The specific embodiment
As depicted in figs. 1 and 2: a kind of falling protector and cage guide rope operation state monitored control system, it is characterized in that: this system comprises: Hydranlic tensioner 1, cage guide rope tensioning detecting sensor 2, fall prevention rope detecting sensor 4, sensor joint box, central control console, hydraulic control box, Hydraulic Station and winch control unit; Described Hydranlic tensioner 1 is fixed on the suitable position of derrick, and Hydranlic tensioner 1 blocks and upwards strain the cage guide rope 5 of lowering state; Described cage guide rope tensioning detecting sensor 2 is connected with Hydranlic tensioner 1; Described fall prevention rope detecting sensor 4 is installed in the below of anti-falling buffer device 3, and anti-falling buffer rope 6 is wrapped on the anti-falling buffer device 3;
Described cage guide rope tensioning detecting sensor 2 is connected with the fall prevention rope detecting sensor respectively and is connected with the acquisition of signal port of central control console by the sensor joint box, the signal output port of central control console is connected input end with the winch control unit respectively and is connected with hydraulic control box, the output port of hydraulic control box connects Hydranlic tensioner 1 by Hydraulic Station.
Described Hydranlic tensioner 1 is two telescopic hydraulic cylinders.
Described cage guide rope tensioning detecting sensor 2 is liquid-pressure pick-up.
The sensing element of described liquid-pressure pick-up is connected with hydraulic fluid port under two telescopic hydraulic cylinders.
Described fall prevention rope tensioning sensor 4 is pressure sensor.
The principle of work of this monitored control system is as follows:
As shown in Figure 3, Figure 4:
One, regulatory function: the maximum security value (s) that goes out every cage guide rope 5 tensile forces according to the calculation of parameter of each mine, regulate the charge oil pressure of Hydranlic tensioner 1 to setting value, make the cage guide rope tensioning reach optimum regime, guarantee the safe operation of mine vertical shaft hoisting cage.
Two, monitoring function:
1, cage guide rope tensioning detecting sensor 2 detects the oil pressure of Hydranlic tensioner 1 in good time, guarantees that the cage guide rope tensile force moves within maximum security value (s).
2, fall prevention rope detecting sensor 4 detects the end load numerical value of anti-falling buffer rope 6 in good time.
3, the signal of cage guide rope tensioning detecting sensor 2 and 4 collections of fall prevention rope detecting sensor is delivered to the acquisition of signal end of central control console, and central control console carries out the data analysis judgement by PLC wherein.Detection signal to pressure transformer and the conveying of monitoring sensor system is analyzed judgement, controls respectively the operation of winch control unit and hydraulic control box according to judged result.
The technological process of this monitored control system is as follows:
As shown in Figure 3: it is cage guide rope 5 tensile forces and the acquisition of signal end that signal is delivered to central control console by the sensor joint box that pressure transformer Y detects oil pressure, when if cage guide rope 5 tensile forces that pressure transformer Y detects are lower than setting value, central control console sends instruction at once to hydraulic control box, hydraulic control box starts Hydraulic Station after receiving signal, Hydraulic Station carries out ftercompction to setting value to two oil-cylinder hydraulic tensioning devices 1, makes the tensile force of cage guide rope 5 constantly keep optimal operational condition.
As shown in Figure 4, the J of monitoring sensor system detects anti-falling buffer rope 6 and signal is delivered to the acquisition of signal end of central control console by the sensor joint box, if spike appears in the anti-falling buffer rope 6 tensile force curves that the J of monitoring sensor system detects, and peak value is well beyond during initial value, the PLC that carries out data analysis in the central control console judges the catching device action thus, central control console sends instruction to the winch control unit at once, make winch out of service and report to the police, thereby avoid slack rope, the accidents such as card tank further reduce coal mine shaft lining cage hoisting security of system hidden danger.
