Description

Multi-purpose engineering check and measuring rule

The utility model belongs to the surveying instrument of linear dimension, plane reference and the gradient, and particularly the method that combines with machinery and electronic technology is the surveying instrument of feature.

At present, use the plumb bob method to carry out mostly to the verticality of bridge pier platform, wall and the measurement of the cubic metre of earth and stone gradient on the engineering.This method measurement is subject to the influence of environment, and measuring accuracy is low, can not satisfy the requirement to the higher level engineering detecting; Another kind method is to use transit survey, but this method required time is longer, and equipment is complicated again, only is applicable to the working-yard use that precision prescribed is high.In addition, Sopwith staff that when cooperating spirit-leveling instrument to carry out the ground or the buildings measurement of higher degree, uses and the ruler of measuring surface evenness, its function all is single.

The purpose of this utility model provide a kind of both can be to the measurement of linear dimension and plane error, the instrument that can measure the gradient again.

The utility model is longitudinally to indicate linear graduation at the ruler back side of being made by hollow profile; Panel board 8 is installed in the front, gradient determination sensor, verticality determination sensor and instrument case 19 are housed in cavity.

Power switch 5, function switch 2, vertical pilot lamp 6 and display 7 are installed on panel board 8.

So-called gradient determination sensor, be perpendicular to the chi face be installed on the axle 22 on the chi wall the circular grating dish 23 that its edge is processed into grating 20 be installed, on a certain circumference of grating dish 23, be processed with four pilot holes 21, the heart angle, garden of per two adjacent pilot holes is 90 degree, and counterweight 11 also is housed on grating dish 23.The spill phototube stent 13 that is installed on the chi wall is arranged on the opposite of grating dish 23, the one side be equipped with can be relative with pilot hole 21 location photoelectric tube 24 and counting photoelectric tube 12,25 that can be relative with grating 20, at opposite side and photoelectric tube opposite position the infraluminescence pipe is installed.

So-called verticality sensor is on the axle 14 that is installed in perpendicular to chi face ground on the chi wall verticality grating pendulum 15 to be installed, and grating pendulum 15 is equipped with grating 28 in its end, and an end of close grating 28 is processed with counterweight 27 and pilot hole 30 successively on the axis of fork.The phototube stent 18 that is installed on the chi wall is arranged on the opposite of grating 28, the one side be equipped with can be relative with pilot hole 30 location photoelectric tube 16 and counting photoelectric tube 17,26 that can be relative with grating 28, be equipped with the infraluminescence pipe at opposite side and photoelectric tube opposite position.Be equipped with damping rubber cushion 29 at the two ends of support 18.

Microcomputer 32, photoelectric counting circuit 31 and photoelectricity positioning circuit 33 are housed in the instrument case 19.

The photoelectric counting circuit is made up of two groups of circuit, and they all are to be made of light emitting diode, photoelectric tube, triode, Schmidt's reshaper and resistance.Circuit in its circuit and " the integrated circuit application example collection of choice specimens " book in " horizontal metroscope automatically " literary composition is identical.

The photoelectricity positioning circuit is to be made of light emitting diode, photoelectric tube, triode, Schmidt's reshaper and resistance.Circuit in its circuit and " the integrated circuit application example collection of choice specimens " book in " horizontal metroscope automatically " literary composition is identical.

In photoelectric counting circuit 31, the light pulse signal that two couples of photoelectric tube D1, BG1 and D2, BG2 detect is nonsynchronous, thereby, after detected two groups of light pulse signals convert electric impulse signal to, amplify by BG4, BG5 respectively, after Schmidt's reshaper F1, F2 shaping, send in the microcomputer 32, both can count, can differentiate direction again.In photoelectricity positioning circuit 33, after the detected light pulse signal of photoelectric tube D3, BG3 converts electric impulse signal to, amplify by BG6, after Schmidt's reshaper F4 shaping, send in the microcomputer 32, give D4 with positioning signal through F3, F5 and R10, BG7 simultaneously, on luminotron D4, positioning signal is shown.The electric impulse signal that microcomputer 32 is sent circuit 31 and 33 here is shown data processed result after sequential operation is handled by display 7.

When measuring the gradient, earlier function switch 2 is got to the slope measuring shelves.Energized switch 5, be placed on ruler on the surface of determinand by erectility again, at this moment gradient grating dish 23 is swung around axle 22 under the effect of counterweight 11, grating 20 is imported computing machine 32 by

photoelectric tube

12,24,25 with count signal and positioning signal, after treating that grating dish 23 stops swinging, microcomputer 32 is presented at data processed result on the display 7, points out the gradient ratio of tested structure.

When measuring vertical is spent, earlier function switch 2 is got to the squareness measurement shelves.The energized switch 5 then, ruler are placed on the surface to be measured by erectility again.At this moment, verticality grating pendulum 15 effect lower swings in counterweight 27.Grating 28 by

photoelectric tube

16,17,26 with count signal and positioning signal input microcomputer 32, treat that verticality grating pendulum 15 stops swinging after, microcomputer 32 is presented at data processed result on the display 7, points out the verticality of tested structure.

This chi also can be used as highroad pavement planeness and measures employed ruler.

This chi cooperates spirit-leveling instrument to can be used as the Sopwith staff of the high precision measurement of higher degree.During use, this ruler is holded up, after the vertical pilot lamp on the chi face 6 is bright, just can be carried out the spirit-leveling instrument reading.

This detection ruler is easy to use, and a chi is used more.

Embodiment:

This detection ruler is that the section bar of rectangle is made by xsect.For easy to carry, it is formed by three sections, every section one meter long.Middle one section is called main scale 3, and two sections of two ends are identical, are called secondary chi 9.Stud with connection

inner sleeve

1 and 4 at the two ends of main scale 3, by them two secondary chis 9 being coupled together becomes three meters long rulers.Longitudinally indicate the scale that precision is 1mm at the back side of ruler, be equipped with panel board 8 in the front of main scale 3.The axle 14 of Slope Transducer, instrument case and verticality sensor all is installed in being connected on the inner sleeve 1 of main scale 3 one ends, and phototube stent 18 is installed on the connection inner sleeve 4 of main scale 3 other ends, is convenient to assembling like this.

So-called

axle

22 and 14 can be made top shape, freely swings to guarantee gradient grating dish 23 and verticality grating pendulum 15.

Counterweight 11 is installed in the end on the line of two pilot holes 21.
