Description

Technical Field

[0001] The invention relates to a wire rope releasing device, in particular to a wire rope damping releasing device for releasing the wire rope when replacing the wire rope in a mine, and belongs to the technical field of mining equipment. Background Art

[0002] Mine hoisting systems are crucial for transporting personnel, equipment, or materials. Once a mine is operational, some of the system's hoisting facilities and shaft equipment must be regularly replaced to ensure safe production. For example, wire ropes used for lifting materials, balancing wire ropes, and brake ropes (including buffer ropes) for fall arresters must be replaced if the ratio of broken wire cross-sectional area to total wire cross-sectional area within a lay length reaches 10%. If the wire rope is severely corroded, pitted, or grooved, or if the outer wire is loose, the system must be replaced immediately, regardless of the number of broken wires or changes in rope diameter.

[0003] Wire rope replacement in mine hoisting systems typically involves reeling in the old rope and deploying the new one. During this process, the rope must be locked at all times to prevent slipping and rolling. However, as mine hoisting systems increase their lifting loads and shaft depths, the diameter and length of the wire ropes used are also increasing. This requires more extensive equipment to replace the ropes, a particularly significant issue when replacing tank ropes. Multiple large stabilizing machines are often required to complete the rope retraction and deployment, resulting in high costs and low efficiency. Summary of the Invention

[0004] In response to the problems existing in the above-mentioned prior art, the present invention provides a wire rope damping release device, which can rely on mechanical structure to achieve damping release and can adjust the damping force according to the required braking force. The whole machine is easy to install and operate, and is particularly suitable for wire rope replacement operations in mine hoisting systems.

[0005] In order to achieve the above-mentioned purpose, the wire rope damping rope releasing device includes a wire rope accommodating drum which is installed between the left support frame and the right support frame in a rolling cooperation manner;

[0006] The wire rope accommodating drum is provided with a damping application adjustment mechanism, which includes an adjusting shaft, a force adjusting wheel and a damping adjustment assembly. The damping adjustment assembly includes a supporting inner cylinder, a compression spring, a movable disc, a brake friction plate, a static disc and a support. The supporting inner cylinder is coaxially fixed in the wire rope accommodating drum, and the adjusting shaft is coaxially connected and mounted on the supporting inner cylinder through the support. The force adjusting wheel is connected to the axial end of the adjusting shaft. The static disc, brake friction plate, movable disc and compression spring located inside the supporting inner cylinder are sequentially sleeved on the adjusting shaft from the outside to the inside. The movable disc is radially positioned and axially slidably arranged relative to the supporting inner cylinder. The static disc is positioned relative to the left support frame or the right support frame. One end of the compression spring is connected to the movable disc through the rotary disk, and the other end is connected to the adjusting shaft.

[0008] As a further improvement of the present invention, the force regulating wheel is connected to the shaft end of the regulating shaft through a trapezoidal thread.

[0009] As a further improvement of the present invention, the damping adjustment components are coaxially arranged in series in multiple groups, and the multiple groups of damping adjustment components share one adjustment shaft.

[0013] As a further improvement of the present invention, a driving sprocket coaxially and fixedly connected to the wire rope accommodating drum is provided on one side of the wire rope accommodating drum.

[0014] Compared with the existing technology, this wire rope damping rope releasing device does not require additional power when performing rope releasing operations, and can rely on mechanical structure to achieve damping rope releasing. According to the amount of rope released, the forward or reverse rotation of the force regulating wheel is adjusted to adjust the damping force applied by the damping adjustment mechanism on the wire rope accommodating drum to avoid slipping and sliding.

[0019] The present invention will be further described below with reference to the accompanying drawings (hereinafter described with the direction pointing to the inside of the supporting inner tube 2-3 as the inner direction and the direction pointing to the outside of the supporting inner tube 2-3 as the outer direction).

[0020] like Figure 1 As shown, the wire rope damping release device includes a wire rope accommodating drum 3 which is installed between the left support frame 1 and the right support frame 5 in a rolling manner.

[0021] like Figure 2 、 Figure 3As shown, the wire rope accommodating drum 3 is also provided with a damping application adjustment mechanism 2, which includes an adjustment shaft 2-1, a force adjustment wheel 2-2 and a damping adjustment assembly. The damping adjustment assembly includes a support inner cylinder 2-3, a compression spring 2-4, a movable disc 2-5, a brake friction plate 2-6, a static disc 2-7 and a support member 2-8. The support inner cylinder 2-3 is coaxially fixedly arranged in the wire rope accommodating drum 3, and the adjustment shaft 2-1 is coaxially connected and mounted on the support inner cylinder 2-3 through two support members 2-8. The force adjustment wheel 2-2 is connected to the axial end of the adjustment shaft 2-1 and is located inside the support inner cylinder 2-3. The static disc 2-7, brake friction pad 2-6, dynamic disc 2-5 and compression spring 2-4 are sequentially sleeved on the adjusting shaft 2-1 from outside to inside. The dynamic disc 2-5 is radially positioned and axially slidable relative to the supporting inner tube 2-3. The static disc 2-7 is positioned relative to the left support frame 1 or the right support frame 5. One end of the compression spring 2-4 is connected to the dynamic disc 2-5 through a rotating disc, and the other end is connected to the adjusting shaft 2-1. By rotating the force adjusting wheel 2-2, the adjusting shaft 2-1 can drive the compression spring 2-4 to move along the axial direction of the adjusting shaft 2-1, and then the dynamic disc 2-5 can be moved close to or away from the brake friction pad 2-6.

[0022] When using the present wire rope damping release device for the rope release operation, no additional power is required, and the damping applied to the wire rope receiving drum 3 can be adjusted by the damping application adjustment mechanism 2 according to the amount of rope released to avoid slipping and sliding. Specifically, for example, the forward rotation of the force regulating wheel 2-2 can cause the movable plate 2-5 to move axially in the direction of the static plate 2-7. Figure 2 、 Figure 3 As shown, during the rotation of the wire rope accommodating drum 3 and the rope releasing process, the supporting inner cylinder 2-3 and the movable disc 2-5 are driven to rotate synchronously. When the force regulating wheel 2-2 rotates in the forward direction, the compression spring 2-4 is driven to move in the direction of the static disc 2-7, and then the compression spring 2-4 pushes the movable disc 2-5 in the direction of the static disc 2-7 and squeezes the brake friction plate 2-6. The positive pressure between the movable disc 2-5, the brake friction plate 2-6 and the static disc 2-7 increases, and the friction resistance of the movable disc 2-5 that rotates synchronously with the wire rope accommodating drum 3 increases synchronously, thereby increasing the rotational damping of the wire rope accommodating drum 3; similarly, when the force regulating wheel 2-2 rotates in the reverse direction, the positive pressure between the movable disc 2-5, the brake friction plate 2-6 and the static disc 2-7 decreases, thereby reducing the rotational damping of the wire rope accommodating drum 3.

[0023] Example 1: As an implementation method of applying the damping force of the present invention, the damping force is applied by controlling the adjustment shaft 2-1 to move along its axial direction. Specifically, Figure 2As shown, the adjusting shaft 2-1 is radially positioned and axially slidable relative to the left support frame 1 or the right support frame 5, the force adjusting wheel 2-2 is threadedly connected to the axial end of the adjusting shaft 2-1, and the end face of the force adjusting wheel 2-2 is against the left support frame 1 or the right support frame 5, the static plate 2-7 is axially slidable relative to the adjusting shaft 2-1, and the other end of the compression spring 2-4 is fixedly connected to the adjusting shaft 2-1 through the positioning plate. When the force regulating wheel 2-2, whose end face rests on the left support frame 1 or the right support frame 5, rotates forward, the adjusting shaft 2-1 moves axially relative to the force regulating wheel 2-2 in the direction of the stator disc 2-7, thereby driving the compression spring 2-4 to move in the direction of the stator disc 2-7. This, in turn, pushes the dynamic disc 2-5 in the direction of the stator disc 2-7 through the compression spring 2-4 and squeezes the brake friction pad 2-6. Similarly, when the force regulating wheel 2-2 rotates in the reverse direction, the adjusting shaft 2-1 moves axially relative to the force regulating wheel 2-2 in the direction opposite to the direction of the stator disc 2-7, thereby driving the compression spring 2-4 to move in the direction opposite to the direction of the stator disc 2-7. In order to increase the upper limit of the rotational damping of the wire rope receiving drum 3, the damping adjustment components can be arranged in multiple groups coaxially in series, and the multiple groups of damping adjustment components share one adjusting shaft 2-1.

[0024] Example 2: As another embodiment of the damping force application of the present invention, the damping force is applied by controlling the adjustment shaft 2-1 to rotate along its axis. Specifically, Figure 3As shown, the adjusting shaft 2-1 is axially positioned relative to the left support frame 1 or the right support frame 5, and the adjusting shaft 2-1 is rollingly mounted with the support member 2-8, the force adjusting wheel 2-2 is fixedly connected to the axial end of the adjusting shaft 2-1, and the adjusting shaft 2-1 is provided with a clamping nut 2-9 threadedly connected to the adjusting shaft 2-1 on the axial section inside the supporting inner tube 2-3, and the clamping nut 2-9 is radially positioned relative to the left support frame 1 or the right support frame 5, and the other end of the compression spring 2-4 is mounted and connected to the adjusting shaft 2-1 through the clamping nut 2-9. When the force regulating wheel 2-2 rotates forward, the regulating shaft 2-1 rotates forward along its axis and drives the clamping nut 2-9 to move axially in the direction of the static disc 2-7 through the thread, thereby driving the compression spring 2-4 to move in the direction of the static disc 2-7, thereby pushing the dynamic disc 2-5 to move in the direction of the static disc 2-7 through the compression spring 2-4 and squeezing the brake friction pad 2-6; similarly, when the force regulating wheel 2-2 rotates reversely, the regulating shaft 2-1 rotates reversely along its axis and drives the clamping nut 2-9 to move axially in the opposite direction of the static disc 2-7 through the thread, thereby driving the compression spring 2-4 to move in the opposite direction of the static disc 2-7. In order to increase the upper limit of the rotational damping of the wire rope accommodating drum 3, a bidirectional thread can be set on the shaft section of the adjusting shaft 2-1 located inside the supporting inner cylinder 2-3, which is symmetrically arranged with respect to the supporting inner cylinder 2-3, and the static disc 2-7, brake friction plate 2-6, movable disc 2-5, compression spring 2-4 and clamping nut 2-9 are all symmetrically arranged with respect to the supporting inner cylinder 2-3, so that when the adjusting shaft 2-1 rotates along its central axis, it can drive the two clamping nuts 2-9 to move synchronously along the axial direction of the adjusting shaft 2-1, and generate opposite movement or opposite movement between the two clamping nuts 2-9, thereby achieving the doubling effect of the damping force applied.

[0025] In order to realize the rope-collecting operation, as a further improvement scheme of the present invention, a driving sprocket 4 is provided on one side of the wire rope accommodating drum 3 which is coaxially fixed thereto. During the rope-collecting operation, the wire rope accommodating drum 3 can be connected to the driving motor chain through the driving sprocket 4, and the rotational damping of the wire rope accommodating drum 3 is adjusted to a zero damping state through the force adjusting wheel 2-2, that is, the compression spring 2-4 is completely released so that the positive pressure between the movable disc 2-5, the brake friction plate 2-6 and the static disc 2-7 is zero, and the wire rope accommodating drum 3 can be driven by the driving motor to rotate for the rope-collecting operation.

[0026] Since the trapezoidal thread connection has good self-locking performance, as a preferred solution of the present invention, the thread matching is all trapezoidal thread matching connection.

[0027] Since the disc spring has the effect of achieving low stroke and high compensation force, as a preferred embodiment of the present invention, the compression spring 2-4 is a disc spring structure.
