Abstract
Description
Technical Field
[0001] This application relates to the technical field of fall protection, and in particular to a safety testing device for a safety lock on a suspended platform for high-altitude operations. Background Technology
[0002] In building exterior decoration, cleaning, and maintenance operations, suspended platforms are indispensable personnel-carrying equipment and have been widely used in the field of building exterior construction in recent years. However, accidents involving injuries and fatalities caused by suspended platforms occur frequently during actual construction, primarily due to the unstable reliability of their safety locks. When the working wire rope breaks, one end of the suspended platform slips causing it to tilt at a certain angle, or the platform descends too quickly, the safety lock must quickly and automatically tighten the safety rope to prevent the suspended platform from sliding or tilting, thereby avoiding a fall accident.
[0003] The national mandatory standard GB19155 clearly stipulates the inspection requirements for the locking speed, locking angle, and locking distance of safety locks. Type testing also requires a safety lock slippage test. In situations involving sudden strong winds or during the descent or ascent of the suspended platform, the platform may rotate along its lateral plane. If the wire rope suddenly breaks, the rotation amplitude increases further. Therefore, it is necessary to combine the braking distance of the safety lock with the rotation amplitude of the suspended platform during braking to define the safety performance of the safety lock. Existing testing equipment is limited in function, generally only able to measure the braking distance of the safety lock, which is insufficient to guarantee the safe operation of suspended platforms used for high-altitude operations.
[0004] Patent (202420030041.4) discloses a test device for the fall prevention function of a safety lock on a suspended platform for high-altitude operations. The device includes a steel frame, a lifting mechanism, a release mechanism, a measurement system, and a control system. When the working wire rope of the suspended platform breaks, it measures the impact force on the safety wire rope and the distance the safety lock slides down. While this patent improves the detection efficiency of the safety lock, its detection method is limited and it cannot be used to test for actual sudden falls from the platform, thus failing to guarantee the safety of workers when the platform falls suddenly and rotates.
[0005] Regarding the aforementioned technologies, the inventors believe that existing testing devices have the drawback of being limited in function and unable to fully determine whether a safety lock is qualified. Summary of the Invention
[0006] To address the aforementioned technical problems, this application provides a safety testing device for a safety lock on a suspended platform for high-altitude operations.
[0007] This application provides a safety testing device for a safety lock on a suspended platform for high-altitude operations, which adopts the following technical solution:
[0008] A safety testing device for a suspended platform safety lock for high-altitude operations includes a suspended platform, an angle detection unit disposed at the bottom of the suspended platform, and distance sensors disposed on both sides of the suspended platform; an extension unit is provided below the suspended platform; the bottom of the extension unit is fixed to the ground; the top of the extension unit has an extension portion; the extension portion is rotatably connected to the bottom wall of the suspended platform; and a deflector is fixed on the extension portion.
[0009] The distance sensor is used to detect the braking distance of the suspended platform equipment; the angle detection unit is used to detect the deflection angle of the deflection component.
[0010] By adopting the above technical solution, by setting an angle detection unit at the bottom of the suspended platform and setting distance sensors on both sides of it, it is possible to simultaneously obtain two key parameters of the suspended platform during the braking process of the safety lock: the deflection angle and the braking distance. By rotating the extension unit and the deflection unit and setting a deflection component on the extension, it is possible to evaluate the actual state of the suspended platform when the working wire rope breaks, thereby realizing comprehensive monitoring of the safety performance indicators of the safety lock and ensuring the safety of the safety lock in actual use.
[0011] Preferably, the suspended platform equipment includes a suspended platform, two sets of lifting devices installed on the roof, two sets of working steel wire ropes, two sets of safety steel wire ropes, and two safety locks respectively installed on both sides of the suspended platform; one end of each of the two sets of working steel wire ropes is connected to the power output end of the two sets of lifting devices, and the other end is connected to both sides of the suspended platform; the top ends of the two sets of safety steel wire ropes are fixed to the roof, and the bottom ends extend downward and pass through the safety locks.
[0012] Preferably, the angle detection unit includes a central control module and a CCD camera disposed on the suspended platform equipment; the central control module is electrically connected to the CCD camera.
[0013] Preferably, the extension unit includes a winding machine and a positioning steel rope; the winding machine is installed on the ground and located directly below the suspended platform; the top end of the positioning steel rope is rotatably connected to the bottom wall of the suspended platform, and the bottom end is wound around the power output shaft of the winding machine; the deflector is fixed to the top of the positioning steel rope.
[0014] By adopting the above technical solution, the extension unit adopts a combination structure of a winding machine and a positioning steel rope. The winding machine can accurately adjust the length of the positioning steel rope by precisely controlling the rotation of the power output shaft, ensuring that the positioning steel rope is always taut. This ensures that the deflection component remains fixed when the suspended platform equipment drops sharply and rotates, thereby ensuring that the angle detection unit accurately detects the deflection angle of the suspended platform equipment with the deflection component as a reference.
[0015] Preferably, the top end of the positioning steel rope is connected to a connecting unit; the positioning steel rope is rotatably mounted on the bottom wall of the suspended platform equipment through the connecting unit.
[0016] Preferably, the connecting unit includes a connector and a sliding member; the connector is rotatably mounted on the bottom wall of the suspended platform; the sliding member is mounted on the connector and has an elastic degree of freedom to move vertically; the top end of the positioning steel rope is connected to the sliding member.
[0017] By adopting the above technical solution, the sliding component has an elastic degree of freedom to move vertically. When the suspended platform equipment generates instantaneous impact force during the simulated braking process, the sliding component can absorb part of the impact force through vertical elastic movement, reduce the rigid collision at the connection between the positioning steel rope and the suspended platform equipment, reduce the risk of damage to the device components due to long-term impact, and extend the service life of the equipment.
[0018] Preferably, a telescopic rod is fixedly provided on the bottom wall of the suspended platform equipment; one end of the deflector is rotatably connected to one end of the telescopic rod; the angle detection unit is used to detect the angle between the telescopic rod and the deflector.
[0019] By adopting the above technical solution, the telescopic rod and the deflector are rotatably connected, allowing the angle detection unit to directly detect the included angle between them. This transforms the dynamic change of the suspended platform's tilt into an angular relationship between the rods, avoiding potential errors from traditional indirect measurement methods. It provides a more intuitive reflection of the suspended platform's real-time offset state, ensuring the accuracy of angle data and providing a reliable basis for evaluating the locking performance of the safety lock at different offset angles. By fixing the telescopic rod to the bottom wall of the suspended platform equipment, it forms a stable linkage structure with the deflector. During the tilting or braking process of the suspended platform, the relative rotational relationship between the two remains stable, reducing detection deviations caused by component shaking or displacement. The rigid connection and rotational combination design of the telescopic rod and the deflector not only ensures the stability of angle detection but also enhances the anti-interference capability of the overall structure of the device, making the testing process more reliable.
[0020] Preferably, the connector is provided with an anti-rotation component that slides vertically along the upper edge; the anti-rotation component has a limiting groove; after the anti-rotation component slides, the limiting groove covers or disengages from the telescopic rod and the deflector.
[0021] By adopting the above technical solution, before the suspended platform equipment is used normally, the anti-rotation component and the telescopic rod are adjusted to be on the same axis. After the anti-rotation component moves to the position of the telescopic rod and the deflection component, the telescopic rod and the deflection component are fixed in the limiting groove. When the suspended platform equipment rises or falls, the taut positioning steel rope can limit the lateral movement of the suspended platform equipment through the anti-rotation component, preventing the suspended platform equipment from rotating excessively and improving the stability of the suspended platform equipment during normal lifting and lowering. The taut positioning steel rope can replace the counterweight block to achieve the counterweight effect of the suspended platform equipment, so that the suspended platform equipment can move stably.
[0022] Preferably, the sliding member is provided with a toggle member; one end of the toggle member passes through the connecting member and is connected to the anti-rotation member.
[0023] By adopting the above technical solution, the actuating component on the sliding component passes through the connecting component and connects with the anti-rotation component. After the sliding component moves downward, it is linked with the anti-rotation component through the actuating component. No additional power control is required, and the automatic switching of the constraint state of the anti-rotation component is realized. This not only improves the convenience of the test operation, but also ensures the stability of the suspended platform equipment during normal operation.
[0024] Preferably, the connector has a groove; the sliding member is slidably disposed vertically within the groove; a limiting block is provided at the end of the sliding member; an elastic member is provided between the limiting block and the inner wall of the groove; the elastic member is used to provide a force for the sliding member to approach the suspended platform equipment.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. By setting an angle detection unit at the bottom of the suspended platform and distance sensors on both sides, two key parameters of the suspended platform during the braking process of the safety lock can be obtained simultaneously: the deflection angle and the braking distance. By connecting the extension unit with the deflection unit and setting a deflection component on the extension, the actual state of the suspended platform when the working wire rope breaks can be evaluated. This achieves comprehensive monitoring of the safety performance indicators of the safety lock and ensures the safety of the safety lock in actual use.
[0027] 2. The extension unit adopts a combination structure of a winding machine and a positioning steel rope. The winding machine can precisely control the rotation of the power output shaft to achieve precise adjustment of the positioning steel rope length, ensuring that the positioning steel rope remains taut at all times. This keeps the deflector fixed when the suspended platform drops sharply and rotates, thus ensuring that the angle detection unit accurately detects the deflection angle of the suspended platform using the deflector as a reference. Before normal use of the suspended platform, the anti-rotation component and the telescopic rod are adjusted to be on the same axis. After the anti-rotation component slides towards the position of the telescopic rod and the deflector, the telescopic rod and the deflector are fixed in the limiting groove. When the suspended platform rises or falls, the taut positioning steel rope can laterally limit the suspended platform through the anti-rotation component, preventing excessive rotation of the suspended platform and improving the stability of the suspended platform during normal lifting and lowering. The taut positioning steel rope can replace the counterweight to achieve the counterweight effect of the suspended platform, enabling stable displacement of the suspended platform.
[0028] 3. By rotating the telescopic rod and the deflector, the angle detection unit directly detects the angle between them, transforming the dynamic change of the suspended platform's tilt into an angular relationship between the rods. This avoids errors that may occur with traditional indirect measurement methods, providing a more intuitive reflection of the suspended platform's real-time offset state and ensuring the accuracy of angle data. This provides a reliable basis for evaluating the locking performance of the safety lock at different offset angles. By fixing the telescopic rod to the bottom wall of the suspended platform, forming a stable linkage structure with the deflector, the relative rotational relationship between the two remains stable during the platform's tilting or braking process. This reduces detection deviations caused by component shaking or displacement. The rigid connection and rotational combination design of the telescopic rod and the deflector not only ensures the stability of angle detection but also enhances the overall anti-interference capability of the device, making the testing process more reliable.

[0040] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0041] This application discloses a safety testing device for a safety lock on a suspended platform used for high-altitude operations. (Refer to...) Figure 1 The system includes a suspended platform, an angle detection unit, an extension unit 2, a deflector 6, and two sets of distance sensors. The angle detection unit is located at the bottom of the suspended platform and is used to detect the deflection angle of the deflector 6. The two sets of distance sensors are respectively located on both sides of the suspended platform and are used to detect the braking distance on both sides of the suspended platform. The extension unit 2 is located below the suspended platform, with its bottom fixed to the ground and its top having a vertically extending extension that is rotatably connected to the bottom wall of the suspended platform. The extension allows the extension unit 2 to extend or shorten according to the lifting and lowering of the suspended platform to achieve synchronous movement with the suspended platform. The deflector 6 is fixed on the extension.
[0042] Specifically, the suspended platform equipment includes a suspended platform 1, two sets of lifting devices installed on the roof, and two sets of working steel wire ropes 11, two sets of safety steel wire ropes 12, and two safety locks 13 respectively installed on both sides of the suspended platform 1; one end of each of the two sets of working steel wire ropes 11 is connected to the power output end of the two sets of lifting devices, and the other end is connected to both sides of the suspended platform 1; the top ends of the two sets of safety steel wire ropes 12 are fixed to the roof, and the bottom ends extend downward and pass through the safety locks 13.
[0043] Reference Figure 1 The extension unit 2 includes a winding machine 21 and a positioning steel rope 22. The winding machine 21 is set on the ground and located directly below the suspended platform equipment. The top end of the positioning steel rope 22 is rotatably connected to the bottom wall of the suspended platform equipment through the connecting unit 3, and the bottom end is wound around the power output shaft of the winding machine 21.
[0044] Furthermore, referring to Figure 2The connecting unit 3 includes a connector 31 and a sliding member 32. The connector 31 is rotatably mounted on the bottom wall of the suspended platform. The sliding member 32 is mounted on the connector 31, and a groove 311 is provided inside the connector 31. The sliding member 32 is vertically slidably mounted in the groove 311. A limiting block 321 is provided at the end of the sliding member 32. An elastic member 322 is provided between the limiting block 321 and the inner wall of the groove 311. The elastic member 322 is a spring. The elastic member 322 is used to provide force for the sliding member 32 to approach the suspended platform. The top end of the positioning steel rope 22 is connected to the sliding member 32. Depending on the actual installation situation, the deflector 6 can be fixed on the connector 31 or on the top of the positioning steel rope 22, as long as it can be ensured that the deflector 6 does not rotate with the suspended platform 1.
[0045] When the suspended platform 1 rotates, the positioning steel rope 22 is pulled by the winding machine 21, making the positioning steel rope 22 taut between the suspended platform 1 and the winding machine 21. Therefore, the connecting piece 31 is affected by the tension of the positioning steel rope 22, causing the connecting piece 31 and the deflector 6 to rotate relative to the suspended platform 1. With the surrounding environment as a reference, the connecting piece 31 is actually in a relatively stationary state.
[0046] Reference Figure 1-4 A telescopic rod 14 is fixedly installed on the bottom wall of the suspended platform equipment; one end of the deflector 6 is rotatably connected to one end of the telescopic rod 14; an angle detection unit is used to detect the angle between the telescopic rod 14 and the deflector 6; anti-rotation components 312 are slidably installed vertically on both sides of the connector 31; actuating components 323 are provided on both sides of the sliding component 32; the two ends of the actuating components 323 pass through the connector 31 and are connected to the two anti-rotation components 312; a limiting groove 3121 is opened on the anti-rotation component 312; after the anti-rotation component 312 slides, the limiting groove 3121 covers or disengages from the telescopic rod 14 and the deflector 6; specifically, the connector 31 and the telescopic rod 14 are both installed on the bottom wall of the suspended platform 1.
[0047] When the suspended platform 1 is in normal use, the positioning steel rope 22 is pulled by rotating the winding machine 21, causing the sliding member 32 to move downward and bringing the anti-rotation member 312 closer, and fixing the telescopic rod 14 and the deflection member 6 in the limiting groove 3121; the suspended platform 1 is fastened by the positioning steel rope 22 and two sets of working steel wire ropes 11, thereby reducing the deflection angle when the suspended platform 1 moves; when the suspended platform 1 moves, it is necessary to ensure that the winding machine 21 and the lifting device move synchronously, and the elastic member 322 can buffer the sliding member 32 when the tension of the positioning steel rope 22 is too large, so as to avoid the connecting member 31 and the sliding member 32 being squeezed hard.
[0048] When the safety lock 13 needs to be tested, the positioning steel rope 22 only needs to be taut, and the winding machine 21 does not need to provide excessive tension to the positioning steel rope 22; because the falling speed simulated by the sudden drop of the suspended basket 1 is relatively fast, there is a possibility that the sliding part 32 will move too far downward after being subjected to force, thereby locking the telescopic rod 14 and the deflector 6; to avoid the above situation, a displacement block 5 is slidably arranged in the slide groove 311; the bottom of the sliding part 32 passes through the displacement block 5 and the connecting part 31 in sequence; the displacement block 5 is located at the limit block 321. Below; the elastic element 322 is located between the limiting block 321 and the displacement block 5; multiple bolts 51 are provided at the bottom of the connecting element 31, and the multiple bolts 51 are threadedly connected to the connecting element 31; the multiple bolts 51 pass through the connecting element 31 upward and abut against the bottom wall of the displacement block 5; before the safety lock 13 needs to be tested, the multiple bolts 51 are tightened upward, and the multiple bolts 51 can push the displacement block 5 upward, thereby reducing the downward movement distance of the sliding element 32 and preventing the anti-rotation element 312 from locking the telescopic rod 14 and the deflection element 6.
[0049] Reference Figure 1 The angle detection unit includes a central control module and a CCD camera 4 installed on the suspended platform. The central control module is electrically connected to the CCD camera 4 and the distance sensor. Specifically, the data output terminals of the CCD camera 4 and the distance sensor are connected to the data input terminals of the central control module. The CCD camera 4 can transmit the image of the angle between the telescopic rod 14 and the deflector 6 to the central control module, which can identify the image and calculate the angle change curve. The distance sensor can transmit the distance data it measures to the central control module. The safety lock 13 is qualified by comparing the braking distance of the safety lock 13 with the degree of angle change of the suspended platform 1.
[0050] To improve the stability of the slider 32 during sliding, the angle detection unit, deflection member 6, telescopic rod 14, actuating member 323 and anti-rotation member 312 can be set as two, and located on both sides of the slider 32 respectively.
[0051] The working principle of the safety testing device for a safety lock on a suspended platform for high-altitude operations in this application is as follows:
[0052] During normal use, the winding machine 21 rotates and pulls the positioning steel rope 22, causing the sliding member 32 in the connecting unit 3 to move downwards along the sliding groove 311 of the connecting member 31. The actuating members 323 on both sides of the sliding member 32 simultaneously drive the anti-rotation member 312 to slide vertically until the limiting groove 3121 on the anti-rotation member 312 covers and fixes the telescopic rod 14 and the deflecting member 6. At this time, the positioning steel rope 22 and the two sets of working steel wire ropes 11 together form a constraint on the basket 1. With the synchronous movement of the winding machine 21 and the lifting device, the deflection angle of the basket 1 during movement can be greatly reduced. At the same time, the elastic member 322 deforms when the tension of the positioning steel rope 22 is too large, forming a buffer for the sliding member 32 and preventing the connecting member 31 and the sliding member 32 from being damaged by hard compression. The winding machine 21 ensures that the anti-rotation member 312 always remains fixed by appropriately increasing the tension.
[0053] Entering the safety lock 13 testing preparation stage, by tightening multiple bolts 51 at the bottom of the connecting piece 31, the displacement block 5 is pushed upward along the slide groove 311, reducing the space below the limiting block 321, thereby limiting the maximum downward movement distance of the sliding piece 32 and preventing excessive displacement of the sliding piece 32 due to excessive force. During this process, the elastic element 322 is located between the limiting block 321 and the displacement block 5, retaining the buffer function while ensuring the controllability of the test scenario through the position adjustment of the displacement block 5.
[0054] During the testing phase of safety lock 13, performance evaluation was achieved through multi-dimensional data acquisition. When simulating dangerous conditions such as the breakage of the working wire rope 11 and the sudden fall of the suspended platform 1, the suspended platform 1 tilts or descends. As the positioning wire rope 22 is kept taut by the winding machine 21, the connecting piece 31 rotates relative to the suspended platform 1 due to the tension. The telescopic rod 14 on the bottom wall of the suspended platform 1 rotates with the suspended platform 1, and the angle changes with the deflector 6 fixed on the connecting piece 31 or the positioning wire rope 22. The CCD camera 4 captures the angle image between the telescopic rod 14 and the deflector 6 in real time, and transmits it to the central control module. After image recognition, the angle change curve is generated. At the same time, the distance sensors on both sides of the suspended platform 1 transmit the braking distance data to the central control module. The central control module compares the braking distance parameter of safety lock 13 with the degree of angle change of the suspended platform 1 to comprehensively judge whether safety lock 13 meets safety standards. In addition, the angle detection related components and anti-rotation component 312 structure symmetrically set on both sides further ensure the stability of data acquisition and the reliability of the test process.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
