Common electric control system for mine hoist hoist (machine)

Product purposes

Technical skills

1. According to the improvement process control

requirements and signal instructions issued by the signal

system, control the start-up, operation, deceleration, stop

and other processes of the hoist, running smoothly and

reliably.

2. Meet the requirements of control process of elevator and

various safety chain protection requirements.

3. Realize the travel monitoring of the hoist, with perfect

depth and speed display control function.

4. Realize the requirement of vacuum and non-contact of the

control device of the main loop control device, the hardware

configuration is simple, the software programming is flexible,

the debugging is convenient and the maintenance quantity is

small. The system has good dynamic performance and good

performance.

5.Improve the mine chance the safety reliability and control

technology, to reduce equipment failure rate, improve the

production efficiency, reduce the labor intensity of operators play an important role.

 

Safety protection and chain function

The safety loop locks up the operation condition of the hoist

only when the external equipment runs normally and has the

driving condition. The safety loop locks the whole fault

protection signal of the hoist. Once the failure occurs, the

hoist is immediately put on the emergency brake.

 

Comprehensive backup protection function

1, using proximity switch on the operation of the hoist speed

machine position of digital detection and control, improve

the system control precision and reliability, and speed

generator is used to detect the speed, has the hardware

protection.

2. The double loop of the safety circuit, the system has at

least the software security loop, the hardware security loop.

Implement lifting machine multiple protection.

3. Automatic transmission of position signals, such as

deceleration, parking, overwinding signal, etc., important

points such as deceleration, overvolume and so on, at

least two or more roads together.

4. Have the protection of the depth indicator failure

protection, operation direction error protection, loose rope

protection, lock protection, speed limit protection, and up

and down protection
