Abstract
The utility model discloses a movable roadblock and a trailer. A wheel carrier is hinged to a chassis around the axis stretching leftwards and rightwards. Follower wheels have walking positions located below the chassis and collecting positions where the follower wheels are turned upwards to the upper side of the chassis along with the wheel carrier on the rotation stroke of the wheel carrier. A locking device is arranged between the wheel carrier and the chassis. When the trailer travels to the appropriate place, the follower wheels are switched to the collecting positions from the walking positions, at this moment, the locking state between the wheel carrier and the chassis is eliminated through the locking device, so that the wheel carrier is separated from the chassis, the wheel carrier is capable of driving the follower wheels to be turned over to the upper side of the chassis, and a folding frame is located through contact between the chassis and the ground after the chassis falls down under the condition that the folding frame does not need to be detached from the chassis; when transfer needs to be conducted again, the folding frame is folded, the wheel carrier is turned down and locked through the locking device, the movable roadblock can be dragged away again, so that preparation time for erection and transfer of the roadblock is shortened, and the roadblock is more convenient to use.
