Description

The invention relates to hoisting and transport machinery, in particular to devices for mounting structures using aircraft.

A device for mounting structures by an aircraft is known, comprising a suspension bracket with a traverse connected by two flexible couplings, on which a fixing device with disks is fixed in the center, on which a stabilizing rod with a clamp is fixed, the free end of which is attached by two flexible couplings to the helicopter body. RU No. 1693217, IPC E04H 12/34.

The disadvantage of this device is the following. If emergency dumping of cargo from the helicopter’s external suspension is necessary, breaking flexible connections requires considerable efforts on the rear nodes of the aircraft, which creates difficulties for piloting the helicopter and, therefore, safety; and also in connection with the design features of various aircraft, not all have nodes for fastening the flexible links of the stabilizing thrust.

The tasks to which the proposed solution is directed are to increase the level of safety during the installation of structures and unification of the device.

The technical result is achieved in that the mounting device having a suspension, a traverse, a fixing device and stabilizing traction, while on flexible connections or rigid mounts rigidly or pivotally connected to the aircraft body, there is a stabilizing device made in the form of a double frame with two degrees of rotation - the outer frame rotates on hinges mounted on flexible connections or rigid mounts, rigidly or pivotally connected to the aircraft body, and stabilizing the internal I frame - on the hinge secured to the outer frame perpendicular to its axis, while the free end of the stabilizing rod lies on the internal stabilizer frame, adapted to slide freely relative to the internal stabilizer frame.

The drawings show a device for mounting structures by an aircraft.

In FIG. 1 - general view.

Figure 4 - stabilizing device, pivotally connected to a rigid mount, pivotally connected to the body of the aircraft.

Figure 5 - stabilizing device made in the form of external and internal frames.

The device comprises an aircraft 1, a traverse 2, mounted on suspension ropes 3 with hooks 4, a fixing disk 5 with holes for a retainer, a stabilizing rod 6 with a retainer, a stabilizing mechanism consisting of external and internal stabilizing frames 7 and 8, respectively, interconnected axial hinges 9, on the outer frame axial hinges 10 with nodes for attaching the outer frame to the aircraft 1 using flexible connections 11 or rigid mounts 12, rigidly or pivotally connected to the aircraft body 1. Suspension 3 to the aircraft body 1 is fastened by the electric lock 13. The design of assembly 14 is suspended on the ropes via hooks 4. Rigid attachment 12 may be configured to slip relative to the housing and fixing of the aircraft 1 (FIG. 3).

The device operates as follows.

Under the helicopter 1, a suspension 3 with hooks 4 and a traverse 2 is mounted on an electric lock 13, on which a fixing disk 5 is rigidly fixed, then a stabilizing rod 6 with a latch is attached to the disk 5 using a hinge, the upper end of which leads to the inner the stabilizing frame 8, pivotally connected to the outer frame 7, mounted on the helicopter 1, using flexible connections 11 or rigid devices 12 through the hinge assemblies 10. By means of a latch on the fixing disk 5, a traverse 2 is positioned relative to the haulage rod 6 to the design position, which depends on the position of the mounted structure 14 on the object and the direction of the wind for the aircraft to hang 1. The aircraft 1 (helicopter) hangs over the structure 14, it is connected through hooks 4 and the suspension 3 with structure 14.

When hovering a helicopter 1 with a structure 14, the stabilizing rod 6 through frames 7 and 8, mounted on flexible links 11, is fixed relative to the aircraft in a certain position in the horizontal plane. Traverse 2, suspension 3 and structure 14, stabilizing rod 6 are also fixed relative to the aircraft 1 in a predetermined position in the horizontal plane, while the free end of the stabilizing rod 6 is located in the inner stabilizing frame 8.

In the event of an emergency requiring a reset of the structure 14, the pilot opens the electric lock 13 and the structure 14 begins to fall together with the suspension 3, the traverse 2 and the stabilizing rod 6, while the rod 6 freely, without jerking out of frame 8. It does not matter , in what position relative to the vertical axis of the aircraft 1 is the structure 14, since when the stabilizing rod 6 is turned behind the center of gravity of the structure 14, the frames 7 and 8, having two degrees of freedom of rotation, will be deployed behind the stabilizer axis conductive rod 6 and, consequently, in any position of the structure 14 about the vertical axis of the aircraft 1 freely rod 6 out of 8 internal stabilizer frame.
