Description

Technical Field

[0001] The utility model belongs to the technical field of expansion joint cleaning, in particular to a device for quickly cleaning expansion joints. Background Art

[0002] Bridge expansion joints are a crucial component of bridge structures. To accommodate bridge deck deformation, they are typically installed between beam ends, between beam ends and abutments, or at hinged joints. These joints must be able to expand and contract freely in both directions parallel and perpendicular to the bridge axis, be secure and reliable, and ensure smooth, no jerking or noise-causing traffic. Debris such as fallen leaves, branches, mud, sand, and small stones can easily become lodged in expansion joints. Failure to promptly remove these debris can not only affect their function but can also severely damage their edges and even harm the bridge itself.

[0003] Currently, manual cleaning is used to clean the debris in the expansion joint, but there are no special cleaning tools. In most cases, simple wood chips, iron hooks, etc. are used to pick out the debris and then clean it with a small broom. It is impossible to clean the debris in the expansion joint in one go, and the expansion joint needs to be cleaned multiple times at multiple points. This method has the disadvantages of being time-consuming and labor-intensive, not cleaning thoroughly, and having low work efficiency. Utility Model Content

[0027] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0028] See also Figures 1 to 5The utility model provides a device for quickly cleaning expansion joints, including a brush head 1, a connecting member 2, and a handle 3. The brush head 1 and the handle 3 are fixedly connected by the connecting member 2. The brush head 1 is divided into a first brush head 11 and a second brush head 12, and the first brush head 11 and the second brush head 12 are vertically connected to each other; the brush head 1 is in a "cross" or "T" shape as a whole (the "cross" or "T" shaped brush head 1 is convenient for repeatedly cleaning garbage inside the expansion joint, and sweeps away impurities piled on both sides of the expansion joint, thereby improving cleaning efficiency); the connecting member 2 and the handle 3 are fixed by bolts, threads or welding (the fixation is more stable, preventing the handle 3 from loosening or falling when cleaning garbage, and the brush head 1 or the handle 3 can be replaced in time according to different needs or when damaged); The brush head 1 includes bristles 7 and a bracket 6, and the bracket 6 is fixedly connected to the connecting member 2. The bristles 7 of the first brush head 11 are "V"-shaped, and the second brush head 12 is shorter than the bristles 7 of the first brush head 11 (the V-shaped bristles 7 of the first brush head 11 need to extend into the expansion joint to facilitate the device to clean back and forth inside the expansion joint. The bristles 7 of the second brush head 12 are responsible for cleaning the sides of the expansion joint and the accumulated impurities, so the second brush head 12 needs to be shorter than the bristles 7 of the first brush head 11); a grip 4 is provided at the end of the handle 3 (the grip 4 increases comfort, provides better support during operation, and is also convenient for hanging and storage); the bristles 7 can be made of a wire brush, which increases the cleaning ability of the device, facilitates the cleaning of harder and difficult-to-sweep impurities, and also increases the service life of the brush head 1.

[0029] In this embodiment, please refer to Figures 1 to 2 When in use, the staff holds the handle 3, inserts the first brush head 11 into the expansion joint, and starts cleaning. When encountering a difficult-to-clean area, they can repeatedly clean back and forth until it is clean. At the same time, the second brush head 12 will also clean up the debris piled on both sides of the expansion joint. There is no need to go back and forth multiple times, which effectively improves the working efficiency of the bridge expansion joint.

[0030] In this embodiment, please refer to Figure 3 The handle 3 is a telescopic rod, which is a self-locking telescopic rod that can be directly extended or retracted for easy use. The staff can adjust the length of the telescopic rod as needed to facilitate cleaning of debris in the expansion joint, saving time and effort.

[0031] In this embodiment, please refer to Figures 4 and 5The first brush head 11 is a fixed brush head, and the second brush head 12 is a movable brush head. The movable brush head includes a sliding member 5 and a locking member 51. The sliding member 5 is slidably connected to the handle 3, and the locking member 51 is arranged on the handle 3. The sliding member 5 drives the second brush head 12 to move up and down, so that the first brush head 11 can adapt to expansion joints of different depths. When the second brush head 12 moves to a suitable position, the sliding member 5 is fixed by the locking member 51 on the handle 3; a limiting hole 52 is provided on the sliding member 5, and the locking member 51 is an elastic limiting member. The movable brush head is fixed by the locking member 51 through the limiting hole 52 opened on the sliding member 5. The locking member 51 can be a bolt, a latch or the like, or an elastic limiting member with an elastic protrusion with a compression spring. When fixed, the elastic limiting member can be stuck in the limiting hole 52. When the second brush head 12 slides up and down, the elastic limiting member shrinks in the handle 3. During use, a worker holds the handle 3 and moves the device to the location of the bridge expansion joint. The worker then aligns the first brush head 11 with the expansion joint and places it inside the joint. The worker then adjusts the position of the second brush head 12 according to the joint's depth, moves the slider 5 up and down to completely clean the joint, and then secures the second brush head 12 to begin cleaning. This ensures that impurities in expansion joints of varying depths are cleaned, eliminating the need to change tools and perform multiple cleanings, thereby improving cleaning efficiency.

[0032] In summary, the rapid expansion joint cleaning device of the utility model effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.
