The hydraulic brake oil cylinder comprises an oil cylinder body, a piston and a guide screw, the piston and the guide screw are arranged in the oil cylinder body, one end of the guide screw is provided with a guide shaft, the other end of the guide screw is connected with a brake hand wheel, an oil pipe is arranged in the guide shaft, the guide screw is sleeved with the piston, and the oil pipe is connected with the brake hand wheel. A spring is arranged between the piston and the inner wall of the oil cylinder body, an emergency release oil port is formed in a cylinder cover at the front end of the oil cylinder body, and the emergency release oil port is communicated with an oil pipe. On the basis that the overall dimension and the weight of an original brake oil cylinder are not increased, the function of reducing the braking force capacity in emergency is achieved, the workload of operators in the emergency state is reduced, and the use safety of equipment is improved.
