Anti-subsidence chassis crawler device for traveling of seabed mine collecting vehicle and traveling self-rescue method thereof

Abstract

The invention discloses an anti-subsidence chassis crawler device for traveling of a seabed mine collecting vehicle. The anti-subsidence chassis crawler device comprises an upper chassis and a lower chassis which are connected together through a telescopic device, wherein the upper chassis and the lower chassis are nested together to form a sealed cavity capable of moving up and down to serve as abuoyancy cabin, an elastic air bag is arranged in the buoyancy cabin and communicated with an air compressor, outer crawlers are mounted on the left and right sides of the upper chassis, inner crawlers are mounted on the lower part of the lower chassis, and telescopic plate devices are arranged on the outer edges of the outer crawlers. The telescopic device controls the upper chassis and the lower chassis to be separated, and linkage wheels drive the inner crawlers to extend downwards to lift the vehicle body; the buoyancy cabin increases the buoyancy of the vehicle body; a quick-setting spraying device sprays an accelerator and an enhancer so as to increase the settling velocity and strength of disturbed soil; an inner plate of the telescopic plate is inserted into soft soil to increasepower; the telescopic device continuously stretches and contracts according to data feedback, adjusts the distance between the upper chassis and the lower chassis and the height of the inner crawlersso as to adapt to soil layers with different strength, achieves vehicle body lifting, and meanwhile, prevents the inner crawlers from advancing in seabed soil all the time and the vehicle body from advancing synchronously.

Description

technical field [0001] The invention relates to a deep-sea mining operation technology, in particular to a crawler device of an anti-subsidence chassis of a seabed mine collecting vehicle and a walking self-rescue method thereof. Background technique [0002] The deep seabed is rich in solid ore resources such as polymetallic nodules, polymetallic sulfides, and cobalt crusts. The proven reserves are tens of billions of tons, which is an important direction to solve the global resource and energy shortage. [0003] The occurrence environment of polymetallic nodule resources in the deep ocean floor is complex, and the polymetallic nodule resources are distributed in an area pattern, with an area enrichment degree of about 6-10 kg / m 2 , occur scattered, and only occur in the 0-25cm surface rare soft soil on the seabed. The deep-sea rare soft substratum soil is in the state of fluid soil, with low shear strength (0-6kPa) and poor bearing capacity. At present, the chassis of pol...

Problems solved by technology

However, the process is complicated, and once the area of ​​the subsidence area is too large, it will greatly affect the efficiency of travel, and due to the process of breaking ground, the subsidence area often coincides with the location of the mining area.

[0006] When the vehicle leaves the subsidence area, it is impossible to collect minerals at the same time, which will cause great waste and seriously affect the efficiency of mining ore collection
