Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly relates to a winding device for winding steel wire ropes on a winch and a method for initially winding steel wire ropes using this device. On this basis, the present invention also relates to a drilling rig. Background Art

[0002] When the drum of a winch winds a steel wire rope, initial rope winding is required first. Initial rope winding refers to: the steel wire rope that needs to be wound on the drum of the winch before use. This steel wire rope generally does not participate in work and leaves more than one layer as a safety rope. Since the safety rope of the initial winding is located at the bottom layer of the drum of the winch, it plays a crucial role in the overall effect of the steel wire rope winding. If the safety rope at the bottom layer is wound loosely, it will cause the upper-layer steel wire ropes to be arranged unevenly, resulting in phenomena such as rope jamming and tangling. Along with the increase in load, the wear of the steel wire rope accelerates, and the rope jamming and tangling intensify, bringing serious safety risks to drilling.

[0003] Currently, the initial rope winding of the drum of a winch is mainly achieved by manual traction plus hammering correction. There is no special tool and effective winding method. This method usually has the following disadvantages: (1) The initial steel wire rope of the drum is only wound by limited manual traction. After the initial section of the steel wire rope under a slack state is loaded, it is easy to force the slack steel wire rope backward toward the side of the rope clamp, posing a very significant risk of unclamping. (2) The traction force provided by manpower is insufficient, so it cannot ensure that the steel wire rope is completely adhered to the drum. The broken-line rope groove trajectory formed by the initial rope winding on the drum is not standard, seriously affecting the outer-layer rope winding. (3) The process of manual rope winding is highly random. The initial rope winding section often forms sporadic "high points", resulting in "rope skipping" of the outer-layer rope winding and irregular arrangement. (4) During the process of hammering and correcting the winding position of the steel wire rope, it is extremely easy to hit the groove body and scratch the wear-resistant layer on both sides of the drum. In addition, the steel wire rope will be damaged during the hammering process. (5) The entire rope winding work is time-consuming and laborious, with low work efficiency. Once the rope winding fails, the process of removing the steel wire rope is very difficult and cumbersome.

[0004] Therefore, due to the above various problems, providing a high-quality and high-efficiency winding device for initially winding steel wire ropes on a winch has become an urgent technical problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems of poor winding quality and low work efficiency in the initial winding of steel wire ropes on a winch in the prior art, and to provide a winding device, a method, and a drilling rig for initially winding steel wire ropes on a winch.

[0006] In order to achieve the above-mentioned objectives, the first aspect of the present invention provides a winding device for initially winding a wire rope for a winch, comprising: a retractable cava, in which a channel is formed 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 a 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.

[0007] Through the above technical solution, a channel is formed inside the cava, and the channel can be used to accommodate the wire rope passing through. The cava seat is partially sleeved on the outside of the cava, and the remaining part is covered by the pressure plate, 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 to prevent the wire rope from escaping from the cava during the winding process and causing a safety accident. In addition, a traction device is used to connect 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 is opposite to the pulling force 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 makes the wire rope segment passing from the winding device to the drum of the winch have sufficient tension. On the one hand, it ensures that the wire rope is completely 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, there is no need for hammer correction, which avoids the problem of hammer damage to the drum and the wire rope. Moreover, during the entire winding process, there is no need for excessive human intervention, which improves the work efficiency of the winding operation.

It should also be understood that terms defined in, for example, a general dictionary 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 overly formal sense, unless specifically defined as such herein.

[0029] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0030] In view of the problems in the prior art that the initial wire rope winding of a winch drum adopts the method of manual traction plus hammering correction, which mainly has the problems that the wire rope is prone to tripping, causing safety accidents; the wire rope winding trajectory is irregular and the winding quality is poor; hammering correction is required, which is easy to damage the wire rope and the drum; and a large amount of manpower and working hours are required for the wire rope winding operation, and the work efficiency is low, the present invention provides a winding device for initially winding the wire rope of a winch. Referring to Figures 1 to 5 , the winding device includes: a retractable jaw 2, a channel for accommodating the wire rope 7 to pass through is formed in the jaw 2; a jaw seat 1, the jaw seat 1 is partially sleeved outside the jaw 2; a pressing plate 3, the pressing plate 3 and the jaw seat 1 enclose a receiving space, the jaw 2 is installed in the receiving space, and the pressing plate 3 can apply a radial pressure to the jaw 2; a traction device, the traction device is connected to the jaw seat 1 and can provide a traction force away from the winch 12 to the jaw seat 1.

[0031] Through the above technical solution, a channel is formed in the slip 2, and the channel can be used to accommodate the wire rope 7 to pass through. The slip seat 1 is partially sleeved outside the slip 2, and then the remaining part is covered by the pressing plate 3, so that the slip 2 is surrounded by the pressing plate 3 and the slip seat 1. At this time, a radial pressure is applied to the slip 2 through the pressing plate 3, so that the slip 2 presses the wire rope 7 tightly, preventing the wire rope 7 from detaching from the slip 2 during the winding process and causing a safety accident. In addition, a traction device is connected 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 a traction force to the slip seat 1, and the direction of this traction force is opposite to the direction of the tension force received by the wire rope 7 during the winding process. That is, the traction device can provide a traction force away from the winch 12 to the slip seat 1, so that the wire rope segment passing from the winding device to the drum of the winch 12 can be kept in a tensioned state. That is, the traction device makes the wire rope segment passing from the winding device to the drum of the winch 12 have sufficient tension. On the one hand, it ensures that the wire rope 7 is fully engaged with the drum during the winding process, avoiding the situation of local protrusions; 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, there is no need for hammering correction, avoiding the problems of hammering damage to the drum and the wire rope 7. Moreover, during the entire winding process, there is no need for excessive human intervention, improving the working efficiency of the winding operation.

[0032] Referring to Figure 1 and Figure 4 , the slip seat includes a back plate, a first side plate and a second side plate that are respectively perpendicular to the back plate. The first side plate and the second side plate are arranged opposite to each other. The slip seat 1 surrounds and forms a cuboid with an opening through the back plate, the first side plate and the second side plate. Both ends of the cuboid are open ends. The slip seat 1 is partially sleeved outside the slip 2 through the above opening. The pressing plate 3 is in the shape of a flat plate with a convex middle part. The pressing plate 3 is matched with the above opening through the convex part, so that the pressing plate 3 and the slip seat 1 can surround and form an accommodating space, and the slip 2 is installed in this accommodating space. By applying a radial pressure to the pressing plate 3, the convex part squeezes the slip 2, so that the slip 2 receives the same radial pressure, and then presses the wire rope 7 inside the slip 2 tightly.

[0033] In some embodiments of the present invention, a threaded hole can be provided in the pressing plate 3, and side plate threaded holes can be provided at the relative positions of the end faces of the first side plate and the second side plate of the slip seat 1 corresponding to the above threaded hole, so that the bolt can pass through the threaded hole in the pressing plate 3 and extend into the side plate threaded hole of the slip seat 1. At this time, by adjusting the torque of the bolt, the depth of the bolt extending into the side plate threaded hole of the slip seat 1 can be adjusted, so as to adjust the radial pressure applied to the pressing plate 3 by the bolt, and further adjust the radial pressure received by the wire rope 7 from the slip. When the radial pressure received by the wire rope 7 meets the construction requirements, the wire rope 7 can be wound on the drum of the winch 12.

[0034] Alternatively, preferably, the winding device for initially winding the wire rope of the winch provided by the present invention further includes a bushing 4 that at least partially surrounds the slip seat 1 and the pressure plate 3, and a radial pressure can be applied to the pressure plate 3 through the bushing 4.

[0035] Specifically, the bushing 4 can completely surround the slip seat 1 and the pressure plate 3. Alternatively, referring to Figure 1 and Figure 4 , the bushing 4 partially surrounds the slip seat 1 and the pressure plate 3, wherein the bushing 4 completely surrounds the pressure plate 3, the first side plate and the second side plate, partially surrounds the back plate, and forms a break on the back plate, so as to facilitate the installation of the slip seat 1, the pressure plate and the following pressure detector 8. In addition, the production material of the bushing 4 can be saved, and the production input cost can be reduced.

[0036] Preferably, referring to Figures 1 to 4 , it further includes a tightening bolt 5, and the tightening bolt 5 is threadedly connected to a threaded hole on the side of the bushing 4 close to the pressure plate 3. The tightening bolt 5 passes through the threaded hole on the bushing 4 and abuts against the pressure plate 3. By tightening the tightening bolt 5, a radial pressure can be applied to the pressure plate 3, so as to apply a radial pressure to the slip 2, increase the friction between the slip 2 and the wire rope 7, and prevent the wire rope 7 from disengaging from the slip 2 during the winding process and causing a safety accident. Further, the number of the tightening bolts 5 and the threaded holes can be multiple. Preferably, after the multiple tightening bolts 5 pass through the corresponding threaded holes respectively, they are evenly distributed on the pressure plate 3, so that the pressure plate 3 can evenly apply a radial pressure to the slip 2 to press the wire rope 7 and ensure that the wire rope 7 receives sufficient friction during the winding process.

[0037] Alternatively, in some embodiments of the present invention, the part of the bushing 4 located on the back plate of the slip seat 1 has two convex rings arranged along the radially outward extending direction, and convex ring threaded holes are provided on the two convex rings. The two convex ring threaded holes are symmetrically arranged with respect to the extending direction of the slip axial line. By passing a bolt through the convex ring threaded hole and tightening the bolt, the distance between the two convex rings can be reduced, that is, the distance of the break of the bushing 4 can be reduced, so as to achieve the purpose of applying a radial pressure to the pressure plate 3 through the bushing 4 and further pressing the wire rope 7.

[0038] Preferably, referring to Figure 3 and Figure 4 , the winding device for initially winding the wire rope of the winch provided by the present invention further includes a wear-resistant sleeve 6 provided on the inner surface of the slip 2. A channel for accommodating the wire 7 to pass through is formed in the slip 2. The channel is cylindrical, 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, 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 to the drum of the winch 12. The wear-resistant sleeve 6 is installed in the channel of the slip 2. Through the wear-resistant sleeve 6, it can be prevented that the wire rope 7 is worn by the slip 2 during the winding process, resulting in the breakage of the wire rope 7.

[0039] Preferably, the inner wall of the wear-resistant sleeve 6 is provided with a texture that matches the concave-convex texture of the outer peripheral surface of the steel wire rope 7. Specifically, the steel wire rope 7 is usually composed of steel wires and a rope core, and is made by twisting multiple layers of steel wires into strands, and then spirally winding a certain number of strands twisted by steel wires around the rope core, so that the outer peripheral surface of the steel wire rope 7 has an uneven texture. The wall surface of the inner wall of the wear-resistant sleeve 6 is provided with a texture that matches the concave-convex texture of the outer peripheral surface of the steel wire rope 7, which increases the contact area between the inner wall of the wear-resistant sleeve 6 and the steel wire rope 7, which is conducive to further enhancing the friction between the wear-resistant sleeve 6 and the steel wire rope 7.

[0040] Preferably, refer to Figure 1 The winding device for initially winding a steel wire rope for a winch 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 further obtaining the magnitude of the friction force exerted on the steel wire rope 7.

[0041] In some embodiments of the present invention, the sensing element of the pressure detector 8 is disposed 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 on the wire rope 7 .

[0042] Or, preferably, refer to Figure 3 and Figure 4 The sensing element of the pressure detector 8 is arranged 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 obtained by measuring. The pressure is equal to the radial pressure exerted by the tightening bolt 5 on the pressure plate 3, and also equal to the radial pressure exerted by the pressure plate 3 on the slip 2, and also equal to the pressure between the wire rope 7 and the wear-resistant sleeve 6. The friction between the wire rope 7 and the wear-resistant sleeve 6 can be calculated by the pressure between the wire rope 7 and the wear-resistant sleeve 6.

[0043] In addition, the slip 2 may be a split slip, such as a three-petal slip, or a four-petal slip. Figure 4 The slip 2 is a two-petal slip, and the butt joint surface of the two-petal slip is parallel to the pressure plate 3, so that the pressure plate 3 can apply radial pressure to the slip 2.

[0044] Preferably, refer to Figure 1 , Figure 2 and Figure 3 The winding device for initially winding the steel wire rope of the 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 the traction device. Specifically, the lifting ring 9 is provided at one end of the slip seat 1 away from the winch 12, so that the traction force away from the winch 12 is provided to the slip seat 1 through the traction device, so as to ensure that the winding work of the steel wire rope 7 on the drum of the winch 12 is carried out normally.

[0045] Preferably, refer to Figure 5 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 connection rope, so as to be connected to the lifting ring 9. Then, during the winding process of the wire rope 7, the crane 11 can provide the slip seat 1 with a traction force 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, and the wire rope 7 that has not penetrated the winding device 10 is formed into a slack wire rope 702. The crane 11 provides the slip seat 1 with a traction force away from the winch 12, so that the taut wire rope 701 has sufficient tension, ensuring that the wire rope 7 can completely 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 have a better controllable shape, thereby improving the winding quality.

[0046] 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.
