[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a bridge expansion joint cleaning device. Background Technology

[0002] Bridges expand and contract with temperature changes, which can severely affect the bridge structure. To mitigate this effect, expansion joints are typically installed on bridges. These joints expand and contract with the bridge structure as it expands and contracts with temperature changes, thereby reducing stress on the bridge.

[0003] However, expansion joints are prone to accumulating debris, affecting their use and requiring regular cleaning of particles or dirt. Current cleaning methods typically involve regular manual cleaning by workers, but this is inefficient and poses a safety risk, especially during construction work in the middle of the bridge deck.

[0004] Therefore, a bridge expansion joint cleaning device is needed to improve cleaning efficiency while avoiding manual cleaning on the road surface and improving safety. Utility Model Content

[0005] The purpose of this invention is to provide a bridge expansion joint cleaning device to solve the problems existing in the background art.

[0006] The objective of this utility model is achieved through the following technical solution: A bridge expansion joint cleaning device includes a mobile trolley, a sweeping component, and a vacuuming component. The sweeping component is located at the front end of the mobile trolley and is connected to the mobile trolley via a pitching component.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See Figures 1-4 This utility model provides a technical solution: like Figures 1-4 As shown, a bridge expansion joint cleaning device includes a mobile trolley 1, a sweeping component, and a vacuuming component. The mobile trolley 1 has a built-in power component, a remote control module, and a power supply component. The power supply component supplies power to the power component, thereby driving the mobile trolley 1 to move. The mobile trolley 1 is a common remote-controlled trolley and will not be described in detail. The mobile trolley 1 adopts a remote control mode and can be remotely controlled via a remote control or a mobile phone through the remote control module. This eliminates the need for manual pushing of the trolley on the road surface for cleaning, greatly ensuring the safety of operators.

[0021] A cleaning component is installed at the front end of the mobile trolley 1 to clean debris from the expansion joint. Specifically, the cleaning component is connected to the mobile trolley 1 via a tilting component. The tilting component includes a connecting arm 41 and a telescopic cylinder 42. One end of the connecting arm 41 is rotatably connected to the mobile trolley 1, and one end of the telescopic cylinder 42 is movably connected to the connecting arm 41. The other end of the telescopic cylinder 42 is also movably connected to the mobile trolley 1. The extension and retraction of the piston rod of the telescopic cylinder 42 causes the connecting arm 41 to rotate around its hinge point with the mobile trolley 1, thereby raising or lowering the connecting arm 41. During cleaning, the tilting component lowers the cleaning component to the expansion joint for easy cleaning; when not in use, the ventilated connecting arm 41 raises the cleaning component to facilitate the normal movement and storage of the mobile trolley 1.

[0022] Specifically, the cleaning assembly includes a cleaning roller 21, a protective shell 22, and a belt drive assembly 23. The motor end of the belt drive assembly 23 is fixed to the upper end of the connecting arm 41. The belt drive assembly 23 is connected to one side of the cleaning roller 21 via a belt. The belt drive assembly 23 drives the cleaning roller 21 to rotate, thereby cleaning the debris in the expansion joint. The width of the cleaning roller 21 is consistent with the width of the expansion joint.

[0023] Meanwhile, a protective shell 22 is set on the outside of the sweeping roller 21. The protective shell 22 is connected to the connecting arm 41. The sweeping roller 21 is located inside the protective shell 22 and is rotatably connected to the protective shell 22. By setting the protective shell 22, the debris swept by the sweeping roller 21 is prevented from flying out randomly, ensuring that the debris swept by the sweeping roller 21 flies out along the tangent of the roller rotation and flies towards one end of the moving trolley 1, so that the vacuuming component located at the rear can collect it.

[0024] Furthermore, such as Figure 2 As shown, the protective shell 22 extends from the bottom of the sweeping roller 21, making it easy for the sweeping roller 21 to contact the expansion joint for cleaning, and preventing interference or collision with the ground due to the excessive length of the protective shell 22.

[0025] Furthermore, the bottom of the protective shell 22 is provided with a flexible rubber plate 24, and two sets of the flexible rubber plates 24 are located on both sides of the protective shell 22 along the forward direction. When the protective shell 22 is lowered to contact the ground by the pitching assembly, the lowest point of the flexible rubber plate 24 is ensured to be lower than the lowest point of the sweeping roller 21, so that the bottom of the shell 22 can be protected by the flexible rubber plate 24 to avoid wear and tear on the protective shell 22. At the same time, the flexible rubber plate 24 is in close contact with the ground on both sides of the expansion joint, so that the swept debris will not fly out to both sides of the expansion joint, which facilitates subsequent collection.

[0026] Furthermore, the vacuuming assembly includes a vacuum hood 31, a vacuum pump, and a collection box. The vacuum hood 31 is fixed to the lower end of the connecting arm 41 and located behind the cleaning assembly. The vacuum pump and the collection box are located inside the mobile trolley 1.

[0027] By placing the dust hood 31 behind the protective shell 22, the debris swept out by the cleaning roller 21 enters the protective shell and is then sucked into the collection box by the dust pump.

[0028] Furthermore, such as Figure 3 As shown, the bottom of the dust hood 31 is provided with brushes 32 on the three sides other than the side facing the protective shell 22. The bottom surface of the brushes 32 is at the same level as the bottom surface of the flexible rubber plate 24.

[0029] Through the above technical solution, debris exiting the protective shell 22 will enter the dust collection hood 31. At the same time, due to the blocking effect of the brush 32, the debris will not leave the dust collection hood 31, making it convenient for the vacuum pump to pick up the debris. Meanwhile, the brush 32 can also sweep the floor, and the swept dust is also in the dust collection hood 31 for easy suction.

[0030] Furthermore, the side of the dust hood 31 facing the mobile trolley 1 is provided with a flexible corrugated pipe 33, and the dust hood 31 is connected to the dust pump through the flexible corrugated pipe 33.

[0031] Through the above technical solution, the flexible corrugated tube 33 facilitates the synchronous tilting of the dust hood 31 when the connecting arm 41 tilts up and down. Both the cleaning component and the dust hood 31 are connected to the connecting arm 41, which facilitates synchronous operation.

[0032] Furthermore, such as Figure 4 As shown, the dust collection hood 31 is connected to the protective shell 22, and the end of the flexible rubber plate 24 is connected to the brush 32. This allows debris inside the protective shell 22 and the flexible rubber plate 24 to enter the dust collection hood 31 after cleaning, further preventing debris from splashing and ensuring effective cleaning and collection.

[0033] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
