Description

Technical Field

[0001] This invention relates to the field of cable and filament material handling technology, specifically a two-stage elastic buffer station cable assembly device. Background Technology

[0002] As a core force transmission component in hoisting, transportation, port loading and unloading, and construction machinery, the tension adjustment capability, shock absorption performance, and operational stability of cable assemblies directly affect the operating accuracy, safety, and service life of the equipment. With the increasing demands of modern industry for efficient and heavy-duty operations, cable assemblies need to withstand complex working conditions such as high-frequency load impacts and dynamic tension fluctuations over long periods of time.

[0003] In the prior art, patent document CN216863254U discloses a device for reducing the frictional resistance of component cables during tensioning. The device includes a chute plate, which is fixedly installed above the upper flange of an H-beam. The chute plate has an arc-shaped groove, and two vertical rollers are symmetrically installed on both sides of the groove. The rollers are mounted on the chute plate via a fixed shaft and can rotate around the fixed shaft. In application of this invention, during the tensioning process of the component cable, the arc-shaped groove on the chute plate provides a certain constraint force to prevent the component cable from shifting left or right. The rollers are symmetrically installed in the middle of the groove. When the component cable passes through, the frictional resistance drives the rollers to rotate, thereby converting the sliding friction of the component cable into rolling friction between the component cable and the rollers, reducing the frictional resistance during passage.

[0004] The above-mentioned technical solutions mainly focus on reducing the friction of the component cables during the tensioning process, but they do not adequately consider the buffering and shock absorption, dynamic tension adjustment, and improvement of the operational stability of the cable assembly under complex working conditions. When the equipment is under conditions of large load impact and frequent tension fluctuations for a long time, it is still difficult to effectively meet the requirements of the cable assembly for stable support, shock absorption and buffering, and rapid adjustment. Based on this, the present invention provides a two-stage elastic buffer station cable assembly to solve the problems mentioned in the background art. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a two-stage elastic buffer station cable assembly device, which solves the problems of poor buffering and shock absorption effect, lag in tension adjustment response, and insufficient operational stability of existing cable assembly devices.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A double-stage elastic buffer station cable assembly device includes a cable assembly base and a lifting seat. A base mounting cover is fixedly installed on the top of the cable assembly base. The lifting seat is installed inside the cable assembly base and has a lifting function. Two mounting columns are provided at the top of the lifting seat. A transverse mounting beam is fixedly provided between the two mounting columns. A cable wheel mounting seat is fixedly provided at the middle of the top of the transverse mounting beam. A rotatable cable wheel frame is provided at the middle of the cable wheel mounting seat. Two cable wheel discs are rotatably provided on the cable wheel frame. Cables are placed in the grooves of the discs of the two cable wheel discs.

[0007] The beneficial effects of adopting the above-mentioned further solutions are that the main body of the cable assembly base is integrally cast from high-strength alloy steel, which can effectively bear the weight of the lifting seat, cable, and load, and resist the impact and vibration during operation. The internal cavity of the base provides space for the installation and operation of the hydraulic power unit, hydraulic lifting column, and lifting seat. The lifting limit grooves on both side walls provide precise guidance for the lifting of the lifting seat, ensuring a stable and reliable lifting process. The base mounting cover is fixedly installed on the top of the cable assembly base to seal and protect the top of the cable assembly base, preventing dust and debris from entering the inner cavity of the base and affecting the operation of internal components. At the same time, it can enhance the structural strength of the top of the cable assembly base and prevent the top from deforming due to excessive force. The main body of the lifting seat adopts a downward-opening frame structure design and is welded from high-strength alloy steel, which has excellent load-bearing and deformation resistance performance. Its core function is to provide stable installation support for the mounting columns, transverse mounting beams, and cable sheave mounting seats. Simultaneously, through connection with the hydraulic lifting column, it achieves overall lifting, thereby driving the cable sheave frame and cable to lift synchronously, providing a structural foundation for cable tension adjustment. Two mounting columns are fixedly installed at the top of the lifting seat, providing fixed support at both ends of the transverse mounting beam to ensure its firm and stable installation; they also provide a fixed installation foundation for the telescopic rod, ensuring the stable operation of the elastic buffer mechanism. The transverse mounting beam is fixedly installed between the two mounting columns, providing central fixed support for the cable sheave mounting seat and also providing an installation foundation for the pressure detection plate, ensuring the installation stability of the cable sheave frame and pressure monitoring mechanism, and enabling coordinated operation of cable sheave operation and load monitoring. The cable sheave mounting seat is fixedly installed at the top center of the transverse mounting beam, providing a rotating installation foundation for the cable sheave frame, ensuring its flexible rotation to adapt to changes in cable running direction and preventing cable entanglement or jamming. To ensure smooth cable transmission, a rotatable sheave frame combined with a double sheave disc structure is used. When the cable is under stress, the adaptive rotation of the sheave frame achieves initial force balance on both sides. Simultaneously, the double sheave disc design increases the contact area between the cable and the sheaves, reducing local pressure, minimizing cable wear, and extending the device's lifespan. The sheave frame is rotatably positioned in the center of the sheave mounting base, providing a rotating mounting foundation for the two sheave discs and ensuring flexible rotation. Meanwhile, shock-absorbing telescopic columns fixed on both sides of the bottom provide a two-stage elastic buffer function, absorbing impact loads during cable operation and ensuring stable operation of the sheave mechanism. The sheave discs, rotatably mounted on the sheave frame, are made of high-strength, wear-resistant material. Through rolling cooperation with the cable, they guide and transmit the cable. The grooved structure prevents slippage and detachment of the cable during transmission, ensuring the smoothness and safety of the cable transmission. The symmetrical design of the two sheave discs enhances the stability of the cable transmission and improves load-bearing capacity.

[0008] The beneficial effects of this invention are: 1) This invention features a lifting device inside the cable assembly base. A hydraulic power unit raises and lowers the two cable pulleys, automatically controlling the cable tension. The pulley frame also rotates, allowing it to shift to either side when the forces on the two pulleys are uneven. A pressure detection disc at the bottom monitors the pressure on both pulleys, providing workers with better information on the cable pulley pressure. This assists the lifting device in regulating the raising and lowering of the pulleys. The entire device provides real-time and reliable tension compensation with high operational stability, achieving real-time automatic compensation of the cable assembly tension and preventing a decrease in positioning accuracy due to cable slack after prolonged use.

[0009] 2) By setting a limiting groove inside the cable assembly base and a limiting plate on the lifting seat, the limiting plate moves stably within the limiting groove during the lifting process, thereby ensuring that the lifting seat remains stable during the lifting process. This ensures that the entire cable assembly device remains stable and does not shake during the tension adjustment process.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the cable assembly base has an inner cavity, and both sides of the inner cavity have lifting and limiting grooves.

[0012] Furthermore, the cable assembly base is equipped with a hydraulic power unit and two hydraulic lifting columns inside. The tops of the two hydraulic lifting columns are fixedly connected to the inner top of the lifting seat. The lifting seat is a frame with an opening facing downwards. The lifting seat achieves lifting and lowering functions within the cable assembly base through the two hydraulic lifting columns.

[0013] Furthermore, two limiting plates are fixedly installed on both sides of the lifting seat, and the four limiting plates slide up and down in four corresponding lifting limiting grooves to achieve the lifting limiting and stabilizing function of the lifting seat.

[0014] Furthermore, a shock-absorbing telescopic column is fixedly installed on both sides of the bottom of the cable wheel frame, and a shock-absorbing pad is fixedly installed at the bottom of both shock-absorbing telescopic columns.

[0015] Furthermore, pressure detection plates are fixedly installed at the top of the transverse mounting beam at the corresponding positions on the top of the two shock-absorbing pads, and pressure detectors are connected to the bottom of the two pressure detection plates.

[0016] Furthermore, a rotating joint is installed at the bottom of the pressure detector. A bottom mounting seat is rotatably connected to the inner wall of the bottom of the rotating joint. A bottom fixing seat is fixedly connected to the bottom of the bottom mounting seat. A sliding block is fixedly connected to the bottom of the bottom fixing seat. A telescopic rod is provided on one side of the outer wall of the sliding block. The telescopic rod is fixed to one side of the mounting column. A push terminal is fixedly connected to the other side of the outer wall of the sliding block. The push terminal, the sliding block, and the telescopic rod are all slidably connected to the inner wall of the limiting groove frame. A limiting frame is fixedly connected to one end of the push terminal. A rotating arm is rotatably connected to the inner wall of the limiting frame. The end of the rotating arm away from the push terminal is located on the side of the cable wheel mounting seat. A spring pull rod is installed between the rotating arms.

[0017] The beneficial effects of adopting the above-mentioned further scheme are that the shock-absorbing telescopic columns are fixedly installed on both sides of the bottom of the cable wheel frame, and the shock-absorbing pads are fixedly installed at the bottom of the shock-absorbing telescopic columns. The two work together to form a two-stage elastic buffer structure. The first stage absorbs the impact load through the elastic expansion and contraction of the shock-absorbing telescopic columns, and the second stage further buffers the vibration through the elastic deformation of the shock-absorbing pads. This effectively absorbs the start-stop impact and load fluctuations during the operation of the cable, prevents the impact load from being transmitted to other components, ensures the overall stable operation of the device, and extends the service life of the equipment. The pressure detection plate is fixedly installed on the top of the transverse mounting beam, corresponding to the position of the shock-absorbing pads, and is made of high-strength pressure sensing material. The pressure detector is connected to the bottom of the pressure detection plate and has high-precision pressure detection and signal transmission functions. Its core function is to monitor the pressure signal transmitted by the shock-absorbing pads in real time. This pressure signal indirectly reflects the tension and operating load changes of the cable. The rotating joint is installed at the bottom end of the pressure detector, the mounting base is rotatably connected to the inner wall of the bottom end of the rotating joint, and the bottom fixed base is fixedly connected to the bottom end of the bottom mounting base. The three components work together to achieve flexible rotational connection between the pressure detector and the sliding block, ensuring that the pressure detector maintains a reasonable force angle during elastic adjustment. This prevents a decrease in pressure detection accuracy due to angle deviation and guarantees the accuracy of monitoring data. The sliding block is fixedly connected to the bottom of the bottom mounting base, and the telescopic rod is fixed to one side of the mounting column and connected to one side of the outer wall of the sliding block. The limiting slot provides sliding guidance for the sliding block, telescopic rod, and push terminal. The elastic extension and retraction of the telescopic rod drives the sliding block to slide flexibly along the limiting slot, realizing the elastic adjustment of the pressure monitoring mechanism. Combined with the shock-absorbing telescopic column, it further enhances the buffering performance of the device. At the same time, the limiting slot can restrict the sliding direction of the sliding block to prevent deviation and ensure the stability of elastic adjustment. The push terminal is fixedly connected to the other side of the outer wall of the sliding block, and the limiting frame is fixedly connected to one end of the push terminal. The rotating arm is rotatably connected to the inner wall of the limiting frame, and the spring pull rod is installed between the two rotating arms. The spring pull rod has excellent elastic performance. Its core function is to form an elastic linkage structure. When the sliding block slides, it drives the limit frame and rotating arm to rotate by pushing the terminal. The spring rod absorbs the vibration and impact during the adjustment process through its own elastic extension and contraction, further enhancing the dual-stage elastic buffering effect of the device. At the same time, this structure can limit the sliding stroke of the sliding block, avoid excessive sliding that could damage the components, and ensure the reliability of the elastic adjustment.

[0018] Furthermore, a controller is installed inside the base cavity of the cable assembly base. The controller contains a network communication module and is connected to two pressure detectors. Based on the detection values ​​of the two pressure detectors, the controller controls the hydraulic power unit to raise and lower the lifting seat, thereby controlling the tension of the cable on the two cable pulley frames. As the core control unit of the device, the controller can automatically determine whether the cable is slack and whether the force is balanced by analyzing the data transmitted by the pressure detectors. When the pressure value is lower than a preset threshold, the controller controls the hydraulic lifting column to extend and drive the cable pulley to rise and tighten the cable. When the pressure difference on both sides exceeds the preset range, the height of the lifting seat can be finely adjusted or adaptively adjusted by rotating the cable pulley frame to ensure balanced force on the cable. The network communication module can upload the operating data and pressure parameters to the remote monitoring platform in real time, which is convenient for remote monitoring and fault warning by the staff, and realizes intelligent control.

[0019] Furthermore, a base is fixedly installed at the bottom of the cable assembly base, which secures the entire device in place.

[0020] The beneficial effects of adopting the above-mentioned further solutions are that the base provides a stable installation foundation for the entire device, and can be fixed to the equipment frame by expansion bolts or welding to ensure that the device does not shift under heavy load conditions. The base mounting cover is fixed by mounting bolts, which makes installation and disassembly convenient and facilitates subsequent maintenance and repair of internal components. At the same time, the hollow cavity of the base mounting cover provides clearance space for the lifting and lowering movement of the mounting column, avoiding structural interference.

The transverse mounting beam 5 is fixedly installed between the two mounting columns 4, providing a central fixed support for the cable sheave mounting seat 6, and also providing an installation foundation for the pressure detection plate 22, ensuring the installation stability of the cable sheave frame 7 and the pressure monitoring mechanism, achieving coordinated operation of cable sheave operation and load monitoring. The cable sheave mounting seat 6 is fixedly installed at the top center of the transverse mounting beam 5, providing a rotating installation foundation for the cable sheave frame 7, ensuring the cable sheave frame 7 can rotate flexibly to adapt to changes in the running direction of the cable 9, preventing the cable 9 from tangling or...

Meanwhile, its bottom sides are fixed... The shock-absorbing telescopic column 20 can achieve a two-stage elastic buffer function, absorbing the impact load during the operation of the cable 9 and ensuring the stable operation of the cable pulley mechanism. The cable pulley disc 8 is rotatably mounted on the cable pulley frame 7 and is made of high-strength wear-resistant material. Through rolling cooperation with the cable 9, it realizes the guidance and transmission of the cable 9. The groove structure can prevent the cable 9 from slipping or falling off during transmission, ensuring the smoothness and safety of the cable group transmission. The symmetrical design of the two cable pulley discs 8 can enhance the stability of the cable 9 transmission and improve the load-bearing capacity.

[0025] The cable assembly base 1 has an internal cavity 11. Both sides of the internal cavity 11 have lifting and limiting grooves 12. Inside the cable assembly base 1, there is a hydraulic power unit 17 and two hydraulic lifting columns 18. The tops of the two hydraulic lifting columns 18 are fixedly connected to the inner top of the lifting seat 3. The lifting seat 3 is a frame with its opening facing downwards. The lifting seat 3 achieves lifting and lowering within the cable assembly base 1 via the two hydraulic lifting columns 18. Two limiting plates 16 are fixedly installed on both sides of the lifting seat 3. The four limiting plates 16 slide and rise within four corresponding lifting and limiting grooves 12, thereby achieving a lifting and limiting stabilizing function for the lifting seat 3. A shock-absorbing telescopic column 20 is fixedly installed on both sides of the bottom of the cable wheel frame 7. Vibration damping pads 21 are fixedly installed at the bottom of each of the expansion joints 20. Pressure detection plates 22 are fixedly installed at the top of each of the two vibration damping pads 21, corresponding to the top of the transverse mounting beam 5. Pressure detectors 23 are connected to the bottom of each pressure detection plate 22. A rotating joint 13 is installed at the bottom of each pressure detector 23. A bottom mounting seat 14 is rotatably connected to the inner wall of the bottom end of the rotating joint 13. A bottom fixing seat 15 is fixedly connected to the bottom end of the bottom mounting seat 14. A sliding block 24 is fixedly connected to the bottom end of the bottom fixing seat 15. A telescopic rod 25 is installed on one side of the outer wall of the sliding block 24 and is fixed to one side of the mounting column 4. A push terminal 27 is fixedly connected to the other side of the outer wall of the sliding block 24. The sliding block 24 and the telescopic rod 25 are slidably connected to the inner wall of the limiting slot frame 26. One end of the pushing terminal 27 is fixedly connected to the limiting frame 28. The inner wall of the limiting frame 28 is rotatably connected to a rotating arm 29. The end of the rotating arm 29 away from the pushing terminal 27 is located on one side of the cable sheave mounting seat 6. A spring pull rod 30 is installed between the rotating arms 29. The shock-absorbing telescopic column 20 is fixedly installed on both sides of the bottom of the cable sheave frame 7. The shock-absorbing pad 21 is fixedly installed at the bottom of the shock-absorbing telescopic column 20. The two work together to form a two-stage elastic buffer structure. The first stage absorbs the impact load through the elastic expansion and contraction of the shock-absorbing telescopic column 20. The second stage further buffers the vibration through the elastic deformation of the shock-absorbing pad 21, effectively absorbing the start-stop impact during the operation of the cable 9. To prevent load fluctuations and avoid the transmission of impact loads to other components, ensuring the overall stable operation of the device and extending its service life, the pressure detection plate 22 is fixedly installed on the top of the transverse mounting beam 5, corresponding to the position of the shock-absorbing pad 21, and is made of high-strength pressure sensing material. The pressure detector 23 is connected to the bottom of the pressure detection plate 22 and has high-precision pressure detection and signal transmission functions. Its core function is to monitor the pressure signal transmitted by the shock-absorbing pad 21 in real time. This pressure signal indirectly reflects the tension and operating load changes of the cable 9. The rotating joint 13 is installed at the bottom end of the pressure detector 23, and the bottom mounting seat 14 is rotatably connected to the bottom inner wall of the rotating joint 13. The bottom fixing seat 15 is fixedly connected to the bottom end of the bottom mounting seat 14.The three components work together to achieve a flexible rotational connection between the pressure detector 23 and the sliding block 24, ensuring that the pressure detector 23 maintains a reasonable force angle during elastic adjustment, avoiding a decrease in pressure detection accuracy due to angle deviation, and ensuring the accuracy of monitoring data. The sliding block 24 is fixedly connected to the bottom end of the bottom fixing seat 15, and the telescopic rod 25 is fixed to one side of the mounting fixing column 4 and connected to one side of the outer wall of the sliding block 24. The limiting groove frame 26 provides sliding guidance for the sliding block 24, the telescopic rod 25, and the pushing terminal 27. The sliding block 24 is driven by the elastic extension and contraction of the telescopic rod 25. The movable block 24 slides flexibly along the limiting slot 26, realizing the elastic adjustment of the pressure monitoring mechanism. Combined with the shock-absorbing telescopic column 20, this further enhances the device's buffering performance. Simultaneously, the limiting slot 26 restricts the sliding direction of the sliding block 24, preventing deviation and ensuring the stability of the elastic adjustment. The pushing terminal 27 is fixedly connected to the other side of the outer wall of the sliding block 24, and the limiting frame 28 is fixedly connected to one end of the pushing terminal 27. The rotating arm 29 is rotatably connected to the inner wall of the limiting frame 28, and the spring rod 30 is installed between the two rotating arms 29. The spring rod 30 possesses excellent elastic performance. Its core function is to form an elastic linkage structure. When the sliding block 24 slides, the pushing terminal 27 drives the limiting frame 28 and the rotating arm 29 to rotate. The spring rod 30 absorbs vibration and impact during the adjustment process through its own elastic extension and contraction, further enhancing the device's dual-stage elastic buffering effect. At the same time, this structure limits the sliding stroke of the sliding block 24, preventing excessive sliding and damage to components, and ensuring the reliability of the elastic adjustment.

[0026] A controller 19 is installed inside the base cavity 11 of the cable assembly base 1. The controller 19 contains a network communication module and is connected to two pressure detectors 23. Based on the detection values ​​of the two pressure detectors 23, the controller 19 controls the hydraulic power unit 17 to operate, thereby raising and lowering the lifting seat 3 and controlling the tension of the cable 9 on the two cable sheave frames 7. As the core control unit of the device, the controller 19 can automatically determine whether the cable 9 is slack and whether the force is balanced by analyzing the data transmitted by the pressure detectors 23. When the pressure value is lower than the preset threshold, the controller controls the hydraulic lifting column 18 to extend and drive the cable sheave 8 to rise and tighten the cable 9. When the pressure difference between the two sides exceeds the preset range, the height of the lifting seat 3 can be finely adjusted or the cable sheave frame 7 can be rotated. The adaptive adjustment ensures balanced force on cable 9. The network communication module can upload operating data and pressure parameters to the remote monitoring platform in real time, facilitating remote monitoring and fault warning by staff, and realizing intelligent control. A base 10 is fixedly installed at the bottom of the cable assembly base 1, which fixes the entire device and provides a stable installation foundation. It can be fixed to the equipment frame by expansion bolts or welding to ensure that the device does not shift under heavy load conditions. The base mounting cover 2 is fixed by mounting bolts, which is convenient for installation and disassembly, and facilitates subsequent maintenance and repair of internal components. At the same time, the hollow cavity of the base mounting cover 2 provides clearance for the lifting and lowering movement of the mounting column 4, avoiding structural interference. Working principle: The device is fixed to the target equipment frame via the base 10. After connecting the cable 9 to the cable reel 8 and the load, and checking the tightness of each component connection, the device is started. When the cable 9 is subjected to load or instantaneous impact, the cable reel frame 7 rotates slightly under force. The bottom shock-absorbing telescopic column 20 absorbs the first-stage impact energy through elastic deformation, and the shock-absorbing pad 21 weakens the rigid collision through its own flexible buffer, forming the second-stage shock absorption. The double buffer effectively reduces vibration transmission. After being compressed, the shock-absorbing pad 21 adheres tightly to the pressure detection plate 22. The pressure detector 23 collects the pressure data on both sides in real time and transmits the data to the controller 19. The controller 19 compares the pressure data with a preset threshold. If the pressure value is less than the normal threshold, the controller 19 starts the hydraulic power unit 17. The hydraulic lifting column 18 is extended, causing the lifting seat 3 to move upward along the lifting limit groove 12. The cable wheel 8 rises synchronously to tension the cable 9 until the pressure value reaches the preset range. If the pressure difference between the two sides is too large, the controller 19 fine-tunes the extension and retraction of the hydraulic lifting column 18, or the cable wheel frame 7 rotates adaptively to make the force on both sides more balanced. If the pressure value is greater than the maximum value, it is judged as overload. The controller 19 sends a warning signal through the network communication module and controls the hydraulic lifting column 18 to retract slightly to avoid the cable 9 from breaking due to overload. During the movement of the lifting seat 3, the limit plate 16 slides smoothly in the lifting limit groove 12 to ensure that the position of the cable wheel 8 is stable and the cable 9 does not deviate. The staff can view the pressure data and lifting status in real time through the remote platform, which is convenient for maintenance.
