Description

Technical Field

[0001] This invention relates to the field of wire rope fall arresters, specifically a convenient installable and detachable wire rope fall arrester for preventing scaffolding from falling. Background Technology

[0002] Fall arrestors are the core safety component of attached lifting scaffolds. Their main function is to quickly lock in the event of a sudden fall, preventing accidents. Their working principle largely relies on mechanical triggering mechanisms, such as using loss-of-load rebound, centrifugal force, or gravity sensing, to initiate self-locking within 0.05 seconds, fixing the scaffold to the guide rails or building structure, ensuring safety during high-altitude operations. Modern designs tend towards integration; wall-mounted supports often combine load-bearing, fall arrest, tilt prevention, and guidance functions, improving response speed and system stability. Some high-end equipment also employs double-locking or star-wheel structures to enhance redundant protection and avoid single-point failures. According to national construction safety regulations, climbing scaffolds must be equipped with standard fall arrestors. In high-rise building construction, this device not only protects workers but also prevents materials from falling and injuring people, serving both personal and public safety purposes.

[0003] Existing steel wire rope fall arrestors for climbing scaffolds can only pull steel wires. When multiple steel wires connect the climbing scaffold and the fall arrestor, deformation of the climbing scaffold may cause some steel wires to be unloaded, resulting in excessive stress on the remaining steel wires. In severe cases, this can lead to the steel wires breaking and losing their fall protection function. Summary of the Invention

[0013] The present invention has the following beneficial effects: 1. This portable, detachable wire rope fall arrestor for preventing scaffolding from falling works by having two protruding blocks slide relative to each other into a rotating disc. The first clamping device then holds the wire rope to its outer surface. An auxiliary device pulls the wire rope to one end, adjusting its overall tension to ensure each wire rope is stressed, thus increasing overall tensile strength and reducing the risk of wire breakage and loss of fall protection.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 Please see Figures 1-2 A portable, detachable wire rope fall arrester for preventing scaffolding from falling, comprising: Support 1, one end of which is rotatably connected to a rotating disk 10; Slider 2 is slidably connected to one end of bracket 1; Limiting plate 3 is connected to one end of slider 2. A first clamping device 7 is installed on one side of limiting plate 3, and an auxiliary device 8 is installed on the other side of limiting plate 3. A second clamping device 9 is installed at one end of auxiliary device 8. The tension of the wire rope is adjusted by clamping the first clamping device 7 and the second clamping device 9. Extending block 4, one end of which is connected to one end of slider 2, and a locking rod 5 for connecting wire rope is installed at one end of extending block 4; It also includes a slide rail groove 12, which passes through the bracket 1 and the slider 2; Electric slide rails 13 are installed at the upper and lower ends of slider 2, and the electric slide rails 13 are slidably connected to the slide rail groove 12.

[0024] Existing steel wire rope fall arrestors for climbing scaffolds can only pull steel wires. When multiple steel wires connect the climbing scaffold and the fall arrestor, deformation of the climbing scaffold may cause some steel wires to be unloaded, resulting in excessive stress on the remaining steel wires. In severe cases, this can lead to the steel wires breaking and losing their fall protection function.

[0025] according to Figure 1 As shown, safety buckles are installed at both ends of the wire rope. The two safety buckles are connected to the locking rod 5 and the climbing frame respectively, so as to achieve the effect of convenient quick disassembly. In the event of a scaffold falling, safety is ensured by pulling steel wire ropes to prevent further falls. When the climbing scaffold falls and hits the stairs or is deformed by friction, the steel wire ropes connected to the climbing scaffold will be partially stressed and partially unstressed. When the steel wire is under excessive stress, it will break and lose its fall protection function. Therefore, in this embodiment, an electric slide rail 13 is installed. The electric slide rail 13 drives the extension block 4 to slide, so that the two extension blocks 4 drive the two steel wire ropes to move closer to each other. Then, the motor drives the rotating disk 10 to rotate, which drives the slider 2 and the extension block 4 to rotate. The extension block 4 drives the locking rod 5 and the steel wire rope to rotate, so that the two steel wire ropes rotate and twist together to form a single steel wire rope, thereby improving the overall tensile strength and reducing the occurrence of partial unstressed steel wires. Further reading Figure 1 By sliding two protruding blocks 4 relative to each other and engaging them with the rotating disk 10, and then clamping them on the outer surface of the wire rope by the first clamping device 7, the wire rope is pulled to one end by the auxiliary device 8 to adjust the overall tension of the wire rope, thereby ensuring that each wire rope is under force and improving the overall tensile strength, thereby reducing the risk of wire breakage and loss of fall protection. Then, the two protruding blocks 4 are rotated to allow the two wires with the same tension to rotate and wrap around each other, thereby ensuring the overall tensile strength of the wire rope is reduced. It should be noted that an electric locking device is installed at the electric slide rail 13 to prevent the protruding block 4 from sliding.

[0026] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-3 The first adjusting device 6 includes a first piston chamber 61 disposed inside the limiting plate 3. A first piston plate 65 is slidably connected inside the first piston chamber 61. The first piston plate 65 is connected to the limiting plate 3 by a first spring 66. One side of the first clamping device 7 is connected to one side of the first piston plate 65. The limiting plate 3 is also provided with an inlet hole 62 and a pressure relief hole 63 inside, and the first piston chamber 61, the inlet hole 62 and the pressure relief hole 63 are connected. The first pressure relief valve 64 is installed inside the pressure relief hole 63; The first clamping device 7 includes a first piston plate 65 connected to one side of the first clamping plate 71. A first hydraulic cylinder 72 is installed at the upper end of the first clamping plate 71. A first pipe and a second pipe are installed on one side of the first hydraulic cylinder 72. One end of the first pipe and the second pipe is connected to a water pump. The lower end of the first clamping plate 71 is slidably connected to the first clamping plate 73, and the upper end of the first clamping plate 73 is connected to the slide rod inside the first hydraulic cylinder 72. There are two first clamping plates 73, and a first clamping groove 74 is provided between the two first clamping plates 73.

[0027] Driver: According to Figure 2 and Figure 3 As shown, when the two protruding blocks 4 slide to the rotating disk 10, the sensor at the rotating disk 10 sends a signal to the water pump, so that the water pump transmits liquid to the inside of the first hydraulic cylinder 72 through the first pipe, thereby pushing the first hydraulic cylinder 72 to drive the first clamping plate 73 to abut against the outer surface of the wire rope. In this way, the wire rope is clamped by the two first clamping plates 73. The first hydraulic cylinder 72 is a hydraulic cylinder, and its working principle will not be described in detail. After the first clamping plate 73 is clamped, liquid is pumped to the inlet 62 by a water pump, which pushes the first piston plate 65 to slide to one end. The first piston plate 65 drives the first clamping device 7 to move, thereby pulling the wire rope and adjusting the tension of the wire rope. Since the pressure relief hole 63 is equipped with a first pressure relief valve 64, the pressure relief value of the first pressure relief valve 64 is equal to the tension value. Thus, when the tension of the wire rope is greater than the hydraulic value, the first piston plate 65 will not be able to slide, which will cause the first pressure relief valve 64 to open, thereby completing the pressure relief and keeping both wire ropes under tension.

[0028] Example 3 This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-3 The auxiliary device 8 includes a second piston chamber 81 disposed inside the limiting plate 3. A second piston plate 82 is slidably connected inside the second piston chamber 81. One end of the second piston plate 82 is connected to the inside of the limiting plate 3 by a return spring. A rotating plate 83 is rotatably connected to one side of the second piston plate 82, and the rotating plate 83 and the second piston plate 82 are connected by a torque spring. One side of the second clamping device 9 is connected to one end of the rotating plate 83, and the steel wire rope is struck by the second clamping device 9. A second hydraulic cylinder 84 is also installed on one side of the limiting plate 3. The second hydraulic cylinder 84 is used to abut against the other end of the rotating plate 83. The second clamping device 9 includes two second clamping plates 91 connected to one side of the rotating plate 83, and a third hydraulic cylinder 92 is installed at the upper end of the second clamping plate 91. The lower end of the second clamping plate 91 is equipped with a second clamping plate 93, and the third hydraulic cylinder 92 is used to drive the second clamping plate 93 to slide. A second clamping groove 94 is provided between the two second clamping plates 93.

[0029] according to Figure 3 As shown, the sliding of the two protruding blocks 4 causes the wire ropes to move closer together. However, when the two wire ropes are in a figure-eight shape, the rotation of the rotating disk 10 cannot quickly wind the two wire ropes together, and the winding is uneven. Therefore, by installing a rotating plate 83 and a second clamping device 9 on one side of the limiting plate 3, the second clamping device 9 has the same structure as the first clamping device 7, both clamping the wire ropes. Therefore, according to... Figure 5 As shown, the second hydraulic cylinder 84 is pushed by hydraulic pressure to slide, and the second hydraulic cylinder 84 is used to squeeze one end of the rotating plate 83, so that one end of the rotating plate 83 drives the second clamping device 9 to rotate and squeeze the wire ropes closer to each other, thereby reducing the distance between the two wire ropes near the protruding block 4, thereby improving the winding efficiency. Furthermore, since there are steel frames or other obstacles around the connection between the wire rope and the protruding block 4, the wire rope may be rubbed by the obstacles when the climbing frame falls and shakes, which may further aggravate metal fatigue or partial breakage. Therefore, in this embodiment, a second piston chamber 81 is slidably connected to one side of the limiting plate 3. The second piston chamber 81 is hydraulically driven to slide, which in turn drives the second piston plate 82 to slide. The second piston plate 82 drives the rotating plate 83 to slide, and the rotating plate 83 drives the second clamping device 9 to move, thereby adjusting the clamping position of the second clamping device 9. Thus, when there is a breakage at the position of the wire rope clamped by the first clamping device 7, the second clamping device 9 can clamp the wire rope again to ensure that it will still be firmly clamped and will not break. Furthermore, by changing the clamping position of the second clamping device 9, the wire rope is further guaranteed to be firmly clamped.

[0030] Example 4 This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figures 1-5 A spray gun 95 is installed at one end of the third hydraulic cylinder 92, and the adhesive is sprayed through the spray gun 95 to bond the steel wire rope. A camera 11 is also installed at one end of the protruding block 4. The camera 11 captures images of the wire rope to calculate and determine the fatigue value and weak points of the wire rope. The fatigue value and weak point of the wire rope are used to adjust the spray gun's 95-degree spray angle for the colloid.

[0031] according to Figure 4 As shown, in order for the second clamping device 9 to clamp the front end of the wire rope at the point of breakage or fatigue, the camera 11 captures an image of the wire rope. Specifically: Using visible light imaging, computer vision, and artificial intelligence, non-contact inspection of the surface of steel wire ropes is carried out to automatically identify single or multiple broken wires, surface cracks, especially fatigue cracks, wear, corrosion, deformation, and other structural defects. S1. To ensure the capture of minute defects, such as cracks or broken wire ends at the 0.1 mm level, a high-resolution industrial camera must be selected, with either an area scan camera or a line scan camera chosen based on the application scenario. Regarding lighting, due to the highly reflective nature of the steel wire rope surface, a specialized light source strategy must be employed. For example, a ring LED light source combined with low-angle oblique illumination can enhance the detail of surface irregularities. Simultaneously, a combination of polarized light sources and polarized lenses can be introduced to effectively suppress specular reflection interference. For moving steel wire ropes, the linear velocity is measured by an encoder and synchronized with the camera's trigger signal to achieve frozen imaging, avoiding motion blur and thus acquiring the original image.

[0032] S2. The original image typically contains noise, uneven lighting, and background interference, requiring processing to improve the accuracy of subsequent analysis. First, median filtering or nonlocal mean denoising algorithms are used to remove random noise. Second, homomorphic filtering or white balance correction is used to eliminate uneven lighting. Then, CLAHE contrast-limited adaptive histogram equalization or the Retinex algorithm is used to enhance local contrast, making minor defects more apparent. Subsequently, the main area of ​​the steel wire rope is segmented using the Otsu thresholding method or adaptive thresholding, and morphological operations such as opening and closing operations are combined to remove isolated noise points and fill holes. Finally, the region of interest (ROI) for analysis is extracted, thus completing the image processing.

[0033] S3. Based on the image processing, the Canny edge detection combined with morphological skeletonization can identify the end features of broken wires. The Gabor filter or wavelet transform can be used to extract directional textures for fatigue crack detection. The change in wire diameter can be calculated by edge fitting to quantify the degree of wear. The Hough transform or strand spacing analysis can be used to determine whether the structure has undergone deformation such as birdcage. In this way, image data is obtained and detection results are output.

[0034] S4. Extract quantifiable indicators from the test results as a basis for safety judgment. These indicators include the number of broken wires per unit length (e.g., wires / meter), broken wire density, maximum crack length and its propagation direction (fatigue cracks typically propagate axially), wire diameter reduction rate (compare measured diameter with nominal diameter), and the coefficient of variation of strand spacing, reflecting the degree of structural looseness. Based on these indicators, the condition of the wire rope can be graded according to international or national standards. For example, no broken wires and a diameter loss of less than 3% are considered healthy; 3 to 6 broken wires per meter or localized wear exceeding 5% indicate moderate fatigue, which is unsafe and must be avoided before clamping to improve clamping safety.

[0035] Furthermore, based on the clamping point data determined above, the clamping position of the second piston chamber 81 driven by the second clamping device 9 is adjusted. Then, a spray gun 95 is installed at one end of the third hydraulic cylinder 92. Hot vulcanizing adhesive is sprayed through the spray gun 95, thereby using structural adhesive to wrap the two steel wire ropes, so that the intertwined steel wire ropes can be better bonded. It should be noted that the spray gun 95 is connected to the glue spraying machine, and the spraying position and spray volume of the spray gun 95 are dynamically adjusted based on the processing results of the above images, so that the two steel wire ropes can be better bonded together.

[0036] Furthermore, in order to improve the accuracy of image processing, the second hydraulic cylinder 84 pushes the extrusion rotating plate 83 multiple times, thereby causing the rotating plate 83 to drive the second clamping device 9 to strike the wire rope multiple times. Since the wire rope is under a certain tension at this time, the repeated striking of the wire rope can not only remove excess dust and debris on the wire rope that affect the adhesive adhesion, but also accelerate the occurrence of metal fatigue fracture. This allows the camera 11 to capture more data of the wire rope, thereby making accurate data calculation results.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
