The invention provides a tire locking brake for an electric power construction transfer vehicle. A fixed block and a sliding shaft of the tire locking brake are in clearance fit. The upper end of the sliding shaft is fixedly connected with a drive plate, and clamping supports used in pairs are hinged to the lower end of the sliding shaft. A sleeve is fixed to the upper end face of the drive plate, a telescopic rod with a handle is arranged in the sleeve, and a locking rotary knob is arranged at the upper end of the sleeve. A reset spring A is arranged between the two clamping supports, and reset springs B are connected between the two clamping supports and the lower end of the fixed block respectively. Upper limiting grooves and lower limiting grooves are sequentially formed in the side wall of a through hole in the vertical direction. At least two sets of upper limiting grooves and lower limiting grooves are evenly formed in the side wall of the through hole in the circumferential direction. A ball pin capable of matching the upper limiting grooves and the lower limiting grooves is arranged on the outer side wall of the sliding shaft, a radial mounting groove is formed in the outer side wall of the sliding shaft, and the ball pin is arranged in the radial mounting groove through a reset spring C. The brake can lock and unlock tires of the transfer vehicle.
