Embodiment Construction

[0017] Such as Figure 1 to Figure 2 As shown, in this embodiment, a double independent driving system of a shield machine includes a front shield shell, a central cutting cutter head 1, a main cutter head, a soil bin, an outlet for cutting rock and soil, a screw conveyor, and the main cutter head of the shield machine The center of the disk is equipped with a central cutting cutter head 1, and an independent driving device for the center knife is installed on the center cutting cutter head 1. Such a setting can realize the independent rotation of the central cutting cutter head 1, and can speed up its speed relative to the main cutter head. , the steering can be consistent or inconsistent, and the most suitable speed can be selected according to the characteristics of the soil layer to ensure the smooth progress of the tunneling.

[0018] The independent driving device of the center knife is driven by the bearing and the transmission sleeve. The transmission sleeve is connect...

Abstract

The invention discloses a double independent driving system for a shield machine, which comprises a front shield housing, a central cutting knife plate, a main knife plate, a soil bin, a cutting ground outlet and a screw conveyor, wherein the central cutting knife plate is mounted in the center of the main knife plate of the shield machine; and a central knife independent driving device is mounted above the central cutting knife plate. The double independent driving system has the benefits that as the central knife independent driving device is mounted above the central cutting knife plate, the central cutting knife plate can rotate fast to break lithosphere, and the main knife plate rotate in a low speed to break a soft soil layer, so as to ensure that the speeds of the main knife plate and the central cutting knife plate are the same while being used for breaking special stratums, which realizes the smooth excavation of the shield machine.

Description

technical field [0001] The invention relates to a shield machine, in particular to a double independent driving system of the shield machine. Background technique [0002] The shield machine is a special construction machine used for excavation in tunnel construction. The cutter head of the large-diameter shield machine rotates at a very low speed, generally about one revolution per minute. When the shield machine passes through the cohesive soil layer, due to The front of the cutter head will be unable to operate due to the obstruction of the compacted and consolidated clay, and the central part of the large-diameter cutter head is almost motionless relative to other surrounding soils, which greatly reduces the working efficiency of the shield machine; When encountering some special strata during the process, for example, when encountering a stratum with a soft soil layer above and a hard rock layer below, the shield machine is under the geological conditions with huge diff...
