Description

Technical Field

[0001] This invention relates to the field of road surface leveling technology, specifically to a road surface leveling device and method for asphalt pavement laying. Background Technology

[0002] Asphalt pavement is one of the most widely used high-grade pavements in road construction. When laying asphalt pavement, asphalt is laid on the road surface by a paving machine, and then flattened by the flattening rollers on a flattening machine to make the asphalt pavement smooth.

[0003] When a leveling machine levels a newly laid asphalt pavement, it typically uses a leveling roller to flatten the pavement. Asphalt roads usually have many clods of earth and stones on both sides. After the asphalt is laid, stones may appear on the surface due to various reasons. Because the newly laid asphalt is still relatively soft, the leveling roller will press these stones into the pavement during the leveling process, thus damaging the pavement's integrity. Over time, these stones may break, leaving a large pit and affecting the pavement's usability. Summary of the Invention

A guardrail is fixedly connected to the bottom of the main body away from the rotating frame.

[0009] Preferably, the moving mechanism also includes a positioning rod, which is fixedly connected to the end of the winding spring away from the winding rod. The positioning rod is rotatably connected to the bottom of the main body, and the winding rod rotates through the main body. The outer wall of the rotating frame abuts against the inner wall of the guardrail.

[0010] Preferably, a cleaning mechanism is provided on the top of the main body. The cleaning mechanism includes a connecting gear, which is rotatably connected to one end of the top of the main body near the main gear. The top of the connecting gear is a pulley. The tops of the two connecting frames are rotatably connected to auxiliary pulleys. The two auxiliary pulleys and the pulleys on the top of the connecting gear are fitted with belts. The auxiliary pulleys rotate through the connecting frames. The outer walls of the two auxiliary pulleys are fitted with cleaning frames at the ends away from the belts. The outer walls of the cleaning frames abut against the outer walls of the leveling wheels.

[0011] Preferably, a fixing mechanism is provided at the bottom of the main body. The fixing mechanism includes two mounting threaded brackets, which are inserted into the bottom of the main body. Each mounting threaded bracket has a washer fitted on its outer wall and a nut threaded onto its outer wall. Each mounting threaded bracket has a telescopic rod fixedly connected to its bottom. The output end of each telescopic rod is fitted with an elastic sleeve, and a triangular extension bracket is fixedly connected to its bottom.

[0012] Preferably, the scraping mechanism further includes two tension springs, both of which are fixedly connected inside the shrinkage groove and distributed on both sides of the telescopic plate. The elastic scraper is elastic, and the inner wall of the elastic scraper is fixedly connected with a bonding spring, which is made of a stretchable material.

[0013] Preferably, a cleaning mechanism is provided at the end of the triangular extension frame away from the telescopic rod. The cleaning mechanism includes a movable frame, which is rotatably connected to the side of the triangular extension frame away from the telescopic rod. Two sets of retraction holes are provided at the bottom of the movable frame, and buffer frames are slidably connected inside the two sets of retraction holes. Two buffer springs are fixedly connected to the top of the two buffer frames.

[0014] Preferably, the end of the buffer spring away from the buffer frame is fixedly connected to the inner wall of the contraction hole, and a cleaning triangle is fixedly connected to the bottom of the two buffer frames. The cleaning triangle is in a triangular posture, and a movable wheel is rotatably connected to the bottom of the cleaning triangle. Two auxiliary wheels are rotatably connected to the bottom of the cleaning triangle away from the movable wheel.

[0015] A method for leveling road surfaces using road leveling equipment for asphalt pavement paving includes the following steps:

[0016] S1: When the pushing device is connected to the external frame and pushes the main body to move, the forward pushing force will cause the sweeping tripod to press down, so that the sweeping tripod is close to the ground. Following the movement of the main body, the sweeping tripod moves on the ground through the auxiliary wheels and the moving wheels. The sweeping tripod pushes the debris to both sides of the sweeping tripod, thereby moving the debris on the road in front to both sides of the device.

[0017] S2: The main body drives the leveling wheel to roll at the bottom of the main body to flatten the asphalt pavement;

[0018] S3: The motor drives the half gear to rotate, and the half gear drives the half gear rotating shaft to rotate, which in turn drives the winding rod to rotate. This, in turn, drives the contact spring and the elastic scraper to move on the outer wall of the cleaning tripod through the rotating frame, scraping off the asphalt or debris stuck to the outer wall of the buffer spring.

[0019] S4: By meshing with the connecting gear, the belt can be driven to roll on the connecting gear, thereby driving the two auxiliary pulleys on the connecting frame to rotate, and driving the cleaning frame to roll. By contacting the outer wall of the cleaning frame with the outer wall of the leveling wheel, the surface of the leveling wheel can be cleaned.

[0020] Compared with the prior art, the present invention provides a road leveling device and a leveling method for asphalt pavement laying, which has the following beneficial effects:

[0021] 1. When the main body of this invention is moved by the external pushing device connected to the external frame, the forward pushing force will cause the sweeping tripod to press downward, making the sweeping tripod close to the ground. Thus, following the movement of the main body, the sweeping tripod moves on the ground through the auxiliary wheels and moving wheels, pushing the debris on the asphalt road surface forward. Through the triangular shape of the sweeping tripod, when the sweeping tripod comes into contact with the debris on the road surface, it will push the debris to both sides of the sweeping tripod, thereby moving the debris on the road surface to both sides of the device. When the main body drives the leveling wheel to perform the flattening work, it avoids pressing the stones on the asphalt road surface into the interior of the asphalt road surface, avoiding damage to the integrity of the asphalt road surface, and preventing the stones stuck in the asphalt road surface from breaking and leaving a large pit in the asphalt road surface over time, thus avoiding affecting the use of the asphalt road surface.

[0022] 2. When the sweeping tripod is close to the ground, the sweeping tripod causes the top buffer frame to slide inside the contraction hole, compressing the buffer spring. Simultaneously, in conjunction with the telescopic rod and elastic sleeve, the continuous force from the sweeping tripod is transmitted to the telescopic rod through the extension frame, causing the telescopic rod to contract and compressing the elastic sleeve for cushioning. This prevents excessive downward pressure from causing the extension frame to break. Furthermore, when encountering sloping surfaces, the rotating connection between the movable frame and the extension frame ensures that the sweeping tripod and moving wheels are close to the road surface, preventing gaps between the sweeping tripod and the ground that would prevent smaller stones from being cleared to the sides of the main body, thus improving the practicality of the device.

[0023] 3. This invention uses a motor to drive a half-gear to rotate, which in turn drives a half-gear rotating shaft to rotate, thereby rotating a take-up rod. This, in turn, causes the rotating frame to move the contact spring and elastic scraper against the outer wall of the cleaning tripod, scraping away asphalt or debris adhering to the outer wall of the buffer spring. As the elastic scraper moves with the shape of the cleaning tripod, it causes the telescopic plate and tension spring to stretch and contract inside the contraction groove. This allows the tension of the tension spring to keep the contact spring and elastic scraper tightly attached to the surface of the cleaning tripod, scraping away debris from the outer wall of the cleaning tripod. This avoids the problem of the cleaning tripod's outer wall being covered with debris, making it difficult to push the debris to the sides.

[0024] 4. During the rotation of the winding rod, this invention can move the elastic scraper and the contact spring from one end of the cleaning tripod to the other, while simultaneously tightening the winding rod. When the elastic scraper and the contact spring move to the other end, the half gear disengages from the half gear rotating shaft. Through the elastic force of the tightened winding spring, the winding rod rotates in the opposite direction, thereby causing the elastic scraper and the contact spring to reset via the rotating frame. This process repeats continuously. When the full gear continues to rotate, it can drive the full gear below the half gear to rotate. Through meshing with the connecting gear, it can drive the belt to roll on the connecting gear, thereby driving the two auxiliary pulleys on the connecting frame to rotate, and driving the cleaning frame to roll. By contacting the outer wall of the cleaning frame with the outer wall of the leveling wheel, the surface of the leveling wheel can be cleaned, improving the practicality of the device.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: As Figures 1-10 As shown, it includes a main body 1 and a protective shell 101, with the protective shell 101 fixedly connected to the top of the main body 1, and also includes:

[0038] A fixing mechanism 4 is provided at the bottom of the main body 1. The fixing mechanism 4 includes two mounting threaded brackets 401, which are inserted into the bottom of the main body 1. Each mounting threaded bracket 401 has a washer fitted onto its outer wall, and a nut is threaded onto its outer wall. A telescopic rod 402 is fixedly connected to the bottom of each mounting threaded bracket 401. An elastic sleeve 403 is fitted onto the output end of each telescopic rod 402. A triangular extension bracket 604 is fixedly connected to the bottom of each telescopic rod 402. When the cleaning tripod 605 is close to the ground, it will cause the top buffer bracket 603 to move within the contraction hole 602. The part slides and compresses the buffer spring 604. At the same time, it cooperates with the telescopic rod 402 and the elastic sleeve 403. The continuous force of the sweeping tripod 605 is transmitted to the telescopic rod 402 through the triangular extension frame 404, causing the telescopic rod 402 to retract and compress the elastic sleeve 403 for buffering. When encountering a sloping road surface, the movable frame 601 can be rotated and connected to the triangular extension frame 404 to make the sweeping tripod 605 and the moving wheel 606 close to the road surface, thereby avoiding the gap between the sweeping tripod 605 and the ground, which would prevent smaller stones from being unable to be cleaned to both sides of the main body 1.

[0039] A cleaning mechanism 6 is provided at the end of the triangular extension frame 404 away from the telescopic rod 402. The cleaning mechanism 6 includes a movable frame 601, which is rotatably connected to the side of the triangular extension frame 404 away from the telescopic rod 402. The bottom of the movable frame 601 has two sets of retraction holes 602, and a buffer frame 603 is slidably connected inside each of the two sets of retraction holes 602. Two buffer springs 604 are fixedly connected to the top of each of the two buffer frames 603. The end of the buffer spring 604 away from the buffer frame 603 is fixedly connected to the inner wall of the retraction hole 602. A cleaning triangle 605 is fixedly connected to the bottom of the two buffer frames 603. The cleaning triangle 605 is in a triangular posture. The bottom of the sweeping tripod 605 is rotatably connected to a movable wheel 606. Two auxiliary wheels 607 are rotatably connected to the bottom of the sweeping tripod 605 away from the movable wheel 606. The forward pushing force causes the sweeping tripod 605 to press down, so that the sweeping tripod 605 is in close contact with the ground. Thus, following the movement of the main body 1, the sweeping tripod 605 moves on the ground through the auxiliary wheels 607 and the movable wheel 606, and pushes the debris on the asphalt road in front forward. Through the triangular shape of the sweeping tripod 605, when the sweeping tripod 605 comes into contact with the debris on the road, it pushes the debris to both sides of the sweeping tripod 605, thereby moving the debris on the road in front to both sides of the device.

[0040] Two connecting frames 102 are fixedly connected to the left side of the main body 1. The two connecting frames 102 are symmetrically distributed back and forth with the main body 1 as the center. A movable cavity frame 103 is fixedly connected to the top of the main body 1. An external frame 104 is rotatably connected inside the movable cavity frame 103. A pushing device is connected to the external frame 104. When the main body 1 is moved by the external pushing device connected to the external frame 104, the forward pushing force will cause the cleaning triangle 605 to press down. A rotating frame 105 is fixedly connected to the bottom of the main body 1. A leveling wheel 106 is rotatably connected inside the rotating frame 105. The leveling wheel 106 compacts and flattens the asphalt pavement. A guardrail 107 is fixedly connected to the bottom of the main body 1 away from the rotating frame 105. The guardrail 107 can provide further protection for the structure below the main body 1.

[0041] Working principle: When the main body 1 is moved by the external pushing device connected to the external frame 104, the forward pushing force will cause the sweeping tripod 605 to press downward, making the sweeping tripod 605 close to the ground. Following the movement of the main body 1, the sweeping tripod 605 moves on the ground via the auxiliary wheel 607 and the moving wheel 606, pushing debris on the asphalt road surface forward. Through the triangular shape of the sweeping tripod 605, when it comes into contact with debris on the road surface, it pushes the debris to both sides of the sweeping tripod 605, thus moving the debris on the road surface to both sides of the device. When the main body 1 drives the leveling wheel 106 to perform flattening work, it avoids pressing stones into the asphalt road surface. When the sweeping tripod 605 is close to the ground, it causes the top buffer frame 603 to slide inside the retraction hole 602, compressing the buffer spring 604. Simultaneously, in conjunction with the telescopic rod 402 and the elastic sleeve 403, the continuous force from the sweeping tripod 605 is transmitted to the telescopic rod 402 through the extension frame 404, causing the telescopic rod 402 to retract and compressing the elastic sleeve 403 for cushioning. Furthermore, when encountering sloping surfaces, the rotating connection between the movable frame 601 and the extension frame 404 ensures that the sweeping tripod 605 and the moving wheels 606 are close to the ground, thus preventing gaps between the sweeping tripod 605 and the ground from preventing smaller stones from being cleared to the sides of the main body 1.

[0042] Example 2: As Figures 1-10As shown, it also includes an active mechanism 2, which is located at the bottom of the main body 1. The active mechanism 2 includes a motor 201, which is fixedly connected to the top of the protective shell 101. A half gear 202 is fixedly connected to the output end of the motor 201, and a full gear 203 is fixedly connected to the bottom of the half gear 202. The full gear 203 is rotatably connected to the top of the main body 1. A half gear rotating shaft 204 is rotatably connected to the top of the main body 1 near the half gear 202. A winding rod 205 is fixedly connected to the bottom of the half gear rotating shaft 204. A winding spring 206 is fixedly connected to the outer wall of the winding rod 205. A rotating frame 208 is fixedly connected to the bottom of the winding rod 205. A winding spring is provided on the side of the rotating frame 208 away from the winding rod 205. The groove 209 and the movable mechanism 2 also include a positioning rod 207, which is fixedly connected to the end of the winding spring 206 away from the winding rod 205. The positioning rod 207 is rotatably connected to the bottom of the main body 1. The winding rod 205 rotates through the main body 1. The outer wall of the rotating frame 208 abuts against the inner wall of the guardrail 107. The motor 201 drives the half gear 202 to rotate, and the half gear 202 drives the half gear rotating shaft 204 to rotate, thereby driving the winding rod 205 to rotate. Thus, the rotating frame 208 drives the contact spring 505 and the elastic scraper 504 to move on the outer wall of the cleaning tripod 605, scraping off the asphalt or debris stuck to the outer wall of the buffer spring 604.

[0043] The scraping mechanism 5 is disposed inside the shrinkage groove 209. The scraping mechanism 5 includes a telescopic plate 501, which is slidably connected inside the shrinkage groove 209. A limit frame 503 is fixedly connected to the side of the telescopic plate 501 away from the shrinkage groove 209. An elastic scraper 504 is fixedly connected to the side of the limit frame 503 away from the telescopic plate 501. The scraping mechanism 5 also includes two tension springs 502, both of which are fixedly connected inside the shrinkage groove 209 and distributed on the telescopic plate 501. On both sides, the elastic scraper 504 is elastic, and the inner wall of the elastic scraper 504 is fixedly connected to the bonding spring 505, which is made of a ductile material. When the elastic scraper 504 moves with the shape of the cleaning tripod 605, it will drive the telescopic plate 501 and the tension spring 502 to stretch and contract inside the contraction groove 209. Thus, the tension of the tension spring 502 can make the bonding spring 505 and the elastic scraper 504 stick tightly to the surface of the cleaning tripod 605 to scrape away the debris on the outer wall of the cleaning tripod 605.

[0044] A cleaning mechanism 3 is provided on the top of the main body 1. The cleaning mechanism 3 includes a connecting gear 301, which is rotatably connected to one end of the top of the main body 1 near the full gear 203. The top of the connecting gear 301 is a pulley. The tops of the two connecting frames 102 are rotatably connected to auxiliary pulleys 302. Belts 303 are fitted inside the pulleys on the tops of the two auxiliary pulleys 302 and the connecting gear 301. The auxiliary pulleys 302 rotatably pass through the connecting frame 102. A cleaning mechanism is fitted on the outer wall of the two auxiliary pulleys 302 away from the belt 303. The cleaning rack 304 has its outer wall abutting against the outer wall of the leveling wheel 106. When the full gear 203 rotates continuously, it can drive the full gear 203 below the half gear 202 to rotate. Through meshing with the connecting gear 301, it can drive the belt 303 to roll on the connecting gear 301, thereby driving the two auxiliary pulleys 302 on the connecting rack 102 to rotate, driving the cleaning rack 304 to roll. Through the contact between the outer wall of the cleaning rack 304 and the outer wall of the leveling wheel 106, the surface of the leveling wheel 106 can be cleaned.

[0045] Working principle: The motor 201 drives the half gear 202 to rotate, which in turn drives the half gear rotating shaft 204 to rotate, thereby driving the take-up rod 205 to rotate. This, in turn, drives the rotating frame 208 to move the contact spring 505 and the elastic scraper 504 on the outer wall of the cleaning tripod 605, scraping away the asphalt or debris adhering to the outer wall of the buffer spring 604. When the elastic scraper 504 moves with the shape of the cleaning tripod 605, it drives the telescopic plate 501 and the tension spring 502 to stretch and contract inside the contraction groove 209. Thus, the tension of the tension spring 502 makes the contact spring 505 and the elastic scraper 504 stick tightly to the surface of the cleaning tripod 605, scraping away the debris on the outer wall of the cleaning tripod 605. During the rotation of the take-up rod 205, it can drive the elastic scraper 504 and the contact spring 505 to move from the cleaning tripod. When one end of 605 moves to the other end, the take-up rod 205 is tightened. When the elastic scraper 504 and the contact spring 505 move to the other end, the half gear 202 disengages from the half gear rotating shaft 204. The elastic force of the tightened take-up spring 206 drives the take-up rod 205 to rotate in the opposite direction, thereby driving the elastic scraper 504 and the contact spring 505 to reset through the rotating frame 208. This process repeats. When the full gear 203 continues to rotate, it can drive the full gear 203 below the half gear 202 to rotate. Through meshing with the connecting gear 301, it can drive the belt 303 to roll on the connecting gear 301, thereby driving the two auxiliary pulleys 302 on the connecting frame 102 to rotate, driving the cleaning frame 304 to roll. Through the contact between the outer wall of the cleaning frame 304 and the outer wall of the leveling wheel 106, the surface of the leveling wheel 106 can be cleaned.

[0046] A method for leveling road surfaces using road leveling equipment for asphalt pavement paving includes the following steps:

[0047] S1: When the pushing device is connected to the external frame 104 and pushes the main body 1 to move, the forward pushing force will cause the sweeping tripod 605 to press down, so that the sweeping tripod 605 is close to the ground. Following the movement of the main body 1, the sweeping tripod 605 moves on the ground through the auxiliary wheel 607 and the moving wheel 606. The sweeping tripod 605 pushes the debris to both sides of the sweeping tripod 605, thereby moving the debris on the road in front to both sides of the device.

[0048] S2: The main body 1 drives the leveling wheel 106 to roll at the bottom of the main body 1 to flatten the asphalt pavement;

[0049] S3: The motor 201 drives the half gear 202 to rotate, and the half gear 202 drives the half gear rotating shaft 204 to rotate, thereby driving the winding rod 205 to rotate. This, in turn, drives the rotating frame 208 to move the contact spring 505 and the elastic scraper 504 on the outer wall of the cleaning tripod 605, scraping off the asphalt or debris stuck to the outer wall of the buffer spring 604.

[0050] S4: By meshing with the connecting gear 301, the belt 303 can be driven to roll on the connecting gear 301, thereby driving the two auxiliary pulleys 302 on the connecting frame 102 to rotate, driving the cleaning frame 304 to roll. By contacting the outer wall of the cleaning frame 304 with the outer wall of the leveling wheel 106, the surface of the leveling wheel 106 can be cleaned.
