Description

本発明は、岩石や鉱石等の破砕に使用されるジョークラッシャに関する。   The present invention relates to a jaw crusher used for crushing rocks and ores.

岩石や鉱石等の固い被砕物の破砕に使用されるジョークラッシャは、フレームに固定された固定歯と、揺動するスイングジョーに取り付けられ、固定歯との間で下端側出口が狭くなるＶ字形断面の破砕室を形成する動歯とを備え、スイングジョーの下端側背面を一端で支持するトグルプレートの他端を進退可能なトグルブロックで支持し、スイングジョーに取り付けられた動歯を固定歯側へ揺動させて、破砕室に投入される被砕物を固定歯と動歯の間に噛み込んで破砕するものである。   The jaw crusher used for crushing hard crushed objects such as rocks and ores is attached to a fixed tooth fixed to the frame and a swinging swing jaw, and a V-shaped that narrows the lower end exit between the fixed tooth A moving tooth that forms a crushing chamber with a cross-section, and supports the other end of the toggle plate that supports the lower back side of the swing jaw at one end with a toggle block that can be advanced and retracted, and the moving tooth attached to the swing jaw is a fixed tooth The object to be crushed is swung to the side, and the object to be crushed in the crushing chamber is bitten between the fixed tooth and the moving tooth to be crushed.

このようなジョークラッシャでは、進退可能なトグルブロックの背面側に油圧シリンダを接続し、そのピストンロッドの位置を調整することにより、固定歯と動歯間の破砕室の出口間隙を変更できるようにしたものがある。この油圧シリンダは、トグルブロックの背面側への後退を許容して、過負荷を防止する役割もする。   In such a jaw crusher, a hydraulic cylinder is connected to the back side of a toggle block that can be advanced and retracted, and the position of the piston rod is adjusted so that the exit gap of the crushing chamber between the fixed tooth and the moving tooth can be changed. There is what I did. The hydraulic cylinder also serves to prevent overload by allowing the toggle block to move backward on the back side.

従来、前記トグルブロックに接続される油圧シリンダは、フレームの側壁に差し渡された梁部材に支持されており、動歯からスイングジョーに負荷される破砕力の反力は、梁部材を介してフレームで受けられるようになっている（例えば、特許文献１、２参照）。   Conventionally, the hydraulic cylinder connected to the toggle block is supported by a beam member passed to the side wall of the frame, and the reaction force of the crushing force applied to the swing jaw from the moving tooth is via the beam member. It can be received by a frame (see, for example, Patent Documents 1 and 2).

特開平６−２３２８７号公報（第１、２図）JP-A-6-23287 (Figs. 1 and 2) 実公昭５８−４７９４８号公報（第２図）Japanese Utility Model Publication No. 58-47948 (Fig. 2)

上述した油圧シリンダが梁部材を介してフレームに支持された従来のジョークラッシャは、固い被砕物を破砕するときに数百トンもの大きな破砕力が油圧シリンダから加わるので、その反力によって油圧シリンダを直接支持する梁部材に大きな曲げモーメントが発生し、この曲げモーメントがフレームにも作用する。このため、この曲げモーメントによる変形を防止するために、フレームを曲げ剛性の高い厚肉のものとする必要があるので、フレームの重量が重くなり、その製造コストも高くなる問題がある。   In the conventional jaw crusher in which the hydraulic cylinder described above is supported by the frame through the beam member, a large crushing force of several hundred tons is applied from the hydraulic cylinder when crushing a hard crushed object. A large bending moment is generated in the beam member directly supported, and this bending moment also acts on the frame. For this reason, in order to prevent deformation due to this bending moment, it is necessary to make the frame thick with high bending rigidity, so that there is a problem that the weight of the frame becomes heavy and its manufacturing cost increases.

そこで、本発明の課題は、フレームの重量と製造コストを低減できるジョークラッシャを提供することである。   Accordingly, an object of the present invention is to provide a jaw crusher that can reduce the weight and manufacturing cost of the frame.

上記の課題を解決するために、本発明は、フレームに固定された固定歯と、揺動するスイングジョーに取り付けられ、前記固定歯との間で下端側出口が狭くなるＶ字形断面の破砕室を形成する動歯とを備え、前記スイングジョーの下端側背面を一端で支持するトグルプレートの他端を進退可能なトグルブロックで支持し、このトグルブロックの背面側に油圧シリンダを接続したジョークラッシャにおいて、前記油圧シリンダの側部両側に張り出し部を設け、これらの張り出し部を前記フレームの側壁に設けた貫通孔に嵌入して、前記油圧シリンダを前記フレームの側壁に支持した構成を採用した。   In order to solve the above-described problems, the present invention provides a crushing chamber having a V-shaped cross section, which is attached to a fixed tooth fixed to a frame and a swinging swing jaw, and a lower end side outlet narrows between the fixed tooth. And a jaw crusher in which a hydraulic cylinder is connected to the back side of the toggle block. In this embodiment, a projecting portion is provided on both sides of the hydraulic cylinder, and the projecting portion is inserted into a through-hole formed in the side wall of the frame so that the hydraulic cylinder is supported on the side wall of the frame.

すなわち、油圧シリンダの側部両側に張り出し部を設け、これらの張り出し部をフレームの側壁に設けた貫通孔に嵌入して、油圧シリンダをフレームの側壁に支持することにより、大きな破砕力の反力をフレームの側壁に設けた貫通孔の内側面で受けて、フレームに引張、圧縮力のみが作用するようにし、フレームを曲げ剛性の高い厚肉のものとすることなく、その重量と製造コストを低減できるようにした。   That is, by providing projecting portions on both sides of the hydraulic cylinder, inserting these projecting portions into through holes provided on the side wall of the frame, and supporting the hydraulic cylinder on the side wall of the frame, the reaction force of a large crushing force Is received by the inner surface of the through-hole provided in the side wall of the frame so that only the tensile and compressive force acts on the frame, and the weight and manufacturing cost are reduced without making the frame thick with high bending rigidity. I was able to reduce.

前記油圧シリンダの側部両側の張り出し部を別体の張り出し部材で形成し、この張り出し部材を前記油圧シリンダの側部に着脱可能とすることにより、フレームの側壁の間隔よりも幅寸法の小さい油圧シリンダをクレーン等で吊り下げてフレーム内に入れ、別体の張り出し部材をフレームの側壁の外側から貫通孔に嵌入して、油圧シリンダの側部に着脱するようにし、油圧シリンダのフレームへの取り付け作業を容易にすることができる。   The projecting portions on both sides of the hydraulic cylinder are formed by separate projecting members, and the projecting members can be attached to and detached from the side portions of the hydraulic cylinder, so that the hydraulic pressure is smaller than the distance between the side walls of the frame. The cylinder is suspended by a crane or the like and placed in the frame, and a separate overhang member is inserted into the through hole from the outside of the side wall of the frame so that it can be attached to and detached from the side of the hydraulic cylinder. Work can be facilitated.

前記油圧シリンダを前記フレームの側壁に回動可能に支持することにより、油圧シリンダを回動させて、その点検等を容易に行なうことができる。   By supporting the hydraulic cylinder on the side wall of the frame so as to be rotatable, the hydraulic cylinder can be rotated for easy inspection and the like.

本発明のジョークラッシャは、油圧シリンダの側部両側に張り出し部を設け、これらの張り出し部をフレームの側壁に設けた貫通孔に嵌入して、油圧シリンダをフレームの側壁に支持するようにしたので、大きな破砕力の反力をフレームの側壁に設けた貫通孔の内側面で受けて、フレームに引張、圧縮力のみが作用するようにし、フレームを曲げ剛性の高い厚肉のものとすることなく、その重量と製造コストを低減することができる。   The jaw crusher of the present invention is provided with overhang portions on both sides of the hydraulic cylinder, and these overhang portions are fitted into through holes provided in the side wall of the frame so that the hydraulic cylinder is supported on the side wall of the frame. Without receiving a reaction force of a large crushing force on the inner surface of the through hole provided on the side wall of the frame so that only the tensile and compressive force acts on the frame, the frame does not have a thick wall with high bending rigidity The weight and manufacturing cost can be reduced.

前記油圧シリンダの側部両側の張り出し部を別体の張り出し部材で形成し、この張り出し部材を前記油圧シリンダの側部に着脱可能とすることにより、フレームの側壁の間隔よりも幅寸法の小さい油圧シリンダをクレーン等で吊り下げてフレーム内に入れ、別体の張り出し部材をフレームの側壁の外側から貫通孔に嵌入して、油圧シリンダの側部に着脱するようにし、油圧シリンダのフレームへの取り付け作業を容易にすることができる。   The projecting portions on both sides of the hydraulic cylinder are formed by separate projecting members, and the projecting members can be attached to and detached from the side portions of the hydraulic cylinder, so that the hydraulic pressure is smaller than the distance between the side walls of the frame. The cylinder is suspended by a crane or the like and placed in the frame, and a separate overhang member is inserted into the through hole from the outside of the side wall of the frame so that it can be attached to and detached from the side of the hydraulic cylinder. Work can be facilitated.

前記油圧シリンダを前記フレームの側壁に回動可能に支持することにより、油圧シリンダを回動させて、その点検等を容易に行なうことができる。   By supporting the hydraulic cylinder on the side wall of the frame so as to be rotatable, the hydraulic cylinder can be rotated for easy inspection and the like.

以下、図面に基づき、本発明の実施形態を説明する。このジョークラッシャは、図１および図２に示すように、フレーム１の前壁１ａに固定された固定歯２と、揺動するスイングジョー３に取り付けられ、固定歯２との間で下端側出口が狭くなるＶ字形断面の破砕室４を形成する動歯５とを備え、スイングジョー３の下端側背面を一端で支持するトグルプレート６の他端が進退可能なトグルブロック９で支持されており、動歯５を取り付けたスイングジョー３を揺動させることにより、破砕室４に投入される被砕物を固定歯２と動歯５の間に噛み込んで破砕する。トグルブロック９の背面側には油圧シリンダ７が接続され、そのピストンロッド７ａの位置を調整することにより、固定歯２と動歯５間の破砕室４の出口間隙を変更できるようになっており、フレーム１の両側の側壁１ｂは、前端側を前壁１ａで連結され、後端側をパイプ１ｃで連結されている。なお、油圧シリンダ７は、トグルブロック９の背面側への後退を許容して、過負荷を防止する役割もする。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, this jaw crusher is attached to a fixed tooth 2 fixed to a front wall 1 a of a frame 1 and a swinging swing jaw 3, and a lower end side outlet between the fixed tooth 2. And a moving tooth 5 that forms a crushing chamber 4 having a V-shaped cross-section, and the other end of a toggle plate 6 that supports the lower end side rear surface of the swing jaw 3 at one end is supported by a toggle block 9 that can be advanced and retracted. By swinging the swing jaw 3 to which the moving tooth 5 is attached, the object to be crushed in the crushing chamber 4 is caught between the fixed tooth 2 and the moving tooth 5 and crushed. A hydraulic cylinder 7 is connected to the back side of the toggle block 9, and the clearance of the crushing chamber 4 between the fixed tooth 2 and the moving tooth 5 can be changed by adjusting the position of the piston rod 7a. The side walls 1b on both sides of the frame 1 are connected at the front end side by the front wall 1a and at the rear end side by the pipe 1c. The hydraulic cylinder 7 also serves to prevent overload by allowing the toggle block 9 to move backward to the back side.

前記スイングジョー３は、上端側をプーリ８の偏心軸８ａに枢着され、その下端側背面を支持するトグルプレート６は、揺動するスイングジョー３に追随するように、円筒面座１０を介してトグルブロック９との間に突き合わされている。また、スイングジョー３の揺動によってトグルプレート６が落下しないように、スイングジョー３の下端部とトグルブロック９とは引張コイルばね１１で連結されている。したがって、偏心軸８ａに枢着されたスイングジョー３の上端側は円軌跡を描き、トグルプレート６に支持された下端側は、トグルプレート６の長さを半径とする円弧運動をする。なお、油圧シリンダ７の背面側にはカバー１２が取り付けられ、このカバー１２に油圧シリンダ７のピストンロッド７ａの位置を検出する変位センサ１３が取り付けられている。   The swing jaw 3 is pivotally attached to the eccentric shaft 8a of the pulley 8 at the upper end side, and the toggle plate 6 that supports the back surface of the lower end side is provided through the cylindrical seat 10 so as to follow the swinging swing jaw 3. And a toggle block 9. Further, the lower end of the swing jaw 3 and the toggle block 9 are connected by a tension coil spring 11 so that the toggle plate 6 does not fall due to the swing of the swing jaw 3. Therefore, the upper end side of the swing jaw 3 pivotally attached to the eccentric shaft 8a draws a circular locus, and the lower end side supported by the toggle plate 6 performs an arc motion with the length of the toggle plate 6 as a radius. A cover 12 is attached to the back side of the hydraulic cylinder 7, and a displacement sensor 13 for detecting the position of the piston rod 7 a of the hydraulic cylinder 7 is attached to the cover 12.

図３および図４に示すように、前記油圧シリンダ７の側部両側には耳部１４が設けられ、これらの耳部１４に取り付けられた別体の張り出し部材１５が、フレーム１の両側の側壁１ｂに設けられた貫通孔１６に嵌入されて、油圧シリンダ７が両側壁１ｂに支持されている。したがって、油圧シリンダ７から加わる破砕力の反力は側壁１ｂの貫通孔１６の内側面で受けられるので、フレーム１には引張、圧縮力のみが作用し、曲げモーメントが作用することはない。   As shown in FIGS. 3 and 4, ears 14 are provided on both sides of the hydraulic cylinder 7, and separate projecting members 15 attached to these ears 14 are provided on the side walls on both sides of the frame 1. The hydraulic cylinder 7 is supported on both side walls 1b by being fitted into a through hole 16 provided in 1b. Therefore, since the reaction force of the crushing force applied from the hydraulic cylinder 7 is received by the inner surface of the through hole 16 of the side wall 1b, only the tensile and compressive force acts on the frame 1, and no bending moment acts.

前記張り出し部材１５は、貫通孔１６に嵌入される円筒部１５ａと、油圧シリンダ７の耳部１４に設けられた嵌合穴１４ａに嵌合される凸部１７が形成された底部１５ｂと、側壁１ｂに取り付けられるフランジ部１５ｃを有するカップ状に形成され、底部１５ｂがボルト１８で耳部１４に着脱されるとともに、フランジ部１５ｃが側壁１ｂの外側にボルト１９で取り付けられるようになっている。   The projecting member 15 includes a cylindrical portion 15a fitted into the through hole 16, a bottom portion 15b formed with a convex portion 17 fitted into a fitting hole 14a provided in the ear portion 14 of the hydraulic cylinder 7, and a side wall. It is formed in a cup shape having a flange portion 15c attached to 1b, the bottom portion 15b is attached to and detached from the ear portion 14 with a bolt 18, and the flange portion 15c is attached to the outside of the side wall 1b with a bolt 19.

前記フランジ部１５ｃには、破砕力の反力として作用する引張、圧縮力によるボルト１９の剪断を防止するために、剪断防止ピン２０が２箇所に装着されている。また、耳部１４の嵌合穴１４ａの底と張り出し部材１５の底部１５ｂには、両者を位置決め固定するためのセンターピン２１ａとサイドピン２１ｂが取り付けられ、後述する油圧シリンダ７に張り出し部材１５を仮固定するためのピン穴２２も設けられている。   The flange portion 15c is provided with two anti-shear pins 20 in order to prevent the bolt 19 from being sheared by a tensile or compressive force acting as a reaction force of the crushing force. Further, a center pin 21a and a side pin 21b are attached to the bottom of the fitting hole 14a of the ear portion 14 and the bottom portion 15b of the overhanging member 15, and the overhanging member 15 is attached to the hydraulic cylinder 7 described later. A pin hole 22 for temporary fixing is also provided.

以下に、前記油圧シリンダ７をフレーム１に取り付ける手順を説明する。まず、油圧シリンダ７をフレーム１の側壁１ｂの内側に吊り下げて、張り出し部材１５を側壁１ｂの外側から貫通孔１６に嵌入し、前記ピン穴２２に仮固定用のピンを挿入して、張り出し部材１５を油圧シリンダ７の耳部１４に仮固定する。こののち、センターピン２１ａとサイドピン２１ｂで両者を位置決め固定し、ボルト１８で張り出し部材１５を耳部１４に取り付ける。最後に、張り出し部材１５のフランジ部１５ｃをボルト１９でフレーム１の側壁１ｂに取り付けるとともに、フランジ部１５ｃに剪断防止ピン２０を装着することにより、油圧シリンダ７を容易にフレーム１に取り付けることができる。   The procedure for attaching the hydraulic cylinder 7 to the frame 1 will be described below. First, the hydraulic cylinder 7 is suspended inside the side wall 1b of the frame 1, the overhanging member 15 is fitted into the through hole 16 from the outside of the side wall 1b, and a pin for temporary fixing is inserted into the pin hole 22 to overhang. The member 15 is temporarily fixed to the ear portion 14 of the hydraulic cylinder 7. After that, the center pin 21 a and the side pin 21 b are positioned and fixed, and the projecting member 15 is attached to the ear portion 14 with the bolt 18. Finally, the hydraulic cylinder 7 can be easily attached to the frame 1 by attaching the flange portion 15c of the overhanging member 15 to the side wall 1b of the frame 1 with the bolt 19 and attaching the shear prevention pin 20 to the flange portion 15c. .

図５（ａ）、（ｂ）は、前記油圧シリンダ７を点検するために回動させた状態を示す。図５（ａ）は、変位センサ１３が取り付けられた後端側を上向に回動させた状態、図５（ｂ）は、トグルブロック９が取り付けられた先端側を上向に回動させた状態である。これらの回動状態とするためには、前記ボルト１９と剪断防止ピン２０を取り外して、油圧シリンダ７と張り出し部材１５を一体で回動すればよく、点検作業中は、何本かのボルト１９を張り出し部材１５のフランジ部１５ｃに装着して、これらの回動状態を仮固定すればよい。   FIGS. 5A and 5B show a state in which the hydraulic cylinder 7 is rotated for inspection. 5A shows a state in which the rear end side to which the displacement sensor 13 is attached is turned upward, and FIG. 5B shows a state in which the front end side to which the toggle block 9 is attached is turned upward. It is in the state. In order to achieve these rotation states, the bolt 19 and the shear prevention pin 20 are removed, and the hydraulic cylinder 7 and the overhanging member 15 may be rotated integrally. Is attached to the flange portion 15c of the overhanging member 15 to temporarily fix these rotating states.

上述した実施形態では、油圧シリンダの側部両側に張り出し部を形成する張り出し部材をカップ状のものとしたが、この張り出し部材の形状はカップ状のものに限定されることはない。   In the embodiment described above, the projecting member that forms the projecting portions on both sides of the hydraulic cylinder is a cup-shaped member, but the shape of the projecting member is not limited to a cup-shaped member.
