Abstract

The invention discloses a grouser device special for a mining vehicle and capable of adapting to different deep sea surface layer soil properties. The grouser device special for the mining vehicle andcapable of adapting to the different deep sea surface layer soil properties involves a track body, a plurality of long-strip holes arranged in parallel are formed in the upper surface of the track body, a long strip-shaped grouser capable of freely moving up and down along the corresponding long-strip hole is arranged in each long-strip hole, baffles with the width larger than the width of the long-strip holes are fixed at the lower ends of the grousers, groove-type mounting seats are fixed at the lower ends of the baffles, the adjacent two grousers are in a group, the plurality of grousers are divided into a plurality of grouser combinations independent from one another, the mounting seat of each group of grousers is rotationally connected with one corresponding grouser push plate through a pin, each grouser push plate is controlled by a hydraulic control and pushing device arranged in a cavity in the middle of the track body, vane-shear apparatus is arranged at each of the front endand the rear end of the cavity in the middle of the track body, and the vane-shear apparatus is connected with controllers of the hydraulic control and pushing devices through data lines. The invention further discloses a using method of the device.

Description

technical field [0001] The invention relates to a submarine engineering operation equipment technology, in particular to a special crawler device and method for mining vehicles that can adapt to the properties of different deep-sea surface soils. 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 resulting shear force constitutes the main forward driving force of the crawler mining vehicle. However, the seabed topsoil has the property of disturbance fluidization and is extremel...
