Description

Technical Field

[0001] The invention relates to the technical field of highway construction, in particular to a self-adjusting elevation type concrete road surface leveling device. Background Art

[0002] After the construction of the concrete roadbed is completed, baffles must first be placed on both sides of the road. The function of these baffles is to define the paving boundaries of the concrete. Subsequently, the concrete is evenly poured and laid on the prepared roadbed until the concrete surface is flush with the baffles. After paving is completed, a leveling device is needed to level the concrete pavement. In the prior art, a roller paver is used to level the pavement. When the existing roller paver is leveling the pavement, excess concrete on the concrete pavement will continue to accumulate in front of the roller paver, and then flow from both sides of the roller of the roller paver to both sides of the road (i.e., both sides of the baffles). If it is processed, it is necessary to follow the roller paver in real time, which increases the workload. If it is not processed, it will affect the removal of the baffles after it solidifies, which also increases the workload.

[0029] In the prior art, a roller paver is used to level the road surface.

If it is processed, it is necessary to follow up the roller paver in real time, which increases the workload. If it is not processed, it will affect the removal of the baffle after it solidifies, which also increases the workload. In addition, if the overflowed concrete (i.e. the concrete flowing out from both sides of the roller) is not processed in time, it will also cause a waste of resources.

[0032] See also Figure 1 and Figure 6 The mixing and feeding mechanism 15 includes a third motor 1501, which is fixedly connected to the lower side of the storage shell 1401 through a mounting frame.

The connection between the feeding bin 1504 and the storage shell 1401 is located on the upper side of the stirring blade 1503 in the vertical direction to prevent concrete from solidifying.

[0033] When it is necessary to use the device to level a concrete pavement (hereinafter referred to as the pavement), the user first measures the height of the baffles on both sides of the pavement, and then rotates the two threaded rods 8. Taking the front threaded rod 8 as an example, the threaded rod 8 drives the adjustment frame 6 and the power wheel 7 to move downward together through the thread until the vertical distance between the lower side of the power wheel 7 and the lower side of the leveling roller 3 is equal to the baffle height. The user stops rotating the threaded rod 8. At this time, the height of the device is adjusted to the standard height. The user sets up the device on the pavement. At this time, the two temporary storage shells 4 are respectively attached to the front and rear baffles, and the preparation work is completed. The threaded rod 8 cooperates with the adjustment frame 6 to synchronously adjust the distance between the power wheel 7 and the leveling roller 3 according to the thickness of the pavement, thereby improving the scope of application of the device.

[0034] After the preparation work is completed, the user starts the first motor 2 and the second motor 11 at the same time. The first motor 2 drives the leveling roller 3 to rotate and level the excess concrete on the road surface. The output shaft of the second motor 11 drives the dispersion roller 12 to rotate through the pulley and belt. The dispersion roller 12 drives the gathering roller 13 to rotate through the pulley and belt. Then the user drives the two power wheels 7 to rotate at a fixed speed through the guide vehicle 101, and the power wheel 7 drives the device to move to the right as a whole. During the movement of the device to the right, the excess concrete on the road surface first contacts the gathering roller 13. As the gathering roller 13 rotates, the two spiral plates thereon continuously gather the concrete to the middle of the road surface. During this process, if the concrete encounters a pothole on the road surface, the concrete will fill the pothole on the road surface until the concrete loses contact with the spiral plate on the gathering roller 13. At this time, the concrete gathered in the middle of the road surface moves to the left relative to the device to the right side of the dispersion roller 12 through the part of the middle of the gathering roller 13 where the spiral plate is not provided.

[0035] When the concrete gathered in the middle of the road surface contacts the dispersion roller 12, the dispersion roller 12 diffuses to both sides of the road surface through the two spiral plates thereon. In this process, if the concrete encounters a pit on the road surface that has not been completely filled, the concrete will fill the pit on the road surface again until the excess concrete is driven by the spiral plates on the dispersion roller 12 to move to the two temporary storage shells 4 on the front and rear sides respectively and accumulate and store. After the road surface is roughly treated by the gathering roller 13 and the dispersion roller 12, a large amount of excess concrete on it has been moved to the two temporary storage shells 4. In the above process, the rough treatment of the concrete by the gathering roller 13 and the dispersion roller 12 makes the moving path of the concrete cross-shaped. After two cross-overlapping of the concrete, the fullness of the road surface is ensured. The excess concrete squeezed out during the working process of the device is automatically collected through the temporary storage shell 4 to prevent the excess concrete on the road surface from being driven to the sides of the road and affecting subsequent work. At the same time, it prevents the waste of concrete and improves the practicality of the device.

[0036] As the amount of concrete in the two temporary storage shells 4 gradually increases, the user controls the two electric rotating shafts 1402 to rotate. Taking the front electric rotating shaft 1402 as an example, the electric rotating shaft 1402 drives the two first rotating rods 1404 to rotate through the pulley and the belt, and the two first rotating rods 1404 drive the two spiral plates 1405 to rotate, so that the concrete in the temporary storage shell 4 gradually moves upward to the storage shell 1401 through the two fixed cylinders 1403. When the concrete enters the storage shell 1401, the user starts the third motor 1501, and the output shaft of the third motor 1501 drives the frontmost rotating shaft 1502 to rotate, and the frontmost rotating shaft 1502 drives all the rotating shafts 1502 to rotate in turn through the pulley and the belt, and the rotating shaft 1501 is rotated. 02 drives the adjacent stirring blades 1503 to rotate, thereby stirring and mixing the concrete entering the storage shell 1401. As the amount of concrete in the storage shell 1401 gradually increases (that is, as the device continues to move to the right), after the height of the concrete in the storage shell 1401 exceeds the connection between the storage shell 1401 and the replenishing bin 1504, the concrete in the storage shell 1401 flows through the replenishing bin 1504 to the road surface on the right side of the device, thereby replenishing the road surface that has not been leveled. After the excess concrete is mixed by the stirring blades 1503, the concrete is replenished to the road surface again through the replenishing bin 1504, ensuring that there is sufficient concrete on the road surface for leveling, preventing potholes on the road surface, and improving the integrity of the overall work flow of the device.

[0037] After the rough treatment of the road surface is completed, as the device continues to move to the right, the leveling roller 3 gradually contacts the roughly treated road surface, and the continuously rotating leveling roller 3 levels the road surface again (i.e., fine treatment). During this process, excess concrete also gradually moves into the temporary storage shells 4 on both sides. The user repeats the above steps to continuously level the road surface until the road surface is leveled. The user discharges the excess concrete in the storage shell 1401 to the storage position, and the user removes the device from the concrete road surface and turns off all power. At this time, the use of the device is completed.

[0040] See also Figure 7-Figure 12A fourth motor 1807 is fixedly connected to the upper side of the frame 1, and the output shaft of the fourth motor 1807 is fixedly connected to the first transmission wheel 1808, and the first transmission wheel 1808 is a truncated cone friction wheel.

The second sliding block 1817 is rotatably connected to the fourth rotating rod 1818. The third rotating rod 1816 and the adjacent fourth rotating rods 1818 are driven by pulleys and belts.

[0041] During the operation of the device, the two spiral plates on the dispersion roller 12 continuously rotate and move excess concrete into the two temporary storage shells 4. Taking the spiral plate on the front side of the dispersion roller 12 as an example, the first sliding block 17 contacts the front part of the spiral plate on the front side of the dispersion roller 12. As the spiral plate on the front side of the dispersion roller 12 continuously rotates, the spiral plate on the front side of the dispersion roller 12 squeezes and drives the first sliding block 17 to move forward, while squeezing the spring between the blocking plate 16 and the first sliding block 17. As the spiral plate on the front side of the dispersion roller 12 continues to rotate, the spiral plate on the front side of the dispersion roller 12 gradually loses its squeeze on the first sliding block 17, and the spring between the blocking plate 16 and the first sliding block 17 drives the first sliding block 17 to reset. In this state, the concrete sent out through the dispersion roller 12 is blocked by the first sliding block 17 so that the concrete will not stay on the baffles on both sides of the road surface, thereby preventing the normal movement of the device from being affected.

[0042] During the accumulation of concrete in the temporary storage shell 4, most of the concrete on the road surface is driven to the right half of the temporary storage shells 4 on both sides by the dispersion rollers 12. Taking the front temporary storage shell 4 as an example, after the concrete enters the temporary storage shell 4, the concrete squeezes and drives the right isolation membrane 1803 to move downward, and the isolation membrane 1803 squeezes and drives the adjacent sliding plate 1802 to move downward, and at the same time squeezes the spring between the right sliding plate 1802 and the adjacent first fixed shell 1801, and the right sliding plate 1802 drives the sliding frame 1804 to move downward, and the sliding frame 1804 drives the rack 1805 to move downward, and the rack 1805 meshes with the gear on the spoiler 1806 and drives the spoiler 1806 to rotate, thereby reducing the flow area on the lower side of the feeding bin 1504, until the amount of concrete on the right half of the temporary storage shell 4 tends to be stable, and the spoiler 180 6 stops rotating, at which time the sliding frame 1804 is located at the half of the sliding path on the adjacent first fixed shell 1801. When the excess concrete on the road surface increases, the amount of concrete in the right half of the temporary storage shell 4 increases, the concrete squeezes and drives the right isolation membrane 1803 to move downward, the isolation membrane 1803 drives the sliding frame 1804 and the rack 1805 to move downward together, the rack 1805 meshes with the gear on the spoiler 1806 and drives the spoiler 1806 to rotate, thereby reducing the flow area on the lower side of the feeding bin 1504 again (i.e. reducing the amount of concrete feeding), the spoiler 1806 cooperates with the feeding bin 1504, and the amount of concrete feeding is adjusted in real time according to the excess concrete on the concrete road surface, ensuring the excess concrete while preventing the excessive amount of concrete in the part that has not been leveled by the device, thereby affecting the leveling efficiency of the device.

[0043] During the preparation process, when the adjustment frame 6 and the power wheel 7 move downward, the adjustment frame 6 drives the second sliding block 1817 and the fourth rotating rod 1818 to move downward together, and in this process, the fourth rotating rod 1818 is driven by the pulley and belt thereon to gradually move to the right, and the fourth rotating rod 1818 drives the second sliding block 1817 to move to the right, while squeezing the spring between the second sliding block 1817 and the adjustment frame 6, thereby ensuring that the power wheel 7 and the adjacent third rotating rod 1816 always maintain a transmission state.

[0044] After the preparation work is completed, the user starts the fourth motor 1807, the output shaft of the fourth motor 1807 drives the first transmission wheel 1808 to rotate, the first transmission wheel 1808 drives the second transmission wheel 1810 to rotate by friction, the second transmission wheel 1810 drives the second rotating rod 1809 to rotate, the second rotating rod 1809 drives the two third rotating rods 1816 to rotate through the pulley and the belt, the third rotating rod 1816 drives the two power wheels 7 to rotate through the pulley and the belt, the two power wheels 7 drive the device to move to the right and level the road surface.

[0045] During the accumulation of concrete in the temporary storage shell 4, if the device moves too fast (i.e., the rough processing time of the dispersion roller 12 and the gathering roller 13 is insufficient), the amount of concrete driven by the leveling roller 3 will increase, thereby reducing the leveling effect of the road surface. To solve the above problem, the following operations need to be performed:

[0046] During the accumulation of concrete in the temporary storage shell 4, a small amount of concrete on the road surface is driven to the left half of the temporary storage shells 4 on both sides by the leveling roller 3. Taking the front temporary storage shell 4 as an example, the amount of concrete in the left half of the front temporary storage shell 4 increases, and the concrete squeezes and drives the left isolation membrane 1803 to move downward. The isolation membrane 1803 squeezes and drives the sliding frame 1804 to move downward, and at the same time squeezes the spring between the sliding frame 1804 and the adjacent first fixed shell 1801, and the sliding frame 1804 drives the first piston rod 1812 to move downward. The first piston rod 1812 The hydraulic oil on its lower side is squeezed into the third fixed shell 1813 through the pipeline. The hydraulic oil squeezes and drives the second piston rod 1814 to move backward. The second piston rod 1814 drives the second transmission wheel 1810 to move backward through the second fixed frame 1815, thereby decelerating the frame 1 and the parts thereon. The guide vehicle 101 still moves at a fixed speed at this time. The storage shell 1401 and the guide vehicle 101 slide relative to each other until the amount of concrete on the left half of the temporary storage shell 4 tends to be stable. At this time, the sliding frame 1804 slides on the adjacent first fixed shell 1801. The second transmission wheel 1810 is located at the half of the adjacent busbar of the first transmission wheel 1808. If the device travels too fast (i.e., the amount of excess concrete currently cannot be processed in time by the dispersion roller 12 and the gathering roller 13), the concrete extruded by the leveling roller 3 increases, and the amount of concrete on the left side of the temporary storage shell 4 increases synchronously. The front sliding plate 1802 drives the first piston rod 1812 to move downward, and the first piston rod 1812 squeezes and drives the hydraulic oil into the third fixed shell 1813. The hydraulic oil squeezes and drives the second transmission wheel 1810. 10 moves backward, thereby reducing the transmission ratio between the first transmission wheel 1808 and the second transmission wheel 1810, and further reducing the rotation speed of the power wheel 7 (that is, the travel speed of the device). The first transmission wheel 1808 and the second transmission wheel 1810 cooperate to adjust the overall travel speed of the device according to the amount of concrete discharged by the leveling roller 3 per unit time, thereby ensuring the stability of the amount of concrete near the working environment of the leveling roller 3 and improving the efficiency of leveling the concrete road surface. After the use of the device is completed, the user synchronously turns off the fourth motor 1807.
