Description

Derailment brake device for railway freight car Technical Field The utility model belongs to the technical field of train braking, and particularly relates to a railway freight car derailment braking device. Background Derailment of wheels of rail wagons is a serious accident risk during high speed operation or under complex road conditions. Derailment of the wheels may be caused by a variety of factors including deformation of the track, uneven wear of the wheels, structural defects of the axle, and foreign or water accumulation of the track. During train operation, the axles and wheels are subjected to significant dynamic loads, and the wheels may deviate from the track, especially when passing through curves or rough roads. If the axle is abnormally jumped or swung, the angle and the pressure of the wheels contacting the track can be changed, so that the relative movement between the wheel tracks is unstable, and the wheels can be derailed, therefore, the running state of the axle, especially the jumping condition of the axle, is monitored in real time, and is important for preventing and timely coping with the derailing risk; The laser correlation sensor usually relies on fixed mounting position and alignment direction to measure, and at present, the application of the laser correlation sensor in railway freight car axle detection mainly adopts a fixed mounting mode, and the position and the height of the fixed mounting sensor are usually preset according to the axle and the wheel diameter of a specific model, which means that the detection range of the sensor is fixed and cannot automatically adapt to the change of different axle diameters, and the diameter of the axle can be changed due to the different train models, carrying capacity and manufacturing tolerances, so that the fixed mounting laser correlation sensor can only effectively detect the axle in the specific range, and the detection precision of the axle beyond the specific range can be greatly reduced, and in addition, the fixed mounting sensor is difficult to quickly adjust to adapt to the detection requirements of trains with different specifications. Disclosure of utility model The present utility model aims to provide a railway wagon derailment brake device which solves at least one of the problems and drawbacks set forth in the background art above. The utility model provides a railway freight car derailment arresting gear, including the mount pad body, the inside sliding connection of mount pad body has the regulation pole, regulation pole below fixedly connected with mount, the mount both sides are provided with the connecting plate, connecting plate upper portion all is provided with electronic slide rail, the equal sliding connection in electronic slide rail both sides has electronic slider, all be provided with a section of thick bamboo on the electronic slider, be provided with the mounting groove in the mounting groove, equal joint has the cassette in the mounting groove, threaded connection has laser correlation sensor in the cassette.
