本考案の実施例を図面に基づいて説明する。 図中1は上記した建設機械、例えばブルドーザの履帯走行装置に用いられる乾 地用の履板であり、この履板1はそれぞれリンク2にて無端状に連結されて履帯 を構成するようになっている。そして上記履板1の踏面の幅方向の一側部に滑り 止めの突条3が長手方向全長にわたって設けられている。 An embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a track plate for dry land used in the above-mentioned construction machine, for example, a track running device of a bulldozer. The track plates 1 are endlessly connected by links 2 to form a track. ing. A non-slip ridge 3 is provided on one side of the tread surface of the crawler plate 1 in the width direction over the entire length in the longitudinal direction.
【0008】 4は上記履帯を構成する各履板1の踏面側に着脱可能に固着される履帯用パッ ドであり、この履帯用パッド4は踏面を構成する弾性部材5と、この弾性部材5 を補強する芯金6と、この芯金6の一端部に一体状に設けられた固着鉤部材7と 、他端部に着脱可能に固着される着脱鉤部材8とからなっている。この着脱鉤部 材8の取付けは芯金6に固着したナット部材9に螺合するボルト10にて固着す る。なお上記ナット部材9をボルト部材にしてこれを着脱鉤部材8に貫通させ、 これにナット部材を螺合することにより着脱鉤部材8を固着するようにしてもよ い。またこの着脱鉤部材8の取付け部8aは履板1の端部に係合する鉤部8bよ り内側へ折れ曲がっており、ボルト10の頭部が鉤部8bより突出しないように なっている。Reference numeral 4 denotes a crawler belt pad that is detachably fixed to the tread surface side of each crawler plate 1 that constitutes the crawler belt. The crawler belt pad 4 includes an elastic member 5 that constitutes the tread surface, and this elastic member 5. The core metal 6 for reinforcing the core metal 6, a fixing hook member 7 integrally provided at one end of the core metal 6, and a detachable hook member 8 detachably fixed to the other end. The attachment / detachment hook member 8 is fixed by a bolt 10 screwed to a nut member 9 fixed to the core metal 6. Alternatively, the nut member 9 may be used as a bolt member to penetrate the detachable hook member 8 and the nut member may be screwed into the detachable hook member 8 to fix the detachable hook member 8. The attaching portion 8a of the detachable hook member 8 is bent inward from the hook portion 8b that engages with the end of the shoe plate 1, so that the head of the bolt 10 does not protrude from the hook portion 8b.
【0009】 上記芯金6は板状になっていて、その幅方向略中央部に補強用のリブ11が略 全長にわたって設けられている。なおこのリブ11は履板1とリンク2とを結合 するリンク取付けボルト12の頭部をかわす位置に設けられている。そしてこの リブ11が履板1の踏面に当接して当接脚部の役目をなしている。The cored bar 6 has a plate-like shape, and a reinforcing rib 11 is provided at substantially the center in the width direction over substantially the entire length. The ribs 11 are provided at positions where the heads of the link mounting bolts 12 for connecting the track plate 1 and the links 2 are avoided. The ribs 11 are in contact with the tread surface of the shoe plate 1 and serve as contact legs.
【0010】 上記のように構成された履帯用パッド4と履板1との結合は、主として、履帯 用パッド4の長手方向両側部の固着鉤部材7と着脱鉤部材8にて行なわれるが、 これだけでは結合強度的に不十分なので、芯金6を履板1側に係合する手段がと られる。 すなわち図1から図3に示すように、履板1の突条3の長手方向中間部に切欠 き13を設け、一方芯金6にはこの突条3の切欠き13に係合する鉤部片14を 設け、この両者が履帯用パッド4の取付け状態で係合するようになっている。The coupling of the crawler belt pad 4 and the crawler plate 1 configured as described above is mainly performed by the fixed hook members 7 and the detachable hook members 8 on both sides in the longitudinal direction of the crawler belt pad 4, Since this alone is insufficient in terms of bonding strength, means for engaging the cored bar 6 with the track plate 1 side is taken. That is, as shown in FIGS. 1 to 3, a notch 13 is provided at an intermediate portion in the longitudinal direction of the ridge 3 of the shoe plate 1, and a hook portion that engages with the notch 13 of the ridge 3 is provided on the core metal 6. A piece 14 is provided, and both are engaged with each other when the crawler belt pad 4 is attached.
【0011】 図4、図5は上記芯材6と履板1との係合手段の他側を示すもので、履板1の 突条3にボルト穴15を設け、一方芯金6にこの突条3のボルト穴15に対応す る位置にナット部材6aを固着し、履帯用パッド4の取付け状態でボルト穴15 にボルト16を貫通させてナット部材6aに螺合するようになっている。FIGS. 4 and 5 show the other side of the engaging means between the core material 6 and the shoe plate 1, where the projecting ridges 3 of the shoe plate 1 are provided with bolt holes 15 and the core metal 6 is provided with the bolt holes 15. A nut member 6a is fixed at a position corresponding to the bolt hole 15 of the ridge 3, and when the track pad 4 is attached, a bolt 16 is passed through the bolt hole 15 and screwed into the nut member 6a. .
【0012】 図6、図7(a)、(b)はさらに他例を示すもので、履板1の長手方向両端 部に固着鉤部材7及び着脱鉤部材8の取付け部8aが係合する切欠き17,17 を設ける。このとき、履板1の長手方向両側端部の裏面にも図7(a)、(b) に示すように各鉤部材7,8の下側鉤片8bが係合する凹部18,18を設けて もよい。 この実施例によれば、履板用パッド4の構成はこれの芯金6の全長を上記両切 欠き17,17の切欠き深さ分だけ短くする。なおこの実施例では、各鉤部材7 ,8の係合部が履板1の切欠き17,17に係合するため、鉤部材7,8の外端 面が履板1の外側面と一致することになり、その突出量をゼロにすることができ る。またこの実施例はパワーショベル用の履板等のように、突条3が特にないよ うな履板の場合に用いられる。FIGS. 6, 7 (a) and 7 (b) show another example, in which the fixing hook members 7 and the attachment portions 8 a of the detachable hook members 8 are engaged with both longitudinal ends of the shoe plate 1. Notches 17 and 17 are provided. At this time, recesses 18 and 18 with which the lower hook pieces 8b of the hook members 7 and 8 are engaged are also formed on the back surfaces of the longitudinal end portions of the track plate 1 as shown in FIGS. 7 (a) and 7 (b). May be provided. According to this embodiment, the structure of the track pad 4 is such that the total length of the core bar 6 thereof is shortened by the depth of the notches 17 and 17. In this embodiment, since the engaging portions of the hook members 7 and 8 engage with the notches 17 and 17 of the shoe plate 1, the outer end surfaces of the hook members 7 and 8 are aligned with the outer surface of the shoe plate 1. Therefore, the amount of protrusion can be reduced to zero. Further, this embodiment is used in the case of a shoe plate such as a shoe plate for a power shovel which does not have the protrusion 3 in particular.
【0013】 図8はさらに他の実施例を示すもので、履板1の踏面部に複数個のボルト貫通 穴19を設け、これを貫通するボルト20にて履帯用パッド4を履板1に結合す る。FIG. 8 shows still another embodiment. A plurality of bolt through holes 19 are provided in the tread surface of the track plate 1, and the track pads 4 are attached to the track plate 1 by bolts 20 penetrating the bolt through holes 19. Join.
