従来から建設機械、特にパワ−ショベル等の作業機において、ブ−ムを上部旋 回体に取付ける場合、作業機取付用の基部とブ−ムの基端との間にピンを挿入し て、ブ−ムを旋回体に対して回動させるようにしている。その具体的な詳細構造 は、図７に示すように左右に離設して一体に形成された基部となる第１部材２１ ａと、２１ｂとの間にブッシュ２３を内嵌したブ−ム等の第２部材２２を挿入し て連結するものであり、第１部材２１ｂの軸方向に穿設された孔には、端部にシ −ル２４が収納されるカウンタボア２６を有するカラ−２５と、カラ−２５と一 体に溶着されたピン２７が嵌入されている。ピン２７の端部には回り止め用の穴 ２８を有するねじ２９が設けられている。該カラ−２５のカウンタボア２６には シ−ル２４が装着され、カラ−２５とブッシュ２３との間の軸部にはスペ−サリ ング３０が配設されている。第１部材１ａ側からはスペ−サリング３０、および カウンタボア２６にシ−ル２４を装着したカラ−３１が嵌入され、ピン２７の端 部はナット３２により締結され、ピン２７とカラ−３２との間にはＯリング３３ が装着されている。前記ナット３２には半径方向に複数個の穴３３が穿設され、 ナット３２を装着したのち、回り止めのスプリング３４で回り止めするようにな っている。そしてピン２７はカラ−２５および３２を介して第１部材２１ａ，２ １ｂに対してそれぞれ回転方向を拘束されており、第２部材２２のブッシュ２３ はピン２７に対して回動自在となっている。図中、３５はオイル溜め、３６は潤 滑油供給用の孔である。 Conventionally, in construction machines, especially work machines such as power shovels, the boom is rotated upward. When mounting on the revolving body, insert a pin between the base for mounting the work implement and the base end of the boom. The boom is rotated with respect to the revolving structure. Its concrete detailed structure Is a first member 21 which is a base integrally formed by being separated left and right as shown in FIG. Insert a second member 22 such as a boom in which a bush 23 is fitted between a and 21b. The hole formed in the axial direction of the first member 21b has a seal at the end. A color 25 having a counterbore 26 in which the ruler 24 is stored; The pin 27 welded to the body is inserted. A hole for preventing rotation at the end of the pin 27 A screw 29 having 28 is provided. In the counter bore 26 of the color 25, A seal 24 is mounted, and a spacer is provided on the shaft between the collar 25 and the bush 23. A ring 30 is provided. From the first member 1a side, the spacer ring 30, and A collar 31 with a seal 24 attached is fitted into the counter bore 26, and the end of the pin 27 is inserted. The part is fastened with a nut 32, and an O-ring 33 is provided between the pin 27 and the collar 32. Is installed. A plurality of holes 33 are formed in the nut 32 in the radial direction, After mounting the nut 32, make sure to use the detent spring 34 to detent it. ing. Then, the pin 27 is connected to the first members 21a, 2 through the collars 25 and 32. The rotation direction is restrained with respect to 1b, respectively, and the bush 23 of the second member 22 is Is rotatable with respect to the pin 27. In the figure, 35 is an oil reservoir and 36 is a moisturizer. It is a hole for supplying lubricating oil.

しかしながらこの場合例えば、図８に示すように、下部走行体４１の上に、設 けられた上部旋回体４２には作業機取付用の基部４３とキャビン４４が並列に配 置されている関係上、キャビン４４との間隔Ｌ（図８の実施例では約６０ｍｍ程 度）が少ないために、ピン２７は図の右側からは挿入できず、したがって左側（ 図７と図８は軸挿入方向が逆となっている）からのみ挿入できる構造となってい る。ところがピン２７を支える両側の支持部にはそれぞれ図７で示した鍔付きの カラ−２５，３１を第１部材（基部４３）の外側から挿入するようになっており 、左側からの挿入は問題はないが、右側からは図８のように間隔が少ないため挿 入出来ないと云う問題がある。そこで、ブ−ムの組立の場合はキャビンを取付け る前にカラ−３２を右から挿入することも考えられるが、メンテナンスの場合に はどうしても、キャビン４４を取り外さなければならず、極めて大掛かりになる 等問題であった。 However, in this case, for example, as shown in FIG. The upper revolving structure 42 thus mounted has a base 43 for mounting a working machine and a cabin 44 arranged in parallel. Due to the fact that it is placed, the distance L to the cabin 44 (about 60 mm in the embodiment of FIG. 8) Pin 27 cannot be inserted from the right side of the figure, and therefore the left side ( (Figs. 7 and 8 have opposite shaft insertion directions.) It However, the support portions on both sides that support the pins 27 have the collars shown in FIG. 7, respectively. The collars 25 and 31 are designed to be inserted from the outside of the first member (base 43). , Inserting from the left side is not a problem, but inserting from the right side is small as shown in Fig. 8. There is a problem that you can not enter. Therefore, when assembling the boom, attach the cabin. It is possible to insert the color 32 from the right before Inevitably, the cabin 44 must be removed, which is extremely large. It was a problem.
【０００４】 本考案はこれに鑑み、ブ−ムと旋回体の組立および分解をキャビンを取外すこ となく行えるようにした作業機連結装置を提供して状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。[0004] In view of this, the present invention is to remove the cabin when assembling and disassembling the boom and the swing body. Providing a work equipment connecting device that can be done without problems to eliminate the drawbacks of conventional technology It was made for the purpose of achieving it.

An O-relief is provided between the first collar-3 and the pin 7. 18 is provided to prevent the oil lubricated during this from leaking to the outside. It is like this. In the figure, 19 is a tap.
【００１０】 つぎに作用（組み立ての手順）を説明する。まず、 第１カラ−３を第１部材 １ａの孔２ａに内側から嵌装し，ストッパ８に当たるまで押し込む。第１カラ− ３の切り欠き３ｂがストツパ８とほぼ合致すると、回り止めされてその位置が規 制される。つぎに、 ブッシュ６、およびシ−ル１７を装着した第２部材５を第 １部材１ａ、１ｂ間に嵌合し、第１部材１ａ，１ｂと第２部材５の軸芯をほぼ合 わせる。 スペ−サリング１６を装着したピン７（第２カラ−４を含む）を第１ 部材１ｂ側より挿入してピン７と一体の第２カラ−４を回り止めプレ−ト１４を 介して締結手段１５により締め付けピン７を固定する。 ピン７のねじ７ａに弛 み止めナット１３を締め付け、ピン７上の左右隙間がゼロになるまで均等に締め る。左右隙間がゼロになった点（トルク管理）より約４０°ほど弛み止めナット １３を弛める。これによりエンドプレ−は０〜０．２５ｍｍに管理される。[0010] Next, the operation (assembly procedure) will be described. First, the first color-3 is the first member It is fitted from the inside into the hole 2a of 1a and pushed in until it hits the stopper 8. First color When the notch 3b of 3 substantially coincides with the stopper 8, it is prevented from rotating and its position is regulated. Controlled. Next, the second member 5 with the bush 6 and the seal 17 attached is The first members 1a, 1b and the second member 5 are fitted to each other by fitting the shafts of the first member 1a, 1b. Tell First set the pin 7 (including the second collar-4) with the spacer ring 16 attached. Insert the second collar 4 integrally with the pin 7 by inserting it from the member 1b side to prevent the plate 14 from rotating. The fastening pin 7 is fixed by the fastening means 15 through. Loosen the screw 7a of the pin 7 Tighten the lock nut 13, and evenly tighten until the clearance on the left and right on the pin 7 becomes zero. It An anti-loosening nut about 40 ° from the point where the left-right gap becomes zero (torque management) Loosen 13. As a result, the end play is controlled to 0 to 0.25 mm.
【００１１】 つぎに、分解時の手順を説明する。ピン７を取り外す場合は、図４および図５ に示すように、まず、 弛み止めナット１２を弛め、これをピン７から取り外す 。 治具１０を第１カラ−３の溝９に係合したのち、抜きボルト２０を治具１０ に設けられたねじ孔にねじ込むと、第１カラ−３はストッパ８に接触するまで外 側に移動し、鍔３ａとピン７の端部との接触がなくなる。そこでピン７を抜き、 第１部材１ａ，１ｂからブ−ムである第２部材５を取り外す。 治具１０を外し 、第１カラ−３を第１部材１ａの内側に抜くことにより分解が完了する。[0011] Next, the procedure for disassembly will be described. 4 and 5 when removing the pin 7. First, loosen the lock nut 12 and remove it from the pin 7 as shown in . After engaging the jig 10 with the groove 9 of the first collar 3, the removal bolt 20 is attached to the jig 10. When screwed into the screw hole provided in the It moves to the side and the contact between the flange 3a and the end of the pin 7 is lost. So pull out pin 7, The second member 5, which is a boom, is removed from the first members 1a and 1b. Remove the jig 10 The disassembly is completed by pulling out the first collar 3 inside the first member 1a.
【００１２】 図６は図１のスペ−サリングを用いず、シ−ル１７をブッシュ６′上に設けた 第２実施例を示し、その他の部品は第１実施例の図１と全く同一であり、したが って説明は省略するが、効果も第１実施例と同一である。なお、本考案は実施例 において、キャビンに接近した上部旋回体のブ−ム取付部にブ−ムの基部をピン により取付ける場合を説明したが、ブ−ムの場合に限定するものではなく、他側 が狭くて一側からのみ取付けが可能な場合の連結装置に適用できることは云うま でもない。[0012] In FIG. 6, a seal 17 is provided on the bush 6'without using the spacer of FIG. The second embodiment is shown, and the other parts are exactly the same as those in FIG. 1 of the first embodiment. Although the description is omitted, the effect is the same as that of the first embodiment. The present invention is an embodiment , Pin the boom base to the boom mounting part of the upper swing structure near the cabin. Although the case of mounting with the other side has been explained, it is not limited to the case of the boom Needless to say, the present invention can be applied to a connecting device in the case where the space is narrow and mounting is possible only from one side. not.
