Description

Technical Field

[0001] This invention relates to the field of environmental protection vehicle cleaning equipment technology, and in particular to a road sweeper cleaning mechanism and cleaning method. Background Technology

[0002] With the current severe environmental degradation, energy conservation, emission reduction, and carbon neutrality measures reflect the country's emphasis on environmental issues. Sanitation equipment plays an important role at this stage, solving numerous environmental problems, replacing traditional manual labor, reducing construction difficulty, ensuring personal safety, improving efficiency, and freeing up labor. Road pollution removal vehicles are a new type of environmentally friendly construction vehicle used for deep cleaning of roads. They are mainly used for removing road pollutants, restoring the function of permeable or drainable asphalt pavements, and removing biochemical pollution and toxic and harmful materials. In the prior art, Chinese Patent Publication No. CN217601311U discloses a road pollution removal vehicle, comprising: a vehicle body; a vehicle travel mechanism mounted on the vehicle body; a road cleaning robot, including a chassis, a robot travel mechanism, and a first suction mechanism, wherein the robot travel mechanism and the first suction mechanism are respectively mounted on the chassis, and the first suction mechanism is used to suction materials on the road surface; a lifting suction platform, including a platform, a lifting mechanism, and a second suction mechanism, wherein the platform is mounted on the vehicle body via the lifting mechanism, and the second suction mechanism is mounted on the platform, and the second suction mechanism is used to suction materials on the road surface; and a power mechanism. In the above technical solution, the road pollution removal vehicle can carry a road cleaning robot and a lifting suction platform, enabling rapid turnover between different work areas, fast response, and good mobility.

[0003] In practical use, a sweeping mechanism is installed at the rear of the road sweeper to clean the road and its edges. However, the existing sweeping mechanisms have the following unresolved problems: 1. The sweeping mechanism is not stable during the lifting process, which makes the road sweeper prone to dragging when moving; 2. When the sweeping mechanism is cleaning the dead corners of the road, the sweeping mechanism cannot move laterally, which prevents the cleaning and suction body from getting close to the dead corners, making it difficult to clean the dead corners. 3. The cleaning suction unit is not effective at cleaning roads; Therefore, the above problems need to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a road sweeper cleaning mechanism and cleaning method, which has the ability to lift and move the cleaning mechanism laterally, and the cleaning mechanism has a good road cleaning effect.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a road sweeper cleaning mechanism and cleaning method, comprising a lifting component, a lateral movement component, and a cleaning and suction body. The lifting assembly includes a mounting side plate and a first hydraulic cylinder. A horizontal column is fixedly connected to the inner side of the mounting side plate, and a first hinge is fixedly installed on the outer side of the horizontal column. An L-shaped column is hinged to the horizontal column via the first hinge. A mounting plate is fixedly connected to the bottom of the L-shaped column, and a screw pin is threaded into the mounting plate. Second hinges are fixedly installed at both ends of the first hydraulic cylinder. An installation groove is opened inside the L-shaped column, and one of the second hinges is hinged inside the installation groove. The lateral movement assembly includes a lateral movement base frame, with linear rails fixedly connected to both sides of the inner wall of the lateral movement base frame. A slide bar is fixedly installed on the top of the cleaning and suction body, extending into the interior of the linear rails and slidably connected to them. A cylinder seat is fixedly installed inside the lateral movement base frame, and a second cylinder is fixedly installed on the outer side of the cylinder seat. Connecting blocks are fixedly connected to both sides of the top of the cleaning and suction body, and the connecting blocks are threadedly connected to the output end of the second cylinder. Lifting rings are fixedly connected to both sides of the lateral movement base frame. A water distribution pipe is fixedly connected inside the cleaning and suction body. A powerful cleaning nozzle is fixedly connected to one end of the water distribution pipe. An air suction pipe is fixedly installed on the top of the cleaning and suction body. A fan is fixedly installed inside the air suction pipe. A flange is fixedly connected to the edge of the top of the cleaning and suction body. A water injection pipe is movably installed inside the flange and is connected to the water distribution pipe.

[0006] By adopting the above technical solution, the mounting side plate is installed onto the base of the sweeper. The L-pillar is hinged to the crossbar via a first hinge. The two ends of the first hydraulic cylinder are connected to the sweeper and the L-pillar respectively via two second hinges. During the extension and retraction of the first hydraulic cylinder, it drives the L-pillar, mounting plate, lateral movement assembly, and cleaning and suction body to move in tandem, achieving the effect of flipping the cleaning and suction body, keeping it parallel to the road. Furthermore, through the linkage of the L-pillar, mounting plate, lateral movement assembly, and cleaning and suction body, the above structure can be lifted when the road surface is not being swept, allowing it to be lifted into the interior of the sweeper. When cleaning dead corners of the road, the second hydraulic cylinder drives the cleaning and suction unit to move laterally. The forward thrust generated by the second hydraulic cylinder causes the cleaning and suction unit to move laterally within the guide rail via the sliding strip. This allows the cleaning and suction unit to approach the dead corners of the road, giving it high flexibility during use and improving the cleaning effect. Water inside the sweeper is injected into the water distribution pipe and the powerful cleaning nozzle through the water injection pipe. The powerful cleaning nozzle washes the road, and the air generated by the fan dries the road. This makes the device highly effective in cleaning the road.

[0007] A further feature of the present invention is that the number of mounting side plates is two, and both mounting side plates are internally threaded with second bolts.

[0008] By adopting the above technical solution, the two mounting side plates are symmetrical to each other, and the two mounting side plates are installed into the interior of the sweeper by two sets of second bolts.

[0009] A further feature of the present invention is that crossbars are fixedly connected to both sides of the cleaning and suction body, and universal pulleys are fixedly installed at the bottom of the crossbars.

[0010] By adopting the above technical solution, when the sweeper moves the cleaning and suction unit, the universal pulleys contact the ground and support the cleaning and suction unit during the movement.

[0011] A further feature of the present invention is that a mounting block is fixedly installed in the middle of the inner wall of the air suction pipe, and a grille is threadedly connected to the top of the mounting block.

[0012] By adopting the above technical solution, the grille is threaded to the inside of the block, and the grille shields the fan to prevent impurities and dust from entering the inside of the suction pipe.

[0013] A further feature of the present invention is that a fan frame is fixedly installed inside the air suction pipe, and the fan is fixedly connected inside the fan frame.

[0014] By adopting the above technical solution, the fan is fixed inside the suction pipe by the fan frame, which improves the stability of the fan during operation.

[0015] A further feature of the present invention is that the slide bar has a groove inside, a limiting wheel is rotatably connected inside the groove, and a limiting rail is fixedly connected to the inner wall of the linear rail.

[0016] By adopting the above technical solution, the limiting wheel is set in the groove inside the slide bar, and the limiting wheel extending to the outside of the groove is slidably connected to the inside of the limiting rail. The limiting rail is straight, which allows the slide bar to move in a straight line.

[0017] A further feature of the present invention is that the number of the powerful cleaning nozzles is several, and the several powerful cleaning nozzles are divided into two groups, with the two groups of powerful cleaning nozzles arranged on the left and right sides of the cleaning and suction body.

[0018] By adopting the above technical solution, two sets of powerful cleaning nozzles are distributed on the left and right sides of the cleaning and suction body, thereby enabling the cleaning of both sides of the road.

[0019] A further provision of the present invention is that the number of the first hydraulic cylinders is two, and the two first hydraulic cylinders are synchronously driven by an encoder.

[0020] By adopting the above technical solution, the two first cylinders are synchronously driven by encoders. An encoder is a device that can convert the rotation angle of a motor into a digital signal output. By collecting and processing the encoder signal, the speed and position of the motor can be controlled.

[0021] A further feature of the present invention is that the number of mounting plates is two, and the two mounting plates clamp the two sides of the cleaning and suction body.

[0022] By adopting the above technical solution, two mounting plates are respectively installed on both sides of the cleaning and suction body, so that the cleaning and suction body is fixed by the two mounting plates.

[0023] Step 1: The lifting assembly flips the lateral movement assembly and the cleaning and suction body, allowing them to be lifted into the interior of the road pollution removal vehicle. Step 2: The lateral movement component drives the cleaning and suction unit to move left and right, allowing the cleaning and suction unit to approach the dead corners of the road. Step 3: The main body of the cleaning and suction unit injects water into the powerful cleaning nozzle through the water distribution pipe, and sprays the road through the powerful cleaning nozzle. The fan inside the suction pipe dries the road. Step 4: Clean the suction unit by moving it with universal pulleys, and isolate impurities inside the suction pipe through a grid.

[0024] The beneficial effects of this invention are: This device uses a lifting component and a lateral movement component to lift and move the cleaning and suction unit. During use, the lifting component flips the cleaning and suction unit to keep it parallel to the ground. After cleaning the road, the lifting component retracts the cleaning and suction unit into the sweeper. The lateral movement component moves the cleaning and suction unit left and right, allowing it to approach and clean hard-to-reach corners of the road. The cleaning and suction unit not only cleans the road but also dries it, making this device highly convenient and effective at cleaning roads. Attached Figure Description

[0029] A road sweeper cleaning mechanism and cleaning method, including the following specific embodiments: Example 1: Please refer to Figure 1-6The lifting assembly 1 includes a mounting side plate 11 and a first hydraulic cylinder 17. A horizontal column 12 is fixedly connected to the inner side of the mounting side plate 11, and a first hinge 13 is fixedly installed on the outer side of the horizontal column 12. An L-column 14 is hinged to the horizontal column 12 through the first hinge 13. A mounting plate 15 is fixedly connected to the bottom of the L-column 14. A screw pin 16 is threaded inside the mounting plate 15. Second hinges 18 are fixedly installed at both ends of the first hydraulic cylinder 17. An installation groove 19 is opened inside the L-column 14, and one of the second hinges 18 is hinged inside the installation groove 19. The transverse component 2 includes a transverse base frame 21. Linear rails 22 are fixedly connected to both sides of the inner wall of the transverse base frame 21. A slide bar 4 is fixedly installed on the top of the cleaning and suction body 3. The slide bar 4 extends into the interior of the linear rails 22 and is slidably connected to the linear rails 22. A cylinder seat 23 is fixedly installed inside the transverse base frame 21. A second cylinder 24 is fixedly installed on the outer side of the cylinder seat 23. Connecting blocks 25 are fixedly connected to both sides of the top of the cleaning and suction body 3. The connecting blocks 25 are threadedly connected to the output end of the second cylinder 24. Lifting rings 26 are fixedly connected to both sides of the transverse base frame 21. A water distribution pipe 5 is fixedly connected inside the cleaning suction body 3. A powerful cleaning nozzle 6 is fixedly connected to one end of the water distribution pipe 5. An air suction pipe 7 is fixedly installed on the top of the cleaning suction body 3. A fan 8 is fixedly installed inside the air suction pipe 7. A flange 9 is fixedly connected to the edge of the top of the cleaning suction body 3. A water injection pipe 10 is movably installed inside the flange 9. The water injection pipe 10 is connected to the water distribution pipe 5. Furthermore, there are two mounting side plates 11, and the interior of each mounting side plate 11 is threaded with a second bolt 27. The interior of the slide bar 4 is provided with a groove, and the interior of the groove is rotatably connected to a limit wheel 33. The inner wall of the linear rail 22 is fixedly connected to a limit rail 34. There are several powerful cleaning nozzles 6, and the several powerful cleaning nozzles 6 are divided into two groups. The two groups of powerful cleaning nozzles 6 are set on the left and right sides of the cleaning suction body 3. There are two first oil cylinders 17, and the two first oil cylinders 17 are synchronously driven by an encoder. There are two mounting plates 15, and the two mounting plates 15 clamp the two sides of the cleaning suction body 3. It should be noted that encoders are common synchronous drive components in the prior art, and will not be discussed in detail in this document; Specifically, the mounting side plate 11 is installed onto the base of the sweeper. The L-pillar 14 is hinged to the crossbeam 12 via the first hinge 13. The two ends of the first hydraulic cylinder 17 are connected to the sweeper and the L-pillar 14 respectively via two second hinges 18. During the extension and retraction process, the first hydraulic cylinder 17 will drive the L-pillar 14, the mounting plate 15, the lateral movement assembly 2, and the cleaning and suction body 3 to work together, achieving the effect of flipping the cleaning and suction body 3, so that the cleaning and suction body 3 remains parallel to the road. The linkage of the main body 3 allows for the lifting of the aforementioned structure when the road surface is not being swept, bringing it into the interior of the sweeper. When cleaning dead corners of the road, the second hydraulic cylinder 24 drives the cleaning and suction body 3 to move laterally. The second hydraulic cylinder 24 generates a forward thrust, causing the cleaning and suction body 3 to move laterally within the rail 22 via the slide bar 4. This allows the cleaning and suction body 3 to approach dead corners of the road, giving it high flexibility during use and improving the road cleaning effect. The water inside the sweeper... Water is injected through the injection pipe 10 into the distribution pipe 5 and the powerful cleaning nozzle 6, which then washes the road. The blower 8 generates air to dry the road, resulting in a highly effective cleaning effect. Two mounting side plates 11 are symmetrical and are installed into the sweeper vehicle using two sets of second bolts 27. A limiting wheel 33 is positioned in a groove inside the slide bar 4, and extends outwards from the groove, slidably connected to the limiting rail 34. The limiting rail 34 is linear. This allows the slide bar 4 to move in a straight line. Two sets of powerful cleaning nozzles 6 are distributed on the left and right sides of the cleaning and suction body 3, which can then clean the left and right sides of the road. The two first hydraulic cylinders 17 are synchronously driven by encoders. An encoder is a device that can convert the rotation angle of a motor into a digital signal output. By collecting and processing the encoder signal, the speed and position of the motor can be controlled. Two mounting plates 15 are respectively mounted on both sides of the cleaning and suction body 3, so that the cleaning and suction body 3 is fixed by the two mounting plates 15. Example 2: Please refer to Figure 1 Both sides of the cleaning and suction body 3 are fixedly connected with crossbars 28, and universal pulleys 29 are fixedly installed at the bottom of the crossbars 28. Specifically, when the sweeper moves the cleaning and suction body 3, the universal pulley 29 contacts the ground and supports the cleaning and suction body 3 during the movement. Example 3: Please refer to Figure 1 and Figure 5A mounting block 30 is fixedly installed in the middle of the inner wall of the suction pipe 7. A grille 31 is threadedly connected to the top of the mounting block 30. A fan frame 32 is fixedly installed inside the suction pipe 7. A fan 8 is fixedly connected inside the fan frame 32. Specifically, the grille 31 is threaded to the inside of the mounting block 30. The grille 31 shields the fan 8 to prevent impurities and dust from entering the inside of the suction pipe. The fan 8 is fixed inside the suction pipe 7 by the fan frame 32, which improves the stability of the fan 8 during operation. A road sweeper cleaning mechanism and cleaning method, comprising the following steps: Step 1: Lifting component 1 flips over the transverse component 2 and the cleaning and suction body 3, so that the transverse component 2 and the cleaning and suction body 3 can be lifted into the interior of the road pollution removal vehicle; Step 2: The lateral movement component 2 drives the cleaning and suction body 3 to move left and right, so that the cleaning and suction body 3 can approach the dead corner of the road; Step 3: The main body of the cleaning and suction unit 3 injects water into the interior of the high-power cleaning nozzle 6 through the water distribution pipe 5, and sprays the road through the high-power cleaning nozzle 6. The fan 8 inside the suction pipe 7 dries the road. Step 4: Clean the suction body 3. It is driven to move by the universal pulley 29. The inside of the suction pipe 7 is isolated from impurities by the grille 31.

[0030] In this invention, the mounting side plate 11 is installed on the base of the sweeper. The L-pillar 14 is hinged to the cross column 12 via the first hinge 13. The two ends of the first hydraulic cylinder 17 are respectively connected to the sweeper and the L-pillar 14 via two second hinges 18. During the extension and retraction process, the first hydraulic cylinder 17 will drive the L-pillar 14, the mounting plate 15, the lateral movement component 2, and the cleaning and suction body 3 to work together, achieving the effect of flipping the cleaning and suction body 3 so that the cleaning and suction body 3 remains parallel to the road. Furthermore, through the linkage of the L-pillar 14, the mounting plate 15, the lateral movement component 2, and the cleaning and suction body 3, the above structure can be lifted when the road surface is not being swept, so that the above structure is lifted into the sweeper's interior. When cleaning dead corners of the road, the second hydraulic cylinder 24 drives the cleaning and suction body 3 to move laterally. The second hydraulic cylinder 24 generates a forward thrust, causing the cleaning and suction body 3 to move laterally inside the rail 22 via the slide bar 4. This allows the cleaning and suction body 3 to approach the dead corners of the road, giving it high flexibility during use and improving the cleaning effect. Water inside the sweeper is injected into the water distribution pipe 5 and the powerful cleaning nozzle 6 through the water injection pipe 10. The powerful cleaning nozzle 6 washes the road, and the air generated by the blower 8 dries the road. This gives the device a strong and effective cleaning effect when cleaning the road.
