Abstract
The utility model discloses a pulley support for installing a drilling rod. The pulley support comprises two pulley installing plates which are arranged in a left-right parallel mode. At least two groups of corresponding pulley installing holes are arranged in the two pulley installing plates. Vertically limiting sleeves are arranged on outer walls of the two pulley installing plates. In order to facilitate installing pulleys, each pulley installing plate is composed of a front clamping plate and a rear clamping plate. Each front clamping plate and each rear clamping plate are connected via screws or dowels. Front half portions of the installing holes are formed in front clamping plates. Rear half portions of the installing holes are formed in rear clamping plates. The pulley support for installing the drilling rod has following beneficial effects: a stretching steel rope of the drilling rod is well limited and cannot swing or distort so that smooothness of the stretching steel rope is substantially improved.
