Abstract

The invention discloses a rotary drilling rig and a power head carriage thereof. The power head carriage of the rotary drilling rig comprises a carriage body, an oil cylinder seat plate is fixed at the top of the carriage body, a detachable lifting pulley is mounted on the upper portion of the carriage body, and a detachable lay-down pulley is mounted on the lower portion of the carriage body. The oil cylinder seat plate used for fixing a pressurizing oil cylinder is arranged on the carriage body and the detachable lifting pulley and lay-down pulley are mounted, so that the carriage has a double-pressurizing structure and can pressurize by the pressurizing oil cylinder and a pressurizing steel wire rope as well, and the rotary drilling rig is multifunctional, applicable to pressurizing of carriages of various rotary drilling rigs and wide in application range.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a power head carriage of a rotary drilling rig and the rotary drilling rig. Background technique [0002] At present, the rotary drilling rig is a construction machine used for forming holes in building foundation engineering, and it is more and more widely used in the hole-forming construction of pile foundations. The use of rotary drilling rigs in engineering not only reduces the labor intensity of traditional manual operations, but also improves construction efficiency. The power head is an important part of the rotary drilling rig, providing torque for the drilling of the rig. The power unit of the rotary drilling rig includes: hydraulic motor, gearbox, reducer, carriage, connecting plate, etc. [0003] The slide frame is equipped with a pressurized pulley and a pulling pulley, and the wire rope realizes the pressurization and pulling action of the power head ...
