Description

Technical Field

[0001] This utility model relates to the field of engineering equipment technology, specifically a roadbed construction leveling equipment. Background Technology

[0002] The road base course is the main load-bearing layer of the road, paved with high-quality materials. The road base is the main factor that determines the quality of the entire road project and affects its service life. The higher the quality of the base course, the more firmly the road surface is laid.

[0003] Current roadbed leveling equipment, as described in patent CN210856865U, consists of a base plate with a leveling mechanism welded to its front, limit blocks welded to both sides of the base plate, a first bearing welded to the bottom of each limit block, a steering wheel fitted onto the inner wall of the first bearing, and connecting parts welded to both sides of the base plate. This invention, by incorporating a base plate, leveling mechanism, limit blocks, first bearing, steering wheel, connecting parts, second bearing, roller, connecting rod, and handrail, solves the problems of low efficiency and poor leveling effect of manual leveling. This roadbed leveling device for highway construction has the advantages of high leveling efficiency and good leveling effect. During use, the leveling plate at the bottom can level large areas of lime-soil, thereby improving the efficiency of lime-soil leveling. Compared to manual leveling, the leveling is more uniform, thus improving the leveling effect.

[0004] Regarding the aforementioned technologies, the inventors believe that when the manual pushing device is used for leveling operations, if the weight of the roller is insufficient, it is easy to cause incomplete leveling; while if the weight of the pressure roller is too heavy, it is not easy to push the device manually to perform the leveling work. Moreover, during the use of the roller, materials on the road surface are easy to stick to the roller. When materials stick to the roller, it will damage the flatness of the compacted road surface and reduce the flatness of the road surface. Utility Model Content

[0005] The purpose of this invention is to provide a roadbed construction leveling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A roadbed leveling device includes a vehicle body. Two spaced-apart mounting blocks are fixedly connected to one side of the bottom of the vehicle body. A rotating shaft is rotatably connected between the two mounting blocks. Wheels are fixedly connected to both ends of the rotating shaft. A drive assembly connected to the rotating shaft is provided on the top of the vehicle body. A handrail with a switch is provided on the handrail. A square frame is fixedly connected to one side of the vehicle body. A compaction roller is rotatably connected inside the square frame. Through grooves are provided on both sides of the square frame. Scrapers adapted to the compaction roller are movably arranged in the through grooves. Fixed screws are passed through both ends of the scrapers. A first threaded hole adapted to the fixed screws is provided on the square frame.

[0008] As a further embodiment of this utility model: the drive assembly includes a drive motor fixedly connected to the top of the vehicle body, the drive motor being electrically connected to a switch via a wire, the output end of the drive motor being connected to a first transmission wheel, a second transmission wheel fixedly connected to the rotating shaft and located directly below the first transmission wheel, a transmission belt being sleeved between the first transmission wheel and the second transmission wheel, and a through hole corresponding to the transmission belt being provided on the vehicle body.

[0011] As a further embodiment of this utility model, the top of the scraper is provided with a guide slope.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] With the above-described structure, this invention utilizes a rotating shaft, wheels, a drive assembly, a switch, a roller, a scraper, a fixing screw, and a first threaded hole. The switch activates the drive motor within the drive assembly, which in turn drives the wheels to rotate, propelling the roller forward to level the road surface. This eliminates the need for manual pushing, improving road leveling efficiency. The scraper on the front of the roller removes any material adhering to it, preventing it from affecting the smoothness of the leveled road surface. The fixing screw and the first threaded hole facilitate the disassembly and replacement of the scraper, preventing wear and tear after prolonged use and ensuring effective scraping.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] Please see Figure 1-4 A roadbed construction leveling device includes a vehicle body 1. The vehicle body 1 has two spaced mounting blocks 2 fixedly connected to one side of its bottom. A rotating shaft 3 is rotatably connected between the two mounting blocks 2. Wheels 4 are fixedly connected to both ends of the rotating shaft 3. A drive assembly 5 connected to the rotating shaft 3 is provided on the top of the vehicle body 1, which can drive the rotating shaft 3 and the wheels 4 to rotate, facilitating the leveling work, saving manpower, and improving leveling efficiency. The top of the vehicle body 1 is provided with a handrail 6, and a switch 7 is provided on the handrail 6 for controlling the operation of the drive component 5. A square frame 8 is fixedly connected to one side of the vehicle body 1. A rolling roller 9 is rotatably connected inside the square frame 8 for leveling. Through grooves 10 are opened on both sides of the square frame 8. A scraper 11 adapted to the rolling roller 9 is movably arranged in the through grooves 10. The scraper 11 is positioned on one side of the rolling roller 9 in the forward direction. In this way, when the material scraped off by the rolling roller 9 falls to the ground, it can be rolled and leveled again by the rolling roller 9. Fixing screws 12 are passed through both ends of the scraper 11. A first threaded hole 13 adapted to the fixing screws 12 is opened on the square frame 8. The cooperation between the fixing screws 12 and the first threaded hole 13 facilitates the disassembly and assembly of the scraper 11, making it easy to replace the scraper 11 after it wears out after long-term use.

[0022] Furthermore, the drive assembly 5 includes a drive motor 501 fixedly connected to the top of the vehicle body 1. The drive motor 501 is electrically connected to the switch 7 via wires. The output end of the drive motor 501 is connected to a first transmission wheel 502. A second transmission wheel 503 located directly below the first transmission wheel 502 is fixedly connected to the rotating shaft 3. A transmission belt 504 is sleeved between the first transmission wheel 502 and the second transmission wheel 503. The vehicle body 1 has through holes corresponding to the transmission belt 504. When in use, the drive assembly 5 can be activated by the switch 7 on the armrest 6, thereby driving the first transmission wheel 502 to rotate. With the cooperation of the transmission belt 504, the second transmission wheel 503 will rotate synchronously, thereby driving the rotating shaft 3 and the wheel 4 to rotate.

[0023] Furthermore, the wheel 4 is fixedly connected with several anti-slip protrusions 14 arranged in a circular array, which can increase the friction between the wheel 4 and the ground, thereby improving the grip of the wheel 4 and facilitating the rolling of the roller 9 for rolling and leveling work.

[0024] Furthermore, the square frame 8 is provided with a second threaded hole 15 that is adapted to the fixing screw 12. The position of the scraper 11 can be adjusted through the second threaded hole 15. When the distance between the scraper 11 and the rolling roller 9 is not appropriate, the scraper 11 can be aligned with the second threaded hole 15, and the fixing screw 12 can be inserted into the second threaded hole 15 to adjust the scraping distance between the scraper 11 and the rolling roller 9, thereby improving the flexibility of the scraping operation.

[0025] Furthermore, the top of the scraper 11 is provided with a guide slope 16. By providing the guide slope 16, the material scraped by the scraper 11 can fall along the guide slope 16 at the top of the scraper 11, so that it will not accumulate on the top of the scraper 11.

[0026] In use, the drive motor 501 can be started by the switch 7 on the handrail 6, which drives the first transmission wheel 502 to rotate. With the cooperation of the transmission belt 504, the second transmission wheel 503 will rotate synchronously, which will drive the rotating shaft 3 and the wheel 4 to rotate. When the wheel 4 rotates, it will push the roller 9 to roll forward and level the road surface. During the road leveling process, the material adhering to the roller 9 will be scraped off by the scraper 11 on the front side of the roller 9. The scraped material will fall on the road surface and be flattened by the roller 9.
