Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, and in particular to a prefabricated fifth-lane emergency take-off and landing device for elevated roads. Background Technology

[0002] With the rapid development of the low-altitude economy, aircraft are increasingly used in urban airspace, including in scenarios such as logistics distribution, emergency rescue, and passenger transportation. As an important infrastructure for the low-altitude economy, the demand for vertical take-off and landing facilities is becoming increasingly urgent.

[0003] In existing technologies, the take-off and landing facilities for low-altitude aircraft are mostly independent structures or rely on building rooftops or transportation hubs. These facilities suffer from long construction periods and difficulty in quickly responding to emergency needs. For elevated roads, emergency lanes are important emergency resources in urban traffic networks. If traditional take-off and landing facilities directly occupy emergency lanes, their emergency passage function will be affected in the long term. Therefore, there is an urgent need to develop a prefabricated fifth-lane emergency take-off and landing device that can not occupy emergency lane space or affect its original emergency function when not in use, and can be quickly assembled and deployed when needed to meet the safe take-off and landing requirements of low-altitude aircraft. This device would resolve the compatibility contradiction between emergency lanes on elevated roads and the take-off and landing needs of low-altitude aircraft. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a prefabricated fifth-lane emergency take-off and landing device for elevated roads.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a prefabricated fifth-lane emergency take-off and landing device for elevated roads, comprising: an elevated side baffle;

[0006] The support plate is rotatably connected to the elevated side baffle via a drive mechanism;

[0007] The buffer plate is fixedly connected to the upper surface of the support plate to withstand the impact of the aircraft.

[0008] The drive mechanism is used to drive the support plate to switch between being perpendicular to the road surface and parallel to the road surface.

[0009] The drive mechanism includes a drive motor, a first connecting rod, a second connecting rod, and a Z-shaped push rod. The first connecting rod is fixedly connected to the rotor of the drive motor, and the axis of the first connecting rod intersects the axis of the rotor of the drive motor. The second connecting rod is rotatably connected to the end of the first connecting rod away from the drive motor. The push rod is rotatably connected to the second connecting rod. The support plate is fixedly connected to the other end of the push rod. A Y-shaped groove is provided on the elevated side baffle. The connection point between the push rod and the support plate is slidably connected in the groove until one end of the groove bifurcation section. Under the drive of the first connecting rod, the connection point between the push rod and the second connecting rod slides from the intersection of the groove to the other end of the groove bifurcation section, and the push rod rotates 90 degrees.

[0010] In a preferred embodiment of this utility model, the cross-sectional shape of the slide groove is set as a constricted groove, the second connecting rod and the push rod are rotatably connected by a pin, the pin is slidably connected in the slide groove, and a rotating block is provided at the connection between the push rod and the support plate. The rotating block is slidably connected in the slide groove and rotates in the slide groove.

[0011] In a preferred embodiment of this utility model, a storage groove is provided on the side of the elevated side baffle that is close to the road surface. The horizontal height of the inner bottom surface of the storage groove is lower than the horizontal height of the road surface, and the groove edge away from the road surface is chamfered.

[0012] In a preferred embodiment of this utility model, the height of the storage groove is greater than the height of the support plate, and a rotating groove communicating with the storage groove is provided on the elevated side baffle, the rotating groove providing rotation space for the support plate to rotate.

[0013] In a preferred embodiment of this utility model, the height of the storage groove is equal to the sum of the height of the support plate and the height of the support plate when it is stored in the storage groove.

[0014] In a preferred embodiment of this utility model, the length of the straight section of the slide is equal to the stroke required to lift the short arm end of the push rod when the support plate is fully retracted. One part of the bifurcated section of the slide coincides with the axis of the straight section, and the other part extends to one side. The lengths of the two ends of the bifurcated section of the slide are equal to the length of the push rod located in the slide.

[0015] In a preferred embodiment of this utility model, the first connecting rod, the second connecting rod, and the push rod are all rigid straight rods.

[0016] In a preferred embodiment of this utility model, the buffer plate is made of three layers of composite material: a surface layer, a middle layer, and a bottom layer. The surface layer is a high-friction coefficient rubber layer, the middle layer is a honeycomb aluminum core structure, and the bottom layer is a high-strength carbon fiber plate.

[0017] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0018] (1) In non-emergency situations, the support plate is vertically stored in the storage slot of the elevated side baffle, without occupying the effective passage width and clearance of the emergency lane, thus fully ensuring the normal passage function of the emergency lane. When the emergency take-off and landing function needs to be activated, the drive motor receives the command and starts, and the support plate slides upward and rotates to be laid on the road surface under the action of the drive mechanism, thus completing the laying process of the support plate and facilitating the start and stop of the aircraft.

[0019] (2) Through the planar linkage mechanism formed by the drive motor, connecting rod one, connecting rod two and the "Z" shaped push rod, and in conjunction with the high-precision "Y" shaped guide slide, the rotational motion of the drive motor is converted into a composite motion of "first vertical lifting and then horizontal flipping" of the support plate. The push rod moves along the straight section of the slide, vertically lifting the support plate out of the storage slot. When it moves to the bifurcation point of the slide, the mechanism constraint forces the push rod to flip 90 degrees, thereby accurately pushing the support plate to the horizontal position and locking it, ensuring the load-bearing rigidity and safety of the lifting platform.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figures 1-4As shown, a prefabricated fifth-lane emergency take-off and landing device for aircraft used on elevated roads includes: an elevated side panel 1 fixedly installed on the outside of the crash barrier of the elevated bridge by pre-embedded parts or anchor bolts; a support plate 2 made of rectangular high-strength alloy steel plate or composite material plate to ensure that it has sufficient bending stiffness and load-bearing capacity to support the weight of the aircraft, and is rotatably connected to the elevated side panel 1 by a drive mechanism; a storage groove 8 is provided on the side of the elevated side panel 1 closest to the road surface. When the aircraft does not need to be started or stopped, the support plate 2 is stored in the storage groove 8, which does not occupy road space. When an aircraft is parked, the support plate 2 is rotated out and laid on the road surface by the drive mechanism to ensure that the parking process of the aircraft is carried out smoothly and improve the utilization rate of the road surface.

[0028] The buffer plate 3 is fixedly connected to the upper surface of the support plate 2 to withstand the impact of the aircraft. The buffer plate 3 is made of three layers of composite material: a surface layer, a middle layer, and a bottom layer. The surface layer is a high-friction coefficient rubber layer, the middle layer is a honeycomb aluminum core structure, and the bottom layer is a high-strength carbon fiber plate. The rubber layer has a high friction coefficient, which can provide sufficient grip for the aircraft landing gear in rain and snow weather to prevent sideslip. The middle layer is a closed-cell aluminum alloy honeycomb core or a high-performance polymer foam core to absorb energy and buffer, effectively dispersing and absorbing the concentrated impact load at the moment of landing, and significantly reducing the dynamic load transmitted to the support structure and bridge. The bottom layer is a carbon fiber reinforced composite material plate or a high-strength steel plate to provide the final structural support stiffness, and evenly transmits the dispersed load to the support plate 2 below, forming a safe and reliable landing interface.

[0029] The drive mechanism is used to drive the support plate 2 to switch between perpendicular and parallel to the road surface. The drive mechanism includes a drive motor 41, a first connecting rod 42, a second connecting rod 43, and a Z-shaped push rod 44. The first connecting rod 42, the second connecting rod 43, and the push rod 44 are all rigid straight rods. The first connecting rod 42 is fixedly connected to the rotor of the drive motor 41, and its axis intersects with the rotor axis of the drive motor 41. The second connecting rod 43 rotates with the end of the first connecting rod 42 furthest from the drive motor 41. The push rod 44 is rotatably connected to the connecting rod 43. The support plate 2 is fixedly connected to the other end of the push rod 44. A Y-shaped groove 5 is provided on the elevated side baffle 1. The connection point between the push rod 44 and the support plate 2 is slidably connected in the groove 5 until one end of the bifurcation section of the groove 5. Under the drive of the connecting rod 42, the connection point between the push rod 44 and the connecting rod 43 slides from the intersection of the groove 5 to the other end of the bifurcation section of the groove 5, and the push rod 44 is rotated 90 degrees.

[0030] The drive motor 41 is a waterproof and dustproof servo motor or a high-torque stepper motor with a precision planetary reducer. The drive motor 41 is preferably a dual-head motor, which can drive two support plates 2 to rotate at the same time. Without considering cost, the single motor control has higher precision. The drive motor 41 is vertically fixed on the back of the elevated side baffle 1 or on the internal reinforcement structure. Its rotor is fixed to one end of the connecting rod 42 by a key connection. The start and stop of the drive motor 41 is intelligently controlled by the control center to ensure the standardization of the usage time and frequency of the entire drive motor 41.

[0031] Both connecting rod 42 and connecting rod 43 are preferably made of high-strength structural aluminum alloy, which has high strength. The push rod 44 is preferably made of high-strength alloy steel to ensure its structural integrity under complex stress conditions. The push rod 44 includes a long arm, an intermediate arm and a short arm. The intermediate arm connects the long arm and the short arm. The long arm is fixed to the support plate 2 by bolts or welding to increase the contact area and improve the stability of the support plate 2 when it is flipped.

[0032] The cross-sectional shape of the slide groove 5 is set as a constricted groove. The constricted groove makes it difficult for the pin 6 and the rotating block 7 sliding in the slide groove 5 to come out. The connecting rod 43 and the push rod 44 are rotatably connected by the pin 6. The pin 6 is slidably connected in the slide groove 5. The connection between the push rod 44 and the support plate 2 is provided with a rotating block 7. The rotating block 7 is slidably connected in the slide groove 5 and rotates in the slide groove 5. The cross-sectional shape of the pin 6 and the rotating block 7 is "I". The middle section of the pin 6 and the rotating block 7 is set as a cylinder, which makes the whole smoother and smoother when sliding, and also has the effect of giving way, ensuring the smooth operation of the entire driving process.

[0033] The inner bottom surface of the storage groove 8 is lower than the road surface level. The edge of the storage groove 8 away from the road surface is chamfered. The height of the storage groove 8 is greater than the height of the support plate 2. A rotating groove 9 connected to the storage groove 8 is provided on the elevated side baffle 1. The rotating groove 9 provides rotation space for the support plate 2 to rotate. The height of the storage groove 8 is equal to the sum of the height of the support plate 2 and the height of the support plate 2 when it is stored in the storage groove 8. After the support plate 2 is fully stored in the storage groove 8, it will drop a certain distance. At this time, the side wall of the road surface can abut against the support plate 2. The support plate 2 is safer when stored in the storage groove 8. The support plate 2 slides upward and then flips over. Some buffer rubber pads are adhered to the lower surface of the support plate 2. The rotation of the support plate 2 and its contact with the road surface reduce the impact on the road surface and improve the service life of the support plate 2 and the road surface.

[0034] The length of the straight section of the slide 5 is equal to the stroke required to lift the short arm end of the push rod 44 when the support plate 2 is fully retracted. One part of the bifurcated section of the slide 5 coincides with the axis of the straight section, and the other part extends to one side. The bifurcated section of the slide 5 is formed by the convergence of a first branch section and a second branch section at the intersection. The first branch section is the natural extension of the straight section. The axes of the two coincide and together constitute the main vertical path of the slide. The second branch extends from the intersection in a horizontal or slightly upward direction. The included angle of the bifurcation of the chute 5 is an acute angle, ensuring that starting from the intersection, the pin 6 can only move towards the second branch 53, while the rotating block 7 can only stay near the intersection and act as a fulcrum for rotation. This ensures the uniqueness and repeatability of the motion sequence and avoids the risk of jamming or uncertain motion path. The length of the two ends of the bifurcation of the chute 5 is equal to the length of the push rod 44 located in the chute 5, and the ends of the two bifurcations of the chute 5 are on the same plane. The length of the middle section of the push rod 44 is equal to the thickness of the support plate 2. After the support plate 2 is in contact with the road surface, the overall flatness is better.

[0035] Working principle:

[0036] When the support plate 2 is in the retracted state, the lower surface of the support plate 2 is in contact with the side wall of the road surface, which does not interfere with the width of the emergency lane or the driver's field of vision. The drive motor 41 is in the initial zero position. When the control system receives the unfolding command, the drive motor 41 starts to rotate. Through the planar linkage mechanism composed of the first linkage 42 and the second linkage 43, the rotational motion of the motor is converted into the linear motion of the pin 6 in the straight section of the "Y"-shaped slide groove 5.

[0037] The drive motor 41 starts and drives the first connecting rod 42 to rotate. The other part of the first connecting rod 42, the second connecting rod 43, applies an upward thrust. At the same time, the second connecting rod 43 pushes the push rod 44 to move upward. When the connection point between the push rod 44 and the support plate 2 slides to one end of the bifurcation section of the chute 5, the connection point between the push rod 44 and the second connecting rod 43 is located at the bifurcation of the chute 5. The support plate 2 also slides under the drive of the push rod 44 until the lower surface of the vertically placed support plate 2 coincides with the plane of the road surface. At this time, the first connecting rod 42 is rotated again to apply a thrust to the second connecting rod 43. Since there is no sliding space at the end of the push rod 44, the component force applied to the second connecting rod 43 causes the connection point between the second connecting rod 43 and the push rod 44 to slide to another part of the bifurcation section of the chute 5. During this process, the push rod 44 rotates, and the support plate 2 also rotates until it is in contact with the road surface, completing the laying process of the support plate 2.

[0038] Conversely, the storage support plate 2 rotates in the opposite direction, driving the motor 41 to rotate. The first connecting rod 42 drives the second connecting rod 43 to slide in the opposite direction. The second connecting rod 43 pulls the push rod 44 to rotate in the opposite direction. After the support plate 2 rotates to a vertical position, a force is applied to the second connecting rod 43, causing the push rod 44 to slide downward. The support plate 2 then slides downward and adheres to the side wall of the road surface, completing the storage process.

[0039] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
