Abstract (en)
Disclosed is a two nodal point pressure-equalising device of steel rope sets for an elevator, comprising a pres - sure-equalising device main body (1); wherein the pressure-equalising device main body (1) is rotatably provided on a base seat (5); two spherical nodal points (8) are symmetrically provided on the pressure-equalising device main body (1); the centre of the spheric¬al nodal points (8) is provided with a through hole (9); the through hole (9) is used for mounting a steel rope; the spherical nodal points (8) can rotate around the pressure-equalising device main body (1); the rotational centre of the pressure-equalising device main body (1) is located on the centre line thereof; and the rotational centre of each spherical nodal point (8) is on the same hori - zontal plane as the rotational centre of the pressure-equalising device main body (1) and is collinear. The device can adjust the pres - sure sustained by two sets of steel ropes, and when a stable state is reached, the pressure sustained by each steel rope set 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.
