Product Description

Sliding-down-proof Device Brief Introduction 

Sliding-down-proof Device mainly in coal mines, metal mines and nonmetal mines all inoue or borehole inclination in 30 degrees of single or double rail transport inclined which use.

This product meets the "Coal Mine Safety Regulations" on page 370: "In the inclined roadway within outages must be able to install rope, decoupled from the vehicle to stop living proof car device", "block car devices must be kept closed, shall be allowed to put the car open "," doubles as a roadway inclination of people and vehicles traveling in upgrading personnel, the tilt of the cars blocked roadway devices and anti-car devices must be normally open state, and reliably "lock" requirement.  

Sliding-down-proof Device Features 

1.function powerful, easy to control

2.system control and high precision, high reliability

3.the flexible buffer technology, product cost-effective, system components easy to installation, maintenance is simple, stable performance, high performance/price ratio, and integrated. 

Sliding-down-proof Device Working Principle 

The device supply chain interaction with the winch, winch that is energized, the device is powered job; winch off, the device stops working. This device is powered up, the system automatically detects real-time position since tramcar block car field whether decentralization in place, fault indication. 

When the tub normal downlink, stop bar is normally closed state, the tub down to the PLC set first set value, the master PLC will control the auto-complete l bar lift motor operation; tub reaches the second set value when completed master PLC will control the motor down bar, recovery normally closed. When the tub up to a second set normal value, automatically lowering column, recovery normally closed. When the tub normal upward to reach the second set value, PLC control mention Landang car; carts to reach the first set value, the auto-complete drop bar, recovery normally closed state. When the tub beyond the normal speed (sports, coasting) when, PLC control buffered block car column of the tub for reliable block, thereby effectively avoiding accidents.

For multi-point multi-block car sports car protection, PLC serial communication, greatly reducing the signal cable, easy to control, simple installation, winch room centralized control display box can also be timely and accurately reflect and controls each block car bodies and the work of the tub .
