Automatic storing and taking method for hob of shield tunneling machine

Abstract

The invention discloses a method for automatically storing and taking a hob of a shield tunneling machine, which uses an automatic hob head and comprises the following steps of: 1, replacing a new hob with an old hob; and 2, manual tool feeding and warehousing. A certain number of new knives are stored on the automatic knife rest in advance, and when the knives are automatically replaced, the old knives are taken down from the knife disc one by one and placed on the automatic knife rest; meanwhile, new knives on the automatic knife rest are placed at designated positions on the knife disc one by one; after all the new knives are replaced, the automatic knife rest sends the old knives out of the cabin, and the old knives are manually taken down; after all old knives are taken out, new knives are manually fed, and the automatic knife rest feeds the new knives into the cabin. After the method provided by the invention is adopted, a certain number of new and old hobs can be stored on the automatic knife rest by the hobs of the shield tunneling machine, and the hobs can be automatically stored and taken according to system requirements, so that the heavy manual transfer operation in a narrow space of the shield tunneling machine is replaced. Therefore, the cutter changing operation of the shield tunneling machine is safer, more efficient and more economical.

Description

Technical field [0001] The present invention relates to an automatic access method of shield machine, belonging to the technical field of shield machine. Background technique [0002] During the use of the shield, the tool (hob) is prone to passivation, damage, etc. Taking into account the construction progress and the actual situation, it is often necessary to complete the tool replacement underground. [0003] When the artificial tool change work, it usually has a group, two of which complete tool inspection, disassembly and installation in the mud cabin, and 2 people are in the haraffle, responsible for the conveying of the tool, and the remaining one person is responsible for other auxiliary outside the people. Operation. Single tool weight is nearly 200kg, the transfer operation of the tool will consume great physical strength and affect the overall change efficiency. At the scene, two groups of people were often arranged to replace the knife, and a set of financing withdraw...
