Abstract

FIELD: transport.

SUBSTANCE: proposed aircraft towing device comprises drive truck with rotary platform mounted thereon to revolve in horizontal plane. Aforesaid platform accommodates pneumatic-webbing jack with its lower part rigidly attached to the rotary platform, and its upper part accommodating the platform made up of two parts that represent the aircraft shape. Aforesaid parts are jointed together with the help power hydraulic cylinder to move in horizontal plane.

EFFECT: expanded range of towed aircraft, uniform load distribution over the drive truck frame.

Description

The invention relates to the field of ground handling of aircraft and, in particular, can be used in the development of aircraft towing devices.

A device for towing aircraft, driven by a tractor, on the frame of which is mounted a platform with the possibility of rotation in the horizontal plane and a lifting mechanism in the form of power hydraulic cylinders, is equipped with a pneumatic saddle cushion [patent RU 2191144 C2, 10.20.2002].

The disadvantages of this device are the impossibility of towing aircraft of various types, which limits the class of towed aircraft, as well as the uneven distribution of load on individual parts of the tractor frame.

The technical result is the expansion of the class of towed aircraft, as well as the uniform distribution of the load on the tractor frame. The specified technical result is achieved by the fact that a pneumatic tissue lift is installed on the rotary platform, which is rigidly fixed with the lower part on the rotary platform, and on the upper part there is a platform made of two parts in the form of an aircraft fuselage, which are interconnected by a power hydraulic cylinder and can move in a horizontal plane .

The invention is illustrated in figures 1 to 3.

Figure 1 and figure 2 shows a side view and front of a device for towing aircraft.

Figure 3 shows a top view of the platform located on the upper part of the pneumatic tissue lift.

A device for towing aircraft includes a tractor 1, a rotary platform 2, a pneumatic tissue lift 3, a platform 4, a hydraulic cylinder 5, a platform 6.

Pneumatic fabric lift 3 is designed for emergency lifting of aircraft by using flexible inflatable cylinders under pressure. It can be made, for example, of three or five cylinders interconnected.

Platform 4 is designed to capture the aircraft fuselage when towing it from the runway or the airfield of the airfield. It is made of two halves interconnected by a power hydraulic cylinder 5, which can be moved in a horizontal plane, which allows you to adjust the platform 4 for any type of aircraft fuselage.

The device operates as follows. The driver of the tractor 1 drives up to the aircraft so that the fuselage of the aircraft is located above the pneumatic tissue lift 3 mounted on the turntable 2 of the tractor. Thanks to the rotary platform, the tractor has the ability to approach the aircraft at any angle. After the device is in the desired position, the driver adjusts the platform 4, mounted on the platform 6, under the fuselage of this type of aircraft. Next, the driver, on command, pumps air into the cylinders of the pneumatic tissue lift. In this way, the fuselage is lifted, and the driver, upon command, tows the aircraft from the airfield of the airfield.

The present invention is industrially applicable, as for its implementation can be used components and assemblies used in the aviation industry.
