Description
Technical field
The invention discloses a kind of model test strain brick sensor machine table and its operating methods, especially suitable for processing
Brick sensor is strained used in geomechanical model test, and the producing efficiency and precision of strain brick sensor can be improved.
Background technique
In recent years, geomechanical model testing technology constantly improve, and according to the theory of similarity, selects appropriate model material, passes through
Monitoring sensor is buried inside model country rock, by test equipment observation model country rock strain data changing rule, Jin Erfen
The Mechanism of Deformation And Failure of country rock is analysed, this research method has the advantages that intuitive, easy.More and more underground engineerings are adopted at present
It is studied with the method for geomechanical model test, obtains good research effect.
The acquisition of model test strain data relies primarily on the varinodr of answering being embedded in rig for model test, and strain transducer is big
Mostly built-in type, the embedded progress synchronous with modelling of strain transducer.It, need to be using same with country rock to guarantee model test effect
Kind analog material production strain brick sensor, therefore the producing efficiency of strain brick sensor and precision determine the work of model test
Phase and accuracy are most important to experiment success or failure.
Currently, three steps of strain brick sensor production point or less carry out：（1）According to test needs, by particular manufacturing craft, production
Strain brick simultaneously air-dries, and strains test cube of the brick having a size of 2 ~ 5cm of side length；（2）Experimenter is being air-dried using manual operations
Strain brick surface paste three-dimensional strain rosette and connecting terminal, and using electric iron by strain rosette lead and winding displacement in connecting terminal
On welded；（3）Via resistance is welded using multimeter detection, in the reasonable scope, strain brick senses all via resistances
Device is successful.
Since strain brick intensity is lower, in pasting strain rosette and connecting terminal and welding process, shifting need to be rotated repeatedly
Dynamic strain brick easily causes strain brick broken.Strain rosette lead is 0.05 ~ 0.08mm of diameter plain conductor, is easily fractureed；Wiring
Terminal side length only has 8mm, and weld strain flower lead and winding displacement are extremely difficult on strain brick.In the welding process, it not only to protect
It demonstrate,proves lead and conducting wire overlap joint is close, be accurately placed on connecting terminal, also need using solder stick and electric iron, it is necessary to which two people are tight
Close fit could be completed.Therefore strain brick sensor production difficulty is larger.
Common uniaxial train brick sensor only need to paste 1 piece of strain rosette on strain brick surface, weld 6 leads, Mou Xiefu
Miscellaneous test needs to make three dimensional strain brick sensor, i.e., pastes 3 pieces of strain rosettes on 1 piece of strain brick, weld 18 leads, need to disappear
Consume plenty of time and energy.If there is a lead welding failure, this strain brick failure needs accent to make.Geomechanics model
Test strain brick sensor production, be flooded with vast experimental study personnel octanoic acid with it is helpless.Conventional fabrication method, welding process
Middle to need artificial fixed clamp winding displacement, the electric Lip river iron soldering tip of finger distance is closer, and central temperature is up to 800 DEG C, and tin silk is easy after melting
It splashes, scalds test operator.Therefore to accelerate model test progress, improve measuring accuracy, it is necessary to assure strain brick sensing
The producing efficiency and yields of device serve the production of strain brick sensor currently without a set of dedicated tool or equipment, sternly
The development of model test is affected again.
Before making the present invention, application No. is 2016203081306 patents, disclose a kind of for rapid welding foil gauge
Equipment, which is characterized in that equipment body is rectangular parallelepiped structure, and surface carves that there are four arc-shaped wire grooves；The both ends of groove
Opening, one end is connected to the strain frog of cube structure, be put into strain brick, cover conducting wire cover board after can be welded.This
The each strain frog of patent connects two wire grooves, and only cocoa welds 2 leads on strain brick, and uniaxial train brick passes
The strain rosette that sensor is pasted has 6 leads, and two lead angles are 45 degree, this patent is not suitable for strain rosette sensor；
And this patent strain frog size is fixed, and is suitable only for a kind of strain brick welding, is changed if straining brick size, can not just put
Enter groove to be welded.
Before making the present invention, application No. is 2016111617593 patents, disclose one kind convenient for weld strain piece and lead
The easy device and application method of line, which is characterized in that it is made of fixed device, spring pressuring plate, slip pallet and pedestal,
Purpose is to improve the welding efficiency of foil gauge and conducting wire, is not suitable for straining the production of brick sensor.
In consideration of it, needing to invent a kind of tool equipment and its use be capable of quick Fabrication model test and strain brick sensor
Method, to improve model test progress and working efficiency.
