Abstract
The utility model relates to a kind of elevator, particularly relates to a kind of emergency staircase.Warning box is arranged on top margin and the base of doorframe, when object is clamped by gate, along with the startup car of elevator and floor produce relative displacement.When in the bottom of car or top and clipped object place floor interleaved processes, caught object applies pressure to being exposed to outer blend stop at aperture position, make blend stop toward pressing down, when blend stop encounters the contact limit switch be arranged on base, trigger controller controls elevator emergency and stops.Warning box actv. compensate for the deficiency of light curtain and safety edge, controls elevator emergency stop when light curtain and safety edge all lost efficacy, and Accident prevention occurs.
Description
Technical field
The utility model relates to a kind of elevator, particularly relates to a kind of emergency staircase.
Background technology
Lift car between gate, generally install light curtain or safety edge prevents the accident by mistake passenger or object crushed from occurring.But light curtain and safety edge all exist certain blind area, may can't detect for leading the cord of dog, the trick of child and clear glass etc. and cause accident.
Summary of the invention
The purpose of this utility model is a kind of emergency staircase provided to solve the problem.
For achieving the above object, the utility model provides a kind of emergency staircase.Comprise car and controller, described car arranges doorframe and gate.It is characterized in that: also comprise and be separately positioned on the top margin of described doorframe and the warning box on base.Described warning box comprises shell, the base be fixedly connected with described doorframe and is arranged on blend stop and the elastomeric element of described warning box inside.Shell is provided with opening in described gate folding position; Described base is provided with contact limit switch, and described contact limit switch is electrically connected with described controller; Described blend stop is parallel with described base, and described elastomeric element is arranged between described blend stop and described base, is fixedly connected with described blend stop and described base.Described warning box is arranged on top margin and the base of described doorframe, and when object is clamped by described gate, the described car of the startup along with elevator and floor produce relative displacement.When in the bottom of car or top and clipped object place floor interleaved processes, caught object applies pressure to being exposed to outer described blend stop at described aperture position, make described blend stop toward pressing down, when described blend stop encounters the described contact limit switch be arranged on described base, trigger described controller control elevator emergency and stop.Outside the part that described blend stop is only positioned at described gate folding position by the design of described opening is exposed to, avoid the false triggering of described warning box.And the Integral design of described warning box makes the installation of described warning box, maintenance and replacing all very convenient.
As preferably, the side of described warning box arranges guide rail, the two ends sliding block joint of described guide rail and described blend stop.Described blend stop moves along described guide rail at lower planes after stressed.
As preferably, described elastomeric element is spring.After stressed disappearance, blend stop returns to normal position.
As preferably, described contact limit switch is arranged on position relative with described opening on base.Described contact limit switch is arranged on the below of the force part of described blend stop, more directly effectively.
As preferably, described gate is provided with light curtain.Described light curtain is as the first line of defence of anti-pinch, and described warning box is as the second defence line of anti-pinch.When described light curtain lost efficacy, described annunciator can also control elevator emergency at crucial moment and stop, the incidence of reduction accident greatly.
As preferably, the thickness of described warning box is 2 ~ 3cm.
As preferably, the width of described warning box is 3 ~ 6cm.
As preferably, the width of described opening is 3 ~ 10cm.
The present invention has following beneficial effect: described warning box is arranged on top margin and the base of described doorframe, and when object is clamped by described gate, the described car of the startup along with elevator and floor produce relative displacement.When in the bottom of car or top and clipped object place floor interleaved processes, caught object applies pressure to being exposed to outer described blend stop at described aperture position, make described blend stop toward pressing down, when described blend stop encounters the described contact limit switch be arranged on described base, trigger described controller control elevator emergency and stop.Described warning box actv. compensate for the deficiency of light curtain and safety edge, controls elevator emergency stop when light curtain and safety edge all lost efficacy, and Accident prevention occurs.
Accompanying drawing explanation
Fig. 1 is a kind of side-looking constructional drawing of emergency staircase.
Fig. 2 is the structural representation of warning box.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail.As shown in Figure 1, a kind of emergency staircase, comprises car and controller.Car arranges doorframe 1, gate 2 and is separately positioned on the top margin of doorframe 1 and the warning box 3 on base.The thickness of warning box is 2.5cm, and width is 5cm.
As shown in Figure 2, warning box 3 comprises shell 31, the base 32 be fixedly connected with doorframe, the blend stop 33 being arranged on warning box 3 inside and elastomeric element 34.Shell 31 is provided with in gate 2 folding position the opening 311 that width is 8cm.The position that base 32 is relative with opening 311 is provided with contact limit switch 321, and contact limit switch 321 is electrically connected with controller.Blend stop 33 is parallel with base 32.Elastomeric element 34 is spring, is arranged between blend stop 33 and base 32, is fixedly connected with blend stop 33 and base 32.The side of warning box 3 arranges guide rail 35, the two ends sliding block joint of guide rail 35 and blend stop 33.
Embodiments of the present invention working process is as follows:
Warning box is arranged on top margin and the base of doorframe, when object is clamped by gate, along with the startup car of elevator and floor produce relative displacement.When in the bottom of car or top and clipped object place floor interleaved processes, caught object applies pressure to being exposed to outer blend stop at aperture position, make blend stop toward pressing down, when blend stop encounters the contact limit switch be arranged on base, trigger controller controls elevator emergency and stops.Outside the part that blend stop is only positioned at gate folding position by the design of opening is exposed to, avoid the false triggering of warning box.And the Integral design of warning box makes the installation of warning box, maintenance and replacing all very convenient.
Although describe embodiments of the present invention by reference to the accompanying drawings, those of ordinary skill in the art can make various distortion or amendment within the scope of the appended claims.
