Description

Technical Field

[0001] This invention relates to a rubber cleaning device, and more particularly, to a rubber cleaning device and method for airport runways. Background Technology

[0002] During aircraft takeoff and landing, the intense friction between the tires and the airport runway generates rubber debris that adheres to the runway surface. This debris reduces the runway's anti-skid performance, potentially leading to skidding during takeoff and landing, especially in rainy or snowy weather, seriously threatening flight safety. Therefore, regular rubber cleaning of airport runways is necessary. Existing technologies primarily employ two common methods for airport runway rubber cleaning: one uses a cleaning brush, driven by a high-speed rotating brush that uses friction between the bristles and the runway surface to wipe away the attached rubber debris; the other uses high-pressure flushing, where a high-pressure water pump pressurizes water and sprays it onto the runway surface, using the impact of the water flow to peel the rubber debris off. Additionally, some methods combine cleaning brushes with flushing, but the overall operational logic still revolves around brushing and simple rinsing, lacking a systematic cleaning and recovery process. However, these existing technologies have significant drawbacks; when using a cleaning brush, the bristles' hardness and friction are limited, making it difficult to completely remove firmly attached rubber debris, resulting in low cleaning efficiency. The cleaning results are unsatisfactory, and the bristles wear down easily after prolonged use, requiring frequent replacement and increasing maintenance costs. While the simple high-pressure washing method can remove some rubber debris, the wastewater containing debris generated during washing cannot be recovered in time, resulting in a significant waste of water resources and causing wastewater to overflow on the runway surface, affecting subsequent cleaning operations. At the same time, the rubber debris and wastewater are mixed together, making effective separation difficult, requiring additional manpower and resources for wastewater and debris treatment, resulting in low overall cleaning efficiency. In addition, some combined cleaning equipment lacks a stable operating structure, making it prone to shaking during cleaning, affecting cleaning accuracy. Furthermore, the lack of targeted solid-liquid separation and backwashing structures leads to easy clogging of filter components, further reducing the continuity and stability of cleaning operations.

[0003] Therefore, those skilled in the art are dedicated to providing a rubber cleaning device and method for airport runways that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0013] Furthermore, each of the three cleaning water pipes is provided with a reinforcing plate at its upper end. The upper inner side of each reinforcing plate is connected to the drive pipe sleeve through a reinforcing member. The drive pipe sleeve is fitted onto the main pipe and is used to drive the main pipe to rotate. The rotating power mechanism includes a driven wheel, which is fitted onto the upper half of the drive pipe sleeve. The driven wheel is connected to the driving wheel through a transmission belt. The driving wheel is connected to the output end of the drive motor, and the drive motor is mounted on the extraction mechanism.

[0014] The outer sides of each of the reinforcing plates and each of the cleaning water pipes are connected to the mounting block. A stabilizing wheel mounting bracket is provided on the outer side of the mounting block, and a stabilizing wheel is provided on the stabilizing wheel mounting bracket. The stabilizing wheel is used in conjunction with the extraction mechanism.

[0015] Furthermore, the extraction mechanism includes an annular extraction base. The inner sides of the supporting feet and the arc-shaped reinforcing member are connected to the outer wall of the annular extraction base. Each of the stabilizing wheels fits and cooperates with the inner wall of the annular extraction base. The lower end of the annular extraction base is flush with the lower end of the arc-shaped reinforcing member. The lower end of the annular extraction base has several first extraction ports penetrating the annular extraction base. The upper end of each first extraction port is connected to the extraction seat through an extraction cover. The extraction seat is disposed on the top seat. A vacuum pump is disposed on the extraction seat. The air inlet of the vacuum pump is connected to the extraction ring body, and the air outlet extends to the outside of the cleaning vehicle through a pipe and is equipped with an anti-backflow valve. The rated vacuum degree of the vacuum pump is not lower than -0.08MPa, which is used to provide continuous negative pressure suction for the extraction mechanism.

[0017] The lower end of the extraction cover is shaped to fit the second extraction port and the expanded extraction cavity, and the upper end of the extraction cover is simultaneously connected to the extraction ring body.

[0018] The extraction disc is provided with a central base, the middle section of the drive tube sleeve is rotatably inserted through the central base, the drive motor is provided on the extraction disc, and the output shaft of the drive motor is rotatably connected to the extraction ring.

[0019] Furthermore, the cleaning vehicle includes a cab and a cargo box;

[0020] The connecting assembly is connected to the front of the vehicle via the fixing seat; the cleaning water tank is installed inside the vehicle compartment and is located in the front half of the vehicle compartment;

[0021] The cleaning water tank has a recovery pipe above it, which is connected to the extraction hose. A solid-liquid discharge head is installed on the recovery pipe, and a solid-liquid filter plate is installed below the discharge head. The filter plate is inclined, with the front higher than the back, and is detachably mounted on a solid-liquid support frame. The support frame is mounted on a liquid recovery tank with its opening facing upwards. A solid recovery tank is located below the filter plate. The liquid recovery tank is equipped with a level sensor and a drain valve. The level sensor monitors the liquid level in the tank in real time, triggering an alarm when the level reaches 80% of the tank's volume. The drain valve is located at the bottom of the liquid recovery tank for discharging or recycling the recovered water.

[0022] Furthermore, the solid-liquid support frame has several rotatable backflush pipes, each of which is connected to the liquid recovery tank via a pipeline. Each backflush pipe is equipped with several backflush heads, each of which is used to flush the solids adhering to the solid-liquid filter plate. Each backflush pipe has a sprocket on its outer side, and each sprocket is connected by a chain. A backflush motor is used to drive the sprockets to move forward and backward, thereby controlling the flushing direction of the backflush heads.

[0023] The solid recycling bin has a recycling port at the top, and a guide plate installed inside the bin below the recycling port. A partition plate with filter holes is located in the middle section of the bin. The guide plate serves as a liquid collection chamber for collecting backwash water and unfiltered residual water. An openable, sealed door is located on one side of the bin, hinged to the bin and locked in place by a door lock. Anti-slip pads are provided at the bottom of the bin to facilitate the centralized cleaning and transportation of solid debris.

[0024] A method for cleaning rubber on airport runways involves a cleaning vehicle fixed to a supporting walking assembly via a connecting component. This allows the walking wheels at the bottom of the supporting legs to move along the runway, enabling the entire device to move. Arc-shaped reinforcing members between adjacent supporting legs enhance structural stability and reduce weight through weight-reduction ports. Simultaneously, stabilizing wheels on the outer side of the cleaning water pipes roll against the inner wall of the annular extraction base, ensuring smooth operation. During movement, the drive motor starts, rotating the driving wheel. Power is transmitted via a transmission belt to the driven wheel, causing the drive sleeve to synchronously rotate the main pipe and three cleaning water pipes. The high-pressure water pump in the cleaning water tank inside the cleaning vehicle pressurizes the water, which is then delivered to the main pipeline via extension pipes and connecting hoses. From there, the water is distributed to individual cleaning pipes. The water flow is sprayed out through cleaning nozzles located at the lower end of a rotatable ball inside the positioning tube. The nozzle's spray orifice diameter is 0.8-1.2mm, and the spray angle is adjustable from 30° to 60°, with an overlap rate of ≥20% between adjacent nozzle spray areas to ensure no cleaning blind spots. The high-pressure water flow thoroughly removes rubber debris from the track surface. Screwing in the clamping head secures the adjusted spray angle of the ball. Simultaneously, the vacuum pump on the extraction seat starts generating... Under continuous negative pressure, the first extraction port of the annular extraction base, the second extraction port of the extraction disc, and the extended extraction chamber work together to quickly suck in the rinsed wastewater and rubber debris. The mixture is then transported through the extraction hood, extraction ring, extraction hose, and recovery pipe to the solid-liquid discharge head of the cleaning vehicle. The mixture is discharged through the solid-liquid discharge head to a solid-liquid filter plate that is tilted (higher at the front, lower at the back). Solid rubber debris is trapped and slides down the filter plate to the solid recovery tank below, while liquid flows into the liquid recovery tank. A liquid level sensor on the liquid recovery tank monitors the liquid level in real time, triggering a trip button when the liquid level reaches 80% of the tank's volume. An alarm is triggered, and the recycled water can be discharged or recycled through the bottom drain valve. If there are many deposits on the solid-liquid filter plate that affect the filtration effect, the backwash motor drives the sprocket and chain to rotate the backwash pipe in both directions. The backwash pipe is connected to the liquid recovery tank through a pipeline, and the backwash head on its surface sprays water to wash away the deposits on the filter plate. The backwash water and the unfiltered residual water flow into the liquid collection chamber through the guide plate. The solid recovery tank can be used to collect and transport debris through a sealed door that can be opened on one side, completing the cleaning, recycling and solid-liquid separation of rubber debris from the entire airport runway.

[0025] The present invention has the following beneficial effects:

[0026] 1. This invention employs high-pressure flushing technology (high-pressure water pump rated working pressure ≥15MPa, cleaning nozzle spray orifice diameter 0.8-1.2mm, angle adjustable from 30° to 60°, overlap rate of adjacent nozzle spray areas ≥20%). It uses the impact force of high-pressure water flow to thoroughly peel off firmly attached rubber debris, achieving a cleaning effect far exceeding the friction effect of a cleaning brush. At the same time, it does not rely on brush bristles, avoiding the problem of frequent replacement due to brush bristle wear and reducing maintenance costs.

[0027] 2. This invention utilizes a ring-shaped extraction mechanism (a vacuum pump with a rated vacuum of ≥-0.08MPa, a first extraction port on the ring-shaped extraction base, a second extraction port on the extraction disc, and an extended extraction chamber) to recycle wastewater containing debris after rinsing in real time, avoiding water waste and runway surface overflow. Combined with the solid-liquid separation structure of the cleaning vehicle (a solid-liquid filter plate with a higher front and lower rear, and separate liquid and solid recovery tanks), it can quickly separate rubber debris from water without requiring additional manpower or resources, thus improving overall cleaning efficiency.

[0028] 3. In this invention, the supporting walking component enhances structural stability through an arc-shaped reinforcing member (with a weight-reducing port). The stabilizing wheel on the outside of the cleaning water pipe rolls against the inner wall of the annular extraction base, ensuring smooth operation and preventing shaking during cleaning from affecting accuracy. A backflushing cleaning structure (backflushing pipe, backflushing head, and a sprocket and chain driven by a backflushing motor) is set up to automatically flush the deposits on the solid-liquid filter plate, preventing the filter components from clogging and ensuring the continuity and stability of the cleaning operation. In addition, the liquid recovery tank in this invention is equipped with a liquid level sensor and a drain valve, which alarms when the liquid level reaches 80%. The recovered water can be discharged or recycled, further saving water resources. The solid recovery tank adopts an openable sealing door and anti-slip pads, and rubber debris is collected for easy transportation and cleaning, making operation convenient. The supporting walking component is connected to the cleaning vehicle through a detachable connecting component, and the cleaning nozzle angle can be adjusted by a ball and a clamping head, making the equipment highly flexible and adaptable to different track cleaning needs.

[0079] A method for cleaning rubber on airport runways involves a cleaning vehicle 3 fixed to a connecting seat 10 of a supporting walking assembly 1 via a connecting component 11. This drives the walking wheels 13 at the lower end of the supporting legs 12 to move along the airport runway, enabling the entire device to move. The arc-shaped reinforcing member 15 between adjacent supporting legs 12 enhances structural stability and reduces weight through the weight reduction port 16. Simultaneously, the stabilizing wheel 55 on the outside of the cleaning water pipe 27 rolls against the inner wall of the annular extraction base 56, ensuring smooth operation. During the movement of the device, the drive motor 51 starts, driving the drive wheel 50 to rotate. The power is transmitted to the driven wheel 38 via the transmission belt 39, causing the drive sleeve 37 to drive the main pipe 32 and the three cleaning water pipes 27 synchronously. The high-pressure water pump in the cleaning water tank 5 inside the cleaning vehicle 69, with a rated working pressure ≥15MPa, pressurizes the water and delivers it to the main pipe 32 via the extension pipe 34 and connecting hose 33. The water is then distributed to each cleaning water pipe 27. The water flow is sprayed out through the cleaning nozzle 31 at the lower end of the rotatable ball 29 inside the positioning pipe 28. The nozzle spray orifice diameter is 0.8-1.2mm, the spray angle is adjustable from 30° to 60°, and the overlap rate of adjacent nozzle spray areas is ≥20%, ensuring no cleaning blind spots. The high-pressure water flow completely removes rubber debris from the runway surface. Screwing in the clamping head 30 fixes the adjusted spray angle of the ball 29. Simultaneously, the vacuum pump on the extraction seat 59... When the vacuum degree is ≥-0.08MPa, a continuous negative pressure is generated upon startup. The first extraction port 57 of the annular extraction base 56, the second extraction port 62 of the extraction disc 61, and the extended extraction chamber 63 work together to quickly suck in the flushed wastewater and rubber debris. This mixture is then transported through the extraction hood 58, extraction ring 65, extraction hose 60, and recovery pipe 71 to the solid-liquid discharge head 72 of the cleaning vehicle. The mixture is discharged through the solid-liquid discharge head 72 to the solid-liquid filter plate 73, which is inclined (higher at the front and lower at the back). Solid rubber debris is trapped and slides down the filter plate to the solid recovery tank 77 below, while liquid flows into the liquid recovery tank 76. A liquid level sensor on the liquid recovery tank 76 monitors the liquid level in real time. An alarm is triggered when the liquid level reaches 80% of the tank volume. The recovered water can be discharged or recycled through the bottom drain valve. If there are too many deposits on the solid-liquid filter plate 73, affecting the filtration effect, the backwash motor 82 drives the sprocket 80 and chain 81 to rotate the backwash pipe 78 in both directions. The backwash pipe 78 is connected to the liquid recovery tank 76 through a pipeline. The backwash head 79 on its surface sprays water to wash away the deposits on the filter plate. The backwash water and the unfiltered residual water flow into the liquid collection chamber 89 through the guide plate 86. The solid recovery tank 77 can be used for centralized cleaning and transportation of debris through a sealable door that can be opened on one side, completing the cleaning, recycling and solid-liquid separation of rubber debris from the entire airport runway.
