Technical Field

The invention relates to the technical field of helicopters, in particular to a fire-fighting bomb hanging bomb bracket for a helicopter.

Background

The ability to fight fires in high-rise buildings has become an important indicator of the level and effectiveness of fire protection modernization in a country, region or city. The helicopter is widely applied to forest fire fighting firstly, and plays an important role in forest fire fighting and disaster relief due to the operating characteristic and flexible maneuvering type of the helicopter. In the fire extinguishing and disaster relief operation of high-rise buildings, the helicopter has the characteristics of maneuvering and flexible flight, including less limitation on taking-off and landing conditions, hovering in the air, capability of moving forwards and backwards in any direction and the like, and has the irreplaceable advantages compared with fixed-wing fire-fighting airplanes and fire-fighting vehicles. Especially in fire suppression of forests, urban high-rise buildings, ships and the like, the helicopter can restrict the characteristics of rapid fire spread, large consumption of a suppression agent and the like of certain fires and complete the suppression work as early as possible. At present, when a helicopter is used for fire extinguishing, a fire-fighting bomb suspension bracket is generally arranged on the helicopter to fixedly install the fire-fighting bomb. The existing fire bomb suspension bracket often causes larger energy consumption of a helicopter in the flying process due to the overlarge weight of the existing fire bomb suspension bracket. However, if the fire-fighting bomb suspension bracket is lightened once, the intensity of the fire-fighting bomb suspension bracket is difficult to ensure because the resistance received by the fire-fighting bomb suspension bracket is large when the speed of the airplane is high in the flying process.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, provides a fire-fighting bomb hanging bracket for a helicopter, and solves the problem that the energy consumption of the helicopter is high in the flying process due to the fact that the existing fire-fighting bomb hanging bracket for the helicopter is unreasonable in design and overlarge in self weight.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a helicopter fire control bullet string bullet support, includes fire control bullet fixed bolster and connects the skeleton, connect the skeleton through connecting block fixed mounting in the helicopter frame, fire control bullet fixed bolster pass through connecting piece fixed mounting in connect on the skeleton, fire control bullet fixed bolster is including going up shellproof fixed bolster, the shellproof fixed bolster that disappears down and linking bridge, go up shellproof fixed bolster, disappear down and pass through linking bridge fixed connection between the shellproof fixed bolster, the both ends of going up shellproof fixed bolster and the shellproof fixed bolster that disappears down all are equipped with fire control bullet fixing bolt, and the fire control bullet passes through fire control bullet fixing bolt is fixed in go up on shellproof fixed bolster and the shellproof fixed.

Furthermore, one end of the connecting block is fixedly installed on the connecting framework, the other end of the connecting block is provided with a mounting hole matched with a helicopter frame, and the helicopter frame penetrates through the mounting hole to fixedly install the connecting framework on the helicopter frame.

Furthermore, the reinforcing plate and the connecting plates are integrally formed between the two connecting plates, and a plurality of lightening holes are uniformly formed in the reinforcing plate.

Furthermore, one end of the connecting plate and the upper-digestion-prevention fixing support are integrally formed at the lower end of the upper-digestion-prevention fixing support, and the other end of the connecting plate is fixedly arranged on the lower-digestion-prevention fixing support through bolts and nuts.

Further, a U-shaped groove is formed in the top of the upper bulletproof fixing support and the upper bulletproof fixing support in an integrated mode, bolt through holes are formed in the two sides of the U-shaped groove, installation through holes matched with the bolt through holes are formed in the connecting framework, when the fire-fighting bomb fixing support is installed on the connecting framework, the bolt through holes are aligned with the installation through holes, fixing bolts are driven into the bolt through holes and the installation through holes, the fixing bolts penetrate through the U-shaped groove, and nuts matched with the fixing bolts are driven into the extending ends of the fixing bolts to fixedly install the fire-fighting bomb fixing support on the connecting framework.

Furthermore, a plurality of lightening holes are uniformly formed in the end faces of the upper and lower fire-fighting bulletproof fixing supports and the lower fire-fighting bulletproof fixing support.

Furthermore, the connecting support is composed of two parallel connecting plates, one end of each connecting plate is fixed on the upper fire-fighting bulletproof fixing support, the other end of each connecting plate is fixedly arranged on the lower fire-fighting bulletproof fixing support, and a reinforcing plate is arranged between the two connecting plates.

The fire-fighting bomb mounting device is simple in structure and reasonable in design, reduces the total mass of the whole bomb-hanging device on the basis of ensuring the mounting strength of the fire-fighting bomb, and greatly reduces the energy consumption of a helicopter in the flying process. According to the invention, the connecting framework is fixedly arranged on the helicopter frame through the connecting block, the U-shaped groove is formed in the top of the upper fire-fighting bomb fixing support, the fire-fighting bomb fixing support is fixedly arranged on the connecting framework through the U-shaped groove, and finally the fire-fighting bombs are fixedly arranged at two ends of the upper fire-fighting bomb fixing support and the lower fire-fighting bomb fixing support through the fixing bolts, so that the fixed installation of the fire-fighting bombs is completed. According to the invention, the connecting framework with lighter weight is fixed on the helicopter frame, and then the fire-fighting bomb fixing support is fixedly arranged on the connecting framework, so that the fixed installation of the fire-fighting bomb is completed, the weight of the whole fire-fighting bomb fixing device is reduced. Meanwhile, lightening holes are formed in the upper fire-fighting bomb fixing support, the lower fire-fighting bomb fixing support and the connecting plate, and the total weight of the whole device is further reduced.
