この発明は、パワーショベルのアタッチメントとしてコ
ンクリート構築物特にコンクリート建造物の解体工事に
好適に使用しうる破砕装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crushing device that can be suitably used as an attachment for a power shovel in demolition work of concrete structures, particularly concrete structures.
近時、コンクリート構造物の解体に当っては、従来の衝
撃による騒音、振動音を発する装置に代って、圧潰によ
る低騒音の装置が開発されている。In recent years, when demolishing concrete structures, low-noise equipment has been developed that uses crushing to replace conventional equipment that generates noise and vibration noise due to impact.
これら装置は、解体すべき部分を、対向して設けた２個
一組のジョ一部材で挟圧して圧潰するものであって、２
個のジョ一部材のそれぞれを、別々の油圧シリンダによ
って直接に可動する形式と一方のジョ一部材を固定し、
他のジョ一部材のみを油圧シリンダ゛によって可動する
形式とに大別される。These devices crush the part to be disassembled by squeezing it with a set of two jaw members installed opposite each other.
Each of the two jaw members is directly movable by a separate hydraulic cylinder, and one jaw member is fixed,
It is roughly divided into a type in which only the other jaw members are moved by a hydraulic cylinder.
しか呟前者は、２個のジョ一部材の動きが平均して行わ
れないため、出力に比較して効率が低いという欠点があ
るし、また後者は十分な挟圧力が得られないという欠点
がある。However, the former has the disadvantage that the efficiency is low compared to the output because the movement of the two jaw members is not averaged, and the latter has the disadvantage that sufficient clamping force cannot be obtained. be.

傾向があるため、円滑な切断が達成されないという欠点
がある。On the other hand, these crushing devices are equipped with a cutting blade on a part of the opposing edge of each jaw member as a cutting mechanism for reinforcing bars and steel frames stretched in concrete, but this type of cutting mechanism is However, the reinforcing bar or steel frame sandwiched between the two jaw members tends to escape to the outside as the jaw members are closed, so there is a drawback that smooth cutting cannot be achieved.

内縁に設けることによってその目的を達成しうろことを
見出し、この発明をなすに至った。The inventor conducted various research in order to improve the drawbacks of conventional crushing equipment as described above and to develop a device that can efficiently crush concrete and cut reinforcing bars and steel frames. It accomplishes this purpose by simultaneously opening and closing the parts via a series of linkages connected to a single hydraulic cylinder, and by providing reinforcing bars, steel frames, and cutting blades on the inner edge of each jaw member in contact with the basic tip. He discovered scales and came up with this invention.
次にこの発明の実施例を図面について説明すると、２個

うになっている。These jaw members 1, 1 apply a clamping force of 4 to the inner surface of their tips.
, 4, and furthermore, a notch is provided in the portion from the clamping force 4 to the pivot point, and a notch edge 5 is provided, and as shown in the figure, the clamping blades 4, 4 are joined with each other and cut. The cutting blade edge 5 is adapted to engage with a reinforcing bar, a steel frame, and a cutting blade 6 provided on the distal end surface of the base body 2.

軸着して一連のリンク機構１２が形成されている。Links 7.7 of the same length are attached to the other ends (upper ends) of these jaw members 1, 1 by shafts 8, and the other ends of these links 7.7 are a pushing mechanism 9 provided on the base body 2. A series of link mechanisms 12 are formed by being pivotally attached to a crosshead portion 11 provided at the tip of a hydraulic piston rod 10.
また、基体２の他端（上端）には取付板１３，１３がボ
ルト締によりパワーショベルのブーム先端を固着できる
ように取り付けられている。Furthermore, mounting plates 13, 13 are attached to the other end (upper end) of the base body 2 so that the tip of the boom of a power shovel can be fixed thereto by tightening bolts.
１４は油圧シリンダである。14 is a hydraulic cylinder.
さらに、この装置の首部と基部を相互に分離可能にボル

に引いて両ジョ一部材１，１の先端を第１図の鎖線で示
す状態に拡開させ、破砕すべき所要部な挟圧力４，４の
間に位置させる。That is, the hydraulic piston rod is pulled upward in the figure via the operating mechanism to expand the ends of both jaw members 1, 1 to the state shown by the chain lines in FIG. Position it between 4.

抱き込むようにして押圧切断する。In addition, when it is necessary to cut reinforcing bars or steel frames buried in concrete, it is pushed into the contact area between the jaw member and the basic tip by the opening and closing action of the jaw members 1, 1, and Between the cutting edge 5 provided at the base of the reinforcing bar, the steel frame, and the cutting blade 6 provided on the tip surface of the base,
Hold it in place and press it to cut.

して効率的な圧潰を行うことができる。Although the figure shows an example in which the cutting edge 5 and the cutting blade 6 are perpendicular to the piston rod 10, they do not necessarily have to be perpendicular and may be installed diagonally. Needless to say, as described above, the present invention connects the other ends of both jaw members 1, 1 whose intermediate portions are pivotally supported to a single pushing mechanism via the link mechanism 12, and expands symmetrically. Since the clamping force is applied by opening the link 7.7, the maximum clamping force can be applied using the lever force that acts in the same manner as the wedge driving action between the other ends of the two jaw members by the link 7.7. , and since both jaw members 1, 1 are always held in symmetrical positions with the base body 2 as the axis via the link mechanism 11, it is possible to apply pressure evenly to both sides of the concrete member and perform efficient crushing. can.
しかも鉄筋や鉄骨を切断する場合、前記したように従来

断すべき鉄筋や鉄骨が逃げるのを防ぐことができ、効率
よく切断することができる。Moreover, when cutting reinforcing bars and steel frames, the reinforcing bars and steel frames to be cut can be prevented from escaping because the reinforcing bars and steel frames to be cut can be prevented from escaping, and can be cut efficiently, instead of using the conventional push-cutting method as described above.
また押送機構９である油圧シリンダ１４は、首振り型と

ース等にも無理がかからず作業に便利である等多くの利
点がある。In addition, the hydraulic cylinder 14, which is the pushing mechanism 9, does not need to be of an oscillating type and can be fixedly installed on the base body 2, so it has many advantages such as being convenient for work without straining the pressure oil hose etc. .
さらに、この装置において首部と基部の結合部をたてよ
