[0027] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and therefore only serve as examples, and cannot limit the protection scope of the utility model.

[0028] Please refer to Figures 1 to 3 The utility model provides a road bridge road slope detection device, including base 10, angle measuring mechanism 20 and fixing mechanism 30, the base 10 is placed on the ground, the inclination angle of slope is measured through angle measuring mechanism 20, and fixing mechanism 30 is fixed after angle and is convenient for reading and recording.

[0029] Specifically, the base 10 is provided with a support frame 11, the angle measuring mechanism 20 includes a dial 21, a rotating shaft 22 and a counterweight ball 23, the dial 21 is fixedly arranged on the support frame 11, the rotating shaft 22 is rotatably arranged at the center of the dial 21, the counterweight ball 23 is connected with one end of the rotating shaft 22 through a hanging rope 231, the dial 21 is provided with a scale line, and the rotating shaft 22 is provided with a pointer 221. The fixing mechanism 30 includes clamping rods 31, the two clamping rods 31 are movably arranged on the dial 21 and symmetrically arranged on the other sides of the other end of the rotating shaft 22, and can clamp the rotating shaft 22.

[0030] After placing the base 10 on the road surface, if the road surface is inclined and has a slope, the counterweight ball 23 drives the rotating shaft 22 to rotate through the hanging rope 231, because the counterweight ball 23 has a large weight, therefore the hanging rope 231 is in the direction of plumb after being stationary. Then the two clamping rods 31 are moved towards each other to clamp the rotating shaft 22, ensure that it remains stationary and fixes the current angle, the angle data can be obtained through the pointer 221 and the corresponding scale line on the dial 21, so that the inclination angle of the road can be obtained.

[0031] Specifically, both ends of the base 10 are provided with support legs 12. Both ends of the base 10 are provided with bar-shaped holes 13 with T-shaped cross sections, the support legs 12 pass through and are slidably connected in the bar-shaped holes 13, and are matched with the shape of the bar-shaped holes 13. The bottom end of the support leg 12 is also provided with a plurality of extension plates 121 around the circumference, and the extension plates 121 are hinged to the support leg 12 through butterfly hinges.

[0032] The device is placed on the ground by the supporting legs 12, which can be more convenient to select a flat place to place, avoiding the uneven ground causing the base 10 to be placed unevenly, and the supporting legs 12 can move in the strip-shaped hole 13 to better select the placement point, and the strip-shaped hole 13 with a T-shaped cross section can limit and support the supporting legs 12. In this embodiment, the top of the supporting leg 12 protrudes out of the strip-shaped hole 13 and is a circular rod with external threads, and is sleeved with a locking nut. After the locking nut is pressed against the surface of the base, the position of the supporting leg can be fixed. In addition, if there is a pit on the ground, the extension plate 121 can be rotated relative to the bottom of the supporting leg 12. After rotation, the bottom of the extension plate 121 is on the same plane as the bottom of the supporting leg 12, thereby increasing the placement area and improving stability.

[0033] Specifically, the fixing mechanism 30 further comprises a gear 32 and a rack 33. The gear 32 is rotatably arranged on the dial 21, and the dial 21 is further provided with a sliding groove. Two racks 33 are movably arranged in the sliding groove and are respectively engaged with both sides of the gear 32 and are respectively connected with two clamping rods 31. The gear 32 is provided with a knob and has a large friction with the dial 21. By rotating the gear 32, the two racks 33 can be moved relatively, thereby moving the two clamping rods 31 respectively, clamping the rotating shaft 22 and fixing the angle.

[0034] Specifically, the outer side of the dial 21 is detachably connected with a concentric angle amplification disc 24. In this embodiment, it is a plug-in detachable connection structure. Since the inclination angle of the road is limited, the dial 21 and the angle amplification disc 24 are both sector discs and are both provided with scale lines in this embodiment. The angle amplification disc has more scale lines. After the rotating shaft 22 is fixed by the clamping rod 31, the angle amplification disc 24 can be installed on the outer side of the dial 21. The pointer 221 is provided with a light emitter. After the light is emitted on the scale line of the angle amplification disc, more accurate angle data can be observed.

[0035] The working principle of the above-mentioned road bridge road slope detection device is as follows: the base 10 is placed on the road surface, and the placement position is adjusted by the supporting leg 12. If the road surface is inclined with a slope, the counterweight ball 23 drives the rotating shaft 22 to rotate through the hanging rope 231, and the hanging rope 231 is in the direction of the plumb line after being stationary. Rotating the gear 32 drives the rack 33 to move, so that the two clamping rods 31 clamp the rotating shaft 22 to be fixed. The angle inclination data of the road can be obtained by the pointer 221 and the corresponding scale line on the dial 21, and more accurate data can be obtained by installing the angle amplification disc 24.

[0036] The above-mentioned road bridge road slope detection device can quickly and conveniently measure the road slope and has high measurement accuracy, which is more practical and convenient.
