[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Chinese patent application 202311857310.0 filed on December 29, 2023, the contents of which are incorporated herein by reference. Technical Field

[0003] The present invention relates to the field of petroleum machinery, and in particular to a winding device for initially winding a steel wire rope of a winch, a winding machine for initially winding a steel wire rope of a winch, and a drilling rig. Background Art

[0004] When winding wire rope around the winch drum, an initial winding process is required. This process involves wrapping the drum with wire rope before use. This wire rope, typically unused, is then used as a safety rope, leaving at least one layer. Because the safety rope formed during the initial winding process is located at the bottom layer of the winch drum, it plays a crucial role in ensuring the overall effectiveness of the wire rope winding. If the bottom layer of safety rope is loosely wound, the upper layers of wire rope will become misaligned, causing rope pinching and tangling. As the load increases, wire rope wear accelerates, exacerbating pinching and tangling, posing serious safety risks to drilling.

[0005] Currently, the initial winding of the winch drum is mainly achieved by manual traction and hammer correction. There are no special tools or effective winding methods. This approach usually has the following disadvantages:

[0006] (1) The initial wire rope of the drum relies solely on limited manpower to pull the rope. When the initial section of the wire rope is loaded in a relaxed state, it is easy to force the relaxed wire rope toward the rope clamp side, posing a serious risk of tripping.

[0007] (2) The traction force provided by manpower is insufficient, which cannot ensure that the wire rope is completely attached to the drum. The broken line groove formed on the drum during the initial winding is not standardized, which seriously affects the outer winding;

[0008] (3) The manual winding process is very random, and the initial winding section often forms sporadic "high points", causing the outer layer of rope to "jump" and be arranged irregularly;

[0009] (4) In the process of hammering to correct the winding position of the wire rope, it is very easy to hit the tank body and scratch the wear-resistant layer of the two side plates of the drum. In addition, the wire rope will be damaged during the hammering process;

[0010] (5) The entire rope winding process is time-consuming and labor-intensive, with low work efficiency. Once the rope winding fails, the process of removing the wire rope becomes very difficult and cumbersome.

[0011] Therefore, based on the above problems, providing a high-quality and high-efficiency winding device for the initial winding of the winch wire rope has become a technical problem that needs to be solved urgently.

[0012] Summary of the Invention

[0013] The purpose of the present invention is to overcome the problems of poor winding quality and low working efficiency of the initial winding of the winch wire rope in the prior art, and to provide a winding device, method and drilling rig for the initial winding of the winch wire rope.

[0014] In order to achieve the above-mentioned objectives, the first aspect of the present invention provides a winding device for the initial winding of a wire rope on a winch, comprising: a retractable cava, wherein a channel is formed in the cava for accommodating the passage of the wire rope; a cava seat, wherein the cava seat is partially sleeved on the outside of the cava; a pressure plate, wherein the pressure plate and the cava seat together form an accommodating space, wherein the cava is installed in the accommodating space, and the pressure plate can apply radial pressure to the cava; and a traction device, wherein the traction device is connected to the cava seat and can provide traction to the cava seat away from the winch.

[0015] Through the above technical solution, a channel is formed in the cava, which can be used to accommodate the wire rope passing through. The cava seat is partially sleeved on the outside of the cava, and the pressure plate is used to cover the remaining part, so that the cava is enclosed by the pressure plate and the cava seat. At this time, radial pressure is applied to the cava through the pressure plate, so that the cava presses the wire rope. The pressure can be adjusted as needed, and at the same time, the wire rope is prevented from escaping from the cava during the winding process, causing a safety accident. In addition, a traction device is used to connect to the slip seat. Specifically, the traction device can be connected to the end of the slip seat away from the winch. The traction device can provide traction to the slip seat. The traction force is opposite to the tension applied to the wire rope during the winding process. That is, the traction device can provide traction to the slip seat away from the winch, so that the wire rope segment passing from the winding device to the drum of the winch can be kept in a taut state. That is, the traction device ensures that the wire rope segment passing from the winding device to the drum of the winch has sufficient tension. On the one hand, it ensures that the wire rope is fully engaged with the drum during the winding process to avoid local bulges; on the other hand, it can make the winding trajectory of the wire rope on the drum more controllable, thereby improving the winding quality of the wire rope. In addition, during the winding process of the wire rope, no hammering correction is required, which avoids the problem of hammering damaging the drum and wire rope. Moreover, during the entire winding process, no excessive human intervention is required, which improves the work efficiency of the winding operation.

[0024] Optionally, it further comprises a lifting ring provided on the slip seat, wherein the lifting ring is connected to the traction device.

[0025] Optionally, the traction equipment is a crane.

[0051] All terms used herein have the same meanings as understood by one of ordinary skill in the art to which the present invention belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0052] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0053] The present invention aims to solve the problems in the prior art of the winch drum in which the initial winding of the wire rope adopts the method of manual traction plus hammer correction, which has the main problems of the method that the wire rope is easily disengaged, causing safety accidents; the wire rope winding trajectory is irregular and the winding quality is poor; hammer correction is required, which is easy to damage the wire rope and the drum; and the rope winding operation requires a lot of manpower and working hours, resulting in low work efficiency. The present invention provides a winding device for the initial winding of the wire rope of the winch, with reference to Figures 1 to 5, the winding device includes: a retractable cava 2, a channel for accommodating the passage of the wire rope 7 formed in the cava 2; a cava seat 1, the cava seat 1 is partially sleeved on the outside of the cava 2; a pressure plate 3, the pressure plate 3 and the cava seat 1 together form an accommodating space, the cava 2 is installed in the accommodating space, and the pressure plate 3 can apply radial pressure to the cava 2; a traction device, the traction device is connected to the cava seat 1, and can provide traction to the cava seat 1 away from the winch 12.

[0054] Through the above technical solution, a channel is formed in the cava 2, which can be used to accommodate the wire rope 7 to pass through. The cava seat 1 is partially sleeved on the outside of the cava 2, and the pressure plate 3 is used to cover the remaining part, so that the cava 2 is enclosed by the pressure plate 3 and the cava seat 1. At this time, radial pressure is applied to the cava 2 through the pressure plate 3, so that the cava 2 presses the wire rope 7 to prevent the wire rope 7 from escaping from the cava 2 during the winding process, causing a safety accident. In addition, a traction device is used to connect to the slip seat 1. Specifically, the traction device can be connected to the end of the slip seat 1 away from the winch 12. The traction device can provide traction to the slip seat 1. The traction force is opposite to the tension applied to the wire rope 7 during the winding process. That is, the traction device can provide traction to the slip seat 1 away from the winch 12, so that the wire rope segment passing from the winding device to the drum of the winch 12 can be kept taut. That is, the traction device ensures that the wire rope segment passing from the winding device to the drum of the winch 12 has sufficient tension. On the one hand, it ensures that the wire rope 7 is fully engaged with the drum during the winding process to avoid local bulges; on the other hand, it can make the winding trajectory of the wire rope 7 on the drum more controllable, thereby improving the winding quality of the wire rope 7. In addition, during the winding process of the wire rope 7, no hammering correction is required, thereby avoiding the problem of hammering damaging the drum and the wire rope 7. Moreover, during the entire winding process, no excessive human intervention is required, thereby improving the working efficiency of the winding operation.

[0055] 1 and 4 , the slip seat includes a back plate, a first side plate and a second side plate respectively perpendicular to the back plate, the first side plate and the second side plate being arranged opposite each other, and the slip seat 1 is surrounded by the back plate, the first side plate and the second side plate to form a rectangular parallelepiped with an opening, with both ends of the rectangular parallelepiped being open. The slip seat 1 is partially sleeved on the outside of the slip 2 through the above-mentioned opening, and the pressing plate 3 is a flat plate with a raised middle portion. The pressing plate 3 cooperates with the above-mentioned opening through the raised portion, so that the pressing plate 3 and the slip seat 1 can enclose a storage space, and the slip 2 is installed in the storage space. By applying radial pressure to the pressing plate 3, the raised portion squeezes the slip 2, causing the slip 2 to be subjected to the same radial pressure, thereby tightening the wire rope 7 inside the slip 2.

[0056] In some embodiments of the present invention, threaded holes can be provided on the pressure plate 3, and side plate threaded holes can be provided on the end surfaces of the first and second side plates of the slip seat 1 at positions relative to the threaded holes, so that bolts can pass through the threaded holes on the pressure plate 3 and extend into the side plate threaded holes of the slip seat 1. At this time, by adjusting the torque of the bolts, the depth of the bolts extending into the side plate threaded holes of the slip seat 1 can be adjusted, thereby adjusting the radial pressure exerted by the bolts on the pressure plate 3, and further adjusting the radial pressure exerted by the slips on the wire rope 7. When the radial pressure exerted on the wire rope 7 meets the construction requirements, the wire rope 7 can be wound around the drum of the winch 12.

[0057] Alternatively, optionally, the winding device for initially winding a wire rope for a winch provided by the present invention further comprises a sleeve 4 at least partially surrounding the slip seat 1 and the pressure plate 3 , and radial pressure can be applied to the pressure plate 3 through the sleeve 4 .

[0058] Specifically, the ferrule 4 can completely surround the slip seat 1 and the pressing plate 3. Alternatively, referring to Figures 1 and 4, the ferrule 4 partially surrounds the slip seat 1 and the pressing plate 3, wherein the ferrule 4 completely surrounds the pressing plate 3, the first side plate and the second side plate, and partially surrounds the back plate, and forms a fracture on the back plate, thereby facilitating the installation of the slip seat 1, the pressing plate and the pressure detector 8 described below. In addition, the manufacturing materials of the ferrule 4 can be saved, reducing the production input cost.

[0059] Optionally, referring to Figures 1 to 4, a tightening bolt 5 is further included, which is threadedly connected to the threaded hole on the side of the ferrule 4 close to the pressure plate 3. The tightening bolt 5 passes through the threaded hole on the ferrule 4 and is connected to the pressure plate 3. By tightening the tightening bolt 5, radial pressure can be applied to the pressure plate 3, thereby applying radial pressure to the slips 2, increasing the friction between the slips 2 and the wire rope 7, and preventing the wire rope 7 from detaching from the slips 2 during the winding process, causing a safety accident. Furthermore, the number of tightening bolts 5 and threaded holes can be multiple. Optionally, after multiple tightening bolts 5 pass through corresponding threaded holes, they are evenly distributed on the pressure plate 3, so that the pressure plate 3 can evenly apply radial pressure to the slips 2 to compress the wire rope 7, ensuring that the wire rope 7 is subjected to sufficient friction during the winding process.

[0060] Alternatively, in some embodiments of the present invention, the portion of the ferrule 4 located on the back plate of the slip seat 1 has two protruding rings extending radially outward, each of which has a protruding ring threaded hole. The two protruding ring threaded holes are symmetrically arranged with respect to the axial extension direction of the slip. By inserting a bolt through the protruding ring threaded hole and tightening the bolt, the distance between the two protruding rings can be reduced, that is, the distance between the fractures of the ferrule 4 can be reduced, thereby achieving the purpose of applying radial pressure to the pressure plate 3 through the ferrule 4, thereby compressing the wire rope 7.

[0061] Optionally, referring to Figures 3 and 4, the winding device for the initial winding of the winch provided by the present invention also includes a wear-resistant sleeve 6 provided on the inner surface of the slip 2, and a channel for accommodating the passage of the wire rope 7 is formed in the slip 2. The channel is cylindrical, and the wear-resistant sleeve 6 is cylindrical. The outer diameter of the wear-resistant sleeve 6 is the same as the diameter of the above-mentioned channel, and the inner diameter of the wear-resistant sleeve 6 is the same as the diameter of the wire rope 7. After the wire rope 7 passes through the wear-resistant sleeve, one end is fixed on the drum of the winch 12, and the wear-resistant sleeve 6 is installed in the channel of the slip 2. The wear-resistant sleeve 6 can prevent the wire rope 7 from being worn by the slip 2 during the winding process, causing the wire rope 7 to break.

[0062] Optionally, referring to FIG6 , the inner wall of the wear-resistant sleeve 6 is provided with a pattern 601 that matches the outer circumference of the steel wire rope 7. Specifically, the steel wire rope 7 is typically composed of steel wires and a rope core. The pattern is formed by twisting multiple layers of steel wires into strands, and then spirally winding a certain number of strands around the rope core. Therefore, the outer circumference of the steel wire rope 7 has an uneven pattern. The inner wall of the wear-resistant sleeve 6 is provided with a pattern 601 that matches the outer circumference of the steel wire rope 7. This increases the contact area between the inner wall of the wear-resistant sleeve 6 and the steel wire rope 7, which helps further enhance the friction between the wear-resistant sleeve 6 and the steel wire rope 7. When the steel wire rope 7 is subjected to a load, the wear-resistant sleeve 6 also functions to convert the friction between the steel wire rope 7 and the wear-resistant sleeve 6 into friction between the slips 2 and the wear-resistant sleeve 6.

[0063] Optionally, referring to Figure 1, the winding device for initially winding the winch wire rope provided by the present invention also includes a pressure detector 8 for measuring the radial pressure exerted on the pressure plate 3. The radial pressure exerted on the pressure plate 3 can be measured by the pressure detector 8, thereby obtaining the radial pressure exerted on the cava 2 by the pressure plate 3, and then obtaining the magnitude of the friction force exerted on the wire rope 7.

[0064] In some embodiments of the present invention, the sensing element of the pressure detector 8 is arranged between the ferrule 4 and the pressure plate 3, so as to measure the pressure between the ferrule 4 and the pressure plate 3, and then obtain the friction force exerted on the wire rope 7.

[0065] Alternatively, with reference to Figures 3 and 4, the sensing element of the pressure detector 8 is disposed between the back plate of the slip seat 1 and the ferrule 4. The pressure between the back plate of the slip seat 1 and the ferrule 4 can be measured to obtain a pressure equal to the radial pressure exerted by the tightening bolt 5 on the pressure plate 3, the radial pressure exerted by the pressure plate 3 on the slip 2, and the pressure between the wire rope 7 and the wear-resistant sleeve 6. The friction force between the wire rope 7 and the wear-resistant sleeve 6 can be calculated based on the pressure between the wire rope 7 and the wear-resistant sleeve 6.

[0066] Alternatively, the slips 2 may be split-flap slips, such as three-flap slips or four-flap slips. Alternatively, referring to FIG4 , the slips 2 may be two-flap slips, where the abutting surface of the two-flap slips is parallel to the pressure plate 3, facilitating radial pressure exerted by the pressure plate 3 on the slips 2. Corresponding to the slips 2, the wear-resistant sleeve 6 may also be split-flap slips. For example, when the slips 2 are two-flap slips, the wear-resistant sleeve 6 is also two-flap slips.

[0067] Optionally, with reference to Figures 1, 2, and 3, the winding device for initially winding a wire rope on a winch provided by the present invention further includes a lifting ring 9 provided on the slip seat 1, and the lifting ring 9 is connected to a traction device. Specifically, the lifting ring 9 is provided at an end of the slip seat 1 away from the winch 12, so that a traction force away from the winch 12 is provided to the slip seat 1 through the traction device, thereby ensuring that the winding work of the wire rope 7 on the drum of the winch 12 is carried out normally.

[0068] Optionally, referring to FIG5 , the traction device is a crane 11, and the boom 1101 of the crane 11 passes through the connection hole on the lifting ring 9 through the connecting rope, thereby being connected to the lifting ring 9. Then, during the winding process of the wire rope 7, the crane 11 can provide traction force to the slip seat 1 away from the winch 12, so that the wire rope segment between the winding device 10 and the winch 12 can be formed into a taut wire rope 701 during the winding process, while the wire rope 7 that has not passed through the winding device 10 is formed into a slack wire rope 702. The crane 11 provides traction force to the slip seat 1 away from the winch 12, so that the taut wire rope 701 has sufficient tension, ensuring that the wire rope 7 can fully fit the drum during the winding process, avoiding the problem of local bulges, and at the same time making the winding trajectory of the wire rope 7 more controllable, thereby improving the winding quality.

[0069] Of course, the slip seat 1 can also be connected to the derrick through the lifting ring 9, so that during the winding process of the wire rope 7, the derrick can provide the slip seat 1 with traction away from the winch 12.
