Description

Technical Field

[0001] The invention relates to the technical field of helicopters, in particular to a helicopter fire-fighting bomb hanging bracket. Background Art

[0002] The ability to extinguish fires in high-rise buildings has become an important indicator for measuring and testing the modernization level and combat effectiveness of a country, region or city's firefighting. Helicopters were first widely used in forest fire fighting because of their maneuverability and flexible maneuverability, playing an important role in forest fire fighting and disaster relief. In high-rise building fire fighting and disaster relief operations, helicopters have flexible and maneuverable flight characteristics, including fewer restrictions on take-off and landing conditions, hovering in the air, and the ability to move forward and backward in any direction. Compared with fixed-wing firefighting aircraft and fire trucks, they have irreplaceable advantages. Especially in the fire fighting of forests, urban high-rise buildings, ships, etc., helicopters can restrict the characteristics of some fires such as fast spread of fire and large consumption of firefighting agents, and complete the firefighting work as soon as possible. At present, when using helicopters to extinguish fires, it is generally adopted to set a fire bomb suspension bracket on the helicopter to fix the fire bomb. The existing fire bomb suspension bracket often consumes a lot of energy during the flight due to its own excessive weight. However, if the fire bomb suspension bracket is blindly reduced, the fire bomb suspension bracket will receive a large resistance due to the high speed of the aircraft during the flight, and it is difficult to ensure its strength. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a helicopter fire bomb hanging bracket, which solves the problem that the fire bomb hanging bracket of the existing helicopter is not designed reasonably and its own weight is too large, resulting in high energy consumption of the helicopter during flight.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A helicopter fire bomb hanging bracket comprises a fire bomb fixing bracket and a connecting frame, wherein the connecting frame is fixedly mounted on a helicopter frame via a connecting block, and the fire bomb fixing bracket is fixedly mounted on the connecting frame via a connecting piece, and the fire bomb fixing bracket comprises an upper fire bomb fixing bracket, a lower fire bomb fixing bracket and a connecting bracket, wherein the upper fire bomb fixing bracket and the lower fire bomb fixing bracket are fixedly connected via the connecting bracket, and both ends of the upper fire bomb fixing bracket and the lower fire bomb fixing bracket are provided with fire bomb fixing bolts, and the fire bomb is fixed to the upper fire bomb fixing bracket and the lower fire bomb fixing bracket via the fire bomb fixing bolts.

[0006] Furthermore, one end of the connection block is fixedly mounted on the connection frame, and the other end is provided with a mounting hole matching the helicopter frame, and the helicopter frame is fixedly mounted on the helicopter frame through the mounting hole.

[0007] Furthermore, the reinforcing plate and the connecting plate are integrally formed between the two connecting plates, and a plurality of weight-reducing holes are evenly opened on the reinforcing plate.

[0008] Furthermore, one end of the connecting plate is integrally formed with the upper fire bomb fixing bracket at the lower end of the upper fire bomb fixing bracket, and the other end is fixedly mounted on the lower fire bomb fixing bracket by bolts and nuts.

[0009] Furthermore, a U-shaped groove is integrally formed on the top of the upper fire bomb fixing bracket and the upper fire bomb fixing bracket, bolt holes are provided on both sides of the U-shaped groove, and mounting holes matching the bolt holes are provided on the connecting frame. When the fire bomb fixing bracket is installed on the connecting frame, the bolt holes are aligned with the mounting holes, and then fixing bolts are driven into the bolt holes and the mounting holes. The fixing bolts pass through the U-shaped groove, and then a nut matching the fixing bolt is driven into the protruding end of the fixing bolt to fix the fire bomb fixing bracket on the connecting frame.

[0010] Furthermore, a plurality of weight-reducing holes are evenly arranged on the end surfaces of the upper fire-fighting bomb fixing bracket and the lower fire-fighting bomb fixing bracket.

[0011] Furthermore, the connecting bracket is composed of two connecting plates parallel to each other, one end of the connecting plate is fixed to the upper fire bomb fixing bracket, and the other end is fixedly installed on the lower fire bomb fixing bracket, and a reinforcing plate is provided between the two connecting plates.

[0012] The present invention has a simple structure and a reasonable design. On the basis of ensuring the installation strength of the fire bomb, the total mass of the entire bomb hanging device is reduced, and the energy consumption of the helicopter during flight is greatly reduced. In the present invention, the connecting frame is fixedly installed on the helicopter frame through a connecting block, and then a U-shaped groove is set on the top of the upper fire bomb fixing bracket, and the fire bomb fixing bracket is fixedly installed on the connecting frame through the U-shaped groove. Finally, the fire bomb is fixedly installed on the upper fire bomb fixing bracket and the two ends of the lower fire bomb fixing bracket by fixing bolts to complete the fixed installation of the fire bomb. In the present invention, a lighter connecting frame is fixed on the helicopter frame, and then the fire bomb fixing bracket is fixedly installed on the connecting frame, so as to complete the fixed installation of the fire bomb, and the weight of the entire fire bomb fixing device is reduced. In the present invention, the upper fire bomb fixing bracket and the lower fire bomb fixing bracket for fixing the fire bomb are connected by a connecting plate, and a reinforcing plate is provided between the connecting plates, so as to ensure the strength of the entire device, so that it can be used in a use environment with a faster flight speed. At the same time, weight reduction holes are opened on the upper fire bomb fixing bracket, the lower fire bomb fixing bracket and the connecting plate, and the total weight of the entire device is further reduced.
