Disclosed is a six nodal point pressure-equalising device of steel rope sets for an elevator, wherein each three nodal point pressure-equalising assembly (2) can rotate around a balancing seat (1); the balancing seat (1) can rotate around a base seat (3), three non-collinear spherical nodal points (25) are provided on each three nodal point pressure-equalising assembly (2), each spherical nodal point (25) can rotate around the three nodal point pressure-equalising assembly (2) provided with the spherical nodal points (25), while the rotational centre of the three nodal point pressure-equalising assembly (2) is on the same horizontal plane as the rotational centre of the spherical nodal points (25) provided thereon; and the rotational centre of each three nodal point pressure-equalising assembly (2) is on the same horizontal plane as the rotational centre of the balancing seat (1), and is collinear. The device can adjust the pressure sustained by six sets of steel ropes, and when a stable state is reached, the pressure sustained by each set of steel ropes will be the same, thereby enabling the damage caused by unequal pressure sustained by steel ropes for an elevator to be overcome, increasing the service life of the steel ropes.

Disclosed is a five nodal point pressure-equalising device of steel rope sets for an elevator, wherein two second spherical nodal points (35) capable of oscillating are provided symmetrically on the two nodal point pressure-equalising assembly; three non-collinear second spherical nodal points (35) capable of oscillating are provided on the three nodal point pressure-equalising assembly (3); the oscillation centre of the two nodal point pressure-equalising assembly (2) is on the same horizontal plane as the oscillation centre of two first spherical nodal points (26) provided thereon, and is collinear; the oscillation centre of the two nodal point pressure-equalising assembly (2), the oscillation centre of a balancing seat (1) and the oscillation centre of the three nodal point pressure-equalising assembly (3) are on the same horizontal plane, and are collinear; and the distance from the oscillation centre of the two nodal point pressure-equalising assembly (2) to the oscillation centre of the balancing seat (1) is 1.5 times the distance from the oscillation centre of the three nodal point pressure-equalising assembly (3) to the oscillation centre of the balancing seat (1). The present pressure-equalising device can automatically adjust the pressure sustained by five sets of steel ropes, ultimately making the pressure sustained by each set of steel ropes the same, thereby enabling the damage caused by unequal pressure sustained by steel ropes for an elevator to be overcome.
