Undersea mining vehicle walking chassis

Abstract

The invention discloses a traveling chassis of a submarine mining vehicle. The traveling chassis comprises a vehicle body bracket, a crawler bracket and two traveling crawlers, wherein the two traveling crawlers are arranged at the two sides of the crawler bracket; a plurality of long toothed plates are arranged on the traveling crawlers at intervals; a plurality of short toothed plates are arranged between the adjacent long toothed plates at intervals; each long toothed plate is higher than the corresponding short toothed plate; each long toothed plate is vertical to the grounding surface of the traveling crawler, and an acute angle is formed between each long toothed plate and the traveling direction of the corresponding traveling crawler. The traveling chassis of the submarine mining vehicle has the advantages that the pushing property is good, the slippage rate is low, the energy consumption is low, the traveling chassis is suitable for deep-sea thin and soft bottom environments, and the like.

Description

technical field [0001] The invention relates to the technical field of seabed engineering operation equipment, in particular to a walking chassis of a seabed mining vehicle. Background technique [0002] Polymetallic nodules are located on seafloor sediments, often in a semi-buried state. Nodules exist at different depths of the seabed, but are most abundant in the deep seabed at a depth of 4,000 to 6,000 meters. Deep-sea sediments are heterogeneous in nature and are formed through different deposition processes. The cohesion and internal friction angle of sediments are both small, and the cohesion of silt is the smallest, which is due to its extremely high water content and fluid plastic state. , however, the proportion of silt in the seabed sediment is relatively large, which will affect the traction of the work vehicle. This is because when the mining vehicle runs on the seabed sediments, the crawler exerts a backward horizontal force on the seabed surface, and the grou...
