Abstract

The invention relates to a test system and a test method capable of being used for testing the positive pressure on the cutter ring and cutter body matching surface in the hobbing cutter hobbing rockbreaking process in real time. The system comprises a digital collecting instrument, a hobbing cutter, an electric eddy current displacement sensor, an industrial computer and a pressure sensor, wherein the groove is locally formed in the matching surface of the cutter ring and/or the cutter body, so that a space gap for accommodating the pressure sensing region of the pressure sensor is formed inthe matching surface; one surface of the pressure sensing region is fixedly connected with one surface of the space gap; in the initial stable state, the pressure sensing region has a given tiny initial vertical extrusion deformation quantity Delta 0; the digital collection instrument can collect the output signals of a three-direction force sensor, a pressure sensor and an electric eddy currentdisplacement sensor in real time and transmits the signals to the industrial computer. The test system and the test method solve the problem of limitation of real-time monitoring measurement difficulty of the positive pressure on the cutter ring and cutter body matching surface during the hobbing cutter hobbing rock breaking.

Description

technical field [0001] The invention belongs to the intersection field of full-section tunnel boring machine technology, signal analysis and processing technology and rock crushing, and relates to a positive pressure test system and a test method on the mating surface of a disc-shaped hob cutter ring cutter body, in particular to a test method capable of A test system and a test method for real-time monitoring of the positive pressure on the mating surface of the cutter body of the cutter ring during the rock-breaking process of the disc-shaped cutter. Background technique [0002] Since the 21st century, with the rapid development of my country's economy and the continuous improvement of the level of urbanization, the available space on the ground has become less and less, and strengthening the development and utilization of underground space has become an inevitable trend of today's urbanization and urban modernization. In the excavation process of underground space tunnel...
