Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

See Fig. 1, container F-TR locks depart from intelligent checking system, include four be connected on lifting spreader 06 Individual pulling force sensor 01, the signal identification processor 02 being connected with pulling force sensor 01.

See Fig. 2, four pulling force sensors 01 pass sequentially through signal amplification processor 03, signal output module 04 to be known with signal Other processor 02 is connected, and signal identification processor 02 is connected with the controller of alarm 05 or/and lifting spreader 06.

Pulling force sensor selects pillar strain transducer, and the resistance for including load pillar beam 11 and two double foil gauges should Become piece 12, see Fig. 3, the middle part of load pillar beam 11 is provided with two corresponding blind holes 13, and two blind holes 13 are coaxial and along load The radial symmetric of lotus pillar beam 11, two load pillar beams of the place part of blind hole 13 are structural I-beam, two resistance-strains Piece 12 is adhered to two middle parts of blind hole 13 respectively.

See Fig. 4, two foil gauges in the resistance strain gage of double foil gauges form semi-bridge type strain chip architecture, see Fig. 5, two The resistance strain gage connection composition work electric bridge of the individual pair of foil gauge, pulling force sensor 01 operationally, in resistance strain gage one Individual foil gauge R₁By positive shearing force, that R₂Also by negative shearing force, and the R in another foil gauge₃By positive shearing force, R₄Cut by negative Shear force, when a voltage is added at 1,3 ends, then has a voltage output for positive specific force at 2,4 liang.

1., pulling force sensor can be simplified to two ends stress and concentrate stretching or load pillar beam, and Fig. 6 is shown in mechanical model signal.

2., the pillar stress beam of middle stress load effect is calculated：

Wherein, S represents quiet away from P represents stretching force, A form nominal areas.

3., the shear stress of beam and shearing strain is calculated：

Shear beam sensor generally at the flex point E of strain beam plus two blind holes, be partially formed I-beam, its cut should Power can be calculated with Nikolay Zhuravsky formula：

Wherein, τ represents section shear stress, and b represents the distance between two blind holes；

Strain zone position and stress distribution such as Fig. 7 of structural I-beam such as show.
