Abstract
Description
Technical Field

[0002] Drilling operations have wide applications in industries such as geological surveys and environmental sampling. During the drilling process, the drill pipe holder is an important wellhead tool, primarily used to clamp the drill pipe and prevent it from slipping within the hole. The performance of the drill pipe holder directly affects the overall performance of the drilling rig and the quality of the borehole.

[0036] Figure 6 This is a schematic diagram of the overall structure of the top cover of this application. In a specific embodiment of this application, as shown... Figure 6 and combined Figure 1 As shown, the drill pipe holder also includes a top cover 400, which includes a cylindrical body 401, a hollow cylindrical structure, and is disposed in the receiving space. The central axis of the cylindrical body 401 coincides with the central axis of the clamping space so that the drill pipe can pass through. A pair of hanging ears 402 and 403 are symmetrically disposed on the outer side wall of the end of the cylindrical body 401. The hanging ears 402 are disposed corresponding to the slips 201, and the hanging ears 403 are disposed corresponding to the slips 202. The hanging ears 402 abut against the clamping part 2012 of the slips 201, and the hanging ears 403 abut against the clamping part 2022 of the slips 202.

[0038] In other embodiments of this application, such as Figure 1 and Figure 2As shown, the drill pipe holder also includes a positioning sleeve 500, which is disposed on the side of the top cover 400 opposite to the top plate 105; the positioning sleeve 500 includes a through hole, the central axis of which coincides with the central axis of the cylindrical body 401, so that the drill pipe can pass through.
[0039] In actual use, if it is necessary to clamp drill rods with a larger outer diameter, the positioning sleeve 500 can be replaced as needed.
[0040] In other embodiments of this application, such as Figure 2 As shown, the drill pipe holder also includes a drive assembly 600, which is used to drive the top cover 400 away from or towards the top plate 105. The drive assembly 600 includes a pair of hydraulic cylinders 601 and 602. The hydraulic cylinder 601 is disposed in the space enclosed by the first side plate 101, the second side plate 102, the first partition 103 and the top plate 105. The hydraulic cylinder 602 is disposed in the space enclosed by the first side plate 101, the second side plate 102, the second partition 104 and the top plate 105.
[0041] In the above embodiments, specifically, the hydraulic cylinder 601 includes: a cylinder barrel 6011 connected to the top plate 105; a piston rod 6012 passing through the top plate 105, one end of which is connected to the cover body 404 of the top cover 400, and the other end is disposed inside the cylinder barrel 6011, and the piston rod 6012 can reciprocate relative to the cylinder barrel 6011; the hydraulic cylinder 602 includes: a cylinder barrel 6021 connected to the top plate 105; a piston rod 6022 passing through the top plate 105, one end of which is connected to the cover body 404 of the top cover 400, and the other end is disposed inside the cylinder barrel 6021, and the piston rod 6022 can extend and retract relative to the cylinder barrel 6021; when the piston rod 6012 and the piston rod 6022 extend and retract, they drive the top cover 400 away from or closer to the top plate 105.
[0042] The working principle of this application is as follows: In the initial state of the drill pipe holder, hydraulic cylinders 601 and 602 are retracted, the top cover 400 is close to the top plate 105, and the lugs 402 and 403 respectively press the slips 201 and 202. The slips 201 and 202 are located at the end of the housing 100 away from the top plate 105. The alloy block 2013 of the slip 201 and the alloy block 2023 of the slip 202 are clamped, and the springs 301 and 302 are in the extended state.
[0043] Scenario 1: Connecting two drill rods, hydraulic cylinders 601 and 602 apply pressure, extending piston rods 6012 and 6022, lifting the top cover 400. The top cover 400 moves the positioning sleeve 500 away from the top plate 105. The lugs 402 and 403 of the top cover 400 disengage from the clamping parts 2012 and 2022 of the slip 201 and slip 202, respectively. At this time, springs 301 and 302 contract, respectively driving slips 201 and slip 202 to move in the first direction (closer to the top plate 105). At this time, the plane of alloy block 2013 and the plane of alloy block 2023... As the distance between the planes increases (the clamping space increases), the drill rod is placed into the clamping space through the positioning sleeve 500. Hydraulic cylinders 601 and 602 release pressure, and piston rods 6012 and 6022 retract, causing the top cover 400 to move downwards. The top cover 400 then moves the positioning sleeve 500 closer to the top plate 105. At this time, the pressure of hydraulic cylinders 601 and 602 is not completely released. Lugs 402 and 403 respectively press the clamping parts 2012 and 2022 of slip 201 and slip 202, respectively. Alloy blocks 2013 and 2023 work together to press the drill rod. In addition, under the action of the drill rod's own weight, slips 201 and slips 202 continue to move away from the top plate 105, meaning the heavier the drill rod, the greater the clamping force.
[0044] The second scenario: After disassembling the two drill rods, hydraulic cylinders 601 and 602 are pressurized, extending piston rods 6012 and 6022, lifting the top cover 400. The top cover 400 moves the positioning sleeve 500 away from the top plate 105. The lugs 402 and 403 of the top cover 400 disengage from the clamping parts 2012 and 2022 of the slips 201 and 202, respectively. At this time, springs 301 and 302 contract, respectively driving slips 201 and 202 to move in the first direction (closer to the top plate 105). At this point, the plane of alloy block 2013 and the plane of alloy block 2023... As the distance between them increases (the clamping space increases), the drill rod is extended into the clamping space from the opposite direction of the positioning sleeve 500. Hydraulic cylinders 601 and 602 release pressure, and piston rods 6012 and 6022 retract, causing the top cover 400 to move downwards. The top cover 400 then moves the positioning sleeve 500 closer to the top plate 105. At this time, the pressure of hydraulic cylinders 601 and 602 is not completely released. Lugs 402 and 403 respectively press the clamping parts 2012 and 2022 of slip 201 and slip 202, respectively. Alloy blocks 2013 and 2023 work together to press the drill rod. In addition, under the action of the drill rod's own weight, slips 201 and slips 202 continue to move away from the top plate 105, that is, the heavier the drill rod, the greater the clamping force.
