Abstract

The invention discloses an intelligent bolt detection system and method for a main bearing of a shield tunneling machine, belongs to the technical field of shield tunneling machine maintenance, and solves the problem that the state of a bolt cannot be monitored in the prior art. The intelligent bolt detection system comprises a bolt, threaded parts are fixedly arranged at the two ends of the bolt, and a sensor is wound in a thread of each threaded part; one end of the sensor is connected with a connector, the connector is connected with a control box, the control box is connected with a console, and the technical effect of monitoring the bolt in real time is achieved.

Description

technical field [0001] The invention belongs to the technical field of shield machine maintenance, and in particular relates to an intelligent bolt detection system and method for a main bearing of a shield machine. Background technique [0002] There are many connection methods between engineering structures. Bolt connection is the most widely used connection method in engineering practice. In these structures, bolts are indispensable components and are widely used to fix various components. Structure plays a very important role. [0003] When the large-scale structure deforms, the stress carried by the bolts that fix the components will change first. The main bearing of the shield machine uses bolts to fix the components. When the main bearing tilts or internal failure occurs, the stress carried by the bolts will change. change. Under the action of cyclic load and forced vibration, bolts will appear fatigue damage and loosening, and the failure of bolts will cause catast...
