Description

Technical Field

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

[0002] For the construction of the base layer or the lower surface layer of municipal roads, the elevation control method is mostly wire rope guidance (suspended wire method). This construction method has high requirements for the technical level of construction workers. Moreover, due to the self-weight of the wire rope, the center position of the two suspension points of the wire rope sags, resulting in large construction errors. At the same time, during the construction of the base layer or surface layer of municipal roads, the adjacent edge areas cannot be effectively compacted, and common quality problems such as poor compaction effect often occur in the adjacent edge areas. To ensure the construction quality of the adjacent edge areas, an operating surface of about 300 millimeters is often reserved in the adjacent edge areas for each lower structural layer, and the reserved operating surface needs to be cleaned during subsequent construction, resulting in relatively serious material waste, consuming manpower, and affecting the construction period.

[0003] For example, Chinese Patent with publication number CN111979884A discloses a road paving adjacent edge baffle and a road paving method. When in use, the road paving adjacent edge baffle is placed on both sides of the road to be paved, the positions and heights of the road paving adjacent edge baffles on both sides are adjusted, and fixed anchor bolts and adjusting bolts are used for fixing. During paving, the paver first uses the height of the road paving adjacent edge baffle as the elevation standard for paving. After paving is completed and before compaction construction, the adjusting bolts are loosened, and then a roller is used to compact the road material. When passing through the adjacent edge area of the road, the roller directly compacts the road material and the road paving adjacent edge baffle. The virtual paving surfaces of the upper L-shaped baffle and 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 related technology solves the problems of relatively serious material waste caused by reserving an operating surface of about 300 millimeters in the adjacent edge area and the need to clean the reserved operating surface, the adjusting bolts are arranged on the vertical side plate 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, it urgently needs to be improved. Summary of the Invention

[0005] In order to facilitate adjustment and use, the present application provides a road paving positioning device and a road paving method.

[0006] In a first aspect, the present application provides a road paving positioning device, adopting the following technical solution:

[0007] A road paving positioning device includes:

[0008] A first horizontal plate, which is arranged in a long strip shape;

[0009] The second horizontal plate is strip-shaped and located below the first horizontal plate;

[0010] The anchor rod is used to fix the second horizontal plate to the ground;

[0011] The first vertical plate is fixed to one side of the first horizontal plate and extends vertically towards the second horizontal plate; and

[0012] At least two adjusting mechanisms are arranged at intervals along the length direction of the second horizontal plate. The adjusting mechanism includes:

[0013] The external thread sleeve has one end connected to the second horizontal plate and the other end extending towards the first horizontal plate;

[0014] The guide post has one end connected to the first horizontal plate and the other end extending towards the second horizontal plate. The other end of the guide post is slidably connected to the external thread sleeve along the axis and is mutually limited with the other end of the external thread sleeve, so that the other end of the guide post is kept in the external thread sleeve;

[0015] The reset elastic member is arranged between the guide post and the second horizontal plate, so that the guide post has a tendency to slide out of the external thread sleeve; and

[0016] The internal thread sleeve has one end rotatably connected to the second horizontal plate along the circumferential direction and the other end threadedly connected to the outside of the external thread sleeve.

[0017] By adopting the above technical solution, the distance between the first horizontal plate and the second horizontal plate is adjusted through the threaded connection between the internal thread sleeve and the external thread sleeve, so that the height of the first horizontal plate is consistent with the preset height of the road surface. There is no need to reserve a working surface of 200 mm - 300 mm in the edge area, reducing material waste. Moreover, the adjusting mechanism is located between the first horizontal plate and the second horizontal plate and does not contact the road surface material, facilitating adjustment and use. When compacting the road surface edge, the first vertical plate blocks and limits the edge, making it difficult for the road surface edge to collapse or be incomplete, improving the construction quality of the road surface edge.

[0018] Optionally, it further includes a driving mechanism. The driving mechanism includes:

[0019] The driving belt ring is sleeved on the outside of all the internal thread sleeves. A plurality of meshing grooves are arranged at intervals along the inner side wall of the driving belt ring and extend along the axis of the internal thread sleeve; and

[0020] The meshing teeth are uniformly arranged on the outer peripheral wall of the internal thread sleeve along the circumferential direction. The meshing teeth can be meshed with the meshing grooves to drive at least one of the internal thread sleeves to rotate through the driving belt ring.

[0021] By adopting the above technical solution, the mutual engagement of the driving belt ring and the meshing teeth can drive the internal thread sleeves of all the adjusting mechanisms to rotate synchronously, without the need to adjust multiple adjusting mechanisms one by one or by multiple people simultaneously, so as to improve the use efficiency of the road paving positioning device.

[0022] Optionally, the driving mechanism further includes a connecting ring slidably connected to the outer side of the internal thread sleeve. The connecting ring is fixedly connected to the meshing teeth. An embedding member is fixed to one side of the connecting ring and / or at least one of the meshing teeth facing the internal thread sleeve. An embedding groove extending axially is provided on the outer side wall of the internal thread sleeve. The embedding member is slidably embedded in the embedding groove along the axial direction of the internal thread sleeve.

[0023] When the connecting ring moves to the first position, the meshing teeth are engaged with the meshing groove; when the connecting ring moves to the second position, the meshing teeth are located below the meshing groove and separated from the meshing groove. The second position is located below the first position.

[0024] By adopting the above technical solution, moving the connecting ring can drive the meshing teeth to be engaged with or separated from the meshing groove, so as to selectively adjust the lengths of the respective adjusting mechanisms through the driving mechanism, thereby realizing the adjustment of the distance between the first cross plate and the second cross plate to adapt to more complex paving conditions during road paving.

[0025] Optionally, one end of the guide post is fixedly connected to the first cross plate, and one end of the internal thread sleeve is rotatably connected to the second cross plate in the circumferential direction.

[0026] Optionally, there are two adjusting mechanisms. One end of the guide post is pivotally connected to the first cross plate. One end of one internal thread sleeve is rotatably connected to the second cross plate in the circumferential direction. One end of the other internal thread sleeve is rotatably connected to the second cross plate in the circumferential direction and can swing left and right along the length direction of the second cross plate, so that the extension lines of the first cross plate and the second cross plate in the length direction can intersect.

[0027] Optionally, one end of one internal thread sleeve abuts against the upper side of the second cross plate. A rotating column is coaxially fixed to one end of this internal thread sleeve. The rotating column penetrates the second cross plate and is rotatably connected to the second cross plate. A snap spring abutting against the lower side of the second cross plate is provided at the end of the rotating column facing away from this internal thread sleeve.

[0028] Optionally, a hinge ball is provided at one end of the other internal thread sleeve. The hinge ball is connected to this internal thread sleeve through a connecting column. A receiving groove for placing and rotating the hinge ball is provided on the second cross plate. A swinging groove communicating with the receiving groove and extending along the length direction of the second cross plate is provided on the side of the second cross plate facing the first cross plate. The connecting column can swing left and right in the swinging groove.

[0029] Optionally, the reset elastic member is a compression spring. One side of the second horizontal plate is fixed with a second vertical plate, and the second vertical plate is slidably abutted against the first vertical plate in the vertical direction.

[0030] Optionally, a limiting strip extending along the axial direction is provided on the inner peripheral wall of the external thread sleeve, a limiting groove extending along the axial direction is provided on the outer peripheral wall of the guide post, and the limiting strip is slidably connected to the limiting groove in the length direction.

[0031] In a second aspect, the present application provides a road paving method, adopting the following technical solution:

[0032] A road paving method, applying the road paving positioning device as described above, at least includes the following steps:

[0033] S1. Lay out lines at the edge positions on both sides of the road, and arrange the road paving positioning devices along the projection of the laid-out lines on the ground;

[0034] S2. Adjust the distance between the first horizontal plate and the second horizontal plate through the adjusting mechanism according to the height of the road, so that the first horizontal plate is consistent with the target height;

[0035] S3. Fix the road paving positioning device to the ground through the anchor rod, so that the distance between the road paving positioning devices on both sides of the road is consistent with the target width of the road surface;

[0036] S4. Use a paver to spread materials between the road paving positioning devices on both sides of the road, and the height control sensor of the paver takes the first horizontal plate as the standard;

[0037] S5. Use a roller to carry out road surface compaction construction.

[0038] By adopting the above technical solution, the distance between the first horizontal plate and the second horizontal plate is adjusted through the threaded connection between the internal thread sleeve and the external thread sleeve, so that the height of the first horizontal plate is consistent with the preset height of the road surface. There is no need to reserve a working surface of 200 mm - 300 mm in the adjacent area, reducing material waste. Moreover, the adjusting mechanism is located between the first horizontal plate and the second horizontal plate and does not contact the road surface material, facilitating adjustment and use. When compacting the road surface edge, the first vertical plate blocks and limits the edge, making it difficult for the road surface edge to collapse and be incomplete, improving the construction quality of the road surface edge.

Detailed implementation manners

[0049] The following further describes the present application in detail with reference to the attached Figures 1-9 drawings.

[0050] Embodiment 1 of the present application discloses a road paving positioning device. Refer to Figure 1, the road paving positioning device includes a first cross plate 10, a second cross plate 20, an anchor rod 30, a first vertical plate 40 and at least two adjusting mechanisms 50. The first cross plate 10 is arranged in a long strip shape and extends in the horizontal direction. The second cross plate 20 is arranged in a long strip shape and is located below the first cross plate 10, and the second cross plate 20 extends in the horizontal direction. The anchor rod 30 is used to fix the second cross plate 20 to the ground. The first vertical plate 40 is fixed to one side of the first cross plate 10, and the first vertical plate 40 extends vertically from the first cross plate 10 towards the second cross 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 cross plate 20. One end of the adjusting mechanism 50 is connected to the first cross plate 10, and the other end is connected to the second cross plate 20 to adjust the distance between the first cross plate 10 and the second cross plate 20, so that the height of the first cross plate 10 is consistent with the target height of the road, providing a reference for road material paving.

[0051] Refer to Figure 2 And Figure 3 , a second vertical plate 23 is fixed to one side of the second cross plate 20. The second vertical plate 23 extends vertically from the second cross plate 20 towards the first cross plate 10, and the second vertical plate 23 slidably abuts against one side of the first vertical plate 40. The first vertical plate 40 and the second vertical plate 23 cooperate to prevent the road material from entering between the first cross plate 10 and the second cross plate 20 during paving. A telescopic rod 70 extending in the horizontal direction is fixed to the second vertical plate 23. The number of 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 cross plate 20. The telescopic rod 70 passes through the space between the first cross plate 10 and the second cross plate 20 from the second vertical plate 23, and the anchor rod 30 fixes the 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 and is used to adjust two opposite road paving positioning devices so that two opposite first vertical plates 40 are parallel to each other and the distance between two opposite first vertical plates 40 is equal to the designed width of the road.

[0052] In some examples, the adjusting mechanism 50 includes an external thread sleeve 51, a guide post 52, a reset elastic member 53 and an internal thread sleeve 54. Specifically, the lower end of the external thread sleeve 51 is connected to the second cross plate 20, and the upper end extends vertically towards the first cross plate 10. The upper end of the guide post 52 is fixed to the lower side of the first cross plate 10, and the lower end extends towards the second cross plate 20. An external convex ring 522 is fixed to the lower end of the guide post 52, and the outer diameter of the external convex ring 522 is equal to the inner diameter of the external thread sleeve 51. The lower end of the guide post 52 is slidably connected to the external thread sleeve 51 along the axial direction; an internal convex ring 512 is fixed to the upper end of the external thread sleeve 51, and the inner diameter of the internal convex ring 512 is smaller than the outer diameter of the external convex ring 522, so that the lower end of the guide post 52 and the upper end of the external thread sleeve 51 are mutually limited, and thus the other end of the guide post 52 is retained in the external thread sleeve 51. The reset elastic member 53 is a compression spring, and the reset elastic member 53 is arranged between the guide post 52 and the second cross plate 20, so that the guide post 52 has 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 cross plate 20 along the circumferential direction, and the upper end is threadedly connected to the outside of the external thread sleeve 51. Thus, the distance between the first cross plate 10 and the second cross plate 20 can be adjusted by rotating the internal thread sleeve 54.

[0053] Further, the lower end of the internal thread sleeve 54 abuts against the upper side of the second cross plate 20. A rotating column 542 is coaxially fixed to the lower end of the internal thread sleeve 54. The rotating column 542 penetrates through the second cross plate 20 and is rotatably connected to the second cross plate 20. A snap spring 543 is provided at the lower end of the rotating column 542 and abuts against the lower side of the second cross plate 20, so as to rotatably connect the internal thread sleeve 54 to the second cross plate 20, which is convenient for disassembly and assembly.

[0054] Further, referring to Figure 3 and Figure 4 , a limiting strip 511 extending along the axial direction is provided on the inner peripheral wall of the external thread sleeve 51, and a limiting groove 521 extending along the axial direction is provided on the outer peripheral wall of the guide post 52. The limiting strip 511 is slidably connected to the limiting groove 521 along the length direction, so that the external thread sleeve 51 is locked to the guide post 52 in the circumferential direction. Thus, when the internal thread sleeve 54 is rotated, the external thread sleeve 51 does not rotate, which is convenient for adjusting the distance between the first cross plate 10 and the second cross plate 20 by rotating the internal thread sleeve 54.

[0055] When adjusting the distance between the first cross plate 10 and the second cross plate 20 in the above technical solution, it is necessary to adjust each adjusting mechanism 50 one by one or multiple people operate multiple adjusting mechanisms 50 simultaneously, and the operation is inconvenient. In view of this, continue to refer to Figure 3 and Figure 4, in some examples, the road paving positioning device further includes a driving mechanism 60, and the driving mechanism 60 is used to adjust a plurality of adjusting mechanisms 50 simultaneously. Specifically, the driving mechanism 60 includes a driving belt ring 61 and engaging teeth 62. The driving belt ring 61 is sleeved outside all the inner threaded sleeves 54. A plurality of engaging grooves 611 are arranged at intervals along the inner side wall of the driving belt ring 61, and the engaging grooves 611 extend along the axial direction of the inner threaded sleeve 54 to the upper and lower surfaces of the driving belt ring 61. The engaging teeth 62 extend along the axial direction of the inner threaded sleeve 54, and a plurality of engaging teeth 62 are uniformly arranged on the outer peripheral wall of the inner threaded sleeve 54 along the circumferential direction. The engaging teeth 62 can be engaged with the engaging grooves 611 to drive all the inner threaded sleeves 54 to rotate through the driving belt ring 61. Optionally, the engaging teeth 62 and the outer threaded sleeve 51 are integrally formed, or the engaging teeth 62 are slidably connected to the outer peripheral wall of the inner threaded sleeve 54 along the axial direction of the inner threaded sleeve 54.

[0056] To achieve selectively driving the number of inner threaded sleeves 54 to rotate through the driving belt ring 61, preferably, the engaging teeth 62 are slidably connected to the outer peripheral wall of the inner threaded sleeve 54 along the axial direction of the inner threaded sleeve 54. The driving mechanism 60 further includes a connecting ring 63 slidably connected to the outside of the inner threaded sleeve 54. The connecting ring 63 is fixedly connected to the engaging teeth 62. An embedding member 621 is fixed to the side of the connecting ring 63 and / or at least one engaging tooth 62 facing the inner threaded sleeve 54. The embedding member 621 extends along the axial direction of the inner threaded sleeve 54. An embedding groove 541 extending along the axial direction is provided on the outer side wall of the inner threaded sleeve 54. The embedding groove 541 extends from the upper end surface of the inner threaded sleeve 54 to the lower end surface of the inner threaded sleeve 54. The embedding member 621 is slidably embedded in the embedding groove 541 along the axial direction of the inner threaded sleeve 54. When the connecting ring 63 moves to the first position, the engaging teeth 62 are engaged with the engaging grooves 611, see Figure 4 ; when the connecting ring 63 moves to the second position, the engaging teeth 62 are located below the engaging grooves 611 and separated from the engaging grooves 611. The second position is located below the first position, see Figure 5 .

[0057] Referring to Figure 4 and Figure 5 , further, a limiting ring 546 is integrally formed on the outer peripheral wall of the inner threaded sleeve 54. The limiting ring 546 is coaxially arranged with the inner threaded sleeve 54. The limiting ring 546 is located in the middle of the inner threaded sleeve 54. The limiting ring 546 abuts against the lower side of the driving belt ring 61 so that the driving belt ring 61 is held above the inner threaded sleeve 54. The connecting ring 63 is located below 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 down with the engaging teeth 62.

[0058] Generally, the road paving is horizontally arranged. However, in some special cases, the road may be paved obliquely, such as on slopes. Especially when the roadbed is not parallel to the road surface and the inclination angle is large, there will be a large deviation or even it cannot be used when using the above technical solution for paving positioning. To cope with the situation where the roadbed is not parallel to the road surface, referring to Figure 6 and Figure 7 , in some examples, the number of the adjusting mechanisms 50 is two. The upper ends of the guide columns 52 of the two adjusting mechanisms 50 are pivotally connected to the lower side of the first cross plate 10, so that the guide columns 52 can swing left and right along the length direction of the first cross plate 10. The lower end of the inner threaded sleeve 54 of one of the adjusting mechanisms 50 is circumferentially rotatably connected to the second cross plate 20, that is, the lower end of the inner threaded sleeve 54 abuts against the upper side of the second cross plate 20. A rotating column 542 is coaxially fixed to the lower end of the inner threaded sleeve 54. The rotating column 542 penetrates through the second cross plate 20 and is rotatably connected to the second cross plate 20. A snap spring 543 is provided at the lower end of the rotating column 542 and abuts against the lower side of the second cross plate 20.

[0059] Referring to Figure 6 , Figure 8 and Figure 9 , the lower end of the inner threaded sleeve 54 of the other adjusting mechanism 50 is circumferentially rotatably connected to the second cross plate 20 and can swing left and right along the length direction of the second cross plate 20, so that the extension lines of the first cross plate 10 and the second cross plate 20 along the length direction can intersect. Specifically, a hinge ball 544 is provided at the lower end of the inner threaded sleeve 54. The hinge ball 544 is connected to the inner threaded sleeve 54 through a connecting column 545. The diameter of the connecting column 545 is smaller than that of the hinge ball 544. The connecting column 545 is welded or integrally formed with the hinge ball 544. The connecting column 545 is coaxially thread-fixed to the lower end of the inner threaded sleeve 54. The second cross plate 20 is provided with a receiving groove 21 for placing and rotating the hinge ball 544. The opening of the receiving groove 21 faces downward, so as to facilitate the installation of the connecting column 545 and the hinge ball 544 into the receiving groove 21 from bottom to top. The second cross plate 20 is provided with a cover plate 24 for covering the receiving groove 21. The cover plate 24 abuts against the hinge ball 544, so that the hinge ball 544 is held in the receiving groove 21. A swinging groove 22 extending along the length direction of the second cross plate 20 is provided on the upper side of the second cross plate 20. The swinging groove 22 communicates with the receiving groove 21. The connecting column 545 passes through the swinging groove 22 and can swing left and right in the swinging groove 22.

[0060] During use, first fix the second cross plate 20 to the roadbed through the anchor rod 30. At this time, the connecting rings 63 of the two driving mechanisms 60 are both in the first position. Use the driving mechanisms 60 to simultaneously drive the rotation of the internally threaded sleeves 54 of the two adjusting mechanisms 50 until one end of the first cross plate 10 reaches the height of the lowest point of the inclined road surface. 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 internally threaded sleeve 54 of the adjusting mechanism 50 far 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.

[0061] The implementation principle of a road paving positioning device according to an embodiment of the present application is as follows: Before road paving, first lay out the lines, and then arrange the road paving positioning device according to the above lines. Fix the second cross plate 20 to the ground through the anchor rod 30, and then adjust the length of the telescopic rod 70 so that the distance between the two relatively arranged first vertical plates 40 is consistent with the preset width of the road surface. Finally, drive the internally threaded sleeve 54 to rotate through the driving mechanism 60 to adjust the distance and / or angle between the first cross plate 10 and the second cross plate 20, so that the upper surface of the first cross plate 10 is consistent with the preset road surface of the road, without the need to reserve an operating surface of 200 mm - 300 mm in the edge area, reducing material waste and facilitating adjustment at the same time. When compacting the road edge, the first vertical plate 40 and the second vertical plate 23 block and limit the edge, making it difficult for the road edge to collapse and be incomplete, improving the construction quality of the road edge.
