DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figure 1-4 A deflection measuring device for bridge monitoring comprises a support 1, a plurality of legs 2 distributed in a circular array are arranged at the bottom of the support 1 to support the support 1, a mounting seat 3 is fixedly connected to the top of the support 1, a plug slot 4 is opened at the top of the mounting seat 3, a plug connector 5 is movably inserted in the plug slot 4, the plug connector 5 is adapted to the plug slot 4, a connecting plate 6 is fixedly connected to the top of the plug connector 5, and a deflectometer body 7 is connected to the top of the connecting plate 6 for measuring the deflection of the bridge. A plurality of mounting grooves 8 are horizontally provided on the inner wall of the plug-in groove 4 and are distributed at circumferential intervals. A bidirectional threaded rod 9 is rotatably connected inside the mounting groove 8. The bottom end of the bidirectional threaded rod 9 passes through the mounting seat 3. Two upper moving blocks 10 and lower moving blocks 11 distributed up and down are threadedly connected to the bidirectional threaded rod 9. When the bidirectional threaded rod 9 rotates clockwise, the upper moving block 10 and the lower moving block 11 will move relative to each other. When the bidirectional threaded rod 9 rotates counterclockwise, the upper moving block 10 and the lower moving block 11 will move in the opposite direction. Except for the side facing the moving plate 12, the other three sides of the upper moving block 10 and the lower moving block 11 are fitted with the mounting groove 8, so that the upper moving block 10 and the lower moving block 11 are more stable when moving. A movable plate 12 is arranged in the installation groove 8, and the movable plate 12 is located between the bidirectional threaded rod 9 and the plug-in groove 4. A first support plate 13 is hinged between the upper movable block 10 and the movable plate 12, and a second support plate 14 is hinged between the lower movable block 11 and the movable plate 12. A plug post 15 is fixedly connected to the side of the movable plate 12 close to the plug-in groove 4. Two plug posts 15 are arranged, which can make the fixation of the plug connector 5 more secure. A socket 16 compatible with the plug post 15 is opened on the outer wall of the plug connector 5. A driving component 17 linked to the bidirectional threaded rod 9 is arranged at the bottom of the mounting seat 3, and the bidirectional threaded rod 9 is driven to rotate by the driving component 17.

[0023] Furthermore, the bottom end of each support leg 2 is provided with an anti-slip sleeve 18 to increase the friction between the bottom end of the support leg 2 and the ground, thereby improving the stability of the device when measuring deflection.

[0024] Furthermore, the limit slide blocks 19 are fixedly connected on both sides of the movable plate 12, and limit slide grooves 20 adapted to the limit slide blocks 19 are opened on both sides of the inner wall of the mounting groove 8. The limit slide blocks 19 are slidably set in the limit slide grooves 20. Through the cooperation between the limit slide blocks 19 and the limit slide grooves 20, the movable plate 12 is more stable when moving in the mounting groove 8.

[0025] Furthermore, a plurality of positioning slots 21 distributed in a circular array are provided on the top of the mounting seat 3 in the vertical direction, and a plurality of positioning blocks 22 corresponding to the positioning slots 21 are fixedly connected to the outer wall of the plug connector 5. The positioning slots 21 cooperate with the positioning blocks 22 to limit the position of the plug connector 5 in the plug slot 4, so that the plug post 15 is aligned with the corresponding plug hole 16, which is convenient for subsequent plugging.

[0026] Furthermore, the driving assembly 17 includes a gear 1701 which is arranged at the bottom of the mounting seat 3 and fixedly connected to the bottom end of each bidirectional threaded rod 9, a shaft ring 1702 is fixedly connected to the outer ring of the mounting seat 3, a sleeve ring 1703 is rotatably connected to the outer ring of the shaft ring 1702, the sleeve ring 1703 rotates around the shaft ring 1702, and an inner gear ring 1704 which is meshed with each gear 1701 is fixedly connected to the inner ring at the bottom of the sleeve ring 1703. The inner gear ring 1704 is driven to rotate by rotating the sleeve ring 1703. When the inner gear ring 1704 rotates, it will drive several gears 1701 to rotate synchronously, thereby driving the bidirectional threaded rod 9 to rotate synchronously.

[0027] Furthermore, the outer ring of the collar 1703 is provided with anti-slip grooves 23, which can increase the friction between the hand and the outer surface of the collar 1703, making it easier to rotate the collar 1703.

[0028] When in use, lift the deflectometer body 7, insert the plug connector 5 under the deflectometer body 7 into the plug slot 4 through the cooperation of the positioning slot 21 and the positioning plug block 22, and then drive the inner ring 1704 to rotate by rotating the ring 1703. When the inner ring 1704 rotates, it will drive several gears 1701 to rotate synchronously, and then drive the bidirectional threaded rod 9 to rotate. At this time, the upper moving block 10 and the lower moving block 11 will move in opposite directions at the same time, and then the moving plate 12 will be pushed to move toward the plug connector 5 through the cooperation of the first support plate 13 and the second support plate 14. At this time, the column 15 will be inserted into the socket 16 to fix the plug connector 5. After the assembly is completed, the device is placed in a suitable position to measure the deflection of the bridge.
