Specific embodiment
The present invention is described further below in conjunction with attached drawing:
The present embodiment includes gondola ontology, and gondola ontology is connect by lifting rope 14 with the hoisting mechanism on helicopter.More than
For common structure in the prior art, details are not described herein.
The innovation of the invention consists in that being improved hoisting mechanism and structure for pod.
In the prior art, the intensity of the included hoisting mechanism of pure helicopter is lower, it is difficult to undertake the gondola liter of big load
Drop task, and the Special fire-fighting helicopter of built-in large-scale hoist engine is expensive, in this regard, using external hoist engine in the present invention
The mode of structure realizes the function that big load lifting (i.e. gondola lifting) is carried out on pure helicopter.In the present invention, it is promoted
The structure of mechanism includes upper plate 9, lower plate 10 and hoist engine, and the upper plate 9 rides on two bottom brackets 6 on helicopter,
The lower plate 10 is string configuration, lower plate 10 altogether there are two, two lower plates 10 are located at two bottom brackets 6
Lower section, two lower plates 10 are bolted respectively on upper plate 9, and upper plate 9 and lower plate 10 are by two bottom brackets 6
It is clipped in the middle for upper plate 9 to be fixed on helicopter, the hoist engine is fixedly mounted on the upside of upper plate 9, and described hangs
Rope 14 is the lift rope of hoist engine.The effect of upper plate 9 is installation hoist engine, and the effect of lower plate makes helicopter land position
Shape is held essentially constant, to will not influence the landing of helicopter.
Gondola ontology, structure include 2, two rollovers plate 3, kickboard 4, upper cover 5 and soft liners 12 of square groove.Square groove 2, two
Rollover plate 3 and upper cover 5 together constitute the rigid frame of gondola ontology, and soft liner 12, which constitutes one, prevents extinguishing chemical 13 from leaking out
Accommodating chamber.
The square groove 2 is rectangle structure, and four stiles height of square groove 2 is identical, two rollover plates 3 difference
It is hinged on two relatively narrow stiles of square groove 2, the soft liner 12 is the rectangular parallelepiped structure of top opening, soft liner 12
Bottom is fixedly connected on the inner wall of square groove 2, and two lesser facades of soft liner 12 lean against two rollover plates 3 respectively
On, the kickboard 4 is made of the light material that density is less than extinguishing chemical 13, and kickboard 4 is material of rectangular channel structure, kickboard 4
Four sides and four facades of the soft liner 12 match, and kickboard 4 is parallel to the slot bottom of square groove 2, and the upper cover 5 is also length
Square plate structure, four sides of upper cover 5 also match with four facades of soft liner 12, and the upper side edge of the rollover plate 3 is equipped with
The bending part 11 to bend inwards, bending part 11 hook upper cover 5 to prevent upper cover 5 from deviating from between two rollover plates 3, upper cover
5 upside is fixed with lifting lug, and the lower end of the lifting rope 14 is connected on the lifting lug.
Before use, gondola ontology be folded state as shown in Figure 3, in order to store and transport, need in use, using
Upper cover 5 is lifted up by hoisting apparatus (including helicopter), and rollover plate 3 is under the contact action of upper cover 5 during upper cover 5 lifts
It flips outward to vertical position (extreme position that vertical position is rollover plate 3) as shown in Figures 1 and 2, at this point, by being arranged
13 inlet of extinguishing chemical (this is conventional arrangement, is not shown in the figure) in 2 side of square groove injects extinguishing chemical 13, and kickboard is in extinguishing chemical
Float under the action of 13.
Different from tubbiness gondola ontology in the prior art, present invention employs the cuboid of length direction in the horizontal direction
Gondola ontology when helicopter transport, gondola ontology is above mentioned and is against it on bottom bracket of helicopter 6, can avoid transport
Gondola ontology shakes in the process, to effectively increase the flight stability of helicopter.In addition, the present invention passes through in gondola ontology
Interior setting kickboard 4 can effectively contain the flowing of extinguishing chemical during helicopter transport, avoid and generate because of extinguishing chemical flowing
Gondola ontology gravity center shift reduce the technical requirements to pilot to eliminate security risk in-flight.
The hinged place of the rollover plate 3 and square groove 2 is provided with torsionspring, work of two rollover plates 3 in torsionspring
With the lower movement tendency for keeping turning inside out to square groove 2, after use, upper cover 5 drops in the square groove 2, rollover
Plate 3 under the action of torsionspring automatic turning to location status as shown in Figure 3.
The downside of the square groove 2 is provided with idler wheel 1, the movement convenient for gondola ontology on ground.
There are three the hoist engine is total, one of them lifting for being used to gondola ontology provides power, referred to as main
Hoist engine 8, remaining two are the referred to as secondary hoist engines 7 for preventing gondola ontology from shaking, the lifting rope 14 on main winch 8
It is connected on the main lifting lug 15 of 5 centre of upper cover, respectively draws two lifting ropes moved synchronously on each of described pair hoist engine 7
14, four lifting ropes drawn on two secondary hoist engines 7 are connect with the secondary lifting lug 16 being distributed in around main lifting lug 15 respectively.
The top of the rollover plate 3 is provided with pressure sensor, after the top edge for plate 3 of turning on one's side is against in lower plate 10,
Pressure sensor senses are considered as gondola ontology at this time to pressure to reach upper limit position, the enhancing action of three hoist engines is equal
Stop and locks.
The kickboard 4 is made of rigid foam or plank is made, naturally it is also possible to compound using other lightweights
Material, as long as guaranteeing that kickboard can float on 13 surface of extinguishing chemical and have some strength.
The soft liner 12 is made of kiss-coating canvas, and the kiss-coating thickness of canvas is not less than 2mm, and enough kiss-coatings are thick
Degree advantageously ensures that the planarization of soft 12 inner wall of liner, to keep kickboard 4 more smooth in the intrinsic floating of gondola, while as far as possible
Reduce the gap between kickboard and 12 inner wall of soft liner.
