Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 and figure 2 , The present invention provides an escalator or sidewalk protection device, which mainly includes a steel wire rope 1, a detection switch 2, a playing plate 6, a spring 7 and a spring fixing plate 8. The steel wire rope 1 is arranged below the steps or pedals along the length direction of the escalator or moving walk, one end of which is fixedly connected to the escalator or moving walk, and the other end is connected to the playing plate 6. The detection switch 2 It is arranged on the outer side of the steel wire rope 1 and close to the position of the beating plate 6 . In this embodiment, the detection switch 2 is located above the steel wire rope 1 . The escalator or sidewalk protection device also includes a plurality of support rings 4 arranged on the steps or pedals, and the steel wire rope 1 passes t...

Abstract

The invention provides a protective device for an escalator or a side pavement. The protective device comprises a pull rope, a detector switch, an impact plate, an elastic part and an elastic part fixed plate; the pull rope is arranged below stairs or pedals along the length direction of the escalator or the side pavement, one end of the pull rope is fixedly connected onto the escalator or the side pavement, and the other end of the pull rope is connected with the impact plate; the detector switch is arranged on the outer side of the pull rope and is close to the impact plate, the impact plate is rotatably hinged to the outer side of the detector switch, the detector switch is positioned within a rotation radius range, and the impact plate can rotate in the rotation radius range under the pulling action of the pull rope; the elastic part fixed plate is fixedly arranged on the side, which is far away from the detector switch when the impact plate rotates, of the impact plate, the elastic part is connected between the impact plate and the elastic part fixed plate, and the impact plate and the pull rope can be tensioned by the elastic part. The protective device has the advantages that a whole-course detection effect can be realized, the protective device is simple in structure, low in cost, small in occupied space and convenient to maintain and repair, can be mounted flexibly and is not easy to fail.

Description

technical field [0001] The invention relates to a protection device for an escalator or a sidewalk, in particular to a protection device for detecting the subsidence of steps or pedals in the whole process of an escalator or a sidewalk. Background technique [0002] In the prior art, the anti-step or pedal subsidence protection device of the escalator or moving walk can only detect the step or pedal subsidence in a certain area. The detection switch is not only expensive to manufacture, but also troublesome to install, and inconvenient to maintain and overhaul. Contents of the invention [0003] In order to overcome the defects of the prior art, the object of the present invention is to provide a protective device for preventing step or pedal subsidence, which is simple in structure, convenient for installation and maintenance, and can realize full detection of escalators or sidewalks. [0004] In order to achieve the above object, the present invention provides an escala...
