Description

Technical Field

[0002] Anchor holes are drilled for installing anchor bolts or cables during anchoring projects on bridge rock, unstable rock, and building components. Anchor hole drilling equipment is a key piece of equipment for anchor bolt support, affecting the accuracy of the anchor hole's orientation, depth, and diameter, as well as the quality of anchor bolt installation. It also involves the operator's personal safety, labor intensity, and working conditions.

[0003] Because the anchor holes are constructed at an inclined angle and the construction environment is harsh, positioning the drilling equipment presents significant challenges. Existing drilling equipment used for bridge anchor holes requires a lengthy positioning process before use, which slows down the construction progress. Furthermore, the positioning of the drilling equipment affects the accuracy and shape of the subsequently drilled rock anchor holes, negatively impacting the overall anchor cable construction. This can range from delaying the construction schedule to causing safety accidents; therefore, the positioning step of the drilling equipment cannot be ignored. Summary of the Invention

[0042] Please see Figure 1 This application provides a method for installing a drilling rig for drilling anchor holes, the drilling rig being used to drill anchor holes on the front anchor face. The installation method includes the following steps (steps S10, S20, S30, S40, S50, S60, and S70):

[0043] Step S10: Place the drilling rig at the corresponding position at the borehole opening for initial alignment.

[0044] The drilling rig has tracks for moving it back and forth and for supporting it on a working face. The working face can be a steel panel of a support platform, and it is parallel to the horizontal plane. The front anchor face and the working face have an angle greater than 0°. In one embodiment, the inclination angle of the anchor hole is 37°, then the angle between the front anchor face and the working face is 53°.

[0045] Specifically, a crane can be used to lift the drilling rig to the corresponding position at the borehole opening, or the crane can lift the drilling rig to the support platform and then the drilling rig will move to the corresponding position at the borehole opening on its own.

[0046] Step S20: Place the drilling attitude correction device under the drilling rig.

[0047] The drilling posture correction device includes a base plate 2, a rotating plate 3, and a translating plate 4 arranged from bottom to top. The base plate 2, the rotating plate 3, and the translating plate 4 are all parallel to the working surface. The rotating plate 3 can rotate relative to the base plate 2 about a vertically extending axis, and the translating plate 4 can move left and right (along the horizontal direction X) relative to the rotating plate 3. The track is placed on the translating plate 4.

[0048] Specifically, the drilling rig is equipped with outriggers that can extend and retract vertically. Step S20 specifically includes:

[0049] Step S201: Extend the outriggers to support the drilling rig on the working face, and separate the tracks from the working face;

[0050] Step S202: Move the drilling attitude correction device to below the drilling rig;

[0051] Step S203: Retract the outriggers so that the tracks come into contact with the translation plate 4.

[0052] In step S201, the distance between the track and the working face is greater than the height of the drilling posture correction device, so that the drilling posture correction device can be moved to below the drilling rig.

[0053] like Figure 4 As shown, the drilling posture correction device also includes at least two parallel channel steels 1 located below the base plate 2, with the base plate 2 fixedly connected to the channel steels 1. The channel steels 1 are used to contact the working surface. The lower surface of the base plate 2 is fixedly connected to the upper surface of the channel steels 1. This drilling posture correction device uses the channel steels 1 as a support. When the drilling posture correction device needs to be moved, the channel steels 1 can be connected to a moving mechanism (such as a pulley, traction rope, etc.), thereby facilitating the convenient and rapid movement of the drilling posture correction device to the required position.

[0054] Specifically, in step S20, the moving mechanism is connected to the channel steel 1, and the moving mechanism is used to move the drilling posture correction device to below the drilling rig.

[0055] In this embodiment, multiple channel steels 1 are arranged horizontally, with their extension direction parallel to the horizontal direction X. The thickness of the channel steel 1 is 50mm~70mm, preferably 60mm. The thickness of the base plate 2, the rotating plate 3, and the translation plate 4 can be equal, ranging from 15mm to 25mm, preferably 20mm.

[0056] Step S30: Drive the rotating plate 3 to rotate the drill rig, so that the drill rod axis of the drill rig is parallel to the axis of the anchor hole.

[0057] In this embodiment, the upper surface of the substrate 2 is in contact with the lower surface of the rotating plate 3. The substrate 2 and the rotating plate 3 are connected by a rotation drive mechanism 8, which drives the rotating plate 3 to rotate relative to the substrate 2 about a vertically extending axis. Accordingly, step S30 includes: operating the rotation drive mechanism 8 to rotate the rotating plate 3 relative to the substrate 2.

[0058] like Figure 2 and Figure 4As shown, the base plate 2 and the rotating plate 3 are rotatably connected at their centers by a rotating shaft 5. The rotating shaft 5 extends vertically in the Y direction, and its bottom is fixedly connected to the channel steel 1, so that the rotating plate 3 rotates around the axis of the rotating shaft 5. The base plate 2 has a first opening (not shown) at its center for accommodating the rotating shaft 5, and the rotating plate 3 has a second opening (not shown) at its center for accommodating the rotating shaft 5. The dimensions of both the first and second openings are equal to the dimensions of the rotating shaft 5. Both the first and second openings are cylindrical. In a specific embodiment, the diameter of the rotating shaft 5 is 80mm to 120mm, preferably 100mm.

[0059] Specifically, the translation plate 4 has a third opening 63 at its center, and the top of the rotating shaft 5 has a cap 51 located within the third opening 63. The size of the third opening 63 is larger than the size of the cap 51. The lower surface of the cap 51 is in contact with the upper surface of the rotating plate 3, and the diameter of the cap 51 is 130mm~170mm, preferably 150mm. The upper surface of the cap 51 is aligned with the upper surface of the translation plate 4, thus preventing interference with the drilling machine on the translation plate 4. The third opening 63 is cylindrical, and the difference between its diameter and the diameter of the cap 51 is greater than the distance the translation plate 4 can move horizontally in the X direction, ensuring that the rotating shaft 5 does not interfere with the movement of the translation plate 4. The diameter of the third opening 63 is 950mm~1050mm, preferably 1000mm.

[0060] like Figure 3 As shown, the rotary drive mechanism 8 includes: a central shaft 81, rotating angle irons 82, and a first lead screw 84. Four central shafts 81 are fixed to the rotary plate 3. The four central shafts 81 are located at the four vertices of a first rectangle. Four rotating angle irons 82 are rotatably connected to the base plate 2. Four rotating angle irons 82 are located at the four vertices of a second rectangle, the second rectangle having the same width as the first rectangle, and the length of the second rectangle being greater than the length of the first rectangle. One end of the first lead screw 84 is connected to the central shaft 81 via a bushing 83. The first lead screw 84 passes through and is connected to the rotating angle irons 82, and the length of the first lead screw 84 extending beyond the rotating angle irons 82 is adjustable. By adjusting the lengths of the four first lead screws 84 extending beyond the four rotating angle irons 82 respectively, the rotary plate 3 can be rotated to the desired angle, and the rotary plate 3 drives the translation plate 4 and the drill on the translation plate 4 to rotate together.

[0061] Preferably, the adjustable length of the first lead screw 84 is configured to allow the rotating plate 3 to rotate ±10° relative to the base plate 2, thereby enabling fine adjustment of the drilling rig angle.

[0062] Step S40: Drive the translation plate 4 to move the drill left and right, so that the drill rod axis of the drill and the anchor hole axis are in the same vertical plane.

[0063] In this embodiment, the upper surface of the rotating plate 3 is in contact with the lower surface of the translation plate 4. The rotating plate 3 and the translation plate 4 are connected by a translation drive mechanism 9, which drives the translation plate 4 to move horizontally (X) relative to the rotating plate 3. Accordingly, step S40 includes: operating the translation drive mechanism 9 to move the translation plate 4 left and right relative to the rotating plate 3.

[0064] like Figure 2 As shown, preferably, both the substrate 2 and the rotating plate 3 are rectangular. The widths of the substrate 2, the rotating plate 3, and the translation plate 4 are equal, ranging from 2300mm to 2500mm, preferably 2400mm. The length of the substrate 2 is greater than the length of the rotating plate 3, and the centers of the substrate 2 and the rotating plate 3 are aligned. The length of the substrate 2 is 3900mm to 4100mm, preferably 4000mm. The length of the rotating plate 3 is 3200mm to 3400mm, preferably 3300mm.

[0065] Specifically, the length of the translation plate 4 is less than the length of the rotating plate 3, and the centers of the translation plate 4 and the rotating plate 3 are aligned. The length of the translation plate 4 is 2700mm~2900mm, preferably 2800mm. The translation plate 4 has notches 65 at its four vertices to avoid the rotation drive mechanism 8 and prevent interference with the rotation of the rotating plate 3.

[0066] like Figure 1 As shown, the translation plate 4 has two fourth openings 64 located on both sides of the third opening 63. A limiting pin 7 is fixed on the rotating plate 3, extending into the fourth opening 64. The fourth opening 64 has a predetermined distance in the horizontal direction X, and the limiting pin 7 can move within the fourth opening 64 along the horizontal direction X. The predetermined distance is 550mm~650mm, preferably 600mm. The diameter of the limiting pin 7 is 110mm~130mm, preferably 120mm. The width of the fourth opening 64 is equal to the diameter of the limiting pin 7.

[0067] In this embodiment, the translation drive mechanism 9 includes: a first connecting member 91, a second connecting member 92, and a second lead screw 93. The first connecting member 91 is fixed to the side of the translation plate 4. The second connecting member 92 is fixed to the side of the rotating plate 3. One end of the second lead screw 93 is connected to the first connecting member 91, and the second lead screw 93 passes through and connects to the second connecting member 92. The length of the second lead screw 93 extending beyond the second connecting member 92 is adjustable. By adjusting the lengths of the four second lead screws 93 extending beyond the second connecting member 92, the translation plate 4 can be translated to the desired position, and the translation plate 4 drives the drilling rig to translate together.

[0068] Preferably, the adjustable length of the second lead screw 93 is configured to allow the translation plate 4 to move 400mm relative to the rotating plate 3, thereby enabling fine adjustment of the drilling rig's position in the horizontal X direction.

[0069] Step S50: Remove the drilling attitude correction equipment.

[0070] Specifically, in step S50, the moving mechanism is connected to the channel steel 1, and the moving mechanism is used to move the drilling posture correction device out from under the drilling rig.

[0071] In this embodiment, step S50 specifically includes:

[0072] Step S501: Extend the outriggers to support the drilling rig on the working face, and separate the tracks from the translation plate 4;

[0073] Step S502: Remove the drilling attitude correction device from under the drilling rig;

[0074] Step S503: Retract the outriggers to bring the tracks into contact with the working surface.

[0075] Step S60: Drive the crawler to move the drilling rig back and forth, so that the axis of the drill rod of the drilling rig coincides with the axis of the anchor hole.

[0076] In steps S30 and S40, a drilling posture correction device is used to fine-tune the drilling rig so that the drill rod axis is parallel to the anchor hole axis and the drill rod axis and the anchor hole axis are in the same vertical plane. Therefore, the crawler drives the drilling rig to move back and forth, thus adjusting the drilling rig until the drill rod axis coincides with the anchor hole axis. Using a drilling posture correction device can greatly optimize the drilling rig adjustment process, improve adjustment efficiency, and save construction time.

[0077] Step S70: Fix the drilling rig to the working face.

[0078] Specifically, step S70 includes welding the drilling rig and the working face together with a limiting steel plate, wherein the limiting steel plate limits the track.

[0079] The installation method for drilling anchor holes provided in this embodiment involves, after initial alignment, placing the drilling posture correction device below the drilling rig, driving the rotating plate 3 to rotate the drilling rig so that the drill rod axis of the drilling rig is parallel to the axis of the anchor hole; driving the translation plate 4 to move the drilling rig left and right so that the drill rod axis of the drilling rig and the axis of the anchor hole are in the same vertical plane; after removing the drilling posture correction device, driving the crawler to move the drilling rig back and forth so that the drill rod axis of the drilling rig coincides with the axis of the anchor hole; finally, fixing the drilling rig to the working face, which can quickly and effectively adjust the drilling rig body to be aligned with the axis of the designed hole (anchor hole).

[0080] The drilling posture correction device provided in this embodiment weighs approximately 3.8 tons. It can conveniently and quickly fine-tune the angle and position of large drilling rigs, aligning the rig body with the axis of the designed anchor hole, ensuring a deviation of no more than 2 mm (measured with a total station), and guaranteeing that the drilling inclination deviation does not exceed 0.1° (measured with a hole positioning instrument). By setting a rotary drive mechanism 8 between the base plate 2 and the rotary plate 3, the rotary plate 3 can be driven to rotate relative to the base plate 2 around a vertically extending axis, thereby making the drill rod axis of the drilling rig placed on the drilling posture correction device parallel to the axis of the designed hole. By setting a translation drive mechanism 9 between the rotary plate 3 and the translation plate 4, the translation plate 4 can be driven to move relative to the rotary plate 3 in the horizontal direction X, thereby making the drill rod axis of the drilling rig and the axis of the designed hole lie in the same vertical plane. Therefore, this drilling posture correction device can conveniently and quickly adjust the posture of the drilling rig.
