Description
【０００１】[0001]
本考案は油圧式パワ−ショベル等の作業機をビル建築現場の地下の杭頭処理等 に適するように改良したブレ−カ型杭頭処理機に関する。 The present invention relates to a breaker type pile head processing machine in which a working machine such as a hydraulic power shovel is improved to be suitable for underground pile head processing at a building construction site.
【０００２】[0002]
ビル建築等の地下基礎工事においては、建物を支える強度部材として、または 軟弱地盤を改良して安定させるために、コンクリ−ト製、あるいは鋼管の杭を地 中に打ち込むか、ボ−リングで事前に柱状の孔を掘削したあとにコンクリ−トを 流し込んで、杭を地下に形成する場所打ち杭がよく使用されている。この杭には 基礎工事が進展するにつれて頭部の一部を解体する杭頭処理と云う工程がある。 前記杭頭処理はビルの解体工事、建て替え工事など、旧杭を除去する場合にも行 われるが、処理能力が１人当たり１〜２本／日と効率が悪く、工期のネックにな っている。すなわち、現状の杭頭処理は人手と部分的にパワ−ショベルやブレ− カに頼っており、鉄筋入りの杭の場合、 回りのコンクリ−トのハツリは人手、 またはブレ−カ付きパワ−ショベルにより、 鉄筋の溶断は人手により、中心部 はパワ−ショベルのバケットにより打撃して破壊すると云う手順で行っている。 In the case of underground foundation work such as building construction, concrete-made or steel pipe piles are driven into the ground or drilled beforehand in order to strengthen the structure or to improve and stabilize the soft ground. Cast-in-place piles are often used in which concrete is poured after drilling a columnar hole to form a pile underground. This pile has a process called pile head treatment that dismantles a part of the head as the foundation work progresses. The pile head treatment is also performed when removing old piles such as in demolition work and rebuilding work of a building, but the processing capacity is inefficient at 1-2 per person / day, which is a bottleneck in the construction period. . In other words, the current pile head treatment partially depends on power shovels and breakers in combination with human power, and in the case of piles with reinforcing bars, the chisel of the surrounding concrete is manual or power shovels with breakers. According to the procedure, the melting of the rebar is performed manually and the center part is hit by a bucket of a power shovel and destroyed.
【０００３】[0003]
しかしながら、上記のような手順で行う場合、人手による作業が多いため効率 が悪く、また、杭頭処理が行われている上方では建方工事等が並行して行われる ことがあり、これによる落下物等で極めて危険であるため、一日も早い機械化が 望まれている。 However, if the above procedure is performed, there is a lot of manual work, which is inefficient, and erection work, etc., may be performed in parallel above the pile head treatment, causing a fall. Since it is extremely dangerous for things, mechanization as soon as possible is desired.
【０００４】 本考案はこれに鑑み、杭頭処理を効率良く行え、人手作業を廃止、またはでき る限り少なくすることのできるブレ−カ型杭頭処理機を提供して従来技術の持つ 欠点の解消を図ることを目的としてなされたものである。In view of the above, the present invention provides a breaker type pile head processing machine that can efficiently perform pile head processing and eliminate or reduce manual work as much as possible. It was made for the purpose of resolution.

【０００８】 以下、本考案の請求項１を図１乃至図３に示す実施例を参照して説明する。請 求項１にかかるブレ−カ型杭頭処理機１は下部走行体２１の上部の旋回体２２に 起伏自在なブ−ム２３の基端を設け、ブ−ム２３の先端に前後方向に回動自在な ア−ム２４を設けた油圧式建設機械２０において、該ア−ム２４の下端に、杭頭 ２５の回りを囲む固定リング２を設け、該固定リング２の上部には旋回モ−タ３ を、下部には回転可能な回転リング４をそれぞれ設け、該回転リング４には刃先 ６が杭頭２５の外周に接触可能なブレ−カ５を設けたもので構成され、請求項４ は請求項１において前記ブレ−カ５は一対で互いに対向する位置に設けたもので 構成され、請求項５は請求項４において前記回転リング２には互いに対向する一 対のガスバ−ナ７を前記ブレ−カ５とは離れた位置に設けたもので構成されてい る。Hereinafter, claim 1 of the present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. The breaker type pile head processing machine 1 according to claim 1 is provided with a base end of a boom 23 which can be raised and lowered on an upper swing body 22 of a lower traveling body 21, and a front end of the boom 23 in the front-back direction. In a hydraulic construction machine 20 provided with a freely rotatable arm 24, a fixing ring 2 surrounding the pile head 25 is provided at the lower end of the arm 24, and a swivel model is provided above the fixing ring 2. And a rotary ring 4 which is rotatable at a lower portion thereof, and the rotary ring 4 is provided with a breaker 5 capable of contacting the cutting edge 6 with the outer periphery of the pile head 25.

【０００９】 図１に示す油圧式建設機械２０は本来のパワ−ショベルの作業機のうち、バケ ットの代わりにブレ−カ型杭頭処理機１を装着したものである。したがって下部 走行体２１の上部に設けられた旋回体２２にはブ−ム２３があってブ−ムシリン ダ２６の伸縮により起伏するようになっており、また、ブ−ム２３の先端にはア −ム２４がア−ムシリンダ２７の伸縮により前後方向に回動可能となっている点 は従来と全く同じである。本考案にかかるブレ−カ型杭頭処理機１はア−ム２４ の先端にブラケット８を介して取付けられたもので、ア−ム２４に設けられたリ ングシリンダ９の伸縮により上下に回動できるようになっている。固定リング２ の下側には前記旋回モ−タ３の回転で回転する公知構造のサ−クルベアリング１ ０があって、その下に回転リング４が重なる形状に設けられている。そしてこれ ら各リング２、４内には処理する杭頭２５を回りから囲む形で収容するようにな っている。回転リング４の下側には円弧状で、かつ左右一対のブレ−カ押付用リ ンク１１，１１が回転リング４に一端をピン等により回動自在に支持され、他端 は一方が一本のブレ−カ用シリンダ１２のロッド側とピン１１ａにより、他方が ボトム側とピン１１ｂによりそれぞれ連結されている。これらリンク１１、１１ には内側にそれぞれブレ−カ５が取付ピン１３により固着され、両側の刃先６を 互いに向き合わせるように杭頭２５の周囲に向けて、ブレ−カ５による反力を打 ち消すようにしてある。そこでブレ−カ用シリンダ１２を伸長させれば、刃先６ が杭頭２５の外周から離れ、収縮させれば杭頭２５に近づいて接触できるように なっている。図３中、１４はブレ−カ用シリンダ１２の伸縮によるリンク１１の 揺動の際のストッパ兼ガイドである。なお、回転リング４には必要に応じてブレ −カ５の位置とは直角方向に一対のガスバ−ナ７を装着できるようにしてある。 各図中、２８は鉄筋、または鋼管を示す。The hydraulic construction machine 20 shown in FIG. 1 is a working machine of an original power shovel, in which a breaker type pile head processing machine 1 is mounted instead of a bucket. Therefore, the revolving structure 22 provided on the upper part of the lower traveling structure 21 has a boom 23 which is undulated by the expansion and contraction of the boom cylinder 26, and the tip of the boom 23 has an arm. The point that the arm 24 is rotatable in the front-rear direction by the expansion and contraction of the arm cylinder 27 is exactly the same as the conventional one. The breaker type pile head processing machine 1 according to the present invention is attached to the tip of the arm 24 through the bracket 8 and is rotated up and down by the extension and contraction of the ring cylinder 9 provided in the arm 24. You can move. Below the fixed ring 2, there is provided a circular bearing 10 having a known structure which is rotated by the rotation of the swivel motor 3, and a rotary ring 4 is provided below the circular bearing 10 so as to overlap therewith. The pile heads 25 to be processed are housed in the rings 2 and 4 so as to surround them. An arcuate pair of left and right breaker pressing links 11, 11 is supported on the lower side of the rotary ring 4 by the rotary ring 4 such that one end is rotatably supported by a pin and the other end is one. The breaker cylinder 12 is connected to the rod side by a pin 11a, and the other is connected to the bottom side by a pin 11b. The breakers 5 are fixed to the insides of these links 11 and 11 by mounting pins 13, respectively, and the reaction force by the breakers 5 is applied toward the periphery of the pile head 25 so that the cutting edges 6 on both sides face each other. It is designed to be erased. Therefore, when the breaker cylinder 12 is extended, the blade edge 6 is separated from the outer periphery of the pile head 25, and when it is contracted, the blade tip 6 is brought closer to the pile head 25 so that they can come into contact therewith. In FIG. 3, reference numeral 14 is a stopper / guide when the link cylinder 11 swings due to expansion and contraction of the breaker cylinder 12. Incidentally, a pair of gas burners 7 can be attached to the rotary ring 4 at right angles to the position of the breaker 5 if necessary. In each figure, 28 shows a reinforcing bar or a steel pipe.
【００１０】 つぎに作用を説明する。まず、処理する杭頭２５の上から杭頭２５が中心に来 るようにブレ−カ型杭頭処理機１の固定リング２および回転リング４の内径内に 降ろし水平に位置させる。これにより杭頭２５の外囲にブレ−カ５の刃先６を接 触させて打撃を加えながら、旋回モ−タ３を回転させると、固定リング２に対し て回転リング４が回転するので、杭頭２５のコンクリ−ト部が全周に亘り破壊さ れる。この場合、一対のブレ−カ５，５を対面するように配置しているので反力 が打ち消され、ブレ−カ型杭頭処理機１の振動も少なくなる。そして鉄筋や鋼管 ２８等は回転リング４に設けられた一対のガスバ−ナ７，７により溶断する。こ のようにして周りを破壊された杭頭２５は油圧式建設機械２０の走行力（牽引力 ）を利用して倒すことで処理が完了する。Next, the operation will be described. First, the pile heads 25 to be processed are lowered and placed horizontally within the inner diameters of the fixed ring 2 and the rotary ring 4 of the breaker type pile head processing machine 1 so that the pile heads 25 come to the center. As a result, when the turning motor 3 is rotated while the blade edge 6 of the breaker 5 is in contact with the outer periphery of the pile head 25 and the impact is applied, the rotary ring 4 rotates with respect to the fixed ring 2. The concrete portion of the pile head 25 is destroyed over the entire circumference. In this case, since the pair of breakers 5 and 5 are arranged so as to face each other, the reaction force is canceled and the vibration of the breaker type pile head processing machine 1 is reduced. Then, the rebar and the steel pipe 28 are fused by the pair of gas burners 7, 7 provided on the rotary ring 4. The pile head 25 whose surroundings have been destroyed in this way is completed by using the traveling force (traction force) of the hydraulic construction machine 20 to knock it down.
【００１１】 本考案の請求項２は図４に示すように、請求項１がア−ム２４の先端にブレ− カ型杭頭処理機１を設けたのに対して、ア−ム２４を用いず直接、ブ−ム２３の 先端に設けた点が相違するが、生ずる効果は請求項１の場合と同様であるので詳 細および作用説明は省略する。According to claim 2 of the present invention, as shown in FIG. 4, the arm 24 is provided with the breaker type pile head processing machine 1 at the tip of the arm 24, whereas the arm 24 is provided. The difference is that it is provided directly at the tip of the boom 23 without using it, but the effect that occurs is the same as in the case of claim 1, so the details and explanation of the operation will be omitted.
