Embodiment 1

[0061] Please refer to figure 1 , figure 1 It is a block diagram of the measurement and control device in embodiment 1. An on-line accurate measurement and control device for drilling rig angle. The measurement and control device includes a drilling rig body, a display screen 2, an inclination sensor 31; the display screen 2 is arranged on the operating table 7 of the drilling rig body; the inclination sensor 31 is placed On the drill arm 11 on the drill body; the inclination sensor 31 and the display screen 2 are connected by a cable; the inclination sensor 31 is used to measure the angle between the borehole and the horizontal plane.

[0062] What needs to be explained in this embodiment is that the inclination angle sensor 31 is designed to measure the inclination angle of the borehole, and the measurement is accurate, which overcomes the problem of inaccurate measurement of the borehole angle in the traditional technology.

Embodiment 2

[0064] Please refer to figure 2 , figure 2 It is a block diagram of the measurement and control device in the second embodiment. An on-line accurate measurement and control device for drilling rig angle. The measurement and control device includes a drilling rig body, a display screen 2, an azimuth angle sensor 32; the display screen 2 is arranged on an operating table 7 of the drilling rig body row; the azimuth angle sensor 32 is placed on the drill arm 11 on the drilling rig body, or the azimuth angle sensor is at any position of the rotating part of the lower gyrator of the drilling rig body; the azimuth angle sensor 32 is used to measure the azimuth angle of the borehole. In this embodiment, the azimuth angle sensor 32 is used to make the measurement azimuth more accurate, to ensure that the boreholes are evenly distributed, and the phenomenon of stringing holes is not easily caused.

[0065] What needs to be explained in this embodiment is that the azimuth sensor 32 is des...

Embodiment 3

[0067] Please refer to image 3 , image 3 It is a block diagram of the measurement and control device in the third embodiment. An on-line accurate measurement and control device for drilling rig angle, said measurement and control device includes a drilling rig body, a display screen 2, an inclination sensor 31, and an azimuth angle sensor 32; the display screen 2 is arranged on the operating table 7 of the drilling rig body row; The inclination angle sensor 31 and the azimuth angle sensor 32 are both placed on the drill boom 11 on the drilling rig body.

[0068] It should be noted in this embodiment that, in this embodiment, the inclination sensor 31 and the azimuth angle sensor are used together, so that the drilling position has a positioning effect.

Description

Technical field [0001] The invention relates to the technical field of drilling rig angles, in particular to a device and method for on-line accurate measurement and control of drilling rig angles. Background technique [0002] With the rapid development of economic construction, significant progress has been made in the field of engineering machinery technology. Among them, drilling rigs are mechanical equipment that drives drilling tools in any direction in geological exploration to obtain physical geological data. For example, in the process of underground coal mining, due to the complex and changeable coal seam occurrence conditions, major gas accidents often occur. Therefore, in order to prevent local gas safety accidents in coal mines and achieve effective gas extraction and utilization, it is necessary to use a drainage drill before excavation. Detecting holes are used to detect, release and utilize the gas in the mine to avoid the occurrence of gas explosion accidents. [...
