Overview
The JKZ series well-drilling hoists are key pieces of equipment specifically designed for wellbore excavation operations in coal mines, metal mines, and non-metallic mines. They are primarily used to hoist buckets, transport personnel, raise various well-drilling machinery and equipment, and lower concrete for wall construction. The structural configuration of this series of hoists is similar to that of winding-type hoists, yet it offers superior lifting capacity. It typically consists of a main shaft assembly, a drum brake assembly, a drum liner, a hydraulic station, a depth indicator and transmission assembly, a speed-measuring transmission assembly, a lubrication station, a gear coupling, a reducer, an elastic rod pin coupling, a motor, and various base units. With a wide range of specifications and models, these hoists can be adapted to the operational requirements of different well depths and wellbore diameters; throughout the entire well construction process, they play a critical role in ensuring the safety of lifting operations and improving the efficiency of well construction.
Operational Principle
This product comprises the power system, transmission system, operating system, braking system, control and operation system, indication and protection system, and their associated components.It uses an electric motor as its power source; through a planetary reduction gear and a main shaft assembly, it forms the product’s highly efficient transmission and operating systems; a hydraulic station and braking device provide its reliable braking system; a control console and electrical control equipment constitute its comprehensive control and operation system; and a depth indicator, tachogenerator, and other components form its complete indication and protection system.
