[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0024] like Figures 1 to 6As shown, this utility model provides an insulated rope ladder load-bearing testing device, including a base 11. The base 11 has a boss 12, which serves to elevate and position other components. The boss 12 has two sets of support plates 13, with pre-cut slots on it. The bottom of the support plates 13 can be precisely inserted into these slots, thus securing them firmly on the boss 12. The two sets of support plates 13 together support a mounting plate 14, which provides a mounting platform for the testing components. Between the two sets of support plates 13, two sets of optical axes 15 and a sliding plate 16 are arranged. The top of the optical axis 15 is connected to the mounting plate 14, and the bottom is connected to the boss 12, providing vertical support and guidance. The sliding plate 16 has two sets of guide holes, through which the optical axes 15 pass, allowing the sliding plate 16 to move up and down along the optical axes 15. A hanging plate 17 is mounted on one end of the sliding plate 16. Multiple sets of L-shaped, equidistantly arranged hooks 18 are provided on one end of the hanging plate 17. These hooks 18 are used to suspend the insulated rope ladder, facilitating load-bearing testing. A control module 19, which can be an STC89C52 microcontroller, is located on one side of the boss 12. The control module 19 controls the operation of the entire testing device. A fixing component is also provided on one end of the boss 12 to secure the relevant components during the testing process. This layout allows the components to cooperate with each other, establishing the basic framework for the load-bearing test of the insulated rope ladder.

[0025] like Figures 2 to 4 As shown, the fixing assembly includes a fixing plate 21 and a limiting plate 22. The fixing plate 21 is placed on the base 11, providing a supporting foundation for the entire fixing assembly. The fixing plate 21 has two sets of support columns, and limiting shafts are set on the support columns. Here, the diameter of the support columns is larger than that of the limiting shafts. The fixing plate 21 has two sets of limiting holes, and the limiting shafts can be inserted into the limiting holes. Because the diameter of the support columns is larger than that of the limiting shafts, the limiting plate 22 is restricted to sliding only on the limiting shafts. The support columns leave installation space for the subsequent tension gauge 23. In this way, the limiting shaft and the fixing plate 21 are connected. The limiting plate 22 can then perform corresponding functions by cooperating with the limiting shafts, thereby effectively fixing other components in the testing device.

[0026] The fixing assembly also includes a tension gauge 23. The tension gauge 23 can be a PSM-300N mechanical push-pull force gauge, positioned between the fixing plate 21 and the limiting plate 22. Both the top of the fixing plate 21 and the bottom of the limiting plate 22 have retaining rings, and both ends of the tension gauge 23 are connected to these two sets of retaining rings respectively. During testing, the tension gauge 23 can measure the change in tension between the fixing plate 21 and the limiting plate 22 in real time, thus providing data support for judging the load-bearing capacity of the insulated rope ladder.

[0027] A fixing block 24 is provided on the limiting plate 22. A through square groove is formed on the top and one side of the fixing block 24, through which the rope ladder passes. A cylinder 25 is installed at one end of the fixing block 24, and a clamping plate 26 is mounted on the shaft end of the cylinder 25. When the cylinder 25 is activated, the shaft end extends, driving the clamping plate 26 to move. The clamping plate 26 passes through the gap between the rope ladder steps, and the fixing shaft on the clamping plate 26 is engaged with one side of the fixing block 24, thus fixing the rope ladder.

[0028] like Figures 2 to 3 , Figure 5 , Figure 6 As shown, the test assembly includes two sets of bearing housings 27 and a motor 28. A test shaft 29 is housed within the bearing housings 27, providing support and rotation for the test shaft 29. Two sets of sprockets 31 are located between the two sets of bearing housings 27, and the sprockets 31 are fitted onto the test shaft 29, rotating as the test shaft 29 rotates. Synchronous pulleys are provided at both ends of the motor 28 and the test shaft 29, and the two sets of synchronous pulleys are connected by a synchronous belt. After the motor 28 starts, it drives the test shaft 29 to rotate via the synchronous belt, which in turn drives the sprockets 31 to rotate, providing power to the entire test assembly.

[0029] The test assembly also includes two sets of chains 32 and counterweights 33. A groove is provided on one side of the support plate 13, and the counterweight 33 is engaged between the two grooves, allowing it to move up and down within the grooves. Connecting seats 34 are provided at both ends of the chains 32. One end of the chain 32 is connected to the slide plate 16 via the connecting seat 34, and the chain 32 passes over the sprocket 31. The other end is connected to the counterweight 33 via the connecting seat 34. When the sprocket 31 rotates, it drives the chain 32 to move, thereby causing the slide plate 16 and the counterweight 33 to move along their respective tracks. By increasing or decreasing the weight of the counterweight 33, different load-bearing conditions can be simulated, thus achieving a load-bearing test on the insulated rope ladder.

[0030] like Figures 2 to 3 As shown, the base 11 is also provided with two sets of rotating seats 35, and rotating shafts 36 are inserted inside the rotating seats 35. Multiple sets of barbs are provided on the rotating shafts 36. These rotating shafts 36 and barbs are used to store the part of the insulating rope ladder to be tested. After the test is completed, the insulating rope ladder can be wound orderly on the rotating shafts 36 and fixed with the barbs, which facilitates the sorting and storage of the insulating rope ladder.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using the insulated rope ladder load-bearing test device, the insulated rope ladder is hung on the hook 18 of the hanging plate 17. The motor 28 is started, and the motor 28 drives the test shaft 29 to rotate via the synchronous belt. The test shaft 29 drives the sprocket 31 to rotate, and the sprocket 31 pulls the chain 32. One end of the chain 32 is connected to the slide plate 16, and the other end is connected to the counterweight 33, so the slide plate 16 and the counterweight 33 begin to move. As the counterweight 33 moves, weight is continuously applied to the insulated rope ladder, simulating the load-bearing situation in actual use.

[0033] At this point, the fixing components come into play. The limiting shaft on the fixing plate 21 cooperates with the limiting plate 22, and the tension gauge 23 measures the tension, ensuring the stability of the device structure and the measurability of the force throughout the test. The cylinder 25 on the limiting plate 22 drives the clamping plate 26, which can fix the insulated rope ladder locally. Meanwhile, the rotating shaft 36 in the rotating seat 35 on the base 11 and its barbs, along with the control module 19, can control the motor 28 and other components, adjusting the test progress and parameters. By observing the value of the tension gauge 23 and the state of the insulated rope ladder under different counterweights, the load-bearing capacity test of the insulated rope ladder can be completed.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
