Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway bridge operations, in particular to a crack filling and reinforcement device for highway bridges. Background Art
[0002] After the completion of the construction of highway bridges, during the long-term use process, they are exposed to high temperature and heat, severe cold and frost for a long time, and coupled with the erosion of rainwater, they will gradually become aged. Coupled with long-term traffic and large surface loads, when the load exceeds its bearing capacity, cracks will occur. At this time, the cracks are still relatively small. If not repaired in time, they will gradually increase on the basis of the original cracks until the road bridges are severely damaged, and then renovation is required.
[0003] Currently, for the treatment of cracks, the cement grouting technology is usually adopted. Manual cleaning is carried out with a broom, but it will generate a lot of dust and pollute the environment. Then, a pressure pump is used to inject the cement slurry into the voids of the subgrade filler through a pipeline. The slurry occupies the voids of the subgrade filler in ways such as filling, penetration, and compaction. After manual gravity rolling, the original loose soil particles or cracks are cemented into a whole, forming a consolidated body with a new structure, high strength, good waterproof performance, and good chemical stability. Finally, watering operations are carried out. However, the existing tools are relatively complex. Separate tools are required for cleaning, joint filling, and rolling, which is time-consuming and laborious and seriously reduces work efficiency. Summary of the Utility Model
[0004] In order to overcome the defect of low work efficiency in the prior art, the utility model provides a crack filling and reinforcement device for highway bridges.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a crack filling and reinforcement device for highway bridges, including a vehicle and a storage bin. The storage bin is installed on the upper part of the vehicle. Dust removal devices and spraying devices are respectively arranged on the left and right sides of the storage bin. The installation position of the dust removal device is close to the front of the vehicle, and the spraying device is installed at the rear of the vehicle. A cleaning device connected to the dust removal device is arranged at the bottom of the vehicle. The dust removal device and the cleaning device are connected through a turbo fan. A pumping device connected to the storage bin is arranged at the lower part of the vehicle. The output end of the pumping device is connected with a filling gun. A rolling device is arranged on one side of the pumping device close to the rear of the vehicle.
[0006] As a further improvement of the utility model, a stirring device is arranged in the storage bin. The stirring device includes a stirring rod arranged in the storage bin and a servo motor arranged at the outer top of the storage bin and connected to the stirring rod.
[0007] As a further improvement of the utility model, the dust removal device is a bag filter, and a dust collection box is arranged at the lower part of the dust removal device.
[0008] As a further improvement of the present utility model, the rolling device includes a pressure roller. Both ends of the pressure roller are connected with rolling telescopic cylinders through bearing assemblies, and the rolling telescopic cylinders are installed at the bottom of the vehicle.
[0009] As a further improvement of the present utility model, the cleaning device includes a cleaning housing. A cleaning telescopic cylinder is provided at the top of the cleaning housing. The cleaning telescopic cylinder is installed at the bottom of the vehicle. The top of the cleaning housing is connected to a turbo fan through a hose. A cleaning roller is installed inside the cleaning housing, and the cleaning roller is driven by a cleaning motor installed outside the cleaning housing.
[0010] As a further improvement of the present utility model, a dust-proof flexible plate is installed at the lower part of the cleaning housing.
[0011] Compared with the prior art, the present utility model has the following beneficial effects: In this solution, it integrates cleaning, caulking, rolling and spraying. The cleaning device sweeps the dust particles near the crack, and under the action of the turbo fan, enters the dust removal device and settles through the dust removal device, reducing dust pollution. The filling gun is aligned with the crack, and the material in the storage bin is transported to the filling gun through the pumping device for filling operation.
