Abstract
The utility model discloses a bolt for improving the grip of a track, which comprises a bolt main body, wherein the bolt main body is provided with a grip part which is used for being inserted into the ground to improve the grip of the external track when the external track advances after the bolt main body is arranged on the external track; the utility model improves the grip force of the external crawler when the external crawler travels through the grip part, so that the crawler can normally work in the working environment of muddy ground, the problem of crawler slip is reduced, and the working efficiency is ensured.
Description
Technical Field
The utility model relates to the field of bolts, in particular to a bolt for improving the ground gripping force of a crawler.
Background
The crawler belt has the advantages of large ground contact area, good trafficability characteristic and strong adaptability, and is widely applied to engineering machinery. The track connecting structure of the known track type working machine generally comprises a track shoe and a caterpillar link, and the track shoe and the caterpillar link are fixed together by bolts and nuts. The common hexagon head bolts and the hexagon head bolts with spherical surfaces are adopted as the bolts for fixing the track shoe and the caterpillar link.
The patent application number is CN 201120019811.8's chinese utility model patent discloses a bolt for bull-dozer or excavator track, including helmet, screw rod, the screw rod on be equipped with the external screw thread, the up end of helmet be the arc surface, the arc crooked for the opposite side that is equipped with screw rod one side to the helmet, the arc surface through the helmet up end is marchd at bull-dozer or excavator, during operation, frictional force between this arc surface can reduce its and ground well, reduces the resistance of bull-dozer or excavator advancing, during operation. However, in some muddy working environments, the bolt reduces the resistance of the bulldozer or the excavator during traveling and working, but the crawler of the bulldozer or the excavator is easy to slip during traveling and working, and the working efficiency is affected, so that the bolt capable of improving the crawler grip in the muddy ground working environment is needed.
SUMMERY OF THE UTILITY MODEL
Therefore, in view of the above problems, the present invention provides a bolt for improving the grip of a track.
In order to achieve the purpose, the technical scheme of the utility model is to provide a bolt for improving the ground gripping force of a track, which comprises a bolt main body, wherein the bolt main body is provided with a ground gripping part which is used for being inserted into the ground to improve the ground gripping force of the external track when the external track travels after the bolt main body is installed on the external track.
The further improvement is that: the cross-sectional area of the ground grabbing part is gradually reduced from top to bottom so as to reduce the resistance of the ground to the ground grabbing part when the ground grabbing part is inserted into the ground.
The further improvement is that: the ground grabbing part is a conical ground grabbing part.
The further improvement is that: and a chamfer angle for reducing the stress between the ground grabbing part and the bolt main body is arranged at the joint of the ground grabbing part and the bolt main body.
The further improvement is that: the chamfer is a circular arc chamfer.
The further improvement is that: the bolt body is provided with an anti-skidding portion which is used for improving the friction force between the bolt body and an external crawler belt after the bolt body is installed on the external crawler belt and preventing the bolt body from reversely rotating and skidding threads when the external crawler belt travels.
The further improvement is that: and the outer surfaces of the bolt main body and the grab bottom are both provided with an anti-corrosion and anti-rust layer.
The bolt for improving the grip of the track has the following beneficial effects:
1. according to the utility model, the ground grabbing part is arranged, so that the ground grabbing force of the external crawler belt during traveling is improved through the ground grabbing part, the crawler belt can normally work in the working environment of muddy ground, the problem of crawler belt slippage is reduced, and the working efficiency is ensured.
2. According to the utility model, the arc-shaped chamfer is arranged at the joint of the ground gripping part and the bolt main body, and the stress between the ground gripping part and the bolt main body is reduced through the arc-shaped chamfer, so that the problem of stress concentration is solved, and cracks and even breakage between the ground gripping part and the bolt main body are prevented when the bolt is used.
3. The anti-slip part is arranged on the bolt body, so that the friction force between the bolt body and the external crawler is improved after the bolt body is installed on the external crawler, and the bolt body 1 is prevented from reversely rotating and slipping when the external crawler travels.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: 1. a bolt body; 2. a ground-grasping part; 3. arc chamfering; 4. an anti-slip portion; 5. and a nut.
