Protective devices FOR unguarded railway crossings

摘要

The technical solution relates to the field of rail transport, namely to the devices intended to prevent unauthorized entry to the vehicle when approaching a railway crossing thereto trains. The objectives of the proposed utility model is to improve the reliability of the barrier device and reduce the cost of its operation. The problem is solved in that the protective devices for unprotected level crossing, placed across the road, which includes a base support frame structure, on which is hinged a protecting member and a lifting mechanism (lowering) of the barrier member, a protecting member is a metal cap, made in a prism, and through the intermediate link is pivotally coupled to the lifting mechanism (lowering) due to the buoyancy force, represented hollow p oplavkom located in a non-freezing liquid container and having flooding and surfacing system. This system is installed on the float is represented by the motor pump, flooding valves and the pushers in the upper part of the float, the bypass tubes for filling with liquid and the float stops of the float-lifting height limiters. Container with antifreeze liquid is placed in a concrete pit. Thus, the implementation of a utility model solves all the tasks authors.
