Description

Technical Field

[0001] This utility model relates to the technical field of asphalt paving auxiliary facilities, specifically to a rapid leveling device for asphalt paving joints. Background Technology

[0002] In asphalt paving construction, the treatment of joints between new and old road surfaces and longitudinal cold joints is a key challenge. The axial flatness of these joints directly affects the durability and waterproofing performance of the road surface. Traditional techniques generally use two methods: manual leveling or testing with equipment. Workers manually level the joints along the axial direction of the road with shovels, rakes, and scrapers, but this method is inefficient and easily affected by the operator's skill level. Joints are prone to unevenness and large height differences, which can easily lead to vehicle bouncing later on. Manual shoveling and repair can also cause asphalt mixture to scatter and pollute the environment. Adding infrared sensors to pavers is costly and complicated, making it difficult to promote in small and medium-sized construction sites. Utility Model Content

[0003] This application provides a rapid leveling device for asphalt paving joints, which can solve the technical problems in the prior art where manual leveling of the joints between new and old asphalt paving roads leads to low efficiency and unstable leveling results, and large height differences are likely to occur at the joints. Adding a sensing device to the paver would result in high costs and complicated procedures.

[0004] This application provides a rapid leveling device for asphalt paving joints, comprising:

[0005] A compaction assembly, comprising a support plate and a rolling wheel and a guide wheel located at the bottom of the support plate, wherein the rolling wheel and the guide wheel are arranged at intervals on both sides of the support plate along a first direction, the first direction being the width direction of the road to be leveled;

[0006] The leveling assembly includes a shuttle-shaped scraper inclinedly disposed between the compaction wheel and the guide wheel. One end of the shuttle-shaped scraper is elastically hinged to the bottom of the support plate, and the bottom of the other end is used to abut against the road joint to be leveled. The connection end between the shuttle-shaped scraper and the support plate is provided with a height adjustment component, and the shuttle-shaped scraper is located in front of the compaction wheel in a second direction, which is the direction of advancement along the axial direction of the road joint to be leveled.

[0007] In one embodiment, a water spraying assembly is provided on the top of the support plate, the water spraying assembly including a water tank located above the rolling wheel and a water spray nozzle communicating with the water tank.

[0008] In one embodiment, the water tank is further provided with an inlet and an outlet pipe, the outlet pipe passing through the support plate and extending to the bottom surface of the support plate.

[0009] In one embodiment, the water nozzle is connected to the water outlet pipe and faces the rolling mill, and there are multiple water nozzles, which are spaced apart along the axial direction of the rolling mill.

[0010] In one embodiment, the top of the support plate is provided with a connecting component for connecting an external paver. The connecting component includes a longitudinally arranged connecting rod, and the bottom of the connecting rod is detachably connected to the support plate.

[0011] In one embodiment, the height adjustment member includes a longitudinally arranged adjustment screw, and the support plate has a through hole for the adjustment screw to pass through.

[0012] In one embodiment, the bottom of the adjusting screw passes through the through hole and is connected to the shuttle-shaped scraper, and the top of the adjusting screw is provided with a rotating handle.

[0016] The beneficial effects of the technical solutions provided in this application include:

[0017] 1. By setting a shuttle-shaped scraper between the compaction wheel and the guide wheel, the shuttle-shaped scraper first contacts the joint of the road to be leveled, and then the compaction wheel passes through. The shuttle-shaped scraper can simultaneously perform a combined action of lateral leveling and axial advancement to ensure the lateral and axial flatness of the road to be leveled at the same time. Then the compaction wheel compacts the road. The two processes can be completed almost simultaneously, which can save a lot of time for manual paving and also ensure the leveling quality.

[0018] 2. The overall structure is simple, the manufacturing cost is low, and it is easy to maintain later, making it more economical and reducing the capital investment for small construction sites.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0026] This application provides a rapid leveling device for asphalt paving joints, which can solve the technical problems in the prior art where manual leveling of the joints between new and old asphalt paving roads leads to low efficiency and unstable leveling results, and large differences in axial height at the joints. Adding a sensing device to the paver would result in high costs and complicated procedures.

[0027] The rapid asphalt paving joint leveling device in this application includes a compaction component and a leveling component. The leveling component is located below the compaction component and in front of the compaction component. That is, during the leveling process, the leveling device moves along the axial direction of the road to be leveled. The leveling component first contacts the road joint to be leveled to scrape the asphalt in the raised part of the road joint to the concave part. Then the compaction component passes through the road joint to be leveled and compacts it.

[0028] Figure 1 This is a schematic diagram of a rapid leveling device for asphalt paving joints provided in this application, as shown below. Figure 1 As shown, the compaction assembly includes a support plate 1 and a rolling wheel 2 and a guide wheel 3 located at the bottom of the support plate 1. The rolling wheel 2 and the guide wheel 3 are arranged at intervals on both sides of the support plate 1 along a first direction, which is the width direction of the road to be leveled.

[0029] The support plate 1 is the main load-bearing component of the overall structure. It is a horizontally arranged plate structure. The support plate 1 is preferably made of wear-resistant metal material. While ensuring its load-bearing capacity and resistance to deformation, its own weight can increase the overall self-weight of the structure and improve the compaction effect. When the assembly is completed, the support plate 1 spans the road to be leveled. It should be noted that the road to be leveled in the whole text refers to the road that has been paved and is a combination of new and old roads. This will not be explained again later.

[0030] The compaction wheel 2 and the guide wheel 3 are also arranged in parallel along the first direction on both sides of the bottom of the support plate 1 and along the road width direction. They travel along the axial direction of the road to be leveled. The compaction wheel 2 travels along the joint of the road to be leveled to apply vertical pressure to the asphalt at the joint to improve the material density. The guide wheel 3 and the compaction wheel 2 work together to maintain the stability of the equipment and prevent lateral deviation.

[0031] In one possible implementation, the compaction wheel 2 has a larger diameter, which reduces the ground pressure and the risk of sinking into soft soil. It also increases the coverage area of ​​a single compaction pass and reduces material displacement through a gentler curvature. The guide wheel 3 has a smaller diameter, which ensures improved steering sensitivity and reduced travel resistance.

[0032] Furthermore, the leveling component includes a shuttle-shaped scraper 4 inclined between the compaction wheel 2 and the guide wheel 3. The shuttle-shaped scraper 4 has sharp ends and an arc-shaped protrusion in the middle. One end is elastically hinged to the bottom of the support plate 1, and the bottom of the other end is used to hold the joint of the road to be leveled. Through the inclined shuttle-shaped structure, the road material is naturally spread laterally, and the excess asphalt accumulated on the side of the compaction wheel 2 is forcibly scraped to the concave area on the side of the guide wheel 3. That is, when moving along the axial direction of the road to be leveled, the shuttle-shaped scraper 4 simultaneously performs a combined action of lateral leveling and axial advancement to ensure the lateral and axial flatness of the road to be leveled at the same time.

[0033] Meanwhile, the elastic hinge between the shuttle-shaped scraper 4 and the support plate 1 allows one end of the shuttle-shaped scraper 4 to rotate around the connection point with the support plate 1, while the other end can be elastically adjusted up and down by a certain range, adapting to road surface undulations. In one possible implementation, the vertical floating range of the shuttle-shaped scraper 4 is ±3cm. The shuttle-shaped scraper 4 is located at the front end of the compaction wheel 2 in a second direction, which is the direction of advancement along the axial direction of the road joint to be leveled. After the shuttle-shaped scraper 4 levels the surface, the compaction wheel 2 follows behind to compact it. A height adjustment component 5 is provided at the connection end between the shuttle-shaped scraper 4 and the support plate 1. The height adjustment component 5 can adjust the horizontal height of the shuttle-shaped scraper 4. Combined with the elastic hinge, this further improves the adaptability of the shuttle-shaped scraper 4 to different road conditions.

[0034] In one possible implementation, the shuttle-shaped scraper 4 is made of stainless steel, with an axial length preferably of 10 to 20 cm, and the surface of the shuttle-shaped scraper 4 is coated with a Teflon anti-stick layer.

[0035] Furthermore, the top of the support plate 1 is equipped with a water spraying component 6, which is located directly above the compaction wheel 2. It can spray the surface of the compaction wheel 2 to keep it moist, prevent asphalt from sticking during the movement, and wash away the asphalt that has stuck on the compaction wheel 2 to a certain extent. At the same time, the water spraying component 6 can also increase the weight on one side of the compaction wheel 2 and improve the compaction efficiency.

[0036] Specifically, Figure 2 This is a schematic diagram of the water spraying component 6 in a rapid leveling device for asphalt paving joints provided in this application. Figure 2 As shown, the water spray assembly 6 includes a water tank 601 located above the roller 2. The water tank 601 is also provided with an inlet 603 and an outlet pipe 604. In one possible embodiment, the inlet 603 is located above the top or side wall of the water tank 601 to facilitate water filling. The outlet pipe 604 is located at the bottom of the side wall of the water tank 601 to ensure the outflow water pressure by relying on the weight of the sprayed water in the water tank 601, ensuring that all sprayed water can be discharged by gravity. At the same time, the pressure gradually decreases as the liquid level decreases, which can also indirectly indicate the remaining amount of sprayed water in the water tank 601.

[0037] The water outlet pipe 604 passes through the support plate 1 and extends to the bottom surface of the support plate 1. Several water spray nozzles 602 are provided at the outlet end of the water outlet pipe 604. The water spray nozzles 602 are located above the rolling wheel 2 and face the rolling wheel 2. In one possible embodiment, there are multiple water spray nozzles 602, and the multiple water spray nozzles 602 are spaced apart along the axial direction of the rolling wheel 2 to ensure that the rolling wheel 2 is fully wetted and rinsed.

[0038] Further, see Figure 1The top of the support plate 1 is provided with a connecting component for connecting an external paver. The asphalt paving joint quick leveling device in this application is used to connect the tail of the external paver, using the paver as the driving force, without the need for an additional power source, and can immediately level and compact after following the paver, thus improving efficiency.

[0039] Specifically, the connecting component includes a longitudinally arranged connecting rod 7, and the bottom of the connecting rod 7 is detachably connected to the support plate 1. In one possible embodiment, a C-shaped buckle is provided at the bottom of the connecting rod 7, and an annular groove is opened at the corresponding position of the support plate 1. The C-shaped buckle is inserted into the annular groove by elastic deformation, and the axial fixing force is provided by the rebound force. The C-shaped buckle is a commonly used fastener, and will not be described in detail here.

[0040] Furthermore, Figure 3 This application provides a schematic diagram of the height adjustment component 5 in a rapid leveling device for asphalt paving joints. Figure 3 As shown, the height adjustment component 5 includes a longitudinally arranged adjusting screw 501. A through hole is provided on the support plate 1 for the adjusting screw 501 to pass through. Relative displacement occurs between the adjusting screw 501 and the support plate 1, causing the shuttle-shaped scraper 4 to rise or fall. In one possible embodiment, the adjusting screw 501 is adjusted by a threaded mechanism, meaning a nut is rotatably installed inside the through hole. When the nut is rotated, the adjusting screw 501 undergoes synchronous longitudinal displacement. Of course, the adjusting screw 501 can also employ any longitudinal displacement method found in the prior art; no specific limitation is made in this application. A rotating handle 502 is provided at the top of the adjusting screw 501 to prevent synchronous rotation of the adjusting screw 501 during longitudinal displacement.

[0041] Further, see Figure 3 The bottom of the adjusting screw 501 passes through the through hole and connects to the shuttle-shaped scraper 4. A spring hinge 8 is provided at the connection between the adjusting screw 501 and the shuttle-shaped scraper 4. One side of the spring hinge 8 is connected to the shuttle-shaped scraper 4, and the other side is connected to the bottom of the adjusting screw 501. The spring hinge 8 has a built-in spring, which stores energy by utilizing the elastic deformation of the spring. When the shuttle-shaped scraper 4 jumps up and down, the spring is compressed and released synchronously. The spring hinge 8 is a commonly used component and will not be described in detail here.

[0042] Further, see Figure 3The bottom of the support plate 1 is provided with two support plates 201 and a rotating shaft 202 connecting the two support plates 201. The two support plates 201 are spaced apart along the first direction. The rotating shaft 202 passes through the rolling wheel 2 axially. The top of the support plate 201 is fixedly connected to the bottom of the support plate 1 to form an integral unit. Together with the rotating shaft 202, they form the rotating shaft of the rolling wheel 2. The guide wheel 3 also adopts the structure of two support plates 201, but the diameter of the guide wheel 3 is smaller than the diameter of the rolling wheel 2. The bottom surface of the guide wheel 3 needs to be kept on the same horizontal plane as the bottom surface of the rolling wheel 2. Therefore, the length of the support plate 201 used to support the guide wheel 3 is longer than the length of the support plate 201 used to support the rolling wheel 2.

[0043] Furthermore, to ensure steering flexibility and adapt to the curvature of the road axis to be leveled, as an optional embodiment, the guide wheel 3 is configured as a swivel wheel.
