TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal construction, in particular to a municipal water-stable base layer road roller and a road rolling method. BACKGROUND

[0002] The water-stable layer (cement-stabilized gravel / sandy gravel base layer) is the core load-bearing layer in the road structure, located above the roadbed and below the surface layer (such as the asphalt surface layer or the cement concrete surface layer), which forms a high-strength, stable and strong structural layer through the cementing effect of cement and the skeleton effect of aggregate, to provide solid support for the road surface.

[0003] In the prior art, for the construction of the water-stable base layer, the first step is to preset the center line and the side line of the road to be constructed, and install the elevation reference line. The second step is to clean the road surface and sprinkle water on the road to be constructed to maintain the moisture level of the road surface. The third step is to use a paver to pave. The fourth step is to use a road roller to compact the paving material. The fifth step is to cover the road surface with water for maintenance.

[0004] With regard to the related art described above, in the actual use process, for the construction of the water-stable layer of the small area road surface, the large equipment causes traffic congestion and high cost, and manual construction is low in efficiency and poor in effect. SUMMARY

[0005] In order to improve the construction efficiency of the water-stable layer of the small area road surface, the present application provides a municipal water-stable base layer road roller and a road rolling method.

[0006] The municipal water-stable base layer road roller provided by the present application adopts the following technical scheme: A municipal water-stable base layer road roller, comprising a vehicle body, a paving assembly and a spraying assembly; the vehicle body comprises a first vehicle body and a second vehicle body, the first vehicle body is rotatably connected to the second vehicle body, the bottom of the first vehicle body is rotatably connected with a first road roller, the bottom of the second vehicle body is rotatably connected with a second road roller, the first road roller and the second road roller are both in cylindrical shape, a first hydraulic pump is fixedly installed in the first vehicle body, the output end of the first hydraulic pump is connected to the first road roller, a second hydraulic pump is fixedly installed in the second vehicle body, the output end of the second hydraulic pump is connected to the second road roller; The paving assembly comprises a feeding hopper, a paving box and a switch assembly, the feeding hopper is fixedly connected to the top of the paving box, the paving box abuts against the ground, a connecting rod is rotatably connected to one side of the paving box, the other end of the connecting rod is rotatably connected to the second vehicle body, the switch assembly is arranged in the paving box, the paving box is divided into a feeding chamber and a heating chamber by a partition plate, a rectangular feeding opening is formed in the bottom of the feeding chamber, a paving piece is fixedly installed at the bottom of the paving box, the paving piece is arranged along the length direction of the rectangular feeding opening, the paving piece, the paving box and the ground are arranged in a triangular shape, and the paving assembly is used for paving the paving material. The spraying assembly is fixedly installed at the top of the first vehicle body, and is used for keeping the wetness of the road surface.

[0007] By adopting the above technical scheme, when the small-area water stable base is constructed, the spraying assembly is first opened, the driving device continuously sprays water on the road surface to be constructed to keep the road surface to be constructed wet. In the second step, the spraying assembly is closed, and the connecting rod drives the paving assembly to abut against the ground. The paving material from the feeding hopper flows out from the rectangular feeding opening and is paved and leveled by the paving box and the paving piece. In the third step, after the paving material is further cooled, the paving assembly is retracted through the connecting rod. At this time, the driving device repeatedly rolls the road surface by using the first road roller and the second road roller. In the fourth step, the spraying assembly is used to spray water on the paved road surface for maintenance. Therefore, the small-area water stable layer can be constructed without using large equipment. In addition, the road roller has multiple functions, including spraying, paving and rolling, so that the construction personnel can complete the construction of the small-area water stable layer alone, thereby improving the construction efficiency of the small-area water stable layer.

[0008] Optionally, the spraying assembly comprises a water storage tank, a booster pump and a spray head, the water storage tank is fixedly installed at the top of the first vehicle body, a water inlet is formed in the top of the water storage tank, the water inlet is communicated with the inside of the water storage tank, the booster pump is fixedly installed at the top of the water storage tank, the booster pump is connected to the spray head through a conveying pipeline, and a plurality of spray heads are arranged.

[0009] By adopting the above technical scheme, the sprayed water can be stored in the water storage tank in advance, and the road surface can be sprayed by the booster pump and the spray head to keep the wetness of the road surface, and the road surface can be maintained after the subsequent rolling is completed.

[0011] By adopting the above technical scheme, when the first and second hydraulic pumps drive the rolling shafts to rotate around the axes thereof, the rolling weights are also driven to rotate by the rolling shafts. The eccentricity between the rolling weights and the rolling shafts causes the rotating rolling weights to generate centrifugal force, so that greater rolling force can be provided when the road roller is used to roll the road surface.

[0012] Optionally, the first and second vehicle bodies are fixedly installed with coating and scraping members at the bottoms, and the coating and scraping members are obliquely arranged and respectively face the cylindrical surfaces of the first and second road rollers.

[0013] By adopting the above technical scheme, the coating and scraping members can scrape the paving materials attached to the cylindrical surfaces of the first and second road rollers during paving, so as to improve the rolling effect of the first and second road rollers.

[0014] Optionally, the first and second road rollers are hollow.

[0015] By adopting the above technical scheme, the hollow structure can not only reduce the weight of the road roller and the transportation cost of the road roller, but also adjust the rolling force of the road roller by arranging multiple rolling weights on the rolling shafts, so as to adapt to the rolling of road surfaces made of different materials.

[0016] Optionally, the paving box is rotationally connected with an auxiliary roller, and the auxiliary roller abuts against the ground together with the paving box.

[0017] By adopting the above technical scheme, the auxiliary roller can abut against the ground together with the paving box, so as to effectively reduce the friction between the paving box and the ground, thereby improving the durability of the paving box.

[0019] By adopting the technical scheme, if it is desired to stop paving, the discharging hydraulic cylinder can be opened to push the switch cover, so that the switch cover can pass from the switch hole into the discharging chamber from the heating chamber and block the discharging chamber. If it is desired to restart the paving assembly, the discharging hydraulic cylinder can be controlled to control the switch cover to retract from the discharging chamber back into the heating chamber, so that the discharging chamber continues to communicate with the discharging hopper, and the equipment starts to work again.

[0020] Optionally, the heating chamber bottom is fixedly connected with a heating plate, and the heating plate is attached to the heating chamber bottom.

[0021] By adopting the technical scheme, the heating plate can heat the paving box through heat conduction. If the paving material is asphalt material, the heated paving box can provide heat for the asphalt material to ensure that the temperature is uniform, so that problems such as "clumping" and "segregation" (separation of coarse and fine aggregates) do not occur, thereby ensuring the compactness and strength of the road surface.

[0022] Optionally, the second vehicle body top is provided with a driver's seat, and the second vehicle body top is fixedly provided with a control panel, which controls the opening and closing of the road roller, the paving assembly and the spraying assembly.

DETAILED DESCRIPTION

[0039] The following will be described in detail below with reference to the accompanying drawings. Figures 1-12 The present application is further described in detail.

[0040] Example 1 The embodiments of the present application disclose a municipal water stable base road roller. Referring to Figure 1 , the municipal water stable base road roller comprises a vehicle body 1, a paving assembly 3 and a spraying assembly 2.

[0041] Referring to Figure 2 , the vehicle body 1 comprises a first vehicle body 11 and a second vehicle body 12, and the first vehicle body 11 is rotationally connected to the second vehicle body 12. The first vehicle body 11 is rotationally connected with a first road roller 111 at the bottom. The second vehicle body 12 is rotationally connected with a second road roller 121 at the bottom, and the first road roller 111 and the second road roller 121 are both in a cylindrical shape. The cylindrical design not only helps the road roller to better roll the water stable base, but also assists the movement of the rolling equipment.

[0042] Referring to Figure 3 , the first road roller 111 and the second road roller 121 are both rotationally connected with a rolling shaft 13, and the two rolling shafts 13 are respectively arranged in the first road roller 111 and the second road roller 121. The two rolling shafts 13 are respectively provided with a hydraulic motor 14 at both ends. The first vehicle body 11 is fixedly installed with a first hydraulic pump 112 inside, the output end of the first hydraulic pump 112 is connected to the two hydraulic motors 14 of the first vehicle body 11, and then connected to the first road roller 111 through the hydraulic motor 14. The second vehicle body 12 is fixedly installed with a second hydraulic pump 122 inside, the output end of the second hydraulic pump 122 is connected to the two hydraulic motors 14 of the second vehicle body 12, and the rolling shaft 13 is provided with power through the hydraulic motor 14, and the rotation of the road roller is driven.

[0043] Referring toFigure 4 The middle part of the rolling rotation shaft 13 is fixedly installed with a rolling weight 15, and the two rolling rotation shafts 13 rotate coaxially with the first road roller 111 and the second road roller 121 respectively. There is an eccentricity between the rolling weight 15 and the rolling rotation shaft 13, so that when the rolling rotation shaft 13 rotates, the rolling weight 15 will also be driven to rotate by the rolling rotation shaft 13. Because of the eccentricity, the rolling weight 15 will generate centrifugal force when rotating, and the centrifugal force enables the two road rollers to exert greater rolling pressure on the water stable base layer pavement when the road roller equipment is used to roll the pavement, effectively improving the rolling effect.

[0044] Referring to Figure 5 The bottom of the first vehicle body 11 and the bottom of the second vehicle body 12 are fixedly installed with a coating and scraping part 16, which is inclined and respectively faces the cylindrical surface of the first road roller 111 and the second road roller 121. The coating and scraping part 16 can scrape off the paving material attached to the cylindrical surface of the first road roller 111 and the second road roller 121 during paving, thereby improving the rolling effect of the first road roller 111 and the second road roller 121.

[0045] Referring to Figure 6 The spraying assembly 2 comprises a water storage tank 21, a booster pump 22 and a spraying head 23, and the water storage tank 21 is fixedly installed on the top of the first vehicle body 11. A water inlet 201 is formed on the top of the water storage tank 21, which is communicated with the inside of the water storage tank 21, and the spraying water can be injected into the inside of the water storage tank 21 through the water inlet 201. The booster pump 22 is fixedly installed on the top of the water storage tank 21, and the spraying head is provided with a plurality of spraying heads, and the booster pump 22 is connected to each spraying head 23 through a delivery pipeline 24. The booster pump 22 can extract the spraying water in the water storage tank 21 and release it through the spraying head 23. The plurality of spraying heads 23 are arranged on the top of the first vehicle body 11 and the top of the paving tank 32, and the spraying heads 23 on the top of the first vehicle body 11 and the top of the paving tank 32 are arranged side by side. The side-by-side arrangement enables the spraying heads 23 at both ends to spray more densely during work, improving the spraying efficiency and quality. Before paving the water stable base layer, the road surface needs to be kept wet, the spraying water is stored in the water storage tank 21 in advance, and the road surface is watered through the booster pump 22 and the spraying head 23, so as to keep the road surface wet and maintain the road surface after the subsequent rolling.

[0046] Referring to Figure 7 and Figure 8The paving assembly 3 comprises a feeding hopper 31, a paving box 32 and a switch assembly 33, the feeding hopper 31 is fixedly connected to the top of the paving box 32. The paving box 32 is rotatably connected with two connecting rods 34 at one side, the other end of the two connecting rods 34 is rotatably connected to the second vehicle body 12, and a damping is arranged between the connecting rod 34 and the paving box 32 and between the connecting rod 34 and the second vehicle body 12, so that the connecting rod 34 and the paving box 32 are not easy to rotate at will. The paving box 32 is divided into a feeding chamber 301 and a heating chamber 302 by a partition plate 35. The bottom of the feeding chamber 301 is provided with a rectangular feeding port 303, the feeding chamber 301 is communicated with the feeding hopper 31, the paving material enters the feeding chamber 301 from the feeding hopper 31 and flows out from the rectangular feeding port 303. The bottom of the paving box 32 is fixedly installed with a paving piece 36, the paving piece 36 is arranged along the length direction of the rectangular feeding port 303, and the paving piece 36, the paving box 32 and the ground are triangularly arranged. The paving box 32 is rotatably connected with an auxiliary roller 37. The auxiliary roller 37 abuts against the ground together with the paving box 32. When the paving assembly 3 works, the auxiliary roller 37 can abut against the ground together with the paving box 32, the auxiliary roller 37 can effectively reduce the friction between the paving box 32 and the ground, thereby improving the durability of the paving box 32. The bottom of the heating chamber 302 is fixedly connected with a heating plate 38, and the heating plate 38 is attached to the bottom of the heating chamber 302. If the paving material is asphalt material, the heated paving box 32 can provide heat for the asphalt material, ensure the uniform temperature, so that it will not produce "clumping" and "segregation" (separation of coarse and fine aggregate) and other problems, thereby ensuring the compactness and strength of the road surface.

[0047] Referring to Figure 9 and Figure 10The switch assembly 33 comprises a switch cover 331 and a discharging hydraulic cylinder 332. The bottom of the heating chamber 302 is fixedly connected with a rotating rod 333, and one end of the switch cover 331 is rotatably connected to the rotating rod 333. One end of the discharging hydraulic cylinder 332 is rotatably connected to the switch cover 331, and the other end of the discharging hydraulic cylinder 332 is rotatably connected to the bottom of the heating chamber 302. The blocking plate 35 is provided with a switch hole 304. The sidewall of the discharging chamber 301 is provided with a blocking groove 305, which is matched with the front end of the switch cover 331. When the switch assembly 33 is in an open state, the switch cover 331 penetrates the switch hole 304 and abuts against the blocking groove 305. When the switch assembly 33 is in a closed state, the switch cover 331 is retracted into the discharging chamber 301. When it is necessary to stop the working of the paving assembly 3, the discharging hydraulic cylinder 332 can be opened to push the switch cover 331, so that the switch cover 331 penetrates from the switch hole 304 of the heating chamber 302 into the discharging chamber 301 and blocks the discharging chamber 301. If it is desired to reopen the paving assembly 3, the discharging hydraulic cylinder 332 can be controlled again to change from an extended state to a retracted state, and the switch cover 331 is retracted from the discharging chamber 301 back to the heating chamber 302. In this state, the discharging chamber 301 continues to communicate with the discharging funnel 31, and the equipment starts to work again.

[0048] Referring to Figure 11 The top of the second vehicle body 12 is provided with a driver's seat 123, and the top of the second vehicle body 12 is fixedly provided with a control panel 124. The first hydraulic pump 112, the second hydraulic pump 122, the booster pump 22, the discharging hydraulic cylinder 332 and the heating plate 38 are all provided with electronic elements (not shown in the figure) in electrical connection with the control panel 124, and the control panel 124 can control the opening and closing of the road roller, the paving assembly 3 and the spraying assembly 2. The top of the second vehicle body 12 is provided with a direction turning disc 125, which can control the turning of the first vehicle body 11 through a steering mechanism (not shown in the figure), so as to control the turning of the whole vehicle body 1, so that the worker can sit on the driver's seat 123 and control the working state of the road roller, the paving assembly 3 and the spraying assembly 2 through the control panel 124. And the turning of the vehicle body 1 is controlled through the direction turning disc 125. Through the above scheme, integrated control and work can be realized, so as to improve the construction efficiency of the small-area road water stable layer.

[0049] The implementation principle of the municipal water-stable base road-rolling equipment of the embodiment 1 is as follows: according to the construction sequence of the water-stable layer, the operator can sit on the driver seat 123 and control the operation of the equipment through the control panel 124. When the spraying assembly 2 needs to spray water, the control panel 124 sends an electric signal to the booster pump 22, and the booster pump 22 receives the electric signal to extract the spraying water from the water storage tank 21 and then deliver the spraying water to the spraying head 23 through the delivery pipeline 24. When the paving assembly 3 needs to work, the paving material enters from the material outlet and flows out from the rectangular material outlet 303, and the flowed-out paving material is heated by the paving box 32 and then paved by the paving piece 36 and the paving box 32.

[0050] When the paving assembly 3 needs to stop working, the control panel 124 sends an electric signal to the material discharging hydraulic cylinder 332, the material discharging hydraulic cylinder 332 pushes the switch from the switch hole 304 to enter the heating chamber 302 into the material discharging chamber 301, and blocks the material discharging chamber 301 so that the paving assembly 3 stops working. When the first road roller 111 and the second road roller 121 need to work, the control panel 124 controls the first hydraulic pump 112 and the second hydraulic pump 122 to work, the first hydraulic pump 112 and the second hydraulic pump 122 transmit mechanical energy to the hydraulic motor 14, the hydraulic motor 14 outputs energy to the rolling shaft 13, the rolling shaft 13 rotates and drives the rolling weight 15 to rotate, and the rolling weight 15 generates centrifugal force when rotating, which can exert greater rolling force on the water-stable base road surface and effectively improve the rolling effect.

[0051] Embodiment 2 The embodiment 2 of the present application discloses a municipal water-stable base road-rolling method, which is implemented by the municipal water-stable base road-rolling equipment of the embodiment 1 and comprises the following technical features. Referring to Figure 12 For the construction of a small-area water-stable base, a large paving machine, a water spraying vehicle and a road roller are not needed. A municipal water-stable base road-rolling equipment can be independently controlled by a worker and the construction can be performed through the following steps.

[0052] The first step is to preset a path, enclose the to-be-constructed area, and install a height reference line, and then the road-rolling equipment walks along the preset path.

[0053] The second step is to spray and moisten, turn on the spraying assembly 2, and drive the equipment to continuously spray water on the to-be-constructed road surface to keep the to-be-constructed road surface moist.

[0054] The third step is to pave the road surface, turn off the spraying assembly 2, and drive the connecting rod 34 to abut the paving assembly 3 to the ground, the paving material entering from the material hopper 31 flows out from the rectangular material outlet 303 and is paved and leveled by the paving box 32 and the paving piece 36.

[0055] The fourth step is repeated rolling, and after the paving material is further cooled, the driving device is driven to repeatedly roll the road surface by the first roller 111 and the second roller 121.

[0056] The fifth step is spraying maintenance, and the paving material is sprayed and maintained by the spraying assembly 2. After seven days, the small-area water-stable layer is completed.
