Description

本発明は、クローラ及び建設機械に関し、詳しくは、複数のクローラシューを無端状に連結するとともに、前記クローラシューの外面にゴムパッドを着脱可能に装着した大型建設機械に適したクローラ及びこのクローラを履いた建設機械に関する。   More particularly, the present invention relates to a crawler suitable for a large construction machine in which a plurality of crawler shoes are connected endlessly and a rubber pad is detachably attached to the outer surface of the crawler shoe. Related to construction machinery.

各種建設機械に用いられている金属製のクローラは、一般的に、前後両端に配置されたスプロケットホイールとアイドラホイールとに、ローラーチェーン状に連結したリンク部材を掛け回すとともに、該リンク部材の外周にシューを着脱可能に取り付けた構造を有している。また、シューの外面（接地面側）には、舗装路面の保護などを目的としてゴムパッドが取り付けられるように形成されている（例えば、特許文献１参照。）。   In general, metal crawlers used in various construction machines hang a link member connected in the form of a roller chain between sprocket wheels and idler wheels arranged at both front and rear ends, and the outer periphery of the link member. The shoe has a structure in which the shoe is detachably attached. Further, a rubber pad is formed on the outer surface (grounding surface side) of the shoe so as to protect the paved road surface (see, for example, Patent Document 1).

特開２００４−１３６７５３号公報JP 20041366753 A

比較的小型のバックホーのように、作業場所が特定されない建設機械の場合は、舗装路面での作業や走行を考慮してシューの外面にゴムパッドを装着できるようにしており、比較的大型のバックホーであっても、ゴムパッドを装着した状態で荷台に積載しても輸送制限高さを超えないように設計されている。   In the case of a construction machine where the work location is not specified, such as a relatively small backhoe, a rubber pad can be attached to the outer surface of the shoe in consideration of work and running on the paved road surface. Even if it is, it is designed so that it does not exceed the transport limit height even if it is loaded on the carrier with the rubber pad attached.

一方、大型の建設機械、例えば大型の杭打機やクレーンは、安定した状態で杭打ち作業を行わなければならないことから、敷鉄板を敷いた場所で作業を行うようにしているため、舗装路面を走行することは想定しておらず、シューの外面が接地した状態で全高が輸送制限高さ未満になるように設計している。したがって、走行時の静粛性を求めるため、杭打機に標準的に設けられているクローラの外面にゴムパッドを装着すると、トレーラの荷台に載置したときに輸送制限高さを超えてしまう場合がある。この場合は、輸送前に少なくとも接地する部分のシューからゴムパッドを取り外さなければならず、輸送後に再びゴムパッドを装着する作業を行わなければならなかった。   On the other hand, large construction machines, such as large pile drivers and cranes, have to perform pile driving work in a stable state, so work is performed in a place where a laid iron plate is laid. It is not assumed that the vehicle will run, and the overall height is less than the restricted transport height with the outer surface of the shoe in contact with the ground. Therefore, if a rubber pad is attached to the outer surface of a crawler that is provided as a standard in the pile driving machine in order to obtain quietness during traveling, the transport limit height may be exceeded when it is placed on the trailer platform. is there. In this case, the rubber pad had to be removed from at least the portion of the shoe to be grounded before transportation, and the work of attaching the rubber pad again had to be performed after transportation.

そこで本発明は、ゴムパッドを装着しても全高を輸送制限高さ未満に抑えることができるとともに、走行時の駆動力をゴムパッドに確実に伝達することができる構造を備えたクローラ及びこのクローラを履いた大型の建設機械を提供することを目的としている。   Accordingly, the present invention provides a crawler having a structure capable of suppressing the overall height to less than the transportation limit height even when a rubber pad is attached, and capable of reliably transmitting the driving force during traveling to the rubber pad, and the crawler. The purpose is to provide large construction machines.

上記目的を達成するため、本発明のクローラは、複数の金属製のクローラシューをリンクピンにて無端状に連結するとともに、前記クローラシューの外面にゴムパッドを着脱可能に装着したクローラにおいて、前記クローラシューは、長方形状の基板と、該基板の長辺側からそれぞれ突出して隣接するクローラシューに前記リンクピンにて連結される連結部と、前記基板の各長辺に沿って基板外面方向にそれぞれ突設した一対のゴムパッド保持片と、前記基板の内面中央部に突設した係合突起と、前記基板の短辺側内面にそれぞれ形成したゴムパッド固定ボルト装着用凹部とを備え、前記ゴムパッドは、前記ゴムパッド保持片の間に形成される凹部に嵌入する凸部と、ゴムパッド保持片より外側に突出する接地部と、前記ゴムパッド固定ボルト装着用凹部に設けられたボルト挿通孔に挿通される固定ボルトとを備えていることを特徴としている。   In order to achieve the above object, the crawler of the present invention is a crawler in which a plurality of metal crawler shoes are connected endlessly by link pins, and a rubber pad is detachably attached to the outer surface of the crawler shoe. The shoe includes a rectangular substrate, a connecting portion that protrudes from the long side of the substrate and is connected to an adjacent crawler shoe by the link pin, and a substrate outer surface direction along each long side of the substrate. A pair of protruding rubber pad holding pieces, an engaging protrusion protruding from the inner surface central portion of the substrate, and a rubber pad fixing bolt mounting recess formed respectively on the inner surface of the short side of the substrate, the rubber pad, A protrusion that fits into a recess formed between the rubber pad holding pieces, a grounding portion that protrudes outward from the rubber pad holding piece, and the rubber pad fixing bolt. It is characterized in that a fixing bolt inserted through the bolt insertion hole provided in the mounting recess.

また、前記クローラシューは、前記一対のゴムパッド保持片の間に、該ゴムパッド保持片と平行な方向の中間保持片が突設されるとともに、前記ゴムパッドは、前記凸部に、前記中間保持片が挿入される係合溝を備えていると好適である。さらに、本発明の建設機械は、このようなクローラを履いた建設機械であることを特徴としている。   The crawler shoe has an intermediate holding piece protruding in a direction parallel to the rubber pad holding piece between the pair of rubber pad holding pieces, and the rubber pad has the intermediate holding piece on the convex portion. It is preferable that an engagement groove to be inserted is provided. Furthermore, the construction machine according to the present invention is a construction machine equipped with such a crawler.

本発明のクローラによれば、リンク部材を設けずに基板から前後方向に突出させた連結部をリンクピンにて連結するとともに、基板の外面に突設したゴムパッド保持片の間でゴムパッドを凹凸嵌合させた状態で保持するので、リンク部材の分だけ高さを低く抑えることができるだけでなく、駆動力をゴムパッドに効率よく確実に伝達することができる。したがって、このようなクローラを履いた大型の建設機械は、クローラにゴムパッドを装着しても全高が輸送制限高さを超えることがなくなる。さらに、駆動力を凹凸嵌合によって受ける状態になるので、ゴムパッド固定ボルトの負荷を軽減でき、ゴムパッドの接地面から連結部やリンクピンまでの距離を短くできるので、これらに掛かる負担を軽減することができる。加えて、中間保持片を設けることによってゴムパッドをより確実に保持することができる。また、リンク部材を省略できるので部品点数の低減及び製造コストの削減を図れる。   According to the crawler of the present invention, the connecting portion protruding in the front-rear direction from the substrate without using the link member is connected by the link pin, and the rubber pad is fitted between the rubber pad holding pieces protruding from the outer surface of the substrate. Since they are held in the combined state, not only can the height be kept low by the amount of the link member, but also the driving force can be efficiently and reliably transmitted to the rubber pad. Therefore, in a large construction machine wearing such a crawler, even if a rubber pad is attached to the crawler, the total height does not exceed the transport limit height. In addition, since the driving force is received by the concave and convex fitting, the load on the rubber pad fixing bolt can be reduced, and the distance from the rubber pad grounding surface to the connecting part and link pin can be shortened, so the burden on these can be reduced. Can do. In addition, the rubber pad can be more reliably held by providing the intermediate holding piece. Further, since the link member can be omitted, the number of parts and the manufacturing cost can be reduced.

前記クローラ１１は、複数の金属製のクローラシュー１２をリンクピン１３にて無端状に連結し、スプロケットホイール２６とアイドラホイール２７とに掛け回したものであって、クローラシュー１２は、車体幅方向に長辺１２ａを、車体前後方向に短辺１２ｂを有する長方形状の基板１２ｃと、該基板１２ｃの長辺１２ａ側からそれぞれ前後方向に突出して隣接するクローラシュー１２に前記リンクピン１３にて連結される連結部１２ｄ，１２ｄと、前記基板１２ｃの各長辺１２ａに沿って基板外面方向にそれぞれ突設した一対のゴムパッド保持片１２ｅ、１２ｅと、前記基板１２ｃの内面中央部に突設された係合突起１２ｆと、前記基板１２ｃの短辺１２ｂ側端部の内面にそれぞれ形成したゴムパッド固定ボルト装着用凹部１２ｇ，１２ｇとを備えている。また、両ゴムパッド保持片１２ｅ、１２ｅの間には、これらと平行に中間保持片１２ｈが設けられ、各ゴムパッド固定ボルト装着用凹部１２ｇには、ボルト挿通孔１２ｉがそれぞれ設けられている。   The crawler 11 is formed by connecting a plurality of crawler shoes 12 made of metal endlessly with link pins 13 and hung around a sprocket wheel 26 and an idler wheel 27. The long side 12a is connected to the rectangular board 12c having the short side 12b in the longitudinal direction of the vehicle body, and the crawler shoe 12 protruding in the front-rear direction from the long side 12a side of the board 12c by the link pin 13. And a pair of rubber pad holding pieces 12e, 12e projecting in the direction of the substrate outer surface along the long sides 12a of the substrate 12c, and projecting from the center of the inner surface of the substrate 12c. Rubber pad fixing bolt mounting recesses 12g and 12 formed on the inner surface of the engagement protrusion 12f and the short side 12b end of the substrate 12c, respectively. It is equipped with a door. An intermediate holding piece 12h is provided between the rubber pad holding pieces 12e and 12e in parallel therewith, and a bolt insertion hole 12i is provided in each rubber pad fixing bolt mounting recess 12g.

前記連結部１２ｄは、一方の長辺１２ａから突出した２個の幅広の第１係合凸部１２ｋ，１２ｋと、該第１係合凸部１２ｋ，１２ｋを両側から挟み込む位置に他方の長辺１２ａから突出した４個の幅狭の第２係合凸部１２ｍ，１２ｍとを有しており、各係合凸部１２ｋ，１２ｍには、幅方向に貫通したピン挿通孔１２ｎが形成されている。また、長辺１２ａの中央下部には、第２係合凸部１２ｍの外側の形状に対応した突出片１２ｐが設けられ、幅方向両側端部に位置する第２係合凸部１２ｍの外側には、リンクピン抜け止めボルト１４を取り付けるための通孔１２ｑを形成した突片１２ｒが設けられている。   The connecting portion 12d has two wide first engaging convex portions 12k and 12k protruding from one long side 12a, and the other long side at a position where the first engaging convex portions 12k and 12k are sandwiched from both sides. 12a and 4m, and a pin insertion hole 12n penetrating in the width direction is formed in each of the engagement protrusions 12k and 12m. Yes. Further, a projecting piece 12p corresponding to the outer shape of the second engaging convex portion 12m is provided at the center lower portion of the long side 12a, and on the outer side of the second engaging convex portion 12m located at both ends in the width direction. Is provided with a projecting piece 12r having a through hole 12q for attaching the link pin retaining bolt 14.

クローラシュー１２の連結は、第２係合凸部１２ｍ，１２ｍの間に形成される二つの凹部１２ｓに、隣接するクローラシュー１２から突出した第１係合凸部１２ｋをそれぞれ挿入して両係合凸部を噛み合わせた状態とし、前記ピン挿通孔１２ｎに、両側から前記リンクピン１３，１３をそれぞれ挿入し、通孔１２ｑに挿通したリンクピン抜け止めボルト１４をナットで螺着してリンクピン１３を抜け止めすることにより行われる。走行フレーム２５に組み付けられたクローラ１１は、係合突起１２ｆがスプロケットホイール２６の係合凹部２６ａに係合することによって駆動され、係合突起１２ｆがアイドラホイール２７、転輪２８及びガイド部材２５ａの溝部（図示せず）にガイドされて走行フレーム２５の外周を循環する状態になる。   The crawler shoe 12 is connected by inserting the first engaging convex portions 12k protruding from the adjacent crawler shoes 12 into the two concave portions 12s formed between the second engaging convex portions 12m and 12m. With the mating projections engaged, the link pin 13, 13 is inserted into the pin insertion hole 12n from both sides, and the link pin retaining bolt 14 inserted through the through hole 12q is screwed with a nut to link This is done by preventing the pin 13 from coming off. The crawler 11 assembled to the traveling frame 25 is driven by the engagement projection 12f engaging with the engagement recess 26a of the sprocket wheel 26, and the engagement projection 12f is driven by the idler wheel 27, the wheel 28, and the guide member 25a. Guided by a groove (not shown), the outer periphery of the traveling frame 25 is circulated.

クローラシュー１２の外面に着脱可能に装着されるゴムパッド１５は、ウレタンなどの合成ゴムによって形成されるものであって、反接地面側となる内側面には、ゴムパッド保持片１２ｅ、１２ｅ及び中間保持片１２ｈによって形成される凹凸に対応した凹凸、すなわち、クローラシュー１２の外面に形成された幅方向の２条の凹部１２ｔ，１２ｔに嵌入する２条の凸部１５ａ及び中間保持片１２ｈが挿入される係合溝１５ｂが設けられ、各凸部１５ａの幅方向両端部には、前記ボルト挿通孔１２ｉに挿通されるゴムパッド固定ボルト１６がそれぞれ埋め込まれている。また、ゴムパッド１５の外側面には、ゴムパッド保持片１２ｅ、１２ｅ及び中間保持片１２ｈの突出端より外側に突出する接地部１５ｃが設けられている。   The rubber pad 15 that is detachably attached to the outer surface of the crawler shoe 12 is formed of synthetic rubber such as urethane. The rubber pad holding pieces 12e and 12e and the intermediate holding member are provided on the inner surface that is the anti-ground surface side. Concavities and convexities corresponding to the concavities and convexities formed by the pieces 12h, that is, the two convex portions 15a and the intermediate holding pieces 12h that are inserted into the two concave portions 12t and 12t in the width direction formed on the outer surface of the crawler shoe 12 are inserted. Engaging grooves 15b are provided, and rubber pad fixing bolts 16 inserted into the bolt insertion holes 12i are embedded in both ends in the width direction of the respective convex portions 15a. Further, the outer surface of the rubber pad 15 is provided with a grounding portion 15c that protrudes outward from the protruding ends of the rubber pad holding pieces 12e and 12e and the intermediate holding piece 12h.

このゴムパッド１５は、ゴムパッド固定ボルト１６をボルト挿通孔１２ｉに挿通するとともに、各凸部１５ａを各凹部１２ｔにそれぞれ嵌入させ、ボルト挿通孔１２ｉから突出したゴムパッド固定ボルト１６にナット１６ａを締結することにより、クローラシュー１２の外面に凹凸嵌合した状態で装着される。このとき、基板１２ｃの端部にゴムパッド固定ボルト装着用凹部１２ｇを形成しているので、ゴムパッド固定ボルト１６やナット１６ａがクローラ１１の内周側に突出することはない。   The rubber pad 15 is configured such that the rubber pad fixing bolt 16 is inserted into the bolt insertion hole 12i, the convex portions 15a are inserted into the concave portions 12t, and the nut 16a is fastened to the rubber pad fixing bolt 16 protruding from the bolt insertion hole 12i. Accordingly, the crawler shoe 12 is mounted in an unevenly fitted state on the outer surface. At this time, since the rubber pad fixing bolt mounting recess 12g is formed at the end of the substrate 12c, the rubber pad fixing bolt 16 and the nut 16a do not protrude toward the inner peripheral side of the crawler 11.

ゴムパッド１５をクローラシュー１２の外面に装着した状態では、ゴムパッド１５の凸部１５ａが、ゴムパッド保持片１２ｅ、１２ｅ及び中間保持片１２ｈで形成された凹部１２ｔに嵌入しているので、ゴムパッド固定ボルト１６にはほとんど負荷が掛からない状態で、クローラシュー１２からの駆動力をゴムパッド１５に効率よく伝達することができる。さらに、基板１２ｃの前後に連結部１２ｄが直線的に突出しているので、スプロケットホイール２６からの駆動力をリンクピン１３を介して各クローラシュー１２に効率よく伝達することができる。   In a state where the rubber pad 15 is mounted on the outer surface of the crawler shoe 12, the convex portion 15a of the rubber pad 15 is fitted into the concave portion 12t formed by the rubber pad holding pieces 12e and 12e and the intermediate holding piece 12h. The driving force from the crawler shoe 12 can be efficiently transmitted to the rubber pad 15 with almost no load applied to the rubber pad 15. Furthermore, since the connecting portion 12d projects linearly before and after the substrate 12c, the driving force from the sprocket wheel 26 can be efficiently transmitted to each crawler shoe 12 via the link pin 13.

また、クローラ１１の内周側にリンク部材が設けられていないため、ゴムパッド１５を装着したときの杭打機２１の全高を、従来の構造のクローラにゴムパッドを装着した場合に比べて低くすることができる。これにより、リーダや手摺などを取り外すことによって杭打機２１の全高を輸送制限高さ未満に抑えることができ、杭打機２１を低床トレーラの荷台に積載して運搬することができる。しかも、クローラ１１の構造を変更するだけでゴムパッド１５の装着に対応することが可能となるので、各種機器配置の変更を伴うおそれがある上部旋回体２３の設計変更を行わずにすみ、製造後の杭打機への対応も可能となる。さらに、本発明のクローラは、前記杭打機に限らず、各種大型建設機械に適用可能である。   Moreover, since the link member is not provided on the inner peripheral side of the crawler 11, the overall height of the pile driving machine 21 when the rubber pad 15 is attached is made lower than when the rubber pad is attached to the crawler having a conventional structure. Can do. Thereby, by removing a leader, a handrail, etc., the total height of the pile driving machine 21 can be suppressed to less than the transportation restriction height, and the pile driving machine 21 can be loaded and transported on the loading platform of the low floor trailer. Moreover, since it is possible to cope with the mounting of the rubber pad 15 only by changing the structure of the crawler 11, it is not necessary to make a design change of the upper swing body 23 that may be accompanied by a change in the arrangement of various devices. It becomes possible to correspond to the pile driver. Furthermore, the crawler of this invention is applicable not only to the said pile driver but to various large sized construction machines.
