Description

Technical Field

[0001] This utility model relates to the technical field of airport de-icing vehicles, specifically an airport de-icing vehicle that is easy to refill with de-icing fluid. Background Technology

[0002] An airport runway is an extra-long strip of land within an airport used for the take-off or landing of aircraft. It is usually made of asphalt or concrete. Airport runways are classified into different grades based on their length, width, and other characteristics.

[0003] During airport runway use, snow and ice accumulation can significantly reduce visibility, making it difficult for pilots to judge the runway's position and potentially causing aircraft to veer off course. Icing also reduces friction between the aircraft's landing gear and the runway, resulting in longer taxiing distances and making the aircraft's direction harder to control. This increases the risk of aircraft overrunning the runway, posing a danger to takeoffs and landings. Therefore, de-icing vehicles are necessary to clear ice and snow from the runways to ensure smooth takeoffs and landings.

[0004] When refilling de-icing fluid into a de-icing truck, the refill nozzle is aimed at the truck's refill port, and the de-icing fluid from the refill station is then delivered to the truck's storage tank via the nozzle. During the refilling process, there is usually no limit function for the refill nozzle; it is simply inserted directly into the refill port. If the nozzle is subjected to an accidental impact, it can easily detach from the refill port, causing de-icing fluid leakage and affecting the refilling effect. Furthermore, the impact between the nozzle and the refill port can easily cause deformation and damage to the refill port, affecting subsequent use. Utility Model Content

[0005] The purpose of this utility model is to provide an airport de-icing vehicle that facilitates de-icing fluid refilling, improves the stability of the connection between the refilling gun and the refilling port, and uses a positioning post to effectively limit the refilling gun, preventing collisions between the gun body and the refilling port and protecting the refilling port. This allows for smooth refilling operations and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an airport de-icing vehicle that facilitates de-icing fluid refill, comprising a storage tank and a frame connected to the bottom of the storage tank, wherein a filling port is provided on the side of the storage tank, and positioning posts are connected to both sides of the filling port. The positioning posts are matched with a snap-fit ​​plate, and the positioning posts are connected to a positioning mechanism for positioning the snap-fit ​​plate. The positioning mechanism includes two snap-fit ​​blocks, two rotating shafts, two torsion springs, and two limiting blocks. The snap-fit ​​blocks are rotatably connected to the positioning posts through the rotating shafts. The torsion springs are used to drive the snap-fit ​​blocks to rotate around the rotating shafts. The limiting blocks are used to limit the snap-fit ​​blocks, and the limiting blocks are connected to a driving mechanism for the two limiting blocks to rotate synchronously toward the interior of the positioning posts.

[0007] Preferably, one end of the torsion spring is connected to the positioning post, and the other end is connected to the rotating shaft.

[0008] Preferably, the positioning post is provided with a second guide hole for guiding the locking block.

[0009] Preferably, the snap-fit ​​block is slidably connected to the guide hole two, and the bottom of the snap-fit ​​block is connected to the limiting block, the width of the limiting block being greater than the width of the guide hole two.

[0010] Preferably, the driving mechanism includes four spheres, four push rods, a U-shaped plate, and two guide posts. The spheres are connected to the inclined grooves provided on the limiting block. The two ends of the push rods are connected to the spheres and the U-shaped plate. The guide posts are used to guide the U-shaped plate.

[0011] Preferably, the guide post is connected inside the positioning post, and the guide post matches the guide groove provided in the U-shaped plate.

[0012] Preferably, the positioning post is provided with a guide hole, and the U-shaped plate is slidably connected to the guide hole.

[0013] Preferably, the end of the positioning post has a rounded corner structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a positioning post, a positioning mechanism, and a driving mechanism, aligns the locking plate of the dispensing gun with the corresponding positioning post, moves the gun body towards the dispensing port, slides the connecting hole relative to the locking block, drives the locking block to rotate, and further coils the torsion spring until the gun body is inserted into the dispensing port. At this point, the connecting seat connects with the front end face of the dispensing port, and the coiled torsion spring releases its elasticity, causing the locking block to rotate. The straight end of the locking block connects with the front end of the locking plate, thus achieving good positioning of the dispensing gun and improving the stability of the connection between the dispensing gun and the dispensing port. At the same time, when the dispensing gun is subjected to accidental impact, the positioning post plays a good role in positioning the dispensing gun, preventing the gun body from colliding with the dispensing port, protecting the dispensing port, and allowing for smooth dispensing operations.

[0017] 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.

[0018] Please see Figures 1 to 3 This utility model provides an airport de-icing vehicle that facilitates de-icing fluid refilling. It includes a reservoir 1 and a frame connected to the bottom of the reservoir 1. A filling port 3 is provided on the side of the reservoir 1, and positioning posts 9 are connected to both sides of the filling port 3. The positioning posts 9 are matched with a snap-fit ​​plate 6. The positioning posts 9 are connected to a positioning mechanism for positioning the snap-fit ​​plate 6. The positioning mechanism includes two snap-fit ​​blocks 10, two rotating shafts 12, two torsion springs 13, and two limiting blocks 15. The snap-fit ​​blocks 10 are rotatably connected to the positioning posts 9 via the rotating shafts 12. The torsion springs 13 drive the snap-fit ​​blocks 10 to rotate around the rotating shafts 12. The limiting blocks 15 limit the snap-fit ​​blocks 10, and are connected to a drive mechanism for the two limiting blocks 15 to rotate synchronously towards the interior of the positioning posts 9.

[0019] The filling gun 2 includes a gun body 5, two snap-fit ​​plates 6, two connecting holes 7, and a connecting seat 8. A filling pipe 4 is connected to the end of the gun body 5. The filling pipe 4 is connected to the drain end of the filling station. De-icing fluid is transported from the filling station into the filling pipe 4, and then from the gun body 5 to the storage tank 1, achieving the filling purpose. Both ends of the connecting seat 8 are connected to the snap-fit ​​plates 6, and the connecting holes 7 are located on the snap-fit ​​plates 6 and match the positioning pins 9.

[0020] The inner surface of the connecting seat 8 is a, the front end face of the filling port 3 is b, the straight surface of the locking block 10 is c, and the front end face of the locking plate 6 is e, with e having a certain curvature. When a and b are connected, c and e are connected, which can effectively limit the filling gun 2 and improve the stability of the connection between the gun body 5 and the filling port 3.

[0021] During the docking process between the filling gun 2 and the filling port 3, the gun body 5 is pushed towards the filling port 3, and the positioning pin 9 is inserted into the connecting hole 7 of the snap-fit ​​plate 6. The snap-fit ​​plate 6 and the snap-fit ​​block 10 slide relative to each other, causing the snap-fit ​​block 10 to rotate around the rotating shaft 12. The torsion spring 13 is tightened until a and b are connected. The tightened torsion spring 13 releases its elasticity, driving the snap-fit ​​block 10 to rotate, connecting c and e, thereby limiting and fixing the filling gun 2. The operation is simple and convenient. When the filling gun 2 is accidentally impacted, the positioning pin 9 effectively limits the filling gun 2, preventing the gun body 5 from colliding with the filling port 3, protecting the filling port 3, and allowing the filling operation to proceed smoothly.

[0022] One end of the torsion spring 13 is connected to the positioning post 9, and the other end is connected to the rotating shaft 12.

[0023] The positioning post 9 is provided with a guide hole 19 for guiding the locking block 10. The locking block 10 is slidably connected to the guide hole 19, and the bottom of the locking block 10 is connected to the limiting block 15. The guide hole 19 ensures that the locking block 10 rotates stably and prevents it from tilting or shifting. The width of the limiting block 15 is greater than the width of the guide hole 19. Under normal conditions, the torsion spring 13 is also in a tightened state, driving the locking block 10 to rotate in the direction of rotation. Figure 3 The middle arrow points to the center. The limiting block 15 serves to limit the locking block 10, preventing the end of the locking block 10 from tilting up.

[0024] The drive mechanism includes four balls 14, four push rods 16, a U-shaped plate 11, and two guide posts 18. The balls 14 are connected to the inclined grooves of the limiting block 15. The two ends of the push rods 16 are connected to the balls 14 and the U-shaped plate 11. The guide posts 18 are used to guide the U-shaped plate 11. When the filling gun 2 needs to be removed, the U-shaped plate 11 is pushed forward, which drives the four push rods 16 to move forward synchronously, so that the balls 14 slide relative to the inclined grooves of the limiting block 15. This drives the locking block 10 to rotate closer to the positioning post 9. When the locking block 10 is fully inserted into the positioning post 9, the filling gun 2 is released. The filling gun 2 can then be pulled directly to separate the locking plate 6 from the positioning post 9. The operation is simple and flexible.

[0025] The guide post 18 is connected to the positioning post 9, and the guide post 18 matches the guide groove provided in the U-shaped plate 11.

[0026] The positioning post 9 is provided with a guide hole 17, and the U-shaped plate 11 is slidably connected to the guide hole 17. In conjunction with the use of the guide post 18, the stability of the movement of the U-shaped plate 11 is improved, that is, the four balls 14 move steadily.

[0027] The end of the positioning post 9 has a rounded corner structure, which facilitates the docking of the snap-fit ​​plate 6 with the positioning post 9, so that the positioning post 9 can be smoothly inserted into the connecting hole 7.

[0028] Working principle: The gun body 5 is inserted into the filling port 3, and the positioning pin 9 is inserted into the connecting hole 7 of the locking plate 6. The locking block 10 rotates around the rotating shaft 12, and the torsion spring 13 is further wound up until a and b are connected. At this time, the gun body 5 stops moving and is inserted into the filling port 3. The wound torsion spring 13 releases its elasticity, driving the locking block 10 back to its original position, so that c and e are connected, thereby limiting and fixing the filling gun 2 and improving the stability of the connection between the filling gun 2 and the filling port 3. When the filling gun 2 is accidentally impacted, the positioning pin 9 provides good limiting for the filling gun 2, preventing the gun body 5 from colliding with the filling port 3 and protecting the filling port 3, allowing the filling operation to proceed smoothly. After filling is completed, the U-shaped plate 11 is pushed forward, simultaneously driving the four push rods 16 and the four balls 14 to move forward, so that the balls 14 slide relative to the inclined groove of the limiting block 15, driving the four locking blocks 10 to rotate in the direction of rotation. Figure 3 Reverse the direction of the middle arrow until c is fully inside the positioning post 9 to loosen the locking plate 6, separate the gun body 5 from the filling port 3, and unload the filling gun 2. The operation is flexible and convenient.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
