JKM/JKMD multi-rope mine hoist

Core Structure and Design Features

Main Shaft Device:

The friction wheel adopts a welded structure of Q355 high-strength low-alloy steel. The friction linings are clamped by fixing blocks and fixing pressure blocks, which are fixed on the friction wheel. It is connected to the main shaft through a double-flange, double-clamp plate, and double-sided planar friction joint, which transmits torque through the friction force between the two clamp plates and the main shaft of the friction wheel. Double-row self-aligning roller bearings are configured at both ends. The transmission efficiency is ≥90%.

Brake System:

Disc Brake: Designed with a rear-mounted cylinder, the braking force is provided by disc springs and driven by a hydraulic station (response time <0.3 seconds). The braking torque is ≥3 times the maximum static torque. It supports secondary braking and electro-hydraulic proportional adjustment, and automatically triggers safety braking when power is cut off.

Transmission System:

Reducer: Optional planetary gear or cylindrical gear reducer, with a hardened tooth surface design (material: 20CrMnTi carburized and quenched), featuring stable transmission and low noise.

Speed Regulation System: Supports variable frequency speed regulation (energy saving of over 30%) or resistance speed regulation, compatible with PLC control to achieve remote monitoring.

Technical features

Real-time Monitoring: Integrate sensors for overspeed, overwinding, rope slack, brake wear, spring fatigue, etc., and interlock with the main motor for control.

Dual Depth Indicators: Combination of mechanical type and digital type, with positioning accuracy error <0.5m.

Emergency Mechanism: Redundant design for power-off automatic braking, shaft breakage protection, and emergency braking, complying with GB 16423 safety regulations.

Product Application

Applicable scenarios:Multi-rope friction hoists are applicable to vertical shafts in coal mines or metal mines, serving as both main shaft hoisting and auxiliary shaft hoisting. They can be used in double skip-double cage hoisting systems and single-container hoisting systems with balance weights.

Usage Limitations:The double-container hoisting system is only suitable for single-level hoisting; the single-container hoisting system with a balance weight can be used for multi-level hoisting
