Description

TECHNICAL FIELD

[0001] The utility model relates to the field of highway maintenance pavement cleaning, specifically to a highway maintenance pavement cleaning device. BACKGROUND

[0002] With the continuous expansion of the highway network and the growth of the service life, the maintenance work of its pavement and surrounding facilities becomes increasingly important and faces many challenges.

[0003] On the highway, various iron parts such as screws, nuts, metal fragments, etc. often fall off during vehicle driving. These iron parts scattered on the road not only affect the neatness of the road, but more seriously, they can cause damage to the tires of subsequent vehicles, leading to tire burst and other safety accidents, and also may interfere with the normal operation of traffic facilities. The traditional road cleaning method often relies on manual cleaning or simple magnetic tools for iron part cleaning. Manual cleaning is inefficient and it is difficult to ensure that the iron parts are completely cleaned. Ordinary magnetic tools lack flexibility and automation, making it difficult to meet the rapid and efficient maintenance needs of highways. Moreover, after absorbing the iron parts, they lack effective storage and transfer mechanisms, which can easily cause the iron parts to fall back onto the road.

[0004] On the other hand, the side fences of highways are exposed to the natural environment for a long time, accumulating a large amount of dust, dirt, and sticky substances attached by vehicle exhaust. These pollutants not only affect the aesthetics of the fence, but also accelerate the corrosion and damage of the fence, reducing its protective function and service life. The existing fence cleaning methods are mostly manual with simple tools for scrubbing. This method is labor-intensive, inefficient, and difficult to ensure consistency and thoroughness of cleaning effect. For some higher positions or hard-to-reach fence parts, manual cleaning poses a safety hazard, and there is a lack of effective devices for simultaneous washing during the cleaning process, which cannot timely remove the dirt cleaned. In addition, the existing mechanical operation method for cleaning the fence is to use a mechanical arm to support a roller to complete the cleaning, but there is a lot of water mist during washing, and the water mist is not controlled. Moreover, the spray head is set in front of the roller for washing, and the washing result is not good.

[0005] In addition, the highway pavement itself also needs to be cleaned regularly due to pollutants such as dust, dirt, and oil stains brought by vehicle driving. Conventional road cleaning equipment has relatively single function, either only having blowing function and being unable to completely remove stubborn stains, or only being able to perform simple washing and having poor cleaning effect on some dry and tightly attached pollutants. The existing road cleaning cannot flexibly combine blowing and washing according to the needs.

[0006] In summary, in order to improve the maintenance efficiency and quality of the highway pavement and the surrounding facilities, and to ensure the safety, beauty and long-term stable operation of the highway, a new type of highway maintenance pavement cleaning device capable of efficiently, automatically, multifunctionally and flexibly switching the cleaning mode for the pavement ironwork, the side fence and the pavement itself is urgently needed.

[0025] The following is the implementation process of the highway maintenance road cleaning device described in the present application:

[0026] I. Assembly of the device: Construct the vehicle body 1 for carrying various functional components. The vehicle body 1 should have sufficient strength and stability to adapt to the highway driving environment and the installation and operation requirements of various components. The design of the vehicle body should consider factors such as center of gravity distribution, power system layout, and space reservation for each functional module, to ensure that there are no problems such as unstable center of gravity and component interference during subsequent installation and operation. Fix the electromagnet horizontal control cylinder 6 horizontally at the designated position at the front end of the vehicle body 1, ensuring that it is securely installed and meets the requirements for levelness, so that the telescopic end can stably drive the bracket 4 to move horizontally. Connect the bracket 4 with the telescopic end of the electromagnet horizontal control cylinder 6, and the connection method should ensure the strength and reliability of the connection, while leaving some space for movement, so that the bracket 4 can move smoothly horizontally under the action of the cylinder.

Finally, fix the iron piece storage basket 7 at the lower front end of the vehicle body 1, ensuring that its position is accurate and compatible with the movement path of the electromagnet body 3, so that it can smoothly receive the adsorbed and transferred iron pieces.

[0027] Install the telescopic arm 9 at the appropriate position at the front end of the vehicle body 1. The connection between the telescopic arm 9 and the vehicle body 1 should have sufficient strength and stability, and the telescopic action should be flexible and smooth without jamming or interference. Connect the fence cleaning device 8 through the telescopic arm 9, so that the fence cleaning device 8 can be lifted as a whole under the action of the telescopic arm 9. After the connection is completed, check the reliability of the connection part to ensure that it will not loosen or fall off during operation of the device.

[0028] Install the cleaning roller A12 and the cleaning roller B13 in the shell 10 of the fence cleaning device 8, so that their shafts can rotate smoothly, and install rotating gears A14 on the shafts respectively. Install the motor 11 on the shell 10, and connect the rotating end of the motor 11 with the rotating gear B15, ensuring that the motor 11 can accurately drive the two sets of rotating gears A14 through the rotating gear B15, so that the cleaning roller A12 and the cleaning roller B13 can rotate stably.

[0029] Install three groups of fence washing nozzles 16 vertically on the side of the shell 10, corresponding to the front, middle, and rear parts of the shell 10 respectively, ensuring that the nozzles are securely installed and that the spray direction and angle of the nozzles can meet the washing needs of different stages of cleaning, while ensuring that the shell 10 can effectively prevent the expansion of washing water vapor, and the sealing performance of the shell 10 can be tested and adjusted.

[0030] The blowing pipe 2 is installed at the rear end of the vehicle body 1, vertically installed and sealed well at the high-pressure fan connection part on the vehicle body 1, to ensure that the airflow generated by the high-pressure fan can smoothly enter the blowing pipe 2. During connection, sealing glue, flange connection and other methods can be used to ensure the sealing and stability of the connection to prevent airflow leakage.

At the same time, the road surface washing nozzle 17 is connected with the water tank and water pump in the vehicle body through the pipeline, to ensure that the pipeline connection is tight and leak-free, and necessary valves, filters and other components are installed on the pipeline to control the washing water flow and filter impurities in the water, and to protect the water pump and the nozzle.

[0031] II. Device debugging phase: start the electromagnet unit, check whether the electromagnet body 3 can normally generate a magnetic field, and whether the magnetic field strength meets the design requirements. A magnetic field strength tester can be used for detection, and if the magnetic field strength is insufficient, the coil turns, current size and other parameters of the electromagnet body 3 can be checked and adjusted.

[0032] Test the action of the electromagnet height-lifting cylinder 5 and the electromagnet horizontal control cylinder 6 respectively, and observe whether the electromagnet body 3 moves up and down and horizontally under the action of the cylinder smoothly and accurately. Different cylinder stroke and speed parameters are set through the controller to check whether the electromagnet body 3 can accurately reach the specified position according to the set requirements, and if there are problems such as jamming and deviation, the sealing of the cylinder, the lubrication of the guide rail and the normality of the signal transmission of the control system can be checked, and corresponding adjustment and repair can be made. Perform iron piece adsorption test, place some iron pieces in the simulated road surface environment, start the device to make the electromagnet body 3 descend to adsorb the iron pieces, and then move the adsorbed iron pieces to the iron piece storage basket 7 through the cylinder action, check whether the whole adsorption and transfer process is smooth, and whether the iron pieces can be stably stored in the basket, and if the iron pieces fall off, the adsorption force of the electromagnet body 3, the action speed and force of the cylinder and the structure design of the iron piece storage basket 7 can be adjusted.

[0033] Start the motor 11, check if the cleaning drum A 12 and the cleaning drum B 13 can rotate normally, and whether the rotating speed is stable and meets the design requirements. The rotating speed can be measured by using a tachometer. If the rotating speed is abnormal, the power supply of the motor 11, the meshing condition of the transmission gear, and the lubrication condition of the bearing of the drum can be checked, and corresponding adjustment and maintenance can be performed. The lifting and lowering functions of the telescopic arm 9 are tested, and whether the overall movement of the fence cleaning device 8 under the action of the telescopic arm 9 is smooth and flexible is observed. The telescoping stroke of the telescopic arm 9 is checked to see whether it meets the height range requirement of fence cleaning. If there are problems such as unsmooth movement or insufficient stroke, the working condition of the hydraulic system (if it is hydraulically driven) or the electric drive system of the telescopic arm 9 can be checked, including the oil pump pressure, motor power, and cooperation condition of the guide rail slider, and adjustment and optimization can be performed. Turn on the water pump of the fence washing nozzle 16, check the water spraying condition of the nozzle, including whether the water spraying pressure, water spraying angle, and water spraying volume meet the design requirements. Pressure gauges, flowmeters, and other tools can be used for detection. If the water spraying effect is not ideal, the performance of the water pump, the clogging condition of the nozzle, and the pressure loss of the pipeline can be checked, and cleaning, maintenance, or adjustment of the pipeline layout can be performed.

[0034] Start the high-pressure fan, check the air outlet condition of the blowing pipe 2, and use an anemometer to measure the air speed at the outlet of the blowing pipe 2 to ensure that the air speed meets the design requirements and can effectively blow away the road surface pollutants. If the air speed is insufficient, the speed of the high-pressure fan, the angle of the fan blades, and the internal resistance of the blowing pipe 2 can be checked, and corresponding adjustments can be made, such as adjusting the fan speed and cleaning the inside of the blowing pipe 2.

[0035] III. Device operation

[0036] Preparation before operation: Before starting the device, the operator should conduct a comprehensive inspection of the equipment, including whether the connection of each part is firm, whether the running state of each power system (such as motor, cylinder, high-pressure fan, water pump, etc.) is normal, whether each functional part (such as electromagnet body 3, cleaning drum A 12 and B 13, fence washing nozzle 16, road surface washing nozzle 17, etc.) is in the initial position and has no damage or clogging phenomenon, etc. At the same time, it is ensured that the fuel (if it is fuel-driven) or electricity (if it is electrically driven) of the vehicle body 1 is sufficient, and there is enough water in the water tank for washing operation.

[0037] Road surface iron cleaning operation: Start the device, make the vehicle body 1 run at a constant speed on the highway, according to the road surface condition and the distribution of iron parts, control the action of the electromagnetic iron height lifting cylinder 5 and the electromagnetic iron horizontal control cylinder 6 through the controller, make the electromagnetic iron body 3 descend to the appropriate height and approach the road surface to adsorb the iron parts on the road surface. During the adsorption process, the running speed of the vehicle body 1 can be adjusted according to the actual situation to ensure that the electromagnetic iron body 3 has enough time to adsorb the iron parts. When the electromagnetic iron body 3 adsorbs the iron parts, the adsorbed iron parts are transferred to the iron parts storage basket 7 through the action of the cylinder, completing the cleaning and storage operation of the iron parts. During the whole process, the operator should pay close attention to the working state of the electromagnetic iron unit, such as the decrease of adsorption force, the falling of iron parts and other abnormal conditions, and should stop the vehicle for inspection and treatment in time.

[0038] Fence cleaning operation: When the vehicle body 1 runs to the road section where the fence needs to be cleaned, the fence cleaning device 8 is lifted to the appropriate height through the telescopic arm 9, so that the cleaning roller A12 and the cleaning roller B13 can contact the surface of the fence. Start the motor 11 to make the cleaning roller A12 and the cleaning roller B13 rotate, and at the same time, start the water pump of the fence washing nozzle 16 to wash and clean the fence in the order of before, middle and after.

[0039] During the cleaning process, the speed of the motor 11, the pressure of the water pump and the running speed of the vehicle body 1 can be adjusted according to the pollution degree and material characteristics of the fence to achieve the best cleaning effect. The operator should pay attention to the observation of the brush wear of the cleaning roller and the water spray of the fence washing nozzle, such as the serious wear of the brush or the blockage of the nozzle, and should replace the brush or clean the nozzle in time.

[0040] Road surface blowing and washing operation: When cleaning the road surface, select the blowing or washing operation mode according to the pollution condition of the road surface. If the road surface is mainly contaminated by dust, light debris and other pollutants, start the high-pressure blower to blow and clean the road surface through the blowing pipe 2. During the blowing process, the angle and height of the blowing pipe 2 can be adjusted to make the blowing air flow cover the entire road surface width to improve the blowing effect. If the road surface has oil stains, stubborn stains and other pollutants that are difficult to remove by blowing, install the road surface washing nozzle 17 and start the water pump to wash and clean the road surface. During the washing process, the angle and height of the road surface washing nozzle 17, as well as the pressure and flow of the water pump can be adjusted to ensure the washing effect. At the same time, the operator should pay attention to the observation of the road surface drainage to prevent water accumulation from affecting traffic.

[0041] Job process monitoring and adjustment: During the whole device operation process, the operator should monitor the working state and job effect of each part in real time through various sensors and monitoring equipment (such as magnetic field intensity sensor, rotating speed sensor, pressure sensor, camera, etc.). For example, the magnetic field intensity change of electromagnet body 3 is monitored through the magnetic field intensity sensor, and the fault of electromagnet unit is found in time; the fence cleaning device 8 and the road surface cleaning effect are observed through the camera, so as to adjust the job parameters in time. According to the monitoring result, if it is found that a certain functional part works abnormally or the cleaning effect is poor, the vehicle should be stopped in time for inspection and adjustment. For example, if it is found that the air outlet wind speed of blowing pipe 2 decreases, it may be that the high-pressure fan is faulty or the blowing pipe 2 is blocked inside, so the fan and blowing pipe should be checked and corresponding maintenance should be carried out; if it is found that the fence is not cleaned thoroughly, the rotating speed of the cleaning roller, the hardness of the brush, or the water pressure of the flushing nozzle can be adjusted to improve the cleaning effect.
