Emergency braking device for RGV

According to the RGV emergency braking device, a braking device is arranged on a wheel set, when a handle is pressed downwards to enable an eccentric wheel to rotate, the end, far away from the rotating center, of the eccentric wheel can move downwards, a shell and a connecting rod can be driven to move downwards, and therefore a braking rod can be pulled to rotate around a short pin shaft; the brake pad on the brake rod can be pressed on the wheels to generate braking force, so that the device can be quickly used for braking when the rail trolley is suddenly out of order or has other faults and cannot be stopped in the running process, quick, timely, reliable and stable braking of the RGV trolley is realized, safety accidents are avoided, and the safety of the rail trolley is improved. Therefore, the rail trolley can be braked under the emergency condition or under the condition that other braking devices fail or are delayed. 本实用新型公开了一种RGV小车紧急制动装置，通过在车轮组上设置有制动装置，其中，在下压手柄使偏心轮转动时，偏心轮离旋转中心较远的一端会下移，会带动外壳与连杆下移，从而
