Description

Technical Field

[0001] This invention relates to the field of road construction, and in particular to a construction device and process for asphalt pavement structures for municipal roads. Background Technology

[0002] Asphalt pavement is a road surface formed by fully mixing asphalt mixture and then spreading and compacting it. During use, asphalt pavement can not only withstand the repeated loads of vehicles, but also has good durability, anti-aging and crack resistance, etc., and its performance is very stable.

[0003] Nowadays, special paving equipment is usually used to spread asphalt mixture during the paving process. However, uneven spreading can sometimes occur during the operation of the special paving equipment, resulting in local depressions in the asphalt pavement. In addition, local damage and depressions may also occur during the long-term use of asphalt pavement. For the depressions on the asphalt pavement, workers usually need to shovel up some asphalt mixture to fill and level the depressions one by one, which makes the repair work of asphalt pavement quite inconvenient. Summary of the Invention

[0004] To facilitate the repair of depressions in asphalt pavements, this application provides a construction device and process for asphalt pavement structures used in municipal roads.

[0005] In the first aspect, the technical solution of the construction device for asphalt pavement structure of municipal roads provided in this application is as follows:

[0006] A construction device for asphalt pavement structure of municipal roads includes a base plate, a material supply bucket fixedly connected to the base plate, and casters that are rolled on the base plate. A partition plate is fixed inside the material supply bucket, and asphalt mixture is located above the partition plate. A material discharge hole is opened on the upper part of the partition plate. A sealing plate that can block the material discharge hole is slidably arranged on the bottom surface of the partition plate. A filling hole is opened on the base plate, and a rotating blade for paving asphalt mixture is rotatably arranged in the filling hole. A pulling mechanism for pulling the sealing plate away from the material discharge hole is provided on the partition plate. A resetting mechanism for pushing the sealing plate back to its original position is also provided on the partition plate. A detection mechanism for detecting road surface potholes is provided on the base plate. The detection mechanism is used to control the operation of the pulling mechanism.

[0007] By adopting the above technical solution, when the testing agency detects a pothole on the asphalt pavement, the testing agency can control the pulling mechanism to pull the sealing plate, causing the sealing plate to slide away from the discharge hole. At this time, the upper and lower sides of the material box are connected through the discharge hole, allowing the asphalt mixture to fall from the discharge hole to below the partition plate. As the workers push the construction device, when the filling hole is above the pothole, the asphalt mixture falling below the partition plate can fill the pothole through the filling hole and the rotating blades set in the filling hole. This eliminates the need for workers to shovel up the asphalt mixture to fill and level the pothole in turn, thus facilitating the repair of potholes on the asphalt pavement.

[0008] Preferably, a baffle is fixedly connected to the partition plate, and the tension mechanism includes an attraction block fixedly connected to the sealing plate. An electromagnet that can generate an attraction force on the attraction block is fixedly connected to the side of the baffle near the sealing plate.

[0009] By adopting the above technical solution, when the electromagnet's electrical circuit is turned on, the electromagnet can attract the attraction block, causing the attraction block to slide the sealing plate closer to the electromagnet. This allows the asphalt mixture above the partition plate to fall into the space below the partition plate. As the workers push the construction device, when the filling hole is above the depression, the asphalt mixture can pass through the filling hole and fill and flatten the depression under the rotation of the rotating blades.

[0010] Preferably, the detection mechanism includes a fixed tube fixedly mounted on the base plate, a detection rod slidably mounted inside the fixed tube, a roller at the bottom end of the detection rod, a first spring for applying a pushing force to the detection rod inside the fixed tube, a fixed contact plate embedded in the inner wall of the fixed tube, a movable contact plate embedded in the side of the detection rod that can contact the fixed contact plate, a power supply fixedly connected to the base plate, the movable contact plate being electrically connected to one end of the coil in the electromagnet, the other end of the coil in the electromagnet being electrically connected to one electrode of the power supply, and the other electrode of the power supply being electrically connected to the fixed contact plate.

[0011] By adopting the above technical solution, when the roller reaches the depression, the detection rod slides downward, causing the moving contact to contact the fixed contact, thus opening the electromagnet's electrical circuit. At this time, the electromagnet attracts the attraction block, causing the attraction block to drive the sealing plate to slide away from the discharge hole, allowing the asphalt mixture to fall into the space below the partition plate. The rotating blades then fill the depression in the road surface. After the roller passes through the depression area and rolls to the flat road surface, the detection rod slides into the fixed tube, causing the moving contact to disengage from the fixed contact. This allows the sealing plate to re-seal the discharge hole under the action of the reset mechanism, enabling the construction device to drop an appropriate amount of asphalt mixture according to the length of the depression.

[0012] Preferably, a pressure roller is rotatably mounted on the bottom of the base plate, and a first motor is fixed on the base plate to drive the pressure roller to rotate.

[0013] By adopting the above technical solution, the first motor drives the pressure roller to rotate, so that the pressure roller can press and roll the asphalt mixture filled into the depression, making the filled asphalt mixture harder and flatter.

[0014] Preferably, the base plate has an adjustment hole and an adjustment mechanism. The adjustment mechanism includes an adjustment rod passing through the adjustment hole and slidably mounted on the base plate. A caster wheel is fixed to the bottom end of the adjustment rod. An adjustment nut is rotatably mounted on the top surface of the base plate and threadedly connected to the adjustment rod. A limiting component is provided between the adjustment rod and the inner wall of the adjustment hole to prevent relative rotation between the adjustment rod and the base plate.

[0015] By adopting the above technical solution, after the filling work is completed, the power is turned off. Due to the threaded connection between the adjusting nut and the adjusting rod, the adjusting nut is rotated, and the adjusting rod can slide vertically relative to the base plate under the restriction of the limiting component. This allows the workers to lift the pressure roller off the ground, thus making the workers more free and convenient to move the construction device.

[0016] Preferably, an annular groove is formed on the top surface of the base plate, and an annular limiting groove is formed on the inner circumferential surface of the annular groove. A connecting ring is fixedly connected to the bottom surface of the adjusting nut, and a limiting ring is fixedly connected to the connecting ring. The connecting ring is rotatably disposed in the annular groove, and the limiting ring is rotatably disposed in the annular limiting groove.

[0017] By adopting the above technical solution, the connecting ring is rotatably set in the annular groove, and the limiting ring is rotatably set in the annular limiting groove. This allows the adjusting nut to rotate on the base plate while preventing it from detaching from the base plate, thus enabling the adjusting nut to rotate more stably on the base plate. At the same time, the rotatable setting of the connecting ring and the limiting ring in the annular limiting groove increases the rotational resistance of the adjusting nut, thereby reducing the possibility of the adjusting rod sliding vertically due to the rotation of the adjusting nut during the pushing of the construction device.

[0018] Preferably, the adjusting hole has a strip groove on its wall, and the limiting component includes a limiting block fixedly connected to the adjusting rod, the limiting block being slidably disposed in the strip groove.

[0019] By adopting the above technical solution, the limiting block is fixedly connected to the adjusting rod, and the limiting block is slidably set in the strip groove, thereby preventing the adjusting rod from detaching from the base plate, so that the adjusting rod can slide more stably on the base plate.

[0020] Preferably, the reset mechanism includes a second spring disposed between the stop bar and the sealing plate, one end of the second spring being fixedly connected to the stop bar, and the other end of the second spring being fixedly connected to the sealing plate.

[0021] By adopting the above technical solution, when the tensioning mechanism loses its tension on the sealing plate, under the opposing action of the second spring, the sealing plate can slide towards the discharge hole, so that the sealing plate blocks the discharge hole and prevents the asphalt mixture from continuing to fall below the separator plate.

[0022] Preferably, guide blocks are symmetrically arranged on both sides of the sealing plate, the guide blocks are fixedly connected to the partition plate, and guide grooves are opened on the guide blocks. The two sides of the sealing plate are respectively slidably arranged in the two guide grooves.

[0023] By adopting the above technical solution, the guide block is fixedly connected to the partition plate, the guide groove is opened on the guide block, and the two sides of the sealing plate are slidably set in the guide grooves on the two guide blocks, so that the sealing plate can slide more stably on the partition plate.

[0024] Secondly, this application provides a construction process for an asphalt pavement structure for municipal roads, which adopts the following technical solution:

[0025] A construction process for an asphalt pavement structure for municipal roads includes the following steps: S1: Transfer the construction device to the asphalt pavement, fill the spacer plate of the material supply bucket with asphalt mixture, and at this time the power supply is off; S2: Adjust the height of the base plate by adjusting the adjusting nut so that the pressure roller abuts against the ground, start the first motor, at this time the moving contact plate disengages from the fixed contact plate and is located above the fixed contact plate, and turn on the power supply; S3: Push the construction device so that the roller passes over the depressions on the asphalt pavement.

[0026] By adopting the above technical solution, when the construction device pushes the roller over the depression on the asphalt pavement, the first spring pushes the detection rod downward to slide, so that the moving contact plate contacts the fixed contact plate, thereby turning on the electromagnet's electrical circuit. At this time, the electromagnet attracts the attraction block, which causes the attraction block to drive the sealing plate to slide away from the discharge hole. The asphalt mixture can fall into the space below the partition plate and fill the depression on the road surface through the rotating blades. At the same time, after the roller passes through the depression area and rolls to the flat road surface, the detection rod slides into the fixed tube, so that the moving contact plate disengages from the fixed contact plate. Thus, the sealing plate re-seals the discharge hole under the action of the reset mechanism, thereby enabling the construction device to drop an appropriate amount of asphalt mixture according to the length of the depression.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the testing agency detects a pothole on the asphalt pavement, the worker pushes the construction device. The testing agency can control the pulling mechanism to pull the sealing plate, causing the sealing plate to slide away from the discharge hole. At this time, the upper and lower sides of the material box are connected through the discharge hole, allowing the asphalt mixture to fall from the discharge hole to below the partition plate. As the worker pushes the construction device, when the filling hole is above the pothole, the asphalt mixture falling below the partition plate can fill the pothole through the filling hole and the rotating blades set in the filling hole. This eliminates the need for the worker to shovel up the asphalt mixture to fill and level the pothole in turn, making it easier for the worker to repair the potholes on the asphalt pavement.

[0029] 2. When the electromagnet's electrical circuit is activated, the electromagnet can attract the attraction block, causing the attraction block to slide the sealing plate closer to the electromagnet. This allows the asphalt mixture above the partition plate to fall into the space below the partition plate. As the workers push the construction device, when the filling hole is above the depression, the asphalt mixture can pass through the filling hole and fill and flatten the depression under the rotation of the rotating blades.

[0030] 3. Push the construction device. When the roller reaches the depression, the detection rod slides downward, causing the moving contact to contact the fixed contact. This activates the electromagnet's electrical circuit, attracting the attraction block. The attraction block then drives the sealing plate to slide away from the discharge hole, allowing the asphalt mixture to fall into the space below the partition plate. The rotating blades then fill the depression in the road surface. After the roller passes through the depression and rolls to a flat surface, the detection rod slides into the fixed tube, causing the moving contact to disengage from the fixed contact. This allows the sealing plate to reseal the discharge hole under the action of the reset mechanism, enabling the construction device to drop an appropriate amount of asphalt mixture according to the length of the depression.

When the detection rod 73 passes through the depression on the ground, the detection rod... 73 slides downward inside the fixed tube 72, causing the movable contact piece 76 to contact the fixed contact piece 77, thereby turning on the electrical circuit of the electromagnet 51. At this time, the asphalt mixture can fall from the discharge hole 411 to below the partition plate. The asphalt mixture falling below the partition plate 41 can fill the depression through the filling hole 17 and the rotating blade 191 rotatably set in the filling hole 17, so that the workers do not need to shovel the asphalt mixture to fill and level the depression in turn, thus making it easier for the workers to repair the depressions of the asphalt pavement.
