Description

Technical Field

[0001] This utility model relates to the technical field of lifting pipes for oil drilling equipment, specifically a lifting pipe device for oil drilling equipment. Background Technology

[0002] Oil drilling refers to the process of drilling a cylindrical borehole of a certain diameter downwards or to one side at a pre-selected location on the surface after discovering an oil-bearing block through exploration, using specialized equipment and technology, and reaching the underground oil and gas layer. Currently, the commonly used drilling method is to use drilling rigs and other equipment to break up the rocks at the bottom of the well. After drilling, it is necessary to hoist the drilling pipes and other equipment. The most commonly used hoisting device is the hoisting pipe hoisting device.

[0003] The existing pipe hoisting device uses a combination structure of upper and lower clamps. During use, the pipe can be directly clamped between the upper and lower clamps. At this time, the hook plate is engaged inside the L-shaped plate to hoist the pipe. However, the clamp can only clamp pipes of one size. Since pipes come in different sizes, the pipe hoisting device cannot clamp pipes of different sizes. When the pipe size is different, the pipe hoisting device needs to be replaced, resulting in low flexibility and practicality of the device. Utility Model Content

[0044] Oil drilling refers to the process of drilling a cylindrical borehole of a certain diameter downwards or to one side at a pre-selected location on the surface after discovering an oil-bearing block through exploration, using specialized equipment and technology, and reaching the underground oil and gas layer. Currently, the commonly used drilling method is to use drilling rigs and other equipment to break up the rocks at the bottom of the well. After drilling, it is necessary to hoist the drilling pipes and other equipment. The most commonly used hoisting device is the hoisting pipe hoisting device.

[0045] In related technologies, because pipes come in different sizes, the pipe lifting device cannot clamp pipes of different sizes. When the pipe size is different, the pipe lifting device needs to be replaced, resulting in low flexibility and practicality of the pipe lifting device.

[0046] To address some of the problems in related technologies, this application provides a pipe hoisting device for oil drilling equipment. When it is necessary to clamp and fix the pipe, the first arc-shaped clamping plate 21 is pushed towards one side of the pipe by the drive component 12, so that the first arc-shaped clamping plate 21 squeezes and fixes the pipe. At the same time, according to the size of the pipe, the protrusion 251 is pressed, so that the second arc-shaped clamping plate 22 extends out due to the elasticity of the first spring 24. The pipe is wrapped and fixed by the extended parts of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] Combination Figures 1-3This application provides a lifting pipe device for oil drilling equipment, including a device body 1. The device body 1 includes: a drive assembly 12 disposed on the top inner side of a support frame 11; a lifting assembly 13 disposed at the bottom of the drive assembly 12; and a clamping assembly 2 disposed at the bottom of the lifting assembly 13. The clamping assembly 2 includes: a first arc-shaped clamping plate 21 disposed at the bottom of the lifting assembly 13; a second arc-shaped clamping plate 22 penetrating through the first arc-shaped clamping plate 21; a support block 23 disposed at one end of the second arc-shaped clamping plate 22 and located inside the first arc-shaped clamping plate 21; a first spring 24 disposed between the support block 23 and the first arc-shaped clamping plate 21; and a locking assembly 25 penetrating through the outer side wall of the first arc-shaped clamping plate 21.

[0049] In use, the lifting assembly 13 drives the first arc-shaped clamping plate 21 to move downward, so that the first arc-shaped clamping plate 21 is located outside the pipe. The driving assembly 12 pushes the first arc-shaped clamping plate 21 to move to one side of the pipe, so that the first arc-shaped clamping plate 21 squeezes and fixes the pipe. At the same time, depending on the size of the pipe, the locking assembly 25 is released, so that the second arc-shaped clamping plate 22 extends out due to the elasticity of the first spring 24. The extended parts of the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22 wrap and fix the pipe, so that the arc-shaped clamping plate can clamp and fix pipes of different sizes, increasing the flexibility and practicality of the lifting pipe device for oil drilling equipment. After fixing, the second arc-shaped clamping plate 22 is fixed by the locking assembly 25, and the lifting assembly 13 lifts the fixed pipe.

[0050] Specifically, the drilling equipment is a drilling rig. The working principle is that under atmospheric pressure, the circulating fluid flows from the sedimentation tank through the return water channel along the annular gap of the wellbore to the bottom of the well. At this time, the rotary table drives the drill pipe, which drives the drill bit to rotate and drill. The negative pressure established by the mud pump draws the debris and mud into the inner cavity of the drill pipe, and then rises to the swivel, and is discharged into the sedimentation tank by the mud pump. The settled circulating fluid continues to flow into the wellbore. This process is repeated continuously, forming a reverse circulation drilling operation. This section is not shown in the attached drawings of the instruction manual.

[0051] In some embodiments, the locking component 25 includes: a protrusion 251 disposed on the support block 23 and penetrating the support block 23; a slot 252 that mates with the protrusion 251 is provided on the outer side wall of the first arc-shaped clamping plate 21; a second spring 253 is disposed between the protrusion 251 and the support block 23. By pressing the protrusion 251, the protrusion 251 retracts into the interior of the first arc-shaped clamping plate 21, thereby moving the second arc-shaped clamping plate 22. When the support block 23 moves to the slot 252 at a predetermined position, the protrusion 251 is subjected to the rebound force of the second spring 253, causing the protrusion 251 to insert into the slot 252, thereby engaging and fixing the first arc-shaped clamping plate 21 and the second arc-shaped clamping plate 22.

[0052] In some embodiments, a limiting plate 254 is provided between the protrusion 251 and the second spring 253 and is located inside the support block 23 to limit the protrusion 251 and prevent the protrusion 251 from detaching from the support block 23.

[0053] In some embodiments, an anti-slip pad 26 is provided on the inner side of the first arc-shaped clamping plate 21. This increases the anti-slip properties of the first arc-shaped clamping plate 21 when clamping the pipe.

[0054] In some embodiments, the drive assembly 12 includes: a motor 121 disposed on the inner top of the support frame 11; a bidirectional threaded rod 122 disposed at the output end of the motor 121; and a moving block 123 symmetrical to the outer side of the bidirectional threaded rod 122, which is driven to rotate by the motor 121. The rotating bidirectional threaded rod 122 drives the first arc-shaped clamping plate 21 to move toward one side of the pipe through the moving block 123, so that the first arc-shaped clamping plate 21 squeezes and fixes the pipe.

[0055] In some embodiments, the lifting assembly 13 includes: an electric push rod 131 disposed at the bottom of the moving block 123; a first telescopic tube 132 disposed on the outside of the electric push rod 131; and a second telescopic tube 133 disposed at one end of the first telescopic tube 132 and located at the bottom of the moving block 123. The electric push rod 131 drives the second telescopic tube 133 to rise and fall through the first telescopic tube 132, thereby controlling the two sets of first arc-shaped clamping plates 21 that clamp the pipe to rise and fall simultaneously.

[0056] Specifically, the electric actuator 131 is model GX-DC / E10. Its working principle is that it uses an electric motor as power, and through gear reduction or worm gear, it drives a lead screw nut to convert the rotational motion of the electric motor into the linear motion of the actuator along the guide rail. The forward and reverse rotation of the electric motor is used to realize the reciprocating forward and backward motion of the actuator. The corresponding principle structure is not shown in the attached diagram.

[0057] In some embodiments, a slider 124 is provided on the top of the movable block 123, and a groove 125 is provided on the support frame 11 to cooperate with the slider 124, so that the movable block 123 is slidably connected to the support frame 11, supporting the movable block 123, increasing the stability of the movable block 123 in moving left and right, and preventing the movable block 123 from rotating with the bidirectional threaded rod 122.

[0058] In some embodiments, the bottom of the support frame 11 is provided with casters 14 to facilitate the movement of the lifting pipe device for the oil drilling equipment.
