Description

Technical Field

[0001] This application belongs to the field of road shoulder construction technology, and more specifically, relates to a road construction soil shoulder paving and compaction device. Background Technology

[0002] In road engineering, an earth shoulder refers to the edge of an asphalt concrete road, formed by compacted soil. To improve road construction quality, earth shoulders are constructed on the outer side during the construction of the water-stabilized crushed stone subbase and lower base course. The earth shoulder ensures the stability of the water-stabilized crushed stone during construction and provides support during pavement compaction, mitigating or preventing the adverse effects of lateral displacement of the structural layers on the thickness and smoothness of the edge. Current earth shoulder construction methods involve first using machinery to stockpile soil in the construction area, then manually spreading the stockpiled soil evenly, and finally compacting it with small rollers. This method is labor-intensive and inefficient. Utility Model Content

[0041] Please refer to the following: Figures 1 to 4 The following describes the road construction earth shoulder paving and compaction device provided in the embodiments of this application.

[0042] Please see Figure 1 and Figure 2This application provides a road construction earth shoulder paving and compaction device, including a mobile device 10, a pusher plate 20, a paving component 30, and a compaction component 40. The mobile device 10 is used to move along the length direction of the earth shoulder; the pusher plate 20 is located at the front end of the mobile device 10 and on the side of the mobile device 10 adjacent to the earth shoulder construction area. The pusher plate 20 includes a pusher part 21 and a stop part 22. The pusher part 21 is inclined in the forward direction of the mobile device 10 in a direction away from the earth shoulder, and the stop part 22 is located behind the pusher part 21 and parallel to the length direction of the earth shoulder. The paving assembly 30 includes a paving auger 31 and a first drive mechanism 33. The paving auger 31 is rotatably mounted on the retaining section 22, with one end connected to the retaining section 22 and the other end extending horizontally toward the earth shoulder construction area. The first drive mechanism 33 is used to drive the paving auger 31 to rotate around its own axis. The compaction assembly 40 is mounted on the mobile device 10 and located behind the paving auger 31. The compaction assembly 40 is used to compact the soil.

[0043] Compared with the prior art, the beneficial effects of the road construction earth shoulder paving and compaction device provided in this application embodiment are:

[0044] The road construction earth shoulder paving and compaction device provided in this application embodiment includes a mobile device 10, a pusher plate 20, a paving component 30, and a compaction component 40. The mobile device 10 is used to drive the pusher plate 20, the paving component 30, and the compaction component 40 to move along the length of the earth shoulder. During the movement, the pusher plate 20's pusher part 21 first pushes the earth material piled in the earth shoulder construction area to within the edge line of the earth shoulder construction area. Then, the paving auger 31 breaks up the top pile of earth material, changing the top of the earth material from a pointed pile to a relatively flat plane. Finally, the compaction component 40 compacts the earth material to obtain the formed earth shoulder.

[0045] In this embodiment, the mobile device 10 moves forward along the length of the earthen shoulder, and the pusher plate 20 concentrates the soil material within the construction area of ​​the earthen shoulder. Then, the paving auger 31 spreads the soil material evenly, and finally, the compaction component 40 compacts the soil material. This method has a higher degree of automation and can reduce the labor intensity of workers and improve construction efficiency compared with the manual paving method using tools such as shovels.

[0046] In this embodiment, the pusher plate 20, paving component 30, compaction component 40, and other components are all mounted on the mobile device 10. The mobile device 10 can be a vehicle, such as a pickup truck or tractor with a power source, or a handcart or other vehicle without a power source, which moves forward by manual pushing.

[0047] The pusher plate 20 is located at the front end of the mobile equipment 10, i.e., the cab. To facilitate the installation of the pusher plate 20 or other components, a mounting bracket can be installed on the cab, and the pusher plate 20 is mounted on the mounting bracket. The mounting bracket can be fixedly connected to the mobile equipment 10, or it can be raised and lowered using a hydraulic cylinder or jack, which facilitates the adjustment of the height of the paving auger 31 to meet the construction needs of earth shoulders of different heights.

[0048] Before construction, markings were drawn according to the designed width. Excavators and bulldozers were used to loosely lay soil that met the design and construction specifications within the marked areas on the road shoulders, and then made simple adjustments. Most of the soil piled up by excavators was within the marked areas, with a small portion outside.

[0049] The pusher plate 20 includes a pusher section 21 inclined to the earth shoulder and a retainer section 22 parallel to it, which are integrally formed and connected. The retainer section 22 is parallel to the outer edge of the earth shoulder construction area marking line, specifically it can coincide with the marking line or be located at an appropriate distance (e.g., 10 cm) inside the marking line.

[0050] As the mobile device 10 moves forward, the pusher 21 gathers the soil material located outside the marking line into the marking line. When the paving auger 31 rotates, it can transport the soil material from the edge of the construction area to the inside of the construction area and break up the cone-shaped pile of soil material at the top, making the top of the pusher tend to be flat.

[0051] One or more paving spirals 31 can be set as needed, and the specific configuration can be determined based on the actual paving effect during use.

[0052] The compaction component 40 is used to compact the spread soil material, compacting the loose soil material. The compaction component 40 can specifically adopt compaction methods such as rolling and vibration. For example, the compaction component 40 can be a roller, a compaction plate driven by a vibratory motor or hydraulic rod, or a combination of a roller and a compaction plate.

[0053] To ensure that the soil at the edge forms a vertical step surface during compaction, baffles can be installed to block and limit the soil at the edge. The baffles correspond to the material-blocking section 22. The material-blocking section 22 is used to prevent soil from falling out of the construction area during soil spreading, and the baffles are used to prevent soil from falling out of the construction area during soil compaction.

[0054] Please see Figure 1 , Figure 2 and Figure 3 In some possible embodiments, multiple paving augers 31 are spaced apart along the forward direction of the mobile device 10, and the height of the multiple paving augers 31 decreases from front to back. The multiple paving augers 31 can break up and spread the material pile on top of the soil layer by layer, resulting in a high degree of flatness of the paved soil.

[0055] An appropriate distance can be left between the paving component 30 and the compaction component 40. If uneven soil distribution still exists in some areas after the paving component 30 has passed, these areas can be manually repaired, thus ensuring the paving quality of the earth shoulder. Understandably, even if this device may require manual assistance in actual application, it still has the advantages of saving labor and improving paving efficiency compared to relying entirely on manual paving.

[0056] Please see Figure 1 , Figure 3 and Figure 4 In some possible embodiments, the compaction assembly 40 includes a vibratory mechanism 41 and a compaction wheel 42. The vibratory mechanism 41 is located on one side of the mobile equipment 10 and behind the paving auger 31; the compaction wheel 42 is located on one side of the mobile equipment 10 and behind the vibratory mechanism 41.

[0057] In this embodiment, the compaction component 40 adopts a compaction method combining vibration and rolling. First, the vibrating mechanism 41 compacts the spread soil material, and then the compaction wheel 42 rolls the soil material. The vibrating mechanism 41 can fully compact the soil material, and the rolled soil shoulder surface is flat and aesthetically pleasing. The compaction wheel 42 is usually made of steel, and the length of the compaction wheel 42 corresponds to the width of the soil shoulder.

[0058] The installation height of the compaction component 40 can be fixed or adjustable, and can be driven by a hydraulic cylinder or a scissor lift.

[0059] The rotation of the paving auger 31 can be driven by a motor or by a power source of the driving equipment (such as an engine) through chain drive, gear drive, or other means. The compaction wheel 42 is rotatably mounted on the moving equipment 10. It can rotate actively, i.e., driven by a motor or other driving components, or it can rotate passively, i.e., the drive shaft of the compaction wheel 42 is not connected to the power unit.

[0060] Please see Figure 1 , Figure 2 and Figure 3 In some possible embodiments, multiple compaction wheels 42 are spaced apart along the forward direction of the mobile device 10, and the compaction height of the multiple compaction wheels 42 decreases from front to back. At least one compaction wheel 42 is located on the side of the material retaining part 22 adjacent to the earth shoulder construction area and behind the paving auger 31. At least one compaction wheel 42 is located behind the vibrating mechanism 41.

[0061] In this embodiment, the soil material undergoes a series of steps including spreading, compaction, vibration, and re-compaction, enabling layered compaction of the soil material with good compaction effect. At least one compaction wheel 42 is located behind the vibration mechanism 41, and the surface of the soil material after being compacted by the compaction wheel 42 is smooth and aesthetically pleasing.

[0062] Please see Figure 1 , Figure 3 and Figure 4 In some possible embodiments, the tamping mechanism 41 includes a tamping hammer 411 and a tamping drive unit. The tamping hammer 411 is located behind the paving auger 31 and includes a pressure plate and a hammer rod connected above the pressure plate; the tamping drive unit is located on the moving device 10 and is used to drive the tamping hammer 411 to move up and down.

[0063] In this embodiment, the vibratory hammer 411 consists of a pressure plate and a hammer rod. The bottom of the pressure plate is flat and used to contact the soil. The hammer rod and the pressure plate can be connected together by welding, screws, or other methods. The vibration drive unit can be a vibratory motor, a liftable hydraulic cylinder, or a pneumatic push rod, or a common linear reciprocating movement mechanism such as a motor-driven crank-slider mechanism or a gear and rack mechanism, as long as it can drive the vibratory hammer 411 to move up and down to achieve vibration.

[0064] Please see Figure 4 In some possible embodiments, the vibratory drive unit includes a drive wheel 412 and a connecting rod 413. The drive wheel 412 is rotatably mounted on the mobile device 10 about a horizontal axis, and the top end of the hammer rod is eccentrically rotatably connected to the drive wheel 412; one end of the connecting rod 413 is rotatably connected to the bottom end of the hammer rod, and the other end is rotatably connected to the mobile device 10.

[0065] In this embodiment, the vibration drive unit consists of a drive wheel 412 and a connecting rod 413 assembly. The drive wheel 412 is disc-shaped, and its central axis is connected to the power device via gears, chains, and other transmission components, enabling it to rotate around a horizontal axis. The drive wheel 412 is eccentrically connected to the hammer rod, and one end of the connecting rod 413 is hinged to the bottom end of the hammer rod, while the other end is hinged to a corresponding rotating shaft on the mobile device 10. When the drive wheel 412 rotates, it can drive the vibratory hammer 411 to reciprocate in the up-down direction, thereby vibrating and compacting the soil.

[0066] It should be noted that in this embodiment, the vibratory hammer 411 can move up and down to vibrate the soil. However, due to the drive wheel 412 used in this embodiment, the vibratory hammer 411 does not move vertically up and down during operation, but is tilted, which can meet the requirements of soil compaction.

[0067] Please see Figure 1 and Figure 2In some possible embodiments, multiple vibrating mechanisms 41 are spaced apart in the horizontal direction, and the arrangement direction of the multiple vibrating mechanisms 41 is perpendicular to the forward direction of the mobile device 10. The specific number of vibrating mechanisms 41 can be determined according to the size of the compaction plate and the construction width of the earth shoulder.

[0068] Please see Figure 1 , Figure 2 and Figure 3 In some possible embodiments, the mobile device 10 is also provided with an auxiliary shaping plate 11 on the side adjacent to the construction area of ​​the earth shoulder. The auxiliary shaping plate 11 is a vertical flat plate. The auxiliary shaping plate 11 is located at the edge of the earth shoulder construction area. The front end of the auxiliary shaping plate 11 is located behind the pusher plate 20, and the rear end of the auxiliary shaping plate 11 is located behind the vibrating mechanism 41. When the vibrating mechanism 41 is working, the auxiliary shaping plate can block and limit the soil material to prevent the soil material from overflowing the edge of the earth shoulder construction area.

[0069] Please see Figure 1 and Figure 2 In some possible embodiments, the road construction earth shoulder paving and compaction device also includes a water spraying assembly, which includes a water tank 50 and a water spraying mechanism. The water tank 50 is located on the mobile device 10; the water spraying mechanism is located on the mobile device 10, with its inlet end connected to the water tank 50 and its outlet end located above the earth shoulder construction area. When the soil is too dry, water can be sprayed onto the soil through the water tank 50 and the water spraying mechanism to improve the soil's compaction ability.

[0070] The sprinkler system can be based on existing sprinkler heads, connected to the water tank 50 via valves and water pipes, and supplied with water by a water pump installed in the water tank 50. The amount and speed of water spraying can be adjusted as needed.

[0071] Depending on the needs, the water outlet of the sprinkler system can be located in front of the pusher plate 20, or between the paving auger 31 and the compaction component 40. In addition to wetting the soil, the heavy weight of the water tank 50 can also increase the weight of the mobile device 10, thereby increasing the compaction force applied to the soil by the compaction component 40.

[0072] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
