Description

Technical Field

[0001] This utility model relates to the field of highway subgrade technology, specifically a highway subgrade drainage ditch cleaning device. Background Technology

[0002] The roadbed is the foundation structure beneath the road surface. It bears the traffic load transmitted from the road surface and diffuses it into the deep soil layer. It is a key part to ensure the stability and safety of the road. Once the drainage ditches of the roadbed become blocked, water will continue to seep into the roadbed, causing the water content of the roadbed soil to increase and the strength to decrease significantly. This will lead to roadbed settlement and collapse, as well as road surface defects such as pumping and potholes. This not only seriously affects the service life of the road but also poses a great threat to driving safety.

[0003] However, existing technologies still have the following problems:

[0004] First, most existing highway subgrade drainage ditch cleaning devices are not suitable for dealing with drainage ditches of different widths. They lack adjustable cleaning mechanisms and cannot flexibly adjust the position of cleaning components according to the width of the drainage ditch. This greatly limits the applicability of the equipment and often makes it difficult to meet the diverse needs of highway subgrade drainage ditch cleaning.

[0005] Secondly, existing roadbed drainage ditch cleaning devices are usually not comprehensive enough, mostly only able to clean a specific part of the drainage ditch, making it difficult to clean the bottom, sides and corners of the drainage ditch in all directions; moreover, some devices are not equipped with a cleaning liquid spraying system, relying solely on mechanical cleaning, which is not effective in cleaning stubborn dirt.

[0006] To address the aforementioned problems, the inventors have proposed a roadbed drainage ditch cleaning device to solve these issues. Utility Model Content

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.

[0021] Example: Figure 1-4As shown, this utility model provides a roadbed drainage ditch cleaning device, including a support plate 1. A cleaning fluid tank 4 is fixedly mounted on the upper surface of the support plate 1. Universal wheels 11 are symmetrically mounted on the lower surface of the support plate 1. A push handle 12 is symmetrically fixedly mounted on one side of the upper surface of the support plate 1. The push handle 12 adopts an ergonomic design and is covered with anti-slip rubber material to increase the friction between the worker's hand and the push handle, reducing fatigue caused by prolonged holding. A control plate 13 is fixedly mounted on the upper surface of the cleaning fluid tank 4. An adjustment frame 2 is provided on one side of the support plate 1, and two connecting rods 26 are fixedly mounted between the adjustment frame 2 and the upper surface of the support plate 1. Universal wheels 11 The design of 1 and push handle 12 greatly improves the mobility of the equipment. Workers can easily push the equipment and move it between roadbed drainage ditches in different sections of the road, quickly respond to cleaning needs, reduce time waste caused by inconvenient equipment movement, and improve the overall efficiency of cleaning work. Workers can operate the start and stop of each motor of the equipment and the opening and closing of the solenoid valve 41 on the control panel 13. Before starting the cleaning operation, parameters such as the speed of each motor and the spray flow rate of the cleaning fluid can be preset on the control panel 13 to ensure that the cleaning operation is carried out according to the set requirements. The operation of the control panel 13 is a mature technology and will not be described in detail.

[0022] A bidirectional lead screw 21 is rotatably mounted inside the adjusting frame 2. The lead screw surface is manufactured using a high-precision grinding process to improve thread accuracy and reduce wear. A first motor 22 is fixedly mounted on the outer surface of the adjusting frame 2. The output end of the first motor 22 passes through the adjusting frame 2 and is fixedly connected to the bidirectional lead screw 21. Connecting blocks 23 are symmetrically threaded at different thread positions on the outer surface of the bidirectional lead screw 21. A sliding groove 24 is formed on the upper surface of the adjusting frame 2. A slider 25 is fixedly mounted on the upper surface of the connecting block 23 and is engaged within the sliding groove 24. A limiting post 27 is fixedly mounted inside the adjusting frame 2 and passes through the connecting block 23. A vertical plate 3 is fixedly installed on the lower outer side. When the first motor 22 is started, its output end drives the bidirectional lead screw 21 to rotate. Since the threads on the outer surface of the bidirectional lead screw 21 have different directions of rotation, the two connecting blocks 23 that are threaded with it will move towards or away from each other along the bidirectional lead screw 21. During this process, the slider 25 on the connecting block 23 slides in the groove 24 on the upper surface of the adjusting frame 2, which plays a guiding role and prevents the connecting block 23 from rotating. At the same time, the limiting post 27 passes through the connecting block 23, further ensuring that the connecting block 23 moves smoothly, thereby realizing the precise adjustment of the position of the vertical plate 3 to adapt to the drainage ditches of different widths of highway subgrade.

[0023] Two vertical plates 3 are symmetrically mounted with mounting shafts 31 on their inner sides, and a lower cleaning shaft 32 is detachably mounted between the two mounting shafts 31. A second motor 33 is fixedly mounted on the outer side of one of the vertical plates 3. The output end of the second motor 33 passes through the vertical plate 3 and is fixedly connected to the corresponding mounting shaft 31. Two support blocks 34 are fixedly mounted on the outer surface of the vertical plate 3, and a side cleaning shaft 35 is rotatably mounted between the two support blocks 34. The surfaces of the lower cleaning shaft 32 and the side cleaning shaft 35 are provided with spiral bristles made of high-strength nylon material, which has good flexibility and cleaning ability. A third motor 36 is fixedly installed on the upper surface of the side support block 34. The output end of the third motor 36 passes through the corresponding support block 34 and is fixedly connected to the side cleaning shaft 35. A corner scraper 37 is fixedly installed on one side of the vertical plate 3. When the vertical plate 3 reaches the appropriate position, the second motor 33 and the third motor 36 are started. The second motor 33 drives the mounting shaft 31 to rotate, which in turn causes the lower cleaning shaft 32 to rotate at high speed to clean the bottom of the drainage ditch. The third motor 36 drives the side cleaning shaft 35 to rotate to clean the side of the drainage ditch. The corner scraper 37 can clean the dirt at the corners of the drainage ditch.

[0024] The mounting shaft 31 has a slot 321 on its inner side. The two ends of the lower cleaning shaft 32 are symmetrically fixed with insert plates 322, which are inserted into the corresponding slots 321. The outer surface of the mounting shaft 31 is symmetrically fixed with locking blocks 323, and the locking blocks 323 are connected to the corresponding insert plates 322 by bolts. When the two vertical plates 3 need to be adjusted to the spacing of the corresponding drainage ditch size, or when the lower cleaning shaft 32 is worn or needs to be replaced with a different type of cleaning shaft, the bolts between the locking blocks 323 and the insert plates 322 can be unscrewed, and the insert plates 322 can be pulled out of the slots 321 to achieve quick disassembly and replacement of the lower cleaning shaft 32. This facilitates the replacement of the lower cleaning shaft 32 structure with one suitable for the drainage ditch size and also facilitates equipment maintenance.

[0025] A cover 46 is fitted onto the upper surface of the cleaning liquid tank 4. A solenoid valve 41 is connected to one side of the cleaning liquid tank 4. A delivery pipe 42 is provided on one side of the solenoid valve 41. A diversion pipe 43 is fixedly provided at the lower end of the delivery pipe 42. Several nozzles 44 are fixedly provided on the lower surface of the diversion pipe 43. A reinforcing rod 45 is fixed between the diversion pipe 43 and the delivery pipe 42 and the adjusting frame 2. During the cleaning process, the solenoid valve 41 is opened, and the cleaning liquid in the cleaning liquid tank 4 is sprayed out from the nozzles 44 through the delivery pipe 42 and the diversion pipe 43 to help remove stubborn dirt and improve the cleaning effect.

[0026] Working principle: The design of the casters 11 and push handle 12 greatly improves the mobility of the equipment. The staff can easily push the equipment to move between the roadbed drainage ditches of different road sections, quickly respond to cleaning needs, reduce the time wasted due to the inconvenience of equipment movement, and improve the overall efficiency of cleaning work. The staff can operate the start and stop of each motor of the equipment and the opening and closing of the solenoid valve 41 on the control panel 13. Before starting the cleaning operation, the speed of each motor and the spray flow rate of the cleaning fluid can be preset on the control panel 13 to ensure that the cleaning operation is carried out according to the set requirements.

[0027] When the first motor 22 is started, its output end drives the bidirectional lead screw 21 to rotate. Since the threads on the outer surface of the bidirectional lead screw 21 are rotated in different directions, the two connecting blocks 23 that are threaded together with it will move towards or away from each other along the bidirectional lead screw 21. During this process, the slider 25 on the connecting block 23 slides in the groove 24 on the upper surface of the adjusting frame 2, which plays a guiding role and prevents the connecting block 23 from rotating. At the same time, the limiting post 27 passes through the connecting block 23, further ensuring that the connecting block 23 moves smoothly, thereby realizing the precise adjustment of the position of the vertical plate 3 to adapt to the drainage ditch of the roadbed of different widths.

[0028] Once the vertical plate 3 reaches the appropriate position, the second motor 33 and the third motor 36 are started. The second motor 33 drives the mounting shaft 31 to rotate, which in turn causes the lower cleaning shaft 32 to rotate at high speed to clean the bottom of the drainage ditch. The third motor 36 drives the side cleaning shaft 35 to rotate to clean the sides of the drainage ditch. The corner scraper 37 can clean the dirt at the corners of the drainage ditch.

[0029] When the spacing between the two vertical plates 3 needs to be adjusted to match the size of the drainage ditch, or when the lower cleaning shaft 32 is worn or needs to be replaced with a different type of cleaning shaft, the bolts between the locking block 323 and the insert plate 322 can be unscrewed, and the insert plate 322 can be pulled out of the slot 321 to achieve quick disassembly and replacement of the lower cleaning shaft 32. This facilitates the replacement of the lower cleaning shaft 32 structure with one suitable for the size of the drainage ditch, and also makes equipment maintenance easier.

[0030] During the cleaning process, the solenoid valve 41 is opened, and the cleaning liquid in the cleaning liquid tank 4 is sprayed out from the nozzle 44 through the delivery pipe 42 and the diversion pipe 43 to help remove stubborn dirt and improve the cleaning effect.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. 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.
