Abstract
A kind of tension transducer with resistance strain pieces of measuring rope pull, the support at elastic beam center and two ends make the rope generation warpage of tested pulling force.The force action of flex portion rope pull is in elastic beam.Make it produce strain, take place to post resistance strain gage than the position of strong strain at beam.Reach the purpose of measuring rope pull by the measuring resistance foil gauge.
Description
The present invention relates to a kind of resistance strain sensor of measuring rope pull.
Existing pillar tension transducer with resistance strain pieces is to stick resistance strain gage in the column type elastomer side, reach the purpose of measuring pulling force by measuring the elastomeric strain of pillar, this sensor construction is simple, and is highly sensitive, the both available pointer of measurement result, numeral, but also teletransmission remote control.But the elastic body of this kind sensor directly bears measured whole pulling force, for guaranteeing measuring accuracy, elastomeric safety coefficient can not be too high, so this pulling force sensor is applicable to the quiescent load in the scope of can surveying, dynamic load, the dynamic load that particularly surpasses measurement range causes the infringement of sensor easily.
The purpose of this invention is to provide a kind of be suitable for measuring dynamic load, precision height, long tension transducer with resistance strain pieces of life-span.
The present invention constitutes like this: an elastic beam, at its two ends and centre three rope fulcrums are arranged, this three fulcrum is on the plane, rope forms the two equilateral of isosceles triangle between three fulcrums, resistance strain gage is posted at the position that can produce big strain at beam, and the fulcrum of elastic beam one or both ends is the roller fulcrum, so when rope bears pulling force, elastic beam produces deformation in the centre stressed as free beam basically, can measure pulling force on the rope by resistance strain gage.
Elastic beam of the present invention can be processed into cylindrical, rectangle, I-shaped and multiple tubular.By selecting difform elastic beam, conversion elastic beam length and cross dimensions, strengthen or dwindle rope and between three fulcrums, form the equilateral angle of isosceles triangle two, make elastic beam produce the component size of strain with control, and then the grasp dependent variable that elastic beam produced, because the strain that produces in the elastic beam work is microstrain, and is slight to the influence of linear signal, can ignore.
According to design of the present invention, made a tension transducer with resistance strain pieces for test, its structure as shown in Figure 1, the material of elastic beam (1) is the 1Cr18Ni9Ti stainless steel, long 250 millimeters, section is 12 * 16 millimeters in a rectangle (wide * height), the rope fulcrum at elastic beam two ends is pulley (2), pulley spindle takes off easily or loads onto, so that when rope is zero load, easily tension transducer with resistance strain pieces is contained on the rope (4), or take off from rope (4), distance between the pulley fulcrum is 250 millimeters, and intermediate support is fore-set (3), and the rope center line is 12 millimeters in the discrepancy in elevation of two ends fulcrum and intermediate support.Upper and lower faces at elastic beam (1) posts resistance strain gage (5).The tension transducer with resistance strain pieces of this test usefulness is through demarcating, and to 200 kilograms, measuring accuracy is 1% to measurement range from zero.The component that makes elastic beam produce deformation is 19.11% of rope pull.The present invention has designed corresponding rope pulley according to the multiple diameter rope, remains unchanged in the discrepancy in elevation of two ends fulcrum and intermediate support to guarantee the rope center line.By adjusting fore-set (3) height the measurable range of same sensor is changed.
This kind tension transducer with resistance strain pieces is except the various advantages with pillar pulling force sensor, because its rational structure, even bear at rope in the situation of maximum permission dynamic loading, the deformation of spring beam also exceeds the elastic deformation scope far from, thereby unlikely destruction, so its long service life.
Claims (3)
1, a tension transducer with resistance strain pieces of being made up of elastic body, rope supporting mass and resistance strain gage is characterized in that, elastic body is an elastic beam (1), and it is stressed to be free beam with producing the deformation mode.
2, by the tension transducer with resistance strain pieces of claim 1 regulation, it is characterized in that the elastic beam section can be rectangle or I-shaped or tubulose.
3, press the tension transducer with resistance strain pieces of claim 1 or 2 defineds, it is characterized in that by selecting the pulley of corresponding wire rope for use, guarantee that the rope center line is constant in the discrepancy in elevation of two ends fulcrum and intermediate support, adjust fore-set (3) highly, make can the survey scope changing of same sensor.
