One end of a rack is provided with a Hall sensor a, a Hall sensor b and a Hall sensor c, and a proper distance is arranged among the three Hall sensors, and between the Hall sensor and an adhesive tape. A wireless force cell is disposed at the center position of the bandwidth direction of two ends of the conveyer belt joint area. A supporting device is welded to a conveyor truss, and a Hall element is fixed on the supporting device. The wireless force cell is preembedded in the center position of the bandwidth direction of the conveyor belt joint area. A drive roller, a direction change roller and a hydraulic loading device are disposed on a fixed test-bed and are connected to the conveyer belt. The utility model is advantageous in that the device simulates the dynamic characteristic of the conveyer belt joint at the time of running; the measure curve accords with a real curve; the measuring device is simple; the dynamic characteristic curve of the tension force and length of the conveyer belt joint is determined; the reliability is high, the capability of interference resistance and environmental adaptation is strong.
Description
Technical field
The utility model relates to the wire cable rupture monitoring device, specifically a kind of performance graph determinator of steel cable core conveying belt joint.
Background technology
Present stage, the method for conveying band joint fracture monitoring has in the conveyer of producing and using: one, simple and easy joint distortion detection method, normally according to on-the-spot experience and concrete condition of service, reliability is not high for the setting of deflection threshold value for the method.The on-line monitoring that can't be used for joint breaking.Two, magnetic image analytic method, the failure analysis of this monitoring method and diagnostic technology are complicated, and calculated amount is very big, and its diagnotic accuracy, reliability and real-time still have much room for improvement.Three, X ray is surveyed monitoring method, and the shortcoming of this method is: the equipment complexity, install inconvenient, antijamming capability is weak, reliability is not high, X ray has infringement etc. to human body.Four, based on the artificial neural net (ANN) diagnostic method of image processing techniques, owing to video tape recorder, optical system, image transmission route etc. partly carry out heavy line service, but also very easily impaired, finally this measuring system can't carry out on-line measurement.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of curve dynamic measurement device of steel cable core conveying belt joint is provided, the technical scheme that its technical matters that solves the utility model adopts is: structure of the present utility model comprises magnet, wireless force transducer, Hall element a, head roll, joint area, loading system, the changed course cylinder, load-transfer device, Hall element b, Hall element c, frame, it is characterized in that magnet be arranged on load-transfer device joint area two ends bandwidth direction about each 1/4th place, Hall element a, b, keep suitable spacing between the c three and between they and the adhesive tape, wireless force transducer is arranged on the center of two ends, conveying band joint zone bandwidth direction, head roll is connected with load-transfer device, load-transfer device is connected with the changed course cylinder, the changed course cylinder is connected with loading system, determine the experimental technique of conveying band joint " F-L " (tension force-length) dynamic characteristic: at first at the initial tension F0 of conveying band joint and the minimum working load tension force F1 of joint, get some values between the maximum load Fmax when reeling off raw silk from cocoons appears in minimum working load tension force F1 and maximum working load tension force F2 and maximum working load tension force F2 and joint, utilize the hydraulic loading system butt junction in conveying band joint " F-L " (tension force-length) the dynamic characteristic determinator to load, little magnetic patch as test point in the device sends signal through Hall element, utilize this signal to measure a series of length of joint area, the power that wireless force transducer is measured is corresponding one by one with the length of joint area, utilize methods of numerical to carry out curve fitting, promptly obtain this kind conveying band joint " F-L " (tension force-length) dynamic characteristic.Wherein, the initial tension F0 of conveying band joint is 0, the minimum of joint and maximum working load tension force F1, F2 are provided by the concrete operating mode that load-transfer device uses, joint initial length L0 is by measuring, maximum working load Fmax when reeling off raw silk from cocoons appears in joint, o'clock begin to occur part steel cable core wire drawing because joint reaches 75% of its Breaking load～85% at tensile force usually, thereby the maximum allowable tension force Fmax that can set joint is 75% of its Breaking load F '.For safety, factors such as the increment load of considering that the joint sulfuration process is undesirable, joint is crooked, producing after the grooving and the joint fatigue damage of long-term use and aging, installation, select its theoretic minimum value divided by 3 safety factor, so the maximum working load Fmax of joint when occurring reeling off raw silk from cocoons can be drawn by following formula:
Fmax=75%F '=75%F
Original tapeη/3=F
Original tapeη 25%.
The beneficial effects of the utility model are, this device real simulation conveying band joint in the dynamic characteristics in when operation, the curve of surveying meet with true curve, and experimental set-up is simple, determined conveying band joint " F-L " (tension force-length) dynamic characteristic, for the real-time monitoring and the trouble diagnosing of conveying band joint fracture proposed foundation, overcome the defective that existing conveying band joint fracture monitoring method can not on-line monitoring.
