The utility model relates to a rig auxiliary device, concretely relates to a drilling rod stabilising arrangement for remote trompil, the device includes the extension frame parallel with the rig runway, and the perpendicular to extension frame place plane sets up the drilling rod support of extension frame one end, be equipped with fixed pipe on the drilling rod support, the axis of fixed hollow shaft line and holder or clinostat is on same straight line. The utility model provides a remote large -span when construction drilling because the unsettled distance of drilling rod is long, the rotatory amplitude of fluctuation that results in is big, so the trompil precision that causes is low, the drilling disability rate is high, the efficiency of construction lowly and easily take place the cracked technical problem of drilling rod.
