Problems solved by technology

[0027] like Figure 9 The structure of the elevator door shown has the following problems: if the distance between the lever 113 of the locking mechanism 109 and the lever receiving part 115 is not proper, the garbage accumulated in the ditch of the landing door sill 106a and the hanger rail 107a will cause the car The compartment door 103 cannot move normally
However, when detecting the engagement position, the load of the car is not considered. If the load of the car changes on each floor, there will be a problem that the correct position cannot be detected.
That is, if the load changes and the car itself tilts, the horizontal component of the tilt will affect the measurement

[0096] Next, a second embodiment of the present invention will be described.

[0097] Figure 5 It is a schematic diagram of the composition of the single-open elevator door in the second embodiment of the present invention. Figure 5 (a) is the landing door 102, Figure 5 (b) is a car door 103, and shows the structure when it sees from inside, respectively. Also, with Figure 7 The same symbols are used for the same parts, and detailed description thereof will be omitted here.

[0098] In the second embodiment, a reflective laser displacement meter 301 is installed on the door panel 104b of the car door 103 , and a reflective plate 302 opposite to the laser displacement meter 301 is provided at the closing end of the landing door 102 .

[0099] The laser displacement meter 301 measures the distance to the reflecting plate 302 as the car door 103 closes. The reflector 302 is not arranged on the door panel 104a for opening and closing, but is fixed on the lift passage wall...

Abstract

The present invention relates to a diagnostic device for an elevator door. A load-carrying load of a car (20) is detected by a load sensor (204) in each floor. When detecting the car in a non load state, a mobile distance of the car door from a door-opening motion of the car door to a position where a locking mechanism of a layer station door is released is measured by pulse numbers of a pulse generator (203). Based on the measured value, a joggling state of the layer station door and the car door is diagnosed, thereby it is capable of examining at an appropriate moment.

Description

technical field [0001] The present invention relates to an elevator door diagnosis device for diagnosing the state of an engaging portion between a door provided on an elevator car (hereinafter referred to as a car door) and a door provided at a landing on each floor (hereinafter referred to as a landing door). Background technique [0002] Generally, an elevator is configured such that a car door is engaged with a hall door as the elevator levels, whereby both doors are opened and closed in unison. At this time, the drive source is located on the side of the car door, and the landing door is linked to the car door. [0003] Figure 9 It is a schematic diagram showing the configuration of a conventional single-open elevator door. Figure 9 (a) is the landing door 102, Figure 9 (b) is a car door 103, and it shows the structure seen from the inside, respectively. The hall 102 is installed on each floor of the building. The car door 103 is installed in the car of the elevato...
