Abstract

The invention discloses a drilling machine rotating speed monitoring system, a control method and an application method, and relates to the field of coal mine machinery. The drilling machine rotating speed monitoring system comprises a rotating mechanism, a rotating speed sensor and a processor, wherein the rotating mechanism comprises a rotating disc, and N magnets are arranged on the rotating disc; the rotating speed sensor comprises a support and a sensor body, the support is vertically arranged at the bottom of the rotating mechanism, the sensor body is vertically arranged on the support, and the top end of the sensor body is opposite to the magnets of the rotating disc; and a rotating speed threshold value is set in the processor, and the processor is used for controlling the rotating speed of the rotating mechanism. According to the drilling machine rotating speed monitoring system, the rotating speed sensor is used for detecting the magnets to calculate the rotating speed of the rotating mechanism of a drilling machine, the structure is simple and easy to realize, meanwhile, the drilling machine rotating speed monitoring system can be used for monitoring the process of unscrewing a drill rod by double clamping devices, and the probability of drilling machine accidents in the screw thread dismounting process is reduced.

Description

technical field [0001] The invention relates to the field of coal mine machinery, in particular to a drilling rig rotation speed monitoring system, a control method and an application method. Background technique [0002] When the drilling rig is in the drilling construction process, it is necessary to adjust the speed of the equipment during drilling according to the drilling medium and the load of the drilling rig. The same automatic control drilling rig needs to maintain efficient operation during the drilling process. The speed and other parameters are collected, and the operating status of the equipment is automatically adjusted according to the parameter changes to achieve the maximum operating efficiency. [0003] A speed detection method is disclosed in the prior art, which includes a friction power generation module in the slewing mechanism, and a circuit board in the entire system to detect the power generation frequency and calculate the drilling tool speed accord...
