Description

Technical Field

[0002] Preventive road maintenance, also known as preventive maintenance, is a method of implementing planned maintenance measures when the pavement's structural strength is sufficient and the pavement is in good condition. Its primary purpose is to maintain or improve the pavement's performance, extend its service life, and reduce periodic maintenance costs. To enhance the pavement's skid resistance and wear resistance and reduce the incidence of pavement defects, construction workers inject emulsified asphalt into the pre-treatment device. During the movement of the device, the emulsified asphalt is sprayed onto the road surface. Emulsified asphalt is waterproof, dustproof, adhesive, and easy to apply. Once laid on the pavement, it forms an ultra-thin curing layer, enhancing the pavement's skid resistance and wear resistance and reducing the incidence of pavement defects. Before spraying the emulsified asphalt, pneumatic equipment is used to blow away dust and impurities from the road surface to prevent them from interfering with the direct contact and adhesion between the emulsified asphalt and the pavement.

[0028] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1:

[0030] Refer to the instruction manual Figures 1 to 8 A road pre-maintenance device includes a driving vehicle 1, a spraying mechanism 2 is provided on the driving vehicle 1, the spraying mechanism 2 includes a storage tank 21, the storage tank 21 is fixedly provided on the driving vehicle 1, a conveyor 22 is fixedly provided on the driving vehicle 1, the extraction end of the conveyor 22 extends into the storage tank 21, the storage tank 21 is connected with a conveying pipe 23, the discharge end of the conveying pipe 23 is fixedly connected with a connecting pipe 25, and the bottom end of the connecting pipe 25 is fixedly provided with a nozzle; a dust removal mechanism 3 is provided on the driving vehicle 1, and a dust removal mechanism 3 is provided on the driving vehicle 1. The structure 3 includes a storage box 31, which is fixedly mounted on the driving vehicle 1. An air pump 34 is arranged in the storage box 31. The suction end of the air pump 34 extends to the bottom of the storage box 31. A shielding net 36 is arranged in the storage box 31. A monitoring unit is fixedly mounted on the bottom of the driving vehicle 1. The monitoring unit includes a data acquisition module, a data analysis module and a communication module. The output end of the data acquisition unit is connected to the input end of the data analysis module, and the output end of the data analysis module is connected to the input end of the communication module.

[0031] It should be noted that conveyor 1 22 is configured as an asphalt pump, the extraction end of the asphalt pump being fixedly connected to the storage tank 21, and the discharge end of the asphalt pump being fixedly connected to the delivery pipe 23. A stirring rod is rotatably disposed within the storage tank 21, and is used to stir the material within the storage tank 21. The stirring rod is driven by a motor. Auxiliary rollers are rotatably disposed at the bottom of the driving vehicle 1, and these rollers first brush the road surface, thereby attracting and collecting dust particles and impurities on the road surface.

[0032] The specific implementation scenario is as follows: first, the emulsified asphalt is loaded into the diversion tank 41, and then the driving vehicle 1 is driven to move to the designated position. During construction, the driving vehicle 1 is driven to move and the conveyor 22 and the vacuum pump 34 are started. The vacuum pump 34 sucks the dust and particulate impurities on the road surface into the storage box 31 to collect the dust and particulate impurities on the road surface. Compared with the method of blowing the road dust away from the road surface by blowing, the blowing will cause the dust to float in the air, causing air pollution and having a negative impact on the safety of the workers. The conveyor 22 conveys the emulsified asphalt in the storage tank 21 to the connecting pipe 25 through the conveying pipe 23. Finally, the emulsified asphalt is sprayed on the road surface through the nozzle, and a maintenance layer is formed between the emulsified asphalt and the road surface. Because the dust and particulate impurities on the road surface are removed, the contact area between the emulsified asphalt and the road surface is increased, thereby improving the use effect of the maintenance layer.

[0033] Refer to the instruction manual Figures 1 to 5 In order to further improve the transportation efficiency of emulsified asphalt, specifically, the driving vehicle 1 includes a conveyor 24, which is fixedly arranged on the driving vehicle 1, the conveying pipe 23 is fixedly connected to the extraction end of the conveyor 24, and the connecting pipe 25 is fixedly connected to the discharge end of the conveyor 24.

[0034] It should be noted that the second conveyor 24 is configured as an asphalt pump, the extraction end of the asphalt pump is fixedly connected to the delivery pipe 23, and the discharge end of the asphalt pump is fixedly connected to the connecting pipe 25. The surfaces of the delivery pipe 23 and the connecting pipe 25 are both provided with an insulation layer to keep the emulsified asphalt warm.

[0035] It should also be noted that during the construction process, the second conveyor 24 is started. The second conveyor 24 can improve the circulation efficiency of the emulsified asphalt and prevent the length of the conveying pipe 23 and the connecting pipe 25 from affecting the conveying efficiency of the emulsified asphalt.

[0036] Refer to the instruction manual Figures 1 to 5 In order to facilitate the collection of dust and impurity particles on the road and to carry out centralized and unified treatment, specifically, the dust removal mechanism 3 includes a support plate, which is fixedly arranged on the inner wall of the storage box 31, and a collection frame 33 is slidably arranged on the support plate. The collection frame 33 is provided with an air vent, and a suction nozzle cover 32 is fixedly arranged on the suction end of the air exhauster 34, and the exhaust end of the air exhauster 34 is connected to the air vent.

[0037] It should be noted that an inclined plate is fixedly provided on the inner wall of the collection frame 33, and the inclined plate is located above the air vent. Impurities in the gas entering the collection frame 33 through the air vent fall into the collection frame 33, and the inclined plate can prevent impurities from leaking out through the air vent.

[0038] It should also be noted that when the vacuum pump 34 is started, the vacuum pump 34 attracts impurities on the road surface, and the impurities accumulate in the collection frame 33. After the device has been used for a period of time, the collection frame 33 is taken out and the impurities in the collection frame 33 are cleaned.

[0039] Refer to the instruction manual Figure 5 The dust and impurity particles on the road surface are collected by the vacuum pump 34. The dust often contains flocculent impurities. During long-term use, the flocculent impurities will accumulate on the surface of the shielding net 36. In order to prevent the accumulation of impurities on the surface of the shielding net 36 from affecting the discharge of clean gas in the storage box 31, specifically, the storage box 31 is fixedly connected to an exhaust pipe 35, and a fixed shaft is rotatably set in the exhaust pipe 35. The shielding net 36 is fixedly set on the fixed shaft, and the shielding net 36 is in contact with the inner wall of the exhaust pipe 35.

[0040] It should be noted that a sprocket is fixedly provided on the fixed shaft, a motor is fixedly provided on the storage box 31, a sprocket is fixedly provided on the output shaft of the motor, multiple sprockets are connected to the same chain for transmission, and the rotation of the motor output shaft drives the shielding net 36 to rotate.

[0041] It should also be noted that the vacuum pump 34 draws external air into the storage box 31, and the air passes through the shielding net 36 from bottom to top and is discharged from the storage box 31, causing flocculent dust and impurities to easily accumulate at the bottom of the shielding net 36. When maintaining this device, the motor is started, and the rotation of the motor output shaft drives the sprocket to rotate, and the sprocket transmission chain rotates multiple fixed shafts, and the rotation of the fixed shaft drives the shielding net 36 to rotate. When the shielding net 36 is flipped over, the flocculent dust and impurities are on the surface of the shielding net 36. At this time, the staff can clean up the accumulated impurities, and during use, the gas is still discharged from the shielding net 36 from bottom to top, which can blow away the dust tightly adsorbed on the surface of the shielding net 36, thereby achieving the effect of clearing the mesh of the shielding net 36.

[0042] Refer to the instruction manual Figures 1 to 4 In order to improve the utilization rate of the device, make the device have more functions, prevent each device from having only one function, avoid wasting equipment resources, and increase unnecessary usage costs, specifically, a grouting mechanism 4 is provided on the driving vehicle 1, and the grouting mechanism 4 includes a diversion tank 41, which is fixedly arranged on the driving vehicle 1, and a conveyor three 42 is fixedly arranged on the driving vehicle 1, and the extraction end of the conveyor three 42 extends into the diversion tank 41, and the discharge end of the conveyor three 42 is fixedly connected to a discharge pipe 43.

[0043] It should be noted that conveyor 3 42 is configured as an asphalt pump, the extraction end of the asphalt pump extending into the diversion tank 41, and the discharge end of the asphalt pump fixedly connected to the discharge pipe 43. An auxiliary pipe is fixedly connected to the diversion tank 41, and the end of the auxiliary pipe away from the diversion tank 41 is fixedly connected to the delivery pipe 23. Gate valves are fixedly installed on both the delivery pipe 23 and the auxiliary pipe. When it is necessary to lay an emulsified asphalt layer on the road surface, the gate valve on the auxiliary pipe is closed, and a passage is formed between the storage tank 21, the delivery pipe 23, and the connecting pipe 25, achieving the effect of spraying and laying the emulsified asphalt layer. When it is necessary to repair cracks on the road surface for the purpose of local grouting, the gate valve on the delivery pipe 23 is closed and the gate valve on the auxiliary pipe is opened, forming a passage between the storage tank 21, the diversion tank 41, and the discharge pipe 43. The emulsified asphalt in the storage tank 21 is sprayed out through the discharge pipe 43, and the handheld workpiece required for grouting is connected to the discharge pipe 43.

[0044] It should also be noted that a monitoring unit is fixedly installed at the bottom of the driving vehicle 1. The monitoring unit can assist construction workers in filling small cracks in the road surface, determine the location of small cracks for construction workers, and improve construction efficiency. The monitoring unit includes a data acquisition module, a data analysis module, and a communication module. The output end of the data acquisition unit is connected to the input end of the data analysis module, and the output end of the data analysis module is connected to the input end of the communication module. The data acquisition module is configured as a monitoring camera and a temperature and humidity sensor. The monitoring camera records road conditions, and the temperature and humidity sensor detects the temperature and humidity of the road surface. The data analysis module is configured as a PLC controller. The data analysis module receives and analyzes the data acquired by the data acquisition module. The data analysis module transmits the obtained road condition information, temperature and humidity, and other information to the communication module. The output end of the communication module is connected to the input end of the mobile terminal. The communication module is used to transmit the results obtained by the data analysis module. A display screen is fixedly installed on the driving vehicle 1. The output end of the communication module is connected to the input end of the display screen. The display screen is used to display the data transmitted by the communication module, and construction workers can view the relevant data on the display screen. A power supply module is fixedly provided on the driving vehicle 1 , and the power supply module is configured as a battery, and the power supply module supplies power to other components.

[0045] During the movement of the driving vehicle 1, the data acquisition module collects information on the road surface gaps, temperature and humidity, and the collected results will be displayed on the display screen. When encountering cracks on the road, there are two ways of construction. One way is that the driving vehicle 1 moves on the road, and the data acquisition module analyzes the road surface information passed by the driving vehicle 1, and then the construction personnel fill the gaps. This method is conducive to the construction of small gaps; the other way is that the staff fills the gaps on the road surface visually. This method is suitable for filling larger gaps. After the staff completes the filling of the gaps on the road surface, the driving vehicle 1 is pushed through the filled gaps, and the data acquisition module analyzes the road surface conditions again to ensure that the road surface gaps are completely filled with caulking glue.

[0046] Example 2:

[0047] Refer to the instruction manual Figure 6 In spring, there are many flocculent impurities such as poplar and willow catkins on the road surface. When the present device is used for road maintenance, many flocculent impurities on the road surface are extracted by the vacuum pump 34. In order to automatically clean the flocculent impurities accumulated on the shielding net 36 and ensure that the clean air in the storage box 31 can be discharged efficiently, the storage box 31 is specifically provided with an anti-blocking mechanism, which includes a cleaning component 51. The cleaning component 51 includes a linear drive 511. The linear drive 511 is fixedly arranged in the storage box 31. A scraper 1 is fixedly arranged on the output shaft of the linear drive 511. The scraper 1 is in contact with the shielding net 36. A rotary drive 513 is fixedly arranged on the storage box 31. A cover plate 512 is fixedly arranged on the output shaft of the rotary drive 513. The cover plate 512 is in contact with the top of the exhaust pipe 35.

[0048] It should be noted that linear actuator 1 511 is configured as a cylinder fixedly mounted within storage box 31, scraper 1 is fixedly mounted on the cylinder's output shaft, and rotary actuator 1 513 is configured as a motor, the motor's output shaft being fixedly mounted to cover plate 512. Three motors are mounted on storage box 31, and their output shafts are fixedly mounted to a fixed shaft, meaning that each shielding net 36 is independently controlled by a motor's output shaft.

[0049] It should also be noted that when cleaning the flocculent impurities accumulated on the shielding net 36, the rotary driver 513 is first started, and the rotation of the output shaft of the rotary driver 513 drives the cover plate 512 to cover the exhaust pipe 35, so that the gas will not be discharged from the covered exhaust pipe 35, and then the linear driver 511 is started, and the movement of the output shaft of the linear driver 511 drives the scraper plate to move. The movement of the scraper plate cleans the flocculent impurities at the bottom of the shielding net 36 and dredges the mesh of the shielding net 36. Since some flocculent impurities are entangled with each other and are not easily scraped off by the scraper plate, the scraper plate scrapes away the impurities on the shielding net 36, so that the output shaft of the motor drives the shielding net 36 to rotate to realize the flipping of the shielding net 36, and then the cover plate 512 is reset, and the impurities on the surfaces of multiple shielding nets 36 are cleaned in turn. The gas is still discharged from the shielding net 36 from bottom to top, which can blow away the dust tightly adsorbed on the surface of the shielding net 36, thereby achieving the effect of dredging the mesh of the shielding net 36.

[0050] Example 3:

[0051] Refer to the instruction manual Figure 7 and Figure 8 , which is different from the above-mentioned method of using multiple motors to block the top of the exhaust pipe 35, when blocking the exhaust pipe 35 to clean the dust on the shielding net 36, in order to reduce the use of the driving source and reduce the production cost of the equipment, the anti-blocking mechanism includes a cleaning component 2 52, and the cleaning component 2 52 includes a top plate 521, and the top plate 521 is in contact with the top of the exhaust pipe 35. A rotating driver 2 523 is fixedly provided in the storage box 31, and the top plate 521 is fixedly provided on the output shaft of the rotating driver 2 523. The output shaft of the rotating driver 2 523 is also fixedly provided with a connecting seat 524, and a semi-arc bevel gear 525 is fixedly provided on the connecting seat 524. A transmission bevel gear 526 is fixedly provided on the fixed shaft, and the semi-arc bevel gear 525 is meshed with the transmission bevel gear 526. A scraper 2 522 is fixedly provided on the connecting seat 524, and the scraper 2 522 is adapted to the shielding net 36.

[0052] It should be noted that the rotating driver 2 523 is configured as a motor, a connecting shaft is fixedly provided on the output shaft of the motor, the top plate 521 and the connecting seat 524 are both fixedly provided on the connecting shaft, and the exhaust pipes 35 are arranged in sequence along the axis of the output shaft of the rotating driver 2 523, that is, the distance from each exhaust pipe 35 to the axis of the output shaft of the rotating driver 2 523 is the same, and the connecting lines of multiple exhaust pipes 35 form a circle.

[0053] It should also be noted that the top plate 521 is configured as an arc-shaped plate, that is, after the top plate 521 contacts the exhaust pipe 35 , even if the top plate 521 continues to rotate, the top plate 521 still blocks the corresponding exhaust pipe 35 .

[0054] In this embodiment, the rotation driver 2 523 is started, and the rotation of the output shaft of the rotation driver 2 523 drives the top plate 521 to rotate synchronously with the connecting seat 524. When the top plate 521 contacts the top of the exhaust pipe 35 and completely blocks the top of the exhaust pipe 35, the exhaust pipe 35 is closed, and then the connecting seat 524 drives the scraper 2 522 to clean the dust at the bottom of the shielding net 36. When the scraper 2 522 finishes cleaning the dust at the bottom of the shielding net 36, with the continuous rotation of the connecting seat 524, the semi-arc bevel gear 525 engages with the transmission bevel gear 526, and the transmission bevel gear 526 drives the shielding net 36 to flip 180° in the exhaust pipe 35. The gas is still discharged from the shielding net 36 from bottom to top, which can blow away the dust tightly adsorbed on the surface of the shielding net 36, thereby achieving the effect of clearing the mesh of the shielding net 36. In this way, the dust on multiple shielding nets 36 can be cleaned.

[0055] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
