Embodiment 1

[0030] Such as figure 1 , figure 2 As shown, the present invention provides a device for measuring the rotational speed and excitation frequency of an eccentric shaft of an audio drilling rig, including a gear 1, a Hall gear sensor 3, a pulse signal acquisition module 4 and a display module 5, and the gear 1 is connected to the eccentric shaft, so that After the eccentric shaft rotates, it will drive the gear 1 to rotate. The Hall gear sensor 3 is arranged on one side of the gear 1 through the mounting seat 2 and is opposite to the tooth top surface of the gear 1; the Hall gear sensor 3 is connected to the pulse signal acquisition module 4 through communication, and the pulse signal acquisition module 4 communicates with the display module 5 connected.

[0031] Its working principle is as follows: during the operation of the audio drilling rig, the eccentric shaft of the audio drilling rig drives the gear 1 to perform a rotary motion. Every time the gear 1 rotates a tooth, ...

Abstract

The invention provides a device and method for measuring the rotating speed and excitation frequency of an audio frequency drilling machine, the device comprises a gear, a Hall gear sensor, a pulse signal acquisition module and a display module, the gear is connected to an eccentric shaft, and the Hall gear sensor is arranged on one side of the gear and is opposite to the tooth top surface of the gear; the Hall gear sensor is in communication connection with the pulse signal acquisition module, and the pulse signal acquisition module is in communication connection with the display module. By means of the device and the method, the rotating speed of the eccentric shaft and the excitation frequency of the vibrating body can be monitored in real time in the environments of high-frequency vibration, severe impact and the like, and rotating speed information can be uploaded to a programmable controller or other main control computers in real time to be processed and recorded with other data in real time.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the rotational speed and excitation frequency of an eccentric shaft of a drilling rig. Background technique [0002] The power head is the core component of the audio drilling rig, in which the rotational speed of the eccentric shaft and the excitation frequency of the vibrating body are the core parameters of the audio drilling rig in the geological drilling process. Measurement accuracy, real-time, and reliability are particularly important. [0003] Since the vibration frequency and acceleration of the vibrating body of the power head are far beyond the use conditions of ordinary sensors, they cannot meet the use requirements. Therefore, there is a need for a rotating speed and excitation frequency measuring device that can be used in severe environments such as high vibration and field construction. Contents of the invention [0004] In order to overcome the problems in the ...
