Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crack reinforcement for road bridges, and more specifically, it relates to a crack reinforcement device for road bridges. Background Art
[0002] In the existing road and bridge maintenance technology, crack reinforcement is a crucial task. The currently widely used crack reinforcement devices usually rely on a mobile trolley system to complete the operation. This method allows maintenance personnel to accurately move the reinforcement equipment to the designated positions on the bridge or road, so as to timely and effectively handle the detected cracks. The advantage of this mobile system lies in its flexibility and adaptability, which can cope with cracks in different positions and types, improving the efficiency and coverage of the maintenance work.
[0003] However, the existing mobile trolley system also exposes some limitations in practical applications. The most significant problem is the inconvenience of angle adjustment. During the crack reinforcement operation, precise angle adjustment is crucial for ensuring the repair quality. Due to the irregularity of the bridge and road surfaces, as well as the complex trend of the cracks themselves, operators often need to make fine angle adjustments to the reinforcement equipment to ensure that the repair materials can accurately and evenly fill the cracks. However, the current trolley design performs poorly in this regard. The adjustment process is often cumbersome and time-consuming, and sometimes it even fails to reach the ideal working angle. This defect not only reduces the operation efficiency but also may affect the quality and durability of the repair, thus weakening the effect of the entire crack reinforcement process.

[0015] (III) Beneficial effects
[0016] Compared with the prior art, the present utility model provides a crack reinforcement device for road bridges, having the following beneficial effects:
[0017] 1. The design of the rotating mechanism solves the problem of inconvenient angle adjustment in the prior art. By providing components such as a storage tank, a connecting pipe, a one-way tube, and a fitting head on the moving vehicle, and making the connecting pipe rotatably connected to the storage tank, flexible angle adjustment is achieved. The operator only needs to drive the one-way tube to rotate through the handle to easily change the position and angle of the fitting head, enabling it to accurately align with the crack. This design greatly improves the adaptability and operation convenience of the device, enabling it to handle various complex crack conditions, thereby significantly enhancing the efficiency and quality of crack reinforcement.
[0018] 2. The design of the sealing mechanism effectively controls the flow and sealing of asphalt. By installing a receiving sleeve and a one-way disc in the one-way tube and connecting the one-way disc to the push rod, a reliable sealing system is formed. When the push rod is not pushed, the one-way disc closely adheres to the receiving sleeve to prevent asphalt leakage. When reinforcement operations are required, pushing the push rod can release the seal and allow asphalt to flow into the fitting head. This design not only ensures precise control of asphalt, avoids unnecessary waste, but also improves the cleanliness and safety of the entire reinforcement process.
[0019] 3. The design of the adjustment mechanism provides fine adjustment capabilities for the entire device. By setting a threaded ring in the one-way tube and cooperating with the threaded section, along with components such as a spring, a bottom sleeve, and a thrust bearing, precise control of the sealing force is achieved. The operator can change the tension of the spring by rotating the threaded section, thereby adjusting the sealing pressure of the one-way disc. Brief Description of the Drawings

[0029] Please refer to Figures 1-5 , a crack reinforcement device for road bridges, comprising a mobile vehicle 1, on which a rotating mechanism is provided. The rotating mechanism includes a storage tank 2, a push rod 3, a connecting pipe 4, a handle 5, a one-way pipe 6, a follower rod 7, a corrugated pipe 8, a fitting head 9, an adjusting mechanism and a sealing mechanism. The storage tank 2 is installed on the mobile vehicle 1, the follower rod 7 is installed on the mobile vehicle 1, one end of the connecting pipe 4 is rotatably connected to the side wall of the storage tank 2, the other end of the connecting pipe 4 is connected to the one-way pipe 6, one end of the corrugated pipe 8 is connected to the one-way pipe 6, and the other end of the corrugated pipe 8 is connected to the fitting head 9. The adjusting mechanism is cooperatively connected to the one-way pipe 6 and the push rod 3, and the sealing mechanism is installed in the one-way pipe 6. A handle 5 is coaxially installed on the push rod 3. The adjusting mechanism includes a threaded section 10 and a threaded ring 11. The threaded ring 11 is coaxially installed on the inner wall of the one-way pipe 6, the threaded section 10 is threadedly connected to the threaded ring 11, and the push rod 3 is slidably connected to the threaded section 10. A follower frame 12 is provided on the inner wall of the fitting head 9, an intermediate rod 13 is provided on the push rod 3, and the intermediate rod 13 abuts against the follower frame 12. A rotating disc 14 is coaxially provided on the upper end surface of the threaded section 10, and a sealing ring 15 is provided on the lower end surface of the threaded section 10. A sealing sleeve is slidably connected in the one-way pipe 6. A spring 16 is provided on the threaded section 10, and a bottom sleeve 17 is provided on the spring 16. The bottom sleeve 17 is slidably connected to the push rod 3. The sealing mechanism includes a receiving sleeve 18 and a one-way disc 19. The receiving sleeve 18 is installed on the inner wall of the one-way pipe 6, the one-way disc 19 is installed on the push rod 3, the one-way disc 19 abuts against the receiving sleeve 18.

The thrust bearing 20 is slidably connected to the push rod 3.
[0030] In this embodiment, when it is necessary to reinforce a crack, first, the mobile vehicle 1 needs to be moved to the corresponding position. Since it is relatively inconvenient to adjust the angle of the mobile vehicle 1, then the handle 5 is used to drive the one-way pipe 6 to rotate. Since the connecting pipe 4 is rotatably connected to the storage tank 2, the fitting head 9 can be driven to move the angle. Then, the push rod 3 is pushed. First, the seal between the one-way disc 19 and the receiving sleeve 18 is released, and the asphalt will flow into the fitting head 9 through the storage tank 2 and the one-way pipe 6, and will be pressed against the follower frame 12 under the action of the middle rod 13. Therefore, the bellows 8 will be stretched and then the fitting head 9 will be fitted to the crack, thus completing the process of angle adjustment. Then, the fitting head 9 is tightly fitted to the crack, so that the asphalt can flow into the crack, thus completing the reinforcement process.
[0031] More specifically, when it is necessary to adjust the sealing force of the one-way disc 19, first, the threaded section 10 is rotated. Since the threaded section 10 and the threaded ring 11 are in threaded connection, and the rotation connection between the spring 16 and the one-way disc 19 is ensured by the thrust bearing 20, then the tension of the spring 16 can be changed, thereby changing the seal of the one-way disc 19, and thus completing the adjustment process.
[0032] In summary, when the overall equipment is in use or operation: when it is necessary to reinforce a crack, first, the mobile vehicle 1 needs to be moved to the corresponding position. Since it is relatively inconvenient to adjust the angle of the mobile vehicle 1, then the handle 5 is used to drive the one-way pipe 6 to rotate. Since the connecting pipe 4 is rotatably connected to the storage tank 2, the fitting head 9 can be driven to move the angle. Then, the push rod 3 is pushed. First, the seal between the one-way disc 19 and the receiving sleeve 18 is released, and the asphalt will flow into the fitting head 9 through the storage tank 2 and the one-way pipe 6, and will be pressed against the follower frame 12 under the action of the middle rod 13. Therefore, the bellows 8 will be stretched and then the fitting head 9 will be fitted to the crack, thus completing the process of angle adjustment. Then, the fitting head 9 is tightly fitted to the crack, so that the asphalt can flow into the crack, thus completing the reinforcement process. When it is necessary to adjust the sealing force of the one-way disc 19, first, the threaded section 10 is rotated. Since the threaded section 10 and the threaded ring 11 are in threaded connection, and the rotation connection between the spring 16 and the one-way disc 19 is ensured by the thrust bearing 20, then the tension of the spring 16 can be changed, thereby changing the seal of the one-way disc 19, and thus completing the adjustment process.
