Here, the pole setting is fixed subaerial, the pole setting has two, sets up respectively in the both sides of remote country highway or dirt road, horizontal pole 2 is used for limit for height effect, just sets up two between the pole setting. The horizontal pole 2 sets up through both ends the drive bull stick 3 is installed respectively in the pole setting, drive bull stick 3 can rotate in the pole setting, specifically, set up on the stand 1 the shaft hole, set up on the drive bull stick 3 the pivot, the pivot is passed the shaft hole, the pivot with the shaft hole is rotated and is connected. When the cross rod 2 rotates to the highest position, the cross rod 2 is located at the highest station, and a special rescue vehicle can conveniently pass through the station. When the cross rod 2 rotates to the lowest position, the cross rod 2 is in a working position, and the vehicles with higher height are limited to pass through. More specifically, the driving rotating rod 3 can be a telescopic rod, so that the height of the cross rod 2 relative to the ground can be conveniently adjusted, and the application range of the whole device is widened.
In order to facilitate driving the cross bar 2 to rotate, the driving device is provided, the driving device is mounted on one of the columns 1, the driving device includes the driving wheel 41 and the driven wheel 42, wherein the driving wheel 41 and the driven wheel 42 are mounted on the column 1 and fixedly connected with a rotating shaft of the driving rotating rod 3 on the column 1, specifically, a central hole is formed in the driven wheel 42, and the central hole is in key connection with the rotating shaft. The driving wheel 41 is located below the driven wheel 42, more specifically, the driving wheel 41 and the driven wheel 42 may be gears, and the driving wheel 41 and the driven wheel 42 may be connected through gear transmission, more specifically, the driving wheel 41 and the driven wheel 42 may be sprockets, and the driving wheel 41 and the driven wheel 42 may be connected through chain transmission.
