Title:
Test equipment for electromagnetism power of absorption of a magnetic track brake
Document Type and Number:
Japanese Patent JP6228321
Kind Code:
B2
Abstract:
The present application relates to the technical field of magnetic track brake, and in particular to a testing device for electromagnetic attraction force of a magnetic track brake, comprising a steel rail, a force measuring rail block, a guide groove, an elastic force measuring device and a pull machine, wherein the steel rail consists of segmented steel rails, the groove body of the guide groove is vertically provided between the segmented steel rails, the limiting plate is fixed on an inner wall of the groove body, the force measuring rail block and the elastic force measuring device are both located inside the groove body, and a bottom of the force measuring rail block is connected to the elastic force measuring device and the pull machine through an intermediate connection rod. As compared with the conventional force testing device, the attraction force testing device is simple in structure and convenient for the force test, and it can high-efficiently and accurately measure the electromagnetic attraction force of the magnetic track brake, and ensure reliability and security of the train travel braking.
