Embodiment approach 1

[0024] Hereinafter, the counterweight adjustment method according to Embodiment 1 of the present invention will be described. In addition, in the description of the drawings, the same reference numerals are assigned to the same parts or corresponding parts, and overlapping descriptions will be omitted.

[0025] First, the overall structure of the elevator apparatus 100 which performs the weight adjustment of a counterweight using the counterweight adjustment method of Embodiment 1 of this invention is demonstrated. figure 1 It is an overall schematic diagram of the elevator apparatus 100 according to Embodiment 1 of the present invention.

[0026] The car 1 of the elevator apparatus 100 moves up and down in the hoistway 2 . A machine room 3 is provided above the hoistway 2 , and the machine room 3 includes a motor 4 , a sheave 5 , and a control device 6 .

[0027] The motor 4 is connected to a movement amount detector 41 . The movement amount detector 41 detects the rotatio...

Embodiment approach 2

[0137] Hereinafter, the counterweight adjustment method according to Embodiment 2 of the present invention will be described. In Embodiment 1, an example of calculating the adjustment amount of the counterweight 7 with the test weights stacked on the counterweight 7 was described. An example of calculating the torque constant and calculating the adjustment amount of the counterweight 7 under the state will be described.

Abstract

An adjustment calculation device for a counterweight of an elevator device comprises an operation control unit that lifts and lowers a car in a state in which the car is unloaded and in a state in which the car or the counterweight is loaded with a test weight of a known weight. The adjustment calculation device acquires the current supplied to an electric motor when the operation control unit lifts and lowers the car, calculates a conversion factor for the elevator device to be adjusted during installation, and accurately finds the adjustment for the counterweight, thereby improving adjustment precision for the counterweight and reducing the adjustment work during the installation.

Description

technical field [0001] The invention relates to a counterweight adjustment calculation device of an elevator device and an adjustment method of the elevator device. Background technique [0002] An elevator apparatus includes a motor driven by an electric current, and a sheave that rotates in conjunction with the motor. A rope is wound around the sheave, a car is installed at one end of the rope, and a counterweight is installed at the other end. The elevator apparatus supplies electric current to the motor to raise and lower the car. [0003] The counterweight is designed to balance the weight of the car when the load is half of the rated carrying capacity. In addition, structures other than the counterweight of the elevator apparatus, such as motors, control devices, etc., are also designed so that the counterweight and the weight of the car are balanced when the load is half of the rated carrying weight. However, at the installation place of the elevator apparatus, the...
