Description

Technical Field

[0001] This utility model relates to the field of fall arrestor technology, specifically to a rope release mechanism for fall arrestor release testing. Background Technology

[0002] A fall arrester disengagement test is a test used to evaluate and verify the performance of fall arresters. Fall arresters are essential safety devices, commonly used in high-altitude operations or mine hoisting systems to prevent personnel or equipment from falling in the event of an accident. The main purpose of this test is to ensure that the fall arrester can function effectively in emergency situations, ensuring the safety of personnel and equipment. The test simulates a fall that might occur in actual use, separating the protected object (such as a cage) from the hoisting system in a specific manner, and observing whether the fall arrester can activate promptly and effectively prevent the fall. This test is crucial for ensuring the reliability and safety of fall arresters.

[0003] However, existing fall arrestor release tests generally rely on users manually pulling the rope to achieve the release action. While this method is feasible for lower heights or close-range tests, it reveals significant limitations when conducting release tests at higher altitudes. Because operators must apply force at close range or manually pull from a distance using a simple traction rope, this not only increases the difficulty and uncertainty of the operation but also leads to uneven pulling force, angle deviations, or reaction delays, resulting in unsmooth and asynchronous release actions, affecting the accuracy and repeatability of the test. Utility Model Content

[0004] The purpose of this invention is to provide a rope-release mechanism for fall arrester release testing, addressing the problems mentioned in the background section. Existing fall arrester release tests often rely on manual rope pulling, which is inconvenient and difficult to control. When working at heights, uneven tension, angle deviations, or delays can easily lead to asynchronous release, affecting test accuracy. This method also suffers from poor safety and repeatability, failing to meet the requirements of high-altitude testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rope release mechanism for a fall arrestor release test, comprising a padlock, wherein the surface of the padlock is provided with a release assembly, the release assembly includes a first limiting block, a second limiting block and a fixing plate, and a running plate is rotatably connected to both the front and rear sides of the padlock, the surface of the running plate is connected to the first limiting block, and a cutting assembly is provided on the front surface of the padlock.

[0006] Furthermore, a connecting block is fixedly connected to the surface of the fixing plate, and a cylinder is fixedly connected to the top of the connecting block.

[0007] Furthermore, a fixed rod is fixedly connected to the output end of the cylinder, and a movable frame is fixedly connected to the top end of the fixed rod.

[0008] Furthermore, push rods are connected to opposite sides of the two running plates, and the surfaces of the push rods are movably connected to the inner side of the moving frame.

[0009] Furthermore, the cutting assembly includes a protective housing, and a motor is fixedly connected to the inner cavity of the protective housing.

[0010] Furthermore, a round rod is provided through both the front and rear sides of the padlock, and pulleys are respectively installed on the surface of the round rod and the output shaft of the motor, and the two pulleys are connected by belt drive.

[0011] Furthermore, two placement blocks arranged symmetrically front to back are fixedly connected to the surface of the round rod, and a gripper cylinder is fixedly connected to one side of each placement block.

[0012] Furthermore, a cutting groove plate and a blade are fixedly connected to both sides of the output end of the gripper cylinder, and the cutting groove plate and the blade are used in cooperation with each other.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] This invention features a disengagement component and a cutting component, providing two switchable rope-release modes, significantly improving the flexibility and reliability of the test. The disengagement component, through a coordinated design of inter-structure components such as a cylinder-driven push rod, a running plate, and a limiting plate, achieves smooth and synchronous disengagement of the test object, ensuring a controllable and highly repeatable process. The cutting component, on the other hand, uses a motor to drive a gripper cylinder to rotate and a blade to precisely cut the rope, suitable for test scenarios requiring complete rope separation. The two modes can be freely switched according to actual test conditions and safety requirements, avoiding the operational risks and uncertainties of traditional manual rope pulling and effectively preventing structural interference problems that may occur during mechanical disengagement. This dual-mode design not only enhances the safety and adaptability of the test process but also provides reliable technical support for verifying the performance of fall arresters under different working conditions, strongly guaranteeing the smooth conduct of rope-release tests and the accuracy of data.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: A rope release mechanism for a fall arrestor release test, such as... Figures 1-6As shown, the device includes a padlock 1, with a release assembly 2 on its surface. The surface of the padlock 1 has a hook hole for easy connection of the hanging hook lock. The release assembly 2 includes a first limiting block 28, a second limiting block 29, and a fixing plate 21. The second limiting block 29 is rotatably connected to the padlock 1. The first limiting block 28 and the second limiting block 29 are specifically components in the fall arrestor for hooking the experimental object. Both the front and rear sides of the padlock 1 are rotatably connected to a running plate 24. The surface of the running plate 24 is connected to the first limiting block 28, and the first limiting block 28 and the second limiting block 29 are in contact, thus facilitating the hooking of the experimental object and rope to be tested. The front surface of the padlock 1 is provided with a cutting assembly 3. The overall function of the cutting assembly 3 is to allow the user to cut the hooked rope for release, thereby increasing the selectivity of the experimental release. A connecting block 22 is fixedly connected to the surface of the fixing plate 21.

[0026] like Figures 2-6 As shown, a cylinder 23 is fixedly connected to the top of the connecting block 22. This cylinder 23 can be transformed into an electric telescopic rod according to actual conditions. A fixed rod 25 is fixedly connected to the output end of the cylinder 23. A movable frame 26 is fixedly connected to the top of the fixed rod 25. A push rod 27 is connected to the opposite side of the two running plates 24. The surface of the push rod 27 is movably connected to the inner side of the movable frame 26. The cutting assembly 3 includes a protective box 31. The surface of the protective box 31 is fixedly connected to the front side of the padlock 1. A motor 32 is fixedly connected to the inner cavity of the protective box 31. The user can place the battery on the surface of the protective box 31 or the padlock 1 to provide power to the motor 32. The padlock 1 has a circular rod 33 running through its front and rear sides. The circular rod 33 is rotatably connected to the padlock 1 and the protective box 31 through the contact area of ​​the circular rod 33. The surface of the circular rod 33 and the output shaft of the motor 32 are respectively equipped with pulleys 34, and the two pulleys 34 are connected by belt drive. Two placement blocks 35 are fixedly connected to the surface of the circular rod 33 and are arranged symmetrically in front and behind. A gripper cylinder 36 is fixedly connected to one side of the placement block 35. A cutting groove plate 37 and a blade 38 are fixedly connected to both sides of the output end of the gripper cylinder 36, and the cutting groove plate 37 and the blade 38 cooperate with each other. The cutting groove plate 37 has a cutting groove to facilitate the use of the blade 38.

[0027] Specifically, when conducting a rope-detachment test on the experimental object, cylinder 23 can be activated. Cylinder 23 pushes the fixed rod 25 and the moving frame 26 downwards. The moving frame 26 drives the push rod 27 to move synchronously, and the push rod 27 in turn drives the running plate 24 to move. At this time, the running plate 24 rotates downwards about the axis connected to the padlock 1, causing the first limiting block 28 to move forward and pushing the second limiting block 29 to rotate downwards about the padlock 1, ultimately achieving the overall detachment of the experimental object and its rope, completing the rope-detachment action. In addition, the user can also choose a second rope-detachment method: start the motor 32, which drives the pulley 34 to rotate. The pulley 34 drives the placement block 35 to rotate through the round rod 33, causing the gripper cylinder 36 to flip accordingly. By controlling the rotation of the round rod 33, the gripper cylinder 36 can be flipped to the side away from the second limiting block 29, thereby avoiding interference or collision during the detachment process. Subsequently, the gripper cylinder 36 is activated, causing the cutting groove plate 37 and the blade 38 to move relative to each other, cutting the suspended rope and causing the suspended experimental object to fall off.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
