Embodiment Construction
[0011] Such as figure 1 As shown, the pole shoe 1 of the magnetic rail brake is located directly above the top surface of the rail 5, the bottom of the pole shoe 1 is a boss structure 7, and the middle of the bottom surface of the boss structure 7 and the top surface of the rail 5 are two corresponding contact planes, Both sides of the top surface of the rail 5 are transitional curved surfaces, and the lateral width of the boss structure 7 is smaller than that of the rail 5 .
[0012] A side plate 4 and a T-shaped brake slider 3 are respectively arranged on the lateral sides of the boss structure 7, and the side plate 4 is fixed on the boss structure 7 by screws. On the same side of the boss structure 7, the side plate 4 A rectangular groove is formed between the boss structure 7, and the tops of several compression springs 2 and T-shaped brake sliders 3 are accommodated in the rectangular groove, and the top ends of the compression springs 2 are pressed against the boss struc...

The invention discloses a force-increasing device of a vertical sliding-type magnetic rail brake for braking a running railway vehicle. A boss structure with the horizontal width being less than that of a steel rail is arranged at the bottom of a pole shoe; a side plate and a T-shaped brake slider are respectively arranged on both horizontal sides of the boss structure; on the same side of the boss structure, a rectangular groove is enclosed between the side plate which is fixedly connected with the boss structure and the boss structure; a plurality of compression springs and the top of the T-shaped brake slider are contained in the rectangular groove; the bottom of the T-shaped brake slider extends outside the rectangular groove downwards and can slide up and down in the rectangular groove; the top end of the compression spring presses the boss structure and the bottom end of the compression spring and is supported on the top surface of the T-shaped brake slider; the bottom of the T-shaped brake slider is provided with an arc-shaped guide rail groove; the arc-shaped guide rail groove is matched with transitional curved surfaces on both sides of the top surface of the steel rail; when the bottom surface of the boss structure is contacted with the middle of the top surface of the steel rail, the arc-shaped guide rail groove is tightly fitted with the transitional curved surfaces on both sides of the top surface of the steel rail, so that the contact area between the pole shoe and the steel rail is increased, and the brake force is effectively increased.
Description
technical field [0001] The invention belongs to the field of rail vehicle braking, in particular to a booster device for increasing the braking force by increasing the friction between the pole piece of the magnetic rail brake and the rail. Background technique [0002] The magnetic track brake is mainly composed of brake beams, suspension and lifting devices, magnets, pole shoes, etc., such as the brake described in the patent application number 201210408048.7 and the name "An Electromagnetic Magnetic Track Brake". The working principle of the magnetic rail brake is: under the action of the magnetic force, the pole shoe of the brake and the rail generate frictional resistance due to relative movement, so as to realize deceleration and braking. [0003] The cross-section of the rail is I-shaped, and the middle of the top surface is flat, but the left and right sides of the top surface are transitional curved surfaces connected to the side surfaces. The bottom of the pole sho...
