Description

Technical Field

[0001] This invention relates to the field of road paving, specifically to a road paving positioning device and a road paving method. Background Technology

[0002] Municipal road paving is a systematic project that encompasses six core aspects: preliminary preparation, foundation construction, surface paving, ancillary works, quality testing, and post-construction maintenance. It must take into account load-bearing capacity, traffic comfort, durability, and environmental protection requirements.

[0003] During the paving process, elevation control is mostly achieved through steel wire rope guidance. The taut steel wire rope (suspension line) is used to mark the road centerline, edge line, or paving elevation to avoid construction deviations. Some simple road paving positioning devices use sliding suspension lines to quickly delineate the paving area. However, in actual paving, the steel wire rope itself is affected by surrounding environmental factors. Wind can cause the suspension line to sway, and temperature changes can cause the cable to expand and contract. Both of these will change the length and position of the suspension line, causing dynamic errors. Therefore, Chinese patent CN119553580B discloses a road paving positioning device and road paving method. The distance between the first and second horizontal plates is adjusted by the threaded connection between the inner and outer threaded sleeves, so that the height of the first horizontal plate is consistent with the preset height of the road surface. Moreover, the adjustment mechanism is located between the first and second horizontal plates and does not come into contact with the road surface material, making it easy to adjust and use.

[0004] In summary, the above-mentioned structure, with its staggered installation of the first and second horizontal plates during actual paving and positioning, results in the first and second vertical plates not being on the same plane. During road paving and compaction, to ensure the stability of the positioning device and prevent deformation, the first and second horizontal plates are typically quite thick. During paver compaction, the material at the edges of the horizontal plates is squeezed, causing them to move to both sides. This results in a stepped shape at the road edge during paving, requiring subsequent repairs and increasing the overall workload. Furthermore, the first and second horizontal plates are supported and limited by anchor bolts and telescopic rods. This support method results in a relatively singular stress distribution, which may cause the first and second horizontal plates to tilt during compaction, thus affecting the overall paving effect. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a road paving positioning device and a road paving method to solve the technical problem that, since the first vertical plate and the second vertical plate are not on the same plane, the edge of the road will have a stepped shape during the paving process, and the support method makes the overall force relatively singular, which may cause the first horizontal plate and the second horizontal plate to tilt during the compaction process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a road paving positioning device, comprising a lower horizontal plate, an upper horizontal plate, and an anchor rod, wherein a first vertical plate and a second vertical plate are respectively connected to one side of the lower horizontal plate and the upper horizontal plate, and the first vertical plate and the second vertical plate are vertically arranged; a threaded sleeve is slidably arranged on the top of the lower horizontal plate, wherein a support rod is hinged to the top of the threaded sleeve; one end of the support rod is hinged to the bottom of the upper horizontal plate, and the support rod itself is inclined between the upper horizontal plate and the lower horizontal plate;

[0007] A sliding plate is provided on one side of the threaded sleeve, and a toothed plate is provided on one side of the sliding plate. A fixed gear is engaged at the top of the toothed plate. A groove is provided on one side of the first vertical plate, and an abutment plate that cooperates with the fixed gear is slidably disposed in the groove in the vertical direction.

[0008] By adopting the above technical solution, the support rod drives the upper horizontal plate to move upward, so that the height of the upper horizontal plate is consistent with the preset height of the road surface. At this time, the first vertical plate, the second vertical plate and the support rod are set in a triangle. By utilizing the non-deformable property of the triangle, the structural anti-lateral stiffness is improved, ensuring that the first vertical plate and the second vertical plate will not tilt during the compaction process. When the upper horizontal plate moves upward to adjust its height through the support rod, its abutment plate will slide upward accordingly, so that the top of the abutment plate and the bottom of the second vertical plate are always in contact. After the adjustment is completed, the abutment plate cooperates with the first vertical plate and the second vertical plate to make their positioning surfaces on the same horizontal plane.

[0009] The invention is further configured such that threaded rods are symmetrically rotatably arranged on the lower horizontal plate, wherein two sets of threaded rods are connected by a first transmission mechanism, and the threaded rods are used to drive the threaded sleeve to slide on the top of the lower horizontal plate.

[0010] Preferably, when the operator rotates the threaded rod, the other set of threaded rods rotates synchronously under the action of the first transmission mechanism, ensuring that when the subsequent support rod adjusts the upper horizontal plate, the upper horizontal plate slides vertically, preventing tilting during the adjustment process.

[0011] The present invention is further configured such that an adjusting column is elastically slidably disposed inside the anchor rod, wherein the bottom end of the adjusting column is arc-shaped and a guide column is disposed at the top of the adjusting column; the bottom of the sliding plate is provided with an irregularly shaped groove for the guide column to slide vertically; and the outer wall of the anchor rod is elastically provided with an array of piercing components that cooperate with the adjusting column.

[0012] Preferably, during the movement of the sliding plate, its irregular groove will squeeze the guide column at the top of the adjusting column, causing the adjusting column to move downward. During this process, the adjusting column itself squeezes the piercing component to slide outward and the anchor rod, completing the lateral piercing work of the piercing component, increasing the lateral contact area of ​​the anchor rod in the ground, improving the overall stability of the device when facing the compaction work of the paver on the edge, and effectively preventing its positional displacement.

[0013] The present invention is further configured such that a second transmission mechanism is connected to one side of the fixed gear, an adjusting gear is connected to one side of the second transmission mechanism, and an array of tooth blocks that mesh with the adjusting gear are provided on one side of the abutment plate.

[0014] Preferably, during the rotation of the fixed gear under the action of the toothed plate, it drives the second transmission mechanism on one side to rotate. During this process, the second transmission mechanism drives the adjusting gear to rotate. Through the meshing of the adjusting gear and the toothed block, the fixed gear drives the abutment plate in the groove to slide vertically when it rotates.

[0015] The present invention is further configured such that a telescopic mechanism is provided between the lower horizontal plate and the upper horizontal plate.

[0016] Preferably, the upper and lower horizontal plates are kept connected by the telescopic mechanism to ensure the stability of their fit.

[0017] The present invention is further configured such that both the first transmission mechanism and the second transmission mechanism include a driving sprocket, a transmission chain and a driven sprocket, wherein the driving sprocket and the driven sprocket are connected by a transmission chain.

[0018] Preferably, the two sets of threaded rods and adjusting gears can rotate synchronously under the action of the driving sprocket and the driven sprocket, and the sprocket and chain can effectively prevent slippage during transmission.

[0019] The invention is further configured such that a limiting groove is provided on the lower horizontal plate for the threaded sleeve to slide, wherein the threaded sleeve itself is located inside the limiting groove.

[0020] Preferably, by setting the limiting groove, the threaded sleeve can be effectively prevented from rotating along with the threaded rod during rotation, thus ensuring the stability of the threaded sleeve sliding at the top of the lower horizontal plate.

[0021] The present invention is further configured such that one end of both the guide post and the puncture component is provided with an arc-shaped end face, and the arc-shaped end face is provided in a smooth manner.

[0022] Preferably, the arc-shaped end face can stably engage with the protrusion in the irregular groove during the sliding of the guide post, and at the same time, when the adjusting post slides down, it is easy to squeeze the puncture component, so that the puncture component slides outward.

[0023] The present invention is further configured such that one end of the threaded rod is provided with a rocker arm, and the outer wall of the rocker arm is provided with an array of micro protrusions.

[0024] Preferably, the rocker arm facilitates the rotation of the threaded rod by the operator, and the micro-protrusions on the outer wall of the rocker arm increase the sliding friction between the operator's hand and the rocker arm.

[0025] A road paving method includes the following steps:

[0026] Step 1: Lay out lines along both sides of the road. Then, the staff places the lower horizontal board along the projection of the lines on the ground and uses the anchor rods at the bottom of the lower horizontal board to limit its position.

[0027] Step 2: According to the height of the road paving, the staff rotates the threaded rod, which causes the threaded sleeve to move the support rod. During this process, the support rod lifts the upper horizontal plate upward, so that the height of the upper horizontal plate is consistent with the preset height of the road surface. As the threaded sleeve drives the sliding plate to slide, the piercing part pushes out the anchor rod through the irregular groove and the adjusting column, increasing the contact area between the anchor rod and the ground in the horizontal direction.

[0028] Step 3: Use a paver to spread the material between the road paving positioning devices on both sides of the road. The elevation control sensor of the paver is used as the standard for the upper horizontal plate. After the material is laid, use a road roller to compact the road surface.

[0029] By adopting the above technical solution, it is ensured that the first and second vertical plates will not tilt during the compaction process, which improves the overall laying stability. Furthermore, after the laying is completed, there is no need for workers to repair the edges, thus reducing the overall workload.

[0030] In summary, the present invention has the following main beneficial effects:

[0031] In this invention, the upper and lower horizontal plates are hinged together by a support rod. When the threaded rod rotates, the threaded sleeve will drive the support rod to move to one side, causing the support rod to move the upper horizontal plate upward. During this process, the height of the upper horizontal plate is made consistent with the preset height of the road surface. At this time, the first vertical plate, the second vertical plate and the support rod are arranged in a triangle. By utilizing the non-deformable property of the triangle, the lateral stiffness of the structure is improved, ensuring that the first vertical plate and the second vertical plate will not tilt during the compaction process, thereby improving the overall paving stability.

[0032] This invention features a sliding plate at the bottom of a threaded sleeve, with a toothed plate at the top. As the threaded sleeve pushes the support rod to move, the toothed plate drives a fixed gear to rotate. Under the action of the transmission mechanism, the abutment plate inside the first vertical plate slides upward. During this process, when the upper horizontal plate moves upward to adjust its height via the support rod, its abutment plate slides upward as well, ensuring that the top of the abutment plate is always in contact with the bottom of the second vertical plate. After adjustment, the abutment plate, in conjunction with the first and second vertical plates, ensures that their positioning surfaces are on the same horizontal plane. After installation, no further edge repairs are required, reducing the overall workload.

[0033] This invention features an anchor rod at the bottom of the lower horizontal plate, with an adjusting column elastically sliding inside the anchor rod. The sliding plate has a shaped groove. As the sliding plate moves, the groove presses against the guide column at the top of the adjusting column, causing the adjusting column to move downwards. During this process, the adjusting column itself presses against the piercing component, which slides outwards from the anchor rod, completing the lateral piercing work. This increases the lateral contact area of ​​the anchor rod underground, improving the overall stability of the device when facing the compaction work of the paver at the edge and effectively preventing positional displacement.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0050] The embodiments of the present invention will now be described.

[0051] Example 1: Please refer to Figures 1-11 The road paving positioning device and road paving method shown include a lower horizontal plate 1, an upper horizontal plate 2, a telescopic mechanism 3, a support mechanism, an adjustment mechanism and a sliding mechanism. A first vertical plate 8 and a second vertical plate 9 are respectively connected to one side of the lower horizontal plate 1 and the upper horizontal plate 2, and the first vertical plate 8 and the second vertical plate 9 are vertically arranged. At the same time, a telescopic mechanism 3 is provided between the lower horizontal plate 1 and the upper horizontal plate 2. Under the action of the telescopic mechanism 3, the upper horizontal plate 2 and the lower horizontal plate 1 are always connected. Then, the device is fixed to the two sides of the road by the anchor rod 4 at the bottom of the lower horizontal plate 1.

[0052] The lower horizontal plate 1 is symmetrically equipped with threaded rods 6, and the two sets of threaded rods 6 are connected by a first transmission mechanism 5. The threaded rods 6 are used to drive the threaded sleeve 10 to slide on the top of the lower horizontal plate 1. When the worker rotates the threaded rods 6, the other set of threaded rods 6 rotates synchronously under the action of the first transmission mechanism 5, thereby driving the threaded sleeve 10 to slide. Since the top of the threaded sleeve 10 is hinged to a support rod 7, one end of the support rod 7 is hinged to the bottom of the upper horizontal plate 2. During the sliding process of the threaded sleeve 10, the support rod 7 will lift the upper horizontal plate 2, so that the height of the upper horizontal plate 2 is consistent with the preset height of the road surface. The support rod 7 itself is inclined between the upper horizontal plate 2 and the lower horizontal plate 1. At this time, the first vertical plate 8, the second vertical plate 9 and the support rod 7 are arranged in a triangle. By utilizing the non-deformable property of the triangle, the structural anti-lateral stiffness is improved, ensuring that the first vertical plate 8 and the second vertical plate 9 will not tilt during the compaction process.

[0053] Meanwhile, a sliding plate 13 is provided on one side of the threaded sleeve 10, and a toothed plate 14 is provided on one side of the sliding plate 13. A fixed gear 15 is meshed at the top of the toothed plate 14. When the threaded sleeve 10 slides under the action of the threaded rod 6, the sliding plate 13 will drive the toothed plate 14 to move, thereby driving the fixed gear 15 to rotate. Since a second transmission mechanism 16 is connected to one side of the fixed gear 15, and an adjusting gear 17 is connected to one side of the second transmission mechanism 16, during the rotation of the fixed gear 15 under the action of the toothed plate 14... This will drive the second transmission mechanism 16 on one side to rotate. During this process, the second transmission mechanism 16 drives the adjusting gear 17 to rotate. A groove 20 is provided on one side of the first vertical plate 8. A contact plate 19 that cooperates with the adjusting gear 17 is slidably arranged in the groove 20 in the vertical direction. A set of tooth blocks 18 that mesh with the adjusting gear 17 are provided on one side of the contact plate 19. Through the meshing of the adjusting gear 17 and the tooth blocks 18, when the fixed gear 15 rotates, it will drive the contact plate 19 in the groove 20 to slide in the vertical direction.

[0054] This ensures that the top of the abutment plate 19 and the bottom of the second vertical plate 9 are always in contact. After adjustment, the abutment plate 19, in conjunction with the first vertical plate 8 and the second vertical plate 9, ensures that the distance between the groove 20 and the edge of the first vertical plate 8 is 1 cm. Therefore, the distance between the abutment plate 19 and the first vertical plate 8 is negligible during the lifting process, so that the positioning surfaces of the abutment plate 19, the first vertical plate 8 and the second vertical plate 9 are on the same horizontal plane. After the subsequent paving is completed by the paver, the road surface is compacted by the roller without the need for subsequent repairs to the edges, thus reducing the overall workload.

[0055] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 6The first transmission mechanism 5 and the second transmission mechanism 16 both include a driving sprocket, a transmission chain and a driven sprocket. The driving sprocket and the driven sprocket are connected by a transmission chain. Under the action of the driving sprocket and the driven sprocket, the two sets of threaded rods 6 and the adjusting gear 17 can rotate synchronously. Under the action of the sprocket and the chain, slippage during transmission is effectively prevented, further ensuring the synchronization of the overall transmission.

[0056] Example 2: Please refer to Figure 8 , Figure 9 and Figure 10 The road paving positioning device and road paving method shown are similar in overall structure to Embodiment 1. An adjusting column 12 is elastically slidably installed inside the anchor rod 4. A guide column 21 is installed at the top of the adjusting column 12. A shaped groove 22 is provided at the bottom of the sliding plate 13 for the guide column 21 to slide vertically. An array of piercing components 11 that cooperate with the adjusting column 12 are elastically installed on the outer wall of the anchor rod 4. During the movement of the sliding plate 13, the shaped groove 22 presses against the guide column 21 at the top of the adjusting column 12, causing the adjusting column 12 to move downwards. Since the bottom end of the adjusting column 12 is arc-shaped, the adjusting column 12 itself presses against the piercing components 11, sliding them outwards from the anchor rod 4, completing the lateral piercing work of the piercing components 11. This increases the lateral contact area of ​​the anchor rod 4 underground, improving the overall stability of the device when facing the compaction work of the paver at the edge, and effectively preventing positional displacement.

[0057] Example 3: Please refer to Figure 12 and Figure 13 The road paving positioning device and road paving method shown herein, based on Embodiment 2, wherein the telescopic mechanism 3 includes a top plate 301, an elastic airbag 302, and a top rod 303. The bottom of the top rod 303 is connected to the top plate 301, and the elastic airbag 302 is wrapped around the outer wall of the top rod 303. When the top rod 303 cooperates with the top plate 301 to lift, the elastic airbag 302 on its outer wall is compressed, and the gas inside the elastic airbag 302 is compressed and discharged. At the same time, the second vertical plate 9 is provided with an airbag groove 23 for the abutment plate 19 to be inserted into. Furthermore, the air bladder groove 23 is connected to the elastic air bladder 302, facilitating the insertion of the abutment plate 19 and ensuring stability between the first vertical plate 8 and the second vertical plate 9. The gas inside the elastic air bladder 302 is released into the air bladder groove 23, which contains an air bladder plate. In this state, the air bladder plate is inflated through the elastic air bladder 302, fully filling the gap between the abutment plate 19 and the air bladder groove 23. This ensures that impurities do not enter the air bladder groove 23 during paver operation, improving overall paving efficiency.

[0058] In practical operation, the invention is used by placing the lower horizontal plate 1 on both sides of the road and installing the entire device on the road edge using anchor rods 4. The operator rotates a rocker arm to rotate the threaded rod 6 on the lower horizontal plate 1, which in turn causes the threaded sleeve 10 to slide. Since the upper horizontal plate 2 and the threaded sleeve 10 are hinged together by a support rod 7, the sliding of the threaded sleeve 10, in conjunction with the top support rod 7, allows for height adjustment of the upper horizontal plate 2, ensuring its height matches the preset height of the road surface. The first vertical plate 8, the second vertical plate 9, and the support rod 7 form a triangle, utilizing the non-deformable nature of triangles to enhance the structural lateral stiffness and prevent tilting of the first and second vertical plates during compaction, thus improving overall paving stability.

[0059] Meanwhile, a sliding plate 13 is provided on one side of the threaded sleeve 10. The sliding plate 13 can slide on the lower horizontal plate 1. Since the sliding plate 13 is provided with a toothed plate 14, the fixed gear 15 is driven to rotate through the toothed plate 14 during the sliding process. Under the action of the transmission component, the adjusting gear 17 is rotated. Since an array of toothed blocks 18 that mesh with the adjusting gear 17 are provided on one side of the abutment plate 19, during the height adjustment of the upper horizontal plate 2, the adjusting gear 17 will drive the abutment plate 19 to slide upward through the toothed blocks 18. When the upper horizontal plate 2 drives the second vertical plate 9 to slide, the top of the abutment plate 19 will always be in contact with the bottom of the second vertical plate 9. After the adjustment is completed, the abutment plate 19 cooperates with the first vertical plate 8 and the second vertical plate 9 to make their positioning surfaces on the same horizontal plane. After the laying is completed, no workers are required to repair its edges.

[0060] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
