Abstract

The invention relates to a rotary power head, in particular to a high-torque double-motor double-speed rotating power head, and belongs to the technical field of the drilling power head device. The rotating power head comprises a power box, the power box has a spline shaft in the center, and hydraulic motors are connected with one end of gear shafts on the left and right sides of the spline shaft, and drive the gear shafts. The hydraulic motors on the left and right sides of the spline shaft are connected to a hydraulic motor control handle via a hydraulic motor control assembly which can control the two hydraulic motors to operate independently or simultaneously. The high-torque double-motor double-speed rotating power head has the advantages of simple, compact and reasonable structure, and has the hydraulic and mechanical double shifting and many shift gears so that the rotary speed range is wide and suitable for various use conditions. The self-lubricating mechanism prolongs the life of the gear and the bearing, and the driving torque of the double motor is greatly increased.

Description

technical field [0001] The invention relates to a rotary power head, specifically a high-torque double-motor double-speed rotary power head, which belongs to the technical field of drilling rig power head equipment. Background technique [0002] At present, domestic fully hydraulic power head drilling rigs generally use single-speed power heads, including hydraulic single-speed power heads and mechanical single-speed power heads. When the power head is working, the turning torque becomes larger, and the turning speed becomes smaller; the turning speed becomes higher, and the turning torque becomes smaller. The internal gear of the power head is severely worn, and the bearing is easily damaged, especially when the down-the-hole hammer is drilled, and the drill pipe thread is easily damaged when the drill pipe is unloaded. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a high-torque dual-moto...
