Explosion-proof hoisting equipment in the JTP series, specifically designed for environments with gas and coal dust explosion risks, such as underground coal mines. Its core feature is to achieve "intrinsically safe explosion protection". It strictly complies with explosion-proof standards to ensure safe and reliable operation in flammable and explosive environments, making it a key piece of equipment for material hoisting in underground coal mines.
Structure Features & Working Principle:
The equipment is centered on "explosion-proof safety" forms an intelligently coordinated closed-loop working system:
Intelligent Control: The flameproof electric control system receives and processes commands.
Power Execution: The flameproof motor is started, which drives the drum after torque increase via the reducer.
Hoisting Operation: The drum winds and unwinds the steel wire rope to realize the lifting and lowering of the container.
Full-process Monitoring: The depth indicator feeds back the position and speed to the electric control system in real time.
Safe Braking: When stopping is required, the electric control system commands the hydraulic station to control the disc brake for braking.
Emergency Protection: The electric control system is equipped with multiple protections and will trigger emergency braking immediately in case of abnormality.
Professional Explosion-proof: Designed specifically for high-risk explosive environments, eliminating electrical ignition sources at the source.
Dual Safety Protection: Combines mechanical braking (disc brake) with intelligent electronic control protection to form a redundant safety barrier.
Reliable and Efficient: electronic control system ensures precise and convenient operation, overall design guarantees stable operation under harsh working conditions.
