Abstract
The utility model relates to a cam-shaped lifting type wheel block. Friction brake pads are installed at two sides of a steel rail through bolts. Supporting chunks are clamped by clamping plates and installed at the two sides of the steel rail through bolts. The top end of each clamping plate abuts against one friction brake pad. The clamping plates at the two sides are respectively provided with a rotary shaft sliding groove. A rotary shaft penetrates through the rotary shaft sliding grooves in the clamping plates arranged at the two sides and is locked with a lifting cam through nuts and the rotary shaft moves forwards and backwards in the rotary shaft sliding grooves. The lifting cam rotates around the rotary shaft. Two sides of each clamping plate are respectively provided with an ejector rod through a support. A compression spring is stringed in the middle of each ejector rod. The head portion of each ejector rod abuts against the head portion of the rotary shaft. An extension spring is connected between the lifting cam and the supporting chunk. When a wheel makes contact with the lifting cam, the lifting cam is lifted automatically and stops the wheel, the lifting cam abuts against the supporting chunks, the supporting chunks drive the clamping plates at the two sides to push the friction brake pads to achieve a braking function so that the purposes that an uncontrolled vehicle is braked and the vehicle is prevented from going off the rail are achieved. The phenomenon that parts located in the front end portion of each wheel of the vehicle are damaged due to the fact that supporting chunks of an existing wheel block is high above the rail surface is avoided.
