Description

Crawler belt link capable of preventing sludge blockage

Technical Field

The utility model belongs to the technical field of engineering equipment accessories, a prevent track link that silt blockked up is related to.

Background

Crawler-type engineering equipment's walking environment is complicated, often need the operation under the environment of soft soil property, the track is that the concatenation of many links forms, need set up slot or jack with the tooth adaptation of sprocket, easily squeeze into earth or stone in slot or jack, cause the unable cooperation better with the sprocket when removing to the sprocket position of chain link, cause the track tensile force to increase, cause the damage of connecting piece and sprocket tooth portion easily, in addition, the connecting pin axle department of chain link is also dead because of long-pending mud card easily, therefore, the chain link structure of track exists and improves the space.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent track link that silt blockked up to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem of how to make the track be difficult to receive earth jam.

The purpose of the utility model can be realized by the following technical proposal: the track link capable of preventing silt from blocking is characterized by comprising two symmetrically distributed chain pieces, wherein each chain piece is provided with a fixed end and a movable end, a chain plate is arranged between the fixed ends of the two chain pieces, the movable end of each chain piece is provided with an avoidance step, the fixed end of each chain piece is provided with a first pin hole, a through hole coaxial with the first pin hole is formed in each chain plate, the movable end of each chain piece is provided with a second pin hole, the two track links are connected through a pin shaft, and the pin shaft simultaneously penetrates through the second pin hole of one link, and the first pin hole and the through hole of the other link; the chain plates extend out of the outer side face of the crawler belt to form anti-skid protrusions.

Furthermore, the chain plate and the two chain sheets are manufactured into a whole.

Furthermore, the end face of the chain plate in the width direction is flush with the outer side face of the fixed end of the chain sheet.

The track link has the advantages that: because the fixed ends of the chain plates and the chain pieces are integrally formed, the chain plates form a U-shaped structure, the chain plates not only serve as the anti-skidding bulges of the crawler belt, but also play a role in erecting the connection strength of the two chain pieces, and the pin shaft can be protected by arranging the through holes on the chain plates.

After the concatenation formed the track, form the tooth complex slot with the sprocket between the adjacent link joint, after getting into earth or stone in this slot, can extrude it when lieing in the tooth cooperation, and, because the track with sprocket contact site is the bending state, be the opening form that inboard width is less than the outside width between the adjacent link joint, earth and stone are extruded very easily, thereby make the track have the characteristic that is difficult to block up, including the round pin axle receives the protection of link joint, be difficult to store up the mud sediment in the rotation space of round pin axle, the track operation is smooth and easy, adaptive environment ability is strong.

In the figure, 1, a chain sheet; 11. a fixed end; 12. a movable end; 13. a chain plate; 14. avoiding steps; 21. a first pin hole; 22. a pin hole II; 23. and (7) a pin shaft.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and fig. 2, the track link for preventing silt blockage comprises two symmetrically distributed chain sheets 1, wherein each chain sheet 1 is provided with a fixed end 11 and a movable end 12, a link plate 13 is arranged between the fixed ends 11 of the two chain sheets 1, the movable end 12 of each chain sheet 1 is provided with an avoidance step 14, the fixed end 11 of each chain sheet 1 is provided with a first pinhole 21, the link plate 13 is provided with a through hole coaxial with the first pinhole 21, the movable end 12 of each chain sheet 1 is provided with a second pinhole 22, the two track links are connected through a pin shaft 23, and the pin shaft 23 simultaneously penetrates through the second pinhole 22 of one link, the first pinhole 21 of the other link and the through hole; the chain plate 13 extends out of the outer side surface of the crawler belt to form an anti-skid bulge, and the chain plate 13 and the two chain plates 1 are integrated.

The end surface of the chain plate 13 in the width direction is flush with the outer side surface of the fixed end 11 of the chain sheet 1, and the chain plate 13 inclines towards the rear of the outer side surface of the crawler belt, so that the function of increasing the ground grabbing force of the crawler belt is achieved.

The track link has the advantages that: because the chain plate 13 and the fixed end 11 of the chain sheet 1 are integrally formed, the chain plate 13 forms a U-shaped structure, the chain plate 13 not only serves as an anti-skidding bulge of the crawler belt, but also plays a role in supporting the connection strength of the two chain sheets 1, and the pin shaft 23 can be protected by arranging the through hole on the chain plate 13.

After the concatenation formed the track, form the tooth complex slot with the sprocket between the adjacent link joint 13, after getting into earth or stone in this slot, can extrude it when the tooth cooperates, and, because the track with sprocket contact site is the bending state, be the opening form that inboard width is less than the outside width between the adjacent link joint 13, earth and stone are extruded very easily, thereby make the track have the characteristic that is difficult to the jam, in addition, round pin axle 23 receives the protection of link joint 13, be difficult to store up the mud sediment in the rotation space of round pin axle 23, the track operation is smooth and easy, the adaptation environmental capability is strong.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
