Description

Technical Field

[0001] This utility model relates to the field of swing rope device technology, and in particular to a high-efficiency swing rope device for arranging steel wire ropes for drilling rigs. Background Technology

[0002] Common rope oscillators use a screw, chain, or crank mechanism to drive a guide wheel in reciprocating motion, achieving uniform wire rope winding on the drum. The rope oscillator is a key device to ensure orderly and tight wire rope winding, effectively preventing problems such as wire rope tangling, squeezing, and wear.

[0003] Existing wire rope retractors typically do not have an active clamping device when winding wire ropes, as their front end engages with the guide wheel. This means that the winding tightness of the wire rope cannot be actively adjusted during the winding process. For example, when drilling tools (such as drill pipes and drill collars) are completely placed at the bottom of the well or on a support platform, and the wire rope no longer bears any suspended weight, the lack of tension during recovery may cause the wire rope to become loose or tangled. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a high-efficiency wire rope arrangement swing device for drilling rigs, which increases the clamping force on the wire rope at the guide wheel, increases the wire rope winding force compensation between the guide wheel and the winding drum, and effectively improves the tight arrangement of the wire rope winding.

[0006] To achieve the above objectives, this utility model proposes a connecting frame, a winding mechanism, and a pressure swing mechanism. The winding mechanism is rotatably connected to the connecting frame through the partition. The pressure swing mechanism includes two symmetrical connecting plates, a first driving device, a moving frame, a guide wheel, and a pressing assembly. The two symmetrical connecting plates are disposed on the outer side of the connecting frame. The moving frame is movably connected between the symmetrical connecting plates via the first driving device. The guide wheel is rotatably connected to the moving frame. The pressing assembly is disposed on the connecting frame.

[0007] This utility model relates to a high-efficiency wire rope arrangement device for drilling rigs. Addressing the issue of stable, tension-free wire rope winding, it utilizes a clamping component at the guide wheel to adjust the wire rope's conveying pressure, thereby compensating for the winding pressure between the guide wheel and the winding drum. A torque detector in the winding mechanism measures the wire rope's winding torque, and in conjunction with the clamping component, controls the wire rope's winding force and adaptively adjusts its tightness. This effectively improves the wire rope's winding stability and reduces loosening and tangling issues during winding on the drum.

[0008] In addition, the high-efficiency wire rope arrangement swing rope device for drilling rigs proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the clamping assembly includes a support frame, a cylinder, a connecting frame, and a clamping wheel. The support frame is disposed on the connecting frame, the cylinder is disposed on the support frame, the connecting frame is movably connected to the support frame through the cylinder, and the clamping wheel is rotatably connected to the connecting frame.

[0010] Specifically, a partition is provided inside the connecting frame, dividing the connecting frame into a detection cavity and a winding cavity.

[0011] Specifically, the winding mechanism includes a second drive device, a torque detector, and a winding roller. The torque detector is disposed inside the detection cavity, the second drive device is disposed outside the connecting frame and connected to one end of the torque detector, and the winding roller is rotatably connected inside the winding cavity and connected to the other end of the torque detector.

[0012] Specifically, the support frame has limit grooves on both sides.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The following description, in conjunction with the accompanying drawings, describes the high-efficiency wire rope arrangement swing rope device for drilling rigs according to an embodiment of the present invention.

[0022] like Figures 1-4 As shown in the figure, the high-efficiency wire rope arrangement swing device for drilling rigs according to this utility model embodiment may include a connecting frame 1, a winding mechanism 2, and a pressure swing mechanism 3.

[0023] The winding mechanism 2 is rotatably connected to the connecting frame 1 through the partition 11. The pressure swing mechanism 3 includes two symmetrical connecting plates 31, a first driving device 32, a moving frame 33, a guide wheel 34, and a pressing assembly 35. The two symmetrical connecting plates 31 are located on the outside of the connecting frame 1. The moving frame 33 is movably connected between the symmetrical connecting plates 31 through the first driving device 32. The guide wheel 34 is rotatably connected to the moving frame 33. The pressing assembly 35 is located on the connecting frame 1.

[0024] It should be noted that the pressure swing assembly described in this embodiment pre-tightens the wire rope to be wound on the front side of the winding mechanism 2, and increases the friction on the wire rope through the pressure of the guide wheel 34 and the pressing assembly 35, thereby realizing the control of the winding force of the wire rope.

[0025] Specifically, during the actual winding process of the wire rope, the wire rope is retracted under no-load conditions, allowing it to be supported and guided by the guide wheel 34 and clamped by the clamping assembly 35 to increase the pre-tension of the wire rope winding. During the winding process of the winding mechanism 2, torque is detected, and the pressure between the clamping assembly 35 and the guide wheel 34 is adjusted according to the winding torque of the wire rope to compensate for the winding force and achieve stable winding of the wire rope. Then, the forward and reverse rotation of the first drive device 32 causes the moving frame 33 to drive the guide wheel 34 and the clamping assembly 35 to move synchronously back and forth between the symmetrical connecting plates 31 to achieve the winding and arrangement of the wire rope.

[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, the clamping assembly 35 includes a support frame 351, a cylinder 352, a connecting frame 353, and a clamping wheel 354.

[0027] The support frame 351 is mounted on the connecting frame 1, the cylinder 352 is mounted on the support frame 351, the connecting frame 353 is movably connected to the support frame 351 via the cylinder 352, and the pressing wheel 354 is rotatably connected to the connecting frame 353.

[0028] It should be noted that the guide wheel 34 rotates on the front side of the connecting frame 1 and is fixed in position to support the wire rope. The telescopic end of the cylinder 352 drives the connecting frame 353 and the pressing wheel 354 to slide up and down in the support frame 351, so that the pressing wheel 354 presses the wire rope radially on the guide wheel 34, thereby pressing the wire rope.

[0029] In one embodiment of this utility model, such as Figure 1 ,and Figure 4 As shown, a partition 11 is provided inside the connecting frame 1, which divides the connecting frame 1 into a detection cavity 12 and a winding cavity 13.

[0030] It should be noted that the partition 11 increases the installation stability of the torque tester 22, prevents the wire rope from breaking free of the guide wheel 34 during the winding process, and keeps the wire rope in the winding cavity 13, thus reducing the impact on the torque tester 22.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the winding mechanism 2 includes a second drive device 21, a torque detector 22, and a winding roller 23.

[0032] The torque tester 22 is located inside the test chamber 12, the second drive device 21 is located outside the connecting frame 1 and is connected to one end of the torque tester 22, and the take-up roller 23 is rotatably connected inside the take-up chamber 13 and is connected to the other end of the torque tester 22.

[0033] It should be noted that the second drive device 21 is a rotary motor, and the two ends of the torque detector 22 are connected to the winding roller 23 and the output end of the second drive device 21 respectively through couplings, which facilitates the detection of the winding torque of the winding roller 23.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the support frame 351 has limit grooves 3511 on both sides.

[0035] It should be noted that the limiting groove 3511 is used to limit the sliding of the connecting frame 353 and increase the moving stability of the clamping wheel 354.

[0036] In summary, the high-efficiency wire rope arrangement swing device for drilling rigs in this embodiment of the present invention increases the clamping force on the wire rope at the guide wheel 34, increases the wire rope winding force compensation between the guide wheel 34 and the winding drum, and effectively improves the tight arrangement of the wire rope winding.
