Abstract
A calibrating device of a steel rope tensometer comprises an extensible part, a force transducer, a display unit, a steel rope connecting part and a steel rope fixing part. The force transducer can convert self-generated variables into digital signals which are output to the display unit. Due to the sensitiveness of the force transducer, the drawing force measured by the force transducer, namely the tension of the steel rope, is accurate. In addition, the variables of the force transducer are output and displayed in the form of digital signals, thereby being stable and substantially having no deviation during transmission and reading process.
Description
Technical field
The utility model relates to the calibrating indicating instrument field, and especially, the utility model relates to the calibrating installation of cable tension table.
Background technology
The cable tension table is the instrument that is used for the tension force under the survey aircraft control system cable wire duty.In the aircraft field, the slat transmission of MD82 or MD90 type aircraft realizes that by cable wire this cable wire is installed between operating control and the aircraft slat, plays the effect of transmission.So whether the tension force of cable wire reaches the quality safety that installation code is related to aircraft.
In existing cable tension testing, operating personnel at first carry out measurement and calibration to the cable tension table, provide the calibration data table of comparisons, this table of comparisons is the mapping table of cable tension table scale and tension value, then the cable wire on the aircraft is carried out tonometry, read the tensiometer pointer scale, and calculate cable tension according to the calibration data table of comparisons.This shows, the calibration result of cable tension table has reflected directly whether the state of tensiometer is good, quality safety for aircraft plays crucial effects equally, therefore according to aviation measurement verification requirement, need carry out periodic calibration to aircraft cable tension table.
The calibration of existing cable tension table can have following two kinds of methods to realize usually:
1) as shown in Figure 1, design a counterweight domain 101, tension force on demand adds counterweight 102 gradually, by lifting device (for example driving a vehicle 103) counterweight 102 is mentioned again.
According to the requirement of tensiometer vertification regulation, on counterweight domain 101, place the counterweight made in Great Britain 102 of demand, utilize lifting device (for example driving a vehicle 103) pulling cable wire 104 then, counterweight 102 and domain 101 are mentioned together, and tested tensiometer 105 is installed according to mode as shown in the figure.Read tensiometer 105 readings afterwards, this moment, correct corresponding tension value should be the total force in counterweight 102 and domain 101.This method precision is the highest, but cost is bigger, and not easy to operate.
2) with the above-mentioned the 1st) the kind method is similar, but directly do not use counterweight to increase the weight of, but institute's extension counterweight is amplified to required tension value by lever.
Its principle of work is an equalising torque, both F1 * L1=F2 * L2
Wherein: F1 is the tension force of cable wire 201
L1 is the vertical range of the tension direction of cable wire 201 to fulcrum 203
F2 is the gravity that counterweight 202 produces
L2 is the vertical range of the gravity direction of counterweight 202 to fulcrum 203
At first tested tensiometer 204 is installed by mode shown in Figure 2, then according to the requirement of tensiometer vertification regulation, obtain needed tension value by quality and the arm of force distance that changes counterweight 202, read the reading of tensiometer 204 afterwards, the tension force of the correspondence that this moment is correct should be:
This method is strict to each Component Design, and the influence of the friction force between parts is difficult to accomplish to meet 1% requirement during value calibration energetically.Journey cable tension table adopts this method to calibrate more in a small amount at present, but for the above wide range cable tension table of 10kN (20001bf), this method error is bigger.
Therefore, lack a kind of calibrating installation that is suitable for calibrating various range cable tension tables in the prior art.

During use, at first cable wire is fixed on the draw direction of described tensile part, afterwards cable tension table to be checked is installed on the described cable wire by cable wire fixed part and cable wire connecting portion.Then, start tensile part, described cable wire is stretched and produces tension force at draw direction.Simultaneously, force cell also is subjected to the stretching of tensile part thereby produces deformation, and the display unit that is connected with force cell can demonstrate its type variable, the suffered tensile force value of force cell that operating personnel obtain according to the shown type variable conversion Calculation of display unit.Because cable wire produces tension force under the stretching action of tensile part, thus this moment tensile part tensile force just equal the tension force of cable wire, so the tensile force value that operating personnel calculate just should be the tension value of cable wire.At this moment, the tension value shown in this tension value and the cable tension table is contrasted, thereby the cable tension table is calibrated.
Preferably, described cable wire fixed part also is connected with the manual fine-tuning device, the described manual fine-tuning device described cable wire fixed part that can stretch on the draw direction of described tensile part.More preferably, described manual fine-tuning device is threaded rotating disk, and the axle of this rotating disk is passed described cable wire fixed part and is connected with described cable wire.Like this, operating personnel can finely tune cable tension according to the manual fine-tuning device.
Especially, described display unit also comprises conversion element, and it can convert the load cell type variable information that is comprised in the described digital signal to corresponding tension value size.Thus, operating personnel can directly read correct tension value to be used for calibration from display unit.
Preferably, the precision of described force cell is 0.3%, and range is 50kN.
Preferably, described tensile part is the cable wire load testing machine.
Because the induction sensitivity of force cell, so the warp tension ratio that its measured tensile force is a cable wire is more accurate, and the type variable of this force cell is more stable by digital signal output and demonstration, can not produce deviation substantially in transmission and process of reading.
In addition, because what use is the such tensile part of the cable wire load testing machine cable wire that stretches for example, so can calibrate for the cable tension table of various ranges.And the friction force that each parts produces in this calibrating installation is less, so even in the calibration process of wide range cable tension table, also can reach the vertification regulation requirement of tensiometer.
