TBM carrying type test device and method for automatically obtaining rock slag particle size and strength characteristics

Abstract

The invention provides a TBM carrying type test device and method for automatically obtaining rock slag particle size and strength characteristics. The device comprises a telescopic mechanical gripperwhich is used for gripping rock slag and placing the rock slag into a rock slag fixing device; a rock slag fixing device, a rock slag cleaning device, a rock slag drying device, a rock slag photographing device, a point load testing device and a rock slag collecting device are sequentially arranged on a guide rail; the rock slag fixing device can freely move on the guide rail and is used for conveying rock slag to a preset position for corresponding operation; the rock slag cleaning device is used for cleaning rock slag; the rock slag drying device is used for drying rock slag; the rock slagphotographing device is used for collecting rock slag upper and lower surface images and transmitting the images to the data comprehensive processing system; the point load test device is used for fracturing rock slag and rock slag, collecting rock slag point load intensity and transmitting the rock slag point load intensity to the data comprehensive processing system. The data comprehensive processing system is used for obtaining rock slag characteristics such as the shape, the particle size and the point load strength index of rock slag so as to judge the rock mass change condition of the current tunneling surface according to the rock slag characteristics; the rock slag collecting device is used for collecting rock slag.

Description

technical field [0001] The invention belongs to the field of TBM-mounted test devices, in particular to a TBM-mounted type test device and method for automatically obtaining rock slag particle size and strength characteristics. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the large-scale construction of my country's infrastructure and the development of the western region, there will be a large number of tunnels to be built; the full-section tunnel boring machine (TBM) has the advantages of fast excavation, safety, economy, and small disturbance, so TBM is widely used in In the construction of long tunnels in my country; with the continuous changes in the characteristics of the rock mass in front of the tunneling face, it is necessary for the staff to adjust the corresponding TBM parameters in time to avoid accidents such as tool da...

AI Technical Summary

Problems solved by technology

[0004] Traditionally, the rock slag generated during TBM construction needs to be manually picked up on the conveyor belt, the rock slag is cleaned, the surface characteristics of the rock slag are observed with the naked eye, and the point load strength of the rock slag is obtained through a point load meter. The inventor found that the field operation The environment is complex, the dust concentration is high, and the belt conveyor runs at a high speed. It is difficult to manually pick up the rock slag that meets the test requirements on the conveyor belt, and it is unsafe.
