Abstract
1. Гидравлическая система для перемещения каретки (110), направляемой для перемещения вдоль линейного пути посредством опорной рамы (112), содержащая два гидравлических цилиндра (114, 116), каждый из которых имеет цилиндрический корпус (114а, 116а) и поршневой шток (114b, 116b), при этом цилиндрические корпуса (114а, 116а) двух гидравлических цилиндров соединены друг с другом, причем конец поршневого штока (114b) одного гидравлического цилиндра (114) соединен с опорной рамой (112), и конец поршневого штока (116b) другого гидравлического цилиндра (116) соединен с кареткой (110), отличающаяся тем, что два поршневых штока (114b, 116b) выступают из одной и той же стороны соединенных цилиндрических корпусов (114а, 116а), и в каждом концевом положении каретки (110) поршневой шток соответствующего одного из гидравлических цилиндров полностью выдвинут, и поршневой шток другого гидравлического цилиндра полностью отведен.2. Гидравлическая система по п.1, отличающаяся тем, что соединенные цилиндрические корпуса (114а, 116а) имеют выступающий палец (120), введенный в щель в направляющей (118), имеющей возможность перемещения с кареткой (110) для предотвращения нарушения выравнивания между осями поршневых штоков (114b, 116b) и цилиндрическими корпусами (114а, 116а), когда они находятся под нагрузкой.3. Гидравлическая система по п.1 или 2, отличающаяся тем, что два гидравлических цилиндра (114, 116) имеют разную длину хода, и второй поршневой шток (116b) соединен со стороной каретки (110), которая находится ближе к стороне рамы (112), к которой присоединен первый поршневой шток (114b).4. Гидравлическая система по п.3, отличающаяся тем, что содержит фиксированный защитный экран, установленный на раме, для защ�1. A hydraulic system for moving a carriage (110) guided to move along a linear path through a support frame (112), comprising two hydraulic cylinders (114, 116), each of which has a cylindrical body (114a, 116a) and a piston rod (114b , 116b), while the cylindrical bodies (114a, 116a) of the two hydraulic cylinders are connected to each other, with the end of the piston rod (114b) of one hydraulic cylinder (114) connected to the support frame (112), and the end of the piston rod (116b) of the other hydraulic cylinder (116) is connected to the carriage (1 10), characterized in that the two piston rods (114b, 116b) protrude from the same side of the connected cylindrical bodies (114a, 116a), and at each end position of the carriage (110) the piston rod of the corresponding one of the hydraulic cylinders is fully extended, and the piston rod of the other hydraulic cylinder is fully retracted. 2. The hydraulic system according to claim 1, characterized in that the connected cylindrical bodies (114a, 116a) have a protruding pin (120) inserted into the slot in a guide (118) that can move with the carriage (110) to prevent misalignment between the piston axes rods (114b, 116b) and cylindrical bodies (114a, 116a) when they are under load. 3. The hydraulic system according to claim 1 or 2, characterized in that the two hydraulic cylinders (114, 116) have different stroke lengths, and the second piston rod (116b) is connected to the side of the carriage (110), which is closer to the side of the frame (112) to which the first piston rod (114b) is attached. 4. The hydraulic system according to claim 3, characterized in that it contains a fixed protective screen mounted on the frame, for protection
