Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway bridge maintenance technology, specifically a highway bridge expansion joint cleaning device. Background Technology
[0002] Expansion joints on highway bridges are expansion devices installed between the ends of two beams, between a beam end and an abutment, or at hinged joints to accommodate bridge deck deformation. Expansion joints are an important component of bridge structures, primarily regulating displacements between the superstructure and the connections between superstructure components caused by vehicle load characteristics and the physical properties of bridge building materials. Currently, common methods for cleaning highway bridge expansion joints include manual cleaning and some simple mechanical equipment. Manual cleaning relies on workers using brooms, shovels, and other tools. This method is not only labor-intensive and inefficient, but the cleaning effect is often unreliable. Furthermore, some cleaning equipment only has sweeping functions, generating large amounts of dust during the process, polluting the environment and potentially harming the health of the operators. Utility Model Content

[0013] 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.
[0014] Example: Figure 1-3As shown, this utility model provides a highway bridge expansion joint cleaning device, including a support frame 11. A push rod 18 is fixedly installed on one side of the support frame 11. Handles are symmetrically fixed on the outer surface of the push rod 18, providing an easy-to-grip and force-applying component for the operator to push or control the movement direction of the device. A drive shaft 12 is rotatably connected to one side of the inner side of the support frame 11, and drive wheels 13 are fixedly sleeved at both ends of the drive shaft 12. A driven wheel 15 is rotatably connected to the other side of the support frame 11. A dust removal mechanism 14 is fixedly installed on one side of the upper surface of the support frame 11. A gasoline engine 20 is fixedly installed on the upper surface of the support frame 11. A first pulley 21 and a second pulley 22 are fixedly sleeved at the output end of the gasoline engine 20. A shaft 23 is rotatably connected to one side of the support frame 11. A sweeping wheel 28 is fixedly connected to one end of the structure. Multiple brushes are fixedly installed on the outer surface of the sweeping wheel 28. The brushes are arranged in a circular array. Their function is to thoroughly clean the expansion joint of the highway bridge by rotating the brushes. The circular array of brushes can fully contact all parts of the expansion joint, effectively removing dust and debris inside the expansion joint, improving cleaning efficiency and quality. A suction head 16 is fixedly installed on the side of the support frame 11 near the sweeping wheel 28. A suction pipe 17 is connected through one end of the suction head 16. One end of the suction pipe 17 is fixedly connected to the dust inlet 31. Its function is to create a dust suction channel, so that the dust and debris swept up by the sweeping wheel 28 can be sucked into the dust collection box 30 through the suction head 16 and the suction pipe 17, thereby achieving effective collection of dust and debris at the expansion joint and ensuring that the dust removal mechanism 14 can realize its dust suction function. A third pulley 24 is fixedly sleeved on the outer surface of shaft 23. The outer surface of the third pulley 24 and the outer surface of the first pulley 21 are together sleeved with a first synchronous belt 25. A fourth pulley 27 is fixedly sleeved on one side of the outer surface of drive shaft 12. The outer surface of the second pulley 22 and the outer surface of the fourth pulley 27 are together sleeved with a second synchronous belt 26. The outer surfaces of the first pulley 21, the third pulley 24, the second pulley 22, and the fourth pulley 27 are all treated with anti-slip treatment. The purpose of the anti-slip treatment is to increase the friction between the pulleys and the synchronous belt, prevent slippage during power transmission, and ensure that the power output of the gasoline engine 20 can be stably and efficiently transmitted to components such as the sweeping wheel 28 and the drive wheel 13, ensuring the normal operation of the equipment. When the operator starts the gasoline engine 20, its output shaft drives the first pulley 21 to rotate, which in turn drives the third pulley 24 to rotate through the first synchronous belt 25, thereby driving the sweeping wheel 28 to rotate. The brush on the outer surface of the sweeping wheel 28 sweeps the expansion joints, sweeping up dust, debris, etc. Meanwhile, the output shaft of the gasoline engine 20 also drives the second pulley 22 to rotate via the second synchronous belt 26. The second pulley 22 drives the fourth pulley 27 to rotate via the second synchronous belt 26. The fourth pulley 27 drives the drive shaft 12 and the drive wheels 13 at both ends to rotate, and the drive equipment moves on the expansion joint.
[0015] The dust removal mechanism 14 includes a dust collection box 30. A dust inlet 31 is provided on one side of the dust collection box 30. A maintenance door 32 is symmetrically and rotatably connected to the upper surface of the dust collection box 30. Multiple guide rails 33 are fixedly installed on the inner surfaces of both sides of the dust collection box 30. A filter plate 34 is slidably connected to one side of every two guide rails 33. Multiple rollers are rotatably connected between the inner walls of the guide rails 33. The outer surfaces of the multiple rollers slide against the filter plate 34. Their function is to reduce the friction between the filter plate 34 and the guide rails 33 when the filter plate 34 needs to be pulled out for cleaning and maintenance, so that the operation of pulling out and inserting the filter plate 34 is smoother and less laborious, and facilitates the daily maintenance and upkeep of the equipment. Multiple filter screens with different pore sizes are fixedly installed inside the filter plate 34. The filter screens with different pore sizes can perform graded filtration of the dust-laden air drawn into the dust collection box 30, effectively intercepting dust and debris particles of different sizes, ensuring that the discharged air reaches a certain level of cleanliness, and at the same time, collecting dust and debris in the dust collection box 30 for easy subsequent cleaning. The operator starts the dust removal fan 35 and sucks the dust and debris generated during the cleaning process into the dust collection box 30 through the suction head 16 and suction pipe 17. The filter plate 34 in the dust collection box 30 filters the dust-laden air, and the purified air is discharged, while the dust and debris are collected in the dust collection box 30.
[0016] Working principle: The gasoline engine 20 in the equipment serves as the power source, outputting power. Its output end is fixedly fitted with a first pulley 21 and a second pulley 22. When the engine runs, it drives these two pulleys to rotate. The first pulley 21 is connected to a third pulley 24 via a first synchronous belt 25. The third pulley 24 is fixedly fitted onto a shaft 23, one end of which is connected to a sweeping wheel 28. When the first pulley 21 rotates, it drives the third pulley 24 via the first synchronous belt 25, thereby causing the shaft 23 and the sweeping wheel 28 to rotate. The brushes on the outer surface of the sweeping wheel 28 are arranged in a circular array, which can clean the bridge expansion joints, sweeping away dust and debris. The second pulley 22 is connected to a fourth pulley 27 via a second synchronous belt 26. The fourth pulley 27 is fixedly fitted onto a drive shaft 12, with drive wheels 13 fixedly fitted at both ends of the drive shaft 12. When the second pulley 22 rotates, it drives the fourth pulley 27 via the second synchronous belt 26, causing the drive shaft 12 and drive wheel 13 to rotate, thereby realizing the movement of the equipment. The driven wheel 15 plays a role in auxiliary support and movement guidance; during the cleaning process of the sweeping wheel 28, dust and debris are stirred up. The suction head 16 is close to the cleaning position and is connected to the dust inlet 31 of the dust collection box 30 through the suction pipe 17. After the dust removal fan 35 is started, a negative pressure is formed in the dust collection box 30, and air, dust, and debris are sucked into the dust collection box 30 through the suction head 16 and the suction pipe 17. Guide rails 33 are installed on the inner surfaces of both sides of the dust collection box 30, and filter plates 34 are slidably connected on the guide rails 33. Multiple filter screens with different pore sizes are fixedly installed inside the filter plates 34. After dusty air enters the dust collection box 30, dust and debris are intercepted by the filter screen, and clean air is discharged from the outlet 36 through the dust removal fan 35. The dust collection box 30 is equipped with an inspection door 32. When it is necessary to clean the dust and debris intercepted on the filter screen, the inspection door 32 can be opened to remove the filter plate 34 from the guide rail 33 for cleaning and maintenance. The operator can push or control the movement direction of the equipment by holding the handle on the push rod 18, so that the equipment can move on the bridge expansion joint to complete the cleaning work of the entire expansion joint.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
