[0025] See also Figure 1The embodiment of the present application provides an installation method of a drilling rig for drilling anchor holes, wherein the drilling rig is used to drill anchor holes on a front anchor surface. The installation method comprises the following steps (step S10, step S20, step S30, step S40, step S50, step S60 and step S70): Step S10: placing the drilling machine at a position corresponding to the hole opening and performing preliminary alignment.

[0026] The drilling rig has a crawler, and the crawler is used to drive the drilling rig to move forward and backward and support the drilling rig on a working surface. The working surface can be a steel panel of a support platform, and the working surface is parallel to a horizontal plane. The front anchor surface and the working surface have an angle greater than 0. In one embodiment, the inclination angle of the anchor hole is 37°, and the angle between the front anchor surface and the working surface is 53°.

[0027] Specifically, a crane may be used to hoist the drilling rig to a position corresponding to the hole opening, or after the crane hoists the drilling rig to a support platform, the drilling rig automatically moves to a position corresponding to the hole opening.

[0028] Step S20: placing the drilling posture correction device under the drilling rig.

[0029] The drilling posture correction device includes a base plate 2, a rotating plate 3 and a translation plate 4 arranged from bottom to top. The base plate 2, the rotating plate 3 and the translation plate 4 are all parallel to the working surface. The rotating plate 3 can rotate relative to the base plate 2 around a vertically extending axis, the translation plate 4 can move left and right (along the horizontal direction X) relative to the rotating plate 3, and the crawler is placed on the translation plate 4.

[0030] Specifically, the drilling rig is provided with legs that can be extended up and down. The step S20 specifically includes: Step S201: Extend the outriggers to support the drilling rig on the working surface, and separate the crawler from the working surface; Step S202: moving the drilling posture correction device to below the drilling rig; Step S203: retract the legs to make the track contact with the translation plate 4.

[0031] In step S201, the distance between the crawler and the working surface is greater than the height of the drilling posture correction device, so that the drilling posture correction device can be moved under the drilling rig.

[0032] like Figure 4As shown, the drilling posture correction device also includes at least two parallel channel steels 1 located below the base plate 2, and the base plate 2 is 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. The drilling posture correction device is provided with the channel steels 1 as support, and when the drilling posture correction device needs to be moved, the channel steels 1 can be connected to a moving mechanism (such as a ground pulley, a traction rope, etc.), so as to facilitate the drilling posture correction device to be moved to a desired position quickly and conveniently.

[0033] Specifically, in step S20, the moving mechanism is connected to the channel steel 1, and the drilling posture correction device is moved to the bottom of the drilling rig using the moving mechanism.

[0034] In this embodiment, a plurality of channel steels 1 are arranged horizontally, and their extension direction is parallel to the horizontal direction X. The thickness of the channel steel 1 is 50 mm to 70 mm, preferably 60 mm. The thickness of the base plate 2, the rotating plate 3 and the translation plate 4 can be equal, and can be 15 mm to 25 mm, preferably 20 mm.

[0035] Step S30: driving the rotating plate 3 to drive the drilling rig to rotate, so that the axis of the drill rod of the drilling rig is parallel to the axis of the anchor hole.

[0036] In this embodiment, the upper surface of the substrate 2 is in contact with the lower surface of the rotating plate 3, and the substrate 2 and the rotating plate 3 are connected via a rotation drive mechanism 8, and the rotation drive mechanism 8 is used to drive the rotating plate 3 to rotate relative to the substrate 2 around 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.

[0037] like Figure 2 and Figure 4 As shown, the base plate 2 and the rotating plate 3 are rotatably connected at the center through a rotating shaft 5, the rotating shaft 5 extends along the vertical direction Y, and the bottom of the rotating shaft 5 is fixedly connected to the channel steel 1, so that the rotating plate 3 rotates around the axis of the rotating shaft 5. A first opening (not shown) for accommodating the rotating shaft 5 is provided at the center of the base plate 2, and a second opening (not shown) for accommodating the rotating shaft 5 is provided at the center of the rotating plate 3. The size of the first opening and the size of the second opening are both equal to the size of the rotating shaft 5. The first opening and the second opening are both cylindrical. In a specific embodiment, the diameter of the rotating shaft 5 is 80 mm to 120 mm, preferably 100 mm.

[0038] Specifically, a third opening 63 is provided at the center of the translation plate 4, and a top cap 51 located in the third opening 63 is provided at the top of the rotating shaft 5, and the size of the third opening 63 is larger than the size of the top cap 51. The lower surface of the top cap 51 is in contact with the upper surface of the rotating plate 3, and the diameter of the top cap 51 is 130 mm to 170 mm, preferably 150 mm. The upper surface of the top cap 51 is aligned with the upper surface of the translation plate 4, so as not to interfere with the drilling rig on the translation plate 4. The third opening 63 is cylindrical, and the difference between its diameter and the diameter of the top cap 51 is greater than the distance that the translation plate 4 can move along the horizontal direction X, so that the rotating shaft 5 does not interfere with the movement of the translation plate 4. The diameter of the third opening 63 is 950 mm to 1050 mm, preferably 1000 mm.

[0039] like Figure 3 As shown, the rotary drive mechanism 8 includes: a central axis 81, a rotating angle iron 82 and a first lead screw 84. Four central axes 81 are fixed to the rotating plate 3. The four central axes 81 are located at the four vertices of the first rectangle. The four rotating angle irons 82 are rotatably connected to the base plate 2. The four rotating angle irons 82 are located at the four vertices of the second rectangle, the width of the second rectangle is equal to that of the first rectangle, and the length of the second rectangle is greater than the length of the first rectangle. One end of the first lead screw 84 is connected to the central axis 81 through a sleeve 83. The first lead screw 84 is penetrated and connected to the rotating angle iron 82, and the length of the first lead screw 84 extending from the rotating angle iron 82 is adjustable. By adjusting the lengths of the four first lead screws 84 extending from the four rotating angle irons 82 respectively, the rotating plate 3 can be rotated to the desired angle, and the rotating plate 3 drives the translation plate 4 and the drilling rig on the translation plate 4 to rotate together.

[0040] 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 to achieve fine adjustment of the drilling rig angle.

[0041] Step S40: driving the translation plate 4 to drive the drilling rig to move left and right, so that the axis of the drill rod of the drilling rig and the axis of the anchor hole are located in the same vertical plane.

[0042] In this embodiment, the upper surface of the rotating plate 3 is in contact with the lower surface of the translation plate 4, and the rotating plate 3 and the translation plate 4 are connected via a translation drive mechanism 9, and the translation drive mechanism 9 is used to drive the translation plate 4 to move relative to the rotating plate 3 along the horizontal direction X. 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.

[0043] like Figure 2As shown, preferably, the substrate 2 and the rotating plate 3 are both rectangular. The widths of the substrate 2, the rotating plate 3 and the translation plate 4 are equal, which are 2300mm~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~4100mm, preferably 4000mm. The length of the rotating plate 3 is 3200mm~3400mm, preferably 3300mm.

[0044] Specifically, the length of the translation plate 4 is less than that 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 2700 mm to 2900 mm, preferably 2800 mm. Notches 65 are provided at the four vertices of the translation plate 4 to avoid the rotation drive mechanism 8 and avoid interference with the rotation of the rotating plate 3.

[0045] like Figure 1 As shown, the translation plate 4 is provided with two fourth openings 64 located on both sides of the third opening 63, and a limiting pin 7 extending into the fourth opening 64 is fixed on the rotation plate 3. The fourth opening 64 has a predetermined distance in the horizontal direction X, and the limiting pin 7 can move in the fourth opening 64 along the horizontal direction X. The predetermined distance is 550 mm to 650 mm, preferably 600 mm. The diameter of the limiting pin 7 is 110 mm to 130 mm, preferably 120 mm. The width of the fourth opening 64 is equal to the diameter of the limiting pin 7.

[0046] 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 is connected to the second connecting member 92 through the second connecting member 92. The length of the second lead screw 93 extending from the second connecting member 92 is adjustable. By adjusting the lengths of the four second lead screws 93 extending from the second connecting member 92, the translation plate 4 can be translated to a desired position, and the translation plate 4 drives the drilling rig to translate together.

[0047] Preferably, the adjustable length of the second lead screw 93 is configured to allow the translation plate 4 to move 400 mm relative to the rotation plate 3, thereby achieving fine adjustment of the position of the drilling rig in the horizontal direction X.

[0048] Step S50: Evacuate the drilling posture correction device.

[0049] Specifically, in step S50, the moving mechanism is connected to the channel steel 1, and the drilling posture correction device is moved out from under the drilling rig using the moving mechanism.

[0050] In this embodiment, the step S50 specifically includes: Step S501: Extend the outriggers to support the drilling rig on the working surface, and separate the crawler from the translation plate 4; Step S502: moving the drilling posture correction device out from under the drilling rig; Step S503: retract the legs to make the crawler track contact with the working surface.

[0051] Step S60: driving the crawler to drive the drilling rig to move forward and backward, so that the axis of the drill rod of the drilling rig coincides with the axis of the anchor hole.

[0052] Among them, since the drilling posture correction device is used in step S30 and step S40, the drilling rig is fine-tuned until the axis of the drill rod is parallel to the axis of the anchor hole and the axis of the drill rod and the axis of the anchor hole are located in the same vertical plane, the crawler drives the drilling rig to move forward and backward, that is, the drilling rig can be adjusted until the axis of the drill rod coincides with the axis of the anchor hole. Using the drilling posture correction device can greatly optimize the adjustment process of the drilling rig, improve the adjustment efficiency, and save construction time.

[0053] Step S70: Fix the drilling rig on the working surface.

[0054] Wherein, step S70 specifically includes: welding the drilling rig and the working surface through a limiting steel plate, and the limiting steel plate limits the crawler track.

[0055] The installation method of the drilling rig for drilling anchor holes provided in this embodiment is as follows: after preliminary alignment, the drilling posture correction device is placed under the drilling rig, and the rotating plate 3 is driven to drive the drilling rig to rotate so that the axis of the drill rod of the drilling rig is parallel to the axis of the anchor hole; the translation plate 4 is driven to drive the drilling rig to move left and right so that the axis of the drill rod of the drilling rig and the axis of the anchor hole are located in the same vertical plane; after evacuating the drilling posture correction device, the crawler is driven to drive the drilling rig to move forward and backward so that the axis of the drill rod of the drilling rig coincides with the axis of the anchor hole; finally, the drilling rig is fixed to the working surface, and the drilling rig body can be quickly and effectively adjusted to align with the axis of the designed hole (anchor hole).

[0056] The drilling posture correction device provided in the embodiment of the present application weighs about 3.8 tons. It can quickly and conveniently fine-tune the angle and position of a large drilling rig, so that the drilling rig body is aligned with the axis of the designed anchor hole, so that the deviation between the two does not exceed 2 mm (measured by a total station), and ensure that the drilling inclination angle deviation of the drilling rig does not exceed 0.1° (measured by a hole locator). By setting a rotary drive mechanism 8 between the base plate 2 and the rotating plate 3, the rotating plate 3 can be driven to rotate relative to the base plate 2 around the vertically extending axis, so that the drill rod axis of the drilling rig placed on the drilling posture correction device can be parallel to the axis of the designed hole; by setting a translation drive mechanism 9 between the rotating plate 3 and the translation plate 4, the translation plate 4 can be driven to move in the horizontal direction X relative to the rotating plate 3, so that the drill rod axis of the drilling rig and the axis of the designed hole are located in the same vertical plane. Therefore, the drilling posture correction device can quickly and conveniently adjust the posture of the drilling rig.
