Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of folding arm in the utility model;
Fig. 2 is the structural representation of automatic safety device of the present utility model under folding arm folded state;
Fig. 3 is the structural representation of automatic safety device of the present utility model under folding arm expansion process state;
Fig. 4 is the structural representation of automatic safety device of the present utility model under folding arm deployed condition.
Detailed description of the invention
As shown in Figures 1 to 4, the passenger of preventing of the present utility model crashes into the automatic safety device of elevator hoistways, comprises direct drive type electro magnet 1, stops plate 2 and two folding arms 3.Two folding arms 3 are arranged in parallel, their both ends that fixed end is hingedly mounted on the top of hoistway door 4 respectively, movable end is separately fixed at obstruction plate 2.
Wherein, folding arm 3 comprises the first to the 3rd support arm 301,302,303 and is provided with first, second torque spring 304,305 of buffer gear, one end of first support arm 301 is hingedly mounted on the top of hoistway door 4 as the fixed end of folding arm 3, first torque spring 304 is fixedly connected between the other end of the first support arm 301 and one end of the second support arm 302, first torque spring 304 is fixedly connected between the other end of the second support arm 302 and one end of the 3rd support arm 303, and the other end of the 3rd support arm 303 is as the movable end of folding arm 3.
Obstruction plate 2 of the present utility model to be positioned at above hoistway door 4 and under the deployed condition of folding arm 3, to be positioned at the front of hoistway door 4 under the folded state of folding arm 3, the iron core 101 of direct drive type electro magnet 1 stretches out and can retract under the "on" position of direct drive type electro magnet 1 under the off-position of direct drive type electro magnet 1, and the installation site of direct drive type electro magnet 1 can make iron core 101 contact of stretching out to stop on plate 2 and to make folding arm 3 remain on folded state by acting on the power stopped on plate 2.
When automatic safety device of the present utility model drops into application, the power on/off state of direct drive type electro magnet 1 can be controlled by two sensors.Whether one of them sensor is opened for the hoistway door 4 detecting this automatic safety device place layer, and whether another sensor is stopped at this automatic safety device place layer for detecting lift car.Therefore, two sensors can control direct drive type electro magnet 1 and open and lift car is not energized when this automatic safety device place layer is stopped at hoistway door 4, hoistway door et out of order can be judged thus, the iron core 101 of direct drive type electro magnet 1 is retracted because of energising, folding arm 3 is made no longer to start to launch (see Fig. 3) by iron core 101 application force of direct drive type electro magnet 1 by stopping plate 2, and finally make to stop the front (see Fig. 4) that plate 2 is positioned at hoistway door 4 after folding arm 3 launches completely, thus play the effect of warning preventing personnel to be strayed into elevator when hoistway door et out of order, actv. avoids personnel and crashes into hoistway, reduce the occurrence probability of casualty accident.Otherwise; two sensors control the power-off when elevator normally runs of direct drive type electro magnet 1; thus direct drive type electro magnet 1 iron core 101 contact of stretching out to stop on plate 2 and to make folding arm 3 remain on folded state by acting on the power stopped on plate 2, automatic safety device of the present utility model is being hidden in the wall of hoistway door 4 top (see Fig. 2).When placing back the state shown in Fig. 2 by moved by hand after automatic safety device action of the present utility model, for the protection act of next time is prepared.
In addition, the utility model stops the effect of warning of plate 2 in order to improve, preferably the obstruction plate 2 under folding arm 3 deployed condition can be arranged on be positioned at distance about 1.5 meters, hoistway door 4 dead ahead far, the overhead position of 1 meter high, and with warning signal such as warning sound, flash light etc. under the deployed condition of folding arm 3, and by networking forewarn system notice watch house personnel.
The utility model does not limit to and above-mentioned detailed description of the invention; according to foregoing; according to ordinary technical knowledge and the customary means of this area; do not departing under the utility model above-mentioned basic fundamental thought prerequisite; the utility model can also make the equivalent modifications of other various ways, replacement or change, all drops among protection domain of the present utility model.
