように所定の深さまで穿孔し、コアビット１０１をわずかに引き上げた後、図６で示した方法と同様にハウジング１０４と環状把持具１０５によりコア２０１を把持する。次にハウジング１０４の位置を保持した状態で、コアビット１０１を下降すると、環状把持具１０５とコアビット１０１は分離し、コア２０１を把持した状態でコアビット１０１を回転できるようになる。この状態でコアビット１０１を下方へ回転駆動することにより、図７（ｂ）に示すようにコア２０１の把持状態を維持しながら、コアビット１０１を貫通させることができる。コア２０１はコアドリル１００内に把持されているので、脱落させること無く貫通孔を生成することができる。
As shown in FIG. 7A, after drilling to a predetermined depth and slightly raising the core bit 101, the core 201 is gripped by the housing 104 and the annular gripper 105 in the same manner as shown in FIG. Next, when the core bit 101 is lowered while the position of the housing 104 is maintained, the annular gripper 105 and the core bit 101 are separated, and the core bit 101 can be rotated while the core 201 is gripped. By rotating the core bit 101 downward in this state, the core bit 101 can be penetrated while maintaining the gripping state of the core 201 as shown in FIG. Since the core 201 is held in the core drill 100, a through hole can be generated without dropping.
次に図８を用いて、穿孔後のコアの把持だけでなく、確実にコアを下部で破断するためにコアの下部に切り溝を形成する方法を説明する。
Next, with reference to FIG. 8, a method for forming a kerf in the lower part of the core to surely break the core at the lower part as well as gripping the core after drilling will be described.
図８はコアへ切り溝を形成する方法を示す断面図である。
FIG. 8 is a cross-sectional view showing a method of forming a cut groove in the core.
切り刃１４２が先端に備えられたハウジング１０４を用いて図６に示した把持方法を実施すると、切り刃１４２の先端がコア２０１と接する。その後さらにハウジング１０４、またはコアビット１０１を回転駆動すると図８（ａ）に示すように切り刃１４２がコア２０１に食い込みながら回転し、コア２０１に切り溝２０２が形成される。その後、図８（ｂ）に示すようにハウジング１０４を反対方向に回転することでコア２０１を開放し、コア２０１へ切り溝２０２が形成された状態でコア折り治具１０６の突出部１６１を挿入することによりコア２０１の上部へ横力を加えると、形成した切り溝２０２へ応力集中が発生し、コア２０１は切り溝２０２に沿って破断される。これによりコア２０１が途中で折損することなくコア２０１の下部で確実に折り取ることができる。
When the holding method shown in FIG. 6 is performed using the housing 104 provided with the cutting edge 142 at the tip, the tip of the cutting edge 142 contacts the core 201. Thereafter, when the housing 104 or the core bit 101 is further rotationally driven, the cutting blade 142 rotates while biting into the core 201 as shown in FIG. 8A, and a cut groove 202 is formed in the core 201. Thereafter, as shown in FIG. 8B, the core 201 is opened by rotating the housing 104 in the opposite direction, and the protruding portion 161 of the core folding jig 106 is inserted in a state where the groove 202 is formed in the core 201. Thus, when a lateral force is applied to the upper portion of the core 201, stress concentration occurs in the formed kerf 202, and the core 201 is broken along the kerf 202. As a result, the core 201 can be reliably folded at the lower portion of the core 201 without breaking in the middle.
なお、本発明は上記した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、図１に示したコアドリル１００で、貫通孔を生成する必要がない場合はコアビット１０１と環状把持具１０５は一体となっているツールに置き換えることが可能であり、必要とする機能に応じて構成を変更することも可能なことは明らかである。また、穿孔対象の厚さやコアの把持を行う位置に応じてコアチューブ１０２等を交換することにより、コアドリル１００の長さを容易に変更することができるので、コアドリル１００内で装置同士が干渉することなく穿孔が可能である。
In addition, this invention is not limited to the above-mentioned Example, Various modifications are included. For example, in the core drill 100 shown in FIG. 1, when it is not necessary to generate a through-hole, the core bit 101 and the annular gripper 105 can be replaced with an integrated tool, depending on the function required. It is clear that the configuration can be changed. Moreover, since the length of the core drill 100 can be easily changed by exchanging the core tube 102 or the like according to the thickness of the drilling target or the position where the core is gripped, the apparatuses interfere with each other in the core drill 100. Drilling is possible without any problems.
コアドリル１００の駆動機構の構成は図４に示した構成に限定されるものではなく、本発明に必要な動作を実現することができる他の構成であれば良く、例えばハウジングの上下方向やコア折り治具の駆動はシリンダを用いても良い。
The configuration of the drive mechanism of the core drill 100 is not limited to the configuration shown in FIG. 4 and may be any other configuration that can realize the operations necessary for the present invention. A cylinder may be used to drive the jig.
図９は本発明にかかる穿孔装置の実施例２で、穿孔装置を移動し任意の位置へ穿孔するための構成を示している。駆動機構部２を上下に移動するためのガイドバー３は上部を移動機構２１に設置されており、下部にはガイドバー３の振れ防止用の固定治具２２を備えている。移動機構２１は天井に設置されたガイドレール２３に設置され、ガイドレール２３に沿って移動することができる。これより、コアドリル１００内で折り取ったコア２０１を把持した状態で穿孔装置１を所定の位置へ移動することで、コア２０１を所定の位置へ運搬し廃棄することが無人で行うことが可能になる。なお、穿孔装置１は制御機構２４を有しており、これにより遠隔操作が可能となる。また、図９に示す任意の位置へ移動する構成は、ガイドレールを用いた移動に限定されるものではなく、ロボットマニピュレータを用いた移動など、他の移動手段を用いることも可能なことは明らかである。このように穿孔装置１の設置方法は図３の構成に限定されるものではなく、様々な形態をとることができる。
FIG. 9 is a second embodiment of the punching apparatus according to the present invention, and shows a configuration for moving the punching apparatus and drilling to an arbitrary position. A guide bar 3 for moving the drive mechanism unit 2 up and down is provided with a moving mechanism 21 at the top and a fixing jig 22 for preventing the guide bar 3 from shaking. The moving mechanism 21 is installed on a guide rail 23 installed on the ceiling, and can move along the guide rail 23. Thus, by moving the drilling device 1 to a predetermined position while holding the core 201 broken in the core drill 100, the core 201 can be transported to the predetermined position and discarded unattended. Become. The punching device 1 has a control mechanism 24, which enables remote operation. Further, the configuration for moving to an arbitrary position shown in FIG. 9 is not limited to the movement using the guide rail, and it is obvious that other movement means such as movement using a robot manipulator can be used. It is. Thus, the installation method of the perforation apparatus 1 is not limited to the structure of FIG. 3, and can take various forms.
