In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with
Embodiment, the present invention will be described in further detail.It should be appreciated that tool described herein
Body embodiment only in order to explain the present invention, is not intended to limit the present invention.
Below in conjunction with the accompanying drawings the structure of the present invention is explained in detail.
As depicted in figs. 1 and 2, the utilization laser monitoring civil engineering of the embodiment of the present invention is indoor
The device of model displacement by generating laser 1, laser pickoff 2, clear glass case 3,
Support 4 and Position Scale composition.
Generating laser 1 and laser pickoff 2 will fix it in the fixing cunning of laser instrument by nut
On block 4-7, clear glass case 3 is arranged between two bracing frames 4, and slide block fixed by laser instrument
4-7 is fixed on round steel pipe 4-6 by slack adjuster 4-3, and fixing steel loop 4-5 is welded on sharp
The end of the fixing slide block 4-7 of light device, the fixing slide block 4-7 of laser instrument is provided with generating laser 1
The laser sliding with laser pickoff 2 fixes chute 4-4, and round steel pipe 4-6 is fixed on support
On the base 4-1 of frame 4, bracing frame 4 is provided with graduation mark 4-2；Position Scale passes through pine
Tight screw 4-3 is fixed on bracing frame 4.
Support frame as described above 1 includes：Base 4-1, its a size of 300mm*200mm；Pillar
Its a size of high 350mm, external diameter 45mm, internal diameter 37mm for round steel pipe 4-6；Laser
Device (transmitting terminal is generating laser, and receiving terminal is laser pickoff) fixing slide block (two),
Paste the long steel bar of 35mm up and down, middle part is 14mm width chute；Tail end and external diameter be 63mm,
Internal diameter be 45mm fixing steel ring welding, fixation slide block by slack adjuster can move up and down to
Specified altitude assignment is simultaneously fixed, and wherein slack adjuster is the interior hexagonal cylindrical head spiral shell of diameter 10mm
Nail.
Position Scale, Position Scale is that the 30*3 equal leg angle of height 350mm is welded into chi
Frame, by steel ruler being fixed on chi frame slack adjuster, wherein screw is 6mm so far
Hexagon socket cap head screw.Position Scale determines receptor by determining first laser point position
Position.
Clear glass case 3, is the clear glass case of 300mm*300mm*300mm, transparent
There is horizontal and vertical graduation mark on glass box 3, monitored model can be carried out with positioning and place, right
Model loads height and is recognized.
Generating laser 1 (two), transmitting laser beam passes through glass box, by both sides spiral shell
Mother will fix it on fixing slide block.
Laser pickoff 2 (two), receives the laser beam through glass box, by both sides
Nut will fix it on fixing slide block.
Switch and signal indicator, control transmitting and its indicative function of laser.
The operation principle of the present invention：
And adjust fixing for two bracing frames slide blocks to keeping parallelism, one end bracing frame is by Laser emission
Device is fixed, and laser pickoff is fixed by the other end.Tested model is put into clear glass case,
Adjustment laser transmitter positions are required according to tested model deformation, open switch and indicator,
Generating laser sends laser beam, and such as receptor fails to receive laser beam, signal indicator
Upper display lamp lights, and loudspeaker send ring；By Position Scale, laser receiver is adjusted to energy
Receive laser beam position, on signal indicator, display lamp does not work, loudspeaker do not ring, now swash
Light ray is located at the limit displacement value of tested model；Keep indicator for displaying stabilization signal, right
Structural model is loaded, during being further applied load, if it is indicated that device lamp lights, concurrently
Go out ring, then tested model displacement exceeds limit value, is such as added to specified load, device does not have
Send signal, then structural model passes through to load.
Circuit board specific works mode：
As shown in figure 3, J1 end provides 12V unidirectional current VCC_12V_IN by power supply adaptor,
And carry out contactor control by switching S1.When S1 closure, circuit is in running order,
Now power supply indicator D0 lights, meanwhile, Laser emission end P2, P3 and receiving terminal P1,
P4 and the acousto-optic indicating circuit due to LM358-NSC operational amplifier composition are in work
State.By operational amplifier LM358-NSC, diode D1 and buzzer LS1
In one group of acousto-optic indicating circuit that SPEAKER is constituted, input VCC_12V end power supply connects
Enter 12V, by resistance R4, R5 partial pressure so that the 2 terminal voltage perseverances of LM358-NSC are
6V, when receiving terminal P1 receives the signal that Laser emission end P2 sends, by the IN1 in P1
End produces the high level of a 12V, now the positive input of operational amplifier LM358-NSC
For 12V high voltage, LM358-NSC is through comparison voltage, discovery V3>V2 (positive input
More than negative sense input), then export a high voltage (12V) at its 1 end (outfan),
Now D1 and SPEAKER both end voltage is 12V, and no current passes through, and circuit does not work,
D1 display lamp does not light, and SPEAKER loudspeaker do not send ring.
Conversely, when P1 can not receive laser signal, its INI end produces a low-voltage,
Now LM358-NSC pass through voltage ratio relatively after, its 1 end export one than relatively low voltage
(<12V), now there is electric potential difference in D1 and SPEAKER two ends, has electric current to pass through, electricity
Road works, and D1 display lamp lights, and SPEAKER loudspeaker send ring.In the same manner, with P3,
P4 as Laser emission end and receiving terminal, by operational amplifier LM358-NSC, diode
In another group of acousto-optic indicating circuit that D2 and buzzer LS2SPEAKER is constituted, its work
Principle is identical.
Using the effect of Laser Measuring gearshift of the present invention, by the gear soil to student's designed, designed
Wall one class formation thing carries out actual loaded objectively to find and to confirm theoretical knowledge.Increased
Life is objective illustrative to Subjective Knowledge.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All any modification, equivalent and improvement made within the spirit and principles in the present invention etc.,
Should be included within the scope of the present invention.
