As further improvement of the utility model, the bottom surface of described braking iron wedge have a sawtooth, further strengthen the friction force of glancing impact.
As further improvement of the utility model, the rear portion of braking iron wedge is slightly acclivitous inclined-plane, the back bottom surface of raising is more prone to the front portion of braking iron wedge when the large scale hoisting machinery wheel bottom that insertion is braked, and behind the wheel compacting braking iron wedge that is braked, the rear portion pressurized of braking iron wedge is downward-sloping, the front portion of braking iron wedge has perk slightly, can more effectively prop up moving of wheel.
As further improvement of the utility model, in described transmission device, be provided with setting device between the L shaped crank of connection braking iron wedge and the braking iron wedge.Described setting device is: be provided with the perforation screw on the fork arm of the bottom of described L shaped crank, the rear portion of braking iron wedge also is provided with corresponding hole, screw rod connects the screw on L shaped crank and the braking iron wedge, on the screw rod between braking iron wedge and the L shaped crank, be provided with spring, be used to adjust height and degree of dip and position, whereabouts after braking iron wedge is mentioned.
