Control device of elevator door

Abstract

Provided is a control device of an elevator door, which has simple structure and high precision measurement clamp clearance, in an operation device of the control device, when the clamp clearance between a clamping device of a car side elevator door and a clamping device of a hall side elevator door is measured under the state of each elevator door being closed, whether the elevator door is in the all-closed state can be conformed by respectively judging that whether an off state (ON state signal of an all-closed position detetcing switch of the car side elevator door of the elevator door all-closed state detecting signal is outputted or not, whether a moment instruction value enables the car side elevator door to output a certain moment value in the direction performing the closing action or not, and whether the elevator door speed is zero or not, after the elevator door is conformed in the all-closed state, as the changes of the moment instruction value when entering into the elevator door opening action to detect the increase of the moment instruction value generated when the clamping positions of each elevator are contacted with each other, and the clamp clearance can be measured according to the result of the moving distance of the car side elevator door.

Description

technical field [0001] The present invention relates to an elevator door control device having a function of measuring an engaging gap represented by a positional relationship of an engaging device when each elevator door is in a closed state, wherein the engaging device is installed on a side of a car On the elevator door and the elevator door on the lobby side, (this function is used during maintenance). Background technique [0002] In the existing elevator doors, the car-side elevator doors arranged on the elevator car for lifting and the hall-side elevator doors arranged on each floor form a double structure, and each elevator door is respectively provided with an engaging device. The engaging device is a device required to link the elevator door on the car side and the elevator door on the hall side to smoothly open and close. When lifting and lowering, each elevator door is in a closed state. In this state, the engaging device are in a state of non-contact with each ...

AI Technical Summary

Problems solved by technology

[0013] In the method for detecting (measuring) the engagement gaps of the respective engagement parts (each engagement device) of the elevator door involved in the above-mentioned Patent Document 1, from the structural point of view of the engagement gap detection device, it is necessary to have all the floor halls The fully closed position switch is installed on the side elevator door, which will not only increase the number of parts and lead to an increase in the overall cost of the elevator equipment system, but also because the installation accuracy of each fully closed position switch of each hall side elevator door on all floors will affect the The detection accuracy of the engagement gap of each engagement part is affected, so it is necessary to keep the installation positions of the full-close position switches of the elevator doors on the lobby side in a high-precision and appropriate setting state. If the full-close position switches If there is an error in the installation position, it is impossible to measure the engagement gap with high precision, which not only puts a heavy burden on the equipment itself, but also makes repair and maintenance work very troublesome.

[0014] In addition, in the method for detecting (measuring) the engagement clearance of the above-mentioned Patent Document 2, since it directly detects the moving speed of the elevator door itself, the vibration component generated by the movement of the elevator door is mixed in as an external disturbance factor. In the elevator door speed signal indicating the elevator door speed, there is a problem that it is difficult to perform high-precision detection due to adverse effects on signal processing
