的にも問題があるものであつた。 Conventionally, a crawler track guard plate provided in a track running device has a mounting structure in which it is integrally attached to the lower surface of a running frame by welding. If the guard plate is provided integrally with the running frame in this way, in order to replace the guard plate due to damage etc., it will be necessary to replace each running frame, which will only lead to a significant cost disadvantage. Moreover, the replacement work requires a great deal of time and effort. Furthermore, when a force is applied to the guard plate from the inside to the outside, the bending moment generated at the base end of the guard plate becomes large, which poses a problem in terms of strength.

面からボルト締めしてゆくようにしている。 Reference numeral 14 denotes a crawler track guard plate that is replaceably provided on the mounting board 13, and is formed into a substantially U-shaped plate with both front and rear ends bent outward, and approximately the upper half is attached to the mounting board 13. Inner surface 13'
It is attached with bolts 15 and nuts 16 in a polymerized state. In this case, the guard plate 14
is attached to the base plate 13, a slight gap 17 is created between the lower end of the guard plate 14 and the inner surface of the crawler track 9, and the height of the base plate 13 is made approximately half the height of the guard plate 14. Form and guard plate 1
By supporting the upper half of the guard plate 14 on the inner surface 13' of the substrate 13, when a force is applied to the tip of the guard plate 14 from the inside to the outside, the distance 1 of the bending moment generated in the guard plate 14 can be reduced. is set to the height of the lower half of the guard plate 14, thereby reducing the bending moment. Further, a mounting nut 16 is welded to the inner surface of the guard plate 14, and the bolts are tightened from the outer surface of the mounting board 13 with the nut 16 aligned with the mounting hole 18 provided in the board 13. There is.
しかも本実施例では、履帯ガード板１４を遊動
輪８、および転輪１０の側部に設けるようにし
て、遊動輪８の側部において土砂の噛み込みを防
止し、転輪１０の側部においては履帯の横振れを
防止させている。 Moreover, in this embodiment, the crawler guard plate 14 is provided on the sides of the idler wheels 8 and the rollers 10 to prevent dirt from getting caught in the sides of the idler wheels 8, and This prevents the tracks from swinging laterally.
従つて、不整地での作業等によつて履帯ガード
板１４が損傷を受けて、本来の機能が果せなくな

そしてこの取外したガード板を新たなガード板に
取替えて取付け基板１３にボルト１５により取付
けるものである。 Therefore, if the crawler guard plate 14 is damaged due to work on rough ground and cannot perform its original function, it will be replaced with a new guard plate, but in this case, the bolts 15 should be tightened. Mounting board 1
3 and the track guard plate 14, only this guard plate 14 can be removed.
Then, this removed guard plate is replaced with a new guard plate and is attached to the mounting board 13 with bolts 15.
しかも、履帯ガード板１４は横断面略コ字状に
形成しているために、上記した曲げモーメントに
充分に対抗することのできる強度を確保せしめる
ことができるのである。 Moreover, since the crawler guard plate 14 is formed to have a substantially U-shaped cross section, it can ensure sufficient strength to withstand the above-mentioned bending moment.
また、折曲した前後端縁部により、履帯内周面
の付着泥土等を確実に払拭することが可能となる
ものである。 Furthermore, the bent front and rear edges make it possible to reliably wipe away mud and the like adhering to the inner circumferential surface of the crawler belt.
更には、取付け基板１３と履帯ガード板１４と

ができるのである。 Furthermore, since both the mounting board 13 and the track guard plate 14 are formed in an inverted trapezoid shape, even though both of these plates 13 and 14 are formed in a substantially U-shaped cross section, Therefore, the work of attaching the bolts 15 in the overlapping state via the bolts 15 can be done quickly and easily.
また、同形状により、泥土等の付着が少なく、
付着した際にも落ちやすいという効果を奏する。 In addition, due to the same shape, there is less adhesion of mud etc.
It has the effect of being easy to remove even when it adheres to the surface.

ある。 Further, the longitudinal width of the crawler track guard plate 14, which directly receives external force, is formed to be larger than the longitudinal width of the mounting board 13, so that strength can be ensured. Since the upper half of the guard plate 14 attached to the mounting board 13 is supported by the inner surface 13' of the board 13, the distance 1 at which a moment occurs in response to a force directed from the inside to the outside is the guard plate 14. Since the height is the lower half of the plate 14, this bending moment can be reduced.
