Problems solved by technology

However, the increase in memory capacity will increase the cost, and it is necessary to repeat many experiments in advance to set the appropriate speed parameters
[0011] In addition, on the other hand, in recent years, in buildings, the length of the inter-floors has changed greatly. In order to complete the inter-floor adjustment operation approximately at the same time as the arrival of the elevator, the operation speed of the inter-floor adjustment must be increased.
Therefore, noise and vibration are generated during driving, which deteriorates ride comfort.

no. 1 Embodiment approach

[0035] First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 9 .

[0036] Fig. 1 is a diagram showing the configuration of an elevator with a floor-to-floor adjustment function according to a first embodiment of the present invention. In addition, here, a double-deck elevator having two car chambers (hereinafter referred to as an upper car and a lower car) 2 and 3 on one car frame 1 will be described as an example.

[0037] A main hoisting rope 13 is wound around the hoisting machine 11 via a deflector pulley 12 and the like. Driven by the hoisting machine 11 , the car frame 1 is raised and lowered in the hoistway via the main hoisting rope 13 . An upper car 2 and a lower car 3 are connected to the car frame 1 so as to be movably vertically via ball screws 5a, 5b, 6a, 6b. These ball screws 5a, 5b, 6a, 6b are supported by the upper beam 1a and the middle beam 7, and are driven by the motors 4a, 4b to move the upper car 2 and the low...

no. 2 Embodiment approach

[0098] Next, a second embodiment of the present invention will be described with reference to FIGS. 10 and 11 . In addition, since the overall structure of an elevator, the data structure of each table, etc. are the same as those of the said 1st Embodiment, the description is abbreviate|omitted.

[0099] In the second embodiment, it is assumed that a preparatory operation for inter-floor adjustment is performed. In particular, it is characterized in that the preparatory operation start signal S2 output from the elevator control device 10 to the inter-floor adjustment control device 20 is divided into two types: an ascending preparatory operation start signal S21 and a descending preparatory operation start signal S22.

[0100] Next, the operation of the present embodiment will be described separately into (a) the raising operation during the normal operation and (b) the lowering operation during the normal operation.

[0101] (a) Ascent movement during normal operation

no. 3 Embodiment approach

[0123] Next, a third embodiment of the present invention will be described with reference to FIGS. 12 to 14 . In addition, since the overall structure of an elevator, the data structure of each table, etc. are the same as those of the said 1st Embodiment, the description is abbreviate|omitted.

[0124] The third embodiment of the present invention also presupposes that a preparatory operation for floor-to-floor adjustment is performed, as in the above-mentioned second embodiment.

[0125] Fig. 12 is a timing chart showing an ascending operation of an elevator in a controlled operation according to a third embodiment of the present invention.

[0126] The elevator control device 10 outputs the floor command signal S1 during at least a predetermined period of time after the elevator (car frame 1 ) travel start time t0 until the destination floor specifying operation start signal S3 is output.

[0127]Here, when there is steady running in the operation mode, the elevator control...

Abstract

The present invention provides an elevator having setting function between stairs, when switching from the normal performance to the supervision performance, the setting control deivce between stairs provisionally stops the setting action between the stairs of the car frame (steps B11, B12). When the car frame reaches the closest stairs, the lengths of the setting control device between stairs and the closest stairs proportionally adjust between stairs. Thus, it is capable of setting between the stairs without setting additional meter for supervision performance to complete the action withouteffecting the comfort of the passanger.

Description

technical field [0001] The present invention relates to an elevator having a car frame with at least two car rooms connected up and down, and more particularly to an elevator with an inter-floor adjustment function capable of adjusting the distance between the car rooms of the car frame in accordance with the inter-floor length of the destination floor elevator. Background technique [0002] In super high-rise buildings and the like, in order to improve the space efficiency of the building, elevators capable of transporting a large amount of cars are used as the vertical transportation means in the building. Such an elevator is called a "double deck elevator". [0003] Among the double-deck elevators, there is an elevator with an inter-floor adjustment function. The inter-floor adjustment function is as follows: even if the height of each floor of the building is not constant, the upper and lower car rooms can reach the destination simultaneously. The upper and lower car r...
