Specific embodiment

With reference to embodiments and attached drawing the invention will be further described.

Referring to Figures 1 and 2, the present invention includes motor 1 and diverter 2, which is fixedly connected with steering Device input shaft 21, the diverter output shaft 22 connect door leaf axis 7 by dissection type plum coupling 6.Dissection type plum coupling 6 Characteristic determine that this is determined shaft coupling and allows certain axial error, to reduce the requirement of installation and processing.

Referring to Fig.1, Fig. 3 and Fig. 4 is also equipped with brake 3 and torque force limiting device on diverter output shaft 22 of the present invention 5。

The brake 3 includes electromagnetic disc 31, floating disc 32 and top plate 33.The electromagnetic disc 31 is by bearing 10 and turns to Device output shaft 22 is rotatablely connected, and in addition which is also fixedly connected with the shell of diverter 2, the top plate 33 passes through bearing 9 are rotatablely connected with diverter output shaft 22, which is equipped with gear, and the floating disc 32 passes through its inner ring gear and top 33 outer ring gear of disk is meshed.

31 upper end of electromagnetic disc of the brake 3 and the lower end of floating disc 32 are equipped with floating disc 32 respectively and are inhaled by electromagnetic disc 31 Conjunction being capable of intermeshing tooth.

The torque force limiting device 5 includes axle sleeve 51, ring flange 53 and lower friction plate 52 and upper friction plate 54.Torsion limitation The axle sleeve 51 of device 5 is fixedly connected with diverter output shaft 22 by key, equipment run well when, entire torque force limiting device 5 with It is rotated freely with diverter output shaft 22.

Ring flange 53 is set in outside the axle sleeve 51 of torque force limiting device 5, and solid by terminal pad 4 and the top plate 33 of brake 3 Fixed connection, 4 lower end of terminal pad are fixedly connected on the same bearing 9 connecting with brake top plate 33, and defeated with diverter Shaft 22 is in rotation connection shape.

The present invention is equipped with the lower friction plate 52 being set in outside axle sleeve 51 below ring flange 53, and in lower flange 53 It is equipped with the upper friction plate 54 being set in outside axle sleeve 51, and the nut 57 by being set in outside axle sleeve 51, disc spring 56 and pressing plate above 55 are fixed.

Referring to Fig.1 and Fig. 5, diverter countershaft 23 of the present invention are also connected with an accumulator 8.

The accumulator 8 includes shell 81, wind spring 82 and cover board 83.Its shell 81 is fixedly connected with 2 shell of diverter, volume Spring 82 is set among accumulator shell 81, and the inner end of the wind spring 82 is fixedly connected with diverter countershaft 23, the outer end of the wind spring 82 It is fixedly connected with accumulator shell 81.

It is used on automatic ticket checker below by way of the present invention and sketches its working principle:

It starts running after the energization of motor 1, the rotary force of motor 1 is defeated by 2 vertical direction output shaft 22 of diverter Out, dissection type plum coupling 6 is driven, is transmitted on door leaf axis 7, so that door leaf be driven to do the movement of switch gate.

Under the closed state of channel, when passenger or pedestrian break in automatic ticket checker, incuded by sensor, with 31 energization action of rear brake electromagnetic disc, floating disc 32 are attracted down by strong magnetic, the tooth of 32 lower end of floating disc and and electromagnetic disc The tooth engagement of 31 upper ends, brake 3 lock entire mechanism, pass through pedestrian can not directly under illegal state.

After pedestrian exits channel (sensor sensing in channel less than channel in someone when), brake electromagnetism It disengages and resets automatically after 31 power loss of disk, door leaf mechanism operates normally again.

If passenger or pedestrian's row when someone thrusts oneself in situations such as pushing perhaps door leaf appearance folder people or luggage Li Weineng exits channel in time, and by after strong magnet attraction, entire mechanism is locked brake floating disc 32.But for safety and The needs for protecting equipment etc., allow to open door leaf by force at this time.According to the relationship of active force and reaction force, when what is pushed When power is greater than power (power can be obtained according to different demands adjusting nut 57) of torque force limiting device 5, torque force limiting device 5 goes out Existing slipping phenomenon, door leaf can be open.Pedestrian or luggage can guarantee to exit channel in time, and entire mechanism is also unlikely to Because stress causes equipment to break down very much greatly.The door leaf people that is open exits after channel, and inductor incudes less than channel cataract or glaucoma Hinder the presence of object and door leaf mechanism automatically resets, channel can be closed in time.

In addition, the wind spring 82 in accumulator 8 rotated during installation after energy storage.Energy storage after device powers down in wind spring 82 It is discharged by diverter 2, drives door leaf axis 7 to rotate at this time, in emergency circumstances or when accident occurs entirely led to guarantee In the state that road is the enabling kept forever, play the role of escape route guidance and evacuation crowd.
