Self-propelled peeping probe adapted to different diameters of drill holes and peeping method thereof

Abstract

The invention discloses a self-propelled peeping probe adapted to different diameters of drill holes and a peeping method thereof. The probe comprises a peeping probe body, a camera, walking wheels, rocker arms connected to the walking wheels, and an operating host. The rock arms can achieve a certain angle of damping opening and closing under the effects of internal torsion springs and gas springs and have alarm functions, and the rocker arms can be fixed in grooves of a peeping probe side through locking holes and locking blocks. The self-propelled function of the peeping probe in a drill hole can be achieved through an internal power supply, a driving motor, a video processing module, a control module, a WIFI module and the external operating host. The peeping probe has the advantages of centered drill hole, self-propelling and less workers in operation in a drilling peeping operation process, the complexity in a conventional drilling peeping operation is reduced, a push rod and a video transmission line are removed, auxiliary accessories are greatly reduced, and a new solution is provided for determining the fracture of a rock mass through drilling peeping in underground engineering.

Description

technical field [0001] The invention relates to a peeping probe and a method, in particular to a peeping probe and a peeping method which are self-propelled and adaptable to different borehole diameters, and are suitable for the fields of geotechnical engineering, mining engineering and geological exploration. Background technique [0002] In geotechnical engineering, mining engineering, and geological exploration, the internal conditions of rock formations are relatively hidden, and it is difficult to find details such as cracks, separated layers, and broken areas inside rock formations through visual observation and empirical analogy. Based on this, engineers and technicians often use borehole peepers to detect the structure of rock formations in rock formations. In addition, the borehole peeping instrument can detect the range and changes of the surrounding rock loosening circle of the roadway, test the displacement change of the surrounding rock stratum during the stress...

AI Technical Summary

Problems solved by technology

[0004] However, under the background of the above process, there are the following problems: first, the advancing speed and range of the push rod are limited by manual operation, which may easily cause the image of key positions on the inner wall of the borehole to be unclear; second, when the drilling depth is large, the push rod The stability is difficult to control, especially during the peeking process of the roof drilling, the push rod is easily stuck by the broken rock blocks in the drilling fracture zone, which sometimes makes pushing difficult; third, it is difficult to center the peeping probe in the borehole, This leads to poor imaging accuracy, and the front edge of the peeping probe is easily scratched by the inner wall of the borehole, and debris is accumulated on the peeping probe, which deteriorates the imaging effect; fourth, the peeping process has strict requirements on the diameter of the borehole, and different diameters of boreholes need to be equipped with different diameters. Peeping probe, complex operation process, high equipment cost
