Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective equipment technology, and in particular to a speed difference automatic control device for detection. Background Technology
[0002] With the development of the national economy, high-altitude operations are becoming increasingly frequent in industries such as power. Differential speed controllers are essential tools for fall prevention among high-altitude workers, and their performance directly affects their safety. However, in practice, many high-altitude workers are unaware of the proper use of differential speed controllers and use them without prior inspection, creating safety hazards. Therefore, a testing device is needed to ensure that differential speed controllers function correctly and to guarantee the safety of high-altitude workers.
[0003] Currently, the performance testing of speed-difference automatic controllers mainly uses tensile testing equipment. Operators connect the speed-difference automatic controller to the tensile testing equipment, set the tensile parameters, and gradually increase the tensile value at a specific rate. As the tensile force increases, the locking response of the speed-difference automatic controller is observed to determine whether it can quickly activate the braking mechanism and complete the locking action within the specified tensile threshold. This simulates the stress situation and thus tests its performance.
[0004] Regarding the technologies mentioned above, the working conditions faced by speed-differential controllers in high-altitude operations are extremely complex. When workers are climbing, moving, or experiencing sudden falls, the equipment not only has to withstand vertical tension but also horizontal swaying, impacts at irregular angles, and lateral forces generated by the tilt of the work platform. Falls during high-altitude operations are often accompanied by rapid changes in speed, and the instantaneous impact force is far greater than the load in a static tensile test. A single tensile test cannot simulate the performance of the speed-differential controller under dynamic impact, cannot accurately detect its reliability in actual use scenarios, and may easily overlook potential safety hazards.

At the same time, it is easy to disassemble and maintain, and the distance between the upper and lower clamping plates is adjustable, which is convenient to adapt to test frames of different thicknesses and improves the flexibility of the device.
[0017] Optionally, the bracket includes a connecting plate, a lifting ring, and a hook.

[0031] This application discloses a speed difference controller detection device. Example
[0032] Reference Figure 1 and Figure 2 A speed differential automatic control device includes a test frame 1. A mounting frame 11 is provided at the upper end of the test frame 1.

[0033] Reference Figure 1 and Figure 2 A pulley 111 is provided on the side of the lower clamping plate 113 away from the upper clamping plate 112. The pulley 111 is rotatably connected to the lower clamping plate 113. A bracket 12 is provided on one side of the pulley 111. The speed difference controller 121 is located at the upper end of the bracket 12. The bracket 12 supports the speed difference controller 121. The speed difference controller 121 includes a safety rope 122. A counterweight 116 is provided at the lower end of the pulley 111. The safety rope 122 passes through the pulley 111 and is hooked to the counterweight 116. A release device is provided above the test frame 1.

[0037] Reference Figure 1 and Figure 2 The upper end of the test frame 1 is equipped with a horizontal dynamic detection component.

When performing a horizontal dynamic performance test on the speed difference controller 121, the speed difference controller 121 is installed at the lower end of the pulley 111. The safety rope 122 is connected to the counterweight 132. The release device releases the counterweight 132, which falls under the action of gravity. The falling counterweight provides tension to the safety rope 122. The detachable crossbeam 131 provides a stop for the safety rope 122, allowing the safety rope 122 to move horizontally. At the same time, some friction is generated between the safety rope 122 and the detachable crossbeam 131, thereby testing the horizontal dynamic performance of the safety rope 122 and improving the accuracy of the testing device.
[0038] Reference Figure 2The detachable crossbeam 131 includes two inclined rods 1312 and a moving rod 1311. The two inclined rods 1312 are located on both sides of the test frame 1 and are detachably connected to the test frame 1, which facilitates the adjustment of the position of the inclined rods 1312 and improves the flexibility of the device. The moving rod 1311 is located between the two inclined rods 1312. Both ends of the moving rod 1311 are provided with bolts 1313. The bolts 1313 pass through the moving rod 1311 and the inclined rods 1312 at one time. The side of the bolts 1313 away from the inclined rods 1312 is provided with corresponding nuts 1314. The bolts 1313 and the corresponding nuts 1314 are threadedly connected, realizing the detachability of the detachable crossbeam 131 structure, which facilitates installation and disassembly operations.

[0039] The implementation principle of the speed difference automatic controller detection device in this application embodiment is as follows: The release device releases the counterweight block 116, which descends under the action of gravity. The descent of the counterweight block 116 drives the safety rope 122 to descend, simulating the load release scenario in actual work. The vertical direction is detected. After the vertical direction detection is completed, the position of the speed difference automatic controller 121 is adjusted so that the speed difference automatic controller 121 is connected to the counterweight block 132. The release device drives the counterweight block 132 to descend, which drives the safety rope 122 to move in the horizontal direction. At the same time, the safety rope 122 and the detachable crossbeam 131 generate partial friction, thereby detecting the horizontal dynamic performance of the safety rope 122 and improving the detection accuracy of the detection device.
