A road repair device with adaptive road surface

Abstract

The present invention relates to the field of highway repair, and more particularly to an adaptive road surface highway repair device, comprising a cart, a storage tank, a mounting block, and a mounting rod, wherein the cart is mounted with the storage tank, the cart is connected to the mounting block, and the mounting block is slidably connected to the L-shaped mounting rod. The present invention achieves good adaptability to uneven roads and sloping roads through the front and rear scrapers, thereby avoiding the problem in the prior art where the flat mold bottom surface cannot adapt to the uneven road surface on both sides, resulting in the inability to completely scrape off the asphalt on the road surface. After the crack is repaired, filler on both sides of the crack is higher than the original road surface, resulting in an uneven road surface and wasted filler.

Description

Technical Field

[0001] The present invention relates to the field of highway repair, and in particular to a highway repair device with adaptive road surface. Background Art

[0002] When small cracks appear on an asphalt road surface, they are repaired by filling the cracks with asphalt filler. Conventional methods for repairing road cracks involve placing a square mold over the crack, with the bottom of the mold in contact with the road surface on both sides of the crack. Heated asphalt filler is then loaded into the mold and driven along the crack. As the mold moves along the crack, the filler falls into the crack while scraping and pushing the filler from the road surface on both sides of the crack forward, preventing the filler from becoming covered with a layer of filler. This causes the road surface on both sides of the crack to rise above the original surface, creating a significant height difference that can affect driving stability when vehicles are traveling over it. Cracks are primarily caused by uneven ground or tilted roads. Conventional square molds have a flat bottom surface and are unable to adapt to uneven or tilted roads on either side of the crack. This causes one side of the mold to become suspended, out of contact with the road surface. Especially when the road surface on both sides of the crack is tilted, the bottom of the mold remains in contact with one side, leaving the other side hanging more noticeably. The filler in the mold then flows over from the suspended position below and covers the road surface, causing the road surface to rise above the original surface, creating a significant height difference.

[0003] In addition, since the mold is suspended in the air, the filler overflows from the gap, which not only fails to fill the cracks accurately, but also causes unnecessary waste of asphalt filler, increasing the repair cost and material loss. Summary of the Invention

[0004] In order to overcome the shortcomings of existing square molds that cannot adapt to uneven or inclined road surfaces on both sides of the crack, cannot scrape off the fillers on the road surfaces on both sides of the crack, and are covered with a layer of asphalt filler, resulting in the road surfaces on both sides of the crack being higher than the original road surface, with a significant height difference, which easily affects the driving stability of vehicles driving on it, the present invention provides a road repair device with adaptive road surface.

At the same time, the operator does not need to turn the direction of the cart to fill the missing parts, reducing workload and improving the efficiency of highway repair work.

[0031] like Figures 1-9As shown, an adaptive road surface repair device includes a cart 1 and a storage tank 2; a discharge port 101 is opened on one side of the cart 1; a handrail 102 is welded to the cart 1; the storage tank 2 is mounted on the cart 1; a gas filter is provided in the storage tank 2; a screw pump is provided in the storage tank 2; a discharge pipe 201 is provided on the lower side of the storage tank 2 toward the discharge port 101; the outlet of the discharge pipe 201 is located above the discharge port 101;

[0032] It also includes a mounting block 3, a mounting rod 4, a first elastic member 5, a front scraper 6, a rear scraper 7 and a clamping assembly; the trolley 1 is connected to the mounting block 3; the mounting block 3 is slidably connected to the L-shaped mounting rod 4; the mounting rod 4 is composed of a vertical rod 401 and a horizontal rod 402; a first elastic member 5 is connected between the horizontal rod 402 and the mounting block 3; the first elastic member 5 is a spring; the front scraper 6 is rotatably connected to the horizontal rod 402; a left baffle 601 is welded to the left side of the front scraper 6; the rear scraper 7 is rotatably connected to the horizontal rod 402; A right baffle 701 is welded to the right side of the scraper 7, and the front surface of the rear scraper 7 contacts the rear surface of the front scraper 6; the lower side of the front scraper 6 is set at an oblique angle, and when there is filler on the lower side of the front scraper 6, it is convenient for the front scraper 6 to be inserted into the filler and squeeze it back to the front of the front scraper 6; the rear scraper 7 is longer than the front scraper 6; the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 are combined to form a U-shaped accommodating space; the left baffle 601 and the right baffle 701 are both made of high-density metal; a clamping assembly is connected to the vertical rod 401.

[0033] The clamping assembly includes a guide rod 21, a connecting rod 22, a second elastic member 23, a front clamping rod 24 and a rear clamping rod 25; a pair of horizontally arranged guide rods 21 are welded to the vertical rod 401; the two guide rods 21 are slidably connected to the connecting rod 22; an L-shaped moving rod 2201 is welded to the connecting rod 22; each guide rod 21 is fixedly connected to a second elastic member 23; the second elastic member 23 is a spring; the two second elastic members 23 are fixedly connected to the connecting rod 22; two front clamping rods 24 are fixedly connected to the lower side of the connecting rod 22; each guide rod 21 is fixedly connected to a rear clamping rod 25; the rear scraper 7 and the front scraper 6 are located between the front clamping rod 24 and the rear clamping rod 25.

[0034] A rotating ring 31 is rotatably connected to the discharge port 101 of the trolley 1 ; the mounting block 3 is fixedly connected to the rotating ring 31 .

[0035] The lower side of the rear scraper 7 is set at an angle, and the angle direction of the rear scraper 7 is opposite to the angle direction of the front scraper 6, which is conducive to the rear scraper 7 and the front scraper 6 being inserted into the filler below and contacting the road surface.

[0036] The front lower sides of the left baffle 601 and the right baffle 701 are rounded, which helps the left baffle 601 and the right baffle 701 to adapt to slight bumps in the road surface when they move forward close to the road surface.

[0037] A rubber sleeve is provided on the vertical rod 401 to increase friction and ensure that the operator holds the vertical rod 401 firmly.

[0038] The surface of the moving rod 2201 is provided with rubber protrusions to increase the friction when the operator holds it.

[0039] The surfaces of the front clamping rod 24 and the rear clamping rod 25 are both provided with a rubber layer. The front side surface of the front scraper 6 is rough, and the rear side surface of the rear scraper 7 is rough, which is used to increase the friction with the rear scraper 7 and the front scraper 6.

[0040] Before using the present invention, the operator installs a battery on the cart 1 to power the screw pump in the storage tank 2, and adds heated asphalt filler into the storage tank 2. After the asphalt filler is stored in the storage tank 2, the storage tank 2 is sealed, and the harmful gas generated by the hot asphalt is filtered through the gas filter inside the storage tank 2 to prevent the operator from inhaling the harmful gas and affecting health and safety; then the operator pushes the cart 1 of the present invention to the starting point of the road crack by using the handrail 102, so that the discharge port 101 is aligned with the crack, and at the same time, the crack is aligned with the middle of the U-shaped space formed by the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701, and the opening of the U-shaped space faces the forward direction of the present invention; and the stroke length of the vertical rod 401 makes the lowest point of the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 lower than the lowest point of the cart 1 running wheel, and then after the present invention is placed on the road surface, the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 are lifted up by the road surface, The mounting rod 4 is driven to move upward, and the crossbar 402 compresses the first elastic member 5. At the same time, the rebound force of the first elastic member 5 squeezes the crossbar 402 in the opposite direction, so that the bottoms of the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 are close to the road surface. Then the operator controls the screw pump in the storage tank 2 to discharge the asphalt filler through the discharge pipe 201. The discharged asphalt filler will fall onto the road below through the discharge port 101, and the asphalt filler is located on the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle. The asphalt filler is pushed forward by the front scraper 6 and the rear scraper 7 so as to fill the cracks. When the asphalt filler is pushed forward by the front scraper 6, the asphalt filler is pushed forward to fill the cracks. When the road surface on both sides of the cracks is uneven ... Figure 6Described from the perspective shown, the left baffle 601 is located on the left side of the road crack, and the right baffle 701 is located on the right side of the road crack. When the ground on the left side of the crack is lower, the left baffle 601 made of a high-density metal material acts as a counterweight for the front scraper 6, and the front scraper 6 will tilt to the left with the cross bar 402 as the rotation fulcrum, so that the bottom of the front scraper 6 is in close contact with the inclined ground on the left; when the ground on the left side of the crack is lower, the right baffle 701 made of a high-density metal material acts as a counterweight for the rear scraper 7, and the rear scraper 7 will tilt to the right with the cross bar 402 as the rotation fulcrum, so that the bottom of the rear scraper 7 is in close contact with the inclined ground on the right; This ensures that the front scraper 6 and the rear scraper 7 adapt to the uneven road surface on both sides of the highway crack in the process of pushing the asphalt filler forward, ensuring that the asphalt on the highway surface is scraped flat. Compared with the existing flat mold bottom surface, which cannot adapt to the uneven and inclined road surface on both sides, it will lead to the inability to scrape the asphalt on the highway surface cleanly. As a result, after the crack is repaired, there are fillers on both sides of the crack that are higher than the original highway surface, resulting in an uneven highway surface and waste of fillers. The front scraper 6 and the rear scraper 7 of the present invention have good adaptability to uneven and inclined roads on both sides, so as to avoid the problems existing in the prior art.

[0041] In addition, when the front scraper 6 is in a left-tilted state, there will be a gap between the right bottom surface of the front scraper 6 and the road surface on the right side, and part of the filler will be filled in the gap. When the front scraper 6 moves from the inclined road surface to the straight road surface, the filler under the right bottom surface of the front scraper 6 will easily hinder the front scraper 6 from returning to a straight state. Therefore, the lower side of the front scraper 6 is set at an oblique angle. When the front scraper 6 moves from the inclined road surface to the straight road surface, the left bottom surface of the front scraper 6 is lifted up by the ground, causing the right side to rotate downward and return to a straight state as a whole. The oblique bottom of the front scraper 6 will be conducive to inserting into the filler under the right bottom surface and squeezing the filler to the front side of the front scraper 6, ensuring that the front scraper 6 can smoothly return from the inclined state to the straight state during use to adapt to changes in the road surface.

[0042] Compared with asphalt pavement, concrete pavement cannot be flattened by heavy machinery such as rollers after construction. Concrete pavement flattened by light machinery has poor flatness and may have some bumps and depressions. When the present invention is used to repair cracks in concrete pavement, the depressions can be filled with fillers, while the protrusions will hinder the front scraper 6 close to the ground during the forward movement of the present invention, making it impossible for the present invention to move forward. Therefore, when encountering a protrusion obstacle, the operator holds the vertical rod 401 and the moving rod 2201. At this time, the moving rod 2201 will be squeezed and moved toward the vertical rod 401, and the moving rod 2201 drives the connecting rod 22 along The guide rod 21 moves toward the vertical rod 401, and the connecting rod 22 compresses the second elastic member 23 during the movement, and at the same time drives the front clamping rod 24 to move to the front scraper 6. The front clamping rod 24 will squeeze the front surface of the front scraper 6, and at the same time the rear clamping rod 25 will contact the rear surface of the rear scraper 7, so that the front clamping rod 24 and the rear clamping rod 25 clamp and fix the front scraper 6 and the rear scraper 7, so that the front scraper 6 and the rear scraper 7 maintain the current inclination angle. Then the operator lifts the vertical rod 401 and the moving rod 2201 upward, and the vertical rod 401 will move upward relative to the mounting block 3, driving the cross bar 402, the guide rod 21 and the connecting parts to move upward. When the cross bar 402 moves upward, it compresses the first elastic member 23. The front scraper 6 and the rear scraper 7 are moved upwards by the cross bar 402, and the left baffle 601 and the right baffle 701 are moved upwards. At this time, the operator continues to push the cart 1. When the operator feels that the movement of the present invention is not hindered, it means that the bottom of the front scraper 6 and the rear scraper 7 are already higher than the raised obstacle. At this time, the current height of the front scraper 6 and the rear scraper 7 is maintained to avoid the gap between the bottom of the front scraper 6 and the rear scraper 7 and the road surface being too large, resulting in a large amount of filler leakage. At the same time, the front scraper 6 and the rear scraper 7 are clamped by the front clamping rod 24 and the rear clamping rod 25 to fix the inclination angle. The rubber layer on the surface of the front clamping rod 24 and the rear clamping rod 25 increases and is aligned with the front scraper The friction force of the contact between the plate 6 and the rear scraper 7 ensures that when moving upward to avoid, the front scraper 6 and the rear scraper 7 are not affected by the counterweight of the left baffle 601 and the right baffle 701, but rotate with the cross bar 402 as the fulcrum, thereby preventing the front scraper 6 and the rear scraper 7 from tilting and contacting the raised obstacle again, and the present invention cannot move forward; after crossing the obstacle, the operator releases the vertical rod 401 and the moving rod 2201, and under the action of gravity and in conjunction with the extension of the first elastic member 5, the vertical rod 401 will slide downward relative to the mounting block 3, so that the bottom of the front scraper 6 and the rear scraper 7 are in contact with the road surface again, and then the operator can push the present invention forward again to repair the cracks.

[0043] In addition, when the front scraper 6 and the rear scraper 7 pass over the obstacle upward, a small gap appears between the bottom and the road surface. When the lifted front scraper 6 and the rear scraper 7 move forward, part of the filler will fall from the gap, resulting in part of the filler on the road surface being higher than the road surface. After the overall crack repair work is completed, the operator can also recover and clean up some of the fallen fillers to ensure the flatness of the road surface after the crack repair; at the same time, the location of the fallen filler corresponds to the raised obstacle originally existing on the road surface, and the fallen filler serves as a mark. When the operator recovers and cleans the fallen filler, he can use crushing tools to remove the raised obstacles originally existing on the road surface to prevent the raised obstacles from affecting the flatness of the road surface and endangering driving safety.

[0044] It should be noted that when the front scraper 6 and the rear scraper 7 move downward and contact the road surface, since the lower sides of the front scraper 6 and the rear scraper 7 are set at an oblique angle, the front scraper 6 and the rear scraper 7 will be inserted into the filler and then contact the road surface, which avoids the bottom of the front scraper 6 and the rear scraper 7 being blocked by the filler when moving downward and unable to contact the ground, resulting in a layer of filler on the road surface during subsequent repairs, causing the two sides around the repaired crack to be higher than the original road surface.

[0045] In the process of filling cracks in asphalt roads, since the heated asphalt filler itself is in a solid-liquid mixed state with poor fluidity, when the filler falls into the cracks by itself, the material falling is not smooth, and some areas are missing and not filled in place. Therefore, the unloading port 101 of the cart 1 is rotatably connected to the rotating ring 31, and the mounting block 3 and its connecting parts are fixed to the rotating ring 31. When the filler is missing in the cracks that have been filled by the present invention, Figure 1 As a direction reference, looking from top to bottom, the operator holds the vertical rod 401 to drive the mounting block 3 to rotate, and the mounting block 3 drives the rotating ring 31 to rotate 180 degrees clockwise. During this process, the U-shaped space formed by the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 will rotate 180 degrees, and the filler is originally confined in the U-shaped space. Then, when the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 rotate, it can ensure that the filler does not scatter, so that the filler remains in the U-shaped space. Figure 10 As shown, the U-shaped space opening formed by the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 will face the direction of the crack that has been filled on the rear side. Then the operator pulls the cart 1 backward, and the front scraper 6 will push the asphalt filler back to fill the missing part, thereby ensuring that the cracks in the highway are filled completely and avoiding missing parts. At the same time, the operator does not need to turn the direction of the cart 1 to fill the missing parts, thereby reducing workload and improving the efficiency of highway repair work.

[0046] Example 2

[0047] On the basis of Example 1, Figure 1 、 Figure 3 and Figures 8-10 As shown, a compacting assembly is also included, which includes a third elastic member 41, a fixed rod 42 and a rubber roller 43; two third elastic members 41 are connected to the lower side of the rotating ring 31; the third elastic member 41 is a spring telescopic rod; the telescopic ends of all third elastic members 41 are commonly connected to the fixed rod 42; a rubber roller 43 is rotatably connected to the fixed rod 42; the rubber roller 43 is located behind the rear scraper 7, and the axial direction of the rubber roller 43 is parallel to the rear side of the rear scraper 7.

[0048] The third elastic member 41 is rotatably connected to the fixing rod 42 ; thus, the two third elastic members 41 can be extended and retracted asynchronously to change the tilt angle of the fixing rod 42 and the rubber roller 43 .

[0049] After the filler is filled in the cracks of the road, there will be empty bags in some areas, which will cause the filler to collapse later. Due to the poor fluidity of the filler, the collapse may not occur immediately after the cracks of the road are filled. Therefore, it is necessary to compact the filler in the cracks to eliminate the empty bags and refill the collapsed positions caused by the empty bags in time. After the filling work is completed, the compaction work is carried out again. At this time, collapse occurs and the filling work needs to be re-performed, which is inefficient. A rubber roller 43 is provided on the rear side of the rear scraper 7. During the use of the present invention, the telescopic stroke of the third elastic member 41 is longer than the distance between the bottom surface of the rotating ring 31 and the lowest point of the walking wheel of the cart 1. When the lowest point of the rubber roller 43 contacts the road surface , the third elastic member 41 is in a compressed state, the third elastic member 41 will apply pressure to the fixed rod 42 in the reverse direction, and the fixed rod 42 drives the rubber roller 43 to move, so that the rubber roller 43 keeps in contact with the road surface. At the same time, the rubber roller 43 is rotatably connected to the fixed rod 42, and will roll as the present invention moves and compact the filler. After the filler is compacted, the filler collapses due to the empty bag. The operator can control the rotating ring 31 to drive the front scraper 6, the rear scraper 7, the left baffle 601 and the right baffle 701 to rotate clockwise 180 degrees so that the U-shaped space opening faces the rear, and then the present invention moves backward to refill the collapsed area in time, thereby improving work efficiency and avoiding subsequent collapse and re-repair, which increases workload.

[0050] Furthermore, when the road surface on both sides of the crack is uneven, taking the left side of the road as an example where the road surface is high and the right side is low, the third elastic member 41 on the left side contracts and the third elastic member 41 on the right side extends, and both third elastic members 41 are rotatably connected to the fixed rod 42. The fixed rod 42 will tilt from left to right, and then the rubber roller 43 will also tilt from left to right, thereby adapting to the uneven road surface and ensuring the compaction effect.

[0051] In addition, when the front scraper 6 and the rear scraper 7 are in an inclined state and push the filler into the crack, the upper surface of the filler scraped flat by the front scraper 6 and the rear scraper 7 will appear in a pointed cone shape. At this time, the rubber roller 43 will move closely following the rear scraper 7 to flatten the top of the pointed cone-shaped filler in time to avoid subsequent hardening of the pointed cone-shaped filler, damage to the vehicle tires caused by the vehicle running over the pointed cone-shaped position, and the unevenness of the pointed cone may cause instability in the vehicle driving, and thus cause safety accidents.

[0052] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
