Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model elevator door departs to detect to be protected and alarm device, comprise and depart from fender guard 1, circuit switching 2, circuit switching 2 is fixedly installed on the side of elevator door 4 (can be gate or layer door), and the below of circuit switching 2 arranges and departs from fender guard 1;
Circuit switching 2 can connect alarm device and control unit by signal wire (SW); When circuit switching 2 disconnects, circuit switching 2 sends signal to alarm device and control unit, and elevator is given the alarm, and controls elevator flat bed out of service nearby simultaneously.
As shown in Figure 3, depart from fender guard 1 and comprise the housing 1-1 being fixedly installed on elevator door 4 side, housing 1-1 and cap 1-6 forms shell chamber; Be equipped with a push rod 1-2 in shell chamber, shell chamber is stretched out at the two ends of push rod 1-2; The bottom of push rod 1-2 is embedded with ball 1-5, and ball 1-5 can at end Free-rolling;
The middle part of push rod 1-2 is fixedly installed block, and push rod 1-2 is arranged with push rod spring 1-4, and push rod spring 1-4 is positioned at the top of shell chamber internal stop; The sidepiece of block is provided with telescopic pin 1-3;
As shown in Figure 4, cap 1-6 offers the flexible pin-and-hole 1-7 matched with telescopic pin 1-3;
Telescopic pin 1-3 connects block by spring, relative to its axial motion, thus can realize the radial motion of telescopic pin 1-3 relative to push rod 1-2 when telescopic pin 1-3 is stressed, and telescopic pin 1-3 keeps the trend protruded outward;
In an acute angle between the axis of push rod 1-2 and elevator door 4.
As shown in Figure 5, Figure 6, when the bottom of push rod 1-2 is stressed, push rod 1-2 upward movement contact loop switch 2, make circuit switching 2 close; Now, the block compression push rod spring 1-4 on push rod 1-2 makes it produce elastic potential energy, and telescopic pin 1-3 bounces back in the inside of push rod 1-2;
As shown in Fig. 3, Fig. 7, when the bottom of push rod 1-2 does not stress, push rod spring 1-4 resets, and drives push rod 1-2 move downward and leave circuit switching 2, circuit switching 2 is disconnected; Now, the telescopic pin 1-3 of push rod 1-2 through cap 1-6 flexible pin-and-hole 1-7 and stretch out in flexible pin-and-hole 1-7, push rod 1-2 cannot continue motion.
As shown in Figure 8, circuit switching 2 comprises the switch case 2-1 being fixedly installed on elevator door 4 side, switch case 2-1 internal fixtion is provided with fixed terminal 2-2, one end of fixed terminal 2-2 connects the fixed end of movable terminal 2-3 by rotating shaft, the other end of fixed terminal 2-2 connects the working end of movable terminal 2-3 by spring 2-4;
As shown in Figure 9, when the working end of movable terminal 2-3 is stressed, after the working end Compress Spring 2-4 of movable terminal 2-3, contact fixed terminal 2-2, circuit switching 2 is closed;
As shown in Figure 8, when the working end of movable terminal 2-3 does not stress, spring 2-4 resets, and the working end of movable terminal 2-3 is separated with fixed terminal 2-2, and circuit switching 2 is disconnected.
Circuit switching 2 also can be photo-electric, electromagnetic type, fluid pressure type or other forms of switch, and mode or the device that can realize electric break-make all can use.
As shown in Figure 10, under elevator door 4 is in normal operating condition, elevator door 4 and sill 5 keep plumbness, and due in an acute angle between the axis of push rod 1-2 and elevator door 4, then now the upper surface of push rod 1-2 and sill 5 is in an acute angle;
The ball 1-5 departing from fender guard 1 is butted on the upper surface of sill 5; Elevator door 4 is in switch gate process, and the upper surface contact movement of ball 1-5 and sill 5 produces friction of rolling;
Now, the push rod 1-2 top departing from fender guard 1 is butted on the working end of the movable terminal 2-3 of circuit switching 2, and circuit switching 2 is in closure state all the time.
As shown in figure 11, when elevator door 4 is in disengaged position (namely elevator door 4 is to hoistway side abnormal dip), the push rod 1-2 departing from fender guard 1 deflects relative to sill 5, the lower end of push rod 1-2 is stretched in the sill groove of sill 5, make elevator door 4 cannot continue to tilt, thus the angle of inclination of restriction elevator door 4;
Now because push rod 1-2 loses stressed, push rod spring 1-4 resets, push rod spring 1-4 make push rod 1-2 and on block move downward, the telescopic pin 1-3 of push rod 1-2 stretches out in flexible pin-and-hole 1-7 through the flexible pin-and-hole 1-7 of cap 1-6 in the process moved downward, now cap 1-6 realizes axial location to push rod 1-2, and push rod 1-2 cannot continue motion;
Push rod 1-2 is in the process moved downward, and push rod 1-2 leaves on top the movable terminal 2-3 of circuit switching 2, and circuit switching 2 is disconnected.
Alarm device can be that loudspeaker voice message, buzzing or bright light dodge screen etc., also can be that other can play the alert methods of suggesting effect.Alarm device can access in the more existing electric elementss of elevator, carries out alarm, also can set up separately an elevator alarm unit, only for this monitoring when accident occurs to be different from conventional mode.
When circuit switching 2 closes, control unit controls elevator and normally runs; When circuit switching 2 disconnects, control unit controls elevator flat bed out of service nearby, controls alarm device simultaneously and gives the alarm.Control unit can access in the original control element of elevator, such as station, sedan-chair top.
The utility model is not limited to embodiment discussed above.Above the description of detailed description of the invention is intended to describe and illustrate the technical scheme that the utility model relates to.Based on the utility model enlightenment apparent conversion or substitute also should be considered to fall into protection domain of the present utility model.Above detailed description of the invention is used for disclosing best implementation method of the present utility model, can apply numerous embodiments of the present utility model and multiple alternative to reach the purpose of this utility model to make those of ordinary skill in the art.
