Technical Field

[0002] With the rapid development of the national economy, high-rise buildings are gradually increasing, and the frequency and distribution of elevators are also gradually increasing. Therefore, people are paying more and more attention to the safety of elevator use. Relevant national laws and regulations point out that it is necessary to regularly check the various parameters and indicators of elevators to prevent elevator accidents caused by aging or failure of elevator equipment. Buffers are safety components of elevator equipment. They can play an important protective role when the elevator car falls or hits the top. The function of the hydraulic buffer is to reduce vibration and noise in automated mechanical operations, convert the kinetic energy generated by moving objects into heat energy and release it into the atmosphere, and effectively stop the object in balance during the action. The main structure of the hydraulic buffer is composed of a body, an axis, a bearing, an inner tube, a piston, a hydraulic shaft, a spring, etc. When the axis is impacted by an external force, it will drive the piston to squeeze the hydraulic oil in the inner tube. After the hydraulic oil is pressurized, it will be discharged one by one from the oil discharge holes of the inner tube. At the same time, the hydraulic oil discharged from the inner tube will also flow back to the inner tube from the oil return hole of the inner tube; when the external force disappears, the spring will rebound the piston back to the starting point and wait for the next action.
