Abstract
The invention relates to a measure and display apparatus of rope stress, especially relates to a measure and display apparatus suitable for measuring the stress of a strapping or an elevator belt, comprising rope positioning shaft pins(2) arranged on a structure pedestal(5) and a sensor (4) with a middle projection; the interior of the structure pedestal(5) is equipped with a cavity(3); the two rope positioning shaft pins(2) are arranged at the two sides of the sensor (4) respectively, and are in mutual parallel with the middle projection of the sensor (4); the sensor (4) is connected with a microcontroller via a signal conditioning circuit; and the microcontroller is also connected with a digital display. The effects of the invention are that by transforming the rope stress into an electronic signal via the sensor, and arranging by the signal conditioning circuit, after that, inputting into the microcontroller, and then, displaying on the digital display, the measure and display apparatus of rope stress is not only convenient in usage, simple in operation and fast in reading, but also very accurate in measure data.
Description
Technical field
The present invention relates to a kind of rope band stress measurement and display device, relate in particular to a kind of stress measurement and display device of measuring strapping or elevator belt that be applicable to.
Background technology
At present, the measurement of known rope band stress and display device are a kind of forms of the wedge rope_ring that opens wide or seal, and the stress of rope band can be by transformable range observation and the demonstration between the side arm end of spring.Measurement mechanism is around the tension pivot pin of the collar inside that is arranged on rope band, and its principle of work is: when measured object was subjected to stress, the collar angle that is looped around the tension pivot pin changed the distance between the side arm end at measurement mechanism two ends.
But known measurement and display device are to measure the gamut of load, therefore the spring of such measurement mechanism must be measured very little acting force and very big acting force, and in the present instrument in order for example to measure the minimum force that occurs when the prestress, correspondingly need a weak spring, but it must bear very big pulling force again, change of shape can take place in weak spring when overload, thereby wrong demonstration stress, even adopt restraint device to guarantee that weak spring can not transship, such device yet exists reading difficulty, the defective that measuring accuracy is low.
Summary of the invention
The object of the present invention is to provide a kind of rope band stress measurement and display device, solve the problem that existing measurement mechanism measurement range is limited, the measurement data precision is low.
For addressing the above problem, the technical solution used in the present invention is:
A kind of rope band stress measurement and display device, comprise the rope band location axle pin that is installed on the pier and the sensor of middle part projection, pier inside is provided with cavity, described rope band location axle pin has two, be separately positioned on the sensor both sides and be parallel to each other with the middle part projection of sensor, sensor is connected with microcontroller by signal conditioning circuit, and microcontroller also is connected with digital indicator.
Further technical scheme is: above-mentioned signal conditioning circuit can be signal amplification circuit, signal denoising circuit or signal excitation circuit.
Further technical scheme is: above-mentioned microcontroller is for can demarcate microcontroller.
Principle of the present invention is: by the rope band location axle pin of both sides, the position relation of the projection of sensor, with the stress transmission of rope band is pressure to sensor, sensor with stressed variation conversion change in physical properties, such as readable electronic signals such as resistance or frequencies, after this changes excitation, denoising and gain by modulate circuit and amplifies, through the conversion input microcontroller of signal conditioning circuit, microcontroller according to before nominal data calculate measurement result and output to digital indicator.After the conversion of excess pressure, can reduce requirement to transducer range, owing to adopted sensor and modulate circuit, the subtle change of rope band stress can both be reflected, so this measurement mechanism can obtain higher measuring accuracy; Owing to adopted digital indicator, so the direct reading of this device is not estimated the very big number of degrees mode of equal error of reading and need not adopt.
Adopt the beneficial effect that technique scheme produced to be: to convert the stress of rope band to electronic signal input microcontroller after the signal conditioning circuit arrangement again by sensor, and on digital indicator, show, not only easy to use, simple to operate, reading is quick, and measurement data is very accurate.

Embodiment
Following the present invention does and describes in further detail:
As Fig. 1: a kind of rope band stress measurement and display device, comprise the rope band location axle pin 2 that is installed on the pier 5 and the sensor 4 of middle part projection, pier 5 inside are provided with cavity 3, described rope band location axle pin 2 has two, be separately positioned on sensor 4 both sides and be parallel to each other with the middle part projection of sensor 4, sensor 4 is connected with microcontroller by signal conditioning circuit, and microcontroller also is connected with digital indicator.
In stress measurement of this rope band and display device, signal conditioning circuit can be signal amplification circuit, signal denoising circuit or signal excitation circuit, and microcontroller is for can demarcate microcontroller.
As shown in Figure 2, adopt above-mentioned a kind of rope band stress measurement and display device to measure rope band stress: rope band 1 is passed space between two rope band location axle pin 2 and the sensor 4, do not contact with pier 5, rope band location axle pin 2, when the relative position relation of sensor 4 need guarantee that rope band 1 is tightened up, can not be pulled to level fully owing to the projection of sensor 4, rope band 1 forms protuberance at sensor 4 high spots, only contact with sensor 4 when rope band 1 is tightened up simultaneously with rope band location axle pin 2, do not contact with pier 5 or other objects, thereby guarantee that measuring process is not subjected to the interference of other external force, cavity 3 plays the effect that guarantees that sensor 4 can free deformation when stressed in the pressure bearing scope.During work: when rope band 1 stressed tension, the relative position relation of rope band location axle pin 2 and sensor 4 is a pressure to sensor 4 with the stress transmission of rope band 1, sensor 4 stress and deformations, thereby change sensor 4 as physical characteristicss such as resistance value or frequency values, feeble signal of bridge circuit output that sensor 4 is formed is to signal conditioning circuit, after handling, signal conditioning circuit is admitted to microcontroller, carry out analog to digital conversion, microcontroller is according to data converted and predefined calibration value, calculate rope band stress, be presented on the digital indicator.
As shown in Figure 3, adopt above-mentioned a kind of rope band stress measurement and display device to measure rope band collar stress: the rope band collar 8 to be looped around on the strainer pivot pin 7 of strainer 6, utilize rope band location axle pin 2 and sensor 4 entire equipment to be fixed on the side of the rope band collar 8, rope band location axle pin 2 only contacts with a side of the rope band collar 8 when straining with sensor 4, whole device not with the rope band collar 8 other sides, do not contact with other objects yet.Its principle of work is identical with the stress of the measurement rope band collar 8 with using method.
