本発明は土木作業機の改良に関するものであつ
て、その目的は1台の土木作業機にて2種類の作
業を連続的に行なうことの出来る土木作業機を提
供することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of civil engineering working machines, and its purpose is to provide a civil engineering working machine that can perform two types of work continuously with one civil engineering working machine. There is a particular thing.
一般に土木作業にあつては通常2種以上の作業
が組合されて行なわれる場合が多い。例えば採石
作業においてはさく岩作業と掘削作業が組合せて
行われる。又ビルデイング等建造物の解体作業に
おいては、鉄筋コンクリートの破砕作業と破砕さ
れたコンクリート塊の処理作業が組合せて行なわ
れる。 In general, civil engineering work often involves a combination of two or more types of work. For example, in quarrying operations, rock drilling and excavation operations are performed in combination. Furthermore, in the demolition work of structures such as buildings, the work of crushing reinforced concrete and the work of processing crushed concrete blocks are performed in combination.
しかして土木作業機としては例えば掘削機、さ
く岩機等各作業の専用機として作られる場合が多
い。従つて、上記の様に2種の作業が組合わされ
て行われる場合、例えば採石作業においてさく岩
機作業と掘削作業が連続して行われる場合におい
ては、さく岩機と掘削機を用意しなければならな
い。 However, civil engineering work machines are often made as dedicated machines for various types of work, such as excavators and rock drills. Therefore, when two types of work are performed in combination as mentioned above, for example, when rock drilling work and excavation work are performed consecutively in quarrying work, a rock drilling machine and an excavator must be prepared. Must be.
しかして各作業毎にその専用機を使用しての作
業はその設備費及び人件費がかさむことは勿論の
こととして効率の良い作業が得られない。 However, using a dedicated machine for each task not only increases equipment costs and personnel costs, but also does not provide efficient work.
特に上記の様な作業の非能率は例えば路地にお
ける道路の補修作業の様にその作業スペースが規
制される作業現場において顕著に表わされる。 In particular, the above-mentioned work inefficiency is particularly noticeable in work sites where the work space is restricted, such as road repair work in an alley.
上記の様な不都合を解消する方法としては次の
2つの方法が試みられている。 The following two methods have been attempted to resolve the above-mentioned inconveniences.
その1つは複数の作業機をアタツチメントとし
て用意し、各作業に応じて作業機を取り替える方
法である。 One method is to prepare a plurality of work machines as attachments and replace the work machines according to each task.
しかしてこの様に複数の作業機をアタツチメン
トとして用意し、作業に応じて取り替え使用する
方法にあつては、各作業の種類に応じ専用機を整
える必要がないため上記の様に充分な作業スペー
スが得られない作業現場において作業を行なうこ
とが出来る点を長所として認めることが出来るも
のの作業の変化に応じて作業機を取り替えなけれ
ばならず、その取り替え作業に面倒を生ずる点に
短所を有する。 However, in the case of methods such as levers, where multiple work machines are prepared as attachments and used interchangeably depending on the work, there is no need to prepare dedicated machines for each type of work, so sufficient work space is required as described above. Although the advantage of this method is that it allows work to be carried out at work sites where it is difficult to obtain the desired conditions, it has a disadvantage in that the work equipment must be replaced in response to changes in the work, and the replacement work is troublesome.
もう1つの方法は1台の土木作業機に複数本の
ブームを設け、各ブームに対して夫々作業機を取
付ける方法である。 Another method is to provide one civil engineering work machine with a plurality of booms and attach a work machine to each boom.
しかしてこの様に複数本のブームを設ける方法
は上記方法の様に各作業毎に作業機を取り替える
必要のない点を長所として認めることが出来る反
面、複数本のブームを有することにより、土木作
業機のコストが高くなる点、及び例えば旋回作業
においてその旋回方向に制約を受ける等その作業
性が低下する点に短所を有する。 However, the method of installing multiple booms like the lever has the advantage that it does not require replacing the work equipment for each work like the above method, but on the other hand, having multiple booms makes it easier to carry out civil engineering work. This method has disadvantages in that the cost of the machine is high and that the workability is reduced, for example, because the turning direction is restricted during turning work.

したことにある。 That is, the present invention is capable of performing two types of work in succession with one civil engineering work machine by reversibly installing two types of work machines at the tip of the boom. The main feature of the present invention is that a fork is formed at the tip of the boom, and a stick boom with two types of work equipment attached to both ends of the fork is rotatable in the vertical direction. One end of a link arm formed in an approximately semicircular arc shape is pivotally connected to the vicinity of the tip of the fork, and the other end is pivotally connected to the stick boom via an auxiliary arm. A hydraulic mechanism is interposed between the bottom portion of the arm and a portion near the base of the boom, and the step boom is rotated in the vertical direction through the expansion and contraction action of the hydraulic mechanism.
