Abstract

The present invention relates to the technical field of magnetic rail brakes, in particular to a device for testing the electromagnetic force of magnetic rail brakes. The trough is vertically set between the segmented rails, the limit plate is fixed on the inner wall of the trough, and the force measuring rail block and the elastic force measuring device are located inside the trough, and the bottom of the force measuring rail block is connected with the elastic measuring rod through the middle connecting rod. The force device is connected with the tensile machine. Compared with the traditional force measuring device, the suction test device has a simple structure and convenient force measurement. It can efficiently and accurately measure the electromagnetic attraction value of the magnetic track brake to ensure the reliability and safety of the train brake. .

Description

technical field [0001] The invention relates to the technical field of magnetic track brakes, in particular to an electromagnetic attraction testing device for magnetic track brakes. Background technique [0002] With the rapid development of rail vehicles such as high-speed trains, subways, and light rails, magnetic rail brakes, as an indispensable braking component in the braking system of rail vehicles, have also been rapidly developed and applied. Electromagnetic attraction is the most important technical index of the magnetic track brake, and its performance directly affects the braking force of the magnetic track brake on the train. Therefore, the efficient and accurate measurement of the electromagnetic attraction value of the magnetic rail brake is of great significance for the development of the magnetic rail brake and the safety of train braking. [0003] At present, there are many methods for measuring the electromagnetic attraction force of magnetic track brakes...
