Background
The guiding and maintaining of the elevator door consists of upper and lower guiding and maintaining devices, the door guide 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 and keep the original design position through the matching of the door guide shoe and the door sill track groove. According to the regulations of national standard GB 7588 Elevator manufacturing and installation safety Specification and Special Equipment safety technical Specification 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 allowable engagement depth of the landing door guiding or holding device of various landing doors is specified by definite numerical values.
In the using process, the meshing depth of the door guide shoe and the groove of the sill rail is changed under many conditions, for example, because the levelness of the door upper change gear guide rail and the sill is different, the meshing depth of the door guide shoe and the groove of the sill rail at certain positions can not meet the requirements when the door is completely opened or closed and the like; the position of the hanging wheel at the upper part of the landing door is manually adjusted, and 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 groove of the sill track can not meet the requirement; because the position of the door guide shoe is manually adjusted, the engagement depth of the door guide shoe and the groove of the sill rail does not meet the requirement.
When the depth of engagement of door guide shoe and sill track recess is unsatisfied with the requirement, even appear to be less than the external force striking that allows the requirement or personnel lean on the situation etc. also take place easily because the door guide shoe takes off the groove and arouses the safety risk that personnel fall. Therefore, the measurement of the engagement depth of the door guide shoe and the door sill rail groove becomes especially important in the routine maintenance and inspection.
The existing method for measuring the engagement depth of the door guide shoe comprises two methods, one is to mark the engagement position on the door guide shoe in the engagement state, and then to measure the engagement depth by using a ruler after the door guide shoe is disassembled, and the method needs to be matched by a plurality of persons and is time-consuming and labor-consuming; one is to rely on a specially-made special measuring tool to perform contact measurement, for example, patent 201721816131.2, "a device for measuring the engagement depth of elevator landing door guide shoes" and patent 201821039030.3 "device for measuring the engagement depth of elevator landing door sliders" both measure through the special measuring tool, the measuring process requires the tool to contact with the bottom of the door guide shoes, but when the gap between the door leaf lower beam and the door sill is not enough, the special measuring tool does not have enough space to place, so that the measurement is difficult, and sometimes, even when the space is enough, the measuring device needs to be horizontally adjusted in the measurement, and the measurement is not convenient enough.
In the existing sensing technology, a light spot reflection type laser sensor has the capability of detecting a micro object, the minimum diameter of a light spot can be below 1mm, the edge of the object can be positioned, and the light spot reflection type laser sensor has the advantages of high precision, small size 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 less than 0.2 mm. The capacitive grating sensor can convert the mechanical displacement analog quantity of the sensor module and the reflecting 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.

The non-contact automatic measuring method of the engagement depth of the elevator door guide shoe according to claim 5, characterized in that the state indicator lamp (107) connected with the main control module (103) in signal transmission is arranged on the upper plane (111) of the horizontal block (1), and comprises a green state indicator lamp for indicating that the measurement is in progress and a red state indicator lamp for indicating that the measurement is finished, wherein the green state indicator lamp is on and continues when the control button (108) is pressed in the step 2), and the red state indicator lamp is on and the green state indicator lamp is off when the main control module (103) locks the numerical value displayed on the data display (106) in the step 3).
7. The non-contact automatic measuring method of the engagement depth of the elevator door guide shoe according to claim 5, characterized in that the two sides of the upper plane (111) of the horizontal block (1) are provided with the center position mark (110) in a matching manner, the connecting line of the center position marks (110) at the two sides is coincident with the corresponding center line of the vertical block (2), and the center position mark (110) is aligned with the center of the door sill rail when the vertical block (2) is inserted into the groove of the door sill rail in the step 1).
8. The non-contact automatic measuring method for the engagement depth of the elevator door guide shoe as claimed in claim 5, wherein the main control module (103) in step 3) sums the displacement data returned by the capacitive grating sensor module (104) and the initial distance value of the engagement measurement, and sends the calculated value to the data display (106) for displaying in real time.
