Description

Technical Field

[0001] This utility model belongs to the field of highway engineering technology, and more specifically, it relates to a roadbed and pavement compaction device. Background Technology

[0002] Subgrade and pavement compaction refers to the compaction of the subgrade and pavement using mechanical or manual methods to improve their density and strength. Specifically, compaction involves applying external force to expel air from the soil or mixture, causing particles to rearrange and thus increasing the density and strength of the soil or mixture. Subgrade compaction is crucial to ensure the subgrade has sufficient bearing capacity and stability. Subgrade construction disrupts the natural state of the soil, resulting in a loose structure and requiring particle rearrangement. To ensure sufficient strength and stability, compaction is necessary to increase its density. Therefore, subgrade compaction is a vital step in subgrade construction and one of the fundamental technical measures to improve subgrade strength and stability. However, some existing subgrade and pavement compaction devices are difficult to move, some have poor compaction effects, and some cannot level the compacted pavement, resulting in an uneven surface after compaction. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a roadbed and pavement compaction device to solve the issues of inconvenient movement, poor compaction effect, and uneven pavement after compaction associated with existing devices.

[0004] This utility model discloses a roadbed and pavement compaction device, which is achieved through the following specific technical means:

[0005] A roadbed and pavement compaction device includes: a support frame; a device housing connected to the top of the support frame; an opening on the upper side of the device housing with an internal mounting plate; threaded holes at the four corners of the mounting plate; a top plate on the top of the device housing; mounting bolts at the four corners of the top plate, passing through the threaded holes on the mounting plate from top to bottom; force-applying rods connected to the left and right sides of the device housing; a support platform in the middle of the inner wall of the device housing; a compaction block inside the inner cavity of the device housing; a support plate above the compaction block; vibration motors at the four corners of the support plate, fixed to the support platform; support blocks on the front, back, left, and right sides of the support plate; and telescopic rods below the support blocks, with their lower ends fixed to the support platform.

[0006] Furthermore, a set of compaction rollers is provided on both the left and right sides of the support frame, with the middle of the compaction rollers passing through the support shaft and the two ends of the support shaft fixed to the support frame.

[0007] Furthermore, a hydraulic rod is provided at the middle position of the lower side of the top plate of the device, and a lifting hook is provided at the lower end of the hydraulic rod.

[0008] Furthermore, a lifting ring is provided at the middle position of the side surface of the support plate.

[0009] Furthermore, an operation window is provided on the upper left side of the device housing.

[0010] Furthermore, the bottom surface of the compacted block is provided with a cross-shaped protrusion.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by setting a compaction roller, roughly levels the road surface before the device compacts the roadbed and road surface, preventing unevenness of the compacted roadbed and road surface from affecting subsequent construction.

[0013] 2. This utility model, by setting up a hydraulic rod, a lifting hook, a lifting ring, and an operating window, allows the hydraulic rod to be extended and the lifting hook to be lowered when the device needs to be moved. The lifting hook is then hung on the lifting ring through the operating window, and the hydraulic rod is retracted to lift the compacted block. The device is then moved by rolling the compaction roller.

[0014] 3. This utility model enhances the compaction effect of the compaction block on the roadbed and pavement by setting a cross-shaped protruding block and increasing the pressure by reducing the contact area. Attached Figure Description

[0037] As attached Figure 1 To be continued Figure 5 As shown:

[0038] This utility model provides a roadbed and pavement compaction device, including: a support frame 1; a device housing 4 connected to the upper part of the support frame 1, the upper side of the device housing 4 having an opening with an internal mounting plate 403, threaded holes 402 at the four corners of the mounting plate 403, a device top plate 5 on the upper part of the device housing 4, mounting bolts 501 at the four corners of the device top plate 5, the mounting bolts 501 passing through the device top plate 5 from top to bottom and connecting to the threaded holes 402 on the mounting plate 403, force rods 6 connected to the left and right sides of the device housing 4, a support platform 13 in the middle of the inner wall of the device housing 4, a compaction block 7 in the inner cavity of the device housing 4, a support plate 9 on the upper part of the compaction block 7, a vibration motor 10 at the four corners of the support plate 9, the vibration motor 10 fixed on the support platform 13, support blocks 901 on the front, back, left, and right sides of the support plate 9, and a telescopic rod 11 below each support block 901, the lower end of the telescopic rod 11 fixed on the support platform 13.

[0039] Among them, such as Figure 2 As shown, a set of compaction rollers 3 are provided on both the left and right sides of the support frame 1. The compaction rollers 3 pass through the support shaft 2 in the middle. The two ends of the support shaft 2 are fixed on the support frame 1. Before the device compacts the roadbed and pavement, the pavement is roughly leveled to prevent unevenness of the compacted roadbed and pavement from affecting subsequent construction.

[0040] Among them, such as Figure 3 , Figure 4 and Figure 5 As shown, a hydraulic rod 14 is located in the middle of the lower side of the top plate 5 of the device, and a lifting hook 1401 is located at the lower end of the hydraulic rod 14. A lifting ring 12 is located in the middle of the upper side of the support plate 9. An operating window 401 is located on the upper left side of the outer casing 4 of the device. When the device needs to be moved, the hydraulic rod 14 is extended and the lifting hook 1401 is lowered. The lifting hook 1401 is hung on the lifting ring 12 through the operating window 401. The hydraulic rod 14 is retracted and the compacted block is lifted. The device is moved by rolling the compaction roller 3.

[0041] Among them, such as Figure 2 As shown, the bottom surface of the compaction block 7 is provided with a cross-shaped protrusion 8, which enhances the compaction effect of the compaction block 7 on the roadbed and pavement by reducing the contact area and increasing the pressure.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In this invention, the device is moved to the road surface that needs to be compacted, the hydraulic rod 14 is extended and the compaction block 7 is lowered. The lifting hook 1401 hanging on the lifting ring 12 is removed through the operation window 401, the compaction block 7 lands, the vibration motor 10 is turned on, and the force application rod 6 is pushed to move the device to compact the roadbed and road surface. After the road surface and roadbed are compacted, when the device needs to be moved, the hydraulic rod 14 is extended and the lifting hook 1401 is lowered. The lifting hook 1401 is hung on the lifting ring 12 through the operation window 401, the hydraulic rod 14 is retracted and the compaction block 7 is lifted.
