[0032] The present invention also provides a method for using a detection device for an elevator buffer structure, as follows: S100. Check whether all parts of the device are intact, including the base 1, mounting frame 2, protective door 3, locking mechanism 4, test table 5, positioning assembly 6, buffer assembly 7, etc. for damage. Confirm that the electrical equipment such as motor 601, displacement sensor 608, pressure sensor 705, high-speed camera 11 are connected normally and can work normally. Place the device in a stable and safe working area to ensure that there are no obstacles around that affect the operation. The innovation of this device lies in the use of a unique locking mechanism 4. Compared with traditional detection devices, it can more conveniently and stably realize the opening and closing of the protective door 3 through the cooperation of the tooth plate 402, the limit plate 403, the rotating rod 406 and the gear 407, which greatly improves the convenience of operation and the safety during the detection process.

Start the detection program to simulate the condition of the elevator falling or overspeed descent. At this time, the displacement sensor 608 measures the displacement change of the buffer structure, the pressure sensor 705 measures the force condition, and the high-speed camera 11 records the detection process. During the detection process, the staff can view the detection situation in real time through the observation window 13. The buffer component 7 of the device is a major innovation. It is composed of a second spring 702 and a damper 704. When simulating impact, it can effectively ensure the stability of the overall structure of the device, improve the buffering performance of the device, and ensure that the detection data is more accurate. At the same time, the setting of the high-speed camera 11 can record the detection process in real time, providing more comprehensive information for subsequent analysis, which is also an important innovation that distinguishes it from traditional detection devices.

[0036] S500. After the test is completed, turn the hand wheel 12 to open the protective door 3 and take out the buffer structure after the test. Arrange the device and turn off the power of the motor 601, high-speed camera 11 and other equipment. Analyze and process the test data, record key data such as buffer stroke, force size and change, and evaluate the performance of the buffer structure.

The detection program is started to simulate the elevator falling or overspeed descent condition. At this time, the displacement sensor (608) measures the displacement change of the buffer structure, the pressure sensor (705) measures the force condition, and the high-speed camera (11) records the detection process. During the detection process, the staff can view the detection situation in real time through the observation window (13); S500, after the test is completed, the hand wheel (12) is turned to open the protective door (3), the buffer structure after the test is taken out, the device is arranged, the power supply of the motor (601), the high-speed camera (11) and other equipment is turned off, the test data is analyzed and processed, and key data such as the buffer stroke, force size and change are recorded to evaluate the performance of the buffer structure.
