Three-node compensating device for wire rope sets of elevator

Abstract

Disclosed is a three nodal point pressure-equalising device of steel rope sets for an elevator, wherein a two nodal point pressure-equalising assembly (2) and a first spherical nodal point (9) can respectively rotate around a balancing seat (1); the balancing seat (1) can rotate around a base seat (3); each second spherical nodal point (26) can rotate around the two nodal point pressure-equalising assembly (2), while the rotational centre of the two nodal point pressure-equalising assembly (2) is on the same horizontal plane as the rotational centre of the two second spherical nodal points (26) provided thereon, and is collinear; the rotational centres of the two nodal point pressure-equalising assembly (2), the balancing seat (1) and the first spherical nodal point (9) are on the same horizontal plane and are collinear; the distance from the rotational centre of the two nodal point pressure-equalising assembly (2) to the rotational centre of the balancing seat (1) is half the distance of the first spherical nodal point (9) to the rotational centre of the balancing seat (1). The device can adjust the pressure sustained by three 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.

Description

technical field [0001] The invention relates to an improvement of a force equalizing device for steel wire rope groups for elevators, in particular to a device that can adjust the stress of three groups of steel wire ropes and make the stress of each group of steel wire ropes reach the same level for the three joints of the steel wire rope groups for elevators. force device. Background technique [0002] At present, elevators at home and abroad usually use a traction machine to drive the elevator. The suspension hoisting system of the traction elevator is composed of main components such as a traction sheave, a wire rope set, a car, and a balance weight system; The friction force generated by each steel wire rope in the traction wheel winding in the groove of the traction wheel provides the power to lift or lower the car; under the adjustment of the continuous development of elevator drive technology, the lifting height and driving speed of the elevator have greatly improved...

AI Technical Summary

Problems solved by technology

Therefore, the steel wire rope with high stress that has been used for a long time is easy to break during use, resulting in an elevator safety accident; , will also cause the breakage of the steel wire rope, which will cause elevator safety accidents; for this reason, we have developed a steel wire rope group for elevators that can adjust the force of the three sets of steel ropes and make the force of each set of steel ropes reach the same level.
