Adopt electronic barring under most conditions, still be connected with driving motor 6 on the speed reducer 3, when needing to carry out the barring, the staff starts driving motor 6, can drive speed reducer 3, and then drives the operation of barring device main part 2, realizes the barring effect. When the electric barring gear breaks down and needs to move the barring gear, a worker unloads the driving motor 6 and then unloads the speed reducer 3, and the clamp arm 5 is also simultaneously taken down and placed in the clamp arm placing groove 51.

In this embodiment, through fixed card arm standing groove 51 that sets up on bottom plate 1, can place card arm 5 in card arm standing groove 51 when carrying out the pneumatic driving disk vehicle, avoided card arm 5 to place or by other staff's mistake take to cause and lose everywhere.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
