Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to an automatic fault alarm with a segmented alarm function. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. There are also step-type ones, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment serving specified floors. A vertical lift has a car that runs between at least two vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving mode. When an elevator fails, in order to repair the elevator in a timely manner, it is necessary to monitor the elevator's operating status in real time through an automatic fault alarm so that the staff can understand the elevator's operating status in a timely manner.

[0003] For example, the Internet-based automatic alarm for elevator faults, published as CN210854843U, uses vibration sensors and acceleration sensors for detection and transmits the detection data to a single-chip microcomputer, which imports the data into a comparison module. When the operating safety value set for the elevator body is exceeded, the alarm module generates an alarm message and uploads it to the community monitoring background through a wireless transmission module, so that community staff can understand it in time and notify the elevator maintenance personnel to carry out timely repairs, thereby improving the operating safety of the elevator body and reducing the trapped time of trapped people. At the same time, it has a good automatic alarm function.

[0004] When inspecting and maintaining the automatic fault alarm, the above patent needs to use a screwdriver to turn the screws connecting the inspection plate and the automatic fault alarm, turn the screws out of contact with the automatic fault alarm, and then remove the inspection plate to inspect and maintain the interior of the automatic fault alarm. This inspection and maintenance method is relatively complicated and not convenient for rapid inspection of the automatic fault alarm. Utility Model Content

[0027] In specific implementation, when the elevator is running, in order to monitor the operating status of the elevator, an automatic fault alarm is needed to be used so as to promptly discover problems with the elevator. When the automatic fault alarm is repaired, by pressing the rack rod 10, the rack rod 10 will mesh with the first gear 11 and the second gear 12 when it moves, driving the first gear 11 and the second gear 12 to rotate synchronously. When the first gear 11 and the second gear 12 rotate, they will respectively drive the two sets of pulleys 13 to rotate, so that the pulley 13 rotates to reel in the pull rope 14. When the pull rope 14 is reeled in, it will pull the block 15 to move. When the block 15 moves, it will press the first spring on one side. 16 is squeezed to shrink.

After the maintenance is completed, the inspection door 8 is docked with the mounting groove inside the body 1. When the inclined surface on one side of the block 15 contacts the connecting block 17, the block 15 will move and squeeze and shrink the first spring 16 on one side. When the block 15 contacts the card groove inside the connecting block 17, the first spring 16 will reset and push the block 15 to engage with the connecting block 17 to complete the closure of the body 1. In this way, the above operation can facilitate the maintenance of the automatic fault alarm.
