Embodiment Construction

[0024] 1. Introduction to the functions of the main components of the device of the present invention

[0025] The sub-pairs are reused to balance the weight difference between the car 6 and the counterweight 17 on both sides of the traction sheave 1 . from Figure 5 It can be seen that a set of energy-saving device has only one sub-counterweight frame, and traction wire rope adjustment devices 7 are installed on the left and right sides of the car bottom to pull the sub-counterweight lower pulley 14. in the upper and lower spaces in the middle.

[0026] The hoisting or unloading of the neutron counterweight during elevator operation is realized by the traction device 7 tightening and loosening the traction wire rope 4. The action and range of the traction device 7 are subject to the dynamic balance between the car and the counterweight accepted by the energy-saving device. Control instruction.

[0027] The counterweight is on the bottom floor, and when the empty car needs ...

Abstract

The present invention belongs to the technical field of energy conservation of elevators and particularly relates to a basket carrier type counterweight elevator car and a counterweight self-balancing energy-saving apparatus. A basket carrier type counterweight consists of a son counterweight and a basket carrier counterweight frame, wherein a basket carrier is mounted on the counterweight frame; the counterweight applied to dynamic balance is called the son counterweight; the counterweight not applied to the dynamic balance in the counterweight frame is called a mother counterweight; and the son counterweight and the mother counterweight are placed inside the basket carrier. The present invention aims to reduce the weight of the car side and the weight of the counterweight side of an elevator before running up and down with idle load or light load, and the reduced weight of the counterweight side is larger than that of the car side, so that the two sides are substantially the same in weight. Therefore, the rotation inertia output by a driving motor is reduced, thereby achieving the purpose of saving energy of the evaluator.

Description

technical field [0001] The invention belongs to the technical field of elevator energy saving, and in particular relates to an energy saving device for traction vertical elevator operation. Background technique [0002] The energy consumption of vertical elevators (hereinafter referred to as "elevators") is mainly composed of four aspects: traction system, electrical control system, car lighting and ventilation system, and door machine system, among which the energy consumption of traction drive accounts for an absolute Majority (generally 70% to 80%). [0003] There are many driving methods for vertical elevators, and the most widely used one is the traction driving method at present. [0004] The carrying capacity of the elevator is designed according to the full load demand. However, in the up and down operation, full load operation is not the normal state of elevator operation, and light load or even no load is actually the normal state of elevator operation. Therefor...
