Background

The existing rodless aircraft tractor is widely applied to the field of various land airports. However, as more and more offshore platforms are equipped with flight equipment such as helicopters, the aircraft tractor has already been applied to the aircraft support of large ships. Different from the land, the large ship is an unstable platform and has a large amount of irregular swinging all the time. The swing generated by sea waves and the swing generated by the self maneuvering of the platform are difficult to predict. During the operation of a traditional tractor, the ground grabbing force is generated only by the gravity of the tractor, and when the tractor swings, the tractor can roll over, slide, run difficultly and the like due to insufficient ground grabbing force, and even can damage an airplane in severe cases. Therefore, a new tractor is needed to cope with the marine towing work.

Example 1:

the anti-swing aircraft tractor for the large ship as shown in the attached figure 1-2 comprises a tractor body 1, a swing measuring device 2 is arranged on the tractor body 1, an electromagnetic adsorption device 3 is arranged on the side of the tractor body 1, the electromagnetic adsorption device 3 comprises an installation frame 301, a spring 302, a movable column 303, a locking pin 304 and a locking spring 305, the installation frame 301 is arranged on the side of the tractor body 1, the movable column 303 is arranged on the installation frame 301 in a penetrating way, the spring 302 is arranged on the outer surface of the movable column 303, a support frame is arranged on one side of the top of the installation frame 301, the locking pin 304 is arranged on the support frame in a penetrating way, the locking spring 305 is arranged on the outer surface of the locking pin 304, an electromagnet is arranged inside the movable column 303, the tractor body 1 is a traditional rodless aircraft tractor, the swing measuring device 2 is arranged inside and is fixedly connected with the tractor body 1, when the tractor body 1 swings, the relative position between the two is not changed, and the swing measuring device 2 can measure the swing condition of the tractor 1 along with the large ship in real time; the electromagnetic adsorption device 3 is arranged on the outer side of the tractor 1 and is connected with the structure strengthening part of the tractor body 1; the control system inside the tractor body 1 is respectively transmitted with the electric signal and the control signal of the swing measuring device and the electromagnetic adsorption device.

The outer surface of the inner part of the mounting frame 301 of the movable column 303 is provided with a spring 302, the spring 302 can reset a locking pin 304 of the movable column 303 when the electromagnet does not work and is arranged on the inner part of the support frame, a locking spring 305 is arranged between the support frame and the limiting column, and the locking pin 304 can penetrate through a pin hole at the tail end of the movable column 303 under the action of the locking spring 305 to lock the movable column 303.

The tractor body 1 is symmetrical all around to be provided with electromagnetic adsorption device 3, and electromagnetic adsorption device 3 sets up four groups.

The control system is arranged in the tractor body 1, the control system, the swing measuring device 2 and the electromagnet are electrically connected, the swing measuring device 2 measures the swing state of the tractor body 1 in real time, the swing state of the tractor body 1 is fed back to the control system of the tractor body 1, the control system of the tractor body 1 sends a control signal to the electromagnetic adsorption device 3 after calculation, and after the electromagnetic adsorption device 3 receives the signal, the electromagnet in the movable column 303 works to generate an adsorption magnetic field, so that the adsorption force is generated on a deck, and the purpose of increasing the ground gripping force of the tractor is achieved; if the control system in the tractor body 1 has no signal sending function and calculation function, the control signal sending function and the calculation function can be integrally carried out on the swing measuring device 2, and the tractor body 1 only needs to supply power to the electromagnetic adsorption device 3.

The working process of the invention is as follows: the working principle of the anti-swing type aircraft tractor is as follows:

when large vessel sways, sway measuring device 2 and measure the state of swaying of tractor body 1 in real time, with the control system of tractor body 1's the state of swaying feedback to tractor body 1, the control system of tractor body 1 is through calculating the back, sends control signal to electromagnetic adsorption device 3, electromagnetic adsorption device 3 receives the signal after, the inside electro-magnet work of activity post 303 produces the adsorption magnetic field, thereby produce the adsorption affinity to the deck, reach the purpose that increases the tractor and grab the land fertility. If the control system in the tractor body 1 has no signal sending function and calculation function, the control signal sending function and the calculation function can be integrated in the swing measuring device 2, and the tractor body 1 only needs to supply power to the electromagnetic adsorption device 3.

The working principle of the electromagnetic adsorption device is as follows:

when the electromagnetic adsorption device 3 does not work, the movable column 303 is at the highest position under the action of the spring 302 and has a certain distance with the deck surface. When slightly swaying, the electromagnet inside the movable column 303 is electrified to generate smaller deck adsorption force, and under the adsorption force, force except gravity is added between the tractor body 1 and the deck, so that the ground grabbing force is increased. When the ship swings enough, even the airplane and the tractor turn over and slide, the electromagnetic adsorption force is increased, so that the tail end of the movable column is in contact with a deck, at the moment, the locking pin 304 of the electromagnetic adsorption device 3 penetrates through the pin hole at the tail end of the movable column 303 under the action of the locking spring 305, the movable column 303 is locked, at the moment, the tractor 1 does not run, the electromagnetic adsorption device 3 is firmly adsorbed on the deck surface, the tractor body 1, the electromagnetic adsorption device 3 and the deck surface are rigid whole, and when the ship swings, the side turning and the sliding cannot be caused by shaking. When the swing condition is reduced, the locking pin 304 in the pin hole at the tail end of the movable column 303 is manually pulled out for unlocking, the movable column 303 leaves the deck surface under the action of the spring 302, and the tractor can normally run.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
