【発明の詳細な説明】
本発明はモーター又はエンジンで回転する動カバンマー
に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable van mer that is rotated by a motor or engine.
本発明は、確実に作動する動カバンマーにつき工夫した
ものである。The present invention has been devised to provide a movable bag mer that operates reliably.
従来の動カバンマーは、小型の場合は比較的安定して作
用するが、大型の場合は、時々動かなくなることがあっ
た。その原因と現象につき説明すると、第1図および第
4図は従来例であり、(1)は摺動筒、(2)は摺動筒
(11の先端に取付けられている杭等の工具で、該工具
(2)の後端(3)は、摺動筒(11の先端の内側に少
しばかり突き出ている。(4)は摺動筒(1)内に嵌合
したハンマ一体であり、後端(5)は開口している筒形
に形成され、内部にはピストン(6)が嵌合している。Conventional movable kabummers work relatively stably when they are small, but when they are large they sometimes get stuck. To explain the causes and phenomena, Figures 1 and 4 show conventional examples, (1) is a sliding tube, and (2) is a tool such as a pile attached to the tip of the sliding tube (11). , the rear end (3) of the tool (2) protrudes a little inside the tip of the sliding tube (11). (4) is an integrated hammer fitted into the sliding tube (1), The rear end (5) is formed into an open cylindrical shape, and a piston (6) is fitted inside.
(7)はピストンロンド、(8)はクランクである。即
ち、クランク(8)が半回転するとピストン(6)は第
4図で後退するが、該ピストン(6)は前記ハンマ一体
(4)の内部にキラチリ嵌っているので、ピストン(6
)の頭部の密閉室OI内には空気は入らないので、ハン
マ一体(4)もピストン(6)と共に後退し、クランク
(8)が更に半回転すると、ピストン(6)が前進する
とき、ハンマ一体(4)も前進させて、その先端で工具
(2)の後端(3)を叩いてハンマーとするのである。(7) is a piston rond, and (8) is a crank. That is, when the crank (8) rotates half a turn, the piston (6) moves backward as shown in FIG.
) Since no air enters the sealed chamber OI at the head of the hammer (4), the hammer unit (4) also moves back together with the piston (6), and when the crank (8) turns another half turn, the piston (6) moves forward. The hammer unit (4) is also moved forward and its tip hits the rear end (3) of the tool (2) to form a hammer.
この公知例に於ける欠点は、前記ハンマ一体(4)が動
かなくなることがあることである。A disadvantage of this known example is that the hammer unit (4) may become stuck.
なぜかというと、空気抜穴(9)の存在に原因している
。即ち、ピストン(6)をシリンダーであるハンマ一体
(4)に嵌めるときは、第1図のように、ハンマ一体(
4)に対してピストン(6)を無理に押込むのである。The reason for this is the presence of the air vent hole (9). That is, when fitting the piston (6) into the hammer unit (4), which is a cylinder, as shown in Fig.
4), the piston (6) is forced into it.
すると、密閉室00の部分の空気は次第に圧縮され、ピ
ストン(6)の外周に嵌めであるリングαBが空気抜穴
(9)を越えるとき、圧縮された空気は前記穴(9)を
通って外部に出るから、ピストン(6)とハンマ一体(
4)とが結合されるのである(第1図の仮線の位置が嵌
合した状態)が、この状態で、即ち第1図の仮線の状態
、又は第4図の状態でピストン(6)が猛烈なスピード
で後退すると外部の空気が、前記穴(9)を通って密閉
室a1に流れ込み、その反対にピストン(6)が前進す
るときは、密閉室OI内の空気が空気抜穴(9)を通っ
て外部に流出することになり、この場合はハンマ一体(
4)は全熱動かず、ピストン(6)のみが激しく前後動
するのである。Then, the air in the sealed chamber 00 is gradually compressed, and when the ring αB fitted on the outer periphery of the piston (6) crosses the air vent hole (9), the compressed air passes through the hole (9). Since it comes out outside, the piston (6) and hammer are integrated (
4) are connected (the fitted state indicated by the phantom line in Fig. 1), but in this state, that is, the state shown by the phantom line in Fig. 1, or the state shown in Fig. 4, the piston (6) is connected. ) retreats at a tremendous speed, outside air flows into the sealed chamber a1 through the hole (9), and conversely, when the piston (6) moves forward, the air in the sealed chamber OI flows into the air vent hole. (9) to the outside, and in this case, the hammer is integrated (
4) does not move at all due to heat, and only the piston (6) moves violently back and forth.
よって工夫した本件発明は、前記空気抜穴(9)は、こ
れを中止し、空気抜穴(9)に換えて外部に連通ずるネ
ジ孔O2をハンマ一体(4)のヘッドαJに形成し、こ
れに止ネジa4を螺合したものである次に作用を述べる
。Therefore, in the present invention, the air vent hole (9) is discontinued, and instead of the air vent hole (9), a screw hole O2 communicating with the outside is formed in the head αJ of the hammer integrated (4). A set screw A4 is screwed into this.The operation will be described next.
本発明は、前記のとおりであるから、ハンマ一体(4)
にピストン(6)を挿入するときは、予め、正ネジIを
外して、前記密閉室OIは外部と連通ずる状態としてお
き、その状態でピストン(6)を挿入し密閉室側の間隔
を適当に保って止ネジa4を締め込めば、密閉室a〔は
外部と遮断され、取付けは完了する。Since the present invention is as described above, the hammer integrated (4)
When inserting the piston (6), remove the right screw I in advance so that the sealed chamber OI is in communication with the outside, and then insert the piston (6) in that state and adjust the gap on the sealed chamber side. If the set screw A4 is tightened while maintaining the position, the sealed chamber A is isolated from the outside, and the installation is completed.
本発明は以上の如くであり、これを従前公知のものと比
べると、空気抜穴(9)が形成されていないので、密閉
室OIに空気が流入することがなく、従つ、て、ピスト
ン(6)のみが動いて、ハンマ一体(4)が動かないと
いう従来の欠陥を一掃しつる。The present invention is as described above, and when compared with conventionally known ones, since the air vent hole (9) is not formed, air does not flow into the sealed chamber OI, and therefore, the piston This eliminates the conventional defect that only the hammer (6) moves and the hammer (4) does not move.
