SU1495171A1 - Device for stabilizing bulky cargo carried by aircraft - Google Patents

Abstract

The invention can be used for transporting bulk structures by aircraft. In the device, the housing is made in the form of two rings 5 and 6, equipped with a clamp, rollers and eyelets attached to the cables 8 through damping devices. During transportation of the load, the yaw moment is extinguished by the stabilizer 2. The stabilizer is brought to a working state manually. The proposed device helps to increase the speed of the helicopter, as well as flight safety. 6 Il.

The invention relates to devices used during transportation, and can be used to transport bulk building structures or building modular units by aircraft.

The purpose of the invention is to increase the efficiency of stabilizing the position of the bulk cargo during transportation by eliminating the transfer of the yaw moment of the volume load to the stabilizer and simplifying the design.

FIG. I shows the device, a general view; in fig. 2 shows a section A -A in FIG. one; in fig. 3 - section B - B in FIG. I; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - section G - G in FIG. 2; in fig. 6 - section D D in FIG. four.

The device for stabilizing the load comprises a rod I, at one end a carrier stabilizer 2; rod 1 is a tubular beam having stops 3 and 4 strokes moving in rings 5 and 6 by pulling cables 7 and 8, cable 7 passing through rollers 9 and 10, is connected at one end with ring 5 through a spring-loaded lever 11, which transmits the force to the retainer 12, fixing the position of the rod 1 relative to the ring 5. The spring 13 presses the retainer 12 to the body 14 in the extreme right position. On the ring 5 there are three rollers: the guide upper 15 and the lower supporting 16 and 17. The upper guide roller has a groove in which the guide bar 18 is placed, fastening on the rod I.

The cable 8 is fastened at one end to the stop 19 and passes through the roller 20, which is located on the collar 6, which in turn has three rollers: a guide 21 and a lower support 22 and 23.

Rings 5 and 6 are hung on the cable suspension 24 with the help of t 25 and 26 and damping devices 27 and 28. The damping device consists of the body 29 of the washer 30 of the spring 31. Moreover, the spring is in a prestressed state. The housing 29 has two openings: in one, a ha 2 passes, which is fixed without a gap by a nut 32, and a cable 24 passes through the other, which in turn is fixed by a gasket and a locknut screw.

The device works as follows.

After connecting the load to the hook of the cable suspension bracket 24, the rod 1 is pushed to its extreme position from the initial position so that the stabilizer 2 is at the maximum distance from the cable suspension bracket 24. Extension occurs as follows. During the tension of the cable 7, the tension force is not relieved through the roller 9 and 10 onto the spring-loaded lever 11, which in turn disengages from engagement with the rod 1 the clamp 12, after which the unlocked rod 12 freely moves along the rollers 15, 17, 21-23 The rollers 15 and 21 prevent the rotation of the rod 1 around its axis by means of the guide bar 18.

During the transportation of the load, the yaw moment is damped by the stabilizer and the force is transmitted through the center of the thigh, 1 ti 25 and 26 and damping devices 27 and 28.

Before disconnecting the load, the rod 1 returns to its original position due to the tension of the cable 8, which transmits the tension through the roller 20 to the support 19 fixed on the n tanga 1.
