Technical Field
[0001] The utility model relates to the technical field of bridge crack repair, in particular to a road bridge crack reinforcement device. Background Art
[0002] During the construction of roads and bridges, cracks are prone to occur. Common cracks are divided into structural cracks and non-structural cracks. Structural cracks can be divided into design structural cracks and construction structural cracks. Non-structural cracks are divided into plastic cracks, temperature difference cracks, long-term dry cracks, crazing cracks and other aggressive cracks. After cracks occur, the strength of the damaged parts will be reduced, the load-bearing capacity will be greatly reduced, and it will be more susceptible to erosion by rainwater. If the cracks are not fixed, the cracks will continue to expand, eventually leading to the need for major repairs or even scrapping of roads and bridges, and in severe cases, the bridges will collapse.
[0003] In the prior art, cracked bridges are mostly repaired and reinforced by pouring cement mortar or asphalt. For example, a road bridge crack reinforcement device disclosed in authorization announcement No. CN220767652U can only fill surface cracks when pouring mortar or asphalt, resulting in the inability to quickly fill mortar and asphalt deep in the cracks. As time goes by, the materials settle, resulting in pits on the surface of the cracks that have just been filled, requiring secondary filling, which is time-consuming and labor-intensive. Therefore, a road bridge crack reinforcement device is needed to solve the above problems. Utility Model Content

[0014] 1. The utility model increases the pressure in the storage tank through a booster mechanism, so that the material can be sprayed to the bottom of the crack at a high speed and accurately, reducing the sedimentation space and sedimentation amount of the material in the falling process, improving the filling efficiency and the use efficiency of the material, while reducing the sedimentation and gaps after repair, and enhancing the durability of the repair effect.

DETAILED DESCRIPTION
[0022] See also Figure 1-Figure 4 A road bridge crack reinforcement device comprises a cart 1 and a storage tank 2, wherein the storage tank 2 is fixedly mounted on the upper end of the cart 1, a pressurizing mechanism 3 is arranged on the upper end of the storage tank 2, and a pressing mechanism 4 is arranged on the rear end of the cart 1;
[0023] The pressing mechanism 4 includes a slider 410 and a pressing plate 420. A discharge pipe 421 is arranged at the bottom center of the pressing plate 420. The discharge pipe 421 is connected to the storage tank 2 through a bellows. A sliding rod 101 is arranged at the rear end of the trolley 1. The slider 410 is sleeved on the sliding rod 101 and is slidably connected to the sliding rod 101 through a sliding bearing. The pressing plate 420 is slidably installed at the lower end of the slider 410.
[0024] Furthermore, the boosting mechanism 3 includes a boosting fan 310 and a pressure relief valve 311 , and the boosting fan 310 and the pressure relief valve 311 are fixedly installed on the top of the storage tank 2 .
[0025] The booster fan 310 is used to blow air into the storage tank 2, thereby increasing the pressure in the storage tank 2, causing the material in the tube to be ejected downward from the discharge pipe 421, allowing the caulking material to directly reach the bottom of the crack, thereby reducing the sedimentation space of the caulking material and reducing the amount of material sedimentation. The pressure relief valve 311 is used to keep the storage tank 2 within a stable pressure range to avoid damage to the booster fan 310 or explosion of the storage tank 2.
[0026] Furthermore, the front end of the pressing plate 420 is tilted upward, and a reinforcing rib 422 is provided on the upper end surface of the pressing plate 420 .
[0027] When the pressure plate 420 is adjusted to fit the upper end surface of the bridge crack, the caulking material is quickly filled into the crack. When the material near the nozzle wants to overflow, it is pressed into the depth of the crack by the pressure plate 420, so that the caulking material receives downward pressure and quickly flows to the bottom of the crack, thereby increasing the caulking speed and reducing dead corners in the gap. The crack can be fully filled in just one time, greatly improving the repair efficiency. The reinforcing ribs 422 enhance the structural strength of the pressure plate 420, and the raised pressure plate 420 structure is not easily stopped by small protrusions on the surface of the bridge.
[0028] Furthermore, a guide rod 423 is provided on the top of the pressure plate 420, a guide hole 413 is provided on the slider 410, the pressure plate 420 and the slider 410 are slidingly connected through the guide rod 423 and the guide hole 413, a rotating connection adjustment bolt 424 is provided on the upper end surface of the pressure plate 420, a screw hole 414 is provided on the slider 410, and the adjustment bolt 424 passes through the screw hole 414 and is threadedly connected to the slider 410.
[0029] By turning the adjusting bolt 424 to adjust the height of the pressure plate 420, the pressure plate 420 can be raised when the equipment is not in use, so as to facilitate the rapid movement of the equipment. When the equipment needs to perform caulking operations, the pressure plate 420 is brought into contact with the bridge deck, so that the discharge pipe 421 is raised into the crack to perform caulking and reinforcement operations on the crack.
[0030] Furthermore, a handle 411 is provided at the upper end of the slider 410 .
[0031] The position of the slider 410 can be conveniently adjusted through the handle 411. Since the crack is of irregular shape, when turning at a small angle, the discharge pipe 421 can slide adaptively along the slide rod 101 under the pressure of the side wall of the crack. When the discharge pipe 421 is stuck, the handle 411 can be manually moved to adjust the position of the discharge pipe 421 to avoid equipment interference.
[0032] Furthermore, a switch 412 electrically connected to the booster fan 310 is provided at the lower end of the handle 411 .
[0033] The switch 412 can be used to conveniently control the start and stop of the booster fan 310, thereby conveniently controlling the material discharge speed, and avoiding excessive material discharge when the crack is too small, resulting in overflow and waste.
[0034] Furthermore, the side wall of the storage tank 2 is provided with thermal insulation cotton 201 .
[0035] The heat preservation effect of the storage tank 2 is improved by the heat preservation cotton 201, so as to prevent the asphalt from being cooled and solidified too quickly and unable to be discharged when the asphalt is stored in the storage tank 2.
[0036] When the device is in use, the device is pushed to the position of the crack to be repaired, and the guide device or visual inspection is used to ensure that the discharge pipe 421 is aligned with the center of the crack. According to the width and depth of the crack, the height of the pressure plate 420 is adjusted by adjusting the bolt 424 to ensure that the front end of the pressure plate 420 can be close to the upper edge of the crack, and at the same time, sufficient space is left for the discharge pipe 421 to smoothly enter the crack. The blower is connected to an external mobile power source or generator, and the booster fan 310 is started by the switch 412 at the lower end of the handle 411. At this time, the booster fan 310 starts to work, and the booster fan 310 is started by the switch 412 at the lower end of the handle 411 to blow and pressurize the storage tank 2, and the filling material is sprayed. The pressure plate 420 can effectively guide and compact the material, reduce material overflow and dead corners, ensure that the crack is fully filled at one time, and greatly improve the repair efficiency. After the crack filling is completed, the booster fan 310 is turned off, the pressure plate 420 is raised, and the device is folded.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
