Abstract

The invention discloses a cutter head of a multi-mode shield machine and the shield machine thereof. block and sub-beam, the center block is set in the middle of the cutter head body, the center block is provided with a hob, the center block is connected with the outer ring through the main beam, and the rear part of the center block is detachably provided with a pipeline transition Mechanism; the sub-beam is connected to the main beam through a twisted leg base, and the rear part of the sub-beam is detachably provided with a slag sliding structure; both the main beam and the sub-beam are equipped with knives. In the invention, the knives are evenly distributed, and the structure of the cutter head is reasonable. The middle part of the cutter head adopts a reinforced central block design, which reduces the deformation of the cutter head during the excavation process; The probability of build-up is reduced, reducing wear on the deck face.

Description

technical field [0001] The invention belongs to the technical field of special engineering equipment for tunnels, and in particular relates to a multi-mode shield machine cutter head and the shield machine. Background technique [0002] The safety, efficiency and controllability of the shield machine construction’s impact on the surface environment of the construction area have been widely recognized, and different types of shield machines are suitable for different hydrogeological conditions; with the diversified development of market demand for shield machines As well as the increasingly mature design, development and production technology of shield machines, it is difficult for the previous single-mode shield machines to meet the market's growing demand for construction quality and efficiency. [0003] As one of the key components of the shield machine, the cutterhead is mainly used to excavate the soil and support the tunnel face. The adaptability of the cutterhead to th...
