Description

Technical Field

[0001] This utility model relates to the field of road crack treatment technology, and more specifically, to a road crack pretreatment and cleaning device. Background Technology

[0002] Road cracks refer to the continuous damage to the road structure (mainly asphalt or cement concrete pavement) caused by factors such as traffic loads, natural environment (temperature, precipitation), material aging, or construction defects. They manifest as cracks or gaps on or inside the pavement surface and are one of the most common early road defects.

[0003] Once road cracks form, if they are not cleaned and treated promptly, various pollutants can easily remain inside, causing continuous erosion and damage to the road surface. Specifically, oil leaks such as engine oil and antifreeze from vehicles can penetrate into the asphalt pavement, dissolving the gum and resin components in the asphalt, damaging its bonding properties, and causing the asphalt to "age and become brittle." This leads to the continuous expansion of crack width, resulting in more serious road defects such as potholes and loosening. In winter, salts (such as sodium chloride and calcium chloride) spread for snow melting can seep into the cracks of cement concrete pavements with rainwater, causing "electrochemical corrosion" with the internal steel reinforcement. This leads to the steel reinforcement rusting and expanding, compressing the concrete structure, causing concrete spalling and exposed reinforcement, and significantly reducing the strength of the road structure.

[0004] Existing road crack cleaning devices mostly employ a single cleaning method: some devices only use brushes or scrapers for mechanical scraping, which is insufficient to remove oil and salt crystals adhering to the cracks, resulting in incomplete cleaning; while some devices have liquid spraying functions, the delivery of cleaning fluid and the mechanical cleaning action are independent of each other and require separate operation. This not only results in low work efficiency, but also prevents the cleaning fluid from being applied precisely to the cracked area immediately after scraping, causing residual contaminants to re-adhere, affecting the bonding strength between subsequent repair materials and the road surface, and shortening the service life of the repaired road. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a road crack pretreatment and cleaning device, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a road crack pretreatment and cleaning device, including an installation cylinder, on which a cleaning component is provided;

[0007] The cleaning assembly includes a cover plate disposed at one end of the mounting cylinder, a mixing chamber is formed between the mounting cylinder and the cover plate, and a mounting block is disposed at the bottom of the inner wall of the mixing chamber, with a lower extension rod disposed at the bottom end of the mounting block;

[0008] The bottom end of the lower extension rod is fitted with a limiting sleeve, the bottom end of the limiting sleeve is hinged to a hinge frame, and the bottom of the hinge frame is provided with a cleaning rod.

[0009] Optionally, in one possible implementation, a conveying cylinder is slidably connected to the mounting block. The surface of the conveying cylinder has a liquid delivery slot located inside the mixing chamber, and a draining slot is provided at the bottom of the conveying cylinder. A connecting sleeve is provided at the top of the conveying cylinder. A rotating shaft is provided inside the mounting cylinder. A mixing block is fixedly provided at one end of the rotating shaft. An eccentric rod is rotatably connected to the mixing block. One end of the eccentric rod extends to the outside of the connecting sleeve and is rotatably connected to the connecting sleeve. The connecting sleeve is fixed to the conveying cylinder. A diversion groove is provided on the outside of the mixing block. A motor for driving the rotating shaft to rotate is provided at one end of the mounting cylinder. A sealing block is provided at the top of the mixing chamber, and a through hole is provided through the sealing block.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By combining mechanical scraping and cleaning fluid rinsing, deep cleaning of pollutants in road cracks can be achieved. The cleaning pole adopts a flat and sharp structure, and with the adaptive angle adjustment function of the articulated frame, it can closely fit the inner wall of cracks of different widths and efficiently scrape away solid impurities such as stones and solidified oil stains in the cracks.

[0012] The conveyor cylinder moves up and down, and the cleaning liquid in the mixing chamber is precisely sprayed into the crack area after scraping through the drainage tank. The cleaning liquid can quickly dissolve the residual oil, salt and other corrosive substances, and is carried out with the impurities by the cleaning rod, effectively blocking the continuous erosion of the road surface by pollutants and laying a good foundation for subsequent repair work.

[0013] The integrated transmission structure driven by the motor enables the synchronous linkage of cleaning action and liquid delivery: when the motor drives the rotating shaft to rotate, the mixing block stirs the cleaning liquid through the diversion tank and drives the conveying cylinder to reciprocate through the eccentric rod. The scraping, spraying and secondary cleaning processes can be completed simultaneously without the need for an additional power source to control the liquid delivery, thereby improving cleaning efficiency and quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This embodiment discloses a road crack pretreatment and cleaning device, which aims to solve the problem that existing road crack cleaning devices cannot simultaneously achieve efficient cleaning of impurities in cracks and precise delivery of cleaning fluid, resulting in incomplete cleaning and affecting the subsequent repair effect.

[0022] like Figure 1 As shown, the road crack pretreatment and cleaning device includes an installation cylinder 1, which is a cylindrical hollow structure made of high-strength aluminum alloy. This design ensures structural stability while reducing the overall weight of the device, making it easy for operators to handle or install it on traction equipment. The installation cylinder 1 integrates a cleaning component, which is the core structure for achieving crack cleaning and liquid delivery.

[0023] like Figure 3As shown, the cleaning assembly includes a cover plate 2 fixedly mounted at one end of the mounting cylinder 1. The cover plate 2 is detachably connected to the end face of the mounting cylinder 1 by bolts, facilitating subsequent maintenance and replacement of internal parts. A mixing chamber is formed between the mounting cylinder 1 and the cover plate 2. The mixing chamber is an annular cavity structure used to temporarily store cleaning fluids to be transported, such as degreasers and neutral detergents. A mounting block 3 is welded and fixed to the bottom of the inner wall of the mixing chamber. A lower extension rod 4 extends vertically downward from the bottom end of the block. The lower extension rod 4 is a cylindrical rod.

[0024] A limiting sleeve 5 is movably fitted at the bottom end of the lower extension rod 4. The inner wall of the limiting sleeve 5 is clearance-fitted with the outer wall of the lower extension rod 4. The limiting sleeve 5 can slide up and down along the axial direction of the lower extension rod 4, and can also rotate slightly around the lower extension rod 4. This structural design allows the subsequent cleaning rod 7 to adapt to road cracks of different depths and angles. A hinge frame 6 is hinged to the bottom end of the limiting sleeve 5 via a pin. The hinge frame 6 consists of two symmetrically arranged metal rods. The top ends of the two metal rods are connected to the limiting sleeve 5 via pins, and the bottom ends are welded together to fix the cleaning rod 7. The cleaning rod 7 is a flat metal rod with a sharpened bottom edge and a wear-resistant ceramic coating. It can efficiently scrape away hard impurities such as stones and solidified oil stains from cracks, while extending the service life of the cleaning rod 7. In actual operation, the hinge frame 6 can automatically adjust its opening angle according to the crack width, ensuring that the cleaning rod 7 always fits against the inner wall of the crack, ensuring thorough cleaning without any blind spots.

[0025] like Figure 2 and Figure 4 As shown, a conveying cylinder 8 is slidably connected to the mounting block 3. The conveying cylinder 8 has a cylindrical hollow structure and can reciprocate on the mounting block 3. A liquid delivery slot 9 is provided on the surface of the conveying cylinder 8. The liquid delivery slot 9 is a long rectangular slot and is completely located inside the mixing chamber. When the conveying cylinder 8 moves up and down, the liquid delivery slot 9 can guide the cleaning liquid in the mixing chamber into the conveying cylinder 8. A drain trough 10 is provided at the bottom of the conveying cylinder 8. The drain trough 10 consists of multiple evenly distributed circular holes. After the cleaning liquid enters the conveying cylinder 8 through the liquid delivery slot 9, it can be evenly sprayed into the road cracks through the drain trough 10. Combined with the scraping action of the cleaning rod 7, cleaning and sanitation are carried out simultaneously.

[0026] A connecting sleeve 11 is welded and fixed to the top of the conveying cylinder 8. The connecting sleeve 11 is an annular metal sleeve, the inner diameter of which matches the outer diameter of the conveying cylinder 8, and is used to connect the conveying cylinder 8 to the transmission structure. A rotating shaft 12 is arranged inside the mounting cylinder 1 along its axial direction. One end of the rotating shaft 12 is rotatably connected to the end of the mounting cylinder 1 away from the cover plate 2 through a bearing, and the other end extends into the mixing chamber and is fixedly installed with a mixing block 13. A diversion groove 15 is opened on the outer side of the mixing block 13. The diversion groove 15 is a spiral groove. When the mixing block 13 rotates with the rotating shaft 12, the diversion groove 15 can stir the cleaning liquid in the mixing chamber, prevent the effective components in the cleaning liquid from settling, and ensure uniform and stable cleaning effect.

[0027] An eccentric rod 14 is rotatably connected to the mixing block 13 via a pin. One end of the eccentric rod 14 is offset from the rotation center of the mixing block 13 and extends to the outside of the connecting sleeve 11, where it is rotatably connected via a pin. A motor 16 for driving the rotating shaft 12 is fixedly mounted on one end of the mounting cylinder 1 via a motor bracket. The motor 16 is a small DC geared motor, and its output shaft is fixedly connected to the end of the rotating shaft 12 away from the mixing block 13 via a coupling. The motor 16 can be connected to an external power source via a wire or powered by a battery compartment on the mounting cylinder 1 to meet the needs of outdoor operations.

[0028] In addition, a sealing block 17 is provided at the top of the mixing chamber. The sealing block 17 is made of rubber, and its outer wall is press-fitted with the inner wall of the mounting cylinder 1 to prevent the cleaning fluid in the mixing chamber from leaking. A through hole is provided on the sealing block 17, which can be used to add cleaning fluid into the mixing chamber. After adding the cleaning fluid, it can be sealed with a rubber plug to ensure the airtightness of the mixing chamber.

[0029] The specific working principle is as follows: When using this road crack pretreatment and cleaning device, open the rubber plug on the sealing block 17, and inject an appropriate amount of cleaning fluid into the mixing chamber through the through hole. Select the corresponding type of cleaning fluid according to the degree of crack contamination. For example, use an oil-removing cleaning fluid for oil stains and a neutral rinsing fluid for salt stains. After injection, seal the through hole with the rubber plug to prevent the cleaning fluid from leaking.

[0030] The operator holds the installation cylinder 1 or mounts it on the traction equipment, aligns the cleaning rod 7 with the road crack to be treated, and adjusts the position of the limiting sleeve 5 on the lower extension rod 4 according to the crack depth so that the cleaning rod 7 can penetrate into the crack. At the same time, the self-adjustment of the hinge frame 6 ensures that the cleaning rod 7 fits the inner wall of the crack.

[0031] The motor 16 is started, and the output shaft of the motor 16 drives the rotating shaft 12 to rotate, which in turn drives the mixing block 13 to rotate. On the one hand, the diversion groove 15 on the outside of the mixing block 13 stirs the cleaning liquid in the mixing chamber to prevent the effective ingredients from settling; on the other hand, when the mixing block 13 rotates, the eccentric rod 14 connected to it makes a circular motion. Since the other end of the eccentric rod 14 is connected to the connecting sleeve 11, and the conveying cylinder 8 can only slide along the axial direction of the mounting block 3, the circular motion of the eccentric rod 14 is converted into the up-and-down reciprocating motion of the conveying cylinder 8 along the mounting block 3.

[0032] When the conveying cylinder 8 moves upward, the liquid delivery port 9 is fully exposed inside the mixing chamber, and the cleaning liquid in the mixing chamber enters the interior of the conveying cylinder 8 through the liquid delivery port 9. When the conveying cylinder 8 moves downward, the liquid delivery port 9 is partially or completely blocked by the mounting block 3, and the cleaning liquid inside the conveying cylinder 8 is evenly sprayed into the crack through the drain trough 10 at the bottom. At the same time, the mounting cylinder 1 moves along the length of the crack, and the cleaning rod 7 moves with the device inside the crack, continuously scraping away impurities such as oil, stones, and salt crystals. The sprayed cleaning liquid can rinse the inner wall of the crack after scraping, carrying away residual fine contaminants, achieving simultaneous scraping and rinsing, and significantly improving the cleaning effect.

[0033] After a crack is cleaned, turn off motor 16. If further work is required, the cleaning fluid in the mixing chamber can be added before continued use. If the work is completed, the cover plate 2 can be removed to clean the mixing chamber, conveying cylinder 8 and other components for future use.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
