Background
Elevators are widely used in high-rise buildings for transporting passengers and goods, and with the great popularity and application of elevators, elevator safety issues are receiving more and more attention.
The lower guiding and holding device of the elevator is fixed on the door leaf of the elevator landing door through a bolt, and under the normal condition, the lower guiding and holding device is inserted into the floor groove of the landing door, and the landing door is prevented from being knocked open under the closed state by limiting the freedom degree of the door leaf.
When the elevator landing door is impacted by external force, the door guide shoe (also called a guide and retaining device or a sliding block) is separated from the sill sliding groove, so that the elevator landing door is separated from the sill, and safety accidents occur. The reason for this is that the door leaves are deformed elastically due to insufficient mechanical strength of the door leaves when the landing door is impacted by external force, and the guiding and holding device is driven to move upwards to cause insufficient engagement depth, which results in groove separation. Therefore, new requirements are placed on the elevator landing doors in the new-type test rules and the minimum depth of engagement allowed by the guiding and retaining means is specified to be reduced, requiring a new-type test, whereby the importance of verifying the depth of engagement at the time of inspection can be seen.
