Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1 to Figure 3, it is the structural representation of a kind of laser type elevator door of the utility model safety device embodiment, comprise pin 1, bar cover 2 and spring 3, bar cover 2 is embedded in elevator door 4 bodies, the opening of bar cover 2 is positioned in the closed sides of elevator door 4, the bottom of bar cover 2 is provided with spring 3, when after pin 1 indentation bar cover 2, the root Compress Spring 3 of pin 1, the head of pin 1 is positioned at bar cover opening part by electromagnetism pin tongue 5, the unlatching loop of electromagnetism pin tongue 5 and the triggering loop of laser induced switch 6 electric-linked, when laser induced switch detects that personnel are extremely close, electromagnetism pin tongue 5 is retracted, namely pin launches, this link also can link with annunciator 10, further raising warning function.Electromagnetism pin tongue 5 has tapered ramp and can improve compressive force to spring when pin resets.
In order to ensure that spring 3 successfully ejects and resets, spring housing is contained on guidepost 7, and the end of guidepost has longer boot segment, to ensure that spring is in the right direction by what compress, so both ensure the reliable injection of pin, when can also ensure that pin is retracted quick and precisely, reduce unnecessary resistance.
See shown in Fig. 4, Fig. 5, be the evidence solution of pin 1 itself, one is by being provided with fluorescent paint striped 8 on the shaft of pin 1, makes dark situations lower stop lever more eye-catching.Another is by being provided with reflecting coating 9 on the shaft of pin 1, reaches this object.In some use occasions, fluorescent paint 8 and reflecting coating 9 also can combinationally use, to produce a desired effect.
See Fig. 6, it is the structural representation of the utility model safety guard embodiment, comprise fence 11, retracing spring 13, clump weight 14, motor reel 15 and laser position sensors 12, fence 11 is between the slideway 21 of two levels, one end of fence 11 is walked around pulley 16 by main push-towing rope rope 19 and is connected with clump weight 14, motor reel 15 is connected with clump weight 14 by auxiliary hawser 18, retracing spring 13 is provided with between fence 11 and fixed connecting base 20, the laser position sensors 12 detecting elevator door position is divided into Shang Yanchu and Xia Yanchu of elevator door 4, controller 17 is connected by wire with laser position sensors 12 with motor reel 15 respectively, form control loop.
In order to realize the accurate control of fence 11 miles of relative movement, on motor reel 15, the number of turns of auxiliary hawser 18 is mated with fence 11 miles of relative movement, can reduce spatial volume and the cost of device.In order to improve the precision of control further, the opening travel limit place of fence 11 or arrange limit switch, avoids fence to open not in place, scratching passenger-in-elevator.
The working process of safety guard is: lift car from bottom to top time, first touch lower laser position sensors, sensor is to controller energizing signal, and controller controls motor reel and transfers clump weight, traction fence is opened, when lift car continues upwards, when touching laser position sensors, trigger controller controls motor pull-up clump weight, fence is closed, even if elevator door mal is opened, owing to having fence horizontal stroke in the presence of, people can not enter easily; Lift car from top to bottom time, first laser position sensors is touched, trigger controller controls motor and transfers clump weight, open fence, car continues, to touch lower laser position sensors downwards, and trigger controller controls motor pull-up clump weight, close fence, can prevent people from entering elevator equally.When keeping in repair or extraordinary circumstances need people to enter elevator, fence can be striden across and enter.When dangerous situations such as power failure, fire alarms, control fence by backup power and be automatically in closed condition.
