Problems solved by technology

The current off-road tracked vehicles with two tracks on land cannot meet the complex requirements of cobalt crust mining in terms of obstacle surmountability and mobility.
The walking plan for cobalt crust mining proposed by the United States is a tracked vehicle that uses plane hinges to connect four crawlers to the same vehicle body. Due to the huge body of the mining vehicle, it is difficult for this type of crawler vehicle to turn and has poor maneuverability.

Abstract

The invention discloses a cobalt crust mining articulated crawler walking device. A front crawler vehicle (3) is connected with a back crawler vehicle (4) by an articulating device (2) with multiple freedom degrees; and the articulating device (2) generates the pitching movement around z axis, the turning movement around y axis and the overturning movement around x axis between the front crawler vehicle (3) and a back crawler vehicle (1). The scheme of the cobalt crust mining articulated crawler walking device improves the adhesive attraction, the obstacle detouring ability, the walk stability, the flexibility and the passing ability of the vehicle body. Meanwhile, the articulating device has reliable structure, and is convenient in loading and unloading; and the articulated crawler walking device can be changed into two independent crawler vehicles as required.

Description

technical field [0001] The invention relates to a traveling device for seabed cobalt crust mining, in particular to a traveling device in which front and rear crawler vehicles are connected by a multi-degree-of-freedom hinge device. Background technique [0002] Cobalt crust is a seabed mineral resource rich in cobalt, nickel, copper, zinc, iron and other metals. Cobalt crusts are deposited on the side surface of seamounts at a water depth of 800-2800m in the ocean. Most of the topographic slopes in the rich ore areas are 10-35°, and steps, cliffs and grooves often appear. Due to the complexity and irregularity of the terrain where the cobalt crust is deposited, as well as the influence of various factors such as seawater resistance, mining excavation force, and long pipeline resistance, the traveling device for subsea cobalt crust mining should have super good Excellent obstacle and climbing performance, maneuverability and heavy load. The current off-road crawler vehicle...
