Embodiment Construction

[0029] 1. Introduction to the functions of the main components of the device of the present invention

[0030] The auxiliary counterweight 11 is used to balance the weight difference between the 4 cars and the 3 counterweights on both sides of the 1 traction sheave. From Figure 7 It can be seen that a set of energy-saving devices has four sets of secondary counterweights, which are installed on the hoistway walls on both sides of the car, with two sets on each side. The installation guide rail of the car has divided the elevator shaft wall into front and rear areas, so each side has a group of front and rear areas. Looking down from the top of the hoistway, the auxiliary counterweights arranged diagonally can be used in pairs to ensure the balance of forces on all sides of the car, or they can be used individually as needed.

[0031] The docking or unloading of the auxiliary counterweight during elevator operation is realized by the 12 traction hands in the energy-saving de...

Abstract

The invention belongs to the technical field of energy saving of an elevator and particularly relates to an elevator car and counterweight automatic balancing energy-saving device with auxiliary counterweights. The energy-saving device comprises a counterweight side weight sensor, an elevator car side weight sensor, a traction braking and fixed pulley combiner, a traction steel wire rope fixed pulley, a fixed auxiliary counterweight steel wire rope, a traction steel wire rope, auxiliary counterweights, a traction manipulator, a guide rail, a control system and the like. When an elevator answers a calling signal to ascend or descend and the load in the elevator car is dynamically changed, the energy-saving device enables the elevator car to automatically hook or unload the auxiliary counterweight according to information of the difference between the weights measured by an elevator weight sensor at the elevator car side and the counterweight side, so that the balance of forces at two sides of a traction wheel is achieved; and the loading capacity at a balance point is generally set as 50 percent of the rated loading capacity. With adoption of the energy-saving device, only when the load of the elevator car exceeds the balance point, does the elevator need to be driven with energy consumption; and when the load is below the balance point, the elevator only needs to overcome friction of the steel wire rope and consumes extremely low energy, and the energy-saving effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of elevator energy saving, and in particular relates to an energy saving device and control system for vertical elevator operation. Background technique [0002] The energy consumption of a vertical elevator (hereinafter referred to as "elevator") is mainly composed of four aspects: traction system, electrical control system, car lighting and ventilation system, 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 functi...
