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.

Abstract

The invention provides a TBM-mounted type automatic acquisition rock slag particle size and strength characteristic test device and method. The device includes a retractable mechanical gripper for grabbing rock slag and putting it into a rock slag fixing device; a rock slag fixing device, a rock slag cleaning device, a rock slag drying device, and a rock slag photographing device are sequentially arranged on the guide rail , point load test device and slag collection device; slag fixing device can move freely on the guide rail, used to transport slag to the preset position for corresponding operation; slag cleaning device is used to clean slag; slag drying The device is used to dry rock slag; the rock slag camera device is used to collect images of the upper and lower surfaces of rock slag and transmit them to the comprehensive data processing system; Send to the data comprehensive processing system; the data comprehensive processing system is used to obtain the rock slag characteristics such as the shape, particle size and point load intensity index of the rock slag, so as to judge the change of the rock mass at the current excavation face according to the rock slag characteristics; rock slag collection The device is used to collect 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...
