Description
Technical Field
The invention belongs to the technical field of elevator detection equipment and methods, and particularly relates to a non-contact automatic measuring device and method for the engagement depth of elevator door guide shoes.
Background
The guiding and maintaining device of the elevator door consists of an upper guiding and maintaining device and a lower guiding and maintaining device, wherein the door guiding shoe is an important lower guiding and maintaining device in the elevator landing door, and the landing door leaf is ensured to slide along the design direction by the matching of the door guiding shoe and the door sill track groove and maintain the original design position. According to the specifications of national standard GB 7588, safety Specification for elevator manufacture and installation and safety technical Specification for special equipment TSG T7007-2016, elevator type test rule, in order to meet the requirements of landing door static strength and landing door impact test, the minimum engagement depth allowed by landing door guiding or retaining devices of various landing doors is specified by a definite numerical value.
In the use process, the engagement depth of the door guide shoe and the sill track groove is changed in many cases, for example, because the levelness of the door upper change gear guide rail and the sill is different, the engagement depth of the door guide shoe and the sill track groove is unsatisfied in certain positions when the door is completely opened or closed and the like; because the position of the upper change gear of the landing door is manually adjusted, the whole landing door leaf moves in the vertical direction, so that the engagement depth of the door guide shoe fixed on the door leaf and the door sill track groove does not meet the requirement; the position of the door guide shoe is manually adjusted, so that the engagement depth of the door guide shoe and the door sill rail groove is not satisfactory.
When the engagement depth of the door guide shoe and the door sill rail groove does not meet the requirement, even if external force impact smaller than the allowable requirement or personnel leaning or the like occurs, the safety risk of personnel falling caused by the fact that the door guide shoe falls off the groove easily occurs. Therefore, the measurement of the depth of engagement of the door guide shoe with the door sill rail groove becomes particularly important during routine maintenance and inspection.
The existing door guide shoe engagement depth measurement method has two methods, one method is that the engagement position is marked on the door guide shoe in an engaged state, then the door guide shoe is disassembled and then is measured by a ruler, and the method needs a plurality of people to cooperate, and is time-consuming and labor-consuming; the contact type measurement is carried out by means of special measuring tools, such as patent 201721816131.2 'an elevator landing door guide shoe engagement depth measuring device' and patent 201821039030.3 'an elevator landing door slide block engagement depth measuring device', the measuring process is carried out by means of special measuring tools, the measuring process needs tools to be contacted with the bottom of the door guide shoe, but when the gap between a lower beam of a door leaf and a sill is insufficient, the special measuring tools have insufficient placing space, the measurement is difficult, and sometimes even when the placing space is enough, the measuring devices need to be horizontally adjusted in the measurement, and the like, so that the contact type elevator landing door guide shoe is not convenient.
In the existing sensing technology, the light spot reflection type laser sensor has the capability of detecting microminiature objects, the minimum light spot diameter can be below 1mm, the positioning of the edges of the objects can be realized, and the light spot reflection type laser sensor has the advantages of high precision, small volume and the like; the capacitive grating sensor consists of a sensor module and a reflecting grating, wherein the sensor module is parallel to the reflecting grating, and the distance between the sensor module and the reflecting grating is smaller than 0.2mm. The capacitive grating sensor can convert the mechanical displacement analog quantity of the sensor module and the reflective grating into digital quantity for measurement, wherein the linear capacitive grating sensor is widely applied and is an important electronic measurement element. The capacitive grating sensor has the advantages of simple structure, small volume, high measuring speed, high accuracy and the like.
