Description
Technical Field
[0001] This utility model relates to the field of cable winding and unwinding for drilling rigs, and in particular to a cable winding and unwinding device that can automatically wind and unwind cables. Background Technology
[0002] During drilling operations, the drilling rig operates remotely and constantly changes position, while the power module providing power remains stationary. Therefore, the length of the cable connecting the power module and the drilling rig changes with the rig's location. A cable retraction device solves this problem by neatly arranging the cable and continuously retracting it as the drilling rig moves, eliminating redundant cables between the power module's cable junction box and the rig.
[0003] The current cable winding and unwinding device mainly consists of a frame with guide rails, multiple trolleys, a power winch, wire rope, a rope arranger, and chains. Specifically: the guide rails are located at the top of the frame and arranged along its length; multiple trolleys are suspended on the guide rails and can slide along them; adjacent trolleys are connected by chains; the power winch is fixed at one end of the frame, the cable transfer cabinet is installed on a trolley near the other end of the frame, and cable trays are installed on the remaining trolleys, with the cable resting on the trays and the trays fixed in place; the rope arranger is fixed at the top of the frame near the power winch, one end of the wire rope passes through the rope arranger and connects to the power winch, and the other end of the wire rope connects to the cable transfer cabinet; the specific operation is as follows.
[0004] When the cable is laid out, the cable transfer cabinet is moved toward the drilling rig body by external force or external machinery (manual traction or trailer traction), thereby pulling other pulleys toward the drilling rig body by chain traction, so as to realize the cable laying out within the frame.
[0005] When the cable is being retrieved, the power winch is started directly to wind up the wire rope. The wire rope pulls the cable transfer cabinet to the location of the power winch, thereby pushing other pulleys to the location of the power winch, further realizing the cable retrieval frame.
[0006] As can be seen from the above, current cable winding and unwinding devices require external force or machinery, making operation cumbersome, affecting efficiency, and increasing workload. Therefore, improvements to the cable winding and unwinding devices are necessary. Utility Model Content
[0007] The purpose of this utility model is to address the aforementioned problems by providing a cable deployment and retraction system for drilling rigs that eliminates the need for external machinery during cable deployment and retraction, effectively simplifying the cable deployment and retraction process, reducing workload, and improving work efficiency.
[0008] The technical solution adopted by this utility model is as follows: A cable winding and unwinding device that can automatically wind and unwind cables includes a frame, a guide rail is provided on the top of the frame and along the length of the frame, a power winch assembly is fixed at one end of the frame and the power winch assembly is located at one end of the guide rail; multiple trolleys are slidably connected on the guide rail, a cable transfer cabinet is installed on the trolley farthest from the power winch assembly, and cable brackets are installed on the other trolleys; adjacent trolleys are connected by chains;
[0009] One or two steel wire ropes are installed between the cable transfer cabinet and the power winch assembly; wherein:
[0010] If a steel wire rope is installed between the cable transfer cabinet and the power winch assembly, one end of the steel wire rope is connected to the power winch assembly, and the other end is directly connected to the cable transfer cabinet, or the other end is routed around the fixed pulley on the drilling rig body and connected to the cable transfer cabinet.
[0011] If two steel wire ropes are installed between the cable transfer cabinet and the power winch assembly, these two steel wire ropes are respectively the outgoing steel wire rope and the retracting steel wire rope. One end of the outgoing steel wire rope and the retracting steel wire rope are connected to the power winch assembly, and the other end of the outgoing steel wire rope goes around the fixed pulley on the main body of the drilling rig and connects to one side of the cable transfer cabinet; the other end of the retracting steel wire rope is directly connected to the other side of the cable transfer cabinet.
[0012] Furthermore, it also includes a rope arranger, which is installed on the top of the frame and close to the power winch assembly. One end of the outgoing wire rope and the retracting wire rope passes around the rope arranger and connects to the power winch assembly.
[0013] Furthermore, if a steel wire rope is installed between the cable transfer cabinet and the power winch assembly, the power winch assembly is an electric winch; if two steel wire ropes are installed between the cable transfer cabinet and the power winch assembly, the power winch assembly consists of two electric winches, one of which is a retraction power winch connected to the retraction steel wire rope, and the other is an outward power winch connected to the outward release steel wire rope.
[0014] Furthermore, the power winch assembly is a double-drum winch capable of automatic cable routing, with the retrieved wire rope connected to one drum of the double-drum winch and the released wire rope connected to the other drum of the double-drum winch.
[0015] Furthermore, the power winch assembly is a double-drum winch capable of automatic cable routing. The double-drum winch has two independent drums. The recovery wire rope is connected to one drum of the double-drum winch, and the release wire rope is connected to the other drum of the double-drum winch.
[0016] Furthermore, the rope guide has at least one support pulley; the support pulley supports the retracting wire rope and / or the outgoing wire rope, and the maximum angle between the retracting wire rope and the outgoing wire rope after they are supported is no higher than 10°.
[0017] Furthermore, the number of the rope arrangers is at least one, and the retracting wire rope and the outgoing wire rope are each supported by at least one support pulley on the same rope arranger; or / and the retracting wire rope and the outgoing wire rope are each supported by at least one rope arranger.
[0018] Furthermore, the supporting pulley has limiting protrusions on both sides.
[0019] Furthermore, it also includes an electrical control system, which includes a remote controller connected to the power winch unit.
[0020] Furthermore, the electrical control system also includes a camera mounted on the cable junction box, which is connected to a remote controller.
[0021] Furthermore, the electrical control system also includes two proximity switches and a sensing structure for multiple proximity switches, with the multiple sensing structures arrayed along a guide rail. The two proximity switches are respectively located on both sides of the cable transfer cabinet; both proximity switches are connected to a remote controller.
[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0023] This invention employs one or two steel wire ropes. When using one steel wire rope, it is simply connected to the cable transfer cabinet by looping it around the fixed pulley on the drilling rig body. Driven by a power winch, the cable transfer cabinet is pulled towards the drilling rig body, thus releasing the cable. When using two steel wire ropes, the cable is released and retrieved by extending and retracting the steel wire ropes, both driven by the power winch. Neither solution requires external machinery, effectively simplifying cable deployment and retrieval operations, reducing workload, and improving work efficiency. Attached Figure Description

[0034] Furthermore, the use of terms such as "horizontal" or "vertical" in this specification does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0035] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.
[0036] Example 1
[0037] like Figures 1-7 As shown, a cable winding and unwinding device capable of automatically winding and unwinding cables includes a frame 6, a guide rail 5 arranged on the top of the frame 6 and along the length of the frame 6, a power winch assembly fixed to one end of the frame 6, and the power winch assembly located at one end of the guide rail 5; multiple trolleys 4 are slidably connected on the guide rail 5, a cable transfer cabinet 9 is installed on the trolley 4 farthest from the power winch assembly, and cable 7 brackets are installed on the other trolleys 4; adjacent trolleys 4 are connected by chains 8.
[0038] One or two steel wire ropes are installed between the cable transfer cabinet 9 and the power winch assembly; wherein:
[0039] One implementation method, such as Figures 1-2 As shown, if a steel wire rope is installed between the cable transfer cabinet 9 and the power winch assembly, one end of the steel wire rope is connected to the power winch assembly, and the other end is directly connected to the cable transfer cabinet 9, or the other end is routed around the fixed pulley 11 on the drilling rig body 10 and connected to the cable transfer cabinet 9. The specific operation is as follows.
[0040] like Figure 1 As shown, when cable 7 is laid out, a fixed pulley 11 needs to be installed on the main body 10 of the drilling rig first. The wire rope 2 passes around the fixed pulley 11 and is connected to the cable transfer cabinet 9. The power winch 1 is started to wind up the wire rope 2, so that the cable transfer cabinet 9 moves to the location of the main body 10 of the drilling rig, thereby pulling other pulleys 4 to move to the main body 10 of the drilling rig through the chain 8, so as to realize the laying out of cable 7 in the frame 6.
[0041] like Figure 2 As shown, when cable 7 is retracted, the wire rope 2 is directly connected to the cable transfer cabinet 9 (or to the trolley 4 on which the cable transfer cabinet 9 is installed); the power winch 1 is started to wind up the wire rope 2, so that the cable transfer cabinet 9 moves to the position of the power winch 1, thereby pushing other trolleys 4 to move to the position of the power winch 1, further realizing the cable 7 retraction frame 6.
[0042] Another implementation, such as Figures 3-4As shown, if two steel wire ropes are installed between the cable transfer cabinet 9 and the power winch assembly, these two steel wire ropes are respectively the outgoing steel wire rope 15 and the retracting steel wire rope 16. One end of the outgoing steel wire rope 15 and the retracting steel wire rope 16 is connected to the power winch assembly, and the other end of the outgoing steel wire rope 15 passes around the fixed pulley 11 on the drilling rig body 10 and is connected to one side of the cable transfer cabinet 9; the other end of the retracting steel wire rope 16 is directly connected to the other side of the cable transfer cabinet 9. By using the outgoing steel wire rope 15 and the retracting steel wire rope 16, the cable transfer cabinet 9 is provided with the power to move when the cable 7 is retracted and when the cable 7 is outgoing, respectively. There is no need to remove the steel wire rope 2 and then reinstall the steel wire rope 2, which effectively simplifies the operation of cable 7 retraction and release, reduces workload, and improves work efficiency. The specific working process is as follows.
[0043] When cable 7 is being released, the power winch is started to wind up the released steel wire rope 15, causing the cable transfer cabinet 9 to move toward the location of the drilling rig body 10. This causes the chain 8 to pull other pulleys 4 toward the drilling rig body 10, thus realizing the release of cable 7 from within the frame 6.
[0044] When cable 7 is being retracted, the power winch unit is activated to retract the wire rope 16, causing the cable transfer cabinet 9 to move toward the power winch unit, thereby pushing other trolleys 4 to move toward the location of the power winch unit, further realizing the cable 7 retraction frame 6.
[0045] In summary, both solutions provided in this embodiment do not require external machinery, effectively simplifying cable winding and unwinding operations, reducing workload, and improving work efficiency.
[0046] Example 2
[0047] Based on Example 1, further feasible implementation methods are proposed.
[0048] The cable 7 winding and unwinding device also includes a rope arranger 3, which is installed on the top of the frame 6 and close to the power winch assembly. One end of the outgoing wire rope 15 and the retracting wire rope 16 passes around the rope arranger 3 and is connected to the power winch assembly. The rope arranger 3 supports the outgoing wire rope 15 and the retracting wire rope 16 and keeps them separate from each other, preventing them from getting tangled and affecting the movement, thus ensuring the smooth movement of the wire rope 2.
[0049] Example 3
[0050] Based on Example 2, further feasible implementation methods are proposed.
[0051] Regarding the "powered winch assembly", the following implementation methods are proposed in this embodiment.
[0052] The first implementation method, such as Figures 1-2As shown, if a steel wire rope 2 is installed between the cable transfer cabinet 9 and the power winch assembly, and the power winch assembly is an electric winch, the traction force of the steel wire rope is provided by the power winch 1.
[0053] The second implementation method, such as Figure 3 As shown, if two steel wire ropes are installed between the cable transfer cabinet 9 and the power winch group, the power winch group consists of two electric winches, one of which is a retraction power winch 13, which is connected to the retraction steel wire rope 16 and is used to wind up the retraction steel wire rope 16; the other is an outward power winch 12, which is connected to the outward steel wire rope 15 and is used to wind up the outward steel wire rope 15.
[0054] It should be noted that neither of the two power winches 1 has a self-locking mechanism to ensure that the released wire rope 15 can be released when the wire rope 16 is wound up and retracted, and that the retracted wire rope 16 can be released when the wire rope 15 is wound up and retracted.
[0055] The third implementation method, such as Figure 4 As shown, if two steel wire ropes are installed between the cable transfer cabinet 9 and the power winch group, the power winch group is a double-drum winch 17 capable of automatic cable routing. The double-drum winch 17 has two drums and also has a motor. The output of the motor can be switched by a clutch to achieve independent drive of different drums; for example, the Chinese patent with publication number "CN214359954U" discloses "A Double-Drum Intelligent Winch"; one drum winds the retracted steel wire rope 16 in the forward direction, and the other drum winds the outward-releasing steel wire rope 15 in the reverse direction; when the winch rotates in the forward direction, the retracted steel wire rope 16 is released, the outward-releasing steel wire rope 15 is wound up, the cable transfer cabinet 9 moves towards the drilling rig body 10, and the cable 7 is released; when the winch rotates in the reverse direction, the retracted steel wire rope 16 is wound up, the outward-releasing steel wire rope 15 is released, the cable transfer cabinet 9 moves towards the power winch group, and the cable 7 is retracted.
[0056] In one feasible implementation, the number of rope arrangers 3 is at least one, and each rope arranger 3 has at least one support pulley 14. When a rope arranger 3 has two support pulleys 14, supporting the retracting wire rope 16 and the extending wire rope 15 respectively, in this structure, the number of rope arrangers 3 can be one or more, and the two support pulleys 14 on the remaining rope arrangers 3 also support the retracting wire rope 16 and the extending wire rope 15 respectively. Alternatively, in another implementation, the rope arranger 3 has only one support pulley 14. In this structure, the number of rope arrangers 3 is at least two, with two rope arrangers 3 supporting the retracting wire rope 16 and the extending wire rope 15 respectively, and the remaining rope arrangers 3 supporting the retracting wire rope 16 and / or the extending wire rope 15. Of course, a rope arranger with two support pulleys 14 and a rope arranger with one support pulley 14 can simultaneously support the retracting wire rope 16 and / or the extending wire rope 15.
[0057] In one feasible implementation, after the retractable wire rope 16 and the extended wire rope 15 are supported, the maximum angle between them is no higher than 10°. That is, when the cable 7 is in a fully extended state, the angle α between the retractable wire rope 16 and the extended wire rope 15 is less than 10°; when the cable 7 is in a fully retracted state, the angle α between the retractable wire rope 16 and the extended wire rope 15 is no higher than 10°. This is to avoid the wire rope 2 being subjected to excessive lateral force from the supporting pulley 14, which would affect the rope laying.
[0058] In one feasible implementation, the support pulley 14 has limiting protrusions 20 on both sides, and the limiting protrusions 20 limit the support pulley 14.
[0059] Example 4
[0060] Based on any one of the implementation methods in Examples 1-3, further feasible specific implementation methods are proposed.
[0061] One feasible implementation method is, for example Figure 5 As shown, the cable 7 winding and unwinding device also includes an electrical control system, which includes a remote controller connected to a power winch assembly. Management personnel can control the operation of the power winch assembly through the remote controller, thereby realizing remote control of the winding and unwinding of the cable 7.
[0062] Furthermore, the electrical control system also includes a camera installed on the cable transfer cabinet 9, which is connected to a remote controller to enable remote monitoring of the cable transfer cabinet 9.
[0063] Furthermore, the electrical control system also includes two proximity switches 19 and a sensing structure 18 for multiple proximity switches 19. The multiple sensing structures 18 are arrayed along the guide rail 5, and the two proximity switches 19 are respectively set on both sides of the cable transfer cabinet 9. Both proximity switches 19 are connected to a remote controller. When the proximity switch 19 passes the sensing structure 18, it will generate a signal, which will be fed back to the remote controller. The order in which the two proximity switches 19 generate signals can be used to determine whether the cable transfer cabinet 9 is in the state of cable 7 retracted or cable 7 extended. The number of times the signal is generated can reflect the distance that the cable transfer cabinet 9 moves on the guide rail 5, thereby realizing real-time control.
[0064] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
