Abstract
Description
Technical Field
[0001] The invention relates to the technical field of escalator gap measurement, and in particular to a method for measuring gaps between all steps and apron plates. Background Art
[0002] During the inspection of escalators, it is necessary to measure the gap between the edge of the step and the apron plate. If the gap is too large, it is easy for passengers' clothes or shoes to get stuck in the gap and cause harm to the passengers. GB16899-2011 "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walkways" stipulates: "The apron plates of escalators or moving walkways are set on both sides of the steps, pedals or belts. The horizontal gap on any side should not be greater than 4mm, and the total gap measured at the symmetrical positions on both sides should not be greater than 7mm." The steps and apron plates of the escalators we commonly see in daily life are composed of several steps. There are generally dozens of steps. The steps of an escalator with a high lifting height may exceed one hundred. The apron plate is also assembled from several stainless steel plates. Due to installation accuracy issues, the edge of each step is not on the same horizontal plane, and the same is true for the apron plate. Therefore, the gaps between different steps and apron plates may be different at different positions. The common measurement method now is to measure the gap between some steps and the apron plate, and then judge whether the gap between other steps and the apron plate is qualified based on experience. It can only be qualitative but not quantitative, is greatly affected by human factors, and has low accuracy.

[0037] The control device 3 includes a processor 31, a storage unit 32, and a transmission module 33;
[0038] The spring self-restoring displacement sensor 11 and the line laser measuring instrument 21 are both connected to the processor 31 for communication; the storage unit 32 is connected to the processor 31 for storing the measured data;
[0039] The transmission module 33 is connected to the processor 31 for transmitting the measured data to the client; the client includes a mobile phone and a computer; the transmission module 33 includes a remote communication module 331 and a Bluetooth transmission module 332;
[0040] The remote communication module 331 supports 4G full network version, supports China Mobile / China Unicom / China Telecom cards, and is used to transmit the data measured on site to the client in real time.
[0041] In an embodiment of the present invention, each telescopic plate 13 is provided with a baffle groove 131 ; the baffle 132 is movably received in the corresponding baffle groove 131 .
[0042] In one embodiment of the present invention, the fixed plate 12 is provided with a telescopic slot 14, and one end of the two telescopic plates 13 is movably received in the telescopic slots 14 at both ends of the fixed plate 12;
[0043] In one embodiment of the present invention, the probe rod measuring device 1 also includes two telescopic rods 15, both of which are connected to the fixed plate 12, and the output end of each telescopic rod 15 is fixedly connected to a telescopic plate 13; the telescopic rod 15 is used to drive the corresponding telescopic plate 13 to move relative to the fixed plate 12.
[0044] In one embodiment of the present invention, the detection rod 23 and the telescopic rod 15 are both electric telescopic rods.
[0045] In one embodiment of the present invention, each detection rod 23 is fixedly provided with a tilt sensor 231;
[0046] The detection rod 23 , the telescopic rod 15 and the tilt sensor 231 are all connected to the processor 31 for communication.
[0047] In one embodiment of the present invention, a laser emitter 16 is disposed on the lower surface of each telescopic plate 13 ; the laser emitted by the laser emitter 16 is coplanar with the side surface of the baffle 132 contacting the measuring end of the spring self-restoring displacement sensor 11 .
[0048] When the device for measuring the gap between all steps and the apron plates is used, the fixed plate 12 is placed on the first step (i.e., step No. 1) at the entrance of the escalator 4, and the corresponding telescopic plate 13 is driven by the telescopic rod 15 to move relative to the fixed plate 12 to both sides of the escalator, so that the measuring ends of the two spring self-restoring displacement sensors 11 are respectively in contact with the apron plates on both sides of the escalator; the inspector then compresses the measuring end of the spring self-restoring displacement sensor 11 by hand, so that the measuring end of the spring self-restoring displacement sensor 11 moves to the side of the corresponding baffle groove 131, and inserts the baffle 132 into the baffle groove 131, so that the spring self-restoring displacement sensor 11 can be moved to the side of the corresponding baffle groove 131. The measuring end of the restoring displacement sensor 11 contacts the side of the baffle 132; the spring self-restoring displacement sensor 11 of the inspector is zeroed; at this time, the laser emitted by the laser emitter 16, the edge of the escalator step, and the side of the baffle 132 contacted by the measuring end of the spring self-restoring displacement sensor 11 are coplanar; after the zeroing is completed, the baffle 132 is pulled out from the corresponding baffle groove 131, so that the measuring ends of the two spring self-restoring displacement sensors 11 are in contact with the corresponding apron plates again; the distance data detected by the two spring self-restoring displacement sensors 11 is the distance data of the gap on both sides of the step.
[0049] The two laser measuring devices 2 are respectively adsorbed on the inner side of the apron plate at the top of the first escalator by the suction cup 22, and the length of the detection rod 23 is adjusted so that the line laser measuring instrument 21 is located just above the gap between the apron plate and the first step.
[0050] The escalator is started to drive the probe measuring device 1 to move with the escalator, and the spring self-restoring displacement sensor 11 is used to measure the gaps on both sides of the steps;
[0051] The spring self-restoring displacement sensor 11 located on the left side of the escalator detects that the gap of the first escalator is X11L;
[0052] The spring self-restoring displacement sensor 11 located on the right side of the escalator detects the gap of the first escalator as X11R
[0053] Then the gap on the left side of the escalator detected by the spring self-restoring displacement sensor 11 is: X11L...X1NL; the gap on the right side is X11R...X1NR;
[0054] Use a laser measuring device 2 to measure the gap on both sides of the step at the first step of the escalator;
[0055] The left gap detected by the laser measuring device 2 is: X11L...XM1L; the right gap detected by the laser measuring device 2 is X11R...XM1R;
[0056] X21L-X11L=△X2L;
[0057] X21R-X11R=△X2R;
[0058] X31L-X11L=△X3L;
[0059] X31R-X11R=△X3R;
[0060] △XML=XM1L-X11L; △XMR=XM1R-X11R
[0061] Then XMNL=X1NL+△XML, XMNR=X1NR+△XMR.
[0062] X1 NL represents the distance of the left gap from step 1 to step N, X1 NR represents the distance of the right gap from step 1 to step N, XM1L represents the distance of the left gap from step M to step 1, and XM1R represents the distance of the right gap from step M to step 1; then XMNL is the distance of the left gap when step M runs to step N, and XMNR is the distance of the right gap when step M runs to step N.
[0063] The national standard stipulates that the horizontal gap on any side should not be greater than 4mm, and the total gap measured at the symmetrical positions on both sides should not be greater than 7mm.
[0064] Then XMNL=X1 NL+△XML≥4mm, XMNR=X1 NR+△XMR≥4mm, or XMNL+XMNR≥7mm, and the gap distance when step N runs to step M is unqualified.
