Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a road paving positioning device and a road paving method. Background Art

[0002] The elevation control method for the construction of the base or lower layer of municipal roads is mostly wire rope guidance (hanging wire method). This construction method requires a high level of technical skills of the construction personnel, and due to the self-weight of the wire rope, the center position of the two hanging points of the wire rope sags, resulting in large construction errors. At the same time, during the construction of the base or surface layer of municipal roads, the edge area cannot be effectively compacted, and the edge area often has poor compaction effect and other common quality problems; in order to ensure the construction quality of the edge area, each lower structure layer often has to reserve a working surface of about 300 mm in the edge area, and the reserved working surface needs to be cleaned in the subsequent construction, which results in serious waste of materials and labor consumption, affecting the construction period.

[0003] For example, the Chinese patent with publication number CN111979884A discloses a road paving edge baffle and a road paving method. When in use, the road paving edge baffle is placed on both sides of the road to be paved, and the position and height of the road paving edge baffle on both sides are adjusted, and fixed with fixed anchor rods and adjusting bolts. When paving, first use a paver to pave the road paving edge baffle as the elevation standard. After paving is completed and before compaction, the adjusting bolts are loosened, and then a roller is used to compact the road material. When passing through the road edge area, the roller directly rolls the road material and the road paving edge baffle. The upper L-shaped baffle and the virtual paving surface of the road material move downward together under the pressure of the roller to form a compacted surface, completing the paving of the road.

[0004] Although the above-mentioned related technologies have solved the problem of serious material waste caused by reserving a working surface of about 300 mm in the edge area and the need to clean the reserved working surface, the adjusting bolts are arranged on the vertical side panels of the L-shaped baffle, which is not conducive to adjusting and disassembling the adjusting bolts, especially when the road needs to be paved and compacted multiple times, and improvement is urgently needed.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-9 This application is described in further detail.

[0031] The present application embodiment discloses a road paving positioning device. Figure 1 The road paving positioning device comprises a first transverse plate 10, a second transverse plate 20, an anchor rod 30, a first vertical plate 40 and at least two adjusting mechanisms 50. The first transverse plate 10 is arranged in a long strip shape and extends in the horizontal direction. The second transverse plate 20 is arranged in a long strip shape and is located at the lower side of the first transverse plate 10, and the second transverse plate 20 extends in the horizontal direction. The anchor rod 30 is used to fix the second transverse plate 20 on the ground. The first vertical plate 40 is fixed to one side of the first transverse plate 10, and the first vertical plate 40 extends vertically from the first transverse plate 10 to the second transverse plate 20, and the first vertical plate 40 abuts against the edge area of ​​the road material. At least two adjusting mechanisms 50 are arranged at intervals along the length direction of the second transverse plate 20, one end of the adjusting mechanism 50 is connected to the first transverse plate 10, and the other end is connected to the second transverse plate 20, so as to adjust the distance between the first transverse plate 10 and the second transverse plate 20, so that the height of the first transverse plate 10 is consistent with the target height of the road, so as to provide a benchmark for the paving of the road material.

[0032] Reference Figure 2 and Figure 3 A second vertical plate 23 is fixed to one side of the second horizontal plate 20. The second vertical plate 23 extends from the second horizontal plate 20 toward the first horizontal plate 10 in the vertical direction. The second vertical plate 23 is slidably abutted against one side of the first vertical plate 40. The first vertical plate 40 cooperates with the second vertical plate 23 to prevent the road material from entering between the first horizontal plate 10 and the second horizontal plate 20 when paving. A telescopic rod 70 extending in the horizontal direction is fixed to the second vertical plate 23. The number of the telescopic rods 70 is more than two and they are arranged at intervals along the length direction of the second vertical plate 23. The length direction of the telescopic rod 70 is perpendicular to the length direction of the second horizontal plate 20. The telescopic rod 70 passes through the space between the first horizontal plate 10 and the second horizontal plate 20 from the second vertical plate 23. The anchor rod 30 fixes one end of the telescopic rod 70 facing away from the second vertical plate 23 to the ground. The telescopic rod 70 is a known telescopic structure, which is used to adjust two relative road paving positioning devices so that the two relative first vertical plates 40 are parallel to each other and the distance between the two relative first vertical plates 40 is equal to the design width of the road.

[0033] In some examples, the adjustment mechanism 50 includes an external threaded sleeve 51, a guide column 52, a reset elastic member 53 and an internal threaded sleeve 54. Specifically, the lower end of the external threaded sleeve 51 is connected to the second transverse plate 20, and the upper end extends vertically toward the first transverse plate 10. The upper end of the guide column 52 is fixed to the lower side of the first transverse plate 10, and the lower end extends toward the second transverse plate 20. The lower end of the guide column 52 is fixed with an outer convex ring 522, the outer diameter of the outer convex ring 522 is equal to the inner diameter of the external threaded sleeve 51, and the lower end of the guide column 52 is axially slidably connected to the external threaded sleeve 51; the upper end of the external threaded sleeve 51 is fixed with an inner convex ring 512, the inner diameter of the inner convex ring 512 is smaller than the outer diameter of the outer convex ring 522, so that the lower end of the guide column 52 and the upper end of the external threaded sleeve 51 are mutually limited, so that the other end of the guide column 52 is retained in the external threaded sleeve 51. The resetting elastic member 53 is a compression spring, and is disposed between the guide post 52 and the second transverse plate 20, so that the guide post 52 maintains a tendency to slide out of the external thread sleeve 51. The lower end of the internal thread sleeve 54 is rotatably connected to the second transverse plate 20 along the circumferential direction, and the upper end is threadedly connected to the outer side of the external thread sleeve 51, so that the distance between the first transverse plate 10 and the second transverse plate 20 can be adjusted by rotating the internal thread sleeve 54.

[0034] Furthermore, the lower end of the internal threaded sleeve 54 abuts against the upper side of the second transverse plate 20, and a rotating column 542 is coaxially fixed to the lower end of the internal threaded sleeve 54. The rotating column 542 passes through the second transverse plate 20 and is rotatably connected to the second transverse plate 20. The lower end of the rotating column 542 is provided with a retaining spring 543 abutting against the lower side of the second transverse plate 20 to rotatably connect the internal threaded sleeve 54 to the second transverse plate 20, which is convenient for disassembly and assembly.

[0035] Further, refer to Figure 3 and Figure 4The inner circumferential wall of the external threaded sleeve 51 is provided with a limiting strip 511 extending in the axial direction, and the outer circumferential wall of the guide column 52 is provided with a limiting groove 521 extending in the axial direction. The limiting strip 511 is slidably connected to the limiting groove 521 along the length direction, so that the external threaded sleeve 51 is locked on the guide column 52 along the circumferential direction, so that the external threaded sleeve 51 does not rotate when the internal threaded sleeve 54 is rotated, so that the distance between the first horizontal plate 10 and the second horizontal plate 20 can be adjusted by rotating the internal threaded sleeve 54.

[0036] When adjusting the distance between the first horizontal plate 10 and the second horizontal plate 20, the above technical solution needs to adjust each adjustment mechanism 50 one by one or multiple people need to operate multiple adjustment mechanisms 50 at the same time, which is inconvenient. Figure 3 and Figure 4 In some examples, the road paving positioning device further includes a driving mechanism 60, which is used to adjust multiple adjustment mechanisms 50 at the same time. Specifically, the driving mechanism 60 includes a driving belt ring 61 and a meshing tooth 62. The driving belt ring 61 is sleeved on the outside of all the internal thread sleeves 54, and a plurality of meshing grooves 611 are arranged at intervals along the inner side wall on the inner side of the driving belt ring 61, and the meshing grooves 611 extend axially along the internal thread sleeve 54 to the upper and lower surfaces of the driving belt ring 61. The meshing teeth 62 extend axially along the internal thread sleeve 54, and a plurality of meshing teeth 62 are uniformly arranged on the outer peripheral wall of the internal thread sleeve 54 along the circumferential direction. The meshing teeth 62 can mesh with the meshing grooves 611 to drive all the internal thread sleeves 54 to rotate through the driving belt ring 61. Optionally, the meshing teeth 62 are integrally formed with the external thread sleeve 51, or the meshing teeth 62 are slidably connected to the outer peripheral wall of the internal thread sleeve 54 along the axial direction of the internal thread sleeve 54.

[0037] In order to realize the number of rotations of the internal threaded sleeve 54 that can be selectively driven by the driving belt ring 61, preferably, the meshing teeth 62 are slidably connected to the outer peripheral wall of the internal threaded sleeve 54 along the axial direction of the internal threaded sleeve 54. The driving mechanism 60 also includes a connecting ring 63 that is slidably connected to the outer side of the internal threaded sleeve 54. The connecting ring 63 is fixedly connected to the meshing teeth 62. An embedding piece 621 is fixed to the side of the connecting ring 63 and / or at least one meshing tooth 62 facing the internal threaded sleeve 54. The embedding piece 621 extends along the axial direction of the internal threaded sleeve 54. An embedding groove 541 extending along the axial direction is provided on the outer side wall of the internal threaded sleeve 54. The embedding groove 541 extends from the upper end surface of the internal threaded sleeve 54 to the lower end surface of the internal threaded sleeve 54. The embedding piece 621 is slidably embedded in the embedding groove 541 along the axial direction of the internal threaded sleeve 54. When the connecting ring 63 moves to the first position, the meshing teeth 62 and the meshing groove 611 mesh with each other, see Figure 4 When the connecting ring 63 moves to the second position, the meshing teeth 62 are located below the meshing groove 611 and are separated from the meshing groove 611. The second position is located below the first position. Figure 5 .

[0038] Reference Figure 4 and Figure 5 Furthermore, a limiting ring 546 is integrally formed on the outer peripheral wall of the internal threaded sleeve 54, and the limiting ring 546 is coaxially arranged with the internal threaded sleeve 54. The limiting ring 546 is located in the middle of the internal threaded sleeve 54, and the limiting ring 546 abuts against the lower side of the driving belt ring 61, so that the driving belt ring 61 is maintained at the upper part of the internal threaded sleeve 54. The connecting ring 63 is located at the lower side of the limiting ring 546, so that when the connecting ring 63 moves from the first position to the second position, the limiting ring 546 prevents the driving belt ring 61 from sliding downward with the meshing teeth 62.

[0039] Generally, the road is paved horizontally, but in some special cases, the road is paved at an inclination, such as uphill or downhill. In particular, when the roadbed is not parallel to the road surface and the inclination angle is large, the above technical solution will cause large deviations when used for paving positioning, or even be unusable. Figure 6 and Figure 7 In some examples, there are two adjustment mechanisms 50, and the upper ends of the guide posts 52 of the two adjustment mechanisms 50 are both pivotally connected to the lower side of the first transverse plate 10, so that the guide posts 52 can swing left and right along the length direction of the first transverse plate 10. The lower end of the internal thread sleeve 54 of one of the adjustment mechanisms 50 is rotatably connected to the second transverse plate 20 along the circumferential direction, that is, the lower end of the internal thread sleeve 54 abuts against the upper side of the second transverse plate 20, and a rotating post 542 is coaxially fixed to the lower end of the internal thread sleeve 54, and the rotating post 542 passes through the second transverse plate 20 and is rotatably connected to the second transverse plate 20, and the lower end of the rotating post 542 is provided with a retaining spring 543 abutting against the lower side of the second transverse plate 20.

[0040] Reference Figure 6 , Figure 8 and Fig. 9, the lower end of the internal thread sleeve 54 of the other adjustment mechanism 50 is rotatably connected to the second horizontal plate 20 along the circumferential direction and can swing left and right along the length direction of the second horizontal plate 20, so that the extension lines of the first horizontal plate 10 and the second horizontal plate 20 along the length direction can intersect. Specifically, the lower end of the internal thread sleeve 54 is provided with a hinge ball 544, and the hinge ball 544 is connected to the internal thread sleeve 54 through a connecting column 545. The diameter of the connecting column 545 is smaller than the diameter of the hinge ball 544. The connecting column 545 and the hinge ball 544 are welded and fixed or integrally processed and formed. The connecting column 545 is coaxially threaded and fixed to the lower end of the internal thread sleeve 54. The second horizontal plate 20 is provided with a receiving groove 21 for the hinge ball 544 to be placed and rotated. The opening of the receiving groove 21 is set downward to facilitate the connection column 545 and the hinge ball 544 to be installed in the receiving groove 21 from bottom to top. The second transverse plate 20 is provided with a cover plate 24 covering the receiving groove 21, and the cover plate 24 abuts against the hinge ball 544 so that the hinge ball 544 is retained in the receiving groove 21. The upper side of the second transverse plate 20 is provided with a swing groove 22 extending along the length direction of the second transverse plate 20, and the swing groove 22 is connected with the receiving groove 21. The connecting column 545 passes through the swing groove 22 and can swing left and right in the swing groove 22.

[0041] When in use, first fix the second cross plate 20 on the roadbed by the anchor rod 30. At this time, the connecting rings 63 of the two driving mechanisms 60 are both in the first position. The driving mechanism 60 is used to simultaneously drive the internal threaded sleeves 54 of the two adjusting mechanisms 50 to rotate until one end of the first cross plate 10 reaches the height of the lowest point of the inclined road surface, and then slide the connecting ring 63 of the driving mechanism 60 close to the lowest point of the inclined road surface downward to the second position, and then use the driving mechanism 60 to drive the internal threaded sleeve 54 of the adjusting mechanism 50 away from the lowest point of the inclined road surface until the other end of the first cross plate 10 reaches the height of the highest point of the inclined road surface.

[0042] The implementation principle of a road paving positioning device in the embodiment of the present application is as follows: before paving the road, first lay out the line, then arrange the road paving positioning device according to the line, fix the second horizontal plate 20 on the ground by the anchor rod 30, then adjust the length of the telescopic rod 70 so that the distance between the two first vertical plates 40 arranged opposite to each other is consistent with the preset width of the road surface, and finally drive the internal threaded sleeve 54 to rotate by the driving mechanism 60 to adjust the distance and / or angle between the first horizontal plate 10 and the second horizontal plate 20 so that the upper surface of the first horizontal plate 10 is consistent with the preset road surface of the road surface, without reserving a 200mm-300mm working surface in the adjacent area, thereby reducing the waste of materials and facilitating adjustment. At the same time, when compacting the edge of the road surface, the first vertical plate 40 and the second vertical plate 23 block and limit the edge, so that the edge of the road surface is not easy to collapse or be incomplete, thereby improving the construction quality of the edge of the road surface.
