Description
【０００１】[0001]
本考案は、クローラ取付け、取外し用ベルトに関するものである。 The present invention relates to a crawler mounting and dismounting belt.
【０００２】[0002]
クローラの取付け、取外しは、アイドラ（遊動輪）を弛めてクローラを十分た るませてから行わなければならなかった。そして、そのたるませ量は駆動輪の駆 動突起がかわせるまで、又はクローラに形成される外れ防止突起がかわせるまで 必要であった。 The crawler had to be installed and removed after the idler (idle wheel) was loosened and the crawler was fully collapsed. The amount of slack was necessary until the driving protrusion of the drive wheel was displaced or the disengagement prevention protrusion formed on the crawler was displaced.
【０００３】[0003]
この作業には大変な時間がかかり、又、非常に大きな力を要する。従って、ク ローラの取付け、取外しは非常に嫌われていた。 本考案は、これに対処したものであり、駆動輪を駆動するだけでクローラの取 付け、取外しができるようにしたものである。 This work takes a lot of time and requires a great deal of force. Therefore, the attachment and detachment of the crawler was very disliked. The present invention addresses this problem and makes it possible to attach and detach the crawler simply by driving the drive wheels.
【０００４】[0004]
以上の課題の下、本考案は、クローラと駆動輪との間に挿入される可撓性ベル トであって、このベルトに形成される駆動輪の駆動突起突入用の突入孔の幅方向 位置が長手方向で一ピッチ毎僅かずつずれ、最終的には、少なくとも駆動突起一 個分以上ずれて形成されることを特徴とするクローラ取付け、取外し用ベルトを 提供する。 Under the above problems, the present invention is a flexible belt inserted between a crawler and a drive wheel, in which a position in the width direction of a drive hole for driving a drive wheel is formed in the belt. There is provided a crawler attachment / detachment belt characterized in that it is formed to be slightly deviated by one pitch in the longitudinal direction, and finally deviated by at least one drive protrusion.
【０００５】[0005]
以上の手段をとることにより、ベルトを駆動輪とクローラとの間に挟んで駆動 輪を駆動すると、ベルトとこれに重なるクローラが徐々に横にずれ、少なくとも 駆動輪の駆動突起をかわせるだけはずれる。このとき、クローラを横に引っ張れ ばクローラは容易に取外しできる。又、これと逆の操作をすれば、クローラの取 付けも容易にできる。 By taking the above means, when the drive wheel is driven while the belt is sandwiched between the drive wheel and the crawler, the belt and the crawler overlapping with the belt are gradually displaced laterally, and at least the drive protrusion of the drive wheel is displaced. At this time, the crawler can be easily removed by pulling it sideways. If the reverse operation is performed, the crawler can be easily attached.
【０００６】[0006]
図３は駆動輪とクローラとの関係を示す側面図、図４は断面図であるが、クロ ーラ１０は駆動輪１２、転動輪１４及び図示は省略するが遊動輪にエンドレスに 巻き掛けられる。クローラ１０の中央には駆動輪１２の駆動突起１６が突入する 突入孔１８が駆動突起１６のピッチで形成されている。尚、クローラ１０の内周 には、突入孔１８を挟む両側に遊動輪等のはずれ防止用突起２０が形成されるこ ともあり、このような場合はこのはずれ防止用突起２０の間の谷部で遊動輪等を 受けるようにしている。 3 is a side view showing the relationship between the drive wheels and the crawlers, and FIG. 4 is a cross-sectional view. The chlora 10 is endlessly wound around the drive wheels 12, the rolling wheels 14, and the idler wheels (not shown). . In the center of the crawler 10, there are formed through holes 18 into which the drive projections 16 of the drive wheels 12 project at the pitch of the drive projections 16. It should be noted that the inner periphery of the crawler 10 may have protrusions 20 for preventing disengagement of an idler wheel or the like on both sides of the protrusion hole 18. In such a case, a valley portion between the protrusions 20 for preventing disengagement may be formed. I am trying to receive idle wheels.
【０００７】 図１は本考案に係るクローラ取付け、取外し用ベルトの平面図であるが、この ベルト２２は鋼板等の可撓性材で製作され、クローラ１０と同様、駆動輪１２の 駆動突起１６が突入する突入孔２４が形成されているものである。尚、クローラ １０の内周にはずれ防止用突起２０が形成されるものにあっては、この突起２０ が突入できる突入孔２６も形成されている。FIG. 1 is a plan view of a crawler mounting / removing belt according to the present invention. The belt 22 is made of a flexible material such as a steel plate, and like the crawler 10, the driving projection 16 of the driving wheel 12 is formed. Is formed with a plunge hole 24. In addition, in the case where the deviation preventing projection 20 is formed on the inner periphery of the crawler 10, a projection hole 26 into which the projection 20 can be inserted is also formed.
【０００８】 ところで、本考案では、以上の突入孔２４の（突入孔２６も）幅方向位置が長 手方向で一ピッチ毎僅か（ａ）ずつ横にずれ、最終的には、少なくとも駆動突起 １６一個分（ｂ）以上ずれて形成されるのである。この場合の（ａ）は駆動突起 １６が突入孔２４から外れない程度であり、又、（ｂ）は駆動突起１６の幅より もかなり大きく設定される。更に、ベルト２２の厚みは駆動突起１６の丈かそれ よりもやや薄い程度に設定される。By the way, in the present invention, the widthwise position of the above-mentioned thrust hole 24 (also the thrust hole 26) is laterally displaced by a slight pitch (a) in the longitudinal direction, and finally at least the drive protrusion 16 It is formed by being shifted by one (b) or more. In this case, (a) is such that the drive projection 16 does not come off the projection hole 24, and (b) is set to be considerably larger than the width of the drive projection 16. Further, the thickness of the belt 22 is set to be the height of the drive protrusion 16 or slightly thinner than that.
【０００９】 図２はこのベルト２２を用いてクローラ２２を駆動輪１２から取り外す場合の 説明図であるが、まず、このベルト２２を駆動輪１２とクローラ１０との間に挟 み、駆動輪１２を駆動させる（このとき、遊動輪を少し弛め、クローラ１０をあ る程度たるませておくのが好ましい）。すると、ベルト２２に形成された突入孔 ２４のずれにより、ベルト２２及びクローラ１０は回転するに伴って少しずつず れて来、最終的にはクローラ１０の突入孔１８が駆動突起１６から外れた状態に なる。FIG. 2 is an explanatory view of the case where the crawler 22 is detached from the drive wheel 12 by using the belt 22, but first, the belt 22 is sandwiched between the drive wheel 12 and the crawler 10, and the drive wheel 12 is removed. (At this time, it is preferable to loosen the idler wheel a little and slacken the crawler 10 to some extent). Then, the belt 22 and the crawler 10 are gradually displaced as the belt 22 and the crawler 10 rotate due to the displacement of the plunge hole 24 formed in the belt 22, and finally the plunge hole 18 of the crawler 10 is disengaged from the drive protrusion 16. It will be in a state.
【００１０】 こうなると、クローラ１０だけを横に引っ張れば外れる。又、ベルト２２及び クローラ１０が駆動突起１６から外れた後、クローラ１０を横に引張ながら駆動 輪１２を駆動してもよい。一方、クローラ１０を駆動輪１２に取り付ける場合は 、ベルト２２の向きを前後逆にし、以上と逆の操作をすればよい。In this case, pulling only the crawler 10 to the side will remove it. Further, after the belt 22 and the crawler 10 are disengaged from the drive protrusion 16, the drive wheel 12 may be driven while pulling the crawler 10 laterally. On the other hand, when the crawler 10 is attached to the drive wheel 12, the direction of the belt 22 may be reversed and the reverse operation may be performed.
