Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, in particular to a road bridge asphalt pavement maintenance milling device. Background Art

[0002] Pavement milling machine is one of the main types of machinery for asphalt pavement maintenance and construction, and one of the main equipment for asphalt concrete pavement maintenance and construction. It is mainly used for excavation and renovation of asphalt concrete surface layers in highways, urban roads, airports, freight yards, etc. It can also be used to remove road surface defects such as bulges, oil waves, reticulation, rutting, etc. It can also be used to excavate road potholes and grooves, as well as roughen cement pavement and mill out surface misalignment.

[0003] At present, in the process of asphalt pavement maintenance, most of the asphalt pavement maintenance milling machines will generate dust during operation, which will then float into the air. If workers inhale it, it will have a certain impact on their health. In the process of the milling device cleaning the asphalt from the asphalt pavement and bringing it to the conveying device, some asphalt particles will be left behind. A scraper is needed to scrape the asphalt particles on the road surface so that the milling device can bring the lost asphalt particles to the conveying device. However, the scraper cannot scrape away all the asphalt particles on the asphalt pavement in the process of scraping the asphalt particles on the asphalt pavement. Some asphalt particles will be left on the asphalt pavement, thereby reducing the collection efficiency of the asphalt particles. Utility Model Content

One end of the conveying mechanism 5 is connected to the bottom end of the vehicle body 1 for conveying gravel after milling.

[0026] See attached Figure 1 and Figure 2 The milling mechanism 3 includes a milling cutter 31, a first motor 32, a support frame 33, a rotating shaft 34 and a lifting assembly 35. The lifting assembly 35 includes a hydraulic cylinder 351, a slide rail 352 and a slider 353. The support frame 33 is bolted to the slider 353. The first motor 32 is bolted to the support frame 33. The rotating shaft 34 is rotatably connected to the vehicle body 1. The rotating shaft 34 is coaxially connected to the output end of the first motor 32. The milling cutter 31 is rotatably connected to the rotating shaft 34. The hydraulic cylinder 351 and the slide rail 352 are respectively bolted to the vehicle body 1. The slider 353 is slidably connected to the slide rail 352. The slider 353 abuts against the output shaft of the hydraulic cylinder 351.

[0027] See attached Figure 1 and Figure 2 The dust removal mechanism 2 includes a water tank 21, a water pump 22, a water pipe 23, a nozzle 24 and a dust suction component. The dust suction component includes a dust collector 251 and a sedimentation box 252. The water tank 21 and the water pump 22 are both bolted to the vehicle body 1. The water pipe 23 is connected to the water tank 21 and the water pump 22. The nozzle 24 is connected to the water pipe 23. The nozzle 24 is tilted. The dust collector 251 is fixedly connected to the support frame 33. The sedimentation box 252 is bolted to the vehicle body 1. A plurality of air outlet holes 2521 are provided on the sedimentation box 252. A dust suction pipe 253 is connected to the dust collector 251 and the sedimentation box 252.

[0028] During the asphalt pavement maintenance process, the water pump 22 is first started to pump the water in the water tank 21 into the water pipe 23, and the water is discharged through the nozzle 24 so that the water is sprinkled on the ground and the milling cutter 31, which can reduce the probability of generating a large amount of dust during milling and then drifting into the air; then the first motor 32 is driven to drive the rotating shaft 34 to drive the milling cutter 31 to rotate on the support frame 33, and then the slider 353 is driven by the hydraulic cylinder 351 to slide on the slide rail 352, thereby driving the support frame 33 to drive the milling cutter 31 to slide on the vehicle body 1; when the milling cutter 31 needs to work, the hydraulic cylinder 351 drives the milling cutter 31 between the ground and the ground. The support is dropped with a constant distance, so that the support frame 33 drives the first motor 32, the rotating shaft 34 and the milling cutter 31 to slide downward, and the old road surface is excavated and renovated; when the nozzle 24 fails to completely wet the road surface, a small amount of dust may be generated. Under the action of the vacuum cleaner 251, a small amount of dust is sucked into the vacuum pipe 253, and then the dust enters the bottom of the sedimentation box. The internal pressure of the sedimentation box increases, and the gas is discharged from the air outlet 2521, further improving the dust removal effect; the gravel on the asphalt road surface is transported to the outlet end of the conveying mechanism 5 through the conveying mechanism 5, and then the cut material can be transported to the receiving vehicle for recovery.

[0030] When the milling operation is completed, the hydraulic cylinder 351 is used to drive the milling cutter 31 to move upward until it reaches the optimal cleaning position of the milling cutter 31, and then the second motor 41 is used to drive the lead screw 42 to rotate on the vehicle body 1, thereby driving the support block 43 to slide on the vehicle body 1, so that the cleaning brush 44 moves. During the movement of the cleaning brush 44, the asphalt material that is easily adhered to the surface of the milling cutter 31 is cleaned, thereby reducing the probability of sticky asphalt material being adsorbed on the surface of the milling cutter 31, thereby reducing the labor intensity of manual labor and improving the cleaning effect.

[0031] The implementation principle of the milling equipment for asphalt pavement maintenance of roads and bridges according to the embodiment of the utility model is as follows: during the asphalt pavement maintenance process, the water pump 22 is first started to pump the water in the water tank 21 into the water pipe 23, and the water is discharged through the nozzle 24 so that the water is sprinkled on the ground and the milling cutter 31, which can reduce the probability of generating a large amount of dust during milling and then drifting into the air; then the first motor 32 is driven to drive the rotating shaft 34 to drive the milling cutter 31 to rotate on the support frame 33, and then the slider 353 is driven by the hydraulic cylinder 351 to slide on the slide rail 352, thereby driving the support frame 33 to drive the milling cutter 31 to slide on the vehicle body 1; when the milling cutter 31 needs to work, the hydraulic cylinder 351 drives the distance between the milling cutter 31 and the ground to keep constant and drop the support, thereby causing the support frame 33 to drive the first motor 32, the rotating shaft 34 and the milling cutter 31 to slide downward, thereby excavating and renovating the old road surface; when the nozzle 24 fails to work, the hydraulic cylinder 351 drives the milling cutter 31 to keep a constant distance from the ground ... When the road surface is completely wet, a small amount of dust may be generated. Under the action of the vacuum cleaner 251, a small amount of dust is sucked into the vacuum pipe 253, and then the dust enters the bottom of the sedimentation box. The internal pressure of the sedimentation box increases, and the gas is discharged from the air outlet 2521, further improving the dust removal effect; the gravel on the asphalt road surface is transported to the outlet end of the conveying mechanism 5 through the conveying mechanism 5, and then the cut material can be transported to the receiving vehicle for recycling; when the milling operation is completed, the hydraulic cylinder 351 is driven, and the cylinder output shaft retracts, so that the milling cutter 31 moves upward until it reaches the optimal cleaning position of the milling cutter 31, and then, driven by the second motor 41, the lead screw 42 rotates on the vehicle body 1, thereby driving the support block 43 to slide on the vehicle body 1, so that the cleaning brush 44 moves, and during the movement of the cleaning brush 44, the asphalt material that is easily adhered to the surface of the milling cutter 31 is cleaned, thereby reducing the probability of sticky asphalt material adsorbed on the surface of the milling cutter 31.
