Power head guide rail device of heavy drill carriage

Abstract

The invention discloses a power head guide rail device of a heavy drill carriage. The device comprises a guide rail, wherein the tops on the left and right sides of the guide rail are provided with guide plates; the guide plates are cooperatively provided with a power head fixing frame; the power head fixing frame is provided with a base; oppositely arranged connecting blocks are arranged on the left and right sides of the bottom of the base; a bottom plate is welded between the two connecting blocks; the front end and the rear end of the bottom plate outwardly extend out of the base to form a T-shaped structure; side plates are arranged on the outer sides of the two connecting blocks; a pair of upper rollers and a pair of lower rollers are arranged on the inner sides of the front end and the rear end of the side plates; the upper rollers and the lower rollers are oppositely arranged and are in rolling connection with the tops and the bottoms of the guide plates respectively; the four corners of the bottom plate are provided with guide wheels; the guide wheels are in rolling connection with the outer side faces of the guide plates. The power head fixing frame is in rolling connection with the guide plates through the rollers which are arranged in the three directions of the tops, the bottoms and the outer sides of the guide plates; the section factor of the guide rail is large, the torsion resistance capacity is high, the stability during drilling can be guaranteed, and the device is mainly used for the heavy drill carriage.

Description

technical field [0001] The invention relates to the technical field of heavy-duty drilling rigs, in particular to a guide rail device for a power head of a heavy-duty drilling rig. Background technique [0002] At present, the traditional guide rail device of the power head of the heavy-duty drilling rig includes guide rails, guide plates are arranged on the tops of the left and right sides of the guide rails, and the power head mounting seats are slidably installed on the guide plates. The power head installation seat includes a connecting plate, the left and right sides of the bottom of the connecting plate are equipped with U-shaped gussets with openings inward, and the U-shaped gussets are slidably connected with the guide plate. The power head mounting seat of this traditional guide rail device is in rigid sliding contact with the guide rail, the guide rail is easy to wear, and the section coefficient of the guide rail is small, the torsion resistance is poor, and the d...
