Detailed description of the invention
nullA kind of embodiment of the elevator car structure of anti-accidental movement，At Fig. 1、In Fig. 2 and Fig. 3，Its guide rail 1 is two，It is respectively used to be assemblied in hoistway，Slide on guide rail 1 and be provided with car，The upper and lower of car is provided with crossbeam 3，The two ends of two crossbeams 3 are respectively arranged with left vertical beam 4 and right vertical beam 5，Two crossbeams 3 and left vertical beam 4 and right vertical beam 5 form frame-shaped，Car is in this frame，Crossbeam 3 directly contacts with steel wire rope，Above structure is conventional structure of the prior art，The crossbeam 3 be in top is rotatably equipped with flange rotating disk 6，Crossbeam 3 is fixed and is equipped with motor，The output shaft position of motor has shutdown band brake apparatus，Shutting down band brake apparatus will be locked by motor in motor one shutdown，Such motor belongs to commercial part，Motor is connected with flange rotating disk 6 by decelerator 7，Flange rotating disk 6 is driven to rotate，Outer rim position symmetry at flange rotating disk 6 rotates and is provided with connecting rod 8，One end of connecting rod 8 rotates assembling with flange rotating disk 6，Connecting rod 8 rotates assembling with flange rotating disk 6 by oscillating bearing，The other end of connecting rod 8 is all hinged with latch 9 by oscillating bearing，Latch 9 is slidedly assemblied on crossbeam 3，Flange rotating disk 6、Connecting rod 8 and latch 9 form crank block structure，Here latch 9 is slidedly assemblied on crossbeam by latch support 10，Latch support 10 is fixed on crossbeam，Latch 9 coordinates with the slideway in latch support 10，Here connecting rod 8 is Split type structure，By the union joint at two ends and middle screw mandrel，The two ends of screw mandrel are provided with external screw thread，The termination of two union joints has tapped blind hole，The two ends of screw mandrel screw in the screwed hole blind hole of two union joints，Connecting rod 8 rotates assembling by union joint with flange rotating disk 6 and latch，The connecting rod of this structure can adjust length easily，The extreme position of latch 9 can be adjusted with this.The free end of latch 9 is the reducing conical surface towards termination.Fixing on guide rail 1 and be equipped with guide rail connecting bottom board 11, guide rail connecting bottom board 11 is in the level position of car, and each level position has one piece.Guide rail connecting bottom board 11 can be fixed on guide rail 1 by pressure guide plate, reinforcing plate 12 it is provided with on guide rail connecting bottom board 11, pin hole is begun with in reinforcing plate 12, the hole wall of pin hole here is the conical surface that the conical surface section with latch 9 matches, latch 9 stretches into pin hole at an extreme position, deviates from pin hole at another extreme position.The tapering of latch 9 is more than the angle of friction between latch 9 and pin hole, and such latch 9 can be easily owing to extracting in pin hole, will not be locked.nullLift car leveling when，Turnover personage once occurs，The overall weight of car will change，In this case，Steel wire rope tension can change，Steel wire rope there will be the phenomenon elongated or shortened，Due to coordinating between latch with pin hole，Car will not move relative to guide rail，The power that the most this change produces just will be undertaken by latch，Balanced by the pressure between latch and latch hole wall，Car load change the most greatly time or time phenomenon that traction machine skids occurs，Act on the power on latch the biggest，The biggest in the frictional force resulted between latch and latch hole wall，The power that motor gives latch by slider-crank mechanism cannot exceed this frictional force，Result in latch cannot extract，The problem that elevator device cannot run，When the front end of latch 9 is done tapered，Its taper angle is a，The power that car is added on latch is f，So，Coefficient of friction between latch and pin hole hole wall is u，So，Frictional force suffered by latch is just: ufcosa，And the power driving latch to remove is: fsina，If fsina > ufcosa，Then latch can be deviate from automatically，If namely tana > u，And u is equal to friction tangent of an angle，Namely a > angle of friction，As long as i.e. the tapering of latch is more than angle of friction，Latch just can be deviate from by pin hole，Will not be locked，Owing to latch is when inserting pin hole，Latch is in the dead-centre position of slider-crank mechanism，The power being added on slide block is the biggest，Slider-crank mechanism also will not move，So have only to motor have prevent from shaking the crank displacement that brings hold strength tightly，Ensure that latch is not deviate from from pin hole，It is constantly in locked state.When latch needs abjection from pin hole, motor only need to drive flange rotational motion, cross dead-centre position, and latch will be deviate from automatically, does not haves locked problem.
Crossbeam 3 is equipped with detection switch 13, latch 9 offers groove 2, when latch 9 is in the extreme position of abjection pin hole, the contact of detection switch 13 stretches in groove 2, and this contact for detection switch being is in the state that freely overhangs, not by any pressure, latch 9 outer move stretch in pin hole time detection switch 13 contact will by groove 2 in deviate from, also will be depressed by latch 9, the sidewall of groove 2 is for convenience of the inclined-plane of contact abjection, and the bottom surface of groove 2 is plane.
In use, the line switching of motor is controlled break-make by elevator controlling mainboard, and detection switch 13 is connected with the transmission of elevator controlling mainboard, can transmit signal to elevator controlling mainboard.When lift car leveling, elevator controlling mainboard controls motor work, driven by motor flange rotating disk rotates, latch is driven to move to stretch into the extreme position of pin hole, at this moment the contact abjection groove of switch is detected, its signal passing to elevator controlling mainboard changes, after elevator controlling mainboard receives the signal changed, control motor stopping, latch is parked in the extreme position stretching into pin hole, car will not move, after elevator turnover people or thing, the end, weighs the most overweight in switching detection car, if meeting elevator loading, elevator controlling mainboard sends signal control motor and again rotates, latch leaves pin hole and regains, and make the groove on latch move to detection switch, detection switch is no longer triggered, the signal of detection switch converts again, elevator controlling mainboard receives the signal after conversion, permission elevator continues to run with.nullAbove-mentioned control mode is common knowledge，Elevator controlling mainboard is when flat bed，When making the instruction that traction machine is shut down，Control electric machine rotation simultaneously and belong to common knowledge，Principle with the electric machine rotation with shutdown that control driving traction machine is the same in fact，And give，Control motor stalling when the signal of the detection switch that elevator controlling mainboard receives changes and fall within routine techniques，In like manner，The most above-mentioned condition of those skilled in the art can not spend creative work just to design satisfactory control circuit，Receive the signal meeting elevator loading at elevator controlling mainboard while，Trig control signal，Motor is rotated at this，Fall within routine techniques，Equally，Control motor stalling when the signal of the detection switch that elevator controlling mainboard receives changes again and equally belong to routine techniques，The control technology of above-mentioned routine only need to be added in the circuit of elevator controlling mainboard by those skilled in the art，Therefore，Here，Circuit composition and connected mode are the most no longer described in detail in detail，And，Nonetheless，Technology is also open sufficient.
The present embodiment is according to illustrating of making this utility model, and is not that corresponding structure can be not provided with in other embodiments to restriction of the present utility model, the function in need not appended claims.
Any technical scheme carried out technical characteristic of the present utility model obtained by equivalent falls within the scope of this utility model protection.
