Definitions

  • the object of the invention is a transfer device that grips wheels, and which intended to move an aircraft or device equipped with wheels over a base, which transfer device includes a frame, its own support wheels, a pair of rollers, devices to compress the rollers, and devices to rotate at least one of the rollers, locating devices to locate the rollers in a sideways direction in front and behind the wheel of the device to be moved, and in which by rotating the rollers pressed against one or both wheels the wheel of the device to be moved is made to rotate and.the entire device is made to move.
  • the construction of the transfer device can be substantially reduced when the rotating force is transferred to the airc ⁇ raft's own wheel from the drive wheel or friction roller of the transfer device.
  • the construction of a light transfer device that is universally applicable is shown in the Finnish Patent Application FI 833275 (partly corresponding to W085/01265) . This requires no contact with the bogie of the aircraft in order to compress the drive wheel against the aircraft wheel. The compression is achieved by means of the mutual adjustment of compression rollers that are placed round the aircraft wheel and which are connected by intermediate devices.
  • the main principle of the invention is that the longitudinal movement of the rollers is carried out by means of an intermediate arm.
  • the turning of this intermediate arm also causes a lateral movement in the roller, but this lateral movement can be either arranged to be so small as to be of no significance or it can be compensated for by means of a genuine lateral movement.
  • the transfer device shown in Patent Claim 5 has a separate lateral roller movement, in which case the longitudinal movement of the roller can be carried out by means of two intermediate arms, which together form a parallelogram or other quadrilateral.
  • a construction of this kind withstands greater stresses than the former and is better suited to high-powered transfer devices.
  • Figure 1 shows the transfer device seen from above in partial cross-section
  • Figure 2 shows the transfer device seen from the side
  • Figure 3 shows the control mechanism of the interme ⁇ diate arm in detail
  • Figure 4 shows another transfer device seen from above
  • Figure 5 shows a third joint arrangement
  • Figure 6 shows the joint arrangement of Figure 5 wit the roller in the fully open position
  • Figure 7 shows the joint arrangement seen from the direction A in Figure 5
  • the transfer devices shown in Figures 1-3 are intended for the movement of aircraft on an airfield.
  • the aircraft 1 is represented by only the landing-gear vogie and wheels 6.
  • the transfer device travels to the aircraft driven by its rear support wheel 13, and in addition to this its princi ⁇ pal components are friction rollers 3 and 4, devices to compress and rotate them, a power device unit, and frame components 5 and 2.
  • the transfer device which has a U-shaped frame, is driven round the double wheel of the aircraft with the front rollers 3 retracted to the side.
  • the U-shaped frame is formed by a rear section 5 and forks 2.
  • the rear section 5 of the frame includes a diesel motor as a power source and a hydraulic pump driven by it.
  • the rear section 5 includes control devices, a fuel tank, and hydraulic auxilliary devices.
  • Figure 3 shows a mechanism, by means of which roller 3 is made to move through a limited area in one direction.
  • the mechanism utilizes the operating device 9 of the intermediate arm in such a way that the arrangement attempts to keep the joint points of levers 14 and 15 in a parallelogram.
  • the support 7 of the roller is attached to the first lever 14 which operates the operating lever 15 by means of the arm 16 and in turn this operates the three-way hydraulic valve 17.
  • This hydraulic valve 17 keeps both ends of the operating device 9 closed, if the lever is in the central position, and feeds oil to that end of the cylinder which tries to correct a change in the angle of the roller support.
  • the transfer device travels on its own support wheels 12 and 13.
  • the front support wheels 12 of these turn freely and the rear support wheel 13 has both control and rotation connected to it to allow the movement of the transfer device itself.
  • the rear support wheel too turns freely while moving an aircraft.
  • the basic construction of the transfer device shown in Figure 4 is of the same type as that shown in Finnish Patent Application 881057.
  • the lateral movement of the rollers takes place by moving the forks laterally using parallelogram arms 19.
  • the rear section 29 of the frame has the fork sections 20 connected to it by means of the parallelogram arms 19.
  • the front roller 23 and its operating motor 26 are rigidly attached to the fork section 20.
  • the support 22 of the rear roller 24 is attached to the terminal arm 22 jointed to parallelogram arm 21.
  • Fork section 20 is princiaplly formed of pipe section. An opening corresponding to the lateral movement is made in it for the axle of roller 24.
  • Both its motor 25 and the hydraulic cylinder 30 operating the parallelogram are located inside the pipe of the fork section 20.
  • rollers 23 and 24 take place in the same way as in the transfer device in accordance with Patent Application FI881057.
  • the wheel 27 is raised, in which case the fork sections drop onto the front wheel 28.
  • the parallelogram arm 19 can then be used.
  • wheel 27 is lowered and means of it the fork section 20 is raised and by using the parallelogram arms 21 rollers 23 and 24 can be pressed against the wheel of the aircraft and the rotation of the rollers can be commenced.
  • the curve of the initial section corresponds to the operation of the parallelogram arm, in which case roller 3 moves in one directi ⁇ on in the track of wheel 6.
  • the control roller moves to the final section 33 of the guide 32, which forces the roller 3 to turn away from the track of wheel 6. It is extremely advantageous that roller 3 turns round against the counter member 35 of the turning front wheel and locks it into a straight forward direction. Due to the compressive force directed onto the roller the intermediate arm 8 is made as sturdy as possible, Figure 7. No moment at all is transferred through the control roller 30 to the guide 32.

Abstract

L'invention concerne un dispositif de transfert avec prise sur roues, conçu pour déplacer un avion (1) ou un autre appareil à roues sur une base, comprenant une structure (5, 2), ses propres roues de support (12, 13), une paire de rouleaux (3, 4), des dispositifs comprimant les rouleaux ainsi que des dispositifs destinés à mettre en rotation au moins un des rouleaux (4), des dispositifs de positionnement destinés à placer les rouleaux à partir de leur position latérale devant et derrière la roue (6) de l'appareil (1) à déplacer, et dans lesquels par la mise en rotation des rouleaux (3, 4) comprimés contre la roue (6) de l'appareil à déplacer, celle-ci (6) est mise en rotation et tout l'appareil est mis en mouvement. Le but de l'invention est de produire un dispositif de transfert mettant en rotation la roue, dans lequel le mouvemet longitudinal des rouleaux dans un guide a été remplacé par un autre procédé. Selon l'invention un bras intermédiaire (8) est monté de manière articulée sur la structure (2), le support (7) du rouleau (3) étant monté de manière articulée sur son autre extrémité. On peut tourner ledit bras intermédiaire (8) entre deux positions extrêmes afin de déplacer le point d'articulation (11) du support (7) du rouleau (3) dans une courbe déterminée par ledit bras intermédiaire (8), ce qui permet de déplacer le rouleau (3) longitudinalement et de le comprimer contre la roue (6).
