    DESCRIPTION REPORT OF THE PATENT FOR THE CARRIAGE FOR THE TRANSPORT OF AN AIRCRAFT ENGINE MODULE.
    Description [0001] The present invention relates to a cart for carrying an aircraft engine module.
    Transporting an aircraft engine module before it is assembled is often difficult as these modules are bulky, heavy, but delicate items, which must be placed in a precise position for docking with adjacent modules in order to assemble the engine. Additionally, some modules must be turned over before being installed, in order to verify that no foreign bodies have been introduced between the rotor and the stator and, therefore, do not damage the motor when it is operated.
    [0002] The traditional method for carrying out these operations consists of using a crane to place the module on a non-specific cart or on a forklift with wheels, moving the cart to the location where the engine is mounted, and once again lifting the module using a crane in order to turn it and moor it. These operations are laborious, difficult and tiring as substantial forces must occasionally be provided. There is the intervention of two people. The most delicate points are those when the module is deposited on the cart without impact, when the module is temporarily turned, and when it is docked with the module with which it will be assembled, when an accuracy of about two millimeters is required. The procedure is quite long.
    [0003] US-A-2,825,477 describes a cart for sharing an aircraft engine including a structure with wheels, two extendable vertical arms, and a support supported by axles
    Petition 870190121076, of 11/21/2019, p. 5/18
    2/7 transversal at the tops of the arms, where the motor can be installed and fixed, and that rotates around the transversal axes in such a way that it has variable inclination.
    [0004] The invention relates to a transport cart of a particular type, which is specially designed for aircraft engine modules, and which is also designed to facilitate its movement between an original location, which can be a work where it was prepared, and an assembly site for the adjacent modules. It satisfies a particular restriction that you must temporarily tilt the module to check its conditions.
    [0005] In general, it refers to a cart for the transport of an aircraft engine module, including, firstly, a wheeled structure and a reinforcement structure for receiving the model installed in the structure, characterized by fact that the reinforcement structure includes two module receiving structures positioned on the two side sides of the cart, where each receiving structure includes a vertically movable arm, a support at an upper end of the arm, where the support rotates around a transverse axis of the trolley, a module support extension, which moves the support in a transverse direction of the trolley and a means of locking the module in the extension.
    [0006] Furthermore, the invention is also characterized by the combination of spheres mounted on the structure, where the reinforcement structure slides, and fastens to tighten the reinforcement structure on the structure.
    [0007] The extensions can therefore be moved between a position in which they are closest to each other, and in which they can grab the module and lift it, and a position in which they are retracted, which allows the module to be conveniently positioned between them. The locking means keep the module in extension even when the supports are turned. By raising the supports the
    Petition 870190121076, of 11/21/2019, p. 6/18
    3/7 module can be gripped.
    [0008] The module can be rotated through large angles, sufficient to rotate it by a quarter of a circle between a normal horizontal position and a vertical position in which impurities can fall, by direct control of the rotation of the axes by which the supports are connected to the arms, using a rotation device belonging to the arm when the axis belongs to the support (or vice versa). The extensions and the locking means are designed to interrupt the rotating movements of the module by cooperating with the module support means that are in contact with them, by means of, for example, locks with flat faces or section adjustments polygonal inlays, notably square sections.
    [0009] The position of the cart during the reception or removal of the module can be adjusted and maintained by the operation of a positioning device, which can consist of a partition with slanted or chamfered edges positioned on one face in the direction of the length of the structure and a fixed lock.
    [00010] The finer adjustment of the cart position, instead of its reinforcement structure, which is very useful for the correct positioning of the supports, is provided by the combination of balls and brakes; it is then possible to immobilize the reinforcement structure in the structure, or to move it in any direction of a plane with any degree of precision that may be desirable. In combination with the vertically movable arms, it is also possible to move the supports in all spatial directions, and thus also facilitate the gripping of the module.
    [00011] According to a favorable design of the invention, the extensions revolve around the axes of the supports. As for the locking means, they can include fasteners with a closing device installed in the extensions.
    [00012] The invention will now be described in more detail with
    Petition 870190121076, of 11/21/2019, p. 7/18
    4/7 reference to the following figures:
    [00013] Figure 1 is an overview of the cart and its surroundings;
    figure 2 is a detailed view representing the junction between the structure and the reinforcement structure;
    and figure 3 is a detailed view representing more particularly the means for supporting the module in the cart.
    [00014] The cart has the reference 1 in figure 1. Then the module 2, which in this case is a main assembly module, with an aircraft engine fan. The module 2 was previously installed on a fixed support 3, and must be transported on the cart 1 to an assembly frame 4, where it must be moored with another module 5, or directly to the frame 4. Station 3 consists of a support 6 of the which an oblique column 7 rises where module 2 is initially slid.
    [00015] Cart 1 includes a lower frame 8, wheels 9 installed on a frame 8 allowing cart 1 to be moved, and a reinforcement frame 10 installed on cart 8. Module 2 rests on cart 1 through the frame reinforcement 10. Figure 2 illustrates that this reinforcement structure 10 is slidably installed on the cart 8, resting on tongues 19 with a flat bottom surface in balls 11 maintained on the cart by lower walls 12 surrounding them. This design allows the reinforcement structure 10 to be moved with great precision while leaving the cart 8 immobile, in order to position the reinforcement structure 10 with great precision with respect to module 2, and also module 2 with respect to the adjacent module 5 or gantry 4, and thereby to facilitate the extreme stages of the process. During transport, the reinforcement structure 10 is, however, maintained securely attached to the cart 8 by fasteners 13 that connect them, which can be elbow fasteners of a known type, each of which includes
    Petition 870190121076, of 11/21/2019, p. 8/18
    5/7 of a movable rod 14 ending in a skid 15, which can be pressed under the cart 8 by the action of a lever 16 installed in the reinforcement structure and consisting of a lever ending in a cam. The cart 8 and the reinforcement structure 10 are pressed against each other when the rods 14 are pulled. Other fasteners, which are not shown, can be added to the locking wheels 9.
    [00016] The reinforcement structure 10 supports, on each of the lateral sides of the cart 1, a structure 17 receiving the module 2 which is illustrated in greater detail in figure 3. Each receiving structure 17 includes a structure 18 with rigid metallic elements that have approximately a diamond shape, and that end in tongues 19. The structure 18 carries in its center an arm 20 pointing vertically, and which also slides vertically under the action of a handle 21 that controls the same by a transmission 22 ending with a worm screw 23. The top of the arm 20 carries a support 24 shaped like a thick plate, aligned in a plane along the length of the cart 1 and connected to the arm 20 by an axis 25 belonging to the support 24, aligned in the direction cross-section of the cart 1, which can be driven by a pneumatic screwdriver 26 belonging to the arm 20 in order to tilt the support 24 by a quarter turn or more. The support 24 carries, at one front end, an extension 27 capable of rotating about an axis 28 positioned, in the represented position, in the vertical direction. Its upper face supports a fastener 29 that can delimit a closed volume when a closure device, consisting, for example, of pins 30, is installed through its branches. The opening of fastener 29 is aligned towards the center of the cart 1, and then the extension 27 is aligned towards the front of the cart 1. [00017] Module 2 supports two rods 31 with a square section
    Petition 870190121076, of 11/21/2019, p. 9/18
    6/7 drained, aligned in an opposite radial direction, and approximately horizontal, in the original position belonging to the devices, known to those skilled in the art, which can be embedded in module 32 to facilitate its grip, and then removed. The rods 31, which have a polygonal section, fitted on fasteners 29 of identical section, hold module 2 firmly and prevent it from rotating.
    [00018] A description of how cart 1 is used is now provided. It is brought close to station 3, in column 7 from which module 2 is originally positioned. The position of the trolley 1 can be adjusted by a groove 32 consisting of a partition of the structure 8 at its front edge, and into which the projections 33 penetrate with recesses in the floor in a determined position with respect to the station 3 as the cart 1 advances. The lateral limits, whether oblique or chamfered, of the groove 32 slide on projections 33 and the central cart 1 in relation to the station 3. The approach movement is interrupted by a stop rail 34 to stop the cart 1, which is fixedly attached to a of the supports 24, against a lower point, which is not shown, of the module 2.
    [00019] The cart 1 is then very close to the receiving position of the module 2. Its position is adjusted by moving the reinforcement structure 10 in balls 11, and then by the new tightening of the fasteners 13. The heights of the supports 24 are adjusted by individual movement of the arms 20. The extensions 27 are rotated, from a position in which they are pointing towards the front of the cart 1, to a position in which they cross the point inwards, towards each other, and where the fasteners 29 surround the rods 31. The pins 30 are positioned to completely immobilize those rods. A small upward movement of arms 10 allows module 2 to be raised from column 7, after which cart 1 can be moved to remove module 2. The pneumatic screwdriver
    Petition 870190121076, of 11/21/2019, p. 10/18
    7/7 tica 26 is turned on before reaching the groove in order to turn module 2 by positioning its axis vertically, and causing any impurities that may have been introduced between its rotor and its stator to fall. An inverted turn operation is then performed to make the rotary axis of the module 2 horizontal once again. Since the support of module 2 is caused by the flat faces of the rods 31 on the flat faces of the extensions 27, the turning operation is performed without obstacles. The trolley 1 is positioned adjacent to the gantry 4, where the groove 32 or a comparable groove located on the other side in the length direction can still be operated with the projections comparable to the projections 33. The position of the module 2 is adjusted once again by the movement the reinforcement structure 20 with respect to the structure 8, and the movement of the arms 10, so that the module 2 moor with the adjacent module 5 by these movements in all directions; the set of modules 2 and 5 can then follow, after which the fasteners 29 are unlocked, and the extensions 27 are removed from the rods 31. The cart 1 is removed. No crane is used. In exactly the same way, module 2 can be mounted directly on the support elements of gantry 4, if no other module has yet been installed on it.
