The invention discloses an elevator brake shoe gap adjusting method and an adjusting device thereof.The adjusting method comprises the steps that a displacement sensor used for detecting the abrasion loss of a brake shoe is installed on an elevator brake body, and the displacement sensor is connected with a PLC; detecting the distance L0 between a brake head of the brake and a probe of the displacement sensor by using the displacement sensor when the brake brakes, and setting the L0 as a reference value; the device is simple in structural design and convenient to use, the high-precision induction type displacement sensor is used for detecting the gap value of the brake shoe in real time and feeding back the gap value to the PLC till the gap of the brake shoe meets the safety range specified in the coal mine safety regulation, the purpose of full-automatic adjustment of the gap of the brake shoe is achieved, and the practicability is high. And when the abrasion loss of the brake shoe exceeds a certain value, a system alarm can be given, so that the brake shoe is replaced in time, and the safety and reliability of the elevator in the braking process are improved.
