Description

Technical Field

[0001] The utility model relates to the technical field of anti-deviation devices, and specifically relates to a drilling anti-deviation device. Background Technique

[0002] Drilling or exploration is a mechanical engineering technology using deep drilling. During the drilling process, without limitation, the drill rod is very likely to deviate under the influence of external factors such as rock formations, affecting the construction results. For example, the patent with the publication number CN217206359U discloses an anti-deviation device for drilling, including a base. A drilling hole is opened on the surface of the base, and a fixing frame is arranged on the upper surface of the base. A first support rod and a second support rod are fixedly connected to the surface of the fixing frame. A first slider is fixedly connected to the lower surface of the first support rod, and a second slider is fixedly connected to the lower surface of the second support rod. The surfaces of the first slider and the second slider are both slidably connected to the surface of the base. A first sliding rod is fixedly connected to the inner wall of the fixing frame, and fixing plates are symmetrically opened on the surface of the first sliding rod. This device limits the drill rod through the fixing frame and the fixing plates, thereby achieving an anti-deviation effect. However, this device can only prevent deviation of the vertically downward drill rod and cannot be used for drill rods at some special angles, and the application range of the device is relatively narrow.

[0003] Therefore, the utility model provides a drilling anti-deviation device. Content of the Utility Model

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a drilling deviation prevention device, including a bottom plate 1. A support frame 2 is fixed on the upper side of the bottom plate 1. An anti-deviation cylinder 4 is installed inside the support frame 2. Bearings 10 are installed on the circumferential side of the anti-deviation cylinder 4. Two rotating shafts 5 are installed between the bearings 10 and the support frame 2. Fixing plates 6 and sliding plates 7 are installed between the rotating shafts 5 and the support frame 2. Multiple anti-deviation structures are installed inside the anti-deviation cylinder 4. The anti-deviation structure includes a clamping plate 13 and a pressing plate 14. A damping block 12 is fixed between the clamping plate 13 and the pressing plate 14.

[0019] In this embodiment, a through hole 3 is opened inside the bottom plate 1. The inner diameter of the through hole 3 is the same as the outer diameter of the anti-deviation cylinder 4, and the through hole 3 is located directly below the anti-deviation cylinder 4. A plurality of telescopic rods 11 are fixed on the circumferential side of the anti-deviation cylinder 4. One end of the telescopic rod 11 is located inside the anti-deviation cylinder 4, and the end of the telescopic rod 11 located inside the anti-deviation cylinder 4 is fixedly connected to the clamping plate 13.

[0020] Specifically, when vertical downward drilling is required, the bottom plate 1 is fixed on the ground, and then the drilling rod is inserted into the anti-deviation cylinder 4. One end of the drilling enters the through hole 3, and then the telescopic rod 11 is stretched so that the pressing plate 14 contacts the drilling rod. Then, the length of the telescopic rod 11 is fixed, and then drilling can be carried out through the drilling rod. When the drilling rod is working, the drilling rod will generate large vibrations. At this time, the drilling rod presses the pressing plate 14, thereby pressing the damping block 12. The damping block 12 can play a shock-absorbing effect. At the same time, the clamping plate 13 and the pressing plate 14 limit the drilling rod to prevent the drilling rod from deviating.

[0021] The two rotating shafts 5 are respectively located on both sides of the anti-deviation cylinder 4. The rotating shafts 5 are fixedly connected to the bearings 10. One end of the rotating shaft 5 penetrates through the support frame 2 and is rotatably connected to the support frame 2.

[0022] Specifically, when rotary drilling is carried out, at this time, the anti-deviation cylinder 4 may rotate along with it. The rotating shaft 5 can play a role in reducing friction.

[0023] The rotating shaft 5 is fixedly connected to the fixing plate 6, and the fixing plate 6 is located on the side of the support frame 2 close to the anti-deviation cylinder 4. The rotating shaft 5 is slidably connected to the sliding plate 7, and the sliding plate 7 is located on the side of the support frame 2 far from the anti-deviation cylinder 4. A plurality of through grooves are opened inside the fixing plate 6, the sliding plate 7 and the support frame 2. Screws 8 are installed inside the through grooves. The two ends of the screw 8 are respectively located on the side surface of the fixing plate 6 and the side surface of the sliding plate 7, and nuts 9 are installed at both ends of the screw 8.

[0024] Specifically, when the anti-deviation cylinder 4 needs to be rotated, the nut 9 is rotated to remove the screw 8. At this time, the anti-deviation cylinder 4 can be rotated through the rotating shaft 5. When it is rotated to the appropriate angle, the screw 8 is inserted into the through groove to limit the anti-deviation cylinder 4, and then the screw 8 can be fixed through the nut 9, thereby fixing the anti-deviation cylinder 4, and inclined drilling can be carried out.

[0025] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
