Problems solved by technology

[0006] The embodiment of the present application provides an elevator rescue method and device, which solves the problem of the elevator encoder in the prior art, which immediately controls the elevator to stop running after the elevator encoder fails, and when the elevator car stops at the leveling area, the elevator rescue occurs. Difficult technical problems, achieved the technical effect of controlling the elevator car to run slowly to the leveling position and opening the elevator door when the encoder fails, so that passengers can get out of trouble in time when the elevator fails

Embodiment 1

[0055] In the specific implementation process, please refer to figure 1 , is a structural schematic diagram of the vertical elevator system, including: a traction motor 11, an encoder 12 arranged on the traction motor 11, a traction sheave 13 connected to the shaft of the traction motor 11 and driven by the traction motor 11, and The traction wire rope 14 arranged on the groove of the traction sheave 13, the two movable pulleys 141, 142 arranged on the traction wire rope 14, the elevator car 15 slidingly connected with the traction wire rope 14 through the movable pulley 141, and the movable pulley 142 A counterweight load 16 that is slidably connected with the traction wire rope 14. Wherein, the traction motor 11 and the traction sheave 13 are arranged on the upper side of the elevator fixing device 10, and the two ends of the traction wire rope 14 are fixedly connected to the lower side of the elevator fixing device 10, and because the middle part of the traction wire rope 1...

Embodiment 2

[0080] Based on the same inventive concept, the embodiment of this application also provides an elevator rescue device, which is applied to an elevator with an encoder. Please refer to Figure 4 , the device includes:

[0081] A fault detection unit 401, configured to detect whether the encoder is faulty and obtain a first detection result when the elevator is running in a closed-loop operation mode;

[0082] A switching control unit 402, configured to control the operation mode of the elevator to switch to an open-loop operation mode when the first detection result is yes;

[0083] An operation control unit 403, configured to control the elevator to run at a preset speed to the leveling position closest to the current position of the elevator car in the open-loop operation mode;

[0084] The stop control unit 404 is configured to control the elevator to stop running when the elevator car reaches the nearest leveling position, and open the elevator door to allow elevator pass...

Abstract

The invention discloses a rescue method and a rescue device for an elevator. According to the rescue method and the rescue device, the technical problems in the prior art that after an elevator encoder has faults, the elevator is immediately controlled to stop operating; when the stop position of an elevator car is not positioned in a flat layer area, the rescue is difficult to rescue are solved. The method comprises the following steps of when the elevator operates in a closed loop operation mode, detecting whether the encoder has faults or not to obtain a first detecting result; when the first detecting result is yes, controlling the operation mode of the elevator to be switched into an opened loop operation mode; under the opened loop mode, controlling the elevator to operate towards the flat layer position nearest to the current position of the elevator car at preset distance; when the elevator car operates to the nearest flat layer position, controlling the elevator to stop operating, opening an elevator door and enabling passengers in the elevator to leave from the elevator car. The technical effect that when the encoder has the faults, the elevator car is controlled to slowly operate to the flat layer position, and the elevator door is opened, so that the passengers can timely rescue when the elevator has faults, is realized.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator rescue method and device. Background technique [0002] As the elevator has gradually become an indispensable "floor transportation tool" in people's daily life, more and more people pay attention to its reliability, and its safe and humanized fault protection has become an important demand for the development of the elevator industry. [0003] The vertical elevator control system that people use more in daily life mainly includes: elevator traction machine (including motor, brake, reduction box and other components), encoder, and frequency converter; among them, the encoder is connected with the elevator traction machine, The frequency converter is connected with the traction machine and the encoder respectively; specifically, when the elevator is running in the closed-loop operation mode, the frequency converter provides three-phase voltage for the motor of the tr...
