Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge expansion joints, and in particular to a bridge expansion joint cleaning device. Background Technology
[0002] As a key component of bridge structure, bridge expansion joints primarily function to accommodate deformations caused by factors such as temperature changes, vehicle loads, and foundation settlement, ensuring the stability of the bridge structure and traffic safety. During long-term bridge operation, expansion joints are prone to accumulating debris such as mud, gravel, fallen leaves, and domestic waste, as well as retaining rainwater.
[0003] If these debris are not cleaned up in time, they will cause blockage of the expansion joint, preventing it from performing its deformation adjustment function properly, which in turn will lead to problems such as aging and damage of the expansion joint rubber strip and corrosion of the steel.
[0004] A search revealed Chinese Patent Publication No. CN223226531U, which discloses a bridge expansion joint cleaning device. Belonging to the field of expansion joint technology, this device addresses the problem that dust adheres to the inner wall of the expansion joint due to water accumulation, making it difficult to remove. The device includes a base plate with an adjustment mechanism at its top. A first motor is mounted on one side of the top of the base plate, and a connecting shaft is fixedly installed at the bottom output end of the first motor. A mounting block is located at the bottom of the connecting shaft, and a mounting groove is formed at the top of the mounting block. The connecting shaft is movably inserted into the mounting groove. This invention, through the arrangement of the first motor, connecting shaft, mounting block, cleaning rod, and brush, facilitates the cleaning of the inner wall and bottom wall of the bridge expansion joint. The installation groove, limiting groove, receiving groove, spring, movable block, and limiting post facilitate the installation and disassembly of the cleaning rod, allowing for easy replacement with a suitable cleaning device for expansion joints of different sizes.
[0005] Although the device has some improvements and makes it easier to replace the cleaning rod to suit expansion joints of different sizes, it is relatively troublesome to disassemble and assemble. In addition, the device is limited by a spring, and during cleaning, it rotates and generates centrifugal force. Under the influence of centrifugal force, the spring cannot remain stable, which in turn affects the stability of the cleaning rod and affects the cleaning effect. Utility Model Content

[0040] Reference Figures 1-3The collection component 4 includes a suction pump 42, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The suction pump 42 is set on the upper surface of the bucket cover 3. A drain pipe 41 is fixedly installed on the right end of the suction pump 42, and a connecting pipe 43 is fixedly connected to the left end of the suction pump 42. A connecting block 45 is fixedly connected to the right surface of the slide plate 64. A suction pipe 46 is fixedly installed at the end of the connecting pipe 43 away from the suction pump 42 through a clamp 44. The suction pipe 46 is a rigid pipe. The clamp 44 is fitted on the outer wall of the connecting pipe 43. The connecting pipe 43 is a flexible hose that can be flexibly deformed. The suction pipe 46 penetrates and is fixedly connected to the inner surface of the connecting block 45. The suction pipe 46 penetrates the inner surface of the cart 1.
[0041] Working principle: When using this device, first push the trolley 1 to the bridge expansion joint, and then adjust the spacing of the two sets of cleaning brushes 53 according to the width of the bridge expansion joint. During adjustment, rotate the screw 55 to drive the fixed block 56 and the sliding ring 57 to move longitudinally, which in turn drives the two sets of connecting rods 58 to pull or squeeze the cleaning brushes 53, so that the cleaning brushes 53 move closer or expand to fit the width of the bridge expansion joint. When the adjustment is appropriate, loosen the screw 55.
[0042] Then, start motor 62 to drive screw 63 to rotate, which in turn drives slide plate 64, connecting block 45 and cleaning mechanism to move downward until cleaning brush 52 contacts the bottom of bridge expansion joint. Then, turn off motor 62, and the downward moving connecting block 45 will drive the sewage suction pipe 46 to move down and align with the bottom of bridge expansion joint.
[0043] Then, the second motor 72 is started to drive the rotating shaft 73 to rotate, which in turn drives the first cleaning brush 52 and the second cleaning brush 53 to rotate and clean the bridge expansion joint, dispersing dust and impurities. When the second motor 72 is started, the suction pump 42 is started to suck up the impurities, dust and sewage at the bottom of the bridge expansion joint through the suction pipe 46. These stains will enter the collection bucket 2 through the suction pipe 46, the connecting pipe 43 and the discharge pipe 41 and be collected.
[0044] When the bridge expansion joint cleaning is completed, turn off motor 2 72 and suction pump 42, then start motor 1 62 to drive screw 2 63 to reverse, so that cleaning brush 1 52 and sewage suction pipe 46 can be dislodged from the bridge expansion joint.
[0045] When it is necessary to clean the stains in the collection bucket 2, remove the bucket lid 3, then remove the collection bucket 2 and pour out the stains inside. After pouring out the stains, connect the collection bucket 2 and the trolley 1, and then install the bucket lid 3 on the collection bucket 2.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
