Description

Technical Field

[0001] The utility model belongs to the technical field of road maintenance, and particularly relates to a road compaction and maintenance device. Background Technique

[0002] Road compaction and maintenance devices play a crucial role in road construction. Especially in the compaction operation, they ensure the stability and durability of the road. When the road surface is damaged, one of the commonly used repair materials is asphalt because it has good adhesion and durability, and can effectively restore the flatness and bearing capacity of the road surface. After asphalt repair, the next key step is to use a compaction device to compact the asphalt. The purpose of this step is to ensure that the newly laid asphalt is tightly combined with the original road surface, eliminate voids, and improve the density and flatness of the road surface.

[0003] However, when the existing road compaction and maintenance devices are in use, their pressing rollers can only compact the road surface with a specific width. This means that when dealing with a wider road surface, the device needs to operate back and forth multiple times to cover the entire road surface area, which undoubtedly increases the operation time and labor costs. If some larger compaction devices are directly used, it will be difficult to move on some narrower road surfaces. Content of the Utility Model

[0004] The utility model provides a road compaction and maintenance device, aiming to solve the problem that the existing road compaction and maintenance devices consume more operation time and labor costs when compacting a wider road surface as proposed in the above background technique.

[0005] To solve the above problems, the utility model is realized as follows. A road compaction and maintenance device includes: a support plate, one end of the bottom of the support plate is fixedly installed with a first bracket, and a large pressing roller is rotatably installed on the first bracket; two second brackets arranged side by side in the center of the bottom of the support plate, and small pressing rollers are rotatably installed on both of the second brackets; a housing fixedly installed in the center of the bottom of the support plate; a spacing adjustment mechanism installed on the housing for adjusting the spacing between the two small pressing rollers; a jacking mechanism assembled on the support plate for lifting the two small pressing rollers; and a cleaning mechanism arranged on the support plate for cleaning impurities.

[0006] Preferably, the jacking mechanism includes: a hydraulic cylinder fixedly installed at the other end of the bottom of the support plate, an installation frame fixedly installed on the output rod of the hydraulic cylinder; and a roller rotatably installed on the installation frame.

[0007] Preferably, the spacing adjustment mechanism includes: a bidirectional screw rod rotatably installed on the housing along the axial direction, two sliders are threadedly installed on two threaded sections of the bidirectional screw rod, and the bottoms of the two sliders are respectively fixedly connected to the two second brackets; a servo motor fixedly installed on one side of the housing, the output shaft of the servo motor is fixedly connected to one end of the bidirectional screw rod; a slide rod fixedly installed on the housing, and the slide rod is slidably connected to the two sliders.

[0008] Preferably, the cleaning mechanism includes: a box body fixedly installed on the top of the support plate, a rotating shaft is vertically rotatably installed in the box body, and a plurality of stirring rods are fixedly installed on the rotating shaft; a driving motor fixedly installed on the top of the box body, the output shaft of the driving motor is fixedly connected to the top end of the rotating shaft; a high-pressure water pump fixedly installed on the top of the support plate, a water suction pipe is fixedly installed on the water suction end of the high-pressure water pump, and one end of the water suction pipe extends into the interior of the box body; a discharge pipe fixedly installed on the water discharge end of the high-pressure water pump, and one end of the discharge pipe extends below the support plate; a shunt pipe fixedly installed on the discharge pipe, and a plurality of nozzles are arranged on the shunt pipe.

[0009] Preferably, a positioning plate is fixedly installed at the bottom of the support plate, and the bottom of the positioning plate is fixedly connected to the shunt pipe.

[0010] Preferably, a water adding pipe is fixedly installed on the top of the box body, and a sealing cover is arranged on the water adding pipe.

[0011] Preferably, two counterweights are fixedly installed on the top of the support plate, and a handrail is fixedly installed on one side of the support plate.

[0012] Compared with the related art, the pavement compaction and maintenance equipment provided by the present utility model has the following beneficial effects:

[0013] The two small rollers can then be lowered to allow the user to move the two small rollers away from the ground, so that the user can adjust the distance between the two small rollers. After the adjustment is completed, the two small rollers can be lowered by the lifting mechanism, and then the road surface compaction and maintenance equipment can be pushed to move on the ground, so that the large roller compacts the repair position of the road surface, and the edge position that has not been compacted by the large roller will be compacted by the two small rollers. In this way, the entire road surface area can be covered without multiple round trips, thereby reducing the operation time and labor costs, and the use effect is better. When the distance between the two small rollers is adjusted to the minimum by the distance adjustment mechanism, the overall width of the equipment can be reduced, so that the equipment can also be moved on some narrower roads. The cleaning mechanism can use high-pressure water to wash impurities on the large roller and the two small rollers. To improve the washing effect, the large roller and the two small rollers need to roll back and forth on the ground, which is more convenient to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides a road surface compaction and maintenance device, such as Figures 1-4 shown, the road surface compaction and maintenance device includes: a support plate 1, a first bracket 2 is fixedly installed at one end of the bottom of the support plate 1, a large compaction roller 3 is rotatably installed on the first bracket 2; two second brackets 4 arranged side by side in the center of the bottom of the support plate 1, small compaction rollers 5 are rotatably installed on both of the second brackets 4; a housing 6 fixedly installed in the center of the bottom of the support plate 1; a spacing adjustment mechanism installed on the housing 6 for adjusting the spacing between the two small compaction rollers 5; a jacking mechanism assembled on the support plate 1 for lifting the two small compaction rollers 5; a cleaning mechanism arranged on the support plate 1 for cleaning impurities.

[0022] In this embodiment, when using this device to compact the road surface, if the width of the repaired road surface is greater than that of the large roller 3, the spacing adjustment mechanism needs to be used. Before adjustment, the lifting mechanism is required to lift the support plate 1 so that the two small rollers 5 can be lifted. Then, the spacing adjustment mechanism can be used to drive the two second brackets 4 away from each other. The two second brackets 4 will drive the two small rollers 5 away from each other, so that the running tracks of the two small rollers do not coincide with the running track of the large roller. After the spacing between the two small rollers 5 is adjusted, the lifting mechanism is used to lower the two small rollers 5. Then, this road surface compaction and maintenance equipment can be pushed to move on the ground, so that the large roller 3 compacts the repaired position of the road surface, and the edge positions not compacted by the large roller 3 will be compacted by the two small rollers 5. In this way, the entire road surface area can be covered without multiple round trips, thereby reducing the operation time and labor costs, and the use effect is better. When this equipment travels on some narrow road surfaces, the user can also use the spacing adjustment mechanism to drive the two small rollers 5 closer to each other, so as to reduce the overall width of this equipment and enable this equipment to move on some narrow road surfaces. After the road surface compaction work is completed, during the process of moving this equipment, if it is necessary to wash the impurities on the large roller 3 and the two small rollers 5, the cleaning mechanism can be used to spray high-pressure water on the large roller 3 and the two small rollers 5 to wash down the impurities adhered to the surfaces of the large roller 3 and the two small rollers 5, and the cleaning is relatively convenient.

[0023] In a further preferred embodiment of the present invention, the lifting mechanism includes: a hydraulic cylinder 11 fixedly installed at the other end of the bottom of the support plate 1, and an installation frame fixedly installed on the output rod of the hydraulic cylinder 11; a roller 12 rotatably installed on the installation frame.

[0024] In this embodiment, the lifting mechanism is used to lift the two small rollers 5. When in use, the hydraulic cylinder 11 is started, and the hydraulic cylinder 11 will drive the installation frame to move vertically. The installation frame will drive the roller 12 to move vertically. When the roller 12 contacts the ground and the hydraulic cylinder 11 still continues to work, the hydraulic cylinder 11 will support the support plate 1 so that the two small rollers 5 can be lifted. After the two small rollers 5 are lifted, it is convenient to use the spacing adjustment mechanism to adjust the spacing between the two small rollers 5.

[0025] In a further preferred embodiment of the present invention, the spacing adjustment mechanism includes: a bidirectional screw 7 rotatably installed on the housing 6 along the axial direction, two sliders 8 are threadedly installed on the two threaded sections of the bidirectional screw 7, and the bottoms of the two sliders 8 are respectively fixedly connected to the two second brackets 4; a servo motor 9 fixedly installed on one side of the housing 6, and the output shaft of the servo motor 9 is fixedly connected to one end of the bidirectional screw 7; a slide bar 10 fixedly installed on the housing 6, and the slide bar 10 is slidably connected to the two sliders 8.

[0026] In this embodiment, the spacing adjustment mechanism is used to adjust the two small pressure rollers 5. When adjusting, the servo motor 9 is started. The servo motor 9 drives the bidirectional screw 7 to rotate. The bidirectional screw 7 drives the two sliders 8 to slide horizontally on the slide rod 10. The two sliders 8 drive the two second brackets 4 to approach or move away from each other, thereby realizing the adjustment of the spacing between the two small pressure rollers 5, and the adjustment is relatively convenient.

[0027] In a further preferred embodiment of the present utility model, the cleaning mechanism includes: a box body 13 fixedly installed on the top of the support plate 1. A rotating shaft 14 is vertically rotatably installed in the box body 13, and a plurality of stirring rods are fixedly installed on the rotating shaft 14; a driving motor 15 fixedly installed on the top of the box body 13, and the output shaft of the driving motor 15 is fixedly connected to the top end of the rotating shaft 14; a high-pressure water pump 16 fixedly installed on the top of the support plate 1. A water suction pipe is fixedly installed on the water suction end of the high-pressure water pump 16, and one end of the water suction pipe extends into the interior of the box body 13; a discharge pipe 17 fixedly installed on the water discharge end of the high-pressure water pump 16, and one end of the discharge pipe 17 extends below the support plate 1; a shunt pipe 18 fixedly installed on the discharge pipe 17, and a plurality of nozzles 19 are provided on the shunt pipe 18.

[0028] In this embodiment, the cleaning mechanism is used to clean impurities. When in use, first inject clean water into the box body 13. If some substances that help clean impurities need to be added to the box body 13, the driving motor 15 needs to be started. The driving motor 15 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the plurality of stirring rods to rotate, uniformly mixing the added substances into the clean water. After mixing is completed, the high-pressure water pump 16 is started. The high-pressure water pump 16 transports the water in the box body 13 to the shunt pipe 18 through the water suction pipe and the discharge pipe 17, and finally sprays out from the plurality of nozzles 19. The sprayed high-pressure water is sprayed on the large pressure roller 3 and the two small pressure rollers 5. If the large pressure roller 3 and the two small pressure rollers 5 are rolling at this time, the impurities on the large pressure roller 3 and the two small pressure rollers 5 can be effectively flushed, and the impurities adhered to the surfaces of the large pressure roller 3 and the two small pressure rollers 5 are flushed off, and the cleaning is relatively convenient.

[0029] In a further preferred embodiment of the present utility model, a positioning plate 20 is fixedly installed at the bottom of the support plate 1, and the bottom of the positioning plate 20 is fixedly connected to the shunt pipe 18.

[0030] In this embodiment, through the use of the positioning plate 20, a good supporting effect can be achieved on the shunt pipe 18, so that the shunt pipe 18 can maintain good stability during use.

[0031] In a further preferred embodiment of the present utility model, a water adding pipe is fixedly installed on the top of the box body 13, and a sealing cover is provided on the water adding pipe.

[0032] In this embodiment, through the water adding pipe, it is convenient for the user to add the required clean water or substances into the box body 13, and through the sealing cover, the water adding pipe can be blocked to prevent foreign impurities from entering the box body 13 through the water adding pipe.

[0033] In a further preferred embodiment of the present utility model, two counterweight blocks are fixedly installed on the top of the support plate 1, and a handrail is fixedly installed on one side of the support plate 1.

[0034] In this embodiment, through the use of the two counterweight blocks, the overall weight of the device can be increased, thereby improving the stability of the device during the compaction operation. Through the handrail, it is convenient for the user to push the device.

[0035] In summary, compared with the related art, through the use of the jacking mechanism in this solution, it is convenient to lift the two small pressing rollers 5, so that the two small pressing rollers 5 are separated from the ground. In this way, it is convenient for the user to use the spacing adjustment mechanism to adjust the spacing between the two small pressing rollers 5. After the adjustment is completed, the two small pressing rollers 5 are lowered by using the jacking mechanism. Then, the road compaction and maintenance device can be pushed to move on the ground, so that the large pressing roller 3 compacts the repaired position of the road surface, and the edge position that is not compacted by the large pressing roller 3 will be compacted by the two small pressing rollers 5. In this way, the entire road surface area can be covered without multiple round trips, thereby reducing the operation time and labor cost, and the use effect is better. When the spacing between the two small pressing rollers 5 is adjusted to the minimum by using the spacing adjustment mechanism, the overall width of the device can be reduced, so that the device can also move on some narrow road surfaces. Through the cleaning mechanism, high-pressure water can be used to wash the impurities on the large pressing roller 3 and the two small pressing rollers 5. If the washing effect needs to be improved, it is necessary to make the large pressing roller 3 and the two small pressing rollers 5 roll back and forth on the ground, and the cleaning is relatively convenient.

[0036] In several embodiments provided by the present application, it should be understood that the disclosed device can be implemented in other ways.
