Technical Field

[0001] The utility model relates to the field of crack repair, in particular to a device for repairing shallow cracks in highway bridges. Background Art

[0002] Over time, bridge materials, subjected to constant loads and environmental changes, may suffer fatigue damage. Furthermore, temperature fluctuations cause the material to expand and contract, and when these temperature differences are drastic, cracks may develop. Furthermore, uneven settlement can lead to uneven stress on the bridge structure, further causing cracks. Promptly repairing cracks not only extends the life of the bridge and reduces maintenance costs, but also ensures smooth traffic flow and protects the safety of pedestrians and vehicles.

[0003] However, in existing repair work, when filling gaps, regardless of the depth of the gap, the material filling is usually uniform and fixed, and it is difficult to adjust according to the depth of the gap, which will result in less filling material in the deep gap and more filling material in the shallow gap, and will lead to poor repair effect.

[0028] The second embodiment is different from the first embodiment in that:

[0029] The storage tank 2 includes a tank body 201, on which a first motor 202 is mounted. The output end of the first motor 202 extends into the interior of the push frame 1 and is connected to a stirring blade 203. When in use, the stirring blade 203 is driven to rotate by the first motor 202, thereby stirring the repair material inside the tank body 201. In a preferred embodiment, the tank body 201 is a cylindrical structure, and the upper end of the tank body 201 is an open structure. A sealing cover is provided at the opening, and the first motor 202 is mounted on the sealing cover. Furthermore, the tank body 201 is tiltedly mounted on the push frame 1, and the liquid outlet end of the tank body 201 is located near its lower end. The repair material inside the tank body 201 can be guided to the interior of the guide head 3 by the feed pump 5, thereby assisting in guiding the repair material.

[0030] The third embodiment is different from the first embodiment in that:

[0031] The pushing frame 1 includes a connecting frame 102, the upper and lower ends of which are connected to a thrust arm 101 and a travel wheel 104, respectively. The connecting frame 102 is provided with a bottom plate 103 for fixing the auxiliary feed pump 5, the guide head 3, the leveling assembly 4 and the baking lamp 6. In the structure of the pushing frame 1, the connecting frame 102 is tilted, and an arc-shaped support frame is provided on the connecting frame 102 for providing auxiliary support for the tank body 201. When the device is in use, the thrust arm 101 can be used to push the device to move, and the travel wheel 104 can be used to assist the support frame to move;

[0032] Furthermore, a battery pack 7 for supplying power to the first motor 202 , the feed pump 5 , the smoothing assembly 4 and the baking lamp 6 is provided on the bottom plate 103 . The battery pack 7 can be used to supply power to electrical devices on the device.

[0033] The smoothing assembly 4 includes a second motor 401, which is fixedly mounted on the base plate 103. The output end of the second motor 401 is connected to the smoothing wheel 402, which is driven by the second motor 401 to rotate, thereby smoothing the repair material through the rotating smoothing wheel 402.

[0034] The fourth embodiment is different from the first embodiment in that:

[0035] The depth probe 301 includes a vertical rod 301a that is slidably matched with the bottom plate 103. A stopper is provided on the outside of the vertical rod 301a. The stopper is located below the bottom plate 103. A thrust spring 301b is provided on the outside of the vertical rod 301a to push the stopper downward. When the depth probe 301 moves with the push frame 1, the elasticity of the thrust spring 301b can push the stopper downward, so that the bottom end of the depth probe 301 extends into the gap and can move up and down according to the depth of the gap to be repaired. Furthermore, the adjustable grouting head 302 includes a magazine 302a, the top of the hopper box 302a is connected to the liquid outlet of the feed pump 5, the top surface of the hopper box 302a is connected with a plug 302c, the high end of the plug 302c is connected to the high end of the vertical rod 301a, and a retaining ring 302b corresponding to the plug 302c is provided inside the hopper box 302a. The plug 302c is conical and extends into the inner hole of the retaining ring 302b and is arranged corresponding to the retaining ring 302b. The bottom surface of the hopper box 302a is penetrated by a discharge hole 302d. When the device moves, the plug 302c can move up and down with the vertical rod 301a. 302c is moved downward, that is, when the vertical rod 301a moves downward, the plug 302c also moves downward to open the inner hole of the baffle ring 302b, and the repair liquid above the baffle ring 302b can flow through the inner hole of the baffle ring 302b to the bottom of the baffle ring 302b and can be discharged downward through the discharge hole 302d. Furthermore, the bottom surface of the magazine 302a is provided with a guide rod 302e to flow downward, and the repair liquid can be guided by the adjustable grouting head 302 to assist the repair material to enter the repair position. When the vertical rod 301a moves upward, the plug 302c is opened. It also moves upward. After the plug 302c moves upward, the distance between the plug 302c and the inner hole of the retaining ring 302b becomes smaller, that is, the amount of repair liquid that can pass through becomes less. Since the depth probe 301 is located at the front end of the adjustable grouting head 302, and the repair liquid will not be immediately discharged from the discharge hole 302d, there is a distance between the depth probe 301 and the adjustable grouting head 302. In a preferred embodiment, the traveling wheel 104 is driven by a motor, which can ensure the uniform movement of the device and the filling of the material at the repair position.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
