[0026] Embodiment:
[0027] According to Figure 1 A kind of rubber support shear angle quick measuring device of bridge in service shown in the figure, including measuring frame, angle measuring protractor 3 and angle measuring support rod 6;The measuring frame is the movable frame structure of frame edge rotatable, angle measuring protractor 3 is connected on measuring frame;The two ends of the angle measuring support rod 6 are rotatably connected on measuring frame, and one end thereof is located on the center point of angle measuring protractor 3.
[0028] In actual use, the side of measuring frame is contacted with the shear surface to be measured of measured rubber support 12, since the measuring frame is the movable frame structure of frame edge rotatable, the inclination of the side wall of measured rubber support 12 will cause the deflection rotation of measuring frame, drive angle measuring support rod 6 to deflect simultaneously, the angle of deflection is displayed on angle measuring protractor 3, to accurately measure the shear angle of bridge rubber support.
[0029] In some embodiments, the measuring frame includes bottom fixed measuring touch rod 1, top movable measuring touch rod 2, first support rod 4 and second support rod 5;The bottom fixed measuring touch rod 1 and top movable measuring touch rod 2 are arranged in parallel up and down;The first support rod 4 and second support rod 5 are rotatably connected between bottom fixed measuring touch rod 1 and top movable measuring touch rod 2 respectively, and the first support rod 4 and second support rod 5 are parallel;The two ends of the angle measuring support rod 6 are rotatably connected on bottom fixed measuring touch rod 1 and top movable measuring touch rod 2 respectively;The straight edge of angle measuring protractor 3 is connected on bottom fixed measuring touch rod 1.
[0030] Further, the bottom fixed measuring touch rod 1, the top movable measuring touch rod 2, the first supporting rod 4 and the second supporting rod 5 form a rectangle.
[0031] Further, the angle measuring supporting rod 6 is a straight rod, and the central axis is provided with an angle indicating scale line 7.
[0032] In specific application, the angle measuring protractor 3 is fixed in the middle position of the bottom fixed measuring touch rod 1 through an angle measuring protractor fixing screw 9; and the angle measuring supporting rod 6 is hinged with the bottom fixed measuring touch rod 1 and the top movable measuring touch rod 2 through measuring supporting rod hinge bolts 8 respectively.
[0033] In actual use, the same side ends of the bottom fixed measuring touch rod 1 and the top movable measuring touch rod 2 contact the to-be-measured shear surface of the measured rubber support 12, when the measured rubber support 12 is inclined, the top movable measuring touch rod 2 will move forward or backward, and the angle measuring supporting rod 6 will synchronously rotate forward or backward, according to the parallelogram principle, the included angle formed by the rotation of the angle measuring supporting rod 6 is equal to the inclination angle of the to-be-measured surface of the measured rubber support 12, and the inclination angle of the measured rubber support 12 is read out by using the coincidence value of the angle indicating scale line 7 on the angle measuring supporting rod 6 and the scale degree on the angle measuring protractor 3, that is, the shear angle of the measured support.
[0034] The size of the bottom fixed measuring touch rod 1 and the top movable measuring touch rod 2 can be designed according to the distance between the operator and the support surface of the abutment top surface, so as to facilitate the remote measurement of the support by the operator. In specific application, the length of the bottom fixed measuring touch rod 1 and the top movable measuring touch rod 2 can be equal, and the distance between the first supporting rod 4 and the second supporting rod 5 is less than the length of the bottom fixed measuring touch rod 1.
[0035] In some embodiments, a horizontal indicating level bubble 10 is further included, and the horizontal indicating level bubble 10 is horizontally installed on the bottom fixed measuring touch rod 1.
[0036] Further, the horizontal indicating level bubble 10 is arranged on the outer side surface of the bottom fixed measuring touch rod 1.
[0037] In specific application, the arrangement of the horizontal indicating level bubble 10 can level the bottom fixed measuring touch rod 1 by using the horizontal indicating level bubble 10 before testing, so as to keep the bottom fixed measuring touch rod 1 horizontal and ensure the accuracy of the measurement data. The horizontal indicating level bubble 10 is arranged on the outer side surface of the bottom fixed measuring touch rod 1, so as to facilitate the observation of the horizontal degree.
[0038] In some embodiments, the end head of the bottom fixed measuring touch rod 1 and the top movable measuring touch rod 2 on the same side is a tapered structure, so that the contact between the bottom fixed measuring touch rod 1 and the top movable measuring touch rod 2 and the measured rubber support 12 is point contact, avoiding the influence of foreign matters on the surface of the measured rubber support 12 on the test result, so that the structure of the test is more accurate.
[0039] In some embodiments, the straight edge of the goniometric protractor 3 is connected at the center position between the first support rod 4 and the second support rod 5. The design of this technical solution avoids reading errors caused by different viewing angles.
[0040] In some embodiments, when the bottom fixed measuring touch rod 1 is perpendicular to the first support rod 4, the projection of the goniometric support rod 6 on the goniometric protractor 3 coincides with the perpendicular line of the goniometric protractor 3 passing through the center point and being perpendicular to the straight edge. The design of this technical solution makes the measurement result directly read on the goniometric protractor 3 without conversion, which speeds up the reading speed.
[0041] In some embodiments, the center of the goniometric protractor 3 is 0°, and the two sides are 90°. The goniometric protractor 3 using this scheme is more convenient to read.
