Description

Technical Field

[0001] This utility model relates to a tool used when installing or replacing a flat tail rope, specifically a flat tail rope torsion device for controlling the winding and unwinding direction and installation direction of the flat tail rope when installing or replacing it, belonging to the technical field of auxiliary process equipment for mine hoisting. Background Technology

[0002] In mine hoisting systems, balancing tail ropes are essential to balance the weight of the hoisting wire rope (also called the head rope) and reduce the tension difference between the hoisting and lowering sides. While the balancing tail rope itself does not bear the hoisting load, it plays a crucial role in the hoisting system. Problems with the balancing tail rope can also affect the normal operation of the hoisting system, causing production stoppages or even greater losses. Balancing tail ropes typically have two structures: flat tail ropes and round strand non-rotating ropes. Flat tail ropes, also known as flat wire ropes, are flat wire ropes woven from a certain number of strands (or sub-ropes) arranged parallel to each other on a plane and then woven with weft ropes to form a flat strip. Flat tail ropes are widely used in mine hoisting systems due to their absolute non-rotation and high weight per unit length. The main function of the flat tail rope is to balance the weight of the head rope. Although the flat tail rope does not bear the hoisting load during the mine hoisting process, it has a large exposed area and most of them are coreless structures. Therefore, the flat tail rope is susceptible to mechanical damage and corrosion from external substances. As a result, the flat tail rope also needs to be replaced and maintained regularly. The replacement of the flat tail rope is one of the most important tasks in mine shutdown maintenance.

[0003] Traditional methods of replacing flat tail ropes involve using electric rope storage carts, which are not only highly dangerous but also inefficient. Rope replacement carts, developed in recent years, offer significantly higher safety and efficiency for replacing wire ropes in mines. Flat tail rope replacement carts typically employ a linear friction drive structure consisting of upper and lower clamping components. After the flat tail rope is passed through the cart, the clamping and conveying action of the upper and lower clamping components, arranged in a roller configuration, retrieves the old flat tail rope and releases the new one. The flat tail ropes are suspended at the bottom of the hoisting container via a flat tail rope suspension device, with the flat surface of the rope facing the same direction as the hoisting container's door. Since mine cars transporting materials enter and exit the hoisting container through its doors, the locations where the surface or underground roadways meet the hoisting container doors are usually equipped with devices such as stabilizing platforms or tippers. Therefore, it is inconvenient to arrange equipment at the mine entrance corresponding to the hoisting container door for installing or replacing flat-tail ropes. Typically, when installing or replacing flat-tail ropes at the mine entrance, the equipment is arranged to the side of the hoisting container door. This means that when collecting old flat-tail ropes, the rope end removed from the bottom of the hoisting container above the mine entrance must first be twisted so that the flat surface of the old flat-tail rope aligns with the guide groove of the rope changing car's guide wheel before being fed into the rope changing car. Similarly, after placing a new flat-tail rope, the tail end of the new flat-tail rope must first be twisted so that the flat surface of the new flat-tail rope aligns with the direction of the hoisting container door before being installed and connected to the bottom of the hoisting container above the mine entrance. In existing technologies, the twisting operation of the flat tail rope end usually requires setting up a working platform at the wellhead, pulling the flat tail rope end with a hand-operated hoist, and twisting it manually. Since the flat tail rope has a large weight per unit length (the weight of a single flat tail rope is often in the ton range), this traditional method of manually twisting the flat tail rope end is not only time-consuming and labor-intensive, but also poses a great safety hazard. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a flat tail rope torsion device, which can automatically control the winding and installation direction of the flat tail rope during installation or replacement, thereby greatly reducing the safety hazards of twisting the rope head and improving the overall efficiency of flat tail rope installation or replacement. It is particularly suitable for flat tail rope installation or replacement operations.

[0005] To achieve the above objectives, this flat tail rope guide rope twisting device is located below the flat tail rope guide wheel. The flat tail rope guide wheel is rolled and fitted on the guide wheel support frame via a hinged mounting shaft, and the axial direction of the flat tail rope guide wheel is set along the left and right direction. This flat tail rope guide rope twisting device includes a tool support frame and a guide rope twisting tool installed on the tool support frame. The tool support frame is installed and connected to the guide wheel support frame via a tool support frame displacement control mechanism. By controlling the movement of the tool support frame displacement control mechanism, the tool support frame is controlled to drive the guide rope twisting tool to move in the front and back direction.

[0006] The rope twisting tool includes an outer support sleeve and an inner support sleeve arranged axially in the vertical direction. The outer support sleeve is installed on the tool support frame. The front end of the outer support sleeve has a notch that penetrates the cylinder wall in the front-back direction, and the width of the notch in the left-right direction matches the thickness of the flat tail rope. The inner support sleeve is coaxially and rollingly installed inside the outer support sleeve, and is axially positioned relative to the outer support sleeve. The front end of the inner support sleeve has a notch that penetrates the cylinder wall in the front-back direction, and the width of the notch in the left-right direction matches the thickness of the flat tail rope. The top of the inner support sleeve also has a rope clamping and limiting structure that cooperates with the notch. Between the outer and inner support sleeves, there is an inner support sleeve rotation control mechanism including a rotation drive component. By controlling the movement of the inner support sleeve rotation control mechanism, the rotational movement of the inner support sleeve relative to the outer support sleeve is controlled.

[0007] As a further improvement of this utility model, the inner support sleeve is also provided with a flat tail rope clamping mechanism. The flat tail rope clamping mechanism includes a clamping plate that is set in the opening and closing direction corresponding to the notch of the inner support sleeve and a clamping drive component that is connected to the clamping plate in a transmission manner. The clamping plate can be controlled to close or open by controlling the action of the clamping drive component.

[0008] As a further improvement of this utility model, the flat tail rope clamping mechanism is a structure for clamping the flat tail rope in one direction. The clamping plate includes a movable clamping plate and a stationary clamping plate fixedly connected to the inner support sleeve. The movable clamping plate is connected to the clamping drive component in a transmission manner. By controlling the action of the clamping drive component, the movable clamping plate can be controlled to move closer to or away from the stationary clamping plate.

[0009] Alternatively, the flat tail rope clamping mechanism is a bidirectional clamping structure for the flat tail rope. The clamping plate includes two symmetrically arranged movable clamping plates, and the movable clamping plates are connected to the clamping drive component. By controlling the action of the clamping drive component, the two movable clamping plates are synchronously controlled to move closer or further apart.

[0010] As a preferred embodiment of this utility model, the flat tail rope clamping mechanism is a wedge-shaped clamping structure. The flat tail rope clamping mechanism also includes a guide sliding panel that is inclinedly arranged corresponding to the notch of the inner support sleeve. The guide sliding panel is fixedly connected to the inner support sleeve, and the bottom end of the guide sliding panel is close to the axis of the inner support sleeve, while the top end of the guide sliding panel is far away from the axis of the inner support sleeve. The movable clamping plate of the clamping plate is a wedge-shaped structure that includes a vertically arranged clamping surface and an inclined wedge-shaped guide sliding surface, and the wedge-shaped guide sliding surface slides and cooperates with the guide sliding panel.

[0011] As a further improvement of this utility model, the axial length of the inner support sleeve is greater than that of the outer support sleeve. A locking mechanism is also provided outside the notch of the inner support sleeve. The locking mechanism includes a locking plate, a latch, and a latch driving component. Locking plates extending outward from the inner support sleeve are provided on both sides of the notch of the inner support sleeve. The locking plates are fixedly mounted on the inner support sleeve and are located outside the sleeve installation range of the outer support sleeve. A latch is provided on one side of the locking plate. The latch is connected to the latch driving component mounted on the inner support sleeve. By controlling the action of the latch driving component, the latch can be controlled to be in a locked state connected to the other side of the locking plate or in a yielding state away from the other side of the locking plate.

[0012] As one embodiment of this utility model, the latch is a swing-type locking structure, the latch driving component is a linear reciprocating motion driving structure, the latch driving component is hinged between the latch and the inner support sleeve, the latch is a hook-shaped structure, and the bottom end of the latch is hinged to the locking plate on one side. By controlling the movement of the latch driving component, the latch can be controlled to rotate and swing around its hinge center.

[0013] As a further improvement of this utility model, the axial length of the inner support sleeve is greater than that of the outer support sleeve. The inner support sleeve notch is also provided with a locking mechanism. The locking mechanism includes a locking plate. The two sides of the inner support sleeve notch are provided with locking plates that extend outward from the inner support sleeve. The locking plates are fixedly mounted on the inner support sleeve and are located outside the sleeve installation range of the outer support sleeve. The two locking plates are provided with detachable locking bolts.

[0014] As a further improvement of this utility model, the outer support sleeve is hingedly connected to the tool support frame.

[0015] As a further improvement of this utility model, the tool support frame is hinged to the guide rope wheel support frame, and one end of the tool support frame displacement control mechanism is hinged to the guide rope wheel support frame and the other end is hinged to the tool support frame. The tool support frame is controlled to swing in the front and back direction by controlling the movement of the tool support frame displacement control mechanism.

[0016] As a further improvement of this utility model, the hinged mounting shafts of the tool support frame and the guide rope wheel support frame and the flat tail rope guide wheel and the guide rope wheel support frame are coaxially arranged.

[0017] Compared with existing technologies, when using this flat tail rope torsion device to install or replace a flat tail rope, the extension of the control mechanism of the tool support frame moves the torsion device forward to the set position. The flat tail rope can then enter the inner support sleeve through the notches of the outer and inner support sleeves and be limited by the rope clamping and limiting structure at the top of the inner support sleeve. When it is necessary to adjust the winding and unwinding direction and installation direction of the flat tail rope, the rotation control mechanism of the inner support sleeve can be controlled to rotate forward or backward, so that the flat tail rope follows the forward or reverse rotation of the inner support sleeve. This achieves the alignment of the flat surface of the flat tail rope with the guide groove of the flat tail rope guide wheel or the alignment of the flat surface of the flat tail rope with the installation direction of the flat tail rope suspension device at the bottom of the lifting container, which can greatly improve efficiency. This system reduces the safety hazards associated with twisting the end of the flat tail rope and improves the overall efficiency of flat tail rope installation or replacement. Because the inner support sleeve contains a flat tail rope clamping mechanism, the clamping drive component can be controlled to keep the clamping plate in an open, non-clamped state during normal rope transport. When positioning the flat tail rope at the wellhead, the clamping drive component can be controlled to keep the clamping plate in a closed, clamped state. This allows for direct positioning of the flat tail rope through the clamping mechanism, eliminating the cumbersome operation of installing a positioning clamp at the wellhead. In case of pulley or rope slippage, the clamping drive component can be controlled to keep the clamping plate in a closed, clamped state, effectively preventing further slippage of the flat tail rope. This system is particularly suitable for flat tail rope installation or replacement operations. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings (the axial direction of the flat tail rope guide wheel 3 is used as the left and right direction in the following description).

[0026] like Figure 1 , Figure 3 As shown, the flat tail rope guide wheel 3 is rolled and fitted onto the guide wheel support frame 4, and the axial direction of the flat tail rope guide wheel 3 is set along the left-right direction. This flat tail rope torsion device is located below the flat tail rope guide wheel 3, including a tool support frame 1 and a torsion device 2 mounted on the tool support frame 1. The tool support frame 1 is connected to the guide wheel support frame 4 via a tool support frame displacement control mechanism 11 set along the front-back direction. The tool support frame displacement control mechanism 11 can be a telescopic cylinder structure, or a gear and rack transmission structure or other linear reciprocating motion structure. By controlling the movement of the tool support frame displacement control mechanism 11, the tool support frame 1 can be controlled to drive the torsion device 2 to move along the front-back direction. The installation method of the tool support frame 1 and the guide wheel support frame 4 can be as follows: Figure 1 , Figure 3 The swing hinge connection shown is a type where the tool support frame 1 and the guide rope wheel support frame 4 are hinged together. One end of the tool support frame displacement control mechanism 11 is hinged to the guide rope wheel support frame 4, and the other end is hinged to the tool support frame 1. The hinge mounting shafts of the tool support frame 1 and the guide rope wheel support frame 4 and the flat tail rope guide wheel 3 and the guide rope wheel support frame 4 can be coaxially arranged. Alternatively, the tool support frame 1 and the guide rope wheel support frame 4 can be installed in a translational connection via a guide translation mechanism. In this case, the tool support frame 1 slides and is fitted onto the guide rope wheel support frame 4 in the front-to-back direction. One end of the tool support frame displacement control mechanism 11 is installed and connected to the guide rope wheel support frame 4, and the other end is installed and connected to the tool support frame 1.

[0027] like Figure 2 , Figure 4As shown, the rope twisting device 2 includes an outer support sleeve 21 and an inner support sleeve 22 arranged axially in the up-down direction. The outer support sleeve 21 is installed on the device support frame 1. The front end of the outer support sleeve 21 has a notch 211 that penetrates the cylinder wall in the front-back direction, and the width of the notch 211 in the left-right direction matches the thickness of the flat tail rope of the flat strip structure. The inner support sleeve 22 is coaxially and rollingly installed inside the outer support sleeve 21, and the inner support sleeve 22 is axially positioned relative to the outer support sleeve 21. The front end of the inner support sleeve 22 has a notch 221 that penetrates the cylinder wall in the front-back direction, and the width of the notch 221 in the left-right direction matches the thickness of the flat tail rope of the flat strip structure. The top of the inner support sleeve 22... The end is also provided with a rope clamping and limiting structure that cooperates with the notch 221 of the inner support sleeve. The rope clamping and limiting structure can be a cover structure including a groove structure, or a vertical plate structure arranged in parallel and vertically spaced, or other structures that can allow the flat tail rope to be clamped and limited. Between the outer support sleeve 21 and the inner support sleeve 22, there is also an inner support sleeve rotation control mechanism including a rotation drive component (the inner support sleeve rotation control mechanism is not shown in the figure for the sake of showing the rotation angle of the inner support sleeve 22 relative to the outer support sleeve 21). The inner support sleeve rotation control mechanism can be a gear ring transmission structure that is matched, or a worm gear transmission structure that is matched, or other rotation control structures. By controlling the action of the inner support sleeve rotation control mechanism, the rotation of the inner support sleeve 22 relative to the outer support sleeve 21 can be controlled.

[0028] When installing or replacing the flat tail rope, the guide wheel support frame 4 can be directly fixed on the wellhead surface for independent use. In this case, the flat tail rope changing cart needs to be moved in coordination with the installation position of the guide wheel support frame 4. Alternatively, the guide wheel support frame 4 can be directly installed at the front end of the flat tail rope changing cart and move with it. In this case, only the flat tail rope changing cart needs to be moved according to the installation or replacement requirements of the flat tail rope. Taking the guide wheel support frame 4 installed at the front end of the flat tail rope changing cart as an example, the rear end of the guide wheel support frame 4 can be hinged to the front end of the flat tail rope changing cart through a vertically set hinge pin. When the flat tail rope changing cart is in the transfer state, the guide wheel support frame 4 can be controlled to swing backward, fold, and position itself. When installing or replacing the flat tail rope, the guide wheel support frame 4 can be controlled to swing forward and position itself so that the flat tail rope guide wheel 3 is positioned directly in front of the flat tail rope changing cart.

[0029] Taking the replacement of a flat tail rope as an example: In the initial state, the rope twisting device 2 is located directly below the flat tail rope guide wheel 3, and the inner support sleeve notch 221 faces the outer support sleeve notch 211; first, control the hoisting container I to be raised to the set position above the wellhead, and the flat tail rope replacement vehicle is positioned at the wellhead; when collecting the old flat tail rope, remove the old flat tail rope end located at the bottom of the hoisting container II in the well, and loosen the entire old flat tail rope, as follows... Figure 1 , Figure 2 As shown, the extension action of the control tool support frame displacement control mechanism 11 causes the rope twisting tool 2 to move forward to the set position. The old flat tail rope can then enter the inner support sleeve 22 through the outer support sleeve notch 211 and the inner support sleeve notch 221, and be limited by the rope clamping limit structure at the top of the inner support sleeve 22. After the old tail rope is positioned at the wellhead, the hoisting container I located above the wellhead is lowered a set distance and positioned, causing the old flat tail rope segment below it to loosen. Then, the old flat tail rope end at the bottom of the hoisting container I is disassembled and lowered into the wellhead. Simultaneously, the retraction action of the control tool support frame displacement control mechanism 11 controls the forward action of the inner support sleeve rotation control mechanism, as shown. Figure 3 , Figure 4 As shown, while the rope twisting device 2 moves backward to reset, the inner support sleeve 22 rotates in the forward direction relative to the outer support sleeve 21 to an appropriate angle corresponding to the flat tail rope guide wheel 3. The old flat tail rope can then follow the forward rotation of the inner support sleeve 22, causing its flat surface to align with the guide groove of the flat tail rope guide wheel 3 and engage in the guide groove. The old flat tail rope end is then fed into the flat tail rope changing vehicle. After releasing the old flat tail rope from the wellhead positioning, the flat tail rope changing vehicle is started to retrieve the old flat tail rope. The rope twisting device 2 ensures that the old flat tail rope is securely engaged in the guide groove of the flat tail rope guide wheel 3. When releasing the new flat tail rope, the new flat tail rope sent out by the flat tail rope changing vehicle is guided by the flat tail rope guide wheel 3 and then fed into the inner support sleeve 22 through the rope clamping and limiting structure at the top of the inner support sleeve 22. The rope twisting device 2 ensures the stability of the new flat tail rope during descent. The new flat tail rope is lowered to the designated position. After determining the length, the new tail rope is positioned at the wellhead. The flat tail rope changing machine ejects the new flat tail rope head and sends it to the bottom of the hoisting container I. While controlling the extension of the tool support frame displacement control mechanism 11, the inner support sleeve rotation control mechanism is controlled to move in the opposite direction. This causes the rope twisting tool 2 to move forward a set distance while the inner support sleeve 22 rotates in the opposite direction relative to the outer support sleeve 21 to an appropriate angle corresponding to the flat tail rope installation position. The new flat tail rope then follows the inner support sleeve 22 in the opposite direction, making its flat surface correspond to the flat tail rope installation position. After connecting the new flat tail rope head at the wellhead to the bottom of the hoisting container I, the wellhead positioning of the new flat tail rope is released. The hoisting container I above the wellhead is then raised a set distance and positioned. Finally, the new flat tail rope head below the wellhead is connected to the bottom of the hoisting container II.

[0030] To further enhance safety when reeling in and out of the flat tail rope, as a further improvement to this utility model, such as... Figure 2 , Figure 4 , Figure 5As shown, the inner support sleeve 22 is also equipped with a flat tail rope clamping mechanism 23. The flat tail rope clamping mechanism 23 includes a clamping plate 231 with the opening and closing direction corresponding to the notch 221 of the inner support sleeve, and a clamping drive component 232 that is connected to the clamping plate 231. The clamping drive component 232 can be a telescopic cylinder structure or a screw and nut structure or other linear reciprocating drive structure. By controlling the action of the clamping drive component 232, the closing or opening action of the clamping plate 231 can be controlled. When collecting old flat tail ropes or releasing new flat tail ropes, the clamping drive component 232 can be controlled to keep the clamping plate 231 in an open, non-clamping state during the normal transport of the flat tail rope. When positioning the flat tail rope at the wellhead, the clamping drive component 232 can be controlled to keep the clamping plate 231 in a closed clamping state. That is, the flat tail rope can be positioned directly through the flat tail rope clamping mechanism 23, which can eliminate the complicated operation of positioning the flat tail rope at the wellhead by installing a positioning clamp.

[0031] As an embodiment of the flat tail rope clamping mechanism 23 of this utility model, the flat tail rope clamping mechanism 23 can be a structure that clamps the flat tail rope in one direction. That is, the clamping plate 231 includes a movable clamping plate and a stationary clamping plate fixedly connected to the inner support sleeve 22, and the movable clamping plate is driven by the clamping drive component 232. By controlling the action of the clamping drive component 232, the movable clamping plate can be controlled to move closer to or away from the stationary clamping plate; for example Figure 5 As shown, the flat tail rope clamping mechanism 23 can also be a bidirectional clamping structure for the flat tail rope. That is, the clamping plate 231 includes two symmetrically arranged movable clamping plates, and the movable clamping plates are connected to the clamping drive component 232 in a transmission manner. By controlling the action of the clamping drive component 232, the two movable clamping plates can be synchronously controlled to move closer or further apart.

[0032] The flat tail rope clamping mechanism 23 can clamp the rope by controlling the horizontal translation of the clamping plate 231, or by controlling the translation of the clamping plate 231 along the wedge-shaped surface. Since the wedge-shaped clamping method can produce a wedge-shaped self-locking effect in the event of a pulley or rope slippage, thus preventing the flat tail rope from continuing to fall, the latter is preferred. Therefore, as the preferred solution of this utility model, Figure 5As shown, the flat tail rope clamping mechanism 23 also includes a guide sliding panel 233 inclinedly arranged corresponding to the inner support sleeve notch 221. The guide sliding panel 233 is fixedly connected to the inner support sleeve 22, and the bottom end of the guide sliding panel 233 is close to the axis of the inner support sleeve 22, while the top end of the guide sliding panel 233 is far from the axis of the inner support sleeve 22. The movable clamping plate of the clamping plate 231 is a wedge-shaped structure including a vertically arranged clamping surface and an inclined wedge-shaped guide sliding surface, and the wedge-shaped guide sliding surface slides in cooperation with the guide sliding panel 233. To ensure that the clamping plate 231 moves accurately up and down along the guide sliding panel 233, a guide sliding structure is also provided between the wedge-shaped guide sliding surface of the clamping plate 231 and the guide sliding panel 233. The guide sliding structure can be a dovetail groove and a dovetail protrusion that fit together, or it can be a T-shaped groove and a T-shaped block or other linear reciprocating guide sliding structure that fits together. When a pulley or rope slippage occurs, the clamping drive component 232 can be controlled to keep the clamping plate 231 in a closed clamping state. The wedge-shaped self-locking effect can more effectively prevent the flat tail rope from continuing to slip.

[0033] When using a wedge structure for clamping, due to the presence of the inner support sleeve notch 221 and the outer support sleeve notch 211, to avoid excessive reaction force from the wedge clamping force causing tearing and deformation of the inner support sleeve 22 and the outer support sleeve 21, a further improvement of this utility model is as follows: Figure 6 As shown, the axial length of the inner support sleeve 22 is much larger than that of the outer support sleeve 21. A locking mechanism is also provided outside the notch 221 of the inner support sleeve. The locking mechanism includes a locking plate 222, a latch 223, and a latch drive component 224. Locking plates 222 extending outwards from both sides of the notch 221 of the inner support sleeve are provided. The locking plates 222 are fixedly mounted on the inner support sleeve 22, and the locking plates 222 are located within the sleeved installation of the outer support sleeve 21. Outside the range, a latch 223 is provided on one side of the locking plate 222. The latch 223 is connected to the latch drive component 224 installed on the inner support sleeve 22. The latch drive component 224 can be a linear reciprocating motion drive structure such as a telescopic cylinder structure, or a rotary motion drive structure such as a motor. By controlling the action of the latch drive component 224, the latch 223 can be controlled to be in a locked state connected to the other side of the locking plate 222 or in a yielding state away from the other side of the locking plate 222. Taking the collection of old flat tail rope as an example, the locking buckle drive component 224 can be controlled to make the locking buckle 223 move away from the other side locking plate 222 in a yielding state. Then, the rope twisting device 2 can be controlled to move forward to the set position so that the old flat tail rope enters the outer support sleeve notch 211 and the inner support sleeve notch 221. After the old flat tail rope enters the inner support sleeve 22, the locking buckle drive component 224 can be controlled to make the locking buckle 223 lock in a locked state connected to the other side locking plate 222.

[0034] As an embodiment of the locking structure of the latch 223 and the locking plate 222 of this utility model, the latch 223 can adopt a swing-type locking structure, that is, as shown in the figure. Figure 6 As shown, the latch drive component 224 is a linear reciprocating motion drive structure such as a telescopic cylinder. The latch drive component 224 is hinged between the latch 223 and the inner support sleeve 22. The latch 223 has a hook-shaped structure, and its bottom end is hinged to one side of the lock plate 222. By controlling the telescopic movement of the latch drive component 224, the latch 223 can be controlled to rotate and swing around its hinge center, thereby controlling the latch 223 to be either locked on the other side of the lock plate 222 or in a yielding state away from the other side of the lock plate 222. The latch 223 can adopt a linear motion locking structure, that is, the latch driving component 224 is a rotary motion driving structure such as a motor or electric motor, the latch 223 is a threaded rod structure, and the threaded rod latch 223 is threadedly connected to the locking plate 222. By controlling the forward and reverse rotation of the latch driving component 224, the linear reciprocating motion of the threaded rod latch 223 can be controlled, thereby controlling the threaded rod latch 223 to be in a locked state screwed into the locking plate 222 on the other side or in a yielding state screwed out away from the locking plate 222 on the other side.

[0035] When using a wedge structure for clamping, to avoid excessive reaction force of the wedge clamping force causing tearing and deformation of the inner support sleeve 22 and the outer support sleeve 21, as a further improvement of this utility model, the axial length of the inner support sleeve 22 is much larger than the axial length of the outer support sleeve 21. A locking mechanism is also provided outside the notch 221 of the inner support sleeve. The locking mechanism includes a locking plate 222. Locking plates 222 are provided on both sides of the notch 221 of the inner support sleeve, extending outward from the inner support sleeve 22. The locking plates 222 are fixedly mounted on the inner support sleeve 22 and are located outside the sleeve installation range of the outer support sleeve 21. The two locking plates 222 are provided with detachable locking bolts. Taking the collection of old flat tail rope as an example, control the rope twisting machine 2 to move forward to the set position so that the old flat tail rope enters the outer support sleeve notch 211 and the inner support sleeve notch 221. After the old flat tail rope enters the inner support sleeve 22, manually install locking bolts on the two locking plates 222 to lock the locking plates 222.

[0036] When the flat tail rope enters the notch 211 of the outer support sleeve and the notch 221 of the inner support sleeve, in order to realize the adaptive swing fine adjustment of the rope twisting tool 2 and facilitate the entry of the flat tail rope, as a further improvement of this utility model, the outer support sleeve 21 is hingedly connected to the tool support frame 1, and the center line of gravity of the entire rope twisting tool 2 is collinear with the central axis of the outer support sleeve 21.

[0037] When installing or replacing a flat tail rope using this flat tail rope torsion device, it can automatically control the alignment of the flat surface of the flat tail rope with the guide groove of the flat tail rope guide wheel 3, or the alignment of the flat surface of the flat tail rope with the installation direction of the flat tail rope suspension device at the bottom of the hoisting container. This can greatly reduce the safety hazards of the flat tail rope torsion operation and improve the overall efficiency of flat tail rope installation or replacement. At the same time, the flat tail rope can be positioned directly through the flat tail rope clamping mechanism 23, eliminating the complicated operation of positioning the flat tail rope at the wellhead by installing positioning clamps. In the event of pulley or rope slippage, it can also effectively prevent the flat tail rope from continuing to slide down. It is particularly suitable for the installation or replacement of flat tail ropes.
