Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road construction technology, specifically a backfilling device for permafrost road construction in high-altitude areas. Background Technology
[0002] Road construction refers to the process of building, reconstructing or maintaining roads in accordance with planning and design and engineering technical standards. It mainly includes roadbed treatment, pavement paving, drainage system construction, traffic sign installation and other aspects. Construction often needs to take into account geological conditions, climate factors and environmental protection requirements.
[0003] When backfilling, it is necessary to drill holes at the backfill location in advance. However, because frozen soil is prone to clumping and contains unmelted frozen soil particles, the density is insufficient after direct backfilling and compaction. In the later freeze-thaw cycle, the road settlement and cracking will be further aggravated, thus affecting the backfilling effect and efficiency. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a backfilling device for permafrost road construction in high-altitude areas. It solves the problem that due to the tendency of permafrost soil to clump and the presence of unmelted permafrost particles, the density is insufficient after direct backfilling and compaction. Furthermore, subsequent freeze-thaw cycles of permafrost will further aggravate road settlement and cracking, thus affecting the backfilling effect and efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a backfilling device for permafrost road construction in high-altitude areas, comprising a load-bearing fork seat, a caster wheel installed on one side below the load-bearing fork seat, a support leg connected to the other side below the load-bearing fork seat, a handle connected to one side above the load-bearing fork seat, a column connected to the load-bearing fork seat, a hydraulic push rod fixedly installed on the top of the column, a fixing hoop connected to the column, a material cylinder fixedly installed on the column through the fixing hoop, and a movable platform slidably installed on the column; A working motor is fixedly installed above the moving platform. The output shaft of the working motor is connected to a connecting rod. One end of the connecting rod is connected to a drill bit. A spiral auger is connected to the drill bit. A material inlet is opened inside the material cylinder. A protective cover is connected above the material cylinder. A gear ring is rotatably connected to the material cylinder through a rotary bearing. A heat-conducting cylinder is connected to the gear ring. Multiple stirring plates are connected to the inner wall of the heat-conducting cylinder.
[0006] As a further embodiment of this utility model: a rotating rod is rotatably connected to one side of the protective cover via a bearing, and a gear is connected to one end of the rotating rod. The gear ring and the gear mesh with each other and are both disposed inside the protective cover.
[0007] As a further embodiment of this utility model: a cavity is provided between the inner wall and the outer wall of the material cylinder, and multiple electric heating tubes are installed in the cavity, and the heat-conducting cylinder is in contact with the inner wall of the material cylinder.
[0008] As a further embodiment of this utility model: a drive motor is fixedly installed on the fixing hoop, the output shaft of the drive motor is connected to the rotating rod, and the connecting rod is rotatably connected to the movable table through a bearing.
[0009] As a further embodiment of this utility model: both the drill bit and the auger are located at the feed inlet, and the multiple stirring plates inside the heat-conducting cylinder are arranged in an alternating vertical arrangement.
[0010] As a further embodiment of this utility model: a connecting groove is provided on the movable platform, the connecting groove is T-shaped and slidably connected to the column, and the movable end of the hydraulic push rod is connected to the movable platform.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This backfilling device for permafrost road construction in high-altitude areas is equipped with an electric heating tube, gears, a gear ring, a heat-conducting cylinder, and a mixing plate. After the soil is transported to the material cylinder by a drill bit and a spiral auger, or directly filled into the material cylinder, the drive motor is started to rotate the rotating rod, which causes the gear to rotate. The meshing of the gear and the gear ring causes the gear ring to drive the heat-conducting cylinder to rotate inside the material cylinder. At the same time, the electric heating tube heats the inner wall of the material cylinder, which in turn transfers heat to the heat-conducting cylinder to heat the soil. The rotating heat-conducting cylinder simultaneously drives the mixing plate to stir the soil, thereby stirring the loose soil and promoting uniform heating, thus improving the soil backfilling effect.
[0012] 2. This backfilling device for permafrost road construction in high-altitude areas is equipped with a hydraulic push rod, a movable platform, a connecting rod, a drill bit, and a spiral auger. By starting the working motor and rotating the connecting rod, the drill bit can rotate inside the material cylinder. By starting the hydraulic push rod, the movable platform is moved down, causing the drill bit to drill into the permafrost. The spiral auger then transports the damaged permafrost to the material cylinder for heating and breaking it up, which then becomes the backfill material. By raising the movable platform and reversing the drill bit, the spiral auger can use the broken up material to backfill through the material inlet, thus improving efficiency.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0015] like Figure 1-4 As shown, this utility model provides a technical solution: a backfilling device for permafrost road construction in high-altitude areas, including a load-bearing fork seat 1, a universal wheel 2 installed on one side below the load-bearing fork seat 1, a support leg 3 connected to the other side below the load-bearing fork seat 1, a handle 4 connected to one side above the load-bearing fork seat 1, a column 5 connected to the load-bearing fork seat 1, a hydraulic push rod 6 fixedly installed on the column 5, a fixing hoop 7 connected to the column 5, a drive motor 22 fixedly installed on the fixing hoop 7, the output shaft of the drive motor 22 connected to the rotating rod 19, and the connecting rod 11 rotatably connected to the movable platform 9 through a bearing. By rotating the rotating rod 19 through the drive motor 22, the gear 20 is rotated, and then the meshing of the gear 20 and the gear ring 16 drives the heat-conducting cylinder 17 to rotate, causing the mixing plate 18 to stir and disperse the soil material, thereby improving the heating and backfilling effect.
[0016] The column 5 is fixedly installed with the material cylinder 8 by the fixing hoop 7. There is a cavity between the inner wall and the outer wall of the material cylinder 8 and multiple electric heating tubes 21 are installed in the cavity. The heat conduction cylinder 17 is in contact with the inner wall of the material cylinder 8. The heat conduction cylinder 17 absorbs the heat generated by the electric heating tubes 21, thereby heating the soil in the material cylinder 8, so as to avoid the soil containing unmelted frozen soil particles from affecting the backfilling effect.
[0017] A movable platform 9 is slidably installed on the column 5. The movable platform 9 has a connecting groove 23. The connecting groove 23 is T-shaped and slidably connected to the column 5. The movable end of the hydraulic push rod 6 is connected to the movable platform 9. Through the sliding cooperation between the T-shaped connecting groove 23 and the column 5, the sliding trajectory of the movable platform 9 can be restricted, ensuring that the movable platform 9 can be stably raised and lowered along the axis of the column 5 and avoiding tilting.
[0018] A working motor 10 is fixedly installed above the working platform 9. The output shaft of the working motor 10 is connected to a connecting rod 11. One end of the connecting rod 11 is connected to a drill bit 12. A spiral auger 13 is connected to the drill bit 12. Both the drill bit 12 and the spiral auger 13 are located at the material inlet 14. Multiple stirring plates 18 inside the heat conduction cylinder 17 are arranged in an alternating pattern. The soil is stirred by the multiple alternating stirring plates 18, thereby improving the heating uniformity of the soil. The spiral auger 13 facilitates the transportation and backfilling of the soil, improving the backfilling efficiency.
[0019] A feed inlet 14 is provided inside the feed cylinder 8. A protective cover 15 is connected to the top of the feed cylinder 8. A rotating rod 19 is rotatably connected to one side of the protective cover 15 via a bearing. A gear 20 is connected to one end of the rotating rod 19. A gear ring 16 meshes with the gear 20 and is located inside the protective cover 15. A gear ring 16 is rotatably connected to the feed cylinder 8 via a slewing bearing. A heat-conducting cylinder 17 is connected to the gear ring 16. Multiple stirring plates 18 are connected to the inner wall of the heat-conducting cylinder 17. The protective cover 15 protects the gear ring 16 and the gear 20 to prevent soil particles from bumping and damaging the gear ring 16 and the gear 20.
[0020] The working principle of this utility model is as follows: By starting the working motor 10 and rotating the connecting rod 11, the drill bit 12 rotates inside the material cylinder 8. Then, the hydraulic push rod 6 is started to push the movable platform 9 down, causing the drill bit 12 to drill into the frozen soil. The auger 13 is then used to transport the damaged frozen soil into the material cylinder 8. During the process, the drive motor 22 is started to drive the rotating rod 19 to rotate the gear 20. The meshing of the gear 20 and the gear ring 16 causes the gear ring 16 to drive the heat-conducting cylinder 17 to rotate inside the material cylinder 8. At the same time, the electric heating tube 21 can heat the inner wall of the material cylinder 8, thereby transferring heat to the heat-conducting cylinder 17 to heat the soil. The rotating heat-conducting cylinder 17 simultaneously drives the mixing plate 18 to stir the soil, thereby stirring the loose soil and promoting uniform heating. Finally, by raising the movable platform 9 and reversing the drill bit 12, the auger 13 can be used to backfill the broken soil through the material inlet 14.
