Description

Technical Field

[0001] This utility model belongs to the field of drilling anti-deviation technology, specifically a geological drilling anti-deviation device. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It often uses drilling rigs to drill holes in the strata to identify and classify the strata below the surface and to take samples along the depth of the hole. Drilling is one of the most widely used exploration methods in engineering geological investigation. It can obtain deep geological data. However, because the shaking generated by the drilling equipment during drilling can cause the drill bit to deviate, drilling anti-deviation devices are needed for assistance.

[0003] The publication number CN202022868395.0 discloses a geological drilling anti-deviation device. This technology discloses that "the base plate is moved to the working site, holes are drilled at the working site according to the installation position of the expansion bolts, the base plate is installed and fixed at the working site using expansion bolts, the box is installed above the connecting block using bolts, the drilling device is placed into the box, the knob is rotated to drive the threaded rod to rotate, and the rotation of the threaded rod drives the clamping plates to move towards each other to clamp and fix the drilling device."

[0004] Although the above-mentioned device has a certain anti-deviation function, it still has some shortcomings in use: 1. It does not have an adjustment function and cannot be well adapted to drill rods of different lengths, resulting in poor applicability; 2. Since the drill rod rotates during operation, the clamping of the drill rod directly through the clamping plate can easily restrict the operation of the drill rod; 3. The anti-deviation effect is poor.

[0017] To make the technical means, creative features, achieved objectives, and effects of this utility model readily understandable, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Furthermore, it should be understood that after reading the teachings of this utility model, those skilled in the art can make various modifications or alterations to this utility model, and these equivalent forms also fall within the scope defined in this application.

[0018] like Figure 1-6 As shown, the geological drilling anti-deviation device of this utility model includes a vertical plate 1. Two mounting plates 2 are arranged vertically on the front of the vertical plate 1. The two mounting plates 2 are connected to the vertical plate 1 through an adjustment component. Each mounting plate 2 is detachably connected to a support cylinder 3 through a connecting component. Each support cylinder 3 is rotatably connected to a support sleeve 4 through a bearing. Mounting components are provided at the four corners of the rear of the vertical plate 1. Supporting components are provided on both sides of the bottom surface of the vertical plate 1.

[0019] like Figure 1 , Figure 3 and Figure 5 As shown, the adjustment assembly includes: an adjustment screw 5; a strip groove 6 is formed on the front of the vertical plate 1; the adjustment screw 5 is rotatably connected in the strip groove 6; the upper and lower ends of the adjustment screw 5 are provided with opposite threads; the upper and lower ends of the adjustment screw 5 are threadedly connected to moving blocks 7; the moving blocks 7 are located in the strip groove 6 and can slide along the moving blocks 7; a first fixing rod 8 is fixedly connected to the front of each moving block 7; and the front ends of the two first fixing rods 8 are fixedly connected to the mounting plate 2.

[0020] Specifically, rotating the adjusting screw 5 causes the two moving blocks 7 to move relative to each other (or in opposite directions) along the adjusting screw 5 because the upper and lower ends of the adjusting screw 5 have opposite threads. The movement of the moving blocks 7 causes the first fixed rod 8 to move, and the movement of the first fixed rod 8 causes the mounting plate 2 to move, thereby adjusting the distance between the two mounting plates 2 so as to adjust the distance between the two support sleeves 4 and meet the support and anti-skewing requirements of drill rods of different lengths.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, two T-shaped grooves 9 are provided on the front of the vertical plate 1, and a T-shaped slider 10 is slidably connected in each T-shaped groove 9. A second fixing rod 11 is fixedly connected to the front of each T-shaped slider 10, and the front end of each second fixing rod 11 is fixedly connected to the corresponding mounting plate 2.

[0022] Specifically, the T-shaped slider 10 can slide up and down along the T-shaped groove 9, thereby driving the second fixed rod 11 to move. With the cooperation of the second fixed rod 11 and the T-shaped slider 10, the mounting plate 2 can be limited and supported, thus ensuring the stability of the mounting plate 2.

[0023] like Figure 1 , Figure 2 and Figure 6 As shown, the connecting assembly includes: a connecting block 12, which is fixedly connected to the support cylinder 3, and fastening bolts 13 are provided on both sides of the connecting block 12, which are threadedly connected to the mounting plate 2.

[0024] Specifically, by tightening the bolts 13, the connecting block 12 and the mounting plate 2 can be quickly disassembled and installed, thereby enabling the installation and disassembly of the support cylinder 3 and the support sleeve 4. Furthermore, the corresponding support cylinder 3 and support sleeve 4 can be quickly replaced according to the size of the drill rod, thus improving the applicability of this device.

[0025] like Figure 1 and Figure 4 As shown, the mounting assembly includes an L-shaped mounting plate 14, which is fixedly connected to the vertical plate 1, and mounting holes 15 are provided on the L-shaped mounting plate 14.

[0026] Specifically, by fixing the L-shaped mounting plate 14 and opening the mounting hole 15 on the L-shaped mounting plate 14, the vertical plate 1 can be fixedly installed on the drilling rig to support the drill rod and prevent it from tilting, thus ensuring the accuracy of drilling.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the support assembly includes: a support sleeve 16, which is fixedly connected to the vertical plate 1, a support rod 17 is threadedly connected to the bottom end of the support sleeve 16, and a support base 18 is fixedly connected to the bottom end of the support rod 17.

[0028] Specifically, rotating the support base 18 can drive the support rod 17 to rotate along the support sleeve 16. Since the support rod 17 is threadedly connected to the support sleeve 16, the support rod 17 can move up and down along the support sleeve 16, thereby adjusting the height of the support base 18 to meet the support requirements at different heights, thus improving the stability of the vertical plate 1.

[0029] like Figure 1 and Figure 2 As shown, the bottom surface of the support base 18 is a rough surface.

[0030] Specifically, the bottom surface of the support base 18 is rough, which increases the friction of the support base 18 and ensures the stability of the support base 18.

[0031] Working principle: First, the vertical plate 1 is fixedly installed on the drilling machine through the L-shaped mounting plate 14. Then, the support base 18 is rotated, which can drive the support rod 17 to rotate along the support sleeve 16. Since the support rod 17 is threadedly connected to the support sleeve 16, the support rod 17 can move up and down along the support sleeve 16, thereby adjusting the height of the support base 18 so that the support base 18 contacts the drilling machine to meet the support requirements at different heights, thereby improving the stability of the vertical plate 1. Then, depending on the length of the drill rod, rotate the adjusting screw 5. Since the upper and lower ends of the adjusting screw 5 have opposite threads, rotating the adjusting screw 5 can drive the two moving blocks 7 to move relative to each other (or in opposite directions) along the adjusting screw 5. The movement of the moving blocks 7 drives the first fixed rod 8 to move, and the movement of the first fixed rod 8 drives the mounting plate 2 to move, thereby adjusting the distance between the two mounting plates 2. The movement of the mounting plates 2 drives the support cylinder 3 and the support sleeve 4 to move, thereby adjusting the distance between the two support sleeves 4 to meet the support and anti-skewing requirements of drill rods of different lengths. Then the drill rod passes through the two support sleeves 4 and slides in contact with the inner wall of the support sleeve 4. Since the support sleeve 4 is rotatably connected to the support cylinder 3 through the bearing, it can drive the support sleeve 4 to rotate when the drill rod rotates, thereby supporting the drill rod and preventing it from deviating. At the same time, it can ensure the drilling operation of the drill rod and ensure the drilling accuracy.
