Description

Centering adjusting device for drilling peeking

Technical Field

The invention relates to the technical field of auxiliary equipment of a drilling television probe, in particular to a centering adjusting device for drilling peeking.

Background

In the field of coal mines, a drilling peeping instrument is used for monitoring a coal seam structure, a geological structure and the like, in the drilling process, drill rod connection and drill rod disassembly operations are inevitably needed, however, the operations are carried out manually at present, and the efficiency is low. And due to the unevenness of the drilled hole, the probe cannot be kept in a centered state all the time, and an ideal peeping panoramic picture cannot be obtained. Therefore, there is a need for a device for automatically connecting and disconnecting the rod and adjusting the position of the probe in time to the center position facing the uneven rock wall surface.

The patent number 202010223016.4 entitled "auxiliary centering device for variable-diameter borehole television probe" discloses: can overlap the lantern ring of locating borehole television probe, wear to be equipped with three can follow its radial flexible extensible member on the global of the lantern ring, can guarantee borehole television probe and keep balanced gesture placed in the middle in drilling always, can not paste the drilling wall, can obtain stable image. However, the distance between the collar and the rock wall is too large in the scheme, when the pushing rod pushes inwards, if a protruding rock wall with a radius between the distance between the collar and the rock wall is encountered, the problem cannot be found in time, and the position condition of a raised barrier on the wall of the hole cannot be grasped in time. Secondly, the pulley that uses in this scheme realizes all-round rotation for current universal wheel, but when the probe was advancing, because the pore wall is irregular, leads to whole rocking easily, and the effect of peeping is relatively poor.

In order to solve the problems, the scheme is developed accordingly.
