Description
Technical field
Elevator colored light safety device belongs to the elevator safety field, be specifically related to a kind of before Elevator landing the elevator car safety of emission colored light.
Background technology
Under normal circumstances due to layer door locking apparatus, lift car not during arrival floor elevator door be locking, prevent accident from crashing into elevator and have an accident, but when elevator is in maintenance or the inefficacy of layer door locking apparatus, not arrival floor of car just might occur, but the situation of floor elevator door opening, at this time terraced people causes casualty accident with regard to easily crashing into elevator, simultaneously owing to lacking alarming device, some people is reliable custom on elevator door when waiting ladder, and falling accident also easily occurs for this.Existing elevator alarming device complex structure is installed very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of elevator colored light safety device simple in structure is provided.
The technical scheme that its technical matters that solves the utility model adopts is: this elevator colored light safety device, it is characterized in that: comprise flip flop equipment and colored light sources, flip flop equipment is arranged on the elevator wall of lift car and every floor, colored light sources is arranged on every layer of elevator door doorway, is connected by wire between flip flop equipment and colored light sources.
described flip flop equipment comprises the touching piece that is fixed on the lift car lateral surface and is arranged on the interior touching bar of elevator of every floor, in the middle of the touching bar, inclined to one side rear is fixed end, two ends are free end, fixed end is fixed on the axle of fixed frame side frame by bearing, before the touching bar, free end vertically is positioned at the below of touching piece, after the touching bar, free end is positioned in the middle of two switches on the fixed frame upper and lower side frame, touching bar and shaft connection place are provided with retracing spring, the touching bar swings up and down around axle under the effect of touching piece, cause the touching bar after the free end closing switch, thereby close colored light sources.
Described two switches are the Automatic-reset normally closed switch that is in series.
Described touching piece is rectangular blocks, and the two ends, up and down are arc, and arc reduces to touch the friction force between bar and touching piece, and the length on touching block length limit guarantees to close colored light sources with to touch the maximum normal distance that bar swings up and down isometric before elevator cabin flat level.
Described flip flop equipment is comprised of induction pieces and approach switch, and induction pieces is fixed on the lift car lateral surface, and approach switch is fixed in the elevator of every floor, and approach switch is normally closed.
Compared with prior art, the beneficial effect that has of elevator colored light safety device of the present utility model is:
1) simple in structure: the utility model integral structure is simple, and is easy for installation;
2) reliable in action: the flip flop equipment reliable in action that the utility model adopts, maintenance rate is low;
3) length on touching block length limit is isometric with the maximum normal distance that the touching bar swings up and down, and can guarantee to close colored light sources before elevator cabin flat level.
Description of drawings
Fig. 1 is the structural representation of touching piece, touching bar, switch and fixed frame.
Fig. 2 is the schematic diagram of sensor block and approach switch.
Wherein: 1, lift car 2, touching piece 3, touching bar 4, bearing 5, retracing spring 6, axle 7, switch 8, colored light sources 9, fixed frame 10, approach switch 11, induction pieces.
The specific embodiment
Fig. 1 is the most preferred embodiment of the utility model elevator colored light safety device, is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1: elevator colored light safety device comprises lift car 1, touching piece 2, touching bar 3, bearing 4, retracing spring 5, axle 6, switch 7, colored light sources 8 and fixed frame 9.
Touching piece 2 is fixed on lift car 1 lateral surface, touching piece 2 is rectangular blocks, the length on touching piece 2 long limits is isometric with the maximum normal distance that touching bar 3 swings up and down, guarantee to close colored light sources 8 before lift car 1 flat bed, touching piece 2 is circular arc with the two ends up and down that touching bar 3 contacts, and reduces to touch the resistance between piece 2 and touching bar 3.
Principle of work and working process are as follows: lift car 1 is not when This floor, the colored light sources 8 emission colored lights on This floor layer doorway produce warning function, terraced people is waited in prompting and elevator door keeps suitable safety distance, when lift car 1 arrives, the touching piece 2 front free ends of touching touching bar 3, touching bar 3 rotates around axle 6, at the rear free end touching of level position touching bar 3 switch 7, switch 7 disconnects, and this moment, colored light sources 8 circuits disconnected, and colored light disappears.After lift car 1 left, touching bar 3 was got back to level attitude under the effect of retracing spring 5, switch 7 closures, and colored light sources 8 is launched colored light again.
With reference to accompanying drawing 2: elevator colored light safety device, comprise induction pieces 11, approach switch 10 and colored light sources 8, colored light sources 8 is arranged on every layer of elevator door doorway, induction pieces 11 is fixed on lift car 1 lateral surface, approach switch 10 is fixed in the elevator of every floor, approach switch 10 is normally closed, and approach switch 10 is connected with colored light sources 8 by wire.
