Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a high-temperature resistant and fireproof residential building elevator door hanging plate. Background Art

[0002] The elevator door machine hanging plate assembly plays an important role in the entire elevator device. The elevator door machine hanging plate assembly is mainly used to fix the elevator door knife, the elevator door lock and lift the elevator door machine door panel, so that the elevator door panel can be opened or closed. After searching, the Chinese patent publication number CN219384416U discloses an elevator door machine hanging plate assembly, which is provided with a cylindrical connecting column on both sides of the reinforced fixing column, and the inner side of the cylindrical connecting column is provided with a thread, and the cylindrical connecting column is fixedly connected to the hanging plate through the thread. The reinforced fixing column shares part of the pressure for the guide wheel, making the service life of the guide wheel longer, and avoiding the situation that the elevator door cannot be completely closed due to long-term use. When using this technical solution, the wire rope needs to be passed through the transmission wire rope fixer to limit the position, and the transmission wire rope fixer is cylindrical, and the transmission wire rope is fixed through the transmission wire rope fixer, which is inconvenient to install and remove the wire rope.

[0003] The Chinese patent publication number CN217458398U discloses a high-temperature resistant fireproof door hanging plate. This utility model reasonably matches different components of the hanging plate made of high-temperature resistant materials with different expansion coefficients, so that the hanging plate can maintain working stability and smoothness in a high-temperature environment; by setting fireproof components on the hanging plate, when a fire occurs in the elevator, it can timely prevent the spread of the fire, further improving the safety of elevator use. Although this technical solution can prevent the spread of fire, in order to ensure the normal use of the flame retardant tank in actual use, the flame retardant tank needs to be regularly disassembled and inspected, and the hanging rings on both sides of the technical solution are fixedly connected, which is not convenient for the rapid installation and removal of the flame retardant tank.
