Problems solved by technology

However, when the elevator is equipped with a geared traction machine that transmits the driving force of the motor to the traction wheels through the gears, there is a problem that due to the characteristics of the gears, even in the range of the characteristics of the motor when braking The internal control, also can not get the desired speed, acceleration

Embodiment approach 1

[0020] figure 1 It is a block diagram of the control apparatus of the elevator in Embodiment 1 of this invention. exist figure 1 Among them, 1 is the car that is lifted and lowered in the hoistway of the elevator; 2 is the counterweight that is lifted and lowered in the hoistway of the elevator in the opposite direction to the car 1. In the state in which half of the capacity of passengers is seated in 1, that is, in the state in which half of the rated load acts on the car 1, it is equal to the weight of the entire car 1. In addition, 3 is the main rope that is connected to the car 1 and the counterweight 2 and suspends the car 1 and the counterweight 2 in a bucket style; 4 is the main rope 3 that is wound around the rope groove formed on the outer peripheral surface and rotates with it. The traction sheave of the geared traction machine that moves the car 1 and the counterweight 2 up and down in linkage; 5 is the motor driven by the power supplied by the inverter 6; The g...

Embodiment approach 2

[0049] Figure 7 It is a block diagram of the control apparatus of the elevator in Embodiment 2 of this invention. exist Figure 7 Among them, 13 is a gear temperature detection unit, which detects the temperature of the gear 7 of the geared traction machine; 14 is a gear temperature judgment unit, which judges whether the temperature of the gear 7 detected by the gear temperature detection unit 13 exceeds a predetermined value. In addition, the gear temperature detection unit 13 may directly detect the temperature of the gear 7 or may indirectly detect the temperature of the gear 7 based on the temperature of gear oil used for the gear 7 . Other configurations are the same as those in Embodiment 1.

[0050] Next, operation|movement of the control apparatus of the elevator which has the said structure is demonstrated.

[0051] As in the first embodiment, the motor load calculation unit 10 detects the load acting on the motor 5 based on the detection result of the running di...

Abstract

A controller for an elevator equipped with a gear-type traction machine which transmits the driving force of a motor to a driving sheave via a gear, which is constituted by a car which ascends and descends in an elevator shaft, car load detecting means which detects a load acting on the car, operation direction detecting means which detects an operation direction of the car, and speed determining means which determines a maximum speed of the car according to characteristics of the motor during a power running operation and a maximum speed of the car according to characteristics of the gear of the gear-type traction machine during a braking operation on the basis of detection results of the car load detecting means and the operation direction detecting means.

Description

technical field [0001] The present invention relates to a control device of an elevator having a geared traction machine that transmits the driving force of a motor to a traction wheel (moving net car) through gears. Background technique [0002] Among conventional control devices for elevators, there has been proposed a control device for elevators that includes a car load detection unit that measures the weight of the car as the car load, and a next stop floor setting unit that sets the next stop floor. According to the car load obtained by the car load detection unit and the car moving distance obtained by the next stop floor setting unit, the maximum speed and acceleration of the car are changed within the allowable driving range of the motor of the traction machine, This shortens the running time of the car and improves the running efficiency of the elevator (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-238037...
