Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator maintenance equipment, in particular to a simple elevator monitoring and maintenance door blocker. Background Art
[0002] The elevator monitoring system is a comprehensive system that integrates multiple technologies such as sensors, network communications, data processing, and artificial intelligence. Its main working principles include data collection, data transmission, data processing and analysis, and remote control. It is an important tool for real-time monitoring of the elevator's operating status. In order to ensure the safe operation of the elevator and improve the safety and reliability of the elevator, maintenance personnel are required to regularly maintain the elevator monitoring system. During the maintenance process, a door blocker is usually required to prevent the elevator door from closing automatically. The door blocker can not only avoid the risk of accidental closing of the elevator door during maintenance, but also ensure the safety and efficiency of the maintenance work.
[0003] According to the search, Chinese patent literature, announcement number: CN217172835U, discloses a simplified elevator monitoring and maintenance door blocker, which is placed by aligning the door blocker with the sill so that the expansion sleeve is inside the sill, and then vertical pressure is applied to the force rod by stepping on the pull cap, so that the filling piece is vertically embedded in the filling cavity of the expansion sleeve, and the expansion sleeve can be expanded outward and pressed against the inner wall of the sill, so as to conveniently achieve the purpose of installing the door blocker at the sill. However, in actual use, the device cannot be stably installed when facing different elevator door sills due to the different widths of different elevator door sills and the limited expansion coefficient of the expansion sleeve. In addition, the installation heights of the infrared transmitters of different elevator doors are also different, and the device cannot effectively block the emitted light, so the elevator door is still at risk of forced closure, which poses certain safety hazards.
