Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a road roller for road joint surface construction. Background Technology

[0002] Currently, traditional road rollers have the following drawbacks when constructing road surface joints:

[0003] Single compaction effect: Conventional road rollers only use a single compaction method of smooth steel wheel or convex steel wheel, which cannot take into account the initial compaction density and final compaction texture requirements of the joint surface, and easily leads to insufficient interlayer bonding force.

[0004] Difficulty in maintaining the bumps: Most existing bump steel wheels are welded fixed bumps, which require the entire steel wheel to be replaced after wear, resulting in high costs and long downtime.

[0005] Low cleaning efficiency: Asphalt mixture adhering to the steel wheel during construction needs to be cleaned manually, especially the gaps between the bumps are easily blocked, affecting the uniformity of compaction. Summary of the Invention

[0006] This utility model aims to address the shortcomings of existing technologies by providing a road roller for road surface joint construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a road roller for road surface joint construction, comprising a double-drum roller body, a smooth steel wheel movably connected to the front side of the double-drum roller body, a protruding steel wheel movably connected to the rear side, and a plurality of protruding components detachably installed on the protruding steel wheel, and a scraper assembly corresponding to the smooth steel wheel detachably installed on the front frame of the double-drum roller body, and a height-adjustable wire brush cleaning assembly installed on the rear frame.

[0008] Specifically, the scraper assembly includes a pair of connecting seats bolted to the front and rear sides of the bottom of the frame, with an inclined scraper that contacts the surface of a smooth steel wheel fixed between the two connecting seats.

[0009] Specifically, the bump assembly includes several arc-shaped slide plates. Several grooves matching the slide plates are evenly distributed on the outer circumference of the bump steel wheel. The slide plates slide into the grooves. Several bumps are provided on the outer surface of the slide plates. Limiting plates for limiting the slide plates are fixed to the front and rear sides of the bump steel wheel by bolts.

[0010] Specifically, the wire brush cleaning assembly includes a motor housing, with several wire brush cleaning discs rotatably connected to the bottom of the motor housing. A motor that drives the wire brush cleaning discs to rotate is installed inside the motor housing. The bottom of the frame is provided with a groove, and the upper part of the motor housing is inserted into the groove. Electric cylinders that drive the motor housing to lift and lower are installed on the front and rear sides of the top of the groove.

[0011] The beneficial effects of this utility model are:

[0012] Dual-wheel synergistic compaction: The smooth steel wheel at the front achieves initial compaction of the joint surface, while the protruding steel wheel at the rear enhances the final compaction texture depth and improves the interlayer interlocking force.

[0013] Quick-change bump design: The detachable bump assembly allows for individual replacement of worn bumps, reducing maintenance costs; and the bump assembly achieves circumferential positioning through the interlocking of the slide plate and the slide groove, while the limit plate bolt fixing method allows for quick replacement of all bumps, significantly reducing downtime.

[0014] Modular cleaning system: The wire brush cleaning assembly is driven by an electric cylinder to lift and lower, and can dynamically adjust the clamping force between the wire brush and the bumps to adapt to different wear conditions; the rotary cleaning disc can reach deep into the gaps between the bumps to improve cleaning efficiency.

[0023] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] like Figure 1As shown, a road roller for road surface joint construction includes a double-drum roller body 1. A smooth steel drum 2 is movably connected to the front side of the double-drum roller body 1, and a protruding steel drum 3 is movably connected to the rear side. Several protruding components are detachably mounted on the protruding steel drum 3. A scraper assembly corresponding to the smooth steel drum 2 is detachably mounted on the front frame of the double-drum roller body 1, and a height-adjustable wire brush cleaning assembly is mounted on the rear frame. The front smooth steel drum 2 achieves initial compaction of the joint surface, while the rear protruding steel drum 3 enhances the final compaction texture depth and improves interlayer interlocking force.

[0026] like Figure 2 As shown, the scraper assembly includes a pair of connecting seats 4 bolted to the front and rear sides of the bottom of the frame, with an inclined scraper 5 fixed between the two connecting seats 4, which contacts the surface of the smooth steel wheel 2. The scraper assembly adopts an inclined design and makes full-width contact with the smooth steel wheel 2, effectively scraping off the adhering material; the split connecting seats facilitate quick disassembly and replacement.

[0027] like Figure 3 As shown, the wire brush cleaning assembly includes a motor housing 10, with several wire brush cleaning discs 11 rotatably connected to the bottom of the motor housing 10. A motor that drives the wire brush cleaning discs 11 to rotate is installed inside the motor housing 10. A groove 12 is provided at the bottom of the frame, and the upper part of the motor housing 10 is inserted into the groove 12. Electric cylinders 13 that drive the motor housing 10 to lift and lower are installed on the front and rear sides of the top of the groove 12. The wire brush cleaning assembly is driven to lift and lower by the electric cylinders 13, which can dynamically adjust the clamping force between the wire brush and the protrusions 7 to adapt to different wear conditions. The rotating cleaning discs can penetrate deep into the gaps between the protrusions 7, improving cleaning efficiency.

[0028] For example, 4- Figure 7 The figure shows that the protrusion assembly includes several arc-shaped sliding plates 6. Several grooves 9, matching the sliding plates 6, are evenly distributed around the outer surface of the protrusion steel wheel 3. The sliding plates 6 slide into the grooves 9, and several protrusions 7 are provided on the outer surface of the sliding plates 6. Limiting plates 8, which limit the movement of the sliding plates 6, are bolted to the front and rear sides of the protrusion steel wheel 3. The detachable protrusion assembly allows for individual replacement of worn protrusions 7, reducing maintenance costs. Furthermore, the protrusion assembly achieves circumferential positioning through the insertion and engagement of the sliding plates 6 and the grooves 9. The bolted fixing method of the limiting plates 8 allows for quick replacement of all protrusions 7, significantly reducing downtime.

[0029] Initial compaction stage: As the roller advances, the smooth steel wheel 2 at the front performs initial compaction on the road surface interface to ensure a dense and flat base layer. The scraper assembly is in close contact with the surface of the smooth steel wheel 2, automatically scraping off any adhering asphalt mixture to prevent material accumulation from affecting the compaction effect.

[0030] Final compaction stage: The rear protruding steel wheel 3 performs final compaction on the road surface after initial compaction. The protrusions 7 impact the road surface to form a uniform texture and enhance the interlayer bonding force. The wire brush cleaning assembly rotates at high speed when the protruding steel wheel 3 rotates, reaching deep into the gaps between the protrusions 7 to clean residual materials and prevent clogging.

[0031] Maintenance and Adjustment: When the protrusion 7 wears, the limiting plate 8 can be removed and the slide plate 6 can be pulled out to replace the protrusion assembly without replacing the entire protrusion steel wheel 3. The electric cylinder 13 drives the adjustable height of the wire brush cleaning disc 11 to ensure that it always maintains the best contact pressure with the protrusion 7, adapting to different working conditions.

[0032] This utility model features a dual-wheel synergy system that first compacts the surface and then adds texture, improving road surface quality; a self-cleaning system reduces manual intervention and increases construction efficiency; and a modular design facilitates maintenance and reduces operating costs.
