Description

Technical Field

[0001] The invention relates to a paving process for gravel slope protection along a road in road construction, and belongs to the technical field of paving gravel slope protection along a road. Background Art

[0002] The description in this section merely provides background information related to the disclosure of this specification and does not constitute prior art.

[0003] After the completion of rural cement pavement, the poured cement pavement is generally ten to thirty centimeters higher than the roadbed. Since rural roads are generally narrow, in order to prevent vehicles from driving off the road and getting stuck on the shoulder during passing, gravel needs to be paved on both sides of the road. The existing paving method generally requires a large amount of manpower to move the gravel to the shoulder position to complete the construction, making the gravel slope relatively loose. When the vehicle wheels press on the slope, it is very easy to sink. Or it is repeatedly compacted by heavy rollers, and the compaction position of the rollers needs to be repeatedly changed by operators, resulting in low construction efficiency and high labor intensity.

[0004] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of this specification and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this specification, it should not be assumed that the above technical solutions are well known to those skilled in the art.

DETAILED DESCRIPTION

[0029] In order to clearly illustrate the technical features of this solution, the following is a specific implementation method and its attached Figure 1-6 , to explain this plan.

[0030] A process for laying gravel slope protection along the road during road construction comprises the following steps:

[0031] S1. Use a material discharge engineering vehicle to pile up the gravel to be laid along one side of the road. The operator drives the gravel slope paving vehicle 1 to the working position so that the pile is located in front of the gravel slope paving vehicle 1. The push plate 2 on the front side of the gravel slope paving vehicle 1 is driven forward by the propulsion assembly 3. At the same time, the shovel plate 4 slidingly connected to the bottom of the push plate 2 is reset downward. Specifically, when the push plate 2 moves forward, the shovel plate 4 is disengaged from the roller 55, and the spring 53 is reset and pushes the shovel plate 4 to move downward so that the bottom of the shovel plate 4 contacts the road surface. In the process of moving forward, the shovel plate 4 and the push plate 2 push the gravel pile down to the road surface, and initially form a gravel slope protection;

[0032] S2, the retractable assembly 8 drives the pressure roller 11 to move forward relative to the rotating base 6 to a position above the bottom end of the gravel slope protection along the road. The clamping arm assembly 7 drives the rotating base 6 to rotate, and the rotating base 6 drives the driving pressure roller 11 to rotate, so that the driving pressure roller 11 contacts the gravel slope protection;

[0033] S3, the retractable assembly 8 drives the pressure roller 11 to move backward relative to the rotating base 6. During this process, the pressure roller 11 compacts the gravel slope protection;

[0034] S4, the retractable assembly 8 drives the pressure roller 11 to move forward relative to the rotating base 6, and the pressure roller 11 performs a compaction operation on the gravel slope protection;

[0035] S5. Repeat steps S3-S4. Before each compaction operation, ensure that the pressure roller 11 is always in contact with the gravel slope protection. If there is a gap between the pressure roller 11 and the gravel slope protection, adjust the position of the pressure roller 11 through the clamping arm assembly 7 so that the pressure roller 11 is pressed tightly against the gravel slope protection until the gravel slope protection meets the requirements.

[0036] The left and right sides of the rotating base 6 are slidably connected to side guard plates 9, and the left and right sides of the rotating base 6 are fixedly connected to limit sliders 13. The opposite sides of the two side guard plates 9 are respectively provided with limit slots 14 that slidably cooperate with the corresponding limit sliders 13. The limit sliders 13 and the limit slots 14 cooperate to ensure the stability of the compaction operation of the pressure roller 11. The front ends of the two side guard plates 9 are fixedly connected to the lifting base 10. The left and right ends of the rear side of the lifting base 10 are respectively welded with reinforcement rods 12 between the two side guard plates 9. The reinforcement rods 12 can enhance the installation and operational stability of the lifting base 10. The pressure roller 11 is rotatably connected to the lifting base 10. The top of the rotating base 6 is connected to a retractable assembly 8. The retractable assembly 8 includes a second stepper motor 81 fixedly mounted on the top of the rotating base 6. A rectangular through-hole 82 is provided on the top of the rotating base 6. A threaded sleeve 83 is rotatably connected to the inner cavity of the rectangular through-hole 82. A sprocket 84 is fixedly connected to the surface of the threaded sleeve 83 and the output shaft of the second stepper motor 81. The two sprockets 84 are connected by a chain transmission. A threaded rod 85 is fixedly connected to the rear side of the lifting base 10. The rear end of the threaded rod 85 extends through the rear side of the rotating base 6. The threaded rod 85 is threadedly connected to the threaded sleeve 83. The second stepper motor 81 rotates forward or reverse and drives the threaded sleeve 83 to rotate forward or reverse through the sprocket 84 and the chain. The rotation of the threaded sleeve 83 causes the threaded rod 85 to move forward or backward, and the threaded rod 85 drives the lifting base 10 to move synchronously.

[0037] The propulsion assembly 3 includes a threaded tube 31 extending from the front side of the curbstone slope paving vehicle 1 to the rear side of the curbstone slope paving vehicle 1. The threaded tube 31 is rotatably connected to the curbstone slope paving vehicle 1. The inner cavity of the threaded tube 31 is threadedly connected to a threaded push rod 32, and the front end of the threaded push rod 32 is fixedly connected to the rear side of the push plate 2. A stepper motor 1 33 is fixedly mounted on the rear side of the top of the curbstone slope paving vehicle 1. The rear side of the surface of the threaded tube 31 and the output shaft of the stepper motor 1 33 are both fixedly connected to pulleys 34. The two pulleys 34 are connected by a belt drive. The left and right ends of the rear side of the push plate 2 are fixedly connected to guide posts 35, and the guide posts 35 are slidably connected to the curbstone slope paving vehicle 1. The stepper motor 33 drives the threaded tube 31 to rotate through the pulley 34 and the belt. The rotation of the threaded tube 31 causes the threaded push rod 32 to move forward, and the threaded push rod 32 drives the push plate 2 to move forward synchronously, so that the push plate 2 pushes the gravel pile off the road surface.

[0038] The left and right sides of the top of the shovel plate 4 are connected to a retraction assembly 5. The retraction assembly 5 includes a sliding pin 51 fixedly connected to the top of the shovel plate 4. The left and right sides of the push plate 2 are fixedly connected to a fixed block 52. The fixed block 52 has a through hole for the sliding pin 51 to pass through and is in a clearance fit with the sliding pin 51. The surface of the sliding pin 51 is sleeved with a spring 53. The top and bottom ends of the spring 53 are respectively welded to the fixed block 52 and the shovel plate 4. The bottom of the left and right ends of the front side of the roadside gravel slope paving vehicle 1 are fixedly connected to a fixing frame 54. The opposite sides of the two fixing frames 54 are rotatably connected to rollers 55. The surface of the roller 55 is in rolling contact with the rear side of the shovel plate 4, and the rear side of the shovel plate 4 is an inclined surface inclined from the back to the front. The coordinated use of the spring 53 and the sliding pin 51 pushes the shovel plate 4 downward to reset it, so that the bottom of the shovel plate 4 can contact the road surface, avoiding the material pile being left on the road surface. At the same time, under the coordinated action of the roller 55 and the inclined surface on the rear side of the shovel plate 4, when the push plate 2 is reset backward, the inclined surface on the rear side of the shovel plate 4 contacts the roller 55. When the push plate 2 moves backward, the roller 55 can push the shovel plate 4 to rise, avoiding the shovel plate 4 from rubbing against the ground during the driving of the gravel slope paving vehicle 1.

[0039] The clamping arm assembly 7 is mounted on the top of the roadside gravel slope paving vehicle 1. The clamping arm assembly 7 includes a rotating support 71 fixedly connected to the top of the roadside gravel slope paving vehicle 1. The surface of the rotating support 71 is rotatably connected to a rotating frame 72. The front end of the rotating frame 72 is fixedly connected to the rotating base 6. The left and right ends of the front bottom of the rotating support 71 are rotatably connected to electric telescopic rods 73. The front and rear ends of the electric telescopic rod 73 are rotatably connected to connecting pieces 74. The front connecting piece 74 is fixedly connected to the rotating base 6, and the rear connecting piece 74 is fixedly connected to the rotating support 71. After adopting this structural form, the electric telescopic rod 73 can drive the rotating base 6 and the lifting base 10 to rotate relative to the rotating support 71, so that the operating height of the pressure roller 11 can be adjusted, thereby achieving the adjustment of the pressing force between the pressure roller 11 and the gravel slope surface.

[0040] Technical features not described in the present invention can be implemented by existing technologies and will not be described in detail here. The present invention is not limited to the above-mentioned specific embodiments. Changes, modifications, additions or substitutions made by ordinary technicians in this field within the scope of the essence of the present invention should also fall within the scope of protection of the present invention.
