Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator door blocking, in particular to an elevator door blocking device with a warning function. Background Art
[0002] Elevators, as an indispensable means of vertical transportation in modern architecture, are widely used in various residential, commercial, and public buildings. Pit inspection and maintenance are key steps in elevator maintenance, especially when performing floor door maintenance, which requires personnel to enter the elevator shaft. Typically, elevator floor doors have an automatic closing function due to internal springs or counterweight mechanisms, which is crucial for the normal operation of the elevator. However, when elevator maintenance personnel enter the pit for maintenance, they usually need to manually secure the floor doors in an open state to prevent them from automatically closing. At this time, with the floor doors in the open state, accidents are prone to occur, especially when there are no effective warning signs or physical protective measures. Passersby or non-staff members may mistakenly enter this opening, causing them to accidentally fall into the elevator pit and cause injury.
[0003] At present, in response to this situation, the elevator industry generally adopts measures such as using tools such as door locks or screwdrivers to fix the floor doors to prevent them from closing on their own. However, these traditional methods are limited to technical protection and lack effective safety warning functions and physical barriers for non-staff. What is more serious is that when the elevator floor doors are opened, there are usually no clear warning signs or physical barriers to inform passers-by that there is a danger in the area. Therefore, how to provide sufficient safety warnings to passers-by when the floor doors are opened without interfering with the normal operation of the elevator, and at the same time effectively block non-staff, has become a safety hazard problem that needs to be urgently solved in the elevator maintenance process.
