Background technology

Such as Fig. 1, the orientation and elevation that traditional measurement checks and accepts draft tube elbow are the groove point for measuring ell inwall, i.e. a or b points Coordinate, and it is theoretical coordinate c points to design the coordinate for providing, and either measures the three-dimensional coordinate of a points or b points, is finally required for The position of c points is scaled to, the three-dimensional coordinate of the c points that could be so provided with design is compared, so as to judge the orientation of the section ell Whether meet design requirement with elevation, the reserved groove size of cutting is differed when being made due to every section ell, actual at the scene During measurement, often section is required for calculating a or b points to the horizontal and vertical distance of c points that this work amount of calculation is big, and measurement Precision is low.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of measurement of ell and checks and accepts device, the use of the device, Overcome and surveyed when ell is checked and accepted the problem that data are difficult to correct to design load, improve field observation, the efficiency of calculating and elbow Pipe installs the precision checked and accepted.

In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：A kind of ell measurement is checked and accepted Device, it includes small prism, and the small prism is arranged on prism bar, measurement tip and the stainless steel angle of the prism bar Right-angled apices are engaged, and the right-angled apices center of the stainless steel angle is machined with aperture, and the measurement tip is positioned at aperture On, a right-angle side and first groove face of ell body of the stainless steel angle fit, another right-angle side and ell body The second groove face fit, between first groove face and the second groove face by the transition of ell groove be connected；It is described not Rust steel angle bar is fixed on the first groove face of ell body by strong magnets.

The center line and ell centre line marks of the stainless steel angle coincide.

High rigidity steel plate of the stainless steel angle using thickness no more than 1mm is bent into 90 degree.

Small prism bubble is provided with the small prism.

The utility model has the advantages that：

1st, the utility model effectively reduces or evades number of times and the time of every section ell scene amount ac or bc distances, reduces The workload of design point position is corrected, precision and efficiency that ell measurement is checked and accepted is improved.

2nd, the positioning of prism bar can be facilitated by the machining small in stainless steel angle.

3rd, implementation of the present utility model, groove size is measured when solving examination ell repeatedly, is difficult to sit actual measurement Scale value corrects naturalization to the problem of design coordinate value, greatly improves precision and efficiency that ell measurement is checked and accepted.

In figure：Prism bar 1, small prism bubble 2, small prism 3, measurement tip 4, stainless steel angle 5, ell groove 6, ell Body 7, strong magnets 8, ell centre line marks 9, the first groove face 10, the second groove face 11, center line 12, aperture 13.

Specific embodiment

Implementation method of the present utility model is described further below in conjunction with the accompanying drawings.

Referring to Fig. 2-4, device is checked and accepted in a kind of ell measurement, and it includes small prism 3, and the small prism 3 is arranged on prism bar 1 On, the measurement tip 4 of the prism bar 1 is engaged with the right-angled apices of stainless steel angle 5, the right angle of the stainless steel angle 5 Summit center is machined with aperture 13, and the measurement tip 4 is positioned on aperture 13, a right-angle side of the stainless steel angle 5 The first groove face 10 with ell body 7 fits, and another right-angle side fits with the second groove face 11 of ell body 7, described It is connected by the transition of ell groove 6 between first groove face 10 and the second groove face 11；The stainless steel angle 5 passes through strong magnetic Iron 8 is fixed on the first groove face 10 of ell body 7.

Further, the center line 12 and ell centre line marks 9 of the stainless steel angle 5 coincide.By center line Coincidence can improve certainty of measurement.

Further, high rigidity steel plate of the stainless steel angle 5 using thickness no more than 1mm is bent into 90 degree.Pass through It is bent into 90 degree and ensure that it fits with first groove face 10 and the second groove face 11 of ell groove 6, and then simplifies survey Amount process.

Further, it is provided with small prism bubble 2 on the small prism 3.Small prism can interpolate that by small prism bubble 2 3 whether level.

Specific implementation step is as follows：Take block length a 8cm, 2cm wide, high rigidity steel plate of the thickness no more than 1mm, with reference to right angle Guiding ruler rolls at an angle of 90 the steel plate, and two right-angle sides are approximately equal, and are made stainless steel angle 5, in the summit center drill diameter at right angle Small prism is laid when the aperture 13 and then convenient use of about 1mm, accurate measuring finds out the center line on the outside of the right-angle side of steel plate two It is clear with red paint fine rule mark after finishing treatment；When ell measurement is checked and accepted, angle bar is placed on the slope for needing to check and accept point position At mouthful, the center line that will be identified on angle bar is alignd with the center line identified on ell, then strong magnets are placed on angle bar, is made Angle bar is adsorbed on ell, and small prism is stood up in the right-angled apices of angle bar, and the coordinate of the small prism bubble measurable point placed in the middle is obtained The D coordinates value for going out directly is compared with design three-dimensional coordinate, you can judge whether the point meets design requirement.

The above embodiments are only optimal technical scheme of the present utility model, and are not construed as limit of the present utility model System, the technical scheme that protection domain of the present utility model should be recorded with claim, including the technical scheme that claim is recorded The equivalents of middle technical characteristic are protection domain.Equivalent i.e. within this range is improved, also in the utility model Protection domain within.
