The embodiment of the application provides a railway crossing protector, can regard as railway crossing both sides to intercept the protection railing of passing vehicle or pedestrian, can be applicable to similar scene, including but not limited to setting up on the road surface of the both sides at railway crossing. For convenience of description, specific schemes of the embodiments of the present application will be described in detail below by taking an application scenario in which the railway crossing protection device provided by the present application is applied to both sides of a railway crossing to prevent collision between railway vehicles and road vehicles, pedestrians, and the like.

Referring to fig. 1, a railroad crossing refers to a crossing where a road 8 and a railway 9 cross on a plane, in order to ensure the smoothness of the railway, a railroad crossing protection device is arranged on the roads 8 on both sides of the railway 9 on the crossing, and when a train passes through the crossing, the crossing protection device is used for reminding and intercepting passing cars or pedestrians, wherein an arrow of a driving direction 10 drawn on the road 8 points to a normal traveling direction of traffic flow on a corresponding lane.

In order to ensure that the protective device can effectively intercept the vehicle, the base 1 is rotatably connected with the baffle 3, the baffle 3 and the central shaft axis of the base plate 1 in rotatable connection are arranged along the horizontal direction and are vertical to the advancing direction of the road vehicle, when the baffle 3 rotates around the central shaft axis of the baffle 3 in rotatable connection with the base plate 1, the baffle 3 can move between the passing position and the blocking position, because the rotatable connecting central shaft axis of the baffle 3 is horizontal and is vertical to the advancing direction of the road vehicle, the height of the baffle 3 only needs to correspond to the height of the vehicle, the track radius is small, the opening and closing speed is higher, meanwhile, the impact bearing position is closer to the supporting position, the moment is small, the bearing capacity is higher, and the vehicle stopping effect is better.

The passing position refers to a position where the baffle 3 is parallel to the road surface, so that road vehicles can pass through conveniently, namely the passing state of the device, and the blocking position refers to a position where the baffle 3 is vertical to the road surface and can block the road vehicles.

It should be noted that, there are many implementation manners of the rotatable connection, any connection that can realize the rotation of the baffle 3 around the fixed axis is possible, for example, the rotatable connection and the hinge connection, wherein the rotatable connection may be directly connected through a rotating shaft or may be connected through a bearing; the hinge joint can be connected by adopting a hinge shaft mode, and can also be connected by adopting a hinge mode and the like, and the preferable baffle 3 of the application is connected with the base 1 by adopting a hinge shaft 4.

Since there are various directions in which the barrier moves to the passing position, if the turning tendency of the barrier 3 from the blocking position to the passing position is set opposite to the traveling direction of the road vehicles, the blocked vehicles need to retreat so as to leave a space for the barrier 3 to be conveniently transported and restored to the passing position, thereby causing a certain disturbance to the traffic. Therefore, in an embodiment of the present application, in a manner that the turning tendency of the barrier 3 from the blocking position to the passing position is kept constant with the traveling direction of the road vehicle, the blocked vehicle does not interfere with the movement of the barrier 3 to return to the passing position, the barrier 3 can be directly turned to the passing position, the vehicle is allowed to pass, and the passing effect is better.

Since the baffle 3 is a component directly bearing impact, and the surface of the baffle directly contacts with the vehicle, scratching can be inevitably caused to the paint spraying and the like of the vehicle, and in order to reduce the loss of the vehicle and simultaneously improve the bearing capacity of the baffle 3, referring to fig. 2, in an embodiment of the present application, a cushion 33 can be fixed on the upper surface of the baffle 3. The cushion pad 33 is provided to protect the structure of the dash panel 3 and the surface of the vehicle.

The cushion 33 can be made of rubber and other materials, the form of the cushion 33 can be various, the cushion can be a whole cushion cut according to the contour of the upper surface of the baffle 3, and a plurality of small cushions 33 can be spliced and covered on the upper surface of the baffle 3.
