The specific embodiment
As depicted in figs. 1 and 2: a kind of falling protector and cage guide rope operation dynamic monitoring system, it is characterized in that: this system comprises: Hydranlic tensioner 1, cage guide rope tensioning detecting sensor 2, anti-fall 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 anti-fall rope detecting sensor 4 is installed in the below of anti-fall energy disperser 3, and anti-fall snub rope 6 is wrapped on the anti-fall energy disperser 3;
Described cage guide rope tensioning detecting sensor 2 is connected with the acquisition of signal port of central control console by the sensor joint box respectively with anti-fall rope detecting sensor 4, the signal output port of central control console is connected with the input end of winch control unit and hydraulic control box respectively, and 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 a 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 anti-fall rope tensioning sensor 4 is a 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, the charge oil pressure of regulating Hydranlic tensioner 1 is 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, anti-fall rope detecting sensor 4 detects the end load numerical value of anti-fall snub rope 6 in good time.
