The specific embodiment
Below in conjunction with Fig. 1 to Fig. 4, gate shear door machine structure of the present utility model is made and being illustrated.
This gate shear door machine structure comprises frame 3 and is hinged on the door-plate 1 in frame, motor 11 is installed in described frame, between described motor and door-plate, be provided with belt wheel transmission mechanism driving, described belt wheel transmission mechanism is provided with electric brake 10, the position that described upper electric brake is realized door-plate when powering on keeps, and realizes rotating freely of door-plate during power down.Described belt wheel transmission mechanism comprises large Toothed belt pulley 6, little Toothed belt pulley 9, between described large Toothed belt pulley and little Toothed belt pulley, by Timing Belt 8, synchronize and rotate, the output shaft of described motor connects little Toothed belt pulley, and described large Toothed belt pulley connects door-plate.Described upper electric brake 10 is fixedly connected with the rotating shaft of frame 3 and little Toothed belt pulley 9 simultaneously.On described door-plate 1, be provided with door-plate fixation of sensor 12, be provided with the frame stopper slot 13 of arc in described frame, described frame stopper slot two ends are the switch gate position of corresponding door-plate respectively.Between described door-plate and frame, be provided with an extension spring 2.In described frame, be provided with frame extension spring fixed bar 4, be provided with door-plate extension spring fixed bar 5 on described door-plate, the two ends of described extension spring 2 are arranged on respectively on frame extension spring fixed bar and door-plate extension spring fixed bar.
The output shaft of motor 11 connects with little Toothed belt pulley 9 fixing by key.Large Toothed belt pulley 6 is connected on door-plate by Timing Belt fixed screw 7.Upper electric brake 10 is not when charged, and door-plate 1 can freely rotate around the shaft, can realize the automatic brake functions of door-plate while powering on, and realizes door-plate optional position and keeps.Described upper electric brake 10 is fixedly connected with the rotating shaft of frame 3 and little Toothed belt pulley 9 simultaneously, is function, the preferred magnetic powder brake of upper electric brake or the dental inlay type brake of holding turning cylinder brake tightly.
Illustrate operating principle of the present utility model below:
When ticket checking machine is in treating current state, now the door-plate 1 of scissors door is in closed condition.Meanwhile go up electric brake 10 energisings, realize the maintenance of the position of closing the door.Now in the door-plate end power of opening the door, depend on moment of torsion and the speed reducing ratio of electric brake 10.If now for security consideration system cut-off, under the effect of extension spring 2, door-plate 1 rotates counterclockwise, extension spring 2 pulls door-plate 2 to get back to door opening state.
When having current order to assign, motor 11 starts to rotate counterclockwise, drive little Toothed belt pulley 9 to rotate counterclockwise, little Toothed belt pulley 9 drives large Toothed belt pulley 6 to rotate counterclockwise with door-plate 1 by Timing Belt 8, the execution action of opening the door, when the door-plate fixation of sensor 12 of door-plate 1, encounter the opening position of frame stopper slot 13, show the end of opening the door.Treat that passenger is current complete, motor 11 starts to clockwise rotate, drive little Toothed belt pulley 9 to clockwise rotate, little Toothed belt pulley 9 drives large Toothed belt pulley 6 to clockwise rotate with door-plate 1 by Timing Belt 8, the execution action of closing the door, the position of closing the door when the door-plate fixation of sensor 10 of door-plate 1 is encountered frame stopper slot 13, shows the end of closing the door.
