Description

TECHNICAL FIELD

[0001] The utility model relates to a drilling rod lifting device technical field, concretely is a labor saving lifting device of exploration drilling rod. BACKGROUND

[0002] The exploration drilling rod is an important tool for geological exploration and mineral resources development. It is mainly made of seamless steel pipe and is used to connect the ground drilling machine and the drill bit at the bottom of the drilling equipment. Its main functions include transmitting power, conveying drilling fluid and mud, and lifting, lowering or rotating the bottom drilling equipment. After drilling, the drilling rod needs to be extracted and quickly and safely lifted from the hole to the ground, so a labor saving lifting device of exploration drilling rod is needed.

[0003] A geological drilling machine drilling rod labor saving lifting device is disclosed in Chinese patent No. CN214118107U, which includes a drilling machine tower, a pulley block at the top of the drilling machine tower, a steel wire rope wound around the outside of the pulley block, a driving element wound around one end of the steel wire rope away from the pulley block, and a cooperation between the pulley block composed of a double-track godet and a movable pulley, a steel wire rope, a clamp releaser, and a winch. When lifting the drilling rod, not only can the direction of the force be changed, but also the purpose of saving labor can be achieved. This not only reduces the wear and tear of the pulley, steel wire rope, and winch during the lifting of the drilling rod, but also enhances safety and reliability. It solves the problem that the existing lifting device can only change the direction of the force and cannot save labor. The force on the steel wire rope is large, which increases the wear and tear of the pulley, steel wire rope, and winch during the lifting of the drilling rod. The steel wire rope is prone to breakage and material consumption.

However, the lifting device used in existing engineering construction generally needs to be manually connected by the operator during the connection process, and the connection method is complicated, which increases the labor intensity of the workers and easily causes operational safety accidents. Therefore, we propose a labor saving lifting device of exploration drilling rod. UTILITY MODEL CONTENTS
