Problems solved by technology

Both the subway and the urban comprehensive pipe gallery are located in the city center or the suburbs. The previous open-cut construction has a great impact on traffic and the urban environment. The underground excavation method cannot be carried out or the construction efficiency is particularly low in most urban geological conditions. More and more subways and urban integrated pipe corridors are constructed using shield tunneling machine / TBM; shield tunneling tunneling machine / TBM construction has the characteristics of high construction efficiency, energy saving and environmental protection, and good safety. In a closed space, equipment failures cannot be judged intuitively. When a failure occurs, maintenance is difficult, affecting the construction period, and the cost is huge. Therefore, it is necessary to monitor the shield / TBM status online and grasp the shield / TBM status in real time.
Shield / TBM working parts are mainly mechanical parts, hydraulic parts and electrical parts. The existing monitoring methods can only monitor the mechanical and hydraulic parts, but cannot monitor the electrical parts, and they are all carried out offline. Keep abreast of the operation of the shield machine / TBM. Once the problem is not found in time, it will often bring huge economic losses. Therefore, online mechanical status monitoring for the shield machine / TBM can avoid the occurrence of some problems of the shield machine / TBM, and will not Affect the normal operation of shield / TBM equipment

Description

technical field [0001] The invention belongs to the technical field of equipment state monitoring, and in particular relates to a mechanical signal acquisition instrument for shield tunneling / TBM. Background technique [0002] Due to the comprehensive construction of domestic subways and urban comprehensive pipe corridors, the construction mileage is increasing year by year. Both the subway and the urban comprehensive pipe gallery are located in the city center or the suburbs. The previous open-cut construction has a great impact on traffic and the urban environment. The underground excavation method cannot be carried out or the construction efficiency is particularly low in most urban geological conditions. More and more subways and urban integrated pipe corridors are constructed using shield tunneling machine / TBM; shield tunneling tunneling machine / TBM construction has the characteristics of high construction efficiency, energy saving and environmental protection, and good...
