Description

Technical Field

[0001] This utility model belongs to the field of flexible gate technology, specifically relating to a device for detecting the loosening of steel wire rope in a flexible lifting gate. Background Technology

[0002] When the lifting mechanism of the flexible lifting gate rises, the steel wire rope on the hoist pulls the lower guide beam upward, stacking the curtain fixing frame and curtain on the lower guide beam. After opening to the correct position, the upper travel limit switch stops the movement. When the lifting mechanism descends, the lower guide beam moves downward, closing the gate. When the gate is fully closed, the travel limit switch on the rope pulley stops the movement. If the steel rope breaks during gate operation, the safety mechanism activates to prevent the gate from falling.

[0003] Without a wire rope anti-loosening detector, if the gate is subjected to external force, the increased lifting weight will cause the wire rope to break during normal operation of the power unit, resulting in losses and serious safety hazards. The operation of flexible lifting gates relies on the traction of wire ropes. These wire ropes may be damaged by various factors during long-term use, including but not limited to wear, corrosion, fatigue, and improper operation. When the wire rope reaches its load-bearing limit, it may break, or even if it has been overstretched before reaching the breakage point, its strength and stability will decrease significantly, leading to uncontrolled descent of the flexible gate. Once the wire rope breaks or loses sufficient tension, the flexible lifting gate... If the gate loses its support, it may suddenly and uncontrollably drop, which may not only damage the gate but also pose a safety hazard to equipment, personnel, or goods below. As a key component driving the flexible lifting gate, the winch may experience a decrease in working accuracy due to wear, aging, or improper maintenance after long-term use. When the winch cannot accurately control the length of the wire rope, over-winding may occur. Over-winding of the wire rope may cause the flexible gate to stop or rebound before reaching the predetermined position, which may then collide with the frame, wall, or other fixed structures. Such impacts may not only damage the gate but also threaten the structural safety of the building. Utility Model Content

[0006] frame;

[0007] An anti-loosening protection component is installed on the outer wall of the frame. This component includes an installation chamber, a winch, a pulley block, an installation platform, a storage shell, a limiting frame, an installation bracket, a tension wheel, a torsion bar, a locking rod, a return spring, a tension spring, a top rod, and a fine-tuning rod. The installation chamber is fixedly installed at the top of the outer wall of the frame. The winch is fixedly installed on the inner wall of the installation chamber. The pulley block is rotatably embedded in the inner wall of the installation chamber via a bracket. The installation platform is fixedly installed on the inner wall of the installation chamber. The storage shell is fixedly installed at the top of the inner wall of the frame. The limiting frame is fixedly installed at the bottom of the inner wall of the installation chamber. The mounting bracket is slidably embedded in the slotted inner wall of the limiting bracket. The tensioning wheel is rotatably embedded in the inner wall of the mounting bracket. The torsion bar is rotatably inserted into the outer wall of the mounting bracket. The outer wall of the limiting bracket has a limiting groove. The snap-fit ​​rod is slidably embedded in the inner wall of the limiting groove. One end of the return spring is fixedly set in the outer wall of the snap-fit ​​rod. The other end of the return spring is fixedly set in the outer wall of the limiting bracket. One end of the tension spring is fixedly set in the bottom of the outer wall of the mounting bracket. The top rod is slidably embedded in the inner wall of the mounting chamber. The top rod and the snap-fit ​​rod are matched with each other.

[0008] Furthermore, a movable plate is slidably embedded in the inner wall of the storage shell, and storage cylinders are fixedly installed on both sides of the inner wall of the storage shell, with support springs fixedly installed on the inner wall of the storage cylinders.

[0009] Furthermore, the bottom end of the support spring is fixedly disposed at the top of the outer wall of the movable plate, and the fine-tuning rod is fixedly disposed at the top of the outer wall of the movable plate.

[0010] Furthermore, the winch, pulley block, and tensioning wheel are matched with each other.

[0012] Furthermore, the torsion bar and the snap-fit ​​bar are matched with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The flexible folding gate compresses the moving plate, which in turn raises the fine-tuning rod and compresses the top rod. This series of chain reactions automatically adjusts the rope tension. When the gate folds, the tension wheel automatically descends under the action of the tension spring, releasing the rope tension and effectively preventing the gate from colliding with the frame or other components due to winch inaccuracies. The cooperation between the torsion bar and the locking rod ensures that the mounting bracket and tension wheel remain stably in place when tension adjustment is not required. When adjustment is needed, the locking rod can smoothly disengage from the torsion bar, allowing the tension wheel to move freely. This mechanism greatly improves the safety and reliability of the device. The moving plate and support spring inside the housing together form a buffer and support system. When the flexible gate folds and compresses the moving plate, the support spring absorbs some of the impact force, protecting the device from damage, while ensuring that the fine-tuning rod can rise smoothly. The entire anti-loosening protection assembly is designed to be quite compact, with tight and efficient cooperation between the various components. This not only ensures the overall stability and durability of the device but also makes it more flexible and convenient in practical applications. Attached Figure Description

[0024] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0025] A flexible lifting gate wire rope anti-loosening detection device includes,

[0026] Framework 1;

[0027] The anti-loosening protection assembly is located on the outer wall of frame 1. The assembly includes an installation chamber 3, a winch 4, a pulley block 5, an installation platform 6, a storage shell 7, a limiting bracket 8, an installation frame 9, a tension wheel 10, a torsion bar 11, a locking rod 12, a return spring 13, a tension spring 14, a top rod 15, and a fine-tuning rod 16. The installation chamber 3 is fixedly installed at the top of the outer wall of frame 1. The winch 4 is fixedly installed on the inner wall of the installation chamber 3. The pulley block 5 is rotatably embedded in the inner wall of the installation chamber 3 via a bracket. The installation platform 6 is fixedly installed on the inner wall of the installation chamber 3. The storage shell 7 is fixedly installed at the top of the inner wall of frame 1. The limiting bracket 8 is fixedly installed at the bottom of the inner wall of the installation chamber 3. At the mounting bracket 9, the mounting frame 9 is slidably embedded in the slotted inner wall of the limiting frame 8. The tensioning wheel 10 is rotatably embedded in the inner wall of the mounting bracket 9. The torsion bar 11 is rotatably inserted into the outer wall of the mounting bracket 9. The outer wall of the limiting frame 8 has a limiting groove 801. The locking rod 12 is slidably embedded in the inner wall of the limiting groove 801. One end of the return spring 13 is fixedly set in the outer wall of the locking rod 12. The other end of the return spring 13 is fixedly set in the outer wall of the limiting frame 8. One end of the tension spring 14 is fixedly set in the bottom of the outer wall of the mounting bracket 9. The top rod 15 is slidably embedded in the inner wall of the mounting chamber 3. The top rod 15 and the locking rod 12 are matched with each other. The fine adjustment rod 16 is matched with the top rod 15.

[0028] In a specific embodiment of this utility model, the folded flexible gate presses against the moving plate 17, which in turn drives the fine-tuning rod 16 to rise and press against the top rod 15. This series of chain reactions can automatically adjust the tension of the rope. When the gate is folded, the tension wheel 10 automatically descends under the action of the tension spring 14, releasing the tension of the rope. This effectively avoids the gate hitting the frame 1 or other components due to the accuracy problem of the winch 4. The cooperation between the torsion bar 11 and the locking rod 12 ensures that the mounting bracket 9 and the tension wheel 10 can be stably kept in their original positions when no tension adjustment is needed. When adjustment is needed, the locking rod 12... The ability to smoothly release the locking mechanism of the torsion bar 11, allowing the tension wheel 10 to move freely, greatly improves the safety and reliability of the device. The movable plate 17 and the support spring 19 inside the housing 7 together form a buffer and support system. When the flexible door folds and squeezes the movable plate 17, the support spring 19 can absorb part of the impact force, protecting the device from damage, while ensuring that the fine-tuning rod 16 can rise smoothly. The entire anti-loosening protection assembly is designed to be quite compact, and the cooperation between the various components is tight and efficient. This not only ensures the overall stability and durability of the device, but also makes it more flexible and convenient in practical applications.Two limit sensors are installed on the top of the outer wall of the mounting platform 6 to monitor the rope and prevent overstretching when the flexible gate is pulled up. When the flexible lifting gate is fully extended or in a preset position, the tension wheel 10 is held at a certain height by the tension spring 14, ensuring the wire rope maintains appropriate tension. The locking rod 12, under the action of the return spring 13, is tightly locked onto the torsion bar 11 to prevent accidental movement of the mounting frame 9 and the tension wheel 10. The fine-tuning rod 16 is held at a lower position within the storage shell 7 due to the weight of the moving plate 17 and the support spring 19. When the flexible lifting gate needs to be folded, the gate begins to fold downwards or inwards. As the gate folds, part or all of the gate gradually presses against the moving plate 17. After being pressed by the gate, the moving plate 17 begins to move upwards. When both sensors fail, the support spring 19 is compressed and the fine-tuning rod 16 rises. After the fine-tuning rod 16 rises, it connects... When the top rod 15 is touched and pushed upward, the rise of the top rod 15 causes the locking rod 12 to slide within the limiting groove 801, the return spring 13 is compressed, and the locking rod 12 releases its locking onto the torsion bar 11. After the torsion bar 11 is no longer locked, the mounting bracket 9 and the tension wheel 10 begin to move downward under the tension of the tension spring 14. As the tension wheel 10 descends, the wire rope that was originally kept taut by the tension wheel 10 quickly releases its tension. This process helps to reduce the risk of the gate hitting the frame 1 or other components due to insufficient accuracy or operation delay of the winch 4. When the gate is fully folded into place, the entire anti-loosening protection assembly returns to a relatively static state, waiting for the next unfolding operation. Before the gate is ready to be unfolded again, the fine-tuning rod 16 and the moving plate 17 can be reset to their initial positions by the support spring. The locking rod 12 is re-locked onto the torsion bar 11 under the action of the return spring 13, preparing for the next folding operation.

[0029] Specifically, a movable plate 17 is slidably embedded in the inner wall of the storage shell 7, and storage cylinders 18 are fixedly installed on both sides of the inner wall of the storage shell 7, and a support spring 19 is fixedly installed on the inner wall of the storage cylinder 18.

[0030] In a specific embodiment of this utility model, a support spring 19 is fixedly provided on the inner wall of the storage tube 18, which can assist the moving plate 17 in resetting.

[0031] Specifically, the bottom end of the support spring 19 is fixedly installed at the top of the outer wall of the movable plate 17, and the fine-tuning rod 16 is fixedly installed at the top of the outer wall of the movable plate 17.

[0032] In a specific embodiment of this utility model, the fine-tuning rod 16 is fixedly installed at the top of the outer wall of the movable plate 17, which can conveniently adjust the rising height of the push rod 15.

[0033] Specifically, the winch 4, pulley block 5, and tensioner 10 are matched with each other.

[0034] In a specific embodiment of this utility model, the winch 4, pulley block 5 and tensioning wheel 10 are matched with each other to ensure the guidance of the rope.

[0035] Specifically, anti-fall slide rails 2 are fixedly installed on both sides of the inner wall of frame 1.

[0036] In a specific embodiment of this utility model, anti-fall rails 2 are fixedly installed on both sides of the inner wall of the frame 1 to prevent the flexible door from falling.

[0037] Specifically, torsion bar 11 and snap-fit ​​rod 12 are matched with each other.

[0038] In a specific embodiment of this utility model, the torsion bar 11 and the snap-fit ​​bar 12 are matched with each other to ensure the limiting and fixing of the mounting bracket 9.

[0039] Working principle:

[0040] The folding flexible gate compresses the moving plate 17, which in turn drives the fine-tuning rod 16 to rise and compress the top rod 15. This series of chain reactions automatically adjusts the rope tension. When the gate folds, the tension wheel 10 automatically descends under the action of the tension spring 14, releasing the rope tension and effectively preventing the gate from colliding with the frame 1 or other components due to the accuracy of the winch 4. The cooperation between the torsion bar 11 and the locking rod 12 ensures that the mounting bracket 9 and the tension wheel 10 can remain stably in place when tension adjustment is not required, and that the locking rod 12 can smoothly disengage when adjustment is needed. The snap-fit ​​mechanism of the torsion bar 11 allows the tension wheel 10 to move freely, which greatly improves the safety and reliability of the device.
