Description
【考案の詳細な説明】 (1) 産業上の利用分野 この考案は、削岩のみに関するものである。[Detailed explanation of the idea] (1) Industrial application field This invention relates only to rock drilling.
(2) 従来の技術
コンクリートや鉄筋コンクリート壁及び柱に削
岩のみを当てて大衝撃力を加え、コンクリートや
鉄筋コンクリートの剛性値に打ち勝つた打撃力に
より上記壁や柱に打ち込んで先端部に塑性すべり
破壊を起させると共に、剪断破壊による亀裂を発
生させてコンクリートや鉄筋コンクリート壁及び
柱を破壊、切断していた。(2) Conventional technology A large impact force is applied by only drilling rock to concrete or reinforced concrete walls and columns, and the impact force that overcomes the rigidity of the concrete or reinforced concrete is used to drive the rock into the walls or columns, resulting in plastic slip failure at the tip. In addition to causing cracks due to shear failure, concrete and reinforced concrete walls and columns were destroyed and cut.
(3) 考案が解決しようとする問題点
削岩のみは、モイルポイント形のため、刃先が
面積の小さい尖鋭状となり、面積の大きい破壊に
よる亀裂を発生させることができない問題があつ
た。(3) Problems to be solved by the invention Since the rock drilling tool has a moil point shape, the cutting edge has a small area and is sharp, making it impossible to generate cracks due to large area fractures.
また、破壊面に対するすべり止めがないため、
横すべりが発生し、有効に破壊及び切断すること
ができない問題もあつた。 In addition, since there is no anti-slip against the fracture surface,
There was also the problem that sideways sliding occurred, making it impossible to effectively destroy and cut.

A base plate having anti-slip protrusions projecting forward on both sides of the tip edge, a cutting edge provided between the tip edge protrusions of this base plate, and a tip end portion of a shaft member with a flat tip surface at the center of the distal edge of the base plate. A cylindrical portion provided to fit the
This structure consists only of rock drilling with the support wire engagement member provided on the substrate.

である。(5) Function This invention involves inserting the head end of the shaft into the point holder of the lock breaker, supporting the base plate on the lock breaker with a wire inserted through the lock breaker and the engaging member, and then moving the shaft into place. The cutting edge is designed to destroy and cut concrete, reinforced concrete walls, and columns while intermittently applying a strong impact force to the board, and the protruding pieces prevent the cutting edge from coming off the destroyed surface. .
(6) 実施例
図において、Ａは削岩のみで、この削岩のみＡ
は、先端縁の両側に前方に突出するすべり止め用
の突片１，１′を有する基板２と、この基板２の
先端縁上記突片１，１′間に設けた刃先３と、上

６とで構成されている。(6) Example In the figure, A is only for rock drilling, and only this rock drilling is A.
consists of a substrate 2 having anti-slip protrusions 1 and 1' protruding forward on both sides of the tip edge, a cutting edge 3 provided between the protrusions 1 and 1' on the tip edge of this substrate 2, and the substrate 2. The cylindrical part 5 protrudes from the center of the end edge of the shaft member 2 and is provided to fit the front end of the shaft member 4 if the front end surface is flat, and a support wire engagement member 6 provided on the base plate.
上記の筒部５は、図示の場合筒部５から突出す
る二叉片７を設けると共に、この二叉片７間に基
板２の末端縁に設けてある切欠き部８を嵌め込
み、そして溶接により基板２に二叉片７を固着し
た。 In the illustrated case, the cylindrical portion 5 is provided with two prongs 7 projecting from the cylindrical portion 5, and a notch 8 provided at the end edge of the substrate 2 is fitted between the two prongs 7, and then welded. The two-pronged piece 7 was fixed to the substrate 2.
また係合部材６は、図示の場合基板２の末端縁
両側に透孔９を設け、そしてこの透孔９にシヤツ
クルを取付けた。 In addition, in the illustrated case, the engaging member 6 has a through hole 9 provided on both sides of the end edge of the substrate 2, and a shackle is attached to the through hole 9.
この考案に係る削岩のみは、以上の構成であつ
て、次に使用方法を説明すると、第２図で示した
ようにロツクブレーカーＢのポイントホルダーＣ
に軸材４の頭端を挿入すると共に、ロツクブレー
カーＢと係合部材６とにワイヤー１０を挿通し
て、上記ロツクブレーカーＢに削岩のみＡを支持
させる。 Only the rock drilling machine according to this invention has the above-mentioned configuration.Next, to explain how to use it, as shown in Fig. 2, the point holder C of the rock breaker B is
The head end of the shaft member 4 is inserted into the rock breaker B, and the wire 10 is passed through the lock breaker B and the engaging member 6, so that the rock breaker B supports only the rock drilling A.
しかして、軸材４に間歇的に強力な衝撃力を加
えると、上記軸材４から基板２をへて刃先３によ
りコンクリート或は鉄筋コンクリート壁及び柱Ｄ
に破砕衝撃を与えて、壁或は柱Ｄを破砕する。 When a strong impact force is applied intermittently to the shaft member 4, the cutting edge 3 passes from the shaft member 4 through the base plate 2, causing concrete or reinforced concrete walls and pillars D.
A crushing impact is applied to the wall or column D to crush it.
以上のように、この考案に係る削岩のみによれ
ば、基板の先端縁に刃先を形成してあるので、刃
先の面積が大となる。 As described above, according to only the rock drilling method according to this invention, since the cutting edge is formed at the leading edge of the substrate, the area of the cutting edge becomes large.
このため、モイルポイント形と異なつて面積の
大きい破壊による亀裂を確実に発生させ、有効に
破壊、切断することができる。 Therefore, unlike the moil point type, it is possible to reliably generate cracks due to destruction with a large area, and to effectively destroy and cut.
また、基板の先端縁両側にすべり止めの突片を
設けてあるので、破壊時における削岩のみの横す
べりを防止することができる。 In addition, since anti-slip protrusions are provided on both sides of the tip edge of the substrate, it is possible to prevent only rock drilling from sliding laterally during fracture.
