Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an elevator door opening protection device. Background Art

[0002] In construction projects, it is usually necessary to protect the door opening of the elevator shaft to prevent people or objects from falling from high altitudes and to ensure the safety of construction. The size of the elevator door opening often deviates due to design and construction factors. Therefore, in the process of protecting the elevator door opening, the width of the elevator protective door is often processed to be wider than the width of the elevator door opening, so that the elevator protective door can adapt to elevator door openings of different sizes. However, this method will have the following problems: First, increasing the width of the elevator protective door will increase the weight of the elevator protective door itself and increase the difficulty of installing the elevator protective door. When the size deviation of the elevator door opening is large, the elevator protective door still cannot effectively cover the elevator door opening; secondly, the connection between the elevator protective door and the elevator door opening is usually fixed with expansion bolts. This connection method is not convenient for the disassembly of the elevator protective door, and the installation position of the elevator protective door cannot be adjusted. The expansion bolts are driven into the wall of the elevator door opening, which will also cause damage to the wall. The wall needs to be repaired later, the construction efficiency is low, and there will be problems with loose connections. In the process of protecting the elevator door opening, there is also a way to set up guardrails at the elevator door opening. The guardrails are made of multiple parallel steel pipes. When installing the guardrails, the two ends of the steel pipes are respectively fixed on the walls on both sides of the elevator door opening. Compared with the elevator protective door, the guardrails can reduce the weight. However, there are gaps in the structure of the guardrails themselves. When construction is carried out near the elevator door opening, it is easy for construction tools to fall from the gap into the elevator shaft, affecting the safety of construction.
