The invention relates to a barb type brake wheel device. Brake pedals are arranged on the two sides of a wheel framework, a wheel is arranged in the wheel framework, arc-shaped brake shoes are arranged between the brake pedals and the wheel, the arc-shaped brake shoes are fixedly connected to the brake pedals, barb devices are respectively mounted on the two sides of the arc-shaped brake shoes, a plurality of arc-shaped plates are respectively arranged on the two sides of the wheel, and the plurality of arc-shaped plates are uniformly distributed into a circle. The arc-shaped brake shoes mounted below the brake pedals can be well engaged with the outer contour of the wheel, so that a brake effect is realized. The barb devices are respectively mounted on the two sides of the arc-shaped brake shoes, the six arc-shaped plates are respectively arranged on the two sides of the wheel and are uniformly distributed into one circle, and the contours of the barb devices and the arc-shaped plates are engaged with each other and can be hooked with each other, so that the brake safety is improved. Telescopic elastic rod devices are mounted on the two sides of the brake pedals, so that a brake effect can be easily realized by using the brake pedals. The barb type brake wheel device can solve the defects of the existing device, is simple in operation method, has certain portability, and meanwhile, reduces certain potential safety hazards for operators and environments.
