Abstract

The invention discloses a walking crawler device of a crawler-type deep sea mining vehicle, which comprises two walking crawlers installed on the two sides of a crawler support, wherein a plurality oflong crawler teeth and a plurality of short crawler teeth are arranged on the walking crawlers at intervals, and the height of the long crawler teeth is greater than that of the short crawler teeth;when the long crawler teeth are completely inserted into soil, an acute angle is formed between the arrangement direction of the long crawler teeth and the advancing direction of the walking crawler;a long toothed plate is an arc plate, the middle part of the long crawler tooth is sunken backwards relative to the advancing direction of the mining vehicle, a middle reinforcing rib beam is vertically arranged in the middle of the convex surface, and side edge reinforcing rib beams are vertically arranged at the two ends of the convex surface; the short crawler tooth is a wedge-shaped body witha certain height and width, the interior of the wedge-shaped short crawler tooth is in a hollow state, a short crawler tooth rib beam for supporting and reinforcing is arranged in the middle of an inner cavity of the wedge-shaped short crawler tooth, and stepped micro bulges are arranged on the outer surface of the wedge-shaped short crawler tooth in the length direction. The walking crawler device can enable the crawler-type deep sea mining vehicle to have better propelling performance, and prevents the crawler-type deep sea mining vehicle from slipping, sinking and laterally moving.

Description

technical field [0001] The invention relates to a seabed engineering operation equipment technology, in particular to a crawler-type deep-sea mining vehicle walking crawler device. Background technique [0002] Polymetallic nodules mainly occur in the 4000-6000m seabed surface soil. The properties of the seabed surface soil are not uniform, the cohesion and internal friction angle are both small, and the moisture content is extremely high. Based on the special mechanical properties of seabed surface soil, crawler mining vehicles have become the main equipment for seabed mining. The crawler teeth on the crawler exert a backward horizontal driving force on the seabed soil, and the seabed soil undergoes shear deformation, and the shear force generated constitutes the main forward driving force of the crawler mining vehicle. However, the seabed topsoil has the characteristics of disturbance fluidization and is extremely sensitive to external disturbances, and the strength of t...
