Description

Technical Field

[0001] The utility model relates to the technical field of elevator shafts, in particular to a telescopic elevator shaft protection platform. Background Art

[0002] The elevator shaft protection platform is a device used to protect the safety of the elevator shaft. It is usually made of steel and fixed on the wall inside the shaft. It can cover the entire shaft opening to form an effective protective barrier. The main function of the elevator shaft protection platform is to prevent people or objects from falling from the shaft, prevent people inside and outside the shaft from accidentally entering or leaving, and provide a safe working environment. It is usually installed on the upper part of the shaft to prevent falling objects from interfering with or damaging the normal operation of the elevator.

[0003] Installing an elevator shaft protection platform will increase the difficulty of maintenance and repair work, especially when it is necessary to enter the shaft to maintain and repair elevator equipment. Operators may need to move or remove the protection platform, which not only increases the complexity and time cost of the work, but also may cause permanent damage to the wall. For this reason, we proposed a retractable elevator shaft protection platform. Utility Model Content
