Abstract

This application discloses an integrated rapid paving equipment for airport pavement repair materials, belonging to the field of airport pavement repair technology. It includes a vehicle-mounted platform, a first skirt, a second skirt, a milling device, a drilling device, a curing system, a negative pressure collection system, a paving device, and a control center. This application establishes a dual dust constraint mechanism. Before the repair material is injected, the repair area covered by the first skirt undergoes temperature and humidity pretreatment to prevent premature solidification of the repair material upon contact with a cold, damp substrate. After the repair material is injected, the temperature and humidity within the enclosed space are maintained at a constant temperature and humidity, allowing the surface and interior of the repair material to solidify simultaneously. The enclosed space formed by the first skirt acts as a secondary dust barrier during the construction phase and transforms into a temperature and humidity curing chamber during the curing phase, achieving closed-loop spatial control throughout the entire single-point repair process.

Description

Technical Field

[0001] This application relates to the field of airport pavement repair technology, and in particular to an integrated device for rapid paving of airport pavement repair materials. Background Technology

[0002] During use, airport pavements inevitably suffer from potholes, cracks, and sandblasting due to the impact of aircraft takeoffs and landings and environmental erosion. Because of the unique nature of airport operations, pavement repairs can only be completed within a very limited downtime window (usually only 4-6 hours), placing extremely stringent demands on the efficiency of repair equipment and the quality of construction.

[0003] In existing technologies, pavement repair equipment is mostly large-scale and not suitable for small-scale, localized defects. For these defects, manual repair is often used, which has limited efficiency and quality. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an integrated equipment for rapid paving of airport pavement repair materials, which can solve the treatment of local pavement defects while taking into account both repair efficiency and quality.

[0005] An integrated rapid paving equipment for airport pavement repair materials according to an embodiment of this application includes: In-vehicle platform; The first skirt includes multiple skirt units, which are connected end to end to form a circumferentially closed fence structure. Each skirt unit is independently connected to the bottom of the vehicle platform and can actively rise and fall relative to the vehicle platform. When the first skirt is lowered to contact the road surface, it together with the bottom of the vehicle platform and the road surface defines the enclosing space. The second skirt is connected to the bottom of the vehicle platform and located inside the first skirt, and the second skirt encloses and defines the work space; A milling device is connected to the bottom of the vehicle platform and located inside the second skirt. The milling device is capable of being raised and lowered relative to the vehicle platform. The milling device includes a rotating milling drum and a milling cover surrounding the rotating milling drum. A drilling device is connected to the bottom of the vehicle platform and located inside the second skirt, and the drilling device is capable of being raised and lowered relative to the vehicle platform; A maintenance system is installed on the vehicle platform and communicates with the surrounding space. The maintenance system is configured to adjust the temperature and humidity within the surrounding space when the first skirt is lowered to contact the pavement. A negative pressure collection system is installed on the vehicle platform, and the negative pressure collection system is connected to the surrounding space, the working space, and the milling cover.

[0006] The integrated rapid paving equipment for airport pavement repair materials according to the embodiments of this application has at least the following beneficial effects: This application utilizes a double-skirt structure consisting of a first skirt and a second skirt to create a two-tiered enclosed space at the bottom of the vehicle platform. The milling and drilling devices are located within the working space defined by the second skirt. Debris and dust generated during operation are first confined within this working space and then simultaneously drawn in by a negative pressure collection system via the milling cover and the working space. Fine dust diffusing outside the working space is further blocked by the enclosing space defined by the first skirt and is completely removed from the enclosing space by the negative pressure collection system, forming a dual dust confinement mechanism. Before the repair material is injected, the control center controls the curing system to pre-treat the repair area covered by the first skirt to prevent premature solidification of the repair material upon contact with a cold, damp substrate. After the repair material is injected, the vehicle platform moves again to cover the repair area with the first skirt, and the curing system adjusts the temperature and humidity within the enclosing space for constant temperature and humidity curing, ensuring simultaneous curing of the surface and interior of the repair material. The enclosed space formed by the first skirt serves as a secondary dust barrier during the construction phase and transforms into a temperature and humidity curing chamber during the curing phase. This achieves closed-loop spatial control of the entire process of single-point repair, making it suitable for rapid and high-quality repair of local defects in pavement panels.

[0023] Reference Figures 1 to 6 This application proposes an integrated equipment for rapid paving of airport pavement repair materials, including a vehicle-mounted platform 100, a first skirt 101, a second skirt 102, a milling device 200, a drilling device 300, a maintenance system, a negative pressure collection system, a paving device 400, and a control center.

[0024] The first skirt 101 includes multiple skirt units 1011, which are connected end-to-end to form a circumferentially closed fence structure. Each skirt unit 1011 is independently connected to the bottom of the vehicle platform 100 and can actively rise and fall relative to the vehicle platform 100. When the first skirt 101 is lowered to contact the pavement, it, together with the bottom of the vehicle platform 100 and the pavement, defines an enclosed space. The second skirt 102 is connected to the bottom of the vehicle platform 100 and located inside the first skirt 101, and the second skirt 102 encloses and defines a working space.

[0025] A milling device 200 is connected to the bottom of the vehicle platform 100 and located within the second skirt 102. The milling device 200 is movable relative to the vehicle platform 100. The milling device 200 includes a rotary milling drum 201 and a milling cover 202 covering the outer periphery of the rotary milling drum 201. A drilling device 300 is connected to the bottom of the vehicle platform 100 and located within the second skirt 102. The drilling device 300 is movable relative to the vehicle platform 100.

[0026] The maintenance system is located on the vehicle platform 100 and communicates with the surrounding space. The maintenance system is configured to regulate the temperature and humidity within the surrounding space when the first skirt 101 is lowered to contact the pavement. The negative pressure collection system is located on the vehicle platform 100 and communicates with the surrounding space, the working space, and the milling cover 202.

[0027] The paving device 400 is connected to one side of the vehicle platform 100 and is used to inject repair material into the repair area. The control center is connected to the first skirt 101, the milling device 200, the drilling device 300, the curing system, the negative pressure collection system and the paving device 400, and is configured to control the curing system to adjust the temperature and humidity of the repair area before and after the material is injected, according to the paving requirements.

[0028] In this embodiment, a two-level enclosed space is formed by a double-skirt structure. The milling device 200 and the drilling device 300 are located within the working space defined by the second skirt 102. During operation, debris and dust are first confined within the working space and are simultaneously drawn and collected by the negative pressure collection system via the milling cover 202 and the working space. Fine dust that diffuses outside the working space is further blocked and removed by the enclosing space defined by the first skirt 101. Before the repair material is injected, the control center controls the maintenance system to perform temperature and humidity pretreatment on the repair area covered by the first skirt 101. After the repair material is injected, the vehicle platform 100 moves again to cover the repair area with the first skirt 101, and the maintenance system performs constant temperature and humidity maintenance.

[0029] Combination Figure 1 and Figure 5 In some embodiments of this application, the skirt unit 1011 includes a lifting drive unit and a flexible sheet 1013. The lifting drive unit is provided with a lifting rod 1012, and the flexible sheet 1013 is fixedly connected to the lifting rod 1012 and extends to both sides of the lifting rod 1012 along the enclosing direction. The flexible sheet 1013 is configured to have an elastically deformable structure, and the flexible sheets 1013 between two adjacent skirt units 1011 are connected and fixed.

[0030] Understandably, the connection and fixation of the flexible sheet 1013 creates a continuous and closed enclosure between adjacent skirt units 1011. When the vehicle platform 100 is stationary on the pavement, and the pavement has certain undulations or unevenness, the flexible sheet 1013 can adapt to the local unevenness of the pavement through elastic deformation, ensuring good contact and sealing between the bottom of the first skirt 101 and the pavement, and avoiding leakage gaps caused by uneven pavement. The lifting rod 1012 drives the flexible sheet 1013 to rise and fall as a whole, realizing the active retraction and extension of the first skirt 101.

[0031] The flexible sheet 1013 is configured to undergo elastic deformation. When the lifting drive units of the two skirt units 1011 perform different lifting operations, the flexible sheet 1013 can elastically deform to avoid damage. Simultaneously, when the lifting drive unit operates, it also helps reduce the resistance caused by the flexible sheet 1013, making the operation of the lifting drive unit smoother and its lifespan longer. Using the flexible sheet 1013 to connect the two skirt units 1011 also helps reduce the number of lifting drive units and, on this basis, allows for compatible connections between the skirt units 1011.

[0032] It is understandable that the lifting drive unit can adopt a linear motor, telescopic cylinder, or other drive methods. The lifting rod 1012 is the lifting drive end of the lifting drive unit. It can be connected to the lifting drive unit as a whole, such as by directly using the extension of the shaft of the telescopic cylinder as the lifting rod 1012. Alternatively, it can be connected and fixed by splicing, such as by connecting the lifting rod 1012 to the moving end of the linear motor.

[0033] The flexible sheet 1013 can be made of EPDM or other materials that meet the requirements.

[0034] In some embodiments, the flexible sheet 1013 is defined as a wavy structure along its length, so that in the case of uneven pavement, especially when there are height differences in the pavement around the perimeter, the wavy structure can be used to provide sufficient deformation margin and keep the flexible sheet 1013 as close as possible to the bottom pavement.

[0035] Combination Figure 5 In some embodiments of this application, a reinforcing strip 1014 is provided at the bottom of the flexible sheet 1013 in a direction away from the lifting rod 1012, and the thickness of the reinforcing strip 1014 is increased. The flexible sheet 1013 is provided with a plurality of reinforcing tips 1015, which are cross-shaped, and the thickness of the reinforcing tips 1015 gradually decreases from the center to the edge.

[0036] Understandably, the reinforcing strip 1014 extends along the bottom of the flexible sheet 1013 and gradually thickens in the direction away from the lifting rod 1012. This enhances the supporting rigidity of the bottom edge when the flexible sheet 1013 presses against the pavement, preventing warping deformation of the bottom of the flexible sheet 1013 upon contact with the pavement. The cross-shaped reinforcing tip 1015 gradually decreases in thickness from the center to the edge, allowing the reinforcing tip 1015 to adapt to the pavement contour with the center as a fulcrum when subjected to pressure from local pavement protrusions, further improving the skirt's ability to seal against uneven pavement surfaces. Furthermore, the reinforcing tip 1015 also provides material allowance when the flexible sheet 1013 is stretched, preventing frequent stretching and breakage of the flexible sheet 1013.

[0037] It should be noted that both the reinforcing strip 1014 and the reinforcing tip 1015 are integrally formed with the flexible sheet 1013.

[0038] Combination Figure 2 , Figure 3 In some embodiments of this application, the vehicle platform 100 is provided with a lifting seat, and a second skirt 102 is provided on the periphery of the lifting seat. The milling device 200 and the drilling device 300 are both provided on the lifting seat. The bottom height of the second skirt 102 is higher than the bottom height of the milling device 200, so that when the milling device 200 contacts the pavement, a gap is maintained between the bottom of the second skirt 102 and the pavement.

[0039] With the structural configuration of this embodiment, when milling is required, the control centerline first controls the lowering of the lifting platform, causing the milling device 200 to contact the surface. At this time, there is still a gap between the second skirt 102 and the surface. If drilling is required, the drilling device 300 is lowered separately in this state. In this way, the stability of the lifting platform can be improved by using the milling device 200, ensuring the stable execution of drilling operations.

[0040] Understandably, a gap is maintained between the bottom of the second skirt 102 and the runner surface, ensuring that the working space is not completely enclosed but rather connected to the surrounding space through this gap. During milling and drilling operations, the second skirt 102 confines large debris within the working space, while fine dust can diffuse into the surrounding space through the bottom gap. This dust is then simultaneously drawn from both the surrounding and working spaces by the negative pressure collection system, achieving staged negative pressure collection. This helps to rationally distribute the working pressure of the negative pressure collection system. Simultaneously, the gap prevents direct friction damage between the bottom of the second skirt 102 and the runner surface, and also allows stones splashed during milling and drilling to pass through, preventing impact damage.

[0041] The material of the second skirt edge 102 can be the same as that of the first skirt edge 101. Since the second skirt edge 102 does not need to be adjusted independently along its length, other materials with relatively weak elasticity can also be used.

[0042] Combination Figure 4 In some embodiments of this application, along the milling direction, the milling cover 202 is provided with pressing parts 203 on both the front and rear sides of the rotating milling drum 201, and the pressing parts 203 are elastically pressed against the surface.

[0043] It is understandable that milling operations will cause some impact on the pavement. This embodiment effectively absorbs vibrations and prevents the pavement from loosening due to vibration by clamping the pavement from both the front and rear sides. At the same time, during the milling process, dust and gravel are mostly splashed to the front and rear sides. The front clamping part 203 clamps the pavement surface before the milling drum cuts into the pavement, and the rear clamping part 203 clamps the edge of the milled area after milling is completed. The front and rear clamping parts 203 clamp the working area of ​​the rotating milling drum 201 in the middle, forming a local seal, so that the milling debris is constrained in a small space between the milling cover 202 and the pavement the moment it is generated, which facilitates the efficient absorption and collection of the negative pressure collection system through the milling cover 202.

[0044] Combination Figure 4 Specifically, in some embodiments, the pressing part 203 includes a first mounting base 2031, a second mounting base 2033, and a pressure roller 2034. The first mounting base 2031 is fixedly mounted on the milling cover 202. The second mounting base 2033 is mounted below the first mounting base 2031 via a spring guide post 2032, thereby enabling it to move up and down relative to the first mounting base 2031 while applying downward pressure via the spring guide post 2032. The pressure roller 2034 is rotatably mounted on the bottom of the second mounting base 2033. During operation, when the lifting seat descends, the pressure roller 2034 abuts against the track surface and elastically abuts against the track surface under the action of the spring guide post 2032. A wear-resistant rubber layer may be provided on the surface of the pressure roller 2034.

[0045] In some embodiments of this application, the drilling apparatus 300 is provided with a drill bit and an air supply mechanism. The drill bit has an internal air passage connected to the air supply mechanism for discharging high-pressure gas from the head of the drill bit. The air supply mechanism has a first working position and a second working position, with the output pressure at the first working position being lower than the output pressure at the second working position. The control center is configured to activate the air supply mechanism during drilling and maintain it at the first working position, and to switch the air supply mechanism to the second working position upon completion of drilling.

[0046] Understandably, during drilling, the air supply mechanism delivers airflow to the drill bit head at a lower pressure in the first working position to cool the drill bit and blow drill chips out of the hole, preventing high-pressure airflow from interfering with drilling accuracy. After drilling is completed, the air supply mechanism switches to the second working position, using higher pressure to powerfully blow air towards the bottom of the hole, thoroughly removing any remaining dust. Both drilling cooling and chip removal, as well as hole cleaning, are achieved through the same air path, eliminating the need to change tools.

[0047] Specifically, in some embodiments, an air passage is provided on the drill bit shaft, and the air supply mechanism directly supplies air to the end of the drill bit through the air passage. During the drilling process, the drill chips can be pushed out along the chip removal groove of the drill bit, while also achieving a forced air cooling effect and a certain lubrication effect.

[0048] Combination Figure 1 In some embodiments of this application, the maintenance system includes an information acquisition unit, an airflow circulation module, a temperature control module, and a misting humidification module. The information acquisition unit is equipped with a humidity sensor and a temperature sensor, the airflow circulation module is equipped with an air supply channel, the temperature control module is located in the air supply channel and is used to regulate the air temperature in the air supply channel, and the misting humidification module is equipped with a mist atomizer.

[0049] During operation, the information acquisition unit collects the humidity and temperature of the surrounding space. The control center then uses the collected humidity and temperature data, along with the optimal construction conditions for the current repair materials, to adjust the temperature of the entire surrounding space using a combination of airflow circulation and temperature control modules, and to adjust the humidity of the entire surrounding space using a misting humidification module.

[0050] Before repairs, the pavement can be pre-treated to bring the area to be repaired to a suitable temperature and humidity level. For example, the pavement can be heated in winter, dried in the rainy season, and cooled in summer.

[0051] Combination Figure 3 , Figure 6 In some embodiments of this application, the maintenance system is further provided with a flow equalization pipe, which is distributed along the length direction of the first skirt 101. The flow equalization pipe is provided with multiple openable and closable openings, and the airflow circulation module and the atomizing humidification module are both connected to the flow equalization pipe.

[0052] Understandably, the flow equalization pipes are distributed along the length of the first skirt 101, allowing temperature and humidity-controlled airflow to be evenly delivered circumferentially throughout the surrounding space, preventing uneven curing of the repair material due to excessively high or low local temperatures and humidity. Multiple openable and closable openings can be selectively opened according to the specific location of the repair area, precisely delivering airflow to the area requiring maintenance.

[0053] Furthermore, in some embodiments of this application, the control center is also configured to control the opening to close when the milling device 200 and the drilling device 300 are operating, and to control the opening to open when the maintenance system is operating.

[0054] Understandably, during the milling and drilling phases, the openings remain closed to prevent dust from entering the distribution pipe and causing blockages. During the curing phase, the openings are opened, and the distribution pipe delivers temperature and humidity-controlled airflow into the enclosed space. Through time-based control of the openings, the air supply ducts of the curing system are effectively protected during the construction phase.

[0055] Combination Figure 6More specifically, in some embodiments, the flow equalization pipe includes an inner tube 501 and an outer tube 500 that are sleeved together, with the inner tube 501 movable and adjustable relative to the outer tube 500. Both the inner tube 501 and the outer tube 500 have through holes of the same size, forming an opening when aligned and closing when misaligned. The outer tube 500 is fixedly mounted relative to the vehicle platform 100, and the inner tube 501 has connecting lugs extending through it. A drive structure for connecting the connecting lugs is provided on the outer tube 500. Furthermore, multiple inner tubes 501 are provided within one outer tube 500, each inner tube 501 corresponding to an opening at a specific location.

[0056] Combination Figure 2 In some embodiments of this application, a loading platform is provided on one side of the vehicle-mounted platform 100, and the paving device 400 includes a material storage module and a paving execution mechanism. The material storage module is disposed on the loading platform and is used to store repair materials. The paving execution mechanism is placed on the loading platform and can be unloaded from the loading platform. The paving execution mechanism is connected to the material storage module and is used to pave the repair materials.

[0057] Understandably, the paving execution mechanism is unloaded from the loading platform during operation and can be flexibly moved to the repair area for material paving, without being restricted by the position of the vehicle-mounted platform 100. The material storage module is fixed to the loading platform and supplies repair materials to the paving execution mechanism through pipelines, ensuring a continuous supply of materials during the paving process. Furthermore, the paving execution mechanism operates independently, avoiding any impact on other structures on the vehicle-mounted platform 100, thus balancing construction flexibility with the overall stability of the equipment.

[0058] It should be noted that the material storage module and the paving execution mechanism can be set up with reference to existing technologies, and no specific limitations are made here.

[0059] In actual construction, for localized potholes and other defects in the pavement slab, the vehicle-mounted platform 100 first moves to the affected area, and the first skirt 101 descends to form an enclosing space in contact with the pavement surface. The control center then controls the maintenance system to pre-treat the base surface for temperature and humidity. Subsequently, the milling device 200 descends to mill and groove the damaged area, while the negative pressure collection system simultaneously extracts and collects debris and dust. If drilling and grouting are required, the drilling device 300 descends to drill and clean the holes. After milling and drilling are completed, the vehicle-mounted platform 100 moves away, the paving execution mechanism is unloaded from the loading platform, and repair material is injected into the repair area. After paving is completed, the vehicle-mounted platform 100 moves again to cover the repair area, the first skirt 101 descends to form an enclosing space, and the maintenance system provides constant temperature and humidity maintenance for the repair area. The entire single-point repair process is compact and interconnected, suitable for rapid and high-quality repair of localized defects in pavement slabs.

[0060] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
