Problems solved by technology
[0003] However, as the anti-vibration rubber ages, the anti-vibration rubber hardens to cause an error between the load detection value of the load detection device and the actual load in the car
In addition, in general, in such load detection devices, the load detection value may vary even with the same load (mass) due to changes in ambient temperature and installation conditions.
In the case of a difference in the load detection value, the car may move in the opposite direction at the time of departure, or may move in a jerky start, resulting in poor ride comfort

The invention provides a load detection adjusting device of an elevator, and the device adjusts a load detection value in maximum load, and special operation of a professional is not needed. In one embodiment, a photographed image of a car is analyzed to determine passengers (U), to obtain weight information of the passengers who are registered in advance. Then, according to the obtained weight information and a current car load detection value detected by a in-car load detection portion (41) which outputs a load detection value corresponding to the load in the car, a load detection value in maximum load equal to the load detection value of the car (6) in maximum load is calculated, and the calculated load detection value in maximum load is compared with a load detection value in maximum load registered in a recording portion (24), to determine whether the load detection value in maximum load registered in a recording portion (24) is good or not, and based on a determination result, the load detection value in maximum load registered in a recording portion (24) is corrected.
Description
technical field [0001] The present invention relates to a load detection and adjustment device for an elevator that adjusts a load detection value of a load detection device provided in a car, and an elevator. Background technique [0002] Conventionally, when an elevator is started to run a car, the quality of the car and counterweight is used to control the car to prevent the car from starting suddenly and to run smoothly. In this control, it is necessary to detect the load in the car during running, so a load detection device for detecting the load in the car is installed in the car. The load detection device is configured to calculate the load in the car based on the mass of a user riding on the car, an object, etc., based on the amount of bending of the vibration-proof rubber attached to the underfloor of the car. In order to calculate the load in the car, it is necessary to store load detection values at the time of no load and the time of maximum load in a nonvolat...
