Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to Fig. 1; a kind of elevator floor-door safety protection device; comprise bank 1 on layer door that level is arranged on layer door, can along bank 1 relative motion on layer door to open and close the left-hand door plate suspension member 2 of layer door and right door-plate suspension member 3; left-hand door plate suspension member 2 is provided with the left-hand door plate 21 with the motion of left-hand door plate suspension member 2, right door-plate suspension member 3 is provided with the right door-plate 31 moved with right door-plate suspension member 3.Left-hand door plate suspension member 2 and the relative motion of right door-plate suspension member away from or near time, left-hand door plate 21 and right door-plate 31 are just opened or closed layer door.
Sliding sleeve 5, i.e. weight sleeve pipe, vertically extend on fixing left-hand door plate 21.Sliding sleeve 5 has upper end open and lower ending opening, and weight 8 can vertically be arranged in sliding sleeve 5 up and down.Switch 9 relatively weight 8 is fixed on the below of sliding sleeve 5, and switch actuator 6 is fixed on the lower end of weight 8 and extends the lower ending opening of sliding sleeve 5 downwards.In the present embodiment, switch 9 is preferably micro-switch.Steel rope 4 one end connect weight 8 other end from the upper end open of sliding sleeve 5 pass backward extend around guide 10 after horizontal-extending being fixed on right door-plate suspension member 3 again.In the present embodiment, guide 10 is guiding rope sheave, and it is fixedly mounted on left-hand door plate suspension member 2.
The upper end of switch actuator 6 is fixedly connected on weight 8, and its lower end has the horizontal bending part for trigger switch 9, and the width of described horizontal bending part is less than the lower ending opening of sliding sleeve 5.Switch actuator 6 can along with weight 8 up-and-down movement in sliding sleeve 5, and the horizontal bending part of its lower end can free in and out the lower ending opening of sliding sleeve 5.Switch actuator 6 has certain elasticity, can play certain buffer action when weight 8 drops to second place trigger switch 9, weight can be avoided to move and directly pound risk that switch 9 smashes on switch 9.
Wherein, weight 8 has the first control position and the second control position, and when left-hand door plate suspension member 2 and right door-plate suspension member 3 are mutually away from when opening layer door extremely completely, weight 8 is positioned at the first control position, this the first control position is positioned at the top of sliding sleeve 5, and now switch actuator 6 is away from switch 9.When left-hand door plate suspension member 2 and right door-plate suspension member 3 close to each other to close completely time, namely when elevator door is closed completely, weight 8 is positioned at the second control position, and this second control position is positioned at the bottom of sliding sleeve 5, and now switch actuator 6 stretches out just trigger switch 9 downwards from the lower ending opening of sliding sleeve 5.Therefore, only when left-hand door plate suspension member 2 and right door-plate suspension member 3 are closed completely, when weight 8 automatically drops to the second control position under the effect of self gravitation from sliding sleeve 5, switch actuator 6 ability trigger switch 9, after switch 9 is triggered, elevator just allows startup optimization.
When left-hand door plate suspension member 2 and right door-plate suspension member 3 mutually away from time, when namely elevator door is opened, weight 8 is from the second control position upward movement under the pulling of steel rope 4, and switch actuator 6 departs from switch 9, and switch is not triggered, and elevator No starting runs.
When left-hand door plate suspension member 2 and right door-plate suspension member 3 close to each other to not exclusively close time, namely when elevator door is not closed completely, weight 8 is between the first control position and the second control position, and now switch actuator 6 also fails trigger switch 9, and elevator No starting runs.
When left-hand door plate suspension member 2 and right door-plate suspension member 3 close to each other to close completely time, namely when elevator door is closed completely, if when weight 8 cannot drop to the second control position because some other reasons causes decline process in sliding sleeve 5 to be stuck, switch 9 can not be triggered, elevator No starting runs.Only eliminate elevator faults reason, enable weight 8 move to the second control position smoothly when elevator door is closed completely, switch 9 is triggered, just run the normal startup optimization of elevator.
Wherein, in another embodiment, sliding sleeve 5 also can be fixedly mounted on right door-plate 31, and switch 9 is also arranged on right door-plate 31.Correspondingly, one end of steel rope 4 needs to be fixedly connected on left-hand door plate suspension member 2, and guide 10 is arranged on right door-plate suspension member 3.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
