Background
In recent years, accidents in which a person outside a landing door accidentally falls into an elevator shaft are frequently caused by the landing door being impacted by an external force to cause the landing door guide shoe to fall off the grooved door leaf. The elevator at present usually adopts a suspended sliding landing door, which mainly comprises a door leaf, a door pulley, a door guide rail, a door sill, a door guide shoe and the like, wherein the door pulley is positioned at the upper part of the landing door, the landing door is suspended on the door guide rail through the pulley, the door guide shoe is arranged at the lower part of the landing door, and the guide shoe is embedded into a landing groove. When the door sill is in work, the guide shoe slides along the sill groove and is matched with the door pulley to play a role in guiding and limiting. The door leaf falling accident of the landing door caused by external force impact is mainly related to the horizontal impact force, the door leaf strength and the engaging depth of the landing door guide shoes. Among the three factors, although the landing door impact resistance can be improved by changing the thickness or strength of the door leaf for the elevator in use, the amount of change of the landing door for the elevator is large, and the high cost of the change is increased. Therefore, the method is an effective method for avoiding the accident of inclined falling of the door leaf by checking and adjusting the engagement depth of the layer door guide shoes and ensuring that the engagement depth of the elevator layer door guide shoes is within a safe size range. For an elevator in use made according to GB7588-2003 (without the amendment No. 1), the minimum value of the depth of engagement of the horizontal sliding landing door shoes should be no less than 15 mm. For the elevator which can not adjust the depth of engagement to meet the above requirements, the minimum value of the depth of engagement of the guide shoes of the horizontal sliding landing door should be not less than 12mm, and a safety warning sign should be arranged on each landing door. Therefore, in the regular inspection and maintenance process of the elevator, it is necessary to enhance the detection of the engagement depth of the elevator landing door guide shoe, and an effective elevator landing door guide shoe engagement depth detection device is developed. The existing landing door guide shoe measurement adopts a vernier caliper or a ruler for measurement, because the width of a sill groove is small, the distance between a landing door and the ground is small, the vernier caliper is difficult to insert into a sill groove for measurement, the ruler can only be obliquely placed into the sill groove, and the meshing depth of the landing door guide shoe cannot be accurately and quickly measured.
