Technical Field
[0001] This utility model belongs to the field of guardrail cleaning technology, specifically, it relates to a device that integrates guardrail cleaning and garbage collection. Background Technology
[0002] With the acceleration of urbanization, urban road construction and traffic safety facilities have received significant attention. Guardrails, as a crucial component of road safety facilities, play a vital role in ensuring driving safety, separating lanes, and protecting pedestrians. However, because guardrails are often exposed to the external environment, they are frequently contaminated by dust, dirt, oil, rainwater, and other factors. If the surface of guardrails is not cleaned for a long time, it can become unsightly, affecting not only the city's appearance but also reducing their visibility and compromising road safety.
[0003] Existing guardrail cleaning devices typically only offer a basic cleaning function, focusing primarily on cleaning and failing to effectively collect the debris generated during the cleaning process. This results in debris potentially remaining on the road, affecting road cleanliness and requiring additional personnel and equipment for cleanup, increasing maintenance costs. Furthermore, in actual cleaning operations, due to complex road conditions and the presence of obstacles, existing cleaning devices lack effective obstacle avoidance capabilities, making them prone to collisions or damage in complex environments. Utility Model Content
[0004] In view of this, the present invention provides a device that integrates guardrail cleaning and garbage collection, which can solve the problem that existing guardrail cleaning devices cannot effectively collect the garbage generated during the cleaning process, thus affecting the cleanliness of the road; at the same time, it can solve the problem that existing cleaning devices lack effective obstacle avoidance functions and are prone to collisions or damage in complex environments.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a device integrating guardrail cleaning and garbage collection, comprising a garbage bin, a clean water tank and a water spraying system, a sweeping system, a suction system, and a guardrail cleaning device. The garbage bin is mounted on a sanitation vehicle for storing garbage. The sweeping system is installed on both sides of the sanitation vehicle to sweep the garbage to the edge of the suction nozzle of the suction system. The suction system is connected to the garbage bin and sucks the garbage collected by the sweeping system into the garbage bin. The guardrail cleaning device is fixedly connected to the front end of the sanitation vehicle via a connecting frame for cleaning the guardrail. The clean water tank and water spraying system are installed on the top of the garbage bin for spraying water mist.
[0007] Based on the above technical solution, the device for integrating guardrail cleaning and garbage collection of this utility model can be further improved as follows:
[0008] The suction system includes the nozzle, the fan, and the suction pipe. One end of the suction pipe is connected to the garbage bin, and the other end is connected to the nozzle. The fan is located inside the suction pipe to generate negative pressure.
[0009] Furthermore, the connecting frame is connected to the chassis of the cleaning vehicle by bolts. The end of the connecting frame away from the cleaning vehicle is connected to a cleaning roller via a rotating arm. A fixed seat and a lifting frame are provided between the connecting frame and the rotating arm. The fixed seat is connected to the connecting frame via a hanging plate seat. One end of the lifting frame is connected to a sliding frame, and the other end is connected to the rotating arm. The rotating arm is connected to the cleaning roller. A drive motor is provided at one end of the cleaning roller. The drive motor is used to drive the cleaning roller to rotate to achieve the cleaning operation.
[0010] Furthermore, the fixed base is connected to the sliding frame, and the sliding frame has two sets of slider assemblies arranged at the top and bottom respectively. A moving motor, a rack and a motor gear are installed at the bottom, which is used to make the sliding frame move left and right along the end face of the slide groove when the moving motor drives the motor gear to rotate.
[0011] Limit switches and limit blocks are installed on both sides of the sliding frame to provide double protection, preventing movement out of position and ensuring safe and reliable sliding distance and position.
[0012] Furthermore, the sliding frame and the lifting frame are connected by a swing cylinder, which, under hydraulic drive, enables the guardrail cleaning device to rotate at any angle within 0 to 180°.
[0013] Limit blocks are installed on both sides of the sliding frame to protect against mechanical damage caused by a malfunction of the swing cylinder.
[0014] Furthermore, a left tension spring, a right tension spring, and an adjusting rod are respectively installed on both sides between the lifting frame and the rotating arm to achieve adaptive obstacle avoidance by tightening the spring tension.
[0015] Furthermore, the lifting frame is a parallel four-bar linkage mechanism with a lifting cylinder installed inside, which is used to extend when the cleaning vehicle needs to be moved or stop working to lift the guardrail cleaning device to a designated position.
[0016] When the guardrail cleaning device is working, the sliding frame moves laterally to a designated position, the swing cylinder rotates to a designated position, the lifting cylinder retracts, and the lifting frame lowers the guardrail cleaning device to a suitable working position by its own weight.
[0017] Furthermore, the lower part of the lifting frame is equipped with omnidirectional rollers, which are used to bear and share part of the weight of the guardrail cleaning device; the height of the omnidirectional rollers is adjustable to ensure that the cleaning height or ground clearance of the guardrail cleaning device is consistent and to guide the movement direction of the guardrail cleaning device.
[0018] Furthermore, a bearing seat is installed on the rotating arm, and a rotating rod is rotatably arranged around the bearing seat. A protective cover is fixed on the rotating rod. When the cleaning roller is performing a cleaning operation, water is sprayed onto the cleaning roller and the object being cleaned through the water spray nozzles installed on the lower spray rod and the upper spray rod on both sides of the protective cover.
[0019] The cleaning roller is equipped with cloth bristles. When the cleaning roller rotates and cleans, water will be thrown out by the cloth bristles. The protective cover prevents the thrown water from spreading to the surrounding area.
[0020] The protective cover is provided with the elastic positioning pin, which is used to fix the rotation angle of the protective cover; the lower part of the protective cover is provided with support rollers to ensure the stability of the rotation of the protective cover and to share part of the weight.
[0021] Furthermore, a ball valve is installed between the lower spray bar and the upper spray bar to control the water flow from the lower spray bar and the upper spray bar;
[0022] The cleaning roller is connected to the drive motor via a bearing seat, and a cleaning brush is provided below the cleaning roller; an adjusting screw is provided at the bottom of the lifting frame, and the adjusting screw is used to adjust the elevation angle suitable for cleaning operations.
[0023] Compared with existing technologies, the beneficial effects of the device for integrating guardrail cleaning and garbage collection provided by this utility model are:
[0024] The trash cans are installed on sanitation vehicles and are primarily used to store trash collected during the cleaning process. The trash cans work in conjunction with other systems to ensure efficient trash collection.
[0025] The clean water tank and spray system work together to provide a mist of water during garbage collection, helping to clean roads and guardrails. The clean water tank provides the necessary water source for the spray system. The water mist not only cleans but also helps reduce dust from garbage.
[0026] The sweeping system uses mechanical brushes to sweep the garbage scattered on the road surface to the edge of the suction nozzle.
[0027] The suction system, consisting of nozzles, a fan, and suction pipes, works together to draw waste into the waste bin. The fan generates negative pressure to ensure that waste is efficiently sucked into the waste bin.
[0028] The guardrail cleaning device connects to the cleaning vehicle via a connecting frame and is mainly used for cleaning guardrails along the route. With an adjustable angle structure, the cleaning device can clean guardrails of different heights and angles.
[0029] The connecting frame secures the cleaning device to the vehicle and connects the cleaning rollers via a rotating arm. The cleaning rollers rotate via a drive motor to clean the guardrail. The rotating arm can be adjusted to accommodate different cleaning positions.
[0030] The sliding frame allows the cleaning device to move horizontally on a horizontal plane. Driven by a moving motor, rack and pinion, and motor gear mechanism, the sliding frame can move within a set groove. Limit switches and stops ensure precise control of the movement distance, preventing accidental collisions and positioning errors.
[0031] The swivel cylinder provides the guardrail cleaning device with the ability to rotate within the range of 0 to 180°, allowing the cleaning operation to be adjusted according to the needs.
[0032] With the help of the swivel cylinder, the cleaning device can efficiently cover the guardrails at different angles and positions.
[0033] The omnidirectional casters support and distribute some of the weight of the guardrail cleaning device while providing flexible directional control. Their height is adjustable, ensuring the cleaning device's height adapts to different cleaning operation needs.
[0034] The rotating arm is equipped with bearing housings and rotates via a rotating rod. The cleaning rollers rotate via a drive motor, performing the actual cleaning task during the cleaning operation.
[0035] During the cleaning process, the water spray system of the protective cover, lower spray bar, and upper spray bar ensures that the water can be sprayed directly onto the cleaning roller and the object being cleaned, increasing the cleaning effect and preventing water from splashing.
[0036] The ball valve is used to control the water flow between the lower and upper spray bars, ensuring precise control of the water flow.
[0037] The cleaning brush below the cleaning roller further assists in the cleaning work, improving cleaning efficiency by working in conjunction with the water flow.
[0038] Adjusting the lead screw allows the lifting frame to adjust the angle of the cleaning operation at different elevation angles, ensuring that it can flexibly meet cleaning needs under different working conditions. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0047] like Figure 1-4 The image shows a first embodiment of a device for integrating guardrail cleaning and garbage collection provided by this utility model. In this embodiment, it includes a garbage bin 1, a clean water tank and a water spraying system 2, a sweeping system 3, a suction system 4, and a guardrail cleaning device 5. The garbage bin 1 is installed on a cleaning vehicle and is used to store garbage. Sweeping systems 3 are respectively installed on both sides of the cleaning vehicle to sweep the garbage to the edge of the suction nozzle of the suction system 4. The suction system 4 is connected to the garbage bin 1 and is used to suck the garbage collected by the sweeping system 3 into the garbage bin 1. The guardrail cleaning device 5 is fixedly connected to the front end of the cleaning vehicle through a connecting frame 6 and is used to clean the guardrail. A clean water tank and a water spraying system 2 are installed on the top of the garbage bin 1 for spraying water mist.
[0048] In the above technical solution, the suction system 4 includes a nozzle, a fan, and a suction pipe. One end of the suction pipe is connected to the garbage bin 1, and the other end is connected to the nozzle. The fan is installed inside the suction pipe to generate negative pressure.
[0049] Furthermore, in the above technical solution, the connecting frame 6 is connected to the chassis of the cleaning vehicle by bolts. The end of the connecting frame 6 away from the cleaning vehicle is connected to the cleaning roller 10 via the rotating arm 9. A fixed seat 7 and a lifting frame 8 are provided between the connecting frame 6 and the rotating arm 9. The fixed seat 7 is connected to the connecting frame 6 via the hanging plate seat 33. One end of the lifting frame 8 is connected to the sliding frame 12, and the other end is connected to the rotating arm 9. The rotating arm 9 is connected to the cleaning roller 10. A drive motor 14 is provided at one end of the cleaning roller 10. The drive motor 14 is used to drive the cleaning roller 10 to rotate to achieve the cleaning operation.
[0050] Furthermore, in the above technical solution, the fixed seat 7 is connected to the sliding frame 12. The sliding frame 12 has two sets of slider assemblies 27 arranged inside the upper and lower parts respectively. The lower part is equipped with a moving motor 17, a rack 18 and a motor gear 19, which are used to move the sliding frame 12 left and right along the end face of the slide groove 28 when the moving motor 17 drives the motor gear 19 to rotate.
[0051] Limit switches 32 and limit blocks 29 are installed on both sides of the sliding frame 12 to provide double protection, prevent movement out of position, and ensure safe and reliable sliding distance and position.
[0052] Furthermore, in the above technical solution, the sliding frame 12 and the lifting frame 8 are connected by a swing cylinder 30, which, under hydraulic drive, enables the guardrail cleaning device 5 to rotate at any angle within 0 to 180°.
[0053] Limit blocks 34 are installed on both sides of the sliding frame 12 to protect against mechanical damage caused by malfunction of the swing cylinder 30.
[0054] Furthermore, in the above technical solution, a left tension spring 20, a right tension spring 35, and an adjusting rod 21 are respectively installed on both sides between the lifting frame 8 and the swing arm 9, which are used to achieve adaptive obstacle avoidance by tightening the spring tension.
[0055] During operation, when cleaning in the direction of the driver, if the driver deviates from the designated cleaning distance and the cleaning roller touches an obstacle, the pressure increases with the depth of contact. At this point, the left tension spring is stretched by the force of the obstacle, while the right tension spring contracts, achieving adaptive obstacle avoidance. When the driver returns to the center position, both the left and right tension springs reset, returning the vehicle to its normal operating range within the designated cleaning distance, preventing collision damage to the cleaning device. Conversely, when cleaning in the direction of the driver's side, the obstacle avoidance principle is reversed. If the driver deviates from the designated cleaning distance and the cleaning roller touches an obstacle, the right tension spring is stretched by the force of the obstacle, while the left tension spring contracts, achieving adaptive obstacle avoidance. When the driver returns to the center position, both the left and right tension springs reset, returning the vehicle to its normal operating range within the designated cleaning distance.
[0056] Furthermore, in the above technical solution, the lifting frame 8 is a parallel four-bar linkage mechanism, with a lifting cylinder 13 installed inside, which is used to extend when the cleaning vehicle needs to be moved or stop working to lift the guardrail cleaning device 5 to the designated position.
[0057] When the guardrail cleaning device 5 is working, the sliding frame 12 moves laterally to the designated position, the swing cylinder 30 rotates to the designated position, the lifting cylinder 13 retracts, and the lifting frame 8 lowers the guardrail cleaning device 5 to a suitable working position by its own weight.
[0058] Furthermore, in the above technical solution, the lower part of the lifting frame 8 is equipped with universal rollers 16, which are used to bear and share part of the weight of the guardrail cleaning device 5; the height of the universal rollers 16 is adjustable to ensure that the cleaning height or ground clearance of the guardrail cleaning device 5 is consistent and to guide the movement direction of the guardrail cleaning device 5.
[0059] Furthermore, in the above technical solution, a bearing seat 39 is installed on the rotating arm 9, and the rotating rod 38 is rotatably arranged around the bearing seat 39. The protective cover 15 is fixed on the rotating rod 38 and is used to spray water onto the cleaning roller 10 and the object being cleaned through the water spray nozzles 25 installed on the lower spray rod 23 and upper spray rod 24 on both sides of the protective cover 15 when the cleaning roller 10 is performing cleaning operations.
[0060] The cleaning roller 10 is equipped with a cloth brush 36. When the cleaning roller 10 rotates and cleans, the cloth brush 36 will throw out water, which is blocked by the protective cover 15 from spreading to the surrounding area.
[0061] The protective cover 15 is provided with an elastic positioning pin 31, which is used to fix the rotation angle of the protective cover 15; a support roller 37 is provided below the protective cover 15 to ensure the stability of the rotation of the protective cover 15 and to share part of the weight.
[0062] Furthermore, in the above technical solution, a ball valve 22 is installed between the lower spray bar 23 and the upper spray bar 24 to control the water flow from the lower spray bar 23 and the upper spray bar 24.
[0063] The cleaning roller 10 is connected to the drive motor 14 via the bearing seat 39, and a cleaning brush 11 is provided below the cleaning roller 10; an adjusting screw 26 is provided at the bottom of the lifting frame 8, which is used to adjust the elevation angle suitable for the cleaning operation.
[0064] When the object to be cleaned is relatively tall, the ball valve is open, and water flows out from both the upper and lower spray bars simultaneously, meeting the water flow requirements for cleaning. Conversely, when the object to be cleaned is relatively short, spraying water from both the upper and lower spray bars simultaneously would cause unnecessary waste. In this case, the ball valve can be closed, and only the lower spray bars on both sides will spray water, which satisfies the cleaning requirements while avoiding water waste.
[0065] During cleaning operations, when the vehicle with sweeping and suction functions is activated moves forward, the guardrail cleaning device operates. Due to the rotation of the sweeping rollers, the garbage and dust on the surface of the object being cleaned will be washed off. At this time, the rotating sweeping brush at the bottom can remove the washed-off garbage and the residual garbage at the base of the object being cleaned. With the help of the cleaning vehicle's sweeping, suction, and water spraying functions, the garbage generated during the cleaning process can be collected into the garbage bin in a timely manner, avoiding secondary pollution and repetitive work caused by garbage scattering, thus improving the efficiency and quality of the cleaning work.
[0066] Specifically, the principle of this invention is as follows: Before starting the cleaning work, it is necessary to check all components of the device, including the trash can, the clean water tank, the sweeping system, the suction system, and the guardrail cleaning device, to ensure that all components are working properly. The clean water tank is then filled with clean water to provide sufficient water for the spray system.
[0067] Start the vehicle and ensure a secure connection to the cleaning unit. Activate the sweeping system to begin rotating the mechanical brushes and sweep away litter. Activate the suction system, ensuring the fan is operating properly and the litter is effectively sucked into the garbage bin.
[0068] Based on the position and height of the guardrail, the angle of the cleaning device is adjusted using a swing cylinder to ensure the cleaning rollers can contact the parts of the guardrail that need cleaning. The drive motor of the cleaning rollers is turned on, and the rollers begin to rotate, wiping the guardrail surface. The position of the cleaning device is adjusted using a sliding frame and a moving system to ensure the cleaning operation covers the entire guardrail area. The water spray system is activated, ensuring water flow is sprayed onto the cleaning rollers and guardrail through the upper and lower spray bars, effectively aiding the cleaning operation. The intensity and spray range of the water flow are adjusted using ball valves to achieve the best cleaning effect. When the object to be cleaned is relatively high, the ball valve is open, and water flows from both the upper and lower spray bars simultaneously, meeting the water flow requirements for the cleaning height. Conversely, when the object is relatively low, simultaneous spraying from both the upper and lower spray bars would be wasteful. In this case, the ball valve can be closed, allowing water to flow only from the lower spray bars on both sides, satisfying the cleaning needs while avoiding water waste. A sweeping brush assists the cleaning rollers, ensuring that debris and dirt on the guardrail surface are thoroughly removed.
[0069] During cleaning, the brush system gathers the trash near the suction nozzle, and the suction system draws it into the trash can. Regularly check if the trash can is full and empty it as needed.
[0070] During cleaning operations, the cleaning direction is towards the driver. When the driver is operating the vehicle at a suitable cleaning distance, if the vehicle deviates during the cleaning process and the cleaning roller touches an obstacle, the pressure increases with the depth of contact. At this time, the left tension spring is stretched under the external force of the obstacle, while the right tension spring contracts, achieving adaptive obstacle avoidance adjustment. When the driver returns to the center position, both the left and right tension springs reset, and the vehicle is now within the normal operating range of the suitable cleaning distance, preventing collision damage to the cleaning device. Conversely, during normal cleaning operations, the cleaning direction is towards the auxiliary driver, and the obstacle avoidance principle is reversed. If the vehicle deviates during the cleaning process and the cleaning roller touches an obstacle, the right tension spring is stretched under the external force of the obstacle, while the left tension spring contracts, achieving adaptive obstacle avoidance adjustment. When the driver returns to the center position, both the left and right tension springs reset, and the vehicle is now within the normal operating range of the suitable cleaning distance.
