Specific embodiment
The technical solution of the utility model is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of accurate bended pipe curvature measurement device described in the utility model, including pedestal
6,6 upper surface of pedestal is equipped with groove 4, is equipped with pipe measuring scale in groove 4, and pipe measuring scale includes pipe measuring scale 1, solid
Determine pipe measuring scale 2 and pipe measuring scale 23,4 one side of groove is equipped with horizontal scale item 5, is equipped in groove 4 and is surveyed with fixed pipe
The horizontal scale ruler zero mark line 7 that gage 2 is correspondingly arranged, what pipe measuring scale 1 can move left and right is arranged on fixed pipe survey
The one side of gage 2, what pipe measuring scale 23 can move left and right is arranged on the opposite side of fixed pipe measuring scale 2.The above is formed
The utility model basic structure.
The utility model uses such structure setting, by being equipped with groove 4 in 6 upper surface of pedestal, is equipped in groove 4
Pipe measuring scale 1, fixed pipe measuring scale 2 and pipe measuring scale 23, by measuring the spacing between adjacent pipe measuring scale
It is poor with 20 bending height of steel pipe, then by the calculation with Pythagorean theorem, can quickly calculate 20 curvature of steel pipe, structure
It is simple and convenient to operate, registration, reading is quick, work efficiency is high.
More specifically, the pipe measuring scale by outer tube 8 and inner tube 9 socket form, 9 top of inner tube be equipped with it is adsorbable in
Rotatable magnet cap 11 on steel pipe 20, inner tube 9 are equipped with inner tube scale 10, and inner tube 9 is moving up and down to be arranged on outer tube 8
Interior, the cooperation of 8 bottom of outer tube is arranged in groove 4.Using such structure setting, steel tube body is adsorbed in by rotating magnet cap 11
On, then reading is carried out in the inner tube 9 for passing through pipe measuring scale, it is poor so as to obtain 20 bending height of steel pipe.
More specifically, the pedestal 6 uses prismatoid structure setting.
A kind of accurate bended pipe curvature measurement device, specific measuring process are as follows：
With reference to Fig. 2, after curved steel pipe 20 is stably placed in frock 21, curvature measurement device is put for step 1
It puts and bend pipe underface, it should be noted that horizontal scale ruler is horizontal with steel pipe longitudinal axis；
Step 2 along axis trimming curvature measurement setting position, makes fixed pipe measuring scale 2 in alignment with curved steel pipe 20
Center pulls out inner tube 9, and the magnet cap 11 on 9 end of inner tube is made to be adsorbed in 20 bottom of steel pipe, reads fixation measuring ruler 2 and corresponds to
Scale, with K2As reading；
Step 3 moves pipe measuring scale 1 with pipe measuring scale 23 to required position, magnet cap 11 is inhaled respectively
20 bottom of steel pipe is invested, one 1 corresponding scale of pipe measuring scale is read, with K1As reading, and read 23 pairs of pipe measuring scale
The scale answered, with K3As reading；
Step 4 reads simultaneously the spacing between pipe measuring scale 1 at this time and fixed pipe measuring scale 2, with L1As
Reading, and the spacing between fixed pipe measuring scale 2 and pipe measuring scale 23 is read, with L2As reading；
Step 5 with reference to Fig. 1 according to Pythagorean theorem, calculates local curvature and overall curvature, theoretical calculation principle is L2+
(R-a)2=R2, thus solve R=L2/ 2a+a/2, the inverse of curvature, that is, R；When calculating local curvature, L=L1, a=K1-K2；Meter
When calculating overall curvature, L=L2, a=K3-K2。
