Description

Technical Field

[0001] The utility model belongs to the technical field of drill rods, in particular to a quick-detachable drill rod shackle device. Background Art

[0002] Drill pipe is a threaded steel pipe used to connect the surface equipment of a drilling rig to the drilling and grinding equipment or bottom-hole assembly at the bottom of the well. The purpose of the drill pipe is to transport drilling mud to the drill bit and to raise, lower, or rotate the bottom-hole assembly together with the drill bit.

[0003] In order to make the connection between the existing drill rod and the power head more stable, the power head and the drill rod are mostly connected by bolts. Although this connection method can make the connection between the drill rod and the power head more stable, the drill rod needs to be frequently disassembled and assembled during actual use. Therefore, the bolt method will greatly increase labor costs and greatly increase the labor intensity of workers, and further reduce work efficiency. Therefore, a quick-release drill rod detachment device is urgently needed to improve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a quick-release drill pipe shackle device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a quick-release drill rod shackle device, comprising a power head for driving the drill rod, a fixed sleeve for the quick-release drill rod, and a sliding sleeve, wherein a connecting rod is fixedly connected between the top surface of the fixed sleeve and the bottom of the power head;

[0006] The side wall of the fixed sleeve is symmetrically penetrated with mounting holes, and a partition is fixedly installed longitudinally inside the mounting hole, and a sliding rod is installed through the side wall of the partition for horizontal sliding, and a push block is fixedly installed on the side of the sliding rod close to the outer wall of the fixed sleeve, and a clamping block is fixedly installed on the side of the sliding rod close to the inner wall of the fixed sleeve;

[0007] A push spring is fixedly installed between the push block and the partition, and the push spring is slidably sleeved to the outer side of the slide rod;

[0008] The sliding sleeve is slidably connected to the outer side of the fixed sleeve, and two fixing blocks are symmetrically fixedly installed on the inner wall of the sliding sleeve. The outer wall of the fixed sleeve is symmetrically provided with two L-shaped grooves that match the fixing blocks.

[0009] Preferably, a screw rod is installed through the thread of the side wall of the sliding sleeve, and a thread groove is provided on the outer wall of the fixing sleeve corresponding to the screw rod.

[0010] Preferably, one end of the two push blocks extending to the outside of the mounting hole is arranged in an arc shape.

[0011] Preferably, a damping pad is fixedly bonded to the outer wall of the fixing block, and the outer wall of the damping pad is slidably fitted to the inner wall of the L-shaped groove.

[0012] Preferably, two limiting blocks are symmetrically fixedly mounted on the side wall of the push block, and two limiting grooves are symmetrically formed on the inner wall of the mounting hole.

[0013] Preferably, the two limiting blocks fixedly mounted on the side wall of the push block are respectively slidably connected to the inside of two limiting grooves opened on the inner wall of the mounting hole.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] The quick-release drill pipe shackle device benefits from the arrangement of the fixed sleeve, the sliding sleeve, the mounting hole, the push block, the sliding rod and the clamping block. After the drill pipe is inserted into the fixed sleeve and the upper end of the drill pipe is connected to the power head, the two clamping blocks are aligned with the clamping grooves provided on the drill pipe. The sliding sleeve is pressed down along the outer side of the fixed sleeve. When the side wall of the sliding sleeve contacts the two push blocks, the two push blocks are relatively pushed to move into the mounting hole and the clamping blocks fixed at their ends are pushed by the sliding rod to be clamped into the inside of the clamping grooves provided on the side wall of the drill pipe, thereby achieving a fixed connection between the fixed sleeve and the drill pipe.

[0016] The quick-release drill pipe shackle device benefits from the arc-shaped arrangement of the two push blocks extending to the outside of the mounting hole, so that when the sliding sleeve contacts the push blocks, the push blocks are relatively pushed into the mounting hole.

[0017] The quick-release drill pipe shackle device benefits from the arrangement of a push spring between the partition plate and the push block. When the two push blocks are squeezed by the sliding sleeve, the push spring is compressed. When the sliding sleeve moves upward until the sliding sleeve is offset from the two push blocks, the push spring loses the external force and returns to its initial state. The push spring then pulls the sliding rod and the block out of the slot provided on the side wall of the drill pipe.

[0018] The quick-release drill pipe shackle device benefits from the arrangement of the fixing blocks on the inner wall of the sliding sleeve and the L-shaped grooves on the outer wall of the fixing sleeve. When the sliding sleeve is sleeved onto the outer wall of the fixing sleeve, the two fixing blocks are aligned with the L-shaped grooves and slid into the interior of the L-shaped grooves. When the fixing blocks move to the transverse grooves of the L-shaped grooves, the sliding sleeve is rotated to limit the sliding sleeve to the outside of the fixing sleeve through the fixing blocks.

[0019] Compared with the prior art, the quick-release drill rod shackle device can quickly disassemble and install the drill rod, thereby reducing the labor intensity of workers and further improving the disassembly and assembly efficiency of the drill rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0030] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0031] like Figures 1 to 5The main structure of the quick-release drill pipe breaker device shown in the figure is a power head 1 for driving the drill pipe, a fixed sleeve 3 for the quick-release drill pipe, and a sliding sleeve 10. The sliding sleeve 10 is slidably connected to the outside of the fixed sleeve 3. A connecting rod 2 is fixedly connected between the top surface of the fixed sleeve 3 and the bottom of the power head 1.

[0032] When the cam 5 is in the closed position, the cam 5 is in the closed position, and the cam 5 is in the closed position, so that the cam 5 can be fixed on the cam 5 by the cam 5. When the cam 5 is in the closed position, the cam 5 is in the closed position, and the cam 5 is fixed on the cam 5 by the cam 5.

[0033] A push spring 9 is fixedly installed between the push block 7 and the partition 5, and the push spring 9 is slidably sleeved to the outside of the slide rod 6. Thanks to the arrangement of the push spring 9 between the partition 5 and the push block 7, when the two push blocks 7 are squeezed by the sliding sleeve 10, the push spring 9 will be compressed. When the sliding sleeve 10 moves upward until the sliding sleeve 10 is offset from the two push blocks 7, the push spring 9 will lose the external force and return to its initial state and pull the slide rod 6 and the block 8 out of the slot opened on the side wall of the drill pipe through the push spring 9;

[0034] The sliding sleeve 10 is slidably sleeved to the outside of the fixed sleeve 3, and two fixing blocks 11 are symmetrically fixedly installed on the inner wall of the sliding sleeve 10. Two L-shaped grooves 12 are symmetrically opened on the outer wall of the fixed sleeve 3 and match the fixing blocks 11. Thanks to the setting of the fixing blocks 11 on the inner wall of the sliding sleeve 10 and the L-shaped grooves 12 on the outer wall of the fixed sleeve 3, when the sliding sleeve 10 is sleeved to the outer wall of the fixed sleeve 3, the two fixing blocks 11 are aligned with the L-shaped grooves 12 and slide into the inside of the L-shaped grooves 12. When the fixing blocks 11 move to the horizontal grooves of the L-shaped grooves 12, the sliding sleeve 10 is rotated to limit the sliding sleeve 10 to the outside of the fixed sleeve 3 through the fixing blocks 11.

[0035] A screw 13 is installed through the thread of the side wall of the sliding sleeve 10, and a thread groove 14 is opened on the outer wall of the fixed sleeve 3 corresponding to the screw 13. When the sliding sleeve 10 is clamped into the L-shaped groove 12 opened on the side wall of the fixed sleeve 3, the end of the screw 13 will correspond to the thread groove 14. At this time, the screw 13 is rotated to make it clamped into the inside of the thread groove 14, so that the sliding sleeve 10 and the fixed sleeve 3 can be further fixed.

[0036] The two push blocks 7 extend to one end of the outside of the mounting hole 4 and are arc-shaped. Thanks to the arc-shaped side of the two push blocks 7 extending to the outside of the mounting hole 4, when the sliding sleeve 10 contacts the push block 7, the push block 7 will be relatively pushed to move into the mounting hole 4.

[0037] The outer wall of the fixed block 11 is fixedly bonded with a damping pad, and the outer wall of the damping pad slides and fits the inner wall of the L-shaped groove 12. The damping pad can effectively increase the friction between the fixed block 11 and the inner wall of the L-shaped groove 12, thereby further improving the stability of the fixed block 11 in the L-shaped groove 12.

[0038] Two limit blocks 15 are symmetrically fixedly installed on the side wall of the push block 7, and two limit grooves are symmetrically opened on the inner wall of the mounting hole 4. The two limit blocks 15 fixedly installed on the side wall of the push block 7 are respectively slidably connected to the inside of the two limit grooves opened on the inner wall of the mounting hole 4. The limit blocks 15 can effectively limit the sliding direction of the push block 7, and at the same time further improve the stability of the push block 7 when sliding.

[0039] How it works

[0040] When using the quick-release drill pipe shackle device, the drill pipe to be installed is first passed through the fixing sleeve 3 from the bottom of the fixing sleeve 3 and connected to the power head 1. When the slot opened on the side wall of the drill pipe is opposite to the block 8 slidably installed on the inner wall of the fixing sleeve 3, the sliding sleeve 10 is then pressed downward to make it slide onto the outer wall of the fixing sleeve 3. When the sliding sleeve 10 contacts the push block 7 extending to the outside of the fixing sleeve 3, and the side wall of the push block 7 is inclined, the push block 7 is slid toward the inside of the mounting hole 4 and the sliding rod 6 fixedly installed on the side wall of the push block 7 pushes the block 8 fixedly installed at its end to be clamped into the inside of the slot opened on the side wall of the drill pipe, and at the same time, the push spring 9 is compressed, so as to achieve fixation between the fixing sleeve 3 and the drill pipe. At the same time, the sliding sleeve 10 is pressed down, and the two fixing blocks 11 installed on the inner wall of the sliding sleeve 10 are aligned with the two L-shaped grooves 12 opened on the outer wall of the fixing sleeve 3, and the fixing blocks 11 are made to slide into the L-shaped grooves 12. When the fixing blocks 11 slide to the horizontal grooves of the L-shaped grooves 12, the sliding sleeve 10 is rotated to achieve limited fixation between the fixing sleeve 3 and the sliding sleeve 10, and the screw 13 on the side wall of the sliding sleeve 10 will be opposite to the thread groove 14 opened on the outer wall of the fixing sleeve 3. At this time, the screw 13 is rotated to make its thread screwed into the thread groove 14, so as to further improve the installation stability between the fixing sleeve 3 and the sliding sleeve 10. When the drill rod needs to be disassembled, the drill rod can be quickly disassembled by simply reversing the above action.
