Abstract

The invention discloses a shield tunneling machine based on Internet of Things signal emission in the field of shield tunneling machines. The aim is to overcome the defect of collapse of stirring blades in the prior art. According to the technical scheme, key grooves are formed in the circumferential directions of the stirring blades, the key grooves make contact with attaching pieces, the attaching pieces comprise reinforcing ribs, balls, tension springs and abutting rods, the reinforcing ribs are obliquely connected to the abutting rods, the balls are attached to the stirring blades, slide in the key grooves and are fixedly connected with the abutting rods, the tension springs are wound on the surfaces of the abutting rods, in the stirring process, due to the fact that the stirring blades are in a high-speed autorotation state, the tension springs are in a stretching state (but the tension springs are not completely straightened) at the moment, and the tension springs continuously jack up the balls under the action of the centrifugal force. Therefore, the balls are kept to continuously apply the jacking force to the stirring blades, a part of the force is borne, and meanwhile the deflected stirring blades are repaired to a certain degree.

Description

technical field [0001] The invention belongs to the field of shield machines, in particular to a shield machine based on signal transmission of the Internet of Things. Background technique [0002] The shield machine is developed on the tunnel shield technology. In 1818, Brunoll of France got inspiration from borer drilling, and first proposed the idea of ​​using shield method to build tunnels, and obtained a patent in the UK. The internal structure of the shield machine conceived by Brunoll is composed of different cells, each cell can accommodate a worker to work independently and protect the worker. The method adopted is to firmly install all the cells on the shield shell. Two methods were designed at that time, one is that when a section of tunnel excavation is completed, the entire shield shell is pushed forward by the hydraulic jack with the help of the backrest. [0003] In November 2015, in Changsha, Hunan, the first large-diameter shield machine for railways in m...
