Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] Please refer to Figures 1-8 The utility model provides a kind of technical scheme: a bridge crack reinforcing structure, including bridge body 1 and the crack 2 in the middle part of bridge body 1, the upper side of crack 2 is provided with the screed 3 for shielding crack 2, the lower surface of screed 3 is equipped with recess 4, the inside of recess 4 is rotatably connected with the shaft body 9 for connecting, the surface of shaft body 9 is provided with plug-in structure 5, the upper surface of screed 3 is equipped with the first circular groove 301 for guaranteeing the flatness of the upper end surface of screed 3, the inside of first circular groove 301 is provided with the locking bolt 6 for fixed screed 3, the surface of bridge body 1 is equipped with threaded hole 7, threaded hole 7 and locking bolt 6 are adapted, locking bolt 6 is made to rotate by tool, because locking bolt 6 and threaded hole 7 are adapted, therefore locking bolt 6 will produce displacement, the inside of screed 3 is equipped with cavity 8, the number of cavity 8 is equal to the number of recess 4, and cavity 8 is located at the side of recess 4, the inside of cavity 8 is rotatably provided with the connecting ring 11 for connecting and transmission.

[0033] The inner wall of the connecting ring 11 is fixedly connected with a synchronization block 1101, and a synchronization groove 601 is provided on the surface of the locking bolt 6. The synchronization block 1101 is slidably connected to the inside of the synchronization groove 601. By inserting the locking bolt 6 into the inside of the first circular groove 301, the synchronization block 1101 inside the connecting ring 11 will slide into the synchronization groove 601 opened on the surface of the locking bolt 6, and the shaft body 9 rotates and passes through the interior of the cavity 8. One end of the shaft body 9 located inside the cavity 8 is fixedly sleeved with a pull rope 10 that plays a connecting and driving role. The movement of the pull rope 10 will drive the shaft body 9 to rotate, and the rotation of the shaft body 9 can drive the plug-in structure 5 to rotate out of the groove 4. The other end of the pull rope 10 is fixedly connected to the connecting ring 11. Because the cooperation of the synchronization block 1101 and the synchronization groove 601 will drive the connecting ring 11 to rotate synchronously, the pull rope 10 can be wound up by the rotation of the connecting ring 11. The side wall of the crack 2 is provided with a plug groove 12.

[0034] The plug-in slot 12 is larger than the plug-in structure 5 , thereby facilitating the subsequent filling of concrete mortar.

[0035] One end of the shaft 9 located inside the cavity 8 is fixedly connected to a torsion spring 901 for ensuring the stability of the plug-in structure 5 when it is not assembled, and the other end of the torsion spring 901 is fixedly connected to the inner wall of the cavity 8 .

[0036] The plug-in structure 5 includes a connecting plate 501, which is fixedly sleeved on the end surface of the shaft body 9 located inside the groove 4. The internal sliding sleeve of the connecting plate 501 is provided with a plug-in rod 502, and the plug-in rod 502 slides and extends out of the interior of the connecting plate 501. A spring 503 is fixedly connected between the plug-in rod 502 and the inner wall of the connecting plate 501 to facilitate driving the plug-in rod 502 to move. When the plug-in structure 5 rotates, the spring 503 will push the plug-in rod 502 outward and resist the inclined surface of the crack 2 until the plug-in rod 502 rotates to the outside of the plug-in slot 12. The elastic force of the spring 503 will clamp the plug-in rod 502 into the interior of the plug-in slot 12, and finally the leveling plate 3 is fixed.

[0037] The bottom wall of the crack 2 is fixedly connected with a mounting plate 13 which plays a connecting role. The upper surface of the mounting plate 13 is fixedly connected with a fixing rod 14. The surface of the fixing rod 14 is provided with three sliding rings 15 through a card slot sliding sleeve. The surfaces of the three sliding rings 15 are respectively fixedly connected with two first oblique rods 16, two second oblique rods 17 and two third oblique rods 18. The two first oblique rods 16 are fixedly connected to the surface of the lower sliding ring 15, the two second oblique rods 17 are fixedly connected to the surface of the middle sliding ring 15, and the two third oblique rods 18 are fixedly connected to the surface of the upper sliding ring 15. The first oblique rods 16 and the second oblique rods 17 are abutted against each other, and the third oblique rod 18 is abutted against the lower surface of the screed plate 3.

[0038] The upper surface of the leveling plate 3 is provided with a second circular groove 302 for ensuring the flatness of the upper end surface of the leveling plate 3. The upper end of the fixing rod 14 is movably arranged in the second circular groove 302. One end of the fixing rod 14 located in the second circular groove 302 is provided with a threaded groove 19. The upper end of the fixing rod 14 is provided with a threaded sleeve 20. The threaded sleeve 20 is threadedly connected with the threaded groove 19. The threaded sleeve 20 is matched with the second circular groove 302. After the leveling plate 3 is fixed, the upper end of the fixing rod 14 extends into the second circular groove 302, and the threaded groove 19 at the upper end of the fixing rod 14 is exposed. Then, the fixing rod 14 can be fixed again by contacting the threaded sleeve 20.

[0039] The leveling plate 3 is internally provided with an injection through hole 303.

[0040] Working principle:

[0041] When the bridge crack reinforcing structure is in use, the staff uses the equipment to clean and polish the crack 2, and then uses external drilling equipment to form a threaded hole 7 and a plug-in groove 12 on the surface of the bridge body 1. Then, the staff forms a screw hole for fixing the mounting plate 13 on the bottom wall of the crack 2. Then, the mounting plate 13 and the fixing rod 14 are fixed in the crack 2 by bolts. Then, the three sliding rings 15 are respectively sleeved on the outside of the fixing rod 14 through the clamping grooves, and finally the first inclined rod 16 and the second inclined rod 17 are abutted.

[0042] Subsequently, the leveling plate 3 is placed on the upper side of the bridge body 1. At this time, the third inclined rod 18 abuts against the lower surface of the leveling plate 3, and the first circular groove 301 is aligned with the threaded hole 7. Subsequently, the locking bolt 6 is inserted into the inside of the first circular groove 301. At this time, the synchronous block 1101 in the connecting ring 11 slides into the synchronous groove 601 formed on the surface of the locking bolt 6. Then, the locking bolt 6 is rotated by means of a tool. Because the locking bolt 6 is matched with the threaded hole 7, the locking bolt 6 will be displaced. At this time, the synchronous block 1101 will slide in the synchronous groove 601. Because the synchronous block 1101 and the synchronous groove 601 are matched, the connecting ring 11 will be rotated synchronously. At this time, the winding of the pull rope 10 can be realized by the rotation of the connecting ring 11. Because the pull rope 10 is sleeved on the outside of the shaft body 9, the rotation of the shaft body 9 can be realized by the movement of the pull rope 10. The rotation of the shaft body 9 can drive the plug-in structure 5 to rotate out of the recess 4.

[0043] When the plug-in structure 5 rotates, the plug-in rod 502 will be pushed outward by the spring 503 and abut against the inclined surface of the crack 2. When the plug-in rod 502 rotates to the outside of the plug-in groove 12, the plug-in rod 502 will be clamped into the plug-in groove 12 by the elastic force of the spring 503. Finally, the leveling plate 3 is fixed.

[0044] After the screed plate 3 is fixed, the upper end of the fixing rod 14 will extend into the interior of the second circular groove 302, and the thread groove 19 at its upper end will be exposed, and then contact the threaded sleeve 20 to fix the fixing rod 14 for the second time.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
