A walking chassis of a deep-sea rare soft bottom ore collector

Abstract

The invention discloses a deep sea rare soft substrate mine collector walking chassis which comprises a traveling component. The traveling component comprises a machine frame and caterpillar band traveling mechanisms arranged on two sides of the machine frame. A slide plate used for contacting a rare soft substrate to support a mine collector is arranged below the machine frame. The deep sea rare soft substrate mine collector walking chassis has the advantages of being small in traveling resistance, low in power requirement, stable, reliable and the like.

Description

technical field [0001] The invention mainly relates to seabed mining equipment, in particular to a walking chassis of a deep-sea rare soft bottom ore collector. Background technique [0002] Polymetallic nodules are generally located in the deep sea at 4000m-6000m, distributed on the surface of thin and soft sediments, and the cohesion of sediments at 0-100cm is generally 4-12kPa. The collection of polymetallic nodules is generally carried out by crawler-type ore collectors on the seabed. However, due to the low shear strength of the deep-sea thin soft bottom, the subsidence of the body is very large, and the driving resistance of the ore collector is large, so the increase If the driving power of the mining machine is increased, it may even cause the situation that it cannot walk; moreover, the steering of the crawler mining machine generally adopts the crawler differential steering method, so the turning radius during the steering process is very large, resulting in the fa...

The collection of polymetallic nodules is generally carried out by crawler-type ore collectors on the seabed. However, due to the low shear strength of the deep-sea thin soft bottom, the subsidence of the body is very large, and the driving resistance of the ore collector is large, so the increase If the driving power of the mining machine is increased, it may even cause the situation that it cannot walk; moreover, the steering of the crawler mining machine generally adopts the crawler differential steering method, so the turning radius during the steering process is very large, resulting in the failure of the mining machine. The work efficiency is greatly reduced; if the crawler ore collector is turned in a small area, it will repeatedly damage the substrate, making the substrate more thin and soft, further increasing the subsidence of the ore collector, and may even make the collector Miner sinks in sediment and cannot drive
