Description

本発明は、装軌式車両の走行に際して引き起こされるシュープレートとの接触による舗装路面、整地路面の損傷を防止する路面損傷防止具に関するものである。   The present invention relates to a road surface damage prevention device that prevents damage to a paved road surface and a leveling road surface caused by contact with a shoe plate caused during traveling of a tracked vehicle.

従来、圧雪車や雪上車、油圧ショベル、ブルドーザー等の装軌式車両に装着される履帯は、複数の鋼製シュープレートを環状につなぎ合わせたものが多く使用されており、該シュープレートの本体部分の先端に設けられた爪部を接地面に食い込ませることによりトラクション能力を高めて雪上、不整地、悪路での効率的な走行を可能としている。   Conventionally, a crawler track mounted on a tracked vehicle such as a snowplow, a snow vehicle, a hydraulic excavator, a bulldozer, etc., is often used by connecting a plurality of steel shoe plates in an annular shape. The claw part provided at the tip of the part is made to bite into the ground contact surface, thereby improving the traction ability and enabling efficient running on snow, rough terrain and rough roads.

従来のこの種の履帯は、舗装路面や整地路面をそのまま走行するとき、シュープレートの先端に設けられた爪部が路面に接触してその損傷を引き起こすのが避けられないことから、その防止策として、シュープレートの接地面にゴム等の弾性体から構成された弾性体履板を取り付けて舗装路面や整地路面を走行するようにしている。   This type of conventional crawler belt is a preventive measure because it is inevitable that the claw part provided at the tip of the shoe plate contacts the road surface and causes damage when traveling on a paved road surface or a leveled road surface as it is. As described above, an elastic body shoe plate made of an elastic body such as rubber is attached to the ground contact surface of the shoe plate so as to travel on a paved road surface or a leveled road surface.

この点に関する従来技術として特許文献１〜５には、履帯の幅方向の全域をその全周にわたって覆う構造のものが提案されている。また、特許文献６〜１５には、履帯の幅方向及びその周りに沿って多数の弾性体履板を配置し、この弾性体履板にて履帯を、路面から離して路面の損傷を防止するようにしたものが提案されている。   Patent Documents 1 to 5 as conventional techniques regarding this point propose a structure that covers the entire area of the crawler belt in the width direction over its entire circumference. Further, in Patent Documents 6 to 15, a large number of elastic body tracks are arranged along and around the width direction of the crawler belt, and the crawler belt is separated from the road surface by this elastic body foot plate to prevent damage to the road surface. Something like this has been proposed.

ところで、履帯の幅方向の全域をその全周にわたって覆う上記特許文献１〜５に開示された弾性体履板は、製作費自体、非常に高価になる。また、路面との接触により痛みやすく部分的な損傷が生じた場合であっても一括して交換する必要があるうえ、部分的な修理を行うにしても強固な構造体が必要になり、メンテナンスにかかるコストも上昇せざるを得ない状況にある。   By the way, the elastic body footboard disclosed in Patent Documents 1 to 5 that covers the entire area in the width direction of the crawler belt over its entire circumference is very expensive. In addition, even if partial damage is easily caused by contact with the road surface, it is necessary to replace them all at once, and even if partial repair is performed, a strong structure is required. The cost of this is inevitable.

一方、上記特許文献６〜１５に開示された弾性体履板は、履帯の幅方向およびその周りに所定の間隔でもって点在配置するものであり、上記特許文献１〜５に比較して製作費は安価ではあるものの、メンテナンス等を考慮するとそれにかかるコストは高価なものになることに変わりはないものである。   On the other hand, the elastic body cover plates disclosed in Patent Documents 6 to 15 are arranged in a dotted manner with a predetermined interval around the width direction of the crawler belt and the periphery thereof. Although the cost is low, considering the maintenance and the like, the cost is still high.

なお、装軌式車両の履帯を覆う弾性体履板は、該装軌式車両を作業場まで移動させるとき時に使用されるものであるから、その装着、取り外しが簡単であり、しかも、メンテナンスにかかる労力やそれにかかる維持費も極力抑制できることが求められる。   In addition, since the elastic body cover plate that covers the track of the tracked vehicle is used when the tracked vehicle is moved to the work place, it is easy to install and remove, and it takes maintenance. It is required that labor and maintenance costs can be minimized.

本発明の課題は、メンテナンス等にかかる労力やコストの抑制が可能で、かつ、履帯に対して簡便に装着、取り外しを行うことができる装軌式車両用路面損傷防止具を提案するところにある。   An object of the present invention is to propose a track-type vehicle road surface damage prevention device that can reduce labor and cost for maintenance and the like and can be easily attached to and detached from a crawler belt. .

本発明は、上記課題を解決するためになされたものである。すなわち、本発明は、装軌式車両の履帯を構成する複数のシュープレートのそれぞれにつき、その幅方向の少なくとも２個所に装着され、該装軌式車両の走行に伴う該シュープレートの、路面との接触を回避する路面損傷防止具であって、前記シュープレートに着脱自在に連結されるホルダーと、このホルダーに固定保持され、前記装軌式車両の走行時に路面に接地する弾性体パッドとを備え、前記ホルダーは、前記シュープレートの本体部分に連結ボルトを介して直接つながる継手部と、この継手部に一体連結して前記弾性体パッドを固定保持する台座からなることを特徴とする装軌式車両用路面損傷防止具である。   The present invention has been made to solve the above problems. That is, the present invention relates to each of a plurality of shoe plates constituting a track of a tracked vehicle, mounted at at least two locations in the width direction thereof, and the road surface of the shoe plate as the tracked vehicle travels. And a holder that is detachably connected to the shoe plate, and an elastic pad that is fixedly held by the holder and contacts the road surface when the tracked vehicle is running. And the holder comprises a joint part directly connected to the main body portion of the shoe plate via a connection bolt, and a base that is integrally connected to the joint part and fixedly holds the elastic pad. This is a road surface damage prevention device for a vehicle.

上記の構成からなる装軌式車両用路面損傷防止具においては、
１）継手部を、前記履帯のシュープレートの本体部分の前面及び背面の少なくとも一方を覆う板部材と、この板部材につながり、該シュープレートの先端爪部を差し込む凹所が形成された溝型部材から構成すること、
２）継手部は、シュープレートの本体部分の前面及び背面の少なくとも一方を覆う板部材に、該シュープレートとの締結に使用する連結ボルトを通す貫通開孔を有するものとすること、さらに、
３）シュープレートの本体部分の前面及び背面の少なくとも一方を覆う板部材は、連結ボルトによる締結前には、シュープレートの本体部分との相互間にて隙間を隔てて配置されるが、該連結ボルトによる締結時の弾性変形によって該シュープレートの本体部分に接触し、かつ、該シュープレートの本体部分から離反する向きの反発力を生じさせるもので構成すること、
が、課題解決のための具体的手段として好ましい。 In the track-type vehicle road surface damage prevention device configured as described above,
1) A groove member in which the joint portion is formed with a plate member that covers at least one of the front surface and the back surface of the body portion of the shoe plate of the crawler belt, and a recess that is connected to the plate member and into which the tip claw portion of the shoe plate is inserted. Consisting of members,
2) The joint portion has a through-hole through which a connecting bolt used for fastening with the shoe plate is passed through a plate member that covers at least one of the front surface and the back surface of the body portion of the shoe plate.
3) The plate member covering at least one of the front surface and the back surface of the body portion of the shoe plate is disposed with a gap between the plate member and the body portion of the shoe plate before fastening by the connecting bolt. Comprising a repulsive force that comes into contact with the body portion of the shoe plate by elastic deformation at the time of fastening with a bolt and that is away from the body portion of the shoe plate;
However, it is preferable as a specific means for solving the problem.

上記の構成からなる本発明の装軌式車両用路面損傷防止具によれば、該路面損傷防止具を、履帯を構成するシュープレートに着脱自在に連結されるホルダーと、このホルダーに固定保持され、装軌式車両の走行に際して路面に接地する弾性体パッドとによって構成したため、該シュープレートが直接路面に接触することがなく、路面の損傷を防止することができる。   According to the track-type vehicle road surface damage prevention device of the present invention having the above-described configuration, the road surface damage prevention device is detachably coupled to a shoe plate constituting a crawler belt, and is fixedly held by the holder. Further, since the elastic pad is grounded to the road surface when the tracked vehicle travels, the shoe plate does not directly contact the road surface, and the road surface can be prevented from being damaged.

また、本発明の路面損傷防止具は、各シュープレートのそれぞれにつき、少なくとも幅方向の２個所に装着することができる。すなわち、本発明の路面損傷防止具は、シュープレートに部分的（局所的）に取付けられるものであって、構造が簡素化され、サイズもコンパクトであり製作にかかるコストの増大を伴うことはない。   In addition, the road surface damage preventing device of the present invention can be attached to at least two places in the width direction for each shoe plate. In other words, the road surface damage prevention device of the present invention can be partially (locally) attached to the shoe plate, the structure is simplified, the size is compact, and there is no increase in manufacturing costs. .

また、本発明の路面損傷防止具は、それ自体が損傷しても損傷した路面損傷防止具を交換するだけですみ、たとえ、装軌式車両の走行中に交換が必要になったとしても該装軌式車両を早期のうちに走行させることできる。   In addition, the road surface damage prevention device of the present invention only needs to be replaced if the road surface damage prevention device itself is damaged, even if the road surface damage prevention device needs to be replaced while the tracked vehicle is running. The tracked vehicle can be run early.

また、本発明の路面損傷防止具は、ホルダーが、シュープレートの本体部分につながる継手部と、この継手部に一体連結して弾性体パッドを固定保持する台座にて構成された簡素化された構造であるため、それ自体が損傷しても、比較的容易に修理、修復することができる。   Further, the road surface damage prevention device of the present invention is simplified in that the holder is configured by a joint portion connected to the main body portion of the shoe plate and a pedestal that is integrally connected to the joint portion and holds the elastic pad. Because of the structure, even if it is damaged, it can be repaired and repaired relatively easily.

また、本発明の路面損傷防止具によれば、弾性体パッドが磨耗等により損傷を受けても、シュープレートは、ホルダーを構成する継手部の板部材と溝型部材にて保護されているため、該シュープレートが直接接地するのを避けることができ、シュープレート自体が損傷したり、シュープレートによって路面を損傷することもない。   Further, according to the road surface damage prevention device of the present invention, even if the elastic pad is damaged by wear or the like, the shoe plate is protected by the plate member and the groove member of the joint portion constituting the holder. The shoe plate can be prevented from being directly grounded, and the shoe plate itself is not damaged and the road surface is not damaged by the shoe plate.

本発明の路面損傷防止具によれば、路面損傷防止具の、シュープレートへの取り付け、取り外しは、シュープレートの先端爪部を溝型部材に差し込み、継手部とシュープレートの本体部分とを連結ボルトで締結するだけでよいためその取り付け、取り外しが容易である。   According to the road surface damage prevention device of the present invention, the road surface damage prevention device can be attached to or removed from the shoe plate by inserting the tip claw portion of the shoe plate into the groove member and connecting the joint portion and the body portion of the shoe plate. Since it is only necessary to fasten with bolts, it is easy to attach and remove.

さらに、本発明の路面損傷防止具によれば、シュープレートの本体部分の前面及び背面の少なくとも一方を覆う板部材を、連結ボルトによる締結前に、該シュープレートの本体部分との相互間にて隙間を隔てて配置されるようにし、該連結ボルトによる締結時の弾性変形によって該シュープレートの本体部分に接触し、かつ該シュープレートの本体部分から離反する向きへの付勢力を生じさせるもので構成したため、該板部材自体が連結ボルトに締め込まれるナットの緩み止めとして機能し、装軌式車両の走行に際して付加される振動によりナットが緩んで連結ボルトが脱落するのを防止することができる。   Furthermore, according to the road surface damage prevention device of the present invention, the plate member covering at least one of the front surface and the back surface of the shoe plate main body portion is placed between the shoe plate main body portion and the shoe plate before fastening with the connecting bolt. It is arranged so as to be spaced apart, and generates an urging force in a direction that comes into contact with the body portion of the shoe plate and is separated from the body portion of the shoe plate by elastic deformation at the time of fastening by the connecting bolt. Since it comprised, this board member itself functions as a nut loosening prevention fastened by a connection bolt, and it can prevent that a connection bolt falls by the nut loosening by the vibration added at the time of running of a track type vehicle. .

The front view and (b) are side views (A-A cross section). 2 (a) to 2 (c) are views showing one of the road surface damage prevention devices attached to the crawler belts of FIGS. 1 (a) and 1 (b), and (a) is a front view thereof. (B) is a side view, (c) is a bottom view. Although the crawler belts are usually provided on both sides of the vehicle, FIGS. 1A and 1B show the crawler belt on one side of the vehicle.

図における符号１は、装軌式車両の駆動輪、２は、装軌式車両の従動輪である。駆動輪１、従動輪２は、車両の違いに応じてその位置が適宜変更されるものであり、また、該駆動輪１、従動輪２の相互間には、履帯を誘導するための転輪が配置されることがある。   In the figure, reference numeral 1 is a drive wheel of a tracked vehicle, and 2 is a driven wheel of the tracked vehicle. The positions of the driving wheel 1 and the driven wheel 2 are appropriately changed according to the difference in the vehicle, and the wheel for guiding the crawler belt is between the driving wheel 1 and the driven wheel 2. May be placed.

また、３は、駆動輪１及び従動輪２に巻き回され、駆動輪１により輪転可能な履帯である。この履帯３は、複数のシュープレート４を環状につなぎ合わせて構成されるものであって、シュープレート４のベース４ａにおいて傾斜をもって立ち上がる板状の本体部分４ｂと、この本体部分４ｂで装軌式車両の前進方向に対して角度θ（図２（ｂ）参照）が付与されて一体連結する板状の先端爪部４ｃからなっている。   Reference numeral 3 denotes a crawler belt that is wound around the drive wheel 1 and the driven wheel 2 and can be rotated by the drive wheel 1. The crawler belt 3 is formed by connecting a plurality of shoe plates 4 in an annular shape, and has a plate-like main body portion 4b that rises at an inclination on a base 4a of the shoe plate 4, and a track type with the main body portion 4b. It consists of a plate-like tip claw portion 4c that is integrally connected with an angle θ (see FIG. 2B) with respect to the forward direction of the vehicle.

また、５は、シュープレート４の幅方向の２個所に装着した例で示した路面損傷防止具（金属製部材にて構成される）である。この路面損傷防止具５は、シュープレート４に着脱自在に連結されるホルダー５ａと、このホルダー５ａに固定保持され、装軌式車両の走行時に路面に直に接地するゴムの如き弾性体パッド５ｂから構成されている。路面損傷防止具５は、シュープレート４の幅方向の２個所に装着した場合（図１（ａ）参照）について図示したが、その装着箇所は、２個所のみには限定されることはなく、シュープレート４のサイズに応じて種々増減される。   Reference numeral 5 denotes a road surface damage prevention tool (made of a metal member) shown in the example of being mounted at two locations in the width direction of the shoe plate 4. The road surface damage prevention device 5 includes a holder 5a that is detachably connected to the shoe plate 4, and an elastic pad 5b such as rubber that is fixedly held by the holder 5a and directly contacts the road surface when the tracked vehicle is traveling. It is composed of Although the road surface damage prevention device 5 is illustrated in the case where it is mounted at two locations in the width direction of the shoe plate 4 (see FIG. 1A), the mounting location is not limited to only two locations, Depending on the size of the shoe plate 4, it is increased or decreased variously.

路面損傷防止具５を構成する部材のうち、ホルダー５ａは、図２（ａ）（ｂ）に示すように、シュープレート４の本体部分４ｂに連結ボルト６を介して直接つながる継手部５ａ１と、この継手部５ａ１に溶接の如き接合手段Ｗにより一体連結し前記弾性体パッド５ｂを固定保持する台座５ａ２からなるものが適用される。 Of the components included in the preventer 5 road damage, the holder 5a, as shown in FIG. 2 (a) (b), the joint portion 5a 1 connected directly via a connecting bolt 6 to the body portion 4b of the shoe plate 4 The joint portion 5a 1 includes a pedestal 5a 2 that is integrally connected by a joining means W such as welding to hold the elastic pad 5b.

継手部５ａ１としては、この実施の形態では、シュープレート４の本体部分４ｂの前面を覆う板部材５ａ１１と、この板部材５ａ１１および台座５ａ２につながり、シュープレート４の先端爪部４ｃを差し込む凹所が形成された溝型部材５ａ１２で構成したものを例として示してある。ここに、シュープレート４の本体部分４ｂの前面とは、弾性体パッド５ｂが路面に接地している状態（図１（ｂ）拡大図参照）で、装軌式車両の前進方向に向いている側の面をいうものとし、背面とは、該前面の反対側の面をいうものとする。 In this embodiment, the joint portion 5a 1 is connected to a plate member 5a 11 that covers the front surface of the main body portion 4b of the shoe plate 4, and the plate member 5a 11 and the base 5a 2 , and the tip claw portion 4c of the shoe plate 4 is connected. It is shown as an example that is constituted by channel-shaped member 5a 12 in which the recesses were formed plugging. Here, the front surface of the main body portion 4b of the shoe plate 4 faces the forward direction of the tracked vehicle in a state where the elastic pad 5b is in contact with the road surface (see the enlarged view of FIG. 1 (b)). This means the side surface, and the back surface means the surface opposite to the front surface.

上記の構造になる路面損傷防止具５は、先端爪部４ｃの、本体部分４ｂに対する角度θが大きくても、該先端爪部４ｃを溝型部材５ａ１２の凹所に直接入れ込んで板部材５ａ１３にて該本体部分４ｂの背面を覆うことが可能（シュープレート４の本体部分４ｂが図４に示すような姿勢で路面損傷防止具５を取り付ける場合には板部材５ａ１３をシュープレート４に向けて押し当てつつ連結ボルト６においてナット６ａを締め込む必要がある）であって、このような構成の路面損傷防止具５においても上掲図１に示したものと同様、路面の損傷を確実に防止することが可能であり、メンテナンスにかかる労力やコストを抑制することができる。 The road surface damage prevention tool 5 having the above structure is a plate member in which the front end claw portion 4c is directly inserted into the recess of the groove member 5a 12 even if the front end claw portion 4c has a large angle θ with respect to the main body portion 4b. It is possible to cover the back surface of the main body portion 4b with 5a 13 (when the main body portion 4b of the shoe plate 4 is attached to the road surface damage prevention device 5 in a posture as shown in FIG. 4, the plate member 5a 13 is attached to the shoe plate 4 The nut 6a needs to be tightened with the connecting bolt 6 while pressing toward the surface), and in the road surface damage prevention device 5 having such a configuration as well as shown in FIG. This can be surely prevented, and labor and cost for maintenance can be suppressed.

図５（ａ）（ｂ）は、本発明に従う路面損傷防止具５のさらに他の実施の形態を示した図である。この例は、継手部５ａ１を、シュープレート４の本体部分４ｂの前面及び背面をそれぞれ覆い、その一端が溝型部材５ａ１２に一体連結する板部材５ａ１４、５ａ１５で構成したものである。 FIGS. 5A and 5B are views showing still another embodiment of the road surface damage preventing device 5 according to the present invention. In this example, the joint portion 5a 1 is configured by plate members 5a 14 and 5a 15 that cover the front and back surfaces of the main body portion 4b of the shoe plate 4 and one end of which is integrally connected to the groove member 5a 12. .

上記の構成からなる路面損傷防止具５は、連結ボルト６による締結前は図５（ａ）に示すように、該シュープレート４の本体部分４ｂとの相互間において隙間ｄを隔てて配置されるものであり、連結ボルト６による締結時におけるそれそのものの弾性変形によって図４（ｂ）に示すように該本体部分４ｂの前面、背面に接触する。   The road surface damage prevention tool 5 having the above-described configuration is disposed with a gap d between the shoe plate 4 and the main body portion 4b before fastening with the connecting bolt 6, as shown in FIG. As shown in FIG. 4 (b), the front and back surfaces of the main body portion 4b are brought into contact with each other by elastic deformation of itself when the connecting bolt 6 is fastened.

装軌式車両が舗装路面や整地路面を走行する際、車両には大きな振動が発生することになり、その際の振動により連結ボルト６のナット６ａが緩んで該連結ボルト６が脱落することが懸念されるが、連結ボルト６による締結時の弾性変形によってシュープレート４の本体部分４ｂの前面、背面に接触する板部材５ａ１４、５ａ１５を備えたものにあっては、該板部材５ａ１４、５ａ１５がそれぞれ本体部分４ｂから離反する向きに付勢力が生じるため、これにより、ナット６ａが簡単に緩むことがなくなり、連結ボルト６の脱落を回避することが可能となる。隙間ｄはシュープレート４の本体部分４ｂの前面あるいは背面のいずれか一方において形成するようにしてもよい。 When the tracked vehicle travels on a paved road surface or a leveled road surface, a large vibration is generated in the vehicle, and the nut 6a of the connection bolt 6 is loosened by the vibration at that time, and the connection bolt 6 may fall off. Of concern, if the plate members 5a 14 and 5a 15 are in contact with the front and back surfaces of the body portion 4b of the shoe plate 4 due to elastic deformation when fastened by the connecting bolt 6, the plate members 5a 14 since the biasing force in the direction 5a 15 is away from the body portion 4b respectively is caused by this, prevents the nut 6a loosens easily, it is possible to avoid the falling of the connecting bolt 6. The gap d may be formed on either the front surface or the back surface of the main body portion 4b of the shoe plate 4.

上記の構成からなる路面損傷防止具５にあってはナットの緩み止め防止効果が高いため、車両を高速で走行させることができる利点がある。なお、この構造においても皿ばねの同時使用も可能であり、皿ばねの併用により、ナットの緩み止め防止効果をより一層高めることができる。図３、図４に示した構成の路面損傷防止具５の板部材５ａ１１、５ａ１３においてシュープレート４の本体部分４ｂとの相互間で隙間ｄを形成するようにしてもよく、この場合も該板部材５ａ１１、５ａ１３に緩み止め効果を発揮させる付勢力を発生させることができる。 The road surface damage prevention tool 5 having the above-described configuration has an advantage that the vehicle can be driven at high speed because the effect of preventing the nut from being loosened is high. In this structure as well, the disc spring can be used at the same time, and by using the disc spring together, the effect of preventing the nut from loosening can be further enhanced. A gap d may be formed between the plate members 5a 11 and 5a 13 of the road surface damage prevention device 5 having the configuration shown in FIGS. 3 and 4 and the main body portion 4b of the shoe plate 4, and in this case as well. It is possible to generate an urging force that causes the plate members 5a 11 and 5a 13 to exhibit a loosening prevention effect.
