Abstract
The invention relates to the technical field of stratum tunneling tools and in particular relates to a wavy spring energy-supply end face sealing system for a TBM hob. The wavy spring energy-supply end face sealing system comprises a tool rest, a tool body, a tool rest metal seal ring, a tool rest wavy spring, a tool rest rubber seal ring, a tool body metal seal ring, a tool body wavy spring and a tool body rubber seal ring, wherein the tool rest rubber seal ring is arranged in a tool rest mounting slot; the tool body rubber seal ring is arranged in a tool body mounting slot; the tool rest wavy spring is arranged in a tool rest wavy spring mounting slot; the tool body wavy spring is arranged in a tool body wavy spring mounting slot; the tool rest metal seal ring and the tool rest wavy spring are arranged in a tool rest seal slot; the tool body metal seal ring and the tool body wavy spring are arranged in a tool body seal slot. The sealing system is high in overall high-temperature resistance, long in service life and high in safety; the metal seal ring and the wavy spring are reusable, so that the economic benefits are notable.
Description
technical field [0001] The invention relates to the technical field of stratum excavation tools, in particular to a wave spring energy-powered end face sealing system for a TBM hob and an installation method thereof. Background technique [0002] TBM hobs are key components of shield tunneling for rock breaking, and are widely used in subway construction, tunnel engineering, and construction of water diversion culverts. [0003] TBM hob rock breaking mechanism: Under the strong thrust of the shield machine, the cutter head is pressed into the rock formation, the hob revolves around the central axis of the cutter head, and at the same time the hobs also rotate around their respective cutter axes, so that the hob Upward continuous rolling, the cutter head applies push and rolling force (torque) to the cutter ring, the thrust makes the cutter ring press into the rock mass, and the rolling force makes the cutter ring roll against the rock mass, through the extrusion and rolling ...
