Description
Technical Field
The invention belongs to the field of structural design, and particularly relates to an aerostat inner suspension cable structure capable of adjusting tension externally, which is suitable for the design of a connecting structure of an aerostat air bag and a suspension frame.
Background
The aerostat mainly comprises an air bag, a hanging rack (or a pod), a tail wing, a rigging and a nose cone. In order to disperse the concentrated force of the hanging rack on the air bag, an inner curtain cloth is generally arranged on the upper part in the air bag and is connected with the hanging rack through a plurality of inner hanging ropes. The initial length of the inner sling needs to be matched with the theoretical space of the inflated saturated loaded air bag, if the length is too long, the load of the hanging rack cannot be transferred, and if the length is too short, the attaching clamp load is generated on the curtain cloth. At present, the adjustment of the internal hoisting cable needs to be completed inside the air bag, and a worker fills air into the air bag and then enters the air bag to adjust the internal hoisting cable. When helium is filled in the air bag, the length of the inner sling can not be matched with the theoretical space of the air bag due to the change of the shape of the air bag, and the potential safety hazard that the tensioning degree is inconsistent and the tension generated on the inner curtain cloth is inconsistent exists. When the air bag is loaded, the theoretical space of the air bag is further changed, the tension of the inner sling is influenced by creep deformation generated in the length of the loaded inner sling, and in the actual use process, the tension of the inner sling is not matched with the theoretical value, so that the local tension is too high, and the safety of a sphere is influenced. In order to solve the technical bottleneck, the internal sling structure of the aerostat capable of adjusting the tension externally is designed, the tension of each internal sling is adjusted outside the air bag, so that the internal sling is stressed uniformly, and the use safety of the internal sling is improved.
Disclosure of Invention
Object of the Invention
The invention is mainly used for the design of the connecting structure of the aerostat air bag and the hanging rack. Through increasing the flexible cloth cover of clamp on the gasbag, move the stores pylon hanging point to the stores pylon frame middle part by the stores pylon top and increase on hanging the point and press from both sides adjusting device, make former interior suspension cable structure extend to the gasbag outside, possess the inside preliminary regulation of suspension cable tension accessible in every when guaranteeing air bag structure security and gas tightness in accommodation process, outside real-time online adjustment's function, it is even to guarantee every interior suspension cable atress, the security of suspension cable structure and interior curtain cloth structure in increasing substantially.
Technical solution of the invention
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a but tensile aerostatics internal sling structure of external adjustment, including the inside section of many interior slings of top and gasbag internal top inner curtain cloth pull ring connection, every internal sling inside section lower extreme is connected to the cloth cover top connection, still include bottom open-ended soft flexible cloth cover, flexible cloth cover top is pressed from both sides tightly by cloth cover top connection and cloth cover lower clutch, cloth cover top connection and cloth cover lower clutch can dismantle the connection, internal sling outside section one end is connected with cloth cover lower clutch, the other end is worn out and is connected with the adjusting device one end of adjustable internal sling elasticity from the gasbag bottom, the adjusting device other end is connected to on the typical frame of stores pylon, the opening of flexible cloth cover bottom covers the hole that forms and is connected with gasbag sealing when wearing out the gasbag bottom with internal sling outside section.
Preferably, a tension sensor is arranged on the outer section of the inner sling.
Preferably, the opening at the bottom end of the telescopic cloth cover is hermetically connected with the air bag in a gluing or heat sealing mode.
Preferably, the adjusting device is a turnbuckle actuator cylinder or other telescopic structure.
Preferably, cloth cover top connection and cloth cover bottom connection all include annular connecting portion, and connecting portion one end an organic whole is connected with flat construction's fixed part, and a plurality of connecting holes have been seted up to corresponding position on the two fixed part, can dismantle the connection with the two through screw bolt and nut.
THE ADVANTAGES OF THE PRESENT INVENTION
The invention has the advantages that:
(1) the internal suspension cable structure of tradition passes through gasbag bottom connector for the internal suspension cable and is connected with the stores pylon, and internal suspension cable length can only fill the inside regulation of back staff entering at the gasbag, and the inside helium during operation staff that fills of gasbag can't get into, can't adjust its length and tension when the obvious increase of suspension cable stress than other internal suspension cables in single internal suspension cable appear. The structure can realize real-time online adjustment of the length and the tension of each internal sling by additionally arranging the adjusting device outside the air bag.
(2) The traditional internal sling adjustment is carried out under the condition that no load is filled with air inside the air bag, the appearance of the air bag can change under the condition that helium is filled in the air bag under load, the length of the original internal sling is adjusted to be not matched with the actual use working condition, meanwhile, the creep in the use process of the internal sling can also change the length of the internal sling, the tension of the internal sling can be comprehensively influenced under the above conditions, the stress of the internal sling structure and the internal curtain structure is enabled to be uneven, stress concentration is generated, the internal sling is enabled to be broken when serious, the internal curtain layout part is torn or the structure is disabled, and great potential safety hazards are brought to the ball body structure. The structure can adjust the tension of each internal sling on line in real time through an external adjusting device, ensures that the internal sling structure and the internal curtain fabric structure are stressed uniformly, and greatly improves the safety of the ball structure.
(3) By additionally clamping the tension sensor in the internal sling structure, the tension of each internal sling can be monitored on line in real time. Because the structure extends the inner sling structure to the outside of the air bag, and each inner sling is independently arranged, a tension sensor can be additionally arranged in a force transmission system, the tension of a single inner sling can be monitored in real time, and when the tension of the inner sling reaches the upper limit or the lower limit of a set value, an alarm is given out to perform manual intervention.
(4) When traditional structure is when interior cable length needs the regulation in the use, need retrieve spheroid helium, fill the back staff of air and get into inside regulation, consume a large amount of manpower and material resources. The structure can realize real-time online adjustment of the outer part of the inner suspension cable, and reduce the use cost.
