Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, and particularly relates to a device for lifting, connecting and removing drill pipes of a drilling rig. Background Art

[0002] In the drilling field, operations such as lifting drill pipes, docking drill pipes, and removing drill pipes mainly rely on manual labor. In the process of lifting drill pipes, workers mainly climb up the tower through the handrails on the tower, buckle the sling on the upper end of the drill pipe, and rely on the power of the drilling rig to raise or lower the sling, so as to lift or lower the drill pipe, as Figure 1 shown. In the process of docking drill pipes and removing drill pipes, first use a spacer fork to fix the drill pipe entering the core hole, and then use a special long-arm wrench to loosen or tighten the drill pipe above the spacer fork to complete the docking or removal of the drill pipe, specifically as Figure 2 shown.

[0003] However, there are generally significant drawbacks in the current processes of lifting drill pipes, docking drill pipes, and removing drill pipes. First of all, in the process of lifting drill pipes, workers need to climb up and down the tower manually. The tower is about 4m high, and both the climbing up and down processes are high-altitude operations, which are very dangerous. Secondly, due to the factor of its own weight, the drill pipe in the core hole will cause the spacer fork to tilt at a certain angle during the process of connecting and removing drill pipes, and make the threaded connection part of the two drill pipes below the steel frame. It becomes very difficult to loosen or tighten the drill pipe with a special long-arm wrench. Summary of the Utility Model

[0004] In order to solve the problems existing in the above-mentioned prior art, a device for lifting, connecting and removing drill pipes of a drilling rig is provided, which does not require manual climbing of the tower during lifting, is convenient for removing drill pipes, and can improve the efficiency of drill pipe docking and drill pipe removal.

[0042] Embodiment 1

[0043] Please refer to Figure 3-8 The shown drill pipe hoisting, connection and unloading device, including a derrick 1, a collar 4, a lifting ring 5, a fork 8 and a steel frame 9; the lifting ring 5 is arranged on the derrick 1 and can move up and down relative to the derrick 1; the collar 4 is used to sleeved on the drill pipe 2 and can move along the axial direction of the drill pipe 2, and the collar 4 can be clamped with the upper end of the drill pipe 2; the lifting ring 5 is detachably connected with the collar 4; the steel frame 9 is located below the collar 4; the fork 8 is arranged on the steel frame 9 for fixing the drill pipe 2, and there are at least two supporting positions between the fork 8 and the steel frame 9.

[0044] Specifically, in this embodiment, the collar 4 includes a sleeve 401 and a hanging ear 402; a first through hole 403 for the drill pipe 2 to pass through is arranged in the sleeve 401; the hanging ear 402 is arranged outside the sleeve 401, and the collar 4 is hung on the lifting ring 5 through the hanging ear 402; the hanging ear 402 bends downward. There are 4 hanging ears 402, and the 4 hanging ears 402 are evenly arranged around the outside of the sleeve 401 to ensure that the drill pipe 2 is evenly stressed in the vertical direction during the hoisting process of the drill pipe 2, and to avoid bending of the drill pipe 2 due to unilateral stress on the drill pipe 2, which affects the service life of the drill pipe 2.

[0045] Specifically, the inner diameter of the sleeve 401 is smaller than the diameter of the end 3, so that the end 3 can clamp the sleeve 401, so that when the collar 4 moves to the top of the drill pipe 2, the sleeve 401 can be clamped with the end 3.

[0046] Specifically, it further includes a fixed pulley 14, a traction steel wire rope 7 and a power system; the fixed pulley 14 is arranged on the derrick 1; the traction steel wire rope 7 connects the fixed pulley 14 and the lifting ring 5; the lifting ring 5 includes a traction ring 501 corresponding to each hanging ear 402, and the hanging ear 402 can be hung on the traction ring 501 to realize the detachable connection between the lifting ring 5 and the collar 4, and the fixed pulley 14 is connected with the power system, and the power system can drive the fixed pulley 14 to rotate.

[0047] Specifically, the fork 8 includes a U-shaped socket and a handle arranged at the rear end of the U-shaped socket, and the U-shaped socket can clamp the drill pipe 2. In this embodiment, the handle is connected to the longitudinal rod of the steel frame 9, and the U-shaped socket end of the fork 8 extends to be connected to the other longitudinal rod of the steel frame 9, so that both ends of the fork 8 are connected to the steel frame 9 to form two supporting positions.

[0048] The working principle of this embodiment is as follows:

[0049] When the drill rig is hoisting the drill pipe, the fixed pulley 14 is rotated through the power system, so that the lifting ring 5 moves downward to the bottom of the drill rig. The drill rig operator stands on the ground or the workbench and hangs the hanging ear 402 on the towing ring 501. The power system controls the rotation of the fixed pulley 14, so that the lifting ring 5 drives the collar 4 to move axially upward along the drill pipe 2. When the collar 4 moves to the top of the drill pipe 2, the end 3 is clamped with the collar 4, so that the collar 4 drives the drill pipe 2 to move upward together, completing the hoisting of the drill pipe. When the drill rig needs to connect or disassemble the drill pipe, the drill pipe 2 in the core hole is clamped and fixed with the pad fork 8. Since both ends of the pad fork 8 are connected to the steel frame 9, the drill pipe 2 in the core hole can be prevented from moving downward under its own weight, driving the pad fork 8 to tilt, and at the same time making the butt joint part of the drill pipe 2 move below the steel frame 9, resulting in inconvenient connection or disassembly operations of the drill pipe.

[0050] Embodiment 2

[0051] Please further refer to Figure 9 , the difference between this embodiment and Embodiment 1 is that: the U-shaped socket is not extended; the steel frame 9 is provided with transverse steel bars and longitudinal steel bars horizontally arranged with the steel frame 9. There are two rows of transverse steel bars and longitudinal steel bars horizontally and parallelly arranged respectively. The transverse steel bars are secondary steel bars 11, and the longitudinal steel bars are main steel bars 10. The pad forks 8 are respectively connected to the steel frame 9 and the secondary steel bars 11, and two support positions are formed through the secondary steel bars 11.

[0052] Specifically, the diameter of the main steel bar 10 is larger than that of the secondary steel bar 11.

[0053] Preferably, in another specific embodiment, the U-shaped socket is extended until the open end is connected to another secondary steel bar 11, and three support positions are formed through the secondary steel bar 11, further ensuring the support performance of the pad fork 8.

[0054] Specifically, in this embodiment, when the drill rig needs to connect or disassemble the drill pipe, the drill pipe 2 in the core hole is clamped and fixed with the pad fork 8. Since the rear ends of the pad forks 8 are respectively connected to the steel frame 9 and the secondary steel bars 11, the two support positions shorten the length of the end (i.e., the U-shaped plug end) of the pad fork 8 fixing the drill pipe 2 suspended, and at the same time ensure the contact area between the U-shaped plug and the drill pipe 2. It can slow down the downward movement of the drill pipe 2 in the core hole under its own weight, reduce the tilt of the pad fork 8, and keep the butt joint part of the drill pipe 2 at the same position or above the steel frame 9. In addition, in this embodiment, it is not necessary to lengthen the pad fork 8 to make the pad fork 8 and the steel frame 9 have at least two support positions, avoiding the problem that the weight of the pad fork increases and it is not easy to operate due to lengthening the pad fork 8.

[0055] Embodiment 3

[0056] Please further refer toFigure 10 , the difference between this embodiment and Embodiment 1 is that the U-shaped socket is not extended; a transverse steel pipe and a longitudinal steel pipe are provided on the steel frame 9 and are horizontally arranged with respect to the steel frame 9. Two rows of the transverse steel pipes and the longitudinal steel pipes are respectively arranged horizontally and in parallel. The transverse steel pipe is the secondary steel pipe 13, and the longitudinal steel pipe is the main steel pipe 12. The cushion fork 8 is respectively connected to the steel frame 9 and the secondary steel pipe 13, and two support positions are formed through the secondary steel pipe 13.

[0057] Preferably, in another specific embodiment, the U-shaped socket is extended until the open end is connected to another secondary reinforcing bar 11, and three support positions are formed through the secondary reinforcing bar 11 to further ensure the supporting performance of the cushion fork 8.

[0058] Embodiment 4

[0059] Please further refer to Figure 11 , the difference between this embodiment and Embodiment 1 is that the U-shaped socket is not extended; a reaction plate 6 is provided on the steel frame 9, and the cushion fork 8 is arranged on the reaction plate 6; a second through hole 601 for the drill pipe 2 to pass through is provided on the reaction plate 6. When connecting or disconnecting the drill pipe, the U-shaped socket is correspondingly arranged with the second through hole 601 to clamp and fix the drill pipe 2 in the core drilling hole. The cushion fork 8 forms a plurality of support positions with the steel frame 9 through the reaction plate 6.

[0060] Specifically, a limiting member 603 is provided on the reaction plate 6, and the limiting member 603 is located on the side of the cushion fork 8. The limiting member 603 can limit the rotation of the cushion fork 8 when the drill pipe 2 is loosened or tightened, thereby preventing the cushion fork 8 from slipping.

[0061] Specifically, a drain hole 602 is provided on the reaction plate 6, and the drain hole 602 is used to prevent water from accumulating on the reaction plate 6 and avoid safety problems caused by water accumulation when loosening or tightening the drill pipe 2.

[0062] Specifically, the reaction plate 6 is a steel plate.

[0063] Specifically, in this embodiment, when the drilling rig needs to connect or disconnect the drill pipe, the cushion fork 8 is used to clamp and fix the drill pipe 2 in the core drilling hole. Since the rear end of the cushion fork 8 is connected to the reaction plate 6, the setting of the reaction plate 6 shortens the length from the end of the cushion fork 8 that fixes the drill pipe 2 (i.e., the U-shaped plug end) to the steel frame 9, and both ends of the cushion fork 8 are connected to the steel frame 9 through the reaction plate 6. The steel frame 9 can support both ends of the cushion fork 8, which can slow down the downward movement of the drill pipe 2 in the core drilling hole under its own weight, reduce the inclination of the cushion fork 8, and keep the butt joint part of the drill pipe 2 at the same position or above the steel frame 9. At the same time, in this embodiment, it is possible to achieve at least two support positions between the cushion fork 8 and the steel frame 9 without lengthening the cushion fork 8, avoiding the problem that the weight of the cushion fork increases and is not easy to operate due to lengthening the cushion fork 8. In addition, since the drill pipe that needs to be rotated for threaded connection with the drill pipe 2 in the core drilling hole is rotated when disconnecting or connecting the drill pipe, the limiting member 603 can prevent the drill pipe 2 from driving the cushion fork 8 to rotate, thereby preventing the cushion fork 8 from slipping.

[0064] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
