Transport carriage with two hexapod platforms with increased range of movement
A carriage with two hexapod platforms, each having a base, a plate, and a set of six cylinders associated in pairs. Each cylinder is articulatedly mounted with the plate. For each pair, a slider is able to move in translation on the base. For a first pair, the two cylinders of the first pair are mounted in an articulated manner on the slider. The articulation of one of the two cylinders of the first pair with the plate is adjacent to the articulation of one of the two cylinders of a second pair with the plate. The articulation of the other of the two cylinders of the first pair with the plate is adjacent to the articulation of one of the two cylinders of a third pair with the plate. For each slider, a movement system moves the slider. A control unit controls each cylinder and the movement system.
1. A transport carriage for joined wings of an aircraft, wherein said transport carriage comprises:
a plane of vertical symmetry,
a chassis mounted on wheels,
a set of supporting elements mounted on the chassis, each of which is configured to come to bear beneath a structure of the aircraft, and,
on either side of a median plane, a hexapod platform comprising:
a base secured to the chassis,
a plate configured to bear beneath a wing,
a set of six cylinders associated in pairs, wherein each cylinder is mounted so as to be articulated with the plate,
for each pair, a slider mounted so as to be able to move in translation on the base in a translation direction, wherein the two cylinders of said pair are mounted in an articulated manner on the slider, and,
for each slider, a movement system that moves the slider parallel to the translation direction.
2. The transport carriage according to claim 1 , wherein the plate has three articulation zones that are distributed at three vertices of a triangle, and, in each articulation zone, two cylinders from two different pairs are articulated to the plate.
3. The transport carriage according to claim 1 , wherein the three translation directions are horizontal and converge at a single point.
4. The transport carriage according to claim 3 , wherein the three translation directions are disposed at 120° with respect to one another.
5. The transport carriage according to claim 1 , wherein the base has a stop on which the plate comes to bear in a lowered position.
