Embodiment 1

[0051] like Figure 1 to Figure 5 As shown in the figure, a device for controlling and measuring the drilling inclination of a steel rope impact drilling rig according to the present invention includes an inclination control ring 1 and a measuring disc 2. The annular section of the inclination control ring 1 is set horizontally, and the axis of the steel rope 3 is vertical. Straight through the center of the annular section of the inclination control ring 1, when the steel rope 3 contacts the inclination control ring 1, the inclination of the steel rope 3 is the maximum inclination required by the construction; 1. A limit control is formed for the inclination of the steel rope 3 to ensure that the inclination of the steel rope 3 is within the scope of the construction requirements, so as to ensure that the inclination of the drilling hole does not exceed the maximum inclination of the construction requirements, so as to ensure that the drilling construction does not affect the ...

Embodiment 2

[0063] This embodiment provides an inclination control method on the basis of Embodiment 1.

[0064] Using the inclination control method of the inclination control and measurement device, the inclination control method is as follows:

[0065] First, complete the setting of the steel wire hammer drill, at this time, the axes of the steel wire 3 and the hammer drill 6 are both vertically downward and collinear with the axis of the drill hole;

[0066] Then, the setting of the inclination control ring 1 is performed. At this time, the semi-circular ring a11 and the semi-circular ring b12 of the inclination control ring 1 are in the open state, and the central position of the inclination control ring 1 is adjusted through the threaded sleeve 42 and the connecting steel pipe 41 , to ensure that the axis of the steel rope 3 passes through the center of the inclination control ring 1;

[0067] Finally, the control of the inclination of the drilling rig is completed. When the axis o...

Embodiment 3

[0069] This embodiment provides an inclination measurement method on the basis of Embodiment 2

[0070] An inclination measurement method based on the inclination control method, the inclination measurement method is as follows:

[0071] When the inclination control ring 1 completes the control of the inclination, the measuring plate 2 is installed in the inclination control ring 1. At this time, the steel rope 3 is located in the measuring groove of the measuring plate 2, and the inclination of the steel rope 3 can be adjusted. Drive the measuring disc 2 to rotate in the inclination control ring 1, and at the same time the steel rope 3 can slide in the measuring groove;

[0072] Read the inclination offset distance d of the steel rope 3 at the inclination control ring 1 through the center distance mark 1 ;

[0073] Through the calculation of the vertical inclination ζ of the borehole, the deviation can be corrected in time according to the value of ζ.

Abstract

The invention discloses a steel rope impact type drilling machine drilling inclination control and measurement device and method.The device comprises an inclination control ring and a measurement disc, the annular section of the inclination control ring is horizontally arranged, the axis of a steel rope vertically penetrates through the center of the annular section of the inclination control ring, and when the steel rope makes contact with the inclination control ring, the inclination control ring is connected with the measurement disc; the gradient of the steel rope is the maximum gradient required by construction; the measuring disc is arranged in the inclination control ring, and the steel rope is arranged in a measuring part of the measuring disc. Firstly, a limiting space for limiting inclination of the steel rope is formed through the inclination control ring, it is guaranteed that the inclination of the steel rope does not exceed the maximum inclination required by construction, and therefore the inclination of a drilled hole is controlled; and secondly, while the inclination is controlled, the inclination amount of the steel rope is measured in real time through a measuring disc arranged in the inclination control ring, and then the inclination of the drilled hole at the moment is calculated and obtained through the inclination amount, so that a drilling machine is adjusted and rectified in time.

Description

technical field [0001] The invention relates to the technical field of drilling construction equipment, in particular to a device and method for controlling and measuring the inclination of a steel wire impact drilling rig. Background technique [0002] In geotechnical engineering, impact drill is a commonly used hole making equipment. It is widely used in the construction of pile foundations, anti-seepage walls, underground diaphragm walls and other underground projects. It has the advantages of wide application range and low construction cost. The impact drill uses the main rod to connect the steel wire rope to connect the impact drill bit to impact the hole. During the construction process, it is necessary to measure the inclination of the drilling hole to prevent the inclination of the drilling hole from exceeding the design requirements. However, as the hole-making depth increases, the inclination of the impact hole-forming is not easy to control, and it is also difficu...
