【考案の詳細な説明】
この考案は、岩盤に先端を当てて大衝撃力を加
え、岩盤の剛性値に打ち勝つた打撃力により岩盤
内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放射状に発生さ
せて岩盤を破砕する削岩のみに関するものであ
る。[Detailed explanation of the invention] This invention applies a large impact force by applying a large impact force to the tip, which overcomes the rigidity of the rock and drives it into the rock, causing plastic sliding failure at the tip and shearing. It only relates to rock drilling, which fractures rock by generating fracture cracks in a radial direction.
従来のモイルポイント形の削岩のみは、主幹と
なる大径の軸材と、ポイントホルダーに挿入した
上記軸材が抜け落ちないよう上記軸材の末端から
一体的に連なつて徐々に直径を太くしたテーパー
状の頭部とで構成されているので、削岩のみを同
一径にすることができない。 Conventional moil point-shaped rock drilling requires a main shaft with a large diameter, and the shaft inserted into the point holder is connected integrally from the end of the shaft and gradually increases in diameter to prevent it from falling out. Because it consists of a tapered head, it is not possible to make only the rock drilled the same diameter.
このような形状の削岩のみの頭部に大衝撃力を
加えて、軸材から岩盤に破砕衝撃を与えたとき、
反動で頭部に大きな衝撃が跳ね返つてくる。 When a large impact force is applied to the head of a rock drill with this shape, and a crushing impact is applied from the shaft material to the rock mass,
The recoil sends a huge impact back onto your head.
これを毎分60〜70回繰り返しているうちに歪力
が軸材と頭部との境界部分に集中するので、上記
境界部分が折損する欠点があつた。 As this process is repeated 60 to 70 times per minute, the strain force concentrates on the boundary between the shaft member and the head, resulting in the boundary breaking.
しかも上記の折損は、短期間に発生する。 Moreover, the above-mentioned breakage occurs in a short period of time.
この考案は、折損しないようにして、上述の欠
点を解消することを目的としている。 This invention aims to eliminate the above-mentioned drawbacks by preventing breakage.
この考案は、大径の軸材と、この軸材に大衝撃
力を加える頭部とを別々に形成し、ポイントホル
ダーに頭部と軸材の末端とを支持させるようにし
た削岩のみを提供する。 This idea consists of separately forming a large-diameter shaft member and a head that applies a large impact force to the shaft member, and allows only rock drilling in which the head and the end of the shaft member are supported by a point holder. provide.
以下、この考案の実施例を添付図面に基づいて
説明する。 Hereinafter, embodiments of this invention will be described based on the accompanying drawings.
図において、Ａは削岩のみで、この削岩のみＡ

から抜け落ちないテーパー部４を有する頭部５と
で構成されている。 In the diagram, A is only for rock drilling, and only this rock drilling is A.
has a tapered part 1 at the tip and a gentle taper part 2 at the end that will not fall off from the point holder.
It is composed of a large-diameter shaft member 3 having a large diameter shaft member 3, and a head portion 5 whose tip abuts against the end of the shaft member 3 and has a tapered portion 4 on the lower outer periphery that does not fall off from the point holder.
なお、図示のように軸材３の末端面中央部に突
面部６を設けておくことにより、この突面部６を
介し軸材３の軸芯に衝撃力を集中させることがで
きる。 By providing the protruding surface portion 6 at the center of the end surface of the shaft member 3 as shown in the figure, it is possible to concentrate the impact force on the axis of the shaft member 3 via the protruding surface portion 6.
この考案に係る削岩のみは、以上の構成であつ
て、第２図及び第３図で示したように外枠ハンマ
ーケースＢのポイントホルダーＣに軸材３、頭部
５を挿入する。 The rock drilling machine according to this invention has the above-described structure, and the shaft member 3 and head 5 are inserted into the point holder C of the outer hammer case B as shown in FIGS. 2 and 3.
このとき、ポイントホルダーＣの内周にテーパ
ー部２，４が接触して、上記ポイントホルダーＣ
から軸材３及び頭部５が抜け落ちるのを防止す
る。 At this time, the tapered parts 2 and 4 come into contact with the inner circumference of the point holder C, and the point holder C
To prevent the shaft member 3 and head 5 from falling off.
しかして、頭部５に間歇的に強力な衝撃力を加
えると、上記頭部５から軸材３をへて岩盤に破砕
衝撃を与えて、岩盤を破砕する。 When a strong impact force is applied intermittently to the head 5, a crushing impact is applied from the head 5 to the rock mass through the shaft member 3, thereby crushing the rock mass.
以上のように、この考案に係る削岩のみによれ
ば、先端に先細り部を、かつ末端にポイントホル
ダーから抜け落ちないテーパー部を有する大径の
軸材と、この軸材の末端に先端を突き合せると共
に、ポイントホルダーから抜け落ちないテーパー
部を有する頭部とで構成されているので、頭部に
大きな衝撃力を加えると、上記頭部から軸材をへ
て岩盤に破砕衝撃を与えることができる。 As described above, according to only the rock drilling method according to this invention, there is a large-diameter shaft member that has a tapered part at the tip and a tapered part at the end that does not fall out from the point holder, and the tip is inserted into the end of this shaft member. At the same time, the head part has a tapered part that does not fall out from the point holder, so if a large impact force is applied to the head part, a crushing impact can be applied to the rock through the shaft member from the head part. .
このため、従来のように軸材と頭部とが一体的
に形成されている削岩のみに発生した、軸材と頭
部との境界部分で歪の集中により折損するような
欠点を解消することができる。 This eliminates the problem of breakage due to concentration of strain at the boundary between the shaft and head, which occurs only in conventional rock drilling where the shaft and head are integrally formed. be able to.
