Abstract

The invention belongs to the technical field of shield construction engineering and relates to a shield construction soil discharge quantity real-time on-line measuring device based on a pin wheel device. The shield construction soil discharge quantity real-time on-line measuring device comprises the pin wheel device, wherein the pin wheel device is arranged at the soil outlet part of a spiral conveyer of a shield machine and is arranged in a plane vertical to the residue soil direction. The pin wheel device comprises a pin wheel, a pin wheel shaft, a left box body, a right box body and a shaft coupler, and the pin wheel shaft is connected with a rotary encoder through the shaft coupler. A control part is used for carrying out storage, preprocessing, integrating and display operation on original data, the cross section value of the soil outlet is integrated with the output speed of the rotary encoder by software, and the soil discharge quantity volume is obtained. The measuring device is applicable to conditions that the shield machine passes through humid soil layers with a certain viscosity, and the outlet soil of the spiral conveyor can form humid column bodies with a certain viscosity, the accurate and real-time measurement of the soil discharge volume is realized, the precision and the real-time performance of the original measuring method is improved, and the shield construction requirements are met.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling construction engineering, and specifically relates to a pin wheel device for measuring the amount of soil displacement in shield tunnel construction and an online real-time measuring device composed of the pin wheel. Background technique [0002] The authorized announcement number of Sichuan Runzhixing Technology Co., Ltd. is CN201852847U, a utility model patent "speed measuring and positioning device for moving objects", which is mainly composed of a data processor, a rotary encoder, and a synchronization mechanism.
