Detailed description of the invention
The invention will be further described for embodiment shown in below in conjunction with the accompanying drawings:
Seeing shown in accompanying drawing 1, a kind of have monitoring analysis and the spring support hanging frame of warning function automatically, and it includes for arranging pipe
The connector 1 in road 4 and two suspension parts 2 for connector 1 of slinging, suspension part 2 include spring assembly 21, upper hanger 22 and under
Suspension rod 23, the upper end of upper hanger 22 is fixedly installed on hanger bracket 5, and bottom connects the top of spring assembly 21；Lower suspension rod
The upper end of 23 is fixedly installed with the bottom of spring assembly 21, and bottom is fixedly installed with connector 1, and spring support hanging frame also includes
It is arranged on upper hanger 22 and for detecting the strain transducer 3 of the STRESS VARIATION of upper hanger 22, strain transducer 3 can be accepted
Information making dynamically analyze and the processing system of early warning.
Seeing shown in accompanying drawing 2, two strain transducers 3 are arranged on identical height, and are oppositely disposed at upper hanger 22
Both sides.Further, strain transducer 3 is arranged along the length direction of upper hanger 22.Strain transducer 3 is along with the shape of upper hanger 22
Become and deformation.Strain transducer 3 may be arranged as 1 or multiple in other embodiments.
In the present embodiment, the ultimate principle of strain transducer 3 is to measure the line strain of component surface with resistance strain gage, then
A kind of Analysis of Experimental Stress method of component surface stress state is determined according to strain stress relationship.Strain transducer 3 is fixed
On upper hanger 22 surface, when suspension rod deforms, the resistance-strain sheet resistance values in strain transducer 3 will occur corresponding change,
Then by resistance strain gauge, this resistance variations is converted into the change of voltage, then is converted into strain value or output and this strain
The signal of the voltage being directly proportional, is carried out record by monitor, so that it may obtain measured strain or stress, finally by computer
The load of spring support hanging frame is i.e. can get after software platform conversion.Two strain sensings 3 on every upper hanger 22 use favour stone
Electric bridge mode connects, and participates in shown in accompanying drawing 3, R1 and R3 in figure is two strain sensings 3 on a upper hanger 22, R2 and R4
For compensating plate, the signal gathered with enhancing.
