Abstract

The utility model relates to a bent pipe angle measuring instrument capable of reading the measured bending angle of a bent pipe directly and marking start points of a circular arc of the bent pipe. The main structure of the bent pipe angle measuring instrument is composed of an angle ruler and a ruler, wherein the angle ruler and the ruler are provided with graduations from the center of a pin hole outward, a contact length of 200mm between the graduation parts and a straight portion of the measured bent pipe is ensured, and the other part of the angle ruler is an ordinary angle measuring instrument. The two rulers are connected through a big hinge pine and a small hinge pin and can rotate by 180 degrees around the big hinge pin. Angle reading parts of the two rulers are connected through the small hinge pin, and the small hinge pin moves in a guide groove of the angle ruler. During measurement, a butterfly nut on the small hinge pin is loosened, straight line portions of the two rulers are tightly attached to a straight line portion at the outer side of the circular arc of the measured bent pipe directly, the bending angle of the bent pipe can be read directly from the angle measuring instrument, and points at which the circular arc is tightly attached to the straight line portions of the two rulers are the start points.

Description

The bend pipe angel measuring instrument
Technical field
The utility model relates to a kind of band straight section bend pipe angle measurement unit, especially can directly read the angle of institute's lateral bending pipe and indicate the starting point of bend pipe circular arc.
Background technology
At present, in relevant industries, adopt generally that setting-out detects the physical dimension of bend pipe on platform, or adopt simple combination ruler to measure arc angle, read institute by angulometer and estimate number.Error is larger, and can not and indicate the starting point of bend pipe circular arc.Especially at the construction field (site), in the situation of bend pipe several roads circular arc, want to detect more accurately the physical dimension of bend pipe, more difficult.
Summary of the invention
Inconvenient and can't accurately indicate fast the technological gap of bend pipe circular arc starting point in order to overcome at present production practices the bend pipe measurement of angle.The utility model provides a kind of Novel elbow pipe angle measurement unit, can not only directly read the numerical value of institute's lateral bending tube angulation, and can indicate the initial point position of bend pipe circular arc.
The technical scheme that its technical matters that solves the utility model adopts is:
The geometrical principle of measuring is seen accompanying drawing 1, and the geometrical principle of measurement is tetragonal interior angle and equals 180 °, alpha+beta+180 °=360 °, α=180 °-β, tested angle γ=180 °-β=α.
Primary structure is comprised of bevel protractor and ruler, and bevel protractor and ruler outwards indicate scale by the pin-and-hole center, and scale partly guarantees with tested bend pipe straight section, the 200mm contact length is arranged, and bevel protractor another part is a common angulometer.Two chis connect by large and small bearing pin, can be around 180 ° of rotations of large bearing pin, and two chi angular readings parts connect by small clevis pin with head, and small clevis pin with head moves in the bevel protractor gathering sill.During measurement, unclamp the wing nut on small clevis pin with head, two chi straight line portioies directly are adjacent to tested bend pipe circular arc outside straight section part, can directly read the angle of bend of bend pipe from the angulometer, and it is exactly the starting point position that circular arc and two chi straight line portioies are adjacent to a place.
The beneficial effects of the utility model are, can directly read the angle of bend of institute's lateral bending pipe and indicate the starting point of bend pipe circular arc, and are simple in structure, under the prerequisite of usage platform not, can detect fast and effectively the crudy of many angle of bend bend pipe.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.

1 bevel protractor 2 large bearing pin 4 pad 5 nuts (2) 6 small clevis pin with head 7 pad 8 butterfly nuts of straightedge rule 3 in figure
Embodiment
Fig. 1 is according to quadrilateral interior angle and equal 360 °, i.e. provable institute angle γ=180 of reading °-β=α.
Fig. 2 bevel protractor 1, straightedge rule 2 is assembled together by large bearing pin 3, and straightedge rule 2 can be around large bearing pin 3 Rotate 180s °, and large bearing pin adopts pad to add double nuts structure, and is anti-loose, can guarantee to rotate flexibly, reliable.Angle indicator divides and adopts small clevis pin with head 6 guide frames, and it adds butterfly nut 8 structures with bevel protractor 1, straightedge rule 2 employing pads, has locking effect during reading, prevents during preservation that dip stick from opening damage voluntarily.
Fig. 3 bevel protractor 1, straightedge rule 2 adopts pad to add the double nut syndeton by large bearing pin.After adjusting running clearance, fix with double nut, anti-loose.
Fig. 4 angle indicator divides, and small clevis pin with head 6 adopts pads to add butterfly nut 8 structures with bevel protractor 1, straightedge rule 2, has locking effect during reading, prevents during preservation that dip stick from opening damage voluntarily.
