Description

Technical Field

[0001] This utility model relates to the field of safety rope testing technology, specifically a safety rope and safety belt testing platform. Background Technology

[0002] Currently, the testing equipment used for seat belt performance testing consists of separate test frames for static and dynamic tests. Static testing involves applying a certain tensile force to the seat belt, maintaining that force for a period of time, and then observing whether the seat belt tears or deforms. Dynamic testing, on the other hand, involves placing the seat belt against a heavy object (typically by threading the seat belt over a weight). Figure 9 Connect the safety belt to the simulated human body shown, suspend the safety belt to a certain height and then release it, and then observe whether the safety belt is torn or deformed.

[0003] However, currently, static and dynamic tests for seat belts are conducted separately. Because these are independent systems, they cannot be centralized, resulting in a large footprint. Furthermore, testing seat belts requires transporting simulated human bodies to different locations, making the process cumbersome. Therefore, we propose a safety rope and seat belt testing platform.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Reference Figures 1 to 8This utility model provides a technical solution: a safety rope and safety belt test bench, including a test platform 1 and a first-row crane 3, a second-row crane 4 and a third-row crane 10. Each of the first-row crane 3, the second-row crane 4 and the third-row crane 10 is equipped with an electric hoist 11. The electric hoist 11 is used to lift heavy objects. Therefore, in order to facilitate the lifting of the electric hoist 11, a connecting buckle or hook is provided at the bottom of the electric hoist 11 to facilitate the connection of heavy objects.

[0029] The bottom of the testing platform 1 is supported on a base 23 by multiple support pillars 22. The support pillars 22 are distributed at the bottom center and edges of the testing platform 1 to ensure sufficient stability. Figure 1 As shown, the top of the testing platform 1 is provided with a first testing port 8, and a hoist 5 is provided above the first testing port 8. Figure 1 and Figure 2 As shown, the hoist 5 is a tripod hoist. During installation, the three supports of the tripod hoist should be installed at the edge of the first detection port 8. It should be noted that there is also a connecting buckle or hook at the bottom of the hoist 5 (the following will explain the application of the connecting buckle) to facilitate the connection of heavy objects.

[0030] like Figure 2 and Figure 8 As shown, corresponding to the first detection port 8, a movable platform 15 is provided below the first detection port 8. Connecting frames 19 are provided on both sides of the movable platform 15, with the connecting frames 19 tilted upwards and forming a "V" shape. During installation, the two ends of the connecting frames 19 are slidably mounted on the support beam 21. Specifically, the two ends of the connecting frames 19 are slidably mounted on the slide rail via sliders. The slide rail is mounted on the support beam 21, and the two ends of the support beam 21 are fixed to the support column 22. At this time, the movable platform 15 can move along the support beam 21. In actual use, the movable platform 15 can move along the support beam 21 to the outside below the first detection port 8, or it can move along the support beam 21 to the area below the first detection port 8.

[0031] The purpose of the mobile platform 15 is to provide a platform for people, because a heavy object is suspended below the hoist 5. Figure 9 The human body model is equipped with a safety rope or safety belt, and the weight is lifted by the hoist 5. At this time, the human body model is suspended in the air. The mobile platform 15 can be moved to below the first detection port 8 to facilitate the operator to stand on the human body model. It should be noted that the mobile platform 15 must be positioned carefully during use to avoid contact with the human body model.

[0032] Furthermore, such as Figure 1As shown, a second inspection port 9 is provided on one side of the first inspection port 8. The second crane 4 is located above the first inspection port 8 and the second inspection port 9. It should be noted that the hoist 5 is located below the second crane 4. The two ends of the second crane 4 are connected to the inspection platform 1 through the first column 7.

[0033] Based on the above embodiments, it should be noted that the second crane 4 and the hoist 5 are both tested for safety ropes and safety belts. Before the test, the safety rope or safety belt needs to be put on the human body model (the following description uses the safety rope as an example). At least one release device and at least one dynamic sensor 18 also need to be prepared. The release device and dynamic sensor 18 can be taken away at will, that is, they can be used in different test stages.

[0034] When the hoist is in use, a dynamic sensor 18 is attached to the connecting buckle of the hoist. The buckle below the dynamic sensor 18 is connected to the safety rope on the human body model. When the hoist 5 lifts the human body model, the dynamic sensor 18 can monitor the change in the tension of the safety rope.

[0035] When the second crane 4 is in use, the human model can also be lifted by the electric hoist 11 on the second crane 4 and moved above the second detection port 9. A dynamic sensor 18 is also hung below the electric hoist 11. A release hook is attached to the buckle below the dynamic sensor 18. The release hook is connected to the safety rope on the human model. When the electric hoist 11 lifts the human model, the human model is released through the release hook. The human model falls from the second detection port 9. At this time, the dynamic sensor 18 can test the data of the safety rope when the human model falls.

[0036] Furthermore, the third crane 10 is located inside one side of the second inspection port 9, and a fixing device is provided below the third crane 10, such as... Figure 1 and Figure 2 As shown, the fixing device includes a connecting seat 13 located below the third crane 10. The top of the connecting seat 13 is provided with a connecting hook 14. There is at least one connecting hook 14. During installation, the connecting seat 13 and both ends of the third crane 10 are connected to the support column 22 respectively.

[0037] The third crane 10 is used for static tensile testing of the mannequin. Before testing, the safety rope on the mannequin needs to be connected to the connecting hook 14. It should be noted that the tension of this rope must be greater than the maximum tension of the safety rope to prevent it from breaking. Then, a dynamic sensor 18 is hung below the electric hoist 11 below the third crane 10. The hook below the dynamic sensor 18 is connected to the hook at the top of the mannequin. Controlling the electric hoist 11 will lift the mannequin. The electric hoist 11 applies a certain force (generally 1.5 tons) to the safety rope, at which point the safety rope is pulled very taut. This is maintained for at least one minute, during which time the condition of the safety rope is observed and whether any breakage occurs.

[0038] Furthermore, the first crane 3 is located above one side of the testing platform 1, and both ends of the first crane 3 are connected to the testing platform 1 via the second column 20. A track fall arrester 17 is installed below the first crane 3. Figure 1 As shown, the track fall arrester 17 is installed on the support frame, which includes two mounting brackets 16 that are perpendicularly connected to the base 23. The mounting brackets 16 are connected by multiple connecting rods 24, and the track fall arrester 17 is installed on the connecting rods 24.

[0039] The first crane 3 here is used to test the performance of the safety belt during a fall. The safety belt on the mannequin is attached to the track fall arrester 17. A release hook is attached below the electric hoist 11 at the first crane 3. The release hook lifts the mannequin and raises it above the testing platform 1. Then, the release hook releases the mannequin. It is important to note that the track fall arrester 17 is equipped with sensors to test the performance of the safety belt during a fall.

[0040] Furthermore, such as Figure 7 and Figure 8 As shown, an operating platform 27 is provided below the first crane 3. The operating platform 27 is used for people to stand on, so as to facilitate the operation of the human body model lifted by the first crane 3. The two ends of the operating platform 27 are connected to the second column 20 respectively. The side of the operating platform 27 away from the first crane 3 is connected to the detection platform 1 through the second ladder 29. The second ladder 29 not only makes it convenient for operators to climb onto the operating platform 27, but also provides support for the operating platform 27.

[0041] To facilitate operators accessing testing platform 1, such as Figure 7 As shown, one side of the detection platform 1 is connected to the base 23 via the first ladder 26.

[0042] Based on the above implementation, it can be further optimized. A protective railing 6 is provided at the edge of the first detection port 8, and a first fence 25 is also provided at the edge of the detection platform 1. The first fence 25 has an opening at the first ladder 26 for operators to enter and exit. A second guardrail 28 is installed at the edge of the operating platform, and the second guardrail 28 also has an opening for operators to enter and exit at the corresponding position of the second ladder.

[0043] Based on the above implementation, it can be further optimized. A buffer pit 12 is provided on the base 23 below the second detection port 9. The buffer pit 12 contains a buffer material, such as a buffer pad, fine sand or sponge.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
