Description

Technical Field

[0001] This invention relates to the field of highway engineering construction technology, specifically to a formwork-free paving aid for road compaction edges and its application. Background Technology

[0002] In traditional road construction, paving is done first, followed by compaction. During both paving and compaction, formwork is installed according to the roadbed design alignment. The formwork is made of timber or channel steel and secured with steel stakes to prevent displacement and deformation during paver and roller operation. Traditional road compaction methods require a large number of formworks, including long wooden timbers or steel channel steels. Timber is easily damaged, and channel steel is expensive. The labor intensity of handling and installation is high, resulting in low work efficiency and difficulty in ensuring alignment and neat edges. Furthermore, the width of the timber or channel steel itself occupies space due to the formwork erection, requiring an extension of the roadbed width, leading to significant waste and increased project costs. Additionally, the large number of workers involved in on-site formwork removal, vehicle transportation, and roller compaction creates a chaotic and potentially dangerous work environment. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a formwork-free construction aid for road compaction edges and its application. This formwork-free construction aid for road compaction edges can adapt to the compaction work of slopes and curved roads, thereby improving the road compaction efficiency. It can be applied to road roller equipment to improve the convenience and safety of equipment use.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A road compaction edge-free paving aid device, comprising:

[0006] The system includes: a roller frame; two templates, one on each side of the roller frame; a compaction mechanism comprising a first template posture adjustment component and a second template posture adjustment component, which connect the templates to the roller frame; and a compaction control system that adjusts the height of the templates perpendicular to the road surface using the first template posture adjustment component and adjusts the position of the template ends in the road width direction or the height difference between the template ends using the second template posture adjustment component. The first and second template posture adjustment components are linked together.

[0007] Furthermore, the first template posture adjustment assembly is provided with a set, which includes two vertically arranged first telescopic hydraulic cylinders. The telescopic rods of the two first telescopic hydraulic cylinders are respectively hinged to the middle of the top surface of the two templates, and the cylinders of the two first telescopic hydraulic cylinders are respectively hinged to both sides of the roller frame.

[0008] Furthermore, the inner wall of the template is a pressing surface. There are two sets of second template posture adjustment components, which correspond to the two templates respectively. The second template posture adjustment components include two second telescopic cylinders. The telescopic rods of the two second telescopic cylinders are respectively hinged to the top two ends of the corresponding pressing surface. The cylinders of the two second telescopic cylinders are both hinged to the bottom of the rolling mill frame.

[0009] Furthermore, the compaction control system includes a fully hydraulic steering gear, a steering cylinder, a gear pump, a lifting control valve, a shuttle valve, and a hydraulically controlled check valve. The steering cylinder and the gear pump are both connected to the fully hydraulic steering gear. The first telescopic cylinder and the gear pump are connected through the lifting control valve. The first telescopic cylinder and the steering cylinder are connected through the shuttle valve. The rodless chamber of the first telescopic cylinder is connected to the oil tank through the hydraulically controlled check valve. The rod chambers of the second telescopic cylinders at both ends of the template are connected to the first hydraulic telescopic rod in the middle of the template.

[0010] Furthermore, both the rodless chamber of the first telescopic cylinder and the rodless chamber of the second telescopic cylinder are connected to an accumulator.

[0011] Furthermore, arc-shaped transition surfaces are provided between both ends of the template and the pressing surface.

[0012] Furthermore, the longitudinal sections at both ends of the template are triangular or trapezoidal.

[0013] Furthermore, several vibrators are provided on the outside of the template.

[0014] Furthermore, the present invention also provides an application of the above-mentioned road compaction edge formwork-free paving aid device in a road roller.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This invention, through the setting of a template, a first template posture adjustment component, and a second template posture adjustment component, and by controlling the extension or retraction of the first telescopic cylinder in the middle of the template, can adjust the height of the template in the direction perpendicular to the road surface. By controlling the extension or retraction of the second telescopic cylinders at both ends of the template, can adjust the position of the template in the road width direction or adjust the height difference between the two ends of the template, thus providing convenience for edge compaction of roads with different slopes and curved roads, and improving the construction quality of road edge compaction.

[0017] 2. By setting up a roller frame and a compaction control system, this invention can apply the formwork-free construction auxiliary device for the entire road compaction edge to a road roller, thereby enabling automatic adjustment of the height and position of the formwork when the road roller turns, preventing the formwork from damaging or affecting the already compacted road surface, and preventing the formwork from hitting the curb, road guardrail, or other construction equipment and personnel, thus improving the convenience and safety of equipment use.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "configure," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figure 1-6 As shown, this embodiment provides a formwork-free paving aid for road edge compaction, which can be applied to road rollers for compaction operations on road edges. It includes a roller frame 13, templates 1, a compaction mechanism, and a compaction control system. Two templates 1 are provided, one on each side of the roller frame 13. The compaction mechanism includes a first template posture adjustment component and a second template posture adjustment component, which connect the templates 1 and the roller frame 13. The compaction control system can adjust the height of the templates 1 perpendicular to the road surface by controlling the first template posture adjustment component, and can adjust the position of the templates 1 in the road width direction or the height difference between the two ends of the templates 1 by controlling the second template posture adjustment component. The first and second template posture adjustment components can also be linked.

[0032] like Figure 2 , 3 As shown in Figure 6, template 1 is a long strip of board. The inner wall of template 1 is the pressing surface 10. During the compaction operation, the pressing surface 10 of template 1 comes into contact with the compacted edge of the road, and the compacted edge of the road is compacted by the pressing surface 10.

[0033] like Figure 1 , 2As shown in Figure 6, the first template posture adjustment assembly includes two vertically arranged first telescopic cylinders 2. Specifically, the telescopic rods of the two first telescopic cylinders 2 are respectively hinged to the middle of the top surface of the two templates 1. By controlling the extension or retraction of the first telescopic cylinders 2 through the compaction control system, the height of the template 1 in the direction perpendicular to the road surface can be adjusted. When the template 1 is not in use, the first telescopic cylinders 2 can be retracted through the compaction control system, thereby raising the template 1 and preventing the template 1 from colliding with other objects.

[0034] like Figure 1 , 2 As shown in Figure 6, the second template posture adjustment assembly has two sets, and each set corresponds to one of the two templates. Specifically, the second template posture adjustment assembly includes two second telescopic cylinders 3, and the telescopic rods of the two second telescopic cylinders 3 are respectively hinged to the top of the corresponding pressing surface 10. The cylinder barrels of the two second telescopic cylinders are both hinged to the bottom of the roller frame 13, so that the second telescopic cylinders 3 are in the following position: Figure 6 The template 1 is tilted or positioned along the width of the road. The second telescopic cylinder 3 is extended or retracted by the compaction control system, allowing adjustment of the template 1's position along the road width. Specifically, when the second telescopic cylinder 3 at both ends of the template extends or retracts by different lengths, the difference in position between the front and rear ends of the template 1 along the road width causes the template 1 to tilt relative to the road length, thus turning the template 1. This makes it better suited for edge compaction work on roads with sharp turns. Simultaneously, the extension or retraction of the second telescopic cylinder 3 also results in different heights of the template 1 at both ends relative to the ground, allowing adjustment of the height difference between the two ends of the template 1. This makes it better suited for edge compaction work on roads with different slopes.

[0035] like Figure 4 As shown, the compaction control system includes a fully hydraulic steering gear 5, a steering cylinder 6, a gear pump 7, a lifting operating valve 8, a shuttle valve 9, and a hydraulically controlled check valve 12. The steering cylinder 6 and gear pump 7 are both connected to the fully hydraulic steering gear 5. The fully hydraulic steering gear 5, steering cylinder 6, and gear pump 7 form a steering hydraulic system used on the road roller. The gear pump 7 supplies oil to the system, and the hydraulic oil is supplied to the steering cylinder 6 through the fully hydraulic steering gear 5. The operator turns the fully hydraulic steering gear 5 to steer the road roller.

[0036] In order to realize the extension and retraction control of the first telescopic cylinder 2 and the second telescopic cylinder 3 by the compaction control system and to realize the linkage between the first telescopic cylinder 2 and the second telescopic cylinder 3, the first telescopic cylinder 2 and the gear pump 7 are connected through the lifting operation valve 8, the first telescopic cylinder 2 and the steering cylinder 6 are connected through the shuttle valve 9, and the rodless chamber of the first telescopic cylinder 2 is connected to the oil tank of the road roller through the hydraulic control check valve 12. In addition, for the first telescopic cylinder 2 and the second telescopic cylinder 3 on the same template 1, the rod chambers of the second telescopic cylinder 3 at both ends of the template 1 are connected to the first hydraulic telescopic rod 2 in the middle of the template 1.

[0037] Based on the connection between the first telescopic cylinder 2, the second telescopic cylinder 3, and the compaction control system, the first telescopic cylinder 2 has two fluid supply methods: one is connected to the gear pump 7 through the lifting operation valve 8. At the start and end of the operation, the lifting operation valve 8 can be manually operated to provide power to the first hydraulic telescopic rod 2, thereby realizing the lowering and raising of the template 1; the other is connected to the steering cylinder 6 through the shuttle valve (9). When there is hydraulic oil in one of the two oil circuits of the steering cylinder 6, its pressure opens the shuttle valve 9 to provide power to the first hydraulic telescopic rod 2, thereby automatically realizing the raising of the template 1. That is, when there is a steering action, the template 1 needs to be raised to avoid damaging the compacted road surface during the steering. At the same time, the rodless chamber of the first telescopic cylinder 2 is connected to the oil tank of the road roller through the hydraulic control check valve 12, which facilitates the return of oil from the rodless chamber of the first hydraulic telescopic rod 2. The rod chambers of the second telescopic cylinders 3 at both ends of the template 1 are connected to the first hydraulic telescopic rod 2 in the middle of the template 1, so that the three telescopic cylinders on the same template 1 can be linked when the template 1 is raised and turned.

[0038] To further ensure safe use, such as Figure 4 As shown, the rodless chamber of the first telescopic cylinder 2 and the rodless chamber of the second telescopic cylinder 3 are both connected to the accumulator 14. In this way, when the road surface has a longitudinal slope, the accumulator 14 can ensure that the template 1 has a buffering effect, so that the template 1 can move with the undulation of the road surface, that is, to keep the template 1 in contact with the compacted surface and to ensure that the template 1 is not damaged due to changes in hydraulic oil pressure.

[0039] like Figure 1 , 2 As shown, several vibrators 4 are installed on the outside of the template 1, which enable the template 1 to better compact the road edge.

[0040] like Figure 3 As shown, the thickness of the template 1 gradually decreases at both ends, so that the two ends of the template 1 and the pressing surface 10 form an arc-shaped transition surface 11. The arc-shaped transition surface 11 can reduce the resistance of the template 1 and has the effect of gradually gathering and compacting the road compaction edge material.

[0041] like Figure 1As shown, the longitudinal sections at both ends of template 1 are triangular or trapezoidal, which can reduce travel resistance.

[0042] like Figure 5 , 6 As shown, this embodiment of the road compaction edge formwork-free paving aid device is applied in a road roller. The fully hydraulic steering gear 5, steering cylinder 6, and gear pump 7 constitute the road roller's steering hydraulic system. The first telescopic cylinder 2 and the second telescopic cylinder 3 are hinged and installed on the roller frame 13 of the road roller. During road compaction, the road roller moves along one side of the road, and the roller compacts the road. At the same time, the pressing surface 10 of the template 1 contacts the compacted edge of the road, realizing the compaction of the road edge. When it is necessary to adjust the template 1, the height of the template 1 in the direction perpendicular to the road surface can be adjusted by controlling the extension or shortening of the first telescopic cylinder 2 in the middle of the template 1. By controlling the extension or shortening of the second telescopic cylinders 3 at both ends of the template 1, the position of the template 1 in the road width direction or the height difference between the two ends of the template can be adjusted. This provides convenience for edge compaction of roads with different slopes and curves, and improves the construction quality of road edge compaction.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
