Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance, in particular to a warning device for elevator maintenance. Background Art

[0002] The role of elevator maintenance: to ensure the safety performance of elevators. By carefully inspecting, cleaning, lubricating and making necessary adjustments and replacements of various elevator components, potential safety hazards can be discovered and eliminated in a timely manner, such as wire rope wear, brake failure and other problems, to ensure the safety of passengers and extend the service life of elevators. Scientific and reasonable maintenance can reduce abnormal equipment wear, maintain stable elevator performance, and reduce downtime, thereby improving elevator efficiency and service quality. Complying with laws and regulations and performing maintenance according to prescribed cycles can help avoid legal risks, ensure the compliance of elevator operators, and enhance the public's trust in the use of elevators. Therefore, the elevator needs to be shut down during maintenance and inspection. Therefore, a warning device needs to be installed at the elevator door to serve as a reminder to people coming and going in the elevator.

[0003] According to announcement number CN216190158U, a warning sign for elevator maintenance is proposed, comprising a base plate, a fan fixedly connected to the upper surface of the base plate, an LED light fixedly connected to the upper surface of the base plate and located between the fans, a monitoring device provided on the lower surface of the base plate, the monitoring device comprising a tension sensor, a protective cover, a metal ball, and a thin rope, and a warning tube fixedly connected to the upper surface of the base plate and located outside the fans. This utility model, through the design of a monitoring device and a Bluetooth module, can automatically sound an alarm when the warning sign is moved, thus preventing the warning sign from being removed due to absence of personnel and resulting in ineffective early warning. The design of a warning tube and a cloth strip makes it easier to move the warning sign, thus preventing the large size of the warning sign from being unable to be moved in large quantities. In addition, the swinging cloth strip increases the warning effect of the device. The design of the warning tube and LED light ensures that the warning effect is still effective in dark environments, thus preventing accidents caused by the dark environment.

[0004] According to the above introduction, the existing elevator maintenance warning device is only placed at the elevator door when in use. When the passing staff accidentally bump into the warning device, the warning device is easily tipped over, which reduces the stability of the placement of the elevator maintenance warning device and affects the warning effect of the warning device on the passing personnel. In order to solve the above problems, an elevator maintenance warning device is proposed. Utility Model Content
