Downwards Transportation Belt Conveyor

Introduction:

The downward transportation belt conveyor is suitable for the transportation of underground troughs in coal mines, tunnels driving uphill, downhill centralized transportation lanes, main inclined shaft hoisting, open-pit coal mines and ground transportation systems. It is an ideal supporting equipment for coal mining mechanization.

Technological Difficulty:

The downward transportation belt conveyor is a special conveyor that transports materials from high to low. It has negative power during transportation of materials, and

the motor is in the state of power generation braking. It can effectively control the full-load start and stop of the belt conveyor, especially the controllable soft brake of the belt conveyor can be realized under the condition of sudden power loss. Preventing the belt conveyor from running way is the key technology of the downward belt conveyor.

Solution:

1. Adopting power generation operation mode the conveyor runs in the “zero power loss” state, and the excess power can also be used by other equipment.

2. Through the signal acquisition logic design, the system can not lose the logic design of the whole system after the cable is interrupted.

3. Adopting protection device design, a test network for the entire downward belt conveyor monitoring is built by a simple electrical switch.

4. The logic control of the emergency brake lock system ensures the safety and reliability of the conveyor under a large angle and high risk.

5. Long-distance signal stable acquisition anti-interference circuit design makes the transmission of long-distance acquisition signal reliable and fidelity.
