Description

Technical Field

[0001] The utility model belongs to the technical field of track plates, and in particular relates to a combined polyurethane track plate. Background Art

[0002] Track shoes are one of the chassis parts of construction machinery and are a kind of vulnerable parts of the construction machinery used. They are often used in mechanical engineering such as excavators, bulldozers, crawler cranes, and pavers. In order to increase the grip, track shoes usually have multiple long tooth-like protrusions on them.

[0003] Publication (Announcement) No.: CN216861631U. The utility model relates to the technical field of track plates, and discloses a combined track plate, including a first track plate body and a second track plate body, wherein the first track plate body and the second track plate body are composed of a plurality of parts, and the outer surfaces of the first track plate body and the second track plate body are respectively connected with storage boxes, and the top of each storage box is provided with a buffer plate, and the two ends of the outer surfaces of the first track plate body and the second track plate body are respectively symmetrically connected with anti-skid rubber blocks. The combined track plate is connected and assembled into a track by using the first track plate body and the second track plate body. When the tracks of individual first track plate bodies and second track plate bodies are damaged, the damaged first track plate body and second track plate are replaced without replacing the entire track device, which can effectively save the track maintenance cost.
