Description

Technical Field

[0001] This invention belongs to the field of highway subgrade construction technology, specifically a highway subgrade compaction machine. Background Technology

[0002] A compaction machine is an important piece of engineering machinery widely used in infrastructure construction such as roads, municipal engineering, airport runways, and ports. Its main function is to compact the laid materials using its own weight and vibration devices to achieve the required density, thereby enhancing the material's load-bearing capacity and stability.

[0003] In actual use, the steel wheels of the compactor will rust when they are in contact with rainwater for a long time. This is especially true when the construction site is poorly equipped and lacks rain protection facilities. The moisture and impurities in the rainwater will adhere to the surface of the steel wheel, which will easily cause the steel wheel to rust. This will affect the service life and working efficiency of the compactor. This rust problem will not only increase the maintenance cost of the equipment, but may also affect the compaction effect and cause the roadbed surface to be uneven.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a roadbed compaction machine for highway subgrade construction. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a roadbed compaction machine to solve the problem that in the prior art, the steel wheels of compaction machines corrode when exposed to rainwater for extended periods. This is especially problematic in situations where construction sites are poorly equipped and lack rain protection facilities. In such cases, moisture and impurities in the rainwater adhere to the surface of the steel wheels, easily causing them to rust. This, in turn, affects the service life and working efficiency of the compaction machine, increasing maintenance costs and potentially impacting compaction effectiveness, leading to uneven roadbed surfaces.

[0006] A roadbed compaction machine includes a support frame, steel wheels mounted on the support frame, support plates connected to the support frame, a first unfolding assembly, a second unfolding assembly, a third unfolding assembly and an adjustment assembly connected to two support plates, the adjustment assembly being connected to the first unfolding assembly, support rods being connected to the first unfolding assembly, the second unfolding assembly and the third unfolding assembly respectively, and tarpaulins being connected to a plurality of the support rods.

[0007] Preferably, the first unfolding component includes a first fan blade rotatably connected to the support plate, the first fan blade having a first sliding groove, and a first limiting plate and a first baffle respectively connected to both ends of the first sliding groove.

[0008] Preferably, the second unfolding component includes a second fan blade rotatably connected to the support plate, the second fan blade having a second sliding groove, the two ends of the second sliding groove being respectively connected to a second limiting plate and a second baffle, and a first slider being fixedly installed at the end of the second fan blade connected to the second limiting plate.

[0009] Preferably, the first slider slides into the first groove, and the first and second fan blades are misaligned.

[0010] Preferably, the third unfolding component includes a third fan blade fixedly connected to the support plate, and the third fan blade is fixedly mounted with a second slider.

[0011] Preferably, the second slider slides into the second groove, the first and second fan blades are offset from one another, the rotation centers of the first, second and third fan blades overlap, and the first, second and third fan blades are fixedly connected to the support rod.

[0012] Preferably, the adjustment assembly includes a mounting plate fixedly connected to a support plate, a hydraulic cylinder fixedly mounted on the upper surface of the mounting plate, a synchronization plate fixedly connected to the hydraulic cylinder, a rack fixedly connected to the synchronization plate, a gear meshing with the rack, a synchronization rod fixedly connected to the gear, and a synchronization arm fixedly connected to the synchronization rod.

[0013] Preferably, the synchronizing arm is an "L"-shaped plate, one end of the synchronizing arm is fixedly connected to the first fan blade, and the other end of the synchronizing arm is fixedly connected to the synchronizing rod.

[0014] Preferably, the adjustment assembly further includes a slide rail fixedly connected to the mounting plate, the slide rail slidingly engaging with the rack, the mounting plate being fixedly connected to a base plate, and the two base plates being rotatably connected to a synchronizing rod.

[0015] Preferably, the bracket is fixedly mounted with an electric telescopic rod, the electric telescopic rod is fixedly connected to an assembly plate, the assembly plate is fixedly connected to a fitting scraper, and the shape of the fitting scraper is adapted to the steel wheel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention provides power by adjusting the components, enabling the first, second, and third deployment components to work together to quickly and smoothly deploy the tarpaulin. The deployed tarpaulin is laid on top of the steel wheels, forming an effective protective barrier. This prevents rainwater from directly contacting the steel wheels, effectively preventing moisture and impurities in the rainwater from corroding the steel wheels. It also significantly reduces damage to the steel wheels caused by rust, extends the service life of the steel wheels, provides reliable protection for the steel wheels in harsh construction environments, and reduces maintenance costs and equipment replacement frequency.

[0018] 2. This invention uses mechanical transmission through adjusting components to drive the first fan blade to rotate. During the rotation of the first fan blade, the first baffle and the first slider work together to achieve coordinated movement, which drives the second fan blade to rotate along with the first fan blade. Ultimately, the first, second, and third fan blades can work together to complete the unfolding or closing action, making the unfolding and retraction of the tarpaulin faster and more efficient, greatly saving preparation and adjustment time. By optimizing the unfolding and retraction of the tarpaulin, the convenience of using the equipment is improved.

[0019] 3. This invention, through precise control of the electric telescopic rod, enables the assembly plate to move flexibly. The movement of the assembly plate allows the fitting scraper to precisely adhere to the surface of the steel wheel. During the rolling of the steel wheel, the fitting scraper effectively cleans the sand and dirt around the steel wheel, not only avoiding the adverse effects of sand and dirt on the compaction effect, but also preventing these impurities from wearing and damaging the surface of the steel wheel. In this way, this invention ensures compaction quality while protecting the surface of the steel wheel, extending the service life of the steel wheel, and further improving the reliability of the equipment and the construction quality.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Example 1

[0030] As attached Figure 1 As shown, this invention provides a roadbed compaction machine, including a support 1, which is a part at the front end of the compaction machine. A steel wheel 2 is mounted on the compaction machine via the support 1. During operation, the steel wheel 2 compacts the material. The support 1 is connected to support plates 3, with two support plates 3 located on either side of the steel wheel 2. The two support plates 3 are connected to a first unfolding assembly 4, a second unfolding assembly 5, a third unfolding assembly 6, and an adjusting assembly 7. The adjusting assembly 7 provides power to control the unfolding or closing of the first unfolding assembly 4, the second unfolding assembly 5, and the third unfolding assembly 6. The first unfolding assembly 4, the second unfolding assembly 5, and the third unfolding assembly 6 work together to quickly and smoothly unfold the tarpaulin 9. The second unfolding component 5 can be set in multiple sets as needed. The adjusting component 7 is connected to the first unfolding component 4. The first unfolding component 4, the second unfolding component 5, and the third unfolding component 6 are each connected to a support rod 8. The support rod 8 provides support for the tarpaulin 9 to ensure the unfolding effect of the tarpaulin 9. Several support rods 8 are connected to the tarpaulin 9. The first unfolding component 4, the second unfolding component 5, and the third unfolding component 6 work together to unfold the tarpaulin 9. The unfolded tarpaulin 9 is laid on top of the steel wheel 2, forming an effective protective barrier, thereby preventing rainwater from directly contacting the steel wheel 2. This not only effectively prevents the water and impurities in the rainwater from corroding the steel wheel 2, but also significantly reduces the damage to the steel wheel 2 caused by rust, and extends the service life of the steel wheel 2.

[0031] As can be seen from the above, when encountering rainy weather, the adjustment component 7 is activated to provide power. The adjustment component 7 drives the first unfolding component 4 to rotate. During the rotation of the first unfolding component 4, the second unfolding component 5 will also rotate. When the first unfolding component 4 and the second unfolding component 5 rotate to their maximum angle, the first unfolding component 4, the second unfolding component 5 and the third unfolding component 6 work together to quickly and smoothly unfold the tarpaulin 9 through the support rod 8. The unfolded tarpaulin 9 is laid on top of the steel wheel 2, forming an effective protective barrier to shield the steel wheel 2. This effectively prevents water and impurities in the rainwater from corroding the steel wheel 2, significantly reduces damage to the steel wheel 2 caused by rust, extends the service life of the steel wheel 2, provides reliable protection for the steel wheel 2 in harsh construction environments, and reduces maintenance costs and equipment replacement frequency.

[0032] Example 2

[0033] As attached Figure 1 To be continued Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the first unfolding component 4 includes a first fan blade 401 that is rotatably connected to the support plate 3. When the adjustment component 7 is working, it will drive the first fan blade 401 to rotate. The first fan blade 401 has a first sliding groove 402. The first sliding groove 402 rotates synchronously with the first fan blade 401. The two ends of the first sliding groove 402 are respectively connected to a first limiting plate 403 and a first baffle 404. The first limiting plate 403 and the first baffle 404 limit the maximum stroke of the first slider 505.

[0034] Specifically, the second unfolding component 5 includes a second fan blade 501 rotatably connected to the support plate 3. The second fan blade 501 has a second sliding groove 502. The two ends of the second sliding groove 502 are respectively connected to a second limiting plate 503 and a second baffle 504. During the rotation of the second fan blade 501, the second limiting plate 503 and the second baffle 504 limit the maximum stroke of the second slider 602. A first slider 505 is fixedly installed at one end of the second fan blade 501 connected to the second limiting plate 503. As the first fan blade 401 rotates forward and backward, the first slider 505 cooperates with the first limiting plate 403 or the first baffle 404 to make the first fan blade 401 drive the second fan blade 501 to rotate synchronously.

[0035] Furthermore, the first slider 505 slides in conjunction with the first slide groove 402, and the first slider 505 assists the first slide groove 402 in sliding, while the first fan blade 401 and the second fan blade 501 are misaligned.

[0036] Furthermore, the third unfolding component 6 includes a third fan blade 601 fixedly connected to the support plate 3. The third fan blade 601 is fixedly mounted with a second slider 602. During the rotation of the first fan blade 401, the first baffle 404 and the first slider 505 cooperate to achieve coordinated movement, which will drive the second fan blade 501 to rotate together with the first fan blade 401. Finally, the first fan blade 401, the second fan blade 501 and the third fan blade 601 can work together to complete the unfolding or closing action, making the unfolding and retraction process of the tarpaulin 9 faster and more efficient, greatly saving preparation time and adjustment time.

[0037] Furthermore, the second slider 602 slides into the second groove 502, the first blade 401 and the second blade 501 are misaligned, and the first blade 401, the second blade 501 and the third blade 601 will not conflict with each other and cause obstruction during rotation. The rotation centers of the first blade 401, the second blade 501 and the third blade 601 overlap, and the first blade 401, the second blade 501 and the third blade 601 are fixedly connected to the support rod 8 respectively.

[0038] As can be seen from the above, when encountering rainy weather, the adjustment component 7 is activated, which drives the first fan blade 401 to rotate. The first fan blade 401 rotates, and at this time, the first slide groove 402 slides along the first slider 505. As the first fan blade 401 rotates, the first baffle 404 comes into contact with the first slider 505. The first fan blade 401 continues to rotate, and the first baffle 404 drives the first slider 505 to rotate, thus causing the first fan blade 401 to rotate along with the second fan blade 501 until the second fan blade 501... The second baffle 504 abuts against the second slider 602. At this time, the first fan blade 401, the second fan blade 501 and the third fan blade 601 are fully extended. During the extension of the first fan blade 401, the second fan blade 501 and the third fan blade 601, the support rod 8 is driven to unfold the tarpaulin 9. The unfolded tarpaulin 9 provides cover for the steel wheel 2. When the adjustment component 7 works in reverse, it will drive the first fan blade 401 to rotate in the opposite direction. Then the first fan blade 401, the second fan blade 501 and the third fan blade 601 overlap and retract the tarpaulin.

[0039] Example 3

[0040] As attached Figure 5 To be continued Figure 6As shown, this embodiment is basically the same as the previous embodiment, except that the adjustment component 7 includes a mounting plate 701 fixedly connected to the support plate 3. The mounting plate 701 is used to provide support and installation space for the installation of other parts. A hydraulic cylinder 702 is fixedly installed on the upper surface of the mounting plate 701. The hydraulic cylinder 702 is fixedly connected to a synchronization plate 703. The extension and retraction of the hydraulic cylinder 702 will drive the synchronization plate 703 to move. The synchronization plate 703 is fixedly connected to a rack 704. The hydraulic cylinder 702 moves the rack 704 through the synchronization plate 703. The rack 704 meshes with a gear 705. During the movement of the rack 704, it will drive the gear 705 to rotate. The gear 705 is fixedly connected to a synchronization rod 706. The synchronization rod 706 is fixedly connected to a synchronization arm 707. During the rotation of the gear 705, the synchronization arm 707 rotates through the synchronization rod 706.

[0041] Specifically, the synchronizing arm 707 is an "L"-shaped plate. One end of the synchronizing arm 707 is fixedly connected to the first fan blade 401, and the other end of the synchronizing arm 707 is fixedly connected to the synchronizing rod 706. During the rotation of the synchronizing arm 707, it will rotate together with the first fan blade 401.

[0042] Furthermore, the adjustment assembly 7 also includes a slide rail 708 fixedly connected to the mounting plate 701. The slide rail 708 is slidably engaged with the rack 704. The slide rail 708 assists the rack 704 to move stably. The mounting plate 701 is fixedly connected to a base plate 709. The two base plates 709 are rotatably connected to the synchronizing rod 706, and the two base plates 709 provide support for the synchronizing rod 706.

[0043] Furthermore, the bracket 1 is fixedly equipped with an electric telescopic rod 10, which is fixedly connected to an assembly plate 11. The assembly plate 11 is fixedly connected to a bonding scraper 12. The precise extension and retraction of the electric telescopic rod 10 can drive the assembly plate 11 to move flexibly. The movement of the assembly plate 11 allows the bonding scraper 12 to accurately adhere to the surface of the steel wheel 2. The shape of the bonding scraper 12 is adapted to the steel wheel 2. During the rolling process of the steel wheel 2, the bonding scraper 12 can effectively clean the sand and soil around the steel wheel 2, avoiding the impact of sand and soil on the compaction effect. While ensuring the compaction quality, it also protects the surface of the steel wheel 2 and extends the service life of the steel wheel 2.

[0044] As can be seen from the above, when the hydraulic cylinder 702 is started, the hydraulic cylinder 702 drives the synchronous plate 703 to move. The hydraulic cylinder 702 drives the rack 704 to slide along the slide rail 708 through the synchronous plate 703. During the sliding of the rack 704, the gear 705 is driven to rotate. The rotating gear 705 drives the synchronous rod 706 and the synchronous arm 707 to rotate. In turn, the synchronous arm 707 drives the first fan blade 401 to rotate, thereby enabling the first fan blade 401, the second fan blade 501 and the third fan blade 601 to complete the opening or closing action.

[0045] During the compaction process, the steel wheel 2 will be covered with sand and soil. After the compaction is completed, the electric telescopic rod 10 is activated. The electric telescopic rod 10 moves the assembly plate 11, causing the contact scraper 12 to move and contact the steel wheel 2. During the rolling of the steel wheel 2, the contact scraper 12 will clean the sand and soil around the steel wheel 2, so as to avoid affecting the compaction effect or damaging the surface of the steel wheel 2.
