[Detailed description of the invention] 歿igo9 names Transfer equipment for transport equipment Chivalry blood hill group FIELD OF THE INVENTION The present invention relates to a device for moving transport equipment, and more particularly to a transport device with wheels. The present invention relates to a device for moving a transport device from one position to another.

The present invention is particularly suitable for moving aircraft, but also for moving cars, trucks, etc. Also used for moving all types of transport equipment with wheels, such as rolling stock and railway cars. be able to. In the following, for convenience of explanation, the present invention will be specifically applied to the movement of aircraft. Let's talk about when to do this.

R plate 9 equal parts Generally, to move a transport device from one position to another, the transport device must be auxiliary traction, which may utilize its own propulsion means or be coupled to the transport device to be moved; It is necessary to use means.

Auxiliary traction devices for large aircraft, such as those used at international airports, are relatively expensive. Ru. The tow truck, which is such a towing device, is used to move the aircraft to or from the loading dock. Used to route paved surfaces such as airport runways for inspection, inspection, etc. There is. However, such towing vehicles are expensive, so if the towing vehicle is It may not be possible to use it, and there may be a delay in dealing with it.

Traction devices such as traction machines and tractors that use a prime mover have horizontal friction between the traction device and the ground. The force is the horizontal friction force and other acting forces that occur between the towed transportation device and the ground surface. Dogs may be allowed to tow transportation devices such as aircraft. this The traction force is calculated by the weight of the traction device, the force applied to its ground wheels, and the traction device wheels. and the coefficient of friction between the ground and the ground. For example, an airport runway is covered with water or ice. especially when the aircraft has been parked for some time and the tires are flat with the ground. If the aircraft is deformed so that it is in contact with It is extremely difficult, if not impossible, to develop traction.

Additionally, to use a ground tow vehicle at an airport, there are usually at least three people operating the tow vehicle. Hands and two watchmen are required, and in some cases, for example, the tow bar of a ground tow vehicle. Additional personnel may be required to assist in installing the wheels or unchocking the aircraft wheels. It takes. As long as this number of ground staff is required, the operating costs of the airport will rise. do.

At airports for light aircraft, light aircraft with their engines stopped are usually moved by hand. Protection During maintenance inspections, light aircraft are taken out of hangars to complete maintenance inspection standards. In addition, it is necessary to return other light aircraft from the maintenance hangar. The need to take things out and put them in occurs quite frequently. Furthermore, every time you move a light aircraft This requires personnel to do so, and it is necessary to attach the wing tips of the airplane to hangar structures and other structures. There is also a risk of damaging it if you touch it. In addition, a conventional towing vehicle can be run inside the hangar. This pollutes the air, so this is something we would like to avoid if possible.

FIG. 8 shows a shaped contact roller that is one feature of the present invention.

Kanshi five nine ri The one shown in FIGS. 1 and 2 is equipped with two sets of counter-rotating rollers 12/14 groups. This is a moving device for a transportation device, and each set of rollers is arranged alternately. The axes of the 12 groups of rollers and the axes of the 14 groups of rollers are arranged at least vertically. They are located a distance apart. The roller 12 is a ground roller that contacts the ground. On the other hand, the rollers 14 are supported upwardly off the ground, e.g. contact the surface of the tires 16 of the transportation device to be moved, such as the front tires of It is a contact roller.

The two sets of counter-rotating rollers 12/14 are arranged before and after the tire 16, respectively. There is. If necessary, use counter-rotating rollers to ensure that the tire 16 is exactly centered. Auxiliary guide rollers 17 are installed on both sides of the tires 16 to adjust the position of the 2/14 groups. It can also be provided separately.

The above two sets of rollers 12/14 are mounted on a support frame or an equivalent member. Each set of rollers 12/14 is moved to the position shown. so that it can be fixed in place. As an example of the support drive form for this purpose, one common An axle is inserted in communication with each of the roller groups 12/14, and, for example, a ground roller is connected to the common axle. A gear group is provided that directly meshes with each of the 12 groups of gears, and the rotational force of the axle is transferred to the contact wheels. A method of providing an intermediate gear group that transmits information to each of the 14 groups of gears and rotates them in opposite directions. There is a law.

In addition, as another support drive form, adjacent rollers are mutually supported by internal bevel gears. The rotational force applied to the roller 12 at one end is applied to the adjacent rollers 12 that are connected directly to each other. The roller 14 directly rotates in the opposite direction, and similarly, the roller 14 further rotates in the opposite direction. There is also a method of rotating the entire roller group of each set by rotating the rollers 12. Ru.

Furthermore, as another drive mode, the 12 groups of grounding rollers may be driven by hydraulic pressure or electric power. In addition to rotating in one direction, 14 groups of contact rollers are also driven by hydraulic pressure or electric power. There is also a way to rotate it in the opposite direction.

When the drive configuration is configured in this way, the rollers in each roller group are driven separately, and each Since they can be controlled separately, the rollers at one end of a set of rollers can be controlled more easily than the rollers at the other end. It is possible to rotate at high speeds, so that the rollers and tires 16 The direction of the can be changed.

For example, rotate the roller 12 group in the direction of arrow A in FIG. 1, and rotate the contact roller 14 group in the opposite direction. In other words, when rotating in the direction of arrow B, the right roller group will move to the left as shown in Figure 1. As a result, a press-contact co-rotating action occurs between the contact roller group 14 and the tire 16. This causes a downward force to act on the grounding rollers 12 group. The rotation of this 14 group of contact rollers The press-contact co-rotating action by rotation rotates the tire 16 in the direction of arrow C, and the vehicle of the transportation device rotates. The wheel and the transport device supported by it move in the direction of the arrow.

The left roller L2/14 group is connected to the right roller during the movement of the transport device to the left. It rotates at the same speed as the R group to help rotate the tires 16.

The rotation of the wheels or tires 16 of the transportation device is caused by applying a braking force to the left roller group. The rotational speed of the tire is lowered, and the tire is applied with greater force by each contact roller 14 in the left group. Braking can be achieved by bringing the tires 16 into contact with each other and causing a braking action on the tires 16. Ru.

In other embodiments of the invention, rollers 12/14 may be hydraulically or electrically powered. Acceleration and deceleration are caused by the tire 16 moving and flying over the brake side roller group. This is done by controlling the rotation speed so as not to exceed the limit. In addition, each of the above rollers and tires 16 It is understood that the dimensional ratio of the It should be possible. Therefore, if necessary, a feed that can detect the dynamic tendency of the tire 16 is provided. A guide roller is provided separately to prevent acceleration and reduction in order to prevent the above-mentioned problems. It can also be configured to automatically change the speed to an appropriate value.
