Description
Technical field
The utility model relates to a kind of obstacle detector for Lift car type elevator doorway.
Background technology
In Lift car type elevator system, obstacle is there will be in the normal switch door process of elevator door-motor, this obstacle is likely people or the thing that just in time will enter car in door closing procedure, also be likely other objects of other harm elevator safety operations, go to consider from the angle of personal safety, all can lift-mounting doorway obstacle detector on present elevator door-motor, conventional detecting device has contact-type detection (safety edge) or contactless detection device (infrared ray curtain).The former must arrange several travel switch, and not only structure is comparatively complicated, and need by mechanical action trigger switch, touch panel action is too large, because its service lifes such as wearing and tearing are affected, also easily there is blind area in the edge of each travel switch range of control, the above safety all affecting fender guard; The structure of the latter is more complicated, and cost is high, and check frequency is also larger.
Summary of the invention
The purpose of this utility model is for prior art above shortcomings, provides a kind of elevator doorway obstacle detector, and not only structure is comparatively simple for it, and mechanical action does not occur, longer service life, and add without check frequency, safety is good.
For achieving the above object, elevator doorway of the present utility model obstacle detector, comprise left and right door leaf shell, it is characterized in that all being installed with capacitive induction soft-touch control in left and right door leaf shell, the adjacent outer face of left and right door leaf shell is all installed with resistive touch switch, each resistive touch switch comprise be fixed on longitudinal arrangement on respective door leaf housing outward end face several strain resistors, be located at the sensor block before all strain resistors, the resistive touch switch on two door leaf shells shifts to install on the direction perpendicular to the movement of door leaf shell.
During use, left and right door leaf shell in the process of closing the door, as in the two any one close to the obstacle of static electrification, the first action output signal of capacitive induction soft-touch control, the dynamo-electric machine of this signal control door is avoided closing the door; As in the two, any one runs into the obstacle of not static electrification, capacitive induction soft-touch control is inoperative, but the strain resistor at the sensor block of resistive touch switch extruding rear, strain resistor output signal, can avoid closing the door by the dynamo-electric machine of control gate equally, so all obstacles all can detect; The two resistive touch switches shifted to install can cover the whole end face of door leaf shell; The utility model not only structure is comparatively simple, and detecting element mechanical action does not occur, longer service life, capacitive induction soft-touch control is the same with shell is also strip, add that sensor block can be contour with door leaf shell, without check frequency, guarantee safety at closing time;
As further improvement of the utility model, described two door leaf shell end faces are equipped with the step of mutual dislocation, and the resistive touch switch on two door leaf shells is all corresponding with the step of the other side; The door leaf shell of resistive touch switch and the other side can be avoided to collide, and two resistive touch switches partly overlap in the direction of movement simultaneously, can further improve safety;
As further improvement of the utility model, described capacitive induction soft-touch control is located on the adjacent inner end surface of left and right door leaf shell; The distance of two capacitive induction soft-touch controls can be shortened to greatest extent, improve the safety to electrostatic detection of obstacles;
In sum, the utility model not only structure is comparatively simple, and mechanical action does not occur, longer service life, and add without check frequency, safety is good.

Fig. 2 is the longitudinal sectional view of single door leaf shell in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, this elevator doorway obstacle detector, comprise left-hand door fan shell 1, right door leaf shell 2, the end face of described two door leaf shells 1,2 is equipped with the step of mutual dislocation, two door leaf shells 1,2 adjacent inner end surfaces are all installed with capacitive induction soft-touch control 3, the outer face of left and right door leaf shell 1,2 is all installed with resistive touch switch 4, two resistive touch switches 4 are all corresponding with the step of the other side, that is shift to install on the direction perpendicular to the movement of door leaf shell; Each resistive touch switch 4 comprise be fixed on longitudinal arrangement on respective door leaf housing outward end face several strain resistors 5, be located at the sensor block 6 before all strain resistors 5, sensor block 6 can be connected with strain resistor 5 or door leaf shell.
During use, left and right door leaf shell 1,2 is in the process of closing the door, as any one obstacle close to static electrification (as human body) in the two, electric first action output signal responded to obtain by capacitive induction soft-touch control 3, for non-contact detection, capacitive induction soft-touch control 3 is placed in shell to be protected, and the dynamo-electric machine of this signal control door is avoided closing the door; As in the two, any one runs into the obstacle of not static electrification, capacitive induction soft-touch control 3 is inoperative, but the sensor block 6 of resistive touch switch 4 extrudes the strain resistor 5 at rear, strain resistor output signal, can avoid closing the door by the dynamo-electric machine of control gate equally, so all obstacles all can detect; And the two resistive touch switches 4 that shift to install corresponding with the step of the other side, not only can cover the whole end face of door leaf shell, and avoid resistive touch switch 4 to collide with the door leaf shell of the other side, the detection range of two resistive touch switches 4 partly overlaps in the direction of movement simultaneously, can dead zone-eliminating completely, add that two capacitive induction soft-touch controls 3 are located on two door leaf shells 1,2 adjacent inner end surfaces, the distance of the two can be shortened to greatest extent, eliminate the blind area to electrostatic detection of obstacles; The utility model not only structure is comparatively simple, and detecting element mechanical action does not occur, longer service life, capacitive induction soft-touch control 3 is the same with shell is also strip, add sensor block 6 can with two door leaf shells 1,2 contour, without check frequency, guarantee safety at closing time.
