Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Figure 1, handrail elevator sudden stop photoelectricity inter locking gear of the present invention, for the emergency braking of conventional handrail elevator, comprise pulling force sensor 3, tensile controller (not shown), anchor fitting 6, connect the check band 1 of described pulling force sensor and anchor fitting; Described pulling force sensor 3 is arranged on the spud pile 4 set up outside handrail elevator one end, described tensile controller is connected with pulling force sensor 3, control elevator on/off by its electric signal, described anchor fitting 6 is arranged on the spud pile 4 set up outside the other end of handrail elevator, described check band 1 is in handrail oblique upper, transferred by the pulley 2 arranged and arrange, to adapt to the shape of elevator, ensure parallel with wainscot 5 upper end and handrail, pulley 2 is fixed by strut bar 7.Described strut bar 7 is arranged on described wainscot 5, and is screwed.The present invention is also included in many groups light emitters, the light receiver that check band 1 is vertically installed by staircase side and/or installed in check band 1 lower horizontal, and the light controller be connected with described light receiver; Described tensile controller and light controller adopt "AND" circuit to be connected, and control elevator on/off.Often organize light emitters, light receiver one_to_one corresponding, the spacing distance between two groups is advisable to be less than or equal to 5cm, avoids arm to extend through and does not just in time shut out the light.
Why at many groups light emitters, the light receiver vertically installing by staircase side at check band 1 and/or install in check band 1 lower horizontal, if be because people pulls with hand check band 1 from terraced the walking of elevator, level and vertical light will inevitably be blocked.Whole level to or whole vertical light receiver all adopt OR circuit, namely whole level to or whole vertical levels in any one group or several groups be blocked, then judge " horizontal direction is blocked " or " vertically blocking ".When condition does not allow, only install level to or vertical also passable, but erroneous judgement may be caused; When conditions permit, preferably level and vertical simultaneously installation organize light emitters, light receiver more, level to and vertically between adopt "AND" circuit to connect, namely only have and be all determined with when blocking in the horizontal and vertical direction, overall circuit just sends " blocking " signal, avoids erroneous judgement.
Check band 1 apart from the distance of described handrail according to the average height in area or use the difference of crowd, different horizontal and vertical distances can be adopted, usual vertical direction distance 300 ~ 600mm, horizontal direction distance 200 ~ 400mm, in the most of area of China, comparatively preferred horizontal throw is 300mm, and vertical distance is 500mm.Check band 1, be preferably steel cable, diameter is 2-3mm, and also can adopt nylon rope etc., diameter is arranged as required according to environment for use and intensity etc.
Find with actual measurement according to data, the right hand pulling force of man is about 700N, and woman is approximately 390N.So the break-make threshold value of controller preferably can be set to 300-400N.Consider that the health of old man and part woman is comparatively weak, 350N may be reasonable preferred value, also can adjust according to operation actual conditions.
It is of the present invention that to sketch principle of work of the present invention below in conjunction with accompanying drawing as follows.
Brake system of the present invention is in fact by the co-controlling of two subsystems, and namely strength judges subsystem and blocks judgement subsystem; Strength judges subsystem principle: check band 1 drives described pulling force sensor 3 by when vertical or skew force, and pulling force is converted to electric signal by pulling force sensor 3, then judges whether pulling force exceeds setting value by tensile controller; Block and judge subsystem principle: when nobody pulls check band 1, the light launched of light emitters always receive by light receiver; Stretch out one's hand when pulling check band 1 when there being people, arm to have blocked in many groups light emitters, light receiver the light transmission of a certain group or several groups, and light receiver does not receive light, and now light controller sends " blocking " signal.Strength judges subsystem and blocks to judge that both subsystems adopt "AND" circuit to be connected, and only has when satisfying condition simultaneously, when namely pulling force had not only exceeded setting value, light but also had been blocked, and the just cut-out of control elevator power supply.
When not having emergency situation, check band 1 is static hovers over top outside handrail elevator, and minor cannot touch easily; Light emitters launch light always receive by light receiver.Now, handrail elevator normal continuous runs.
After burst emergency situation, after the adult being in any position in handrail elevator stroke gives the certain vertical or skew force of check band 1, check band 1 drives pulling force sensor 3, and tensile controller judges pulling force size: if value of thrust is no more than setting value, then elevator maintains normal operation; If value of thrust exceedes setting value, then send " exceeding " signal; Meanwhile, the circuit of light receiver, if it is determined that when not having object to block, then elevator maintains normal operation; When judgement level and/or when vertically having object to block, then send " blocking " signal; Tensile controller and light receiver adopt "AND" circuit to be connected, and namely " exceed " when signal occurs with " blocking " signal simultaneously and then disconnect handrail elevator power supply, make handrail elevator out of service, termination accident develops.
