Description

Technical Field

[0001] The utility model relates to the technical field of road rolling devices, in particular to an asphalt pavement rolling device based on municipal road engineering. Background Technique

[0002] In municipal road engineering, compacting the asphalt pavement is one of the key construction links. As the core component of the road rolling device, the working performance and state of the compaction roller directly affect the compaction quality of the road surface. Under hot climate conditions or during long-term continuous operation, the surface temperature of the compaction roller will rise rapidly. When the high-temperature compaction roller comes into direct contact with the asphalt pavement, it is easy to cause premature aging, excessive softening or even burning of the asphalt material, which will damage the adhesion and stability of the asphalt, affect the durability and strength of the road surface, and the long-term high-temperature operation will cause wear and aging problems on the surface material of the compaction roller. At present, water cooling is mostly used for cooling, but there are many problems with water cooling. Water cooling causes serious waste of water resources, and a large amount of water is required for cooling at the construction site. In some areas with water shortages, this undoubtedly increases the construction cost and environmental pressure. Therefore, we introduce a new asphalt pavement rolling device based on municipal road engineering. Content of the Utility Model

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] 1. In the present utility model, during the compaction operation, the air cooler is turned on through the controller. The cold air generated by the air cooler is delivered to the air jet heads through the L-shaped air duct and the horizontal pipe, and then sprayed onto the outer surface of the compaction roller, facilitating the cooling treatment of the outer surface of the compaction roller.

[0029] An asphalt pavement rolling device based on municipal road engineering, including a rolling device main body 1. A fixing plate 2 is fixedly installed at the lower part of the front end of the rolling device main body 1. A fixing frame 3 is fixedly installed at the front end of the fixing plate 2.

Threaded holes 9 are arranged at the upper ends of the two fixing blocks 7. A compaction roller 10 is commonly movably installed between the inner left wall and the inner right wall of the fixing frame 3.

[0030] In this embodiment, the cooling device 4 includes a protective cover 40 and a cold air blower 41. An L-shaped air duct 42 is fixedly installed at the upper end of the cold air blower 41. A horizontal pipe 43 is fixedly installed at the front end of the L-shaped air duct 42. Eight air jet nozzles 44 are fixedly installed at the lower end of the horizontal pipe 43. A fixing shell 45 is fixedly installed at the upper part of the outer surface of the protective cover 40.

[0031] Through the above solution: when the air cooler 41 works, the generated cold air is conveyed to the jet head 44 through the L-shaped air duct 42 and the horizontal pipe 43, and then sprayed onto the outer surface of the compaction roller 10, which facilitates the cooling treatment of the outer surface of the compaction roller 10. The protective cover 40 can make the sprayed cold air form a relatively concentrated cooling area inside it, ensuring that the cold air can effectively cover the surface of the compaction roller 10 and improving the cooling efficiency.

[0032] In this embodiment, the scraping device 6 includes a mounting plate 60. A plurality of material discharge openings 61 are provided at the upper end of the mounting plate 60.

The protective cover 40 can make the sprayed cold air form a relatively concentrated cooling area inside it, ensuring that the cold air can effectively cover the surface of the compaction roller 10, improving the cooling efficiency, and avoiding problems such as wear and aging of the surface material of the compaction roller 10 caused by long-term high-temperature operation. When the scraper 62 is worn and needs to be disassembled after long-term use, by respectively removing the two fixing bolts 64 and making the two clamping blocks 63 disengage from the two clamping grooves 8, the mounting plate 60 and the scraper 62 can be taken out of the mounting groove 5, which is convenient for disassembly and replacement.
