Description

Technical Field

[0001] This invention relates to the field of wire rope winding equipment technology, specifically to an automatic wire rope pretensioning winding device. Background Technology

[0002] Wire rope is a type of rope made of multiple high-strength steel wires twisted together. It is widely used in various engineering fields, such as lifting equipment, mining operations, construction, and marine engineering. Wire rope plays a crucial role in these applications due to its excellent tensile strength, wear resistance, and high load-bearing capacity. However, wire rope requires regular maintenance and storage during use to ensure its long-term performance stability and safety.

[0003] Traditional wire rope winding methods typically rely on manual operation or simple mechanical equipment. This is not only time-consuming and labor-intensive, but also makes it difficult to ensure the uniformity and tightness of the winding, easily leading to loosening of the wire rope during the winding process. Loose wire rope is not only prone to slipping or uneven winding, but may also cause friction between the wires, increasing wear and shortening the service life of the wire rope. Furthermore, due to the loose winding, the wire rope may become knotted or break during use, thus affecting the safety and efficiency of engineering operations.

[0004] To address these issues, wire rope winding devices have emerged on the market. These devices aim to automate the winding of wire ropes through mechanization, ensuring orderly arrangement and tight winding, thereby improving work efficiency and safety, and effectively extending the service life of the wire ropes. However, existing wire rope winding devices still have some shortcomings in practical use.

[0005] Currently, most wire rope winding devices suffer from slack during the winding process because the wire rope cannot be kept taut at all times. This slack not only makes the wire rope prone to loosening, increasing wear between the wire ropes, but also leads to uneven winding, affecting the normal operation of the winding device. Furthermore, the slack in the wire rope may generate irregular force distribution during winding, further exacerbating wire rope wear. Therefore, achieving a tighter and more uniform winding effect, reducing wear, extending service life, and improving the overall operational stability of the equipment are technical problems that those skilled in the art are addressing. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automatic wire rope pretensioning winding device, which solves the problem that in some existing wire rope winding devices, the wire rope is not under tension, resulting in loose winding, easy loosening, increased wear between wire ropes, and affecting the normal use of the winding device.

[0007] This invention provides an automatic wire rope pretensioning winding device, comprising a frame, a base plate installed at the bottom of the frame, a winding wheel rotatably connected to the inner wall of the frame, an adjustment device on one side of the frame, the adjustment device including a stabilizing frame fixedly connected to the frame, an adjustment plate rotatably connected to the stabilizing frame, a sleeve block slidably connected to the stabilizing frame, a guide rod fixedly connected to the sleeve block, a sliding sleeve slidably connected to the guide rod, a positioning frame fixedly connected to one side of the sliding sleeve, a positioning seat fixedly connected to the lower side of the positioning frame, an end of the adjustment plate away from the stabilizing frame rotatably connected to the positioning seat, a first base fixedly connected to the side of the frame near the stabilizing frame, a cylinder rotatably connected to the inner wall of the first base, a second base fixedly connected to the side of the adjustment plate near the frame, the output end of the cylinder rotating with the inner wall of the second base, and an auxiliary device and a driving device provided on the surface of the frame.

[0008] Preferably, there are two of each of the stabilizer, the sleeve, the guide rod, and the sliding sleeve, and the two stabilizers, sleeves, guide rods, and sliding sleeves are arranged symmetrically.

[0009] Preferably, the inner wall of the positioning frame is rotatably connected to guide rollers, and there are two guide rollers, which are arranged in a mirror image.

[0010] Preferably, a pad is fixedly connected to the lower side of the stabilizer, and the pad has a circular cross-section.

[0011] Preferably, a stop block is fixedly connected to the upper end of the guide rod, and the edge of the stop block is rounded.

[0012] Preferably, the auxiliary device includes a protective plate, which is fixedly connected to the upper surface of the frame. A shaft is fixedly connected to both sides of the protective plate, and a stabilizing rod is rotatably connected to the shaft. A pressure rod is fixedly connected to the end of the stabilizing rod away from the protective plate.

[0013] Furthermore, a handle is fixedly connected to the surface of the pressure rod, and the stabilizing rod is arc-shaped.

[0014] Furthermore, a torsion spring is sleeved on the shaft, and a protrusion is fixedly connected to the end of the shaft away from the protective plate. The two ends of the torsion spring are respectively fixedly connected to the protective plate and the protrusion.

[0015] Preferably, the driving device includes a motor located on one side of the frame, a control wheel fixedly connected to the driving end of the motor, a transmission wheel fixedly connected to the shaft of the winding wheel, and a belt drivingly connecting the control wheel and the transmission wheel.

[0016] Preferably, a mounting bracket is fixedly connected to the side of the frame near the motor, and the motor is mounted on the mounting bracket.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides an automatic wire rope pretensioning winding device. During use, when the cylinder extends or retracts, its output end pushes the second base, causing the adjusting plate to rotate around the stabilizing frame. The rotation of the adjusting plate drives the positioning seat to move, thereby causing the sliding sleeve to slide on the guide rod. Two guide rollers within the positioning frame guide the wire rope. By adjusting the position of the sliding sleeve, the path and tension of the wire rope can be changed. The two stabilizing frames, the sleeve block, the guide rod, and the sliding sleeve are symmetrically arranged to ensure the stability of the adjustment process. The pad block and the stop block serve to stabilize and limit movement, respectively. The protective plate in the auxiliary device is fixed to the frame. The stabilizer bar on the shaft is connected to the pressure bar. Under normal conditions, the torsion spring keeps the pressure bar in a certain position. When auxiliary operation is required, the pressure bar can be operated by the handle, and the stabilizer bar rotates around the shaft to assist in positioning or adjusting the wire rope. The drive device is powered by a motor, which drives the winding wheel to rotate through belt transmission, realizing the automatic winding of the wire rope. This solution has a clever structure, which makes it easy to adjust the tension of the wire rope during winding, ensuring that the equipment can stably wind the wire rope, reducing friction between the wire ropes, reducing economic losses for users, and ensuring the stable use of the equipment.

Detailed Implementation

[0028] The embodiments described below are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] See Figures 1-7This embodiment provides an automatic wire rope pretensioning winding device, including a frame 1. A foot 2 is installed on the lower surface of the frame 1. A winding wheel 3 is rotatably connected to the inner wall of the frame 1. An adjustment device 4 is provided on one side surface of the frame 1. The adjustment device 4 includes a stabilizing frame 41 connected to the surface of the frame 1. An adjusting plate 43 is rotatably connected to the surface of the stabilizing frame 41. A sleeve block 413 is slidably connected to the stabilizing frame 41. A guide rod 44 is connected to the upper surface of the sleeve block 413. A sliding sleeve 45 is slidably connected to the guide rod 44. A positioning frame 47 is provided on one side of the sliding sleeve 45. A positioning seat 49 is connected to the lower surface of the positioning frame 47. The end of the adjusting plate 43 away from the stabilizing frame 41 is rotatably connected to the surface of the positioning seat 49. A first base 410 is fixedly connected to the side of the stabilizer 41. A cylinder 411 is rotatably connected to the inner wall of the first base 410. A second base 412 is fixedly connected to the side of the adjusting plate 43 near the frame 1. The output end of the cylinder 411 rotates with the inner wall of the second base 412. An auxiliary device 5 is provided on the surface of the frame 1, and a driving device 6 is provided on the surface of the frame 1. The adjusting plate 43 is pushed by the cylinder 411, which in turn drives the sliding sleeve 45 to slide on the guide rod 44. The pretension of the wire rope can be precisely adjusted to meet the winding requirements of wire ropes of different specifications. This solution has a clever structure, which makes it easy to adjust the tightness when winding the wire rope, ensuring that the equipment can stably wind the wire rope, reducing friction between the wire ropes, reducing the economic losses of the user, and ensuring the stable use of the equipment.

[0030] Specifically, there are two of each of the following: the stabilizing frame 41, the sleeve block 413, the guide rod 44, and the sliding sleeve 45. These components are symmetrically arranged. This effectively improves the stability and working accuracy of the equipment. The symmetrical arrangement not only ensures a uniform force distribution on the wire rope during winding but also reduces wire rope deviation and slackness, avoiding winding quality problems caused by uneven tension. Furthermore, it optimizes the wire rope's guide path, making it smoother during winding, thereby reducing friction and wear and extending the service life of the wire rope and the equipment. Simultaneously, it simplifies the adjustment and maintenance process, improving operational convenience and stability.

[0031] In this embodiment, guide rollers 48 are rotatably connected to the inner wall of the positioning frame 47. There are two guide rollers 48, which are mirror images of each other. The two guide rollers 48 within the positioning frame 47 ensure smooth movement of the wire rope during adjustment, preventing damage. It should be noted that a high-precision tension sensor is installed at or near the axis of the guide rollers 48. Since the two guide rollers 48 within the positioning frame 47 guide the wire rope and are in direct contact with it during adjustment, installing the high-precision tension sensor at or near the axis of the guide rollers 48 allows for direct measurement of the tension of the wire rope as it passes through the guide rollers, thus ensuring the accuracy and real-time nature of the measurement.

[0032] In order to achieve precise control and adaptive adjustment of wire rope tension, this application also provides a PLC processor. The high-precision tension sensor is connected to the PLC processor. The high-precision tension sensor continuously monitors the tension value of the wire rope during the winding process and converts these monitored analog signals into digital signals. The PLC processor receives the digital signals from the high-precision tension sensor and performs data preprocessing, including filtering and noise reduction (such as using a Kalman filter or median filter to remove random noise), data smoothing (such as moving average or exponential smoothing), and outlier detection (identifying and removing abnormal data points through statistical methods or threshold-based methods). Then the PLC processor performs state analysis on the real-time tension, including: (1) Tension range judgment: comparing the real-time tension value with the preset tension range (including minimum safe tension, target tension, and maximum allowable tension) to determine whether the current tension state is within the normal range. (2) Trend prediction: using time series analysis technology (such as ARIMA model and / or LSTM neural network) to predict the tension change in the future short period of time so as to make adjustments in advance. (3) Dynamic characteristic analysis: Considering the influence of winding speed, wire rope material, and ambient temperature on tension, these dynamic relationships are learned through machine learning models (such as support vector machines, random forests) or deep learning models (such as convolutional neural networks CNN for image-assisted analysis) to improve prediction accuracy. Then, based on the real-time tension state and prediction results, control strategy decisions are made, including: (1) Feedback control: If the tension deviates from the preset range, the system immediately starts the feedback control mechanism, such as adjusting the speed of motor 62 (through a PID controller or a more advanced fuzzy logic / neural network controller) to quickly correct the tension deviation. (2) Feedforward control: Using prediction information, the control parameters are actively adjusted before the tension deviates, and the speed of motor 62 is changed in advance to reduce the amplitude and frequency of tension fluctuations. (3) Adaptive adjustment: Based on historical data and current control effect, the parameters in the control strategy (such as the gain coefficient of the PID controller) are continuously optimized to improve the system's adaptive capability and control accuracy. At the same time, when a tension value that deviates significantly from the preset range is detected, a safety alarm is immediately triggered, and emergency shutdown measures may be taken to prevent accidents. It should be noted that in this application, the PLC processor stores all key data (including real-time tension values, control parameters, adjustment records, etc.) in a database for subsequent analysis and troubleshooting. Furthermore, the PLC processor periodically generates tension control reports, including tension distribution statistics, abnormal event records, efficiency analysis, etc., providing corresponding support for production management and decision-making.

[0033] Specifically, a stop block 46 is fixedly connected to the upper end of the guide rod 44. The edge of the stop block 46 is rounded. In actual use, when the cylinder 411 extends or retracts, its output end pushes the second base 412, thereby causing the adjusting plate 43 to rotate around the stabilizer 41. This rotation causes the positioning seat 49 on the adjusting plate 43 to move, thus allowing the sliding sleeve 45 to slide smoothly along the guide rod 44. The two guide rollers 48 equipped in the positioning frame 47 are specifically used to precisely guide the wire rope, ensuring that it maintains a stable path and tension during adjustment. Specifically, by precisely adjusting the position of the sliding sleeve 45, the path and tension of the wire rope can be flexibly changed. This adjustment mechanism allows the wire rope to be precisely pre-tensioned according to actual needs, thereby adapting to winding operations of different specifications or requirements. To ensure the stability of the entire adjustment process, the present invention adopts a symmetrical design. The two stabilizers 41, sleeve 413, guide rod 44, and sliding sleeve 45 are all arranged symmetrically. This design effectively ensures uniform force distribution on each component during adjustment, avoiding offset or instability caused by uneven force. Furthermore, a pad 42 with a circular cross-section is fixedly connected to the lower surface of the stabilizer 41. The circular cross-section of the pad 42 effectively disperses the pressure applied by the stabilizer 41 to the surface of the frame 1, reducing local pressure concentration and thus improving the stability of the entire device. Simultaneously, the circular structure allows for more uniform contact with the surface of the frame 1, reducing vibration or tilting caused by uneven contact area and ensuring the stability of the stabilizer during operation. The rounded edges of the stop 46 serve a dual function of limiting and guiding, preventing excessive movement of the wire rope during adjustment and reducing friction with the stop, ensuring smooth operation of the wire rope.

[0034] In this invention, the auxiliary device 5 includes a protective plate 51 connected to the frame 1. Shafts 55 are connected to both sides of the protective plate 51, and a stabilizing rod 52 is rotatably connected to each shaft 55. A pressure rod 53 is securely fixed to the end of the stabilizing rod 52 away from the protective plate 51. To further enhance operational convenience, a handle 54 is also fixedly connected to the surface of the pressure rod 53, allowing for quick adjustments by the operator when needed. The stabilizing rod 52 is designed in an arc shape, fully considering mechanical stability and operational flexibility. This structure allows for better alignment with the wire rope during rotation, avoiding excessive pressure or damage to the wire rope. The handle 54 not only increases operational comfort but also significantly improves the convenience and efficiency of adjustments. Under normal operating conditions, the protective plate 51 is securely mounted on the frame 1, ensuring the overall stability of the equipment. The stabilizing rod 52 on the shaft 55, through the action of a torsion spring 56, holds the pressure rod 53 in a preset position, ensuring the entire device remains stable. When auxiliary positioning or adjustment of the wire rope is required, the operator can flexibly operate the pressure bar 53 using handle 54. At this time, the stabilizer bar 52 will smoothly rotate around the shaft 55, thereby providing precise auxiliary positioning or adjustment of the wire rope. This design ensures that during operation, whether positioning the wire rope or adjusting its path, the operator can achieve precise control through simple operation. The linkage design of the pressure bar 53 and the stabilizer bar 52 greatly improves the working efficiency of the equipment, and due to the arc-shaped design of the stabilizer bar 52, the wire rope experiences more uniform stress during adjustment, reducing the possibility of equipment wear and malfunction.

[0035] In this embodiment, a torsion spring 56 is fitted onto the shaft 55, providing crucial elastic support for the entire device. Specifically, a protrusion 57 is fixedly connected to the end of the shaft 55 furthest from the protective plate 51. The two ends of the torsion spring 56 are tightly fixed to the surfaces of the protective plate 51 and the protrusion 57, respectively, enabling the torsion spring 56 to provide a stable elastic restoring force to the pressure rod 53 during operation. This elastic restoring force not only enhances operational flexibility but also allows the pressure rod 53 to quickly return to its initial position during use, ensuring operational efficiency and continuity. Whether adjusting the wire rope or after auxiliary positioning, the torsion spring 56 effectively maintains the stability of the pressure rod 53, reducing the possibility of human error. Furthermore, it possesses strong adaptability, automatically adjusting the restoring force of the pressure rod 53 according to different working conditions, ensuring operational smoothness and accuracy.

[0036] In this embodiment, the drive device 6 includes a motor 62 located on one side of the frame 1. The drive end of the motor 62 is connected to a transmission wheel 64 fixedly connected to the shaft of the winding wheel 3 via a control wheel 63. The control wheel 63 and the transmission wheel 64 are connected by a belt 65. When the motor 62 starts, the belt 65 transmits the power of the motor to the winding wheel 3, driving it to rotate smoothly, thereby realizing the automatic winding function of the wire rope. This not only simplifies the operation process but also greatly improves production efficiency.

[0037] Furthermore, a mounting bracket 61 is precisely fixedly connected to the side of the frame 1 near the motor 62, and the motor 62 is securely mounted on the mounting bracket 61. The design of the mounting bracket 61 fully considers structural stability, ensuring that the motor 62 will not shift or vibrate during operation, thereby maintaining the smooth and reliable operation of the entire drive system. Therefore, the drive unit 6 can not only effectively drive the rotation of the winding wheel 3 to achieve automatic winding of the wire rope, but also ensure the stability and efficiency of the entire operation process. The combination of the motor 62 and the mounting bracket 61 allows the drive system to maintain optimal performance under different working environments, providing operators with a more convenient and reliable operating experience.

[0038] It should be noted that, in use, when the cylinder 411 extends or retracts, its output end pushes the second base 412, causing the adjusting plate 43 to rotate around the stabilizer 41. The rotation of the adjusting plate 43 drives the positioning seat 49 to move, thereby causing the sliding sleeve 45 to slide on the guide rod 44. The two guide rollers 48 inside the positioning frame 47 are used to guide the wire rope. By adjusting the position of the sliding sleeve 45, the path and tension of the wire rope can be changed. The two stabilizers 41, the sleeve block 413, the guide rod 44, and the sliding sleeve 45 are symmetrically arranged to ensure the stability of the adjustment process. The pad block 42 and the stop block 46 play the roles of stabilization and limiting, respectively. The protective device in the auxiliary device 5... Plate 51 is fixed on frame 1. The stabilizing rod 52 on shaft 55 is connected to pressure rod 53. Under normal conditions, torsion spring 56 keeps pressure rod 53 in a certain position. When auxiliary operation is required, pressure rod 53 can be operated through handle 54, and stabilizing rod 52 rotates around shaft 55 to assist in positioning or adjusting wire rope. Drive device 6 is powered by motor 62 and driven by belt 65, so that motor 62 drives winding wheel 3 to rotate, realizing automatic winding of wire rope. This solution has a clever structure, which makes it easy to adjust the tightness of wire rope when winding, ensuring stable winding of wire rope by equipment, reducing friction between wire ropes, reducing economic losses for users, and ensuring stable use of equipment.

[0039] This invention also features precise control and adaptive adjustment of wire rope tension. The system monitors wire rope tension changes in real time through a tension sensor in the intelligent control system and fine-tunes preset tension parameters to ensure the wire rope maintains optimal tension under various working conditions. Furthermore, the system can automatically adjust the tension control strategy based on the wire rope's diameter, material, and operating environment, further improving the equipment's versatility and operational quality. This precise tension control and adaptive adjustment effectively prevents wire rope damage caused by improper tension, while also enhancing the safety and reliability of the entire operation.

[0040] The above-disclosed embodiments are merely some preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
