Description
Technical field
The utility model relates to a kind of rope band and stress measurement of the rope band collar and display device, relates 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.
The utility model content
The purpose of this utility model is to provide a kind of rope band and stress measurement of the rope band collar and display device, solves the problem that existing measurement mechanism measurement range is limited, the measurement data precision is low.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of rope band and stress measurement of the rope band collar and display device, comprise pressure-sensitive conductive rubber, this pressure-sensitive conductive rubber is fixed on the strainer by the strainer pivot pin, and this pressure-sensitive conductive rubber is connected with microcontroller by signal conditioning circuit, and microcontroller also is connected with digital indicator.
Further technical scheme is: described pressure-sensitive conductive rubber is a ring-type.
Further technical scheme is: described pressure-sensitive conductive rubber is a semicircular.
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.
The pressure-sensitive conductive rubber ring is installed on the strainer pivot pin, and the rope band and the rope band collar are around strainer pivot pin and pressure-sensitive conductive rubber.When rope band and the tension of the rope band collar, rope band and rope band collar stress transmission are the pressure of pressure-sensitive conductive rubber, and then influence the resistance of pressure-sensitive conductive rubber, when being tightened up, rope band and the rope band collar push pressure-sensitive conductive rubber to the inside, the stress of the rope band and the rope band collar is converted into the pressure to pressure-sensitive conductive rubber, pressure-sensitive conductive rubber with stressed conversion change in physical properties, such as readable electronic signals such as resistance or frequencies, this changes the excitation by modulate circuit, after denoising and gain are amplified, through the conversion input microcontroller of signal conditioning circuit, nominal data is calculated measurement result and is outputed to digital indicator before the microcontroller basis.Owing to adopted pressure-sensitive conductive rubber and modulate circuit, the subtle change of rope band and rope band collar 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 change the stress of the rope band and the rope band collar into electronic signal input microcontroller after the signal conditioning circuit arrangement again by pressure-sensitive conductive rubber, and on digital indicator, show, not only easy to use, simple to operate, reading is quick, and measurement data is very accurate.
