[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, a high-altitude frozen soil roadbed compaction device includes a roller frame 1, which includes a connecting frame 11 and a vertical frame 12. The vertical frame 12 is fixedly installed at both ends of the connecting frame 11, and a pressure roller 2 is installed at the lower end of the vertical frame 12. The pressure roller 2 is rotatably connected to the vertical frame 12. A protective cover 3 is arranged just above the pressure roller 2. The protective cover 3 is slidably sleeved on the vertical frame 12, and an electric cylinder 4 for driving the protective cover 3 to rise and fall is also fixedly installed on the vertical frame 12. A split nozzle 5 is fixedly installed on the inner side of the protective cover 3, and a hot air blower 6 for supplying air to the split nozzle 5 is also included. The structural setting of the roller frame 1 ensures that it is connected and fixed with the roller equipment through the connecting frame 11, and then the pressure roller 2 is installed through the two vertical frames 12, so that the pressure roller 2 can be stably pressed on the road surface during construction, and the setting of the protective cover 3 ensures that safety protection can be achieved during the rolling process to avoid splashing on the road surface, and the setting of the electric cylinder 4 ensures that the use height of the protective cover 3 can be flexibly adjusted during use. The vertical frame 12 includes a frame rod 121 and a shaft collar seat 122. The shaft collar seat 122 is arranged at the lower end of the frame rod 121, and the shaft collar seat 122 is integrally formed with the frame rod 121. The shaft collar seat 122 is arranged on the frame rod 121 by the structural arrangement of the vertical frame 12. When it is easy to use, the pressure roller 2 can be rotated and installed by the shaft collar seat 122. Moreover, the arrangement of the split nozzle 5 and the hot air blower 6 ensures that the frozen soil road surface can be auxiliary heated, which facilitates better roadbed compaction operation.

[0024] Reference Figure 1 and Figure 2 As shown, the protective cover 3 includes a heat insulation cover 31 and a sleeve 32, the sleeve 32 is fixedly mounted on both sides of the heat insulation cover 31, and the sleeve 32 is slidably mounted on the rack 121. The protective cover 3 is structurally arranged to ensure that the sleeve 32 is arranged on the heat insulation cover 31, and when it is easy to use, it can be sleeved on the rack 121 through the sleeve 32. The heat insulation cover 31 includes a protective outer shell 311 and a heat insulation inner pad 312, and the heat insulation inner pad 312 is glued and fixed to the inner side of the protective outer shell 311. The heat insulation cover 31 is structurally arranged to ensure that the heat insulation inner pad 312 is arranged on the inner side of the protective outer shell 311, and when it is easy to use, it can be used for heat insulation through the heat insulation inner pad 312, so as to ensure a better heating effect when heating the roadbed.

The structural setting of the diverter nozzle 5 ensures that the jet elbow 52 is set on both sides of the pipe box 51. When it is easy to use, the hot air blower 6 transports hot air from the air inlet pipe 511 to the pipe box 51, and then blows the roadbed in real time through the jet elbows 52 on both sides. A roller baffle 512 is installed on the lower end surface of the pipe box 51, and the roller baffle 512 is fixedly connected to the pipe box 51. The setting of the roller baffle 512 ensures that the surface of the pressure roller 2 is cleaned during the compaction process.

[0026] Working principle: When used on frozen soil roads at high altitudes, the equipment is installed on a mobile vehicle through a road compactor frame, and the mobile vehicle drives the equipment to perform compaction operations. At the same time, the electric cylinder is started to move the protective cover down to release the roller baffle from the roller surface, while ensuring that the diverter nozzle is closer to the ground. During the compaction process, if it is found that the roadbed cannot be compacted normally due to frozen soil, the hot air blower can be started to blow hot air from the diverter nozzle to the roadbed. When the roadbed thaws, compaction operations can be carried out normally.
