Embodiment 1

[0065] According to the conditions defined above, the principle of the present invention is as follows. The personnel in the room first drill a detection hole 52 connected to point B in any direction with point A as the starting point. The center of the detection hole 52 outlet is set as point C, and Two points in the direction are set as point D and point E, and the lengths of AD and DE are known, and the distances between BD and BE are measured at the same time (marked as a and b respectively). Through geometrical solution, the equations 1 are obtained as follows, which can be Calculate the value of ∠BAC (denoted as θ), and it can be determined that point A, point B, point C, point D and point E are all on the same plane. On this plane, starting from point A, relative to the direction of AC The base hole 53 along the AB direction can be obtained by drilling at an angle of θ.

[0066] cos(β)=DE 2 +b 2 -a 2 / 2DE·b

[0067] AD+DE=AE

[0068] AB 2 = AE 2 +b 2 -2AE·b·cos(...

Embodiment 2

[0117] Such as Figure 19 with Figure 20 As shown, based on the above-mentioned principle and structure, the a-value and b-value can be measured respectively by sliding the first measuring device 33b along the axial direction of the measuring bracket 31 in two determined positions, which also meets the requirements of the above-mentioned geometric principle , while also eliminating the second measuring device 34b and the second measuring rod 34a.

[0118] Specifically, the measuring device also includes a sliding sleeve, and the second measuring rod 34a and the second measuring device 34b are canceled at the same time, the sliding sleeve moves axially along the measuring bracket 31, the sliding sleeve and the measuring bracket 31 have no relative movement in the circumferential direction, and the sliding sleeve moves along the measuring bracket 31. There are two limited positions for the axial movement of the bracket 31, which are respectively a position close to the first e...

Embodiment 3

[0122] Such as Figure 21 As shown, the geometric principle of Embodiment 1 and Embodiment 2 is to measure a value and b value at the same time or successively, and then calculate the θ angle. The θ angle can also be calculated by calculating the a value and the corresponding angle α. , the principle is as follows:

[0123] According to the conditions defined in this paper, the principle of the third embodiment of the present invention is as follows. The personnel in the room first use point A as the starting point to drill a detection hole 52 connected to point B in any direction, and the center of the detection hole 52 exit is set to point C. , take any point along the AC direction as point D, and the length of AD is known, respectively measure the distance of BD, denoted as a, through geometric solution, the equations 2 are obtained as follows, and the value of ∠BAC can be calculated (denoted as θ), it can be determined that point A, point B, point C and point D are all on...

Abstract

The invention discloses a device for drilling a hole at a set point and an application method thereof, belongs to the field of building projects and installation projections, and particularly relatesto the field of hole drilling of a building component. A drilling tool driven by a power machine is used for drilling a hole in the direction determined by a point A and a point B on the opposite surfaces of the building component; a first end of a main support is provided with a flange, and the intersection point between the face of the flange and the central line of the main support is a datum point; the main support is fixedly connected with the building component through a fastener; the main support is fixedly connected with the first end of the first support, a second end of the first support is fixedly connected with an angle adjusting device, and the power machine is fixedly connected with the angle adjusting device; the angle adjusting device adjusts and keeps the included angle between the axis of the drilling tool and the central line of the main support; a measuring device can measure the length feature value and the angle feature value at the same time; and the swinging plane between the central line of the main support and the central point of a target coupling and the swinging plane between the central line of the main support and the axis of the drilling tool is coplanar. By means of the device, the hole can be drilled at the set point of the building component precisely.

Description

technical field [0001] The invention belongs to the field of civil engineering and installation engineering, in particular to the field of drilling building components. Background technique [0002] In civil engineering, especially installation engineering, directional drilling of building components for laying pipelines has always been a difficult problem in the industry. Taking opening holes in walls as an example, it is usually vertical after determining the opening point on the inside or outside of the wall. Drill holes in the wall to form a through hole connecting the inside and outside of the wall. However, in actual operation, there are often areas that need to be avoided on the inside and outside of the wall, or the openings on the inside and outside of the wall have position requirements, and it is necessary to start from the inside of the wall. The existing technology can only rely on the construction personnel to estimate the angle of the drill bit on the inside o...
