[0027] like Figure 1-6 As shown, an emergency braking device for a sightseeing train includes a brake sub-beam 1. Two pull rods 2 perpendicular to the brake sub-beam 1 are connected to both sides of the brake sub-beam 1. Connecting parts 21 are provided at both ends of the pull rods 2. A crank handle 3 is rotatably connected to the other end of the pull rod 2. The end of the crank handle 3 is located above the pull rod 2. A brake main rod 4 is connected above the crank handle 3. The brake main rod 4 includes a main brake column 41 rotatably connected to the upper part of the crank handle 3. A drive rod 42 is fixedly connected to the middle part of the main brake column 41.

[0028] In this embodiment, a non-powered bogie braking assembly is added to the non-powered bogie. When the air supply to the rear axle brake caliper is cut off, the piston rod of the rear axle brake caliper extends to the left, as shown in the reference. Figure 2 As shown, the rear axle brake caliper extends to the left, moving towards the brake sub-beam 1, thereby pushing the upper part of the main brake rod 41 to move to the left as well, while the lower part of the main brake lever moves to the right. The lower part of the main brake lever then drives the left brake shoe to clamp with the left wheel of the bogie first through the two first brake levers. When the upper part of the main brake lever continues to move to the left, after a certain distance, the right brake shoe will also lock with the right wheel. In this way, all four wheels are braked and locked, thereby achieving braking of the non-powered bogie.

[0029] Both ends of the brake sub-beam 1 are connected to the bearings via rear hangers, and both ends of the main brake column 41 are connected to the bearings via front hangers, thus braking the four wheels.
