Document Type and Number:
WIPO Patent Application WO/2021/232373
Kind Code:
A1
Abstract:
Provided are a large machine having a mechanism for the fast disassembly and assembly of upper and lower vehicle assemblies, and a loading and unloading method. The large machine comprises: an upper vehicle assembly (1) including a hydraulic system; a lower vehicle assembly (3) including a walking mechanism; and a slewing bearing (4) mounted between the upper vehicle assembly (1) and the lower vehicle assembly (3), wherein the upper vehicle assembly (1) or the lower vehicle assembly (3) is connected to the slewing bearing (4) by means of a fast disassembly and assembly mechanism, and the upper vehicle assembly (1) is provided with several jacking stabilization oil cylinders (2) which independently support the upper vehicle assembly (1) on the ground. After the upper vehicle assembly (1) and the lower vehicle assembly (3) are separated, the hydraulic system of the upper vehicle assembly (1) is connected to the walking mechanism of the lower vehicle assembly (3) by means of a lengthened hydraulic pipe (11), such that the lower vehicle assembly (3) is controlled to move by means of the upper vehicle assembly (1). The large machine can achieve quick separation of the upper vehicle assembly from the lower vehicle assembly, achieve autonomous loading, unloading and transportation without requiring the aid of an external force after separation, reduce operation and running difficulty, and reduce usage costs.
