Wherein, tread elements 403 is fixed on the front end of slider bar 402. Slider bar 402 is placed in fixed frame base 401, is slidably connected by guide rail and guider (such as roller) and fixed frame base 401, guide rail and guider guide slider bar 402 to protrude horizontally up and retract fixed frame base 401.
Fixed frame base 401 is fixed with drive motor 404, slider bar 402 is fixed with tooth bar 405 along slider bar 402 telescopic direction, the driving of tooth bar 405 motor 404 driven, promote slider bar 402 to stretch out or retraction fixed frame base 401. It is covered with load-bearing cover plate above fixed frame base 401, stands for passenger.
Wherein, tooth bar 405 may be located at the middle part of slider bar 402, drives electricity, the drive link of 404 is fixed a gear, is meshed with the tooth bar 405 in slider bar 402, drives tooth bar 405, as shown in Figure 4. Or, many driving racks can also be fixed in the laterally-distinct position of slider bar 402, fixed frame base is fixed a drive link, drive link arranges a main transmission node and multiple from transmission node, main transmission node and drive motor are in transmission connection, and are respectively in transmission connection with each driving rack slider bar respectively from transmission node. Thus tooth bar in slider bar 402 can the driving of motor 404 driven, promote slider bar 402 to stretch out or retraction fixed frame base 401.
In order to prevent safety tread from catastrophic failure occurring, pedal is not normally retracted after stretching out, and train normal row sails station into, and both produce to clash into, tracking is handed over train to cause and is damaged or the operation of train is produced harmful effect, adds anti-collision structure in present embodiment on the basis of the above.
Below the anti-collision structure of platform safety tread is specifically introduced, (Fig. 5 is the top view of this safety tread as shown in Figure 5, in order to clearly show that anti-collision structure, Fig. 5 conceals tread elements 403 and fore-end load-bearing cover plate), this anti-collision structure comprises a pair movable push bar, i.e. push rod 501 and push rod 502, is respectively arranged in the two ends of crossbeam 503 on front side of slider bar, insert in beam pipe from crossbeam 503 two ends respectively, carry out linear telescopic along crossbeam and move.
Movable push bar 501 is corresponding respectively with 502 rolls over shape pivoted arm 504 and 505, and two folding shape pivoted arms are distributed laterally side by side.
