Abstract

PROBLEM TO BE SOLVED: To prevent skidding of a crawler for traveling in a frozen place. SOLUTION: The crawler 10 for traveling has step parts 11 and groove parts 12 extended in the width direction alternately in an outer circumference. An anti-skid tool 20 for the crawler has a mounting member 21 and an anti-skid member 22. The mounting member 21 can be mounted by holding the groove parts 12 of the crawler 10 in the width direction. The anti-skid member 22 has flexibility. The anti-skid member 22 is fixed to the mounting member 21 so that it rises higher than the step parts 11 from the groove parts 12 when the mounting member 21 is attached to the crawler 10. The anti-skid member 22 has a length abutting to upper faces of the step parts 11 in folded sides when it is folded perpendicularly to the width direction.

When the anti-skid device for a track according to the present invention is used, the mounting member is mounted so as to be sandwiched in the groove of the moving track for movement in the width direction. When the work vehicle provided with the traveling endless track is run, the endless track anti-slip device also rotates together with the traveling endless track. At a position where the non-slip member does not hit the road surface, the non-slip member rises from the groove portion higher than the step portion of the moving endless track. When the non-slip member hits the road surface along with the rotation of the moving endless track, the anti-slip member is tilted in the opposite direction to the traveling direction and is sandwiched between the stepped portion on the tilted side and the road surface. Thereby, the non-slip member increases the frictional force and can prevent the moving endless track from slipping on a frozen road surface or the like. When the non-slip member moves away from the road surface, the anti-slip member resiliently rises again from the groove. For this reason, when the work vehicle travels in the opposite direction, the non-slip member hits the road surface and is tilted in the direction opposite to the traveling direction, and is sandwiched between the stepped portion and the road surface to increase the frictional force, so that the moving The track can be prevented from slipping on a frozen road or the like.

When the work vehicle according to the present invention travels, the non-slip member also rotates together with the moving endless track.
At a position where the non-slip member does not hit the road surface, the anti-slip member rises from the groove portion higher than the step portion of the moving endless track. When the non-slip member hits the road surface along with the rotation of the moving endless track, the anti-slip member is tilted in the direction opposite to the traveling direction and is sandwiched between the stepped portion on the tilted side and the road surface. Thereby, the non-slip member can increase the frictional force and prevent the traveling endless track from slipping on a frozen road surface or the like. When the non-slip member moves away from the road surface, the anti-slip member resiliently rises again from the groove. For this reason, even when the work vehicle travels in the opposite direction, when the non-slip member hits the road surface,
The moving endless track can be prevented from slipping on a frozen road surface or the like by being tilted in a direction opposite to the traveling direction and sandwiched between the step portion and the road surface to increase the frictional force.

When the working vehicle 1 is run, the endless track slipper 20 also rotates together with the moving endless track 10. As shown in FIG. 1, in a position where the non-slip member 22 does not hit the road surface, the anti-slip member 22 is in a state of rising from the groove 12 higher than the step 11 of the moving endless track 10.
When the non-slip member 22 hits the road surface along with the rotation of the moving endless track 10, the non-slip member 22 is tilted to the side opposite to the traveling direction. The tip of the non-slip member 22 exceeds the step 11, and the non-slip member 22 is sandwiched between the step 11 on the fallen side and the road surface. Thereby, the non-slip member 22 increases the frictional force, and moves on the frozen snowy road surface, the frozen snowy road surface, the slope, or the like.
