Background technology
In existing vertical shaft for mine, the flexible guide rail of existing flexible cage guide is applied in mine hoisting system at present.Along with continuing to increase of the mine degree of depth, the advantage of flexible cage guide is further obvious.The tension force of cage guide rope has reacted the important running state information of wire rope and relevant device." safety regulations in coal mine " the 388th article regulation: " when each hoisting conveyance has 4 cage guide rope; the minimum rigidity coefficient of every root cage guide must not be less than 500N/m; the difference of the tension force of each cage guide rope must not be less than 5% of mean tension, and inner side tension power is large, and outside tensile force is little; Each hoisting conveyance only has two cage guide rope, and the minimum rigidity coefficient of every root cage guide must not be less than 1000N/m, and the tensile force of each rope should be equal." for ensureing the work that elevator system is safe and reliable, tension force and the stiffness coefficient of correct measurement cage guide rope are necessary.
The main method of current steel wire rope tension detection has three kinds: one to be series process, and its principle carrys out measuring steel wire rope tension for a force cell of connecting between wire rope with lifting heavy; Two is three-point bending methods, realizes steel wire rope tension measure according to the composition and decomposition principle of power; Three is inductance methods, causes wirerope diameter size variation thus make the change of the inductance value in inductive coil by steel wire rope tension change, obtains steel wire rope tension by analyzing.It is low to there is measuring accuracy in these methods, and process is complicated, installs inconvenience or destroys the shortcomings such as wire rope globality.
Summary of the invention
Technical matters: the purpose of this utility model is the weak point overcome in prior art, provides a kind of structure is simple, easy for installation, measuring accuracy is high tension of cage guide rope pick-up unit and method.
Technical scheme: mine cage guide rope tension pick-up unit of the present utility model, comprises wireless receiving module, notebook computer, and also comprise the wireless measurement instrument be located in cage guide rope, described wireless receiving module is connected with notebook computer through communication cable; Described wireless measurement instrument comprises armored cassette and gain antenna, is provided with the acceleration transducer, signal acquisition module, wireless transmitter module and the power module that connect successively in armored cassette.
Described wireless measurement instrument is fixed in cage guide rope through bandage; Described wireless measurement instrument outside is provided with armored cassette.
Beneficial effect: owing to have employed technique scheme, the utility model has the following advantages:
(1) device volume is little, easily installs, easy to use: wireless measurement instrument volume is little, and built-in power module, utilizes wireless transmission, and antijamming capability is strong, without complicated wiring, and flexible arrangement; Adopt the shell of armored cassette, meet safety regulations in coal mine; Utilize bandage to be fixed in tested cage guide rope, be applicable to the cage guide rope of various diameter, easy accessibility.
(2) detection method is simple, precision is high: utilize the relation between tension of cage guide rope and row velocity of wave propagation to realize the detection to tension of cage guide rope, by the mistiming between the peak value that detects cage guide rope transverse acceleration, obtain the propagation cycle of ripple in cage guide rope of shaking, according to line density and the cage guide rope length of known parameter cage guide rope, can calculate tested tension of cage guide rope and stiffness coefficient, testing result precision is high, and method is simple and reliable.
