[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of inclination measurement device of rotary drilling rig drill rod, including bottom plate, baffle one fixed in the top of the bottom plate one end, baffle two rotationally connected in the inner cavity of the top of the bottom plate intermediate position, straight plate is fixedly covered in the outer circumferential surface one end of the baffle two, semicircular protractor is fixed in the top of the bottom plate in straight plate one end and flush adjusting mechanism is applied to the straight plate;

[0007] The flush adjusting mechanism includes rotating assembly and positioning assembly.

[0008] The rotating assembly includes a circular gear fixedly sleeved on the other end of the outer circumferential surface of the second baffle, a rack meshing with the bottom of the circular gear, a first threaded sleeve fixed to one end of the rack, a first threaded rod threadedly connected to one end of the first threaded sleeve, and a positioning shaft slidably inserted into the other end of the first threaded sleeve.

[0010] It is further worth noting that the positioning component includes connecting frames fixed to both sides of the straight plate, a second threaded rod rotatably connected to the top of the inner cavity of the two connecting frames, a sliding seat threaded to the outer circumferential surface of the second threaded rod, a limiting rod slidably inserted through the surface of the sliding seat, an abutting block disposed at one end of the sliding seat, and a sliding component acting on the abutting block.

[0011] Furthermore, it should be noted that the two abutting blocks are arranged in an arc shape on the side that is close to each other, and the two sides of the limiting rod are fixed to the inner wall of the connecting frame at the adjacent position.

[0012] In a preferred embodiment, the sliding component includes a third threaded rod that is threaded through and connected to one side of the sliding seat, and a support rod that is slidably inserted through and onto the other side of the sliding seat. One end of the third threaded rod is rotatably connected to the surface of the adjacent contact block, and one end of the support rod is fixed to the surface of the adjacent contact block.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art. Example 1

[0025] Please see Figures 1-5 This utility model provides a rotary drilling rod inclination measuring device, including a base plate 1, a baffle 2 fixed to one end of the top of the base plate 1, a baffle 5 rotatably connected to the inner cavity at the middle position of the top of the base plate 1, a straight plate 4 fixedly sleeved on one end of the outer periphery of the baffle 4, a semi-circular protractor 3 fixed to one end of the straight plate 4 at the top of the base plate 1, and a leveling adjustment mechanism acting on the straight plate 4.

[0026] The leveling adjustment mechanism includes a rotating component and a positioning component;

[0027] When adjusting the rotary drilling rod, the initial drilling angle is required. Then, a certain distance is left between the drill rod and the ground. The base plate 1 is moved to the end of the drill rod so that the drill rod is close to and in contact with the baffle 2. The angle of the straight plate 4 can be stably adjusted by the rotating component. With the help of the positioning component, it is easy to ensure that the straight plate 4 is adjusted to the same angle as the drill rod inclination.

[0028] Please see Figures 1-5 The rotating assembly includes a spur gear 6 fixedly sleeved on the other end of the outer peripheral surface of the baffle 2 5, a rack 7 meshing with the bottom of the spur gear 6, a first threaded sleeve 8 fixed to one end of the rack 7, a first threaded rod 9 threaded through and threaded to one end of the first threaded sleeve 8, and a positioning shaft 10 slidably inserted through and inserted into the other end of the first threaded sleeve 8. One side of the first threaded rod 9 is rotatably connected to the inner surface of the base plate 1, and the other end of the first threaded rod 9 passes through the base plate 1 and extends out of the outside of the base plate 1. Both sides of the positioning shaft 10 are fixed to the inner wall of the base plate 1.

[0029] When the angle of the straight plate 4 needs to be adjusted, the positioning shaft 10 can limit the movement trajectory of the first threaded sleeve 8, so that the first threaded sleeve 8 can only slide in the horizontal direction. Thus, when the first threaded rod 9 is rotated, the first threaded sleeve 8 can drive the rack 7 to move in the horizontal direction under the cooperation of the threaded structure between the first threaded sleeve 8 and the first threaded rod 9. Thus, under the meshing action between the rack 7 and the spur gear 6, the baffle 2 5 can drive the straight plate 4 to change angle. This makes it easy to adjust the angle of the straight plate 4. Furthermore, due to the limiting effect of the threaded structure between the first threaded sleeve 8 and the first threaded rod 9, the straight plate 4 can remain stable when rotated to various different angles.

[0030] Please see Figures 1-5 The positioning assembly includes connecting frames 12 fixed to both sides of the straight plate 4, a second threaded rod 13 rotatably connected to the top of the inner cavity of the two connecting frames 12, a sliding seat 14 threaded to the outer peripheral surface of the second threaded rod 13, a limiting rod 16 slidably inserted through the surface of the sliding seat 14, an abutment block 15 disposed at one end of the sliding seat 14, and a sliding component acting on the abutment block 15. The two abutment blocks 15 are arranged in an arc shape on the side that is close to each other, and the two sides of the limiting rod 16 are fixed to the inner wall of the adjacent connecting frame 12.

[0031] When the straight plate 4 is rotated, the two abutment blocks 15 can be positioned on both sides of the drill rod. The abutment blocks 15 can be adjusted to move in the front-back direction by the sliding component, so that the rotating rod can be positioned in the middle of the two abutment blocks 15. Then, by rotating the second threaded rod 13, since the external thread structures on both sides of the outer circumferential surface of the second threaded rod 13 are arranged in opposite directions, the sliding seat 14 can be limited by the adjacent position limiting rod 16 and cooperate with the corresponding position of the outer circumferential surface thread structure of the second threaded rod 13, so that the two abutment blocks 15 can move towards each other. When the two rotating straight plates 4 are adjusted to the corresponding angle, the abutment blocks 15 can be simultaneously clamped on the outer circumferential surface of the drill rod when they move towards each other, so that the inclination of the straight plate 4 after rotation can be kept flush with the inclination of the drill rod, thereby improving the accuracy of the drill rod inclination measurement.

[0032] Please see Figures 1-5 The sliding component includes a third threaded rod 17 that is threaded through and connected to one side of the sliding seat 14, and a support rod 18 that is slidably inserted into the other side of the sliding seat 14. One end of the third threaded rod 17 is rotatably connected to the surface of the adjacent abutment block 15, and one end of the support rod 18 is fixed to the surface of the adjacent abutment block 15.

[0033] Because the connection between the support rod 18 and the adjacent sliding seat 14 can limit the movement trajectory of the abutment block 15, when the third threaded rod 17 is rotated, it can extend horizontally under the cooperation of the threaded structure between the sliding seat 14 and the adjacent third threaded rod 17. Thus, under the connection between the third threaded rod 17 and the abutment block 15, the abutment block 15 can move horizontally. This allows the abutment block 15 to be adjusted to the front-back position after the angle of the straight plate 4 changes, so that the drill rod can be placed in the middle position of the two abutment blocks 15. Example 2

[0034] Reference Figures 1-5 As shown, the leveling adjustment mechanism also includes a leveling component, which includes a bubble level 11 fixed at one end of the base plate 1, casters 28 set at the four corners of the bottom of the base plate 1, sliding rods 27 slidably inserted at the four corners of the base plate 1, movable blocks 26 fixed at the top of the sliding rods 27, and vertical movement components acting on the movable blocks 26.

[0035] By observing the bubble level 11, it can be determined whether the base plate 1 is in a horizontal state. If it is not in a horizontal state, the semicircular protractor 3 is also not in a horizontal state, resulting in an error when measuring the inclination of the drill rod through the semicircular protractor 3. By using the vertical moving component at the adjacent position according to the inclination direction, the movable block 26 can be driven to move in the vertical direction, so that the sliding rod 27 can drive the universal wheel 28 to move in the vertical direction, thereby adjusting the base plate 1 to a horizontal state.

[0036] Reference Figures 1-5 As shown, the vertical moving component includes a rod groove 19 located on the top of the base plate 1 at one side of the sliding rod 27, a fourth threaded rod 20 rotatably connected inside the rod groove 19, a second threaded sleeve 21 threadedly connected to the middle position of the outer circumference of the fourth threaded rod 20, a connecting rod 22 hinged to the top of the second threaded sleeve 21, a rotating rod 23 rotatably connected to both ends of the base plate 1 near the rod groove 19, a first bevel gear 24 fixedly sleeved in the rotating rod 23 and embedded in the rod groove 19 at an adjacent position, and a second bevel gear 25 fixedly sleeved on one side of the outer circumference of the fourth threaded rod 20. The first bevel gear 24 and the second bevel gear 25 are meshed together, and the top of the connecting rod 22 is hinged to the adjacent movable block 26.

[0037] Rotating the rotating rod 23 causes the first bevel gear 24 to rotate, which in turn allows the fourth threaded rod 20 to rotate due to the meshing action between the first bevel gear 24 and the second bevel gear 25. Since the inner cavity of the rod groove 19 can act as a stop and limit the movement between the adjacent second threaded sleeves 21, the second threaded sleeve 21 can move horizontally under the action of the threaded structure between the second threaded sleeve 21 and the fourth threaded rod 20. This causes the connecting rod 22 to change angle, and the sliding rod 27 can cause the movable block 26 to move vertically under the action of contact with the inner wall of the base plate 1.
