Description

Technical Field

[0001] This utility model relates to the field of drilling engineering technology, and more specifically, it relates to a drilling anti-deviation support device for drilling engineering. Background Technology

[0002] Drilling or exploration utilizes deep drilling mechanical engineering technology to extract natural resources from the earth's bottom or seabed, or to obtain geological profiles and physical samples for experiments to obtain relevant data. In drilling sampling work, it is often necessary to take multiple samples in the same straight direction. Drilling equipment is generally mounted on a support device, but the support devices in the current technology are generally difficult to adjust the position of the drilling equipment along a straight direction, which makes the drilling equipment prone to deviation.

[0003] A search revealed a drilling anti-deviation device for drilling engineering, with announcement number CN221990313U. The device includes an anti-deviation platform installed in the mounting groove, with an anti-deviation hole extending through the top of the platform. The drilling equipment is fixed to the second threaded hole on the top of the mounting plate using bolts. The drill bit of the drilling equipment is inserted into the anti-deviation hole. When the drill bit moves downwards first, the anti-deviation hole can limit and prevent deviation of the drill bit.

[0004] However, the anti-deviation platform and the support platform in the aforementioned drilling anti-deviation device are fixedly connected by bolts, which makes it inconvenient to quickly replace the anti-deviation platform and reduces work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a drilling anti-deviation support device for drilling engineering. By rotating the lead screw, the L-shaped plate is driven to slide away from the U-shaped seat, so that the L-shaped plate is pulled out from the corresponding positioning groove, releasing the fixed limit on the anti-deviation platform. Rotating the anti-deviation platform causes the anti-deviation hole that matches the corresponding drill bit to rotate to directly below the drill bit, realizing the rapid replacement of the anti-deviation hole and improving work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drilling anti-deviation support device for drilling engineering includes a support frame and a sliding frame slidably mounted on the support frame; the sliding frame includes a fixed plate; an installation hole is provided at an eccentric position on the surface of the sliding frame; an annular groove is provided on the inner circumferential side of the installation hole; an anti-deviation platform is rotatably mounted inside the installation hole; the anti-deviation platform includes a rotating plate that rotatably engages with the installation hole; a plurality of anti-deviation holes of different sizes are uniformly provided on the surface of the rotating plate; an annular rail that rotatably engages with the annular groove is fixed on the circumferential side of the rotating plate; a fixing ring is fixed on the top of the rotating plate; a plurality of positioning grooves are uniformly provided on the circumferential side of the fixing ring; a U-shaped seat is fixed on the surface of the fixed plate; an L-shaped plate that is inserted into and engages with the corresponding positioning groove is slidably mounted through the side of the U-shaped seat.

[0008] The present invention is further configured such that: a drilling device is fixedly mounted on the surface of the U-shaped seat by fastening bolts; a clearance hole coaxial with the fixed plate is opened on the surface of the U-shaped seat; the drill bit on the drilling device is inserted into and engaged with the corresponding anti-deviation hole; a lead screw is rotatably provided on the side of the U-shaped seat; the lead screw is threadedly engaged with the L-shaped plate.

[0009] The present invention is further configured such that: the support frame includes two L-shaped seats arranged parallel to each other; positioning holes are evenly opened on the surface of the L-shaped seats; and a first anchor rod is inserted into each of the positioning holes.

[0010] The present invention is further configured such that: a guide rod is symmetrically fixed between the two L-shaped seats; a sliding sleeve is slidably disposed on the guide rod; a sliding rod is symmetrically fixed between the two sliding sleeves; and a sleeve that slides with the sliding rod is symmetrically fixed to the bottom surface of the fixing plate.

[0011] The present invention is further configured such that: ear plates are symmetrically fixed on the periphery of the fixed plate; and a second anchor rod with a hollow internal structure is slidably disposed through the surface of the ear plate.

[0012] The present invention is further configured such that: a plurality of sliding holes are evenly provided on the inner wall of the second anchor rod; an insert rod is slidably disposed inside the sliding hole; a ball head is fixed at the end of the insert rod; and a return spring sleeved on the corresponding second anchor rod is fixedly connected between the ball head and the inner wall of the second anchor rod.

[0013] The present invention is further configured such that: a threaded sleeve is fixed to the top of the second anchor rod; a screw is rotatably provided inside the threaded sleeve; a vertical rod is fixed to the bottom of the screw; and a tapered rod is fixed to the bottom of the vertical rod.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses a rotating lead screw to drive an L-shaped plate to slide away from the U-shaped seat, causing the L-shaped plate to be pulled out of the corresponding positioning groove, releasing the fixed limit on the anti-deviation platform. Rotating the anti-deviation platform causes the anti-deviation hole that matches the corresponding drill bit to rotate to directly below the drill bit, realizing the rapid replacement of the anti-deviation hole and improving work efficiency.

[0016] 2. This utility model uses a first anchor rod to fix the L-shaped seat to the designated ground. The sliding sleeve slides along the sliding rod, thereby driving the sliding frame and drilling equipment to slide synchronously. The sliding frame slides along the guide rod, driving the drilling equipment to slide synchronously. After the drilling position is adjusted, the sliding frame is fixed and limited by the second anchor rod, which meets the needs of multi-point drilling and improves the practicality of the device.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0027] Example 1, please refer to Figure 1-6 The present invention provides the following technical solution:

[0028] Specifically, it refers to a drilling anti-deviation support device for drilling engineering, comprising a support frame 1 and a sliding frame 2 slidably mounted on the support frame 1; the sliding frame 2 includes a fixed plate 3; an installation hole 4 is provided at an eccentric position on the surface of the sliding frame 2; an annular groove 5 is provided on the inner circumferential side of the installation hole 4; an anti-deviation platform 6 is rotatably mounted inside the installation hole 4; the anti-deviation platform 6 includes a rotating plate 7 that rotatably engages with the installation hole 4; a plurality of anti-deviation holes 8 of different sizes are uniformly provided on the surface of the rotating plate 7; an annular rail 9 that rotatably engages with the annular groove 5 is fixed on the circumferential side of the rotating plate 7; a fixed ring 10 is fixed on the top of the rotating plate 7; a plurality of positioning grooves 11 are uniformly provided on the circumferential side of the fixed ring 10; a U-shaped seat 12 is fixed on the surface of the fixed plate 3; an L-shaped plate 13 that is inserted and engaged with the corresponding positioning groove 11 is slidably mounted through the side of the U-shaped seat 12.

[0029] Drilling equipment is fixedly mounted on the surface of the U-shaped seat 12 by fastening bolts; the surface of the U-shaped seat 12 has a clearance hole 14 coaxial with the fixed plate 3; the drill bit on the drilling equipment is inserted into the corresponding anti-deviation hole 8; a lead screw 15 is rotatably provided on the side of the U-shaped seat 12; the lead screw 15 is threadedly rotated with the L-shaped plate 13.

[0030] The specific application of this embodiment is as follows:

[0031] By rotating the lead screw 15, the L-shaped plate 13 is slid away from the U-shaped seat 12 until it is pulled out from the corresponding positioning groove 11, thus releasing the fixed limit on the rotating plate 7. Each set of positioning grooves 11 corresponds to a set of anti-deviation holes 8. Rotating the rotating plate 7 causes the matching anti-deviation hole 8 to rotate directly below the drill bit of the drilling equipment. Rotating the lead screw 15 in the opposite direction causes the L-shaped plate 13 to slide closer to the U-shaped seat 12 until it is inserted into the corresponding positioning groove 11, thus completing the fixed limit on the rotating plate 7 and enabling the rapid replacement of the anti-deviation hole 8, which improves work efficiency. After the anti-deviation hole 8 is replaced, the drill bit of the drilling equipment is lowered by controlling it to pass through the matching anti-deviation hole 8. The anti-deviation hole 8 can be used to limit the deviation of the drill bit of the drilling equipment.

[0032] Example 2, please refer to Figure 1-6 This second embodiment is an improvement on the first embodiment. Specifically, the support frame 1 includes two L-shaped seats 16 arranged in parallel with each other; positioning holes 30 are evenly opened on the surface of the L-shaped seats 16; and a first anchor rod is inserted into each positioning hole 30.

[0033] Guide rods 17 are symmetrically fixed between the two L-shaped seats 16; sliding sleeves 18 are slidably arranged on the guide rods 17; sliding rods 19 are symmetrically fixed between the two sliding sleeves 18; sleeves 20 that slide and cooperate with sliding rods 19 are symmetrically fixed on the bottom surface of the fixing plate 3.

[0034] Ear plates 21 are symmetrically fixed on the three sides of the fixed plate; a second anchor rod 22 with a hollow internal structure is slidably provided through the surface of the ear plate 21.

[0035] The inner wall of the second anchor rod 22 is evenly provided with several sliding holes 23; a rod 24 is slidably disposed inside the sliding hole 23; a ball head 25 is fixed at the end of the rod 24; a return spring 26 sleeved on the corresponding second anchor rod 22 is fixedly connected between the ball head 25 and the inner wall of the second anchor rod 22.

[0036] The top of the second anchor rod 22 is fixed with a threaded sleeve 27; a screw rod 28 is rotatably installed inside the threaded sleeve 27; a vertical rod 31 is fixed to the bottom of the screw rod 28; and a tapered rod 29 is fixed to the bottom of the vertical rod 31.

[0037] One specific application of this embodiment is:

[0038] By placing the drilling anti-deviation support device of this application in the designated drilling area, fixing the L-shaped seat 16 to the ground by the first anchor rod, sliding the sliding sleeve 18 along the guide rod 17 to drive the sliding frame 2 together with the drilling equipment to slide along the length direction of the guide rod 17, and sliding the sliding frame 2 along the sliding rod 19 to drive the drilling equipment to slide along the direction of the sliding rod 19, the drilling position can be adjusted.

[0039] After adjusting the drilling position, press the second anchor rod 22 downward along the ear plate 21 so that the second anchor rod 22 is inserted into the ground, thereby fixing and limiting the sliding frame 2 and improving the stability of the subsequent drilling process.

[0040] During the insertion of the second anchor rod 22 into the ground, each insertion rod 24 is housed inside the second anchor rod 22, and the corresponding return spring 26 is in normal condition. At the same time, the tapered rod 29 is placed above each set of ball heads 25. After the second anchor rod 22 is inserted into the ground, the screw 28 is rotated to rotate and descend along the corresponding threaded sleeve 27, thereby driving the vertical rod 31 at the bottom of the screw 28 to rotate and descend synchronously, which in turn drives the tapered rod 29 to rotate and descend synchronously. During the descent, the tapered rod 29 gradually squeezes each set of ball heads 25 until each set of ball heads 25 abuts against the circumferential side of the vertical rod 31. During this process, the return spring 26 is squeezed, and the insertion rod 24 is inserted into the soil, further improving the stability of the second anchor rod 22 insertion, that is, improving the stability of the sliding frame 2, and further improving the stability of the subsequent drilling process.
