JPH1076997A - Air conveyance container - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve safety and to increase a flying speed at the return route of a helicopter by a method wherein air is prevented from entering into an empty bag, deformation of the bag is regulated to a shape where air resistance is reduced, and the bag is floated up and wound around and makes contact with the helicompter. SOLUTION: An air conveyance container is formed such that a fluid material is placed in a bag and suspended from a helicopter through a suspension string tied to a suspension washer. In this case, a skirt 12 to shield an opening part 5 is attached to the outside of the opening part 5 arranged between the bag 1 and a head washer 4. A press member 20 to press a part of the bag when the bag 1 is brought into an empty state and regulate the deformation mode of the bag 1 is arranged in the rear in the advancing direction of the bag 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for containing a fluid substance and transporting it in the air by helicopter or the like.

[0002]

2. Description of the Related Art An aerial transport container in which a fluid substance is put in a bag and is transported by suspending it to a helicopter or the like by a suspension cord connected to a head washer is known from Japanese Patent Publication No. 52-21319.

[0003]

However, this aerial transport container has an opening for injecting a flowable substance between the bag and the head washer, and this opening discharges the substance to allow the bag to be discharged. On the return route where the air becomes empty, the air bag inclines so that the opening faces forward due to the air resistance. There is a danger of winding or touching. For this reason, there is a problem that the flight speed of the helicopter cannot be increased, and the return path of the empty load drops and the flight time becomes longer than that of the actual load.

[0004] The present invention solves the above-mentioned problems, prevents air from entering into an empty bag, restricts the shape of the bag so as to reduce air resistance, and wraps or touches the bag around a helicopter or the like. It is an object of the present invention to provide an aerial transport container that can prevent the flight speed of a helicopter or the like and reduce a decrease in the flight speed on the return route.

[0005]

As a means for solving the above-mentioned problems, an aerial transport container according to the present invention comprises a bag in which a fluid substance is put into a bag, and a suspension cord connected to a head washer is used for a helicopter or the like. In an aerial transport container that is suspended and transported, a shielding skirt of the opening is attached to the outside of the opening existing between the bag and the head washer, and when the bag is emptied rearward in the traveling direction of the bag, a part of the skirt is removed. It is characterized in that a configuration is provided in which a pressing member that presses inward to regulate the deformation of the bag is provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of an aerial transport container according to the present invention.

In FIGS. 1, 3 to 5, reference numeral 1 denotes a bag, and a material obtained by bonding a double-sided tarpaulin of vinyl chloride to a 66 nylon base fabric by welding is provided with openings on the upper and lower sides. It is formed in the shape of a water drop, and three or more hanging members 2 are attached to the upper opening, and the upper ends of these hanging members 2 are suspended by a suspension string 3 into a head washer 4 which is suspended by a helicopter (not shown). Head washer 4 and bag 1
The upper end of the bag is fixed so that there is an opening 5 for putting the flowable substance into the bag 1, and the lower opening of the bag 1 is watertight to a valve seat housing 7 having a valve 6 which is opened and closed by an electric signal. The valve seat housing 7 and the head washer 4 are connected to each other by three or more wire ropes 8 in the bag 1 so as to bear the load on the wire ropes 8 and the head is located at the center of the bag 1. An extendable shaft 9 that connects the washer 4 and the valve housing 7 is disposed, and the bag 1 is held upright by the shaft 9.

The base fabric constituting the bag 1 is not limited to nylon 66, but may be synthetic fibers such as nylon 6, polyester, and vinylon. Also,
The vinyl chloride bonded to both sides of the base cloth is not limited to this, and any resin that can be welded may be used. 1, 4 and 5, reference numeral 10 denotes a base wheel for stably placing the bag 1 on the ground or the like, and is formed in an annular shape having a size corresponding to the maximum diameter of the bag 1, A directional stabilizing plate 11 for stabilizing the direction of the bag 1 is provided on a portion of the base wheel 10 which is rearward in the traveling direction when the bag 1 is transported. It is provided so that it can be defeated when not needed.

In FIG. 1 to FIG.
And a skirt for closing the opening 5 present between the head washer 4 and the same material as the bag 1, the upper end of which has a diameter adapted to the step 4a of the head washer 4, and the lower end has fluidity. When a substance is put in, it is formed into a frusto-conical shape with a diameter adapted to the outer circumference of the bag 1, and a part thereof is cut open in the vertical direction and joined with the slide fastener 13 as shown in FIG. Can be expanded. The skirt 12 has a rope 1 at the upper end as shown in a partially enlarged view of FIG.
3 is wrapped and the lower side thereof is pressed by a pressing band 16 into an annular groove 15 provided in a step 4a of the head washer 4 as shown in a partially enlarged view of FIG.
These stoppers 17 are folded back through a receiving ring 18 attached to the bag 1, and the overlapping portions thereof are joined by a hook-and-loop fastener 19 so that the opening 5 can be reliably closed by the skirt 12.

In FIGS. 1, 4 and 5, reference numeral 20 denotes a pressing member for the bag 1 provided in the rearward direction of the bag 1, that is, in the direction in which the directional stabilizer 11 is attached to the base wheel 10. When the bag 1 is emptied, the rear portion in the traveling direction is pressed inward as shown in FIGS. 4 and 5, thereby restricting the deformation of the bag 1 so that the air resistance becomes small. When the bag 1 is inflated to contain a flowable substance, the amount of articles contained in the bag 1 is reduced if the bag 1 is not expanded. It is preferable to be able to follow the deformation.

In the above-described embodiment of the present invention, a fluid substance is put into the bag 1 through the opening 5, the opening 5 is closed by the attachment of the skirt 12, and the rear of the bag 1 in the traveling direction is pressed. When the bag 1 is held down and carried by a helicopter or the like and transported, the bag 1 is emptied and the bag 1 is emptied and returned when the bag 1 is emptied and returned. Even if the skirt 12 is inclined, the skirt 12 closes the opening 5 and does not allow air to enter the bag 1.
Since 0 presses a part of the bag 1 inward, the bag 1 is deformed into a shape having less air resistance as shown in FIG. And
In the state shown in FIG. 4, the bag 1 is prevented from rising to the upper rear part in the traveling direction to some extent, and the rising angle of the bag 1 is reduced, so that the bag 1 can be prevented from wrapping around or touching the helicopter or the like. Nature,
As a result, the flight speed can be increased.

As described above, the aerial transport container according to the present invention closes the opening of the bag with the skirt to prevent air from entering the empty bag, and presses the bag in the direction of travel by the pressing member. Since the bag is deformed into a shape with low air resistance, the air resistance acting on the bag prevents the bag from being lifted up and wrapped around or touching a helicopter, etc., thereby increasing safety and increasing flight speed. On the other hand, a return flight of an empty load, which conventionally required a longer time than the forward movement of the actual load, can be performed in less than half the time of the forward movement.
