本発明は、下部走行体の上部に上部旋回体を旋回軸受を介して旋回可能に備えたショベル系掘削機で、下部走行体と上部旋回体とを分解することができる分解型建設機械に関するものである。 TECHNICAL FIELD The present invention relates to an excavator excavator having an upper revolving unit that can be revolved via a swivel bearing on an upper part of a lower traveling unit, and relates to a disassembly type construction machine that can disassemble the lower traveling unit and the upper revolving unit. It is.
従来、建設機械は、図１２に示されるように、上部旋回体２０と下部走行体２１との間に旋回軸受２２が配設され、該旋回軸受２２を介して、下部走行体２１の上部に上部旋回体２０が旋回可能に配設されている。 Conventionally, as shown in FIG. 12, in a construction machine, a swing bearing 22 is disposed between an upper swing body 20 and a lower travel body 21, and the upper portion of the lower travel body 21 is interposed via the swing bearing 22. The upper turning body 20 is disposed so as to be turnable.
前記旋回軸受２２は、内輪２３と外輪２４との間に複数の転動子２５を介装したもので、内輪２３が上部旋回体２０の内側から複数の取付けボルト２６で固着されている。 The slewing bearing 22 includes a plurality of rolling elements 25 interposed between an inner ring 23 and an outer ring 24, and the inner ring 23 is fixed by a plurality of mounting bolts 26 from the inside of the upper slewing body 20.

Therefore, it is necessary to lift the weight of the bolt, collar and upper tool. The workability of was bad.
下記特許文献は簡単な構造で、効率よく上部旋回体と下部走行体とを分割でき、輸送に便利な建設機械を提供するものとして提案されたものである。
図１１に示すように、この特許文献１は、上部旋回体２と下部走行体３との間に旋回軸受４を配設した建設機械において、前記旋回軸受４の下部外周にフランジ部１２を形成し、該フランジ部を前記下部走行体に連結ボルト１３にて締結した。 As shown in FIG. 11, this Patent Document 1 is a construction machine in which a swing bearing 4 is arranged between an upper swing body 2 and a lower traveling body 3, and a flange portion 12 is formed on the outer periphery of the lower portion of the swing bearing 4. Then, the flange portion was fastened to the lower traveling body with a connecting bolt 13.
旋回軸受４は、内輪５と外輪６との間に複数の転動子７を介装したもので、回転する内輪５が、上部旋回体２の内側から複数の取付けボルト８で固着される。 The slewing bearing 4 includes a plurality of rolling elements 7 interposed between an inner ring 5 and an outer ring 6, and the rotating inner ring 5 is fixed by a plurality of mounting bolts 8 from the inside of the upper swing body 2.
また、外輪６の下方には、ブラケット９が配設され、該ブラケット９の上部フランジ１０と、外輪６とは複数の取付けボルト１１で固着される。 A bracket 9 is disposed below the outer ring 6, and the upper flange 10 of the bracket 9 and the outer ring 6 are fixed to each other with a plurality of mounting bolts 11.
ブラケット９は、下部外周に、前記外輪６よりも大径の下部フランジ部１２が形成され、この下部フランジ部１２に、複数のボルト挿通孔が均等な間隔で穿設される。 In the bracket 9, a lower flange portion 12 having a diameter larger than that of the outer ring 6 is formed on the outer periphery of the lower portion, and a plurality of bolt insertion holes are formed in the lower flange portion 12 at equal intervals.
また、前記下部走行体３のフレームには、前記ボルト挿通孔と同一の中心軸を有した複数の雌ねじ孔が、前記ボルト挿通孔同様に均等な間隔で設けられる。ブラケット９とフレームとは、前記雌ねじ孔と下部フランジ部１２のボルト挿通孔との位置を合わせて、前記下部フランジ部１２側から連結ボルト１３を差込んで締結することによって連結され、これにより、上部旋回体２は旋回軸受４の内輪５と一体に、また、下部走行体３はブラケット９を介して旋回軸受４の外輪６と一体に連結される。 Further, a plurality of female screw holes having the same central axis as the bolt insertion holes are provided in the frame of the lower traveling body 3 at equal intervals like the bolt insertion holes. The bracket 9 and the frame are connected by aligning the positions of the female screw hole and the bolt insertion hole of the lower flange portion 12 and inserting and fastening the connecting bolt 13 from the lower flange portion 12 side. The upper swing body 2 is connected integrally with the inner ring 5 of the swing bearing 4, and the lower traveling body 3 is connected integrally with the outer ring 6 of the swing bearing 4 via a bracket 9.
このようにして、建設機械１を輸送する際には、下部走行体３のフレームと、ブラケット９の下部フランジ部１２とを連結している複数の連結ボルト１３を取外すことにより、上部旋回体２と下部走行体３とを分割することができる。 Thus, when transporting the construction machine 1, the upper swing body 2 is removed by removing the plurality of connecting bolts 13 that connect the frame of the lower traveling body 3 and the lower flange portion 12 of the bracket 9. And the lower traveling body 3 can be divided.
このとき、複数の連結ボルト１３は、大径の下部フランジ部１２の上方より下に向けて締結されているので、他の部材に接触することなく、簡単に連結ボルト１３を取外すことができ、効率よく上部旋回体２と下部走行体３とを分割することができる。 At this time, since the plurality of connecting bolts 13 are fastened downward from above the large-diameter lower flange portion 12, the connecting bolts 13 can be easily removed without contacting other members. The upper revolving unit 2 and the lower traveling unit 3 can be divided efficiently.
また、下部走行体３に上部旋回体２を組み付ける際には、下部走行体３のフレームとブラケット９の下部フランジ部１２とを連結ボルト１３で締結すれば簡単に組み付けることができる。 Further, when the upper swing body 2 is assembled to the lower traveling body 3, it can be easily assembled by fastening the frame of the lower traveling body 3 and the lower flange portion 12 of the bracket 9 with the connecting bolt 13.
このとき、連結ボルト１３は、自然とネジ穴へ位置させることができ、また、下部フランジ部１２のボルト挿通孔及びフレームの雌ねじ孔は、それぞれ均等な間隔で設けられているので、任意の方向で組み付けることができる。 At this time, the connecting bolt 13 can be naturally positioned in the screw hole, and the bolt insertion hole of the lower flange portion 12 and the female screw hole of the frame are provided at equal intervals, so any direction Can be assembled with.
さらに、下部フランジ部１２の径を大きく形成しているので、上部旋回体２の安定性を向上させることができ、従来、重心のバランスを取るために、フレームに台座等を取付ける場合があったが、特に台座等を取付けなくても上部旋回体２の安定性を確保することができる。 Furthermore, since the diameter of the lower flange portion 12 is formed to be large, the stability of the upper swing body 2 can be improved, and conventionally, a pedestal or the like may be attached to the frame in order to balance the center of gravity. However, the stability of the upper swing body 2 can be ensured without particularly mounting a pedestal or the like.
前記特許文献１の建設機械１は、上部旋回体２の安定性を向上させるためブラケット９の下部フランジ部１２の径を大きく形成している。 In the construction machine 1 of Patent Document 1, the diameter of the lower flange portion 12 of the bracket 9 is formed large in order to improve the stability of the upper swing body 2.
このようなブラケットを挿入する為、従来下部走行体に突設していたブラケットを取外したものである。また、両端のフランジ部は、旋回軸受側のボルト挿通孔は、旋回軸受の雌ネジ孔のピッチ円直径等と同一と考えられるが、下部走行体側のボルト挿通孔は、下部走行体側に新たに設けた雌ネジ孔のピッチ円直径等と同様と思われる。 In order to insert such a bracket, the bracket that has conventionally been projected from the lower traveling body is removed. In addition, it is considered that the bolt insertion hole on the slewing bearing side is the same as the pitch circle diameter of the female screw hole of the slewing bearing, but the bolt insertion hole on the lower traveling body side is newly provided on the lower traveling body side. It seems to be the same as the pitch circle diameter of the female screw hole provided.
このような方法は、下部走行体に対して切断やタッピング等の機械加工を行う必要があり、面倒で、費用もかさむ。 Such a method requires machining such as cutting and tapping on the lower traveling body, which is cumbersome and expensive.
本発明の目的は前記従来例の不都合を解消し、ブラケットを挿入する為にボルト頭部を機械外側となる位置関係にさせることで分割する為のボルト脱着作業を容易に行うことができるとともに、下部走行体に対して切断やタッピング等の機械加工を行う必要がないので面倒な手間がなく、安価に実現できる分解型建設機械を提供することにある。 The object of the present invention is to eliminate the inconvenience of the conventional example, and to easily perform the bolt detachment work for dividing by making the bolt head into a positional relationship that is the outside of the machine in order to insert the bracket, An object of the present invention is to provide a disassembly type construction machine that can be realized at low cost without troublesome work because it is not necessary to perform machining such as cutting and tapping on the lower traveling body.
前記目的を達成するため請求項１記載の本発明は、下部走行体の上部に上部旋回体を旋回輪を介して旋回可能に設けた建設機械において、上部旋回体の旋回輪と下部走行体のフランジ間にブラケットを挿入するもので、該ブラケットは同一径の上下フランジを有する円筒体であり、旋回輪側の上フランジには、下部走行体の設置面に設けられているフランジ部の雌ネジ孔と同一の雌ネジ孔を設け、ブラケットの下部走行体側の下フランジに前記旋回輪に設けられているボルト挿通孔のそれらとピッチ円直径や間隔及び孔径が同一のボルト挿通孔を設けたことを要旨とするものである。 The present invention of claim 1, wherein in order to achieve the above object, a construction machine which is provided pivotably via a pivoting wheels upper rotating body on the lower traveling body, the upper rotating body slewing ring and the lower traveling body A bracket is inserted between the flanges , and the bracket is a cylindrical body having upper and lower flanges of the same diameter. The upper flange on the swivel wheel side has a female screw in the flange portion provided on the installation surface of the lower traveling body. The same female screw hole as that of the hole is provided, and the bolt insertion hole having the same pitch circle diameter, spacing and hole diameter as those of the bolt insertion hole provided in the swivel wheel is provided in the lower flange on the lower traveling body side of the bracket. Is a summary.
請求項１記載の本発明によれば、ブラケットは、旋回軸受と下部走行体の間に挿入されるものとして構成し、形状は、両端にフランジ部を持つ円筒体である。 According to the first aspect of the present invention, the bracket is configured to be inserted between the swivel bearing and the lower traveling body, and the shape is a cylindrical body having flange portions at both ends.
分割箇所の連結ボルトの頭部は、従来の状態では機械外側から見えない箇所にあるので、分割する為のボルト脱着作業が困難であったが、本発明はフランジ部を持つ円筒体を挿入することで、ボルト頭部を機械外側となる位置関係にさせることで分割する為のボルト脱着作業を容易に行うことができる。 In the conventional state, the head of the connecting bolt at the divided portion is invisible from the outside of the machine. Therefore, it is difficult to remove and attach the bolt for dividing, but the present invention inserts a cylindrical body having a flange portion. Thus, the bolt removing operation for dividing the bolt head can be easily performed by bringing the bolt head into the positional relationship on the outside of the machine.
請求項１記載の本発明によれば、旋回軸受側のフランジは雌ネジ孔が設けられている。この雌ネジ孔のピッチ円直径や間隔及びネジ径は、トラックフレーム（下部走行体）の、旋回軸受と連結する設置面に設けられている雌ネジ孔のそれらと同一である。 According to the first aspect of the present invention, the flange on the slewing bearing side is provided with the female screw hole. The pitch diameter, interval, and screw diameter of the female screw holes are the same as those of the female screw holes provided on the installation surface of the track frame (lower traveling body) connected to the swivel bearing.
下部走行体側のフランジはボルト挿通孔が設けられている。このボルト挿通孔のピッチ円直径や間隔及び孔径は、旋回軸受の、下部走行体と連結する旋回輪に設けられているボルト挿通孔のそれらと同一である。 The flange on the lower traveling body side is provided with a bolt insertion hole. The pitch circle diameter, the interval, and the hole diameter of the bolt insertion holes are the same as those of the bolt insertion holes provided in the swivel wheel of the slewing bearing connected to the lower traveling body.
このようにフランジ部に設ける雌ネジ孔及びボルト挿通孔は、従来の下部走行体及び旋回軸受に設けられているそれの寸法を使用したので、ブラケットを挿入する為に、従来の構造物に機械加工を必要としない。 Since the female screw hole and the bolt insertion hole provided in the flange portion in this manner use the dimensions of those provided in the conventional lower traveling body and the swivel bearing, in order to insert the bracket, No processing is required.
さらに、円筒体ブラケットの取付位置は、吊り作業時に上部旋回体を吊る為の吊り具の固定位置から見て、上部旋回体の重心よりも低い位置にある為、重心を下げる効果が得られ、吊り作業時の安定性を向上させる事が出来る。 Furthermore, since the mounting position of the cylindrical bracket is at a position lower than the center of gravity of the upper swing body as seen from the fixing position of the lifting tool for hanging the upper swing body during the suspension work, the effect of lowering the center of gravity can be obtained, Stability during hanging work can be improved.
請求項２記載の本発明は、下フランジの外径は下部走行体の設置面の外径以上に形成し、下フランジの内径は、円筒体ブラケットの内径と同一としたことを要旨とするものである。 The gist of the present invention described in claim 2 is that the outer diameter of the lower flange is greater than the outer diameter of the installation surface of the lower traveling body, and the inner diameter of the lower flange is the same as the inner diameter of the cylindrical bracket. It is.
請求項２記載の本発明によれば、円筒体ブラケットの外径は、下部走行体と円筒体ブラケットを接続するボルトの取付に干渉しないように、下部走行体の設置面の内径よりも小さく形成される為、下フランジの内径はこれよりも小さく形成される。これにより下フランジのフランジ面は、下部走行体の設置面よりも大きい面積を有する為、平面への設置時に対して、安定性を向上させる事が出来る。 According to the second aspect of the present invention, the outer diameter of the cylindrical bracket is formed smaller than the inner diameter of the installation surface of the lower traveling body so as not to interfere with the mounting of the bolt that connects the lower traveling body and the cylindrical bracket. Therefore, the inner diameter of the lower flange is formed smaller than this. Thereby, since the flange surface of a lower flange has a larger area than the installation surface of a lower traveling body, stability can be improved with respect to the time of installation to a plane.
以上述べたように本発明の分解型建設機械は、ブラケットを挿入する為にボルト頭部を機械外側となる位置関係にさせることで分割する為のボルト脱着作業を容易に行うことができるとともに、従来の構造物に機械加工を必要としないので面倒な手間がなく、安価に実現できるものである。 As described above, the disassembly type construction machine of the present invention can easily perform the bolt removing operation for dividing by making the bolt head into a positional relationship that is the outside of the machine in order to insert the bracket, Since the conventional structure does not require machining, there is no troublesome work and it can be realized at low cost.
以下、図面について本発明の実施の形態を詳細に説明する。図１は本発明の分解型建設機械の全体を示す側面図、図２は同上説明図で、前記従来例を示す図１０と同一構成要素には同一参照符号を付したものである。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an entire disassembled construction machine according to the present invention, and FIG. 2 is an explanatory view of the same. In FIG. 1, the same components as those in FIG.
図９示すように本発明の分解型建設機械も下部走行体３の上部に、上部旋回体２を旋回輪１４（前記図９、図１０の旋回軸受４に相当）を介して旋回可能に設けたものである。 As shown in FIG. 9, the disassembly type construction machine of the present invention is also provided on the upper part of the lower traveling body 3 so that the upper swing body 2 can be swung via a swivel wheel 14 (corresponding to the swivel bearing 4 in FIGS. 9 and 10). It is a thing.
上部旋回体２と下部走行体３との間の旋回輪１４を介して、下部走行体３の上部に上部旋回体２が旋回可能に配設されている。 The upper swing body 2 is turnably disposed on the upper portion of the lower traveling body 3 via a swirl wheel 14 between the upper swing body 2 and the lower traveling body 3.
下部走行体３は、前記旋回輪１４に向けて、複数の連結ボルトが挿通され、締結されることによって、下部走行体３と旋回輪１４とが連結されるフランジ部１５を有し、前記上部旋回体２の旋回輪１４の外輪に向けて、複数の連結ボルトが挿通され、締結されることによって、下部走行体３と旋回輪１４とが連結される。 Undercarriage 3, toward the slewing ring 14, a plurality of connecting bolts are inserted, by being fastened, a flange portion 15 where the lower traveling body 3 and the turning wheels 14 are connected, the upper A plurality of connecting bolts are inserted and fastened toward the outer ring of the turning wheel 14 of the turning body 2, whereby the lower traveling body 3 and the turning wheel 14 are connected.
図９にも示すように、本発明は、上部旋回体２の旋回輪１４と下部走行体３のフランジ部１５との間にブラケット１６を挿入するもので、該ブラケット１６はリング体本体の上下に同一外周径の上下フランジ１７，１８を設けた円筒体であり、旋回輪１４側の上フランジ１７には、下部走行体３の前記旋回輪１４と連結する設置面に設けられているフランジ部１５の雌ネジ孔と同一の雌ネジ孔１９を設けた。 As shown in FIG. 9, the present invention inserts a bracket 16 between the turning wheel 14 of the upper turning body 2 and the flange portion 15 of the lower traveling body 3. Are provided with upper and lower flanges 17 and 18 having the same outer diameter, and the upper flange 17 on the side of the turning wheel 14 is provided with a flange portion provided on an installation surface connected to the turning wheel 14 of the lower traveling body 3. The same female screw hole 19 as the 15 female screw holes was provided.
また、ブラケット１６の下部走行体３側の下フランジ１８には下部走行体３のフランジ部１５と連結する旋回輪１４に設けられているボルト挿通孔のそれらとピッチ円直径や間隔及び孔径が同一のボルト挿通孔３０を設けた。 Also, the lower flange 18 on the lower traveling body 3 side of the bracket 16 has the same pitch circle diameter, spacing and hole diameter as those of the bolt insertion holes provided in the turning wheel 14 connected to the flange portion 15 of the lower traveling body 3. Bolt insertion hole 30 was provided.
前記円筒体ブラケット１６の下フランジ１８は、下部走行体３の旋回輸１４と連結する設置面に設けられている雌ネジ孔のピッチ円直径や間隔を同一にし、また、接触面積を通常の建設機械と同等に確保する為、下フランジ１８の外径は下部走行体３の設置面の外径以上に形成した。 The lower flange 18 of the cylindrical bracket 16 has the same pitch circle diameter and interval of the female screw holes provided on the installation surface connected to the swivel transport 14 of the lower traveling body 3, and has a contact area of normal construction. In order to ensure the same level as the machine, the outer diameter of the lower flange 18 was formed to be greater than the outer diameter of the installation surface of the lower traveling body 3.
一方、下フランジ１８の内径は、円筒体ブラケット１６の内径と同一となるが、円筒体ブラケット１６の外径は、下部走行体３と円筒体ブラケットを接続するボルトの取付に干渉しないように、下部走行体３の設置面の内径よりも小さく形成される為、下フランジ１８の内径はこれよりも小さく形成される。 On the other hand, the inner diameter of the lower flange 18 is the same as the inner diameter of the cylindrical bracket 16, but the outer diameter of the cylindrical bracket 16 does not interfere with the mounting of the bolt that connects the lower traveling body 3 and the cylindrical bracket. Since it is formed smaller than the inner diameter of the installation surface of the lower traveling body 3, the inner diameter of the lower flange 18 is formed smaller than this.
すなわち、図９に示すように、下部走行体３のフランジ部１５の幅αよりも下フランジ１８の幅βを広くなるように設定する。 That is, as shown in FIG. 9, the width β of the lower flange 18 is set to be wider than the width α of the flange portion 15 of the lower traveling body 3.
なお、ブラケット１６のリング体本体は、上下フランジ１７，１８及びその間に挿入され、このリング体本体の外側に設けたリブ３１により強度を確保している。 The ring body main body of the bracket 16 is inserted between the upper and lower flanges 17 and 18 and the ribs 31 provided outside the ring body main body to ensure strength.
次に使用法について説明する。図９に示すように建設機械１は下部走行体３の上部に、上部旋回体２が旋回輪１４を介して旋回可能に設けられている。 Next, the usage will be described. As shown in FIG. 9, the construction machine 1 is provided with an upper swing body 2 on the upper portion of the lower traveling body 3 so that the upper swing body 2 can be turned via a turning wheel 14.
この状態では、分割箇所の連結ボルトの頭部は、従来の状態では機械外側から見えない箇所にある。その為分割する為のボルト脱着作業が困難である。 In this state, the heads of the connecting bolts at the divided locations are in a location that cannot be seen from the outside of the machine in the conventional state. Therefore, it is difficult to remove and install the bolts for dividing.
上部旋回体２の旋回輪１４と下部走行体３のフランジ部１５との間にブラケット１６を挿入する。 A bracket 16 is inserted between the turning wheel 14 of the upper turning body 2 and the flange portion 15 of the lower traveling body 3.
ブラケット１６の上フランジ１７を旋回輪１４に合わせ、旋回輪１４に設けられているボルト挿通孔と上フランジ１７の雌ネジ孔１９をボルトで締結する。 The upper flange 17 of the bracket 16 is aligned with the turning wheel 14, and the bolt insertion hole provided in the turning wheel 14 and the female screw hole 19 of the upper flange 17 are fastened with bolts.
また、ブラケット１６の下フランジ１８を下部走行体３のフランジ部１５に合わせ、下フランジ１８に設けられているボルト挿通孔と下フランジ１８に設けられているボルト挿通孔３０をボルトで締結する。 Further, the lower flange 18 of the bracket 16 is aligned with the flange portion 15 of the lower traveling body 3, and the bolt insertion hole provided in the lower flange 18 and the bolt insertion hole 30 provided in the lower flange 18 are fastened with bolts.
