Detailed description of the invention
Embodiment 1: as it is shown in figure 1, a kind of handrail elevator security protection system, including a truss, a static bruss 4 and extremely
A few electric power loop disconnecting mechanism 1.Truss includes one and horizontally disposed sets a roof beam in place 21, sets a roof beam in place and 21 fixes with truss.Static bruss 4 is pacified
It is loaded on truss, for removing the electrostatic on elevator.
As in figure 2 it is shown, each electric power loop disconnecting mechanism 1 all includes bearing 11, rotating shaft 12, an at least drive link
13, at least one 14, one switching device 15, comer pieces 16 and at least one jump ring 17 that re-pack is switched.
As it is shown in figure 5, the schematic diagram that Fig. 5 is comer pieces 16 and jump ring 17 mounting structure.Wherein, each comer pieces 16 includes that one is horizontal
Bar and at least two connecting rod.Cross bar is installed on sets a roof beam in place on 21；One end of two of which connecting rod is vertically connected at cross bar
Two ends, each jump ring 17 correspondence is fixed on each connecting rod.
Bearing 11 is fixed on by fixture correspondence sets a roof beam in place 21, and rotating shaft 12 is installed on along elevator stair 3 level run direction
On bearing 11；Rotating shaft 12 is axially fixed at comer pieces 16 by jump ring 17.By jump ring 17 and comer pieces 16 with the use of, it is possible to have
The prevention rotating shaft 12 of effect moves axially so that the axial location of drive link 13 changes.
As it is shown on figure 3, drive link 13 vertically and is perpendicular to rotating shaft 12 and installs, its lower end is fixed in rotating shaft 12, on it
End is positioned at the fishback of handrail elevator or pedal or the lower section of elevator stair 3.
Switch 14 one_to_one corresponding that re-pack to be fixed in rotating shaft 12.Switch re-packs and is provided with a groove 141, the present embodiment on 14
In, the notch of groove 141 is laterally disposed.Groove 141 is V-shaped groove, the groove face transitions smooth of V-shaped groove.Switch contact 151 is placed in recessed
In groove 141.
Switching device 15 is connected to elevator and runs on power control loop.The switch contact 151 of switching device 15 is placed in out
Close re-pack 14 movement travel in, the movement travel described in the present embodiment refers to, when switch re-pack 14 groove 141 along rotating shaft
The radial rotary of 12 and the path that formed is formed.When elevator does not occurs to sink, the switch contact 151 of switching device 15 vertically to
On be placed in groove 141；When elevator occurs to sink, switch re-packs 14 along the radial rotary of rotating shaft 12, now groove 141
Also concomitant rotation, when turning to certain angle, the inner edge of V-shaped groove touches switch contact 151, along with rotating shaft 12 turns further
Dynamic, switch contact 151 detonator circuit open circuit so that whole elevator is out of service.
When being embodied as, electric power loop disconnecting mechanism 1 is placed at elevator entrance, and electric power loop disconnecting mechanism 1 includes three
Drive link 13, is respectively placed in the fishback of handrail elevator and pedal and the lower section of the first step.
The upper end of each drive link 13 from the lower surface of described fishback or pedal or elevator stair 3 have specifically away from
From, its distance range is 5mm ~ 15mm.When less than 5mm, drive link 13 touches fishback or pedal or elevator stair sometimes
3, affect the properly functioning of elevator, when higher than 15mm, elevator degree of sinking is excessive, then can not effectively prevent elevator from sinking and send out
Raw.
In order to ensure safety when elevator sink, rotating shaft 12 is also connected with an angle limiter 18, maximum in the present embodiment
The anglec of rotation is not more than 60 °.When the situation occurring elevator to sink, if in maximum rotation angle range, switching device 15 is also
Have not been able to open circuit effect, then rotating shaft 12 is due to the effect of angle limiter 18, then stop further rotating, now rotate bar
Can use as support bar, prevent elevator stair 3 grade from sinking further.
Embodiment 2, as shown in Figure 4, the present embodiment is in place of the difference of embodiment 1: drive link 13 and vertical direction
Having an angle between the straight line of place, its angular range is more than 0 °, less than 10 °.Owing to drive link 13 is placed in handrail elevator
Below fishback or pedal or elevator stair 3, when the fishback of handrail elevator or pedal or elevator stair 3 occur to sink and touch
During to drive link 13, drive link 13 can be along the radial rotary of rotary shaft.Set between drive link 13 and vertical direction place straight line
Have an angle, be so that sink time produced power, the body of rod direction all along drive link 13 is not passed to, and causes drive link
13 can not be flexibly along the radial rotary of rotary shaft.
It should be pointed out that, for the present invention through absolutely proving, also can have the embodiment of multiple conversion and remodeling,
It is not limited to the specific embodiment of above-mentioned embodiment.Above-described embodiment is as just the explanation of the present invention rather than to this
The restriction of invention.In a word, protection scope of the present invention should include that those are the most apparent
Conversion or replacement and remodeling.
