Description

Technical Field

[0001] This utility model relates to the field of bridge expansion joint cleaning, specifically an automatic cleaning device for slag accumulation in bridge expansion joints. Background Technology

[0002] A bridge is a structure built to allow roads to cross natural or man-made obstacles. It is erected across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. According to the structural system, there are four basic systems of bridges: beam bridges, arch bridges, rigid frame bridges, and suspension bridges (suspension bridges and cable-stayed bridges). Currently, the method of manually cleaning debris in bridge expansion joints is used, which has the problems of being time-consuming, labor-intensive, incomplete, and inefficient.

[0003] Existing patent (publication number: CN213867565U) discloses a bridge expansion joint cleaning device, comprising an outer body, a back plate fixedly connected to the inner side of the outer body, a motor fixedly connected to one side of the back plate, a first transmission wheel fixedly connected to the output end of the motor, a first belt drivingly connected to the outer surface of the first transmission wheel, and a second transmission wheel drivingly connected to the other end of the first belt. This bridge expansion joint cleaning device, through the arrangement of a motor, handle, and cleaning device, allows the device to move back and forth via the handle during operation. The motor drives the cleaning device to remove debris from the expansion joint, improving cleaning efficiency and saving labor costs. Through the arrangement of a dust collection box, clean water, a fan, a filter screen, and a dust collection hood, during operation, the fan draws debris into the dust collection box, where debris particles settle in the clean water. The filter screen prevents debris from entering the fan, protecting both the fan and the environment.

[0004] However, existing cleaning rollers have fixed positions, making them unsuitable for bridge expansion joints of varying depths. Furthermore, the cleaning rollers are ineffective at removing debris stuck within the expansion joints. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: Automatic debris removal device for bridge expansion joints, see [link / reference] Figures 1 to 5 ,include:

[0032] Vehicle body 2;

[0033] An adjustment component is located on one side of the vehicle body 2;

[0034] The adjustment component includes:

[0035] Mounting frame 1 has a cleaning mechanism on its inner side, which is used to clean impurities in the bridge expansion joint;

[0036] A vertical adjustment mechanism, mounted on mounting bracket 1, is used to adjust the height of the cleaning mechanism;

[0037] The drive mechanism, located on the side of the mounting bracket 1, is used to drive the cleaning mechanism to rotate.

[0038] This device, through its adjustable components, cleaning mechanism, vertical adjustment mechanism, and drive mechanism, achieves the following during use:

[0039] Adaptive depth adjustment: The height of the cleaning mechanism is dynamically adjusted by the vertical adjustment mechanism, so that the bottom of the cleaning mechanism contacts the bottom of the inner cavity of the bridge expansion joint, thereby adapting to bridge expansion joints of different depths and solving the problem of cleaning blind spots caused by the traditional fixed roller brush.

[0040] High-efficiency slag removal: The drive mechanism drives the cleaning mechanism to rotate inside the bridge expansion joint, which enhances the cutting force on stuck impurities and improves the removal effect of stubborn slag.

[0041] For details, see Figure 1 , Figure 3 and Figure 4 The vertical adjustment mechanism includes slide grooves 17 on both sides of the mounting frame 1. Slider blocks 18 are slidably connected in both slide grooves 17. A lead screw 61 is rotatably connected between the upper and lower ends of the inner cavity of one of the slide grooves 17 through a bearing. The slider 18 on the side closer to the lead screw 61 is threaded onto the outside of the lead screw 61. A first drive motor 6 is fixedly installed on the top of the mounting frame 1. The drive end of the first drive motor 6 rotates through the mounting frame 1 and is connected to the lead screw 61 through a coupling. The first drive motor 6 replaces manual adjustment, improving work efficiency and safety. The lead screw 61 transmission enables millimeter-level height adjustment, ensuring that the cleaning mechanism accurately aligns with the expansion joint.

[0042] Further, see Figure 3The cleaning mechanism includes a cleaning roller 12, with multiple blades 13 fixedly connected to the outer side of the cleaning roller 12. A connecting shaft 110 is fixedly passed through the center of the cleaning roller 12. The connecting shaft 110 is rotatably connected between the two sliders 18 through bearings. The blades 13 increase the cutting force of the impurities stuck in the bridge expansion joint, thus avoiding the residue of impurities caused by cleaning.

[0043] It is worth noting that, see Figure 1 The drive mechanism includes a connecting hole 11 on the mounting bracket 1 at the end away from the lead screw 61, and the connecting hole 11 communicates with the slide groove 17. A connecting block 35 is fixedly connected to the end of the slider 18 near the connecting hole 11. A frame 32 is fixedly connected to the end of the connecting block 35 away from the slider 18. A second drive motor 31 is fixedly installed on the inner side of the frame 32. The drive end of the second drive motor 31 rotates through the connecting block 35 and the slider 18 and is connected to the connecting shaft 110 through a coupling. The external design of the second drive motor 31, in conjunction with the connecting hole 11, avoids interference with the height adjustment of the cleaning mechanism and facilitates the heat dissipation and maintenance of the second drive motor 31.

[0044] It is worth noting that, see Figure 1 and Figure 4 The mounting bracket 1 has a through hole 14 on one side, which communicates with the slide groove 17. A connecting plate 19 is fixedly connected to one end of the slider 18 near the through hole 14. A rotating shaft 16 is rotatably connected to the connecting plate 19 via a bearing. A cleaning roller 15 is fixedly connected to the outer side of the rotating shaft 16. The bottom of the cleaning roller 15 is on the same horizontal line as the bottom of the blade 13. One end of the rotating shaft 16 rotatably passes through the connecting plate 19. A first sprocket 3 is fixedly connected to the rotating shaft 16 on the outer side of the connecting plate 19. A second sprocket 33 is fixedly connected to the outer side of the drive end of the motor 6. A chain 34 meshes between the second sprocket 33 and the first sprocket 3. The cleaning roller 15 is synchronously adjusted with the cleaning roller 12 through the connecting plate 19. The first drive motor 6 drives the cleaning roller 12 and the cleaning roller 15 at the same time, reducing energy consumption and cost. After the cleaning roller 12 rotates and works with the blade 13 to clean the bridge expansion joint, the cleaning roller 15 is used to clean the cleaned area to ensure that there is no residual residue, thus forming a dual cleaning mode of "coarse cleaning + fine cleaning".

[0045] It is worth mentioning that, see Figure 1 The top outer sides of the cleaning roller 12 and the sweeping roller 15 are both covered with protective covers 4. The two protective covers 4 are fixedly connected to each other and are fixedly connected to the connecting plate 19. The protective covers 4 prevent the rotating parts from being exposed and causing injury to personnel or foreign objects from being caught in, and also prevent debris from flying during the cleaning process, keeping the working environment clean.

[0046] It is worth noting that, as shown in Figure…, the vehicle body 2 includes a collection box 21, located at the end away from the mounting frame 1. A filter plate 51 is fixedly connected to the inner cavity of the collection box 21. A suction pipe 5 is connected between the collection box 21 and the protective cover 4 above the cleaning roller 15. The connection point between the suction pipe 5 and the collection box 21 is lower than the height of the filter plate 51. A negative pressure pump 52 is fixedly connected to one end of the collection box 21. An air suction pipe 53 is connected between the negative pressure pump 52 and the side of the collection box 21. When cleaning the bridge expansion joint, the negative pressure pump 52 is activated to directly suck away debris during the cleaning process, avoiding secondary pollution of the bridge surface. The filter plate 51 structure ensures that only clean air enters the negative pressure pump 52, extending the equipment life. Furthermore, the low-position arrangement of the suction pipe 5 utilizes gravity-assisted dust collection, reducing energy consumption.

[0047] It is worth mentioning that, see Figure 1 , Figure 2 and Figure 5 The collection box 21 is open at the end away from the cleaning roller 15. A sealing plate 24 is provided at the opening of the collection box 21. A bolt 22 is rotatably passed through the sealing plate 24 and is threaded to the surface of the collection box 21. A handle 23 is fixedly connected to one end of the sealing plate 24. With the setting of the bolt 22, the sealing plate 24 can be opened without tools to pour out the accumulated residue, which greatly improves maintenance efficiency.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
