Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically a water-stabilized layer paving and compaction device. Background Technology

[0002] In the paving of water-stabilized base courses, the quality of treatment of joints such as longitudinal and transverse joints directly affects the overall strength and service life of the road, making it a critical aspect of construction. Traditional construction methods often involve using ordinary pavers for overall paving and then relying on external rollers to compact the joint areas, without dedicated joint treatment mechanisms, which has significant shortcomings.

[0003] First, the lack of an adjustable and positioning retaining structure makes it easy for material to collapse and the edges to become irregular at the joint ends, making it difficult to form a smooth interface during subsequent compaction. Second, the compaction operation is not synchronized with the paving operation, and there are blind spots in the compaction of the external roller. Furthermore, the compaction height cannot be flexibly adjusted according to the joint position, which cannot meet the requirements of high-quality road construction. Utility Model Content

[0004] The purpose of this invention is to provide a water-stabilized layer paving and compaction device to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a water-stabilized layer paving and compaction device, including a paver body and two base frames connected to the paver body. Two symmetrically arranged sliding rods are installed between the two base frames. A slidingly positionable adjusting component is provided between the adjacent ends of the two sliding rods. A lifting component is installed below the moving end of the adjusting component. A baffle for blocking the end joint of the water-stabilized layer is connected to the bottom end of the lifting component. An adjustable height vibratory compaction component is installed on one side of the lifting component.

[0006] The aforementioned components achieve the following effects: the base frame and slide rod form a support frame; the adjustable distance component drives the lifting component, baffle, and vibratory compaction component to move laterally along the slide rod, adapting to joint positions of different widths; the lifting component adjusts the baffle height to adapt to the thickness of the water-stabilized layer and adjusts the height of the vibratory compaction component to adapt to the compaction requirements; the baffle blocks material to ensure the neatness of the joint; and the vibratory compaction component compacts the joint area. This achieves the goal of flexibly adapting the device to different joint positions and construction scenarios with different water-stabilized layer thicknesses, increasing the device's construction applicability, and improving the neatness of the material blocking and the targeted compaction of the water-stabilized layer joints.

[0007] Preferably, the adjustable distance assembly includes an electric telescopic rod installed on one side of the base frame. The telescopic end of the electric telescopic rod is fixed with a slide block that is slidably sleeved on the slide rod. A connecting rod is fixed between the slide blocks on adjacent ends of the two slide rods. The bottom end of the slide block is connected to the lifting assembly.

[0008] The effect achieved by the above components is as follows: when the electric telescopic rod extends or retracts, it drives the slide block fixed to it to slide along the slide rod, and at the same time, it pulls the slide block on the other side to slide synchronously through the connecting rod, thereby enabling the lifting assembly and subsequent components connected to the bottom of the slide block to achieve lateral distance adjustment; thus achieving the purpose of precise and synchronous adjustment of the lateral position of the joint treatment-related components.

[0009] Preferably, the lifting assembly includes a bracket connected to the slide block, a first electric lifting rod is mounted on the bracket, a base frame connected to the top of the baffle is fixed at the bottom end of the first electric lifting rod, a guide rod is fixed at the top of the base frame and slidably inserted into the bracket, and the vibration compaction assembly is mounted on one side of the bracket.

[0010] The effects achieved by the above components are as follows: when the first electric lifting rod extends or retracts, it pushes the base frame to move up and down, and the base frame drives the baffle to rise and fall synchronously. At the same time, the guide rod slides along the inner wall of the bracket to limit the offset direction of the base frame and ensure the stability of the baffle lifting process. It achieves the purpose of the baffle height being able to accurately adapt to different water-stabilized layer thicknesses, avoids the irregularity of the baffle caused by the offset of the baffle during the lifting process, increases the stability of the lifting structure, and improves the positioning accuracy of the baffle and the flatness of the joint edges.

[0011] Preferably, the compaction assembly includes a side frame connected to the bracket, a second electric lifting rod is mounted on the side frame, and a high-frequency vibratory compaction wheel is mounted at the bottom end of the second electric lifting rod.

[0012] The effects achieved by the above components are as follows: when the second electric lifting rod extends or retracts, it drives the high-frequency vibratory compaction wheel to move up and down. According to the compaction requirements of the joint area of ​​the water-stabilized layer, the contact pressure and depth between the high-frequency vibratory compaction wheel and the surface of the water-stabilized layer are adjusted. At the same time, the high-frequency vibratory compaction wheel itself vibrates to carry out compaction work. This achieves the goal of flexibly adapting the height of the high-frequency vibratory compaction wheel to different compaction scenarios, avoiding the problem of insufficient or excessive compaction caused by a fixed height of the compaction wheel, increasing the flexibility of compaction work, and improving the compaction density of the joint area.

[0013] Preferably, the high-frequency vibratory compaction wheel includes a rotating base and a compaction wheel rotatably installed in the rotating base. An eccentric block vibrator is installed in the compaction wheel, and the eccentric block vibrator is driven by a variable frequency motor.

[0014] The effects achieved by the above components are as follows: after the variable frequency motor starts, it drives the eccentric block vibrator to rotate. The eccentric rotation of the eccentric block vibrator generates high-frequency vibration, which is transmitted to the compaction wheel. While the compaction wheel rolls in the rotating seat, it applies high-frequency vibration to the joint area of ​​the water-stabilized layer. The vibration frequency can be changed by adjusting the speed of the variable frequency motor. This achieves the goal of flexibly adjusting the vibration frequency according to the material characteristics of the water-stabilized layer, avoiding the problem of poor adaptability of a single frequency.

[0015] Preferably, a guide end plate is provided at the end of the baffle that is close to the travel direction of the paver body.

[0016] The effect achieved by the above components is as follows: when the paver moves forward to pave the water-stabilized layer, the guide end plate first contacts the water-stabilized layer material to be paved. Through the inclined or arc-shaped structure of the guide end plate, the material is smoothly guided to the inside of the baffle, avoiding the accumulation of material at the baffle end or the collapse to the outside. This achieves the purpose of smooth transition and regular accumulation of water-stabilized layer material at the joint, avoiding the bulging or collapse of the joint edge caused by material accumulation.

[0017] Preferably, the base frame end is provided with connecting corner blocks for assembling and connecting the paver body.

[0018] The effect achieved by the above components is as follows: by using the bolt holes or connecting buckles on the connecting corner blocks, the corresponding installation positions of the base frame and the paver body are aligned, and the base frame and the paver body are detachably connected by bolt tightening or buckle engagement, thereby assembling the entire device and the paver body into one unit.

[0019] This utility model provides an improved water-stabilized layer paving and compaction device, which has the following improvements and advantages compared with the prior art:

[0020] Firstly, this utility model uses an adjustable distance component to drive the lifting component, baffle, and compaction component to move laterally along the slide bar, adapting to joint positions of different widths. The lifting component adjusts the height of the baffle to adapt to the thickness of the water-stabilized layer and adjusts the height of the compaction component to adapt to the compaction requirements. The baffle blocks the material to ensure the joint is neat, and the compaction component compacts the joint area. This achieves the purpose of the device being flexibly adaptable to construction scenarios with different joint positions and different water-stabilized layer thicknesses, increasing the construction applicability of the device and improving the neatness of the material blocking and the targeted compaction of the water-stabilized layer joints.

[0021] Secondly, when the paver body moves forward to pave the water-stabilized layer, the guide end plate first contacts the water-stabilized layer material to be paved. Through the inclined or arc-shaped structure of the guide end plate, the material is smoothly guided to the inside of the baffle, avoiding the material from accumulating at the end of the baffle or collapsing to the outside, thus achieving the purpose of smooth transition and orderly accumulation of water-stabilized layer material at the joint.

[0029] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0030] This utility model provides an improved device for paving and compacting water-stabilized layers. The technical solution of this utility model is as follows:

[0031] In embodiments of this utility model, such as Figures 1-4 As shown, a water-stabilized layer paving and compaction device includes a paver body and two base frames 1 connected to the paver body. Each base frame 1 has connecting corner blocks 8 for assembling and connecting the paver body. Using bolt holes or connecting clips on the connecting corner blocks 8, the corresponding installation positions of the base frames 1 and the paver body are aligned. A detachable connection between the base frames 1 and the paver body is achieved by tightening bolts or engaging clips. Two symmetrically arranged sliding rods 2 are installed between the two base frames 1. A slidable positioning adjustment assembly 3 is provided between adjacent ends of the two sliding rods 2. The adjustment assembly 3 includes a mounting... On one side of the base frame 1, there is an electric telescopic rod 32. The telescopic end of the electric telescopic rod 32 is fixed with a sliding seat 31 that is slidably sleeved on the slide rod 2. A connecting rod 33 is fixed between the sliding seats 31 on the adjacent ends of the two slide rods 2. The bottom end of the sliding seat 31 is connected to the lifting assembly 4. When the electric telescopic rod 32 extends or retracts, it drives the sliding seat 31 fixed to it to slide along the slide rod 2. At the same time, the connecting rod 33 pulls the sliding seat 31 on the other side to slide synchronously, thereby enabling the lifting assembly 4 and subsequent components connected to the bottom end of the sliding seat 31 to achieve lateral spacing adjustment. This achieves the purpose of precise and synchronous adjustment of the lateral position of the joint treatment-related components.

[0032] A lifting assembly 4 is installed below the moving end of the adjusting assembly 3. The lifting assembly 4 includes a bracket 41 connected to the slide 31. A first electric lifting rod 42 is installed on the bracket 41. A base frame 44 connected to the top of the baffle 5 is fixed at the bottom end of the first electric lifting rod 42. A guide rod 43 that slides on the bracket 41 is fixed at the top of the base frame 44. The vibration assembly 7 is installed on one side of the bracket 41. When the first electric lifting rod 42 extends or retracts, it pushes the base frame 44 to move up and down. The base frame 44 drives the baffle 5 to rise and fall synchronously. At the same time, the guide rod 43 slides along the inner wall of the bracket 41 to limit the offset direction of the base frame 44.

[0033] The bottom end of the lifting assembly 4 is connected to a baffle 5 for blocking the end joint of the water-stabilized layer. A guide plate 6 is provided at the end of the baffle 5 near the direction of travel of the paver body. When the paver body moves forward to pave the water-stabilized layer, the guide plate 6 first contacts the water-stabilized layer material to be paved. Through the inclined or arc-shaped structure of the guide plate 6, the material is smoothly guided to the inside of the baffle 5 to avoid the material from accumulating at the end of the baffle 5 or collapsing to the outside.

[0034] An adjustable-height vibratory compaction assembly 7 is installed on one side of the lifting assembly 4. The vibratory compaction assembly 7 includes a side frame 71 connected to the bracket 41. A second electric lifting rod 72 is installed on the side frame 71. A high-frequency vibratory compaction wheel 73 is installed at the bottom of the second electric lifting rod 72. When the second electric lifting rod 72 extends or retracts, it drives the high-frequency vibratory compaction wheel 73 to move up and down. According to the compaction requirements of the joint area of ​​the water-stabilized layer, the contact pressure and depth between the high-frequency vibratory compaction wheel 73 and the surface of the water-stabilized layer are adjusted. At the same time, the high-frequency vibratory compaction wheel 73 itself generates vibration to carry out compaction. The high-frequency vibratory compaction wheel 73 includes a rotating seat and a compaction wheel rotatably installed in the rotating seat. An eccentric block vibrator is installed in the compaction wheel. The eccentric block vibrator is driven by a variable frequency motor. After the variable frequency motor starts, it drives the eccentric block vibrator to rotate. The eccentric rotation of the eccentric block vibrator generates high-frequency vibration, which is transmitted to the compaction wheel. While the compaction wheel rolls in the rotating seat, it applies high-frequency vibration to the joint area of ​​the water-stabilized layer. The vibration frequency can be changed by adjusting the speed of the variable frequency motor.

[0035] The working principle of the water-stabilized layer paving and compaction device provided by this utility model is as follows: Device assembly and positioning:

[0036] First, align the base frame 1 with the corresponding installation position of the paver body by connecting corner block 8 on the end side of the base frame 1. Then, use bolts or snap-fit ​​to achieve a detachable connection between the base frame 1 and the paver body, so that the entire device is assembled with the paver body as one unit, providing basic support for subsequent operations.

[0037] Lateral position adjustment: Activate the electric telescopic rod 32 in the adjustment assembly 3. When the electric telescopic rod 32 extends and retracts, it drives the slide block 31 fixed at its telescopic end to slide along the slide rod 2 installed between the two base frames 1. At the same time, the slide blocks 31 on the adjacent ends of the two slide rods 2 are synchronously linked through the connecting rod 33, which in turn drives the lifting assembly 4, baffle 5 and vibration assembly 7 connected to the bottom end of the slide block 31 to move along the slide rod 2 until the baffle 5 and vibration assembly 7 are aligned with the longitudinal or transverse joint of the water-stabilized layer to be treated.

[0038] Vertical height adaptation: For the thickness of the water-stabilized layer, the first electric lifting rod 42 in the lifting assembly 4 is activated. The first electric lifting rod 42 extends and retracts to push the bottom frame 44 to move up and down. The bottom frame 44 drives the baffle 5 connected to the top to rise and fall synchronously. During this period, the guide rod 43 at the top of the bottom frame 44 slides along the inner wall of the bracket 41 to prevent the baffle 5 from shifting until the height of the baffle 5 matches the thickness of the water-stabilized layer. At the same time, the second electric lifting rod 72 in the vibration compaction assembly 7 is activated. The second electric lifting rod 72 extends and retracts to drive the high-frequency vibration compaction wheel 73 at the bottom to move up and down, so that the high-frequency vibration compaction wheel 73 contacts the surface of the joint area of ​​the water-stabilized layer to adapt to the compaction depth requirements.

[0039] Paving and material blocking operation: When the paver moves forward to pave the water-stabilized layer, the guide end plate 6 of the baffle 5, which is close to the direction of travel of the paver, first contacts the water-stabilized layer material to be paved. The material is smoothly guided to the inside of the baffle 5 by the guiding action of the guide end plate 6. The baffle 5 then blocks and limits the joints on the side of the water-stabilized layer to prevent the material from collapsing and to ensure that the edges of the joints are neat.

[0040] Joint compaction operation: During paving, the variable frequency motor inside the high-frequency vibratory compaction wheel 73 is started. The variable frequency motor drives the eccentric block vibrator to rotate and generate high-frequency vibration, which is transmitted to the high-frequency vibratory compaction wheel 73. The high-frequency vibratory compaction wheel 73 rolls in the rotating seat as the paver moves forward, applying high-frequency vibration to the joint area of ​​the water-stabilized layer to achieve joint compaction. The vibration frequency can be changed by adjusting the speed of the variable frequency motor according to the characteristics of the water-stabilized layer material to ensure the joint density and structural strength.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
