Specific embodiment
The present invention is further explained in the light of specific embodiments.
As shown in Figures 1 to 6, automatic staircase comb plate safeguard construction provided by the present embodiment, including movable fishback
1, the leading-edge pedal 2 that is connected with the rear end of movable fishback 1, shaft 3, switch block 4, limit switch 5, reset spring 8 and
Spring block 9, movable fishback 1 are fixedly arranged at the front end with a lobate comb structure of row's class, and the step pedal of itself and escalator
The tooth socket of (being not drawn into figure) is meshed, and the rear end of movable fishback 1 is connect with the front end of leading-edge pedal 2 by shaft 3, and living
The connecting end surface of the rear end of dynamic fishback 1 forms arcuate structure, and the connecting end surface of the front end of leading-edge pedal 2 is formed and movable comb teeth
The groove structure that the arcuate structure of plate 1 is meshed often falls into various foreign matters on step pedal, when foreign matter is stuck in movable comb tooth
When between plate 1 and step pedal, the front end of movable fishback 1 can be quickly flipped up and certain angle of facing upward, and improves whole
A safeguard construction to the response sensitivity of abnormality, and movable fishback 1 in switching process the arcuate structure of its rear end with
The surface of groove structure is bonded always, prevents other foreign matters from falling into the junction of its rear end；Leading-edge pedal 2 is equipped with screw hole
6, for fixing and guaranteeing itself and ground level, upper surface is formed with non-slip groove 7；Movable fishback shape at connection shaft 3
At there is mounting groove, switch block 4, limit switch 5 and reset spring 8 are mounted in the mounting groove, and switch block 4 and shaft 3 connect
It connects, can be kept fixed during movable fishback is flipped up and not rotate, limit switch 5 is set to the upper of switch block 4
Side, and be located at the inside upper surface of mounting groove of movable fishback 1, and pass through conducting wire (being not drawn into figure) and escalator
The safety return circuit of control escalator start and stop, the wiring of these conducting wires are formed into and out of emergency stop switch (being not drawn into the figure) series connection at end
On movable 1 inside of fishback and the surface of entire safeguard construction, the regularity and safety of entire circuit wiring ensure that,
Spring block 9 is set on the arcuate structure of movable fishback 1 and is located at the top of reset spring 8, the bottom of spring block 8 and peace
The inside upper surface of tankage flushes, and be collectively formed on the bottom of spring block 8 and the inside upper surface of mounting groove one with
The identical circular groove of 8 diameter of reset spring, one end of reset spring 8 are built in the outer arc of switch block 4 with semi-surrounding structure
In the formed cylindrical void in lower end of place and groove structure, and it is inconsistent with the bottom of cylindrical void, and the other end contradicts
And extend into above-mentioned circular groove, movable fishback 1 compresses reset spring 8 when being flipped up, circular groove and circle
Cylindrical void can limit the motion profile of reset spring 8, guarantee reset spring 8 in deformation without departing from working normally track,
When foreign matter situation makes movable fishback 1 face upward certain angle, limit switch 5 is moved downward in turn by the drive of movable fishback 1
Switch block 4 is touched, the switch state of limit switch 5 changes, and the starting emergency stop switch of real-time, so that safety is returned
Road is disconnected, and escalator is out of service at once, and after escalator has been excluded failure, movable fishback 1 is opened in reset spring 8
Rapid reset under the action of power can rerun escalator.
The examples of implementation of the above are only the preferred embodiments of the invention, and implementation model of the invention is not limited with this
It encloses, therefore all shapes according to the present invention, changes made by principle, should all be included within the scope of protection of the present invention.
