Description

Technical Field

[0001] This utility model relates to the field of airport runway cleaning technology, and in particular to an airport runway cleaning vehicle. Background Technology

[0002] With the stable development of my country's economic system, people's living standards have continued to improve, and disposable income has also increased. my country's civil aviation reached 620 million passenger trips in 2023, a year-on-year increase of 146.1%. During the National Day holiday in 2024 alone, the daily passenger volume of civil aviation reached 2.3 million, which reflects higher requirements for the safety of the civil aviation system.

[0003] Aircraft runways are essential facilities for the takeoff and landing of civil aircraft, and they have a crucial impact on flight safety. Any runway-related problems can lead to serious flight safety accidents. When an aircraft lands, the rubber tires generate a great deal of heat upon contact with the runway. The high temperature causes the rubber tires to melt instantly, leaving rubber residue on the runway. As the number of aircraft taking off and landing increases, the rubber layer on the runway becomes thicker, and the friction coefficient between the aircraft and the runway decreases due to excessive snow accumulation caused by winter snowfall.

[0004] This solution proposes an airport runway cleaning vehicle to address the problems that pose a threat to flight safety and are difficult to remove, such as rubber residue left on the runway due to friction during aircraft takeoff and landing, and snow accumulation on the runway causing reduced takeoff and landing performance and increased taxiing distance. Utility Model Content

[0005] The main purpose of this utility model is to propose an airport runway cleaning vehicle, which aims to solve the problems that pose a threat to flight safety and are difficult to remove, such as rubber residue left on the runway due to friction during aircraft take-off and landing, snow accumulation on the runway causing reduced take-off and landing performance, increased taxiing distance, etc.

[0006] To achieve the above objectives, the airport runway cleaning vehicle proposed in this utility model includes:

[0007] The vehicle body has a first connecting module on one end corresponding to the driver's end, and the first connecting module has multiple jet nozzles;

[0009] The snow removal assembly includes a snow shovel assembly and a second connecting module. The second connecting module can form a fixed connection with the first connecting module to install the snow shovel assembly under the driver's side of the vehicle body.

[0010] In one embodiment, the vehicle body is equipped with a water storage tank;

[0011] The adhesive removal assembly also includes a rinsing assembly, which is installed on the vehicle body.

[0012] In one embodiment, the rinsing assembly includes:

[0013] A nozzle assembly is rotatably mounted on the bottom of the vehicle body along an axis extending vertically, and one end of the nozzle assembly is connected to the water storage tank; and,

[0014] The pressurization component is installed on the vehicle body and connected to the water storage tank.

[0015] In one embodiment, the flushing assembly further includes a rotary drive unit mounted on the bottom of the vehicle body and connected to the nozzle component for driving the nozzle component to rotate about an axis extending in the vertical direction.

[0016] In one embodiment, the vehicle body is equipped with a water storage tank;

[0018] A pump body, mounted on the vehicle body, and having a sludge collection pipe at its inlet end; and,

[0019] A collection box is mounted on the vehicle body on one side corresponding to the water storage tank, and the output end of the pump body is connected to the collection box.

[0020] In one embodiment, the collection tank is equipped with a filter element for filtering rubber debris from the wastewater.

[0021] In one embodiment, the airport runway cleaning vehicle is further provided with a finishing assembly, which includes a housing and a heating unit. The housing is located near the rear of the vehicle body and below the vehicle body.

[0023] In one embodiment, the bottom of the vehicle body is further provided with a mounting bracket, on which the cleaning roller is rotatably mounted. The bottom of the vehicle body is also provided with a vertical drive unit, the output end of which is connected to the mounting bracket to drive the mounting bracket to move in the vertical direction.

[0024] In one embodiment, the steam softening assembly includes:

[0025] A steam generator is installed at the driver's side of the vehicle body, and the output end of the steam generator is connected to a plurality of jet nozzles; and,

[0026] A pressurization device, connected to the steam generator, is used to force steam to be ejected from the jet nozzle.

[0027] The technical solution of this utility model breaks through the limitation of the single function of traditional cleaning vehicles. Through modular design, different cleaning accessories can be replaced by docking. The two modes of adhesive removal and snow removal can be switched at will in a very short time, and it can handle different cleaning problems with ease.

[0028] The automatic modular docking system, in conjunction with high-precision positioning sensors and adaptive suspension control, enables precise module docking and can complete the switching of cleaning modes in a very short time, greatly shortening the runway maintenance cycle.

[0029] Unlike traditional single-process cleaning vehicles, the multi-process cleaning device upgrades the cleaning process to three steps: initial treatment at the front end, powerful cleaning at the end, and final cleaning at the back. This ensures efficient running track cleaning while also allowing the track to be quickly put back into use. Attached Figure Description

[0042] With the stable development of my country's economic system, people's living standards have continued to improve, and disposable income has also increased. my country's civil aviation reached 620 million passenger trips in 2023, a year-on-year increase of 146.1%. During the National Day holiday in 2024 alone, the daily passenger volume of civil aviation reached 2.3 million, which reflects higher requirements for the safety of the civil aviation system.

[0043] Aircraft runways are essential facilities for the takeoff and landing of civil aircraft, and they have a crucial impact on flight safety. Any runway-related problems can lead to serious flight safety accidents. When an aircraft lands, the rubber tires generate a great deal of heat upon contact with the runway. The high temperature causes the rubber tires to melt instantly, leaving rubber residue on the runway. As the number of aircraft taking off and landing increases, the rubber layer on the runway becomes thicker, and the friction coefficient between the aircraft and the runway decreases due to excessive snow accumulation caused by winter snowfall.

[0044] This solution proposes an airport runway cleaning vehicle to address the problems that pose a threat to flight safety and are difficult to remove, such as rubber residue left on the runway due to friction during aircraft takeoff and landing, and snow accumulation on the runway causing reduced takeoff and landing performance and increased taxiing distance.

[0045] This utility model proposes an airport runway cleaning vehicle 100 to solve the above problems.

[0046] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5In one embodiment of this utility model, the airport runway cleaning vehicle 100 includes a vehicle body 1, an adhesive removal component 2, and a snow removal component 4. The vehicle body 1 has a first connecting module 13 at one end corresponding to its driver's side, and the first connecting module 13 has multiple air jets 131. The adhesive removal component 2 includes a steam softening component 21, which is mounted on the vehicle body 1, and its output end is connected to the multiple air jets. The snow removal component 4 includes a snow shovel component 41 and a second connecting module 42, which can be fixedly connected to the first connecting module 13 to install the snow shovel component 41 below the driver's side of the vehicle body 1.

[0047] The vehicle body 1 has a driving end and a rear end. In the following description, the direction of the driving end and the rear end of the vehicle body 1 is the front-to-back direction, and the up-down direction corresponds to the vertical direction. In this embodiment, the first connecting module 13 is specifically installed in the lower area of ​​the driving end of the vehicle body 1. The entire vehicle body 1 can switch between two cleaning modes through the setting of the first connecting module 13. Specifically, the two cleaning modes include a rubber removal mode and a first snow removal mode. When the entire vehicle body 1 is in the rubber removal mode, the steam softening component 21 located at the driving end of the vehicle body 1 starts to work. It can spray high-temperature and high-pressure steam outward through multiple jet nozzles 131 on the first connecting module 13, thereby softening the rubber on the track. The softened rubber is easier to clean than the original rubber, and the softened rubber can be cleaned by the corresponding cleaning structure. When the entire vehicle body 1 is in snow removal mode, the second connection module 42 and the first connection module 13 are connected, thereby installing the entire snow removal assembly 41 at the front of the driver's end of the vehicle body 1. During the entire movement of the vehicle body 1, snow removal operations can be completed simultaneously.

[0048] The first connecting module 13 and the second connecting module 42 can be configured for manual installation, such as by fixing them together with a threaded structure or by connecting them with a snap-fit ​​structure. In this embodiment, the first connecting module 13 has a corresponding snap-fit ​​protrusion structure, and the second connecting module 42 has a corresponding snap-fit ​​groove structure. After the two are mated, a corresponding driving component can drive a corresponding limiting structure to prevent the snap-fit ​​protrusion structure from coming out of the snap-fit ​​groove structure. Through the above-mentioned detachable fixing method, the corresponding cleaning mode can be selected to clean the runway according to different conditions.

[0049] It is conceivable that the aforementioned automatic modular docking system can be installed on the vehicle body 1 structure. The aforementioned automatic docking system can be equipped with a high-precision positioning sensor and adaptive suspension control, which can achieve precise module docking and complete the switching of cleaning mode in a very short time, greatly shortening the maintenance cycle of the runway.

[0050] In some embodiments, the vehicle body 1 is provided with a water storage tank 11; the rubber removal assembly 2 further includes a rinsing assembly 22, which is installed on the vehicle body 1, one end of which is connected to the water storage tank 11, and the output end of which is located below the water storage tank 11, so as to facilitate the separation of the softened rubber from the track.

[0051] To further enhance the automated rubber removal capability of the entire vehicle body 1 structure and allow the softened rubber to be better separated from the track, the aforementioned flushing assembly 22 is provided. The flushing assembly 22 is located behind the steam softening assembly 21. It can supply liquid through the water storage tank 11 and pressurize the water to generate a high-pressure water flow that impacts the track surface, causing the softened rubber to separate from the track surface.

[0052] Specifically, the flushing assembly 22 includes a nozzle 221 and a pressurizing component 222. The nozzle 221 is rotatably mounted on the bottom of the vehicle body 1 along an axis extending vertically, and one end of the nozzle 221 is connected to the water tank 11. The pressurizing component 222 is mounted on the vehicle body 1 and is connected to the water tank 11.

[0053] To further enhance the rinsing effect of high-pressure water, the nozzle component 221 is preferably configured as a dynamic nozzle structure. Specifically, the pressure booster 222 can increase the water pressure, and the nozzle component 221 can rotate around a vertical axis during water spraying, thereby further improving the cleaning effect of the nozzle.

[0054] In some embodiments, in order to facilitate the control of the rotation of the nozzle 221, the flushing assembly 22 further includes a rotation drive 223, which is mounted on the bottom of the vehicle body 1 and connected to the nozzle 221 to drive the nozzle 221 to rotate about an axis extending in the vertical direction.

[0055] When cleaning up softened rubber debris, the nozzle 221 can be rotated by the rotary drive unit 223. The rotary drive unit 223 can be configured as a motor structure, and the motor speed can be adjusted in real time according to the actual situation during actual rubber removal.

[0056] The specific structure is as follows: Figure 3As shown, in the relevant structure, the inlet pipe of the nozzle 221 is rotatably mounted on the vehicle body 1, and one end of it is rotatably connected to the outlet pipe of the water storage tank 11. Both are made of rigid metal pipes. The rotary drive unit 223 specifically includes a drive motor 44 mounted on the vehicle body 1. The output shaft of the drive motor 44 is provided with a first gear, which meshes with a second gear on the inlet pipe of the nozzle 221. During the operation of the drive motor 44, it synchronously drives the nozzle 221 to rotate, thereby achieving efficient dynamic rinsing. Furthermore, to ensure the stability of the two pipe structure rotation mounting points, a corresponding support frame is provided on the vehicle body 1 to reinforce the above-mentioned pipe structure.

[0057] It should be noted that the cleaning structures described above in this solution are all installed on the bottom structure of the vehicle body 1. Specifically, the snow-shoveling component 41 and the steam softening component 21 are also partially located below the driver's side of the vehicle body 1. Compared to traditional cleaning structures, this design eliminates the bulky and front-mounted design of traditional runway de-adhesive trucks' twisted-wire cleaning machines, resulting in a more compact overall system. Furthermore, the corresponding flushing components 22 are all located inside the vehicle body 1, preventing pipe aging and damage caused by external pipe leakage and maximizing the service life of the entire cleaning structure.

[0058] In some embodiments, such as Figure 1 and Figure 3 As shown above, a flushing assembly 22 is provided behind the steam softening assembly 21 to separate rubber debris from the track. For automatic collection of rubber debris, in this embodiment, the flushing assembly 22 further includes a wastewater collection assembly 224, which includes a pump body 2241 and a collection tank 2242. The pump body 2241 is mounted on the vehicle body 1, and its input end is provided with a sludge collection pipe; the collection tank 2242 is mounted on the vehicle body 1 on the side corresponding to the water storage tank 11, and the output end of the pump body 2241 is connected to the collection tank 2242.

[0059] Specifically, the input end of the pump body 2241 is installed below the vehicle body 1, corresponding to the rear position of the nozzle component 221. During operation, the pump body 2241 can draw water mixed with rubber debris into the collection tank 2242 for storage. After cleaning, the wastewater can be further treated to separate and collect the rubber debris, avoiding resource waste. Furthermore, the wastewater collection component 224 can simultaneously collect most of the water generated during the rinsing process, effectively ensuring the cleanliness of the runway surface after rinsing and preventing excessive wastewater residue.

[0060] To ensure effective wastewater collection, preferably, a cover shell 12 is provided at the bottom of the vehicle body 1, such as... Figure 3 As shown, the inlet pipes of both the nozzle 221 and the pump body 2241 are located inside the cover housing 12. The cover housing 12 effectively prevents wastewater splashing during rinsing and ensures the effective collection of waste liquid by the pump body 2241.

[0061] In some embodiments, a filter element (not shown) is provided in the collection box 2242 for filtering rubber debris in the wastewater.

[0062] The filter element is located near the opening of the collection box 2242. When wastewater is introduced into the collection box 2242, it will first be filtered through the filter element. Rubber debris in the wastewater will remain on the top of the filter element, and the filtered debris can be collected in a concentrated manner.

[0063] In some embodiments, the airport runway cleaning vehicle 100 is further provided with a finishing assembly 3, which includes a housing part 33 and a heating part 32. The housing part 33 is located below the vehicle body 1 near the rear of the vehicle body 1 and has a downward opening end 31. The heating part 32 is located inside the housing part 33 for heating and drying the runway.

[0064] The finishing component 3 is installed at the bottom of the vehicle body 1 corresponding to the parking space position. The finishing component 3 is mainly used for drying the runway surface. In the specific operation, the excess wastewater on the runway surface has been collected and treated by the wastewater collection component 224. There will still be some water stains on the runway surface. In order to ensure the dryness of the runway surface, the heating part 32 can be turned on at the same time to heat the runway surface while cleaning the runway. In order to ensure the heating effect, the installation height of the housing part 33 can be appropriately reduced, thereby ensuring the heating and drying effect of the heating part 32.

[0065] In another embodiment, the finishing assembly 3 can be configured for snow removal. As described above, during snow removal, the snow-shoveling assembly 41 at the front of the vehicle body 1 removes snow from the track. A salt-spreading device or a salt-spraying device can be installed on the housing 33. During the snow removal process of the entire vehicle body 1, the salt-spreading structure on the housing 33 can spread a thin layer of salt on the track, thereby clearing any remaining snow.

[0066] In some embodiments, such as Figure 1 , Figure 4 and Figure 5As shown, the snow removal assembly 4 also includes a cleaning roller brush 43, which is rotatably mounted on the bottom of the vehicle body 1 corresponding to one side of the snow removal assembly 41.

[0067] Specifically, the cleaning roller brush 43 is installed behind the snow removal assembly 41. As mentioned above, after the snow removal assembly 41 has cleared most of the snow on the track, the cleaning roller brush 43 can simultaneously contact the track surface to clean the remaining snow on the track surface.

[0068] In some embodiments, such as Figure 3 As shown, in order to further ensure the snow removal effect, a mounting bracket 14 is provided at the bottom of the vehicle body 1. The cleaning roller brush 43 is rotatably mounted on the mounting bracket 14. A vertical drive unit 15 is also provided at the bottom of the vehicle body 1. The output end of the vertical drive unit 15 is connected to the mounting bracket 14 to drive the mounting bracket 14 to move in the vertical direction.

[0069] When in the degreasing state, the vertical drive unit 15 drives the mounting frame 14 upward, separating the cleaning roller brush 43 from the track surface. When in the snow removal state, the vertical drive unit 15 drives the mounting frame 14 downward, bringing the cleaning roller brush 43 into contact with the track surface. The mounting frame 14 is also equipped with a corresponding drive device connected to the cleaning roller brush 43, which drives the cleaning roller brush 43 to rotate, thereby improving the cleaning effect on the track.

[0070] In some embodiments, such as Figure 1 , Figure 4 As shown, the steam softening assembly 21 includes a steam generator 211 and a pressurizing device 212. The steam generator 211 is installed at the driver's side of the vehicle body 1, and its output end is connected to a plurality of jet nozzles. The pressurizing device 212 is connected to the steam generator 211 to facilitate the ejection of steam from the jet nozzles.

[0071] During operation, the steam generator 211 produces a large amount of steam. Steam can be generated by heating water, either electrically or by gas. During continuous steam generation, the pressurization device 212 pressurizes the steam generator 211, thereby promoting the ejection of hot steam from the nozzle and softening the rubber on the runway.

[0072] Furthermore, regarding the overall exterior structure, for aesthetic reasons, the entire body can be designed with a streamlined shape, blending the overall style with that of an aircraft. Numerous luminous areas surround the vehicle, including power indicators, warning light strips, and lighting sources. The exterior utilizes high-strength, corrosion-resistant stainless steel and aluminum alloy materials to ensure the vehicle's durability and stability in harsh weather conditions. The interior uses high-temperature resistant and corrosion-resistant stainless steel. The vehicle surface has undergone rust-proofing treatment to improve its weather resistance.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
