Abstract

The invention relates to the field of manufacturing of shield cutters, in particular to an active telescopic shield cutter mechanism. A body comprises reamer assemblies and a cutter disc, the reamer assemblies are arranged on the cutter disc, and the four reamer assemblies are arranged in the center of the cutter disc in the circumferential direction at equal interval. Each reamer assembly comprises a cutter bit body, a speed reducer, a variable displacement motor and a sliding rail device, the cutter bit bodies are arranged in the sliding rail devices, the sliding rail devices are arranged in the cutter disc, the speed reducers are arranged on the rear sides of the cutter bit bodies, the variable displacement motors are arranged on the rear sides of the speed reducers, and hydraulic oil pipes are arranged on the rear sides of the variable displacement motors. The active telescopic shield cutter mechanism has the advantages that when a shield mechanism encounters large-diameter pumice stone, boulders and local hard rock in the tunneling process, an active telescopic cutter is adopted, the rotating speed of the cutter can be instantly improved or reduced easily, and breaking and tunneling can be carried out more easily.

Description

technical field [0001] The invention relates to the field of shield machine tool manufacture, in particular to an active retractable shield machine tool mechanism. Background technique [0002] With the rapid development of the economy, the population of big cities is expanding rapidly, and the traffic pressure of the whole city is also increasing day by day. After expert research and demonstration, the use of subway or light rail is the most effective way to solve the urban traffic pressure. In the construction of subways and light rails, our most commonly used construction machinery and equipment are shield machines. The shield cutting tool is the key component of the rock-breaking excavation of the shield machine. It is easily damaged during excavation and needs to be replaced frequently. The length of its service life is not only related to the quality of tool manufacturing, but also related to the opening of the cutter head, the arrangement of the tools, and the corre...
