Embodiment 2

[0027] Embodiment 2, a full-state real-time online monitoring system for a TBM hob, two strain gauges 3 are provided, and the two strain gauges 3 are vertically arranged in the support wedge 53, and the strain gauges 3 pass through The profile block 56 is arranged tightly within the support wedge 53 . Setting two strain gauges perpendicular to each other can monitor the force of the TBM hob in the longitudinal and transverse directions, making the monitoring data more accurate and reliable.

[0028] Further, the strain gauge 3 is provided with a thermocouple 31 for monitoring the temperature of the TBM hob, and the thermocouple 31 is connected to a signal processing unit 41 . Set the thermocouple to work with strain gauges, inductive sensors, and Hall elements, and can simultaneously monitor the four index parameters of TBM hob wear, TBM hob speed, TBM hob force, and TBM hob operating temperature, so that the detection effect can be improved. More precise and reliable. Other...

Embodiment 3

[0029] Embodiment 3, a full-state real-time online monitoring system for a TBM hob, the base is provided with a protective cushion 21 for preventing the Hall element 2 from getting wet and vibrating, the protective cushion 21 is made of AB glue, and the Hall The outer end of the element 2 is provided with a non-magnetic titanium alloy end cap 22 . Setting a protective pad behind the Hall element can effectively protect the Hall element from damage, and at the same time reduce the vibration amplitude of the Hall element, which can ensure the reliability of the TBM hob speed measurement; the non-magnetic titanium alloy end cover The setting not only plays the role of collision protection, but also can effectively avoid the inaccurate influence of magnetic metal on the Hall element.

[0030] Further, the sensor base 4 is provided with a positioning sleeve 46, the inductive sensor 1 is arranged in the positioning sleeve 46, the outer end of the inductive sensor 1 is provided with ...

Abstract

The invention discloses a TBM hob full-state real-time on-line monitoring system and a measurement method thereof. The system comprises an inductive sensor, a Hall component, a strain gauge and a sensor base. The inductive sensor and the Hall component are arranged in the sensor base. The inductive sensor corresponds to a cutter ring of a TBM hob. The TBM hob is provided with a magnetic block which is opposite to the Hall component. A shaft hole of the TBM hob is provided with a support wedge block and a tensioning wedge block. The strain gauge is arranged in the support wedge block. A signalprocessing unit is arranged in the sensor base. The inductive sensor, the Hall component and the strain gauge are connected to the signal processing unit. The signal processing unit is connected to aTBM upper computer through a wireless communication module. In the invention, four index parameters of an abrasion loss of the TBM hob, a rotation speed of the TBM hob, a stress of the TBM hob and a working temperature of the TBM hob can be monitored; and through real-time monitoring, a working state of the TBM hob can be timely controlled and a damaged condition of the TBM hob can be timely knownso that the TBM hob can be timely repaired or replaced.

Description

technical field [0001] The invention relates to the field of TBM hob monitoring, in particular to a TBM hob full-state real-time on-line monitoring system and a measurement method thereof. Background technique [0002] As a large-scale construction machinery, TBM has a harsh working environment and a complex and huge system. Any problem in any part may cause the system to shut down, resulting in a greatly reduced construction efficiency. The TBM tool is the direct implementer of the TBM's forward tunneling, and it is extremely easy to wear and tear. The amount of tool wear directly affects the construction efficiency and indirectly increases the construction cost. According to the past construction situation, in the time-consuming work of TBM, the inspection and excessive wear of the tool lead to unexpected downtime of the equipment, the replacement and maintenance of the time and cost are about 30% of the overall project. Therefore, it is necessary to monitor the overall ...
