Description

Technical Field

[0001] This invention relates to the field of road repair equipment technology, specifically a road repair device for highway bridge maintenance. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. It is commonly used for the paving and hardening of highways and bridges. Over long-term use, coupled with harsh environmental conditions, asphalt pavement has developed problems such as potholes and cracks. In particular, for highways with high traffic volume and heavy vehicle traffic, the pavement is constantly subjected to the heavy pressure of vehicles, which often leads to cracks, potholes, unevenness, and other defects. This significantly affects the service life of the highway and the safe driving of vehicles. Furthermore, the damaged sections of highways and bridges also pose significant safety hazards to pedestrians and surrounding buildings.

[0003] When maintaining and repairing hardened road surfaces such as highways or bridges, small-scale repairs are generally done manually. Workers pour asphalt-aggregate mixture onto the area to be repaired and maintained, then heat it to increase its fluidity, and then use rollers to flatten and shape it. However, after this repair method is completed, because workers cannot accurately control the amount of repair material, the height of the repaired area is inconsistent with other areas, resulting in the problem that the repaired area is locally too high or too low, which greatly affects the passage of vehicles and pedestrians. Furthermore, the raised or sunken parts can also pose significant safety hazards in poor lighting conditions or when there is water accumulation on the road surface. Therefore, those skilled in the art have proposed a road surface repair device for highway and bridge maintenance to solve the above-mentioned technical problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a road surface repair device for highway bridge maintenance, which solves the problem that existing manual repair methods often result in uneven heights between repaired areas and other areas.

A drive motor is fixedly connected to the middle of the bottom end of the partition, and the output end of the drive motor is connected to the middle of the top end of the connecting seat.

[0013] Preferably, the pit cleaning mechanism further includes an exhaust port, an exhaust port is provided in the middle of the rotating disk, multiple exhaust slots are provided at equal intervals around the middle of the partition, and a fan is provided in the middle of the top of the inner side of the mounting barrel.

[0014] Preferably, the model filling mechanism includes a mounting barrel three, with the mounting barrel three fixedly connected to the end of the second connecting rod away from the mounting base plate. A silicone rubber diaphragm is provided at the bottom of the mounting barrel three, and a sliding sealing ring is provided at the bottom of the outer wall of the mounting barrel three for fixing and sealing the silicone rubber diaphragm at the bottom of the mounting barrel three. A sealing plate is provided in the middle of the inner side of the mounting barrel three, and an air chamber is formed between the sealing plate and the silicone rubber diaphragm. An air pump is provided on one side of the outer wall of the mounting barrel three, and the outlet of the air pump is connected to the interior of the air chamber through a connecting pipe.

[0015] Preferably, the model filling mechanism further includes a filling tank, which is located at the bottom center of the mounting base plate. An asphalt insulation conveying pump is located at the upper inner side of the mounting barrel three. The inlet of the asphalt insulation conveying pump is connected to the bottom center of the filling tank via a connecting pipe. The outlet of the asphalt insulation conveying pump is connected to the interior of the air filling chamber via a connecting pipe. A one-way valve is provided on the connecting pipe connecting the asphalt insulation conveying pump and the outlet.

[0016] Preferably, the end-processing mechanism includes a mounting barrel, and the mounting barrel is fixedly connected to the end of the third connecting rod away from the mounting base plate. An outer ring diverter seat is provided in the lower middle part of the outer wall of the mounting barrel, and multiple flame guns are arranged in a circumferential array at the bottom center of the outer ring diverter seat.

[0017] Preferably, the end-processing mechanism further includes a stabilizing sleeve, which is fixedly connected to the inner center of the first mounting barrel. A second hydraulic cylinder is installed inside the stabilizing sleeve, and the bottom end of the cylinder body of the second hydraulic cylinder is connected to the top center of the inner wall of the first mounting barrel. A flattening seat is slidably connected inside the first mounting barrel, and the top center of the flattening seat is connected to the top end of the rod of the second hydraulic cylinder.

[0018] Working Principle: When maintaining the road surface of a highway bridge, the worker moves the device to the location of the pothole to be repaired, and then activates the switching mechanism. First, the hydraulic cylinder on the bottom ring seat is activated, and its internal rod extends. Simultaneously, the rod of the hydraulic cylinder pushes the bottom support pad into contact with the ground, raising the entire device and securing it to the road surface. Then, the drive motor on the mounting frame is activated, causing its shaft to rotate synchronously with the mounting base. Simultaneously, the mounting base rotates synchronously with the adjusting ring seat in the top ring seat, and also rotates the connecting rod and corresponding mounting bucket. Once the mounting bucket is rotated to the location of the pothole to be repaired on the road or bridge, rotation stops, thus beginning the first step of highway bridge road surface repair. This completes the initial drive and function switching of the entire device before use. When the second installation bucket is moved to the location of the pit to be repaired on the highway bridge, the pit cleaning mechanism is activated. First, the drive motor on the partition starts, and at the same time, the shaft on the drive motor drives the connecting seat at the bottom to rotate. At the same time, the connecting seat drives the rotating disk at the bottom of the second installation bucket to rotate. At the same time, the rotating disk drives the cleaning brush roller on it to rotate synchronously in the pit. While rotating, the cleaning brush roller sweeps the gravel in the pit out of the pit, thus facilitating subsequent repair work. At the same time, the fan in the second installation bucket starts synchronously. The air force discharged by the fan enters the upper part of the rotating disk through the exhaust duct on the partition, and then the air force entering the upper part of the rotating disk is discharged to the center of the pit through the exhaust port on the rotating disk. Thus, while the cleaning brush roller sweeps the gravel in the pit, it can also assist in the discharge of gravel out of the pit, and can also clean the loose soil in the pit, thus facilitating the subsequent bonding of the repair filler. This completes the cleaning treatment before the pit repair.After cleaning the gravel and loose soil in the pit, the drive switching mechanism is restarted, rotating and adjusting the installation bucket three to the top position of the pit. Then, the model filling mechanism is activated. First, the workers install the silicone rubber diaphragm at the bottom of the installation bucket three and secure it with the sliding sealing ring on the bucket three. After installation, the workers adjust the overall position of the installation bucket three so that the silicone rubber diaphragm at the bottom of the bucket three adheres to the road surface. Then, the air pump on the installation bucket three is started, and the air pump injects gas into the inflation chamber through the connecting pipe. The gas in the inflation chamber is prevented from overflowing by a one-way valve, ensuring that the gas only causes the silicone rubber diaphragm of the mounting bucket (3) to deform against the ground. The deformed diaphragm conforms to the shape of the pit's inner wall, creating a perfectly fitted model. Then, the asphalt insulation pump for mounting bucket (3) is activated, drawing the asphalt mixture from the filling tank at the bottom of the mounting base through a connecting pipe and discharging it into the model formed by the deformed silicone rubber diaphragm. Then, the asphalt mixture is injected... After the model formed by the silicone rubber diaphragm is filled, the filling process is stopped. Then, the operator slides the sliding sealing ring on the third mounting bucket upwards, releasing the sealing ring from its limiting and fixing position on the silicone rubber diaphragm, thus completing the model filling process. After the model formed by the silicone rubber diaphragm is completely filled, the drive switching mechanism is restarted, rotating and adjusting the first mounting bucket to the top position of the pit. Then, the end-processing mechanism is activated. First, the flame gun on the outer ring distributor sprays flames. The flames sprayed by the flame gun ignite the silicone rubber diaphragm that is in contact with the inside of the pit. The process involves heating and melting the filler material, which then bonds it better to the pit's inner wall. Simultaneously, the flame from the blowtorch heats the asphalt mixture filler material within the mold formed by the silicone rubber diaphragm, increasing its fluidity. Then, the second hydraulic cylinder within the stabilizing sleeve is activated. As the second cylinder activates, its rod extends, simultaneously moving the flattening seat within the first mounting bucket downwards. This downward movement of the flattening seat flattens and compacts the asphalt mixture filler material within the pit, thus completing the final finishing work after pit repair.

[0019] The present invention has the following beneficial effects:

[0020] 1. By adding and setting a drive switching mechanism, this invention allows for the switching of several different mechanisms according to the repair process when repairing road or bridge surfaces. This improves the overall efficiency of the equipment in repairing road or bridge surfaces and avoids problems such as poor repair accuracy and high workload caused by manual adjustment by workers. It also facilitates large-scale and continuous pothole repair operations.

[0021] 2. This invention, by adding and setting a pothole cleaning mechanism, cleans potholes on highways or bridges before repairing them. This not only effectively removes loose material, water, and other debris from the potholes, providing a clean base for subsequent repair work, but also improves the adhesion between the repair material and the original road surface, extending the service life of the repair effect. Furthermore, it significantly reduces the occurrence of peeling and cracking after repair. Through this treatment method, the overall quality and durability of highways and bridges are significantly improved, thereby reducing subsequent maintenance costs and traffic safety hazards.

[0022] 3. By adding and setting a model filling mechanism, this invention, when repairing potholes on highways or bridges, firstly forms an inner wall model that perfectly fits the inner wall of the pothole by deforming a silicone rubber diaphragm. Then, the inner wall model formed by the silicone rubber diaphragm is used to fill the pothole with repair filler. This method can not only effectively control the amount of repair filler used and reduce waste of repair filler during the road repair process, but also avoid local bulges or depressions around the pothole after the repair is completed by using the inner wall model. This ensures the flatness of the repair position and improves the safety of pedestrians or vehicles passing through.

[0023] 4. By adding and setting an end-processing mechanism, this invention can, on the one hand, melt the silicone rubber diaphragm model that is in contact with the inner wall of the pit by the flame of the blowtorch, thereby improving the bonding stability between the outer wall of the model and the inside of the pit. On the other hand, the flame of the blowtorch can also heat up the asphalt repair filler in the pit, thereby improving its fluidity, which not only facilitates its adhesion to the pit, but also facilitates subsequent flattening and compaction.

[0034] The technical solutions in 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.

[0035] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides a road surface repair device for highway bridge maintenance, including a bottom ring seat 1, which serves as the basic component of the overall device and is used to assemble and support various processing mechanisms and their subordinate structural components.

[0036] Please see the appendix Figure 3 The drive switching mechanism is located in the middle of the inner side of the bottom ring seat 1 and is used to switch the functions of other mechanisms of the overall drive device.

[0037] The drive switching mechanism includes a top ring seat 12, a bottom ring seat 1, and an adjusting ring seat 8. A mounting base 9 is provided on the upper inner side of the bottom ring seat 1, and the outer walls of the mounting base 9 are connected to the corresponding positions on the inner side of the adjusting ring seat 8 via rods. Three connecting rods 7 are fixedly connected at equal intervals on the outer walls of the mounting base 9. A mounting frame 11 is fixedly connected to the top center of the top of the top ring seat 12, and a drive motor 10 is provided on the inner center of the mounting frame 11. The output end of the drive motor 10 is connected to the center of the mounting base 9. Multiple hydraulic cylinders 13 are arranged in a circular array on the top center of the bottom ring seat 1, and the rods of the hydraulic cylinders 13 penetrate the bottom ring seat 1 and extend downward. Support pads 15 are provided at the bottom ends of the rods of the hydraulic cylinders 13.

[0038] When the drive switching mechanism is started, the hydraulic cylinder 13 on the bottom ring seat 1 is activated first. After activation, the rod inside the hydraulic cylinder 13 extends, and at the same time, the rod of the hydraulic cylinder 13 drives the support pad 15 at its bottom to contact the ground. Simultaneously, as the rod of the hydraulic cylinder 13 extends, the entire device is raised and supported and fixed on the road surface.

[0039] Then the drive motor 10 on the mounting frame 11 is started. At the same time as the drive motor 10 starts, its shaft drives the mounting base 9 to rotate synchronously. At the same time as the mounting base 9 rotates, it drives the adjusting ring seat 8 in the top ring seat 12 to rotate synchronously. At the same time as the mounting base 9 rotates, it also drives the connecting rod 7 and the corresponding mounting bucket to rotate. When the mounting bucket 6 is rotated to the position of the pothole that needs to be repaired on the road or bridge, the rotation stops, thus starting the first step of the road and bridge road surface repair. This completes the drive and function switching processing of the whole device before use.

[0040] Please see the appendix Figure 4 - Appendix Figure 5 The pit cleaning mechanism is located inside the bottom ring seat 1 on one side near the edge, and is used to clean the dust and debris inside the road pit.

[0041] The pit cleaning mechanism includes a second mounting bucket 6. The second mounting bucket 6 is fixedly connected to the end of the first connecting rod 7 away from the mounting base plate 9. The bottom end of the second mounting bucket 6 is rotatably connected to a rotating disk 14. The bottom end of the rotating disk 14 has a circumferential array of multiple cleaning brush rollers 5 near the edge. A partition 20 is fixedly connected to the middle of the inner side of the second mounting bucket 6. A connecting seat 24 is fixedly connected to the middle of the top end of the rotating disk 14. A drive motor 22 is fixedly connected to the middle of the bottom end of the partition 20, and the output end of the drive motor 22 is connected to the middle of the top end of the connecting seat 24.

[0042] When the pit cleaning mechanism is started, the drive motor 22 on the partition 20 is started first. At the same time as the drive motor 22 starts, its shaft drives the bottom connecting seat 24 to rotate. At the same time as the connecting seat 24 rotates, it drives the bottom rotating disk 14 to rotate on the mounting bucket 6. At the same time as the rotating disk 14 rotates, it drives the cleaning brush roller 5 on it to rotate synchronously in the pit. At the same time as the cleaning brush roller 5 rotates, it sweeps the gravel in the pit out of the pit, thus facilitating subsequent repair work.

[0043] The pit cleaning mechanism also includes an exhaust port 23. An exhaust port 23 is provided in the middle of the rotating disk 14. Multiple ventilation slots 21 are provided at equal intervals around the middle of the partition 20. A fan 19 is provided in the middle of the top of the inner side of the mounting barrel 6.

[0044] Simultaneously, the blower 19 inside the second barrel 6 is started synchronously. The air force discharged by the blower 19 enters the upper part of the rotating disk 14 through the exhaust duct 21 on the partition 20. Then, the air force entering the upper part of the rotating disk 14 is discharged to the center of the pit through the exhaust port 23 on the rotating disk 14. Thus, while the cleaning brush roller 5 sweeps the debris in the pit, it can also assist in the discharge of debris outside the pit and clean out the loose soil in the pit, which facilitates the subsequent bonding operation of the repair filler. This completes the cleaning treatment before the repair in the pit.

[0045] Please see the appendix Figure 6 - Appendix Figure 7 The model filling mechanism is located inside the bottom ring seat 1 on one side near the edge. It is used to create a pit model of the road surface pit cleaned by the pit cleaning mechanism and fill it according to the model shape.

[0046] The model filling mechanism includes a mounting barrel 16. The mounting barrel 16 is fixedly connected to the end of the second connecting rod 7 away from the mounting base plate 9. A silicone rubber diaphragm 25 is provided at the bottom of the mounting barrel 16. A sliding sealing ring 26 is provided at the bottom of the outer wall of the mounting barrel 16 to fix and seal the silicone rubber diaphragm 25 at the bottom of the mounting barrel 16. A sealing plate 29 is provided in the middle of the inner side of the mounting barrel 16. An air chamber 27 is formed between the sealing plate 29 and the silicone rubber diaphragm 25. An air pump 17 is provided on one side of the outer wall of the mounting barrel 16. The outlet of the air pump 17 is connected to the inside of the air chamber 27 through a connecting pipe.

[0047] When the model filling mechanism is started, the staff first installs the silicone rubber diaphragm 25 at the bottom of the installation bucket 3 16 and fixes it with the sliding sealing ring 26 on the installation bucket 3 16. After installation, the staff adjusts the overall position of the installation bucket 3 16 so that the silicone rubber diaphragm 25 at the bottom of the installation bucket 3 16 fits into the road surface.

[0048] Then, the air pump 17 on the installation barrel 3 16 is started. The air pump 17 injects gas into the inflation chamber 27 through the connecting pipe. The gas in the inflation chamber 27 is prevented from overflowing by the one-way valve 28, so that the gas in the inflation chamber 27 can only cause the silicone rubber diaphragm 25 of the installation barrel 3 16 to deform in contact with the ground. After deformation, the silicone rubber diaphragm 25 conforms to the shape of the inner wall of the pit, thus forming a model that perfectly fits the pit through the deformation of the silicone rubber diaphragm 25.

[0049] The model filling mechanism also includes a filling tank 4. The filling tank 4 is located at the bottom center of the mounting base plate 9. An asphalt insulation conveying pump 30 is located at the upper inner side of the mounting barrel 3 16. The inlet of the asphalt insulation conveying pump 30 is connected to the bottom center of the filling tank 4 through a connecting pipe. The outlet of the asphalt insulation conveying pump 30 is connected to the interior of the air chamber 27 through a connecting pipe. A one-way valve 28 is installed on the connecting pipe connecting the asphalt insulation conveying pump 30 and the outlet.

[0050] Then, the asphalt insulation conveying pump 30 of the installation bucket 16 is started. The asphalt insulation conveying pump 30 pumps the asphalt mixture filler in the filling box 4 at the bottom of the installation base plate 9 through the connecting pipe and discharges it into the mold formed by the deformed silicone rubber diaphragm 25. After the asphalt mixture filler fills the mold formed by the silicone rubber diaphragm 25, the filling is stopped. Then, the operator slides the sliding sealing ring 26 on the installation bucket 16 upward, so that the sliding sealing ring 26 releases the limiting fixation of the silicone rubber diaphragm 25, thereby completing the mold filling process.

[0051] Please see the appendix Figure 8 - Appendix Figure 9 The end-of-life treatment mechanism is located inside the bottom ring seat 1 on one side near the edge, and is used to perform final treatment on the road surface repaired by the model filling mechanism.

[0052] The end-of-life processing mechanism includes a mounting barrel 3. The mounting barrel 3 is fixedly connected to the end of the third connecting rod 7 away from the mounting base plate 9. An outer ring diverter seat 2 is provided in the lower middle part of the outer wall of the mounting barrel 3. Multiple flame guns 31 are arranged in a circular array at the bottom center of the outer ring diverter seat 2.

[0053] The main chain of silicone rubber is composed of alternating silicon and oxygen elements, and organic groups are usually added to improve its processing and properties. However, at high temperatures, both the main chain and organic groups of silicone rubber undergo breakage and slight chemical changes, leading to increased irregularity in the silicone rubber structure. This causes the silicone rubber molecular chains to intertwine or become entangled, making it more compact and viscous. Furthermore, silicone rubber readily absorbs moisture, forming a moisture interface layer. At high temperatures, moisture accelerates the chemical reactions in silicone rubber, further increasing its viscosity.

[0054] Furthermore, silicone rubber undergoes various chemical reactions at high temperatures, the most common being the breaking of silane bonds and the loss of crosslinking points. Silane bonds are chemical bonds on the silicone rubber molecular chain, and their strength and number directly affect the thermal stability and aging resistance of silicone rubber. When silane bonds break, the silicone rubber molecular chain is disrupted, leading to a decrease in its physical properties and chemical stability. The loss of crosslinking points makes the silicone rubber loose and increases the amount of gel-like substances, thus causing the silicone rubber to become more viscous at high temperatures. Therefore, molten silicone rubber can increase the strength and stability of the adhesion between asphalt repair filler and the inner wall of the pit.

[0055] When the end-of-line processing mechanism is started, the flame gun 31 on the outer ring diverter seat 2 first sprays out flames. The flames sprayed by the flame gun 31 heat and melt the silicone rubber diaphragm 25 that is in contact with the inside of the pit, thereby making the filler in the pit more bonded to the inner wall of the pit. On the other hand, the flames sprayed by the flame gun 31 can also heat up the asphalt mixture filler in the model generated by the silicone rubber diaphragm 25, thereby improving its fluidity.

[0056] The end-of-life processing mechanism also includes a stabilizing sleeve 32. The stabilizing sleeve 32 is fixedly connected to the middle of the inner side of the mounting barrel 3. A hydraulic cylinder 33 is installed inside the stabilizing sleeve 32. The bottom end of the cylinder body of the hydraulic cylinder 33 is connected to the middle of the top end of the inner wall of the mounting barrel 3. A flattening seat 34 is slidably connected inside the mounting barrel 3. The middle of the top end of the flattening seat 34 is connected to the top end of the rod of the hydraulic cylinder 33.

[0057] Then, the hydraulic cylinder 2 33 inside the stabilizing sleeve 32 is started. At the same time as the hydraulic cylinder 2 33 is started, its rod is pushed out. As the hydraulic cylinder 2 33 is pushed out, it drives the flattening seat 34 inside the mounting bucket 3 to move down. As the flattening seat 34 moves down, it flattens and compacts the asphalt mixture filling material in the pit, thus completing the end treatment work after the pit repair.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
