A low energy consumption elevator counterweight energy-saving control system
ActiveCN115520752Bincrease frictionExtended service lifeElevatorsWinding mechanismsControl systemEnergy consumption
The present invention discloses an elevator counterweight energy-saving control system with low energy consumption, which relates to the technical field of elevator counterweights, and includes an elevator counterweight control device body, wherein the elevator counterweight control device body includes a bearing box and a counterweight box, and a bearing box buffer is fixedly installed on the ground of the inner cavity of the bearing box. The present invention adopts the cooperation between the counterweight lifting mechanism and the buffer mechanism, and the counterweight block drives the circular sliding sleeve to slide on the surface of the track slide rod through the traction of the steel cable. Through such an arrangement, it can play a supporting role while ensuring the effect of reducing friction during the lifting process, and the mutual cooperation of the auxiliary buffer roller and the elevator chassis track is used to improve the smoothness of the elevator chassis during lifting and lowering, and also reduce the friction during movement, so that it is more labor-saving, reduces energy consumption, reduces wear during long-term operation, and prolongs the service life and performance of the elevator.
