Description

Technical Field

[0001] This utility model relates to the field of oil drilling equipment technology, and in particular to a drilling fast rope guide wheel alignment device. Background Technology

[0002] The drilling fast rope guide sheave is installed on the guide sheave beam at the top of the derrick's A-frame, providing tension and support for the fast rope of the drilling main rope. Because the guide sheave can only rotate around the guide sheave beam and cannot move axially, its position is fixed. The fast rope, however, only moves left and right along the winch drum, which may cause it to misalign with the guide sheave and fail to enter the guide sheave groove. During derrick hoisting and lowering operations, workers need to climb to a height of 2-9 meters above the ground to manually align the guide sheave. During this manual adjustment, workers face a risk of falling from height. Especially during derrick lowering operations, when the derrick tilts to approximately 75 degrees, the guide sheave may not automatically align with the fast rope, preventing it from entering the guide sheave. At this point, derrick lowering must be stopped. The main rope bears the maximum load at this point, making it highly susceptible to the fast rope becoming loose or damaged, potentially leading to a derrick collapse.

[0003] In summary, developing a centering device that can align the drilling rig with the guide sheave groove is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a drilling fast rope guide wheel alignment device; please refer to the appendix of the instruction manual. Figures 1 to 4 It should be noted that the guide rope wheel 13 is held by two support plates on the side wall of the crossbeam 12. The guide rope wheel 13 can swing between the support plates along its rotation axis. The rotation axis of the guide rope wheel 13 is parallel to the crossbeam 12. The fast rope is connected to the groove of the guide rope wheel 13, providing a stable and sufficient tension fulcrum for the drilling fast rope. This utility model includes two first pressure plates 1 on the crossbeam 12, each first pressure plate 1 arranged along the axial direction of the crossbeam. A horizontal drive cylinder 2 is fixed between the first pressure plates 1. A moving rod 4 is slidably provided in the inner cavity of the horizontal drive cylinder 2. The feed direction of the horizontal drive cylinder 2 is parallel to the axis of the crossbeam. A centering cylinder 3 is fixedly connected to the side wall of the moving rod 4. A centering rod 5 is also slidably provided in the inner cavity of the centering cylinder 3. The feed direction of the centering rod 5 is perpendicular to the rotation axis of the guide rope wheel 13. The horizontal drive cylinder 13 and the horizontal drive cylinder 2 are distributed on different generatrices on the side wall of the crossbeam 12. Therefore, the centering rod 5 fixed on the moving rod 4 is inclined to the side closer to the rotation axis of the guide rope wheel 13, so that the end of the centering rod 5 corresponds to the side wall of the guide rope wheel 13, so that the centering rod 4 can engage with the guide rope wheel 13 and drive the guide rope wheel 13 to move, so that the groove of the guide rope wheel connects with the fast rope. The horizontal drive cylinder 2 and the centering cylinder 3 are both connected to the hydraulic control system. The hydraulic control system is used to control the operation of the horizontal drive cylinder 2 and the centering cylinder 3.

[0028] During the derrick release process, the derrick gradually tilts. When the derrick tilts to a certain degree, the fast rope needs to be placed into the groove of the guide rope pulley 13. Because the fast rope swings back and forth along the axis of the crossbeam 12, it often cannot automatically align with the groove of the guide rope pulley 13. The operator supplies hydraulic oil to the horizontal drive cylinder 2 through the hydraulic control system, causing the moving rod 4 to extend along the axis of the crossbeam, aligning the centering rod 5 on the side wall of the moving rod 4 with the guide rope pulley 13. Then, the hydraulic control... The system supplies hydraulic oil to the alignment cylinder 3, which pushes the alignment rod 5, causing it to engage with the guide rope wheel 13. This allows the guide rope wheel 13 to move together with the alignment rod 5. The system then drives the horizontal drive cylinder 2 again, causing the alignment rod 5 to move the guide rope wheel 13 closer to the fast rope, aligning the groove of the guide rope wheel 13 with the fast rope. After the horizontal drive cylinder 2 and the alignment cylinder 3 are reset, the derrick continues to be lowered. At this point, the fast rope is slowly engaged into the groove of the guide rope wheel 13, completing the alignment operation.

[0029] Preferably, a second pressure plate 11 is also connected to the side wall of the crossbeam 12. The two first pressure plates 1 and the second pressure plate 11 are arranged sequentially along the feed direction of the horizontal drive cylinder 2. Each first pressure plate 1 and the second pressure plate 11 is connected to the crossbeam 12 by a fixing clamp 6. The fixing clamp 6 includes two mutually symmetrical clamps. Each clamp is specifically a C-shaped arc plate. Connecting plates extend from the two sides of each clamp, clamping each clamp to both sides of the crossbeam 12. At this time, the connecting plates of the mutually symmetrical clamps fit together, and a connector is inserted between the fitted connecting plates. This ensures that each clamping clamp is engaged with the crossbeam 12, thereby locking the positions of the first pressure plate 1 and the second pressure plate 11. Furthermore, each first pressure plate 1 has a fastening hole, the axis of which is parallel to the axis of the crossbeam 12. The horizontal drive cylinder 2 is interference-fitted into the fastening hole to ensure the relative position of the horizontal drive cylinder 2 on the crossbeam 12 is stable. In addition, a rib 41 is connected to the end of the moving rod 4 away from the first pressure plate 1. A snap-fit ​​hole is provided inside the second pressure plate 11. The snap-fit ​​hole is a rib hole, and the rib 41 passes through the locking hole with a clearance fit. In one embodiment of this application, the horizontal drive cylinder 2 aligns the alignment rod 5 with the groove of the guide rope wheel 13, and the alignment cylinder 3 extends the alignment rod 5 to engage with the guide rope wheel 13. Due to the gravity of the alignment rod 5 itself, the alignment rod 5 tends to rotate around the axis of the moving rod 4. At this time, the side wall of the rib 41 passing through the second pressure plate 11 abuts against the inner wall of the locking hole, restricting the rotation of the moving rod 4, keeping the tilt angle of the alignment rod 5 stable, and ensuring that the end of the alignment rod 5 always aligns with the guide rope wheel 13.

[0030] Please refer to the instruction manual appendix. Figure 3 and 4The centering lever 5 includes a straight sliding part. A fork 51 is connected to the end of the sliding part away from the centering cylinder 3. The fork 51 is U-shaped. The width of the fork 51 port is slightly greater than the thickness of the guide rope wheel 13, so that the fork 51 can easily hold the guide rope wheel 13 inside itself. Similarly, the fast rope held inside the fork 51 is connected to the groove of the guide rope wheel 13. Specifically, the U-shaped fork 51 is cut and welded from a steel plate. The length of the fork 51 is less than the radius of the guide rope wheel 13 and greater than half the radius of the guide rope wheel 13. The length of the fork 51 is adjusted to avoid the side plate of the fork 51 abutting against the end face of the guide rope wheel 13 during the movement of the centering lever 5 driven by the moving lever 4 due to the excessive length of the fork 51, which would prevent the fast rope from connecting with the groove of the guide rope wheel 13.

[0031] Furthermore, the alignment cylinder 3 is connected to the moving rod 4 via the support plate 7. Two through holes are provided at both ends of the support plate 7 along its length, and these two through holes are arranged along the width of the support plate 7. A mating groove is provided along the length of the support plate 7. The alignment cylinder 3 fits into the mating groove, positioning it between the two through holes. Locking buckles, specifically U-shaped buckles, are inserted inside the two through holes. The locking buckles hold the alignment cylinder 3 within themselves, with the curved portion of the locking buckle fitting against the side wall of the alignment cylinder 3. Each locking buckle has a threaded section at its end where it passes through the through hole, and fasteners are screwed onto these threaded sections. After the fasteners abut against the side wall of the support plate 7, the fasteners are further tightened, causing the support plate 7 and the locking buckles to clamp the alignment cylinder 3, thus locking the position of the alignment cylinder 3.

[0032] Preferably, the hydraulic control system includes a control box 9 and a hydraulic source 8. The control box 9 is connected to the hydraulic source 8 via a hydraulic pipe 10. Several interfaces are provided on the control box 9, each connected to the hydraulic source 8. The control box 9 also includes a first control valve 91 and a second control valve 92, which are used to regulate the connection and disconnection of the hydraulic source 8 at each interface. The interface connected to the first control valve 91 is connected to the horizontal drive cylinder 2 via the hydraulic pipe 10, and the interface connected to the second control valve 92 is connected to the centering cylinder 3 via the hydraulic pipe 10. Preferably, both ends of the horizontal drive cylinder 2 and the centering cylinder 3 are connected to hydraulic pipes 10, allowing hydraulic pipes to flow to the horizontal drive cylinder. Hydraulic oil is supplied to the different ends of the horizontal drive cylinder 2 and the horizontal drive cylinder 3 to achieve the extension and retraction of the horizontal drive cylinder 2 and the horizontal drive cylinder 3. Preferably, both ends of each hydraulic pipe 10 are connected to a non-overflow quick-connect coupling, which makes the connection process of the hydraulic pipe 10 simpler and prevents the hydraulic oil from overflowing from the port of each hydraulic pipe 10. In actual use, there are 5 to 8 hydraulic pipes 10. The operator turns the first control valve 91 to supply hydraulic oil to the horizontal drive rod to extend the moving rod 4. The horizontal drive cylinder 3 connected to the moving rod 4 corresponds to the guide rope wheel 13. Turning the second control valve 92 causes the horizontal drive cylinder 3 to drive the horizontal drive rod 5 to extend. The shift fork 51 of the horizontal drive rod 5 is connected to the guide rope wheel 13.

[0033] Specifically, both the horizontal drive cylinder 2 and the centering cylinder 3 are bidirectional telescopic cylinder assemblies. The effective telescopic length of the horizontal drive cylinder 2 is 1.5m to 1.8m, and the load capacity is 500kg to 1000kg. The effective telescopic length of the centering cylinder 3 is 0.2m to 0.4m, and the load capacity is 50kg to 100kg. The hydraulic pipe 10 is a high-pressure prefabricated hose with a pressure resistance of not less than 10 MPa.

[0034] In one embodiment of this utility model, the guide rope wheel alignment device is installed on the crossbeam 12 at the top of the derrick's A-frame. The operator uses the guide rope wheel 13 on the crossbeam 12 to raise and lower the derrick. During the gradual release of the fast rope, the reciprocating fast rope cannot accurately align with the groove of the guide rope wheel 13. The operator activates the hydraulic source 8 and operates the first control valve 91. The hydraulic source 8 supplies hydraulic oil to the horizontal drive cylinder 2, which in turn extends the moving rod 4, aligning the fork 51 of the alignment rod 5 with the groove of the guide rope wheel 13. After retracting the first control valve 91, the operator operates the second control valve 92. Hydraulic source 8 delivers hydraulic oil to the alignment cylinder 3. The alignment cylinder 3 drives the alignment rod 5 to extend a certain length, engaging the fork 51 with the guide rope wheel 13. Then, the second control valve 92 is turned back and the first control valve 91 is turned back again. The moving rod 4 continues to extend, moving together with the guide rope wheel 13 engaged with the alignment rod 5. When the groove of the guide rope wheel 13 aligns with the fast rope, the horizontal drive cylinder 2 and the alignment cylinder 3 are reset, and the derrick continues to be slowly lowered, so that the fast rope aligns with the groove of the guide rope wheel 13. The guide rope wheel 13 can move left and right with the fast rope. At this time, the guide rope wheel 13 becomes the rotating fixed pulley of the fast rope, providing a reliable support point for the fast rope.

[0035] In summary, the fast rope guide wheel alignment device provided in this application allows operators to operate the hydraulic control mechanism from a safe position such as the ground or drilling platform to quickly align the guide wheel 13, eliminating the need for operators to climb to a height for manual alignment and eliminating the safety risk of falls from heights. At the same time, by using the horizontal drive cylinder 2 and the alignment cylinder 3 as actuators, the device enables mechanical alignment of the guide wheel 13 and continuous lowering of the derrick, reducing labor intensity while improving work efficiency.

[0037] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
