Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a road paving device and its paving method. Background Technology

[0002] Asphalt used for road paving is usually obtained by vacuum distillation of crude oil of appropriate properties, or by vacuum residue oil after shallow oxidation or propane deasphalting process. It can also be made by blending asphalt of different ductility and penetration grades. Asphalt binder improves the ability of paving aggregates to resist damage to the road surface from traffic and natural factors, making the road surface smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used type of road surface in road paving.

[0008] Preferably, a rotating ring B is rotatably connected to the upper end of the rotating ring A, and a movable rod is vertically connected to the rotating ring B. The movable rod moves through the top of the chassis and is connected to a rectangular sliding frame. A mounting bracket A is fixed on the chassis, and a transmission mechanism is mounted on the mounting bracket A. The transmission mechanism includes a drive motor A, a gear belt A, and two gears A. The two gears A are rotatably mounted on the upper and lower ends of the mounting bracket A, respectively, and are connected to each other by the gear belt A. The drive motor A is mounted on the mounting bracket A, and its output shaft is connected to the rotating shaft of the gear A. A movable column is fixed on the gear belt A, and the movable column is movably disposed in the sliding hole of the rectangular sliding frame.

[0009] Preferably, the chassis is also provided with a mounting bracket B, and gears B are rotatably mounted on the upper and lower ends of the mounting bracket B. A gear belt B is connected between the two gears B. A transmission rod is connected between the gears B and the gears A at the corresponding height. A lifting block is fixed on the gear belt B. A pressure plate is provided on the side of the chassis away from the U-shaped frame A. A guide rod A is connected to the pressure plate. A fixing block is provided on the chassis.

[0014] On the other hand, the present invention also provides a method for laying the above-mentioned road paving device, comprising the following steps:

[0015] S1. Adjust the positions of the two pressure sensors according to the paving range of the road. Drive the two sliding plates to move closer or further apart through the set power component B. The sliding plates then move the pressure sensors. When the moving slider contacts the pressure sensor on either side, the power component B starts to drive the moving slider to change direction and move.

[0017] S3. During the movement of the slider, the ball and the mounting rod move. During the movement of the mounting rod, the lever can move the asphalt, so that the asphalt is spread evenly on the road surface. At the same time, the ball moves on the protrusion, so that the wedge repeatedly pushes the mounting rod to move. Under the elastic force of the elastic component, the mounting rod can be driven to move back and forth, thereby improving the asphalt moving effect.

[0018] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: The positions of the two pressure sensors are adjusted according to the paving range of the road. A power component B drives the two sliding plates to move closer or further apart. The movement of the sliding plates, in turn, drives the pressure sensors to move. When the moving slider contacts the pressure sensor on either side, the power component B starts to drive the moving slider to change direction, thereby achieving the limiting function of the feeding nozzle. A power component A drives the moving slider to move, thereby causing the feeding nozzle to reciprocate during the movement of the machine casing. The movement of the sliding block ensures the uniformity of material feeding. During its movement, the sliding block moves the ball and the mounting rod, which in turn moves the lever to agitate the asphalt, spreading it evenly on the road surface. Simultaneously, the ball moves on the protruding block, causing the wedge block to repeatedly push the mounting rod. Under the elastic force of the elastic component, the mounting rod can be driven to reciprocate. In summary, this invention, by setting a moving feeding nozzle and lever, and with the lever generating vibration during movement, enables the asphalt to be spread more evenly and smoothly on the road surface, thus ensuring the paving effect.

Detailed Implementation

[0023] Example 1

[0024] like Figures 1-4 As shown, the present invention proposes a road paving device, including a housing 1; a drive wheel 27 is installed at the bottom of the housing 1, a U-shaped frame A2 is provided on the side of the housing 1, a movable slider 3 is slidably installed on the inner side of the U-shaped frame A2, a power component A for driving the movable slider 3 is installed on the U-shaped frame A2, a fixed plate 38 is provided on the movable slider 3, a movable plate 37 is provided on one side of the fixed plate 38, an elastic component is connected between the movable plate 37 and the fixed plate 38, an installation rod 6 is fixedly connected to the movable plate 37, a plurality of levers 7 are arranged side by side on the installation rod 6, a through hole 301 is opened on the movable slider 3, a wedge block 35 is slidably installed on the inner side of the through hole 301, a ball 36 is connected to the end of the wedge block 35, a protrusion 10 is provided on the inner side of the U-shaped frame A2, a feeding nozzle 4 is installed at the bottom of the movable slider 3, and a feeding mechanism 5 is connected between the feeding nozzle 4 and the output end of the housing 1. Two slide plates 11 are symmetrically arranged on the inner side of the U-shaped frame A2. Pressure sensors 12 are arranged on the opposite sides of the two slide plates 11. A power component B is installed on the U-shaped frame A2 to drive the two slide plates 11 to move closer or further apart.

[0025] The power assembly A includes a servo motor A81, a threaded rod 82, and a slide rod A83. The slide rod A83 is fixed on the U-shaped frame A2. The movable slider 3 is slidably mounted on the slide rod A83. The threaded rod 82 is rotatably mounted on the U-shaped frame A2. The movable slider 3 is threadedly connected to the threaded rod 82. The servo motor A81 is mounted on the side of the U-shaped frame A2, and its output shaft is connected to the threaded rod 82.

[0026] The elastic component includes a guide rod B39, a spring 40, and a limiting block B41. The guide rod B39 is fixed on the fixed plate 38. One end of the guide rod B39 movably passes through the movable plate 37 and is connected to the limiting block B41. The spring 40 is sleeved and installed on the guide rod B39.

[0027] The power assembly B includes a servo motor B91, a bidirectional lead screw 92, and a slide bar B93. The slide bar B93 is fixed on the U-shaped frame A2. Both slide plates 11 are slidably mounted on the slide bar B93. The bidirectional lead screw 92 is rotatably mounted on the U-shaped frame A2. Both slide plates 11 are threadedly connected to the bidirectional lead screw 92. The servo motor B91 is mounted on the side of the U-shaped frame A2, and its output shaft is connected to the bidirectional lead screw 92.

[0028] In this embodiment, the positions of the two pressure sensors 12 are adjusted according to the paving range of the road. The power component B drives the two sliding plates 11 to move closer or further apart. The movement of the sliding plates 11 drives the pressure sensors 12 to move. When the moving slider 3 contacts the pressure sensor 12 on either side, the power component B starts to drive the moving slider 3 to change direction, thereby realizing the limiting work of the feeding nozzle 4. The power component A drives the moving slider 3 to move, thereby driving the feeding nozzle 4 to reciprocate during the movement of the machine box 1, so as to ensure the uniformity of the equipment feeding. During the movement of the moving slider 3, the ball 36 and the mounting rod 6 move. During the movement of the mounting rod 6, the lever 7 can move the asphalt, so that the asphalt is spread evenly on the road surface. At the same time, the ball 36 moves on the protrusion 10, so that the wedge block 35 repeatedly pushes the mounting rod 6 to move. Under the elastic force of the elastic component, the mounting rod 6 can be driven to move back and forth, so that the asphalt can be spread more evenly and evenly on the road surface.

[0029] Example 2

[0030] like Figures 1-3 As shown, the road paving device proposed in this invention, compared with Embodiment 1, further includes a cylindrical hole 101 provided on the housing 1. An installation shaft 31 is installed on the inner side of the cylindrical hole 101. A drive motor B30 for driving the installation shaft 31 to rotate is installed at the bottom of the housing 1. A rotating ring A32 is installed on the installation shaft 31. A plurality of stirring rods 33 are connected to the rotating ring A32.

[0031] A rotating ring B34 is rotatably connected to the upper end of a rotating ring A32. A movable rod 22 is vertically connected to the rotating ring B34. The movable rod 22 movably passes through the top of the chassis 1 and is connected to a rectangular sliding frame 20. A mounting bracket A13 is fixed on the chassis 1. A transmission mechanism is mounted on the mounting bracket A13. The transmission mechanism includes a drive motor A143, a gear belt A142, and two gears A141. The two gears A141 are rotatably mounted on the upper and lower ends of the mounting bracket A13, respectively. The two gears A141 are connected by a gear belt A142. The drive motor A143 is mounted on the mounting bracket A13 and its output shaft is connected to the rotating shaft of the gears A141. A movable column 21 is fixed on the gear belt A142. The movable column 21 is movably disposed in the sliding hole of the rectangular sliding frame 20.

[0032] In this embodiment, the movable column 21 is moved by the transmission mechanism, which in turn drives the rectangular slide frame 20 and the movable rod 22 to move up and down. The movable rod 22 then drives the stirring rod 33 to move, thereby increasing the stirring range of the stirring rod 33 and ensuring the stirring effect on the asphalt.

[0033] Example 3

[0034] like Figure 2 As shown, the road paving device proposed in this invention, compared with Embodiment 2, further includes a mounting frame B16 set on the housing 1. Gears B151 are rotatably mounted on both the upper and lower ends of the mounting frame B16. A gear belt B152 is connected between the two gears B151. A transmission rod 17 is connected between the gears B151 and the gears A141 at the corresponding height. A lifting block 18 is fixed on the gear belt B152. A pressure plate 23 is set on the side of the housing 1 away from the U-shaped frame A2. A guide rod A24 is connected to the pressure plate 23. A fixing block 25 is set on the housing 1. The top end of the guide rod A24 movably passes through the fixing block 25 and is connected to a limit block A26. A lifting frame 19 is connected to the pressure plate 23.

[0035] A U-shaped frame B28 is provided at the bottom of the casing 1, and a pressure roller 29 is rotatably mounted on the U-shaped frame B28.

[0036] In this embodiment, the machine box 1 drives the pressure roller 29 to roll during movement, thereby flattening the road surface. The transmission rod 17 enables the transmission mechanism to drive the gear belt B152 to rotate during operation. The gear belt B152 drives the lifting block 18 to move. When the lifting block 18 begins to contact the lifting frame 19, the lifting frame 19 is lifted up, and the lifting frame 19 drives the pressure plate 23 to rise. When the lifting block 18 begins to rotate downward, the lifting block 18 begins to separate from the lifting frame 19. The pressure plate 23 falls rapidly under the action of gravity, and the gravitational potential energy is converted into kinetic energy, thereby improving the compaction effect on the road surface.

[0037] The present invention also proposes a method for laying the above-mentioned road paving device, comprising the following steps:

[0038] S1. Adjust the positions of the two pressure sensors 12 according to the paving range of the road. Drive the two slide plates 11 to move closer or further apart through the set power component B. The slide plates 11 then drive the pressure sensors 12 to move. When the moving slider 3 contacts the pressure sensor 12 on either side, the power component B starts to drive the moving slider 3 to turn the direction and move.

[0039] S2. The moving slider 3 is driven to move by the set power component A, thereby driving the feeding nozzle 4 to reciprocate during the movement of the machine box 1, so as to ensure the uniformity of the material feeding of the equipment.

[0040] S3. During the movement of the slider 3, the ball 36 and the mounting rod 6 move. During the movement of the mounting rod 6, the lever 7 can move the asphalt, so that the asphalt is spread evenly on the road surface. At the same time, the ball 36 moves on the protrusion 10, so that the wedge block 35 repeatedly pushes the mounting rod 6 to move. Under the elastic force of the elastic component, the mounting rod 6 can be driven to move back and forth, thereby improving the asphalt moving effect.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
