Description

Technical Field

[0001] The invention relates to the technical field of civil aviation airport equipment, and in particular to an airport easily breakable rod and a supporting device. Background Art

[0002] If an aircraft deviates from its planned route due to unexpected reasons, it will collide with equipment and facilities on the ground. These equipment and facilities themselves or their supports must be easy to break to avoid damage to the aircraft.

[0003] Airport ground equipment and facilities are supported by steel frames and placed in designated locations. The design purpose is to support the heaviest navigation aids with the lightest possible foldable poles. However, when subjected to accidental impacts from any direction, the foldable poles should be easy to break and shatter to minimize structural damage to the aircraft. In the event of a collision, the foldable poles must break, bend or yield, and not entangle the aircraft to prevent limiting the safe maneuverability of the aircraft.

[0004] For a breakable bar that may collide with an aircraft taxiing on the ground, it must be easy to break when hit by an aircraft weighing 3,000 kg and traveling at a speed of 50 km / h. During a collision, the force applied by the breakable bar to the aircraft should not exceed 45 kN; at the moment of contact between the aircraft and the breakable bar (about 100 ms), the maximum energy applied by the breakable bar to the aircraft should not exceed 55 kJ.

[0005] Most of the existing equipment supports are made of welded or assembled steel structures. The product material itself is relatively hard and can cause penetrating damage to the aircraft. In addition, if the existing easily breakable materials are directly used to splice components to form supports, the structure is simple and the stability is not strong. Summary of the invention

[0006] The object of the present invention is to provide an efficient airport breakable pole and supporting device.

[0007] In order to solve the above technical problems, the present invention provides an airport easily breakable pole, comprising a main pole and a clamping structure;

[0008] The clamping structure includes a first clamping structure and a second clamping structure used in conjunction with each other;

[0009] The first clamping structure and the second clamping structure are respectively mounted at two ends of the main rod;

[0010] The first clamping structure comprises a first clamping main body rod, the first end of the first clamping main body rod is bent outward to form a first clamping groove, and a positioning protrusion is arranged on the inner side of the tail end of the first clamping main body rod;

[0011] The second clamping structure comprises a second clamping main body rod, the first end of the second clamping main body rod is bent outward to form a second clamping groove, and the second clamping groove is provided with a positioning groove adapted to the positioning protrusion; the second clamping main body rod is provided with clamp grooves on both sides of the second clamping groove;

[0012] The first clamping groove is used for inserting the tail end of the second clamping main body rod, the second clamping groove is used for inserting the tail end of the first clamping main body rod, the positioning groove is used for embedding the positioning protrusion, and the clamping groove is formed by clamping.

[0013] Preferably, the main rod comprises a reinforcement structure and two vertically parallel supporting rods;

[0014] The two support rods are connected via a reinforcement structure.

[0015] Preferably, the outer sides of the two support rods are each provided with an extension rod extending outwards for a certain distance;

[0016] The middle position of the first clamping main body rod is connected to one of the extension rods, and the middle position of the second clamping main body rod is connected to the other extension rod.

[0017] Preferably, the first end of the first clamping main body rod is bent outward by 90°;

[0018] The first end of the second clamping main body rod is bent outwards by 90 degrees.

[0019] Preferably, the width of the first clamping groove is equal to the width of the tail end of the second clamping main body rod;

[0020] The width of the second clamping groove is equal to the sum of the widths of the tail end of the first clamping main body rod and the positioning protrusion.

[0021] Preferably, the angles between the first clamping main body rod and the second clamping main body rod and the extension rod are not 90°.

[0022] Preferably, the head end of the first clamping main body rod and the tail end of the second clamping main body rod are both facing the same side of the main body rod.

[0023] Preferably, the support rod is a hollow hexagonal tube.

[0024] Preferably, the reinforcement structure is an S-shaped reinforcement rib.

[0025] The present invention also provides a support device, in which all the airport easily breakable rods are enclosed in sequence;

[0026] The first clamping structure of each airport breakable rod is connected to the second clamping structure: the tail end of the first clamping main rod of each airport breakable rod is inserted into the second clamping groove of the adjacent airport breakable rod, and the positioning groove is embedded in the corresponding positioning protrusion; at the same time, the first clamping groove of the airport breakable rod is inserted by the tail end of the second clamping main rod of the adjacent airport breakable rod;

[0027] The first clamping structure and the second clamping structure connected to each other are clamped and fixed by hydraulic clamps to form a clamp groove.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The invention is easy to break: the product itself is made of aluminum alloy, which is relatively soft and easily deformed after being hit, and will not cause penetrating damage to the aircraft;

[0030] 2. The splicing structure of the present invention adopts an anti-slip design, and the splicing is simple. After being pressed with pressure pliers, no product deformation will occur, and the overall stability is improved while ensuring the product's easy-to-break performance.
