Description

Technical Field

[0001] This utility model relates to the technical field of mine hoisting systems, specifically to a tail rope anti-twisting device for mine hoisting systems. Background Technology

[0002] Tail rope anti-knotting is typically used in industrial high-altitude operations, fire rescue, mountaineering and exploration, mining and other fields to prevent the "tail rope" used to connect to the main rope or safety belt from twisting or tangling, thereby ensuring operational safety and efficiency.

[0003] For example, patent application number 202421940988.5 published on the China Patent Network, entitled "Anti-Twisting Device for Tail Rope," includes a mounting frame. AI cameras are mounted at both ends of the mounting frame, and load-bearing horizontal plates are connected to both sides of the mounting frame. A connecting seat is connected to the top of the load-bearing horizontal plates, and a drive motor is mounted at one end of the connecting seat. A bidirectional threaded rod is connected to the output end of the drive motor. Two threaded connecting blocks are threadedly connected to the outer wall of the bidirectional threaded rod. A guide rod is provided inside the connecting seat, and a connecting plate is connected to each end of the two threaded connecting blocks. This invention uses a drive motor to rotate the bidirectional threaded rod clockwise, causing the two threaded connecting blocks to move in opposite directions along the guide rod. The connecting plates at the ends of the two threaded connecting blocks then drive the tail rope guide wheels to move. As the two threaded connecting blocks move in opposite directions, the two tail rope guide wheels spread the ends of the tail rope to prevent kinking.

[0004] However, the existing support method is relatively simple, mainly relying on overlapping for connection. During the movement of the crane, the tail rope is prone to shaking, causing the tail rope to lose contact with the guide wheel, which seriously affects the support effect. Moreover, the screw rotation process is slow, and a lot of time is required when emergency adjustment is needed.

[0005] Therefore, it is necessary to redesign and modify the anti-twist device for the tail rope of the mine hoisting system. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a tail rope anti-twisting device for mine hoisting systems, which has the advantages of improving adjustment efficiency and stability. It solves the problems of existing devices having a relatively simple support method, mainly relying on overlapping for connection, which makes the tail rope prone to swaying during crane movement, causing the tail rope to lose contact with the guide wheel, seriously affecting the support effect. Moreover, the screw rotation process is slow, requiring a lot of time when emergency adjustments are needed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tail rope anti-twist device for a mine hoisting system, including a suspension tail rope; A connecting frame is provided on the outer side of the suspension tail rope, and brackets are provided on both sides of the top of the connecting frame. The brackets are set as the two sides of the suspension tail rope. Push rods located on both sides of the suspension tail rope are fixedly connected to the inner side of the brackets. The outer surface of the push rods can contact the surface of the suspension tail rope. An adjustment structure is provided on the surface of the connecting frame, which can push the two brackets to move towards each other.

[0008] As a preferred embodiment of this utility model, the adjustment structure includes a connecting block fixedly connected to the surface of the bracket, a crank movably connected to the surface of the connecting block via a pin, a transmission plate mounted on the bottom of the connecting frame via a driving component, and the side of the crank away from the connecting block extending to the outside of the transmission plate and movably connected to the transmission plate via a pin.

[0009] In a preferred embodiment of this invention, the driving component is an electric telescopic rod fixedly connected to the top of the connecting frame. The output end of the electric telescopic rod passes through the connecting frame and extends to the bottom of the connecting frame. The output end of the electric telescopic rod is fixedly connected to the top of the transmission plate.

[0010] In a preferred embodiment of this utility model, upright plates are fixedly connected to both the left and right sides of the connecting frame, and guide rods are fixedly connected to the inner side of the upright plates. A limiting plate is fixedly connected to the surface of the bracket, and the limiting plate is sleeved on the surface of the guide rod and slidably connected to the guide rod.

[0011] In a preferred embodiment of this invention, the bottom of the transmission plate is movably connected to a support wheel via a pin, and the outer surface of the support wheel is in contact with the surface of the suspension tail rope.

[0012] As a preferred embodiment of this utility model, a column located outside the electric telescopic rod is fixedly connected to the top of the connecting frame, and a mounting bracket is fixedly connected to the top of the column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets up a connecting frame that surrounds the tail rope, and configures brackets and push rods on both sides that can be driven to move in opposite directions by an adjustable structure. This achieves active, adjustable and balanced clamping or support for the tail rope, fundamentally solving the problems of easy loosening and single support in traditional splicing methods, and effectively preventing the tail rope from shaking and twisting.

[0014] 2. This utility model uses a linkage-type adjustment structure consisting of a connecting block, a crank, and a transmission plate to efficiently convert the linear motion of the drive component into synchronous opposite or opposite motion of the two supports. The transmission is rapid and the symmetry of the forces acting on both sides of the tail rope is guaranteed.

[0015] 3. By using an electric telescopic rod as the driving component, this utility model realizes the electric drive and rapid response of the device, enabling remote control or automatic adjustment, which significantly improves the adjustment speed and convenience.

[0016] 4. This utility model provides precise guidance and limitation for the movement of the support by setting a vertical plate and a guide rod on the connecting frame and making the limiting plate on the support slide with the guide rod, ensuring that the support can only perform horizontal linear movement and preventing it from deflecting or getting stuck during movement.

[0017] 5. This utility model adds a movable support wheel to the bottom of the transmission plate, so that it can contact and support the tail rope from below when the transmission plate moves down. Together with the push rods on both sides, it forms a three-point support structure, thereby providing more comprehensive constraint on the tail rope.

[0018] 6. By setting up columns and mounting frames, this utility model provides a stable mounting point for the entire anti-kink device that is higher than the connecting frame and drive components, making it easy to fix the entire device to the support structure above the mine, thus ensuring the overall stability of the device during operation.

A bracket 3 is provided on both sides of the top of the connecting frame 2. The bracket 3 is set as the two sides of the suspension tail rope 1. The inner side of the bracket 3 is fixedly connected to the push rod 4 located on both sides of the suspension tail rope 1. The outer surface of the push rod 4 can contact the surface of the suspension tail rope 1. An adjustment structure is provided on the surface of the connecting frame 2. The adjustment structure can push the two brackets 3 to move towards each other.

[0023] refer to Figure 4 The adjustment structure includes a connecting block 5 fixedly connected to the surface of the bracket 3. A crank 6 is movably connected to the surface of the connecting block 5 via a pin. A transmission plate 7 is mounted on the bottom of the connecting frame 2 via a drive component. The side of the crank 6 away from the connecting block 5 extends to the outside of the transmission plate 7 and is movably connected to the transmission plate 7 via a pin.

[0024] As a technical optimization of this utility model, the linear motion of the driving component is efficiently converted into synchronous opposite or opposite motion of the two supports 3 through the linkage adjustment structure composed of connecting block 5, crank 6 and transmission plate 7. The transmission is fast and the symmetry of the force acting on both sides of the tail rope is guaranteed.

[0025] refer to Figure 2 The driving component is an electric telescopic rod 8 fixedly connected to the top of the connecting frame 2. The output end of the electric telescopic rod 8 passes through the connecting frame 2 and extends to the bottom of the connecting frame 2. The output end of the electric telescopic rod 8 is fixedly connected to the top of the transmission plate 7.

[0026] As a technical optimization of this utility model, by using an electric telescopic rod 8 as a driving component, the device is electrically driven and responds quickly, enabling remote control or automatic adjustment, which significantly improves the adjustment speed and convenience.

[0027] refer to Figure 1 The left and right sides of the connecting frame 2 are fixedly connected to the upright plate 9, the inner side of the upright plate 9 is fixedly connected to the guide rod 10, and the surface of the bracket 3 is fixedly connected to the limiting plate 11. The limiting plate 11 is sleeved on the surface of the guide rod 10 and is slidably connected to the guide rod 10.

[0028] As a technical optimization of this utility model, by setting a vertical plate 9 and a guide rod 10 on the connecting frame 2, and making the limiting plate 11 on the bracket 3 form a sliding connection with the guide rod 10, the movement of the bracket 3 is provided with precise guidance and limitation, ensuring that the bracket 3 can only perform horizontal linear movement and preventing it from deflecting or getting stuck during the movement.

[0029] refer to Figure 2 The bottom of the transmission plate 7 is movably connected to the support wheel 12 via a pin, and the outer surface of the support wheel 12 is in contact with the surface of the suspension tail rope 1.

[0030] As a technical optimization of this utility model, a movable support wheel 12 is added to the bottom of the transmission plate 7, so that it can contact and support the tail rope from below when the transmission plate 7 moves down, forming a three-point support structure together with the push rods 4 on both sides, thereby forming a more comprehensive constraint on the tail rope.

[0031] refer to Figure 1 The top of the connecting frame 2 is fixedly connected to a column 13 located outside the electric telescopic rod 8, and the top of the column 13 is fixedly connected to a mounting bracket 14.

[0032] As a technical optimization of this utility model, by setting up the column 13 and the mounting frame 14, a stable mounting point higher than the connecting frame 2 and the driving component is provided for the entire anti-kink device, which makes it easy to fix the device as a whole on the support structure above the mine, thus ensuring the overall stability of the device during operation.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to clamp the tail rope, the output end of the electric telescopic rod 8 extends downward, driving the transmission plate 7 fixed thereto to move downward synchronously. The movement of the transmission plate 7 causes the upper ends of the cranks 6 connected by pins on both sides to rotate downward. The cranks 6 then rotate around the hinge point between the middle part and the connecting block 5 on the bracket 3, thereby converting the vertical downward thrust into a horizontal inward thrust, pushing the left and right brackets 3 to move synchronously and smoothly towards the center along the guide rod 10. Finally, the push rod 4 on the inner side of the bracket 3 clamps the hanging tail rope 1 from both sides, while the support wheel 12 at the bottom of the transmission plate 7 supports the tail rope from below, forming a stable three-point constraint, effectively suppressing the swaying and twisting of the tail rope.

[0034] In summary, the tail rope anti-twisting device of this mine hoisting system, by setting up a connecting frame 2 that surrounds the tail rope and configuring brackets 3 and push rods 4 on both sides that can be driven to move in opposite directions by an adjustable structure, achieves active, adjustable and balanced clamping or support for the tail rope, fundamentally solving the problems of easy loosening and single support in traditional splicing methods, and effectively preventing tail rope swaying and twisting.
