[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. Its use can greatly reduce the physical exertion of people moving between different floors and improve people's mobility efficiency, so it is very popular.

Therefore, in the existing technology, the internal components of the elevator are usually inspected and maintained periodically. For example, for the buffers of the elevator, a pressure rebound method is used to detect the buffers to display the usage status of the buffers in real time. However, in reality, there is a lack of flexible operating devices. More importantly, it is necessary to be able to adapt to the inspection needs of elevators of different models and in use.

The output end of the electric push rod is in a vertical state with the transition pad to ensure the stability of the pressure.

[0009] The top and top front end of the inspection rack are respectively installed with a control component and an inspection recording component.

[0029] Working principle:

[0030] Example 1

[0031] To quickly inspect the buffer 2, the inspection rack 3 is mounted on the outside of the buffer 2 and pressed steadily. Then, the electric push rod 6 is turned on. With the support of the inspection rack 3, the output end of the electric push rod 6 transmits pressure to the transition pad 42 inside the inspection assembly 4. When the transition pad 42 is pressed, it will synchronously drive the inspection ball 41 to move downward and squeeze the top of the buffer 2. The inverted T-shaped constraint rod 43 provides a constraint guide for the movement of the inspection ball 41 and the transition pad 42.

[0032] After the electric push rod 6 outputs the maximum stroke value, the electric push rod 6 is closed, the output end of the electric push rod 6 is reset, and the buffer 2 that loses pressure will reversely buffer the detection ball 41 and the transition pad 42, and then the detection ball 41 and the transition pad 42 are moved up on the surface of the display rod 5. The scale lines on the surface of the display rod 5 provide distance calibration, and then the highest scale line value reached by the transition pad 42 on the surface of the display rod 5 is observed to reflect the buffering status of the buffer 2. When the rising distance of the transition pad 42 does not reach the standard value mark 11, it means that the buffering performance of the buffer 2 has declined significantly and needs to be replaced in time.

[0033] Example 2

[0034] In order to inspect the buffer 2 with high precision, the inspection frame 3 can be mounted on the outside of the buffer 2 and the electromagnet 9 is started. The electromagnet 9 magnetically connects the support frame 1 to ensure the stability of the inspection frame 3. The electric push rod 6 and the camera in the inspection recording component 8 are turned on. With the support of the inspection frame 3, the output end of the electric push rod 6 transmits pressure to the transition pad 42 inside the inspection component 4. After the transition pad 42 is pressed, it will synchronously drive the detection ball 41 to move downward synchronously and squeeze the top of the buffer 2. The inverted T-shaped constraint rod 43 provides constraint guidance for the movement of the detection ball 41 and the transition pad 42.

[0035] After the electric push rod 6 outputs the maximum stroke value, the electric push rod 6 is closed, and the output end of the electric push rod 6 is reset. The buffer 2 that loses pressure will reversely buffer and push the detection ball 41 and the transition pad 42, and then make the detection ball 41 and the transition pad 42 move up on the surface of the display rod 5. The scale lines on the surface of the display rod 5 provide distance calibration, and then observe the highest scale line value reached by the transition pad 42 on the surface of the display rod 5. At the same time, the internal camera of the inspection and recording component 8 also synchronously monitors the image of the highest point reached by the transition pad 42 on the surface of the display rod 5 and transmits it to the background observation device, such as a smart phone, through the wireless transmission module in the control component 7. Then, the on-site operator and the observer of the monitoring screen compare their respective data to form a control test while ensuring the accuracy of the inspection data, thereby reflecting the buffering status of the buffer 2. When the rising distance of the transition pad 42 does not reach the standard value mark 11, it means that the buffering performance of the buffer 2 has declined significantly and needs to be replaced in time.

[0036] Example 3

[0037] When the power of the device is exhausted during use, the inspection frame 3 is mounted on the outside of the buffer 2 and the inspection frame 3 is pressed steadily. Then, the detection ball 41 and the transition pad 42 inside the inspection assembly 4 are lifted and moved upward on the surface of the display rod 5 under the guidance of the inverted T-shaped constraint rod 43 until the specified scale line position is reached. Then, the traction on the transition pad 42 is released. Under the action of gravity, the transition pad 42 synchronously drives the detection ball 41 to move downward synchronously and squeeze the top of the buffer 2. The inverted T-shaped constraint rod 43 provides a constraint guide for the movement of the detection ball 41 and the transition pad 42.

[0038] Then, the buffer 2 will push the detection ball 41 and the transition pad 42 in the reverse buffering manner, and then move the detection ball 41 and the transition pad 42 upward on the surface of the display rod 5. The scale lines on the surface of the display rod 5 provide distance calibration, and then observe the highest scale line value reached by the transition pad 42 on the surface of the display rod 5. By comparing it with the standard value under the same conditions, the buffering status of the buffer 2 can be reflected. When the rising distance of the transition pad 42 does not reach the standard value, it means that the buffering performance of the buffer 2 has declined significantly and needs to be replaced in time.
