Problems solved by technology

[0004] The above-mentioned railroad crossing protection device adopts the form of railings, which are set horizontally and open and close along the vertical surface of the road vehicle's traveling direction, resulting in slow opening and closing speed. At the same time, due to the lack of support at the far end, the structure is fragile. If the distance from the support point is too far, the force arm of the impact force is long, and the force on the support point is too large, which is easy to be damaged, and it is difficult to effectively intercept the vehicle, causing the vehicle to rush into the railway, causing more serious traffic accidents

Abstract

The embodiment of the invention discloses a railway crossing protection device, relates to the technical field of railway crossing protection, and solves the problems that an existing railway crossing protection device is fragile in structure and poor in stopping effect. The railway crossing protection device comprises a base arranged on the ground, the base is rotatably connected with a baffle, the central axis, rotatably connected with the base, of the baffle is arranged in the horizontal direction and is perpendicular to the advancing direction of road vehicles, and when the baffle rotates around the position, rotatably connected with the base, of the baffle, the baffle can move between the passing position and the blocking position, a positioning mechanism is arranged between the base and the baffle, and when the baffle rotates to the blocking position, the positioning mechanism fixes the relative position of the base and the baffle. The railway crossing protection device is used for being arranged at a railway crossing to prevent collision between railway vehicles and road vehicles, pedestrians and the like.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of railway crossing protection, and in particular relate to a railway crossing protection device. Background technique [0002] Railroad crossing protection refers to the safety measures taken to prevent the collision of vehicles and pedestrians in the direction of crossing on level crossing railway and road crossings, and is generally implemented by railroad crossing protection devices. The number of motor vehicles in my country has increased year by year. After adding protective devices at crossings, traffic accidents have dropped significantly. Crossing protection is of great significance to improving road passing capacity and ensuring driving safety. Safe and reliable crossings are set at the intersection of railways and roads. Protective devices are especially important. [0003] Most of the existing safety protection devices are fences or gates. The opening and...
