Definitions

This lifting device is used for lifting and lowering operations, for leveling purpose, for self-leveling and weighing of: aircrafts, such as aeroplanes, helicopters, civil and military aircrafts, watercraft, camping vehicles and similar, cars and trains, bridges, radar, and any other structure and/or object to which it can be applied.
aircrafts such as aeroplanes, helicopters, civil and military aircrafts, watercraft, camping vehicles and similar
cars and trains such as bridges, radar, and any other structure and/or object to which it can be applied.
the procedure of lifting is made in the following way: are used for operation of weighing, balancing, maintenance and leveling, hydraulic jacks or self assisted for lifting, activated by manual methods.
This manual operation is obtained by a minimum of five operators which proceed to this lifting operation with much time of actuation: moreover, could be possible a structural yielding of the hydraulic jack during the operation of lifting and this may be cause of damages to persons and things.
This Self-Leveling Integrated Lifting device brings the following improvements:
this lifting group works everyone autonomous or in synchronous speed to have a self-leveling operation to reference to a leveling cell (Fig. 05).
This Self Leveling Integrated Lifting device in order to avoid that one of the jacks for effect of instability to the ground doesn't guarantee one perfect adherence, ( as an example during the operations of lifting may happens a separation from the linking points scheduled on the aircrafts and helicopters, etc..), it assure the raising and therefore it allows a perfect weighing and leveling to balance the weight; it is completely automatic only when the linking points scheduled by the aircraft are perfectly adherent to the ground and its linking points;
the benefits of this innovation are: fully electronic management and at distance, only with an operator who with this device operate by few time for the lifting and lowering; to allow the lifting in emergency situations in which is indispensable in few time to supply the apparatus and balance the weight upon the aircraft before the takeoff; reduced maintenance and easy use owned to the considerable mobility of the lifting groups; high safety owned by the use of "nut-screw" penetrable, self-blocking, which at the end of the lifting operation, it avoid possible instabilities of the attitutude obtained upon the aircraft, besides accidental lowering
an absolutely new feature is representated by the fact that lifting and, therefore, lowering can be obtained in synchronism, with a special floating head for centring operation in case of application to large-dimension aircraft.
Another feature is the display of partial and total weights and leveling measurement, this latter being possibly obtained acoustically as well.
Self-leveling is also useful to operate on mobile surfaces, such as floating platforms, aircraft carriers, etc. In the specific case of various camping vehicles, perfect internal attitude is required for electrical appliances (refrigerators, etc.) and for people inside, independent of the ground the vehicle rests on.
the benefits of the Self-leveling Integrated Lifting device include shorter time for automatic application, with the above-reported characteristics but different capability of resistance to loads in lifting and lowering, in addition to synchronous, automatic lifting of one or more lifting groups, which avoids possible damage to the structure or users.
the Self-leveling Integrated Lifting device also allows to reduce time losses and overwork for operation and is perfectly safe for the stability of the lifters used by an operator alone.
the lifting device is made of three or more groups of ELECTRO-MECHANICAL LIFTERS (Fig. 01 and 04), a CENTRAL GENERAL CONTROL (Fig. 12), and a LEVELING CELL (Fig. 05).
Each ELECTROMECHANICAL LIFTER (Fig. 01) is constituted by the following elements: a load-bearing base and some supports (Fig. 01, particular 6) equipped with moving wheels (Fig. 01, particular 4), each including the following parts: a jack with "nut-screw system", i.e. bronze-threaded, penetrating, telescopic screws and bushings with one or more sectors (Fig. 1, particular 1), two accumulators (Fig. 01, particular 9), a battery charger (Fig.
Every lifting group is self-functioning, being integrated with an electronic card apparatus (Fig. 01, particular 10) that can be operated at various degrees of speed or in multiple, for control function in synchronism of every lifting group, with automatic weight control that follows lifting by controlled push of the load.
This synchronous control function allows to perform lifting and lowering operations.
the lifting system is also provided with an automatic sensor to avoid possible structural damage of the aircraft, also aimed at overcoming difficulties in transport of the lifting system itself.
This self-adhesion automatic sensor is necessary for multiple control during the synchronous function, and provides perfect lifting and weighing just as all points expected to link to the vehicle are presently and perfecly attached with the liking points, so that any detachment is avoided.
the lifting group is equipped with a tripod base, with the specific shape and structure as shown in Fig.
the self-centring floating head (Fig. 11) for the specific lifting device at the rear of the aircraft functions as an automatic control (self-controlled version) of the rear shift, by never exceeding the safety load limits given in the aircraft specifications aflter proper calibration.
the following actions take place: two main lifting devices together with the rear lifting group (Fig. 10) start the aircraft detachment from ground.
This rear lifting group possesses an automatic weighing system that follows lifting with a controlled-load push. If the load is exceeding or insufficient for aircraft attitude, as provided for in the aircraft specifications, a load cell - suitably calibrated according to load requirements - stops automatically the whole lifting system by displaying the excess or defect load (safety threshold). After recovering regular attitude, the operation may bee repeated.
These lifting and lowering operations can be performed by a single operation outside the aircraft, who uses a palmar remote control in perfect safety, rapidly and with little energy, thanks to the easy handling of the device (Fig. 10, particulars 6 and 4).
the CENTRAL GENERAL CONTROL (Fig. 12) is composed of a remote control for self-leveling and manual operations (Fig. 12, particular 4) plus a system with electrical command card for self-leveling, linked with the lifting groups (Fig. 12, particular 1) by means of wires or radio control.
the central general control (Fig. 12) is aimed at receiving and processing signals coming from the leveling cell (Fig. 05) through wires linked with the IN-connector of the level (Fig. 12, part. 2). As soon as received, the signals are co-ordinated by the electrical command card.
a series of accumulators (Fig. 01, part.
this card supplies the energy necessary for the lifters to start and drives them to their self-leveling operation, either in synchronism or singularly.
the whole apparatus is enclosed in a portable metal case that allows the user to control and operate the different lifting groups by means of a keyboard (Fig. 12).
the LEVELING CELL (Fig. 05) is an integrated, compact, airtight device with fluid-controlled oscillation that represents constant reference for the whole system, placed within the aircraft by means of a telescopic sustaining pole (Fig. 07), directly linked with the central general control (Fig. 12) or with the electronic command apparatus (Fig. 01, part. 10) through electric multipolar wire. It is made of the following components: a mechanical pendulum (Fig. 05, sect. C, part. 2) placed on a suitable, highly sensitive, wedge pin (Fig. 05, sect. B, part. 1) enclosed in an airtight methacrylate cell (Fig. 5, sect. B, part. 2), submerged in antifreeze fluid for antishock effect.
the leveling cell is enclosed in a suitable container (Fig. 06) together with the following components: external reading sensors (Fig. 05, sect. B, part. 4 - description of mortise positioning of the sensor inside the container Fig. 06), with infrared, photoelectric, or similar power of interception of the mechanical pendulum shifts (Fig. 05), LED for sensor interception and sensitivity regulators for leveling calibration.
the leveling cell is equipped with supports appropriate for every kind of means to be lifted and self-levelled.
Fig. 07 shows a sustaining telescopic pole with a spherical sector that operates in reference to the leveling cell (Fig. 05) whose container (Fig.
goniometric support (Figs. 08 and 09) is part of the Self-leveling Integrated Lifting device and acts by means of an electronic control device for triangulation, which makes easier the shifting of the longitudinal axis for targeting purposes or aircraft attitude simulation. This goniometric support (Figs.
a knob (Fig. 08, part. 05; Fig. 09, part. 1) placed at the basis of the graduated goniometre to perform manual simulation maneuvers.
the leveling cell (Fig. 05) is placed inside the aircraft by means of its support telescopic pole (Fig. 07) and connected through multipolar electric wire to either the electronic command apparatus including an electronic card (Fig. 01, part. 10) placed inside each lifting group (Fig. 01) for autonomous function, or the IN-connector of the level in the central general control (Fig. 12, part. 2) also provided with electric command card for function in synchronism of the various lifting groups.
Every shift of the mechanical pendulum in the level cell is translated by the external reading sensors into electrical impulses, which in turn are sent to the electronic command system or central general control (Fig. 01, part. 10) through wires and therefore translated into shifts by the electronic card for signal control that interprets them as lifting and/or lowering and moves the lifters.
