Description

Technical Field

[0001] This utility model relates to the field of aircraft de-icing technology, specifically to a de-icing truck bucket for aircraft de-icing vehicles. Background Technology

[0002] An aircraft de-icing truck is a specially designed ground support vehicle. Its core function is to remove frost, ice, snow, and other contaminants from the aircraft surface by spraying specialized heated de-icing / anti-icing fluid in cold weather conditions, and to provide the aircraft with anti-icing protection for a certain period of time to ensure flight safety. The de-icing truck bed refers to the dedicated work compartment installed at the end of the aircraft de-icing truck's lifting arm, used to carry the operator and serve as a platform for spraying de-icing / anti-icing fluid.

[0003] Application No. 202322358919.5 discloses a de-icing truck bed for aircraft de-icing vehicles. This patent includes a truck bed body, a support block fixedly connected to the bottom side of the truck bed body, a grid contacting the upper side of the support block, and fixed rings uniformly fixedly connected to the upper side of the truck bed body. A connecting sleeve contacts the inner side of the fixed ring, and the connecting sleeve is integrally cast with a spring cloth. A circular groove is formed on the spring cloth. A water drainage groove is formed on the bottom side of the truck bed body. The spring cloth is located on the upper side of the truck bed body, and zippers are provided on both sides of the circular groove on the spring cloth. This utility model, by setting fixed rings and spring cloth inside the truck bed body, and installing a grid and water drainage groove on the bottom side of the truck bed body, and then using adjustable zippers and pull heads to accommodate operators of different body sizes for water spraying operations, reduces water entering the truck bed body. Furthermore, heating pipes and fans improve the comfort inside the truck bed body, reducing the impact of the operating environment on the operator.

[0004] While the above comparison documents can reduce the impact of the environment on operators, they do not have a buffer mechanism installed at the bottom of the de-icing truck bed, which can easily lead to a hard collision between the working bed and the ground. The impact load generated by long-term collisions can damage the bottom structure of the truck bed, thereby increasing the risk of accidents. Utility Model Content

[0005] The purpose of this utility model is to provide a de-icing truck bucket for aircraft de-icing vehicles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a de-icing truck bed for an aircraft de-icing vehicle, comprising a working cabin, a seat, and side windows. The working cabin is equipped with a seat, and side windows are embedded in both sides of the middle of the outer wall of the working cabin. A front door is rotatably connected to one side of the outer wall of the working cabin, and a rear door is rotatably connected to the other side of the outer wall of the working cabin. A scraper mechanism is connected to the outer wall of the front door for scraping away debris from the outer wall of the front door. Limiting plates are fixedly connected to both sides of the bottom center of the working cabin, and a lifting arm fixing base is connected to the outer side of the bottom of the working cabin. The limiting plates can extend into the lifting arm fixing base to restrict the working cabin and prevent it from moving horizontally. The bottom corner of the lifting arm fixed base is equipped with a fixed column, and a fixed rod is slidably connected inside the fixed column. A protective plate is welded to the bottom of the fixed rod, and a spring is sleeved in the middle of the fixed rod. The protective plate and the spring work together to absorb impact loads.

[0007] By transforming harsh, hard impacts into gentler cushioning, the bottom structure of the work cabin is fundamentally protected from long-term impact damage, thereby extending the equipment's lifespan.

[0008] Preferably, the lifting arm fixing base is a "U" shaped mechanism, the lifting arm fixing base has a limiting cavity corresponding to the limiting plate, the front door is made of transparent tempered glass, and a damper is installed in the middle of the bottom end of the protective plate.

[0009] Subsequently, a damper is used to prevent the spring from vibrating repeatedly and to avoid rebound.

[0010] Preferably, the protective plate has an "L" shaped structure, the top of the spring is fixedly connected to the bottom of the fixing post, and the fixing post, fixing rod, spring and protective plate form an elastic telescopic mechanism.

[0011] Springs absorb most of the impact energy through compression deformation.

[0012] Preferably, the limiting plate has limiting holes on both sides inside, and a reinforcing rod is connected inside the limiting hole. A threaded rod is welded to one side of the outer wall of the reinforcing rod, and the reinforcing rod and the limiting plate form a "U" shape.

[0013] The threaded locking mechanism, consisting of components such as threaded rods, bears the vertical tension and ensures that the whole structure does not loosen.

[0014] Preferably, a limiting seat is threadedly connected to the middle of the outer wall of the threaded rod, and a nut is threadedly connected to one side of the outer wall of the threaded rod. The top of the outer wall of the limiting seat is welded to the bottom of the lifting arm fixing base, and the cross-section of the reinforcing rod is a "T" shaped structure.

[0015] By passing the reinforcing rod through the limiting plate and bringing its threaded end close to the limiting seat; then, rotating the reinforcing rod so that the threaded end screws into and passes through the limiting seat; finally, tightening the nut to push it along the threaded end until it fits tightly against the outer wall of the limiting seat, the final fixation of the work cabin at the end of the lifting arm is completed.

[0016] As can be seen from the above, the de-icing truck bucket for aircraft de-icing vehicles provided by this utility model has the following beneficial effects.

[0017] The limiting plate and threaded locking mechanism complete the final fixation of the working cabin at the end of the lifting arm. The limiting plate bears the main horizontal force, while the threaded rod and other components bear the vertical tensile force and ensure that the whole structure does not loosen. This makes the connection stable and the force distribution reasonable. Furthermore, no special tools are required for disassembly and installation, which facilitates later inspection, maintenance or replacement.

[0018] By absorbing most of the impact energy through spring compression deformation, the working chamber is prevented from colliding hard with the ground, and the violent hard impact is transformed into a gentle buffer, fundamentally protecting the bottom structure of the working chamber from long-term impact damage, thereby extending the service life of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-12 This utility model provides a technical solution: a de-icing truck bed for an aircraft de-icing vehicle, including a working cabin 1, a seat 2 and side windows 3. The seat 2 is installed inside the working cabin 1, and the side windows 3 are embedded on both sides of the middle of the outer wall of the working cabin 1. A front door 4 is rotatably connected to one side of the outer wall of the working cabin 1, and a rear door 5 is rotatably connected to the other side of the outer wall of the working cabin 1. A scraper mechanism 6 is connected to the outer wall of the front door 4 for scraping away debris from the outer wall of the front door 4. Limiting plates 7 are fixedly connected to both sides of the bottom center of the working cabin 1, and a lifting arm fixing base 8 is connected to the outer side of the bottom of the working cabin 1. The limiting plates 7 can extend into the lifting arm fixing base 8 to restrict the working cabin 1 and prevent it from moving horizontally. Limiting holes are opened on both sides inside the limiting plates 7, and a reinforcing rod 13 is connected inside the limiting holes. A threaded rod 14 is welded to one side of the outer wall of the reinforcing rod 13, and the reinforcing rod 13 and the limiting plates 7 have a "U" shaped structure. A limiting seat 15 is threadedly connected to the middle of the outer wall of the threaded rod 14, and a nut 16 is threadedly connected to one side of the outer wall of the threaded rod 14. The top of the outer wall of the limiting seat 15 is welded to the bottom of the lifting arm fixing base 8, and the cross-section of the reinforcing rod 13 has a "T" shaped structure.

[0023] A fixed column 9 is installed at the bottom corner of the fixed base 8 of the lifting arm, and a fixed rod 10 is slidably connected inside the fixed column 9. A protective plate 12 is welded to the bottom of the fixed rod 10, and a spring 11 is sleeved in the middle of the fixed rod 10. The protective plate 12 works with the spring 11 to absorb impact loads. The protective plate 12 has an "L" shaped structure. The top of the spring 11 is fixedly connected to the bottom of the fixed column 9. The fixed column 9, the fixed rod 10, the spring 11 and the protective plate 12 form an elastic telescopic mechanism. The lifting arm fixing base 8 is a "U" shaped mechanism. The lifting arm fixing base 8 has a limiting cavity inside that corresponds to the limiting plate 7. The front door 4 is made of transparent tempered glass, and a damper is installed in the middle of the bottom end of the protective plate 12.

[0024] In practice, after receiving the de-icing task instruction and identifying the target aircraft and its location, the operator smoothly drives the de-icing truck to the side and front of the aircraft or the designated work area, ensuring a safe distance between the vehicle and the aircraft. Then, the vehicle's outriggers are lowered to ensure stability, and a static grounding wire is connected to prevent static electricity from igniting the de-icing fluid. Next, the operator in seat 2 operates the lifting controller to smoothly raise the truck bed to a height slightly below the pre-operation wing height. The operator slowly moves the vehicle, bringing the truck bed close to the leading edge of the aircraft wing. Inside the truck bed, the operator uses micro-motion controls to adjust the spray arms and nozzles to the optimal starting position and angle. At this time, the scraper mechanism 6 can move to scrape away debris from the outer wall of the front door 4, and the operator can observe the external situation of the work cabin 1 through the side window 3 and the front door 4. Then, heated de-icing fluid is used to impact the aircraft surface, melting and washing away the accumulated snow and ice. Subsequently, a layer of viscous anti-icing fluid is applied to the clean aircraft surface to prevent re-icing before takeoff, ensuring that the aircraft can take off safely and on time in extreme weather conditions.

[0025] See Figure 1 and Figure 2 The operator can choose to enter the working compartment 1 from the front door 4 or the rear door 5 according to the actual situation on site, which improves the flexibility of the de-icing truck bed. In case of emergency, if one of the front door 4 and the rear door 5 malfunctions and cannot be opened, the operator can quickly leave the working compartment 1 through the other door, thereby reducing the risk of accidents.

[0026] See Figure 4 , Figure 9 , Figure 11 and Figure 12 When fixing the working cabin 1 to the end of the lifting arm, first align the bottom of the working cabin 1 with the top of the lifting arm fixing base 8, so that the limiting plate 7 is embedded inside the lifting arm fixing base 8 to limit the horizontal displacement of the working cabin 1; then, pass the reinforcing rod 13 through the limiting plate 7, so that the threaded rod 14 at its front end is close to the limiting seat 15; next, rotate the reinforcing rod 13 so that the threaded rod 14 is screwed into and passes through the limiting seat 15; finally, tighten the nut 16 so that it is pushed along the threaded rod 14 until it is tightly fitted with the outer wall of the limiting seat 15, thus completing the final fixing of the working cabin 1 to the end of the lifting arm. Furthermore, the limiting plate 7 bears the main horizontal force, and the threaded locking mechanism composed of the threaded rod 14 and other components bears the vertical tensile force and ensures that the whole does not loosen, making the connection stable and the force reasonable. Moreover, no special tools are required for disassembly and installation, which facilitates later inspection, maintenance or replacement.

[0027] See Figure 4 , Figure 7 and Figure 10When the working chamber 1 finishes de-icing and moves to the ground, the protective plate 12 at the bottom of the lifting arm fixed base 8 will first contact the ground. The impact force drives the protective plate 12 to move upward, causing the fixed rod 10 to slide along the fixed column 9 and compressing the spring 11. The spring 11 absorbs most of the impact energy through compression deformation, and subsequently, a damper prevents the spring 11 from vibrating repeatedly and rebounding, thus preventing the working chamber 1 from having a hard collision with the ground. This coordinated working process transforms the violent hard collision into a gentle buffer, fundamentally protecting the bottom structure of the working chamber 1 from long-term impact damage, thereby extending the service life of the equipment.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
