Detailed description of the invention
With reference to accompanying drawing, the utility model comprises two way cylinder 1, reservoir fulcrum block 2, elasticity locking device 3, reservoir push rod 4, the first lever 5, the first balance pivot seat 13, shutter door mechanism, shutter door mechanism is made up of pipe link 6, backstop 7, Y type lever 11, the first push rod 9, Y type balance pivot seat 10, the second push rod 12, the middle part fulcrum of Y type lever and Y type balance pivot seat chain connection, fulcrum and pipe link in three end fulcrums of Y type lever are hinged, two other fulcrum is hinged the first push rod and the second push rod respectively, and backstop 7 is connected on Y type lever; Elasticity locking device is made up of stage clip 14 and latch hook 15; Two way cylinder chain connection is on reservoir fulcrum block, reservoir push rod is connected on two way cylinder, elasticity locking device is fixed on two way cylinder, and latch hook coordinates with reservoir push rod, reservoir push rod is carried out to locking, and one end of the first lever and reservoir push rod are hinged, middle part fulcrum and the first balance pivot seat is hinged, one end of the pipe link of the other end and shutter door mechanism is hinged.
The utility model is arranged on underframe, and is positioned on car body longitudinal centerline.Reservoir fulcrum block 2 is welded on bottom frame floor, and two way cylinder can rotate counterclockwise around reservoir fulcrum.Elasticity locking device 3 is secured by bolts on two way cylinder, and the stage clip 14 in elasticity locking device 3 has certain precompressed compression to latch hook 15, and latch hook arc surface contacts with the boss of reservoir push rod 4.The first balance pivot seat 13 is welded in plane on underframe central sill, and Y type balance pivot seat 10 is welded in underframe central sill lower plane.
The utility model can, according to the needs of hopper wagon bottom door quantity, longitudinally arrange Duo Zu shutter door mechanism along car body, and Ge Zu shutter door mechanism, each other by pipe link chain connection, realizes interlock; Embodiment of the present utility model provides Liao Liangzu shutter door mechanism, and the pipe link 8 of the second shutter door mechanism is hinged with pipe link 6.On each fan bottom door of car body, be all welded with Connection Block, the end of the first push rod 9 and the second push rod 12 respectively with the bottom door Connection Block chain connection of both sides.
