Product Details

In the lifting system of vertical shaft mine, the lifting skip is guided by 2 or 4 steel wire ropes in the process of up and down lifting, the upper end is fixed on the derrick and the lower end is fixed on the bottom of the shaft. According to the requirements of safety regulations for metal and nonmetal mines: the sealed steel wire rope shall be preferred for the steel wire rope tank way, the minimum rigidity coefficient of each tank way rope shall not be less than 500N / m, the tension of each tank way rope shall be 5% - 10%, the tension on the inner side is large, and the tension on the outer side is small. This requires that the tank way rope has sufficient tension and accurate value. At present, there are mainly two ways to adjust the tension of the guide rope, which are hydraulic screw and heavy hammer. The former installation is not convenient and the tension is easy to reduce. The latter requires a deep well bottom water pit, which is easy to be accumulated by falling debris, the position of tank track rope is easy to shift, the tension value of tank track rope is inaccurate and the investment cost is large. The tension of the tank way rope cannot be accurately detected and adjusted, and the later tension value can not be found and adjusted in time, which brings great hidden dangers to the lifting safety.

As-gsz tank way rope centralized control system is an automatic device for on-line real-time detection and adjustment of tank way rope developed to overcome the shortcomings of existing tensioning technology. The centralized control system consists of five parts: tank track rope tensioning device, force measuring sensor assembly, PLC data acquisition, analysis center, centralized control hydraulic station and remote control system. The steel wire rope of the tank way is fixed and locked in the tank way rope tensioning device. When the tank way rope is tensioned, the remote control system controls the centralized control hydraulic station to start. The tank way rope is gradually tensioned under the action of the tensioning device. The load cell assembly placed on the base of the tank way rope tensioning device starts data acquisition under the pressure of the tank way rope tensioning device. The collected force data is converted into electrical signals and transmitted to the PLC data acquisition and Analysis Center, and the data is analyzed. The remote control system displays the processing value and evaluation results, early warning the tension and realize human-computer interaction.

Product features:

1. PLC program, intelligent data analysis, industrial touch screen display, measured value and control, remote operation;

2. Equipped with remote video monitoring to understand the working position of tensioning device in real time;

3. Real time monitoring: the rope tension value of each tank way is displayed in real time, with high and low risk values. When the tension is abnormal, the alarm can be given to prevent potential safety hazards and ensure safe production;

4. After adjusting the tension value, the driving oil cylinder is not stressed, the rope locking device is stressed and locked reliably, and the service life of the hydraulic oil cylinder is long;

5. When the tension of the tank way rope is adjusted, the hydraulic station is started to avoid the loss of long-term operation of the hydraulic station.

Figure 2: detection screen

(1) display part

Signal lights: respectively indicate that the oil pump motor of the hydraulic station is overloaded (red flashing); Hydraulic failure (red flashing); Stop signal (red light on); Oil pump running (red light on); The upper and lower limits of the tension of the tank track rope alarm and the sensor fault alarm (the red light is on). Data area: it represents the measured value and standard value of each tank track rope respectively

(2) button part

① "Start pump" and "stop pump" respectively control the start and stop of the oil pump motor in the hydraulic station.

② "Reset" is used to reset the stop signal triggered when the tension of any tank track rope exceeds the upper and lower limits.

The buttons in the "adjustment screen" box respectively control the adjustment screen of the tension of each tank track rope. Click the corresponding button to enter the tension adjustment screen of this rope, as shown in Figure 3;

"Tension setting screen": set the parameter values of the tension of the tank rope, as shown in Figure 4; "Return to home page": return to the home page screen of startup.


Figure 3: tension adjustment screen


Figure 4: tension setting screen

Set the upper and lower limit values, upper and lower limit values and set values of the skip tank rope in Figure 4. Click the green area in the figure and enter the user name and password to manually adjust the value. The value range is 0 ~ 10 (taking 10 tons as an example). The safety management authority function of the green data setting area in this figure is the same as the standard value safety management authority function in Figure 2. When the measured value is greater than the upper limit but less than the upper limit, the upper limit alarm is carried out (the upper limit alarm light in the detection screen is red); When the measured value is less than the lower limit but greater than the lower limit, the lower limit alarm is carried out (the lower limit alarm light in the detection screen is red); When the measured value is greater than the upper limit or less than the lower limit, the stop signal is output (the stop signal light in the detection screen and the corresponding tank Lane rope are red) and the winch stops. When the tension of the West 1# rope needs to be adjusted, first start the oil pump in the detection screen, and then click the "West 1#" button in the adjustment screen box to enter the screen shown in Figure 3. At this time, just press and hold the green button, and the measured value of the tank rope of this rope number will increase. At the same time, pay attention to the oil pressure value of the hydraulic station. When the measured value is greater than or equal to the set value, the system will automatically stop the oil pump, The rope has been adjusted; Other ropes are also adjusted accordingly. Click the "return" button to return to the detection screen.
