Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は無限軌道帯車輛、特に土木建築用または荷役
用の無限軌道帯を具えた自走機械に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a crawler belt vehicle, and more particularly to a self-propelled machine having a crawler belt for civil engineering or cargo handling.
土木建築用や荷役用の自走機械に、鋼製の無限軌道帯が
広く使用されているが、舗装道路上を走行すると、路面
を著しく損傷する、これを防ぐために、履板にゴムブロ
ックを取付けた無限軌道帯が、実公昭50−27071号公報
や実公昭48−43537号公報に示されている。Steel tracked tracks are widely used in self-propelled machinery for civil engineering and loading and unloading, but when running on a paved road, the track surface is significantly damaged.To prevent this, rubber blocks are attached to the track. The installed endless orbital belt is shown in JP-B-50-27071 and JP-B-48-43537.
上述の実用新案公報に示されている無限軌道帯のゴムブ
ロックは、接地面が平坦である。ところが、無限軌道帯
車輛の走行中の方向転換は、曲ろうとする側の無限軌道
帯を制動または逆転することによって行なわれるため
に、接地面が平坦で路面との摩擦が小さい場合には、確
実な方向転換が困難である。The endless track rubber block shown in the above-mentioned utility model publication has a flat grounding surface. However, since the direction change during running of a crawler belt vehicle is performed by braking or reversing the crawler belt on the side that is about to bend, if the contact surface is flat and the friction with the road surface is small, it is possible to It is difficult to change direction.
これに加え、このゴムブロックは接地部分が頻繁に破損
したり激しく摩耗したりして、命数が非常に短いため
に、頻繁に交換する必要があるが、そのために多額の経
費が必要である。In addition to this, the rubber block has a very short life due to frequent breakage or severe wear of the grounding part, which requires frequent replacement, which requires a large amount of expense.
この考案は、舗装路面を損傷せず、車輛の方向転換を確
実に行なうことができ、かつ長期にわたって使用できる
無限軌道帯を実現しようとするものである。This invention is intended to realize an endless track zone that can reliably change the direction of a vehicle without damaging a pavement surface and can be used for a long period of time.
この考案の履板は、無限軌道帯の伸延方向と交叉する方
向の樋状の凹所を表面に有し、この凹所には、この凹所
の幅にほぼ等しい外径のゴム筒がその一部を突出させて
収容されている。このゴム筒は、その中心を貫通する補
強芯によって補強されており、この補強芯の上記ゴム筒
両端から突出する部分は角柱状をなしている。The shoe plate of the present invention has a trough-shaped recess on the surface in a direction intersecting with the extension direction of the endless track, and in this recess, a rubber tube having an outer diameter substantially equal to the width of the recess is formed. It is housed with part of it protruding. The rubber cylinder is reinforced by a reinforcing core penetrating its center, and the portions of the reinforcing core protruding from both ends of the rubber cylinder are prismatic.
上記凹所には、対をなす支持体がほぼ上記ゴム筒の長さ
に等しい距離に隔てて設けられており、その一方の支持
体は門型をなし、他方の支持体は外方向へ向う切欠きを
有する。上記補強芯の一方の突出部は上記門型支持体に
挿通され、他方の突出部は上記切欠き内に挿入される。
そして、上記切欠きに挿入された突出部にはＵボルトが
かけられ、このＵボルトは履板を貫通してその裏面にお
いてナットで緊締されている。A pair of supports is provided in the recess at a distance substantially equal to the length of the rubber cylinder, one support of which is a gate type, and the other support faces outward. Has a notch. One protrusion of the reinforcing core is inserted into the gate-shaped support, and the other protrusion is inserted into the notch.
Then, a U bolt is applied to the protruding portion inserted into the notch, and the U bolt penetrates the shoe plate and is tightened with a nut on the back surface thereof.
上述のように、履板裏面の樋状凹所に嵌込まれたゴム筒
は、補強芯の一端が門型支持体によって抑えられ、他端
がＵボルトによって抑えられているために、脱落しな
い。そして、補強芯の一端の角柱状突出部は門型支持体
に係合し、他端の角柱状突出部は支持体の切欠きに係合
しているために、ゴム筒はみだりに回転しない。As described above, the rubber cylinder fitted in the gutter-shaped recess on the back surface of the shoe plate does not fall off because one end of the reinforcing core is held by the gate-shaped support and the other end is held by the U-bolt. . Since the prismatic protrusion on one end of the reinforcing core engages with the gate-shaped support and the prismatic protrusion on the other end engages with the notch in the support, the rubber cylinder does not rotate excessively.
この状態で車輛が舗装路面を走行する際は、ゴム筒のみ
が接地するために、路面を損傷しない。また、このゴム
筒は従来の鋼製履板の突条と同様に、無限軌道帯の運動
時における路面との摩擦を高める方向に取付けられてい
るため、車輛の方向転換を円滑に行なうことができる。In this state, when the vehicle travels on the paved road surface, only the rubber tube is in contact with the ground so that the road surface is not damaged. Also, this rubber cylinder is mounted in a direction that enhances friction with the road surface during the movement of the endless track, similar to the conventional ridges of steel track plates, so that it is possible to smoothly change the direction of the vehicle. it can.
使用によってゴム筒の常時接地する部分が摩耗或いは損
傷した場合は、Ｕボルトを外すことによって、ゴム筒を
履板から取外すことができる。従って、ゴム筒を回転し
て、新しい部分が突出するように取付け直すことによ
り、再びこれを使用することができる。このように、ゴ
ム筒の接地部分を次々に変更して使用することができる
ため、その全周が摩耗または損傷するまで使用すること
ができ、その命数が極めて長い。When the always grounded portion of the rubber cylinder is worn or damaged by use, the rubber cylinder can be removed from the shoe plate by removing the U bolt. Therefore, it can be used again by rotating the rubber tube and reattaching it so that the new portion projects. As described above, since the grounded portion of the rubber cylinder can be changed and used one after another, it can be used until its entire circumference is worn or damaged, and its life is extremely long.

が極めて長い長所を有している。As is apparent from the above embodiments, according to the present invention, since the steel shoe plate does not directly contact the road surface, it is possible to prevent the paved road surface from being damaged. And, since the rubber cylinder provided in the direction traversing the endless track is configured to come into line contact with the road surface, the friction with the road surface during vehicle traveling is large,
The direction can be changed smoothly. Further, this rubber cylinder has an advantage that the life thereof is extremely long because it can be used in the opposite way by changing the ground contact portion.
