AI Technical Summary
Existing highway crack cleaning devices cannot adapt to cracks of different widths, resulting in poor cleaning effects, which affect the quality of crack sealing and the service life of highways.
An adjustable brush spacing highway crack treatment device was designed. The brush spacing is adjusted by sliding a mounting plate on the mounting shaft. Power is provided by a drive motor and a reducer, so that the brushes can flexibly adapt to the crack width.
This allows the brush to fully penetrate the crack, thoroughly removing debris and dust, thus improving the quality of crack sealing and the stability of the road.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of crack cleaning technology, specifically a rapid crack treatment device for highway engineering. Background Technology
[0002] In highway maintenance, crack treatment is a crucial task, as its effectiveness directly impacts the highway's lifespan and driving safety. Currently, the common procedure for treating highway cracks is to first clean the cracks and then fill them with sealant.
[0003] Existing highway crack cleaning devices typically use rolling brushes to clean cracks. This method can remove debris from the cracks to a certain extent, providing favorable conditions for subsequent crack sealing operations and thus improving the stability of the highway after sealing. In terms of drive mechanism, a motor or diesel engine is commonly used to rotate the brush to clean the cracks.
[0004] However, existing roller brushes have significant limitations. Their width is fixed, making it impossible to fully penetrate road cracks of varying widths. This results in poor cleaning effectiveness, failing to completely remove debris from the cracks, and consequently affecting the quality of subsequent crack sealing and the overall success of road crack treatment. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a rapid treatment device for highway cracks in highway engineering, which can adapt to cracks of different widths and achieve better cleaning results.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a rapid treatment device for highway cracks in highway engineering, comprising a mounting frame, an mounting shaft installed inside the mounting frame, mounting plates slidably mounted on the mounting shaft, a brush provided on the outer peripheral wall of each mounting plate, the position of the mounting plate being adjusted along the axial direction of the mounting shaft to adjust the spacing between the brushes on both sides, a sleeve fixedly mounted on the mounting plate, the sleeve being sleeved on the outside of the mounting shaft, a set screw being threadedly connected to the sleeve wall, the rotating end of the set screw being able to abut against the outer wall of the mounting shaft.
[0009] Furthermore, the bottom of the mounting bracket is provided with rollers.
[0010] Furthermore, it also includes a drive motor that provides power for the rotation of the mounting shaft. The drive motor and the mounting shaft transmit power through a reducer. The input end of the reducer is connected to the rotating end of the drive motor, and the output end of the reducer is connected to the mounting shaft.
[0011] Furthermore, a push rod is fixedly installed on the outer wall of the mounting bracket.
[0012] Furthermore, the push rod is equipped with a handle.
[0013] Furthermore, a groove is provided on the outer wall of the mounting shaft for the top screw to enter.
[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a rapid treatment device for highway cracks in highway engineering, which has the following beneficial effects:
[0016] This rapid crack treatment device for highway engineering features two adjustable mounting plates that slide along an axial direction on a mounting shaft. Each mounting plate has brushes on its outer periphery, allowing the spacing between the brushes to be flexibly adjusted according to the actual width of the highway crack. Compared to traditional fixed-width roller brushes that cannot fully adapt to cracks of different widths, this device allows the brushes to penetrate completely into the crack, thoroughly removing residual debris and dust, effectively preventing poor crack sealing quality due to incomplete cleaning.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-6 The present invention discloses a rapid treatment device for highway cracks in highway engineering, comprising a mounting frame 1, a roller 8 at the bottom of the mounting frame 1, a push rod 11 fixedly mounted on the outer wall of the mounting frame 1, and a handle 12 on the push rod 11 to facilitate the movement of the mounting frame 1.
[0026] The mounting bracket 1 houses a mounting shaft 2, on which mounting plates 3 are slidably mounted. Each mounting plate 3 has a brush 4 on its outer periphery. The position of the mounting plates 3 can be adjusted along the axis of the mounting shaft 2 to regulate the spacing between the brushes 4 on both sides. A sleeve 5 is fixedly mounted on the mounting plate 3, fitting over the mounting shaft 2. A set screw 6 is threaded onto the sleeve 5, and its rotating end rests against the outer wall of the mounting shaft 2. A groove 7 is provided on the outer wall of the mounting shaft 2 for the set screw 6 to enter, improving stability. Loosening the set screw and moving the mounting plate adjusts the spacing between the brushes on both sides.
[0027] It also includes a drive motor 9 that provides power for the rotation of the mounting shaft 2. The drive motor 9 and the mounting shaft 2 transmit power through a reducer 10. The input end of the reducer 10 is connected to the rotating end of the drive motor 9, and the output end of the reducer 10 is connected to the mounting shaft 2.
[0028] In summary, this rapid crack treatment device for highway engineering involves loosening the set screw 6 on the sleeve 5, sliding the two mounting plates 3 along the axis of the mounting shaft 2 according to the crack width, adjusting the spacing of the brushes 4 on both sides to match the crack width, tightening the set screw 6 after the spacing is adjusted, fixing the mounting plates 3 on the mounting shaft 2 to prevent positional changes during cleaning, starting the drive motor 9 to rotate the brushes 4, and moving the device along the direction of the highway crack by pushing or pulling to complete the crack cleaning.
