Collapse-preventive sensing device for escalator

Abstract

The invention relates to a collapse-preventive sensing device for an escalator. The device comprises a cover plate, and a support for mounting the cover plate, wherein sensing blocks are arranged below the cover plate, and the sensing blocks are correspondingly positioned at the left side and the right side of the cover plate; each sensing block is connected to a telescoping arm which is used forpushing each sensing block to leftwards and rightwards translate; one end of each telescoping arm is fixedly connected to the support, and the other endo of each telescoping arm is provided with a propping part; a mounting seat for mounting each sensing block is arranged on each propping part; the mounting seats are pushed by the propping parts to prop the cover plate through the sensing blocks; apressure sensor is arranged between each mounting seat and the corresponding sensing block; the mounting seats are connected to protecting mechanisms, and the protecting mechanisms form collapse preventing layers below the cover plate while the two mounting seats are close to each other. The device is capable of detecting in advance when the escalator does not run, so that the accident can be effectively prevented; the whole device is simple in structure, and safe and stable to move, and can be repeatedly used for a long term; the safety protecting performance of the escalator is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an escalator anti-collapse sensing device. Background technique [0002] Escalators are now widely used in shopping malls, railway stations and other public places. While escalators bring convenience to people, it is gradually found that using escalators also brings a lot of trouble or causes heavy casualties. In the process of using escalators , Sometimes the upper and lower covers of the escalator fail, but they are still in use and have not been found. If you don't realize that the problem exists, you still use it, which often causes great harm. When the device for fixing the upper and lower cover plates of the escalator becomes loose or does not work at all, people step on it without knowing it, and the cover plate collapses, causing an accident. [0003] For example: the Chinese utility model patent with the application number 201720590105.6 discloses an anti-collapse de...

[0002] Escalators are now widely used in shopping malls, railway stations and other public places. While escalators bring convenience to people, it is gradually found that using escalators also brings a lot of trouble or causes heavy casualties. In the process of using escalators , Sometimes the upper and lower covers of the escalator are faulty, and they are still in use, and have not been found

It is still used without realizing the existence of the problem, which often causes great harm

When the device for fixing the upper and lower cover plates of the escalator is loose or cannot work normally at all, people step on it without knowing it, and the cover plate collapses, causing accidents

[0003] For example: the Chinese utility model patent with the application number 201720590105.6 discloses an anti-collapse device for the entrance and exit of an escalator, which includes the main frame of the escalator and the pedal fixed at the entrance and exit of the main frame. The bottom of the pedal is fixed with a locking unit. The tightening unit includes a first locking plate arranged on the left edge of the pedal and a second locking plate arranged on the right edge of the pedal, the first locking plate is provided with a first locking hole, and the second locking plate is provided with a There is a second locking hole, the first locking hole is provided with a first locking rod that cooperates with sliding, the second locking hole is provided with a second locking rod that cooperates with sliding, and the first locking rod is hinged with a second locking rod. One pull rod, the second lock rod is hinged by the second pull rod, the first pull rod and the second pull rod are cross-hinged, and are driven by the driver. The disadvantage is that the device cannot actively detect whether there is a problem with the cover plate, and it can only Functions when the passenger walks on the cover
