Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, the present embodiment one prevents car accidental movement fender guard, comprises two parts composition, and one is mounted in the link plate 1, two on a layer position guide rail 2, and the bearing pin being fixed in car frame upper beam 10 combines as latch.
Wherein, link plate 1 is fixed on guide rail with 8 binding bolts of two rows, and a side of link plate 1 is provided with long spacing hole, and the length of spacing hole is 300mm.
The bearing pin combination of using as latch is installed along car frame upper beam 10, comprises U-shaped support 3, safety detection switch fixed mount, push electric magnet fixed mount.Bearing pin 5 passes support 3 just to link plate 1 spacing hole's midway location, taking the accurate stop position of car as reference standard.Be arranged on the bearing pin 5 of support 3 and be set with retracing spring 4, the other end of bearing pin is connected with actuating device, and actuating device comprises safety detection switch 6, push electric magnet 9.It is 7 fixing to be that the other end of bearing pin 5 and switch re-pack, and this attachment point has been brought in by one of connecting screw rod 8, and the interlude of connecting screw rod 8 coordinates with the pilot hole on safety detection switch fixed mount, with the stability that ensures that connecting screw rod 8 moves.
Safety detection switch 6 is provided with contact pinch roller, as shown in Figure 3, switch 7 plate profile structures with the moulding of many flangings that re-pack, one of them face is provided with and the groove station that contacts pinch roller cooperation, the working condition of this groove station is: when contact pinch roller is positioned at groove station, the original length state of retracing spring 4 in loosening, push electric magnet 9 is in off-position, and safety detection switch 6 is in running order; And in the time that contact pinch roller departs from groove station, push electric magnet 9 is in "on" position, safety detection switch 6 is in off-state.The tail end of connecting screw rod 8 and push electric magnet 9 are fixing.
Safety detection switch 6, push electric magnet 9 are all connected with apparatus for controlling elevator.
Course of action is as follows:
One, when elevator is under normal operating condition, from running state transfers ramp to stop to and opens the door, door-closing in-place on-off signal, on-off signal, door lock signal disconnect, and door district signal is effective.Now, this device sends and stretches out bearing pin 5 instructions, bearing pin 5 is inserted in the link plate spacing hole in flat bed region, the safety detection switch 6 of monitoring bearing pin 5 disconnects, in case locking system provides operating instruction, limited the moving section under the non-driven state of car simultaneously, upper and lower be aggregated in 300mm within.After door is closed, door-closing in-place signal, door lock signal action, push electric magnet 9 power-off, are resetted bearing pin 5 by retracing spring 4, and safety detection switch allows elevator to start operation simultaneously.
Two, elevator is in the time that opening the door of normal condition received guests, and bearing pin 5 is all the time in being inserted in link plate 1 spacing hole's state, only has when door lock closure and door-closing in-place signal are when effective, just makes push electric magnet 9 power-off and ensures that bearing pin 5 resets.In the time again opening the door, bearing pin 5 inserts again.
Three, open the door again story-leveling function and advance door opening function of elevator, action protection can be selected.If selected more than when protection need consider that link plate spacing hole length should be greater than the twice of the advance door opening distance of control system and the flat bed operating distance that opens the door again, when preventing this device action with advance door opening and interfering with each other of moving of flat bed again.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any structure after simple transformation of the present utility model is all belonged to protection domain of the present utility model.
