Abstract

The invention discloses a coring shield mechanism of a tunnel boring machine. The coring shield mechanism comprises a pushing device, a converting device and a rotating fixed base, wherein the converting device is matched with the pushing device, the rotating fixed base is arranged on one side of the converting device in a matched mode to be driven, one side of the rotating fixed base is further connected with supporting legs, and a cutter head is connected to one end of each supporting leg. The coring shield mechanism of the tunnel boring machine serves as a cutting mechanism of the tunnel boring machine, and the coring shield mechanism not only is high in efficiency, safe and reliable, but also prolongs service life of a cutting component and reduces production cost.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a core-taking shield mechanism for a boring machine. Background technique [0002] A boring machine is a machine used to dig a straight underground roadway. The roadheader is divided into open type roadheader and shield type roadheader, the price is generally more than 100 million yuan, mainly composed of walking mechanism, working mechanism, shipping mechanism and reloading mechanism. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. [0003] At present, the hard rock roadheader is mainly for full-section cutting, which has high requirements on the tool and equipment structure. It is often necessary to replace the tool during use. The speed is slow and the risk is high. In addition, the parts on the roadheader are expensive. If the parts are replaced frequently, it will damage the...
