1. A system for levelling a mechanical apparatus comprising a first mechanical apparatus levelling mechanism and a second mechanical apparatus levelling mechanism, each mechanical apparatus levelling mechanism comprising:
a base comprising an upper end face;
an adjusting screw rod;
an adjusting plate;
a support plate; and
an anti-rollover device, arranged at a bottom end face of the support plate,
wherein an upper end portion of the adjusting screw rod is penetrable into the anti-rollover device, such that a top end face of the adjusting screw rod and a bottom end face of the support plate come into contact with each other;
wherein the adjusting screw rod of the first mechanical apparatus levelling mechanism penetrates the adjusting plate of the first mechanical apparatus levelling mechanism along an axial direction and the adjusting screw rod of the first mechanical apparatus levelling mechanism is connected to the base of the first mechanical apparatus levelling mechanism;
wherein the adjusting screw rod of the second mechanical apparatus levelling mechanism penetrates the adjusting plate of the second mechanical apparatus levelling mechanism along an axial direction and the adjusting screw rod of the second mechanical apparatus levelling mechanism is connected to the base of the second mechanical apparatus levelling mechanism;
wherein the support plate of the first mechanical apparatus levelling mechanism is mounted at a top end of the adjusting screw rod of the first mechanical apparatus levelling mechanism and is located above the adjusting plate of the first mechanical apparatus levelling mechanism;
wherein the support plate of the second mechanical apparatus levelling mechanism is mounted at a top end of the adjusting screw rod of the second mechanical apparatus levelling mechanism and is located above the adjusting plate of the second mechanical apparatus levelling mechanism;
wherein the first mechanical apparatus levelling mechanisms can be brought in a zero position in which the adjusting plate of the first mechanical apparatus levelling mechanism is located on the base of the first mechanical apparatus levelling mechanism, and the second mechanical apparatus levelling mechanisms can be brought in a zero position in which the adjusting plate of the second mechanical apparatus levelling mechanism is located on the base of the second mechanical apparatus levelling mechanism, wherein an extension of the first mechanical apparatus levelling mechanism in its zero position, said extension being along an axial direction given by the adjusting screw rod of the first mechanical apparatus levelling mechanism, is equal to an extension of the second mechanical apparatus levelling mechanism in its zero position, said extension being along an axial direction given by the adjusting screw rod of the second mechanical apparatus levelling mechanism;
wherein the adjusting plate is rotatable to adjust the support plate vertically.
