Description

Technical Field

[0001] This invention relates to the field of highway maintenance technology, specifically to a highway pavement maintenance device and its usage method. Background Technology

[0002] "Highway maintenance" refers to the upkeep and maintenance of highways. Upkeep focuses on the entire process from the time a highway is built and opened to traffic, while maintenance focuses on repairing damaged parts. After a highway is built and opened to traffic, it will gradually lose its quality due to wear and impact from wheels, erosion and weathering from natural forces such as rainstorms, floods, wind and sand, ice and snow, sun exposure and melting ice, as well as human damage and some defects left over from the construction. Therefore, after a highway is built and opened to traffic, maintenance and repair measures must be taken and it must be continuously updated and improved.

[0003] A search revealed that utility model CN211285464U relates to the field of highway maintenance technology and discloses a highway pavement maintenance device, including a vehicle body. A bracket is fixedly installed on the front of the vehicle body, and a sleeve is fixedly installed inside the bracket. A turntable ring is movably installed inside the sleeve. When this highway pavement maintenance device is used for ice breaking, the motor is first started. The motor rotation drives the mounting base to rotate, and the first and second connecting rods drive the side plate to move the rollers on the sleeve. As the rollers move from the lowest point to the highest point of the sleeve, the first connecting rod rises along the slide groove with the rollers, thereby dragging the ice-breaking hammer. When moving from the highest point to the lowest point, the ice-breaking hammer breaks the ice on the ground under the impact of the descent. In this way, multiple sets of rollers move undulatingly on the sleeve, driving the ice-breaking hammer to break the ice on the opposite side. Then, a scraper on the rear side scrapes away the snow, achieving high efficiency.

[0004] Although this type of highway pavement maintenance device can achieve ice-breaking function, it still has the following drawbacks:

[0005] 1. The ice-breaking method relies solely on the gravity of the ice hammer, without any other auxiliary ice-breaking devices, resulting in poor ice-breaking performance.

[0006] 2. Even after the ice is broken, some ice fragments will still stick to the ground and cannot be cleaned up. This can cause vehicles to bump or even overturn when driving on the road, which is quite dangerous.

[0007] Therefore, we propose a highway pavement maintenance device and its usage method. Summary of the Invention

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. This invention uses multiple collection boxes to continuously scoop up ice fragments from the ground and feed them into the collection box for further crushing, preventing the ice fragments from freezing on the road surface.

A third spring 63 is fixedly connected between the bottom of the extension block 64 and the bottom inner wall of the first mounting slot 61. One end of the extension block 64 passes through the mounting hole 62 and is used in conjunction with the support plate 58.

[0069] like Figure 11 , Figure 9 and Figure 10As shown, the lifting assembly includes a fifth rotating shaft 26 rotatably connected to the inner wall of one side of the vehicle body 1. A half gear 38 is fixedly sleeved on the outer wall of the fifth rotating shaft 26. A double-sided rack 39 is fixedly connected to the top of the vertical rod 27, and the double-sided rack 39 meshes with the half gear 38. The top of the double-sided rack 39 is fixedly connected to the same first spring 42 between it and the top inner wall of the vehicle body 1. A groove 14 is provided at the bottom of the vehicle body 1.

The outer wall of each of the first rotating shafts 13 is fixedly fitted with a second synchronous pulley 36. The outer walls of the three second synchronous pulleys 36 are fitted with the same second synchronous belt 37. The inner walls of both sides of the vehicle body 1 are rotatably connected to the same third rotating shaft 24. The outer walls of the third rotating shaft 24 and the fourth rotating shaft 25 are fixedly fitted with first synchronous pulleys 35. The outer walls of the two first synchronous pulleys 35 are fitted with the same first synchronous belt 34.

The rotating roller 20 located below can drive the first rotating shaft 13 to rotate. The first rotating shaft 13, through the transmission of the second synchronous pulley 36 and the second synchronous belt 37, can drive the fifth rotating shaft 26 and the fourth rotating shaft 25 to rotate. At this time, the fifth rotating shaft 26 drives the half gear 38 to rotate, the half gear 38 drives the double-sided rack 39 to move vertically upward, the double-sided rack 39 drives the vertical rod 27 to move vertically upward and squeeze the first spring 42, the vertical rod 27 drives the first horizontal plate 28 to move vertically upward, and the first horizontal plate 28 drives multiple ice-breaking needles 4 to move vertically upward. When the half gear 38 is no longer meshed with the double-sided rack 39, the first horizontal plate 28 drives the ice-breaking needles 4 to move vertically downward under the elastic force of the first spring 42, and further break the ice.

[0070] like Figure 11 , Figure 12 and Figure 13As shown, the ice-breaking assembly includes multiple rectangular boxes 46 fixedly connected to the bottom of the sliding plate 44. The rectangular boxes 46 slide through the vehicle body 1 and are fixedly connected to multiple cylinders 30. A fixed tip 10 is fixedly connected to the bottom of each cylinder 30. Two symmetrically arranged tension springs 45 are fixedly connected between the top of the sliding plate 44 and the inner top wall of the vehicle body 1. A second horizontal plate 31 is fixedly connected to one side of the sliding plate 44. A sixth rotating shaft 41 is rotatably connected to the inner wall of one side of the vehicle body 1. A spur gear 40 meshing with a double-sided rack 39 is fixedly connected to one end of the sixth rotating shaft 41. A single-sided rack 43 meshing with the spur gear 40 is fixedly connected to one end of the second horizontal plate 31. When the double-sided rack 39 rises, it can drive the spur gear 40 to rotate. The spur gear 40 drives the single-sided rack 43 to move vertically downwards. The single-sided rack 43 drives the second horizontal plate 31 to move vertically downwards. The second horizontal plate 31 drives the sliding plate 44 to move vertically downwards. The sliding plate 44 drives multiple rectangular boxes 46 to move vertically downwards and stretches the tension spring 45. The rectangular boxes 46 drive the cylinder 30 to move vertically downwards, and the cylinder 30 drives the fixed tip 10 to move vertically downwards, thus performing initial crushing of the ice. A salt box 29 is fixedly connected inside the vehicle body 1. The top of the salt box 29 is fixedly connected to the feed pipe 17, and the top of the feed pipe 17 extends to the top of the vehicle body 1. A threaded plug 2 is threadedly connected inside the feed pipe 17. A second triangular block 51 is fixedly connected to the bottom inner wall of the salt box 29.

The third round hole 50 is connected to the second round hole 49. The outer wall of the fixed tip 10 has multiple first round holes 48. The bottom inner wall of the fixed tip 10 is fixedly connected to a conical block 47. Salt can be loaded into the salt box 29 through the feed pipe 17. When the rectangular box 46 descends, the third round hole 50 will connect with the second round hole 49. At this time, the salt enters the inside of the cylinder 30. After the cylinder 30 enters the inside of the fixed tip 10, it is discharged through the outside of the first round hole 48 and sprinkled into the broken hole of the fixed tip 10, thereby increasing the melting speed of the ice. The conical block 47 can prevent the salt particles from accumulating.

[0071] Working principle:

[0072] When in use, the servo motor 6 is started. The output shaft of the servo motor 6 drives the rotating roller 20 to rotate. The rotating roller 20 drives the conveyor belt 9 to drive. The conveyor belt 9 drives multiple connecting blocks 19 to drive. The connecting blocks 19 carry the collection box 8 to continuously drive along the connecting blocks 19. At this time, the collection box 8 located at the bottom can scoop up the broken ice blocks on the ground and continuously convey them upward. The setting of the inclined chute 21 can reduce the difficulty of scooping up the ice blocks.

[0073] The rotating roller 20 located below can drive the first rotating shaft 13 to rotate. The first rotating shaft 13 can drive the fifth rotating shaft 26 and the fourth rotating shaft 25 to rotate through the transmission of the second synchronous pulley 36 and the second synchronous belt 37. At this time, the fifth rotating shaft 26 drives the half gear 38 to rotate. The half gear 38 drives the double-sided rack 39 to move vertically upward. The double-sided rack 39 drives the vertical rod 27 to move vertically upward and squeeze the first spring 42. The vertical rod 27 drives the first horizontal plate 28 to move vertically upward. The first horizontal plate 28 drives multiple ice-breaking needles 4 to move vertically upward. When the half gear 38 is no longer meshed with the double-sided rack 39, the first horizontal plate 28 drives the ice-breaking needles 4 to move vertically downward under the elastic force of the first spring 42 to further break the ice.

[0074] As the double-sided rack 39 rises, it drives the spur gear 40 to rotate. The spur gear 40 drives the single-sided rack 43 to move vertically downward. The single-sided rack 43 drives the second horizontal plate 31 to move vertically downward. The second horizontal plate 31 drives the sliding plate 44 to move vertically downward. The sliding plate 44 drives multiple rectangular boxes 46 to move vertically downward and stretches the tension spring 45. The rectangular boxes 46 drive the cylinder 30 to move vertically downward. The cylinder 30 drives the fixed tip 10 to move vertically downward, thus performing the initial crushing of the ice.

[0075] Meanwhile, salt can be fed into the salt box 29 through the feed pipe 17. When the rectangular box 46 descends, the third round hole 50 will connect with the second round hole 49. At this time, the salt enters the inside of the cylinder 30. After the cylinder 30 enters the inside of the fixed tip 10, it is discharged through the outside of the first round hole 48 and sprinkled into the broken hole of the fixed tip 10, which can increase the melting speed of the ice. The cone block 47 can prevent the accumulation of salt particles.

[0076] The rising collection box 8 continuously feeds crushed ice from the ground into the collection box 5. The U-shaped baffle 7 allows ice to fly out. After entering the collection box 5, the ice accumulates on the support plate 58. As the ice gradually accumulates, the support plate 58 compresses the second spring 57 and pushes the two extension blocks 64 to move vertically downwards. This causes the locking rod 59 to move vertically downwards and no longer engage with the locking slot 60. At the same time, the electromagnetic clutch 53 is activated. Simultaneously, the fourth rotating shaft 25 drives the third rotating shaft 24 to rotate through the first synchronous pulley 35 and the first synchronous belt 34. The third rotating shaft 24 drives the second rotating shaft 18 to rotate through the second bevel gear 33 and the first bevel gear 32. This allows the second rotating shaft 18 to transmit power to the rotating rod 52. At this time, the rotating rod 52 drives the positioning rod 55 to rotate. The positioning rod 55 is no longer engaged with the positioning slot 56, allowing the collection box 5 to be removed for replacement.
