When the first magnetic frame 5 and the second magnetic frame 6 are separated, the spherical head 17 can be freely flipped in the arc groove 19, so that the first magnetic frame 5 and the second magnetic frame 6 and the second magnetic frame 6 can swing with each other. During the process of the first magnetic frame 5 and the second magnetic frame 6 being adsorbed to the track, the angle between each other can be freely adjusted according to the curvature of the track, thereby preventing the electromagnet 7 from leaving the track and affecting the braking effect of the locomotive.

[0021] Reference Figure 1 , Figure 2 and Figure 4 The upper end surface of the brake box 1 is fixedly connected with a fixing frame 3, and the internal fixed connection between the limiting rod 9 and the extension rod 10 is provided with a rigid spring 15, which has good elasticity, thereby supporting the fixing block 8 and the limiting rod 9, and improving the stability of the fixing block 8 during movement.

[0022] Reference Figure 2-Figure 4, connecting grooves 12 are provided on the upper sides of both sides of the interior of the slide groove 11, and the limit rod 9 is located inside the connecting groove 12, and extension grooves 13 are provided on the lower sides of both sides of the interior of the slide groove 11, and the extension grooves 13 are connected with the connecting grooves 12, and the end faces of the two inclined plates 2 close to each other are provided with limit grooves 14, and the limit grooves 14 are connected with the slide groove 11, and the outer wall of the spherical head 17 is fixedly connected with a clamping block 18, and a clamping groove 20 is provided inside the arc groove 19, and the clamping block 18 is located inside the clamping groove 20, and the first magnetic suction frame 5 and the second magnetic suction frame 6 are fixed to each other, so as to limit and fix the first magnetic suction frame 5 and the second magnetic suction frame 6 well, so as to prevent the electromagnet 7 from shaking and colliding, causing damage to the electromagnet 7 and affecting the later braking effect, and the upper part of the brake box 1 is fixedly connected with an electromagnetic strip 4, and the upper end faces of the first magnetic suction frame 5 and the second magnetic suction frame 6 are fixedly connected with magnet sheets 21, and the electromagnetic strip 4 can drive the electromagnetic strip 4 to move up and down by adjusting the magnetic poles of the electromagnetic strip 4, which is convenient for later operation.

[0023] Working principle: install the fixing frame 3 to the position near the track at the bottom of the locomotive, start the electromagnetic strip 4, set the magnetic pole of the electromagnetic strip 4 to be opposite to the magnetic pole of the magnet sheet 21 above the first magnetic suction frame 5 and the second magnetic suction frame 6, and because the magnetic poles are attracted to each other, the electromagnetic strip 4 is attracted to the magnet sheet 21, and the first magnetic suction frame 5 and the second magnetic suction frame 6 enter the brake box 1. Under the extrusion of the inclined surface of the inclined plate 2, the first magnetic suction frame 5 and the second magnetic suction frame 6 are close to each other, and the ball head 17 moves in the arc groove 19 on the limiting cylinder 22 until the block 18 on the ball head 17 is inserted into the card groove 20 inside the arc groove 19, thereby well limiting and fixing the first magnetic suction frame 5 and the second magnetic suction frame 6;

[0024] When the vehicle needs to be braked, the magnetic poles of the electromagnetic strip 4 are set to be the same as the magnetic poles of the magnet sheet 21. Since the magnetic poles of the same polarity repel each other, the magnetic force of the electromagnetic strip 4 will push the first magnetic frame 5 and the second magnetic frame 6 to move in the direction of the track. The fixed block 8 on the first magnetic frame 5 moves in the slide groove 11 on the inclined plate 2, the limiting rod 9 moves in the connecting groove 12, and the fixed block 8 moves along the inclined surface of the inclined plate 2. The movement of the fixed block 8 drives the two first magnetic frames 5 away from each other, and at the same time pulls the multiple second magnetic frames 6 apart. The spherical head 17 moves in the arc groove 19 and disengages from the card slot 20 until the fixed block 8 enters the limiting groove 14, the limiting rod 9 enters the extension groove 13, and the rigid spring 15 When unfolded, the extension rod 10 pops out from the inside of the limit rod 9, and the limit rod 9 enters the extension slot 13. The fixed block 8 can move inside the limit slot 14. At the same time, the rigid spring 15 has good elasticity, thereby supporting the fixed block 8 and the limit rod 9, and improving the stability of the fixed block 8. When the electromagnet 7 under the first magnetic suction frame 5 and the second magnetic suction frame 6 is attached to the track, the electromagnet 7 is started, and the electromagnet 7 generates a strong magnetic force and is attracted to the track. The friction between the electromagnet 7 and the track is used to brake the locomotive. The simultaneous use of multiple electromagnets 7 can provide a stronger braking effect and can decelerate the locomotive faster, so that it can more easily cope with the track on the steep slope.

[0025] When a curve appears on the track, the first magnetic frame 5 and the second magnetic frame 6 and the second magnetic frame 6 and the second magnetic frame 6 are clamped together through the spherical head 17 and the arc groove 19, and the spherical head 17 can be freely flipped in the arc groove 19, so that the first magnetic frame 5 and the second magnetic frame 6 and the second magnetic frame 6 and the second magnetic frame 6 can swing relative to each other. During the adsorption process, the first magnetic frame 5 and the second magnetic frame 6 can freely adjust the angle between each other according to the curvature of the track, thereby preventing the electromagnet 7 from leaving the track and affecting the braking effect of the locomotive.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
