る建設車両の走行装置を提供することにある。In the conventional traveling device of this building, the upper rail CFi supporting the multi-roller bl provided on the crawler track-1 is fixed to the bracket C provided on the bearing part l of the idler d, as shown in Fig. 1, and the upper rail When the length of C becomes long, a large moment M acts on the support part f. This caused problems in terms of strength, and it was not easy to adjust the guide rail due to wear on the idler d and the upper rail tread, and in particular, the track was flapping. The present invention was made in view of the above circumstances. The purpose of this is to not only reduce the moment acting on the support parts compared to conventional rails, but also to maintain the optimum rail height and prevent the tracks from flapping when running construction vehicles. The goal is to provide equipment.

数個のマルチロール５ｔ−備えている。Hereinafter, the present invention will be explained with reference to Figures 2 and below. 2, an idler 3 is pivotally supported. A crawler belt 4 is hung between the idler 3 and a sprocket (not shown) provided at the rear of the track frame I, and the crawler belt 4 is provided with a large number of multi-rolls 5t.
トラックフレームＩＫＦｉアイドラ３ｔ−前方に付勢し

ある。The truck frame IKFi idler 3t is provided with a recoil spring 6 which urges it forward and tensions the crawler track 4.

９’により上下揺動可能に取付けである。レー′Ａ−８
の先部下面にはレール８０軸線に沿うガイド＃１９が形
成しである。A support block that can be adjusted vertically is fixed to the bearing block 2, and a base of a rail 80 is attached to the support 7 so as to be swingable up and down by means of a bin member 9'. Ray'A-8
A guide #19 along the axis of the rail 80 is formed on the lower surface of the tip.
トラックフレーム１の上面にはブラケット１０が固設し

、ローラＩＩは前記レール８のガイド溝９に接していて
レール８を略水平に支持シている０レール８は履帯４の
マルｆ Ｃ１−ル５を支持している。A bracket 10 is fixedly installed on the upper surface of the track frame 1, and a four-roller 11 is pivotally supported on the bracket 10. The roller II is in contact with the guide groove 9 of the rail 8 and keeps the rail 8 approximately horizontal. The 0 rail 8 supported on the track 4 supports the circle f C1-rule 5 of the crawler track 4.
前記レール８のレール踏面１２には、アイド放傾斜部１

ンクピッチｔｐの長さ分である。The rail tread surface 12 of the rail 8 has an id release inclined portion 1.
4 and a straight line part 15 between the run-up slope part 13 and the open slope part I4, and this straight part 15 has a length at least equal to the link pitch tp.
しかして、レール８はサポート７とブラケット１０．ロ
ーラＩＩより成る支持機構ムとによる二点支持構成であ
るために１従米の片持支持構成のレールに比べて支持部
に働くモーメントは小さくなる。Thus, the rail 8 is connected to the support 7 and the bracket 10. Since it has a two-point support structure with a support mechanism consisting of rollers II, the moment acting on the support portion is smaller than that of a rail with a single-sided cantilever support structure.

１４Ｋ・至る。If the rail 8 is worn out, the support 7 adjusts it up and down to maintain the optimal rail height.The multi-roll 5 of the crawler track 4 first ran onto the sloped part 13 of the rail g and rolled on the straight part 151. Reaching the rear opening slope part 14K.
この場合直線部１５が履帯４のリンクピッチｔｐの長さ
分ｔもつために履帯４のばたつきをおさえる。In this case, since the straight portion 15 has a length t equal to the link pitch tp of the crawler belt 4, the flapping of the crawler belt 4 is suppressed.

る。As described in detail above, the misfire 8A is provided with a vertically adjustable port 7 on the bearing block 2 which is provided so that the track frame IKIII can move backward and supports the eyeton 3,
A rail 8 is provided on the support 7 so as to be swingable up and down, and a support-like structure is provided on the track frame 1 to support the rail 8 so as to be able to move back and forth in a substantially horizontal direction.
iit consists of a riding slope part 13 on the idler side, an opening slope part 14 of the sprocket hook, and a straight part I5 between the riding slope part 13 and the opening slope part 14, and the straight part 15 is at least a link of the crawler track 4. Since the pitch is equal to the length of tp, the rail 8 is supported at two points, and the moment applied to the support portion can be reduced compared to a conventional cantilever supported rail.
またレール８の上下ＦＡ整がサポート７によシできるの
でレール８が摩耗しても最適なレール高さが維持できる
。Further, since the vertical FA alignment of the rail 8 can be done by the support 7, the optimum rail height can be maintained even if the rail 8 is worn out.
