Description

Technical Field

[0001] The invention belongs to the technical field of aviation equipment, and in particular relates to an aviation electric wind rod. Background Art

[0002] According to ICAO regulations, the supporting structures of all obstacles within the airport operating area should be set as the lightest and most easily broken, bent or yielded fragile bars, to ensure that when an aircraft collides with an obstacle due to irregular operation, the fragile bars can be quickly destroyed to minimize damage to the aircraft.

[0003] In order to monitor the wind speed and direction at both ends of the airport runway in real time, multiple wind poles are installed in the airport. However, the current wind poles have the following shortcomings: the material of the wind poles is not easy to break, which poses a great hidden danger to aircraft; due to material problems, most wind poles are far away from both ends of the runway, and the reference value of the data is greatly reduced; the existing wind poles have no auxiliary folding device after installation, and it is very difficult to maintain the wind measuring equipment, which is time-consuming and labor-intensive. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides an aviation electric wind pole, which can automatically put down and stand up the wind pole according to the situation, thereby meeting the use requirements.

[0005] The technical solution adopted by the present invention is: In a first aspect, the present invention provides an aviation electric wind pole, which is arranged in an airport operation area and can be automatically tilted and placed, and comprises a movably connected rod and a support, wherein the support is provided with a power module, and the power module controls the movement of the rod relative to the support through a transmission component; The rod is a breakable structure formed by a material with an upper strength limit or a structural connection part with an upper strength limit, and the force exerted on the aircraft by the rod when the aircraft collides with the aircraft does not exceed 45KN.

[0006] In combination with the first aspect, the present invention provides a first implementation manner of the first aspect, wherein the rod is a cylindrical frame structure made of fiberglass reinforced plastic.

[0007] It is worth mentioning that the fiberglass material is the material with an upper strength limit in the above solution, that is, the impact force that causes the material to break is limited to no more than 45KN, but is not limited to breaking at a certain part.

[0008] In combination with the first aspect, the present invention provides a second implementation of the first aspect, wherein the rod is a hollow metal frame structure formed by a main rod and a secondary rod, and the connection between the main rod and the secondary rod is a breakable structure formed by welding or buckling.

[0009] It should be noted that the so-called fragile structure means that after the rod is hit, the entire rod will break or be otherwise damaged, and the force on the aircraft will not exceed 45KN. The breakage or other damage is caused by the connection between the main rod and the auxiliary rod. The main rod is the main rod that forms the rectangular frame structure, and the auxiliary rod is the oblique connecting rod that is staggered and connected between the main rods. The buckle connection is fixed by rivets or bolts.

[0010] In combination with the first aspect, the present invention provides a third implementation of the first aspect, wherein the rod is rotatably connected to the support, the power module is a reduction motor and a transmission gear set arranged on the support, and the reduction motor is transmission-connected to the rod through the transmission gear set.

[0011] In combination with the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the rod is rotatably connected to the support, the power module includes a hydraulic rod with one end hinged to the support, the other end of the hydraulic rod is hinged to the end of the rod, and the power module also includes a hydraulic control system connected to the hydraulic rod.

[0012] In combination with the first aspect, the present invention provides a fifth implementation of the first aspect, wherein the rod is rotatably connected to the support, and the power module includes a traction motor and a winch that are transmission-connected, a pull rope is wound around the winch, and is transmission-connected to the end of the rod through the pull rope.

[0013] In combination with the fifth embodiment of the first aspect, the present invention provides a sixth embodiment of the first aspect, wherein a clamping portion and a roller portion are provided at the end of the rod, the clamping portion is sleeved on the outside of the rod, the roller portion is fixedly connected to the clamping portion, and has a plurality of pulley groups, and the pull rope passes through the pulley group and is transmission-connected to the rod.

[0014] In combination with the sixth embodiment of the first aspect, the present invention provides a seventh embodiment of the first aspect, wherein a wire fixing frame is provided at the bottom of the support, and the pull rope coming out of the winch passes around the roller part and changes direction and then enters the wire fixing frame for fixing.

[0015] In combination with the seventh implementation of the first aspect, the present invention provides an eighth implementation of the first aspect, wherein the support is further provided with a branching frame, and the branching frame is provided with at least two groups of rollers; The roller part includes a first pulley group and a second pulley group with axes arranged in parallel, and also includes a reversing pulley with an axis perpendicular to the first pulley group; After being pulled out from the winch, the pull rope passes through the branching frame, sequentially passes through the first pulley block, the second pulley block, the reversing pulley, the second pulley block, the first pulley block, and then returns to the branching frame, and is introduced from the branching frame into the fixed line frame for fixing; There are at least two sections of pull ropes with opposite movement directions and parallel to each other between the branching frame and the first pulley block.

[0016] It is worth mentioning that the wire distribution frame is used to realize the rope arrangement between the roller part. There are two ways to realize the rotation and lifting control of the rod through the dragging mechanism. That is, the rod is directly pulled by the end of the rope. In addition to the force on the rope itself, the connection between the rope and the rod also needs to ensure stable pulling strength. And through the winding of the pulley group, the rope sleeve is set on the pulley to bear the force, thereby dispersing the force on the entire roller and reducing the risk of end connection breakage.

[0017] The so-called number of rope sections between the branching frame and the first pulley block means that the rope can be wound back and forth multiple times between the roller part and the branching frame, thereby transforming the stress situation of a single rope into multiple rope sections between the two structures to share the stress, thereby further improving stability.

[0018] In combination with several implementations of the first aspect, the present invention provides a ninth implementation of the first aspect, wherein the support is further provided with a fixing fork whose displacement is controlled by a motor, a wedge block is provided inside the fixing fork, and a clamping gap is formed inside the fixing fork where the wedge block is located that is not larger than the outer diameter of the rod; When the rod is pulled upward and tilted from the storage state by the pull rope, when the rod is rotated to the angle with the ground reaching the alignment angle, the fixed fork is displaced and clamped to form a limit, and the internal wedge block pushes the rod from the angle with the ground reaching the alignment angle to vertical to the ground when the fixed fork is continuously displaced.

[0019] It should be noted that the use of a dragging and pulling mechanism to control the flipping and tilting of the rod can reduce the space occupied by the entire device as much as possible, but this dragging method itself uses the gravity of the rod itself to provide a force opposite to the component force of gravity in the rotation direction to achieve pullback / release control. Once the gravity and the direction of the force required for rotation remain perpendicular, that is, the rod is in a vertical state, theoretically, it is impossible to achieve rotation control by pulling the rope.

[0020] Generally, a limit structure is set on the support, that is, when the rod reaches the vertical state, it is fixed by a rod or a stopper, and the pull rope is only used to provide force when the rod moves. The fixed fork structure maintains a movable connection with the support, and will only move to clamp the rod when it reaches the set straightening angle.

[0021] The so-called alignment angle is to set an angle of the rod relative to the ground according to the structural characteristics of the support, which is generally greater than 85 degrees. At this time, the rod is just at the opening of the fixed fork. When the fixed fork is controlled to move relative to the support, its opening moves toward the outer surface of the rod and clamps the rod in the opening, and as the fixed fork continues to move, it goes deeper into the inside of the opening.

[0022] Since one or two paired wedges are provided on the inner side of the opening of the fixed fork, the gap in the opening itself is kept at a fixed value, but the center line of the clamping gap is always changing, and the width of the space defined by its external structure remains unchanged when the entire fixed fork itself moves relative to the support. However, the presence of the wedges causes the rod in the clamping gap to be continuously thrust until the fixed fork stops moving and the rod moves to a vertical state.

[0023] Similarly, when the rod needs to be lowered, the fixed fork is moved and pushed from a perpendicular angle to the straight angle through the wedge. At this time, since there is a certain angle between the rod itself and the direction of gravity, the rod can be tilted and rotated by releasing the pull rope.

[0024] The beneficial effects of the present invention are: (1) The present invention provides a rotating rod and a support structure, and realizes automatic control of erection and laying down through a power module, thereby meeting the requirements for erection poles in aviation venues. When a situation occurs, all wind poles can be immediately lowered through the control system to avoid blocking the aircraft; (2) The present invention uses a whole rod solution made of easily breakable materials, which not only has a lighter weight and better structural strength, but also can be quickly damaged and broken when subjected to an impact exceeding the maximum load, thus meeting the use requirements; (3) The present invention limits the use of metal composite rods, and the vulnerable parts formed by the connection between the main rod and the auxiliary rod can also break quickly when subjected to overload impact force. The entire rod is a hollow composite structure, which is light in weight and relatively stable in the load-bearing state. (4) The present invention can realize stable motion control of the rod in a limited space by setting the pull rope type dragging mechanism and the roller structure. At the same time, the setting mode of the plurality of pulley groups of the roller and the setting mode of the reversing rotation of the pull rope make the release of the rod more stable, the force of the entire pull rope is more uniform, and the strength requirement of the connection of the rod itself is reduced; (5) The present invention, through the fixed fork structure, can target the special transmission mechanism of the power module such as the pull rope, not only to maintain a good limiting stability effect on the rod in the vertical state, but also to provide a deflection guide for the rod during the limiting / disengaging process, so that the rod itself has a certain component force in the direction of gravity in the initial state, so as to have a deflection tendency.

[0034] Embodiment 1: This embodiment discloses an aviation electric wind pole, which is arranged on both sides of an airport runway and is used to provide a certain installation height so that a wind measuring device can obtain the wind speed and wind direction of each monitoring point near the runway in real time.

[0035] The existing wind pole is a fixed structure. In order to meet the standard requirements of the ICAO for easy breakage, an easy-to-break rod structure is adopted. The aviation electric wind pole structure in this embodiment includes a rod 1 and a support 2. The rod 1 is the main structure of the wind pole, and a wind measuring device is provided at one end thereof, and the other end is in a movable connection with the support 2.

[0036] The rod 1 has a certain length, and the support 2 is relatively low in height, and is only used to form a limited movable connection relationship with the rod 1. The support 2 provides support force and movable limiting effect to the rod 1.

[0037] A power module 3 is provided on the support 2, and the power module 3 controls the rod 1 to perform controlled movement relative to the support 2, and its state is mainly divided into an upright working state and a stored tilting state. The power module 3 has an electronic control system, which can be controlled remotely or automatically controlled by program settings. The rod 1 is normally in an upright working state, and when the wind measurement equipment on the rod 1 needs to be maintained or needs to be quickly laid down due to a temporary accident, the power module 3 is used to lay the rod 1 down to a certain lower limit angle for disposal. There is also a button on the power module 3, which can be manually operated to lay down the rod 1 in an emergency.

[0038] Furthermore, the rod 1 is an easy-to-break structure, including two configurations, the first being an integrated easy-to-break rod 1 structure formed by a material with an upper strength limit, and the second being an easy-to-break structure formed by a structural connection portion with an upper strength limit. In both configurations, the rod 1 has a maximum lateral impact bearing capacity, that is, the force exerted on the aircraft by the collision of the aircraft on the rod 1 does not exceed 45KN.

[0039] Specifically, the rod 1 shall not break or deform when exposed to wind or jet streams at speeds up to 480 km / h (260 knots), but shall immediately break, bend or yield when subjected to a sudden impact force from an aircraft weighing 3000 kg flying at a speed of 140 km / h (75 knots) or taxiing on the ground at a speed of 50 km / h (27 knots). The force exerted by the frangible rod on the aircraft during impact shall not exceed 45 kN, and the maximum energy transmitted to the aircraft during the collision between the aircraft and the frangible rod shall not exceed 55 kJ.

[0040] In the first method, refer to Figure 1-Figure 7 In the figure, the rod 1 is a cylindrical frame structure made of glass fiber reinforced plastic. Specifically, it is made of glass fiber roving as a reinforcing material and unsaturated polyester resin as a matrix through a pultrusion process. When a collision occurs, the stress concentration point of this material will be destroyed earlier than the normal structure, resulting in the disintegration of the entire easy-to-break rod structure. The position of the stress concentration point is optimized after calculation and experimental verification, so that the easy-to-break rod meets the relevant provisions of aviation standards.

[0041] In the second method, refer to Figure 8 and Fig. 9, the rod 1 is a hollow metal frame structure formed by a main rod and a secondary rod, and the connection between the main rod and the secondary rod is a breakable structure formed by welding or buckling. Specifically, the main rod is made of aluminum alloy, and the main frame structure of the breakable rod is formed by welding or buckling the main rod and the secondary rod. It can be designed to be a single-section or multi-section connection according to the height of the wind pole. During the processing, stress concentration points are provided on the main rod, secondary rod and fuse bolts of the breakable rod. Through calculation, under normal load, the stress concentration point will not affect the force or performance of the breakable rod; when an impact occurs, these stress concentration points will be destroyed earlier than the normal structure, thereby causing the entire breakable rod structure to disintegrate. The position of the stress concentration point is optimized after calculation and experimental verification. Furthermore, the rod 1 and the support 2 are in a rotational connection relationship, that is, a rotating hoop 4 is provided near the lower end of the rod 1. In the scheme of the rod 1 using a cylindrical fiberglass material, the rotating hoop 4 is sleeved on the surface of the rod 1 and clamped and fixed by bolts. In the scheme of the rod 1 using a hollow metal frame structure, the rotating hoop 4 is a fixed plate structure fixed to the surface of its main rod by bolts or rivets, and there are rotating shafts on both sides of the fixed plate, which are rotationally limitedly connected to the support 2 through the rotating shafts.

[0042] Further, refer to Figure 1-Figure 9 The support 2 is a door-type support structure with an avoidance gap in the middle for the rod 1 to enter. A limit frame 15 structure is provided on the support. The limit frame 15 is an automatic mechanism that can form a better limiting effect by blocking the rod 1 from rotating outward when the rod 1 is raised and maintained in an upright state. The limit frame 15 shown in the figure is only a baffle arranged on one side of the support 2. In actual use, a limit frame 15 for limiting excessive rotation of the rod 1 can be further provided on the inner side of the avoidance space of the support 2, so that when the rod 1 is turned from a tilted state to an upright state, it is limited to only be able to rotate clockwise to 90 degrees.

[0043] Furthermore, the power module 3 is arranged at the other end of the movable range of the rod 1, and is connected to the rod 1 through a transmission assembly.

[0044] In one embodiment, the power module 3 is a reduction motor, and a gear set is provided at the rotation connection between the rod 1 and the support 2, and the reduction motor is connected to the rod 1 through the gear set. However, since the rotation connection between the rod 1 and the support 2 is close to the end of the rod 1, the reduction motor bears the component force of the gravity of the rod 1 in the rotation direction during rotation, resulting in a large load. Therefore, in actual use, the self-locking effect can be achieved by increasing the gear ratio of the gear set or adopting a worm gear structure.

[0045] In one embodiment, the power module 3 is a hydraulic rod or a push rod structure of other power forms arranged on the support 2, and is hinged with the support 2 and the rod 1 at the same time, and the directional rotation control of the rod 1 is achieved by extending / contracting the hydraulic rod or the push rod.

[0046] In one embodiment, referring to Figure 1-Figure 10 The power module 3 has a towing mechanism, that is, the controlled release and lifting of the rod 1 is achieved by using one or more pull ropes 7 and the self-gravity of the rod 1.

[0047] Specifically, the power module 3 is a rectangular housing fixed on the support 2, and a tug motor 8 and a winch 9 are provided inside the housing, and an opening is provided at the lower part of the housing for the winch 9 to be pulled out with a pull rope 7 wound thereon, and the pull rope 7 is connected to the end of the rod 1 through the pull rope 7. The end of the rod 1 is provided with a clamping portion 5 and a roller portion 6, the clamping portion 5 is sleeved outside the rod 1, the roller portion 6 is fixedly connected to the clamping portion 5, and has a plurality of pulley blocks, and the pull rope 7 passes through the pulley block and is connected to the rod 1 through the pulley block.

[0048] Reference Figure 3 and Figure 7 , a fixed wire frame 11 is arranged at the bottom of the support 2, and the pull rope 7 coming out of the capstan 9 passes around the roller part 6 and changes direction before entering the fixed wire frame 11 for fixing. A branching frame 10 is also arranged on the support 2, and at least two groups of rollers are arranged on the branching frame 10; the roller part 6 includes a first pulley group 12 and a second pulley group 13 with axes parallel to each other, and also includes a reversing pulley 14 with an axis perpendicular to the first pulley group 12; after the pull rope 7 is pulled out from the capstan 9, it passes through the branching frame 10 and passes through the first pulley group 12, the second pulley group 13, the reversing pulley 14, the second pulley group 13, and the first pulley group 12 in sequence, and then returns to the branching frame 10, and is introduced from the branching frame 10 into the fixed wire frame 11 for fixing; there are at least two sections of pull rope 7 with opposite and parallel movement directions between the branching frame 10 and the first pulley group 12.

[0049] In the initial state, the rod 1 remains in an upright state. At this time, the rod 1 is fixed by the limit frame 15 or other fixed structure on the support 2 in cooperation with the pull rope 7. When the rod 1 needs to be tilted, the limit frame 15 is opened, and the pull rope 7 on the winch 9 is released to make the rod 1 tilt clockwise. At this time, the torque of the towing motor 8 is controlled to keep the rod 1 tilting at a uniform and stable speed, and after tilting to a certain angle, the towing motor 8 is used to fix the rod 1 to keep it stable, or an additional stopper is provided on the support 2, which can abut against the stopper when the rod 1 is released to the corresponding angle to achieve limiting and fixing.

[0050] The wire fixing frame 11 is a rod at the bottom of the fixed support 2. One end of the pull rope 7 is fixed on the wire fixing frame 11, and the other end enters the roller part 6 from the pulley on the wire splitting frame 10, then goes back to the wire splitting frame 10 and enters the capstan 9. When the capstan 9 rotates, the pull rope 7 on the wire fixing frame 11 remains stationary, and is released and tightened by the pull rope 7 on the capstan 9.

[0051] Furthermore, a manual operation method is provided. The power module 3 in this embodiment is controlled by an electrical control cabinet, which has a start button, a stop button and an emergency stop button. The start knob is divided into three gears: lay down, stop and raise, and the default is the stop state. When the rod 1 needs to be laid down, first pull out the positioning lock pin on the limit frame 15, and then turn the knob to the laying side. At this time, the power module 3 starts to slowly release the pull rope 7, and the pull rope 7 drives the pulley to make the wind rod slowly tilt and fall. When it reaches the lower limit, the electrical control cabinet receives the lower limit signal and automatically disconnects the power supply of the power module 3. The power module 3 stops releasing the pull rope 7 and remains unchanged.

[0052] After the maintenance of the rod 1 is completed, the knob switch is turned to the raising position. At this time, the power module 3 will reverse and tighten the pull rope 7. The pull rope 7 drives the pulley to slowly raise the wind rod until it reaches the upper limit position. The electric control cabinet receives the upper limit signal and automatically disconnects the power supply of the power module 3. The power module 3 stops moving and remains unchanged, and the positioning lock pin is inserted.

[0053] Furthermore, the support 2 is also provided with a fixed fork 16 whose displacement is controlled by a motor, and a wedge block is provided on the inner side of the fixed fork 16. A clamping gap no larger than the outer diameter of the rod 1 is formed on the inner side of the fixed fork 16 where the wedge block is located; when the rod 1 is pulled upward and tilted by the pull rope 7 from the storage state, when the rod 1 is rotated to the angle with the ground reaching the alignment angle, the fixed fork 16 displaces and clamps the rod 1 to form a limit, and the internal wedge block pushes the rod 1 from the angle with the ground reaching the alignment angle to be perpendicular to the ground when the fixed fork 16 is continuously displaced.

[0054] Reference Fig.10 , the figure shows a schematic diagram of the plane principle between the fixing fork 16 and the rod 1. It can be seen that the fixing fork 16 itself has a groove with equal gap, and the gap of the groove is originally larger than the maximum size of the cross section of the rod 1. A pair of wedges are provided on the inner wall of the groove, and the wedges have parallel inclined surfaces. They are installed on the two sides of the groove so that the gap in the groove is reduced to be consistent with the cross-sectional size of the rod 1. The inclined surfaces of the two wedges are the clamping gap. The midline of the clamping gap becomes oblique relative to the original gap of the groove, that is, Fig.10 In the first state, when the rod 1 itself is at the alignment angle, the rod 1 can just enter the groove opening of the fixing fork 16, and then as the fixing fork 16 continues to rotate downward, the rod 1 changes to the state on the right side of the figure, that is, when viewed from the horizontal direction, the rod 1 has achieved a certain degree of rotation and alignment.

[0055] It should be noted that Fig.10 The figure is a simple explanation of the principle. When the rod 1 is tilted, the fixing fork 16 itself is in an upright state. When the rod 1 needs to be lifted and erected, when the rod 1 reaches the straightening angle, the fixing fork 16 is rotated so that the rod 1 enters the fixing fork 16 from the groove opening. However, at this time, the fixing fork 16 does not Fig.10 The left side of the diagram shows the completeness of the top view, but only contacts the surface of the rod 1 at the opening of the groove. When rotating, from a top view, the fixing fork 16 remains fixed in the horizontal direction, and the rod 1 also remains stable in the vertical direction in the figure, but with the continuous rotation of the fixing fork 16, it moves to a certain extent in the left and right directions in the figure. When the fixing fork 16 rotates to a horizontal state and maintains a vertical connection with the support 2, the rod 1 can be just straightened to an upright state. At this time, refer to Fig.10 In the middle right state, the rod 1 is always in contact with the wedge block of the fixing fork 16 and remains fixed in position.

[0056] This arrangement of the fixed fork 16 structure can not only achieve clamping and limiting of the rod 1 in the upright state, thereby replacing the limit frame 15 structure in the above-mentioned embodiment, but also can achieve a certain angle of adjustment through the wedge block, so that when the rod 1 is tilted from the upright state, the rod 1 can be given motion control to swing to a certain angle in the tilting direction. When the rod 1 is separated from the fixed fork 16, the pull rope 7 can be tightened. At this time, since the rod 1 has a certain inclination angle, the component of its gravity in the rotation direction can cause the rod 1 to tilt in a controlled manner.

[0057] It should be noted that when the rod 1 is fixed and aligned by the fixing fork 16, the pull rope 7 cooperates to achieve control. Among them, when the rod 1 turns from the tilted state to the upright state, the pull rope 7 always provides the effect of offsetting its gravity component force before the rod 1 rotates to the swing angle. When the rod 1 rotates to the swing angle, the towing motor 8 reduces the rotation force (the towing motor 8 in this embodiment has a torque sensor for closed-loop control, which can detect the reaction force given by the rod 1 in real time, thereby calculating the force required to keep the rod 1 rotating at a uniform speed, and frequency conversion control at any time), keeping the rod 1 in a stable state. As the fixing fork 16 continuously pushes the rod 1 to move, the pull rope 7 suddenly unloads the force, and the towing motor 8 maintains the lowest degree of rotation force to keep the pull rope 7 in a tensioned state until the rod 1 is aligned and the pull rope 7 remains stable and motionless.

[0058] When the rod 1 changes from an upright state to a tilted state, the fixed fork 16 keeps in contact with the rod 1 and rotates to the adjustment angle, the towing motor 8 always keeps the tension on the pull rope 7, and when the adjustment angle is reached, the rotational force is increased to restore to the component force of the weight of the rod 1 in the rotation direction at this angle, thereby ensuring that the rod 1 is always kept stable when the fixed fork 16 is separated from the rod 1, and then the rotational force is adjusted to slowly and evenly release the rod 1 until the tilting angle.

[0059] The present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention. The above specific implementations should not be understood as limiting the scope of protection of the present invention.
