Description

Technical Field

[0001] This invention relates to the field of road leveling technology, and in particular to a thermoplastic road leveling construction rolling device. Background Technology

[0002] Thermoplastic roads use plastic instead of asphalt, mixing it with several materials such as gravel, sand, and limestone to create precast slabs for paving roads, thus replacing traditional asphalt roads. This plastic is not made from fresh, intact plastic, but rather from recycled, non-degradable plastic waste processed into precast slabs. The interior of the plastic road is hollow, allowing for the installation of water pipes, cables, and network cables. Its lightweight structure gives it strong load-bearing capacity and earthquake resistance, while also providing excellent drainage performance.

[0003] The existing thermoplastic rollers have the following disadvantages when leveling: (1) When leveling and compacting the road surface, gravel, dust and other debris are scattered on the road surface, which not only affects the compaction effect of the road surface, but also easily adheres to the rollers, affecting their use; (2) The rollers are mostly fixed, and their pressure on the ground is not easy to adjust, which limits their use.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. This device is equipped with a second gear, a first gear, and a cleaning brush that work together. Before the road is flattened, the two drive wheels can be driven to rotate by starting the drive vehicle. With the cooperation of the two first gears and the second gear, the cleaning brush is driven to rotate back and forth to clean the road before flattening, so as to avoid leaving large sand and gravel and other impurities on the road, ensuring the quality of compaction, and at the same time preventing sand and gravel from wearing down the flattening roller.

[0010] 2. This device is equipped with a cleaning brush that is easy to adjust in height. Users can rotate the movable column to move the cleaning brush up or down, thereby changing the height of the cleaning brush. This allows users to change the position of the cleaning brush according to the actual needs of flattening the road surface, making it highly adaptable and easy to use.

[0011] 3. This device is equipped with a push rod, a first movable rod and an air tank. When the fixed ring rotates and drives the push rod to rotate back and forth, it will drive the push rod to push the first movable rod back and forth. The first movable rod will squeeze the air in the air tank through the piston pad and discharge it to the ground through the exhaust pipe to perform secondary cleaning of the ground, further blowing away some smaller impurities and dust, and ensuring the flattening quality of the road surface.

[0012] 4. This device is equipped with a pressure roller that is easy to adjust in position. Users can adjust the position of the pressure roller according to the actual road flattening needs, thereby changing the pressure of the pressure roller on the ground. This makes it easy to adapt to the flattening needs of different roads and has high adaptability.

[0013] 5. This device is equipped with a scraper. The torsion spring can be pushed by the shaft to the scraper to be close to the circumferential end of the flattening roller. When the flattening roller rotates and flattens, the scraper will clean the circumferential end of the flattening roller in time, so as to avoid the accumulation of too many impurities on the flattening roller, which will cause wear on the flattening roller during flattening, resulting in unevenness and affecting the service life of the flattening roller. Timely cleaning is essential.

[0014] 6. This device uses a combination of a fixed block and an adsorption magnetic block to store the scraper when it is not needed. The user can rotate the scraper, which will cause the C-shaped plate to rotate and be adsorbed under the adsorption magnetic block. This keeps the scraper under the fixed block and prevents it from being detached from the flattening roller. The operation is simple, quick and convenient. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example: To achieve the goal of not affecting the flattening function of the roller, this example provides a thermoplastic road leveling and compaction equipment. See [link to example]. Figures 1 to 8Specifically, it includes a drive vehicle 1 and four drive wheels 11, each of which is fixedly installed at the lower end of the drive vehicle 1. A connecting shaft 12 is fixedly installed between every two drive wheels 11. The drive vehicle 1 uses a cleaning mechanism to facilitate road cleaning and a flattening mechanism to facilitate road leveling. The cleaning mechanism includes a rotating shaft 2, a fixed crossbar 3, and an air tank 4. The rotating shaft 2 is rotatably installed at the lower end of the drive vehicle 1. A second gear 22 is fixedly installed at the lower end of the rotating shaft 2. Two first gears 13 are fixedly installed on the circumferential end of the connecting shaft 12 located on one side of the second gear 22. A fixing ring 21 is fixedly installed on the circumferential end of the rotating shaft 2. A connecting rod 24 is fixedly installed on the side end of the fixing ring 21. Rod 3 is fixedly installed on the side end of connecting rod 24. Two mounting rings 41 are fixedly installed on the circumferential end of gas tank 4. Both mounting rings 41 are fixedly installed on the lower end of drive vehicle 1. Half of the two first gears 13 are provided with teeth. Both first gears 13 mesh with second gears 22. Push rod 23 is also fixedly installed on the circumferential end of fixed ring 21. The upper end of fixed crossbar 3 is provided with a first threaded groove 31. The upper end of fixed crossbar 3 and both sides of the first threaded groove 31 are provided with cylindrical grooves 32. A cleaning brush 33 is provided below fixed crossbar 3. The upper end of cleaning brush 33 is rotatably mounted with a first threaded rod 34. The first threaded rod 34 is rotatably mounted on the inner wall of the first threaded groove 31. The thread on the first threaded rod 34 and the first thread The groove 31 is matched, and two movable columns 35 are fixedly installed on the upper end of the fixed crossbar 3. The two movable columns 35 are slidably installed on the inner sidewalls of the two cylindrical grooves 32. Limit rings 36 are fixedly installed on the upper ends of the two movable columns 35. The user can first adjust the height of the cleaning brush 33 by rotating the first threaded rod 34. The first threaded rod 34 will move up or down in the first threaded groove 31 when rotated in the forward or reverse direction. The upward or downward movement of the first threaded rod 34 drives the cleaning brush 33 to move. The movement of the cleaning brush 33 drives the two movable columns 35 to slide in the first threaded groove 31, thereby changing the height of the cleaning brush 33. After the adjustment of the cleaning brush 33 is completed, the user can stop rotating the first threaded rod 34. When the user is leveling the road, he / she can... First, start the drive vehicle 1. The connecting shaft 12 starts, driving each drive wheel 11 to rotate. The rotation of each drive wheel 11 drives the connecting shaft 12 to rotate, which in turn drives the two first gears 13 to rotate. Since the two first gears 13 mesh with the second gear 22, and half of the first gear 13 has teeth, the rotation of the first gear 13 will drive the second gear 22 to rotate. The rotation of the second gear 22 will drive the fixed ring 21 to rotate. The rotation of the fixed ring 21 will drive the first threaded rod 34 to rotate through the fixed crossbar 3. The rotation of the first threaded rod 34 will drive the cleaning brush 33 to rotate. When the teeth on one side of the first gear 13 rotate away from the second gear 22, the teeth on the other side of the first gear 13 will mesh with the second gear 22, and the second gear 22 will rotate in the opposite direction.This causes cleaning brush 33 to rotate in the opposite direction, thus repeatedly driving cleaning brush 33 to clean the road surface before it is flattened;

[0027] A piston pad 42 is slidably mounted on the inner wall of the gas tank 4. A spring 45 is fixedly mounted between the piston pad 42 and the inner wall of the gas tank 4. A first movable rod 43 is fixedly mounted on the side end of the piston pad 42. A one-way air intake valve 49 is provided on the gas tank 4. A fixed pipe 46 is fixedly mounted on the side end of the gas tank 4. An exhaust pipe 47 is fixedly mounted on the end of the fixed pipe 46. A fixed post 48 is fixedly mounted between the exhaust pipe 47 and the lower end of the drive vehicle 1. During the reciprocating rotation of the fixed ring 21, the fixed ring 21 will drive the push rod 23 to reciprocate. Both ends of the push rod 23 are beveled. When the push rod 23 rotates and contacts the first movable rod 43, the first movable rod 43... Both ends are also beveled. When the push rod 23 rotates and contacts the first movable rod 43, it will push the first movable rod 43 to move. The movement of the first movable rod 43 will push the piston pad 42 to move inside the gas tank 4. The movement of the piston pad 42 will squeeze the air in the gas tank 4 and discharge it from the fixed pipe 46. Finally, the gas will pass through the fixed pipe 46 to the exhaust pipe 47 and then be blown to the ground through the exhaust pipe 47. When the push rod 23 rotates away from the end of the first movable rod 43, the spring 45 is no longer under pressure and rebounds. The spring 45 rebounds and pushes the piston pad 42 to move and reset again. This process is repeated to squeeze the gas in the gas tank 4 and blow it to the ground through the exhaust pipe 47, thus cleaning the ground a second time.

[0028] The flattening mechanism includes a first mounting plate 5, a second mounting plate 6, and an L-shaped fixing rod 7. There are two first mounting plates 5, both fixedly mounted on the side ends of the drive vehicle 1. A rectangular groove 51 is formed through the side ends of both first mounting plates 5. There are also two second mounting plates 6, each with a slider 62 fixedly mounted on its side ends. Both sliders 62 are slidably mounted on the inner wall of the rectangular groove 51. A second stop rod 66 is fixedly mounted on the upper ends of both second mounting plates 6. The L-shaped fixing rod 7 is fixedly mounted on the side ends of the second stop rod 66. A first stop rod 52 is fixedly mounted between the two first mounting plates 5. A mounting groove 53 is formed through the upper end of the first stop rod 52. A second threaded rod 54 is rotatably mounted on the inner wall of the mounting groove 53. Rotary grooves 61 are formed through the side ends of both second mounting plates 6 and sliders 62. A flattening roller is provided between the two sliders 62. 63. The flattening roller 63 is rotatably installed on the inner wall of each rotating groove 61. The drive motor 64 is fixedly installed on the side end of the second mounting plate 6. The flattening roller 63 is fixedly installed on the side end of the drive motor 64. The upper end of the second stop rod 66 is provided with a second threaded groove 65. The second threaded rod 54 is rotatably installed on the inner wall of the second threaded groove 65. During flattening, the pressure of the flattening roller 63 on the road surface can be adjusted. The user can rotate the second threaded rod 54. The rotation of the second threaded rod 54 drives the second stop rod 66 to move downward through the second threaded groove 65. The downward movement of the second stop rod 66 drives the two second mounting plates 6 to move downward. The downward movement of the two second mounting plates 6 drives the flattening roller 63 to move downward through the rotating groove 61. When the flattening roller 63 moves downward and contacts the ground, the user can continue to rotate the second threaded rod 54 as needed, thereby driving the flattening roller 63 to continue to move downward and increase the pressure of the flattening roller 63 on the ground.

[0029] A fixing block 71 is fixedly installed on the side end of the L-shaped fixing rod 7, and an adsorption magnetic block 72 is fixedly installed on the lower end of the fixing block 71. A cylindrical slot 73 is opened through the end of the L-shaped fixing rod 7. A shaft 76 is rotatably installed on the inner wall of the cylindrical slot 73. A torsion spring 77 is fixedly installed between the shaft 76 and the cylindrical slot 73. The same C-shaped plate 75 is fixedly installed on both sides of the shaft 76. A scraper 74 is fixedly installed on the lower end of the C-shaped plate 75. The user can start the drive motor 64 when the drive vehicle 1 is running. The start-up mechanism drives the installation groove 53 to rotate and flatten the road. When the flattening roller 63 rotates and flattens, it passes by the scraper 74. The scraper 74 scrapes and cleans the rotating flattening roller 63. When the scraper 74 is not needed, the user can rotate the scraper 74. The rotation of the scraper 74 drives the C-shaped plate 75 to rotate. The rotation of the C-shaped plate 75 drives the shaft 76 to rotate in the cylindrical groove 73. At this time, the torsion spring 77 deforms. When the C-shaped plate 75 rotates and is attracted to the magnetic block 72, the scraper 74 is limited and no longer contacts the flattening roller 63.

[0030] Working principle:

[0031] First, the user can adjust the height of the cleaning brush 33 by rotating the first threaded rod 34. Rotating the first threaded rod 34 forward or backward will move it up or down within the first threaded groove 31. This movement of the first threaded rod 34 moves the cleaning brush 33, which in turn causes the two movable columns 35 to slide within the first threaded groove 31, thus changing the height of the cleaning brush 33. After adjusting the cleaning brush 33, the user can stop rotating the first threaded rod 34. When leveling the road, the user can first start the drive vehicle 1. The connecting shaft 12 starts, causing each drive wheel 11 to rotate. The rotation of each drive wheel 11 causes the connecting shaft 12 to rotate, which in turn causes the two movable columns 35 to slide within the first threaded groove 31. When gear 13 rotates, the two first gears 13 and the second gear 22 mesh together, and half of the first gear 13 has teeth. When the first gear 13 rotates, it will drive the second gear 22 to rotate. The rotation of the second gear 22 will drive the fixed ring 21 to rotate. The rotation of the fixed ring 21 will drive the first threaded rod 34 to rotate through the fixed crossbar 3. The rotation of the first threaded rod 34 will drive the cleaning brush 33 to rotate. When the teeth on one side of the first gear 13 rotate away from the second gear 22, the teeth on the other side of the first gear 13 will mesh with the second gear 22 and the second gear 22 will rotate in the opposite direction, thereby driving the cleaning brush 33 to rotate in the opposite direction. This reciprocating motion drives the cleaning brush 33 to clean the road before it is flattened.

[0032] This device, through the cooperation of a second gear 22, a first gear 13 and a cleaning brush 33, can drive the two drive wheels 11 to rotate when the drive vehicle 1 is started before the road is flattened. Under the cooperation of the two first gears 13 and the second gear 22, the cleaning brush 33 is driven to rotate back and forth to clean the road before flattening, so as to avoid leaving large sand and gravel and other impurities on the road, ensure the quality of compaction, and at the same time prevent sand and gravel from wearing down the flattening roller 63.

[0033] This device features a height-adjustable cleaning brush 33. Users can rotate the movable column 35 to move the cleaning brush 33 up or down, thereby changing the height of the cleaning brush 33. This allows users to adjust the position of the cleaning brush 33 according to the needs of flattening the road surface, making it highly adaptable and easy to use.

[0034] In the second step, during the reciprocating rotation of the fixed ring 21, the fixed ring 21 will drive the push rod 23 to reciprocate. Both ends of the push rod 23 are beveled. When the push rod 23 rotates and contacts the first movable rod 43, since both ends of the first movable rod 43 are also beveled, the push rod 23 will push the first movable rod 43 to move when it contacts the first movable rod 43. The movement of the first movable rod 43 will push the piston pad 42 to move inside the gas tank 4. The movement of the piston pad 42 will squeeze the air in the gas tank 4 and discharge it from the fixed pipe 46. Finally, the gas will pass through the fixed pipe 46 to the exhaust pipe 47, and then be blown to the ground through the exhaust pipe 47. When the push rod 23 rotates away from the end of the first movable rod 43, the spring 45 is no longer under pressure and rebounds. The spring 45 rebounds and pushes the piston pad 42 to move and reset again. In this way, the gas in the gas tank 4 is squeezed and blown to the ground through the exhaust pipe 47, and the ground is cleaned a second time.

[0035] This device is designed with a push rod 23, a first movable rod 43, and an air tank 4 working together. As the fixed ring 21 rotates, it drives the push rod 23 to rotate back and forth, which in turn drives the push rod 23 to push the first movable rod 43 back and forth. The first movable rod 43 compresses the air in the air tank 4 through the piston pad 42 and discharges it to the ground through the exhaust pipe 47, performing secondary cleaning of the ground and further blowing away some smaller impurities and dust to ensure the quality of road surface compaction.

[0036] Thirdly, during the flattening process, the pressure of the flattening roller 63 on the road surface can be adjusted. The user can rotate the second threaded rod 54. The rotation of the second threaded rod 54 drives the second stop rod 66 to move downward through the second threaded groove 65. The downward movement of the second stop rod 66 drives the two second mounting plates 6 to move downward. The downward movement of the two second mounting plates 6 drives the flattening roller 63 to move downward through the rotating groove 61. When the flattening roller 63 moves downward and contacts the ground, the user can continue to rotate the second threaded rod 54 as needed, thereby driving the flattening roller 63 to continue to move downward and increase the pressure of the flattening roller 63 on the ground.

[0037] This device is equipped with a flattening roller 63 that is easy to adjust in position. Users can adjust the position of the flattening roller 63 according to the actual road flattening needs, thereby changing the pressure of the flattening roller 63 on the ground. This makes it easy to adapt to the flattening needs of different roads and has high adaptability.

[0038] Fourth step: When the driving vehicle 1 is running, the user can start the drive motor 64. The drive motor 64 starts and drives the mounting groove 53 to rotate and flatten the road. When the flattening roller 63 rotates and flattens, it will pass the scraper 74. The scraper 74 will scrape and clean the rotating flattening roller 63. When the scraper 74 is not needed, the user can rotate the scraper 74. The rotation of the scraper 74 drives the C-shaped plate 75 to rotate. The rotation of the C-shaped plate 75 drives the shaft 76 to rotate in the cylindrical groove 73. At this time, the torsion spring 77 deforms. When the C-shaped plate 75 rotates and is attracted to the magnetic block 72, the scraper 74 is limited and no longer contacts the flattening roller 63.

[0039] This device is equipped with a scraper 74, and a torsion spring 77 can be pushed by a shaft 76 to the scraper 74 to be close to the circumferential end of the flattening roller 63. When the flattening roller 63 rotates and flattens, the scraper 74 will clean the circumferential end of the flattening roller 63 in time, so as to avoid the accumulation of too many impurities on the flattening roller 63. This will prevent the flattening roller 63 from being worn during flattening, resulting in unevenness and affecting the service life of the flattening roller 63. Timely cleaning is essential.

[0040] This device uses a fixed block 71 and an adsorption magnetic block 72 to work together. When the scraper 74 is not needed, it can be stored away. The user can rotate the scraper 74, which will cause the C-shaped plate 75 to rotate and be adsorbed under the adsorption magnetic block 72. This way, the scraper 74 is stored under the fixed block 71 and is no longer detached from the flattening roller 63. The operation is simple, quick and convenient.
