Embodiment Construction

[0025] 1. Introduction to the functions of the main components of the device of the present invention

[0026] The auxiliary counterweight is used to balance the weight difference between the car 4 on both sides of the traction sheave 1 and the counterweight. From Figure 5 It can be seen that a set of energy-saving device has a secondary counterweight, and its installation and moving position is in the upper and lower space between the side of the counterweight and the wall of the hoistway.

[0027] The docking or unloading of the auxiliary counterweight during the operation of the elevator is realized by the action of the pulling hand 13 in the energy-saving device to connect, loosen the traction and fix the steel wire rope 9 of the auxiliary counterweight. Counterweight dynamic balancing instructions.

[0028] The counterweight is on the bottom floor, and when the empty car needs to go down on the top floor, the weight difference between the two sides of the traction shea...

Abstract

The invention belongs to the technical field of energy saving for elevators and specifically relates to an automatic balancing energy-saving device for an elevator car adopting assistant counterweight and a counterweight. The energy-saving device comprises a counterweight-side weight sensor, an elevator car-side weight sensor, a dragging brake and crown block combiner, a dragging cable crown block, a dragging and fixing pair counterweight cable, a counterweight frame, a counterweight block, an assistant counterweight frame, an assistant counterweight block, a dragging hand and a guide rail. When the elevator ascends or descends in response to a calling signal and the load in the elevator car is in dynamic change, the energy-saving device enables the counterweight to automatically load or unload the assistant counterweight according to the information about the weight difference on the elevator car side and the counterweight side sensed by an elevator weight sensor, so as to achieve the balance of the forces on the two sides of a dragging wheel. The balance-point load weight is generally set as 50% of rated loading capacity. When the energy-saving device is used, the elevator is driven and the energy is consumed only when the load of the elevator car exceeds the balance point. If the load of the elevator car is under the balance point, the running of the elevator only needs to overcome the ultra-low energy consumption of a friction force of the cable, so that the energy-saving effect is very obvious.

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 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 ways to drive vertical elevators, and the most widely used one is traction drive. [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. Therefore, the rated load function of the eleva...
