[0002] Bridge expansion joints are expansion joints that are typically installed between two beam ends, between a beam end and an abutment, or at the hinged joints of a bridge to meet the requirements of bridge deck deformation. They are required to be able to freely expand and contract in both directions parallel and perpendicular to the bridge axis, be strong and reliable, and operate smoothly without jerks or noise when vehicles pass over them. Comb-tooth expansion joints are a common type of joint, and they offer both of the aforementioned benefits. However, the grooves between the teeth of the joints are prone to accumulating dust and debris, making subsequent cleaning difficult. To facilitate the cleaning of dust and debris from the grooves, a convenient bridge expansion joint cleaning device has been proposed to address this issue. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figures 1-6 , Figure 1 This is a schematic diagram of the three-dimensional structure of a cleaning device in a specific embodiment of the present utility model; Figure 2 for Figure 1 A cross-sectional view of the internal structure; Figure 3 for Figure 1 A cross-sectional view of the internal structure of the middle mounting shell; Figure 4 for Figure 1 An expanded structural diagram of the first internal thread sleeve and the threaded rod portion; Figure 5 for Figure 3 A partial enlarged view of point A in the middle; Figure 6 for Figure 1 Schematic diagram of the structure of the positioning mechanism.

[0026] The utility model provides a convenient bridge expansion joint cleaning device, which includes a mounting shell 1 and a drive motor 2. The drive motor 2 is fixedly arranged on one side of the mounting shell 1 through a bracket. The output shaft of the drive motor 2 is fixedly connected to a rotating shaft 3 through a coupling, and one end of the rotating shaft 3 extends to the interior of the mounting shell 1 and is rotatably connected to the mounting shell 1. A brush roller 4 is fixedly connected to the surface of the rotating shaft 3 and located inside the mounting shell 1.

[0027] To facilitate adjustment of the support height and width of the brush roller 4, an adjustment frame 5 is fixedly connected to each side of the mounting housing 1. An adjustment plate 6 is slidably connected to the interior of the adjustment frame 5. The outer end of the adjustment plate 6 is rotatably connected to a first internally threaded sleeve 7 via a bearing. A threaded rod 8 is internally threadedly connected to the interior of the first internally threaded sleeve 7. The bottom end of the threaded rod 8 is fixedly connected to a support carriage 9. The threaded connection between the first internally threaded sleeve 7 and the threaded rod 8 allows the vertical height of the support carriage 9 to be adjusted. The sliding connection between the adjustment frame 5 and the adjustment plate 6 allows the horizontal distance between the two support carriages 9 to be adjusted.

[0028] The top of the supporting slide 9 can also be fixedly connected to a limiting slide 11. The adjusting plate 6 is provided with a limiting slide groove 12 that slides with the limiting slide 11. The setting of the limiting slide 11 facilitates the horizontal position limitation of the supporting slide 9 during the up and down adjustment process.

[0029] In addition, a positioning mechanism 10 can be set between the adjustment frame 5 and the adjustment plate 6. The positioning mechanism 10 includes a limiting sliding frame 101, which is fixed to the top of the adjustment frame 5 through a bracket. The internal sliding connection of the limiting sliding frame 101 is provided with a latch plate 102, and the bottom of the latch plate 102 extends and slides to the inside of the adjustment frame 5. A return spring 103 is fixedly connected between the latch plate 102 and the limiting sliding frame 101, and two return springs 103 are arranged symmetrically on the same side. A number of latch grooves 104 for use with the latch plate 102 are equidistantly provided on the top of the adjustment plate 6.

[0030] In order to facilitate the operation of adjusting the cleaning device, the outer surface of the mounting shell 1 can be fixedly connected with a second internally threaded sleeve 13 , and the internal thread of the second internally threaded sleeve 13 is connected with an externally threaded push rod 14 .

[0031] During use, place the brush roller 4 in the comb groove in the metal plate at the top of the expansion joint, then screw the first internal threaded sleeve 7, prompting the threaded rod 8 inside the first internal threaded sleeve 7 to drive the support slide 9 to descend, and the support slide 9 descends and gradually contacts the top support of the metal plates on both sides of the comb groove, then start the drive motor 2, and the drive motor 2 starts to drive the rotating shaft 3 and the brush roller 4 to rotate. The brush roller 4 rotates to clean the debris inside the comb groove, and then pushes the external threaded push rod 14, prompting the external threaded push rod 14 to drive the mounting shell 1 and the brush roller 4 to move and clean. The cleaned debris is cleaned to the flat road surface, and finally concentrated cleaning is performed. When it is necessary to adapt to supporting a comb groove with a wider diameter, the operator pulls the latch plate 102 upward, causing the latch plate 102 to move up and disengage from the latch engagement with the adjustment plate 6, and then pulls the adjustment plate 6 horizontally to cause the support slide 9 to contact the top of both sides of the wider comb groove, and finally resets the latch plate 102, causing the latch plate 102 to pass through the adjustment frame 5 and re-latch into the latch groove 104 inside the adjustment plate 6.

[0032] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
