[0026] A crack filling and reinforcement structure for road bridges, comprising:

[0027] The main body includes a mobile frame 1, with a feeding hopper 11 fixedly connected to the surface of the mobile frame 1. A conveying pipe 12 is fixedly connected to the surface of the feeding hopper 11. A motor 13 and a feeding pipe 14 are fixedly connected to the surface of the conveying pipe 12. A filling head 15 is fixedly connected to the surface of the feeding pipe 14. When repairing cracks in roads and bridges, concrete material needs to be fed into the feeding hopper 11. The start of the motor 13 can drive the screw rod set in the conveying pipe 12 to rotate and transport the concrete into the feeding pipe 14. When the worker aligns the filling head 15 with the crack, the concrete will fill its surface. The filling makes the bridge structure intact and achieves the reinforcement effect. The conveying pipe 12, motor 13 and screw rod form a screw conveyor, which is an existing device, and the filling process is also existing. It will not be described in detail here.

[0028] The storage mechanism includes a fixed rod 2, which is fixedly connected to the surface of the movable frame 1. A support plate 21 and a side plate 22 are fixedly connected to the surface of the fixed rod 2. A mounting block 23 is fixedly connected to the surface of the side plate 22. A movable plate 24 is movably connected to the surface of the mounting block 23. A rotating groove 25 is provided on the surface of the mounting block 23. A rotating rod 26 is fixedly connected to the surface of the movable plate 24. A torsion spring 27 is sleeved on the surface of the rotating rod 26. A threaded block 28 is fixedly connected to the surface of the support plate 21. A fastener 29 is abutted to the surface of the movable plate 24. A groove is provided on the surface of the movable plate 24. Two sets of fixed rods 2 are provided and located on both sides of the support plate 21 and the side plate 22. Both ends of the fixed rods 2 are fixed to the surface of the movable frame 1. The fixed rods 2 can achieve the installation effect of the support plate 21 and the side plate 22.

[0029] Furthermore, two sets of support plates 21 and side plates 22 are provided. The two sets of support plates 21 and side plates 22 are installed on both sides of the fixed rod 2. The cross-section of the support plate 21 is "L" shaped. One side of the movable plate 24 is movably connected to the surface of the side plate 22, and the other side of the movable plate 24 is abutted to the surface of the support plate 21. Under the action of the fixed rod 2, support plate 21, side plate 22 and movable plate 24, a storage space can be formed. When not in use, the feeding tube 14 can be wrapped around its surface for storage.

[0030] Furthermore, two sets of mounting blocks 23 and rotating rods 26 are provided. The two sets of mounting blocks 23 and rotating rods 26 are installed on both sides of the movable plate 24. The rotating rods 26 are rotatably connected to the surface of the rotating groove 25. One end of the torsion spring 27 is abutted and connected to the surface of the mounting block 23, and the other end of the torsion spring 27 is abutted and connected to the surface of the movable plate 24. The movable plate 24 can be installed through the mounting blocks 23. The diameter of the rotating groove 25 is the same as the diameter of the rotating rod 26. With the connection of the rotating groove 25 and the rotating rod 26, the movable plate 24 can rotate around the rotating rod 26. The torsion spring 27 can apply a torsional force to the surface of the movable plate 24 and make it always tend to rotate towards the support plate 21. When the movable plate 24 is against the support plate 21 and the fasteners 29 are not installed on its surface, when the feeding pipe 14 is removed from the support plate 21 in sequence, the movable plate 24 can limit the unremoved part to avoid the situation where it falls off completely due to inertia.

[0031] Furthermore, two sets of threaded blocks 28 are provided. One set of threaded blocks 28 is fixedly connected to the surface of the support plate 21, and the other set of threaded blocks 28 is fixedly connected to the surface of the side plate 22. The threaded blocks 28 are engaged with the surface of the groove. The fasteners 29 are threadedly connected to the surface of the threaded blocks 28. With the connection of the fasteners 29 and the two sets of threaded blocks 28, the movable plate 24 can be limited and fixed when it is placed on the support plate 21 and the side plate 22 respectively. The fasteners 29 consist of a nut and a screw ring.

[0032] Furthermore, the surface of the feed hopper 11 is provided with an expansion mechanism, which includes a mounting frame 3. The mounting frame 3 is abutted against the surface of the feed hopper 11. A fixing block 31 is fixedly connected to the surface of the feed hopper 11. The surface of the fixing block 31 is provided with an insertion hole 32 and a threaded groove 34. An insertion rod 33 is fixedly connected to the surface of the mounting frame 3. The surface of the insertion rod 33 is provided with a through hole 35. A bolt 36 is installed on the surface of the fixing block 31. Under the action of the mounting frame 3, the filling material can be guided. The inner side of the mounting frame 3 has a certain slope, and the outer diameter of the mounting frame 3 is larger than the size of the feed inlet of the feed hopper 11.

[0033] Furthermore, there are two sets of fixing blocks 31 and insert rods 33. The two sets of fixing blocks 31 are installed on both sides of the feed hopper 11, and the two sets of insert rods 33 are installed on both sides of the mounting frame 3. The diameter of the insertion hole 32 is the same as the diameter of the insert rod 33. The insert rod 33 is inserted into the surface of the insertion hole 32. With the connection between the insert rod 33 and the fixing block 31, the mounting frame 3 and the feed hopper 11 can be connected. The insert rod 33 passes through the surface of the fixing block 31 through the insertion hole 32.

[0034] Furthermore, the bolt 36 is inserted into the surface of the threaded groove 34, one end of the bolt 36 is threaded into the surface of the through hole 35, and the other end of the bolt 36 is abutted into the surface of the fixing block 31. With the connection of the bolt 36, the threaded groove 34, and the through hole 35, the insertion rod 33 can be limited and fixed on the surface of the insertion hole 32 to achieve the connection effect between the fixing block 31 and the insertion rod 33.

[0035] Working principle: When the operator is not using the feed pipe 14, the movable plate 24 is first rotated towards the side plate 22 with the rotating rod 26 as the center, so that the rotating rod 26 rotates on the surface of the rotating groove 25. The torsion spring 27 is in a torsional state. When the movable plate 24 abuts against the side plate 22, the groove on its surface is engaged with the set of threaded blocks 28. Then, the fastener 29 is aligned with the threaded block 28 and rotated, so that it is connected to the threaded block 28 through the thread and abuts against the surface of the movable plate 24 when tightened. At this time, the feed pipe 14 can be wound around the inner side of the two sets of support plates 21 in sequence. After the feed pipe 14 is completely stored, the fastener 29 is rotated again to remove it. The movable plate 24 rotates again under the torsional force applied by the torsion spring 27 and abuts against the support plate 21. Finally, the fastener 29 is connected to the surface of the threaded block 28 on the support plate 21 to limit the movable plate 24, so that the movable plate 24 will not shake due to vibration when the structure moves.

[0036] Before the staff uses the filling and reinforcement structure, the mounting frame 3 is placed above the feed hopper 11 and the insertion rod 33 is aligned with the insertion hole 32 for insertion. When the mounting frame 3 is against the feed hopper 11, the threaded groove 34 and the through hole 35 are aligned. Then, the bolt 36 is inserted into the threaded groove 34 and rotated, so that the small end of the bolt 36 is connected to the surface of the through hole 35 through the thread, while the large end is against the fixing block 31, thereby realizing the installation of the mounting frame 3.
