Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator car roof structure and an elevator car. Background Art

[0002] In order to ensure the stability, safety and comfort of the elevator during long-term operation, it is often necessary to perform maintenance work on the elevator car and the shaft in which it runs. In order to ensure the safety of workers, equipment and tools during the maintenance process, a guardrail of a certain height is usually set on the top of the car. During the actual maintenance work of the car, there is inevitably a certain deviation between the parking position of the car and the position of the shaft that needs maintenance work. The staff have to stand on the guardrail to work. Although the gap between the car and the shaft is small and people will not fall, there is still a risk of slipping for the workers. Falling on the top of the car may cause injuries or damage to the elevator parts.

[0003] Therefore, a technical solution is currently needed to solve the technical problem that during elevator maintenance operations, due to the possible deviation between the construction height and the car height, the workers need to stand on the guardrail on the top of the car to perform construction, which poses a safety hazard.
