Description

Technical Field

[0001] The invention relates to the field of road repair, and in particular to a rapid repair method for damaged concrete roads and floors. Background Art

[0002] Concrete roads and floors often suffer from varying degrees of damage, such as cracks, potholes, and peeling, during long-term use due to various natural and human factors, such as heavy-loaded vehicle rolling, chemical corrosion, freeze-thaw cycles, etc. These damages not only affect the aesthetics of roads and floors, but more importantly, they reduce their structural strength and safety, posing potential safety hazards to vehicles and pedestrians.

[0003] Existing methods for repairing damaged concrete roads and floors are often time-consuming and cannot effectively ensure that the repaired concrete is tightly bonded to the original road surface, which is prone to secondary cracking and falling off. One of the main reasons is that the damaged area is not thoroughly cleaned before repair, resulting in a loose connection between the repair material and the original road surface, which is prone to re-damage. In addition, the leveling and compaction operations are not thorough during the repair, resulting in a large number of gaps in the repair material, low structural strength, and affecting the quality of the repaired road surface. Summary of the invention

[0024] Beneficial effects of the present invention:

[0025] (1) The present invention uses an electric polisher and a high-pressure water gun to thoroughly clean the damaged parts, ensuring that the repair material can fit closely to the original road surface, reducing secondary cracking and falling off after repair, thereby improving the overall repair efficiency; using the vibration module and smoothing module in the scraping equipment to vibrate, compact and smooth the repair material, effectively eliminating the gaps inside the repair material, improving the structural strength of the repaired part, and making the repaired road surface smoother and more durable; the turntable in the scraping equipment is designed to be a multi-layer structure, and the outer diameter of the turntable in contact with the vibration column can be adjusted according to the hardness of the repair material and the actual situation of the repair part, thereby achieving different compaction degrees of the repair material and enhancing the adaptability and flexibility of the equipment; the repair method provided by the present invention is easy to operate and does not require complex technology and equipment support to achieve rapid repair of damaged concrete roads and floors.

[0026] (2) The present invention sets a power module, a smoothing module and a vibration module. The three cooperate to achieve short-time alternation of smoothing and vibration.

It is particularly suitable for the process of leveling the road surface in the later stage of repair. When the bottom surface of the repaired part has been fully compacted, by increasing the downward pressure amplitude on the protrusion and maintaining a lower downward pressure amplitude on the lower part, the overall flatness can be maintained and the accuracy of road repair can be improved.

[0042] The scraping equipment used in S3 includes:

[0043] A frame 1, wherein a power module 2 is disposed on the frame 1, wherein the power module 2 is used to provide a driving force, a walking wheel is disposed at the bottom of the frame 1, and a handrail is also disposed on one side of the frame 1;

[0044] A vibration module 3, which is also disposed on the frame 1 and connected to the power module 2, and is used for vibrating and compacting the repair material;

[0045] The smoothing module 4 is arranged on both sides of the frame 1 and connected to the power module 2 for smoothing the repair material.

[0046] The present invention uses an electric polisher and a high-pressure water gun to thoroughly clean the damaged parts, ensuring that the repair material can fit closely to the original road surface, reducing secondary cracking and falling off after repair, thereby improving the overall repair efficiency; using the vibration module 3 and the smoothing module 4 in the scraping equipment, the repair material is vibrated, compacted and smoothed, effectively eliminating the gaps inside the repair material, improving the structural strength of the repaired part, and making the repaired road surface smoother and more durable; the turntable 35 in the scraping equipment is designed to be a multi-layer structure, and the outer diameter of the turntable 35 in contact with the vibration column 31 can be adjusted according to the hardness of the repair material and the actual situation of the repair part, so as to achieve different compaction degrees of the repair material and enhance the adaptability and flexibility of the equipment; the repair method provided by the present invention is easy to operate and does not require complex technology and equipment support to achieve rapid repair of damaged concrete roads and floors.

[0047] The vibration module 3 includes a vibration column 31, which is configured as a T-shaped structure. The vibration column 31 is slidably installed in a movable sleeve 32, and the movable sleeve 32 is arranged on the frame 1. A compacting plate 33 is fixedly provided at the bottom end of the vibration column 31, and the compacting plate 33 is located below the frame 1. A buffer spring 34 is provided between the vibration column 31 and the top of the movable sleeve 32. A turntable 35 is provided above the vibration column 31, and the turntable 35 is configured as a cam structure. The middle part of the turntable 35 is rotatably installed on the frame 1 through a rotating shaft 36, and the turntable 35 is driven by the power module 2.

[0048] The smoothing module 4 includes a frame plate 41, a hollow groove 42 is provided in the middle of the frame plate 41, and the compacting plate 33 moves up and down in the hollow groove 42. Two movable grooves 43 are symmetrically provided on the frame plate 41, and a connecting portion 44 is slidably connected in the movable groove 43. A scraper 45 is fixedly provided at the bottom end of the connecting portion 44. As an embodiment, bolts are provided on the side of the frame plate 41, and the scraper 45 can be fixed by supporting the connecting portion 44 with the bolts; the frame plate 41 is driven by the power module 2 to move up and down; both sides of the scraper 45 are arranged as inclined surfaces 7, and the two inclined surfaces 7 are arranged in parallel, and the bottom end of the scraper 45 close to the compacting plate 33 is an acute angle 8. By setting the scraper 45 to be parallel to the cross section, when the frame 1 is pushed forward, the scraper 45 that first contacts the repair material is always on the obtuse side, and the space formed between the scraper 45 and the road surface is used to first compact and fill the excess repair material downward. The scraper 45 is designed to be parallel to the cross section, which can more effectively compact and evenly distribute the repair material on the road surface, reducing the situation where the excess material is passively pushed away, and improving the smearing efficiency and quality; the space formed between the scraper 45 and the road surface can first compact and fill the excess repair material downward, so that the combination between the repair material and the road surface is tighter, which helps to reduce the occurrence of hollowing and crack defects and improve the repair quality; the design structure of the entire smearing module 4 is simple and easy to operate, which can greatly improve the construction efficiency and quality;

[0049] The power module 2 includes a driving motor 21, an automatic telescopic rod 22 and a controller. The driving motor 21 is installed on the frame 1, and the driving motor 21 is transmission-connected to the turntable 35. A plurality of automatic telescopic rods 22 are provided. The telescopic end of the automatic telescopic rod 22 is fixedly connected to the top surface of the frame plate 41, and the bottom end of the automatic telescopic rod 22 is fixedly connected to the frame 1.

[0050] In order to solve the problems in the background technology, the present invention is provided with a power module 2, a smoothing module 4 and a vibration module 3. The three cooperate to realize the short-time alternation of smoothing and vibration. Compared with the actions of smoothing and vibrating separately, on the one hand, vibrating and compacting immediately after smoothing can effectively save the interval time to improve the overall repair efficiency; on the other hand, compacting immediately after smoothing can improve the compaction effect, thereby improving the tightness of the connection between the repair material and the road surface, and at the same time, the repair material can be effectively used to perform the maximum compaction effect, promote the replacement of the repair quality, and avoid the situation that when compacting separately after smoothing, it is found that the repaired part is uneven, resulting in multiple supplements of repair materials, and the repair material with too long an interval time will be solidified to a certain extent, and there will be certain bonding problems between the new repair material, which will bury hidden dangers for the subsequent repair of the road surface;

[0051] Specifically, the staff grasps the handrail and pushes the frame 1 to move. When the repaired road surface is reached, if it is determined that it needs to be smoothed, the automatic telescopic rod 22 drives the frame plate 41 to move down to the bottom until the bottom surface of the scraper 45 can contact the road surface. At this time, the scraper 45 located in front of the compacting plate 33 always keeps in contact with the road surface under the action of gravity. When encountering a raised repaired road surface, it will be forcibly pushed to smooth it. Then the compacting plate 33 reaches the repair position of preliminary smoothing. Driven by the drive motor 21, the turntable 35 is moved. It rotates periodically, thereby pushing the vibration column 31 below to move downward intermittently, and the buffer spring 34 is used to drive the vibration column 31 to reset, so that the vibration column 31 maintains high-frequency up and down reciprocating vibration, thereby realizing vibration compaction of the smoothing and repairing position, and then the scraper 45 on the rear side smoothes again, and the above process is repeated to realize the repeated action of smoothing → vibration compaction → smoothing, so that the excess repair material in the smoothing process can be timely filled into the depressed position after compaction, so that a batch of repair materials can achieve the dual purposes of smoothing and compaction, which is convenient and quick.

[0052] A lever 46 is provided at the top of one of the connecting parts 44, the middle part of the lever 46 is hinged on the frame 1, the bottom end of the lever 46 is movably connected to the top of the connecting part 44 through a connecting piece 47, a ball 48 is embedded and connected to the top of the lever 46, and the ball 48 can roll freely, and the top end of the lever 46 contacts the side end of the turntable 35;

[0053] At least one limiting portion 9 is disposed on the rotating shaft 36, and a limiting groove 10 corresponding to the limiting portion 9 is disposed at the contact point between the rotating disk 35 and the rotating shaft 36;

[0054] When the end of the lever 46 presses the rotating disk 35 , the rotating disk 35 can be pushed to slide on the rotating shaft 36 . A limiting sleeve 5 is provided on the rotating shaft 36 . A return spring 6 is sleeved at the position of the rotating shaft 36 between the limiting sleeve 5 and the rotating disk 35 .

[0055] As one embodiment, the outer ring of the turntable 35 is configured as a boss structure, and the outer diameter of the turntable 35 gradually increases along the axis direction.

[0056] As one embodiment, the turntable 35 is arranged in a multi-layer structure, and the outer diameter of each layer of the turntable 35 is gradually increased along the axis direction. The turntable 35 is pushed to move by a lever 46 to change the outer diameter of the turntable 35 in contact with the vibration column 31.

[0057] In the present invention, in order to adapt to the compaction requirements of different protrusion heights of the repair material, a lever 46 is provided, the middle part of the lever 46 is hinged on the frame 1, the bottom end of the lever 46 is movably connected to the top end of the connecting portion 44 through a connecting piece 47, and the top end of the lever 46 is embedded with a ball 48. When the repaired road surface is raised, it will fall into the angle between the scraper 45 and the bottom surface, so that the scraper 45 is passively lifted, driving the connecting piece 47 to push the lever 46, so that the end of the lever 46 pushes the turntable 35 to move along the rotating shaft 36, thereby adaptively adjusting the outer diameter of the turntable 35 according to the height of the repaired road surface, so that the vibration The downward pressure of the column 31 becomes larger, thereby achieving a more efficient compaction and leveling effect. This is especially suitable for the process of leveling the road surface in the later stage of repair. At this time, the bottom surface of the repair is fully compacted, and the top surface needs to be kept flat. Therefore, the downward pressure amplitude is increased for the raised part and reduced for the lower raised part to maintain the overall flatness and improve the accuracy of the entire road repair; when the road surface remains at the same height, the scraper 45 that has lost its lifting force falls back on the bottom surface. At this time, the reset spring 6 will push the turntable 35 to reset and return to the initial downward pressure amplitude, so the compaction plate 33 continues to compact until the road surface is compacted and leveled.

[0058] In summary, by setting the lever 46, the ball 48 and the turntable 35, the downward pressure amplitude of the vibration column 31 can be adaptively adjusted according to the height of different protrusions on the repaired road surface. When encountering a protrusion, the scraper 45 is passively lifted, and the turntable 35 is pushed to move along the shaft 36 by the action of the lever 46, thereby changing the outer diameter of the turntable 35, so that the downward pressure amplitude of the vibration column 31 increases, and the protruding part is effectively compacted. It is particularly suitable for the process of leveling the road surface in the later stage of repair. When the bottom surface of the repaired part has been fully compacted, by increasing the downward pressure amplitude on the protrusion and maintaining a lower downward pressure amplitude on the lower part, the overall flatness can be maintained and the accuracy of road repair can be improved.

[0059] Since the compaction amplitude can be adjusted adaptively, road bumps of different heights can be compacted more effectively, thereby reducing the number of repeated compactions and manual adjustments and improving the compaction efficiency. By setting the reset spring 6 and the limit sleeve 5, when the road surface remains at the same height, the scraper 45 that loses the lifting force will fall back on the bottom surface, and the reset spring 6 pushes the turntable 35 to reset to the initial state. This reset mechanism ensures the stability of the compaction plate 33 during the compaction process and avoids uneven road surfaces caused by excessive or insufficient compaction. The lever 46, connecting piece 47, ball 48 and turntable 35 in this solution are compactly designed and easy to install and debug. At the same time, due to the use of an adaptive adjustment mechanism, the need for manual operation is reduced, making the entire compaction process simpler and more efficient.

[0060] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
